The proposed sewer pumping station is part of a larger overall wastewater collection and conveyance system being designed for Phase 1 of the Town-wide wastewater program being implemented in accordance with the Town’s approved Comprehensive Wastewater Management Plan (CWMP). (Phase 1: Contracts 2 and 3 have been filed with the Yarmouth Conservation Commission as a separate Request for Determination of Applicability). This pumping station is part of Phase 1 Contract 3. Sewerage flow from the proposed South Shore Drive pumping station will be pumped via a force main up to a proposed gravity sewer in Seaview Avenue, from there sewerage will flow by gravity to a proposed gravity sewer in Route 28. Eventually, when Phase 1 is completed, flow will be pumping to the Water Resource Recovery Facility (WRRF) at 99 Buck Island Road, which is currently under design. The construction of the proposed sewer pumping station qualifies as a Limited Project in accordance with Section 10.53(3) (d) of the Wetlands Protection Regulations, which includes “The construction, reconstruction, operation and maintenance of underground and overhead public utilities, such as electrical distribution or transmission lines, or communication, sewer, water and natural gas lines”. Limited projects may be issued an Order of Conditions notwithstanding the provisions of 310 CMR 10.54 through 10.58 and 10.60. The following sections address the existing on-site wetland conditions, work proposed adjacent to wetland resource areas, proposed measures to mitigate any wetland resource area impacts, and compliance with the performance standards. 2.0 Existing Conditions The proposed South Shore Drive pumping station will be located on a Town-owned parcel (Map 25, Lot 265) between Pine Grove Road to the west and the Bluebird Parker Beach Lodge to the east. The site is also bounded by South Shore Drive to the south and Oak Grove Road to the north. To the south of South Shore Drive is Parker River Beach. The site is currently undeveloped and all forested. 2.1 Land Subject to Coastal Storm Flowage LSCSF is defined as “land subject to any inundation caused by coastal storms up to and including that caused by the 100-year storm, surge of record or storm of record, whichever is greater.” The FEMA Flood Insurance Rate Map identify the 100-year floodplain at elevation 11 feet NAVD 88 for the Town of Yarmouth, see Figure 2. Attachment A • Project Narrative Page 2 2.2 Estimated Habitat There is no state listed rare or endangered species within or adjacent to the project area according to the MassGIS Online Viewer. 3.0 Proposed Work within LSCSF This project consists of constructing a new sewerage pumping station and access drive from South Shore Drive on a vacant Town-owned parcel. The new pumping station will be submersible, with a below ground wet well (i.e., deep below ground structure) that will house submersible pumps and valving in a separate area of the wet well. Each area will be accessed by individual H-20 rated hatches (see Sheet C-4). The pumping station will include a precast concrete control building with concrete pads at the two doorways; total new impervious area on the site will be 2,578 square feet. All of the electrical and control equipment, including the natural gas standby generator will be housed in the control room in the precast building adjacent to the access driveway. There will be an additional, smaller room in the precast building to allow space for a small odor control system in the future. The control room will have a single door and the future odor control room will have a double door. There will also be a small meter vault to house the flow meter. This will be located in the access driveway and will be entered via a standard 30-inch diameter manhole cover. Fill material will be brought in to build up the land to elevation 13 (NAVD88) in order to allow the first floor elevation (FFE) of the control station building and critical infrastructure to be 3 feet above the 100-year flood elevation (see Sheet C-5). Gravel infiltration trenches will be placed around the wet well/valve vault, control building, and driveway at elevation 13.0 feet. These trenches will provide water quality treatment and recharge to groundwater. A bioretention area is proposed at the entrance of the access driveway at South Shore Drive. The bioretention area will provide water quality treatment, recharge to groundwater and minimal peak attenuation for the access driveway from El. 10 to El. 13 ft (see Attachment C: Stormwater Report for further discussion). Before work starts, compost logs will be installed at the limit of work to prevent the transport of sediment to downgradient wetlands and waterways during construction. The compost log barrier will be inspected weekly and after all storm events of 0.5 inch or greater and repaired as needed. The barrier will be left in place until the area is permanently stabilized. A stockpile of compost logs will be maintained on site for routine maintenance and emergency repairs. Upon completion of construction, disturbed soils outside of the pumping station structures will be final graded with material to match existing conditions and seeded. A row of junipers will be planted to help screen the new facility from South Shore Drive. Additional plantings are also proposed as a screen to the adjacent Bluebird Parker Beach Lodge. A planting plan is included as Sheet C-6. The proposed work will result in approximately 9.322 square feet of permanent alteration to LSCSF out of which 2,578 square feet will be converted to impervious material (precast building and paved access way) and 6,744 square feet will be seeded with a lawn area seed mixture and planted in accordance with the planting plan (see Sheet C-6). An additional 2,878 square feet of Attachment A • Project Narrative Page 3 temporary alteration to LSCSF will be restored to preconstruction grades and seeded with a lawn area seed mixture. 4.0 Stormwater Management Compliance with the Massachusetts Stormwater Standards (the Standards) is required per the MWPA [310 CMR 10.05(6) (k) through (q)] since work is proposed within LSCSF. The Standards consist of ten stormwater management standards (coastal projects exempt from the peak attenuation) to be addressed for new or redevelopment projects. Since the proposed project results in an increase of impervious area it is considered a new development. Please refer to Attachment C for discussion of proposed stormwater management design, drainage analysis, stormwater checklist, and stormwater operation and maintenance plan. 5.0 Climate Resiliency and Adaptation The Town of Yarmouth is a participant in the Commonwealth’s Municipal Vulnerability Preparedness (MVP) program, which is a community-driven process to define natural and climate-related hazards, identify existing and future vulnerabilities and strengths of infrastructure, environmental resources, and vulnerable populations, and develop, prioritize, and implement specific actions the Town can take to reduce risk and build resilience. The final Yarmouth MVP Report is dated June 2019 and identified coastal erosion and shoreline change, sea level rise, flooding, and extreme temperatures among the most significant climate hazards facing the Town and with infrastructure vulnerability as one of the Town’s top resiliency concerns. Yarmouth’s wastewater facilities, including the South Shore Drive pumping station, will be designed in accordance with TR-16: Guides for the Design of Wastewater Treatment Works (TR-16) which are design guidelines for wastewater treatment facilities in New England developed by the New England Interstate Water Pollution Control Commission (NEIWPCC). These guidelines indicate that all critical equipment associated with wastewater conveyance and treatment facilities should be constructed a minimum of three feet above the effective FEMA 100-year floodplain elevation. In compliance with TR-16, the finished floor elevation (FFE) of the new pumping station control building will be at elevation 14 which is 3 feet above the effective FEMA 100-yr floodplain elevation (11 feet NAVD88). The proposed FFE of 14 feet is also above the effective 500-yr flood elevation of 13.9 feet based on FEMA mapped 0.2% Annual Chance Stillwater elevation. Furthermore, the pumping station design is in compliance with Executive Order (EO) 11988 Floodplain Management and EO Establishing a Federal Flood Risk Management Standard and a Process for Further Soliciting and Considering Stakeholder Input. 6.0 Mitigation Measures The following precautions will be taken to prevent impacts to nearby coastal wetland resource areas. Attachment A • Project Narrative Page 4 Construction Period Controlling erosion and transport of sediment to the downstream wetland resource areas requires development of site-specific best management practices (BMPs), both structural controls as well as proper management of construction activities. Please refer to Sheets CD-1 for details on the erosion and sedimentation and control measures. ▪ Staked compost logs will be installed at the limit of work prior to commencement of construction to prevent the transport of sediment and debris to downgradient drainage ditch and to demarcate the limit of work. A stockpile of compost logs will be stored in an easily accessible location for routine maintenance and emergency repairs. The compost log barrier will be inspected weekly and after all storm events and repaired as needed. The barrier will be left in place until the area is permanently stabilized. ▪ Work will proceed as rapidly as possible. Limiting the exposure time of disturbed soils to wind and precipitation will minimize the soil erosion and subsequent sedimentation. Spill Control Measures ▪ An equipment storage and refueling area will be established in the project vicinity. All overnight storage of construction equipment and vehicles, refueling and light maintenance activities will occur in this area. A construction fence will be installed around the limit of this area to identify its limit. ▪ Spill containment equipment (e.g., oil absorbent pads, oil absorbent materials, containment booms, shovels, etc.) will be stored in the equipment storage and refueling area in an easily accessible manner for use in the clean-up of accidental releases of fuel, hydraulic fluid, or other hazardous materials. Should there be an accidental release the proper authorities will be notified in accordance with all applicable federal, state, and local laws. ▪ To minimize the possibility of hydraulic fluid leaks, all hydraulic lines on all construction equipment and vehicles will be inspected at the end of each workday. If any excessive wear or leakage is observed, the line will be repaired prior to further use. In addition, a supply of oil absorbent materials (i.e., pads, "speedy dry," and/or booms) will be maintained with the equipment at the work area for immediate deployment in the event of an accidental release of fuel, hydraulic fluid, oil, etc. ▪ Any oil, hydraulic fluid, or other hazardous materials will be stored in original containers; fuels will be stored in tightly sealed containers which are clearly marked; and all such materials will be stored under a roof or in a covered enclosure. Post Construction Measures ▪ If seeding occurs outside of the growing season, temporary stabilization measures (i.e., mulching or erosion control blankets) will be used to prevent erosion until the area can be seeded during the following growing season. ▪ All disturbed soils will be seeded with a lawn area seed mixture; and Attachment A • Project Narrative Page 5 ▪ The compost log barrier will not be removed until a vegetative cover dense enough to prevent erosion is established. 7.0 Compliance with Performance Standards 7.1 Compliance with 310 CMR 10.00 310 CMR 10.00 has no performance standards for work within the LSCSF. 7.2 Yarmouth Wetlands Protection Bylaw Standards The Yarmouth Wetland Protection Regulations has performance standards for activities within LSCSF that result in altering land within 300 feet of a major estuary (Section 2.10). The South Shore Drive Pumping Station Project is not within 300 feet of a major estuary and therefore the performance standards do not apply. 8.0 Summary The interests of MGL Chapt. 131 Section 40 and 310 CMR 10.00 and the Yarmouth Wetlands Protection Bylaw and Wetlands Regulations will not be impaired as a result of this project. Appropriate erosion and sedimentation control measures will be implemented throughout the course of construction to prevent the transport of sediment to nearby coastal resources. Disturbed soils will be stabilized upon completion of construction to prevent erosion and sedimentation in the long-term.

ATTACHMENT C STORMWATER MANAGEMENT REPORT Page 1 of 6 South Shore Drive Pumping Station Stormwater Management Report 1.0 Existing Conditions The Town of Yarmouth (Town) is proposing to construct a new sewer pumping station on South Shore Drive. This pumping station is part of a larger overall proposed wastewater collection and conveyance system being designed for Phase 1 of the Town-wide wastewater program being implemented in accordance with the Town’s approved Comprehensive Wastewater Management Plan (CWMP). The collection and conveyance system will convey wastewater to the proposed Water Resource Recovery Facility at 99 Buck Island Road. This pumping station is included in Contract 3 of Phase 1. The proposed South Shore Drive pumping station will be located on a Town-owned parcel (Map 25, Lot 265) between Pine Grove Road to the west and the Bluebird Parker Beach Lodge to the east. The site is also bounded by South Shore Drive to the south and Oak Grove Road to the north. To the south of South Shore Drive is Parker River Beach. The site is currently undeveloped and all forested. The entire site is located within the 100-year floodplain, with a 100-year flood elevation of 11.0 ft, regulated as Land Subject to Coastal Storm Flowage (LSCSF). The topography at the site is generally flat, gently sloping back towards the northeast corner of the site from El 10.0 to El. 7.0 ft. The total modeled area, 12,530 sf (0.29 ac), is the area within the limit of disturbance and has no existing impervious area. Figure 1 shows the existing conditions drainage area map. 2.0 Proposed Conditions Under proposed conditions the pumping station will consist of a small control building to house the electrical equipment including an emergency generator, and below-grade wet well/valve vault and meter vault with an access driveway to be constructed on the property. Fill material will be brought in to build up the land to elevation land13.0 ft in order to allow the first floor elevation (FFE) of the control station building and critical infrastructure to be 3 feet above the 100-year flood elevation. Gravel infiltration trenches will be placed around the wet well/valve vault, control building, and driveway at elevation 13.0 ft. These trenches will provide water quality treatment and recharge to groundwater. A bioretention area is proposed at the entrance of the access driveway at South Shore Drive. The bioretention area will provide water quality treatment, recharge to groundwater and minimal peak attenuation for the access driveway from El. 10 to El. 13 ft. Since this site is LSCSF, the project is exempt from the peak attenuation requirement in the Massachusetts Stormwater Handbook. Overflows from the bioretention area will be directed towards the northeast corner of the property. The embankment area for the elevated pumping station will be vegetated with loam and seed and plantings. Under proposed conditions, the total impervious area is 2,580 sf (0.06 ac), due to the addition of the pumping station, wet well, and access driveway. Since there is an increase in the impervious area, this project qualifies as a new development project under the Massachusetts Stormwater Handbook. Figure 2 shows the proposed conditions drainage area map. South Shore Drive Pumping Station Stormwater Management Report Page 2 of 6 3.0 Drainage Analysis CDM Smith performed drainage analyses for the South Shore Drive pumping station for existing and proposed conditions. The drainage analyses determined peak discharge rates during the 2-, 10-, 25-, 50-, and 100-year, 24-hour storm events using HydroCAD, version 10.2. This computer model simulates stormwater runoff flows through drainage areas and stormwater management facilities and is based on the Soil Conservation Service (SCS) Method. Following is a summary of the methodology and assumptions used to perform the drainage analyses.  Precipitation data for standard storms used in the models were taken from NOAA Atlas 14, Volume 10. The estimated precipitation depths during the 2-, 10-, 25-, 50-, and 100-year 24- hour storms are 3.35, 4.88, 5.83, 6.56, and 7.30 inches, respectively (see Appendix A).  The Natural Resources Conservation Service’s (NRCS) Web Soil Survey was consulted to determine the hydrologic soil groups (HSG) for the site. The NRCS has classified the site as “Carver coarse sand” and assigned HSG “A” to this soil. In December 2022, CDM Smith implemented a geotechnical program for the Phase 1 sewer design. On December 15, 2022, CDM Smith advanced one borings at the corner of Pine Grove Road and South Shore Drive. The soil in the boring was uniform, described as medium dense, fine to medium sand. Groundwater was encountered 10 ft below ground surface. A future boring is currently planned at the site of the proposed pumping station. Based on the boring at the corner of Pine Grove Road and South Shore Drive, a conservative infiltration rate of 2.41 in/hr has been assumed for the recharge calculations in the bioretention area. This value is based on Table 2.3.3 in Volume 3, Chapter 1 of Massachusetts Stormwater Handbook, where “loamy sand” has an infiltration rate of 2.41 inches/hour and is assigned to HSG “A” soils. The existing ground elevation at the boring is approximately 11.0 ft; therefore, existing groundwater is at approximately EL.1.0 ft. Appendix B provides soils information from Web Soil Survey and the geotechnical field exploration program. Upon completion of the soil boring at the pumping station site, infiltration rate and depth to groundwater will be reassessed.  The project site was modeled as one drainage area for existing conditions; this drainage area is based on the limit of disturbance for the pumping station. For proposed conditions, it was modeled as three drainage areas: the pumping station area tributary to the gravel infiltration trenches, the access driveway tributary to the bioretention area, and the embankment area for the pumping station. The drainage areas are shown on Figures 1 and 2. In comparing existing and proposed conditions the design point is Town-owned parcel.  Curve Numbers (CNs) for the different land uses on the site were selected based on HSG “A” soils. Land uses included woods, grass cover, gravel and paved/impervious areas. Weighted CNs were calculated in HydroCAD.  Times of concentration (Tc) were based on the Velocity Method in the NRCS National Engineering Handbook (May 2010). A minimum Tc of 6 minutes was used for all drainage areas. South Shore Drive Pumping Station Stormwater Management Report Page 3 of 6 HydroCAD was used to generate peak rates of runoff for existing and proposed conditions. For conservatism in the design, infiltration within the bioretention area and gravel trenches was not included in the HydroCAD modeling. This approach provides worst-case peak discharge rates if the proposed gravel trenches and bioretention area are not maintained and they become clogged and no longer provide recharge. Table 3-1 provides a summary of modeling results for existing and proposed conditions at the South Shore Drive design point. As this table shows, peak discharge rates for proposed conditions are greater than existing conditions for all storm events. Under existing conditions, the forested lot generates no runoff. With the change in land use under proposed conditions, there is an increase in peak discharge rates. As previously mentioned, because this site is LSCSF, the project is exempt from the peak attenuation requirement. The stormwater runoff from the embankment area and pumping station building area will sheet flow onto the parcel where it will naturally infiltrate. Similarly, stormwater overflows from the bioretention area will be directed into the parcel and not South Shore Drive. Thus, even though there is an increase in peak discharge rates, the stormwater will remain on the parcel and not flow onto South Shore Drive. The HydroCAD modeling input and output can be found in Appendix C. Table 3-1 South Shore Drive Pumping Station - Yarmouth, Massachusetts HydroCAD Modeling Results Design Point: Town-Owned Parcel Storm Event Existing Conditions Proposed Conditions Peak Discharge Rate (cfs) Peak Discharge Rate (cfs) 2-Year, 24-Hour 0.0 0.1 10-Year, 24-Hour 0.0 0.2 25-Year, 24-Hour 0.0 0.3 50-Year, 24-Hour 0.0 0.5 100-Year, 24-Hour 0.0 0.6 The site was also analyzed for compliance with the recharge volume (Rv) and water quality volume (WQv) requirements in the Massachusetts Stormwater Handbook. Since the soils at the location of the pumping station are located on HSG “A” soils, the recharge target depth factor of 0.60 inches was used. The total corresponding Rv is 84 cf. Even though the infiltration rate for the sandy soils has been conservatively assumed to be 2.41 in/hr for the purposes of the recharge calculations, it is likely greater than 2.41 in/hr, and therefore, the water quality volume is based on 1.0 inch times the total impervious area, with a total corresponding WQv of 139 cf. Storage for the Rv and WQv for the site is provided in the gravel infiltration trenches and bioretention area. The drawdown time of the water in the bioretention area was calculated using the total storage volume provided below the spillway and the total available bottom surface area of the bioretention area, excluding the sediment forebay area. The drawdown calculations indicate that stormwater will infiltrate within the required 72 hours, based on the infiltration rate of 2.41 in/hr. South Shore Drive Pumping Station Stormwater Management Report Page 4 of 6 Table 3-2 summarizes the impervious area, the calculated required recharge and water quality volumes, along with the total storage volume provided in the gravel infiltration trenches and bioretention area. As shown in this table, the gravel infiltration trenches and bioretention area provide sufficient storage volume to meet the total required recharge volume and water quality volume for the site. Appendix D provides the recharge volume, water quality volume, and drawdown calculations. Table 3-2 Summary of Overall Impervious Area, Rv and WQv South Shore Drive Pumping Station Stormwater Management Facility Impervious Area (sf) Recharge Volume (cf) Water Quality Volume (cf) Volume Provided (cf) Gravel Infiltration Trench 1,670 84 139 243 Bioretention Area 910 45 76 208 Total 2,580 129 215 451 For new development projects, stormwater management systems must be designed to remove 80 percent of the average annual load (post-construction conditions) of Total Suspended Solids (TSS). The gravel infiltration trenches around the pumping station, wet well/valve vault and flat section of the access driveway will provide 80 percent TSS removal. The pumping station and wet well/valve vault are considered clean surfaces and, since the access driveway will be occasionally used, the access driveway is a relatively clean surface; therefore, pretreatment is not provided. It is also noted that the stormwater from the gravel infiltration trenches will infiltrate into 3 ft of fill soils. For the bioretention area, which provides stormwater treatment for the access driveway from El. 10 to 13 ft, pretreatment will be provided to help preserve the longevity of the bioretention area and because stormwater from the bioretention area will infiltrate into native soils. Since the infiltration rate is anticipated to be greater than 2.41 in/hr, a pretreatment TSS removal rate of 44 percent is required. Per the Massachusetts Stormwater Handbook, a grass channel with a velocity of 1 fps during the 24-hour storm associated with the water quality event combined with a sediment forebay provides 50% TSS removal, which meets the required 44% TSS removal pretreatment. The bioretention area provides an overall TSS removal rate of 90 percent. The TSS worksheets and calculations are provided in Appendix E. 4.0 Compliance with Stormwater Standards Under the Massachusetts Stormwater Management Standards, the project is classified as a new development because the impervious area at the South Shore Drive Pumping Station will increase under developed conditions. Hence, the project is required to meet the applicable Stormwater Management Standards. The following summary below describes compliance with each of the stormwater standards. The Stormwater Checklist is provided at the end of this section. 4.1 Stormwater Standard No. 1 The proposed project fully meets the requirement of Stormwater Standard No. 1, as there are no new untreated discharges. Stormwater runoff from the pumping station site will receive treatment in the gravel infiltration trenches and in the bioretention area. South Shore Drive Pumping Station Stormwater Management Report Page 5 of 6 4.2 Stormwater Standard No. 2 This site is located in Land Subject to Coastal Storm Flowage and is exempt from meeting this standard. As shown on Table 3-1, peak discharge rates for proposed conditions are greater than those for existing conditions for all storm events. However, all stormwater runoff will remain on the Town- owned parcel and will not flow into South Shore Drive. 4.3 Stormwater Standard No. 3 Recharge to groundwater is fully met through the gravel infiltration trenches and bioretention area. Since the soils are HSG “A” soils, the target depth factor for recharge is 0.6 inches. The Static Method was used to demonstrate that proposed bioretention area will drain within 72 hours. 4.4 Stormwater Standard No. 4 This standard is fully met. Water quality volume calculation is based on one inch because it is anticipated the actual infiltration rate is greater than 2.41 in/hr. The gravel infiltration trenches around the pumping station, wet well/valve vault, and flat section of the entrance driveway will provide 80 percent TSS removal. The bioretention area will provide 90 percent TSS removal. Because of the anticipated high infiltration rate, 44 percent pretreatment is provided for the bioretention area. The TSS removal worksheets and calculations are provided in Appendix E. 4.5 Stormwater Standard No. 5 This standard is not applicable to this project. There are no LUHPPLs in the project area. 4.6 Stormwater Standard No. 6 This standard is met; the site is not located within a critical area. 4.7 Stormwater Standard No. 7 This standard is not applicable to this project; it is a new development project because there is an increase in impervious area. 4.8 Stormwater Standard No. 8 The project is subject to a NPDES General Construction Permit, which will be obtained by the Contractor as part of the Phase 1 East of Parkers River project. A copy of the Stormwater Pollution Prevention Plan (SWPPP) will be submitted by the Contractor prior to construction. 4.9 Stormwater Standard No. 9 An Operation and Maintenance Plan and Long-Term Pollution Prevention Plan are included with this submittal in Appendix F. 4.10 Stormwater Standard No. 10 The proposed project fully meets the requirement of Stormwater Standard No. 10 as there are no illicit discharges.

Standard 5: Land Uses With Higher Potential Pollutant Loads (LUHPPLs) The NPDES Multi-Sector General Permit covers the land use and the Stormwater Pollution Prevention Plan (SWPPP) has been included with the Stormwater Report. The NPDES Multi-Sector General Permit covers the land use and the SWPPP will be submitted prior to the discharge of stormwater to the post-construction stormwater BMPs. The NPDES Multi-Sector General Permit does not cover the land use. LUHPPLs are located at the site and industry specific source control and pollution prevention measures have been proposed to reduce or eliminate the exposure of LUHPPLs to rain, snow, snow melt and runoff, and been included in the long term Pollution Prevention Plan. All exposure has been eliminated. All exposure has not been eliminated and all BMPs selected are on MassDEP LUHPPL list. The LUHPPL has the potential to generate runoff with moderate to higher concentrations of oil and grease (e.g. all parking lots with >1000 vehicle trips per day) and the treatment train includes an oil grit separator, a filtering bioretention area, a sand filter or equivalent. Standard 6: Critical Areas The discharge is near or to a critical area and the treatment train includes only BMPs that MassDEP has approved for stormwater discharges to or near that particular class of critical area. Critical areas and BMPs are identified in the Stormwater Report.

Hydrologic Soil Group—Barnstable County, Massachusetts (South Shore Drive Pumping Station (PS5)) Natural Resources Conservation Service Web Soil Survey National Cooperative Soil Survey 1/18/2023 Page 2 of 4 Hydrologic Soil Group Map unit symbol Map unit name Rating Acres in AOI Percent of AOI 252A Carver coarse sand, 0 to 3 percent slopes A 2.5 100.0% Totals for Area of Interest 2.5 100.0% Description Hydrologic soil groups are based on estimates of runoff potential. 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.

Dept. of Environmental Protection Appendix F Operation and Maintenance Plan/ Long-Term Pollution Prevention Plan Page | 1 Appendix F - South Shore Drive PS O_And_M_Ltp Post-Construction Operation and Maintenance Plan Project: South Shore Drive Pumping Station Location: South Shore Drive, Yarmouth, MA Owner/Responsible Party: Town of Yarmouth Department of Public Works This document describes the operation and maintenance activities for the proposed stormwater management facilities associated with the South Shore Drive pumping station. Gravel Infiltration Trench Gravel infiltration trenches are located around the pumping station, wet/dry well, and driveway. Maintenance activities include the following: · Inspect gravel infiltration trenches for the accumulation of debris after the first several rainfall events (upon completion of construction), after all major storms, and on regularly scheduled dates every six months. Any debris found in the gravel infiltration trench should be promptly removed. The frequency of inspections should be evaluated and adjusted, if warranted by inspection results. · Inspect the gravel infiltration trenches within 3 days after a major storm to look for ponded water. If there is ponded water at the surface, the gravel surface is likely clogged. · To address surface clogging, remove and replace the first layer of stone aggregate and the filter fabric. If water is ponded inside the gravel infiltration trench, it may indicate that the bottom of the gravel infiltration trench has failed. · To rehabilitate a failed gravel infiltration trench, strip all accumulated sediment from the bottom of the gravel infiltration trench, and then scarify and till the bottom of the trench to induce infiltration. Replace all the stone aggregate and filter fabric in the gravel infiltration trench. Grassed Channel A grassed channel along the driveway conveys stormwater to the bioretention area. Maintenance activities include the following: · Annually check for and remove sediment from the grass channel. Use hand methods when removing the sediment to minimize disturbance to vegetation and underlying soils. · Remove accumulated trash and debris prior to mowing. · Mow the grass channel on an as-needed basis during the growing season so that the grass height does not exceed 6 inches. Set the mower blades to no lower than 3 to 4 inches above the ground. · Inspect semi-annually the first year, and at least once a year thereafter. Inspect the grass for growth and for signs of rilling and gullying. Repair any areas of erosion and revegetate. If grass growth is affected by winter road salt, re-establish the grass in the spring. Page | 2 Appendix F - South Shore Drive PS O_And_M_Ltp Sediment Forebay The sediment forebay is located in the bioretention area. Maintenance activities include the following: · Inspect the sediment forebay monthly for sediment depth and signs of rilling and gullying, with repair being performed as needed. · Clean out the sediment forebay at least two times per year and when sediment depth is 3 inches. · Repair any vegetation damaged after removing the sediment. Damaged vegetation should be replaced by either reseeding or resodding. When reseeding, hydroseeding should be accompanied with a tackifier, blanket, or similar practice to ensure that no scour occurs in the forebay, while the seeds germinate and develop roots. Bioretention Area There is a bioretention area located at the entrance to the pumping station driveway. Maintenance activities include the following: · During the six months immediately after construction, inspect the bioretention area following the first two precipitation events of at least 1.0 in to ensure the system is functioning properly. Thereafter, inspect the bioretention basin on an annual basis and after storm events greater than or equal to the 1-year, 24-hour Type III precipitation event (currently 2.8 in/24 hrs). · Annually, check to ensure the filter surface remains well draining after storm events. If filter bed is clogged, is draining poorly, or has standing water on the surface 48 hours after a precipitation event, remove top few inches of material, and till, or rake remaining material as needed. Upon failure, excavate the bioretention area, scarify bottom and sides, replace filter fabric and soil, replant, and mulch. On average, replacement or rehabilitation of the filtration media will occur every 8 years. · Remove silt/sediment from the bioretention area when the accumulation exceeds 1 inch. · Perform a minimum of one inspection during the growing season to ensure the health, density and diversity of the vegetation. Vegetation should cover more than 75 percent of the system. Remove and replace dead vegetation. In addition, look for erosion, scour and unwanted growth; any unwanted growth should be removed with minimum disruption to the remaining vegetation. · During the fall, prior to the first snowfall, remove all fallen leaves. · Inspect the bioretention area on a monthly basis to remove trash and debris. · Prune and weed the plantings periodically to control the growth of unwanted plants. To maintain the permeability of the system, the vegetation within the bioretention area must be maintained with lightweight equipment, such as a hand-held line trimmer. · Use zero-phosphorus fertilizers, if needed, to promote growth of the plantings. · Replace the underlying mulch on a yearly basis. · Do not use the bioretention area for stockpiling of plowed snow and ice, compost, or any other material.

The driveway will be periodically swept to remove trash and debris. 2. The gravel infiltration trenches and bioretention area will be periodically inspected to remove trash and debris. 3. No hazardous materials shall be stored outside at the site. 4. Salt and de-icing chemicals shall be used sparingly at the site. 5. Any spills that occur at the site shall be contained and cleaned up in a timely manner to prevent the spilled product from entering the gravel infiltration trenches and bioretention area. All personnel who provide regular maintenance at the South Shore Drive Pumping Station Site site shall be trained annually on the pollution prevention measures described above.
