Introduct'ion This Stormwater Pollution Prevention Plan (SWPPP) manual has been prepared to address the requirements of the U.S. Environmental Protection Agency(EPA) National Pollutant Discharge Elimination System (NPDES) Construction General Permit(CGP)for Stormwater Discharges from Construction Activity(2022, USEPA). A copy of the 2022 CGP is included in Appendix B. The CGP gives Project Operators of construction activities that meet the eligibility conditions of Part 1.1 of the 2022 CGP,authorization to discharge: > stormwater identified in Part 1.2.1 of the 2022 CGP,and > non-stormwater associated with some construction activities as defined in part 1.2.2 of the 2022 CGP > provided that adequate measures are taken to prevent pollution to receiving waters. This manual is specific to project sites in Massachusetts,where the EPA is the permitting authority for stormwater discharges from construction sites. a. How to Use this Manual This manual does not become a CGP-compliant SWPPP until the Project Operators: > finalize the SWPPP by completing the initial activities indicated on the following pages,and > by maintaining the SWPPP during the construction period in accordance with the 2022 CGP. Before the project activities begin,the Project Operators must review this manual,fill out relevant information in the spaces provided (or attach additional pages as necessary)and update and/or revise as necessary. Within the draft SWPPP presented to the Project Operators,VHB has provided instructions for the Project Operator in red text.These instructions are intended to guide the Project Operators in completing those portions of the SWPPP that are within their purview and control. Once the appropriate information in response to the red text directions is inserted within the SWPPP,the red directions should be deleted prior to the filing of a NOI with the EPA for the project. Optional items are highlighted in yellow to indicate that these may be added if needed. If not needed,the highlighted sections of the SWPPP can be deleted. b. What is a Project Operator? The 2022 CGP provides permit coverage for Project Operators(Operator)to discharge stormwater from construction sites.CGP Part 1.1.1 describes an Operator is any party associated with a construction project that meets either of the following two criteria: vii Contact Information/Responsible Parties ............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................ > The party has operational control over construction plans and specifications, including the ability to make modifications to those plans and specifications;or > The party has day-to-day operational control of those activities at a project,which are necessary to ensure compliance with a SWPPP for the site or other permit conditions(e.g.,they are authorized to direct workers at a site to carry out activities required by the SWPPP or comply with other permit conditions). Operators are responsible for maintaining compliance with the terms of the 2022 CGP. All operators who wish to obtain coverage to discharge stormwater under the 2022 CGP must submit and certify their own NO1 to the Environmental Protection Agency(EPA). The Site Owner,the Project Owner,and the site General Contractor, may all be considered Operators. In some cases, project subcontractors may also be considered Operators. c. Eligibilityfor Permit Coverage To be covered under the 2022 CGP,a party must meet the eligibility conditions and follow the requirements for obtaining permit coverage.To be eligible for coverage: > You must be an Operator of a construction site for which discharges will be covered under this permit. > The project's construction activities: > will disturb one(1)or more acres of land,or less than one(1)acre of land if the project is part of a larger common plan of development that will ultimately disturb one(1)or more acres of land. > have been designated by EPA as needing permit coverage under 40 CFR 122.26(a)(1)(v)or 40 CFR 122.26(b)(15)(ii). > Discharges from your site are not already covered by a different NPDES permit for the same discharge or in the process of having coverage under a different NPDES permit for the same discharge denied, terminated,or revoked. > The project can demonstrate compliance with one of the criteria in the Endangered Species Protection Section of the Notice of Intent that will be submitted for coverage under this permit,Per Part 1.4,with respect to the protection of the federally listed endangered or threatened species and federally designated critical habitat under the Endangered Species Act. > The project has completed the screening process in Appendix A of the 2022 CGP relating to the protection of historic properties. > The project complies with all requirements in Part 9 of the 2022 CGP. > The project meets the requirements relevant to water quality impacts to designated waters(Section 3.2. Refer to Part 1.1.8 and 1.1.9 of the 2022 CGP). Project Operators must file and certify an NO1 at least fourteen (14)days prior to the start of project activities.

Compliance Requirements Compliance with the 2022 CGP is achieved by: > Developing a Stormwater Pollution Prevention Plan (SWPPP); > Identifying project operators and responsible parties and obtaining authorization to perform permit compliance activities.(Section 2.1 and Appendix C); > Submitting and certifying a Notice of Intent(NO1)to the Environmental Protection Agency(EPA) Construction General Permit Program; > Installing a sign or other notice posted conspicuously at a safe, publicly accessible location, in close proximity to the project site. At a minimum,the notice shall include: The NPDES Permit tracking number, A contact name and phone number for obtaining additional project information, The location where an EPA inspector or a member of the public may access a copy of the current SWPPP, The statement:"If you observe indicators of stormwater pollutants in the discharge or in the receiving waterbodies,contact the EPA through the following website:,..„,„ s: . . ov it forc ire int ire ort,...., nviironmenta violations. ...................................................................................................................................................................................................... > Updating this SWPPP as necessary and maintaining compliance with the CGP and any and all Orders of Conditions during construction period activities;and > Maintaining an updated copy of the SWPPP on the project site. e. Document Control Once the project is authorized for coverage under the 2022 NPDES CGP the SWPPP must include the following: > 2022 NPDES CGP; > A copy of you NO1 submitted to EPA along with correspondence with EPA related to coverage under the permit; > A copy of the acknowledgment letter received from NeT assigning your NPDES ID(Permit Tracking Number); A current copy of the SWPPP must be maintained at the site or an easily accessible location so that it can be made available at the time of an on-site inspection or upon request by: > EPA > a state,tribal or local agency that approves stormwater management plans; > the operator of a storm sewer system receiving discharges from the site; > or representatives of the U.S. Fish and Wildlife Service(USFWS)or the National Marine Fisheries Service (N M FS). If an on-site location is unavailable for storing these documents,a notice of the plan's location must be posted near the main entrance of the construction site. These documents may be made available to the general public by federal,state,or local agencies.These documents must be retained for at least 3 years from the date that the permit coverage expires or is terminated. ix Contact Information/Responsible Parties ............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

"Dewatering" is defined as"the act of draining accumulated stormwater and/or ground water from building foundations,vaults,and trenches, or other similar points of accumulation." > Route dewatering water through a sediment control (e.g.,sediment trap or basin, pumped water filter bag) designed to prevent discharges with visual turbidity; For the purposes of this permit,visual turbidity is present where there is a sediment plume in the discharge or the discharge appears cloudy,or opaque,or has a visible contrast that can be identified by an observer. > Do not discharge visible floating solids or foam; > The discharge must not cause the formation of a visible sheen on the water surface,or visible oily deposits on the bottom or shoreline of the receiving water.Use an oil-water separator or suitable filtration device (such as a cartridge filter)designed to remove oil, grease,or other products if dewatering water is found to or expected to contain these materials; > To the extent feasible, use well-vegetated (e.g.,grassy or wooded),upland areas of the site to infiltrate dewatering water before discharge. You are prohibited from using receiving waters as part of the treatment area; > To prevent dewatering-related erosion and related sediment discharges: • Use stable,erosion-resistant surfaces(e.g.,well-vegetated grassy areas,clean filter stone,geotextile underlayment)to discharge from dewatering controls; • Do not place dewatering controls,such as pumped water filter bags,on steep slopes and at all points where dewatering water is discharged,comply with the velocity dissipation requirements of Part 2.2.11 2022 CG P. > For backwash water,either haul it away for disposal or return it to the beginning of the treatment process; > Replace and clean the filter media used in dewatering devices when the pressure differential equals or exceeds the manufacturer's specifications;and > Comply with dewatering-specific inspection requirements in Part 4 2022 CGP. 7.2 Procedures 7.2.1 Turbidity Monitoring 7.2.1.1 Water Quality-based Effluent Limitations General note: All references below refer to the 2022 Construction General Permit 70 Turbidity Benchmark Monitoring for Dewatering Discharges ............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................ 7.2.1.2 General Effluent Limitation to Meet Applicable Water Quality Standards Discharges must be controlled as necessary to meet applicable water quality standards. Discharges must also comply with any additional State or Tribal requirements that are in Part 9. In the absence of information demonstrating otherwise, EPA expects that compliance with the conditions in this permit will result in stormwater discharges being controlled as necessary to meet applicable water quality standards. If at any time you become aware,or EPA determines,that discharges are not being controlled as necessary to meet applicable water quality standards,you must take corrective action as required in Parts 5.1 and 5.2,and document the corrective actions as required in Part 5.4. EPA may insist that you install additional controls(to meet the narrative water quality-based effluent limit above)on a site-specific basis,or require you to obtain coverage under an individual permit,if information in your N01 or from other sources indicates that your discharges are not controlled as necessary to meet applicable water quality standards.This includes situations where additional controls are necessary to comply with a waste load allocation in an EPA-established or approved TMDL. If during your coverage under a previous permit,you were required to install and maintain stormwater controls specifically to meet the assumptions and requirements of an EPA-approved or established TMDL(for any parameter)or to otherwise control your discharge to meet water quality standards,you must continue to implement such controls as part of your coverage under this permit. 7.2.1.3 Water Quality-based Conditions for Sites Discharging to Certain Impaired and High Quality Receiving Waters For any portion of the site that discharges to a sediment or nutrient-impaired water or to a water that is identified by your State,Tribe,or EPA as Tier 2,Tier 2.5,or Tier 3 for antidegradation purposes,and you must comply with the stabilization deadline specified in Part 2.2.14b.iii.,you must comply with the inspection frequency specified in Part 58. Refer to Appendix A for definitions of"impaired water"and"Tier 2,""Tier 2.5,"and "Tier 3"waters. For assistance in determining whether your site discharges to impaired waters, EPA has developed a tool that is available at httl oo s. For assistance in determining whether your site discharges to a Tier 2,2.5,or 3 water, refer to the list of such waters at.h.ttj tools and,....tt m at s. If you qualify for any of the reduced inspection frequencies in Part 4.4,you may conduct inspections in accordance with Part 4.4 for any portion of your site that discharges to a sensitive water. If you discharge to a water that is impaired for a parameter other than a sediment-related parameter or nutrients, EPA will inform you if any additional controls are necessary for your discharge to be controlled as necessary to meet water quality standards.These controls might include those necessary for your discharge to be consistent with the assumptions of any 71 Turbidity Benchmark Monitoring for Dewatering Discharges ............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................ available waste load allocation in any applicable TMDL. In addition, EPA may require you to apply for and obtain coverage under an individual NPDES permit. In addition,on a case-by-case basis, EPA may notify operators of new sites or operators of existing sites with increased discharges that additional analyses,stormwater controls,and/or other measures are necessary to comply with the applicable antidegradation requirements,or notify you that an individual permit application is necessary. If you discharge to a water that is impaired for polychlorinated biphenyls(PCBs)and are engaging in demolition of any structure with at least 10,000 square feet of floor space built or renovated before January 1, 1980,you must: > Implement controls to minimize the exposure of PCB-containing building materials, including paint,caulk, and pre-1980 fluorescent lighting fixtures,to precipitation and to stormwater;and > Ensure that disposal of such materials is performed in compliance with applicable State, Federal, and local laws. Examples of controls to minimize exposure of PCBs to precipitation and stormwater include separating work areas from non-work areas and selecting appropriate personal protective equipment and tools,constructing a containment area so that all dust or debris generated by the work remains within the protected area, and using tools that minimize dust and heat(<212°F). For additional information, refer to Part 2.3.3 of the CGP Fact Sheet. 7.2.1.4 Turbidity Benchmark Monitoring for Sites Discharging Dewatering Water to Protect the Water Quality of Sensitive Waters For sites discharging dewatering water to"sensitive waters"(i.e., receiving waters listed as impaired for sediment or a sediment-related parameter(as defined in Appendix A, 2022 CGP), or receiving waters designated as a Tier 2,Tier 2.5,or Tier 3 for antidegradation purposes)you are required to comply with the benchmark monitoring requirements in this Part and document the procedures you will use at your site in your SWPPP pursuant to Part 7.2.8.A summary of these requirements is included in Table 1. EPA notes that the benchmark threshold is not an effluent limitation, rather it is an indicator that the dewatering controls may not be working to protect water quality,which the operator must investigate and correct as appropriate.A benchmark exceedance is not a permit violation. However,if a benchmark exceedance triggers corrective action in Part 5.1.5a,failure to conduct any required action is a permit violation. Where there are multiple operators associated with the same site,the operators may coordinate with one another to carry out the monitoring requirements of this Part in order to avoid duplicating efforts.Such coordinating arrangements must be described in the SWPPP consistent with Part 7.2.8. Regardless of how the operators divide the responsibilities for monitoring and reporting,each operator remains responsible for compliance with these requirements. For instance, if Operator A relies on Operator B to meet the Part 3.3.1 turbidity monitoring requirements,the Part 3.3.4 reporting and recordkeeping requirements,and the Part 5.2.2 corrective action provisions when applicable,Operator A does not have to duplicate these same 72 Turbidity Benchmark Monitoring for Dewatering Discharges ............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................ functions if Operator B is implementing them for both operators to be in compliance with the permit. However, Operator A remains responsible for complying with these permit requirements if Operator B fails to take actions that were necessary for Operator A to comply with the permit.See also footnote 83. EPA notes that both Operator A and B are required to submit turbidity monitoring reports as required under Part 3.3.4, however, Operator A's report does not need to include the data collected by Operator B as long as Operator B submits the required data and Operator A's report indicates that it is relying on Operator B to report the data.See Part 3.3.4a. 7.2.1.5 Turbidity monitoring requirements Operators may find it useful to consult EPA's Monitoring and Inspection Guide for Construction Dewatering, available at https://www.epa.gov/npdes/construction-general-permit-resources-tools-and-templates,which provides guidelines on how to correctly monitor for turbidity,determine if the weekly average exceeds the benchmark,and, if so, how to proceed with corrective action. Sampling frequency.You must collect at least one turbidity sample from your dewatering discharge each day a discharge occurs. Sampling location.Samples must be taken at all points where dewatering water is discharged.Samples must be taken after the dewatering water has been treated by installed treatment devices pursuant to Parts 2.4.1 and 2.4.3 and prior to its discharge off site into a receiving water,constructed or natural site drainage feature,or storm drain inlet. Representative samples.Samples taken must be representative of the dewatering discharge for any given day as required in Appendix G (standard permit conditions), Part G.10.2. Test methods.Samples must be measured using a turbidity meter that reports results in nephelometric turbidity units(NTUs)and conforms with a Part 136-approved method (e.g., methods 180.1 and 2130).You are required to use the meter,and conduct a calibration verification prior to each day's use,consistent with the manufacturer's instructions. 7.2.1.6 Turbidity benchmark The benchmark threshold for turbidity for this permit is 50 NTUs(referred to elsewhere in this permit as the "standard 50 NTU benchmark") unless EPA has authorized the use of an alternate benchmark in accordance with Part 3.3.2b. Request for alternate benchmark threshold At any time prior to or during your coverage under this permit,you may request that EPA approve a benchmark for your site that is higher than 50 NTUs if you have information demonstrating the higher number is the same as your receiving water's water quality standard for turbidity. Unless EPA approves an alternate benchmark,you will be required to use the standard 50 NTU benchmark.To request approval of an alternate benchmark,you must submit the following information to your applicable EPA Regional Office(see Appendix K): (a)The current turbidity water quality standard that applies to your receiving water and the source/citation. For instance, if your site is located in Washington, DC,and you are discharging to a Class B water,for which the water quality standard is that turbidity may not increase above ambient levels by 73 Turbidity Benchmark Monitoring for Dewatering Discharges ............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................ more than 20 percent,you would reference"Water Quality Standards for the District of Columbia,Chapter 11, Section 1104.8.If (b) If the applicable turbidity water quality standard requires information on natural or background turbidity levels(e.g., "no more than 10 NTU above natural turbidity levels")to determine the specific standard for the receiving water, include available data that can be used to establish the natural turbidity levels of your receiving water(including literature studies or Federal,State,Tribal,or local government data). Data must be representative of the natural turbidity levels of your specific receiving water. Identify the source(s)of all data provided, including if the data are from samples you collected of the receiving water. EPA will inform you of its decision on whether to approve the requested alternate benchmark within 30 days.EPA may approve your request,request additional time(e.g.,if additional information is needed to substantiate the data you provided),or deny your request.Unless and until EPA approves your request to use an alternate benchmark,you are required to use the standard benchmark of 50 NTUs and take any required corrective actions if an exceedance occurs. 7.2.1.7 Comparison of turbidity samples to benchmark Compare the weekly average of your turbidity monitoring results to the standard 50 NTU benchmark,or alternate benchmark if approved by EPA.A"weekly average"is defined as the sum of all of the turbidity samples taken during a "monitoring week"divided by the number of samples measured during that week.Average values should be calculated to the nearest whole number. If the weekly average of your turbidity monitoring results exceeds the standard benchmark(or your approved alternate benchmark),you are required to conduct follow-up corrective action in accordance with Part 5.2.2 and document any corrective action taken in your corrective action log in accordance with Part 5.4. For averaging purposes,a "monitoring week"starts with a Monday and ends on Sunday.Once a new monitoring week starts,you will need to calculate a new average for that week of turbidity monitoring results.64 A weekly average may consist of one or more turbidity monitoring results.64 For example, if turbidity samples from your dewatering discharge in week 1 result in values of 30 NTU on Tuesday,40 NTU on Wednesday,and 45 NTU on Thursday,your weekly average turbidity value would be 38.33 NTU ((30+40+45) 3 = 38 NTU).If in week 2,your turbidity samples resulted in values of 45 NTU on Monday, 30 NTU on Tuesday, 25 NTU on Wednesday,and 15 NTU on Thursday,you would calculate a new average for that week,which would yield an average turbidity value of 28.75 NTU ((45+30+25+15) = 4 = 29 NTU). By comparison, if your samples on consecutive days from Friday to Monday were 60 NTU,45 NTU,40 NTU,and 43 NTU, respectively, and there are no other dewatering discharges for the remainder of the week,you would calculate one weekly average for the Friday to Sunday to be 48 NTU ((60+45+40) = 3 = 48 NTU),and a separate weekly average for the one Monday to be 43 NTU (43 = 1 =43 NTU). Although you are not required to collect and analyze more than one turbidity sample per day from your dewatering discharge, if you do collect and analyze more than one sample on any given day,you must include any additional results in the calculation of your weekly average(i.e.,add all individual results for that monitoring week and divide by the total number of samples). For example, if during a monitoring week you take two turbidity samples on Tuesday with a value of 30 NTU and 35 NTU,three samples on Wednesday with a value of 40 NTU,45 NTU, and 48 74 Turbidity Benchmark Monitoring for Dewatering Discharges ormwa er P b-tion Prevention Phan( W::1R,,,1)I anuA ............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................ NTU,and one sample on Thursday with a value of 45 NTU,your weekly average turbidity value for this week would be 41 NTU ((30+35+40+45+48+45) = 6 =41 NTU). If you are conducting turbidity monitoring for more than one dewatering discharge point,you must calculate a weekly average turbidity value for each discharge point and compare each to the turbidity benchmark. 7.2.1.8 Reporting and recordkeeping You must submit reports of your weekly average turbidity data to EPA no later than 30 days following the end of each monitoring quarter. If there are monitoring weeks in which there was no dewatering discharge,or if there is a monitoring quarter with no dewatering discharge, indicate this in your turbidity monitoring report.If another operator associated with your same site is conducting turbidity monitoring on your behalf pursuant to Part 3.3, indicate this in your turbidity monitoring report. For the purposes of this permit,the following monitoring quarters and reporting deadlines apply: Table 59.

If the EPA Regional Office grants you approval to use a paper turbidity monitoring report form,and you elect to use it,you must complete the form in Appendix K. If EPA approves of your request to use an alternate turbidity benchmark pursuant to Part 3.3.2b, EPA will substitute the alternate benchmark in your NeT account For each day in which you are required to monitor,you must record the monitoring information required by Appendix G, Parts G.10.2 and G.10.3 and retain all such information for a period of at least three years from the date this permit expires or from the date your authorization is terminated.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential)when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential)when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

For the purposes of this permit and in the context of stormwater discharges associated with construction activity, an "operator" is any party associated with a construction project that meets either of the following two criteria: a. The party has operational control over construction plans and specifications, including the ability to make modifications to those plans and specifications; or b. The party has day-to-day operational control of those activities at a project that are necessary to ensure compliance with the permit conditions. Where there are multiple operators associated with the same project, all operators must obtain permit coverage.' Subcontractors generally are not considered operators for the purposes of this permit. 1.1.2 Your site's construction activities: a. Will disturb one or more acres of land, or will disturb less than one acre of land but are part of a common plan of development or sale (as defined in Appendix A) that will ultimately disturb one or more acres of land; or b. Have been designated by EPA as needing permit coverage under 40 CFR § 122.26(a)(1)(v) or 40 CFR § 122.26(b)(15)(ii); 1.1.3 Your site is located in an area where EPA is the permitting authority and where coverage under this permit is available (see Appendix B); 1.1.4 Discharges from your site are not: a. Already covered by a different NPDES permit for the same discharge; or b. In the process of having coverage under a different NPDES permit for the same discharge denied, terminated, or revoked.2, 3 1.1.5 You can demonstrate you meet one of the criteria in the Endangered Species Protection section of the Notice of Intent (NOI) that you submit for coverage under this permit, per Part 1.4, with respect to the protection of Federally listed endangered or threatened species and Federally designated critical habitat under the Endangered Species Act If the operator of a "construction support activity" (see Part 1.2.1 c) is different than the operator of the main site,that operator must also obtain permit coverage.See Part 7.1 for clarification on the sharing of permit-related functions between and among operators on the same site and for conditions that apply to developing a SWPPP for multiple operators associated with the same site. 2 Parts 1.1.4a and 1.1.4b do not include sites currently covered under the 2017 CGP that are in the process of obtaining coverage under this permit, nor sites covered under this permit that are transferring coverage to a different operator. 3 Notwithstanding a site being made ineligible for coverage under this permit because it falls under the description of Parts 1.1.4a or 1.1.4b, above, EPA may waive the applicable eligibility requirement after specific review if it determines that coverage under this permit is appropriate. Page 1 2022 Construction General Permit (CGP) (ESA). If the EPA Regional Office grants you a waiver from electronic reporting per Part 1.4.2, you must complete the ESA worksheet in Appendix D to demonstrate you meet one of the criteria and submit it with your paper NOI (Appendix 1). 1.1.6 You have completed the screening process in Appendix E relating to the protection of historic properties; and 1.1.7 You have complied with all requirements in Part 9 imposed by the applicable State, Indian Tribe, or Territory in which your construction activities and/or discharge will occur. 1.1.8 For "new sources" (as defined in Appendix A) only: a. EPA has not, prior to authorization under this permit, determined that discharges from your site will not meet applicable water quality standards. Where such a determination is made prior to authorization, EPA may notify you that an individual permit application is necessary. However, EPA may authorize your coverage under this permit after you have included appropriate controls and implementation procedures designed to bring your discharge into compliance with this permit, specifically the requirement to meet water quality standards. In the absence of information demonstrating otherwise, EPA expects that compliance with the requirements of this permit, including the requirements applicable to such discharges in Part 3, will result in discharges that meet applicable water quality standards. b. Discharges from your site to a Tier 2, Tier 2.5, or Tier 3 water4 will not lower the water quality of the applicable water. In the absence of information demonstrating otherwise, EPA expects that compliance with the requirements of this permit, including the requirements applicable to such discharges in Part 3.2,will result in discharges that will not lower the water quality of such waters. 1.1.9 If you plan to add "cationic treatment chemicals" (as defined in Appendix A) to stormwater and/or authorized non-stormwater prior to discharge, you may not submit your NOI until you notify your applicable EPA Regional Office (see Appendix J) in advance and the EPA Regional Office authorizes coverage under this permit after you have included appropriate controls and implementation procedures designed to ensure that your use of cationic treatment chemicals will result in discharges that meet applicable water quality standards. 4 Note:Your site will be considered to discharge to a Tier 2,Tier 2.5, or Tier 3 water if the first receiving water to which you discharge is identified by a State,Tribe, or EPA as a Tier 2,Tier 2.5, or Tier 3 water. For discharges that enter a storm sewer system prior to discharge,the first receiving water to which you discharge is the waterbody that receives the stormwater discharge from the storm sewer system.The current list of Tier 2,Tier 2.5,and Tier 3 waters located in the areas eligible for coverage under this permit can be found at,Ih1;;i;„I s: . a. ov in des conslirucliiOn eneirall irir iil iresouirces 1.0olls and lei Ila.l. s.

Water used to wash vehicles and equipment, provided that there is no discharge of soaps, solvents, or detergents used for such purposes; e. Water used to control dust; f. Potable water including uncontaminated water line flushings; 5 See "Discharge" as defined in Appendix A. Note:Any discharges not expressly authorized in this permit cannot become authorized or shielded from liability under CWA Section 402(k) by disclosure to EPA,State, or local authorities after issuance of this permit via any means, including the Notice of Intent (NOI) to be covered by the permit, the SWPPP, or during an inspection. Page 3 2022 Construction General Permit (CGP) g. External building washdown, provided soaps, solvents, and detergents are not used, and external surfaces do not contain hazardous substances (as defined in Appendix A) (e.g., paint or caulk containing polychlorinated biphenyls (PCBs)); h. Pavement wash waters, provided spills or leaks of toxic or hazardous substances have not occurred (unless all spill material has been removed) and where soaps, solvents, and detergents are not used. You are prohibited from directing pavement wash waters directly into any receiving water, storm drain inlet, or constructed or natural site drainage features, unless the feature is connected to a sediment basin, sediment trap, or similarly effective control; L Uncontaminated air conditioning or compressor condensate; j. Uncontaminated, non-turbid discharges of ground water or spring water; k. Foundation or footing drains where flows are not contaminated with process materials such as solvents or contaminated ground water; and I. Uncontaminated construction dewatering water6 discharged in accordance with Part 2.4. 1.2.3 Also authorized under this permit are discharges of stormwater listed above in Part 1.2.1, or authorized non-stormwater discharges listed above in Part 1.2.2, commingled with a discharge authorized by a different NPDES permit and/or a discharge that does not require NPDES permit authorization. 1.3 PROHIBITED DISCHARGES? The discharges listed in this Part are prohibited outright or authorized only under the identified conditions.To prevent the discharges in Parts 1.3.1 through 1.3.5, operators must comply with the applicable pollution prevention requirements in Part 2.3 or ensure the discharge is authorized by another NPDES permit consistent with Part 1.2.3 for commingled discharges. 1.3.1 Wastewater from washout of concrete, unless managed by an appropriate control as described in Part 2.3.4; 1.3.2 Wastewater from washout and/or cleanout of stucco, paint, form release oils, curing compounds, and other construction materials; 1.3.3 Fuels, oils, or other pollutants used in vehicle and equipment operation and maintenance; 1.3.4 Soaps, solvents, or detergents used in vehicle and equipment washing or external building washdown; and 1.3.5 Toxic or hazardous substances from a spill or other release. 6 EPA notes that operators may need to comply with additional procedures to verify that the dewatering discharge is uncontaminated. Operators should review Part 9 to determine if any of these requirements apply to their discharge and should ensure that they have complied with any State,Tribal, or local dewatering requirements that apply. 7 EPA includes these prohibited non-stormwater discharges here as a reminder to the operator that the only non-stormwater discharges authorized by this permit are at Part 1.2.2.Any unauthorized non-stormwater discharges must be covered under an individual permit or alternative general permit. Page 4 2022 Construction General Permit (CGP) 1.4 SUBMITTING YOUR NOTICE OF INTENT(NOI) All "operators" (as defined in Appendix A) associated with your construction site who meet the Part 1.1 eligibility conditions, and who seek coverage under this permit, must submit to EPA a complete and accurate NOI in accordance with the deadlines in Table 1 prior to commencement of construction activities (as defined in Appendix A). Exception: If you are conducting construction activities in response to a public emergency (e.g., mud slides, earthquake, extreme flooding conditions, widespread disruption in essential public services), and the related work requires immediate authorization to avoid imminent endangerment to human health, public safety, or the environment, or to reestablish essential public services, you may discharge on the condition that a complete and accurate NOI is submitted within 30 calendar days after commencing construction activities (see Table 1) establishing that you are eligible for coverage under this permit. You must also provide documentation in your Stormwater Pollution Prevention Plan (SWPPP) to substantiate the occurrence of the public emergency pursuant to Part 7.2.3i. 1.4.1 Prerequisite for Submitting Your NOI You must develop a SWPPP consistent with Part 7 before submitting your NOI for coverage under this permit. 1.4.2 How to Submit Your NOI You must use EPA's NPDES eReporting Tool (NeT) to electronically prepare and submit your NOI for coverage under the 2022 CGP unless you received a waiver from your applicable EPA Regional Office. To access NeT, go to„.t s: c x. . o c x. Waivers from electronic reporting may be granted based on one of the following conditions: a. If your operational headquarters is physically located in a geographic area (i.e., ZIP code or census tract) that is identified as under-served for broadband Internet access in the most recent report from the Federal Communications Commission; or b. If you have limitations regarding available computer access or computer capability. If the EPA Regional Office grants you approval to use a paper NOI, and you elect to use it, you must complete the form in Appendix H. 1.4.3 Deadlines for Submitting Your NOI and Your Official Date of Permit Coverage Table 1 provides the deadlines for submitting your NOI and the official start date of your permit coverage,which differ depending on when you commence construction activities. Page 5 2022 Construction General Permit (CGP) Table 1 NOI Submittal Deadlines and Official Start Date for Permit Coverage Type of Operator NOI Submittal Deadline$ Permit Authorization Date9 Operator of a new site (i.e., a site At least 14 calendar days before 14 calendar days after EPA where construction activities commencing construction notifies you that it has commence on or after February 17, activities. received a complete NOI, 2022) unless EPA notifies you that your authorization is delayed or denied. Operator of an existing site (i.e.,a site No later than May 18,2022. 14 calendar days after EPA with 2017 CGP coverage where notifies you that it has construction activities commenced received a complete NOI, prior to February 17,2022) unless EPA notifies you that your authorization is delayed or denied. Provided you submit your NOI no later than May 18,2022, your authorization under the 2017 CGP is automatically continued until you have been granted coverage under this permit or an alternative NPDES permit, or coverage is otherwise terminated. New operator of a permitted site (i.e., At least 14 calendar days before 14 calendar days after EPA an operator that through transfer of the date the transfer to the new notifies you that it has ownership and/or operation replaces operator will take place. received a complete NOI, the operator of an already permitted unless EPA notifies you that construction site that is either a "new your authorization is delayed site" or an "existing site") or denied. Operator of an "emergency-related No later than 30 calendar days You are considered project" (i.e., a project initiated in after commencing construction provisionally covered under response to a public emergency activities. the terms and conditions of (e.g., mud slides,earthquake, this permit immediately, and extreme flooding conditions, fully covered 14 calendar disruption in essential public services), days after EPA notifies you for which the related work requires that it has received a immediate authorization to avoid complete NOI, unless EPA imminent endangerment to human notifies you that your health or the environment,or to authorization is delayed or reestablish essential public services) denied. 8 If you miss the deadline to submit your NOI, any and all discharges from your construction activities will continue to be unauthorized under the CWA until they are covered by this or a different NPDES permit. EPA may take enforcement action for any unpermitted discharges that occur between the commencement of construction activities and discharge authorization. 9 Discharges are not authorized if your NOI is incomplete or inaccurate or if you are not eligible for permit coverage. Page 6 2022 Construction General Permit (CGP) 1.4.4 Modifying your NOI If after submitting your NOI you need to correct or update any fields, you may do so by submitting a "Change NOI" form using NeT. Waivers from electronic reporting may be granted as specified in Part 1.4.2. If the EPA Regional Office has granted you approval to submit a paper NOI modification, you may indicate any NOI changes on the same NOI form in Appendix H. When there is a change to the site's operator, the new operator must submit a new NOI, and the previous operator must submit a Notice of Termination (NOT) form as specified in Part 8.3. The following modifications to an NOI form will result in a 14-day review process: • Changes to the name of the operator; • Changes to the project or site name; • Changes to the estimated area to be disturbed; • Changes to the name of the receiving water10, or additions to the applicable receiving waters; • Changes to eligibility information related to endangered species protection or historic preservation; • Changes to information provided related to the use of chemical treatment at your site; and • Changes to answers provided regarding the demolition of structures over 10,000 square feet of floor space built or renovated before January 1, 1980. During the 14-day review process, you may continue to operate based on the information provided in your original NOI, but you must wait until the review period has ended before you may commence or continue activities on any portion of your site that would be affected by any of the above modifications, unless EPA notifies you that the authorization is delayed or denied. 1.4.5 Your Official End Date of Permit Coverage Once covered under this permit, your coverage will last until the date that: a. You terminate permit coverage consistent with Part 8; or b. You receive permit coverage under a different NPDES permit or a reissued or replacement version of this permit after expiring on February 16, 2027; or c. You fail to submit an NOI for coverage under a reissued or replacement version of this permit before the deadline for existing construction sites where construction activities continue after this permit has expired. 1.5 REQUIREMENT TO POST A NOTICE OF YOUR PERMIT COVERAGE You must post a sign or other notice of your permit coverage at a safe, publicly accessible location in close proximity to the construction site. The notice must be located so it is visible from the public road that is nearest to the active part of the construction 10 As defined in Appendix A,a "receiving water" is "a "Water of the United States" as defined in 40 CFR §122.2 into which the regulated stormwater discharges. Page 7 2022 Construction General Permit (CGP) site, and it must use a font large enough to be readily viewed from a public right-of- way.11 At a minimum, the notice must include: a. The NPDES ID (i.e., permit tracking number assigned to your NOI and the EPA webpage where a copy of the NOI can be found . . . ; b. A contact name and phone number for obtaining additional construction site information; c. The Uniform Resource Locator (URL) for the SWPPP (if available), or the following statement: "If you would like to obtain a copy of the Stormwater Pollution Prevention Plan (SWPPP) for this site, contact the EPA Regional Office at [include the appropriate CGP Regional Office contact information found at 1;" and d. The following statement "If you observe indicators of stormwater pollutants in the discharge or in the receiving water, contact the EPA through the following website: n,.I.. i ,.I..ii ns." 2 TECHNOLOGY-BASED EFFLUENT LIMITATIONS You must comply with the following technology-based effluent limitations in this Part for all authorized discharges.12 2.1 GENERAL STORMWATER CONTROL DESIGN.. INSTALLATION.. AND MAINTENANCE REQUIREMENTS You must design, install, and maintain stormwater controls required in Parts 2.2, 2.3, and 2.4 to minimize the discharge of pollutants in stormwater from construction activities.13To meet this requirement, you must: 2.1.1 Account for the following factors in designing your stormwater controls: a. The expected amount, frequency, intensity, and duration of precipitation;14 b. The nature of stormwater runoff (i.e., flow) and run-on at the site, including factors such as expected flow from impervious surfaces, slopes, and site drainage features. You must design stormwater controls to control stormwater volume, velocity, and peak flow rates to minimize discharges of pollutants in stormwater and to minimize channel and streambank erosion and scour in the immediate vicinity of discharge points; and c. The soil type and range of soil particle sizes expected to be present on the site. >> If the active part of the construction site is not visible from a public road, then place the notice of permit coverage in a position that is visible from the nearest public road and as close as possible to the construction site. 12 For each of the effluent limits in Part 2, as applicable to your site,you must include in your SWPPP (1) a description of the specific control(s) to be implemented to meet the effluent limit; (2) any applicable design specifications; (3) routine maintenance specifications; and (4) the projected schedule for installation/implementation.See Part 7.2.6. 13 The permit does not recommend or endorse specific products or vendors. 14 Stormwater controls must be designed using the most recent data available to account for recent precipitation patterns and trends. Page 8 2022 Construction General Permit (CGP) If your site is exposed to or has previously experienced major storms, such as hurricanes, storm surge, extreme/heavy precipitation, and flood events, you should also include consideration of and contingencies for whether implementing structural improvements, enhanced/resilient stormwater controls, and other mitigation measures may help minimize impacts from stormwater discharges from such major storm events. 2.1.2 Design and install all stormwater controls in accordance with good engineering practices, including applicable design specifications.15 2.1.3 Complete installation of stormwater controls by the time each phase of construction activities has begun. a. By the time construction activity in any given portion of the site begins, install and make operational any downgradient sediment controls (e.g., buffers, perimeter controls, exit point controls, storm drain inlet protection) that control discharges from the initial site clearing, grading, excavating, and other earth-disturbing activities.16 b. Following the installation of these initial controls, install and make operational all stormwater controls needed to control discharges prior to subsequent earth- disturbing activities. 2.1.4 Ensure all stormwater controls are maintained and remain in effective operating condition during permit coverage and are protected from activities that would reduce their effectiveness. a. Comply with any specific maintenance requirements for the stormwater controls listed in this permit, as well as any recommended by the manufacturer.17 b. If at any time you find that a stormwater control needs routine maintenance (i.e., minor repairs or other upkeep performed to ensure the site's stormwater controls remain in effective operating condition, not including significant repairs or the need to install a new or replacement control), you must immediately initiate the needed work, and complete such work by the close of the next business day. If it is infeasible to complete the routine maintenance by the close of the next business day, you must document why this is the case and why the repair or other upkeep to be performed should still be considered routine maintenance in your inspection report under Part 4.7.1 c and complete such work no later than seven (7) calendar days from the time of discovery of the condition requiring maintenance. c. If you must repeatedly (i.e., three (3) or more times) make the same routine maintenance fixes to the same control at the same location, even if the fix can be completed by the close of the next business day, you must either: i. Complete work to fix any subsequent repeat occurrences of this same problem under the corrective action procedures in Part 5, including keeping any records 15 Design specifications may be found in manufacturer specifications and/or in applicable erosion and sediment control manuals or ordinances.Any departures from such specifications must reflect good engineering practices and must be explained in your SWPPP.You must also comply with any additional design and installation requirements specified for the effluent limits in Parts 2.2,2.3, and 2.4. 16 Note that the requirement to install stormwater controls prior to each phase of construction activities for the site does not apply to the earth disturbance associated with the actual installation of these controls. Operators should take all reasonable actions to minimize the discharges of pollutants during the installation of stormwater controls. 17 Any departures from such maintenance recommendations made by the manufacturer must reflect good engineering practices and must be explained in your SWPPP. Page 9 2022 Construction General Permit (CGP) of the condition and how it was corrected under Part 5.4; or ii. Document in your inspection report under Part 4.7.1 c why the specific reoccurrence of this same problem should still be addressed as a routine maintenance fix under this Part.18 d. If at any time you find that a stormwater control needs a significant repair or that a new or replacement control is needed, you must comply with the corrective action deadlines for completing such work in in Part 5.2.1 c. 2.2 EROSION AND SEDIMENT CONTROL REQUIREMENTS You must implement erosion and sediment controls in accordance with the following requirements to minimize the discharge of pollutants in stormwater from construction activities. 2.2.1 Provide and maintain natural buffers and/or equivalent erosion and sediment controls for discharges to any receiving waters that is located within 50 feet of the site's earth disturbances. a. Compliance Alternatives. For any discharges to receiving waters located within 50 feet of your site's earth disturbances, you must comply with one of the following alternatives: i. Provide and maintain a 50-foot undisturbed natural buffer; or ii. Provide and maintain an undisturbed natural buffer that is less than 50 feet and is supplemented by erosion and sediment controls that achieve, in combination, the sediment load reduction equivalent to a 50-foot undisturbed natural buffer; or HE, If infeasible to provide and maintain an undisturbed natural buffer of any size, implement erosion and sediment controls to achieve the sediment load reduction equivalent to a 50-foot undisturbed natural buffer. See Appendix F, Part F.2 for additional conditions applicable to each compliance alternative. b. Exceptions. See Appendix F, Part F.2 for exceptions to the compliance alternatives. 2.2.2 Direct stormwater to vegetated areas and maximize stormwater infiltration and filtering to reduce pollutant discharges, unless infiltration would be inadvisable due to the underlying geology(e.g., karst topography) and ground water contamination concerns, or infeasible due to site conditions.19 18 Such documentation could include,for example, that minor repairs completed within the required timeframe are all that is necessary to ensure that the stormwater control continues to operate as designed and installed and that the stormwater control remains appropriate for the flow reaching it. 19 Operators should consider whether factors such as specific contaminant concerns from the construction site,the underlying soils or geology, hydrology, depth to the ground water table, or proximity to source water or wellhead protection area(s) make the site unsuitable for infiltrating construction stormwater.Site conditions that may be of particular concern include proximity to: a current or future drinking water aquifer; a drinking water well or spring (including private/household wells); highly conductive geology such as karst; known pollutant hot spots, such as hazardous waste sites, landfills, gas stations, brownfields; an on- site sewage system or underground storage tank; or soils that do not allow for infiltration. Operators may find it helpful to consult EPA's IDrii.inkiiir aleir a iin Iliacaliion Io I irolecl SOuirce aleirs ID IDS . DWMAPS is an online mapping tool that can be used to locate drinking water providers, potential sources of contamination, polluted waterways, and information on protection initiatives in the site area. Page 10 2022 Construction General Permit (CGP) 2.2.3 Install sediment controls along any perimeter areas of the site that are downslope from any exposed soil or other disturbed areas.20 a. The perimeter control must be installed upgradient of any natural buffers established under Part 2.2.1, unless the control is being implemented pursuant to Part 2.2.1 a.ii-iii; b. To prevent stormwater from circumventing the edge of the perimeter control, install the perimeter control on the contour of the slope and extend both ends of the control up slope (e.g., at 45 degrees) forming a crescent rather than a straight line; c. After installation, to ensure that perimeter controls continue to work effectively: i. Remove sediment before it has accumulated to one-half of the above-ground height of any perimeter control; and ii. After a storm event, if there is evidence of stormwater circumventing or undercutting the perimeter control, extend controls and/or repair undercut areas to fix the problem. d. Exception. For areas at "linear construction sites" (as defined in Appendix A) where perimeter controls are infeasible (e.g., due to a limited or restricted right-of-way), implement other practices as necessary to minimize pollutant discharges to perimeter areas of the site. 2.2.4 Minimize sediment track-out. a. Restrict vehicle use to properly designated exit points; b. Use appropriate stabilization techniques21 at all points that exit onto paved roads; i. Exception: Stabilization is not required for exit points at linear utility construction sites that are used only episodically and for very short durations over the life of the project, provided other exit point controls22 are implemented to minimize sediment track-out; c. Implement additional track-out controls23 as necessary to ensure that sediment removal occurs prior to vehicle exit; and d. Where sediment has been tracked-out from your site onto paved roads, sidewalks, or other paved areas outside of your site, remove the deposited sediment by the end of the same business day in which the track-out occurs or by the end of the next business day if track-out occurs on a non-business day. Remove the track-out by sweeping, shoveling, or vacuuming these surfaces, or by using other similarly effective means of sediment removal. You are prohibited from hosing or sweeping tracked-out 20 Examples of perimeter controls include filter berms; different types of silt fence such as wire-backed silt fence,super silt fence, or multi-layer geotextile silt fence; compost filter socks; gravel barriers; and temporary diversion dikes. 21 Examples of appropriate stabilization techniques include the use of aggregate stone with an underlying geotextile or non-woven filter fabric, and turf mats. 22 Examples of other exit point controls include preventing the use of exit points during wet periods; minimizing exit point use by keeping vehicles on site to the extent possible; limiting exit point size to the width needed for vehicle and equipment usage; using scarifying and compaction techniques on the soil; and avoiding establishing exit points in environmentally sensitive areas (e.g., karst areas;steep slopes). 23 Examples of additional track-out controls include the use of wheel washing, rumble strips, and rattle plates. Page 1 1 2022 Construction General Permit (CGP) sediment into any constructed or natural site drainage feature, storm drain inlet, or receiving water.24 2.2.5 Manage stockpiles or land clearing debris piles composed, in whole or in part, of sediment and/or soi1:25 a. Locate the piles outside of any natural buffers established under Part 2.2.1 and away from any constructed or natural site drainage features, storm drain inlets, and areas where stormwater flow is concentrated; b. Install a sediment barrier along all downgradient perimeter areas of stockpiled soil or land clearing debris piles;26 c. For piles that will be unused for 14 or more days, provide cover27 or appropriate temporary stabilization (consistent with Part 2.2.14); d. You are prohibited from hosing down or sweeping soil or sediment accumulated on pavement or other impervious surfaces into any constructed or natural site drainage feature, storm drain inlet, or receiving water. 2.2.6 Minimize dust. On areas of exposed soil, minimize dust through the appropriate application of water or other dust suppression techniques to control the generation of pollutants that could be discharged in stormwater from the site. 2.2.7 Minimize steep slope disturbances. Minimize the disturbance of "steep slopes" (as defined in Appendix A).28 2.2.8 Preserve native topsoil, unless infeasible.29 2.2.9 Minimize soil compaction.30 In areas of your site where final vegetative stabilization will occur or where infiltration practices will be installed: 24 Fine grains that remain visible (e.g.,staining) on the surfaces of off-site streets, other paved areas, and sidewalks after you have implemented sediment removal practices are not a violation of Part 2.2.4. 25 The requirements in Part 2.2.5 do not apply to the storage of rock, such as rip rap, landscape rock, pipe bedding gravel, and boulders. Refer to Part 2.3.3a for the requirements that apply to these types of materials. 26 Examples of sediment barriers include berms, dikes,fiber rolls,silt fences, sandbags, gravel bags, or straw bale. 27 Examples of cover include tarps, blown straw and hydroseeding. 28 Where disturbance to steep slopes cannot be avoided, operators should consider implementing controls suitable for steep slope disturbances that are effective at minimizing erosion and sediment discharge (e.g., preservation of existing vegetation, hydraulic mulch, geotextiles and mats, compost blankets, earth dikes or drainage swales, terraces,velocity dissipation devices).To identify slopes and soil types that are of comparatively higher risk for sediment discharge in areas of the country where the CGP is in effect, operators can use the tables in Appendix F (see Tables F-2 thru F-6). 29 Stockpiling topsoil at off-site locations,or transferring topsoil to other locations,is an example of a practice that is consistent with the requirements in Part 2.2.8. Preserving native topsoil is not required where the intended function of a specific area of the site dictates that the topsoil be disturbed or removed. For example,some sites may be designed to be highly impervious after construction, and therefore little or no vegetation is intended to remain, or may not have space to stockpile native topsoil on site for later use,in which case it may not be feasible to preserve topsoil. 30 Minimizing soil compaction is not required where the intended function of a specific area of the site dictates that it be compacted. Page 12 2022 Construction General Permit (CGP) a. Restrict vehicle and equipment use in these locations to avoid soil compaction; and b. Before seeding or planting areas of exposed soil that have been compacted, use techniques that rehabilitate and condition the soils as necessary to support vegetative growth. 2.2.10 Protect storm drain inlets. a. Install inlet protection measures that remove sediment from discharges prior to entry into any storm drain inlet that carries stormwater from your site to a receiving water, provided you have authority to access the storm drain inlet.31 Inlet protection measures are not required for storm drain inlets that are conveyed to a sediment basin, sediment trap, or similarly effective control; and b. Clean, or remove and replace, the inlet protection measures as sediment accumulates, the filter becomes clogged, and/or performance is compromised. Where there is evidence of sediment accumulation adjacent to the inlet protection measure, remove the deposited sediment by the end of the same business day in which it is found or by the end of the following business day if removal by the same business day is not feasible. 2.2.11 Control stormwater discharges, including both peak flowrates and total stormwater volume, to minimize channel and streambank erosion and scour in the immediate vicinity of discharge points.32 2.2.12 If you install a sediment basin or similar impoundment: a. Situate the basin or impoundment outside of any receiving water. and any natural buffers established under Part 2.2.1; b. Design the basin or impoundment to avoid collecting water from wetlands; c. Design the basin or impoundment to provide storage for either: i. The calculated volume of runoff from a 2-year, 24-hour storm;33 or ii. 3,600 cubic feet per acre drained. d. Utilize outlet structures that withdraw water from the surface of the sediment basin or similar impoundment, unless infeasible;34 e. Use erosion controls and velocity dissipation devices to prevent erosion at inlets and outlets; and 31 Inlet protection measures can be removed in the event of flood conditions or to prevent erosion. 32 Examples of stormwater controls that can be used to comply with this requirement include the use of erosion controls and/or velocity dissipation devices (e.g., check dams,sediment traps),within and along the length of a constructed site drainage feature and at the outfall to slow down stormwater. 33 Operators may refer to Ih�..::1::::1:..p..... ./.................................................a. ..p. ...m.gOv/nldes/c ns,.Liruc,.Lii n,....,geneirall,....,peiririi,.L,....,ireOuirces,....,,.L0011s,....,and,...., „ IIa��I s for guidance on determining the volume of precipitation associated with their site's local 2-year, ....I g g p p Y 24-hour storm event. 34 The circumstances in which it is infeasible to design outlet structures in this manner are rare. Exceptions may include areas with extended cold weather,where using surface outlets may not be feasible during certain time periods (although they must be used during other periods). If you determine that it is infeasible to meet this requirement,you must provide documentation in your SWPPP to support your determination, including the specific conditions or time periods when this exception will apply. Page 13 2022 Construction General Permit (CGP) f. Remove accumulated sediment to maintain at least one-half of the design capacity and conduct all other appropriate maintenance to ensure the basin or impoundment remains in effective operating condition. 2.2.13 If using treatment chemicals (e.g., polymers, flocculants, coagulants): a. Use conventional erosion and sediment controls before and after the application of treatment chemicals. Chemicals may only be applied where treated stormwater is directed to a sediment control (e.g., sediment basin, perimeter control) before discharge. b. Select appropriate treatment chemicals. Chemicals must be appropriately suited to the types of soils likely to be exposed during construction and present in the discharges being treated (i.e., the expected turbidity, pH, and flow rate of stormwater flowing into the chemical treatment system or area). c. Minimize discharge risk from stored chemicals. Store all treatment chemicals in leak- proof containers that are kept under storm-resistant cover and surrounded by secondary containment structures (e.g.,spill berms, dikes, spill containment pallets), or provide equivalent measures designed and maintained to minimize the potential discharge of treatment chemicals in stormwater or by any other means (e.g., storing chemicals in a covered area, having a spill kit available on site and ensuring personnel are available to respond expeditiously in the event of a leak or spill). d. Comply with State/local requirements. Comply with applicable State and local requirements regarding the use of treatment chemicals. e. Use chemicals in accordance with good engineering practices and specifications of the chemical provider/supplier. Use treatment chemicals and chemical treatment systems in accordance with good engineering practices, and with dosing specifications and sediment removal design specifications provided by the provider/supplier of the applicable chemicals, or document in your SWPPP specific departures from these specifications and how they reflect good engineering practice. f. Ensure proper training. Ensure all persons who handle and use treatment chemicals at the construction site are provided with appropriate, product-specific training prior to beginning application of treatment chemicals. Among other things, the training must cover proper dosing requirements. g. Perform additional measures specified by the EPA Regional Office for the authorized use of cationic chemicals. If you have been authorized to use cationic chemicals at your site pursuant to Part 1.1.9, you must perform all additional measures as conditioned by your authorization to ensure the use of such chemicals will not result in discharges that do not meet water quality standards. 2.2.14 Stabilize exposed portions of the site. Implement and maintain stabilization measures (e.g., seeding protected by erosion controls until vegetation is established,35 sodding, mulching, erosion control blankets, hydromulch, gravel) that minimize erosion from any areas of exposed soil on the site in accordance with Part. 35 If you will be evaluating the use of some type of erosion control netting to the site as part of your site stabilization, EPA encourages you to consider employing products that have been shown to minimize Page 14 2022 Construction General Permit (CGP) a. Stabilization Deadlines:36 Table 2 Deadlines for Initiating and Completing Site Stabilization. Total Amount of Land Disturbance Deadline Occurring At Any One Time37 i. Five acres or less(55.0) Initiate the installation of stabilization measures immediately38 in any areas of exposed soil where Note:this includes sites disturbing more construction activities have permanently ceased or will than five acres(>5.0)total over the be temporarily inactive for 14 or more calendar days;39 course of a project, but that limit and disturbance at any one time ri.e.,phase Complete the installation of stabilization measures as the disturbance) to five acres or less soon as practicable, but no later than 14 calendar days <_5.0 impacts on wildlife. For instance,the U.S. Fish &Wildlife Service provides recommendations on the type of netting practices that are considered "wildlife friendly," including those that use natural fiber or 100 percent biodegradable materials and that use a loose weave with a non-welded, movable jointed netting, as well as those products that are not wildlife friendly including square plastic netting that are degradable (e.g., photodegradable, UV-degradable, oxo-degradable), netting made from polypropylene, nylon, polyethylene, or polyester.Other recommendations include removing the netting product when it is no longer needed.See htl. s: .f s. ov mid esl easlllansiin Iliilbirai df illdlliifel iriieindll IEirosiioin n-.l.irolllPiroduc-.l.'s it viised. df for further information.There also may be State,Tribal, or local requirements about using wildlife friendly erosion control products. 36 EPA may determine, based on an inspection carried out under Part 4.8 and corrective actions required under Part 5.3,that the level of sediment discharge on the site makes it necessary to require a faster schedule for completing stabilization. For instance, if sediment discharges from an area of exposed soil that is required to be stabilized are compromising the performance of existing stormwater controls, EPA may require stabilization to correct this problem. 37 Limiting disturbances to five (5) acres or less at any one time means that at no time during the project do the cumulative earth disturbances exceed five (5) acres.The following examples would qualify as limiting disturbances at any one time to five (5) acres or less: 1. The total area of disturbance for a project is five (5) acres or less. 2. The total area of disturbance for a project will exceed five (5) acres, but the operator ensures that no more than five (5) acres will be disturbed at any one time through implementation of stabilization measures. In this way,site stabilization can be used to "free up" land that can be disturbed without exceeding the five (5)-acre cap to qualify for the 14-day stabilization deadline. For instance,if an operator completes stabilization of two (2) acres of land on a five (5)-acre disturbance,then two (2) additional acres could be disturbed while still qualifying for the longer 14-day stabilization deadline. 38 The following are examples of activities that would constitute the immediate initiation of stabilization: 1. Prepping the soil for vegetative or non-vegetative stabilization as long as seeding, planting, and/or installation of non-vegetative stabilization products takes place as soon as practicable, but no later than one (1) calendar day of completing soil preparation; 2. Applying mulch or other non-vegetative product to the exposed area; 3. Seeding or planting the exposed area; 4. Starting any of the activities in # 1 -3 on a portion of the entire area that will be stabilized; and 5. Finalizing arrangements to have stabilization product fully installed in compliance with the deadlines for completing stabilization. 39 The requirement to initiate stabilization immediately is triggered as soon as you know that construction work on a portion of the site is temporarily ceased and will not resume for 14 or more days, or as soon as you know that construction work is permanently ceased. In the context of this provision, "immediately" means as soon as practicable, but no later than the end of the next business day, following the day when the construction activities have temporarily or permanently ceased. Page 15 2022 Construction General Permit (CGP) Total Amount of Land Disturbance Deadline Occurring At Any One Time37 after stabilization has been initiated.40 ii.More than five acres(>5.0) Initiate the installation of stabilization measures immediately41 in any areas of exposed soil where construction activities have permanently ceased or will be temporarily inactive for 14 or more calendar days;42 and • Complete the installation of stabilization measures as soon as practicable, but no later than seven (7) calendar days after stabilization has been initiated.43 b. Exceptions: i. Arid,semi-arid, and drought-stricken areas (as defined in Appendix A). If it is the seasonally dry period (as defined in Appendix A)44 or a period in which drought is occurring, and vegetative stabilization measures are being used: (a) Immediately initiate and,within 14 calendar days of temporary or permanent cessation of work in any portion of your site, complete the installation of temporary non-vegetative stabilization measures to the extent necessary to prevent erosion; (b) As soon as practicable, given conditions or circumstances on the site, complete all activities necessary to seed or plant the area to be stabilized; and (c) If construction is occurring during the seasonally dry period, indicate in your SWPPP the beginning and ending dates of the seasonally dry period and your site conditions. Also include the schedule you will follow for initiating and completing vegetative stabilization. ii. Unforeseen circumstances. Operators that are affected by unforeseen circumstances45 that delay the initiation and/or completion of vegetative stabilization: 40 If vegetative stabilization measures are being implemented,stabilization is considered "installed"when all activities necessary to seed or plant the area are completed, including the application of any non- vegetative protective cover (e.g., mulch, erosion control blanket), if applicable. If non-vegetative stabilization measures are being implemented,stabilization is considered "installed"when all such measures are implemented or applied. 41 See footnote 38. 42 See footnote 39. 43 See footnote 40. 44 The term "seasonally dry period" as defined in Appendix A refers to a month in which the long-term average total precipitation is less than or equal to 0.5 inches.

Page 16 2022 Construction General Permit (CGP) (a) Immediately initiate and,within 14 calendar days, complete the installation of temporary non-vegetative stabilization measures to prevent erosion; (b) Complete all soil conditioning, seeding,watering or irrigation installation, mulching, and other required activities related to the planting and initial establishment of vegetation as soon as conditions or circumstances allow it on your site; and (c) Document in the SWPPP the circumstances that prevent you from meeting the deadlines in Part 2.2.14a and the schedule you will follow for initiating and completing stabilization. iii. Discharges to a sediment- or nutrient-impaired water or to a water that is identified by your State,Tribe, or EPA as Tier 2,Tier 2.5, or Tier 3 for antidegradation purposes. Complete stabilization as soon as practicable, but no later than seven (7) calendar days after stabilization has been initiated. c. Final Stabilization Criteria (for any areas not covered by permanent structures): i. Establish uniform, perennial vegetation (i.e., evenly distributed, without large bare areas) to provide 70 percent or more of the vegetative cover native to local undisturbed areas; and/or ii. Implement permanent non-vegetative stabilization measures46 to provide effective cover of any areas of exposed soil. HE, Exceptions: (a) Arid,semi-arid, and drought-stricken areas (as defined in Appendix A). Final stabilization is met if the area has been seeded or planted to establish vegetation that provides 70 percent or more of the vegetative cover native to local undisturbed areas within three (3) years and, to the extent necessary to prevent erosion on the seeded or planted area, non-vegetative erosion controls have been applied to provide cover for at least three years without active maintenance. (b) Disturbed areas on agricultural land that are restored to their preconstruction agricultural use. The Part 2.2.14c final stabilization criteria do not apply. (c) Areas that need to remain disturbed. In limited circumstances, stabilization may not be required if the intended function of a specific area of the site necessitates that it remain disturbed, and only the minimum area needed remains disturbed (e.g., dirt access roads, utility pole pads, areas being used for storage of vehicles, equipment, materials). 2.3 POLLUTION PREVENTION REQUIREMENTS47 You must implement pollution prevention controls in accordance with the following requirements to minimize the discharge of pollutants in stormwater and to prevent the discharge of pollutants from spilled or leaked materials from construction activities. 46 Examples of permanent non-vegetative stabilization measures include riprap, gravel, gabions, and geotextiles. 47 Under this permit,you are not required to minimize exposure for any products or materials where the exposure to precipitation and to stormwater will not result in a discharge of pollutants, or where exposure of a specific material or product poses little risk of stormwater contamination (such as final products and materials intended for outdoor use). Page 17 2022 Construction General Permit (CGP) 2.3.1 For equipment and vehicle fueling and maintenance: a. Provide an effective means of eliminating the discharge of spilled or leaked chemicals, including fuels and oils, from these activities;48 b.

Ensure adequate supplies are available at all times to handle spills, leaks, and disposal of used liquids; d. Use drip pans and absorbents under or around leaky vehicles; e. Dispose of or recycle oil and oily wastes in accordance with other Federal, State, Tribal, or local requirements; and f. Clean up spills or contaminated surfaces immediately, using dry clean up measures (do not clean contaminated surfaces by hosing the area down), and eliminate the source of the spill to prevent a discharge or a continuation of an ongoing discharge. 2.3.2 For equipment and vehicle washing: a. Provide an effective means of minimizing the discharge of pollutants from equipment and vehicle washing, wheel wash water, and other types of wash waters;49 b. Ensure there is no discharge of soaps, solvents, or detergents in equipment and vehicle wash water; and c. For storage of soaps, detergents, or solvents, provide either (1) cover (e.g., plastic sheeting, temporary roofs) to minimize the exposure of these detergents to precipitation and to stormwater, or (2) a similarly effective means designed to minimize the discharge of pollutants from these areas. 2.3.3 For storage, handling, and disposal of building products, materials, and wastes:so a. For building materials and building products,51 provide either (1) cover (e.g., plastic sheeting, temporary roofs) to minimize the exposure of these products to 48 Examples of effective means include: • Locating activities away from receiving waters,storm drain inlets, and constructed or natural site drainage feature so that stormwater coming into contact with these activities cannot reach waters of the U.S.; • Providing secondary containment (e.g.,spill berms, dikes, spill containment pallets) and cover where appropriate; and • Having a spill kit available on site and ensuring personnel are available to respond expeditiously in the event of a leak or spill. 49 Examples of effective means include locating activities away from receiving waters and storm drain inlets or constructed or natural site drainage features and directing wash waters to a sediment basin or sediment trap, using filtration devices,such as filter bags or sand filters, or using other similarly effective controls. 50 Compliance with the requirements of this permit does not relieve compliance requirements with respect to Federal,State, or local laws and regulations governing the storage, handling, and disposal of solid, hazardous, or toxic wastes and materials. 51 Examples of building materials and building products typically present at construction sites include asphalt sealants, copper flashing,roofing materials, adhesives, concrete admixtures, and gravel and mulch stockpiles. Page 18 2022 Construction General Permit (CGP) precipitation and to stormwater, or (2) a similarly effective means designed to minimize the discharge of pollutants from these areas. Exception: Minimization of exposure is not required in cases where the exposure to precipitation and to stormwater will not result in a discharge of pollutants, or where exposure of a specific material or product poses little risk of stormwater contamination (such as final products and materials intended for outdoor use). b. For pesticides, herbicides, insecticides, fertilizers, and landscape materials: L In storage areas, provide either (1) cover (e.g., plastic sheeting, temporary roofs) to minimize the exposure of these chemicals to precipitation and to stormwater, or (2) a similarly effective means designed to minimize the discharge of pollutants from these areas; and ii. Comply with all application and disposal requirements included on the registered pesticide, herbicide, insecticide, and fertilizer label (see also Part 2.3.5). c. For diesel fuel, oil, hydraulic fluids, other petroleum products, and other chemicals: The following requirements apply to the storage and handling of chemicals on your site. If you are already implementing controls as part of an SPCC or other spill prevention plan that meet or exceed the requirements of this Part, you may continue to do so and be considered in compliance with these provisions provided you reference the applicable parts of the SPCC or other plans in your SWPPP as required in Part 7.2.6b.viii. L If any chemical container has a storage capacity of less than 55 gallons: (a) The containers must be water-tight, and must be kept closed, sealed, and secured when not being actively used; (b) If stored outside, use a spill containment pallet or similar device to capture small leaks or spills; and (c) Have a spill kit available on site that is in good working condition (i.e., not damaged, expired, or used up) and ensure personnel are available to respond immediately in the event of a leak or spill. ii. If any chemical container has a storage capacity of 55 gallons or more: (a) The containers must be water-tight, and must be kept closed, sealed, and secured when not being actively used; (b) Store containers a minimum of 50 feet from receiving waters, constructed or natural site drainage features, and storm drain inlets. If infeasible due to site constraints, store containers as far away from these features as the site permits. If site constraints prevent you from storing containers 50 feet away from receiving waters or the other features identified, you must document in your SWPPP the specific reasons why the 50-foot setback is infeasible, and how you will store containers as far away as the site permits; (c) Provide either (1) cover (e.g., temporary roofs) to minimize the exposure of these containers to precipitation and to stormwater, or (2) secondary containment (e.g., curbing, spill berms, dikes, spill containment pallets, double-wall, above-ground storage tank); and (d) Have a spill kit available on site that is in good working condition (i.e., not Page 19 2022 Construction General Permit (CGP) damaged, expired, or used up) and ensure personnel are available to respond immediately in the event of a leak or spill. Additional secondary containment measures are listed at 40 CFR § 1 12.7(c)(1). iii. Clean up spills immediately, using dry clean-up methods where possible, and dispose of used materials properly. You are prohibited from hosing the area down to clean surfaces or spills. Eliminate the source of the spill to prevent a discharge or a furtherance of an ongoing discharge. d. For hazardous or toxic wastes:52 L Separate hazardous or toxic waste from construction and domestic waste; ii. Store waste in sealed containers, constructed of suitable materials to prevent leakage and corrosion, and labeled in accordance with applicable Resource Conservation and Recovery Act (RCRA) requirements and all other applicable Federal, State, Tribal, or local requirements; iii. Store all outside containers within appropriately-sized secondary containment (e.g.,spill berms, dikes, spill containment pallets) to prevent spills from being discharged, or provide a similarly effective means designed to prevent the discharge of pollutants from these areas (e.g., storing chemicals in a covered area, having a spill kit available on site); iv. Dispose of hazardous or toxic waste in accordance with the manufacturer's recommended method of disposal and in compliance with Federal, State, Tribal, and local requirements; v. Clean up spills immediately, using dry clean-up methods, and dispose of used materials properly. You are prohibited from hosing the area down to clean surfaces or spills. Eliminate the source of the spill to prevent a discharge or a furtherance of an ongoing discharge; and A. Follow all other Federal, State, Tribal, and local requirements regarding hazardous or toxic waste. e. For construction and domestic wastes:s3 L Provide waste containers (e.g., dumpster, trash receptacle) of sufficient size and number to contain construction and domestic wastes; (a) For waste containers with lids, keep waste container lids closed when not in use, and close lids at the end of the business day and during storm events. For waste containers without lids, provide either (1) cover(e.g., a tarp, plastic sheeting, temporary roof) to minimize exposure of wastes to precipitation, or (2) a similarly effective means designed to minimize the discharge of pollutants (e.g., secondary containment); (b) On business days, clean up and dispose of waste in designated waste 52 Examples of hazardous or toxic waste that may be present at construction sites include paints,caulks, sealants, fluorescent light ballasts,solvents, petroleum-based products,wood preservatives, additives, curing compounds, and acids. 53 Examples of construction and domestic wastes include packaging materials, scrap construction materials, masonry products, timber, pipe and electrical cuttings, plastics, styrofoam, concrete, demolition debris; and other trash or discarded materials. Page 20 2022 Construction General Permit (CGP) containers; and (c) Clean up immediately if containers overflow, and if there is litter elsewhere on the site from escaped trash. ii. Waste containers are not required for the waste remnant or unused portions of construction materials or final products that are covered by the exception in Part 2.2.3a provided that: (a) These wastes are stored separately from other construction or domestic wastes addressed by Part 2.3.3e.i (i.e., wastes not covered by the exception in Part 2.3.3a). If the wastes are mixed, they must be stored in waste containers as required in Part 2.3.3e.i; and (b) These wastes are stored in designated areas of the site, the wastes are described in the SWPPP (see Part 7.2.6b.ix), and identified in the site plan (see Part 7.2.4i). f. For sanitary waste, position portable toilets so they are secure and will not be tipped or knocked over, and are located away from receiving waters, storm drain inlets, and constructed or natural site drainage features. 2.3.4 For washing applicators and containers used for stucco, paint, concrete,form release oils, curing compounds, or other materials: a.

Apply at a rate and in amounts consistent with manufacturer's specifications, or document in the SWPPP departures from the manufacturer specifications where appropriate in accordance with Part 7.2.6b.x; b. Apply at the appropriate time of year for your location, and preferably timed to coincide as closely as possible to the period of maximum vegetation uptake and growth; Page 21 2022 Construction General Permit (CGP) c. Avoid applying before heavy rains that could cause excess nutrients to be discharged; d. Never apply to frozen ground; e. Never apply to constructed or natural site drainage features; and f. Follow all other Federal, State, Tribal, and local requirements regarding fertilizer application. 2.3.6 Emergency Spill Notification Requirements Discharges of toxic or hazardous substances from a spill or other release are prohibited, consistent with Part 1.3.5. Where a leak, spill, or other release containing a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR part 1 10, 40 CFR part 117, or 40 CFR part 302 occurs during a 24-hour period, you must notify the National Response Center (NRC) at (800) 424-8802 or, in the Washington, DC metropolitan area, call (202) 267-2675 in accordance with the requirements of 40 CFR part 1 10, 40 CFR part 1 17, and 40 CFR part 302 as soon as you have knowledge of the release. You must also, within seven (7) calendar days of knowledge of the release, provide a description of the release, the circumstances leading to the release, and the date of the release. State, Tribal, or local requirements may necessitate additional reporting of spills or discharges to local emergency response, public health, or drinking water supply agencies. 2.4 CONSTRUCTION DEWATERING REQUIREMENTS Comply with the following requirements to minimize the discharge of pollutants from dewatering54 operations. 2.4.1 Route dewatering water through a sediment control (e.g., sediment trap or basin, pumped water filter bag) designed to prevent discharges with visual turbidity;55 2.4.2 Do not discharge visible floating solids or foam; 2.4.3 The discharge must not cause the formation of a visible sheen on the water surface, or visible oily deposits on the bottom or shoreline of the receiving water. Use an oil-water separator or suitable filtration device (such as a cartridge filter) designed to remove oil, grease, or other products if dewatering water is found to or expected to contain these materials; 2.4.4 To the extent feasible, use well-vegetated (e.g., grassy or wooded), upland areas of the site to infiltrate dewatering water before discharge.56 You are prohibited from using receiving waters as part of the treatment area; 2.4.5 To prevent dewatering-related erosion and related sediment discharges: a. Use stable, erosion-resistant surfaces (e.g., well-vegetated grassy areas, clean filter stone, geotextile underlayment) to discharge from dewatering controls; 54 "Dewatering" is defined in Appendix A as "the act of draining accumulated stormwater and/or ground water from building foundations,vaults, and trenches, or other similar points of accumulation." 55 For the purposes of this permit, visual turbidity is present where there is a sediment plume in the discharge or the discharge appears cloudy, or opaque, or has a visible contrast that can be identified by an observer. 56 See footnote 19. Page 22 2022 Construction General Permit (CGP) b. Do not place dewatering controls, such as pumped water filter bags, on steep slopes (as defined in Appendix A); and c. At all points where dewatering water is discharged, comply with the velocity dissipation requirements of Part 2.2.11. 2.4.6 For backwash water, either haul it away for disposal or return it to the beginning of the treatment process; 2.4.7 Replace and clean the filter media used in dewatering devices when the pressure differential equals or exceeds the manufacturer's specifications; and 2.4.8 Comply with dewatering-specific inspection requirements in Part 4. 3 WATER QUALITY-BASED EFFLUENT LIMITATIONS 3.1 GENERAL EFFLUENT LIMITATION TO MEET APPLICABLE WATER QUALITY STANDARDS Discharges must be controlled as necessary to meet applicable water quality standards. Discharges must also comply with any additional State or Tribal requirements that are in Part 9. In the absence of information demonstrating otherwise, EPA expects that compliance with the conditions in this permit will result in stormwater discharges being controlled as necessary to meet applicable water quality standards. If at any time you become aware, or EPA determines, that discharges are not being controlled as necessary to meet applicable water quality standards, you must take corrective action as required in Parts 5.1 and 5.2, and document the corrective actions as required in Part 5.4. EPA may insist that you install additional controls (to meet the narrative water quality- based effluent limit above) on a site-specific basis, or require you to obtain coverage under an individual permit, if information in your NOI or from other sources indicates that your discharges are not controlled as necessary to meet applicable water quality standards. This includes situations where additional controls are necessary to comply with a wasteload allocation in an EPA-established or approved TMDL. If during your coverage under a previous permit, you were required to install and maintain stormwater controls specifically to meet the assumptions and requirements of an EPA-approved or established TMDL (for any parameter) or to otherwise control your discharge to meet water quality standards, you must continue to implement such controls as part of your coverage under this permit. 3.2 WATER QUALITY-BASED CONDITIONS FOR SITES DISCHARGING TO CERTAIN IMPAIRED AND HIGH QUALITY RECEIVING WATERS For any portion of the site that discharges to a sediment or nutrient-impaired water or to a water that is identified by your State, Tribe, or EPA as Tier 2, Tier 2.5, or Tier 3 for antidegradation purposes,57 you must comply with the inspection frequency specified in Part 4.3 and you must comply with the stabilization deadline specified in Part 2.2.14b.iii.58 57 Refer to Appendix A for definitions of "impaired water" and "Tier 2," "Tier 2.5," and "Tier 3" waters. For assistance in determining whether your site discharges to impaired waters, EPA has developed a tool that is available at,Ih ::::::..p..s....... m. a. o n des e as sloirir aLeir dii clh�ait inr a iin LoolIs. For assistance in determining whether your site discharges to a Tier 2,2.5, or 3 water, refer to the list of such waters at Ih�ll s� .e a. ov in es c nslirucliion eneirall eirir iil' iresources l.00lls and l.ei Ilai. S. 58 If you qualify for any of the reduced inspection frequencies in Part 4.4,you may conduct inspections in Page 23 2022 Construction General Permit (CGP) If you discharge to a water that is impaired for a parameter other than a sediment- related parameter or nutrients, EPA will inform you if any additional controls are necessary for your discharge to be controlled as necessary to meet water quality standards. These controls might include those necessary for your discharge to be consistent with the assumptions of any available wasteload allocation in any applicable TMDL. In addition, EPA may require you to apply for and obtain coverage under an individual NPDES permit. In addition, on a case-by-case basis, EPA may notify operators of new sites or operators of existing sites with increased discharges that additional analyses, stormwater controls, and/or other measures are necessary to comply with the applicable antidegradation requirements, or notify you that an individual permit application is necessary. If you discharge to a water that is impaired for polychlorinated biphenyls (PCBs) and are engaging in demolition of any structure with at least 10,000 square feet of floor space built or renovated before January 1, 1980, you must: a. Implement controls59 to minimize the exposure of PCB-containing building materials, including paint, caulk, and pre-1980 fluorescent lighting fixtures, to precipitation and to stormwater; and b. Ensure that disposal of such materials is performed in compliance with applicable State, Federal, and local laws. 3.3 TURBIDITY BENCHMARK MONITORING FOR SITES DISCHARGING DEWATERING WATER TO PROTECT THE WATER QUALITY OF SENSITIVE WATERS For sites discharging dewatering water to "sensitive waters" (i.e., receiving waters listed as impaired for sediment or a sediment-related parameter (as defined in Appendix A), or receiving waters designated as a Tier 2, Tier 2.5, or Tier 3 for antidegradation purposes) you are required to comply with the benchmark monitoring requirements in this Part and document the procedures you will use at your site in your SWPPP pursuant to Part 7.2.8. A summary of these requirements is included in Table 1. EPA notes that the benchmark threshold is not an effluent limitation, rather it is an indicator that the dewatering controls may not be working to protect water quality, which the operator must investigate and correct as appropriate. A benchmark exceedance is not a permit violation. However, if a benchmark exceedance triggers corrective action in Part 5.1.5a, failure to conduct any required action is a permit violation. Where there are multiple operators associated with the same site, the operators may coordinate with one another to carry out the monitoring requirements of this Part in order to avoid duplicating efforts. Such coordinating arrangements must be described in the SWPPP consistent with Part 7.2.8. Regardless of how the operators divide the accordance with Part 4.4 for any portion of your site that discharges to a sensitive water. 59 Examples of controls to minimize exposure of PCBs to precipitation and stormwater include separating work areas from non-work areas and selecting appropriate personal protective equipment and tools, constructing a containment area so that all dust or debris generated by the work remains within the protected area, and using tools that minimize dust and heat (<2120F). For additional information, refer to Part 2.3.3 of the CGP Fact Sheet. Page 24 2022 Construction General Permit (CGP) responsibilities for monitoring and reporting, each operator remains responsible for compliance with these requirements.60 3.3.1 Turbidity monitoring requirements61 a. Sampling frequency. You must collect at least one turbidity sample from your dewatering discharge each day a discharge occurs. b. Sampling location. Samples must be taken at all points where dewatering water is discharged. Samples must be taken after the dewatering water has been treated by installed treatment devices pursuant to Parts 2.4.1 and 2.4.3 and prior to its discharge off site into a receiving water, constructed or natural site drainage feature, or storm drain inlet. c. Representative samples. Samples taken must be representative of the dewatering discharge for any given day as required in Appendix G (standard permit conditions), Part G.10.2. d. Test methods. Samples must be measured using a turbidity meter that reports results in nephelometric turbidity units (NTUs) and conforms with a Part 136-approved method (e.g., methods 180.1 and 2130). You are required to use the meter, and conduct a calibration verification prior to each day's use, consistent with the manufacturer's instructions. 3.3.2 Turbidity benchmark a. The benchmark threshold for turbidity for this permit is 50 NTUs (referred to elsewhere in this permit as the "standard 50 NTU benchmark") unless EPA has authorized the use of an alternate benchmark in accordance with Part 3.3.2b. b. Request for alternate benchmark threshold. i. At any time prior to or during your coverage under this permit, you may request that EPA approve a benchmark for your site that is higher than 50 NTUs if you have information demonstrating the higher number is the same as your receiving water's water quality standard for turbidity. Unless EPA approves an alternate benchmark, you will be required to use the standard 50 NTU benchmark. To request approval of an alternate benchmark, you must submit the following information to your applicable EPA Regional Office (see Appendix K) (a) The current turbidity water quality standard that applies to your receiving 60 For instance, if Operator A relies on Operator B to meet the Part 3.3.1 turbidity monitoring requirements, the Part 3.3.4 reporting and recordkeeping requirements, and the Part 5.2.2 corrective action provisions when applicable, Operator A does not have to duplicate these same functions if Operator B is implementing them for both operators to be in compliance with the permit. However, Operator A remains responsible for complying with these permit requirements if Operator B fails to take actions that were necessary for Operator A to comply with the permit.See also footnote 83. EPA notes that both Operator A and B are required to submit turbidity monitoring reports as required under Part 3.3.4, however, Operator A's report does not need to include the data collected by Operator B as long as Operator B submits the required data and Operator A's report indicates that it is relying on Operator B to report the data.See Part 3.3.4a. 61 Operators may find it useful to consult EPA's Monitoring and Inspection Guide for Construction Dewatering, available at i sources l.00l and....................... „-..g.j Ilafes,which provides guidelines on how to correct) monitor for turbidity, determine if the week) ....I p g Y Y- Y average exceeds the benchmark, and, if so, how to proceed with corrective action. Page 25 2022 Construction General Permit (CGP) water and the source/citation.62 (b) If the applicable turbidity water quality standard requires information on natural or background turbidity levels (e.g., "no more than 10 NTU above natural turbidity levels") to determine the specific standard for the receiving water, include available data that can be used to establish the natural turbidity levels of your receiving water (including literature studies or Federal, State, Tribal, or local government data). Data must be representative of the natural turbidity levels of your specific receiving water. Identify the source(s) of all data provided, including if the data are from samples you collected of the receiving water. ii. EPA will inform you of its decision on whether to approve the requested alternate benchmark within 30 days. EPA may approve your request, request additional time (e.g., if additional information is needed to substantiate the data you provided), or deny your request. Unless and until EPA approves your request to use an alternate benchmark, you are required to use the standard benchmark of 50 NTUs and take any required corrective actions if an exceedance occurs. 3.3.3 Comparison of turbidity samples to benchmark. Compare the weekly average63 of your turbidity monitoring results to the standard 50 NTU benchmark, or alternate benchmark if approved by EPA. a. If the weekly average of your turbidity monitoring results exceeds the standard benchmark (or your approved alternate benchmark), you are required to conduct follow-up corrective action in accordance with Part 5.2.2 and document any corrective action taken in your corrective action log in accordance with Part 5.4. b. For averaging purposes, a "monitoring week" starts with a Monday and ends on Sunday. Once a new monitoring week starts, you will need to calculate a new average for that week of turbidity monitoring results.64 A weekly average may consist of one or more turbidity monitoring results. c. Although you are not required to collect and analyze more than one turbidity sample per day from your dewatering discharge, if you do collect and analyze more than one sample on any given day, you must include any additional results in the 62 For instance, if your site is located in Washington, DC, and you are discharging to a Class B water,for which the water quality standard is that turbidity may not increase above ambient levels by more than 20 percent,you would reference "Water Quality Standards for the District of Columbia, Chapter 11,Section 1104.8.55 63 A "weekly average" is defined as the sum of all of the turbidity samples taken during a "monitoring week" divided by the number of samples measured during that week.Average values should be calculated to the nearest whole number. 64 For example, if turbidity samples from your dewatering discharge in week 1 result in values of 30 NTU on Tuesday, 40 NTU on Wednesday, and 45 NTU on Thursday,your weekly average turbidity value would be 38.33 NTU ((30+40+45) =3=38 NTU). If in week 2,your turbidity samples resulted in values of 45 NTU on Monday, 30 NTU on Tuesday, 25 NTU on Wednesday, and 15 NTU on Thursday,you would calculate a new average for that week,which would yield an average turbidity value of 28.75 NTU ((45+30+25+15) =4=29 NTU). By comparison, if your samples on consecutive days from Friday to Monday were 60 NTU,45 NTU,40 NTU, and 43 NTU, respectively, and there are no other dewatering discharges for the remainder of the week,you would calculate one weekly average for the Friday to Sunday to be 48 NTU ((60+45+40) =3=48 NTU), and a separate weekly average for the one Monday to be 43 NTU (43= 1 = 43 NTU). Page 26 2022 Construction General Permit (CGP) calculation of your weekly average (i.e., add all individual results for that monitoring week and divide by the total number of samples).65 d. If you are conducting turbidity monitoring for more than one dewatering discharge point, you must calculate a weekly average turbidity value for each discharge point and compare each to the turbidity benchmark. 3.3.4 Reporting and recordkeeping. a. You must submit reports of your weekly average turbidity data to EPA no later than 30 days following the end of each monitoring quarter. If there are monitoring weeks in which there was no dewatering discharge, or if there is a monitoring quarter with no dewatering discharge, indicate this in your turbidity monitoring report. If another operator associated with your same site is conducting turbidity monitoring on your behalf pursuant to Part 3.3, indicate this in your turbidity monitoring report. b. For the purposes of this permit, the following monitoring quarters and reporting deadlines apply: Table 3.Monitoring Quarters and Deadlines for Reporting Turbidity Benchmark Monitoring Data. Monitoring Months Reporting Deadline (no later than 30 Quarter# days after end of the monitoring quarter 1 January 1 -March 31 April 30 2 April 1 -June 30 July 30 3 July 1 -September 30 October 30 4 October 1 -December 31 1 January 30 c. You must use EPA's NPDES eReporting Tool (NeT) to electronically submit your quarterly turbidity data, unless, consistent with Part 1.4.2, you received a waiver from your applicable EPA Regional Office. If the EPA Regional Office grants you approval to use a paper turbidity monitoring report form, and you elect to use it, you must complete the form in Appendix K. If EPA approves of your request to use an alternate turbidity benchmark pursuant to Part 3.3.2b, EPA will substitute the alternate benchmark in your NeT account. d. For each day in which you are required to monitor, you must record the monitoring information required by Appendix G, Parts G.10.2 and G.10.3 and retain all such information for a period of at least three years from the date this permit expires or from the date your authorization is terminated. 65 For example,if during a monitoring week you take two turbidity samples on Tuesday with a value of 30 NTU and 35 NTU,three samples on Wednesday with a value of 40 NTU,45 NTU, and 48 NTU,and one sample on Thursday with a value of 45 NTU,your weekly average turbidity value for this week would be 41 NTU ((30+35+40+45+48+45) =6=41 NTU).

You are responsible for ensuring that any person conducting inspections pursuant to this Part is a "qualified person." A qualified person is someone who has completed the training required by Part 6.3. 4.2 FREQUENCY OF INSPECTIONS.66 At a minimum, you must conduct a site inspection in accordance with one of the two schedules listed below, unless you are subject to the Part 4.3 site inspection frequency for discharges to sediment or nutrient-impaired or high quality waters, or qualify for a Part 4.4 reduction in the inspection frequency: 4.2.1 At least once every seven (7) calendar days; or 4.2.2 Once every 14 calendar days and within 24 hours67 of the occurrence of: a. A storm event that produces 0.25 inches or more of rain within a 24-hour period. L If a storm event produces 0.25 inches or more of rain within a 24-hour period (including when there are multiple, smaller storms that alone produce less than 0.25 inches but together produce 0.25 inches or more in 24 hours), you are required to conduct one inspection within 24 hours of when 0.25 inches of rain or more has fallen. 66 Inspections are only required during the site's normal working hours. 67 For the purposes of the inspection requirements in this Part,conducting an inspection "within 24 hours" means that once either of the two conditions in Parts 4.2.2a or 4.2.2b are met you have 24 hours from that time to conduct an inspection. For clarification,the 24 hours is counted as a continuous passage of time, and not counted by business hours (e.g.,3 business days of 8 hours each). When the 24-hour inspection time frame occurs entirely outside of normal working hours, you must conduct an inspection by no later than the end of the next business day. Page 28 2022 Construction General Permit (CGP) ii. If a storm event produces 0.25 inches or more of rain within a 24-hour period on the first day of a storm and continues to produce 0.25 inches or more of rain on subsequent days, you must conduct an inspection within 24 hours of the first day of the storm and within 24 hours after the last day of the storm that produces 0.25 inches or more of rain (i.e., only two inspections would be required for such a storm event).68 b. A discharge caused by snowmelt from a storm event that produces 3.25 inches69 or more of snow within a 24-hour period. You are required to conduct one inspection once the discharge of snowmelt from a 3.25-inch or more snow accumulation occurs. Additional snowmelt inspections are only required if following the discharge from the first snowmelt, there is a discharge from a separate storm event that produces 3.25 inches or more of snow. 4.2.3 To determine whether a storm event meets either of the thresholds in Parts 4.2.2a or 4.2.2b: a. For rain, you must either keep a properly maintained rain gauge on your site, or obtain the storm event information from a weather station that is representative of your location. For any 24-hour period during which there is 0.25 inches or more of rainfall, you must record the total rainfall measured for that day in accordance with Part 4.7.1 d. b. For snow, you must either take measurements of snowfall at your site,70 or rely on similar information from a local weather forecasting provider that is representative of your location. 4.3 INCREASE IN INSPECTION FREQUENCY FOR CERTAIN SITES. The increased inspection frequencies established in this Part take the place of the Part 4.2 inspection frequencies for the portion of the site affected. 4.3.1 For any portion of the site that discharges to a sediment or nutrient-impaired water or to a water that is identified by your State..Tribe, or EPA as Tier 2,Tier 2.5, or Tier 3 for antidegradation purposes (see Part 3.2), you must conduct an once every seven (7) calendar days and within 24 hours of the occurrence of a storm event that produces 0.25 inches or more of rain within a 24-hour period, or within 24 hours of a snowmelt discharge from a storm event that produces 3.25 inches or more of snow within a 24-hour period. 68 For example, if 0.30 inches of rain falls on Day 1,0.25 inches of rain falls on Day 2, and 0.10 inches of rain fall on Day 3,you would be required to conduct a first inspection within 24 hours of the Day 1 rainfall and a second inspection within 24 hours of the Day 2 rainfall, but a third inspection would not be required within 24 hours of the Day 3 rainfall. 69 This is the amount of snow that is equivalent to 0.25 inches of rain, based on information from the National Oceanic and Atmospheric Administration (NOAA) indicating that 13 inches of snow is, on average, equivalent to 1 inch of rain.See.Ih�.::I::::I:..p.5..m.. ..inssll.irk.........aa....gov/educa�.l.-ii n/svi x101/ iinfer/fa /. 70 For snowfall measurements, EPA suggests use of NOAA's National Weather Service guidelines at lh�eir.gov/III/sino measuiremeryL These guidelines recommend use of a "snowboard" (a piece of wood about 16 inches by 16 inches) that is placed in an unobstructed part of the site on a hard surface. Page 29 2022 Construction General Permit (CGP) Refer to Parts 4.2.3a and 4.2.3b for the requirements to determine if a storm event produces enough rain or snow to trigger the inspection requirement. 4.3.2 For sites discharging dewatering water, you must conduct an inspection in accordance with Part 4.6.3 during the discharge once per day on which the discharge occurs. The Part 4.2 inspection frequency still applies to all other portions of the site, unless the site is affected by either the increased frequency in Part 4.3.1 or the reduced frequency in Part 4.4. 4.4 REDUCTIONS IN INSPECTION FREQUENCY 4.4.1 Stabilized areas. a. You may reduce the frequency of inspections to twice per month for the first month, no more than 14 calendar days apart, then once per month until permit coverage is terminated consistent with Part 8 in any area of your site where the stabilization steps in Part 2.2.14a have been completed. If construction activity resumes in this portion of the site at a later date, the inspection frequency immediately increases to that required in Parts 4.2 and 4.3, as applicable. You must document the beginning and ending dates of this period in your SWPPP. b. Exception. For "linear construction sites" (as defined in Appendix A) where disturbed portions have undergone final stabilization at the same time active construction continues on others, you may reduce the frequency of inspections to twice per month for the first month, no more than 14 calendar days apart, in any area of your site where the stabilization steps in Part 2.2.14a have been completed. After the first month, inspect once more within 24 hours of the occurrence of a storm event that produces 0.25 inches of rain or more within a 24-hour period, or within 24 hours of a snowmelt discharge from a storm event that produces 3.25 inches or more of snow within a 24-hour period. If there are no issues or evidence of stabilization problems, you may suspend further inspections. If "wash-out" of stabilization materials and/or sediment is observed, following re-stabilization, inspections must resume at the inspection frequency required in Part 4.4.1 a. Inspections must continue until final stabilization is visually confirmed following a storm event that produces 0.25 inches of rain or more within a 24-hour period. 4.4.2 Arid, semi-arid, or drought-stricken areas (as defined in Appendix A). If it is the seasonally dry period7l or a period in which drought is occurring, you may reduce the frequency of inspections to once per month and within 24 hours of the occurrence of a storm event that produces 0.25 inches of rain or more within a 24-hour period, or within 24 hours of a snowmelt discharge from a storm event that produces 3.25 inches or more of snow within a 24-hour period. You must document that you are using this reduced schedule and the beginning and ending dates of the seasonally dry period in your SWPPP. Follow the procedures in Part 4.2.3a and 4.2.3b, accordingly, to determine if a storm event occurs that produces 0.25 inches or more of rain or 3.25 inches or more of snow within a 24-hour period. For any 24-hour period during which there is 0.25 inches or more of rainfall, or 3.25 inches or more of snow, you must record the total rainfall or snow measured for that day in accordance with Part 4.7.1 d. >> See footnote 44. Page 30 2022 Construction General Permit (CGP) 4.4.3 Frozen conditions: a. If you are suspending construction activities due to frozen conditions, you may temporarily suspend inspections on your site until thawing conditions (as defined in Appendix A) begin to occur if: i. Discharges are unlikely due to continuous frozen conditions that are likely to continue at your site for at least three (3) months based on historic seasonal averages.72 If unexpected weather conditions (such as above freezing temperatures or rain events) make discharges likely, you must immediately resume your regular inspection frequency as described in Parts 4.2 and 4.3, as applicable; ii. Land disturbances have been suspended; and iii. All disturbed areas of the site have been stabilized in accordance with Part 2.2.14a. b. If you are still conducting construction activities during frozen conditions, you may reduce your inspection frequency to once per month if: i. Discharges are unlikely due to continuous frozen conditions that are likely to continue at your site for at least three (3) months based on historic seasonal averages. If unexpected weather conditions (such as above freezing temperatures or rain events) make discharges likely, you must immediately resume your regular inspection frequency as described in Parts 4.2 and 4.3, as applicable; and ii. Except for areas in which you are actively conducting construction activities, disturbed areas of the site have been stabilized in accordance with Part 2.2.14a. You must document the beginning and ending dates of this period in your SWPPP. 4.5 AREAS THAT MUST BE INSPECTED During your site inspection, you must at a minimum inspect the following areas of your site: 4.5.1 All areas that have been cleared, graded, or excavated and that have not yet completed stabilization consistent with Part 2.2.14a; 4.5.2 All stormwater controls, including pollution prevention controls, installed at the site to comply with this permit;73 4.5.3 Material, waste, borrow, and equipment storage and maintenance areas that are covered by this permit; 4.5.4 All areas where stormwater typically flows within the site, including constructed or natural site drainage features designed to divert, convey, and/or treat stormwater; 4.5.5 All areas where construction dewatering is taking place, including controls to treat the dewatering discharge and any channelized flow of water to and from those controls; 72 Use data sets that include the most recent data available to account for recent precipitation patterns and trends. 73 This includes the requirement to inspect for sediment that has been tracked out from the site onto paved roads,sidewalks, or other paved areas consistent with Part 2.2.4. Page 31 2022 Construction General Permit (CGP) 4.5.6 All points of discharge from the site; and 4.5.7 All locations where stabilization measures have been implemented. You are not required to inspect areas that, at the time of the inspection, are considered unsafe to your inspection personnel. 4.6 REQUIREMENTS FOR INSPECTIONS 4.6.1 During each site inspection, you must at a minimum: a. Check whether all stormwater controls (i.e., erosion and sediment controls and pollution prevention controls) are properly installed, appear to be operational, and are working as intended to minimize pollutant discharges. b. Check for the presence of conditions that could lead to spills, leaks, or other accumulations of pollutants on the site. c. Identify any locations where new or modified stormwater controls are necessary to meet the requirements of Parts 2 and/or 3. d. Check for signs of visible erosion and sedimentation (i.e., sediment deposits) that have occurred and are attributable to your discharge at points of discharge and, if applicable, on the banks of any receiving waters flowing within or immediately adjacent to the site; e. Check for signs of sediment deposition that are visible from your site and attributable to your discharge (e.g., sand bars with no vegetation growing on top in receiving waters or in other constructed or natural site drainage features, or the buildup of sediment deposits on nearby streets, curbs, or open conveyance channels). f. Identify any incidents of noncompliance observed. 4.6.2 If a discharge is occurring during your inspection: a. Identify all discharge points at the site; and b. Observe and document the visual quality of the discharge, and take note of the characteristics of the stormwater discharge, including color; odor; floating, settled, or suspended solids; foam; oil sheen; and other indicators of stormwater pollutants. Check also for signs of these same pollutant characteristics that are visible from your site and attributable to your discharge in receiving waters or in other constructed or natural site drainage features. 4.6.3 For dewatering inspections conducted pursuant to Parts 4.3.2, record the following in a report within 24 hours of completing the inspection: a. The inspection date; b. Names and titles of personnel making the inspection; c. Approximate times that the dewatering discharge began and ended on the day of inspection;74 d. Estimates of the rate (in gallons per day) of discharge on the day of inspection; 74 If the dewatering discharge is a continuous discharge that continues after normal business hours, indicate that the discharge is continuous. Page 32 2022 Construction General Permit (CGP) e. Whether or not any of the following indications of pollutant discharge were observed at the point of discharge to any receiving waters flowing through or immediately adjacent to the site and/or to constructed or natural site drainage features or storm drain inlets:75 L a sediment plume, suspended solids, unusual color, presence of odor, decreased clarity, or presence of foam; and/or H. a visible sheen on the water surface or visible oily deposits on the bottom or shoreline of the receiving water; and f. Photographs of (1) the dewatering water prior to treatment by a dewatering control(s) and the final discharge after treatment; (2) the dewatering control(s); and (3) the point of discharge to any receiving waters flowing through or immediately adjacent to the site and/or to constructed or natural site drainage features, storm drain inlets, and other conveyances to receiving waters. You must also comply with the Part 4.7.2, 4.7.3, and 4.7.4 requirements for signing the reports, keeping them available on site, and retaining copies. 4.6.4 Based on the results of your inspection: a. Complete any necessary maintenance repairs or replacements under Part 2.1.4 or under Part 5, whichever applies; and b. Modify your SWPPP site map in accordance with Part 7.4.1 to reflect changes to your stormwater controls that are no longer accurately reflected on the current site map. 4.7 INSPECTION REPORT 4.7.1 You must complete an inspection report within 24 hours of completing any site inspection. Each inspection report (except for dewatering inspection reports, which are covered in Part 4.6.3) must include the following: a. The inspection date; b. Names and titles of personnel making the inspection; c. A summary of your inspection findings, covering at a minimum the observations you made in accordance with Part 4.6, including any problems found during your inspection that make it necessary to perform routine maintenance pursuant to Part 2.1.4b or corrective action pursuant to Part 5. Include also any documentation as to why the corrective action procedures under Part 5 are unnecessary to fix a problem that repeatedly occurs as described in Part 2.1.4c; d. If you are inspecting your site at the frequency specified in Part 4.2.2, Part 4.3, or Part 4.4.1 b, and you conducted an inspection because of a storm event that produced rainfall measuring 0.25 inches or more within a 24-hour period, you must include the applicable rain gauge or weather station readings that triggered the inspection. Similarly, if you conducted an inspection because of a snowmelt discharge from a storm event that produced 3.25 inches or more of snow within a 24-hour period, you must include any measurements taken of snowfall at your site, or weather station information you relied on; and 75 If the operator observes any of these indicators of pollutant discharge, corrective action is required consistent with Parts 5.1.5b and 5.2.2. Page 33 2022 Construction General Permit (CGP) e. If you determined that it is unsafe to inspect a portion of your site, you must describe the reason you found it to be unsafe and specify the locations to which this condition applies. 4.7.2 Each inspection report must be signed by the operator's signatory in accordance with Appendix G, Part G.1 1 of this permit. 4.7.3 You must keep a copy of all inspection reports at the site or at an easily accessible location, so that it can be made immediately available at the time of an on-site inspection or upon request by EPA.76 4.7.4 You must retain all inspection reports completed for this Part for at least three (3) years from the date that your permit coverage expires or is terminated. 4.8 INSPECTIONS BY EPA You must allow EPA, or an authorized representative of EPA, to conduct the following activities at reasonable times. To the extent that you are utilizing shared controls, that are not on site, to comply with this permit, you must make arrangements for EPA to have access at all reasonable times to those areas where the shared controls are located. 4.8.1 Enter onto all areas of the site, including any construction support activity areas covered by this permit, any off-site areas where shared controls are utilized to comply with this permit, discharge locations, adjoining waterbodies, and locations where records are kept under the conditions of this permit; 4.8.2 Access and copy any records that must be kept under the conditions of this permit; 4.8.3 Inspect your construction site, including any construction support activity areas covered by this permit (see Part 1.2.1 c), any stormwater controls installed and maintained at the site, and any off-site shared controls utilized to comply with this permit; and 4.8.4 Sample or monitor for the purpose of ensuring compliance. 5 CORRECTIVE ACTIONS 5.1 CONDITIONS TRIGGERING CORRECTIVE ACTION. You must take corrective action to address any of the following conditions identified at your site: 5.1.1 A stormwater control needs a significant repair or a new or replacement control is needed, or, in accordance with Part 2.1.4c, you find it necessary to repeatedly (i.e., three (3) or more times) conduct the same routine maintenance fix to the same control at the same location (unless you document in your inspection report under Part 4.7.1 c that the specific reoccurrence of this same problem should still be addressed as a routine maintenance fix under Part 2.1.4); or 5.1.2 A stormwater control necessary to comply with the requirements of this permit was never installed, or was installed incorrectly; or 76 Inspection reports may be prepared,signed, and kept electronically, rather than in paper form, if the records are: (a) in a format that can be read in a similar manner as a paper record; (b) legally dependable with no less evidentiary value than their paper equivalent; and (c) immediately accessible to the inspector during an inspection to the same extent as a paper copy stored at the site would be,if the records were stored in paper form. For additional guidance on the proper practices to follow for the electronic retention of inspection report records,refer to the Fact Sheet discussion related to Part 4.7.3. Page 34 2022 Construction General Permit (CGP) 5.1.3 Your discharges are not meeting applicable water quality standards; 5.1.4 A prohibited discharge has occurred (see Part 1.3); or 5.1.5 During discharge from site dewatering activities: a. The weekly average of your turbidity monitoring results exceeds the 50 NTU benchmark (or alternate benchmark if approved by EPA pursuant to Part 3.3.2b); or b. You observe or you are informed by EPA, State, or local authorities of the presence of the conditions specified in Part 4.6.3e. 5.2 CORRECTIVE ACTION DEADLINES 5.2.1 If responding to any of the Part 5.1.1, 5.1.2, 5.1.3, or5.1.4 triggering conditions, you must: a. Immediately take all reasonable steps to address the condition, including cleaning up any contaminated surfaces so the material will not discharge in subsequent storm events; and b. When the problem does not require a new or replacement control or significant repair, the corrective action must be completed by the close of the next business day; or c. When the problem requires a new or replacement control or significant repair, install the new or modified control and make it operational, or complete the repair, by no later than seven (7) calendar days from the time of discovery. If it is infeasible to complete the installation or repair within seven (7) calendar days, you must document in your records why it is infeasible to complete the installation or repair within the 7-day timeframe and document your schedule for installing the stormwater control(s) and making it operational as soon as feasible after the 7-day timeframe. Where these actions result in changes to any of the stormwater controls or procedures documented in your SWPPP, you must modify your SWPPP accordingly within seven (7) calendar days of completing this work. 5.2.2 If responding to either of the Part 5.1.5 triggering conditions related to site dewatering activities, you must: a. Immediately take all reasonable steps to minimize or prevent the discharge of pollutants until you can implement a solution, including shutting off the dewatering discharge as soon as possible depending on the severity of the condition77 taking safety considerations into account; b. Determine whether the dewatering controls are operating effectively and whether they are causing the conditions; and c. Make any necessary adjustments, repairs, or replacements to the dewatering controls to lower the turbidity levels below the benchmark or remove the visible plume or sheen. » For instance, if the weekly average of your turbidity monitoring results or a single sample is extremely high (e.g., a single turbidity sample results in 355 NTUs or higher),you should take action to safely shut off the discharge so that you can evaluate the cause of the high turbidity. Note:A single turbidity sample of 355 NTUs or higher means that the weekly average turbidity value will exceed 50 NTU regardless of the turbidity values the other days during the week. Page 35 2022 Construction General Permit (CGP) When you have completed these steps and made any changes deemed necessary, you may resume discharging from your dewatering activities. 5.3 CORRECTIVE ACTION REQUIRED BY EPA You must comply with any corrective actions required by EPA as a result of permit violations found during an inspection carried out under Part 4.8. 5.4 CORRECTIVE ACTION LOG 5.4.1 For each corrective action taken in accordance with this Part, you must record the following in a corrective action log: a. Within 24 hours of identifying the corrective action condition, document the specific condition and the date and time it was identified. b. Within 24 hours of completing the corrective action (in accordance with the deadlines in Part 5.2), document the actions taken to address the condition, including whether any SWPPP modifications are required. 5.4.2 Each entry into the corrective action log, consisting of the information required by both Parts 5.4.1 a and 5.4.1 b, must be signed by the operator's signatory in accordance with Appendix G, Part G.1 1.2 of this permit. 5.4.3 You must keep a copy of the corrective action log at the site or at an easily accessible location, so that it can be made immediately available at the time of an on-site inspection or upon request by EPA.78 5.4.4 You must retain the corrective action log for at least three (3) years from the date that your permit coverage expires or is terminated. 6 STORMWATER TEAM FORMATION/STAFF TRAINING REQUIREMENTS 6.1 STORMWATER TEAM Each operator, or group of multiple operators, must assemble a "stormwater team" that will be responsible for carrying out activities necessary to comply with this permit. The stormwater team must include the following people: a. Personnel who are responsible for the design, installation, maintenance, and/or repair of stormwater controls (including pollution prevention controls); b. Personnel responsible for the application and storage of treatment chemicals (if applicable); c. Personnel who are responsible for conducting inspections as required in Part 4.1; and d. Personnel who are responsible for taking corrective actions as required in Part 5. Members of the stormwater team must be identified in the SWPPP pursuant to Part 7.2.2. 78 The corrective action log may be prepared,signed, and kept electronically, rather than in paper form, if the records are: (a) in a format that can be read in a similar manner as a paper record; (b) legally dependable with no less evidentiary value than their paper equivalent; and (c) immediately accessible to the inspector during an inspection to the same extent as a paper copy stored at the site would be, if the records were stored in paper form. For additional guidance on the proper practices to follow for the electronic retention of corrective action log records, refer to the Fact Sheet discussion related to Part 4.7.3. Page 36 2022 Construction General Permit (CGP) 6.2 GENERAL TRAINING REQUIREMENTS FOR STORMWATER TEAM MEMBERS Prior to the commencement of construction activities, you must ensure that all persons79 assigned to the stormwater team understand the requirements of this permit and their specific responsibilities with respect to those requirements, including the following related to the scope of their job duties: a. The permit requirements and deadlines associated with installation, maintenance, and removal of stormwater controls, as well as site stabilization; b. The location of all stormwater controls on the site required by this permit and how they are to be maintained; c. The proper procedures to follow with respect to the permit's pollution prevention requirements; and d. When and how to conduct inspections, record applicable findings, and take corrective actions. Specific training requirements for persons conducting site inspections are included in Part 6.3. You are responsible for ensuring that all activities on the site comply with the requirements of this permit. You are not required to provide or document formal training for subcontractors or other outside service providers (unless the subcontractors or outside service providers are responsible for conducting the inspections required in Part 4, in which case you must provide such documentation consistent with Part 7.2.2), but you must ensure that such personnel understand any requirements of this permit that may be affected by the work they are subcontracted to perform. 6.3 TRAINING REQUIREMENTS FOR PERSONS CONDUCTING INSPECTIONS For projects that receive coverage under this permit on or after February 17, 2023, to be considered a qualified person under Part 4.1 for conducting inspections under Part 4, you must, at a minimum, either: a. Have completed the EPA construction inspection course developed for this permit and have passed the exam; or b. Hold a current valid construction inspection certification or license from a program that, at a minimum, covers the following:80 L Principles and practices of erosion and sediment control and pollution prevention practices at construction sites; ii. Proper installation and maintenance of erosion and sediment controls and pollution prevention practices used at construction sites; and HL Performance of inspections, including the proper completion of required reports and documentation, consistent with the requirements of Part 4. 79 If the person requiring training is a new employee who starts after you commence construction activities, you must ensure that this person has the proper understanding as required above prior to assuming particular responsibilities related to compliance with this permit. For emergency-related projects,the requirement to train personnel prior to commencement of construction activities does not apply, however, such personnel must have the required training prior to NOI submission. 80 If one of the following topics (e.g., installation and maintenance of pollution prevention practices) is not covered by the non-EPA training program,you may consider supplementing the training with the analogous module of the EPA course (e.g., Module 4) that covers the missing topic. Page 37 2022 Construction General Permit (CGP) For projects that receive coverage under this permit prior to February 17, 2023, any personnel conducting site inspections pursuant to Part 4 on your site must, at a minimum, be a person knowledgeable in the principles and practice of erosion and sediment controls and pollution prevention, who possesses the appropriate skills and training to assess conditions at the construction site that could impact stormwater quality, and the appropriate skills and training to assess the effectiveness of any stormwater controls selected and installed to meet the requirements of this permit.81 6.4 STORMWATER TEAM'S ACCESS TO PERMIT DOCUMENTS Each member of the stormwater team must have easy access to an electronic or paper copy of applicable portions of this permit, the most updated copy of your SWPPP, and other relevant documents or information that must be kept with the SWPPP. 7 STORMWATER POLLUTION PREVENTION PLAN (SWPPP) 7.1 GENERAL REQUIREMENTS All operators associated with a construction site under this permit must develop a SWPPP consistent with the requirements in Part 7 prior to their submittal of the N01.82,83, 84 The SWPPP must be kept up-to-date throughout coverage under this permit. If a SWPPP was prepared under a previous version of this permit, the operator must review and update the SWPPP to ensure that this permit's requirements are addressed prior to submitting an NOI for coverage under this permit. 7.2 SWPPP CONTENTS At a minimum, the SWPPP must include the information specified in this Part and as specified in other parts of this permit. 7.2.1 All Site Operators. Include a list of all other operators who will be engaged in construction activities at the site, and the areas of the site over which each operator has control. 81 If you receive coverage for a project prior to February 17,2023,and construction activities for the same project will continue after February 17,2023,the personnel conducting inspections do not need to take the additional training specified in Parts 6.3a and 6.3b for inspections conducted on the project site. If the same operator obtains coverage for a different project on or after February 17,2023, personnel conducting inspections would be required to meet the requirements for a qualified person by completing the training in either Part 6.3a or Part 6.3b. 82 The SWPPP does not establish the effluent limits and/or other permit terms and conditions that apply to your site's discharges; these limits, terms, and conditions are established in this permit. 83 Where there are multiple operators associated with the same site,they may develop a group SWPPP instead of multiple individual SWPPPs. Regardless of whether there is a group SWPPP or multiple individual SWPPPs, each operator is responsible for compliance with the permit's terms and conditions. In other words, if Operator A relies on Operator B to satisfy its permit obligations, Operator A does not have to duplicate those permit-related functions if Operator B is implementing them such that both operators are in compliance with the permit. However, Operator A remains responsible for permit compliance if Operator B fails to take actions necessary for Operator A to comply with the permit. In addition,all operators must ensure, either directly or through coordination with other operators,that their activities do not cause a violation or compromise any other operators' controls and/or any shared controls.See also footnote 60. 84 There are a number of commercially available products to assist operators in developing the SWPPP, as well as companies that can be hired to help develop a site-specific SWPPP.The permit does not state which are recommended, nor does EPA endorse any specific products or vendors.Where operators choose to rely on these products or services,the choice of which ones to use to comply with the requirements of this Part is a decision for the operator alone. Page 38 2022 Construction General Permit (CGP) 7.2.2 Stormwater Team. Identify the personnel (by name and position) that you have made part of the stormwater team pursuant to Part 6.1, as well as their individual responsibilities, including which members are responsible for conducting inspections. Include verification that each member of the stormwater team has received the training required by Part 6.2. Include documentation that members of the stormwater team responsible for conducting inspections pursuant to Part 4 have received the training required by Part 6.3. If personnel on your team elect to complete the EPA inspector training program pursuant to Part 6.3a, you must include copies of the certificate showing that the relevant personnel have completed the training and passed the exam. If personnel on your team elect to complete a non-EPA inspector training program pursuant to Part 6.3b, you must include documentation showing that these persons have successfully completed the program and their certification or license is still current. You must also confirm that the non-EPA inspector training program satisfies the minimum elements for such programs in Part 6.3b. 7.2.3 Nature of Construction Activities. Include the following: a.

INDIAN COUNTRY LANDS.. OR TERRITORIES The provisions in this Part provide additions to the applicable conditions of this permit to reflect specific additional conditions required as part of the State or Tribal CWA Section 401 certification process, or the Coastal Zone Management Act (CZMA) certification process, or as otherwise established by the permitting authority. The specific additional revisions and requirements only apply to activities in those specific States, Indian country, and areas in certain States with Federal Facilities or areas subject to construction projects by Federal Operators. States, Indian country, and other areas not included in this Part do not have any additions to the applicable conditions of this permit. 9.1 EPA REGION 1 9.1.1 N H R 100000 State of New Hampshire a. Should the permit coverage for an individual applicant be insufficient to achieve water quality standards, the New Hampshire Department of Environmental Services (NHDES) may prepare additional 401 certification conditions for that applicant. Any additional 401 certification conditions will follow all required NHDES public participation requirements. b. If you disturb 100,000 square feet or more of contiguous area, you must also comply with RSA 485-A:17 and Env-Wq 1500, and, unless exempt, apply for an Alteration of Terrain (AoT) permit from NHDES. This requirement also applies to a lower disturbance threshold of 50,000 square feet or more when construction occurs within the protected shoreline under the Shoreland Water Quality Protection Act (see RSA 483-B and Env-Wq 1400). A permit application must also be filed if your project disturbs an area of greater than 2,500 square feet, is within 50 feet of any surface water, and has a flow path of 50 feet or longer disturbing a grade of 25 percent or greater. Project sites with disturbances smaller than those discussed above, that have the potential to adversely affect state surface waters, are subject to the conditions of an AoT General Permit by Rule (Env-Wq 1503.03). c. You must determine that any excavation dewatering discharges are not contaminated before they will be authorized as an allowable non-stormwater discharge under this permit (see Part 1.2.2 of the Construction General Permit or CGP). In the absence of information demonstrating otherwise, the water is considered uncontaminated if there is no groundwater contamination within 1,000 feet of the groundwater dewatering location. Information on groundwater contamination can be generated over the Internet via the NHDES web site http:// des.nh.gov/ by using the One Stop Data Mapper. For a toxic substance included in the New Hampshire surface water quality standards, see Env-Wq 1703.21 (see https://www.des.nh.gov/sites/g/fi 1 es/ehbemt 341/files/documents/2020-01/Env-Wg Page 49 2022 Construction General Permit (CGP) 1700.pdf). If it is determined that the groundwater to be dewatered is near a remediation or other waste site, you must apply for the Remediation General Permit (see https://www3.epa.gov/region 1/npdes/rgp.html) d. As a minimum, you must treat any uncontaminated excavation "dewatering" discharges and "stormwater" discharges, as those terms are defined in Appendix A of the CGP, as necessary, to remove suspended solids and turbidity so that the surface waters receiving the construction discharges95 meet New Hampshire surface water quality standards for turbidity (Env-Wq 1703.11 and Env-Wq 1703.03(c)(1)c), benthic deposits (Env-Wq 1703.03(c)(1)a), and Env-Wq 1703.08) and foam, debris, scum or other visible substances (i.e., plumes or visual turbidity)96 (Env-Wq 1703.03(c)(1)b). L For all Construction Activities covered under this CGP, the following shall apply to ensure compliance with the aforementioned regulations for turbidity, benthic deposits and visible substances: Unless otherwise specified, site inspection requirements shall comply with Part 4 of the CGP. As a minimum site inspection frequency shall be in accordance with Part 4.2.2 of the CGP (and Part 4.3.2 of the CGP for sites discharging dewatering water). Site inspection frequency may be reduced in accordance with Part 4.4 of the CGP (Reductions in Inspection Frequency). Monitoring of the receiving water for visible turbidity and benthic sediment deposits shall be conducted each site inspection and results reported in the Inspection Report required in Part 4.7 of the CGP. Should visible turbidity or benthic sediment deposits attributable or partly attributable to your construction activities be present in the receiving water, the"Corrective Actions"specified in Part 5 shall be immediately implemented to correct the water quality standard violations. In addition, daily monitoring (including photographs) of the receiving water shall be conducted until there is no visible turbidity or benthic deposits. Inspection Reports required in Part 4.7 of the CGP shall include, but not be limited to, the distance downstream and the percent of the river width97 where visible turbidity was observed, and the period of time that the visible turbidity persisted. A copy of the Inspection Report(s) shall be made available to NHDES within 24 hours of receiving a written request from NHDES. ii. For Construction Activities, disturbing 5 acres or more of land at any one time (excluding areas that have been completely stabilized in accordance with the final stabilization criteria specified in Part 2.2.14.c of the CGP), the following shall 95 Construction Discharges include uncontaminated"dewatering"and"stormwater"discharges as those terms are defined in Appendix A of the CGP.Controlled construction discharges are construction discharges where the rate of flow can be regulated such as from a construction settling basin or NHDES approved flocculation system. 96 For the definition of visual turbidity,see the definition for"Non-Turbid"in Appendix A of the CGP,which states the following:""Non-Turbid"-a discharge that is free from visual turbidity.For the purposes of this permit,visual turbidity refers to a sediment plume or other cloudiness in the water caused by sediment that can be identified by an observer."[EPA interprets the text of this footnote as intending to reference the Appendix A definitions of"visual turbidity"and"non- turbid"in the final permit.] 97 The distance downstream and the percent of river width where visible turbidity(i.e.,plume) is observed is required to determine the extent of the river affected and to determine if there was a"zone of passage" (i.e.,a portion of the receiving water where there was no visible turbidity where mobile organisms could pass without being adversely impacted).The percent of river width affected is equal 100 multiplied by the width of the plume (in feet) divided by the width of the receiving water(in feet). Page 50 2022 Construction General Permit (CGP) apply to ensure compliance with the aforementioned regulations for turbidity, benthic deposits and visible substances. Item 9.1.1.d.i) above shall apply to all construction discharges and the minimum site inspection frequency shall comply with Part 4.3.1 of the CGP (and Part 4.3.2 of the CGP for sites discharging dewatering water). Site inspection frequency may be reduced in accordance with Part 4.4 of the CGP (Reductions in Inspection Frequency). With regards to controlled construction discharges, if there is no visible turbidity (i.e., plumes) or benthic deposits, and, in the absence of information demonstrating otherwise, turbidity measurements of less than or equal to 50 nephelometric turbidity units (NTU) in the controlled construction discharges at the outlet prior to mixing with the receiving surface waters, shall be presumed to meet New Hampshire surface water quality standards for the parameters listed above. As a minimum, the controlled construction discharges must be sampled at each site inspection. If any controlled construction discharge exceeds 50 NTU, or if visible turbidity or benthic sediment deposits attributable or partly attributable to any construction discharge are observed in the receiving water, then the "Corrective Actions"specified in Part 5 of the CGP shall be immediately implemented. In addition, should such violation occur, and, in order to determine compliance with surface water quality standards for turbidity (Env-Wq 1703.11 and Env-Wq 1703.03(c)(1)c), benthic deposits (Env-Wq 1703.03(c)(1)a), and Env-Wq 1703.08) and foam, debris, scum or other visible substances (Env-Wq 1703.03(c)(1)b)), turbidity monitoring shall be immediately implemented as specified below: Turbidity samples of the receiving water shall be immediately taken in the receiving water upstream and beyond the influence of the construction activity, and, unless a mixing zone98 is approved by NHDES, no more than 75 feet downstream of each controlled construction discharge that exceeded 50 NTU and no more than 75 feet downstream of each construction discharge that caused visible turbidity. Downstream samples shall be taken at locations in the receiving water that are most likely influenced by the discharge (e.g., if visible turbidity (i.e., a plume) is present, the sample shall be taken in the plume). Samples shall be collected a minimum of 2 times per day during the daylight hours at times when construction activities are most likely to cause turbidity in the receiving water and shall continue until the turbidity water quality standards are met in the receiving water (i.e., the difference between the upstream and downstream turbidity level is no greater than 10 NTU). 98 Permittees may request a distance greater than 75 feet downstream of a construction discharge for determining compliance with turbidity standards in Class B surface waters, by submitting a mixing zone request to NHDES that complies with Env-Wq 1707.02.If a mixing zone is approved,NHDES is required to include conditions to ensure that the criteria on which the approval is based are met(Env-Wq 1707.03). Page 51 2022 Construction General Permit (CGP) If water quality standards are not met during daylight hours on any day, sampling shall resume the next day and continue no fewer than 2 times per day until water quality standards are met. The date, time, location and results of turbidity measurements, as well as a summary identifying the cause of the violations, corrective actions that were implemented, the period of time that the receiving water exceeded turbidity standards and the distance downstream and the percent of the river width where visible turbidity was observed, and the period of time that the visible turbidity persisted, shall be recorded and included in the Inspection Report required in Part 4.7 of the CGP. Turbidity measurements shall be conducted via a field meter in accordance with the requirements for turbidity specified in Table 1 B in 40 CFR 136.3 (see 40 CFR §136.3 Identification of test procedures - Code of Federal Regulations ecfr.io). Field meters shall be calibrated every day sampling is conducted and prior to the first sample. e. Construction site owners and operators are encouraged to consider opportunities for post- construction groundwater recharge using infiltration best management practices (BMPs) during site design and preparation of the SWPPP in order to assure compliance with Env-Wq 1703.03 and Env-Wq 1703.11. If your construction site is in a town that is required to obtain coverage under the NPDES General Permit for discharges from Municipal Separate Storm Sewer Systems (MS4) you may be required to use such practices. The SWPPP must include a description of any on-site infiltration that will be installed as a post-construction stormwater management measure or reasons for not employing such measures such as 1) The facility is located in a wellhead protection area as defined in RSA 485- C:2; or 2) The facility is located in an area where groundwater has been reclassified to GAA, GA1 or GA2 pursuant to RSA 485-C and Env-DW 901; or3) Any areas that would be exempt from the groundwater recharge requirements contained in Env-Wq 1507.04, including all land uses or activities considered to be a "High-load Area" (see Env-Wq 1502.30). For design considerations for infiltration measures see Env-Wq 1508.06. Note that there may be additional local requirements that fall under the NH MS4 permittee's Authorization to Discharge Permit for those regulated areas. f. Appendix F of the CGP contains information regarding Tier 2, or high quality waters in the various states. [EPA notes that this information has now been moved to h. ., tr ti r i r i -r r -tools ]. pji t Although there is no official list of tier 2 waters for New Hampshire, it can be assumed that all New Hampshire surface waters are tier 2 for turbidity unless 1) the surface water that you are proposing to discharge into is listed as impaired for turbidity in the states listing of impaired waters (see https://nhdes-surface-water- quality-assessment-site-nhdes.hub.arcgis.com/) or 2) sampling upstream of the proposed discharge location shows turbidity values greater than 10 NTU (Env-Wq 1703.11). A single grab sample collected during dry weather (no precipitation within 48 hours) is acceptable. g. To ensure compliance with RSA 485-C, RSA 485-A, RSA 485-A:131 1(a), Env-Wq 1700 and Env-Wq 302, the following information may be requested by NHDES. This information must be kept on site unless you receive a written request from NHDES that it be sent to the address shown below in 9.1.1.h. Page 52 2022 Construction General Permit (CGP) i. A list of all non-stormwater discharges that occur at the facility, including their source locations and the control measures being used (see Part 1.2.2 of the CGP). ii.

Box 95 Concord, NH 03302-0095. 9.1.2 MAR100000 Commonwealth of Massachusetts (except Indian country) a. All discharges covered by the Construction General Permit shall comply with the provisions pursuant to 314 CMR 3.00, 314 CMR 4.00, 314 CMR 9.00, including applicable construction stormwater standards and 310 CMR 10.00. b. Pursuant to 314 CMR 3.11 (2)(a)6., and in accordance with MassDEP's obligation under 314 CMR 4.05(5)(e) to maintain surface waters free from pollutants in concentrations or combinations that are toxic to humans, aquatic life, or wildlife, permittees are prohibited from discharging dewatering water under the CGP from sites that are designated as Superfund/CERCLA or RCRA, and must make accommodations to dispose of the dewatering discharges appropriately, such as coverage under the Remediation General Permit (RGP). c. Pursuant to 314 CMR 3.11 (2)(a), and in accordance with MassDEP's obligation to protect Outstanding Resource Waters under 314 CMR 4.04(3), applicants seeking coverage under the 2022 CGP that propose to carry out construction activities near Outstanding Resource Waters as identified in 314 CMR 4.06, shall submit to MassDEP for review: i. a copy of the Stormwater Pollution Prevention Plan (SWPPP), ii. a copy of the EPA NOI, and iii. MassDEP's Stormwater BMP Checklist. For purposes of this review, the permittee shall submit these documents to MassDEP at the same time they are submitted to EPA. Instructions on how to submit these documents to MassDEP and where to find the MassDEP Stormwater BMP Checklist and obtain authorization to discharge can be found here: https://www.mass.gov/how-to/wm-15-npdes-general-permit- notice-of- intent. d. Pursuant to 314 CMR 3.11 (2)(a)6., and in accordance with MassDEP's obligation under 314 CMR 4.05(5)(e) to maintain surface waters free from pollutants in concentrations or combinations that are toxic to humans, aquatic life, or wildlife, applicants that propose to dewater under the 2022 CGP and plan to discharge to certain waters as described below, shall determine that any dewatering discharges are not contaminated by testing the proposed discharge as described below as part of the application for WM15 authorization. Unless otherwise specified, testing described in this section should be conducted using the methods in 40 CFR 136. i. Applicants for sites that plan to discharge to Outstanding Resource Waters as identified in 314 CMR 4.06 shall test one sample of the proposed dewatering discharge water for pH, E. Coli (for discharges to freshwater), fecal coliform (for Page 53 2022 Construction General Permit (CGP) discharges to salt water), Enterococci (for discharges to salt water), total suspended solids, oil and grease, total nitrogen, total phosphorus, and all parameters with numeric criteria listed in the Massachusetts Surface Water Quality Standards at 314 CMR 4.05(e). Results shall be reported to MassDEP as part of the WM 15 application. To determine if the dewatering discharge could be covered under the 2022 CGP, the effluent at zero dilution must meet numeric water quality criteria. If the effluent does not meet numeric water quality criteria, the applicant shall contact EPA Region 1 to discuss coverage under the Remediation General Permit. ii. Applicants for sites that propose to discharge to Public Water Supplies (314 CMR 4.06(1)(d)1) shall also test one sample of the proposed dewatering discharge water for per- and polyfluoroalkyl substances (PFAS), as outlined in the table below. Results shall be reported to MassDEP as part of the WM15 application. If any PFAS compounds are detected, the applicant shall apply for coverage under the NPDES Remediation General Permit for Massachusetts if required. PEAS Testing Parameters for Discharges to Public Drinking Water Supplies99 Perfluorohexanesulfonic acid (PFHxS),grab Report ng/L Perfluoroheptanoic acid (PFHpA), grab Report ng/L Perfluorononanoic acid (PFINIA), grab Report ng/L Perfluorooctanesulfonic acid (PFOS),grab Report ng/L Perfluorooctanoic acid (PFOA), grab Report ng/L Perfluorodecanoic acid (PFDA), grab Report ng/L iii. Applicants for sites that propose to discharge to an impaired water as identified in the most recent final Massachusetts Integrated List of Waters,shall test one sample of the proposed dewatering discharge water for the parameter(s) for which the waterbody is impaired. To determine if the dewatering discharge could be covered under the 2022 CGP, the effluent at zero dilution must meet numeric water quality criteria. If the effluent does not meet numeric water quality criteria, the applicant shall contact EPA Region 1 to discuss coverage under the Remediation GeneralPermit and shall apply for RGP coverage if required. iv. For dewatering discharges to all other waters, if any pollutants are knownor believed present in the proposed dewatering discharge water, the applicant shall apply for coverage under the NPDES Remediation General Permit for Massachusetts if required. For the purposes of this condition, a pollutant is "known present" if measured above the analytical detection limit using a sufficiently sensitive test method in an environmental sample, and "believed present" if a pollutant has not been measured in an environmental sample but will be added or generated prior to discharge, such as through a treatment process. Consequently, a pollutant is "known absent" if measured as non-detect relative to the analytical detection limit using a sufficiently sensitive test method in an environmental sample, and "believed absent" if a pollutant has not been measured in an environmentalsample but will not be added or generated prior to discharge and is not a parameter that applies to the applicable activity category for a site. If any pollutants are known or believed present in the 99 PFAS testing shall follow established EPA methods 537 or 537.1 for drinking water until EPA Method 3512 for non- potable water becomes available. Page 54 2022 Construction General Permit (CGP) proposed dewatering discharge water, the applicant shall test one sample of the proposed dewatering discharge water for the pollutants known or believed to be present. To determine if the dewatering discharge could be covered under the 2022 CGP, the effluent at zero dilution must meet numeric water quality criteria. If the effluent does not meet numeric water quality criteria, the applicant shall contact EPA Region 1 to discuss coverage under the Remediation General Permit. e. Pursuant to 314 CMR 3.11 (2)(a), and in accordance with MassDEP's obligation to protect Outstanding Resource Waters under 314 CMR 4.04(3), applicants that propose to dewater under the 2022 CGP and discharge to Outstanding Resource Waters as identified in 314 CMR 4.06, shall submit the SWPPP and associated documents to MassDEP to review. MassDEP shall complete review within 30 daysof receipt. f. Pursuant to 314 CMR 3.11 (2)(a)6., and in accordance with MassDEP's obligation under 314 CMR 4.05 to maintain surface waters free from color and turbidity in concentrations or combinations that are aesthetically objectionable or would impair any use assigned to the waterbody, permittees that have been authorized to dewater under the 2022 CGP and that discharge to Outstanding Resource Waters as identified in 314 CMR 4.06 shall carry out daily benchmark monitoring for turbidity'oo for the duration of dewatering. Permittees shall compare the weekly average of the turbidity monitoring results with the established benchmark turbidity value of 25 Nephelometric Turbidity Units (NTU). If a permittee's weekly average turbidity results exceed the benchmark, the operator shall conduct follow-up corrective action to determine the source of the problem and to make any necessary repairs or upgrades to the dewatering controls to lower the turbidity levels. The permittee shall document any corrective action taken in its corrective action log. Furthermore, permittees at these sites shall carry out inspections at higher frequency, specifically, daily inspections of the dewatering discharge treatment for the duration of the discharge. The permittee shall inspect the site for sediment plume or whether a hydrocarbon sheen is visible at the point of discharge, estimate the flow rate at the point of discharge, and inspect the site downstream to assess whether sedimentation is attributable to the dewatering discharges. g. Pursuant to 314 CMR 3.11 (2)(a)6., and in accordance with MassDEP's obligation under 314 CMR 4.05 to maintain surface waters free from color and turbidity in concentrations or combinations that are aesthetically objectionable or would impair any use assigned to the waterbody, permittees shall store materials outside the Base Flood Elevation 101 when feasible to prevent displacing runoff and erosion. h. Pursuant to 314 CMR 3.11 (2)(a), and in accordance with MassDEP's obligation to maintain surface waters free from nutrients in concentrations that would cause or contribute to impairment of existing or designated uses under 314 CMR 4.05(5)(c), all applicants who apply for coverage under the 2022 CGP shall follow guidelines on fertilizer application, including use of fertilizer containing no phosphorus, in accordance with 330 CMR 31.00 Plant Nutrient Application Requirements for too Applicants shall follow EPA Method 180.1 to monitor for turbidity 101 Base Flood Elevation (BFE) is the elevation of surface water resulting from a flood that has a 1%chance of equaling or exceeding that level in any given year.The BFE is shown on the Flood Insurance Rate Map (FIRM) for zones AE,AH,A 1-A30,AR,AR/A,AR/AE,AR/Al-A30,AR/AH, AR/AO, V 1-V30 and V E. (Source: https://www.fema.gov/node/404233). Page 55 2022 Construction General Permit (CGP) Agricultural Land and Non-Agricultural Turf and Lawns. Further, fertilizer shall never be applied to a site when a rain event greater than 0.5 inches is forecast in the next 48 hours. L Pursuant to 314 CMR 3.11 (2)(a), all applicants who apply for coverage under the 2022 CGP and elect to carry out site inspections every 14 days shall also inspect sites within 24 hours of 0.25 inches of precipitation events or greater over 24 hours,or within 24 hours of a discharge that occurred due to snowmelt from 3.25 inches or greater of snow accumulation.102During the high flow periods in spring (i.e., months of April to June), inspection frequency shall be increased to once per week for all sites. L To determine whether 3.25 inches or greater of snow accumulation has occurred at a site, snowfall measurements can be taken at the site,103 or theoperator can rely on similar information from a local weather forecast. j. Implementing structural improvements, enhanced/resilient pollution prevention measures, and other mitigation measures can help to minimize impacts from stormwater discharges from major storm events such as hurricanes, storm surge, extreme/heavy precipitation,104and flood events. Pursuant to 314 CMR 3.11 (2)(a), if such stormwater control measures are already in place due to existing requirements mandated by other state, local or federal agencies, the SWPPP shall include a brief description of the controls and a reference to the existing requirement(s). If the site may be exposed to or has previously experienced such major storm events 105, additional stormwater control measures that may be considered, and implemented as necessary, include, but are not limited to: L Reinforce materials storage structures to withstand flooding and additional exertion of force; ii. Prevent floating of semi-stationary structures by elevating to the Base Flood Elevation (BFE) level or securing with non-corrosive device; HE, When a delivery of exposed materials is expected, and a storm is anticipated within 48 hours, delay delivery until after the storm or storematerials as appropriate (refer to emergency procedures); 102 This is the amount of snow that is equivalent to 0.25 inches of rain, based on information from the National Oceanic and Atmospheric Administration (NOAA) indicating that 13 inches of snow is, on average, equivalent to l inch of rain.See https://www.nssl.noaa.gov/education/svrwxl 01/winter/faq/. 103 NOAA's National Weather Service has guidelines on snowfall measurements at https://www.weather.gov/jkl/snow-measurement.These guidelines recommend use of a "snowboard" (a piece of wood about 16 inches by 16 inches) that is placed in an unobstructed part of the site on a hard surface. 104 Heavy precipitation refers to instances during which the amount of rain or snow experienced in a location substantially exceeds what is normal. What constitutes a period of heavy precipitation varies according to location and season. Heavy precipitation does not necessarily mean the total amount of precipitation at a location has increased—just that precipitation is occurring in more intense or more frequent events. 105 To determine if your facility is susceptible to an increased frequency of major storm events that could impact the discharge of pollutants in stormwater,you may reference FEMA, NOAA, or USGS flood map products at https://www.usgs.gov/faqs/where-can-i-find-flood-maps?qt- news_science_products=0#gtnews_science_products. Page 56 2022 Construction General Permit (CGP) iv. Temporarily store materials and waste above the Base Flood Elevation [EPA notes that it has deleted a footnote reference to the term "Base Flood Elevation"since the same footnote is already included in Part 9.1.2.g, above.] level; v. Temporarily reduce or eliminate outdoor storage; A Temporarily relocate any mobile vehicles and equipment to higher ground; AL Develop scenario-based emergency procedures for major storms that are complementary to regular stormwater pollution prevention planning andidentify emergency contacts for staff and contractors; and viii. Conduct staff training for implementing your emergency procedures atregular intervals. k. Pursuant to 314 CMR 3.11 (2)(a)6., and in accordance with MassDEP's obligation under 314 CMR 4.05(5)(e) to maintain surface waters free from pollutants in concentrations or combinations that are toxic to humans, aquatic life, or wildlife, permittees who seek coverage under the 2022 CGP and anticipate to carry out dust control shall limit their dust control methodology to using water only and specifically avoid using other techniques, such as solutions containing calcium chloride. I. If MassDEP requests a copy of the Stormwater Pollution Prevention Plan (SWPPP) for any construction site at any time, the permittee shall submit the SWPPP to MassDEP within 14 days of such a request. MassDEP may conduct an inspection of any site covered by this permit to ensure compliance with state lawrequirements, including state water quality standards. 9.1.3 MTR10F000 Areas in the State of Vermont located at a federal facility a. Earth disturbance at any one time is limited to five acres. b. All areas of earth disturbance must have temporary or final stabilization within 14 days of the initial disturbance. After this time, disturbed areas must be temporarily or permanently stabilized in advance of any runoff producing event. A runoff producing event is an event that produces runoff from the construction site. Temporary stabilization is not required if precipitation is not forecast and work is to continue in the next 24-hours or if the work is occurring in a self-contained excavation (i.e. no outlet) with a depth of two feet or greater (e.g. house foundation excavation, utility trenches). Areas of a construction site that drain to sediment basins are not considered eligible for this exemption, and the exemption applies only to the excavated area itself. c. Site inspections on active construction sites shall be conducted daily during the period from October 15 through April 15. d. The use of chemical treatments (e.g. polymers, flocculants, and coagulants) for the settling and/or removal of sediment from stormwater runoff associated with construction and construction-related activities requires prior written approval and an approved site and project-specific plan, from the Vermont Agency of Natural Resources. In addition, the use of cationic polymers is prohibited unless approved by the Vermont Agency of Natural Resources under a site and project-specific plan. e. Any applicant under EPA's CGP shall allow authorized Vermont Agency of Natural Resources representatives, at reasonable times and upon presentation of credentials, to enter upon the project site for purposes of inspecting the project and determining Page 57 2022 Construction General Permit (CGP) compliance with this Certification. f. The Vermont Agency of Natural Resources may reopen and alter or amend the conditions of this Certification over the life of the EPA 2022 Construction General Permit when such action is necessary to assure compliance with the VWQS. 9.2 EPA REGION 2 9.2.1 NYR101000 Indian country within the State of New York a.

Fond du Lac Reservation i. New dischargers wishing to discharge to an Outstanding Reservation Resource Water (ORRW)106must obtain an individual permit from EPA for storm water discharges from large and small construction activities. ii. A copy of the Storm Water Pollution Prevention Plan (SWPPP) must be submitted to the Office of Water Protection at least fifteen (15) days in advance of sending the Notice of Intent to EPA. The SWPPP can be submitted electronically to richardgitar@FDLREZ.com or by hardcopy sent to: Fond du Lac Reservation Office of Water Protection 1720 Big Lake Road Cloquet, MN 55720 HE, Copies of the Notice of Intent (NOI) and the Notice of Termination (NOT) must be sent to the Fond du Lac Office of Water Protection at the same time they are submitted to EPA. [The condition helps the Office of Water Protection keep track of when a project is about to start and when it has ended. FDL Water Quality Certification Ordinance, Section 204 (a) (2)). iv. If the project will entail a discharge to any watercourse or open water body, the turbidity limit shall NOT exceed 1 Oho of natural background within the receiving water(s) as determined by Office of Water Protection staff. For such discharges, turbidity sampling must take place within 24 hours of a 1/2-inch or greater rainfall event. The results of the sampling must be reported to the Office of Water Protection within 7 days of the sample collection. All sample reporting must include the date and time, location (GPS: UTM/Zone 15), and NTU. CGP applicants are encouraged to work with the Office of Water Protection in determining the most appropriate location(s) for sampling. [This condition helps both the Office of Water Protection and the project proponent in knowing whether or not their erosion control efforts are effective. FDL Water Quality Certification, Section 204 (b) (1)). v. Receiving waters with open water must be sampled for turbidity prior to any authorized discharge as determined by Office of Water Protection staff. This requirement only applies to receiving waters which no ambient turbidity data exists. [This condition allows the Office of Water Protection to obtain a baseline turbidity sample in which to compare to other samples. FDL Water Quality Certification Ordinance, Section 204 (b) (2)]. A All work shall be carried out in such a manner as will prevent violations of water quality criteria as stated in the Water Quality Standards of the Fond du Lac Reservation, Ordinance #12/98, as amended. This includes, but is not limited to, the prevention of any discharge that causes a condition in which visible solids, bottom deposits, or turbidity impairs the usefulness of water of the Fond du Lac 106 Although additional waters may be designated in the future, currently Perch Lake, Rice Portage Lake, Miller Lake, Deadfish Lake,and Jaskari Lake are designated as ORRWs. Page 62 2022 Construction General Permit (CGP) Reservation for any of the uses designated in the Water Quality Standards of the Fond du Lac Reservation. These uses include wildlife, aquatic life, warm water fisheries, cold water fisheries, subsistence fishing (netting), primary contact recreation, secondary contact recreation, cultural, wild rice areas, aesthetic waters, agriculture, navigation, commercial and wetlands. It also includes the designated uses of wetlands including, but not limited to, baseflow discharge, cultural opportunities, flood flow attenuation, groundwater recharge, indigenous floral and fauna) diversity and abundance, nutrient cycling, organic carbon export/cycling, protection of downstream water quality, recreation, resilience against climactic effects, sediment/shoreline stabilization, surface water storage, wild rice, and water dependent wildlife. [In addition to listing the designated uses of waters of the Fond du Lac Reservation, this condition also limits the project proponent to discharges that will not violate our Water Quality Standards. FDL Water Quality Certification Ordinance, Section 204 (a) (7)). VIL Appropriate steps shall be taken to ensure that petroleum products or other chemical pollutants are prevented from entering waters of the Fond du Lac Reservation. All spills must be reported to the appropriate emergency management Agency (National Response Center AND the State Duty Officer), and measures shall be taken immediately to prevent the pollution of waters of the Fond du Lac Reservation, including groundwater. The Fond du Lac Office of Water Protection must also be notified immediately of any spill regardless of size. [This condition helps protect water quality and also reminds project proponents of their responsibility in reporting spill events. FDL Water Quality Certification Ordinance, Section 204 (b) (3)). viii.All seed mixes, whether used for temporary stabilization or permanent seeding, shall NOT contain any annual ryegrass (Lolium species). Wild rye (Elymus species) or Oats (Avena species) may be used as a replacement in seed mixes. [This condition prevents the use of annual ryegrass on the Reservation. Annual ryegrass is allelopathic,which means it produces biochemical in its roots that inhibit the growth of native plants. If used in seed mixes, annual ryegrass could contribute to erosion, especially on slopes. However, the condition also specifies substitute grasses that germinate almost as fast as annual ryegrass for use as a cover crop to help prevent erosion. FDL Water Quality Certification Ordinance, Section 204 (t) (1))- ix. To prevent the introduction of invasive species, ALL contractors and subcontractors MUST disclose information stating prior equipment location(s) and ALL known invasive species potentially being transported from said location(s). All equipment MUST undergo a high pressure wash (including any equipment mats) BEFORE ENTERING the Fond du Lac Reservation. Personal equipment such as work boots, gloves, vest, etc. MUST be clean of debris, dirt and plant and animal material BEFORE ENTERING the Fond du Lac Reservation. Equipment being transported from known infested areas MUST undergo a high pressure wash as soon as possible after leaving the infested site and again BEFORE ENTERING the Fond du Lac Reservation, to avoid transport of invasive species into areas surrounding the Reservation. Written certification of equipment cleaning MUST be provided to the Fond du Lac Office of Water Protection. Upon arrival, ALL contractor and subcontractor equipment will be inspected by appointed Fond du Lac staff. If equipment is deemed unsatisfactory, the equipment MUST Page 63 2022 Construction General Permit (CGP) undergo a high pressure washing until the equipment is cleared by the inspector, until such time, minimal travel will be allowed through the Reservation. The contractor shall be held responsible for the control of any invasive species introduced as a result of their project. [This condition requires the project proponent to prevent the inadvertent introduction of invasive species by taking an active role in cleaning all vehicles, equipment, and equipment mats before entering the Reservation. This condition has been placed in certifications since 2012, due to the introduction of Wild Parsnip in 2011 from a pipeline contractor. It is much easier to prevent the introduction of an invasive species than it is to eradicate it once it has been introduced. Many invasive plant species form monocultures, preventing native plants from growing. This situation often leads to cases of erosion, which in turn effects water quality. FOL Water Quality Certification Ordinance, Section 204 (g) (1)]. x. A copy of this certification MUST be kept by the contractor on-site at all times and be available for viewing by all personnel, including inspectors. [This condition ensures that the information contained in the certification, especially the conditions, is readily available onsite for reference. FOL Water Quality Certification Ordinance, Section 204 (a) (9)]. b. The Grand Portage Band of Lake Superior Chippewa i. The CGP authorization is for construction activities that may occur within the exterior boundaries of the Grand Portage Reservation in accordance to the Grand Portage Land Use Ordinance.The CGP regulates stormwater discharges associated with construction sites of one acre or more in size. Only those activities specifically authorized by the CGP are authorized by this certification (the "Certification"). ii.

This requirement applies to discharges both during construction and after construction operations have been completed. The SWPPP must identify and document the rationale for selecting these BMPs and/or other controls. The SWPPP must also describe design specifications, construction specifications, maintenance schedules (including a long-term maintenance plan),criteria for inspections,and expected performance and longevity of these BMPs.For sites greater than 5 acres in size, BMP selection must be made based on the use of appropriatesoil loss prediction models (i.e. SEDCAD, RUSLE,SEDIMOT, MULTISED, etc.) OR equivalent genera IIyaccepted (by professional erosion control specialists) soil loss prediction tools. ii. For all sites, the Operator(s) must demonstrate, and include documentation in the SWPPP, that implementation of the site-specific practices will ensure that the applicable standards and TMDL WLAs are met, and will result in sediment yields and flow velocities that, to the maximum extent practicable,will not be greater than the sediment yield levels and flow velocities from preconstruction, pre- development conditions. HL All SWPPPs must be prepared in accordance with good engineering practices by qualified (e.g., CPESC certified, engineers with appropriate training) erosion control specialists familiar with the use of soil loss prediction models and design of erosion and sediment control systems based on these models (or equivalent soil Page 71 2022 Construction General Permit (CGP) loss prediction tools). Qualifications of the preparer (e.g., professional certifications, description of appropriate training) must be documented in the SWPPP.The Operator(s) must design, implement,and maintain BMPs in the manner specified in the SWPPP. NMED supports the use of EPA's small residential lot template if a site qualifies to use it as explained inthe permit, as long as it is consistent with the above requirements. NMED's requirement does not preclude small residential sites from using the template, but it may require an additional short paragraphto justify the selection of specific BMPs for the site. d.

Appendix C: EPA NOls and EPA NOTs C-1 Appendix C:EPA NOIs and EPA NOTs 2022 Construction General Permit (CGP) NPDES Form 6100-067 OMB No. 2040-0305, Exp. Date 01/31/25 Appendix D - Eligibility Worksheet Relating to Threatened and Endangered Species Protection D.1 Introduction This appendix provides a printable worksheet that can be helpful in selecting and documenting your eligibility criteria with respect to the protection of Federally listed threatened or endangered species and Federally designated "critical habitat" under the Endangered Species Act (ESA) [hereinafter "ESA-listed species and designated critical habitat(s)"] from discharges and discharge-related activities authorized under this permit. This is important because Section 9 of the ESA prohibits all persons and agencies from "taking" threatened and endangered species (16 U.S.C. § 1532(19)). While coordination between you and the U.S. Fish and Wildlife Service (USFWS) and/or the National Marine Fisheries Service (NMFS) (together, referred to as the "Services") may not be required in all cases, EPA encourages you to coordinate with the Services, to document that coordination, and to do so early in the planning process prior to submitting your NOI. D.2 Certifying ESA Eligibility Criterion for the CGP To be eligible for coverage under the CGP, you must certify that you meet one of the criteria listed in this worksheet (Section D.5), which is then submitted with your NOI for coverage under this permit. If you do not meet one of the ESA eligibility criteria outlined in the worksheet below, you are not eligible for coverage under this permit. These criteria ensure that coverage is available only for discharges and discharge-related activities that (1) avoid or eliminate any short- or long-term adverse effects to ESA-listed species and designated critical habitat(s), or (2) may result in any short- or long-term adverse effects that result in incidental take addressed under the incidental take statement of a biological opinion or permit for take issued under Section 10 of the ESA. As part of your determination of eligibility, EPA has developed a worksheet that assists operators in arriving at the correct criterion. The following requirements apply to the completion of the worksheet depending on how you are submitting your NOI for permit coverage: 1 . If the EPA Regional Office grants you a waiver from electronic reporting, in accordance with Part 1.1.5 of the CGP, you must complete the worksheet in section DA of this appendix to provide all information as required on your NOI that supports the eligibility criterion you qualify under per Part 1.1.5 of the permit. You must submit the worksheet with your NOI. If you do not submit the worksheet with your NOI, your NOI will be considered incomplete. 2. If you do not have a waiver from electronic reporting, you must complete your eligibility criteria selection outlined in the Endangered Species Protection section of the NOI in the NPDES eReporting Tool (NeT-CGP) and provide all information as required on your NOI that supports the eligibility criterion you qualify under per Part 1 .1.5 of the permit. The printable worksheet in this appendix may be helpful to you in preparing to submit your NOI, but you do not have to use it. D.3 What to Expect Once you Submit your NOI After you submit your NOI and before your NOI is authorized, EPA may notify you if any additional controls are necessary to ensure your discharges are not likely to result in any short- or long-term adverse effects on ESA-listed species and critical habitat. Page D-1 of 18 2022 Construction General Permit (CGP) The Services have the opportunity, within 14 days of submission of the NOI, to advise EPA whether either agency believes the planned discharges meet the selected eligibility criterion; whether the eligibility criterion could be met with additional conditions; or whether the eligibility criterion is not met. With respect to ESA issues, EPA recognizes the Services' expertise and will carefully consider their conclusion(s) in identifying eligibility for authorization, either with or without additional conditions. In the event EPA has placed a hold on your NOI based on NMFS or USFWS' recommendation, EPA will notify you as to whether your discharges are authorized or whether an individual permit will be required. If you do not hear from EPA within 14 days, you may assume that your discharge is authorized without further conditions. D.4 Worksheet Instructions Follow the instructions within the worksheet below to determine which criterion you are eligible for coverage under this permit. Check only 1 criterion, answer the required questions, and include the required information. Please keep the following in mind as you complete the worksheet: • The worksheet requires that you answer questions in a sequential order so that you can select the correct eligibility criterion. The worksheet does not go through each criterion alphabetically, but rather is organized in a way that allows you to eliminate those criteria that do not apply to your site. For instance, Step 1 of the worksheet requires you to determine whether criterion B, E, or F applies first, in that order, before proceeding to determining whether criterion A applies in Step 2. • You must consider ESA-listed species and/or designated critical habitat(s) under the jurisdiction of both the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS) and select the criterion that best applies to your site. You must comply with any applicable terms, conditions, or other requirements developed in theprocess of meeting one of the eligibility criteria in this section to remain eligible for coverage under this permit. • When evaluating the potential effects of your activities, you must consider effects to listed species or critical habitats within the "action area" of your construction activity, as identified by the USFWS IPaC and/or the NOAA website resources on page D-10 through D- 1 1 of this appendix. Please Note: NMFS'jurisdiction includes ESA-listed marine and estuarine species that spawn in inland rivers. The definition of "action area," which is contained in Appendix A, is repeated below forconvenience. "Action Area"—all areas to be affected directly or indirectly by the federal action and not merely theimmediate area involved in the action.See 50 CFR part 402.For the purposes of this permit and for application of the Endangered Species Act requirements,the following areas are included in the definition of action area: • The areas on the construction site where stormwater discharges originate and flow toward the point of discharge into the receiving waters.This includes: • areas on the construction site where excavation,site development,or other ground disturbance activities occur, and • areas where stormwater controls will be constructed and operated,including any areas where stormwater flows to and from the stormwater controls. • The areas in the vicinity of the construction site where stormwater discharges flow from the construction site to one or more points of discharge into receiving waters.(Example:Where stormwater flows into an off-site ditch,swale,or gully that leads to receiving waters.) • The extent of the receiving water potentially affected by stormwater discharges from your construction site through alteration of water chemistry,turbidity,temperature,or bank structure(i.e.,erosive flow),regardless of whether the construction site is adjacent to the receiving water. Page D-2 of 18 2022 Construction General Permit (CGP) D.5 Worksheet Instructions ➢ First determine whether you are eligible under Criterion B by reviewing the eligibility requirements below. ➢ If you determine that your facility does not meet Criterion B (e.g., due to difference in action area described, lack of analysis of appropriate effects, new listings or designation of critical habitat), proceed to check if you meet the requirements for Criterion E or F. Criterion B Eligibility Requirements If your discharges and discharge-related activities were already addressed in another operator's valid certification of eligibility under the current 2022 CGP that included your action area (e.g., a general contractor or developer may have completed and filed an NOI for the entire action area with the necessary ESA certifications (Criterion A, C, D, E, or F)), you may be eligible under Criterion B. In order to be eligible for coverage, you must confirm that all three of the following are true (check all that apply): ❑ I have confirmed that the other operator's certification of eligibility accounted for my action area and that the eligibility certification was valid. ❑ There has been no lapse of NPDES permit coverage in the other operator's certification. ❑ I will comply with all measures that formed the basis of the other operator's valid certification of eligibility. Instructions ➢ If all three of the above are true, you may check Criterion B below and answer questions B1-65, and if applicable, 1136-67. ➢ If any of the above are not true (for example, if there are any listed species in your action area that were not addressed in the other operator's certification, you are not eligible under Criterion B), you may not select Criterion B and must proceed to check if you meet the requirements for Criterion E or F. B Eligibility requirements met by another operator under the 2022 CGP. The construction site's discharges and discharge-related activities were already addressed in another operator's valid certification of eligibility for your "action area" under eligibility Criterion A, C, D, E, or F of the 2022 CGP and you have confirmed that no additional ESA-listed species and/or designated critical habitat under the jurisdiction of USFWS and/or NMFS not considered in the Page D-3 of 18 2022 Construction General Permit (CGP) that certification may be present or located in the "action area." To certify your eligibility under this criterion, there must be no lapse of NPDES permit coverage in the other CGP operator's certification. By certifying eligibility under this criterion, you agree to comply with any conditions upon which the other CGP operator's certification was based. You must include below the NPDES ID from the other 2022 CGP operator's notification of authorization under this permit and list any measures that you must comply with). If your certification is based on another 2022 CGP operator's certification under Criterion C, you must provide EPA with the relevant supporting information required of existing dischargers in Criterion C. B1. Provide the NPDES ID from the other CGP operator's NOI authorized under this permit: B2. Identify the eligibility criterion of the other CGP operator's NOI? (check only one) �A � C �'F]' D �[:]` E F B3. Provide the authorization date of the other CGP operator's NOI (MM/DD/YYYY): By certifying eligibility under Criterion B, you must comply with any terms and conditions imposed under the eligibility requirements of the criterion for which the other operator has established eligibility (either Criterion A, C, D, E, or F) to ensure that your discharges and discharge-related activities are protective of listed species and/or critical habitat. Note: If you are unable to meet these eligibility requirements, then you may either establish eligibility under one of the other criteria, or you may consider applying to EPA for an individual permit. B4. List any measures that formed the basis of the other operator's valid certification of eligibility that you will comply with (or enter "N/A" if none exist): B5. Check to confirm you have provided documentation in your SWPPP supporting your eligibility under Criterion B, including any of the terms and conditions, as well as the other operator's basis for establishing eligibility. Yes F-1 If your certification is based on another operator's certification under Criterion C, you must provide the following: Page D-4 of 18 2022 Construction General Permit (CGP) B6. What Federally listed species and/or designated habitat are located in your "action area"? (attached separate sheet if necessary) B7. What is the distance between your site and the listed species or designated critical habitat (in miles)-? Instructions If you selected Criterion B above and answered questions B1-B5, and if applicable, 1136-1137, you are done with this worksheet. If you are not filing electronically, you must submit this ON" ) worksheet with your NOI. If you are not eligible under Criterion B proceed to check if you meet the requirements for ;F Criterion E or F. Criterion E Eligibility Requirements If consultation under ESA section 7 has concluded, you may be eligible for coverage under Criterion E. In order to be eligible for coverage under Criterion E, you must confirm that both of the following are true (check all that apply): F-1 A consultation between a Federal agency and USFWS and/or the NMFS under section 7 of the ESA has concluded. Consultations can be either formal or informal, and would have occurred only as a result of a separate Federal action (e.g.,, during application for an individual wastewater discharge permit or the issuance of a wetlands dredge and fill permit), and the consultation must have addressed the effects of your construction activity's discharges and discharge-related activities on all ESA-listed threatened or endangered species and all designated critical habitat under the jurisdiction of each Service, as appropriate, in your action area. The result of this consultation must be either: i. A biological opinion currently in effect that determined that the action in question (taking into account the effects of your facility's discharges and discharge-related activities) is likely to adversely affect, but is not likely to jeopardize the continued existence of listed species or result in the destruction or adverse modification of critical habitat. The biological opinion must have included the effects of your facility's discharges' and discharge-related activities on all the listed species and designated Effects of discharge include, but are not limited to,the analysis of the hydrological, chemical, and biological effects of the discharge on listed species,their prey,and their habitat, as well as critical habitat,where designated. For example, the Page D-5 of 18 2022 Construction General Permit (CGP) critical habitat in your action area under the jurisdiction of each Service, as appropriate. To be eligible under (i), any reasonable and prudent measures specified in the incidental take statement must be implemented; ii. Written concurrence (e.g., letter of concurrence) from the applicable Service(s) with a determination that your facility's discharges and discharge-related activities are not likely to adversely affect ESA-listed species and/or designated critical habitat. The concurrence letter must have included the effects of your facility's discharges and discharge-related activities on all the ESA-listed species and/or designated critical habitat on your species list(s) acquired from USFWS and/or NMFS as part of this worksheet. F-1 The consultation does not warrant reinitiation under 50 CFR §402.16; or, if reinitiation of consultation is required (e.g., due to a new species listing, critical habitat designation, or new information), the Federal action agency has reinitiated the consultation and the result of the consultation is consistent with the statements above. Include any reinitiation documentation from the Services or consulting Federal agency with your NOI. Instructions ➢ If both of the above are true, you may cheek Criterion E below and answer questions E1-E6. • For more information on section 7 consultation, see 50 CFR part 402. If you receive a "jeopardy opinion," you may continue to work With USFWS and/or NMFS and your permitting authority to modify your project so that it will not jeopardize listed species or designated critical habitat. • Note that most consultations are accomplished through informal consultation. When conducting informal ESA section 7 consultation as a non-Federal representative, you must follow the procedure found in 50 CFR Part 402'of the ESA regulations. You must notify the Services of your intention and agreement to conduct consultation as a non-Federal representative. • Consultation may also occur in the context of another Federal ;action at the construction site (e.g., where ESA section 7 consultation was performed for issuance of a wetlands dredge and fill permit for the project or where a NEPA review is performed for the project that incorporates a section 7 consultation) • Any terms and conditions developed through consultations to protect listed,species and critical habitat must be incorporated into the SWPPP. As noted above, a Federal operator may, if they wish, initiate consultation with the Services at Step Four. Non-Federal operators may seek technical assistance from the Services at Step 5. • Whether ESA section 7 consultation must be performed with either USFWS, NMFS, or both Services depends on the listed species that may be affected by the operator's stormwater discharge. In general, NMFS has jurisdiction over marine, estuarine, and anadromous species. Operators should also be aware that while formal section 7 consultation 'provides protection from incidental takings liability, ;informal consultation does not. ➢ If not, proceed to check if you meet the requirements for Criterion F. effects analysis would have evaluated whether the various pollutants in the discharge (e.g.,TSS, metals) would adversely affect listed species through exposure to the pollutants,or to their prey or habitat. Effects that look only at short-term effects unrelated to the stormwater discharge effects to listed species are not sufficient for these purposes. Page D-6 of 18 2022 Construction General Permit (CGP) ❑ E ESA Section 7 consultation has successfully concluded. Consultation between a Federal Agency and the USFWS and/or NMFS under section 7 of the ESA has concluded. The consultation must have addressed the effects of the construction site's discharges and discharge-related activities on ESA-listed species and/or designated critical habitat under the jurisdiction of USFWS and/or NMFS. To certify eligibility under this criterion, Indicate the result of the consultation: ❑ Biological opinion and/or conference opinion and incidental take statement currently in effect currently in effect from USFWS and/or NMFS that concludes that the action in question (taking into account the effects of your site's discharges and discharge-related activities) is not likely to jeopardize the continued existence of ESA-listed species, nor the destruction or adverse modification of critical habitat; Or ❑ Written concurrence from USFWS and/or NMFS with a finding that the site's discharges and discharge-related activities are not likely to adversely affect ESA-listed species and/or designated critical habitat.

IN Instructions ➢ First, determine the extent of your action area. You must determine whether species listed as either threatened or endangered, or their critical habitat(s) are located in your site's action area (i.e., all areas to be affected directly or indirectly by the Federal action and not merely the immediate area involved in the action, including areas beyond the footprint of the site that are likely to be affected by stormwater discharges, discharge-related activities, and authorized non-stormwater discharges). You must consider the following in determining the action area for your site, and confirm that all the following are true: Fm_1 In determining my "action area", I have considered that discharges of pollutants from the project site can expand the action area well beyond the footprint of my site and the discharge point(s). I have taken into account the controls I will be implementing to minimize pollutants and the receiving waterbody characteristics (e.g., perennial, intermittent, ephemeral) in determining the extent of physical, chemical, and/or biotic effects of the Page D-9 of 18 2022 Construction General Permit (CGP) discharges. I confirm that all receiving waterbodies that could receive pollutants from my site are included in my action area. Fm-1 In determining my "action area", I have considered that discharge-related activities must also be accounted for in determining my action area. I understand that discharge-related activities are any activities that cause, contribute to, or result in stormwater and authorized non-stormwater point source discharges, and measures such as the siting, construction, timing,2 and operation of stormwater controls to control, reduce, or prevent pollutants from being discharged. I understand that any new or modified stormwater controls that will have noise or other similar effects, and any disturbances associated with construction of controls, are part of my action area. If you have any questions about determining the extent of your action area, you may contact EPA or the Services for assistance. https://www.epa.gov/npdes/contact-us- stormwater#regional Instructions ➢ Next, you must identify,to the best of your ability, any species listed as either threatened or endangered, or their critical habitat(s), that are located in your site's action area (see definitions of these terms in Appendix A). You must follow the instructions on the htti2s://www.ei2a.c o� v/npdes/construction-general-permit-threatened-and-endangered-species to obtain lists of any ESA-protected species and/or critical habitat that are expected to exist in your county, township, or the receiving water for your discharge. ➢ If ESA-protected resources occur within your action area, keep a copy of the species and critical habitat list(s) from the Service(s) with your SWPPP and use the lists) to complete your NOI. For USFWS species, attach to this worksheet the full printout from your IPaC query/Official Species List. You can include the map from your IPaC query.For NMFS species, attach to this worksheet the full printout of the report from your query of the mapping resource you used (either the National or Greater Atlantic Region Mapper). The printed report from NMFS mappers will include a map of your query. 2 Timing considerations could be related to,for example, a time of the year where a migratory bird species is present in the action area and the operator might want to consider that in terms of their construction sequencing; there are other times of the year where this consideration might not be relevant. Page D-10 of 18 2022 Construction General Permit (CGP) Instructions After completing Step 2 above, if there are no listed species and no critical habitat areas in your action area, you may be eligible for criterion A. Criterion A Eligibility Requirements In order to be eligible for coverage under criterion A, you must confirm that all the following are true (check all that apply): F-1 I confirm that I have used the species location resources of BOTH NMFS and USFWS to identify any ESA-listed species within my action area. F-1 I have confirmed there to be no ESA-listed species and no critical habitat in my action area. Instructions ➢ If all of the above are true,you may check criterion A below and answer questions Al-AS. ➢ If any of the above is not true, you may not select criterion A and must proceed to Step 3 to determine if you can become eligible under criterion C. Note: For existing dischargers that have previously obtained coverage under criterion A, you must verify whether ESA-protected species and/or critical habitat are expected to exist in your action area, as described above. Please note that if you now find that your action area overlaps with ESA-protected species or critical habitat, you must proceed to Step 3. F-1 A No ESA-listed species and/or designated critical habitat present in action area. You certify that ESA-listed species and designated critical habitat(s) under the jurisdiction of the USFWS or NMFS are not likely to occur in your site's "action area" as defined in Appendix A of this permit.. Please Note: NMFS'jurisdiction includes ESA-listed marine and estuarine species that spawn in inland rivers. Al. USFWS information sources used (reliance on State resources is not acceptable): Note: If your Official Species List from USFWS indicated no species or critical habitat were present in your action area, include the full consultation tracking code at the top of your Official Species List in your NOI in the basis statement for Criterion A. If an Official Species List was not available on IPaC, list the contact date and name of the Service staff with whom you corresponded to verify no USFWS species or critical habitat were present in your action area. Page D-11 of 18 2022 Construction General Permit (CGP) A2. NMFS information sources used (reliance on State resources is not acceptable): A3. I confirm that aerial image(s) of the site is attached. Yes ❑ A4. I confirm that a printout of the species' list(s) showing no ESA-listed species or critical habitat in my action area is attached. Yes ❑ AS. Check to confirm you have provided documentation in your SWPPP supporting your eligibility under Criterion A. For USFWS species, include the full printout from your IPaC query/Official Species List. You can include the map from your IPaC query. For NMFS species, include the full printout from the appropriate NMFS website resources on page X with the correct Region selected. Yes ❑ Instructions If you selected Criterion A above and answered questions Al-A5, you are done with this a worksheet. If you are not filing electronically,you must submit this worksheet with your NQI, y If listed species and/or critical habitat may exist in your action area, you must do one or more of the following: Conduct visual inspections. This method may be particularly suitable for construction sites that are smaller in size or located in non-natural settings such as highly urbanized areas or industrial parks where there is little or no natural habitat, or for construction activities that discharge directly into municipal stormwater collection systems. • Conduct a formal biological survey. In some cases, particularly for larger construction sites with extensive stormwater discharges, biological surveys may be an appropriate way to assess whether species are located in the action area and whether there are likely to be short- or long-term adverse effects to such species. Biological surveys are frequently performed by environmental consulting firms. • If required, conduct an environmental assessment under the National Environmental,Policy Act (NEPA). Some construction activities might require review under NEPA for specific reasons, such as Federal funding or other Federal involvement in the project. Note: Coverage under the CGP!does not trigger such a review for individual projects/sites. EPA has complied with NEPA in the issuance of the CGP. and • Follow the instructions in Steps 3—5 below, as applicable. Note that many but not all measures imposed to protect listed species under these steps will also protect critical habitat. Thus, meeting the eligibility requirements of this CGP may require measures to protect critical habitat that are''separate from those to protect listed species. Page D-12 of 18 2022 Construction General Permit (CGP) 04 Instructions ➢ If in Step 2 you identified that listed species and/or designated critical habitat could exist in your action area,you must next assess whether your discharges or discharge-related activities are likely to result in short- or long-term adverse effects to ESA-listed threatened or endangered species or designated critical habitat. Potential short- or long-term adverse effects from discharges and discharge-related activities include: • Hydrological. Stormwater discharges may cause siltation, sedimentation, or induce other changes in receiving waters such as temperature, salinity, or pH. These effects will vary with the amount of stormwater discharged and the volume and condition of the receiving water. Where a stormwater discharge constitutes a minute portion of the total volume of the receiving water, adverse hydrological effects are less likely. Construction activity itself may also alter drainage patterns on a site where construction occurs that can impact listed species or critical habitat. • Habitat. Excavation, site development, grading, and other surface disturbance activities from construction activities, including the installation or placement of stormwater controls, may result in adverse effects to listed species or their habitat. Stormwater may drain or inundate listed species habitat. • Toxicity. In some cases, pollutants in construction stormwater may have toxic effects on listed species. For example: Stormwater discharges from construction on or adjacent to agricultural property may contain pesticides. Stormwater discharges from projects involving pavement and roofing could include tar and asphalt. The scope of effects to consider will vary with each site. If you are having difficulty determining whether your project is likely to result in short- or long-term adverse effects to listed species or critical habitat, or one of the Services has already raised concerns to you, you should contact the appropriate Services office for assistance. Instructions v If any short- or long-term adverse effects to listed threatened or endangered species or their critical habitat are not likely,then you may check Criterion C below and answer questions � C1-C8. If any short- or long-term adverse effects to listed threatened or endangered species or their critical habitat are likely, you must follow Step 4 below. You may still be eligible for Criterion C if you are able to install and implement appropriate measures to avoid the likelihood of adverse effects. Page D-13 of 18 2022 Construction General Permit (CGP) Criterion C Eligibility Requirements FE-1C Discharges not likely to result in any short- or long-term adverse effects to ESA-listed species and/or designated critical habitat. ESA-listed species and/or designated critical habitat(s) under the jurisdiction of the USFWS and/or NMFS are likely to occur in or near your site's "action area," and you certify to EPA that your site's discharges and discharge-related activities are not likely to result in any short- or long-term adverse effects to ESA-listed threatened or endangered species and/or designated critical habitat. This certification may include consideration of any stormwater controls and/or management practices you will adopt to ensure that your discharges and discharge-related activities are not likely to result in any short- or long-term adverse effects to ESA-listed species and/or designated critical habitat. To certify your eligibility under this criterion, you must indicate belowl) the ESA-listed species and/or designated habitat located in your "action area" using the process outlined in this Appendix; 2) the distance between the site and the listed species and/or designated critical habitat in the action area (in miles); and 3) a rationale describing specifically how short- or long-term adverse effects to ESA-listed species will be avoided from the discharges and discharge-related activities. You must also include a copy of your site map from your SWPPP showing the upland and in-water extent of your "action area" with your NOI. C1.

General Tips for UsingThis Template This Dewatering Inspection Report Template is provided to assist you in preparing dewatering inspection reports for EPA's 2022 Construction General Permit (CGP). If you are covered under the 2022 CGP, you can use this template to create a dewatering inspection report form that complies with the minimum reporting requirements of Part 4.6.3 of the permit. Note that the use of this form is optional; you may use your own inspection report form provided it includes the minimum information required in Part 4.6.3 of the CGP. This template is for dewatering inspections only.A separate site inspection report template that does not include dewatering inspections and complies with the minimum reporting requirements of Part 4.7 of the permit is available at h,.�,. s: a v in s c instiruc,.i in n it I irirnit,.....ir sources,.....t Is,..... n m I tes. If you are covered under a State CGP, this template may be helpful in developing a report that can be used for that permit; however, it will need to be modified to meet the specific requirements of that permit. If your permitting authority requires you to use a specific inspection report form, you should not use this form. The following tips for using this template will help you ensure that the minimum permit requirements are met. > Review the inspection requirements. Before you start developing your inspection report form, read the CGP's Part 4 inspection requirements.This will ensure that you have a working understanding of the permit's underlying inspection requirements. > Complete all required blank fields. Fill out all blank fields. Only by filling out all fields will the template be compliant with the requirements of the permit. (Note: Where you do not need the number of rows provided in the template form for your inspection, you may delete these as you see fit. Or, if you need more space to document your findings,you may insert additional rows in the electronic version of this form or use the bottom of the page in the field version of this form.) > Use your site map to document inspection findings. In several places in the template, you are directed to specify the location of certain features of your site, including where stormwater controls are installed and where you will be stabilizing exposed soil.You are also asked to fill in location information for unsafe conditions and the locations of any discharges occurring during your inspections.Where you are asked for location information, EPA encourages you to reference the point on your SWPPP site map that corresponds to the requested location on the inspection form. Using the site map as a tool in this way will help you conduct efficient inspections, will assist you in evaluating problems found, and will ensure proper documentation. > Include the inspection form with your SWPPP. Once your form is complete, make sure to include a copy of the inspection form in your SWPPP in accordance with Part 7.2.7.e of the CGP. > Retain copies of all inspection reports with your records.You must also retain copies of all inspection reports in your records in accordance with the requirements in Part 4.7.3 of the CGP.These reports must be retained for at least 3 years from the date your permit coverage expires or is terminated in accordance with the requirements in Part 4.7.4 of the CGP. Instructions for Section A Inspector Name Enter the name of the person that conducted the inspection. Include the person's [enter] contact information (title,affiliated company name,address, email,and phone number). Inspection Date Enter the date you performed the inspection. [enter] Inspection Location If your project has multiple locations where you conduct separate dewatering [enter] inspections,specify the location where this inspection is being conducted.Otherwise, you can enter"dewatering operation." Discharge Start and End Times Enter the approximate time the dewatering discharge started and ended on the day of [enter] the inspection Rate of Discharge Enter the rate of discharge in gallons per day on the day of inspection. [enter] To estimate the approximate discharge rate on the day of dewatering inspection,one approach is to use the manufacturer's design pump rating for the pump model in use. For example,a pump rated at 164 gpm (gallons per minute) by the manufacturer can be assumed to be discharging at 164 gpm in most cases.To convert to gallons per day, multiply the rate in gpm by the ratio of minutes in one-day(1,440 minutes per day), resulting in a discharge rate of 236,160 gallons per day. In cases where the dewatering discharge is being pumped over long distances or a substantial distance uphill,which will result in a reduced pump rate relative to manufacturer's specification,the operator may improve the accuracy of the estimate by estimating the time required to fill a container of a known volume. For example, if it takes 60 seconds to fill an empty 55-gallon barrel,the estimated discharge rate is 55 gpm, or 79,200 gallons per day. Indicators of Pollutant Discharge For the point of discharge, describe any observed sediment plume, [enter] suspended solids, unusual color, presence of odor, decreased clarity, presence of foam;and or a visible sheen on the water surface or visible oily deposits on the bottom or shoreline of the receiving water. Corrective Action Required? Answer"Yes"if during your inspection you found any of the conditions listed above in the instructions for Yes ❑ the Indicators of Pollutant Discharge section.

Operator or "Duly Authorized Representative" — MANDATORY (CGP Appendix G Part G.11.2 and CGP Appendix H Section X) At a minimum, the dewatering inspection report must be signed by either (1) the person who signed the NOI, or (2) a duly authorized representative of that person. The following requirements apply: If the signatory will be the person who signed the NOI for permit coverage, as a reminder, that person must be one of the following types of individuals: For a corporation: By a responsible corporate officer. For the purpose of this subsection, a responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy- or decision-making functions for the corporation, or (ii) the manager of one or more manufacturing, production, or operating facilities, provided, the manager is authorized to make management decisions which govern the operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long term environmental compliance with environmental laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information for permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures. For a partnership or sole proprietorship: By a general partner or the proprietor, respectively. For a municipality, State, Federal, or other public agency: By either a principal executive officer or ranking elected official. For purposes of this subsection, a principal executive officer of a Federal agency includes (i) the chief executive officer of the agency, or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency (e.g., Regional Administrator of EPA). If the signatory will be a duly authorized representative, the following requirements must be met: The authorization is made in writing by the person who signed the NOI (see above); The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated facility or activity such as the position of plant manager, operator of a well or a well field, superintendent, position of equivalent responsibility, or an individual or position having overall responsibility for environmental matters for the company. (A duly authorized representative may thus be either a named individual or any individual occupying a named position); and The signed and dated written authorization is included in the SWPPP.A copy must be submitted to EPA, if requested. Sign, date and print your name and affiliation. Contractor or Subcontractor - OPTIONAL Where you rely on a contractor or subcontractor to complete the dewatering inspection report,you should consider requiring the individual(s) to sign and certify each report. Note that this does not relieve you, the permitted operator, of the requirement to sign and certify the dewatering inspection report as well. If applicable, sign, date, and print your name and affiliation. Note While EPA has made every effort to ensure the accuracy of all instructions contained in this template, it is the permit, not this template, that determines the actual obligations of regulated construction stormwater discharges. In the event of a conflict between this template and any corresponding provision of the CGP, you must abide by the requirements in the permit.

Appendix K: EndangeredSpecies Documentation K-1 Appendix K:Endangered Species Documentation 2022 Construction General Permit (CGP) NPDES Farm 1 7 OMB No., 24 3 5, Exp. Date 1. 3 2 Appendix D - Eligibility Worksheet Relating to Threatened and Endangered Species Protection D.1 Introduction This appendix provides a printable worksheet that can be helpful in selecting and documenting your eligibility criteria with respect to the protection of Federally listed threatened or endangered species and Federally designated "critical habitat" under the Endangered Species Act (ESA) [hereinafter "ESA-listed species and designated critical habitat(s)"] from discharges and discharge-related activities authorized under this permit. This is important because Section 9 of the ESA prohibits all persons and agencies from "taking" threatened and endangered species (16 U.S.C. § 1532(19)). While coordination between you and the U.S. Fish and Wildlife Service (USFWS) and/or the National Marine Fisheries Service (NMFS) (together, referred to as the "Services") may not be required in all cases, EPA encourages you to coordinate with the Services, to document that coordination, and to do so early in the planning process prior to submitting your NOI. D.2 Certifying ESA Eligibility Criterion for the CGP To be eligible for coverage under the CGP, you must certify that you meet one of the criteria listed in this worksheet (Section D.5), which is then submitted with your NOI for coverage under this permit. If you do not meet one of the ESA eligibility criteria outlined in the worksheet below, you are not eligible for coverage under this permit. These criteria ensure that coverage is available only for discharges and discharge-related activities that (1) avoid or eliminate any short- or long-term adverse effects to ESA-listed species and designated critical habitat(s), or (2) may result in any short- or long-term adverse effects that result in incidental take addressed under the incidental take statement of a biological opinion or permit for take issued under Section 10 of the ESA. As part of your determination of eligibility, EPA has developed a worksheet that assists operators in arriving at the correct criterion. The following requirements apply to the completion of the worksheet depending on how you are submitting your NOI for permit coverage: 1 . If the EPA Regional Office grants you a waiver from electronic reporting, in accordance with Part 1.1.5 of the CGP, you must complete the worksheet in section DA of this appendix to provide all information as required on your NOI that supports the eligibility criterion you qualify under per Part 1.1.5 of the permit. You must submit the worksheet with your NOI. If you do not submit the worksheet with your NOI, your NOI will be considered incomplete. 2. If you do not have a waiver from electronic reporting, you must complete your eligibility criteria selection outlined in the Endangered Species Protection section of the NOI in the NPDES eReporting Tool (NeT-CGP) and provide all information as required on your NOI that supports the eligibility criterion you qualify under per Part 1 .1.5 of the permit. The printable worksheet in this appendix may be helpful to you in preparing to submit your NOI, but you do not have to use it. D.3 What to Expect Once you Submit your NOI After you submit your NOI and before your NOI is authorized, EPA may notify you if any additional controls are necessary to ensure your discharges are not likely to result in any short- or long-term adverse effects on ESA-listed species and critical habitat. Page D-1 of 18 2022 Construction General Permit (CGP) The Services have the opportunity, within 14 days of submission of the NOI, to advise EPA whether either agency believes the planned discharges meet the selected eligibility criterion; whether the eligibility criterion could be met with additional conditions; or whether the eligibility criterion is not met. With respect to ESA issues, EPA recognizes the Services' expertise and will carefully consider their conclusion(s) in identifying eligibility for authorization, either with or without additional conditions. In the event EPA has placed a hold on your NOI based on NMFS or USFWS' recommendation, EPA will notify you as to whether your discharges are authorized or whether an individual permit will be required. If you do not hear from EPA within 14 days, you may assume that your discharge is authorized without further conditions. D.4 Worksheet Instructions Follow the instructions within the worksheet below to determine which criterion you are eligible for coverage under this permit. Check only 1 criterion, answer the required questions, and include the required information. Please keep the following in mind as you complete the worksheet: • The worksheet requires that you answer questions in a sequential order so that you can select the correct eligibility criterion. The worksheet does not go through each criterion alphabetically, but rather is organized in a way that allows you to eliminate those criteria that do not apply to your site. For instance, Step 1 of the worksheet requires you to determine whether criterion B, E, or F applies first, in that order, before proceeding to determining whether criterion A applies in Step 2. • You must consider ESA-listed species and/or designated critical habitat(s) under the jurisdiction of both the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS) and select the criterion that best applies to your site. You must comply with any applicable terms, conditions, or other requirements developed in theprocess of meeting one of the eligibility criteria in this section to remain eligible for coverage under this permit. • When evaluating the potential effects of your activities, you must consider effects to listed species or critical habitats within the "action area" of your construction activity, as identified by the USFWS IPaC and/or the NOAA website resources on page D-10 through D- 1 1 of this appendix. Please Note: NMFS'jurisdiction includes ESA-listed marine and estuarine species that spawn in inland rivers. The definition of "action area," which is contained in Appendix A, is repeated below forconvenience. "Action Area"—all areas to be affected directly or indirectly by the federal action and not merely theimmediate area involved in the action.See 50 CFR part 402.For the purposes of this permit and for application of the Endangered Species Act requirements,the following areas are included in the definition of action area: • The areas on the construction site where stormwater discharges originate and flow toward the point of discharge into the receiving waters.This includes: • areas on the construction site where excavation,site development,or other ground disturbance activities occur, and • areas where stormwater controls will be constructed and operated,including any areas where stormwater flows to and from the stormwater controls. • The areas in the vicinity of the construction site where stormwater discharges flow from the construction site to one or more points of discharge into receiving waters.(Example:Where stormwater flows into an off-site ditch,swale,or gully that leads to receiving waters.) • The extent of the receiving water potentially affected by stormwater discharges from your construction site through alteration of water chemistry,turbidity,temperature,or bank structure(i.e.,erosive flow),regardless of whether the construction site is adjacent to the receiving water. Page D-2 of 18 2022 Construction General Permit (CGP) D.5 Worksheet Instructions ➢ First determine whether you are eligible under Criterion B by reviewing the eligibility requirements below. ➢ If you determine that your facility does not meet Criterion B (e.g., due to difference in action area described, lack of analysis of appropriate effects, new listings or designation of critical habitat), proceed to check if you meet the requirements for Criterion E or F. Criterion B Eligibility Requirements If your discharges and discharge-related activities were already addressed in another operator's valid certification of eligibility under the current 2022 CGP that included your action area (e.g., a general contractor or developer may have completed and filed an NOI for the entire action area with the necessary ESA certifications (Criterion A, C, D, E, or F)), you may be eligible under Criterion B. In order to be eligible for coverage, you must confirm that all three of the following are true (check all that apply): ❑ I have confirmed that the other operator's certification of eligibility accounted for my action area and that the eligibility certification was valid. ❑ There has been no lapse of NPDES permit coverage in the other operator's certification. ❑ I will comply with all measures that formed the basis of the other operator's valid certification of eligibility. Instructions ➢ If all three of the above are true, you may check Criterion B below and answer questions B1-65, and if applicable, 1136-67. Is, ➢ If any of the above are not true (for example, if there are any listed species in your action area that were not addressed in the other operator's certification, you are not eligible under Criterion ION B), you may not select Criterion B and must proceed to check if you meet the requirements for Criterion E or F. B Eligibility requirements met by another operator under the 2022 CGP. The construction site's discharges and discharge-related activities were already addressed in another operator's valid certification of eligibility for your "action area" under eligibility Criterion A, C, D, E, or F of the 2022 CGP and you have confirmed that no additional ESA-listed species and/or designated critical habitat under the jurisdiction of USFWS and/or NMFS not considered in the Page D-3 of 18 2022 Construction General Permit (CGP) that certification may be present or located in the "action area." To certify your eligibility under this criterion, there must be no lapse of NPDES permit coverage in the other CGP operator's certification. By certifying eligibility under this criterion, you agree to comply with any conditions upon which the other CGP operator's certification was based. You must include below the NPDES ID from the other 2022 CGP operator's notification of authorization under this permit and list any measures that you must comply with). If your certification is based on another 2022 CGP operator's certification under Criterion C, you must provide EPA with the relevant supporting information required of existing dischargers in Criterion C.

If you are not filing electronically, you must submit this worksheet with your NOI. If you are not eligible under Criterion B proceed to check if you meet the requirements for Criterion E or F. Criterion E Eligibility Requirements If consultation under ESA section 7 has concluded, you may be eligible for coverage under Criterion E. In order to be eligible for coverage under Criterion E. you must confirm that both of the following are true (check all that apply): F-1 A consultation between a Federal agency and USFWS and/or the NMFS under section 7 of the ESA has concluded. Consultations can be either formal or informal, and would have occurred only as a result of a separate Federal action (e.g.,, during application for an individual wastewater discharge permit or the issuance of a wetlands dredge and fill permit), and the consultation must have addressed the effects of your construction activity's discharges and discharge-related activities on all ESA-listed threatened or endangered species and all designated critical habitat under the jurisdiction of each Service, as appropriate, in your action area. The result of this consultation must be either: i. A biological opinion currently in effect that determined that the action in question (taking into account the effects of your facility's discharges and discharge-related activities) is likely to adversely affect, but is not likely to jeopardize the continued existence of listed species or result in the destruction or adverse modification of critical habitat. The biological opinion must have included the effects of your facility's discharges' and discharge-related activities on all the listed species and designated Effects of discharge include, but are not limited to,the analysis of the hydrological, chemical, and biological effects of the discharge on listed species,their prey,and their habitat, as well as critical habitat,where designated. For example, the Page D-5 of 18 2022 Construction General Permit (CGP) critical habitat in your action area under the jurisdiction of each Service, as appropriate. To be eligible under (i), any reasonable and prudent measures specified in the incidental take statement must be implemented; ii. Written concurrence (e.g., letter of concurrence) from the applicable Service(s) with a determination that your facility's discharges and discharge-related activities are not likely to adversely affect ESA-listed species and/or designated critical habitat. The concurrence letter must have included the effects of your facility's discharges and discharge-related activities on all the ESA-listed species and/or designated critical habitat on your species list(s) acquired from USFWS and/or NMFS as part of this worksheet. F-1 The consultation does not warrant reinitiation under 50 CFR §402.16; or, if reinitiation of consultation is required (e.g., due to a new species listing, critical habitat designation, or new information), the Federal action agency has reinitiated the consultation and the result of the consultation is consistent with the statements above. Include any reinitiation documentation from the Services or consulting Federal agency with your NOI. Instructions ➢ If both of the above are true, you may cheek Criterion E below and answer questions Is E1-E6. • For more information on section 7 consultation, see 50 CFR part 402. If you receive a "jeopardy opinion," you may continue to work with USFWS and/or NMFS and your permitting authority to modify your project so that it will not jeopardize listed species or designated critical habitat. • Note that most consultations are accomplished through informal consultation. When conducting informal ESA section 7 consultation as a non-Federal representative, you must follow the procedure found in 50 CFR Part 402 of the ESA regulations. You must notify the Services of your intention and agreement to conduct consultation as a non-Federal representative. • Consultation may also occur in the context of another Federal action at the construction site (e.g., where ESA section 7 consultation was performed for issuance of a wetlands dredge and fill permit for the project or where a NEPA review is performed for the project that incorporates a section 7 consultation) • Any terms and conditions developed through consultations to protect listed species and critical habitat must be incorporated into the SWPPP.As noted above, a Federal operator may, if they wish, initiate consultation with the Services at Step Four. Non-Federal operators may seek technical assistance from the Services at Step 5. • Whether ESA section 7 consultation must be performed with either USFWS, NMFS, or both Services depends on the listed species that may be affected by the operator's stormwater discharge. In general NMFS has jurisdiction over marine, estuarine, and anadromous species. Operators should also be aware that while formal section 7 consultation provides protection from incidental takings liability, ;informal consultation does not. ➢ If not, proceed to check if you meet the requirements for Criterion F. effects analysis would have evaluated whether the various pollutants in the discharge (e.g.,TSS, metals) would adversely affect listed species through exposure to the pollutants,or to their prey or habitat. Effects that look only at short-term effects unrelated to the stormwater discharge effects to listed species are not sufficient for these purposes. Page D-6 of 18 2022 Construction General Permit (CGP) ❑ E ESA Section 7 consultation has successfully concluded. Consultation between a Federal Agency and the USFWS and/or NMFS under section 7 of the ESA has concluded.

If you are not filing electronically, you must submit this worksheet with your NOI. �= If you are not eligible under Criterion F, proceed to Step 2. Instructions ➢ First, determine the extent of your action area. You must determine whether species listed as either threatened or endangered, or their critical habitat(s) are located in your site's action area (i.e., all areas to be affected directly or indirectly by the Federal action and not merely the immediate area involved in the action, including areas beyond the footprint of the site that are likely to be affected by stormwater discharges, discharge-related activities, and authorized non-stormwater discharges). You must consider the following in determining the action area for your site, and confirm that all the following are true: ❑ In determining my "action area", I have considered that discharges of pollutants from the project site can expand the action area well beyond the footprint of my site and the discharge point(s). I have taken into account the controls I will be implementing to minimize pollutants and the receiving waterbody characteristics (e.g., perennial, intermittent, ephemeral) in determining the extent of physical, chemical, and/or biotic effects of the Page D-9 of 18 2022 Construction General Permit (CGP) discharges. I confirm that all receiving waterbodies that could receive pollutants from my site are included in my action area. F-1 In determining my "action area", I have considered that discharge-related activities must also be accounted for in determining my action area. I understand that discharge-related activities are any activities that cause, contribute to, or result in stormwater and authorized non-stormwater point source discharges, and measures such as the siting, construction, timing,2 and operation of stormwater controls to control, reduce, or prevent pollutants from being discharged. I understand that any new or modified stormwater controls that will have noise or other similar effects, and any disturbances associated with construction of controls, are part of my action area. If you have any questions about determining the extent of your action area, you may contact EPA or the Services for assistance. https://www.epa.gov/npdes/contact-us- stormwater#regional Instructions ➢ Next, you must identify,to the best of your ability, any species listed as either threatened or endangered, or their critical habitat(s), that are located in your site's action area (see definitions of these terms in Appendix A). You must follow the instructions on the https://www.epa.c o� v/npdes/construction-general-permit-threatened-and-endangered-species to obtain lists of any ESA-protected species and/or critical habitat that are expected to exist in your county, township, or the receiving water for your discharge. ➢ If ESA-protected resources occur within your action area, keep a copy of the species and critical habitat list(s) from the Service(s) with your SWPPP and use the list(s) to complete your NOI. For USFWS species, attach to this worksheet the full printout from your IPaC query/Official Species List. You can include the map from your IPaC query.For NMFS species, attach to this worksheet the full printout of the report from your query of the mapping resource you used (either the National or Greater Atlantic Region Mapper). The printed report from NMFS mappers will include a map of your query. 2 Timing considerations could be related to,for example, a time of the year where a migratory bird species is present in the action area and the operator might want to consider that in terms of their construction sequencing; there are other times of the year where this consideration might not be relevant. Page D-10 of 18 2022 Construction General Permit (CGP) Instructions After completing Step 2 above, if there are no listed species and no critical habitat areas in your action area, you may be eligible for criterion A. Criterion A Eligibility Requirements In order to be eligible for coverage under criterion A, you must confirm that all the following are true (check all that apply): F-1 I confirm that I have used the species location resources of BOTH NMFS and USFWS to identify any ESA-listed species within my action area. F-1 I have confirmed there to be no ESA-listed species and no critical habitat in my action area. Instructions ➢ If all of the above are true,you may check criterion A below and answer questions Al-AS. is" ➢ If any of the above is not true, you may not select criterion A and must proceed to Step 3 to determine if you can become eligible under criterion C. Note: For existing dischargers that have previously obtained coverage under criterion A, you must verify whether ESA-protected species and/or critical habitat are expected to exist in your action area, as described above. Please note that if you now find that your action area overlaps with ESA-protected species or critical habitat, you must proceed to Step 3. F-1 A No ESA-listed species and/or designated critical habitat present in action area. You certify that ESA-listed species and designated critical habitat(s) under the jurisdiction of the USFWS or NMFS are not likely to occur in your site's "action area" as defined in Appendix A of this permit.. Please Note: NMFS'jurisdiction includes ESA-listed marine and estuarine species that spawn in inland rivers. Al. USFWS information sources used (reliance on State resources is not acceptable): Note: If your Official Species List from USFWS indicated no species or critical habitat were present in your action area, include the full consultation tracking code at the top of your Official Species List in your NOI in the basis statement for Criterion A. If an Official Species List was not available on IPaC, list the contact date and name of the Service staff with whom you corresponded to verify no USFWS species or critical habitat were present in your action area. Page D-11 of 18 2022 Construction General Permit (CGP) A2. NMFS information sources used (reliance on State resources is not acceptable): A3. I confirm that aerial image(s) of the site is attached. Yes ❑ A4. I confirm that a printout of the species' list(s) showing no ESA-listed species or critical habitat in my action area is attached. Yes ❑ AS. Check to confirm you have provided documentation in your SWPPP supporting your eligibility under Criterion A. For USFWS species, include the full printout from your IPaC query/Official Species List. You can include the map from your IPaC query. For NMFS species, include the full printout from the appropriate NMFS website resources on page X with the correct Region selected. Yes ❑ Instructions If you selected Criterion A above and answered questions Al-A5,you are done with this works'heet. If you are not filing electronically,you must submit this workshee't with your NQI, y If listed species and/or critical habitat may exist in your action area, you must do one or more of the following Conduct visual inspections. This method may be particularly suitable for construction sites that are smaller in size or located in non-natural settings such as highly urbanized areas or industrial parks where there is little or no natural habitat,or for construction activities that discharge directly into municipal stormwater collection systems. • Conduct a formal biological survey. In some cases, particularly for larger construction sites with extensive stormwater discharges, biological surveys may be an appropriate way to assess whether species are located in the action area and whether there are likely to be short- or long-term adverse effects to such species. Biological surveys are frequently performed by environmental consulting firms. • If required, conduct an environmental assessment under the National Environmental Policy Act (NEPA). Some construction activities might require review under NEPA for specific reasons, such as Federal funding or other Federal involvement in the project. Note: Coverage under the CGP!does not;trigger such a review for individual projects/sites. EPA has complied with NEPA in the issuance of the CGP. and • Follow the instructions in Steps 3-5 below, as applicable. Note that many but not all measures imposed to protect listed species under these steps will also protect critical habitat. Thus, meeting the eligibility requirements of this CGP may require measures to protect critical habitat that are''separate from those to protect listed species. Page D-12 of 18 2022 Construction General Permit (CGP) MID WIN 5 MO Instructions ➢ If in Step 2 you identified that listed species and/or designated critical habitat could exist in your action area,you must next assess whether your discharges or discharge-related activities are likely to result in short- or long-term adverse effects to ESA-listed threatened or endangered species or designated critical habitat. Potential short- or long-term adverse effects from discharges and discharge-related activities include: • Hydrological. Stormwater discharges may cause siltation, sedimentation, or induce other changes in receiving waters such as temperature, salinity, or pH. These effects will vary with the amount of stormwater discharged and the volume and condition of the receiving water. Where a stormwater discharge constitutes a minute portion of the total volume of the receiving water, adverse hydrological effects are less likely. Construction activity itself may also alter drainage patterns on a site where construction occurs that can impact listed species or critical habitat. • Habitat. Excavation, site development, grading, and other surface disturbance activities from construction activities, including the installation or placement of stormwater controls, may result in adverse effects to listed species or their habitat. Stormwater may drain or inundate listed species habitat. • Toxicity. In some cases, pollutants in construction stormwater may have toxic effects on listed species. For example: Stormwater discharges from construction on or adjacent to agricultural property may contain pesticides. Stormwater discharges from projects involving pavement and roofing could include tar and asphalt. The scope of effects to consider will vary with each site. If you are having difficulty determining whether your project is likely to result in short- or long-term adverse effects to listed species or critical habitat, or one of the Services has already raised concerns to you, you should contact the appropriate Services office for assistance. Instructions v If any short- or long-term adverse effects to listed threatened or endangered species or their critical habitat are not likely,then you may check Criterion C below and answer questions C1-C8. If any short- or long-term adverse effects to listed threatened or endangered species or their critical habitat are likely, you must follow Step 4 below. You may still be eligible for Criterion C if you are able to install and implement appropriate measures to avoid the likelihood of adverse effects. Page D-13 of 18 2022 Construction General Permit (CGP) Criterion C Eligibility Requirements ❑ C Discharges not likely to result in any short- or long-term adverse effects to ESA-listed species and/or designated critical habitat. ESA-listed species and/or designated critical habitat(s) under the jurisdiction of the USFWS and/or NMFS are likely to occur in or near your site's "action area," and you certify to EPA that your site's discharges and discharge-related activities are not likely to result in any short- or long-term adverse effects to ESA-listed threatened or endangered species and/or designated critical habitat. This certification may include consideration of any stormwater controls and/or management practices you will adopt to ensure that your discharges and discharge-related activities are not likely to result in any short- or long-term adverse effects to ESA-listed species and/or designated critical habitat. To certify your eligibility under this criterion, you must indicate belowl) the ESA-listed species and/or designated habitat located in your "action area" using the process outlined in this Appendix; 2) the distance between the site and the listed species and/or designated critical habitat in the action area (in miles); and 3) a rationale describing specifically how short- or long-term adverse effects to ESA-listed species will be avoided from the discharges and discharge-related activities.

About Official Species Lists The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Federal and non-Federal project proponents have responsibilities under the Act to consider effects on listed species. The enclosed species list identifies threatened, endangered, proposed, and candidate species, as well as proposed and final designated critical habitat, that may occur within the boundary of your proposed project and/or may be affected by your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. The Service recommends that verification be completed by visiting the IPaC website at regular intervals during project planning and implementation for updates to species lists and information.An updated list may be requested by returning to an existing project's page in IPaC. Endangered Species Act Project Review Please visit the "New England Field Office Endangered Species Project Review and Consultation"website for step-by-step instructions on how to consider effects on listed species and prepare and submit a project review package if necessary: https://www.fws.gov/office/new-england-ecological-services/endangered-species-proj ect-review *NOTE* Please do not use the Consultation Package Builder tool in IPaC except in specific situations following coordination with our office. Please follow the project review guidance on our website instead and reference your Project Code in all correspondence. Northern Long-eared Bat - (Updated i.' ° "" ) The Service published a final rule to reclassify the northern long-eared bat (NLEB) as endangered on November 30, 2022. The final rule went into effect on March 31, 2023. You may utilize the Northern Long-eared Bat Rangewide Determination Key available in IPaC. More information about this Determination Key and the Interim Consultation Framework are available on the northern long-eared bat species page: https://www.fws. ov/species/northern-long-eared-bat-myotis-septentrionalis For projects that previously utilized the 4(d) Determination Key, the change in the species' status may trigger the need to re-initiate consultation for any actions that are not completed and for which the Federal action agency retains discretion once the new listing determination becomes effective. If your project was not completed by March 31, 2023, and may result in incidental take of NLEB, please reach out to our office at newengland@fws.gov to see if reinitiation is necessary. Additional Info About Section 7 of the Act Under section 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to determine whether projects may affect threatened and endangered species and/or designated critical habitat. If a Federal agency, or its non-Federal representative, determines that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Federal agency also may need to consider proposed species and proposed critical habitat in the consultation. 50 CFR 402.14(c)(1) specifies the information required for consultation under the Act regardless of the format of the evaluation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: https://www.fws.gov/service/section-7-consultations In addition to consultation requirements under Section 7(a)(2) of the ESA, please note that under sections 7(a)(1) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species. Please contact NEFO if you would like more information. Candidate species that appear on the enclosed species list have no current protections under the ESA. The species' occurrence on an official species list does not convey a requirement to 2 of... consider impacts to this species as you would a proposed, threatened, or endangered species. The ESA does not provide for interagency consultations on candidate species under section 7, however, the Service recommends that all project proponents incorporate measures into projects to benefit candidate species and their habitats wherever possible. Migratory Birds In addition to responsibilities to protect threatened and endangered species under the Endangered Species Act (ESA), there are additional responsibilities under the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to protect native birds from project-related impacts.Any activity, intentional or unintentional, resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more information regarding these Acts see: https://www.fws.gov/program/migratory-bird-permit -bird-permit https://www.fws.gov/library/collections/bald-and-golden-eagle-management Please feel free to contact us at newengland@fws.gov with your Project Code in the subject line if you need more information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat.

You may only register one UIC Class V"well category" and "well type" combination with each BRP WS06 application. If your residence or facility includes multiple combinations of"well category" and "well type"then you must submit a separate BRP WS06 application with applicable payment transmittal form and fee for each unique combination. The requirement for separate applications applies whether for multiple single use wells or a single well that is used for more than one type of UIC Class V wastewater discharge. If your application is for the conversion of a well that was not previously registered then you must submit two (2) separate BRP WS06 applications (with 2 separate payment transmittal forms) and pay the fees associated with each registration application. One application must be submitted for the proposed converted new use and one for the closure or partial closure of the unregistered well use. In addition to the above UIC registration requirements, applicants should consider the need to obtain the following permits or sanctions that may apply: • Wetlands requirements should be checked through the local Conservation Commission; 0 Ground Water Discharge Permit Program (314 CMR 5.00 b,, limn .. v / ii cliff e /limn e iir/lire u tlii iir / 1 limn iir 15�-00 it u in iir Id iisc iir e�� iirii iiistii ; • A MassDEP Title 5 Permit (310 CMR 15.00 / limn s o e,,,,,,,�„/ in lii,,,,,,,s/limns e t iir/iire u tliioii 1 ,cirn iir,15 100 ,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, • Local Board of Health requirements may also apply; and, • Local Plumbing Inspector requirements.

Additional Well-Type-Specific Information Sto rmwate r Well Does the overflow from the UIC well(s) discharge to groundwater onto a different property or to a stormwater system that is owned/operated by another entity? Check the "yes" box if the overflow is connected to a groundwater discharge well or to a stormwater system that is not owned by the same entity that owns the property for which the UIC stormwater discharge registration is being sought. If you checked the "yes" box for this question then you must attach a copy of the approval letter, permit, or Order of Conditions from the entity that owns the property that is receiving the overflow water or from the entity that controls the municipal stormwater system or from the local conservation commission (whichever is applicable). Does the overflow from the UIC well(s) discharge to surface water or within a wetland or surface water buffer on-site or off-site? Check the applicable "yes" or"no" box. If you checked the "yes" box for this question then you must attach the Order of Conditions from the local conservation commission. L. Injection Well(s) or Activity(ies) Being Closed Is the closure being required by a federal, state, or local entity? Check the "yes" box if the proposed closure is the result of a written notification by a federal, state, or local authority indicating that the well(s) must be closed. If you check off the "yes" box fill out the information requested to identify the issuing authority and any contact information that was provided to you for that authority. Number of Wells Being Closed with this Application: Enter the number of stormwater discharge wells that will be completely closed that are associated with this UIC registration application or with the existing UIC registration number that was previously assigned by MassDEP. Completely closed means that all entry points associated with the stormwater discharge will no longer discharge to the well(s) after the proposed closure activities have been completed. If you are only closing some but not all of the stormwater entry points for a particular UIC well then you are only closing some of the entry points and not the well itself. Do not include in your answer any wells for which one or more stormwater entry points will continue to discharge to the well following the completion of the proposed closure activities. Closure of a UIC well does not necessarily mean that the well itself will be physically decommissioned. Under many circumstances a well that is closed as a UIC well for one "well category" and "well type" may continue to be Stormins.doc rev.08/13 Page 13 of 16 Massachusetts Department of Environmental Protection Bureau of Resource Protection — Drinking Water Program BRP WS 06 UIC Registration Stormwater Discharge Well Instructions and Supporting Materials used for other types of UIC and/or non-UIC type uses. However, if the well will not be used for any other water supply or water discharge purposes it is considered an abandoned well per 310 CMR 46.00 ii................................................................................ s.................... ee cs e s iir l ce/lire....... a lii iir 1 cii iir4 . An abandoned well shall be h sical decommissioned before it falls into a state of disrepair. A drilled well shall be decommissioned by a MassDEP Certified Well Driller before it falls into a state of disrepair. Please note that an abandoned well that falls into a state of disrepair may be considered a potential hazard to public health or safety and become reclassified as an unauthorized UIC Class V well that will require subsequent UIC registration for the purposes of properly closing the well. Will this proposed closure activity result in the complete closure of all wells associated with this registration application or with the existing UIC registration number? Only answer"yes"to this question if all of the stormwater discharges associated with the UIC well(s) included in this UIC registration application or with the existing UIC registration number that was previously assigned by MassDEP will discontinue upon completion of the proposed well closure activities. It is important that this question be answered correctly because MassDEP will determine whether or not the UIC registration for stormwater discharge will be completely closed out upon the completion of the proposed closure activities. The consequences of answering "yes"will be that any further stormwater discharges associated with this UIC registration number will be unauthorized. If you check off the "no" box for this question, enter the number of wells associated with this UIC registration number that will continue to receive stormwater discharges of this well type. Number of entry points to the system: There are three questions associated with the number of entry points. The number of entry points to a UIC stormwater well is the number of catch basins, and roof drain downspouts that are discharging to the well(s). Enter the number of entry points before closure, the number of entry points proposed for closure, and the number of entry points that will remain after the proposed closure activities have been completed. Only enter the number of entry points for the stormwater discharges associated with this UIC registration number. Proposed or previously completed well closure activities (check all that apply): Closure activities shall adhere to the Mass DEP Guidance Document#: BRP/DWM/DW/G04-3, Massachusetts Closure Requirements for Underground Injection Control(UICs) Wells (including shallow injection wells) iirnass.gov/e ea/docs/de, / ateiir lii Ithiru Iz/0c e ). The discussion of required laboratory analytical testing parameters in that document is focused on motor vehicle—waste disposal wells. For other types of"well category" and "well type" combinations the sampling parameters chosen will depend upon the types of contaminants that were either known to have been discharged to the well or that had the potential to have been discharged into the well. If properly maintained and operated, many UIC Class V stormwater discharge wells will not require sampling of fluids/sediments in the bottom of the well or in the area surrounding the well. If uncertain as to what sampling and laboratory analyses should be completed, you are encouraged to contact the MassDEP UIC Program at ASK U I C @ state iima us prior to submitting your Pre-Closure application. Check all boxes that describe the types of well closure activities associated with this UIC Pre-Closure application. You shall include both proposed closure activities and activities that will have already been completed at the time this application is submitted. The selection options include the following: • Clean out well(s); • Sample fluids/sediments in the bottom of the injection well; • Remove well(s) and any contaminated soil—the selection of this option indicates that the well(s)will be physically removed (excavated)from the ground; • Appropriate disposal of remaining fluids/sediments; • Conversion to other well type; Stormins.doc rev.08/13 Page 14 of 16 Massachusetts Department of Environmental Protection Bureau of Resource Protection — Drinking Water Program BRP WS 06 UIC Registration Stormwater Discharge Well Instructions and Supporting Materials • Note: Only select this option if the well is being converted to another UIC Class V well type. If you are converting to a non-UIC Class V well type (i.e. converting to an irrigation well, etc.)then you should not select this option and you should not select the following "well and all entry points physically decommissioned" option. If you select this option you will be asked to select the well category and type for the new purpose of the well. Note: a separate UIC registration application (BRP WS06) must be submitted for any conversion to a new well type). If you are converting to a non-UIC Class V well type (i.e. irrigation well)then you should indicate your intent in an attached narrative to your Pre-Closure application from; • Well(s) and entry points abandoned (physically decommissioned). The selection of this option indicates that the well, or one or more of the UIC wells, associated with this UIC Registration Number will be physically removed/filled-in/destroyed and that all entry points to the well will either be removed and/or the piping to the UIC well will be permanently sealed so that no fluid may continue to be directed toward the closed well.; • Partial Closure- Some of the current or past discharges will be discontinued. Other discharges of the well category and well type associated with this UIC Registration Number to the well(s)will continue; • Sample fluids/sediments from the area surrounding the injection well (as applicable); or, • Other(Describe). Proposed Laboratory Analytical Parameters for Soil Sampling Activities: The selection of soil or groundwater analytes shall be based upon the potential oil and/or hazardous materials that are known to have discharged to the UIC well or had the potential to be discharged to the UIC well. Laboratory analytical results from soil samples are often required for a stormwater discharge well that has one or more land uses with higher potential pollutant loads In many instances laboratory analyses are not required for the closure of the other types of UIC Class V stormwater discharge wells.
