PLANNING This Stormwater Pollution Prevention Plan and Erosion and Sediment Control Plan (SWPPP) is intended to identify measures for control of stormwater runoff and for minimizing impacts resulting from construction activities associated with the site redevelopment proposed for the Recreation Complex project located in North Andover, Massachusetts. See USGS Locus Maps included in Appendix A for Site location Maps. The SWPPP has been prepared in accordance with the regulations, guidelines, and conditions set forth by the US Environmental Protection Agency (EPA) in its Final Notice of the National Pollutant Discharge Elimination System (NPDES) General Permit for Stormwater Discharges from Construction Sites and the Town of North Andover Stormwater Management and Erosion Control Regulations. 1.1 PROJECT/SITE INFORMATION The Town of North Andover(the Proponent) proposes to redevelop the property located at 0 Grogan Field (Grogan's Field) in North Andover, MA by reconstructing the fields at the site and constructing appurtenant parking areas, drainage systems and utility services. 1.1.1 Subject Parcel Information Project/Site Name: Grogan Field Restoration Name and Address of Owner of Record: Town of North Andover 120 Main Street North Andover, MA 01845 Street Address of Project: 67 Baldwin Street North Andover, MA 01845 Assessors Map & Lot: Map 13 Lot 33 County or Similar Subdivision: Essex County 3 Latitude and Longitude: Latitude: N 420 42' 09" Longitude: W 710 08' 14" Title Reference: None The project is not located in Indian Country and is not considered a Federal Facility.

The Operator must complete and file a NOT with the EPA. A blank NOT form is provided in Appendix C. 1.3 NATURE AND SEQUENCE OF CONSTRUCTION ACTIVITY The proposed project is recreational in nature and is anticipated to be constructed in one general phase. The goal of one phase of construction is to minimize the duration of construction impacts on surrounding areas. One phase construction also helps to ensure the timely opening of the entire site. It is currently projected that the full build-out of the Project will begin in Fall 2019 and will be complete in Spring 2020. Due to the nature of the site and the quick construction schedule most of the site will be disturbed and stabilized during the first phase of construction. This SWPPP provides a description of the demolition and construction activities. The construction of the Project is expected to take approximately four months with the following sequence of major site work elements: ➢ Installation of erosion controls and tree protection; ➢ Installation of stabilized construction entrances and exits ➢ Removal and replacement of unsuitable subsurface materials, pavement removal and clearing and grubbing, other earth moving operations ➢ Stabilize surfaces within 14 days after land disturbance in any portion of the site has ceased or is halted temporarily. ➢ Installation of subsurface materials 5 ➢ Excavation for building foundations ➢ Installation of Building Foundations ➢ Demolition and removal of existing utility lines ➢ Installation of new site utility lines; ➢ Installation of new infiltration areas ➢ Installation of underdrain systems. ➢ Installation of natural turf field. ➢ Installation of bituminous and concrete paving; ➢ Final completion of all landscaping, infrastructure and required mitigation (Summer 2020) 1.3.1 Construction Hours Construction of the Project will conform to all local, state, and federal laws and employ all reasonable means to minimize inconvenience to residents and businesses in the general area. Exterior construction of the Project will occur no earlier than 7:00 AM and no later than 6:00 PM on any weekday, except for certain operations such as concrete finishing and emergency repairs. On Saturdays, exterior construction will occur no earlier than 7:00 AM and no later than 5:00 PM, with the same exceptions. The Building Inspector may allow longer hours of construction under special circumstances, provided that a written request is provided to the Building Inspector in advance (except in emergency situations). There shall be no exterior construction on Sunday or any state or federal legal holiday. Hours of operation will be enforced by the North Andover Police Department. If blasting or rock crushing is to occur, these activities will be carried out in accordance with all federal, state, and local blasting permit practices. 1.4 SOILS, SLOPES AND CURRENT DRAINAGE PATTERNS 1.4.1 Topography, Geology and Soils The project site consists of an existing athletic field including a full size baseball field. The site is primarily lawn recreational fields with the exception of the skinned infields and the paved parking area. The overall site gradient slopes from south side of the field to north of the fields and parking area. The site drains to catch basin in the lawn area in the north off site and onto the abutter's property in the in the northeast of the site. The parking areas drain to the catch basins in the street. The Natural Resources Conservation Service (MRCS) formerly known as the Soil Conservation Services (SCS), Soil Survey for the Town of North Andover, Essex County, Massachusetts identifies various soil types at the site, all of which are comprised of fine sandy loam Hydrologic Soils Group B. 1.4.2 Surface and Groundwater Hydrology The Project work area is located outside the 100 year floodplain within Flood Hazard Zone C (area of minimal flooding) as shown on the Flood Insurance Rate Map (FIRM)for the Town of 6 North Andover, Massachusetts, Essex County, Map No. 25009C209F, dated July 3, 2012. 1.4.3 Drainage Patterns The overall site gradient slopes from south of the field to the north and north east corner of the fields and parking area. The site drains to catch basin in the lawn area in the north off site and onto the abutter's property in the in the northeast of the site. The parking areas drain to the catch basins in the street. The proposed site will predominately follow the slope of the existing site and drain from the south of the fields to the north of the fields. The new paved areas will be directed through a natural grass swale to an area drain which will direct stormwater to an underground infiltration area. Runoff from the natural turf field will collect follow existing drainage patterns to the catch basin in the north of the property and onto abutting properties. Overflow from the infiltration chambers will connect to the existing drainage systems outletting to Baldwin Street in the The stormwater management system includes provisions to match the peak rate of runoff and total volume. 1.5 CONSTRUCTION STATISTICS The construction site contains a total of 4.33 acres. The construction of the project as proposed will result in an increase of 0..23 acres of impervious area. The existing construction site has approximately 0.27 acres of impervious area. The proposed construction site has approximately 0.50 acres of impervious area. Impervious area calculations are based on surface materials having a Curve Number (CN)of greater than 85 as defined in the North Andover Stormwater Management and Erosion Control Regulations. 1.6 RECEIVING WATERS The project is within the watershed that drains towards the Shawsheen River. No new discharges are proposed to the Shawsheen River watershed. 1.6.1 Direct Impacts to Resource Areas There are no direct impacts to wetland resources resulting from the Project. 1.7 SITE FEATURES AND SENSITIVE AREAS TO BE PROTECTED There are no site features and sensitive areas to be protected during construction. 7 1.8 POTENTIAL SOURCES OF POLLUTION The potential sources of pollution from the project are sediments resulting from earth excavation and grading activities and fueling of construction vehicles. These will be controlled by the erosion and sediment control plan discussed later in this SWPPP. There are no other sources of pollution from the construction site which may reasonably be expected to affect the quality of the stormwater discharges from the construction site. 1.9 ENDANGERED SPECIES The Massachusetts Natural Heritage Atlas, online as of November 2018, does not show any priority and estimated habitat of rare species. 1.10 HISTORIC PRESERVATION Review of the Inventory of Historic and Archaeological Assets of the Commonwealth indicates that there are no recorded aboveground resources located in or adjacent to the project site area. 1.11 COMPLIANCE WITH FEDERAL, STATE AND LOCAL REGULATIONS A copy of the NPDES General Permit Conditions is attached hereto as Appendix D. To our knowledge there are no other Federal, State or local Programs that are applicable to stormwater management, erosion control, and pollution minimization at this job site. The Contractor will comply with all conditions of the NPDES Construction General Permit, including the conditions related to maintaining the SWPPP and evidence of compliance with the SWPPP at the job site and allowing regulatory personnel access to the job site and to records in order to determine compliance. 8 2.0 CONSTRUCTION SEQUENCING AND EROSION AND SEDIMENT CONTROL.

Erosion Control and Construction Sequencing With regard to work proposed on the project and erosion and siltation control, the sequence of activities will generally take place as follows: 1. Prior to general pavement removal, clearing, grubbing or topsoil stripping, place all tree protection, strawbales, silt fence, and erosion control dikes in the location shown on the drawings. Although installation of these measures can be phased according to the 10 construction schedule, strawbales, silt fence, and erosion control dikes must be in place prior to any work in a specific location. 2. Prior to grubbing or topsoil stripping or pavement removal, place silt sack catch basin protection in all existing catch basins adjacent to the work area and in the location shown on the drawings. Although installation of this measure can be phased according to the construction schedule, silt sack catch basin protection must be in place prior to any work in a specific location. 3. Prior to any earthwork operations, install temporary siltation sump/filtration dams, swales with check dams, and construction entrance in the locations shown on the plans. These measures may be installed in phases according to the construction schedule, but must be completed prior to earthwork operations in the adjacent work area. 4. Damaged or loose strawbales and silt fence shall be replaced as necessary to maintain their function of controlling erosion and siltation. Damaged or broken down check dams and filtration dams shall be replaced immediately. Construction entrance and silt sack catch basin protection shall be replaced as necessary to maintain its function of controlling erosion and siltation to the work area. 5. Remove any accumulation of silt or soil build-up behind strawbales, silt fence, check dams, and filtration dams as it occurs. Remove accumulations of silt and soil build-up from the siltation sumps when it is approximately 18 inches deep. Replace the gravel filter on the inside of the filtration dams when it becomes clogged with silt or does not permit free drainage of stormwater through it, whichever occurs first. 6. Throughout excavation, filling, and grading operations, in addition to drainage swales, check dams, siltation sumps/filtration dams, and other items shown on the drawings, the Contractor shall take other necessary precautions, including installation of temporary drainage swales, siltation sumps/filtration dams, check dams, strawbales, silt fences, and temporary pipe, to direct and control drainage from disturbed areas on the site so that erosion and siltation is minimal. In addition, no erosion or discharge of silt or larger particles shall occur in areas to remain undisturbed or onto adjacent properties. 7. Remove all erosion control measures, including tree protection, strawbales, silt fence, siltation sumps and check dams, only when construction is completed, upland surfaces are stabilized and the piped drainage system is fully operational and it has been approved to do so. 8. BMPs to be used for infiltration after construction shall not be used as BMPs during construction. 9. Soil and other materials shall not be stockpiled or redistributed either temporarily or permanently, in locations or in such a manner as would casue suffocation of tree roots systems. 10. Topsoil shall be stripped from disturbed areas, stockpiles in approved areas and stabilized with temporary vegetative cover if it is to be left for more than thirty (30) calendar days; perimeter sediment controls shall be installed around each area of stockpiled topsoil. 11 11. Soil stockpiles must be stabilized or covered at the end of each workday. Stockpile side slopes shall not be greater that 2:1. All stockpiles shall be surrounded by sediment controls. 12. A tracking pad shall be constructed at all entrance/exist points of the site to reduce the amount of soil carried onto roadways and off the site. 13. All graded areas within and beyond the Street Right-of-Way shall be covered with four (4") inches of topsoil and planted with a temporary native species of vegetative cover, sufficient to prevent erosion; 14. Temporary seeding, mulching or other suitable stabilization methods shall be used to protect exposed soil areas during construction; as feasible, natural vegetation shall be retained and protected; during the months of October through March, when seeding may be impractical, an anchored mulch or sod shall be applied as approved by the Planning Board or by its Designee; diversions and/or prepared outlets may be required in critical areas during construction. 15. Permanent seeding shall be undertaken in the spring from March through May, and in late summer and early fall from August to October 15. During the peak summer months and in the fall after October 15, when seeding is found to be impractical, appropriate temporary mulch shall be applied. Permanent seeding may be undertaken during the summer if plans provide for adequate mulching and watering and is approved by the Landscape Architect. 16. Permanent vegetation and erosion control structures, as necessary, shall be installed preferably immediately after construction is completed but otherwise no later than the first full spring season immediately thereafter; they shall comply with the erosion and sedimentation vegetative practices recommended by the U.S. Soil Conservation Service; 17. Native species shall be used for re-vegetation; 18. Slopes (greater than 3:1) shall be protected from erosion by limiting clearing of these areas in the first place or, where grading is unavoidable, by providing special techniques to prevent upland runoff from flowing down a steep slope and through immediate stabilization to prevent gullying. Offsite runoff shall be diverted from highly erodible soils and steep slopes to stable areas. 19. Interim and permanent stabilization measures shall be instituted on a disturbed area immediately after construction activity has temporarily or permanently ceased on that portion of the site. 20. Temporary sediment trapping devices must not be removed until permanent stabilization is established in all contributory drainage areas. 21. All temporary erosion and sediment control measures shall be removed after final site stabilization. Disturbed soil areas resulting from the removal of temporary measures shall be permanently stabilized within 30 days of removal. 12 If the Contractor anticipates deviations from the above procedures, he shall obtain written approval from the Engineer prior to proceeding. EROSION AND SEDIMENT CONTROLS The Erosion and Sediment Controls represent the suggested best management practices proposed for the project. The Contractor's approach to controlling stormwater runoff from the site may vary; however they must update this SWPPP to reflect the changes and implement appropriate corresponding erosion control measures. The use of erosion and sediment controls are mandatory and must be employed to minimize impacts to adjacent areas during construction. If sediment escapes the construction site, off site accumulations of sediment must be removed at a frequency sufficient to minimize off-site impacts. The control practices which are required to minimize stormwater pollution during construction must remain functional until disturbed areas have been stabilized. Erosion control products are to be installed and maintained in accordance with manufacturer's specifications and good engineering practices. The most important aspects of controlling erosion and sedimentation are limiting the extent of drainage structures. These fundamental principles will be the key factors in the contractor's control of erosion on the project site. If appropriate, the contractor will construct temporary diversion swales and settling basins or use a settling tank. If additional drainage or erosion control measures are needed, they will be located up-gradient from the hay bales and silt fences. The contractor is responsible for the maintenance and repair of all erosion control devices on- site. All erosion control devices will be regularly inspected. At no time will silt-laden water be allowed to enter sensitive areas (wetlands, streams, and drainage systems). Any runoff from disturbed surfaces will be directed through a sedimentation process prior to being discharged to the existing on site drainage system. The contractor will establish a staging area on a lot to be disturbed for the overnight storage of equipment and stockpiling of materials. In the staging area, the contractor will have a stockpile of materials required to control erosion on-site to be used to supplement or repair erosion control devices. These materials will include, but are not limited to hay bales, silt fence, erosion control matting, and crushed stone. As mentioned previously, erosion and sedimentation controls will be employed to minimize the erosion and transport of sediment into resource areas during the earthwork and construction phases of the Project. Erosion and sedimentation control measures will be installed prior to site excavation or disturbance and will be maintained throughout the construction period. The contractor is responsible for erosion control on the site and will utilize supplemental erosion control measures to supplement the erosion controls shown on the plans prepared for this Stormwater Pollution Prevention Plan (SWPPP)to work with his day to day operations at the 13 site. Primary erosion control techniques proposed include hay bale barriers, silt fence barriers, inlet sediment traps, a stabilized construction entrance, temporary diversion channels, and temporary sedimentation ponds when applicable. A detailed description of each technique is discussed below. During the growing season, slope stabilization will be achieved by applying topsoil followed by seeding and mulching as soon as final grades are achieved. Organic mulching, jute netting, geo-textiles, or a combination will be used to stabilize slopes completed outside of the growing season. 2.1.1 Best Management Practices (BMPs) Silt Fence Hay Bale Barriers Erosion control barriers (silt fences or hay bale dike) will be installed prior to the start of construction. These barriers will remain in place until all tributary surfaces have been fully stabilized. Hay bale barriers will be placed to trap sediment transported by runoff before it reaches the drainage system or leaves the construction site. In areas where high runoff velocities or high sediment loads are expected, silt fencing may be installed adjacent to the hay bale barriers. This semi-permeable barrier made of a synthetic porous fabric will provide additional protection. The silt fences and hay bale barrier will be replaced as determined by periodic field inspection. The underside of hay bales will be kept in close contact with the earth and reset as necessary. Hay bale barriers and siltation fences will be maintained and cleaned until slopes have healthy stands of grass. Drain System Protection Silt Sack sediment traps supplemented with hay bale erosion checks will be installed at drainage structures and maintained and cleaned until slopes have healthy stands of grass. Catch basins, drain manholes, storm drain pipes, water quality inlets, and detention basins will be cleaned of sediment and debris after the completion of construction. Sediment collected in structures will be disposed of properly and covered, if stored on-site. • Hay bale check dams will be used on roadways to divert runoff onto stabilized areas. • Until tributary areas are stabilized, catch basin inlets will be filtered with a Silt sacks. if intense rainfall is predicted before all tributary areas are stabilized, erosion control measures will be reinforced for the duration of the storm. Downstream areas will be inspected and any sediment removed at the end of the storm. • Unfiltered water will not be allowed to enter pipes from unstabilized surfaces. • Trench excavation will be limited to the minimum length required for daily pipe installation. All trenches will be backfilled as soon as possible. The ends of pipes will be closed nightly with plywood 14 • During construction of the site, slit-laden waters should be intercepted prior to reaching catch basins. Any gross depositions of materials on paved surfaces will be removed by sweeping. • All paved areas will be swept on a weekly basis, as permitted by weather, during the construction period. • Catch basins should be inspected monthly and cleaned in anticipation of the winter season in November and at the same time the roads are swept in the spring. Diversion Channels Diversion channels may be used to intercept and divert runoff from slopes that are exposed during construction. These diversions will minimize the development of concentrated runoff down slopes, which could produce gully erosion. Diversions will also be used to collect runoff from construction areas and convey it to temporary sediment basins or traps. Temporary diversions will remain in place until slopes are stabilized or graded level. If vegetation of the diversion channel is required to avoid erosion of the channel, the channel will be temporarily stabilized to ensure viability of the grass seed. Temporary Sediment Ponds Temporary sediment ponds/basins will be constructed either as excavations or bermed water detention structures, depending on grading, that will retain runoff for a sufficient period of time to allow suspended soil particles to settle out prior to discharge. These temporary basins will be located at low points on the site and will receive runoff from temporary diversion swales. Discharge points from sediment basins will be stabilized to minimize erosion. The bottom of sediment basins will be cleaned periodically, with the sediment removed to a secure location to prevent siltation of natural waterways. If the location of a temporary sediment basin coincides with a permanent detention or infiltration system, the basin will be drained and any accumulated material will be removed before the basin is returned to service. Utility Construction The Contractor will construct utility trenches in a manner that will not direct runoff towards drainage system structures. 2.1.2 Stabilization Activities All disturbed surfaces will be stabilized a minimum of 21 days after construction in any portion of the project site is completed or is temporarily halted, unless additional construction is intended to be initiated within 21 days. The Contractor will not disturb more area than can be stabilized within 14 days unless the area is to remain active. The Contractor will not disturb more area than can be stabilized within the same construction season. Slope Stabilization 15 The smallest practicable area of land will be exposed at a time. Slopes greater than three-to- one (horizontal to vertical) will be stabilized with seed, organic mulch,jute fabric, or rip-rap, as appropriate, to prevent erosion during construction. After disturbed areas have been stabilized, the temporary erosion control measures will be removed and accumulated sediment will be removed and disposed of in an appropriate location. Disturbed areas will be stabilized with appropriate ground cover as soon as possible. After the removal of temporary erosion control measures, disturbed areas will receive a layer of topsoil for stabilization. Stabilized Construction Entrance Temporary stabilized construction entrances will be installed at the project site. The purpose of the construction entrance is to remove sediment attached to vehicle tires and to minimize sediment transport and deposition onto public road surfaces. The construction entrances will be composed of beds of crushed stone which will be replenished as necessary to maintain their proper function. 16 3.0 GOOD HOUSEKEEPING BMPS & ITEMS TO PREVENT ILLICIT DISCHARGE The following good house keeping practices will be followed onsite during the construction project: • An effort will be made to store only enough product required to do the job.

Site personnel will be instructed in these practices by the job site superintendent, who will also be responsible for seeing that these practices are followed. Solid and Construction Wastes All waste materials will be collected and stored in accordance with state and federal law in an appropriately covered container and/or securely lidded metal dumpster. All trash and construction debris from the site will be deposited in the dumpster. No construction waste materials will be buried on site, All personnel will be instructed regarding the correct procedures for waste disposal. All waste dumpsters and roll-off containers will be located in an area where the likelihood of the containers contributing to storm water discharges is negligible. If required, additional BMPs must be implemented, such as sandbags around the base, to prevent wastes from contributing to storm water discharges. Sanitary Wastes All sanitary waste will be collected from the portable units a minimum of three times per week by a licensed portable facility provider in complete compliance with local and state regulation. All sanitary waste units will be located in an area where the likelihood of the unit contributing to storm water discharges is negligible. If required, additional BMP's must be implemented, such as sandbags around the base, to prevent wastes from contributing to storm water discharges. 3.2 WASHOUT AREAS The Contractor will provide wheel wash stations and concrete washout areas at the site as described below. 18 I Wheel Wash Stations The Contractor will provide wheel wash stations adjacent to the construction entrance which lead directly to a public way or portions of the site outside the limits of work Concrete Washout Trucks will be allowed to washout or discharge surplus concrete or drum wash water on the site, but only in specifically designated diked and impervious washout areas which have been prepared to prevent contact between the concrete wash and stormwater. Waste generated from concrete wash water shall not be allowed to flow into drainage ways, inlets, receiving waters or highway right of ways, or any location other than the designated concrete washout. Waste concrete may be poured into forms to make riprap or other useful concrete products. Proper signage designating the "concrete washout" shall be placed near the facility. The hardened residue from the concrete washout diked areas will be disposed of in the same manner as other non-hazardous construction waste materials or may be broken up and used on site as deemed appropriate by the Contractor. Maintenance of the washout is to include removal of hardened concrete. Facility shall have sufficient volume to contain all the concrete waste resulting from washout and a minimum freeboard of 1 foot. Facility shall not be filled beyond 95% capacity and shall be cleaned out once 75% full unless a new facility is constructed. 3.3 VEHICLE AND EQUIPMENT FUELING Areas will be designated on site, outside of any resource or buffer area, to refuel or maintain equipment used on site. Equipment fuel storage and refueling operations will be in an upland area at a horizontal distance greater than 100 feet from the boundaries of the wetland resource areas. The fueling areas will include secondary containment. The fueling areas will be inspected and cleaned weekly. 3.4 SPILL PREVENTION AND CONTROL PLAN The Contractor will train all personnel in the proper handling and cleanup of spilled materials. No spilled hazardous materials or hazardous wastes will be allowed to come in contact with storm water discharges. If such contact occurs, the storm water discharge will be contained on site until appropriate measures in compliance with state and federal regulations are taken to dispose of such contaminated storm water. It shall be the responsibility of the job site superintendent to properly train all personnel in spill prevention and clean up procedures. In order to minimize the potential for a spill of hazardous materials to come into contact with storm water, the following steps will be implemented: 1. All materials with hazardous properties (such as pesticides, petroleum products, fertilizers, detergents, construction chemicals, acids, paints, paint solvents, cleaning solvents, additives for soil stabilization, concrete curing compounds and additives, etc.)will be stored in a secure location, with their lids on, preferably under cover, 19 when not in use. 2. During construction, liquid petroleum products and other hazardous materials with the potential to contaminate groundwater may not be stored or handled in areas of the site draining to an infiltration area, An "infiltration area" is any area of the site that by design or as a result of soils, topography and other relevant factors accumulates runoff that infiltrates into the soil. Dikes, berms, sumps, and other forms of secondary containment that prevent discharge to groundwater may be used to isolate portions of the site for the purposes of storage and handling of these materials 3. The minimum practical quantity of all such materials will be kept on the job site at all times. 4. A spill control and containment kit (containing, for example, absorbent materials, acid neutralizing powder, brooms, dust pans, mops, rags, gloves, goggles, plastic and metal trash containers, etc.)will be provided at the storage site. Catch basin inlet cover blankets and inflatable pipe plugs will be used to seal the openings in the outlet control structure and isolate product in the wet pond should a spill occur. 5. Manufacturers recommended methods for spill cleanup will be clearly posted and site personnel will be trained regarding these procedures and the location of the information and cleanup supplies. In the event of a spill, the following procedures should be followed: 1. All spills will be cleaned up immediately after discovery. 2. The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with the hazardous substances. 3. The project manager and the Engineer of Record will be notified immediately. 4. Spills of toxic or hazardous materials will be reported to the appropriate federal, state, and/or local government agency, regardless of the size of the spill. 5. If the spill exceeds a Reportable Quantity, the SWPPP must be modified within seven (7) calendar days of knowledge of the discharge to provide a description of the release, the circumstances leading to the release, and the date of the release. The plans must identify measures to prevent the recurrence of such releases and to respond to such releases. The job site superintendent will be the spill prevention and response coordinator. He will designate the individuals who will receive spill prevention and response training. These individuals will each become responsible for a particular phase of prevention and response. The names of these personnel will be posted in the material storage area and in the office trailer onsite. 3.5 ALLOWABLE NON-STORMWATER DISCHARGE MANAGEMENT Certain types of discharges are allowed under the NPDES General Permit for Construction 20 Activity, and it is the intent of this SWPPP to allow such discharges. These types of discharges will be allowed under the conditions that no pollutants will be allowed to come into contact with the water prior to or after its discharge. The control measures that have been outlined previously in this SWPPP will be strictly followed to ensure that no contamination of these non-stormwater discharges takes place. The following non-stormwater discharges that may occur from the job site include: • Discharges from fire-fighting activities • Fire Hydrant fleshings • Waters used to wash vehicles where detergents are not used • Water used to control dust in accordance with off-site vehicle tracking • Potable water including uncontaminated water line flushings • Routine external building wash down that does not use detergents • Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred (unless all spilled material has been removed) and where detergents are not used • Uncontaminated air conditioner compressor condensate • Uncontaminated ground water or spring water • Foundation or footing drains where flows are not contaminated with process materials such as solvents • Uncontaminated excavation dewatering • Landscape irrigation 3.6 STORMWATER TMDLS A portion of the project discharges to a Town storm drain system, which outlet to the Shawsheen River. The MassDEP has issued a final Total Maximum Daily Load (TDML) that establishes a waste load allocation for stormwater discharge for the Shawsheen River segment ID MA-83-01-2002- 24. The MADEP has listed as cause for impairment: ■ Fecal Coliform The SWPPP has taken the following measures to ensure that the pollutants from the site are consistent with the assumptions of the EPA-approved TMDL. • The SWPPP has instituted the above mentioned "Good Housekeeping BMPs" in Section 3.0, "Post-Construction BMPs" in Section 4.0, and "Operation and Maintenance Plan" in Section 4.1. 21 4.0 POST-CONSTRUCTION BMPS 4.1.0 Operations and Maintenance Plan See attached Operation and Maintenance Plan for Post-Construction BMPs. 22 5.0 INSPECTIONS & MAINTENANCE 5.1 INSPECTIONS The General Permit Conditions require routine inspections of the site and careful documentation of events and conditions. The following inspection activities will be completed by a qualified, designated site monitor. • Erosion control, sedimentation prevention, and stormwater management measures will be inspected at least once per week throughout the construction period. • All controls, outfalls, and potential problem areas will also be inspected within 24 hours of any storm exceeding 0.5 inches of precipitation. A log of inspection results will be maintained on-site and will include the name of the inspector, date, major observations, and necessary corrective measures. Built up sediment will be removed when it has reached one-third the height of the silt fence. All needed repairs or modifications will be reported to the contractors to permit the timely implementation of required actions. Where necessary repairs do not pose an immediate concern, repairs or modifications will be implemented within two (2) days of inspection. The SWPPP will be modified within seven days to reflect any modifications to measures as a result of inspection. A report summarizing the scope of the inspection, name(s) and qualifications of personnel making the inspection, the date(s)of the inspection, major observations relating to the implementation of the SWPPP, and actions taken will be made and retained as part of the SWPPP for at least three years after the date of the inspection. Weekly reports of maintenance and inspection activities will be maintained on-site, in conformance with the NPDES permit conditions. 5.2 MAINTENANCE The following maintenance practices will be used by the Contractor to maintain erosion and sediment controls. Maintenance activities will be documented on the Inspection Report Forms included in Appendix E. Erosion and sediment control measures and other protective measures must be maintained in effective operating condition. ➢ If site inspections indicate that BMPs are not operating effectively, maintenance must be performed as soon as possible and before the next storm event whenever practicable to maintain the continued effectiveness of the BMPs. If implementation before the next storm event is impracticable, the situation must be documented in the SWPPP and alternative BMPs must be implemented as soon as possible. 23 ➢ If existing BMPs need to be modified or if additional BMPs are necessary for any reason, implementation must be completed before next storm event whenever practicable. If implementation before the next storm event is impracticable, the situation must be documented in the SWPPP and alternative BMPs must be implemented as soon as possible. ➢ Pollution prevention measures must be maintained in good working order. If a repair is necessary, it will be initiated, if practicable, within 24 hours of report. ➢ Accumulated sediment within the catch basin inlet protection must be removed on a weekly basis. ➢ Maintenance and inspection of pollution prevention measures must be continued on the site for as long as a portion of the site remains disturbed. ➢ Stabilization measures will be initiated as soon as practicable on portions of the site where construction has temporarily or permanently ceased. This will occur in NO CASE more than 14 days after construction activities have temporarily or permanently ceased. ➢ If issues are identified at hazardous materials storage areas, corrective actions will be implemented immediately. If leaks or spills are identified procedures outlined in Section 3A will be followed. 5.3 CORRECTIVE ACTION LOG See Appendix F for Corrective Action Log's. 24 6.0 RECORD KEEPING AND TRAINING 6.1 RECORD KEEPING Records will be retained for a minimum period of at least 3 years after the permit is terminated. Any time the following activities occur the Grading and Stabilization Activities Log will be filled out (see Appendix 1): ➢ When major grading activities occur ➢ When construction activities temporarily or permanently cease on a portion of the site ➢ When an area is either temporarily or permanently stabilized 6.2 LOG OF CHANGES TO THE SWPPP This SWPPP must be modifies{ as necessary to: ➢ Ensure permit compliance when notified by EPA that the plan does comply ➢ Include additional or modified BMPs that correct problems identifies{ as a result of an inspection. Revisions must be completed with seven (7) calendar days following the inspection. ➢ Ensure the effectiveness of the SWPPP in eliminating or significantly minimizing pollutants from stormwater discharges from the site. ➢ Prevent the reoccurrence of release of a hazardous material or oil. ➢ Address a change in design, construction, operation, or maintenance which has or may have a significant effect on the potential for the discharge of pollutants, All modifications to the SWPPP must be recorded on the SWPPP Amendment Log included in Appendix G. 6.3 TRAINING Training sessions must be provided by the Contractor for construction personnel. The training will review specific BMPs used in the work are as well as reporting and response measures that may be needed by either construction personnel and/or inspectors to implement the SWPPP. Additionally, appropriate construction personnel will be trained in the operation and maintenance of equipment to prevent the discharge of oil/hazmat and spill response procedures. Training sessions will highlight known spills or releases and recently developed precautionary measures. See Appendix J for SWPPP Training Log. 25 7.0 FINAL STABILIZATION Permanent stabilization of the site will be accomplished through the installation of the final perennial vegetative cover on unpaved areas and areas not covered by permanent structures. The permanent vegetative cover must be established within 14 days after the construction activity in that portion of the site has permanently ceased. 26 8.0 CERTIFICATION AND NOTIFICATION I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted.

Standard 9: Long Term Operation and Maintenance Plan POST CONSTRUCTION PERIOD LONG-TERM POLLUTION PREVENTION PLAN Post-Construction BMP's for Water Quality and to Prevent Illicit Discharges Good housekeeping practices for long-term pollution prevention are a detailed below. - All material and waste products used for maintaining the site shall be stored inside,outside under cover,or placed in the dumpster if it is being disposed of. No post-construction vehicle washing shall occur on site. - Requirements for routine inspections and maintenance of stormwater BMPs are detailed below. - Spill prevention and response plans are detailed below. Provisions for maintenance of lawns,gardens,and other landscaped areas are detailed below. Storage of all fertilizers,herbicides,and pesticides shall follow the material storage requirements listed above. Use of all fertilizers,herbicides,and pesticides is detailed below. All pet waste shall be disposed of in the dumpster facilities. No septic system is on site. - Solid waste management shall be relegated to the disposal facilities placed on site. - Snow disposal and plow plans are detailed below, Winter salt and sand use are detailed below. - Street sweeping schedules are detailed below. - Provisions for prevention of illicit discharges to the stormwater management system are detailed below. - Training of staff involved with implementing the Long-Term Pollution Prevention Plan is detailed below. List of Emergency contacts responsible for implementing the Long-Term Pollution Prevention Plan are listed above in the Basic Information section. Several types of structural and non-structural water quality controls in various combinations are proposed to treat stormwater generated on the site.These measures include deep sump catch basins with hoods and stormwater treatment units. These Water quality treatment measures will result in the removal of total suspended solids(TSS)load in runoff prior to discharge from the site,consistent with DEP's TSS removal standard. The following best management practices are specified in the proposed development program to mitigate the increase in stormwater runoff from the site. BMPs Used ➢ Nyloplast Area Drains ➢ Underground Stormwater Storage Chambers Page 8 of 11 Date:July 2019 Project:Grogan's Field—Stor;nwater Management Plan Post-Development activities 1. The underground flood storage chambers and the inlet/outlet pipes shall be inspected a minimum of hvice/year for signs of accumulated water or debris. Implement appropriate corrective action if any issues are discovered during the inspection. Cleaning shall be in strict conformance with the manufacturer's recommendations,which are attached to and made pant of this Long Term Operation and Maintenance Plan. 2. All sediments removed from the site drainage facilities shall be disposed of properly and in accordance with all applicable local and state regulations. 3. All vegetated slope areas on the site shall be stabilized following completion of construction and maintained to control erosion. Any disturbed areas shall be re-seeded and stabilized by the application of jute mesh if the slope exceeds 3 feet horizontal to 1 foot vertical 4. Snow storage at the site will be managed to prevent blockage of the area drain and other elements of the storm drainage system. 5. Snow shall not be dumped into any waterbody,pond,wetland resource area,wet basin or detention basin. 6. Sand and debris deposited on vegetated and paved areas at the site shall be cleared from the site and disposed of at the end of the snow season,no later than May 15. . 7. Snow should be trucked off-site to an approved disposal area operated in accordance with MADEP Snow Management Standards when there is insufficient space for snow storage at the site. All structural BMP's and maintenance responsibilities as identified on the site plans and within this document will be owned and maintained by the owner of the property and shall run with the title of the property.
