(Site Plans) • 2022 Construction General Permit - "National Pollutant Discharge Elimination System General Permit for Discharges from Construction Activities (as modified)", https://www.epa.gov/npdes/2022-construction-general-permit-cgp#2022cgp DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 2 Preliminary DRAFT June 9, 2023 1.4 PURPOSE AND TYPES OF SOIL DISTURBING ACTIVITIES The Applicant is proposing to construct of a large-scale ground mounted photovoltaic solar project within a ±10.66-acre portion of fenced-in area hereinafter referred to as the Wakeby Road Solar Project (the Project). The Project is located within ±19.32-acres of land identified as 810 Wakeby Road property. This property is located in the village of Marstons Mills within the Town of Barnstable, Massachusetts shown as Parcels 4, 5 and 52 on Barnstable Assessor Map 13. The Project presently consists of a mostly cleared/disturbed area. Pockets of low growing brush and young trees scatter the interior while light to moderate tree cover exists along the edges of the parcels’ boundaries. The existing topography is variable but generally slopes down on all sides to several natural depressions or excavated depressions within the center. These depressions are the result of the parcels’ historical use as a sand and gravel quarry. Existing soils consist of silt loam, loamy coarse sand, coarse sand, as well as sand and gravel pits. Any vegetation within the limit of work will be cleared and grubbed as needed for the construction of the solar array as well as the installation of three (3) infiltration basins and associated infrastructure (Refer to the Site Plans – Site Development Plans for 810 Wakeby Road Solar Project). The Project layout and drainage has been designed to utilize the existing topography to the extent possible. The interior of the Project will be graded to a maximum of 15% slope while portions of the area surrounding the Project will be graded to a maximum of 50%. Additionally, grading activities will include the construction of an earthen berm for screening purposes and the gravel access road along the south, west, and northern perimeter of the Project as well as excavation of stormwater infiltration basins. The proposed stormwater system is primarily an open drainage system comprised of three (3) infiltration basins, which will fully capture/infiltrate runoff generated on the site by a 100-year storm event. These basins were positioned in natural low areas located in the northern, central, and southern portions of the Project. Intermediate erosion controls have been proposed throughout the Project as well as at the base steep slopes (≥30%). All disturbed areas will be seeded as required to provide stabilization in accordance with the requirements set forth within the 2022 Construction General Permit. A wetland review of the Site was completed by Wendell Wetland Services on October 23, 2019, and no wetlands were identified on the three parcels proposed for the solar development. The Town of Barnstable Conservation Commission issued a negative Determination of Applicability (RDA) for the project on December 3, 2019. The DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 3 Preliminary DRAFT June 9, 2023 MassDEP Priority and Estimated Habitats MassGIS shows the Site is not within a Priority Habitats of Rare Species or Estimated Habitats of Rare Wildlife Zone (NHESP). The project does not lie within a Flood Zone based upon a review of available Federal Emergency Management Agency (FEMA) data/mapping. The Project is subject to the Massachusetts Stormwater Management Policy, and as such a Stormwater Management/Drainage Analysis Report which addresses the stormwater standards of the Town of Barnstable, and the Massachusetts Department of Environmental Protection has been prepared as part of the permitting and design process. 1.5 SITE AREA AND RUNOFF COEFFICIENT ESTIMATES The total acreage of the three properties which compose 810 Wakeby Road (Parcels 4, 5 and 52) is ±19.32-acres, of which, greater than ±10.66-acre will be included as part of construction activities including, but not limited to, grading required for construction of earthen berm for screening, stormwater infrastructure, grading for construction of access road, installation of solar panel arrays and their corresponding electrical systems, underground/overhead utilities, fencing, and vegetative screening. The Project will be situated on land previously cleared/disturbed for use as a sand and gravel quarry. The solar array has been designed to follow existing topography to the maximum extent practicable with proposed grading needed to stabilize slopes at a grade which permits ground mounted solar installation. Existing vegetated ground cover, beneath, around and between the panels will be enhanced following seeding as required to provide stabilization in accordance with the requirements set forth within the 2022 Construction General Permit. The only increase in impervious area is associated with the proposed equipment pads, which are proposed to be located on the northern and southern points of the Project. The size of the proposed pads is negligible when compared to the overall size of the surrounding grassed area. Although clearing existing low growing brush within the Project area will result in a marginal increase to the existing runoff coefficient, stormwater measures are being proposed which will fully capture/infiltrate runoff generated on the site by a 100-year storm event. As part of the stormwater design, three (3) infiltration basins are proposed in natural low areas located in the northern, central, and southern portions of the Project. The stormwater facilities are designed to account for any increase in run-off/volume and replicate pre-development runoff characteristics of the site. DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 4 Preliminary DRAFT June 9, 2023 1.6 NATURE AND SEQUENCE OF MAJOR ACTIVITIES A general sequence of construction for the site work is as follows: 1) Stake limit of work to accurately define the limits of work for the access roads, solar field, site grading, utilities, and stormwater facilities. 2) Install perimeter erosion control measures as shown on plans. 3) Install crushed stone tracking pads at the start of the access road. 4) Grade access road as required to facilitate construction activities throughout the site. 5) Prepare contractor staging/laydown area for temporary parking, storage, wheel wash area, concrete wash-out, and mobile fueling areas. 6) Perform tree clearing activities and till/grub areas within the proposed limits of work as required to eradicate existing vegetation. 7) Grade the site to attain the elevations and slopes shown on the plans. Grading activities should be avoided during extremely wet conditions to minimize soil compaction, deep rutting, and soil smearing. 8) Install stormwater measures, including grassed swales once rough grading is complete. If necessary, provide temporary protective measures, which may include barriers and/or silt sacks until site is stabilized and vegetated. Intermediate erosion controls should be installed prior to the installation of the solar array racking system. 9) Use disks, tillers, or harrows to break up the surface where soil has become compact ed during construction activities in order to create viable seed beds. 10) Install vegetative screening and, as needed, organic, clean top soil to improve plant health and longevity 11) Initiate the installation of stabilization measures immediately in any areas of exposed soil more than five acres where construction activities have permanently ceased or will be temporarily inactive for 14 or more calendar days. Complete the installation of measures as soon as practicable, but no later than (7) calendar days after stabilization has been initiated. Oats will be used for a spring or summer seeding, winter wheat for a fall seeding. This cover crop will establish quickly, providing additional erosion control throughout construction, along with protection of final native vegetation during its establishment period. 12) Install perimeter fencing leaving sections open for ingress/egress, temporary fencing shall be used to maintain site security. DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 5 Preliminary DRAFT June 9, 2023 13) Install solar field array and electrical facilities on site. Work involving foundation pile driving and trenching shall be staged to concentrate work in phases, to reduce site disturbance. Seed and mulch any disturbed areas as they are completed. 14) Once site construction is complete, permanent seeding will be applied by broadcasting. 15) To assure rapid stabilization, supplement seeding for areas where coverage is less than 70% uniform cover of vegetation. 16) Once the site is permanently stabilized at 70% uniform cover of vegetation or more, remove all temporary erosion and sediment control devices. 1.7 NAME OF RECEIVING WATERS There are no direct untreated storm water discharge to any water body, wetland, pond, river, stream, or buffer zone on or adjacent to the site. All stormwater runoff from new impervious areas will be directed toward a detention basin. 1.8 SENSITIVE AREAS TO BE PROTECTED a) WETLANDS There are no bordering vegetated wetland systems located on the Site. b) RIVERFRONT AREA There is no Riverfront Area on the Site. c) ENDANGERED SPECIES Based on the US Fish and Wildlife Service research, the area is mapped for the Northern Long-Eared Bat. However, a federally designated critical habitat (Hibernacula or Maternity Roost Trees) is not located on the project site. The proposed Project location is more than 5 miles from any known Hibernacula or Maternity Roost Tree locations. The resulting distance from the project to the closest critical habitat, coupled with the fact that the project is designed to fully capture/infiltrate runoff generated on the site by a 100- year storm event demonstrates that the project/stormwater will not result in adverse impacts to the listed species. 2.0 EROSION AND SEDIMENT CONTROLS 2.1 GENERAL STABILIZATION PRACTICES Detailed erosion control plans, notes and details are included in the Site Plans. The ±10.66-acres that comprise the Project will require regrading for earthen berm, stormwater infiltration basins, site access road, and equipment pads prior to installation of the solar racking/modules, as shown on the Site Plans (Refer to Site Plans by Atlantic DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 6 Preliminary DRAFT June 9, 2023 Design Engineers, Inc.). The Project will be installed in a manner to reestablish the vegetated ground cover, beneath, around and between the panels as quickly as possible. Portions of the site that are disturbed during construction will be revegetated by spreading non-invasive local, native, naturalized herbaceous seed mix as required to ensure the disturbed areas will stabilize quickly (Refer to Site Plans by Atlantic Design Engineers, Inc.). Maintaining the existing vegetation and reseeding the site in this manner will minimize potential for erosion. As previously mentioned, erosion control measures (silt sock, or approved equal) will be in place and maintained at the proposed limit of work throughout construction, until vegetation has stabilized, in order to protect the surrounding area. As depicted/detailed on the Site Plans, intermediate erosion controls have been proposed throughout the Project as well as at the base steep slopes (≥30%). Erosion control barriers will be repaired immediately if there are any signs of damage, erosion, or sedimentation. Accumulated sediment deposits will be removed after each significant storm event, or when deposits reach approximately one-half the height of the barrier. Erosion will be minimized by protecting exposed soils from rainfall impact and overland flow, and will be stabilized via rolled erosion control products or mulching. The following general soil erosion and sedimentation control practices will be applied during construction operations of all phases to protect local water quality. 1. The BMP’S used to control erosion and sedimentation shall be imple mented as follows: A. Erosion and sediment control practices will be constructed or installed before land disturbing construction activities begin in accordance with the plan developed for this site. B. Erosion and sediment control practices shall be maintained until final stabilization. C. Final stabilization activity shall commence when land disturbing activities cease and final grade has been reached on any portion of the site. D. Temporary stabilization will commence as soon as possible after land disturbance ceases. Temporary stabilization activity shall commence when land disturbing construction activities have temporarily ceased and will not resume for a period exceeding 14 calendar days. E. If disturbing five acres or less at a time, complete the installation of stabilization measures as soon as practicable, but no later than 14 calendar days after stabilization has been initiated. F. If disturbing more than five acres at a time, complete the installation of stabilization measures as soon as practicable, but no later than seven (7) DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 7 Preliminary DRAFT June 9, 2023 calendar days after stabilization has been initiated. G. BMP’s that are no longer necessary for erosion and sediment control shall be removed. 2. Temporary erosion/sediment control barriers shall be installed around the perimeter of the construction site prior to commencement of site disturbance in accordance with MADEP standards. Sediment deposits must be removed when the deposits have accumulated to 1/2 the height of the barrier. Torn, degraded, trampled, or otherwise compromised erosion/sediment control barriers will be properly replaced. As previously stated, double erosion control barriers will be placed within 30 feet of the wetland system. 3. A stone tracking pad, at the construction entrance, (50 feet long min) shall be installed, underlain by geotextile fabric. The tracking pad will consist of 1 - 2" clear or washed stone, installed and maintained to a minimum thickness of 6-inches dependent on site soil conditions. The tracking pads will be maintained by scraping or top-dressing with additional aggregate. If conditions on the site are such that the sediment is not removed from vehicle tires by the tracking pad, then tires shall be washed utilizing pressurized water before entering a public road. Stone tracking pad and tire washing shall be constructed and maintained in accordance with MADEP standards. Final location of the tracking pad shall be coordinated with the contractor and owner. 4. A staging and parking area shall be designated for material laydown. Storage of all equipment and construction materials shall be stored according to all federal and state standards. 5.

Concrete washout and vehicle fueling area shall be implemented in accordance with MADEP standards. 6. A temporary bale sediment barrier will be utilized to intercept sediment-laden sheet flow, if needed, consisting of a row of entrenched and anchored hay or straw bales. At a minimum, sediment bale barriers shall be placed in a single row, lengthwise on the contour, with the ends of adjacent sediment bale barriers tightly abutting one another. The holes between bales shall be chinked (filled by wedging) with straw, hay or equivalent material to prevent water from escaping between the bales. 7. Damage to any existing utilities and services indicated to remain shall be the responsibility of the contractor; contractor shall repair and/or replace in kind. DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 8 Preliminary DRAFT June 9, 2023 8. Dust control measures shall be implemented during construction, including but not limited to watering down exposed dirt and gravel access roads, if needed. 9. Existing trees or vegetation indicated to remain shall be avoided and fenced off appropriately to avoid any confusion, if applicable. Contractor shall avoid damaging any existing vegetation to minimize potential erosion. 10. No dewatering activities are planned. If dewatering becomes necessary, it shall be conducted in accordance with MADEP standards. Contractor to install tem porary settling basin or other appropriate best management practice as necessary and locate in upland areas. Dewatering directly into field tiles, storm sewers or off-site wetlands is prohibited. 11. Permanent or temporary soil stabilization must be applied within 14 calendar days of the end of active soil disturbance. All temporary seeding activities shall be implemented in accordance with MADEP standards. 12. The contractor shall inspect erosion control measures weekly until construction is complete and the site is stabilized. Inspections must be conducted within 24 hours after a rain event of 0.25 inches or more. Necessary repairs or replacements of practices must be made within 24 hours of inspection. Weekly written reports of all inspections must maintained at the construction site. 13. The temporary erosion measures shall remain in place until the site is permanently stabilized at a minimum 70% uniform cover of vegetation. 14. All materials and stockpiles shall be stored on level areas outside of any flood zones, wetlands, or buffer zone areas, if applicable. All stockpiles shall be surrounded by hay bales, shall have side slopes no greater than 30% and shall be seeded or stabilized if left undisturbed for two weeks or more. 15. Any slope steeper than 3:1 shall be equipped with slope stabilization fabric or erosion control matting. 16. Additional erosion control measures shall be instituted as conditions warrant or as directed by the engineer and/or the town. 17. Material stockpiles shall not be located within the path of existing or proposed watercourses (either temporary or permanent) or those areas subject to storm water flow. 18. All disturbed or exposed areas subject to erosion, which remain disturbed but inactive for at least thirty days, shall receive temporary seeding in accordance with the Massachusetts erosion and sediment control guidelines. In all cases, stabilization measures shall be implemented as soon as possible in accordance with the Massachusetts erosion and sediment control guidelines. DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 9 Preliminary DRAFT June 9, 2023 19. Earthwork activity on the site shall be done in a manner such that runoff is directed away from abutting structures, property, etc. 20. The contractor shall keep on site at all times additional hay bales and extra siltation fencing for installation at the direction of the engineers or the town to mitigate any emergency control. 21. The contractor shall be responsible for the siting, relocation and augmentation of erosion control devices as the project progresses and the site drainage conditions change. 22. The contractor shall minimize the area of disturbed soil. Efforts shall be made to limit the time of exposure of disturbed areas. 2.2 STRUCTURAL PRACTICES/OPERATION & MAINTENANCE Erosion Control Barriers Erosion control barriers (sediment logs, haybales, silt fence, etc.) should be inspected weekly, promptly after each major rainfall event (>0.25 inches per 2022 CGP) and at least daily during prolonged rainfall. Remove built up sediment and debris from erosion barriers/sediment logs and “silt socks” when accumulation has reached 50% of the structure height and immediately replace any erosion and sediment control structures that are damaged. (Additional erosion and sediment control barriers shall be stored onsite). Stormwater Basins At a minimum shall be inspected after every major storm event (>0.25 inches per 2022 CGP) for the first six (6) months, then in the spring and fall of every year, thereafter. Note how long water remains standing in basin after a storm; standing water within the basin >72 hours after storm events should be immediately addressed. Also, within the basin, check for signs of differential settlement, cracking, erosion, leakage in embankments, tree growth in embankments, condition of riprap, sediment accumulation and the health of the turf. Stormwater basins shall be mowed a minimum of twice per year. Grass clippings and accumulated organic matter should be removed from the basin to a non-sensitive area. Repairs and reseeding should be done as required. Sediment and debris should be removed manually when stormwater basin is thoroughly dry, a minimum of once per year or when the sediment level reaches a depth of three inches (3”) in the basin or half an inch (1/2”) in the low flow drain. 2.3 STABILIZATION PRACTICES DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 10 Preliminary DRAFT June 9, 2023 Cover Crop A cover crop shall be provided within the limits of construction. Cover crop shall be comprised of non-invasive local, native, naturalized herbaceous species (annual ryegrass). The cover crop is an annual grass species that germinates quickly and will reduce the risk of on-site soil erosion and deter the establishment of weeds prior to permanent seeding. All disturbed areas shall be seeded with cover crop prior to (date TBD) regardless of construction status. Dust Control Dust control will be maintained by sprinkler or water truck as necessary during grading operations to minimize sediment transport and to maintain acceptable air quality conditions. Repetitive treatment will be done as needed until soils are paved or otherwise stabilized. Stabilized Construction Entrance A crushed stone tracking pad will be provided at the entrances to the site to help reduce vehicle tracking of sediments. 2.4 STORMWATER MANAGEMENT/BMP’s As previously mentioned, new impervious areas are limited to the proposed equipment pads. The Project’s drainage has been designed to utilize the existing topography to the extent possible. The interior of the Project will be graded to a maximum of 15% slope while portions of the area surrounding the Project will be graded to a maximum of 50%. Additionally, grading activities will include the construction of an earthen berm for screening purposes and the gravel access road along the south, west, and northern perimeter of the Project as well as excavation of stormwater infiltration basins. The proposed stormwater system is primarily an open drainage system comprised of three (3) infiltration basins, which will fully capture/infiltrate runoff generated on the site by a 100-year storm event. These basins were positioned in natural low areas located in the northern, central, and southern portions of the Project. The stormwater management system for the project consists of on-site Best Management Practices (BMP’s) to minimize any impacts the proposed development may have on stormwater quality. The proposed stormwater management system depicted on the drawings was prepared by others as part of the permitting and design which was reviewed and approved by the Town of Barnstable. The following BMP’s have been incorporated DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 11 Preliminary DRAFT June 9, 2023 into the design to treat/handle the stormwater runoff generated by the site: • Erosion Control Barriers • Stabilized Construction Entrance • Proposed Stormwater Basins The location and details of the Stormwater BMPs and Erosion Control Measures are provided in Appendix F. 3.0 GOOD HOUSEKEEPING 3.1 MATERIAL HANDLING AND WASTE MANAGEMENT Waste Materials All non-hazardous waste materials will be collected and disposed of in metal trash dumpsters in accordance with State/Local standards. Dumpsters will have a secure watertight lid, be placed away from stormwater conveyances and drains, and meet all local and state solid-waste management regulations. Only trash and construction debris from the site will be deposited in the dumpsters. All personnel will be instructed, during tailgate training sessions, regarding the correct procedure for disposal of trash and construction debris. Notices that state these practices will be posted in the office trailer and the individual who manages day-to-day site operations will be responsible for seeing that these practices are followed. All non-hazardous waste disposal is to be done in accordance with local, state, and federal regulations. Hazardous Waste All hazardous waste materials such as oil filters, petroleum products, paint, and equipment maintenance fluids will be stored in structurally sound and sealed shipping containers in the hazardous-materials storage area and segregated from other non-waste materials. Secondary containment will be provided for all materials in the hazardous materials storage area and will consist of commercially available spill pallets. Additionally, all hazardous materials will be disposed of in accordance with federal, state, and municipal regulations. Hazardous waste materials will not be disposed of into the on-site dumpsters. All personnel will be instructed, during tailgate training sessions, regarding proper procedures for hazardous waste disposal. Notices that state these procedures will be posted in the office trailer and the individual who manages day-to-day site operations will be responsible for seeing that these procedures are followed. DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 12 Preliminary DRAFT June 9, 2023 Sanitary Waste Temporary sanitary facilities (portable toilets) will be provided at the site. Locate the toilets away from concentrated stormwater flow paths, stormwater conveyances and drains, and away from traffic flow areas and place collection pans underneath as secondary containment. Recycling Wood pallets, cardboard boxes, and other recyclable construction scraps will be disposed of in a designated dumpster for recycling in accordance with State/Local requirements. The dumpster will have a secure watertight lid, be placed away from stormwater conveyances and drains and meet all local and state solid-waste management regulations. Only solid recyclable construction scraps from the site will be deposited in the dumpster. All personnel will be instructed, during tailgate training sessions, regarding the correct procedure for disposal of recyclable construction scraps. Notices that state these procedures will be posted in the office trailer, and the individual who manages day-to-day site operations will be responsible for seeing that these procedures are followed. 3.2 ESTABLISH PROPER BUILDING MATERIAL STAGING AREAS Combined Staging Area Construction equipment and maintenance materials will be stored at the combined staging area and materials storage areas. A watertight shipping container will be used to store hand tools, small parts, and other construction materials. Nonhazardous building materials such as packaging material (wood, plastic, and glass), and construction scrap material (brick, wood, steel, metal scraps, and pipe cuttings) will be stored in a separate covered storage facility adjacent to the shipping container. All hazardous-waste materials such as oil filters, petroleum products, paint, and equipment maintenance fluids will be stored in structurally sound and sealed containers under cover within the hazardous materials storage area. Large items, such as framing materials and stockpiled lumber, will be stored in the open in the storage area. Such materials will be elevated on wood blocks to minimize contact with runoff. 3.3 ESTABLISH PROPER EQUIPMENT/VEHICLE FUELING AND MAINTENANCE PRACTICES Vehicle Equipment Fueling and Maintenance Several types of vehicles and equipment will be used on-site throughout the project, including graders, scrapers, excavators, loaders, rollers, trucks and trailers, backhoes, and DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 13 Preliminary DRAFT June 9, 2023 forklifts. All major equipment/vehicle maintenance will be performed off-site. When vehicle fueling must occur on-site, the fueling activity will occur in the staging area in accordance with the following procedures: • Contractors will not store fuel for refueling construction vehicles onsite. • Spill kits will be stored in readily accessible areas for quick use in the event that they are needed by the construction or re-fueling personnel. • All fuel nozzles will be equipped with functional automatic shut-off valves. Drip trays and sorbent pads will be used during on-site re-fueling to minimize spills. Prior to departure of any fuel tank truck, all outlets on the vehicle will be examined by the driver for leakage and tightened, adjusted, or replaced to prevent leaking while in transit. • A drip pan (minimum 15-gallon capacity) will be placed under the construction equipment being fueled. • A spill kit consisting of absorbent, spill-cleanup materials and overpack drum will be available at the fueling area. Only minor equipment maintenance will occur on-site. All equipment fluids generated from maintenance activities will be disposed of into designated drums stored on spill pallets in accordance with Section 3, Part 3.1. Absorbent, spill-cleanup materials and spill kits will be available at the combined staging and materials storage area. Drip pans will be placed under all equipment receiving maintenance and vehicles and equipment parked overnight. 3.4 CONTROL EQUIPMENT/VEHICLE WASHING All equipment and vehicle washing will be performed off-site. In addition, all earth moving construction vehicles will be washed down off-site prior to entering the property to remove plants, seeds and other materials in order to minimize the potential for invasive species being carried onto the Site. High pressure washing is preferred along with a visual inspection for visible soils, vegetation or other debris on each new vehicle entering the Site during construction. 3.5 SPILL PREVENTION A Spill Prevention Control and Countermeasures Plan, if available, is to be incorporated into this SWPPP. At a minimum, the following recommended spill prevention procedures are to be implemented once construction begins on the site. DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 14 Preliminary DRAFT June 9, 2023 • Material safety data sheets, a material inventory, and emergency contact information will be maintained at the on-site project trailer. • Equipment, materials and manufacturers' recommended methods for spill cleanup will be clearly posted and site personnel will be made aware of the procedures and the location of the information and cleanup supplies. • Spill kits, materials and equipment necessary for spill cleanup will be kept at the on- site project trailer. Equipment and materials will include, but is not limited to, brooms, dust pans, mops, rags, gloves, goggles, kitty litter or speed-dry, sand, sawdust, shovels, wheelbarrows, and plastic and metal trash containers specifically designed for cleanup purposes. • All spills will be cleaned up immediately after discovery. • The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with a hazardous substance. • Spills of toxic or hazardous material in excess of reportable quantities will be reported to the Town of Barnstable and the Massachusetts DEP. • An appropriately trained supervisor will be designated as the spill prevention and cleanup coordinator. This individual will become responsible for the various phases of prevention and cleanup. The name of responsible spill prevention and cleanup coordinator will be posted on the site. • All personnel will be instructed, during tailgate training sessions, regarding the correct procedures for spill prevention and control. Notices that state these practices will be posed in the office trailer, and the individual who manages day-to-day site operations will be responsible for seeing that these procedures are followed. 3.6 DEWATERING Dewatering is not anticipated. If necessary, settling areas shall be constructed first and utilized as dewatering basins. If this is not feasible, the contractor shall meet on site with the engineer to establish locations for dewatering, using one of the methods outlined below. 1. Drainage generated as a result of trench dewatering shall be discharged to existing drainage courses with proper erosion control measures subject to approval by the Town. Discharge directly to wetlands and onto pavement or private property shall not be allowed. 2. Dewatering of excavated areas (if necessary) will be accomplished by pumping to designated temporary dewatering basins and/or perforated pipe/filter fabric DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 15 Preliminary DRAFT June 9, 2023 dewatering devices (designed to travel with the excavation work). The perforated pipe/filter fabric dewatering devices will be oriented parallel to existing site contours, and will outlet away from waterways and water bodies. 3. In order to minimize the quantities and extent of dewatering, trench excavation, utility installation, backfilling, and stabilization will be conducted in segments. The length and duration of excavated trench segments will vary in accordance with field conditions, dewatering capacity, and the practical needs of the pipe installation operation. 4. Sediment/dewatering basins shall be constructed as required prior to excavation activities for utility installation in areas of high groundwater. These basins will act to settle suspended solids from pumped groundwater prior to the release of this water. Basin will be excavated where possible; additional storage volume will be provided by surrounding the basin with excavated soil and a berm of silt socks, haybales and/or filter fabric fencing. Additional basins will be constructed as necessary to meet the needs of any dewatering operation. 5. As an alternative to sediment basins in upland, gradually sloping areas, trench dewatering may be conducted by pumping released groundwater into a 100-foot long perforated pipe (wrapped in filter fabric). Pipe will be placed along (parallel to) elevational contours to minimize the rate of release from the pipe line. The open end of the pipe will be oriented away from waterways. The filter fabric wrapping will be cleaned or replaced as needed. 4.0 TIMING OF CONTROLS As indicated in the Sequence of Major Activities, siltation barriers, erosion control measures and crushed stone tracking pads will be installed prior to clearing, grubbing, and excavation activities.

The contractor (TBD) shall be responsible for the proper inspection and maintenance of all stormwater and erosion control facilities until the project construction is completed. The contractor shall clean all components of the stormwater management system at the completion of construction, immediately prior to turning over operation and maintenance responsibility to the project proponent. 2. Upon completion of construction, the operation and maintenance of all components of the stormwater management system will be the responsibility of the owner: TBD 3. The owner/contractor/facility manager shall file an inspection report with the design engineer and, if necessary, the Town of Barnstable following each site inspection as recommended in the O&M schedule. Copies of the inspection reports are to be made available to the EPA as required per the 2022 EPA Construction General Permit. The inspection report shall identify the date of inspection, name and contact number of responsible party, specific structures inspected, specific maintenance and/or repairs required and general observations. Any deficiencies noted in the inspection report DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 17 Preliminary DRAFT June 9, 2023 shall be corrected to the satisfaction of the above referenced agencies. 4. Disposal of accumulated sediment and hydrocarbons to be in accordance with applicable local, state and federal guidelines and regulations. 5. There shall be no illicit discharge of any waste or waste water into the stormwater management system. The maintenance of the facility shall be undertaken in such a manner as to prevent any discharge of waste or waste water into stormwater management system. Any waste products generated during maintenance shall be properly disposed of off-site. Erosion Control Facilities Erosion Control Barriers Inspect weekly and after every major storm event (>0.25 inches per 2022 CGP) during construction and for the first few months after construction to ensure proper stabilization and function, thereafter inspect at least twice per year during wet weather to ensure the trenches are draining properly and the surrounding area is clear of debris. Check for erosion, clogging and trash, and remove organic matter, weeds, trash and debris as necessary during construction, while dry and at least every five years after construction. Stabilized Construction Entrances The entrances and exits to and from the site shall be maintained in a condition which will prevent tracking or flowing of sediment onto public right-of-way. All sediment spilled, dropped, washed or tracked onto public right-of-way must be removed immediately. Stormwater Facilities Stormwater Basins At a minimum shall be inspected after every major storm event (>0.25 inches per 2022 CGP) for the first six (6) months, then in the spring and fall of every year, thereafter. Note how long water remains standing in basin after a storm; standing water within the basin >72 hours after storm events should be immediately addressed. Also, within the basin, check for signs of differential settlement, cracking, erosion, leakage in embankments, tree growth in embankments, condition of riprap, sediment accumulation and the health of the turf. Stormwater basins shall be mowed a minimum of twice per year. Grass clippings and accumulated organic matter should be removed from the basin to a non-sensitive area. DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 18 Preliminary DRAFT June 9, 2023 Repairs and reseeding should be done as required. Sediment and debris should be removed manually when stormwater basin is thoroughly dry, a minimum of once per year or when the sediment level reaches a depth of three inches (3”) in the basin or half an inch (1/2”) in the low flow drain. 6.2 RECORD KEEPING The contractor shall keep records of all inspections and maintenance performed on the stormwater BMP’s and the erosion and sedimentation control devices. Inspection forms are provided in Appendix A. Inspection reports should address, at a minimum: • Date of Inspection • Name of Inspector • Qualifications of Inspector • Areas and/or devices that were inspected • Observed conditions of items • Any maintenance or other activity that was performed • Corrective measures needed Records of the inspections shall be kept in the on-site office trailer and copies provided to the design engineer and the Town of Barnstable, if required. If inspection results dictate the need, modifications and/or additions should be made to the Stormwater Pollution Prevention Plan to provide a better functioning erosion and sedimentation control system. All modifications required to correct stormwater controls must be made within 7 days of discovery of the issue. When the corrective actions result in changes to any of the stormwater controls or procedures documented in the SWPPP, the SWPPP must be modified accordingly within 7 days of completing corrective action work. Other records that should be kept on site are listed below: • Dates of grading, construction activity, and stabilization • A copy of construction general permit • Inspection reports • A copy of the EPA notification of their receipt of the complete NOI/application. A log must also be kept to record any changes in the activities or their timing on the project, changes in personnel, changes in inspection and maintenance procedures, updates DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc. Page 19 Preliminary DRAFT June 9, 2023 to construction plans, and any other changes made to proposed design plans. Documentation of the training of staff must also be kept by the contractor including dates, number of attendees, subjects covered and length of training. The following personnel must be trained prior to the commencement of any earth- disturbing or pollutant generating activities: • Personnel who are responsible for the design, installation, maintenance, and/or repair of stormwater controls (including pollution prevention measures) • Personnel responsible for the application and storage of treatment chemicals • Personnel who are responsible for conducting inspections as required • Personnel who are responsible for taking corrective actions Remainder of Page Intentionally Left Blank DRAFT Stormwater Pollution Prevention Plan Wakeby Road Solar Project Atlantic Design Engineers, Inc.
