SCOPE A. PURPOSE: JERRY SMITH LLC intends to implement the appropriate Stormwater Pollution Prevention Plan measures in accordance with the SPDES general permit governing stormwater discharges during construction, and in accordance with erosion control practices. This section provides a descriptive explanation of the means by which JERRY SMITH LLC will comply with the National Stormwater Pollution Prevention Program. B. NPDES GENERAL PERMITS FOR STORMWATER DISCHARGE FROM CONSTRUCTION SITES: Regulations promulgated by the New York State Department of Environmental Conservation (NYSDEC) regulate the discharge of storm water from construction activities on sites where one (1) or more acres of soil is disturbed. One of the ways to comply with these regulations for affected sites is to request coverage under the General Permit for Construction Activities. (Copy enclosed herewith) In order to be authorized to discharge under the General Permit, a Stormwater Pollution Prevention Plan(SWPPP) for the site must be prepared in accordance with all applicable requirements of this permit and followed during the construction activities. If the construction activity is not subject to the requirements of a regulated, traditional land use control MS4 a Notice of Intent (NOI) form must be completed and received by the New York State Department of Environmental Conservation at least 5-days prior to any earth-disturbing activities. If the construction activity is subject to the requirements of a regulated, traditional land use control MS4, then the owner/operator must have its SWPPP reviewed and accepted by the MS4 prior to submitting the NOI to the Department. The owner/operator shall have the "MS4 SWPPP Acceptance" form signed and then submit that form along with the NOI to the Department. C. RESPONSIBILITIES OF CONTRACTOR REGARDING THE GENERAL PERMIT: The CONTRACTOR shall manage the discharge of stormwater from the site in accordance with the SPDES General Permit for Construction Activities conditions and the following provisions of this section of the specifications. The CONTRACTOR shall be responsible for conducting the stormwater management practices in accordance with the permit. The CONTRACTOR shall be responsible for providing qualified inspectors to conduct the inspections required by the SWPPP. The CONTRACTOR shall be responsible for any enforcement action taken or imposed by federal, state, or local agencies, including the cost of fines, construction delays, and remedial actions resulting from the CONTRACTOR'S failure to comply with the permit provisions. It shall be the responsibility of the CONTRACTOR to make any changes to the SWPPP necessary when the CONTRACTOR or any of his subcontractors elects to use borrow or fill or material storage sites, either contiguous to or remote from the construction site, when such sites are used solely for this construction site. Such sites are considered to be part of the construction site covered by the permit and this SWPPP. Off-site borrow, fill, or material storage sites which are used for multiple construction projects are not subject to this requirement, unless specifically required by state or local jurisdictional entity regulations. The CONTRACTOR should consider this requirement in negotiating with earthwork subcontractors,since the choice of an off-site borrow,fill,or material storage site JULY impact their duty to implement, make changes to, and perform inspections required by the SWPPP for the site. D. NOTICE OF INTENT: The NOI Permittee petitions the New York State Department of Environmental Conservation for the stormwater discharges during construction at this site to be covered by the SPDES General Permit for Construction Activity for the State of New York. A Notice of Intent(NOI) (using the form required by the NYSDEC) to be covered under this permit is hereby filed. An Erosion and Sediment Control Plan has been prepared and is attached herewith. E. CONTRACTOR RESPONSIBILITIES: The SWPPP and associated Erosion and Sediment Control Plans represent the MINIMUM erosion and sediment control measures that will be required to protect the site during construction. JERRY SMITH LLC and the CONTRACTOR understand that additional erosion and sediment control measures will be necessary during construction. It will be the responsibility of the CONTRACTOR to implement additional erosion and sediment control measures as necessary to protect the site NOI Permittee: JERRY SMITH LLC JERRY SMITH BATTERY ENERGY STORAGE SYSTEM 1 during construction. JERRY SMITH LLC and the CONTRACTOR shall designate a Project Manager prior to commencing construction.

It is the owner/operators responsibility to keep the SWPPP current so that, at all times, it accurately documents the erosion and sediment control practices that are being used or will be used during construction,and all Stormwater Management Practices that will be constructed on-site, including preparing as- built drawings that document the final construction conditions I. INSPECTIONS AND RECORD KEEPING: Inspections are required at least weekly by a "Qualified Inspector". Sites that have a waiver to disturb greater than five(5)acres require two(2)inspections every seven (7) days with at least two (2) days between inspections. Inspections shall continue until the site complies with the "Final Stabilization" section of this document and a Notice of Termination (NOT) has been filed with the NYSDEC. Each inspection must be followed up by a report documenting the inspector's findings and request the required maintenance and/or repair for the erosion and sedimentation control measures. The inspector shall notify the Project Manager within one day of the inspection of any deficiencies. Within one day of this notification the Project Manager must commence with corrective measures. It is imperative that the Project Manager documents the Inspection and Maintenance of all erosion and sedimentation control measures as soon as possible after the inspection and/or maintenance is completed. These records are used to prove that the required inspection and maintenance were performed and shall be placed in the SWPPP Ledger.. In addition to inspection and maintenance reports,records should be kept of the Construction Activities that occur on the site. The Project Sponsor shall retain copies of the SWPPP,all reports and data for a minimum of five(5)years after the project is complete. The following list identifies the required Inspection and Maintenance documentation that must be maintained by the Project Manager under this SWPPP. • Form 4 Inspection Report for SWPPP • Form 5 Requested Changes to the SWPPP(Modification Report) • Form 6 Record of Stabilization and Construction Activities • Form 6A Record of Temporary Erosion and Sediment Control Practices • Form 7 Project Rainfall Log J. SWPPP MODIFICATIONS: The inspection report should also identify if any revisions to the SWPPP are warranted due to unexpected conditions. The SWPPP is meant to be a dynamic working guide that is to be kept current and amended whenever the design,construction, operation, or maintenance of the site changes in a way which significantly affects the potential for the discharge of pollutants or when the plan proves to be ineffective NOI Permittee: JERRY SMITH LLC JERRY SMITH BATTERY ENERGY STORAGE SYSTEM 3 in eliminating or significantly minimizing pollutant discharges.Any such changes to the SWPPP must be made in writing on the Modification Report Form (Form 5) within 7 days of the date such modification or amendment is made. The CONTRACTOR'S failure to monitor or report deficiencies to the NOI Permittee will result in the CONTRACTOR being liable for fines and construction delays resulting from any federal, state, or local agency enforcement action. K. FINAL STABILIZATION AND TERMINATION OF PERMIT COVERAGE: The site will be considered finally stabilized when all soil disturbing activities have been completed and a uniform perennial vegetative cover for the unpaved areas and areas not covered by permanent structures has been established or equivalent permanent stabilization measures have been established and the development area no longer discharges stormwater associated with construction activities and a Notice of Termination (NOT) form filed by the NOI Permittee with the New York State Department of Environmental Conservation. This filing terminates coverage under the General Permit and terminates the CONTRACTOR'S responsibility to implement the SWPPP. Requirements of the SWPPP,including periodic inspections,must be continued until the NOT is filed. H.SITE DESCRIPTION A. PROJECT NAME AND LOCATION The JERRY SMITH BATTERY ENERGY STORAGE SYSTEM PROJECT site is geographically situated at Latitude N 42' 35'35",Longitude W 76' 33' 50"in the TOWN OF LANSING, TOMPKINS COUNTY, NEW YORK. The site is located on the south side of JERRY SMITH ROAD. The project site is comprised of 56.87 +/- acres of land. The overall disturbance area is 1.76 +/- acres. The project is bounded on the north, south, east and west by PRIVATE FORESTED. Access to the project will be from JERRY SMITH ROAD. The entire parcel will remain privately owned and maintained. Approximately 0.64 +/- acres of impervious surfaces, including travel surfaces will be constructed. On-going reclamation during construction will consist of all activities listed in Section 1.11I.A.1 for temporary actions. Permanent reclamation activities for the laydown area and other compacted areas shall follow the NYSDEC Deep- Ripping and Decompaction JULY 2008 guidance.Final stabilization is defined as the completion of all soil disturbance activities with the phase area having perennial vegetative cover with a density of eighty (80) percent, or other equivalent stabilization measures such as permanent landscape mulches, rock rip-rap or washed/crushed stone. B. NOI PERMITTEE'S NAME AND ADDRESS JERRY SMITH LLC 101 SUMMER STREET, SECOND FLOOR BOSTON, MA 02110 C. PROJECT DESCRIPTION The project will involve the installation of a 5-MWac battery energy storage system on an approximately 57-acre site. The design will include a fenced battery storage development footprint of over 1 acre. The installation will also include associated infrastructure such as a concrete equipment pad, a chain link fence and improved site access via a new gravel access road. Soil disturbing activities will include: 1. Construction of stabilized construction access points 2. Clearing and grubbing 3. Installation of batteries 4. Construction of stormwater areas 5. Construction of utilities on site 6. Construction of landscaped areas NOI Permittee: JERRY SMITH LLC JERRY SMITH BATTERY ENERGY STORAGE SYSTEM 4 7. Final grading D. RUNOFF COEFFICIENT, SOILS,AND RAINFALL INFORMATION The site consists of hydrologic soil types (HSG) B and D. The predevelopment Curve Number (CN) for meadow areas was determined to be 58 for B, and 78 for D; and wooded areas were determined to be 60 and 79. Soil within the project area varies from silt loam to gravelly silt loam with areas of well draining soils and poor draining soils, as described by the Soil Conservation Service. The post development CN for all disturbed areas was modeled to be the same as predevelopment. A CN of 98 was used for all post- development impervious surface areas. E. NAME OF RECEIVING WATERS Drainage will be directed via an on-site vegetated filter strip or infiltration basin with emergency overflow swales directed to existing drainage ways,and eventually into the Otis Creek off site. F. INDIAN COUNTRY LANDS The site is not located on any known current or previously designated Indian Country lands. G. ENDANGERED OR THREATENED SPECIES A review of the New York State Department of Environmental Conservation's (NYSDEC) Environmental Resource Mapper (http://www.dec.ny.gov/imsmaps/ERM/viewer.htm) indicated no known State regulated rare plants, rare animals or significant natural communities on-site. A letter has been received from the NYSDEC New York Natural Heritage Program stating that the project is likely to have no impact on endangered or threatened species. This letter is included within Section 6 of the SWPPP. H. HISTORIC PLACES A review of the New York State Historic Preservation Office(OPRHP)Geographic Information System Mapper(http://www.oprhp.state.ny.us/nr/main.asp)indicated that the site is not located in an archeo sensitive area. I. CLIMATE CHANGE RESILIENCY PLANNING With the Community Risk and Resiliency Act(CRRA)being adopted in New York State,JERRY SMITH LLC has demonstrated consideration of several future risks due to the effects of climate change. Increasing Temperature:When developing the battery layout,JERRY SMITH LLC is only proposing to develop approximately 1.76+/-acres of land.The roadway and equipment pads include only 0.64+/-acres of impervious surfaces to reduce material heat absorption(Urban Heat Island Effect)to the maximum extent possible.The stormwater management area on site is a vegetated filter strip and infiltration basin which will prevent runoff from entering heat-vulnerable environments. Increasing Precipitation:The use of a vegetated filter strip and infiltration basin will allow infiltration on- site which will minimize the amount of runoff and water quality pollution from leaving the site JERRY SMITH LLC will provide the proper long-term operation/maintenance procedures to ensure conveyance systems will not be overwhelmed during large and more frequent storm events.In the event of drought, there will be no physical or ecological risks due to the vegetated filter strip not retaining water. Rising Sea Level:According to the FEMA Flood Insurance Rate Map(Map No.36109C0079D)the project area is located within Zone X(unshaded),which is considered to be outside of the 500-year floodplain,see NOI Permittee: JERRY SMITH LLC JERRY SMITH BATTERY ENERGY STORAGE SYSTEM 5 Section 6 if a map was available.As such,there will also be no increase in storm surge within the project limits. Shifting Ecology:As stated in part G of this section,there are known State regulated rare plants,rare animals or significant natural communities on-site,but will remain unaffected by the development.The predominant wildlife species that might occupy the project site include squirrels,birds,and deer.The development of this project site will promote sustainable development and should not have any impact on the local ecosystem. III.CONTROLS A. EROSION AND SEDIMENT CONTROLS The following section describes the anticipated Erosion and Sediment Controls required for use during construction of the proposed site. These controls represent the MINIMUM erosion and sediment control measures that will be required to protect the site during construction. Additional erosion and sediment control measures will be necessary during construction. It will be the responsibility of the NOI permittee to authorize the CONTRACTOR to implement all additional erosion and sediment control measures necessary to protect the site during construction. 1. Stabilization practices include(but not limited to): a) Land clearing activities shall be done only in areas where earthwork will be performed and shall progress as earthwork is needed b) Frequent watering of excavation and fill areas to minimize wind erosion during construction. c) Use of stabilization fabric for all slopes having a slope of IV:3H or greater. d) Seeding and planting of all unpaved areas • Temporary seedings should be made within 24 hours of construction or disturbance. If not,the soil must be scarified prior to seeding. • Broadcasting or hydroseeding JULY be used as seeding methods. • Seeding mixtures should be as follows a) Ryegrass(annual or perennial)applied at 30 lbs.per acre(0.7 lbs./1000 sq. ft.) b) Certified "Aroostook" winter rye (cereal rye) applied at 100 lbs. per acre (2.5 lbs./1000 sq.ft.) *Winter rye shall be used if seeding in October/November. e) Topsoiling • Scarify all compact, slowly permeable,medium and fine textured subsoil areas. Scarify at approximately right angles to the slope direction in soil areas that are steeper than 5 percent. • Remove refuse,woody plant parts,stones over 3 inches in diameter,and other liter. • Topsoil material shall have at least 2 percent by weight of fine textured stable organic material,and no greater than 6 percent. • Topsoil shall have no less than 20 percent fine textured material (passing the No. 200 sieve)and not more than 15 percent clay. • Topsoil shall not be placed when it is partly frozen, muddy, or on frozen slopes or over ice,snow,or standing water. f) Mulching • For grass / legume establishment apply straw mulch applied at 2 ton/acre (90 lbs./1000 sq. ft.) and anchor with wood fiber mulch (hydromulch) at 500-750 lbs./acre (11 — 17 lbs./1000 sq.ft.) g) Protecting Vegetation During Construction • Limit soil placement over existing tree and shrub roots to a maximum of 3 inches. • Use retaining walls and terraces to protect roots of trees and shrubs when grades are lowered. Lowered grades should start no closer than the dripline of the tree. • Avoid trenching within the dripline of the tree. NOI Permittee: JERRY SMITH LLC JERRY SMITH BATTERY ENERGY STORAGE SYSTEM 6 • Construction limits should be identified and clearly marked to exclude equipment. 2. Structural practices include(but not limited to): a) Perimeter protection using silt fences b) Sediment basin(s) c) Stabilized construction exit points • Aggregate size shall be 2 inch stone or reclaimed/recycled concrete equivalent • Thickness shall be not less than 6 inches • Width to be the full width of the access point,but not less than 12 ft • Length shall be as required,but not less than 50 ft. • Filter cloth shall be applied over the entire area to be covered with aggregate • The entrance shall be maintained in a condition which will prevent tracking of sediment onto public rights-of-way or streets. When necessary,wheels must be cleaned to remove sediment prior to entrance onto public rights-of-way. d) Stormwater detention ponds(which DULY also serve as a temporary sediment basin) e) Stone Check Dam • Use graded stone 2 to 15 inches in size • Sediment accumulated behind the check dam shall be removed as needed to allow drainage through the check dam and prevent large flows from carrying sediment over the dam. 3. Sequence of Major Activities The CONTRACTOR will be responsible for implementing erosion and sediment control measures outlined in the SWPPP and any additional erosion and sediment control measures required to stabilize the site. The CONTRACTOR JULY designate these tasks to certain subcontractors as appropriate, but the ultimate responsibility for implementing these controls and ensuring their proper functioning remains with the CONTRACTOR. The order of activities will be as follows (refer to Stormwater Pollution Prevention Plan Sheet contained in this SWPPP for additional details): a) Construct temporary construction exits at locations shown on the SWPPP plan sheet. b) Install perimeter silt fences. C> Begin clearing and grubbing operations. Clearing and grubbing shall be done only in areas where earthwork will be performed and only in areas where building is planned to commence within 7 days after clearing and grubbing. d) Frequent watering of the excavation and fill areas shall be done to minimize wind erosion. e) Commence site grading and battery construction. f) Disturbed areas of the site where construction activity has ceased for more than 7 days should be temporarily seeded and watered. g) Finalize access road subgrade preparation. h) Install base material as required for pavement. i) Carry out final grading and seeding and planting,including stormwater management areas. j) Remove silt fencing only after all paving is complete and exposed surfaces are stabilized. k) Remove temporary construction exits only prior to pavement construction in these areas (These areas are to be paved last). NOI Permittee: JERRY SMITH LLC JERRY SMITH BATTERY ENERGY STORAGE SYSTEM 7 4. Stormwater Management The proposed stormwater management system was designed by The Environmental Design Partnership, Clifton Park,NY. The following paragraphs summarize the stormwater management measures to be incorporated on the site to control pollutants in stormwater discharges after construction is completed.

SPILL PREVENTION CONTROL AND COUNTERMEASURES(SPCC)PLAN A. MATERIALS COVERED The following materials or substances with known hazardous properties are expected to be present onsite during construction: Concrete Cleaning solvents Detergents Petroleum based products Paints Pesticides Paint solvents Acids Fertilizers Concrete additives Soil stabilization additives B. MATERIAL MANAGEMENT PRACTICES The following are the material management practices that will be used to reduce the risk of spills or other accidental exposure of materials and substances to stormwater runoff. 1. Good Housekeeping The following good housekeeping practices will be followed onsite during the construction proj ect. a) An effort will be made to store only enough product required to do the job. b) All materials stored onsite will be stored in a neat, orderly manner and, if possible, under a roof or other enclosure. c) Products will be kept in their original containers with the original manufacturer's label in legible condition. d) Substances will not be mixed with one another unless recommended by the manufacturer. e) Whenever possible,all of a product will be used up before disposing of the container. f) Manufacturer's recommendations for proper use and disposal will be followed. g) The job site superintendent will be responsible for daily inspections to ensure proper use and disposal of materials. 2. Hazardous Products These practices will be used to reduce the risks associated with hazardous materials. a) Products will be kept in original containers with the original labels in legible condition. b) Original labels and material safety data sheets (MSDS's) will be procured and used for each material. c) If surplus product must be disposed of, manufacturer's or local/state/federal recommended methods for proper disposal will be followed. d) A spill control and containment kit(containing, for example, absorbent such as kitty litter or sawdust,acid neutralizing powder,brooms,dust pans,mops,rags,gloves,goggles,plastic and metal trash containers,etc.)will be provided at the storage site. NOI Permittee: JERRY SMITH LLC JERRY SMITH BATTERY ENERGY STORAGE SYSTEM 16 e) All of the product in a container will be used before the container is disposed of. All such containers will be triple-rinsed with water prior to disposal. The rinse water used in these containers will be disposed of in a manner in compliance with state and federal regulations and will not be allowed to mix with stormwater discharges. 3. Product Specific Practices The following product specific practices will be followed on the job site. a) Petroleum Products All onsite vehicles will be monitored for leaks and receive regular preventative maintenance to reduce the chance of leakage. Petroleum products will be stored in tightly sealed containers which are clearly labeled. Any petroleum storage tanks used onsite will have a dike or berm containment structure constructed around it to contain any spills that JULY occur. Any asphalt substances used onsite will be applied according to the manufacturer's recommendations. b) Fertilizers Fertilizers will be applied only in the minimum amounts recommended by the manufacturer. Once applied, fertilizer will be worked in the soil to limit exposure to stormwater. Storage will be in a covered shed. The contents of any partially used bags of fertilizer will be transferred to a sealable plastic bin to avoid spills. c) Paints,Paint Solvents,and Cleaning Solvents All containers will be tightly sealed and stored when not in use. Excess paint and solvents will not be discharged to the storm sewer system but will be properly disposed of according to manufacturer's instructions or state and federal regulations. d) Concrete Trucks Concrete trucks will be allowed to wash out or discharge surplus concrete or drum wash water on the site,but only in either(1)specifically designated diked areas which have been prepared to prevent contact between the concrete and/or washout and stormwater which will be discharged from the site or(2) in locations where waste concrete can be poured into forms to make riprap or other useful concrete products. The hardened residue from the concrete washout diked areas will be disposed of in the same manner as other non-hazardous construction waste materials or JULY be broken up and used on site as deemed appropriate by the CONTRACTOR. The job site superintendent will be responsible for seeing that these procedures are followed. 4. Spill Prevention Practices In addition to the good housekeeping and material management practices discussed in the previous sections of this plan,the following practices will be followed for spill prevention and cleanup. a) Manufacturer's recommended methods for spill cleanup will be clearly posted and site personnel will be trained regarding these procedures and the location of the information and cleanup supplies. b) Materials and equipment necessary for spill cleanup will be kept in the material storage area onsite in spill control and containment kit (containing, for example, absorbent such as kitty litter or sawdust, acid neutralizing powder, brooms, dust pans, mops, rags, gloves, goggles, plastic and metal trash containers,etc.). NOI Permittee: JERRY SMITH LLC JERRY SMITH BATTERY ENERGY STORAGE SYSTEM 17 c) All spills will be cleaned up immediately after discovery. d) The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with the hazardous substances. e) Spills of toxic or hazardous materials will be reported to the appropriate federal, state, and/or local government agency, regardless of the size of the spill. Spills of amounts that exceed Reportable Quantities of certain substances specifically mentioned in federal regulations (40 CFR 302 list and oil) will be immediately reported to the EPA National Response Center, telephone 1-800-424-8802. Reportable Quantities of some substances which JULY be used at the job site are as follows: oil-appearance of a film or sheen on water pesticides-usually 1 lb. acids-5000 lb. solvents,flammable- 100 lb. f) The SPCC plan will be adjusted to include measures to prevent this type of spill from recurring and how to clean up the spill if there is another one.A description of the spill,what caused it, and the cleanup measures will also be included. If the spill exceeds a Reportable Quantity,all federal regulations regarding reports of the incident will be complied with. g) The job site superintendent will be the spill prevention and cleanup coordinator. He will designate the individuals who will receive spill prevention and cleanup training. These individuals will each become responsible for a particular phase of prevention and cleanup. The names of these personnel will be posted in the material storage area and in the office trailer onsite. VIII. CONTROL OF ALLOWABLE NON-STORMWATER DISCHARGES A. Certain types of discharges are allowable under the NYS Department of Environmental Conservation SPDES General Permit for Construction Activity, and it is the intent of this SWPPP to allow such discharges. These types of discharges will be allowed under the conditions that no pollutants will be allowed to come in contact with the water prior to or after its discharge. The control measures,which have been outlined previously in this SWPPP, will be strictly followed to ensure that no contamination of these non-stormwater discharges takes place. The following allowable non-stormwater discharges that JULY occur from the job site include: a) Discharges from fire fighting activities b) Fire hydrant flushings (see note below) c) Waters used to wash vehicles or control dust in order to minimize offsite sediment tracking d) Potable water sources such as waterline flushings (see note below), irrigation drainage from watering vegetation, routine exterior building washdown (without detergents present) (See Note below) e) Pavement washwaters where spills or leaks of hazardous materials have not occurred or detergents have not been used f) Springs and other uncontaminated groundwater, including dewatering ground water infiltration NOI Permittee: JERRY SMITH LLC JERRY SMITH BATTERY ENERGY STORAGE SYSTEM 18 g) Foundation or footing drains where no contamination with process materials such as solvents is present NOTE: CONTRACTOR shall neutralize any super-chlorinated water from water distribution pipes before releasing it into the environment.

Change of Owner or Operator When applicable: 1 . When property ownership changes, or when there is a change in operational control over the construction plans and specifications, the following process applies: a. The new owner or operator must meet the applicable prerequisites for submitting an eNOI in accordance with Part I.D.2.; and b. The new owner or operator must submit an eNOI in accordance with Part I.D.3.; and c. Permit coverage for the new owner or operator will be effective upon receipt of the LOA in accordance with Part I.D.3.b.; and d. The new owner or operator, upon receipt of their LOA, must provide their Permit ID to the original owner or operator; and e. If the original owner or operator will no longer be the owner or operator of the construction activity identified in the original owner's or operator's eNOI, the original owner or operator, upon receipt of the new owner's or operator's Permit ID in accordance with Part I.G.1 .d., must submit to NYSDEC a completed eNOT in accordance with Part V. that includes the name and Permit ID of the new owner or operator, or f.

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.13.1.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. Sizing Criteria for Combination of Redevelopment Activity and New Development Construction projects, that include both new development and redevelopment activity, must use SMPs that meet the sizing criteria calculated as an aggregate of the sizing criteria in Part II.C.2.a. or b. for the new development portion of the project and Part II.C.2.c. for the redevelopment activity portion of the project.

The proposed site development includes a BESS which consists of approximately 620 +/- linear feet (LF) of access road, equipment pads, stormwater management areas, and ten-foot-high perimeter fencing. The total area of proposed disturbance is approximately 1.76 +/- acres and 0.64 +/- acres of new impervious area will be associated with the project. A stormwater management system has been developed to provide pollutant removal, reduce channel erosion, prevent overbank flooding, and safely control extreme flood events in accordance with the NYS Stormwater Management Design Manual (Design Manual). The temporary erosion control measures and post-construction stormwater management systems for this project have been designed in accordance with those guidelines and subsequent discussions with the NYSDEC relative to their guidelines. Section 7.0 of this report addresses specific BESS panel application guidance. The proposed stormwater management system for the project will include the use of a vegetated filter strip and Infiltration area designed to convey runoff from the gravel access road and concrete equipment pads. Runoff from the impervious access road is directed into the vegetated filter strip or infiltration area prior to discharging offsite. This narrative presents a review of the design concepts and parameters of the stormwater management system for the proposed increased impervious areas, in accordance with NYSDEC application guidance, including the access roads and the equipment pads. The purpose of the stormwater management narrative is to ensure that changes in the surface runoff characteristics, as a result of the proposed construction, will not adversely impact adjacent or downstream properties. On-site stormwater management will be implemented in accordance with the Design Manual and NYSDEC application guidance to accommodate both additional stormwater runoff and to provide water quality treatment according to the green infrastructure standards. 2.0 Existing Conditions The site consists of mostly wooded and field areas with residential development on the northern side of the parcel. The topography of the land consists of drainage from a highpoint in the middle of the site out to all directions. The typical slopes within the area of the proposed development range from 1% to 10% Elevations at the site vary between 1086 and 1078 feet above sea level. 3 900 Route 146, Clifton Park, New York 12065 phone(518)371-7621 ENVIRONMENTAL DESIGN eco PARTNERSHIP, LLP. 2.1 Soil and Groundwater Conditions The USDA Natural Resources Conservation Service Soil Survey identifies the soils on the site, in the proposed development, consist of a variety of soil types from silt loam to a gravelly silt loam. These soils vary as Hydrologic Soil Groups (HSG) B and D. The results from the USDA Natural Resources Conservation Soil Survey (NRCS Soil Survey) are included in Section 6 of the SWPPP. 3.0 Predevelopment Stormwater Analysis The existing hydrologic conditions, in the area to be disturbed as a result of the proposed construction, were analyzed using Applied Microcomputer Systems' "HydroCAD" computer modeling program. The HydroCAD stormwater modeling program employs the United States Department of Agriculture's Soil Conservation Service (SCS) Technical Release 20 (TR-20) method for stormwater analysis. Using this modeling technique, the site is divided into "subcatchments" that represent specific areas contributing stormwater runoff to an existing, or proposed drainage feature. The subcatchments typically flow through "reaches" (i.e., swales, channels, or pipes) that convey the stormwater to storm basins or discharge areas. A hydrologic model of the existing site was prepared using the Hydrocad program. Three (3) large sub catchments were used to represent the existing drainage condition, see Figure 2. The existing parameters of topography, vegetation, slope and soil type are all incorporated into the predevelopment model. Table 1 presents a summary of the pre-development stormwater peak discharge for the 1 year, 10 year and 100-year design storm events at the respective Design Point. As will be discussed in subsequent sections, the post development stormwater discharge rate has been limited to the predevelopment discharge rate for the 1-year, 10-year, and 100-year storm events. Table 1: Pre-Development Runoff Rates Storm Event Total Discharge (cfs) 1-Year (1.97") 0.30 10-Year (3.36") 5.57 100-Year (5.73") 23.91 The pre-development Curve Numbers (CN) for the existing ground covers are listed in Table 2. 4 900 Route 146, Clifton Park, New York 12065 phone(518)371-7621 ENVIRONMENTAL DESIGN e4D PARTNERSHIP, LLP. Table 2: Pre-Development Ground Cover Pre-Development Ground Cover Description Curve Number Meadow, Non-grazed, HSG B 58 Meadow, Non-grazed, HSG D 78 Woods, Fair, HSG B 60 Woods, Fair, HSG D 79 Impervious 98 The weighted CN for the pre-development conditions for the site is approximately 65. The HydroCAD model results for the pre-development conditions are included within Attachment B. 4.0 Stormwater Management Planning and Practice Selection The site layout and stormwater design for this project was completed while taking into consideration the potential impacts on the existing site and downstream hydrology. Stormwater runoff from the existing site predominately sheet flows to low areas. The stormwater management system will replicate similar practices. Stormwater from impervious areas on the site is designed to be treated with a vegetated filter strip and an infiltration area. This design method was chosen on this site due to the minor amount of impervious surface and the uniform grade of the access road. Vegetated filter strips are considered standard stormwater management practices with runoff reduction volume capacity. The total disturbance for the project will be on the order of 1.76± acres. The proposed development will result in an increase of impervious cover by 0.64± acres. 5.0 Post-Development Stormwater Analysis The post-development conditions were analyzed using the HydroCAD computer modeling program. Six (6) subcatchments were used to represent the post development drainage conditions of the site in the areas of the proposed BESS development. Site improvements to the property will consist of approximately 620 +/- LF of access road, a BESS equipment pad, and perimeter fencing. Also included, as permanent elements of the development, is the on-site stormwater management area depicted as a vegetated filter strip and an infiltration area. This vegetated 5 900 Route 146, Clifton Park, New York 12065 phone(518)371-7621 ENVIRONMENTAL DESIGN ect) PARTNERSHIP, LLP. filter strip and infiltration area have been designed to provide treatment and attenuation of stormwater runoff from the proposed impervious surfaces on the site. Runoff from the undeveloped portion of the project site, outside of the stormwater management areas, will sheet flow off site, which is similar to predevelopment drainage patterns. The post-development ground cover Curve Numbers (CN) are listed in Table 3. Table 3: Post-Development Ground Cover Post-Development Ground Cover Description Curve Number Meadow, Non-grazed, HSG B 58 Meadow, Non-grazed, HSG D 78 Woods, Fair, HSG B 60 Woods, Fair, HSG D 79 Impervious 98 The weighted CN for the post-development conditions for the site is approximately 63. The HydroCAD model results for the post-development conditions are included within Attachment B. The contributing area to each stormwater management area is identified in Figure 3. Table 4 presents a summary of the post-development stormwater peak discharge for the 1 year, 10 year and 100-year design storm events at the respective Design Points. The 1-Year design storm shows an increase in runoff from the proposed project. The peak runoff rates do not exceed 0.10 cfs and do not increase the flooding risk to the surrounding areas. Table 4: Post-Development Runoff Rates Storm Event Total Discharge (cfs) 1-Year (1.97") 0.36 10-Year (3.36") 5.57 100-Year (5.73") 23.30 5.1 Stormwater Management Area#1 — Vegetated Filter Strip Stormwater Management Area #1 is designed as a vegetated filter strip with a gravel diaphragm. The filter strip and diaphragm will provide treatment and attenuation of 6 900 Route 146, Clifton Park, New York 12065 phone(518)371-7621 ENVIRONMENTAL DESIGN ect) PARTNERSHIP, LLP. stormwater runoff from the impervious access road and concrete equipment pad. Runoff contributing to SMA#1 will be conveyed via shallow concentrated flow and sheet flow. 5.2 Stormwater Management Area#2—Infiltration Area Stormwater Management Area #2 is designed as an infiltration area. The vegetated swale and infiltration area will provide treatment and attenuation of stormwater runoff from the impervious access road and concrete equipment pad. Runoff contributing to SMA #2 will be conveyed via vegetated swale. 5.3 NYS Unified Stormwater Sizing Criteria The area to be disturbed as a result of the proposed development was modeled in HydroCAD under the post-development conditions using two subcatchments (Figure 3) routed into the stormwater management areas. The contributing area of each stormwater management area is identified in Figure 3. The post-development stormwater management system has been designed based on the Unified Stormwater Sizing Criteria as described in the following sections. 5.3.1 Water Quality(WQJ In general, small storm events and the initial runoff from larger storm events are an environmental concern as this stormwater runoff typically contains roadway pollutants and thermal energy stored by the asphalt. In accordance with the Design Manual, this initial runoff is designated as the Water Quality Volume (WQv) and special attention is given to this volume of runoff to meet water quality objectives. The Design Manual identifies several standard practices, such as the proposed infiltration basins which are acceptable for water quality treatment. These acceptable Stormwater Management Practices (SMPs) can capture and treat the full water quality volume (WQv), are capable of 80% TSS removal and 40% TP removal, have acceptable longevity in the field, and have pretreatment mechanism. The water quality storage volume, WQ,,, is calculated as follows: _ P •R,, A W Q° 12 Where: WQv= water quality volume (acre-feet) P = 90% rainfall event number R = 0.05+O.009(I), where I is percent impervious cover A = site area (acres), impervious area used with I = 100% 7 900 Route 146, Clifton Park, New York 12065 phone(518)371-7621 ENVIRONMENTAL DESIGN ect) PARTNERSHIP, LLP. Table 5: Required Water Quality Volume Drainage P Rv A (Acres) Required WQ,(cf) Provided WQv (cf) Area SMA#1 1.00 0.95 0.24 828 828 SMA#2 1.00 0.52 0.71 1,338 1,338 5.3.2 Runoff Reduction Volume (RRv) The Design Manual specifies that runoff shall be reduced by 100% of the site WQv using standard SMPs with RRv capacity and green infrastructure techniques. The proposed project area on the site is approximately 1.76 acres. The total watershed area contributing to the SMA for analysis is approximately 0.95 acres, with a total post-development impervious area on the order of 0.64 acres. The resulting RRv for these site coverages is computed as 828 CF. Runoff reduction will be provided by standard SMP's with RRv capacity and Green Infrastructure Practices. (See Appendix A for summary of calculations) 5.3.2.1 Stormwater Management Practices (SMP's) An infiltration area has been proposed to collect and treat the stormwater runoff from the site. The infiltration area is considered a standard stormwater treatment practice with RRv capabilities. The RRv provided by the infiltration basin is 1,338 CF. 5.3.2.2 Green Infrastructure Practices The vegetated filter strip is considered a green infrastructure practice. The RRv provided by the practice is on the order of 828 CF. Greater than the minimum RRv required. The following Table provides a summary of the Runoff Reduction provided for the proposed development, based on each management practice and technique. Table 6: Runoff Reduction Volume Summary Runoff Reduction Technique RRv (cf) Vegetated Filter Strip 828 Infiltration Basin 1,338 Total Site Reduction 2,166 WQv. Reduction >100% Many of the green infrastructure practices recommended in the Design Manual were not applied to the stormwater management design on this site due to either site restrictions or the use of more feasible green infrastructure in place of the more restrictive and/or maintenance 8 900 Route 146, Clifton Park, New York 12065 phone(518)371-7621 ENVIRONMENTAL DESIGN ect) PARTNERSHIP, LLP. intensive practices. The following table discusses why the unused green infrastructure practices were not feasible. Table 7: Non-Feasible Green Infrastructure Practices Green Infrastructure Reason use is not feasible Practice Vegetated Swales There are no swales proposed to receive runoff from impervious areas onsite Trees will be saved on the site to the greatest extent possible.Trees will also be planted to maintain a buffer from the surrounding properties to the proposed Tree Planting/Tree Pit site,though the resulting runoff reduction value for adding additional trees is minimal. Conservation of Natural Natural areas will be conserved on site as much as possible, but the resulting Areas runoff reduction value is minimal. Stream Daylighting No existing piped streams are located on the site. Green Roofs There is no building construction proposed as part of the project Stormwater Planters The proposed practices were deemed more economically feasible and effective as opposed to stormwater planters.Additionally,they require less maintenance. Rain Barrels/Cisterns Rain Barrels/Cisterns would require the ability to use the water between storm events which is not feasible for this project type. Rain Gardens Rain gardens are not recommended for commercial applications as well as not economically feasible. Disconnection of There is no building construction proposed as part of the project Rooftop Runoff 5.3.3 Channel Protection (Cpv) In accordance with the Design Manual, stream channel protection, designed to protect stream channels from erosion, is accomplished by providing 24-hour extended detention of the one- year, 24-hour storm event. The Cpv requirement is typically satisfied by providing additional storage above the water quality (WQv) volume. According to Chapter 4 of the Design Manual, the stream channel protection requirement does not apply when the entire channel protection volume is reduced through green infrastructure or infiltration systems. The stormwater management practice onsite is designed as a green infrastructure practice; additionally, stormwater modelling indicates the proposed stormwater management areas designed to fully attenuate and infiltrate the contributing stormwater runoff for stormwater events up to the 100-Year design storm. 5.3.4 Overbank Flood(Qp) Overbank Flood Control Criteria has been established to limit the frequency and magnitude of out-of-bank flooding generated through changes in runoff characteristics as a result of 9 900 Route 146, Clifton Park, New York 12065 phone(518)371-7621 ENVIRONMENTAL DESIGN eco PARTNERSHIP, LLP. increased impervious surface area. In accordance with the Design Manual, providing sufficient storage volume to attenuate the post development 10-year, 24-hour peak discharge rate to the equivalent pre-development discharge rate controls overbank flooding. The 10-year design storm event was analyzed using the HydroCAD stormwater modeling program (TR-20) under the post-development drainage conditions shown on Figure 3. Using a 10-year, 24-hour design storm of 3.36 inches, the stormwater management area was designed with sufficient storage volume to limit the post-development 10-year, 24-hour peak discharge rate to the pre-development discharge rate. The following table presents the pre- and post- development discharge rates for the offsite discharge. As indicated, the post-development discharge rate is less than the pre-development rate as required. Table 8: Overbank Flow Runoff Summary 10-year (3.36") runoff rate (cfs) Predevelopment Post-Development DP-1 5.57 5.57 5.3.5 Extreme Storm (Qf) In accordance with the Design Manual, the stormwater management system must attenuate the post development 100-year, 24-hour peak discharge rate to the predevelopment rate while providing safe passage of this storm event. The 100-year storm event was analyzed using the HydroCAD stormwater modeling program (TR-20) under the post-development drainage conditions shown in Figure 3. Using a 100-year, 24-hour design storm of 5.73 inches, the stormwater management areas were designed with sufficient storage volume to limit the post-development 100-year, 24-hour peak discharge rate to the predevelopment discharge rate. The following table presents the pre and post development discharge rates for the offsite discharge. As indicated, the post-development discharge rate is less than the predevelopment rate as required. Table 9: Extreme Storm Runoff Summary 100-year (5.73") runoff rate (cfs) Predevelopment Post-Development DP-1 23.91 23.30 10 900 Route 146, Clifton Park, New York 12065 phone(518)371-7621 ENVIRONMENTAL DESIGN eco PARTNERSHIP, LLP. 6.0 Summary Development of the proposed project site will alter the stormwater drainage characteristics of the site; impervious area will be added in the form of an improved compacted gravel or paved access road, BESS, and an equipment pad. Changes to the stormwater drainage characteristics of the site have been evaluated in accordance with the Design Manual. The proposed stormwater management system has been designed to comply with the recommendations in the Design Manual and the NYSDEC SPCG as it relates to maintaining sheet flow, providing water quality/runoff reduction/channel protection volume, overbank flood control and extreme flood control for new development projects. The proposed stormwater management system has been designed to attenuate and treat the stormwater runoff generated from the contributing areas for storm events to the pre- development rates, up to and including the 100-Year design storm event. The proposed stormwater management design includes the use of a vegetated filter strip. Stormwater modeling results indicate the ability to reduce the overall post-development discharge rate from the site as summarized in Table 10.

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.nres.usda.gov/wps/ portal/nres/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=nres)or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_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 Custom Soil Resource Report 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 6 Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 8 Custom Soil Resource Report 3 Soil Map 371340 371420 371500 371580 371690 371740 371820 371900 371980 3720Fi0 42o 35'43"N - - 41 I 42o 35 43"N a . 31 4 v i � o o 4 0 _ INK i I Jq Mapm- n, I' tthisxsc -- 42o 35 27"N 420 35 27"N 371340 371420 371500 371580 371660 371740 3718M 371900 371980 372060 3 3 Fn in Map Scale:1:3,390 if printed on A landscape(11"x 8.5")sheet " Meters o NN 0 50 100 200 300 /V 0 150 300 600 900 Map projection:Web Mercator Comer coordinates:WGS84 Edge tics:UTM Zone 18N WGS84 9 Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of Interest(AOI) Spoil Area The soil surveys that comprise your AOI were mapped at Area of Interest(AOI) 1:20,000.

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 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. 11 Custom Soil Resource Report 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 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. 12 Custom Soil Resource Report Tompkins County, New York HmB—Honeoye gravelly silt loam, 2 to 8 percent slopes Map Unit Setting National map unit symbol: 2w3p1 Landscape: Till plains Elevation: 260 to 1,780 feet Mean annual precipitation: 31 to 57 inches Mean annual air temperature: 41 to 50 degrees F Frost-free period: 100 to 190 days Farmland classification: All areas are prime farmland Map Unit Composition Honeoye and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

This project has been assigned Project Code 2026-0061029 and all future correspondence should clearly reference this number. Please carefully review this letter. Ensuring Accurate Determinations When Using IPaC The Service developed the IPaC system and associated species' determination keys in accordance with the Endangered Species Act of 1973 (ESA; 87 Stat. 884, as amended; 16 U.S.C. 1531 et seq.) and based on a standing analysis.All information submitted by the Project proponent into IPaC must accurately represent the full scope and details of the Project. Failure to accurately represent or implement the Project as detailed in IPaC or the Northern Long-eared Bat and Tricolored Bat Range-wide Determination Key (Dkey), invalidates this letter.Answers to certain questions in the DKey commit the project proponent to implementation of conservation measures that must be followed for the ESA determination to remain valid. Determination for the Northern Long-Eared Bat and/or Tricolored Bat Based upon your IPaC submission and a standing analysis, your project has reached the following effect determinations: Species Listing Status Determination Northern Long-eared Bat (Myotis septentrionalis) Endangered No effect Project code: 2026-0061029 IPaC Record Locator: 873-177993024 03/11/2026 14:53:48 UTC To make a no effect determination, the full scope of the proposed project implementation (action) should not have any effects (either positive or negative), to a federally listed species or designated critical habitat. Effects of the action are all consequences to listed species or critical habitat that are caused by the proposed action, including the consequences of other activities that are caused by the proposed action.A consequence is caused by the proposed action if it would not occur but for the proposed action and it is reasonably certain to occur. Effects of the action may occur later in time and may include consequences occurring outside the immediate area involved in the action. (See §402.17). Under Section 7 of the ESA, if a federal action agency makes a no effect determination, no consultation with the Service is required(ESA§7). If a proposed Federal action may affect a listed species or designated critical habitat, formal consultation is required except when the Service concurs, in writing, that a proposed action "is not likely to adversely affect" listed species or designated critical habitat [50 CFR §402.02, 50 CFR§402.13]. Other Species and Critical Habitat that May be Present in the Action Area The IPaC-assisted determination key for the northern long-eared bat and tricolored bat does not apply to the following ESA-protected species and/or critical habitat that also may occur in your Action area: ■ Monarch Butterfly Danaus plexippus Proposed Threatened You may coordinate with our Office to determine whether the Action may affect the animal species listed above and, if so, how they may be affected. Next Steps If there are no updates on listed species, no further consultation/coordination for this project is required with respect to the species covered by this key. However, the Service recommends that project proponents re-evaluate the Project in IPaC if: 1)the scope, timing, duration, or location of the Project changes (includes any project changes or amendments); 2) new information reveals the Project may impact(positively or negatively) federally listed species or designated critical habitat; or 3) a new species is listed, or critical habitat designated. If any of the above conditions occurs, additional coordination with the Service should take place to ensure compliance with the Act. If you have any questions regarding this letter or need further assistance, please contact the New York Ecological Services Field Office and reference Project Code 2026-0061029 associated with this Project.

Therefore, no consultation with the U.S. Fish and Wildlife Service pursuant to Section 7(a)(2) of the Endangered Species Act of 1973 (87 Stat. 884, as amended 16 U.S.C. 1531 et seq.)is required for those species. QUALIFICATION INTERVIEW 1. Does the proposed project include, or is it reasonably certain to cause, intentional take of listed bats or any other listed species? Note:Intentional take is defined as take that is the intended result of a project.Intentional take could refer to research,direct species management,surveys,and/or studies that include intentional handling/encountering, harassment,collection,or capturing of any individual of a federally listed threatened,endangered or proposed species? No 2. Is the action area wholly within Zone 2 of the year-round active area for northern long- eared bat and/or tricolored bat? Automatically answered No 3. Does the action area intersect Zone 1 of the year-round active area for northern long-eared bat and/or tricolored bat? Automatically answered No 4. Does any component of the action involve leasing, construction or operation of wind turbines?Answer 'yes' if the activities considered are conducted with the intention of gathering survey information to inform the leasing, construction, or operation of wind turbines. No 5. Is the proposed action authorized, permitted, licensed, funded, or being carried out by a Federal agency in whole or in part? Note for projects in Pennsylvania:Projects requiring authorization under Section 404 of the Clean Water Act and/or Section 10 of the Rivers and Harbors Act would be considered as having a federal nexus.Since the U.S. Army Corps of Engineers(Corps)has issued the Pennsylvania State Programmatic General Permit(PASPGP), which may be verified by the PA Department of Environmental Protection or certain Conservation Districts,the need to receive a Corps authorization to perform the work under the PASPGP serves as a federal nexus.As such, if proposing to use the PASPGP,you would answer`yes'to this question.

[Semantic] Is the action area located within 0.5 miles of a known bat hibernaculum or winter roost? Note: The map queried for this question contains proprietary information and cannot be displayed. If you need additional information, please contact your state wildlife agency. Automatically answered No 7. Does the action area contain any winter roosts or caves (or associated sinkholes, fissures, or other karst features), mines, rocky outcroppings, or tunnels that could provide habitat for hibernating bats? No 8. Will the action cause effects to a bridge? Note: Covered bridges should be considered as bridges in this question. No 9. Will the action result in effects to a culvert or tunnel at any time of year? No 10. Are trees present within 1000 feet of the action area? Note:If there are trees within the action area that are of a sufficient size to be potential roosts for bats answer "Yes".If unsure,additional information defining suitable summer habitat for the northern long-eared bat and tricolored bat can be found in Appendix A of the USFWS'Range-wide Indiana Bat and Northern long-eared bat Survey Guidelines at:https://www.fws.gov/media/range-wide-indiana-bat-and-northern-long-eared-bat-survey- guidelines. Yes 11. Does the action include the intentional exclusion of bats from a building or building-like structure? Note:Exclusion is conducted to deny bats'entry or reentry into a building.To be effective and to avoid harming bats,it should be done according to established standards.If your action includes bat exclusion and you are unsure whether northern long-eared bats or tricolored bats are present,answer"Yes."Answer"No"if there are no signs of bat use in the building/structure.If unsure,contact your local Ecological Services Field Office to help assess whether northern long-eared bats or tricolored bats may be present.Contact a Nuisance Wildlife Control Operator(NWCO)for help in how to exclude bats from a structure safely without causing harm to the bats(to find a NWCO certified in bat standards,search the Internet using the search term"National Wildlife Control Operators Association bats").Also see the White-Nose Syndrome Response Team's guide for bat control in structures. No 12. Does the action involve removal, modification, or maintenance of a human-made building- like structure (barn, house, or other building) known or suspected to contain roosting bats?

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act(Act) of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the IPaC website at regular intervals during project planning and implementation for updates to species lists and information.An updated list may be requested through the IPaC system by completing the same process used to receive the enclosed list. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) Project code: 2026-0086469 05/06/2026 18:23:06 UTC (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: https://www.fws.gov/sites/default/files/documents/endangered-species-consultation- handbook.pdf Migratory Birds: In addition to responsibilities to protect threatened and endangered species under the Endangered Species Act(ESA), there are additional responsibilities under the Migratory Bird Treaty Act(MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to protect native birds from project-related impacts.Any activity resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more information regarding these Acts see https://www.fws.gov/program/migratory-bird-permit/what-we-do. It is the responsibility of the project proponent to comply with these Acts by identifying potential impacts to migratory birds and eagles within applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan (when there is no federal nexus). Proponents should implement conservation measures to avoid or minimize the production of project-related stressors or minimize the exposure of birds and their resources to the project-related stressors. For more information on avian stressors and recommended conservation measures see https:// www.fws.gov/library/collections/threats-birds. In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities that might affect migratory birds, to minimize those effects and encourage conservation measures that will improve bird populations. Executive Order 13186 provides for the protection of both migratory birds and migratory bird habitat. For information regarding the implementation of Executive Order 13186, please visit https://www.fws.gov/partner/council-conservation- migratory-birds. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Code in the header of this letter with any request for consultation or correspondence about your project that you submit to our office. 2 of 7 Project code: 2026-0086469 05/06/2026 18:23:06 UTC Attachment(s): ■ Official Species List OFFICIAL SPECIES LIST This list is provided pursuant to Section 7 of the Endangered Species Act, and fulfills the requirement for Federal agencies to "request of the Secretary of the Interior information whether any species which is listed or proposed to be listed may be present in the area of a proposed action".
