Sizing Criteria This SWPPP includes post-construction stormwater management practices, which will be designed to meet the applicable sizing criteria, as discussed in Part IV of GP-0-25- 001. The criteria include Water Quality Volume (WQv), Runoff Reduction Volume (RRv), Channel Protection Volume (Cpv), Overbank Flood (Qp), and Extreme Flood (Qf), and are defined as follows: • Water Quality Volume (WQv): New York has defined the WQv as the volume of runoff generated from the entire 90th percentile rain event. Essentially, a practice sized using the WQv will capture and treat 90% of all 24-hour rain events. The WQv is directly related to the amount of impervious cover constructed at a site. Pursuant to Section 4.2 of the Design Manual, the following equation can be used to determine the WQv: 𝑊𝑃𝑣=𝑃∗𝑃𝑣∗𝐴 12 where: P = 90% Rainfall Event Rv = 0.05 + 0.009 (I), where I is percent impervious cover A = site area in acres (contributing area) • Runoff Reduction Volume (“RRv”): Reduce the total WQv by application of runoff reduction techniques and standard stormwater management practices with RRv capacity. Pursuant to Section 4.2 of the Design Manual, the 𝑃𝑃𝑣𝑚𝑖𝑚 can be calculated using the following equation: 𝑃𝑃𝑣𝑚𝑖𝑚=𝑃∗𝑃̅𝑣∗𝐴𝑖𝑐∗𝑃 12 where: 𝑃𝑃𝑣𝑚𝑖𝑚= Minimum runoff reduction volume required from impervious area (ac- ft) 𝑃𝑣= = 0.05 + 0.009 (I), where I is 100% impervious Aic = Total area of new impervious cover S = Hydrologic Soil Group (HSG) Specific Reduction Factor (S) • Channel Protection Volume (“Cpv”): Provide 24-hour extended detention of the post-developed 1-year, 24-hour storm event remaining after runoff reduction. The Cpv requirement does not apply when: o Reduction of the entire Cpv is achieved by application of runoff reduction techniques or infiltration systems, or o The site discharges directly to tidal waters, or fifth order or larger streams. • Overbank Flood Control Criteria (“Qp”): Requires storage to attenuate the post- development 10-year, 24-hour peak discharge rate (Qp) to predevelopment rates. The Qp requirement does not apply when: o The site discharges directly to tidal waters or fifth order or larger streams, or o A downstream analysis reveals that overbank control is not required.

The Qf requirement does not apply when: o The site discharges directly to tidal waters or fifth order or larger streams, or o A downstream analysis reveals that overbank control is not required. These criteria are further discussed below in Section 3.0 of this SWPPP and are calculated in Appendix I. 1.2. Purpose This SWPPP fulfills the requirements of the New York State Department of Environmental Conservation (NYSDEC) State Pollutant Discharge Elimination System (SPDES) General Permit for Storm Water Discharges from Construction Activity (GP-0- 25-001) (Appendix A). This Stormwater Pollution Prevention Plan (SWPPP) has been prepared on behalf of NY Groton II (South Main Street), LLC. (Owner) to support the proposed construction activities (Work) at South Main Street , Groton, New York, 13073 (Site). The Site is identified on the Tompkins County Tax Map as ID 31-1-12.1. For detailed information regarding the design and planned construction activities, refer to the “Existing and Proposed Site Plans” (Construction Drawings) prepared by P.W. Grosser Consulting Engineer and Hydrogeologist, P.C. (Engineer) included as Appendix D. 1.3. Project Description NY Groton II (South Main Street), LLC is proposing to develop an approximately 4.0- megawatt of alternating current (MW AC) ground-mounted solar facility on a 58.73±- acre site which is located on the south side of South Main Street. The owners would lease 16.17± acres of the subject property to the applicant (i.e., NY Groton II [South Main Street], LLC). The area of disturbance for the proposed action would be approximately 21.02 acres which would include a portion of the northern adjacent parcel (Tax Map No . 26-1-25.22) to be used for the construction of the proposed gravel access road from South Main Street. The proposed action would situate the solar facility on the southern portion of the subject property. The proposed development would include solar modules with a maximum height of 15 feet, the installation of an eight (8)-foot-high deer fence around the proposed solar facility, two (2) concrete equipment pad to house electrical equipment (i.e., two [2] inverter and two [2] transformer), electric utility lines to connect the solar panels to the existing distribution power line along the northeast side of the Site as well as the planting of a vegetative screen consisting of approximately 21 Leyland Cypress trees along the eastern portion of the Site. The proposed action would also include the construction of a gravel access road from South Main Street . The project area would be approximately 21.02 acres and would result in the clearing of 5.63± acres of woodland/forested area. Additionally, approximately 11.82 acres of agricultural land and 3.57 acres of meadows would be converted to landscaped areas. It is noted that the project area would be seeded with a northeast solar pollinator mix upon clearing. Construction of the solar facility will take place in a singular phase. All improvements are to conform to state, county and local standards and specifications. STORMWATER POLLUTION PREVENTION PLAN PAGE 7 P.W. GROSSER CONSULTING, INC • P.W.

This program allows subscribed participants to share the benefits of clean energy production. According to the applicant, a mix of residential and commercial customers, specifically New York State Electric and Gas (NYSEG) customers, would be able to receive a share of the solar power generated by the proposed action as well as a discount off their electricity bills. 1.4. Site Description The 58.73-acre Site is undeveloped and consists of predominantly inactive agricultural land as well as forested areas. Review of the NYSDEC Environmental Resource Mapper indicates that the subject property contains a Stream regulated as 898-97 and classified as C (i.e., for fisheries and non-contact activities). Additionally, this Stream is identified on the U.S. Fish and Wildlife Services National Wetlands Inventory (NWI) Mapper as a 5.53-acre Riverine classified as R4SBC. The NWI Mapper also indicates a portion of a 0.35-acre Freshwater Forested/Shrub Wetland classified as PSS1F is located on the southwest portion of the subject property. The NYSDEC Environmental Resource Mapper indicates there are no state-regulated freshwater wetlands on-site. Overall, the surface water features contained on-site total approximately 0.56 acres (see Sheet C- 100 of Construction Drawings in Appendix D). The subject property is zoned within the Rural Agricultural District (RA) and is within the New York State-Designated Agricultural District (Tompkins County Agricultural District 1). Stormwater runoff generated within the project Site limits occurs primarily as sheet flow. Runoff generally flows to Stream 898-97 located in the central north portion of the Site and to wetlands in the southwest portion of the site. Slopes within the Site limits are approximately 10% on average. 1.5. Adjacent Properties The land uses adjacent to the Site include single-family residential and agricultural land uses, as well as forested areas. 1.6. Soils Soils within the Site limits are identified below in Table 1. STORMWATER POLLUTION PREVENTION PLAN PAGE 8 P.W. GROSSER CONSULTING, INC • P.W.

Project Permitting and Compliance 1.9.1. Municipal Separate Stormwater Sewer System Permit Based on the NYSDEC Stormwater Interactive Map, the Site does not lie within a Municipal Separate Stormwater Sewer System (MS4). 1.9.2. Office of Parks, Recreation and Historic Preservation Review In accordance with the GP-0-25-001, any construction activities that have the potential to affect historic and/or archaeological resources are not eligible for coverage under the general permit unless the screening and consultation process specified in the Letter of Resolution that was developed between the NYSDEC and the NYS Office of Parks, Recreation and Historic Preservation (OPRHP) has been completed and the required documentation demonstrating that potential impacts have been avoided or mitigated is o btained and maintained on-site. Review of the New York State Cultural Resource Information System (CRIS) indicates that the Site does not lie within an archaeological sensitive area and there are no registered historic resources within the vicinity of the Site. It is noted that Bergmann and Associates, Inc. submitted a project consultation with OPRHP and a No Impact determination was issued on October 26, 2022, which is included a s Appendix H. 1.9.3. Climate Change Resiliency Planning As climate change is expected to cause a range of impacts, including temperature, precipitation, sea level rise, and frequency of extreme storms NYS has adopted the Community Risk and Resiliency Act (CRRA).

Water Quality Volume Calculations In addition to section 3.o, per Appendix B, Table 2 which states that; “Traditional impervious areas associated with solar development (e.g. roads, building, transformers)” are required to provide post-construction stormwater practices. Therefore Post-construction stormwater practices will be provided adjacent to transformers to meet water quality volume and runoff reduction associated with these impervious areas. The solar farm site will increase the impervious area by 0.002 ac from the installation of tw0 concrete pads for the inverters/transformers. HydroCAD models have been included in Appendix G. For this Site, the 90% rainfall event is assumed to be 1.0 inch based on the NYSDEC 90th percentile contour line. Grass Filter strips are proposed adjacent to the inverter/transformer pads to provide the required water quality volume and runoff reduction for the associated impervious area.

Site-related pollutants include concrete, dust and other debris. Activities that could impact stormwater include earthwork, waste disposal, and vehicular traffic. Site-related pollutants can originate from the handling, sorting, temporary storage, transport and disposal of soil, stone, and debr is that will be generated from site activities. This section also serves to identify th e types of temporary and permanent erosion and sediment controls that will be used during site activities. All erosion and sediment controls will be installed and maintained in accordance with the latest edition of the NYS Standards and Specifications for Erosion and Sediment Control (NYS Standards and Specifications). Erosion and sediment controls specific to this project are provided in the Construction Drawings (Appendix D). 4.1. Identification and Control of Potential Stormwater Pollutants 4.1.1. Significant Material Inventory Pollutants that result from the redevelopment of the site that have the potential to be present in stormwater runoff are listed in Table 10.

Good Housekeeping Practices Good housekeeping and spill control practices will be followed during site activities to minimize stormwater contamination from concrete, petroleum products and waste materials. Good housekeeping and spill control practices include the following: • Materials and equipment necessary for spill cleanup shall be maintained onsite in the equipment and waste material storage area, covered and secured. Equipment will include, but is not limited to, brooms, dust pans, mops, rags, gloves, goggles, plastic trash containers and trash liners. • On-site vehicles shall be monitored for leaks and will receive regular preventive maintenance to reduce the possibility of leakage. • Petroleum products shall be stored in tightly sealed containers which are clearly labeled. • Spill kits shall be included with all fueling sources and maintenance activities. • Spills shall be cleaned up immediately upon discovery. Spills large enough to reach the surface waters will be reported to the National Response Center at 1-800-424-8802. • Dump trucks hauling material from the site shall be covered with a tarpaulin. • Paved streets adjacent to the site entrances shall be swept as needed to remove excess mud, dirt, or rock tracked from the site. • Ruts caused by equipment used for clearing and grubbing shall be regraded. 4.2. Temporary Erosion and Sediment Controls Temporary erosion and sediment control measures will be installed prior to initiation of soil disturbing activities. This section identifies the types of temporary erosion and sediment controls that will be used during site activities. Each of the practices listed below are located on Sheet C-201 of the Construction Drawings and detailed on Sheet C - 601 of the Construction Drawings (Appendix D). 4.2.1. Site Planning and Prevention Measures This project will implement the following site planning and prevention measures for effective temporary and final erosion control during construction: • The contractor and Owner will work together to properly plan and sequence construction events in an effort to minimize the time that soil and stockpiled materials are exposed. • Temporary stockpiles of soil will be located in upland areas where stockpiles are protected from significant runoff. Additional stormwater perimeter controls may be required at downgradient locations. • Restore the surface (i.e., achieve the design grade and establish the vegetative cover or gravel) as soon as possible. • The contractor and Owner will evaluate site conditions prior to site clearing to determine if existing vegetation can be preserved or transplanted to the extent practical.

Stabilized Construction Entrance An SCE will be installed at the proposed site ingress/egress along South Main Street at the location indicated on Sheet C-201 of the Construction Drawings (Appendix D) and will be maintained throughout construction. The SCE shall be constructed with a 6-inch minimum layer of stone as indicated on the detail provided on Sheet C-601 of the Construction Drawings (Appendix D). The length of the SCE should be a minimum of 50 feet. The exact locations and lengths of the SCEs shall be determined by the contractor and Owner’s on-site representative on a case-by-case basis. The stabilized entrance shall capture mud and debris from vehicles before entering public roads to minimize the tracking of sediments off the property and will assist in controlling dust on the site. The contractor will be responsible for placing additional stone on the SCE as site activities progresses as necessary to maintain effectiveness. The SCE would be constructed such that any stormwater runoff that exits the Site would flow through the SCE to allow for the SCE to assist in filtering out sediment from the stormwater runoff. Additional SCEs would be installed as necessary at the work site if additional entrances are required as part of the proposed Work. The SCE(s) are to remain in place for the duration of the Work and until final site stabilization. 4.2.3. Perimeter Sediment Controls Silt fencing with wire mesh backing will be used to reduce the potential migration of suspended sediments from work areas to downgradient off-site areas. Silt fence will be installed along the limits of disturbance as well as on the vulnerable side of soil stockpiles (where applicable) and extend approximately 20% around the perimeters. The locations of the silt fence are as shown on Sheet C -201 of the Construction Drawings (Appendix D) and will be positioned parallel to the existing contours to the extent practical. Silt fence may also be installed around construction material and equipment staging areas, and as otherwise needed to control potential off-site migration of suspended sediments in sheet flow. 4.2.4. Drop Inlet Protection The silt fence will remain until all construction activities are completed. Care will be taken to install drop inlet protection for any drainage structures (if applicable) along South Main Street to prevent sediment build-up. 4.2.5. Dust Control Dust (particulate matter) control measures shall be implemented throughout the duration of the construction activities. STORMWATER POLLUTION PREVENTION PLAN PAGE 17 P.W.

Water for dust suppression shall be applied such that runoff does not occur and excessive “water weight” is not added to the soil. • Cover trucks carrying loose material such as debris generated by site activities, excavated soil or fill and verify that the covers are properly sealed. The following dust control measures shall be implemented at soil stockpiles in non-driving areas: • Spray water from a domestic water supply on stockpiles with appropriate distribution equipment that shall be kept on-site throughout the duration of the site activities. Water for dust suppression shall be applied such that runoff does not occur and excessive “water weight” is not added to the soil . • Cover stockpiles with plastic sheeting and verify that the covers are properly weighed down. 4.2.6. Temporary Seeding Temporary seeding of select areas may be implemented to reduce the potential for erosion and sediment transport from disturbed areas, bare soil areas, or soil stockpile areas. This seeding will be applied to provide a temporary protective cover on disturbed areas when construction activities have temporarily ceased, such as when preparing for winter shutdown, or to provide cover when permanent seed growth is delayed due to mid-summer heat or drought. If bare soil is exposed for more than 14 days, temporary seeding or other controls will be utilized to the extent practicable and will be initiated by the end of the next workday. Note that seeding should be performed promptly after completing the grading activities to minimize the need for surface roughening. Areas to be seeded will be scarified as needed prior to seeding. Seed mix will be the Ernest Northeast Solar Pollinator 3’ Mix. Runoff control measures shall be installed, as needed, prior to seeding to reduce the potential for erosion of the newly seeded area. 4.2.7. Topsoiling If seeding specification follows the “Permanent Seeding” Section, topsoil is not required at the project site. 4.2.8. Mulching Mulching will be performed immediately following seeding per NYS Standards and Specifications and the Landscape Plans and Details shown on the Const ruction Drawings (Appendix D). Mulching provides immediate erosion control during the establishment of vegetation, moderation of seedbed conditions (e.g., temperature STORMWATER POLLUTION PREVENTION PLAN PAGE 18 P.W.

Air-dried hay or straw mulch, which will be free of undesirable and course materials, will be applied at a rate of approximately two (2) tons (i.e., 100-200 bales) pounds per acre. Small grain straw would be utilized. 4.2.9. Surface Roughening Surface roughening will aid in the establishment of vegetative cover from seed, reduce runoff velocity and increase infiltration, and trap sediment. Surface roughening includes creating horizontal grooves across a slope (i.e., perpendicular to the downslope direction) using a spike-tooth harrow, tilling equipment, disking attachments, or tracking the area with appropriate construction equipment. The type of surface roughening techniques will be determined in the field by the contractor and the Owner’s on-site representative. 4.3. Permanent Erosion and Sediment Controls 4.3.1. Permanent Seeding Permanent seeding and sodding shall be implemented per NYS Standards and Specifications and the Landscaping Plan shown on Sheet C-500 of the Construction Drawings (Appendix D). This seeding will be applied to provide a protective cover following achievement of final grades or during a long-term dormancy period (e.g., longer than one [1] year). Consistent with temporary seeding, permanent seeding should be done promptly after completing the final grading activities to minimize the need for surface roughening. Areas to be seeded will be scarified as needed prior to seeding. Runoff control measures will be installed, as needed, prior to seeding to reduce the potential for erosion of the newly seeded area. 4.3.2. Water Bars Water bars are proposed for permanent erosion and stormwater controls across graded areas every 125 feet. Water bars are to be installed per the Site’s design plans and per the Design Manual. Water bars are intermittent ridges constructed across a slope to limit the accumulation of erosive velocity of water by reducing energy at pre-designed intervals. 4.4. Maintenance of Erosion and Sediment Controls As indicated in Section 1.0, the contractor is responsible for all maintenance of erosion and sediment controls in accordance with this SWPPP. The following maintenance practices shall be used to maintain erosion and sediment controls: • Excess sediment buildup will be removed from silt fencing when it has reached one-third the height of the barrier/fence. Fabric will be replaced when bulges or tears develop; silt fencing will be reinstalled if the fabric is not securely attached to the wire mesh and fence posts, the fabric is not properly entrenched in the ground, or if the fence posts are not properly secured in the ground.

Sediment which is washed or tracked to public rights-of-way will be removed immediately . • Excess sediment buildup will be removed from drainage structures. • The site shall be maintained and remain free of refuse and debris. • All seeded areas will be fertilized, reseeded as necessary, and mulched to maintain a vigorous, dense vegetative cover. 4.5. Pollution Prevention As indicated in Section 1.0 and in addition to the good housekeeping practices discussed in Section 4.1.3, the contractor will implement measures to prevent spills from occurring and to properly respond to spill emergencies. 4.5.1. Spill Prevention Plan At a minimum, the Site will be equipped with at least one (1) spill kit consisting of sorbents, absorbent booms, and fire extinguishers. In the event of a spill or leakage, the contractor will be responsible for safely mitigating the source condition and removal/disposal of any impacted materials. The contractor will take the following precautions to minimize the potential for spills of fuel or lubricants during construction activities: • Place secondary containment measures around all fuel and lubricant storage tanks/units. • Perform refueling activities on level ground within designated vehicle/equipment maintenance and fueling areas, away from steep slopes and runoff conveyance features (e.g., ditches, storm sewers, catch basins, etc.). • Do not leave equipment unattended during refueling. • Smoking, snacking, eating, etc., only in areas designated for such activities, that are located away from the refueling area. • Engines will not be running when refilling fuel tanks. • Replacing fuel caps immediately after filling and before starting the engine. • Securing fuel pump dispensers when not in use to avoid accidental fuel release. • Perform inspections and tests of equipment and portable fuel tanks to check for leaks and evaluate the condition of hoses and connections. If leaks are observed, transfer the contents to an alternate tank/storage unit and replace the equipment/tank or repair the leak, as appropriate. • Maintain all equipment in accordance with the manufacturer’s specifications. • Operate all vehicles and equipment safely and park them a safe distance away from site hazards and sensitive resources.

Spill Response Plan All spills will be immediately reported by the contractor to federal, state, and local agencies as required, as well as the Owner and Owner’s representatives. Reporting requirements of spills to necessary agencies will be in accordance with applicable regulations, and would include the following: • Ceasing operation of the affected equipment. • Containing the spill: If the spilled material is floating on a water surface, spill-absorbent pads/booms will be placed across the path of the floating spill. If the spilled material sinks below the water surface, a dam, weir, or other containment method will be used to stop the flow of the spilled material. If the spill occurs on land, in a ditch, dam, or other, a containment unit will be constructed to stop the flow of the spilled material. Absorbent material will be applied as necessary. • Cleaning up the spill: Spills in water will be recovered using the most appropriate measure until the spilled material is recovered (and no sheens or other evidence of the spill are observed). Spills on land will be recovered using pumps, sorbent material, hand tools, and/or heavy equipment, as necessary, until the spilled material is recovered. • Containerizing spill materials: Spilled materials, impacted soils, sorbent pads, and other spill cleanup or containment materials will be containerized in NYS Department of Transportation-approved containers. The containers will be labeled with the waste type and date of accumulation in accordance with applicable regulations. Samples will be collected to characterize the spilled materials for disposal, as required. • Disposing of spill materials: Impacted materials and spill cleanup debris will be disposed of at a facility permitted to accept such materials. • Performing post-spill maintenance: Following cleanup of the spill, the contractor’s project manager will verify that all used spill cleanup material and equipment have been disposed, or decontaminated, as appropriate. If the equipment that caused the spill cannot be properly repaired, replacement equipment will be obtained. In the event of a spill and/or emergency, the contractor’s project manager will also complete the activities described below: • Immediately notify appropriate site personnel (i.e., Owner’s on -site representative). • Inform all site personnel of any potential hazards and required levels of personal protective equipment (PPE) to conduct the cleanup. • Record the following information pertaining to the spill: o Name of the person(s) who identified and reported the spill incident; o Date, time, and location; o Brief description and cause of the spill; o Estimated quantity and type of material spilled; o Extent and description of impacts to soil, sediment, and water from the spill; STORMWATER POLLUTION PREVENTION PLAN PAGE 21 P.W.

Owners or operators must follow Part I.E.9. to modify the eNOI. 19 Part II. Part II. Water Quality-Based Effluent Limitations A. Maintaining Water Quality NYSDEC expects that compliance with the requirements of this permit will control discharges necessary to meet applicable water quality standards. It shall be a violation of the ECL for any discharge to either cause or contribute to a violation of the following water quality standards as contained in Parts 700 through 705 of Title 6 of the Official Compilation of Codes, Rules and Regulations of the State of New York: 1. There must be no increase in turbidity that will cause a substantial visible contrast to natural conditions; and 2. There must be no increase in suspended, colloidal or settleable solids that will cause deposition or impair the waters for their best usages; and 3. There must be no residue from oil and floating substances, nor visible oil film, nor globules of grease. If there is evidence indicating that the stormwater discharges authorized by this permit are causing, have the reasonable potential to cause, or are contributing to a violation of the water quality standard, the owner or operator must take appropriate corrective action in accordance with Part IV.C.5. of this permit and document in accordance with Part IV.C.4. of this permit. To address the water quality standard violation the owner or operator must include and implement appropriate controls in the SWPPP to correct the problem or obtain an individual SPDES permit. If, despite compliance with the requirements of this permit, it is demonstrated that the stormwater discharges authorized by this permit are causing or contributing to a violation of water quality standards, or if NYSDEC determines that a modification of this permit is necessary to prevent a violation of water quality standards, the authorized discharges will no longer be eligible for coverage under this permit, and the owner or operator must obtain an individual SPDES permit prior to further discharges from the construction site. B. Effluent Limitations Applicable to Discharges from Construction Activities Discharges authorized by this permit must achieve, at a minimum, the effluent limitations in Part II.B.1.a., b., c., d., and e. These limitations represent the 20 Part II.B. degree of effluent reduction attainable by the application of best practicable technology currently available. 1. Erosion and Sediment Control Requirements -The owner or operator must select, design, install, implement, and maintain control measures to minimize the discharge of pollutants and prevent a violation of the water quality standards. The selection, design, installation, implementation, and maintenance of these control measures must meet the non-numeric effluent limitations in Part II.B.1.a., b., c., d., and e. and be in accordance with the New York State Standards and Specifications for Erosion and Sediment Control (BB), dated November 2016, using sound engineering judgment. Where control measures are not designed in conformance with the design criteria included in the technical standard, the owner or operator must include in SWPPP the reason(s) for the deviation, or alternative design, and provide information in the SWPPP demonstrating that the deviation or alternative design is equivalent to the technical standard. a. Erosion and Sediment Controls. At a minimum, erosion and sediment controls must be selected, designed, installed, implemented, and maintained to: i. Minimize soil erosion through application of runoff control and soil stabilization control measure to minimize pollutant discharges; and ii. Control stormwater discharges, including both peak flow rates and total stormwater volume, to minimize channel and streambank erosion and scour in the immediate vicinity of the discharge points; and iii. Minimize the amount of soil exposed during construction activity; and iv. Minimize the disturbance of steep slope; and v. Minimize sediment discharges from the site; and vi. Provide and maintain natural buffers around surface waters, direct stormwater to vegetated areas and maximize stormwater infiltration to reduce pollutant discharges, unless infeasible; and vii. Minimize soil compaction. Minimizing soil compaction is not required 21 Part II.B.1.a.vii. where the intended function of a specific area of the site dictates that it be compacted; and viii. Unless infeasible, preserve a sufficient amount of topsoil to complete soil restoration and establish a uniform, dense vegetative cover; and ix. Minimize dust. On areas of exposed soil, minimize dust through the appropriate application of water or other dust suppression techniques to control the generation of pollutants that could be discharged from the site. b. Soil Stabilization. In areas where soil disturbance activity has ceased, whether permanently or temporarily ceased, the application of soil stabilization measures must be initiated by the end of the next business day and completed within 14 calendar days from the date the current soil disturbance activity ceased. For construction sites that directly discharge to one of the 303(d) segments listed in Appendix D, or are located in one of the watersheds listed in Appendix C, or are authorized to disturb greater than five acres in accordance with Part I.E.5.a.viii., the application of soil stabilization measures must be initiated by the end of the next business day and completed within seven calendar days from the date the soil disturbance activity ceased. c. Dewatering. Discharges from dewatering activities, including discharges from dewatering of trenches and excavations, must be managed by appropriate control measures. d. Pollution Prevention Measures. Select, design, install, implement, and maintain effective pollution prevention measures to minimize the discharge of pollutants and prevent a violation of the water quality standards. At a minimum, such measures must be selected, designed, installed, implemented, and maintained to: i. Minimize the discharge of pollutants from equipment and vehicle washing, wheel wash water, and other wash waters. Soaps, detergents and solvents cannot be used; and ii. Minimize the exposure of building materials, building products, construction wastes, trash, landscape materials, fertilizers, pesticides, herbicides, detergents, sanitary waste, hazardous and toxic waste, and other materials present on the site to precipitation 22 Part II.B.1.d.ii. and to stormwater. Minimization of exposure is not required in cases where the exposure to precipitation and to stormwater will not result in a discharge of pollutants, or where exposure of a specific material or product poses little risk of stormwater contamination (such as final products and materials intended for outdoor use); and iii. Prevent the discharge of pollutants from spills and leaks and implement chemical spill and leak prevention and response procedures. e. Surface Outlets. When discharging from basins and impoundments, the surface outlets must be designed, constructed, and maintained in such a manner that sediment does not leave the basin or impoundment and that erosion at or below the outlet does not occur. C. Post-Construction Stormwater Management Practice (SMP) Requirements 1. The owner or operator of a construction activity that requires post- construction SMPs, in accordance with Part III.C., must select, design, install, implement, and maintain the SMPs to meet the performance criteria in the New York State Stormwater Management Design Manual, dated July 31, 2024 (DM), using sound engineering judgment. Where SMPs are not designed in conformance with the performance criteria in the DM, the owner or operator must include in the SWPPP the reason(s) for the deviation or alternative design and provide information which demonstrates that the deviation or alternative design is equivalent to the technical standard. 2. The owner or operator of a construction activity, that requires SMPs in accordance with Part III.C., must design the practices to meet the applicable sizing criteria in Part II.C.2.a., b., c., or d. a. Sizing Criteria for New Development i. Runoff Reduction Volume (RRv) and Water Quality Volume (WQv): 1. Reduce the total WQv by application of RR techniques and standard SMPs with RRv capacity. The total WQv must be calculated in accordance with the criteria in Section 4.2 of the DM; or 23 Part II.C.2.a.i.2. 2. Minimum RRv and Treatment of Remaining Total WQv: Construction activities that cannot meet the requirements in Part II.C.2.a.i.1. due to site limitations must direct runoff from all newly constructed impervious areas to a RR technique or standard SMP with RRv capacity unless infeasible. The specific site limitations that prevent the reduction of 100% of the WQv must be documented in the SWPPP. For each impervious area that is not directed to a RR technique or standard SMP with RRv capacity, the SWPPP must include documentation which demonstrates that all options were considered and for each option explains why it is considered infeasible. In no case shall the runoff reduction achieved from the newly constructed impervious areas be less than the Minimum RRv as calculated using the criteria in Section 4.4 of the DM. The remaining portion of the total WQv that cannot be reduced must be treated by application of standard SMPs. ii. Channel Protection Volume (CPv): Provide 24 hour extended detention of the post-developed 1-year, 24-hour storm event, remaining after runoff reduction. Where a CPv control orifice is provided, the minimum orifice size must be 3 inches, with acceptable external trash rack or orifice protection. The CPv requirement does not apply when: 1. Reduction of the entire CPv is achieved by application of runoff reduction techniques or infiltration systems; or 2. The 1-year post-development peak discharge is less than or equal to 2.0 cfs without detention or velocity controls; or 3. The site directly discharges into a fifth order or larger water body (stream, river, or lake), or tidal waters, where the increase in smaller flows will not impact the stream bank or channel integrity. However, the point of discharge must be adequately protected against scour and erosion by the increased peak discharge. 24 Part II.C.2.a.iii. iii. Overbank Flood Control Criteria (Qp): Requires storage to attenuate the post-development 10-year, 24-hour peak discharge rate (Qp) to predevelopment rates. The Qp requirement does not apply when: 1. the site directly discharges to tidal waters or fifth order or larger streams, or 2. A downstream analysis reveals that overbank control is not required. iv. Extreme Flood Control Criteria (Qf): Requires storage to attenuate the post-development 100-year, 24-hour peak discharge rate (Qf) to predevelopment rates. The Qf requirement does not apply when: 1. the site directly discharges to tidal waters or fifth order or larger streams, or 2. A downstream analysis reveals that overbank control is not required. b. Sizing Criteria for New Development in Enhanced Phosphorus Removal Watersheds i. Runoff Reduction Volume (RRv) and Water Quality Volume (WQv): 1. Reduce the WQv by application of RR techniques and standard SMPs with RRv capacity. The total WQv is the runoff volume from the 1-year, 24-hour design storm over the post-developed watershed and must be calculated in accordance with the criteria in Section 4.3 of the DM; or 2. Minimum RRv and Treatment of Remaining Total WQv: Construction activities that cannot meet the criteria in Part II.C.2.b.i.1. due to site limitations must direct runoff from all newly constructed impervious areas to a RR technique or standard SMP with RRv capacity unless infeasible. The specific site limitations that prevent the reduction of 100% of the WQv must be documented in the SWPPP. For each impervious area that is not directed to a RR technique or standard SMP with RRv capacity, the SWPPP must include 25 Part II.C.2.b.i.2. documentation which demonstrates that all options were considered and for each option explains why it is considered infeasible. In no case shall the runoff reduction achieved from the newly constructed impervious areas be less than the Minimum RRv as calculated using the criteria in Section 4.5 of the DM. The remaining portion of the total WQv that cannot be reduced must be treated by application of standard SMPs. ii. Channel Protection Volume (CPv): Provide 24 hour extended detention of the post-developed 1-year, 24-hour storm event, remaining after runoff reduction. Where a CPv control orifice is provided, the minimum orifice size must be 3 inches, with acceptable external trash rack or orifice protection. The CPv requirement does not apply when: 1. Reduction of the entire CPv is achieved by application of runoff reduction techniques or infiltration systems; or 2. The 1-year post-development peak discharge is less than or equal to 2.0 cfs; or 3. The site directly discharges to tidal waters, or a fifth order or larger water body (stream, river, or lake) where the increase in smaller flows will not impact the stream bank or channel integrity. However, the point of discharge must be adequately protected against scour and erosion by the increased peak discharge. iii. Overbank Flood Control Criteria (Qp): Requires storage to attenuate the post-development 10-year, 24-hour peak discharge rate (Qp) to predevelopment rates. The Qp requirement does not apply when: 1. the site directly discharges to tidal waters or fifth order or larger streams; or 2. A downstream analysis reveals that overbank control is not required. 26 Part II.C.2.b.iv. iv. Extreme Flood Control Criteria (Qf): Requires storage to attenuate the post-development 100-year, 24-hour peak discharge rate (Qf) to predevelopment rates. The Qf requirement does not apply when: 1. the site directly discharges to tidal waters or fifth order or larger streams; or 2. A downstream analysis reveals that overbank control is not required. c. Sizing Criteria for Redevelopment Activity i. Water Quality Volume (WQv): The WQv treatment objective for redevelopment activity must be addressed by one of the following options, as outlined in Section 9.2.1. Redevelopment activities located in an Enhanced Phosphorus Removal Watershed (see Part III.B.3. and Appendix C) must calculate the WQv in accordance with Section 4.3 of the DM. All other redevelopment activities must calculate the WQv in accordance with Section 4.2 of the DM. 1. Reduce the existing impervious cover by a minimum of 25% of the total disturbed, impervious area. The Soil Restoration criteria in Section 5.1.6 of the DM must be applied to all newly created pervious areas; or 2. Capture and treat 100% of the required WQv, for a minimum of 25% of the disturbed redevelopment impervious area, by implementation of standard SMPs or reduced by application of runoff reduction techniques; or 3. Capture and treat 100% of the required WQv, for a minimum of 75% of the disturbed redevelopment impervious area, by implementation of a volume-based alternative SMP, as defined in Section 9.4 of the DM; or 4. Capture and treat 100% of the required WQv, for a minimum of 75% of the disturbed redevelopment impervious area, by implementation of a flow-through alternative SMP sized to treat the peak rate of runoff from the WQv design storm; or 27 Part II.C.2.c.i.5. 5. Application of a combination of 1 through 4 above that provide a weighted average of at least two of the above methods. Application of this method must be in accordance with the criteria in Section 9.2.1(A)(V) of the DM; or 6. If there is an existing SMP located on the site that captures and treats runoff from the impervious area that is being disturbed, the WQv treatment option selected must, at a minimum, provide treatment equal to the treatment that was being provided by the existing practice(s) if that treatment is greater than the treatment required by options 1 through 5 above. ii. Channel Protection Volume (CPv) is not required if there is 0% change to hydrology that increases the discharge rate and volume from the project site. iii. Overbank Flood Control (Qp) is not required if there is 0% change to hydrology that increases the discharge rate from the project site. iv. Extreme Flood Control (Qf) is not required if there is 0% change to hydrology that increases the discharge rate from the project site. d.

Steep Slope – land area designated on the current United States Department of Agriculture (USDA) Soil Survey as Soil Slope Phase D, (provided the map unit name or description is inclusive of slopes greater than 25%), or Soil Slope Phase E or F, (regardless of the map unit name), or a combination of the three designations. Stormwater – that portion of precipitation that, once having fallen to the ground, is in excess of the evaporative or infiltrative capacity of soils, or the retentive capacity of surface features, which flows or will flow off the land by surface runoff to waters of the State. 61 Appendix A Streambank – the terrain alongside the bed of a creek or stream. The bank consists of the sides of the channel, between which the flow is confined. Stormwater Pollution Prevention Plan (SWPPP) – a project specific report, including construction drawings, that among other things: describes the construction activity(ies), identifies the potential sources of pollution at the construction site; describes and shows the stormwater controls that will be used to control the pollutants (i.e. erosion and sediment controls; for many projects, includes SMPs); and identifies procedures the owner or operator will implement to comply with the requirements of the permit. See Part III of the permit for a complete description of the information that must be included in the SWPPP. Surface Waters of the State – shall be construed to include lakes, bays, sounds, ponds, impounding reservoirs, springs, rivers, streams, creeks, estuaries, marshes, inlets, canals, the Atlantic ocean within the territorial seas of the state of New York and all other bodies of surface water, natural or artificial, inland or coastal, fresh or salt, public or private (except those private waters that do not combine or effect a junction with natural surface waters), which are wholly or partially within or bordering the state or within its jurisdiction. Waters of the state are further defined in 6 NYCRR Parts 800 to 941. Temporarily Ceased – an existing disturbed area will not be disturbed again within 14 calendar days of the previous soil disturbance. Temporary Stabilization – exposed soil has been covered with material(s) as set forth in the technical standard, New York Standards and Specifications for Erosion and Sediment Control, to prevent the exposed soil from eroding. The materials can include, but are not limited to, mulch, seed and mulch, and erosion control mats (e.g. jute twisted yarn, excelsior wood fiber mats). Total Maximum Daily Load (TMDL) – the sum of the allowable loads of a single pollutant from all contributing point and nonpoint sources. It is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL stipulates Waste Load Allocations (WLA) for point source discharges, Load Allocations (LA) for nonpoint sources, and a margin of safety (MOS). Traditional Land Use Control MS4 Operator – a city, town, or village with land use control authority that is authorized to discharge under New York State DEC’s SPDES General Permit For Stormwater Discharges from Municipal Separate Stormwater Sewer Systems (MS4s) or the City of New York’s Individual SPDES Permit for their Municipal Separate Storm Sewer Systems (NY-0287890). Trained Contractor – an employee from the contracting (construction) company, identified in Part III.A.7., that has received four (4) hours of NYSDEC endorsed training 62 Appendix A in proper erosion and sediment control principles from a Soil and Water Conservation District, or other NYSDEC endorsed entity. After receiving the initial training, the trained contractor shall receive four (4) hours of training every three (3) years. It can also mean an employee from the contracting (construction) company, identified in Part III.A.7., that meets the qualified inspector qualifications (e.g. licensed Professional Engineer, Certified Professional in Erosion and Sediment Control (CPESC), Registered Landscape Architect, New York State Erosion and Sediment Control Certificate Program holder, or someone working under the direct supervision of, and at the same company as, the licensed Professional Engineer or Registered Landscape Architect, provided they have received four (4) hours of NYSDEC endorsed training in proper erosion and sediment control principles from a Soil and Water Conservation District, or other NYSDEC endorsed entity). The trained contractor is responsible for the day-to-day implementation of the SWPPP. Tree Clearing – construction activities limited to felling and removal of trees. Tree clearing does not include hand felling and leaving the trees in place with no support from mechanized equipment, which is not considered construction activity requiring coverage under this permit. Water Quality Standard – such measures of purity or quality for any waters in relation to their reasonable and necessary use as promulgated in 6 NYCRR Part 700 et seq. 63 Appendix B APPENDIX B – Required SWPPP Components by Project Type Table 1 CONSTRUCTION ACTIVITIES THAT REQUIRE THE PREPARATION OF A SWPPP THAT ONLY INCLUDES EROSION AND SEDIMENT CONTROLS The following construction activities that involve soil disturbances of one (1) or more acres of land, but less than five (5) acres: • Single-family home not located in one of the watersheds listed in Appendix C and not directly discharging to one of the 303(d) segments listed in Appendix D • Single-family residential subdivisions with 25% or less impervious cover at total site build-out and not located in one of the watersheds listed in Appendix C and not directly discharging to one of the 303(d) segments listed in Appendix D • Construction of a barn or other agricultural building, silo, stock yard or pen. • Structural agricultural conservation practices as identified in Table II in the “Agricultural Best Management Practice Systems Catalogue” (dated June 2023) that include construction or reconstruction of impervious area or alter hydrology from pre- to post-development conditions.

NY Groton II (South Main Street), LLC is proposing to develop an approximately 4.0-megawatt of alternating current (MW AC) ground-mounted solar facility on a 58.73±-acre site which is located on the south side of South Main Street. The owners would lease 16.17± acres of the subject property to the applicant (i.e., NY Groton II [South Main Street], LLC). The area of disturbance for the proposed action would be approximately 21.02 acres which would include a portion of the northern adjacent parcel (Tax Map No. 26-1-25.22) to be used for the construction of the proposed gravel access road from South Main Street. The proposed action would situate the solar facility on the southern portion of the subject property. The proposed development would include solar modules with a maximum height of 15 feet, the installation of an eight (8)-foot-high deer fence around the proposed solar facility, two (2) concrete equipment pad to house electrical equipment (i.e., two [2] inverter and two [2] transformer), electric utility lines to connect the solar panels to the existing distribution power line along the northeast side of the Site as well as the planting of a vegetative screen consisting of approximately 21 Leyland Cypress trees along the east portion of the Site. The proposed action would also include the construction of a gravel access road from South Main Street. The project area would be approximately 21.02 acres and would result in the clearing of 5.63± acres of woodland/forested area. Additionally, approximately 11.82 acres of agricultural land and 3.57 acres of meadows would be converted to landscaped areas. It is noted that the project area would be seeded with a northeast solar pollinator mix upon clearing. Construction of the solar facility will take place in a singular phase. All improvements are to conform to state, county and local standards and specifications.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 5 scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and Custom Soil Resource Report 6 identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called Custom Soil Resource Report 11 noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can Custom Soil Resource Report 12 be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

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.

This report discusses the existing site conditions, the subsurface soils encountered during the investigation and provides preliminary recommendations for the design of the proposed development. PROPOSED DEVELOPMENT The 58.89 acre site primarily consists of forested and agricultural land, located to the south of South Main Street. The development is focused on the farm fields on the eastern and southern portion of the site. The site grading at the farmland portion of the site generally slopes down from west to east, roughly starting at elevation El. +1100’ and sloping down to El. +1030’. The woodland area to the north of fields contains a creek that is traversable by a single crossing. The proposed solar facility is planned to be approximately 18± acres in area. PWGC’s understanding of the proposed development and geotechnical investigation scope is based on the following documents that were provided: • Layout Technical Review by EV Solar, dated October 18, 2023. INVESTIGATION SCOPE The field investigation included a reconnaissance of the site, excavation of test pits, obtaining soil samples from the test pit excavations, classifying soil materials and identifying the presence of bedrock and/or groundwater. Test pit excavations, designated as TP-001S through TP-007S, were carried out on 11/16/23 using a New Holland E37 excavator. The pits were excavated to 10 feet below grade surface (ft bgs). Soil materials were classified using the Unified Soil Classification System (USCS) (ASTM D-2487). See Attachment A for the test pit location plan. Soil samples were collected from each test pit and are stored at PWGC’s office for future testing, if necessary. Test pits were backfilled using the excavated native soils. A test pit log was prepared for each test pit. The logs contain full descriptions of the soil materials and note the presence of boulders, cobbles, bedrock and groundwater. See Attachment B for the test pits logs and Attachment C for test pit photos. FINDINGS – SUBSURFACE CONDITIONS The subsurface conditions can be broadly divided into four (4) distinct layers. The predominant soils were typical of glacially deposited till soils.

The soil was comprised of dark brown topsoil. Stratum 2, Brown Silty Sand (SP-SM, SM): Stratum 2 was the predominant soil type encountered. The material consisted of brown, medium to fine grained sands or containing some to little amounts of silt and little to trace gravel, cobbles, and boulders (3 inches to 2 ft in diameter). Stratum 2 was generally found between 0.5 ft to 10 ft bgs. The soil was classified as SP-SM or SM in accordance with USCS. Stratum 3, Grey Clay (SC, CL, CH): Stratum 3 varied between greyish brown clayey sand to grey, medium to high plasticity clay. This stratum was found in three (3) test pits, TP-001S from 6 ft bgs to 7 ft bgs, TP- 006S from 6 ft bgs to 10 ft bgs and in TP-007S from 4 ft bgs to 10 ft bgs. The soil was classified as SC, CL or CH in accordance with USCS. Stratum 4, Apparent Bedrock: Excavation refusal was encountered at 7 ft bgs in TP-001S. A stepout excavation was conducted next to TP-001S, refusal was encountered at 8.5 ft bgs, confirming that refusal was likely encountered due to a bedrock layer. FINDINGS – GROUNDWATER Groundwater was not encountered during the field investigation. FINDINGS – BEDROCK Bedrock was encountered in TP-001S at 7 ft bgs. TP-001S was located at the northeast corner of the array area. Bedrock geology maps indicate that soil deposits are underlain by bedrock of shale, limestone or siltstone comprising the Genesee Formation from the Late Devonian age. DISCUSSION OF FINDINGS The findings from this investigation suggest that the site is generally suitable for the proposed solar facility. The below section relates the investigation findings to fatal flaws typical of solar facility developments: • Supporting the solar arrays on driven, H-pile foundations appear feasible. o Shallow bedrock was encountered in only one of the test pits, TP-001S. This indicates that shallow bedrock conditions may be limited to the northeast corner of the proposed array area. o The predominant soil formation was found to have very limited amounts of cobbles/boulders ranging between 3” to 2’ in diameter. Cobbles and boulders can cause shallow refusal during pile installation. o Shallow, medium to high plasticity clays (Stratum 3) were found most commonly at the western boundary of the proposed array area (TP-006S and TP-007S). Soil borings and test piles will be needed to evaluate foundation design conditions between areas with and without the shallow clay formation. • Groundwater was not encountered during the field investigation. • The gradual sloping topography in the open farmland appears suitable for solar facility development. • Soil infiltration rates with respect to handling stormwater may be fair to poor based on silty sands of Stratum 2 and clays of Stratum 3.

A full geotechnical investigation will be necessary to characterize the subsurface conditions of any site. The below section relates this investigation’s specific findings to PWGC’s recommendations for a full geotechnical investigation. • The proposed soil boring layout will delineate the extent of the shallow bedrock encountered at the northeast corner of the array area (near TP-001S). The next phases in the geotechnical investigation will determine which foundation system is suitable for the shallow rock conditions (piles, ballast etc) or if the array layout can be made to avoid this area. • Soil borings and laboratory testing will define the engineering properties of the silty sands (Stratum 2) and clays (Stratum 3) and evaluate proposed piles for each soil type. • Soil borings refusals, if encountered, will investigate the likelihood of pile refusal during test pile and production pile installation. This will inform pile recommendations in the final geotechnical report. • The geotechnical investigation scope will assume that stormwater BMP’s will not require infiltration testing.

Stormwater Management Practice (SMP) Groups Stormwater management has become an important function for municipalities to address the quality of local water resources and to adhere to state standards. Increasingly, stormwater management practices (SMPs) are constructed as part of new development or redevelopment projects as retrofits to existing infrastructure and/or as part of local watershed restoration plan efforts. While SMPs are proliferating, municipalities are charged with a certain level of implementation and oversight. Whether this is a new function for a municipality or an expansion of existing programs, it is important for these local programs to have some degree of guidance to successfully meet the challenge. One important area where guidance has been lacking is how to properly operate and maintain the wide range of SMPs that are constructed. This chapter was developed to address this need. It is widely understood that SMPs will not function properly to protect water resources without attention to operation and maintenance (O&M), and that O&M tasks and responsibilities must be identified and assumed by various stakeholders. The chapter is structured around a hierarchy concept where O&M responsibilities are addressed by SMP owners/property managers, municipal staff, landscape contractors and professionals with knowledge in stormwater management (Qualified Professional). The hierarchy approach, explained in more detail below in Section 1.2, strives for a cost-efficient way to ensure long-term performance of SMPs. The maintenance procedures described in this chapter are applied to ten separate SMP groups (Table 1.1). These same ten groups are used to separate maintenance inspection guidance, costs, and other guidance in the chapter. Table 1.1 Practices Discussed in this Chapter, by Group SMP Group Practices Included Rainwater Harvesting Rain Barrel Cistern Disconnection and Sheetflow Rooftop Disconnection Sheetflow to Filter Strip Sheetflow to Riparian Buffers Swales Vegetated Swale Wet Swale Tree Planting Tree Planting Bioretention Bioretention Cell Dry Swale Rain Garden Stormwater Planters Tree Pits Green Roofs Green Roofs Permeable Pavements Permeable Pavers Porous Asphalt/Concrete Ponds and Wetlands Wet Pond Design Options Stormwater Wetland Design Options Infiltration Infiltration Trench Infiltration Basin Dry Well Sand and Organic Filters Surface Sand Filters Underground Sand Filters Underground Organic Filters Maintenance Guidance 3 1.2. Maintenance Hierarchy SMPs require inspections and maintenance to identify small problems before they become more serious and expensive to repair. For example, removing a small amount of sediment from a filtering medium or permeable pavement surface is much less expensive than replacing a surface that has already become clogged. However, it can be cost prohibitive for most communities or SMP owners to hire highly trained staff or contractors to inspect these practices or to carry out the actual maintenance tasks. This can be especially true with the advent of “micro-scale” Green Infrastructure practices, which may be distributed across many individual public and private properties, and where the absolute number of SMPs within a municipality may exceed local government inspection and maintenance capabilities. Many SMP maintenance problems start out as fairly small, easily rectified issues as long as they are detected early enough through an inspection. For these issues, property owners or managers can likely take care of the issue in an expedient and cost-effective manner. However, at some point, property owners or managers will encounter an issue where diagnosing the problem and knowing the appropriate remedy will exceed their technical capabilities. At this point, an individual with training in SMP inspection, operation and maintenance, such as a municipal inspector or landscape contractor, may have to be called in for assistance. Similarly, some problems escalate to the point where a Qualified Professional (i.e. professional engineer or landscape architect) is needed to bring the SMP back to a good functioning condition. The Qualified Professional may need to bring in other experts to assess problems with the SMP. For instance, they may call in a horticulturalist to Figure 1.1 The SMP Maintenance Hierarchy Pyramid assess problems with the planting plan. Acknowledging this step-wise approach to SMP inspection and maintenance, the SMP Maintenance Hierarchy concept was developed. The concept uses a combination of skill levels (Figure 1.1) as explained in more detail below. Level 1: Property Owners and Managers, Interns, etc. This category includes property owners, property managers, or HOA representatives, for privately owned SMPs. For municipally owned SMPS, this could include municipal maintenance staff or interns, and volunteers. These individuals would typically have no or only very limited training in stormwater maintenance and inspection but can use available guidance to quickly identify and rectify common and simple issues with SMP performance. This level completes routine inspections and maintenance activities. For most SMPs, the majority of inspection and maintenance activities can be conducted at this skill level, thus Level 1 forms the base of the Maintenance Hierarchy pyramid. Many well-functioning SMPs can be adequately maintained for long periods of time using Level 1 capabilities. Although many issues can be addressed at Level 1, these inspectors and maintainers need a relief valve when the SMP problems become harder to diagnose and/or the remedies require a higher level of resources and expertise. Such issues are referred to in this chapter as “kick-outs to Level 2.” For instance, an SMP may have a minor amount of sediment that has accumulated at inlets or on the practice bottom. A Level 1 person may be able to take care of this with a flat shovel and wheel barrow. However, a Level 2 inspection would be triggered if the sediment is deep, widespread, keeps recurring, and/or requires more sophisticated equipment to remove. Level 2: Trained Municipal Staff This level of inspection and maintenance is conducted primarily by municipal employees or landscape contractors who have completed training on SMP, inspection, operation and maintenance. Level 2 inspections can take place in response to two circumstances: 1. As part of an ongoing, routine municipal inspection program whereby SMPs are visited on a rotating basis at a frequency established by the local program, or Maintenance Guidance 4 2. In response to a “kick-out” from a Level 1 inspector based on a specific problem or problems. Circumstance #2 obviously will require coordination and communication between the Level 1 and Level 2 inspectors, with documentation and background provided by the Level 1 inspector. This is an essential part of making the hierarchy approach successful. In the example above, the Level 2 inspector can better diagnose the sources of the sediment, whether the sediment is affecting performance of the SMP, and the specific tasks needed to remove the sediment and abate the source. As with kick-outs from Level 1 to Level 2, the same can exist from Level 2 to Level 3. It may be that the Level 2 inspector encounters a problem where a Qualified Professional is needed to re-design certain components of the SMP, and a qualified contractor is needed to undertake a more serious repair. This is when Level 3 is activated. Level 3: Qualified Professionals Qualified professionals include professional engineers and landscape architects, who can revisit design issues associated with chronic or serious problems. For repair and maintenance of the SMPs at this level, individuals with specific skills and certifications, such as a certified plumber who has experience working with rainwater harvesting practices or a horticulturalist with knowledge on proper plantings may need to be called in by the Qualified Professional. Level 3 inspection or maintenance is triggered in response to specific problems identified during a Level 2 inspection. Continuing with the example above, the Level 2 inspector identifies that the sediment is accumulating in the SMP because of the lack of pre-treatment or that the practice is not sized properly for its drainage area. The Level 2 inspector at this point should consult a Qualified Professional (Level 3) who can go back to the original or as-built plan and develop workable solutions. Table 1.2 further describes how maintenance and inspection activities differ among the three levels of the SMP Maintenance Hierarchy. Table 1.2 Maintenance/Inspection Hierarchy Levels Level 1: Owners and Untrained Staff Level 2: Trained Municipal Staff Level 3: Qualified Professionals Qualifications/ Training of Inspectors No special training, but person is provided educational materials On-the-job training and/or short workshops Define adequate training or provide examples Professional License such as a PE or RLA Frequency of Inspection At least annually Routine as determined by the local program OR as kick-out from Level 1 inspection Only as needed from Level 2 inspection Inspection Guidance Checklists are included for each practice group in Section 2 of this chapter and in Appendix A. Guidance for the inspection is included in Section 3, and checklists are included in Appendix B. Section 4 includes guidance for diagnosing typical problems. Typical Maintenance Activities Routine mowing. Trash removal. Plant care and upkeep. Mulching as needed. Removal of small amounts of sediment from pretreatment areas of the practice. Removal of larger amounts of sediment. Structural damage repair. Minor regrading and scarification of soil surface to restore permeability. Redesign an improperly functioning practice. Includes re grading of the contributing drainage area, replacing soil media and plantings (new planting plan), or modifying conveyance structures. Triggers for Inspection or Maintenance by this Level Regular inspection (no trigger) Level 1 Inspection Sheets (Section 2) describe triggers that warrant a Level 2 Inspection. Level 2 Inspection Guidance (Section 3) describes triggers that warrant a Level 3 Inspection. Maintenance Guidance 5 1.3. Using the Remainder of this Chapter This chapter provides guidance for maintaining SMPs, including inspection, maintenance activities, and maintenance planning. The chapter includes four sections as follows: Section 2 outlines Level 1 inspection and maintenance procedures in the form of visual checklists. This includes guidance for inspection of each of the 10 SMP groups/categories included in this chapter, as well as specific kick- outs for Level 2. Section 3 provides guidance for Level 2 inspections as to observed conditions, remedies, and triggers for Level 3. Section 4 is most relevant to Level 3 and includes diagnostic measures for specific problems, as well as guidance for performing repair activities. Section 5 provides an overview of planning for maintenance, including techniques for estimating maintenance costs and elements of a maintenance plan. Section 2. Level 1 Inspections 2.1. How to Use this Section Section 2 provides guidance for Level 1 inspections of 10 groups of stormwater management practices (SMPs). See Section 1 of this chapter for an explanation of Level 1 in the Maintenance Hierarchy. Section 2.2 provides general guidance for Level 1 inspections. Sections 2.3 through 2.12 provide detailed Level 1 inspection guidance and inspection forms for each of the 10 practice categories: o 2.3 Rainwater Harvesting o 2.4 Disconnection and Sheetflow o 2.5 Swales o 2.6 Tree Planting o 2.7 Bioretention o 2.8 Green Roofs o 2.9 Permeable Pavement o 2.10 Ponds and Wetlands o 2.11 Infiltration o 2.12 Sand and Organic Filters 2.2. General Guidance for Level 1 Inspections Regardless of which practice you are inspecting, some key procedures and equipment are necessary. Read through this guidance before going on an inspection, and use the specific guidance in Sections 2.3 through 2.12 for the particular practice type you are inspecting. The Level 1 Inspection can be completed with minimal previous training. Typical Level 1 inspectors may include a property owner or manager (for private SMPs) or perhaps an intern or maintenance or landscape crew members in the case of a publicly owned practice. Level 1 inspections are the most frequent inspections. They are designed to identify key maintenance issues before they become more serious and to help keep up with routine maintenance tasks. Maintenance Guidance 6 When to Conduct a Level 1 Inspection The Level 1 Inspection should be conducted at least annually for all practices and is often supplemented with additional visits after large storms, winter salting and sanding, or other seasonal changes. In addition, it is recommended that inspections take place more frequently during the first few years after installation of an SMP. Many issues can be identified and corrected during this early period so that they do not lead to larger problems in subsequent years. Plant establishment and health is one of these key issues. Once the SMP is stable and seems to be functioning properly, the inspections can become less frequent. What to Take into the Field The Level 1 Inspection is fairly simple, and it is assumed that very little measurement will be needed. However, the inspector should take pictures to document findings and should also keep a record of the inspections. The list of needs for the Level 1 Inspection includes the following: 1. Safety vest (if SMP is located in an area near traffic) 2. Notes or records from past inspections 3. Digital camera or phone 4. Clipboard and pencils (if using paper forms), or Tablet or smartphone if using digital forms 5. Bug spray (if needed) 6. Sun block (if needed) 7. Tape measure (optional, to measure pipe sizes and SMP dimensions) 8. Letter of permission to access property if the inspector is from an outside agency (e.g., summer intern working for the municipality) 9. Site Plan showing SMPs, Planting Plan (includes planting/seed mixes) and details 10. Engineers scale 11. Flagging/stakes and waterproof marker (to mark problem areas that need to be visited again) Checklist and Follow-Up Actions The Level 1 Inspection checklists included in Sections 2.3 through 2.12 describe follow-up actions for each observed condition (See Figure 2.2.1 for an example). A Level 1 Inspection Table is available for each component or key area of the particular SMP group. Use as follows: Check the box in the LEFT column if the problem is present at the site. Check the appropriate follow-up actions in the RIGHT column, or add your own as needed to fix the problem. DOCUMENT all your actions. Keep copies of the Level 1 inspection tables, plus notes, photos, or other documentation of corrective measures to fix problems. Record dates of actions and any follow-up inspections. This will be important for communicating with Level 2 inspectors and/or the local stormwater program. Activate a Level 2 Inspection (Section 3) as guided by the table (shown in blue cells): These blue cells identify conditions when a more detailed inspection will be needed to further diagnose problems. As the problem becomes more severe, it will be necessary to activate a Level 2 inspection. Consult the local stormwater program authority for the most appropriate Level 2 inspection option. Maintenance Guidance 7 RWH 3. Outlets Description: An above-ground rainwater harvesting tank usually has at least two outlets—one at the top of the tank where water overflows when the tank is full, and one near the bottom of the tank for delivering the stored water by gravity feed. Many filters also have an outlet pipe to divert the first flush of roof runoff away from the tank. Any overflow outlet that spills onto the ground should have sufficient erosion control (e.g., rock or stone pad) to prevent erosion of the ground. Instruction: Examine the outlet pipe(s) and the point at which it overflows onto the ground. Consult Table 2.3.3 below. Table 2.3.3 RWH Outlets Problem (Check if Present) Follow-Up Actions Slow flow from outlet caused by faulty or clogged valve If clogging seems to be the problem, ream out sediment from valve if this can be done from exterior. Other: Kick-Out to Level 2 Inspection: Valve needs to be replaced or cannot be cleaned out from outside of tank. Flow from outlet is backing up toward building foundation. Add flexible pipe to end of outlet pipe to divert flow further away and downhill from building. Erosion or drainage issues at outlet Add a gravel and/or stone pad to reduce the impact from the water flowing out of the outlet pipe during storms. Other: Kick-Out to Level 2 Inspection: Rills have formed, erosion or drainage problems are more severe or cannot be resolved, or there is discoloration or other unusual conditions around the outlet. 2.4. Disconnection and Sheetflow Components of Disconnection and Sheetflow The intent of disconnection and sheetflow is for runoff from small areas of impervious cover to spread out evenly and dissipate in a grassy or vegetated area. It is a low-technology practice intended to reduce runoff at its source. Key components to inspect for Disconnection and Sheetflow include the following: D&S 1. Drainage Area D&S 2. Level Spreader/Energy Dissipator D&S 3. Treatment Area Note: The category of Disconnection and Sheetflow includes: Figure 2.4.1 Key Areas for Level 1 Inspection of Disconnection and Sheetflow with filter strip shown. R. Winston, NCSU Rooftop Disconnection – Runoff from a small rooftop is directed to a relatively flat pervious area. Sheetflow to Filter Strip – Runoff from a small parking lot, sidewalk, or other small impervious surface is directed to a relatively flat, uniformly graded grassy area. Sheetflow to Riparian Buffers – Runoff from a small parking lot, sidewalk, or other small impervious surface is directed to a relatively flat, well-vegetated riparian area. Maintenance Guidance 11 Disconnection and Sheetflow Level 1 Inspection The Level 1 Inspection focuses on the Drainage Area (D&S 1), Level Spreader/Energy Dissipater (D&S 2), and Treatment Area (D&S 3). This inspection should be conducted twice per year, preferably in the spring and fall. If possible, inspect the practice during a storm in order to better see any active blockages, bypassing, or other problems. D&S 1. Drainage Area Description: The drainage area consists of rooftops and/or impervious surfaces such as parking lots, driveways, or sidewalks. Pervious areas such as lawns or forests may also be part of the drainage area. Instruction: Visually inspect any surfaces in the drainage area. Consult Table 2.4.1 below. Table 2.4.1 D&S Drainage Area Problem (Check if Present) Follow-Up Actions Changes in flow; more runoff; runoff bypassing the practice For rooftop areas, make sure downspouts are still disconnected and conveying water into the treatment area. Look for and remove any “dams” of sediment and grass clippings that prevent water from entering the treatment area as sheet flow. Other: Kick-Out to Level 2 Inspection: Changes to drainage area size or amount of runoff due to construction, tillage, etc. For parking lots in the drainage area—sediment, grass clippings, or other debris has accumulated at pavement edge. For small, isolated amounts of debris, sweep up by hand and dispose properly so that it will not be exposed to runoff. Other: Kick-Out to Level 2 Inspection: Sediment is widespread and cannot be removed by manual sweeping. For parking lots in the drainage area—dips or damage at pavement edge caused flow to concentrate. Kick-Out to Level 2 Inspection: This will likely require special expertise to diagnose and fix pavement edge. Maintenance Guidance 12 D&S 2. Level Spreader/Energy Dissipator Description: Some disconnection and sheetflow practices have a structure in place to dissipate any concentrated runoff and turn it into sheet flow. This may consist of a stone or gravel spreader a concrete or wood level spreader, or other level and stable surface. Instruction: Inspect the energy dissipator closely, during a rain event if possible. Consult the Table 2.4.2 below. Table 2.4.2 D&S Level Spreader/Energy Dissipator Problem (Check if Present) Follow-Up Actions Debris and/or sediment accumulated behind or around the level spreader. Remove debris and sediment by hand and ensure that the area behind the level spreader is relatively flat. Too much debris and sediment can cause runoff to bypass the level spreader structure. Other: Sinking, cracking, sloughing, or other structural problem makes the energy dissipator no longer level. For stone/gravel spreaders, add new material or rake out as needed to make it even. Other: Kick-Out to Level 2 Inspection: Structural issues that cannot be easily fixed by hand Maintenance Guidance 13
