Activities must be conducted to remove sediments, prevent the discharged water from eroding soil on the site, and preserve down gradient wetlands and ditches. Water should be pumped into a portable dewatering bag or a dewatering area. The dewatering area shall be located on a flat surface not within a runoff path. For non-vegetated dewatering areas, a layer of crushed stone with a minimum diameter of 2 inches should be installed. The dewatering area shall be encompassed with silt fence or sediment logs to allow infiltration of water into the ground. Dewatering shall be discharged within the limits of work as shown on the construction plans. All requirements of state law and permit requirements of local, state and federal agencies must be met, including the Construction Dewatering General permit for projects that propose to discharge construction dewatering water to wetlands. Installation Schedule: The dewatering facility should be installed prior to starting dewatering activities. A minimum of two dirt bags shall be on-site prior to commencing of earth moving activities. Inspections: Weekly: The dewatering facility area shall be inspected by an environmental monitor at least once every seven (7) days from the start of terrain alteration until the site is completed and stabilized; Additionally, the dewatering facility should be inspected daily by the Contractor during the active dewatering process. During/Post-Storm: The environmental monitor shall also inspect the dewatering facility during any rain event in which 0.25 inches of precipitation or more falls within a 24 hour period. If the environmental monitor is unable to be present during such a storm, an inspection shall be performed within 24 hours of the event. Maintenance: Special attention should be paid to the buffer area of the dewatering facility for any signs of erosion or flow concentration that may damage the buffer's vegetation and/or the underlying soil. Dewatering discharge should be stopped immediately upon any sign of instability or erosion in the receiving area. If a portable dewatering bag is used for the dewatering facility, check the bag daily for rips and repair or replace as needed. If a gravel pad is used, check the surface area for erosion and install additional crushed stone if necessary. The silt fence or sediment log perimeter adjacent to the downstream side of the dewatering facility should be checked for gaps,tears or other deficiencies and repaired/replaced as needed. Dewatering should be avoided during periods of intense, heavy rain. Any repairs or replacements to the dewatering facilities use should be done by the end of the same work day in which it is found or by the end of the following work day if removal by the same work day is not feasible. The dewatering effluent should be visually monitored to assess whether additional treatment is required to protect downstream receiving waters. Care must be exercised to prevent contact of 18 Stormwater Pollution Prevention Plan (SWPPP) Climate Controlled Self Storage Facility dewatering effluent with oil, grease, other petroleum products, toxic and/or hazardous materials. Contaminated runoff must be contained, treated, and discharged or removed in accordance with the Project Plans and Specifications, as well as NHDES requirements.

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 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 (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 are able to demonstrate that you meet one of the criteria listed in Appendix D with respect to the protection of species that are federally listed as endangered or threatened under the Endangered Species Act (ESA) and federally designated critical habitat; 1.1.6 You have completed the screening process in Appendix E relating to the protection of historic properties; and 1 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 2012 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 2017 Construction General Permit (CGP) (as modified) 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 cause, have the reasonable potential to cause, or contribute to an excursion above any applicable water quality standard. 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 will not cause, have the reasonable potential to cause, or contribute to an excursion above any applicable water quality standard. 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 Notice of Intent (NOI) unless and until you notify your applicable EPA Regional Office (see Appendix L) 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 not lead to discharges that cause an exceedance of water quality standards. 1.2 TYPES OF DISCHARGES AUTHORIZED5 1.2.1 The following stormwater discharges are authorized under this permit provided that appropriate stormwater controls are designed, installed, and maintained (see Parts 2 and 3): a.. Stormwater discharges, including stormwater runoff, snowmelt runoff, and surface runoff and drainage, associated with construction activity under 40 CFR 122.26(b)(14) or 122.26(b)(15)(i); b. Stormwater discharges designated by EPA as needing a permit under 40 CFR 122.26(a)(1)(v) or 122.26(b)(15)(ii); 4 Note:Your site will be considered to discharge to a Tier 2,Tier 2.5, or Tier 3 water if the first 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 water of the U.S. to which you discharge is the waterbody that receives the stormwater discharge from the storm sewer system.See list of Tier 2,Tier 2.5, and Tier 3 waters in Appendix F. 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 2 2017 Construction General Permit (CGP) (as modified) c. Stormwater discharges from construction support activities (e.g., concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas) provided that: i. The support activity is directly related to the construction site required to have permit coverage for stormwater discharges; ii. The support activity is not a commercial operation, nor does it serve multiple unrelated construction sites; iii. The support activity does not continue to operate beyond the completion of the construction activity at the site it supports; and iv. Stormwater controls are implemented in accordance with Part 2 and Part 3 for discharges from the support activity areas. d. Stormwater discharges from earth-disturbing activities associated with the construction of staging areas and the construction of access roads conducted prior to active mining. 1.2.2 The following non-stormwater discharges associated with your construction activity are authorized under this permit provided that, with the exception of water used to control dust and to irrigate vegetation in stabilized areas, these discharges are not routed to areas of exposed soil on your site and you comply with any applicable requirements for these discharges in Parts 2 and 3: a. Discharges from emergency fire-fighting activities; b. Fire hydrant flushings; c. Landscape irrigation; d. 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; 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 water of the U.S., storm drain inlet, or stormwater conveyance, unless the conveyance is connected to a sediment basin, sediment trap, or similarly effective control; i. 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. Construction dewatering water 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 Page 3 2017 Construction General Permit (CGP) (as modified) discharge authorized by a different NPDES permit and/or a discharge that does not require N PDES permit authorization. 1.3 PROHIBITED DISCHARGES6 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 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. To prevent the above-listed prohibited non-stormwater discharges, operators must comply with the applicable pollution prevention requirements in Part 2.3. 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 requirements, 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 commencing construction activities. 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. 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 2017 CGP, unless you received a waiver from your EPA Regional Office.

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 J. 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. Table 1 NOI Submittal Deadlines and Official Start Date for Permit Coverage. Type of Operator NOI Submittal Deadline' Permit Authorization Date$ 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 16, activities. received a complete NOI, 2017) unless EPA notifies you that your authorization is delayed Operator of an existing site (i.e., a site No later than May 17,2017. or denied. with 2012 CGP coverage where construction activities commenced prior to February 16, 2017 New operator of a permitted site (i.e., At least 14 calendar days before an operator that through transfer of the date the transfer to the new ownership and/or operation replaces operator will take place. the operator of an already permitted construction site that is either a "new site"or an "existing site" 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. 1.4.4 Modifying your NOI 7 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. 8 Discharges are not authorized if your NOI is incomplete or inaccurate or if you are not eligible for permit coverage. Page 5 2017 Construction General Permit (CGP) (as modified) 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 1.4.1. 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 J. 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. 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, 2022; or C. You fail to submit an NOI for coverage under a revised 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 that it is visible from the public road that is nearest to the active part of the construction site, and it must use a font large enough to be readily viewed from a public right-of-way.9 At a minimum, the notice must include: a. The NPDES ID (i.e., permit tracking number assigned to your NOI); 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 sRwww. 0 . v/)Q con t ct-u -s,t rm t r= re i n ];" and d. The following statement "If you observe indicators of stormwater pollutants in the discharge or in the receiving waterbody, contact the EPA through the following website: -t-t s: . of irc m n it irt,..... n lilt nm in-tal viola-tioins.,, 2 TECHNOLOGY-BASED EFFLUENT LIMITATIONS You must comply with the following technology-based effluent limitations in this Part for all authorized discharges.10 9 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. 10 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 its (their) Page 6 2017 Construction General Permit (CGP) (as modified) 2.1 GENERAL STORMWATER CONTROL DESIGN, INSTALLATION.. AND MAINTENANCE REQUIREMENTS You must design, install, and maintain stormwater controls required in Parts 2.2 and 2.3 to minimize the discharge of pollutants in stormwater from construction activities. To 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; b. The nature of stormwater runoff 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. 2.1.2 Design and install all stormwater controls in accordance with good engineering practices, including applicable design specifications.I' 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.12 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 that 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.13 b. If at any time you find that a stormwater control needs routine maintenance,you must immediately initiate the needed maintenance work, and complete such work by the close of the next business day. installation/implementation.See Part 7.2.6. 11 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 and 2.3. 12 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. 13 Any departures from such maintenance recommendations made by the manufacturer must reflect good engineering practices and must be explained in your SWPPP. Page 7 2017 Construction General Permit (CGP) (as modified) c. If at any time you find that a stormwater control needs repair or replacement,you must comply with the corrective action requirements in Part 5. 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 when a water of the U.S. is located within 50 feet of the site's earth disturbances. a.. Compliance Alternatives. For any discharges to waters of the U.S. 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 iii. 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 G, Part G.2 for additional conditions applicable to each compliance alternative. b. Exceptions. See Appendix G, Part G.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 infeasible. 2.2.3 Install sediment controls along any perimeter areas of the site that will receive pollutant discharges.14 a.. Remove sediment before it has accumulated to one-half of the above-ground height of any perimeter control. b. 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 techniques15 at all points that exit onto paved roads. 14 Examples of perimeter controls include filter berms,silt fences,vegetative strips,and temporary diversion dikes. 15 Examples of appropriate stabilization techniques include the use of aggregate stone with an underlying geotextile or non-woven filter fabric, and turf mats. Page 8 2017 Construction General Permit (CGP) (as modified) 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 controls16 are implemented to minimize sediment track-out; c. Implement additional track-out controls» 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 sediment into any stormwater conveyance, storm drain inlet, or water of the U.S.18 2.2.5 Manage stockpiles or land clearing debris piles composed, in whole or in part, of sediment and/or soil: a.. Locate the piles outside of any natural buffers established under Part 2.2.1 and away from any stormwater conveyances, drain inlets, and areas where stormwater flow is concentrated; b. Install a sediment barrier along all downgradient perimeter areas;19 c. For piles that will be unused for 14 or more days, provide cover20 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 stormwater conveyance, storm drain inlet, or water of the U.S. 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). 16 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). 17 Examples of additional track-out controls include the use of wheel washing, rumble strips, and rattle plates. 18 Fine grains that remain visible (i.e., 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. 19 Examples of sediment barriers include berms, dikes,fiber rolls, silt fences,sandbags,gravel bags, or straw bale. 20 Examples of cover include tarps, blown straw and hydroseeding. Page 9 2017 Construction General Permit (CGP) (as modified) 2.2.8 Preserve native topsoil, unless infeasible.21 2.2.9 Minimize soil compaction.22 In areas of your site where final vegetative stabilization will occur or where infiltration practices will be installed: 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 flow from your site to a water of the U.S., provided you have authority to access the storm drain inlet;23 and b. Clean, or remove and replace, the 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. 24. 2.2.12 If you install a sediment basin or similar impoundment: a.. Situate the basin or impoundment outside of any water of the U.S. 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 (see Appendix H); or ii. 3,600 cubic feet per acre drained. 21 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. 22 Minimizing soil compaction is not required where the intended function of a specific area of the site dictates that it be compacted. 23 Inlet protection measures can be removed in the event of flood conditions or to prevent erosion. 24 Examples of control measures 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 stormwater conveyance and at the outfall to slow down runoff. Page 10 2017 Construction General Permit (CGP) (as modified) d. Utilize outlet structures that withdraw water from the surface of the sediment basin or similar impoundment, unless infeasible;25 e. Use erosion controls and velocity dissipation devices to prevent erosion at inlets and outlets; and 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, decks, 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 that all persons who handle and use treatment chemicals at the construction site are provided with appropriate, product-specific training. 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 that the use of such chemicals will not cause an exceedance of water quality standards. 25 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 1 1 2017 Construction General Permit (CGP) (as modified) 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, sodding, mulching, erosion control blankets, hydromulch, gravel) that minimize erosion from exposed portions of the site in accordance with Parts 2.2.14a and 2.2.14b. a.. Stabilization Deadlines:26 Total Amount of Land Disturbance Deadline Occurring At Any One Time27 i. Five acres or less(55.0) Initiate the installation of stabilization measures immediately28 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;29 course of a project, but that limit and disturbance at any one time (i.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 (:55.0) after stabilization has been initiated.30 26 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. 27 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. 28 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. 29 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. 30 If vegetative stabilization measures are being implemented,stabilization is considered "installed" when all activities necessary to seed or plant the area are completed. If non-vegetative stabilization measures are being implemented,stabilization is considered "installed" when all such measures are implemented or applied. Page 12 2017 Construction General Permit (CGP) (as modified) ii. More than five acres(>5.0) Initiate the installation of stabilization measures immediately3l in any areas of exposed soil where construction activities have permanently ceased or will be temporarily inactive for 14 or more calendar days;32 and • Complete the installation of stabilization measures as soon as practicable, but no later than seven (7) calendar days after stabilization has been initiated.33 iii. Exceptions: (a) Arid, semi-arid, and drought-stricken areas (as defined in Appendix A). If it is the seasonally dry period or a period in which drought is occurring, and vegetative stabilization measures are being used: (i) Immediately initiate and, within 14 calendar days of a 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; (ii) 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 (iii) 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. (b) Operators that are affected by unforeseen circumstances34 that delay the initiation and/or completion of vegetative stabilization: (i) Immediately initiate and, within 14 calendar days, complete the installation of temporary non-vegetative stabilization measures to prevent erosion; (ii) 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 (iii) 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. (c) 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 31 See footnote 27 32 See footnote 28 33 See footnote 29 34 Examples include problems with the supply of seed stock or with the availability of specialized equipment and unsuitability of soil conditions due to excessive precipitation and/or flooding. Page 13 2017 Construction General Permit (CGP) (as modified) practicable, but no later than seven (7) calendar days after stabilization has been initiated. b. Final Stabilization Criteria (for any areas not covered by permanent structures): i. Establish uniform, perennial vegetation (i.e., evenly distributed, without large bare areas) that provides 70 percent or more of the cover that is provided by vegetation native to local undisturbed areas; and/or ii. Implement permanent non-vegetative stabilization measures35 to provide effective cover. iii. 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 cover that is provided by vegetation 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 that 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 2.2.14b final stabilization criteria does 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 REQUIREMENTS36 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. 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;37 35 Examples of permanent non-vegetative stabilization measures include riprap, gravel,gabions, and geotextiles. 36 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). 37 Examples of effective means include: • Locating activities away from waters of the U.S. and stormwater inlets or conveyances so that stormwater coming into contact with these activities cannot reach waters of the U.S.; • Providing secondary containment (e.g., spill berms, decks, 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.

For building materials and building products39, provide either (1) cover (e.g., plastic sheeting, temporary roofs) to minimize the exposure of these products to precipitation and to stormwater, or (2) a similarly effective means designed to minimize the discharge of pollutants from these areas. 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: i. 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: 38 Examples of effective means include locating activities away from waters of the U.S.and stormwater inlets or conveyances 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. 39 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 15 2017 Construction General Permit (CGP) (as modified) i. Store chemicals in water-tight containers, and provide either (1) cover(e.g., plastic sheeting, temporary roofs) to minimize the exposure of these containers to precipitation and to stormwater, or (2) a similarly effective means designed to minimize the discharge of pollutants from these areas (e.g., having a spill kit available on site and ensuring personnel are available to respond expeditiously in the event of a leak or spill), or provide secondary containment (e.g., spill berms, decks, spill containment pallets); and ii. 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:40 i. Separate hazardous or toxic waste from construction and domestic waste; ii. Store waste in sealed containers,which are constructed of suitable materials to prevent leakage and corrosion, and which are 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, decks, 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 vi.

Provide waste containers (e.g., dumpster, trash receptacle) of sufficient size and number to contain construction and domestic wastes; ii. Keep waste container lids closed when not in use and close lids at the end of the business day for those containers that are actively used throughout the day. For waste containers that do not have lids, provide either (1) cover (e.g., a tarp, plastic sheeting, temporary roof) to minimize exposure of wastes to precipitation, 40 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. 41 Examples of construction and domestic waste include packaging materials,scrap construction materials, masonry products, timber, pipe and electrical cuttings, plastics,styrofoam, concrete, demolition debris; and other trash or building materials. Page 16 2017 Construction General Permit (CGP) (as modified) or (2) a similarly effective means designed to minimize the discharge of pollutants (e.g., secondary containment); iii. On business days, clean up and dispose of waste in designated waste containers; and iv. Clean up immediately if containers overflow. f. For sanitary waste, position portable toilets so that they are secure and will not be tipped or knocked over, and located away from waters of the U.S. and stormwater inlets or conveyances. 2.3.4 For washing applicators and containers used for stucco, paint, concrete,form release oils, curing compounds, or other materials: a.. Direct wash water into a leak-proof container or leak-proof and lined pit designed so that no overflows can occur due to inadequate sizing or precipitation; b. Handle washout or cleanout wastes as follows: i. Do not dump liquid wastes in storm sewers or waters of the U.S.; ii. Dispose of liquid wastes in accordance with applicable requirements in Part 2.3.3; and iii. Remove and dispose of hardened concrete waste consistent with your handling of other construction wastes in Part 2.3.3; and c. Locate any washout or cleanout activities as far away as possible from waters of the U.S. and stormwater inlets or conveyances, and, to the extent feasible, designate areas to be used for these activities and conduct such activities only in these areas. 2.3.5 For the application of fertilizers: 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 7.2.6.b.ix; 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; c. Avoid applying before heavy rains that could cause excess nutrients to be discharged; d. Never apply to frozen ground; e. Never apply to stormwater conveyance channels; 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 1 10, 40 CFR 117, or 40 CFR 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 1 10, 40 CFR 117, and 40 CFR 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 Page 17 2017 Construction General Permit (CGP) (as modified) 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 in ground water or accumulated stormwater that is removed from excavations, trenches, foundations, vaults, or other similar points of accumulation, in accordance with Part 1.2.2.42 2.4.1 Treat dewatering discharges with controls to minimize discharges of pollutants;43 2.4.2 Do not discharge visible floating solids or foam; 2.4.3 Use an oil-water separator or suitable filtration device (such as a cartridge filter) that is designed to remove oil, grease, or other products if dewatering water is found to contain these materials; 2.4.4 To the extent feasible, use vegetated, upland areas of the site to infiltrate dewatering water before discharge. You are prohibited from using waters of the U.S. as part of the treatment area; 2.4.5 At all points where dewatering water is discharged, comply with the velocity dissipation requirements of Part 2.2.1 1; 2.4.6 With backwash water, either haul it away for disposal or return it to the beginning of the treatment process; and 2.4.7 Replace and clean the filter media used in dewatering devices when the pressure differential equals or exceeds the manufacturer's specifications. 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. 42 Uncontaminated, clear (non-turbid) dewatering water can be discharged without being routed to a control. 43 Appropriate controls include sediment basins or sediment traps,sediment socks, dewatering tanks, tube settlers,weir tanks, filtration systems (e.g., bag or sand filters), and passive treatment systems that are designed to remove sediment.Appropriate controls to use downstream of dewatering controls to minimize erosion include vegetated buffers, check dams, riprap, and grouted riprap at outlets. Page 18 2017 Construction General Permit (CGP) (as modified) 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 DISCHARGE LIMITATIONS FOR SITES DISCHARGING TO SENSITIVE WATERS44 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, you must comply with the inspection frequency specified in 4.3 and you must comply with the stabilization deadline specified in Part 2.2.14.a.iii.(c).45 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, including for it to be consistent with the assumptions of any available wasteload allocation in any applicable TMDL, or if coverage under an individual permit is necessary. 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, or other measures are necessary to comply with the applicable 44 Sensitive waters include waters that are impaired and Tier 2,Tier 2.5,and Tier 3 waters. "Impaired waters" are those waters identified by the state, tribe,or EPA as not meeting an applicable water quality standard and (1) requires development of a TMDL (pursuant to section 303(d) of the CWA;or (2) is addressed by an EPA-approved or established TMDL; or (3) is not in either of the above categories but the waterbody is covered by a pollution control program that meets the requirements of 40 CFR 130.7(b)(1).Your construction site will be considered to discharge to an impaired water if the first water of the U.S. to which you discharge is an impaired water for the pollutants contained in the discharge from your site. For discharges that enter a storm sewer system prior to discharge, the first water of the U.S.to which you discharge is the waterbody that receives the stormwater discharge from the storm sewer system. For assistance in determining whether your site discharges to impaired waters, EPA has developed a tool that is available both within the electronic NOI form in NeT, and at ..::...p ...®./ ................q..:: .lr.. as ov oll as,.l.------e n des s,.l.0irr cr1,eir dii chair e.cfrm. Tiers 2,2.5 and 3 refer to waters either identified by the state as high quality waters or Outstanding National Resource Waters under 40 CFR 131.12(a)(2) and (3). For the purposes of this permit,you are considered to discharge to a Tier 2,Tier 2.5,or Tier 3 water if the first water of the U.S. to which you discharge is identified by a state, tribe, or EPA as Tier 2,Tier 2.5, or Tier 3. For discharges that enter a storm sewer system prior to discharge,the water of the U.S. to which you discharge is the first water of the U.S. that receives the stormwater discharge from the storm sewer system.See list of Tier 2,Tier 2.5, and Tier 3 waters in Appendix F. EPA may determine on a case-by-case basis that a site discharges to a sensitive water. 45 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. Page 19 2017 Construction General Permit (CGP) (as modified) 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 controls46 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. 4 SITE INSPECTION REQUIREMENTS 4.1 PERSON(S) RESPONSIBLE FOR INSPECTING SITE The person(s) inspecting your site may be a person on your staff or a third party you hire to conduct such inspections. You are responsible for ensuring that the person who conducts inspections is a "qualified person.1147 4.2 FREQUENCY OF INSPECTIONS.48 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 sensitive 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 hours of the occurrence of a storm event of 0.25 inches or greater, or the occurrence of runoff from snowmelt sufficient to cause a discharge.49 To determine if a storm event of 0.25 inches or greater has occurred on your site, 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 day of rainfall during normal business hours that measures 0.25 inches or greater, you must record the total rainfall measured for that day in accordance with Part 4.7.1 d. 46 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, using tools that minimize dust and heat (<2120F). For additional information,refer to Part 2.3.3 of the CGP Fact Sheet. 47 A "qualified person" is 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. 48 Inspections are only required during the site's normal working hours. 49 "Within 24 hours of the occurrence of a storm event" means that you must conduct an inspection within 24 hours once a storm event has produced 0.25 inches within a 24-hour period, even if the storm event is still continuing.Thus,if you have elected to inspect bi-weekly in accordance with Part 4.2.2 and there is a storm event at your site that continues for multiple days, and each day of the storm produces 0.25 inches or more of rain,you must conduct an inspection within 24 hours of the first day of the storm and within 24 hours after the end of the storm. Page 20 2017 Construction General Permit (CGP) (as modified) 4.3 INCREASE IN INSPECTION FREQUENCY FOR SITES DISCHARGING TO SENSITIVE 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 (see Part 3.2), instead of the inspection frequency specified in Part 4.2, you must conduct inspections in accordance with the following inspection frequencies: Once every seven (7) calendar days and within 24 hours of the occurrence of a storm event of 0.25 inches or greater, or the occurrence of runoff from snowmelt sufficient to cause a discharge.To determine if a storm event of 0.25 inches or greater has occurred on your site, 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 day of rainfall during normal business hours that measures 0.25 inches or greater, you must record the total rainfall measured for that day in accordance with Part 4.7.1 d. 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 in any area of your site where the stabilization steps in 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 2.2.14a have been completed. After the first month, inspect once more within 24 hours of the occurrence of a storm event of 0.25 inches or greater. 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 of 0.25 inches or greater. 4.4.2 Arid, semi-arid, or drought-stricken areas (as defined in Appendix A). If it is the seasonally dry period 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 of 0.25 inches or greater. You must document that you are using this reduced schedule and the beginning and ending dates of the seasonally dry period in your SWPPP.To determine if a storm event of 0.25 inches or greater has occurred on your site, 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 day of rainfall during normal business hours that measures 0.25 inches or greater, you must record the total rainfall measured for that day in accordance with Part 4.7.1 d. 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: Page 21 2017 Construction General Permit (CGP) (as modified) i. Runoff is 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; 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. Runoff is 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;50 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 drainageways designed to divert, convey, and/or treat stormwater; 4.5.5 All points of discharge from the site; and 4.5.6 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 During your site inspection, you must at a minimum: 4.6.1 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; 50 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 22 2017 Construction General Permit (CGP) (as modified) 4.6.2 Check for the presence of conditions that could lead to spills, leaks, or other accumulations of pollutants on the site; 4.6.3 Identify any locations where new or modified stormwater controls are necessary to meet the requirements of Parts 2 and/or 3; 4.6.4 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, the banks of any waters of the U.S. flowing within or immediately adjacent to the site; 4.6.5 Identify any incidents of noncompliance observed; 4.6.6 If a discharge is occurring during your inspection: 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. 6.2 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, 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. 51 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. Page 25 2017 Construction General Permit (CGP) (as modified) 6.3 At a minimum, members of the stormwater team must be trained to understand the following if related to the scope of their job duties (e.g., only personnel responsible for conducting inspections need to understand how to conduct inspections): a. The permit deadlines associated with installation, maintenance, and removal of stormwater controls and with 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. 6.4 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 N01.52,53 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. 7.2.2 Stormwater Team. Identify the personnel (by name or position) that are part of the stormwater team, as well as their individual responsibilities, including which members are responsible for conducting inspections. 52 The SWPPP does not establish the effluent limits and other permit terms and conditions that apply to your site's discharges; these limits,terms, and conditions are established in this permit. 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 for both operators to be in compliance with the permit. However, Operator A remains responsible for permit compliance if Operator B fails to implement any measures 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 compromise any other operators' controls and/or any shared controls.

Idaho's An tide aradation Policx.The WQS contain an antidegradation policy providing three levels of protection to water bodies in Idaho (IDAPA 58.01.02.051). 1. Tier I Protection. The first level of protection applies to all water bodies subject to Clean Water Act jurisdiction and ensures that existing uses of a water body and the level of water quality necessary to protect those existing uses will be maintained and protected (IDAPA 58.01.02.051.01; 58.01.02.052.01). Additionally, a Tier 1 review is performed for all new or reissued permits or licenses (IDAPA 58.01.02.052.05). 2. Tier II Protection.The second level of protection applies to those water bodies considered high quality and ensures that no lowering of water quality will be allowed unless deemed necessary to accommodate important economic or social development (IDAPA 58.01.02.051.02; 58.01.02.052.08). 3. Tier III Protection.The third level of protection applies to water bodies that have been designated outstanding resource waters and requires that activities not cause a lowering of water quality (IDAPA 58.01.02.051.03; 58.01.02.052.09). DEQ is employing a water body by water body approach to implementing Idaho's antidegradation policy.This approach means that any water body fully supporting its beneficial uses will be considered high quality (IDAPA 58.01.02.052.05.a). Any water body not fully supporting its beneficial uses will be provided Tier I protection for that use, unless specific circumstances warranting Tier II protection are met (IDAPA 58.01.02.052.05.c).The most recent federally approved Integrated Report and supporting data are used to determine support status and the tier of protection (IDAPA 58.01.02.052.05). b. Pollutants of Concern. The primary pollutants of concern associated with stormwater discharges from construction activities are sediment, typically measured as total suspended solids and turbidity. Other potential pollutants include the following: phosphorus, nitrogen, pesticides, organics, metals, PCBs, petroleum products, construction chemicals, and solid wastes. c. Receiving Water Body Level of Protection. The CGP provides coverage to construction activities throughout the entire State of Idaho. Because of the statewide applicability, all of the jurisdictional waters within Idaho could potentially receive discharges either directly or indirectly from activities covered under the CGP. DEQ applies a water body by water body approach to determine the level of antidegradation awater body will receive. All waters in Idaho that receive discharges from activities authorized under the CGP will receive, at minimum Tier I antidegradation protection because Idaho's antidegradation policy applies to all waters of the state. Water bodies that fully support their aquatic life or recreational uses are considered to be high quality waters and will receive Tier II antidegradation protection. Although Idaho does not currently have any Tier III designated outstanding resource waters (ORWs) designated, it is possible for a water body to be designated as an ORW during the life of the CGP. Because of this potential, the antidegradation review also assesses whether the permit complies with the Page 59 2017 Construction General Permit (CGP) (as modified) outstanding resource water requirements of Idaho's antidegradation policy. To determine the support status of the receiving water body, persons filing a Notice of Intent (NOI) for coverage under this general permit must use the most recent EPA-approved Integrated Report, available on Idaho DEQ's website: n i-t ri n .assess..................... .irk...............in't. ai,i ..::�................ r l ,...r ir.l.. . High quality waters are identified in Categories 1 and 2 of the Integrated Report. If a water body is in either Category 1 or 2, it is a Tier II water body. Unassessed waters are identified as Category 3 of DEQ's Integrated Report. These waters require a case-by-case determination to be made by DEQ based on available information at the time of the application for permit coverage. If a water body is unassessed, the applicant is directed to contact DEQ for assistance in filing the NOI. Impaired waters are identified in Categories 4 and 5 of the Integrated Report. Category 4(a) contains impaired waters for which a TMDL has been approved by EPA. Category 4(b) contains impaired waters for which controls other than a TMDL have been approved by EPA. Category 5 contains waters which have been identified as "impaired," for which a TMDL is needed.These waters are Tier I waters, for the use which is impaired. With the exception, if the aquatic life uses are impaired for any of these three pollutants dissolved oxygen, pH, or temperature and the biological or aquatic habitat parameters show a health, balanced biological community, then the water body shall receive Tier II protection, in addition to Tier I protection, for aquatic life uses (IDAPA 58.01.02.052.05.c.i.).

Turbidity Monitorin_g. The permittee must conduct turbidity monitoring during construction activities and thereafter on days where there is a direct discharge of pollutants from an unstabilized portion of the site which is causing a visible plume to a water of the U.S. A properly and regularly calibrated turbidimeter is required for measurements analyzed in the field (preferred method), but grab samples may be collected and taken to a laboratory for analysis. If the permittee can demonstrate that there will be no direct discharge from the construction site, then turbidity monitoring is not required. When monitoring is required, a sample must be taken at an undisturbed area immediately upstream of the project area to establish background turbidity levels for the monitoring event. Background turbidity, location, date and time must be recorded prior to monitoring downstream of the project area. A sample must also be taken immediately downstream from any point of discharge and within any visible plume. The turbidity, location, date and time must be recorded.The downstream sample must be taken immediately following the upstream sample in order to obtain meaningful and representative results. Results from the compliance point sampling or observation78 must be compared to the background levels to determine whether project activities are causing an exceedance of state WQS. If the downstream turbidity is 50 NTUs or more than the upstream turbidity, then the project is causing an exceedance of WQS.Any exceedance of the turbidity standard must be reporting to the appropriate DEQ regional office within 24 hours. The following six (6) steps should be followed to ensure compliance with the turbidity standard: 1. If a visible plume is observed, quantify the plume by collecting turbidity measurements from within the plume and compare the results to Idaho's instantaneous numeric turbidity criterion (50 NTU over the background). 78 A visual observation is only acceptable to determine whether BMPs are functioning properly. If a plume is observed,the project may be causing an exceedance of WQS and the permittee must collect turbidity data and inspect the condition of the projects BMPs. If the BMPs appear to be functioning to their fullest capability and the turbidity is 50 NTUs or more than the upstream turbidity,then the permittee must modify the activity or implement additional BMPs (this may also include modifying existing BMPs). Page 61 2017 Construction General Permit (CGP) (as modified) 2. If turbidity is less than 50 NTU instantaneously over the background turbidity; continue monitoring as long as the plume is visible. If turbidity exceeds background turbidity by more than 50 NTU instantaneously then stop all earth disturbing construction activities and proceed to step 3. 3. Take immediate action to address the cause of the exceedance.That may include inspection the condition of project BMPs. If the BMPs are functioning to their fullest capability, then the permittee must modify project activities and/or BMPs to correct the exceedance. 4. Notify the appropriate DEQ regional office within 24 hours. 5. Possibly increase monitoring frequency until state water quality standards are met. 6. Continue earth disturbing construction activities once turbidity readings return to within 50 NTU instantaneously and 25 NTU for more than ten consecutive days over the background turbidity. Copies of daily logs for turbidity monitoring must be available to DEQ upon request.The report must describe all exceedances and subsequent actions taken, including the effectiveness of the action. e. Reporting of Discharges Containing Hazardous Materials or Petroleum Products. All spills of hazardous material, deleterious material or petroleum products which may impact waters (ground and surface) of the state shall be immediately reported. Call 911 if immediate assistance is required to control, contain or clean up the spill. If no assistance is needed in cleaning up the spill, contact the appropriate DEQ regional office in the table below during normal working hours or Idaho State Communications Center after normal working hours. If the spilled volume is above federal reportable quantities, contact the National Repose Center.

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.
