This Community Solar system will be constructed on a collection of open fields owned by John Rancich. As we embark on the application process, Nexamp hopes to learn more about the Town’s desires for ongoing solar development, and ultimately, we are seeking feedback that will help our team adjust our final design as we head into environmental and site plan approval processes. The proposed solar array is a single-axis sun-tracking system, which optimizes system performance by tracking the sun from east to west throughout the day. The Utility-approved system is 5MWac and should occupy less than 30 acres of fenced area each. The proposed project will also include construction of a new gravel access road leading to the proposed solar array area, Single-Axis Tracker solar racking, no more than two inverter/transformer equipment pads, Solar Energy Storage, new overhead utility poles, and an eight-foot fence around the perimeter of each solar array. There will be no significant proposed grading, except for some stormwater management systems to limit erosion and runoff. At the conclusion of construction, the soil will be seeded with a locally appropriate seed mix to prevent soil damage and promote deep root growth. Vegetation management within the solar array would be accomplished by mowing and/or sheep grazing within the fenced area. At the end of their lives, the solar arrays will be decommissioned, and the site restored back to the current existing condition, per Town Code requirements. Included in this packet is an overview of the project, including system design, environmental conditions, the estimated permitting process, and a sample construction schedule. Additionally, should the board members or Town employees want to better familiarize themselves with Nexamp and its history, we have provided a brief overview of our company as well. We sincerely thank all members of the board for their consideration, and we hope that this pre- application process sets the groundwork for a productive partnership in the future.

Carrowmoor Solar – Project Narrative – Town of Ithaca Existing Site Conditions Summary As part of its initial due diligence related to the site, Nexamp has worked with civil and environmental contractors to conduct extensive physical, environmental, and permitting diligence on the site. Pre- Permitting meetings with the Town have informed our current design, and as designed the site in question will not require any environmental permits other than those associated with its SWPPP and eventual SPDES permit application. Phase one environmental studies have found no evidence of Recognized Environmental Conditions (RECs), Historical Recognized Environmental Conditions (HRECs) or Controlled Recognized Environmental Conditions (CRECs) within the fenced area of the site. We anticipate that our project will be declared a Type I action, subject to full SEQR review by the Town of Ithaca Planning Board. Phase I Environmental reports can be shared with the Town upon request. The Phase I study was conducted by our civil engineering partners at LaBella PLLC, and was completed pursuant to ASTM, E1527-13 standards. Tax Parcel Currently, the project is slated for construction on a single parcel; 27-1.-15.2, located in the Town’s Low Density Residential District. Wetlands & Drainage While this site does contain several sections of poorly drained soils, there are no DEC recognized wetlands present on the site. Site analysis shows several potentially non-jurisdictional wetlands on the site. Design has been modified to not permanently disturb these wetlands. Construction controls protecting these potential wetlands have been incorporated into our civil design set and will remain in place until the surrounding installation is complete and ground is stabilized. Wildlife Preliminary analysis of the NYS Environmental Resource Mapper and NYS EAF Mapper have shown no species of interest, or endangered species within the project area, or area of impact. USFWS has indicated two endangered species in the area: the Monarch Butterfly and the Northern Long Eared Bat. No habitat will be destroyed or deteriorated by the project, and thus we expect no impacts to be found for either species. Further coordination with these agencies will be conducted during the SEQR process. NYS DEC has issued a letter of no impact affirming these findings as of February 16th, 2023. Archaeological Resources Per Nexamp’s Letter of No Impact, issued by NYSHPO on April 3rd, 2023, there are no historic properties of any archaeological or historic importance affected by the proposed development. Soils While the facility does fall within the TOMP002 Agricultural District, no USDA prime soils exist on the property. Two small pockets of NYSDAM MSG 3 Soils are located on site, but minimal impacts to said soils will take place due to the nature of the installation and small volume of necessary grading.

The parcel is not part of a required open space area or park-side area. The facility should be designated as a Large-Scale Ground Mounted PV system. It exists entirely on one parcel, and the solar facility footprint does not exceed 35 acres. All project equipment is setback are a minimum of 75ft, access roads occur within this setback to comply with road placement regulations. Interconnection: This is a 5MWac, 20MWh Energy Storage facility connected via local distribution grid to the West Hill Substation. The facility was approved by NYSEG in December of 2022. The system is planning to Interconnect via existing poles on Mecklenburg rd. at the existing Crown Castle Communications tower maintenance entrance. Slight changes to the interconnection layout are required to make the facility compliant with the Town’s 75’ setback requirement, but a forthcoming design change will place all utility and customer owned equipment outside of setback boundary. Conduit within the system fence, and all conduit Carrowmoor Solar – Project Narrative – Town of Ithaca heading to the POI will remain underground, buried to NYSDAM and Town of Ithaca standards, to the extent approved by the utility. Racking: Racking suppliers are somewhat fluid at this stage, due to the early age of the project and lack of visibility into later-stage availability. Regardless of supplier, the system will be a 2- Portrait single-axis tracker system, mounted to the ground via either steel I beams or ground screws. The overall system height should not be more than 17-18 ft at peak tilt. Panels utilized will be a PV variety, covered with anti-glare coating to meet the Town of Ithaca’s requirements. Roads: Roads for this project have been located and constructed to preserve safety and comply with the Town’s soil protection requirements. Utility access will be limited to the existing access road utilized by Crown Castle for tower access. This road will be widened to meet the 20’ requirement of the utility, and where necessary pervious spurs will be installed adjacent to the existing road for pole or pad access. Construction and maintenance access will be conducted via the westernmost access road, adjacent to the westernmost abutter property line to adhere to code. The road will continue through the facility past the energy storage facilities to the rear fence for fire access as directed by the IFD. Construction and access roads will be built at grade where possible, but several raised areas will occur to preserve existing drainage patters and ensure adequate stormwater protections. A temporary laydown area will be constructed off the Construction and Maintenance access road for storage of all construction material, equipment, and employee parking throughout the systems construction. This laydown area will be removed, excess stone spread, and soil seeded and remediated prior to final completion. Stormwater: Apart from the potentially pervious access road improvements installed along the existing Crown Castle access area, all roads will be impervious surfaces treated to NYSDEC standards. A SWPPP and stormwater narrative have been included in our application materials to better outline these features and their respective functionality. Extensive temporary protections will be installed during construction to prevent runoff and soil damage, including silt fencing around all existing internal wetlands, and areas of disturbance. A 5-acre waiver is being sought, so stormwater inspections will take place bi-weekly throughout construction. DEC reports will be shared with Town engineers at their request. Screening and Vegetation: The project as designed preserves substantial natural screening to the North, West and East. This natural, native screening is going to be preserved to substantially screen the project. To augment this natural screening, ±78 coniferous trees have been proposed along Mecklenburg Rd. During and following construction, Nexamp plans to seed the facility with Ernst Buzz and Fuzz, an ASGA-approved grazing and pollinator friendly seed mix that will promote foraging and pollinator habitat in the project area. Fencing: The project was designed with 8’ farm fence throughout the site, satisfying NEC requirements. Posts will be PT wood, save gate entrances which will be standard metal poles for stability. The fence is small-wildlife friendly, made of galvanized steel 2.5” mesh, and will be installed at 3” above grade. Construction Practices: Nexamp; as the developer and contractor for the project will, manage all subcontractors and steer the project with its own Project Management team. Per Town and State Requirements, the project will be constructed under NYSDAM guidelines, dictating soil management and storage in addition to environmental monitoring requirements. The facility Carrowmoor Solar – Project Narrative – Town of Ithaca does not impact any prime soils, so environmental monitoring will be handled by on-site, Nexamp Project Managers. NYSDEC stormwater requirements and installations will be handled under the SPDES permit to be issued to the company. Operations and Maintenance: Nexamp Asset Management Services, LLC, a subsidiary of Nexamp Inc, will be the long-term asset manager for the system. Nexamp has never sold one of its NYS assets and has only parted with a few of the 129+ Community Solar Systems it has developed and constructed nationwide. As such, we feel confident in the promises made in our Operations and Maintenance Plan, included in our submission.

The pair launched NexGen Energy Solutions, a turnkey provider of renewable energy and carbon solutions, in their hometown of North Andover, Massachusetts. NexGen became Nexamp later in 2007. During the early years, Nexamp delivered a variety of energy systems for residential, commercial, municipal and agricultural customers. Energy solutions offered included solar PV, solar thermal, micro- wind, geothermal heating and cooling, and a wide array of energy efficiency services. In 2011, Nexamp shifted its focus fully toward commercial and industrial scale solar facilities, working with businesses, municipalities, and property owners that wanted to realize the various benefits of renewable solar generation. 2015 marked Nexamp’s first community solar project and the beginning of a new chapter for the company. Leveraging its integrated approach of developing, building, owning and operating solar plants, Nexamp turned its focus to community solar, and alongside that the mission of making the benefits of solar power available to everyone—homeowners, renters, non-profits, small businesses, farms and more. Nexamp was named NECEC Clean Energy Company of the Year in 2015 and a Solar Power World Top 3 Commercial Solar Developer in 2017. In 2016, Mitsubishi’s Diamond Generating Corporation made a significant investment in Nexamp, and in 2018 the group made an additional investment that gave it a controlling interest. Serving a rapidly expanding network of individuals, property owners, businesses, and communities that benefit from its nationally distributed portfolio of solar assets, Nexamp is a Massachusetts-based, nationally headquartered solar company that is laying the groundwork for a cleaner, more secure and resilient energy future. Throughout 2022, Nexamp permitted and financed more than 250MWs of community solar projects in 12 states, with more than half of that total capacity occurring in New York State. Our team expects to bring another 250MWs through permitting and financing through 2023, adding to our industry-leading community solar portfolio. Even in uncertain times, our team has considered to set the bar for not only developing sustainable projects but managing them and working with our partner communities to build lasting relationships.

We appreciate the opportunity to provide the following comments pertaining to threatened or endangered species under our jurisdiction pursuant to the Endangered Species Act (ESA; 87 Stat. 884, as amended; 16 U.S.C. 1531 et seq.). We understand that there is no federal nexus (i.e., funding, permitting) associated with this project. The proposed project involves the construction of a solar facility on an approximately 55-acre parcel previously used for agriculture. Some trees are present on the site however project documents indicate removal is not anticipated. Labella Associates, working on behalf of Nexamp, has determined that the proposed project would not result in adverse impacts to the federally listed Endangered Northern long eared bat (Myotis septentrionalis;). The Service agrees that adverse effects to this species are not reasonably certain to occur given that tree removal is not proposed and there are no known roosts within 150 feet or hibernacula within 0.25 mile of the project. On September 14, 2022, the Service published a proposal in the Federal Register to list the tricolored bat (Perimyotis subflavus) as endangered under the ESA. The Service has up to 12 months from the date the proposal published to make a final determination, either to list the tricolored bat under the ESA or to withdraw the proposal. The Service determined the bat faces extinction primarily due to the rangewide impacts of white-nose syndrome (WNS), a deadly fungal disease affecting cave-dwelling bats across North America. Because tricolored bat populations have been greatly reduced due to WNS, surviving bat populations are now more vulnerable to other stressors such as human disturbance and habitat loss. Species proposed for listing are not afforded protection under the ESA; however, as soon as a listing becomes effective (typically 30 days after publication of the final rule in the Federal Register), the prohibitions against jeopardizing its continued existence and “take” will apply. Therefore, if proposed projects have the potential to adversely affect tricolored bats after the potential new 2 listing goes into effect, we recommend that the effects of the project on tricolored bat and their habitat be analyzed to determine whether authorization under ESA section 7 or 10 is necessary. Please contact our office for assistance in determining if take is reasonably likely to occur for this species for your proposed projects. The monarch butterfly (Danaus plexippus) is currently a candidate for listing under the Endangered Species Act (Federal Register :: Endangered and Threatened Wildlife and Plants; 12-Month Finding for the Monarch Butterfly). While the monarch butterfly may be identified through the U.S. Fish and Wildlife Service’s (Service) Information, Planning and Consultation (IPaC) program official species list requests, there is no requirement under section 10 (non- federal agency involvement) to coordinate with the Service on candidate, proposed, or listed species. However, we encourage project sponsors to take advantage of any opportunity they may have to conserve the monarch butterfly. We also continue to encourage our project sponsors to consider incorporating habitat restoration or enhancement measures into project plans that benefits the monarch butterfly and other pollinator species No further coordination with the Service is required pursuant to the ESA for this project. Should project plans change, or if additional information on listed or proposed species or critical habitat becomes available, this determination may be reconsidered. The most recent compilation of federally listed and proposed endangered and threatened species in New York is available for your information. Until the proposed project is complete, we recommend that you check our website regularly to ensure that listed species presence/absence information for the proposed project is current.* This letter does not exempt the project proponent from obtaining approvals or permits that may be required by State or Federal agencies. Further, this letter does not convey any authorization for take under the ESA or any other authorities. Any new information regarding the proposed project and its potential to impact listed species should be coordinated with both this office and with the New York State Department of Environmental Conservation. We appreciate the opportunity to review this project. If you require additional information or assistance, please contact Tim Sullivan at tim_r_sullivan@fws.gov. Future correspondence with us on this project should reference project file 2023-0033936.

Based upon the review of your inquiry,DEC has the following comments: PROTECTION OF WATERS An unnamed tributary of Cayuga Lake (NYS Water Index #:Ont-66-12-P 296-76-2,Class C,non- navigable)is located within the identified parcel,however,it appears the work will be avoiding any impacts to this waterbody therefore a Protection of Waters Permit is not required for the proposed work. If a permit is not required,please note,however,the project sponsor is still responsible for ensuring that work shall not pollute any stream or waterbody.Care shall be taken to stabilize any disturbed areas promptly after construction,and all necessary precautions shall be taken to prevent contamination of the stream by silt,sediment,fuels,solvents,lubricants,or any other pollutant associated with the project. FRESHWATER WETLANDS The project site is not within a New York State protected Freshwater Wetland.The project sponsor should contact town officials and the United States Army Corps of Engineers (USACE)Auburn Field Office,at (315)255-8090,however,for any permitting they might require.Please note that if a permit from the USACE is required for the proposed work,a Section 401 Water Quality Certification may be required from DEC. STATE-LISTED SPECIES No records of sensitive resources were identified by this review.The absence of data does not necessarily mean that rare or state-listed species,natural communities or other significant habitats do not exist on or adjacent to the proposed site.Rather,our files currently do not contain information which indicates their presence.For most sites,comprehensive field surveys have not been conducted.We cannot provide a ,JrNEWYORK Department of 2.oppofliuNly Environmental Conservation RE:Carrowmoor Solar Project Date:2/16)2023 DEC Facility ID#:7-5030-00199 Town of Ithaca,Tompkins County Jurisdiction Determination definitive statement on the presence or absence of all rare or state-listed species or significant natural communities.Depending on the nature of the project and the conditions at the project site,further information from on-site surveys or other sources may be required to fully assess impacts on biological resources. STATE POLLUTANT DISCHARGE ELIMINATION SYSTEM (SPDES) Sail disturbances of one or more acres of land from construction activities must obtain permit coverage under the NYSDEC SPDES General Permit for Stormwater Discharges from Construction Activities (GP 0-20-001)by submitting a Notice of Intent and developing &implementing a Stormwater Pollution Prevention Plan.For further information please consult with Julie Melancon in DEC’s Division of Water at 315-426-7550 or review the NYSDEC Stormwater webpage.Additionally,please see the attached solar panel stormwater permitting guidance document.If the project does not meet ALL criteria for Scenario 1, including alignment of solar panels along the contour,the SWPPP must address post-construction stormwater practices designed in accordance with the sizing criteria identified in the New York State Stormwater Management Design Manual. CULTURAL RESOURCES We have reviewed the statewide inventory of archaeological resources maintained by the New York State Museum and the New York State Office of Parks,Recreation,and Historic Preservation.These records indicate that the project is not located within an area considered to be sensitive with regard to archaeological resources.For more information,please visit the New York State Office of Historic Preservation website at http://www.nysparks.com/shpo/.

Part 2 is designed to help the lead agency inventory all potential resources that could be affected by a proposed project or action. We recognize that the lead agency=s reviewer(s) will not necessarily be environmental professionals. So, the questions are designed to walk a reviewer through the assessment process by providing a series of questions that can be answered using the information found in Part 1. To further assist the lead agency in completing Part 2, the form identifies the most relevant questions in Part 1 that will provide the information needed to answer the Part 2 question. When Part 2 is completed, the lead agency will have identified the relevant environmental areas that may be impacted by the proposed activity. If the lead agency is a state agency and the action is in any Coastal Area, complete the Coastal Assessment Form before proceeding with this assessment. Tips for completing Part 2: •Review all of the information provided in Part 1. •Review any application, maps, supporting materials and the Full EAF Workbook. •Answer each of the 18 questions in Part 2. •If you answer “Yes” to a numbered question, please complete all the questions that follow in that section. •If you answer “No” to a numbered question, move on to the next numbered question. •Check appropriate column to indicate the anticipated size of the impact. •Proposed projects that would exceed a numeric threshold contained in a question should result in the reviewing agency checking the box “Moderate to large impact may occur.” •The reviewer is not expected to be an expert in environmental analysis. •If you are not sure or undecided about the size of an impact, it may help to review the sub-questions for the general question and consult the workbook. •When answering a question consider all components of the proposed activity, that is, the Awhole action@. •Consider the possibility for long-term and cumulative impacts as well as direct impacts. •Answer the question in a reasonable manner considering the scale and context of the project. 1.Impact on Land Proposed action may involve construction on, or physical alteration of,† NO † YES the land surface of the proposed site. (See Part 1. D.1) If “Yes”, answer questions a - j. If “No”, move on to Section 2. Relevant Part I Question(s) No, or small impact may occur Moderate to large impact may occur a.

Other impacts: ______________________________________________________ __________________________________________________________________ 9 9 Please see Part 3 Attachment Full Environmental Assessment Form Part 3 - Evaluation of the Magnitude and Importance of Project Impacts and Determination of Significance Part 3 provides the reasons in support of the determination of significance. The lead agency must complete Part 3 for every question in Part 2 where the impact has been identified as potentially moderate to large or where there is a need to explain why a particular element of the proposed action will not, or may, result in a significant adverse environmental impact. Based on the analysis in Part 3, the lead agency must decide whether to require an environmental impact statement to further assess the proposed action or whether available information is sufficient for the lead agency to conclude that the proposed action will not have a significant adverse environmental impact. By completing the certification on the next page, the lead agency can complete its determination of significance. Reasons Supporting This Determination: To complete this section: •Identify the impact based on the Part 2 responses and describe its magnitude. Magnitude considers factors such as severity, size or extent of an impact. •Assess the importance of the impact. Importance relates to the geographic scope, duration, probability of the impact occurring, number of people affected by the impact and any additional environmental consequences if the impact were to occur. •The assessment should take into consideration any design element or project changes. •Repeat this process for each Part 2 question where the impact has been identified as potentially moderate to large or where there is a need to explain why a particular element of the proposed action will not, or may, result in a significant adverse environmental impact. •Provide the reason(s) why the impact may, or will not, result in a significant adverse environmental impact •For Conditional Negative Declarations identify the specific condition(s) imposed that will modify the proposed action so that no significant adverse environmental impacts will result. •Attach additional sheets, as needed.

The project also includes installing two inverter/transformer equipment pads, solar energy battery storage, new overhead utility (NYSEG) interconnects and poles, an eight-foot tall perimeter fence, stormwater management facilities, access drive, and other site elements. The project is located in the Agricultural Zone and the Large-Scale Photovoltaic Solar Energy System Overlay District, which permit large scale systems with Site Plan Approval by the Planning Board. The Planning Board reviewed a sketch plan for the proposal on June 20, 2023. The proposed action is a Type I Action, pursuant to 6 NYCRR Part 617 (State Environmental Quality Review), because the project includes: (1) an action that involves the physical alteration of 10 acres (617.4 (c)(6)(i); and (2) an action that involves a nonagricultural use occurring wholly or partially within an agricultural district (Pursuant to Agriculture and Markets Law, article 25-AA, sections 303 and 304) (617.4 (c)(8). The project is also a Type I Action pursuant to the Town of Ithaca Town Code Chapter 148, Environmental Quality Review, because it involves the authorization of industrial or commercial uses within a residential or agricultural district applying to a parcel of land of 10 or more acres (148.5.A (1). 1. Impact on Land b. The proposed action may involve construction on slopes of 15% or greater. e. The proposed action may involve construction that continues for more than one year or in multiple phases. f. The proposed action may result in increased erosion, whether from physical disturbance or vegetation removal (including from treatment by herbicides). Briefly describe the impact on land: The 93+/- acre parcel on Mecklenburg Road is currently farmed and contains a telecommunications tower that was approved by the Planning Board in 2016. The parcel is bound on the north by woods and farmland, on the east by farmland, on the south by Mecklenburg Road, and on the west by farmland. This parcel, along with the adjacent farm parcel immediately east (also owned by the applicant), was once part of the “Carrowmoor” development proposal. The Planning Board issued a positive declaration of significance in 2009 for the Carrowmoor mixed-use development project that would consist of 400 +/- residential condominium units, a 2 community center complex, up to 36,000 square feet of neighborhood oriented commercial uses, up to 32 living units in an elderly residential building, a child-care center, and other development. There has been no action on the Carrowmoor residential development proposal since 2009; the proposed solar energy project will largely preclude or substantially reduce the Carrowmoor development proposal. The overall property contains some areas with slopes that exceed 15%, but the project will be located at least 400 feet away from said slopes. The entirety of the solar array footprint will reside in areas with slopes 10% or less, with the majority of the array footprint located in areas with slopes 5% or less. In terms of erosion and physical disturbance, the submitted plans show that there will be limited ground disturbance and grading associated with the project. The solar array will be constructed on a post and rack system with the panels elevated off the ground, so the array itself will cause minimal ground disturbance. This will significantly limit overall site disturbance and will only result in about one acre of impervious surface over the 30+/- acre portion of the property that will be utilized for the solar project. The area underneath and surrounding the panels will be vegetated and will be managed via mowing and/or sheep grazing. Most of the site disturbance will be associated with the installation of the equipment/battery storage pads, gravel access roads, and stormwater management measures such as drainage swales and vegetative filter strips. The project site will be fenced, and special care will be taken to avoid delineated wetlands that are on the site (please see #3 below). The front 35+/- acres of the property will remain in farmland. Additional details relating to the wetlands, erosion controls, and the farmland use are discussed in #’s 3/4/5 and 8 (respectively) below. Although the applicant expects the project to take one year, there is a chance it could take longer to avoid construction during winter months. Based on the above information, impacts identified in this section can be considered small in magnitude. 3. Impacts on Surface Water d. The proposed action may involve construction within or adjoining a freshwater or tidal wetland, or in the bed or banks of any other water body. h. The proposed action may cause soil erosion, or otherwise create a source of stormwater discharge that may lead to siltation or other degradation of receiving water bodies. i. The proposed action may affect the water quality of any water bodies within or downstream of the site of the proposed action. 4. Impact on Groundwater f. Other Impacts: There is a principal aquifer located on a property that is adjacent to the project site. 5. Impact on Flooding d. The proposed action may result in, or require, modification of existing drainage patterns. Briefly describe the impact on surface water and flooding: Waterbodies within or downstream of the site: There are five small wetlands on the property that have been delineated and are included on all of the plans associated with the solar project. The materials show protection of the wetlands during construction, so they will not be disturbed. The 3 application materials include correspondence between the applicant and the NYSDEC and Army Corps of Engineers (ACOE) related to the wetlands. At least three of the wetlands are potentially non- jurisdictional and would not require permits from either agency. The NYSDEC lead agency response letter has noted that the project site is not within a New York State protected Freshwater Wetland. Planning staff contacted the ACOE on August 4, 2023, to discuss the potential wetland permitting that could be required by the organization. A representative from ACOE indicated in an email that the project plans showed “that it looks like they are avoiding the wetlands on the site.” The Army Corps representative noted in the email that the department would review the wetland delineation report to confirm and would “send a letter agreeing with the wetland boundaries” so the applicant and the town would “know that we concur that the project will not impact any wetlands.” Staff followed up with ACOE on August 23, 2023, and received a response that the department was backlogged with many projects and would not be able to review the proposed solar project for “quite some time.” This correspondence has been added to the Planning Department project file. There are no significant adverse environmental impacts expected, given that the wetlands will not be disturbed and will be protected during construction. In addition to the wetlands, there are two small streams on the property (tributaries of Williams Brook and Linderman Creek). One stream is located along the northeast corner of the property, and one is located along the northwest corner of the property. The stream along the northeast is approximately 700+/- feet away from the project; the stream along the northwest is approximately 300+/- feet away from the project. Neither waterbody will be directly impacted by the proposal, and any potential indirect impacts will be mitigated with the proposed stormwater management practices noted below. Soil Erosion, Water Quality, Water Quantity, & Flooding: There is minimal ground disturbance associated with this project and only approximately 1-acre of impervious surface will be created. The solar array is on a rack system that is elevated off the ground, and the proposed equipment/battery pads and access roads will require minimal grading. To mitigate soil migration offsite, the applicant proposes installing silt fencing around the delineated wetlands and down grade from disturbances, creating a stabilized construction entrance, and performing temporary soil stabilization. Permanent stormwater management devices will be installed to maintain sheet flow conditions on the site and to maintain pre-condition drainage patterns and peak discharge rates. After construction, the disturbed areas will be seeded with locally appropriate seed mix to prevent soil damage, promote deep root growth, and provide permanent soil stabilization. The applicant has indicated that there will not be an increase in stormwater runoff from the project area. The applicant proposes to install vegetative filter strips along the equipment/battery storage pads and impervious access road to provide water quality treatment of stormwater runoff that is generated by the proposed project. These and other practices are described in the Stormwater Pollution Prevention Plan (SWPPP) that was submitted to the Town’s Engineering Department for their review and approval. The Engineering Department reviewed a previous iteration of plans, as indicated in their review memorandum, dated July 18, 2023, and deemed the proposed SWPPP to be conceptually acceptable in terms of mitigating environmental impacts related to stormwater. The Engineering Department will review revised materials prior to final site plan approval to ensure that the project is in conformance with applicable stormwater regulations. 4 Briefly describe the impact on groundwater: The Full EAF Part 1 indicates that the project site is located over, or is immediately adjoining, a primary, principal, or sole source aquifer. According to the United States Geological Survey, an aquifer is a body of rock or sediment that is completely saturated, with water in it and all around it. Aquifers can be made of sand, gravel, sandstone, or other rocks that store and transmit water. The NYSDEC categorizes principal aquifers as those “known to be highly productive, or whose geology suggests abundant potential water supply, but which are not intensively used as sources or water supply by major municipal systems at the present time.” Further research from the NYSDEC/ NYS Geographic Information System Clearinghouse website indicates that the project site does not contain an aquifer, but that there is an aquifer located on the adjacent property to the west. On the surface, the aquifer presents itself as a small farm pond. There are no anticipated significant adverse environmental impacts to the principal aquifer with this project, given that (1) the aquifer is not located on the project site, (2) the solar project involves minimal ground disturbance with mitigations to minimize erosion, sedimentation, and stormwater runoff, and (3) there is no development proposed that would necessitate utilizing the aquifer or any other water source on or near the project site. Based on the above information, impacts identified in this section can be considered small in magnitude. 7. Impact on Plants and Animals j. Other impacts: The NYS DEC EAF Mapper Program indicates that the project site may contain animal species listed by the federal government or NYS as endangered or threatened, or that the project site contains areas identified as habitat for an endangered or threatened species. Briefly describe the impact on plants and animals: The project does not include tree removal; and disturbance to existing vegetation will be minimal. The EAF Part 1 notes that the Northern Long-Eared bat was flagged by the US Fish and Wildlife Service’s online database for potential habitat on the project site. However, a letter from the US Fish and Wildlife Service attached to the EAF Part 1 states that “adverse effects to this species are not reasonably certain to occur given that tree removal is not proposed and there are no known roosts within 150 or hibernacula within 0.25 miles of the project.” The project includes a wildlife-friendly, wood and steel fence that will surround the acreage associated with the solar array. This fence will impact large animals (coyote, deer) by forcing them to go around the fenced area. However, the fenced-in area only comprises 30+/- acres of the 93+/- acre property, so there is ample room for larger animals to traverse the property without crossing Mecklenburg Road. The project is not expected to impact animal migration patterns or break up any known ecological/wildlife corridors. The project also includes seeding the site with a grazing and pollinator-friendly seed mix that will promote foraging and pollinator habitat in the project area; and a vegetation management plan that involves mowing outside the fenced-in area and sheep-grazing inside the fenced-in area. The project will apply EPA and DEC-compliant herbicide use that is specific to targeting invasive species that may encroach on the property. However, the overall anticipated adverse impact on plant and animal life associated with the project is expected to be minimal. 5 Based on the above information, impacts identified in this section can be considered small in magnitude. 8. Impact on Agricultural Resources a. The proposed action may impact soil classified within soil group 1 through 4 of the NYS Land Classification System. b. The proposed action may sever, cross, or otherwise limit access to agricultural land (includes cropland, hayfields, pasture, vineyard, orchard, etc.) Briefly describe the impact on agricultural resources: The project site is located on an existing fallow agricultural field that was most recently utilized for row cropping. Most of the 93+/- acre property has been utilized for agricultural purposes, and the area surrounding the project site will continue to be used for agricultural purposes. The proposed solar project will not sever or limit access to the remaining fields on the property. The project site is located within a Tompkins County Agricultural District, although no US Department of Agriculture (USDA) prime soils are present on the site. There are two areas of the property that contain US Department of Agricultural and Markets Mineral Soil Group 3 (MSG3) soils, which are among the highest quality agricultural soils. However, there will be minimal impacts to the soils, due to the nature of the installation (minimal ground disturbance) and the limited grading associated with the project. The project is required to comply with the Town of Ithaca Large-Scale Photovoltaic Systems Construction Standards (§270-219.1. G [2] (c) [6]), along with the NYS Department of Agriculture and Markets Guidelines for Solar Energy Projects – Construction Mitigation for Agricultural Lands (10/18/19). The EAF Part 1 attachments contain a letter from the NYS Department of Agriculture and Markets, dated June 20, 2023, that indicate that the proposed action “will not have an unreasonably adverse effect on the continuing viability of farm enterprises within the Tompkins County Agricultural District or the State environmental plans, policies, and objectives.” The Town of Ithaca has an Agricultural and Farmland Protection Plan that was adopted in November 2011. The proposed solar project is not in conflict with the Plan because the Plan does not contain anything about the use of farmland for large-scale solar system uses. There is one sentence in the Plan associated with renewable energy, but it is related to providing opportunities for small scale use of on-farm energy resources such as solar, wind, biogas, and biomass to support the farm use. Based on the above information, impacts identified in this section would be considered small in magnitude. 9. Impact on Aesthetic Resources a. Proposed action may be visible from any officially designated federal, state, or local scenic or aesthetic resource. c. The proposed action may be visible from publicly accessible vantage points (seasonally or year-round) Briefly describe the impact on aesthetic resources: The solar array will be installed at least 900 feet into the property off of Mecklenburg Road/NYS Route 79. The frontage will be screened with 78+/- conifer trees, planted and maintained by the applicant. Aesthetic and/or visual impacts are limited to those traveling the road, or from looking in the direction of the array from across the road. Although 6 the project will be somewhat viewable from the road, most of the project will be hidden behind trees and vegetation along the slope of the project site. The Town of Ithaca and Tompkins County have established Scenic Resources Inventories that identify significant views in the West Hill area. Mecklenburg Road/NYS Route 79 is not a designated federal or state scenic byway, but there are many scenic viewpoints along the road, beginning just east of 1362 Mecklenburg Road, in the area of the proposed project. There are no scenic views in the project area listed in the county inventory, but there are scenic views listed in the town inventory. Views “9a” and “9b” (attached to the EAF Part 1) are noted in the Town Scenic Resource Inventory as having “gateway” views of Ithaca, Cornell University, and the hills of Dryden. However, the views are visible in directions that are downhill from the location of the solar project. The viewshed analysis provided by the applicant illustrates this, particularly in photos 4, 6, and 11. The best views along Mecklenburg Road in the Scenic Resources Inventory are seen while looking directly down the road or across the field downhill of the solar project, towards the City of Ithaca. Therefore, there are no identified scenic resources around the project site that would be impacted by the proposed development. Based on the above information, impacts identified in this section would be considered small in magnitude. 14. Impact on Energy a. The proposed action will require a new, or an upgrade to an existing, substation. Briefly describe the impact on energy: The proposed project is located along an existing electric distribution line and is in one of the few locations in the Town of Ithaca that have been identified in the newly revised Solar Law (Town Code §270-219.1) as being appropriate for large-scale solar facilities. The applicant has obtained approval from NYSEG to connect the new solar facility to the distribution grid to NYSEG’s West Hill Substation. NYSEG will install one new utility pole along Mecklenburg Road to accommodate the project. The proposed solar project will reduce the amount of electricity that needs to be moved across transmission and distribution lines, which will result in a reduction in greenhouse gas emissions. Based on the above information, impacts identified in this section would be considered small in magnitude. 15. Impact on Noise and Light a. The proposed action may produce sound above noise levels established by local regulation. f. Other impacts: The project includes lighting that must comply with the Town of Ithaca Code, Chapter 173, Outdoor Lighting. Briefly describe the impact on noise and light: The project will create noise impacts during construction of the solar array and related infrastructure. These impacts will be temporary and will cease once the project is completed. The project materials include a glint and glare study with more than 40 observation points (at the June 20, 2023, meeting, the Planning Board requested adding points 39, 40, and the points along Bundy and Mecklenburg Roads, along with modeling points with vegetation). The study concluded that the project, in its current configuration “will not produce glare that impacts any of the identified and analyzed Receptors.” 7 The project may include safety lighting associated with the equipment/battery storage units, along with a utility pole with a light. Any proposed outdoor lighting will be required to comply with the provisions of Town of Ithaca Code Chapter 173, Outdoor Lighting. The Code contains provisions related to glare and dark-sky compliancy. Based on the above information, impacts identified in this section would be considered small in magnitude. 18. Consistency with Community Character f. Proposed action is inconsistent with the character of the existing natural landscape. Briefly describe the impact on community character: The project site is a large, open farm field, surrounded by vegetation and other agricultural fields. The proposed solar array – or any other type of development on the site - would be in contrast with the character of the existing natural landscape. However, the proposed solar array will be located at least 900 feet from Mecklenburg Road and will contain a thick line of conifer trees along the frontage that will screen its view along the road. The proposed use of the site will include sheep grazing and other agricultural uses that will maintain the agricultural character of the area. These mitigations will minimize impacts on the character of the surrounding agricultural community. The project also includes a decommissioning plan that will restore the land back to agricultural use if there is (1) a lack of solar production for six continuous months, (2) a lack of a current local permit, (3) failure to maintain any required decommissioning bond or other security, and (4) a violation of any site plan conditions or permit conditions that continues more than 90 days after the town provides written notice of such violation. The decommissioning plan will ensure that the agricultural character of the property will be re-established if and when the solar use terminates. Based on the above information, impacts identified in this section would be considered small in magnitude. Staff Recommendation, Determination of Significance A negative determination of environmental significance is recommended for the action as proposed, based on review of the materials submitted for the proposed action, the information above, and analysis of the magnitude and importance of the project impacts.

THIS SPECIFICATION IS TO BE DEVELOPED FOR POST-CONSTRUCTION USE, SOIL RESTORATION PRACTICES MAY BE APPLICABLE TO RESTORE CONSTRUCTION RELATED COMPACTION TO PRE-EXISTING CONDITIONS AND SHOULD BE VERIFIED BY SOIL PENETROMETER READINGS. THE PENETROMETER READINGS SHALL BE COMPARED TO THE RESPECTIVE RECORDED READINGS TAKEN PRIOR TO CONSTRUCTION, EVERY 100 LINEAR FEET ALONG THE PROPOSED ROADWAY. 10.TO ENSURE THAT SOIL IS NOT TRACKED ONTO THE LIMITED USE PERVIOUS ACCESS ROAD, IT SHALL NOT BE USED BY CONSTRUCTION VEHICLES TRANSPORTING SOIL, FILL MATERIAL, ETC. IF THE LIMITED USE PERVIOUS ACCESS IS COMPLETED DURING INITIAL PHASES OF CONSTRUCTION, A STANDARD NEW YOK STATE STABILIZED CONSTRUCTION ACCESS SHALL BE CONSTRUCTED AND UTILIZED TO REMOVE SEDIMENT FROM CONSTRUCTION VEHICLES AND EQUIPMENT PRIOR TO ENTERING THE LIMITED USE PERVIOUS ACCESS ROAD FROM ANY LOCATION ON, OR OFF SITE. MAINTENANCE OF THE PERVIOUS ACCESS ROAD WILL BE REQUIRED IF SEDIMENT IS OBSERVED WITHIN THE CLEAN STONE. 11.THE LIMITED USE PERVIOUS ACCESS ROAD SHALL NOT BE CONSTRUCTED OR USED UNTIL ALL AREAS SUBJECT TO RUNOFF ONTO THE PERVIOUS ACCESS HAVE ACHIEVED FINAL STABILIZATION. 12.PROJECTS SHOULD AVOID INSTALLATION OF THE LIMITED USE PERVIOUS ACCESS ROAD IN POORLY DRAINED AREAS, HOWEVER IF NO ALTERNATIVE LOCATION IS AVAILABLE, THE PROJECT SHALL UTILIZE WOVEN GEOTEXTILE MATERIAL AS DETAILED IN FOLLOWING NOTES. 13.THE DRAINAGE DITCH IS OFFERED IN THE DETAIL FOR CIRCUMSTANCES WHEN CONCENTRATED FLOW COULD NOT BE AVOIDED. THE INTENTION OF THIS DESIGN IS TO MINIMIZE ALTERATIONS TO HYDROLOGY, HOWEVER WHEN DEALING WITH 5%-15% GRADES NOT PARALLEL TO THE CONTOUR, A ROADSIDE DITCH MAY BE REQUIRED. THE NYS STANDARDS AND SPECIFICATIONS FOR EROSION AND SEDIMENT CONTROLS FOR GRASSED WATERWAYS AND VEGETATED WATERWAYS ARE APPLICABLE FOR SIZING AND STABILIZATION. DIMENSIONS FOR THE GRASSED WATERWAY SPECIFICATION WOULD BE DESIGNED FOR PROJECT SPECIFIC HYDROLOGIC RUNOFF CALCULATIONS, AND A SEPARATE DETAIL FOR THE SPECIFIC GRASSED WATERWAY WOULD BE INCLUDED IN THIS PRACTICE. RUNOFF DISCHARGES WILL BE SUBJECT TO THE OUTLET REQUIREMENTS OF THE REFERENCED STANDARD. INCREASED POST-DEVELOPMENT RUNOFF FROM THE ASSOCIATED ROADSIDE DITCH MAY REQUIRE ADDITIONAL PRACTICES TO ATTENUATE RUNOFF TO PRE-DEVELOPMENT CONDITIONS. 14.IF A ROADSIDE DITCH IS NOT UTILIZED TO CAPTURE RUNOFF FROM THE ACCESS ROAD, THE PERVIOUS ACCESS ROAD WILL HAVE A WELL-ESTABLISHED PERENNIAL VEGETATIVE COVER, WHICH SHALL CONSIST OF UNIFORM VEGETATION (I.E. BUFFER), 20 FEET WIDE AND PARALLEL TO THE DOWN GRADIENT SIDE OF THE ACCESS ROAD. POST-CONSTRUCTION OPERATION AND MAINTENANCE PRACTICES WILL MAINTAIN THIS VEGETATIVE COVER TO ENSURE FINAL STABILIZATION FOR THE LIFE OF THE ACCESS ROAD. 15.THE DESIGN PROFESSIONAL MUST ACCOUNT FOR THE LIMITED USE PERVIOUS ACCESS ROAD IN THEIR SITE ASSESSMENT/HYDROLOGY ANALYSIS. IF THE HYDROLOGY ANALYSIS SHOWS THAT THE HYDROLOGY HAS BEEN ALTERED FROM PRE- TO POST-DEVELOPMENT CONDITIONS (SEE APPENDIX A OF GP-0-20-001 FOR THE DEFINITION OF “ALTER THE HYDROLOGY…”), THE DESIGN MUST INCLUDE THE NECESSARY DETENTION/RETENTION PRACTICES TO ATTENUATE THE RATES (10 AND 100 YEAR EVENTS) TO PRE-DEVELOPMENT CONDITIONS.

DATE: April 10, 2023 SUBJECT: Nexamp, Inc. Carrowmoor Solar LLC – Stormwater Management Approach Nexamp, Inc. is developing plans for the Carrowmoor Solar LLC Project: a one 5-megawatt (MWAC) solar array to be installed on a 93.65 acre parcel, located at 1340 Mecklenberg Road, Ithaca, NY(Tax ID 027.-1-15.2). Activities include the installation of the ground-mounted solar energy system consisting of tracker modules/panels, new electrical equipment, battery storage, and accessories including electrical lines, access road, and inverter/transformer equipment pads. The project proposes to follow the NYSDEC guidance from January 2020 for stormwater approach for construction of solar projects in New York State. The DEC provides two scenarios for construction of solar panels. Our design intent follows Scenario 1, with provisions included to address Note 5. Please see the breakdown below of how this project site will comply with Scenario 1 and Note 5: Scenario 1: The DOW considers solar panel projects designed and constructed in accordance with the following criteria to be a “Land clearing and grading for the purposes of creating vegetated open space (i.e. recreational parks, lawns, meadows, fields)” type project as listed in Table 1, Appendix B of the CGP. Therefore the SWPPP for this type of project will typically just need to address erosion and sediment controls. 1. Solar panels are constructed on post or rack systems and elevated off the ground surface, Solar panels will be constructed on an elevated racking system. 2. The panels are spaced apart so that rain water can flow off the down gradient side of the panel and continue as sheet flow across the ground surface*, Racked panels are spaced such that the row spacing in between panels (front-edge to back- edge) is equal to or greater than the width of the panels in accordance with the Maryland Guidance. 3. For solar panels constructed on slopes the individual rows of solar panels are generally installed along the contour so rain water sheet flows down slope*, 2 The site generally slopes Southwest to Northeast, with many parts of the site sloping predominately West to East. This array utilizes a tracker system, with panel rows oriented in a North-South fashion, and generally along the contours. 4. The ground surface below the panels consist of a well-established vegetative cover (see “Final Stabilization” definition in Appendix A of the CGP) Final ground cover will consist of a seeded, vegetative meadow and grass coverage to CGP Final Stabilization requirements. 5. The project does not include the construction of any traditional impervious area (i.e. buildings, substation pads, gravel access roads or parking areas, etc.) See response under NYSDEC Notes for Item 5 below. 6. Construction of the solar panels will not alter the hydrology from pre-to post development conditions (see Appendix A of the CGP, for definition of “Alter the hydrology…”). Note: The design professional shall perform the necessary site assessment/hydrology analysis to make this determination. The design intent is to preserve the original hydrology patterns. A HydroCAD assessment showing no increase or major alteration to hydrologic patterns from pre-to post development will be provided as part of the full SWPPP report. *Refer to Maryland’s “Stormwater Design Guidance- Solar Panel Installations” attached for guidance on panel installation. **See notes below for additional criteria. **Notes - Item 1: For solar panel projects where the panels are mounted directly to the ground (i.e. no space below panel to allow for infiltration of runoff), the SWPPP must address post- construction stormwater management controls designed in accordance with the sizing criteria in Chapter 4 of the NYS Stormwater Management Design Manual, dated January 2015 (Note: Chapter 10 for projects in NYC EOH Watershed). Not Applicable. - Item 5: For solar panel projects that include the construction of traditional impervious areas (i.e. buildings, substation pads, gravel access roads or parking areas, etc.), the SWPPP must address post-construction stormwater management controls for those areas of the project. This applies to both Scenario 1 and 2 above. 3 The project also contains 4 equipment/battery storage pads, and gravel access roads for the solar array and the interconnection utility poles. These impervious features will be treated with vegetated filter strips per the NYSDEC Stormwater Design Manual requirements. The use of filter strips for treatment on this project limits grading and installation of pipes and filter media and preserves natural sheet flow conditions to the highest extent possible. The NYSDEC memo refers to the Maryland “Stormwater Design Guidance – Solar Panel Installations” for additional design guidance. The Maryland guidance provides additional context for sheet flow disconnection, including suitable slope ranges and recommendations to limit earthwork and construction traffic. Through our years of experience designing and permitting solar projects in NY State, we have worked with various DEC regions and MS4s to apply the Maryland Guidance in reasonable, functional fashions on projects. Below are design criteria currently accepted by NYSDEC Region 8 for solar installation on slopes in excess of 5% but less than 10% that LaBella has frequently used as a basis of our stormwater approach and design on solar projects: In the NYSDEC Region 8, we are currently willing to accept the following design criteria in regard to solar panel installations: 1. On 5-10% slopes it is our experience that solar panel projects with the panels arranged as shown in the attached photos, including a 1” gap between panels, will avoid creating concentrated flow paths on a well vegetated site. In such cases, flow diffusers, or other dripline features are not required as suggested in the Maryland Solar Guidance. However, if the topography of the slope is such that it concentrates flows coming off the panels, other erosion controls may be necessary. Additionally, temporary stabilization will be needed on erosive soils until a dense vegetated cover can be established. 2. On slopes 10% or greater, additional controls are required. These can take the form of water bars or level spreaders. We are not recommending that water bars be used as level spreaders. For both practices they should be implemented across the slope at the recommended frequency as indicated in the Blue Book detail for water bars. That is every 75’ for slopes between 10% and 20%. In all instances, if erosion is observed to be occurring despite implementation of planned erosion and sediment controls, additional measures should be considered and implemented to minimize soil erosion and offsite transport. The entirety of the solar array footprint resides in areas with slopes 10% or less, with the vast majority of the array footprint located in areas with slopes 5% or less. The solar panel rows consist of varying lengths of racks with two modules in a portrait configuration. All multi-module solar racking configurations incorporate gaps (on average 1”) in between modules to account for thermal shrink/swell throughout the course of the year. In addition to this, since the solar panels will be installed on a tracker system, the exact location of the water dripline from the 4 panels to the ground will vary throughout the course of the day, lessening the frequency and concentration of flow a single point would receive from the solar panels at the dripline. Attached to this memo, please find the NYSDEC Stormwater Guidance, as well as our Region 8 correspondence regarding implementation of the Maryland Guidance on solar projects. M E M O R A N D U M TO: Regional Water Engineers FROM: Robert Wither, Chief, South Permit Section SUBJECT: Solar Panel Construction Stormwater Permitting/SWPPP Guidance DATE: January 17, 2020 Issue The Department is seeing an increase in the number of solar panel construction projects across New York State. This has resulted in an increase in the number of questions on Construction General Permit (CGP) and Stormwater Pollution Prevention Plan (SWPPP) requirements from design professionals because the current CGP (GP- 0-15-002) does not include a specific reference to the SWPPP requirements for solar panel projects in Tables 1 and 2 of Appendix B. To address this issue, the Division of Water (DOW) has developed the following guidance on CGP/SWPPP requirements for the different types of solar panel projects. Scenario 1 The DOW considers solar panel projects designed and constructed in accordance with the following criteria to be a “Land clearing and grading for the purposes of creating vegetated open space (i.e. recreational parks, lawns, meadows, fields)” type project as listed in Table 1, Appendix B of the CGP. Therefore, the SWPPP for this type of project will typically just need to address erosion and sediment controls. 1. Solar panels are constructed on post or rack systems and elevated off the ground surface, 2. The panels are spaced apart so that rain water can flow off the down gradient side of the panel and continue as sheet flow across the ground surface*, 3. For solar panels constructed on slopes, the individual rows of solar panels are generally installed along the contour so rain water sheet flows down slope*, 4. The ground surface below the panels consist of a well-established vegetative cover (see “Final Stabilization” definition in Appendix A of the CGP), 5. The project does not include the construction of any traditional impervious areas (i.e. buildings, substation pads, gravel access roads or parking areas, etc.), 6. Construction of the solar panels will not alter the hydrology from pre-to post development conditions (see Appendix A of the CGP, for definition of “Alter the hydrology…”). Note: The design professional shall perform the necessary site assessment/hydrology analysis to make this determination. *Refer to Maryland’s “Stormwater Design Guidance- Solar Panel Installations” attached for guidance on panel installation. **See notes below for additional criteria. Scenario 2 If the design and construction of the solar panels meets all the criteria above, except for item 6, the project will fall under the “All other construction activities that include the construction or reconstruction of impervious area or alter the hydrology from pre-to post development conditions, and are not listed in Table 1” project type as listed in Table 2, Appendix B of the CGP. Therefore, the SWPPP for this type of project must address post-construction stormwater practices designed in accordance with the sizing criteria in Chapter 4 of the NYS Stormwater Management Design Manual, dated January 2015 (Note: Chapter 10 for projects in NYC EOH Watershed). The Water Quality Volume (WQv)/Runoff Reduction Volume (RRv) sizing criteria can be addressed by designing and constructing the solar panels in accordance with the criteria in items 1 – 4 above, however, the quantity control sizing criteria (Cpv, Qp and Qf) from Chapter 4 (or 10) of the Design Manual must still be addressed, unless one of the waiver criteria from Chapter 4 can be applied. **See notes below for additional criteria. ** Notes - Item 1: For solar panel projects where the panels are mounted directly to the ground (i.e. no space below panel to allow for infiltration of runoff), the SWPPP must address post-construction stormwater management controls designed in accordance with the sizing criteria in Chapter 4 of the NYS Stormwater Management Design Manual, dated January 2015 (Note: Chapter 10 for projects in NYC EOH Watershed). - Item 5: For solar panel projects that include the construction of traditional impervious areas (i.e. buildings, substation pads, gravel access roads or parking areas, etc.), the SWPPP must address post-construction stormwater management controls for those areas of the project. This applies to both Scenario 1 and 2 above. cc: Carol Lamb-Lafay, BWP Dave Gasper, BWP Page 1 Maryland Department of the Environment Stormwater Design Guidance – Solar Panel Installations Revisions to Maryland’s stormwater management regulations in 2010 require that environmental site design (ESD) be used to the maximum extent practicable (MEP) to mimic natural hydrology, reduce runoff to reflect forested wooded conditions, and minimize the impact of land development on water resources. This applies to any residential, commercial, industrial, or institutional development where more than 5,000 square feet of land area is disturbed. Consequently, stormwater management must be addressed even when permeable features like solar panel installations exceed 5,000 square feet of land disturbance. Depending on local soil conditions and proposed imperviousness, the amount of rainfall that stormwater requirements are based on varies from 1.0 to 2.6 inches. However, addressing stormwater management does not mean that structural or micro-scale practices must be constructed to capture and treat large volumes of runoff. Using nonstructural techniques like disconnecting impervious cover reduces runoff by promoting overland filtering and infiltration. Commonly used with smaller or narrower impervious areas like driveways or open roads, the Disconnection of Non-Rooftop Runoff technique (see pp. 5.61 to 5.65 of the 2000 Maryland Stormwater Design Manual1) is a low cost alternative for treating runoff in situations like rows of solar panels. When non-rooftop disconnection is used to treat runoff, the following factors should be considered: • The vegetated area receiving runoff must be equal to or greater in length than the disconnected surface (e.g., width of the row of solar panels) • Runoff must sheet flow onto and across vegetated areas to maintain the disconnection • Disconnections should be located on gradual slopes (≤ 5%) to maintain sheetflow. Level spreaders, terraces, or berms may be used to maintain sheetflow conditions if the average slope is steeper than 5%. However, installations on slopes greater than 10% will require an engineered plan that ensures adequate treatment and the safe and non-erosive conveyance of runoff to the property line or downstream stormwater management practice. • Disconnecting impervious surfaces works best in undisturbed soils. To minimize disturbance and compaction, construction vehicles and equipment should avoid areas used for disconnection during installation of the solar panels. • Groundcover vegetation must be maintained in good condition in those areas receiving disconnected runoff. Typically this maintenance is no different than other lawn or landscaped areas. However, areas receiving runoff should be protected (e.g., planting shrubs or trees along the perimeter) from future compaction. Depending on the layout and number of panels installed, the disconnection of non-rooftop runoff technique may address some or all of the stormwater management requirements for an individual project. Where the imperviousness is high or there is other infrastructure (e.g., access roads, transformers), additional runoff may need to be treated. In these situations, other ESD techniques or micro-scale practices may be needed to provide stormwater management for these features. Example 1 – Using Non-Rooftop Disconnection Where the Average Slope ≤ 5% Several rows of solar panels will be installed in an existing meadow. The soils within the meadow are hydrologic soil group (HSG) B and the average slope does not exceed 5%. Each row of panels is 10 feet wide and the distance between rows is 20 feet. The rows of solar panels will be installed according to Figure 1 below. In this scenario, the disconnection length is the same as the distance between rows (20 feet) and is greater than the width of each row (10 feet). Therefore, each row of panels is adequately disconnected and the runoff from 1.0 inch of rainfall is treated. Figure 1. Typical Installation - Slope ≤ 5% Example 2 – Using Non-Rooftop Disconnection Where the Average Slope ≥ 5% but ≤ 10% Several rows of solar panels will be installed in an existing meadow. The soils within the meadow are hydrologic soil group (HSG) B and the average slope is greater than 5% but less than 10%. Each row of panels is 10 feet wide and the distance between rows is 20 feet. The rows of solar panels will be installed as shown in Figure 2 below. The disconnection length is the same as the distance between rows (20 feet) and is greater than the width of each row (10 feet). However, in this example, a level spreader (typically 1 to 2-foot wide and 1 foot deep) has been located at the drip edge of each row of panels to dissipate energy and maintain sheetflow. Discussion To meet State and local stormwater management requirements, ESD must be used to the MEP to reduce runoff to reflect forested conditions. While all reasonable options for implementing ESD must be investigated, minimally, the runoff from 1 inch of rainfall must be treated. In each of the examples above, there may be additional opportunities to implement ESD techniques or practices and reduce runoff that should be explored. However, simply disconnecting the runoff from the solar panel arrays captures and treats the runoff from 1.0 inch of rainfall. Where imperviousness is low and soil conditions less optimal (e.g., HSG C or D), this may be sufficient to completely address stormwater management requirements. In more dense applications or in sandy soils, additional stormwater management may be required. Page 2 Conclusion The primary purpose of Maryland’s stormwater management program is to mimic natural hydrologic runoff characteristics and minimize the impact of land development on water resources. Any land development project that exceeds 5,000 square feet of disturbance, including solar panel projects, must address stormwater management. However, for solar panels, stormwater management may be provided in a cost-effective manner by disconnecting each row of panels and directing runoff over the vegetated areas between the individual rows.

For point 2 we don't recommend trying to use water bars as level spreaders, use either or. More formally: In the NYSDEC Region 8, we are currently willing to accept the following design criteria in regard to solar panel installations: 1. On 5-10% slopes it is our experience that solar panel projects with the panels arranged as shown in the attached photos, including a 1" gap between panels, will avoid creating concentrated flow paths on a well vegetated site. In such cases, flow diffusers, or other dripline features are not required as suggested in the Maryland Solar Guidance. However, if the topography of the slope is such that it concentrates flows coming off the panels, other erosion controls may be necessary. Additionally, temporary stabilization will be needed on erosive soils until a dense vegetated cover can be established. 2. On slopes 10% or greater, additional controls are required. These can take the form of water bars or level spreaders. We are not recommending that water bars be used as level spreaders. For both practices they should be implemented across the slope at the recommended frequency as indicated in the Blue Book detail for water bars. That is every 75' for slopes between 10 and 20%. In all instances, if erosion is observed to be occurring despite implementation of planned erosion and sediment controls, additional measures should be considered and implemented to minimize soil erosion and offsite transport. Regards, Luke From: Gasic, Drazen <DGasic@LaBellaPC.com> Sent: Thursday, December 17, 2020 5:05 PM To: Scannell, Luke W (DEC) <luke.scannell@dec.ny.gov> Subject: NYSDEC Solar Guidance ATTENTION: This email came from an external source. Do not open attachments or click on links from unknown senders or unexpected emails. 2 Luke, Could you confirm my understanding below based on our solar discussion, as potential additional guidance that may be accepted if we coordinated with the regional DEC official? We are looking to make a submission to MS4s as well, and at the time, we may request that we have a conference call about the proposed design with the MS4 and the regional DEC official. Update 1: If the developer is able to provide a min. 1-inch space between the modules horizontally, then the DEC would be willing to consider not requiring flow diffusers for slopes between 5-10%. The rationale for this is that having the gap breaks up the potential accumulated sheet flow created on the modules. The DEC is also in favor of the modules being in landscape over portrait as that again reduces the surface sheet flow on the modules. Update 2: If we need to place modules in slopes greater than 10%, the DEC is willing to review calculations for water bars that are sized and designed based on the NYS Erosion Control Book (Blue Book) with the attached clarification. . The intention is to make the water bar parallel to the contour with as close to 0% cross slope, and allow water to transition from shallow concentrated flow, from solar panels, to sheet flow.

This SWPPP must be executed and permit coverage must be obtained prior to the commencement of construction activity. This SWPPP has been developed in accordance with the “New York State Department of Environmental Conservation (NYSDEC) State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Construction Activity,” Permit No. GP-0-20-001, effective January 29, 2020 through January 28, 2025. The SWPPP and accompanying plans identify and detail stormwater management, pollution prevention, and erosion and sediment control measures necessary during and following completion of construction. This SWPPP and the accompanying plans entitled “Carrowmoor Plan Set” have been submitted as a set. These engineering drawings are considered an integral part of this SWPPP. Therefore, this SWPPP is not considered complete without them. References made herein to “the plans” or to a specific “sheet” refer to these drawings. This report considers the impacts associated with the intended development with the purpose of: 1. Maintaining existing drainage patterns as much as possible while continuing the conveyance of upland watershed runoff; 2. Controlling increases in the rate of stormwater runoff resulting from the proposed development so as not to adversely alter downstream conditions; and 3. Mitigating potential stormwater quality impacts and preventing soil erosion and sedimentation resulting from stormwater runoff generated both during and after construction. The analysis and design completed and documented in this report is intended to be part of the application made for a solar development project completed on behalf of the Owner/Operator. This Master Stormwater Pollution Prevention Plan (SWPPP) has been prepared to support the state environmental quality review (SEQR) of the proposed project. The intent of this Master SWPPP is to provide sufficient documentation for an overall SEQR determination, and to serve as the baseline for the final SWPPP that will be prepared for the proposed development, as approved. As such, design concepts are provided for stormwater collection and conveyance systems, and water quality and quantity control facilities. This report is not intended to be a final engineering document as certain detailed aspects of the project are likely to change during the site plan review process. Portions of the design were advanced to substantiate regulatory compliance determinations and to provide input pertinent to the environmental assessment of impacts of the proposed project. Final stormwater practice designs will be advanced in support of and during the site plan permitting process. The methodology used to develop this Master SWPPP shall be adhered to for the preparation of the project’s final SWPPP. Stormwater quality and quantity controls designed for this Master SWPPP are preliminary in nature and are intended to demonstrate their location, approximate size, and design concept. Detailed analysis of these practices must be performed, and their design refined as part of the final SWPPP. Stormwater Pollution Prevention Plan 2230713 Page 2 The stormwater analysis identified herein follows the “NYS Stormwater Management Design Manual,” dated January 2015 (Design Manual) and the USDA Technical Release No. 20. This Master SWPPP and analysis are an integral part of the project’s natural resource management plan which takes into consideration existing parameters of site topography, soils, erosion potential, surface waters, their connectivity and water quality of receiving water bodies. Stormwater mitigation measures primarily involve preventing soil erosion and sedimentation resulting from stormwater run-off during and after construction. During construction, this is accomplished by sequencing site disturbance activities to establish erosion controls, minimize disturbed areas, maintain existing vegetation as much as possible, and stabilize newly disturbed areas as soon as possible. Stormwater pollutant controls utilized during construction will include temporary sediment barriers and sediment traps designed in accordance with the “NYS Standards and Specifications for Erosion and Sediment Control”. Stormwater pollutant controls utilized after construction will include stormwater quality control practices designed in accordance with the Manual. Land development can also have an effect on site hydrology. Impervious areas such as rooftops, roads, driveways, and parking lots can cause rainfall to rapidly convert into stormwater runoff. Increases in runoff can cause stream bank erosion and floodplain expansion. To mitigate these impacts, stormwater quantity controls will be implemented to capture and release run-off at less than pre-development discharge rates. A hydrologic and hydraulic analysis was/will be performed using computer modeling and an evaluation of the proposed improvements across the project site. 1.1 Project Description Nexamp is proposing a development project, to include: the installation of a 5-mW solar array, electrical poles, fencing, underground electrical trenching, and an access road. The project will disturb greater than 1-acre of land. A 5 acre waiver is being requested for this project. A Site Location Map has been provided in Appendix A, as Figure A-1. This type of project is included in Table 2 of Appendix B of GP-0-20-001; and the project site is not located in one of the watersheds listed in Appendix C of GP-0-20-001. Therefore, this SWPPP includes post-construction stormwater management practices, as well as erosion and sediment controls. This project is not located within a regulated, traditional land use control Municipal Separate Stormwater Sewer System (MS4). Runoff from the project site will discharge to the Williams Brook and Linderman Creek, which are not included in the list of Section 303(d) water bodies included in Appendix E of GP-0-20-001. Project construction activities will consist primarily of site grading, paving, and the installation of storm drainage and public utility infrastructure necessary to support the proposed development project. Construction phase pollutant sources anticipated at the site are disturbed (exposed) soil, vehicle fuels and lubricants, chemicals associated with building construction, and building materials. Without adequate control there is the potential for each type of pollutant to be transported by stormwater. 1.2 Stormwater Pollution Controls The stormwater pollution controls outlined herein have been designed and evaluated in accordance with the following standards and guidelines: • New York State Stormwater Management Design Manual, dated January 2015 (Design Manual). Stormwater Pollution Prevention Plan 2230713 Page 3 • New York State Standards and Specifications for Erosion and Sediment Control, dated November 2016 (SSESC). • Town of Ithaca Stormwater Management and Erosion and Sediment Control Stormwater quality will be enhanced through the implementation of temporary and permanent erosion and sediment control measures, vegetated filter strips, and other construction-phase pollution controls outlined herein. The proposed stormwater management approach consisting of on-site stormwater management practices will adequately collect, treat, and convey the stormwater runoff. Vegetated filter strips will be used to manage stormwater runoff generated by the proposed development project. Pre- and post-development surface runoff rates have been evaluated for the 1-, 10-, and 100-year 24- hour storm events. Comparison of pre- and post-development watershed conditions demonstrates that the peak rate of runoff from the project site will not be increased. The post-construction stormwater management practice(s) will be owned by Nexamp. Policy and procedures will be in place, which ensure operation and maintenance of the practice(s) in accordance with the operation and maintenance plan. 2.0 SITE CHARACTERISTICS 2.1 Land Use and Topography The project site is located within the AG Agriculture zoning district. A 5-mW solar array is subject to a special use permit within this district. The overall site is slightly sloping, with slopes ranging from 2 to 12 percent. Site elevations range from approximately 1074 feet above mean sea level (MSL) to 1128 feet MSL. The site is generally sloped from west to east, with the highest elevations in the southwestern corner of the project site. The northern portion of the site slopes towards the northeast and the southern portion of the site slopes to the southeast. 2.2 Soils and Groundwater The US Department of Agriculture (USDA) Web Soil Survey (http://websoilsurvey.nrcs.usda.gov/app/) was used to obtain surficial soil conditions for the study area, as follows: Table 1: USDA Soil Data Map Symbol & Description Hydrologic Soil Group Permeability (inches/hour) Erosion Factor K Depth to Water Table (feet) Depth to Bedrock (feet) BgC – Bath and Valois soils, 5 to 15 percent slopes C <0.2 0.20 2-3 2-3 EbB – Erie channery silt loam, 3 to 8 percent slopes D <0.14 0.24 0.5 – 1.2 <2 Decommissioning Plan – Carrowmoor Solar August 3rd, 2023 Carrowmoor Solar, LLC (The Company), has prepared this Decommissioning Plan (Plan) for its proposed solar photovoltaic facility to be constructed on private property located at Mecklenburg Rd, Ithaca, NY, tax map number 27-1-15.2. The parcel is .36 miles west of Westhaven Rd and 1.2 mi East of Sheffield Rd. The Plan describes the process for decommissioning the Facility in accordance with state and local requirements. Facility Description The Facility will consist of a 5,000-kilowatt (or 5 megawatts, MW) alternating current (AC) capacity solar power-generating array secured within a chain-link fence surrounding the solar panels and equipment, accessed through a locked gate located inside the property. Each Facility will include the following site features: • PV Modules, inverter(s), and transformer (filled with biodegradable mineral oil) • Combiner boxes and switchgear • Battery storage • Concrete pad(s) • Screw or driven piles and racking to support the PV modules • DC and AC wiring and conduit • A gravel access drive • Stormwater management features including swales • Landscaping • Exterior 7-foot agricultural fencing • A metal security gate at the entrance to the array area • Overhead utility lines and poles Stakeholders Role Contact Information Carrowmoor Solar, LLC System Owner Attn: Carrowmoor Solar 101 Summer St, Flr 2 Boston, MA 02110 Phone: 617.431.1440 Email: Legal@Nexamp.com Town of Ithaca – Codes Office Town Code Enforcement and Site Inspection Town of Ithaca Codes Office 215 N Tioga St Ithaca, NY 14850 Phone: 1 607 273 1721 Town of Ithaca – Planning Board Site Plan Jurisdiction Town of Ithaca Planning Board Chair 215 N Tioga St Ithaca, NY 14850 Phone: 1 607 273 1721 Town of Ithaca – Town Board Decommissioning Bond Holder Town Board 215 N Tioga St Ithaca, NY 14850 Phone: 1 607 273 1721 NYSEG Utility Operator Distributed Generation Office 18 Link Drive Binghamton, NY Rancich Family LTD Partnership Landowner PO BOX 547, Ithaca, NY 14851-0547 All listed stakeholders will receive a copy of the decommissioning plan when executed, and will receive revised copies when revisions are made. All subsequent changes to the Decommissioning Plan will need to be approved by the Town Board, and recorded with the County Clerk upon execution. Expected Lifetime Carrowmoor Solar, LLC has a land lease agreement with the owner of the parcel in question for upwards of 40 years, and has permission to operate the system during that time. Panels are warrantied for 25 years, and the Company anticipates the replacement of inverters with equivalent models as necessary. The project is expected to operate for a bare minimum of 25 years, but is expected to operate for the full term of its lease with the landowner. Triggers and Notices Decommissioning plan will be implemented if the following circumstances occur, per guidance in the Town of Ithaca Local Law §270-219.1-C(4)(i)(i) • lack of production for six continuous months (or for 12 of any 18 months); • lack of a current local permit; • failure to maintain any required decommissioning bond or other security; and • a violation of any site plan conditions or permit conditions that continues more than 90 days after the Town provides written notice of such violation. Every effort will be made to adhere to the decommissioning event criteria outlined above. However, the asset owner will have an opportunity for appeal for extension of the abandonment timeline with adequate proof that the delay can be attributed to supply chain, permitting, or labor issues outside of the owner’s complete control. Prior to the decommissioning plan execution, the asset owner will transmit an electronic notice followed by a hard copy letter to the Town Clerk and/or Code Enforcement Office in the event of any decommissioning, sale, transfer, or any event that may result in partial or complete decommissioning of the site. Notices will be delivered to the addresses below; Town of Ithaca Code Enforcement Office Email: codes@town.ithaca.ny.us 215 North Tioga St Ithaca, NY 14850 Decommissioning Plan The Facility will be decommissioned by completing the following major steps: Dismantlement, Demolition, and Disposal or Recycle; and Site Stabilization, as further described below. In addition to the tasks outlined below, Carrowmoor Solar agrees that all Decommissioning obligations will be done in accordance with the Town of Ithaca’s Zoning Law, Local Law 10, 2023, Section 6; Construction Standards, hereto attached at Exhibit A to this agreement, and NYS Department of Agriculture and Markets (NYSDAM) Guidelines, as set forth in the NYSDAM Guidelines for Agricultural Mitigation for Solar Energy Projects (Revised October 18th, 2019), Hereto attached as Exhibit B to this agreement. Carrowmoor Solar has the sole responsibility to remove the system per the terms of this agreement, and the terms of its lease agreement with the Rancich Family Limited Partnership. Should Carrowmoor Solar be sold or transferred, all Decommissioning responsibilities will transfer to the owning entity. Should Carrowmoor Solar fail to complete its decommissioning obligations, a surety will be provided to the Town to pay for the costs associated with Decommissioning the system. Decommissioning timeline is anticipated to be about six months (180 days) and will be weather dependent, with extensions resulting due to the time of year and overall weather conditions as to not adversely affect the land or provide unsafe working conditions for site employees. Soil Decompaction and stabilization may prolong the decommissioning process due to seasonality of these activities and the need to protect soil from erosion. Dismantlement, Demolition, and Disposal or Recycle A significant portion of the components that comprise each Facility will include recyclable or re-saleable components, including copper, aluminum, galvanized steel, and modules. Due to their re-sale monetary value, these components will be dismantled, disassembled, and recycled rather than being demolished and disposed of. Typically, salvage value is taken into account when estimating net decommissioning costs. Nexamp has proceeded to omit those costs to alleviate concerns about recycling availability and market instability. Following coordination with NYSEG (“Utility”) regarding timing and required procedures for disconnecting each Facility from the utility distribution network, all electrical connections to the system will be disconnected and all connections will be tested locally to confirm that no electric current is running through them before proceeding. All electrical connections to the PV modules will be severed at each module, and the modules will then be removed from their framework by cutting or dismantling the connections to the supports. Modules will be removed and sold to a purchaser or recycler. In the event of a total fracture of any modules, the interior materials are silicon-based and are not hazardous. Disposal of these materials at a landfill will be permissible. The PV mounting system framework will be dismantled and recycled. The metal piles will be removed and recycled. All other associated structures will be demolished and removed from the site for recycling or disposal. This will include the site fence and gates, which will likely be reclaimed or recycled. Grade slabs will be broken and removed to a depth of four feet below grade, and clean concrete will be crushed and disposed of off-site or recycled (reused either on- or off- site). The portion of the gravel access road created specifically for the project, will be removed as well. Aboveground utility poles owned by Carrowmoor Solar, LLC will be completely removed and disposed of off-site in accordance with utility best practices. Any overhead wires will be removed from each Facility and will terminate at the utility-owned connections inside the property. Underground wires buried less than 4’ deep will be removed per Town of Ithaca regulations(§270-219.1-C(4)(i)(v).Stock The access road will remain in place to the final utility-owned electrical poles and the Utility will be responsible for dismantling those overhead wires and poles under its ownership. Coordination with The Utility, personnel will be conducted to facilitate removal of any poles and overhead wires located on the site. A final site walkthrough will be conducted to remove debris and/or trash generated during the decommissioning process, and will include removal and proper disposal of any debris that may have been wind-blown to areas outside the immediate footprint of each Facility being removed. All solid and/or hazardous waste will be disposed of in accordance with local, state, and federal regulations. Should the Town have reason to suspect the contamination of soils on the property, following confirmation of said contamination by third party contractor, soils will be removed and disposed of in accordance with local, state and federal regulations. Road Removal All access road materials will be removed, and graded areas will be returned to grade using unless otherwise specified by the landowner. Re-graded area will be seeded and stabilized immediately upon completion. Stormwater Feature Removal All stormwater features will be removed and regraded. Where appropriate, vegetation will be removed and all stormwater features will be filled. Re-graded area will be seeded and stabilized immediately upon completion. Screening Removal Removal of screening will be conditional based on Town feedback at the time of Building Permit Review. Without explicit town approval, all vegetative screening features will remain on site following decommissioning. Should removal be mandated, screening will be disposed of offsite in an appropriate manner. Where appropriate and necessary, soil depressions will be filled. Re-graded area will be seeded and stabilized immediately upon completion. Soil Management and Site Stabilization It is anticipated that the removal of the facility will cause disturbance of rmore than 5 acres, and will thus be subect to a SPDES permit and SWPPP. Erosion control measures will be designed and established with the Town at the time of Building Permit issuance. Per Town regulations, all agricultural areas shall be decompacted to a depth of 18” following removal of materials from the site. Rocks and large aggregate will be removed from site and topsoil replaced. The areas of each Facility that are disturbed during decommissioning will be re-graded to establish a uniform slope and stabilized via hydroseeding with a ground treatment approved by the Building Inspector. Environmental Monitoring Given the Project’s limits of disturbance is anticipated to be less than 50 acres, an environmental monitor is not required according to NYSDAM guidelines. Per the Town of Ithaca’s local law, a monitor would be required if prime soils existed on site, but as this is not the case we do not anticipate a local requirement for this oversight during active decommissioning. Instead, the asset owner will coordinate with the Town to hire a qualified environmental monitor who will consult on the restoration, and post-construction monitoring for no less than two years. Inspections shall take place in spring, summer and fall per Town Regulations. Permitting Requirements Given the size and location of each Facility, several approvals will be obtained prior to initiation of the decommissioning process. Table 1 provides a summary of the expected approvals if the decommissioning were to take place in April 2023. Noting that the decommissioning is expected to occur at a much later date, the permitting requirements listed in the table below will be reviewed at that time and updated based on then current local, state, and federal regulations.

Current Permitting Requirements for Decommissioning Permit Agency Threshold/Trigger State Pollutant Discharge Elimination System (SPDES) General Permit for Discharges from Construction Activity New York State Department of Environmental Conservation (NYSDEC) Ground disturbance of greater than 1 acre with discharge to wetlands or water bodies. Requires preparation of a Stormwater Pollution Prevention Plan, including erosion and sedimentation controls. Building Permit Town Building Department A building permit must be obtained for any construction, alteration, repair, demolition, or change to the use or occupancy of a building. Decommissioning Surety Proposal – Carrowmoor Solar August 3rd, 2023 Consistent with the approach it has taken in other communities, Carrowmoor Solar, LLC, offers to provide a decommissioning surety bond, to be posted prior at the commercial operation date, in the amount of $499,875.00, for decommissioning of the solar and BESS systems in the unlikely event that the company is unable to meet its contractual obligations for solar project removal and restoration. The decommissioning bond, of which Carrowmoor Solar will serve as the principal and the Town of Ithaca shall serve as the as the obligee, starting at the commercial operation date, shall remain in place for the life of the system and for 18 months following the removal of the system. The Town shall have the right to draw on this bond should it be made aware that the system has not produced energy and conveyed it to the electric grid for any 12 consecutive months. Upon drawing on the balance of the bond, the Town assumes responsibility for the decommissioning of the system. In developing the decommissioning surety bond, the company utilized recent decommissioning costs estimate from similar Community Solar and storage projects. The estimation leading to this rate is attached to this proposal as Exhibit B. These costs have been affirmed by our engineering partners at LaBella Associates. A memorandum documenting their diligence has been attached to this plan as Exhibit C. This bond will be reviewed every three years until which time the company’s decommissioning obligations have been fulfilled. Carrowmoor Solar agrees to submit revised removal cost estimates to the Town and the bond company on three-year intervals. Posted bonds will reflect this estimate for the next three years, until which time the costs of removal are reassessed. The bond’s start date shall be the first month following the commercial operation date of the facility. The bond has no set term, and will remain in place for until 18 months following system removal.

These guidelines apply to project areas subject to ground disturbance 1 within agricultural lands including: • Lands where agriculture use will continue or resume following the completion of construction (typically those lands outside of the developed project’s security fence); • Lands where the proposed solar development will be returning to agricultural use upon decommissioning, (typically those lands inside of the developed project’s security fence); • Applicable Area under review pursuant to Public Service Law Article 10 Siting of Major Electric Facilities. The Project Company will incorporate these Guidelines into the development plans and applications for permitting and approval for solar projects that impact agricultural lands. If the Environmental Monitor, hereafter referred to as EM, determines that there is any conflict between these Guidelines and the requirements for project construction that arise out of the project permitting process, the Project Company and its EM, will notify the New York State Department of Agriculture and Markets (NYSDAM), Division of Land and Water Resources, and seek a reasonable alternative. Environmental Monitor (EM) The Project Company (or its contractor) shall hire or designate an EM to oversee the construction, restoration and follow-up monitoring in agricultural areas. The EM shall be an individual with a confident understanding of normal agriculture practices 2 (such as cultivation, crop rotation, nutrient management, drainage (subsurface and/or surface), chemical application, agricultural equipment operation, fencing, soils, plant identification, etc.) and able to identify how the project may affect the site and the applicable agricultural practices. The EM should also have experience with or understanding of the use of a soil penetrometer for compaction testing and record keeping. The EM may serve dual inspection roles associated with other Project permits and/or construction duties, if the agricultural workload allows. The EM should be available to provide site-specific agricultural information as necessary for project development through field review and direct contact with both the affected farm operators and NYSDAM. The EM should maintain regular contact with appropriate onsite project construction supervision and inspectors throughout the construction phase. The EM should maintain regular contact with the affected farm operator(s) concerning agricultural land impacted, management matters pertinent to the agricultural operations and the site-specific implementation of agricultural resource mitigation measures. The EM will serve as the agricultural point of contact. 1Ground Disturbance is defined as an activity that contributes to measurable soil compaction, alters the soil profile or removes vegetative cover. Construction activities that utilize low ground pressure vehicles that do not result in a visible rut that alters soil compaction, is not considered a Ground Disturbance. Soil compaction should be tested using an appropriate soil penetrometer or other soil compaction measuring device. The soil compaction test results within the affected area will be compared with those of the adjacent unaffected portion of the agricultural area. 2 An EM is not expected to have knowledge regarding all of the listed agricultural practices, but rather a general understanding such that the EM is able to perform the EM function. DocuSign Envelope ID: A6F92C15-A20B-4802-8FFC-066B8543F286 2 Solar Guidelines (Rev. 10/18/2019) NYSDAM 1. For projects involving less than 50 acres of agricultural land within the limits of disturbance (LOD),3 the EM shall be available for consultation and/or on-site whenever construction or restoration work that causes Ground Disturbance is occurring on agricultural land. 2. For projects involving 50 acres or more of agricultural land within the (LOD) (including projects involving the same parent company whether phased or contiguous projects), the EM shall be on site whenever construction or restoration work requiring or involving Ground Disturbance is occurring on agricultural land and shall notify NYSDAM of Project activity. The purpose of the agency coordination would be to assure that the mitigation measures of these guidelines are being met to the fullest extent practicable. The Project Company and the NYSDAM will agree to schedule inspections in a manner that avoids delay in the work. NYSDAM requires the opportunity to review and will approve the proposed EM based on qualifications or capacities. Construction Requirements • Before any topsoil is stripped, representative soil samples should be obtained from the areas to be disturbed. The soil sampling should be consistent with Cornell University’s soil testing guidelines, and samples should be submitted to a laboratory for testing PH, percent organic material, cation exchange capacity, Phosphorus/Phosphate (P), and Potassium/Potash (K). The results are to establish a benchmark that the soil’s PH, Nitrogen (N), Phosphorus/Phosphate (P), and Potassium/Potash (K) are to be measured against upon restoration. If soil sampling is not performed, fertilizer and lime application recommendations for disturbed areas can be found at https://www.agriculture.ny.gov/ap/agservices/Fertilizer_Lime_and_Seeding_Recommendations.pdf . • Stripped topsoil should be stockpiled from work areas (e.g. parking areas, electric conductor trenches, along access roads, equipment pads) and kept separate from other excavated material (rock and/or sub- soil) until the completion of the facility for final restoration. For proper topsoil segregation, at least 25 feet of additional temporary workspace (ATWS) may be needed along “open-cut” underground utility trenches. All topsoil will be stockpiled as close as is reasonably practical to the area where stripped/removed and shall be used for restoration on that particular area. Any topsoil removed from permanently converted agricultural areas (e.g. permanent roads, etc.) should be temporarily stockpiled and eventually spread evenly in adjacent agricultural areas within the project Limits of Disturbance (LOD) ; however not to significantly alter the hydrology of the area. Clearly designate topsoil stockpile areas and topsoil disposal areas in the field and on construction drawings; changes or additions to the designated stockpile areas may be needed based on field conditions in consultation with the EM. Sufficient LOD (as designated on the site plan or by the EM) area should be allotted to allow adequate access to the stockpile for topsoil replacement during restoration. o Topsoil stockpiles on agricultural areas left in place prior to October 31st should he seeded with Aroostook Winter Rye or equivalent at an application rate of three bushels (168 lbs.) per acre and mulched with straw mulch at rate of two to three bales per 1000 Sq. Ft. o Topsoil stockpiles left in place between October 31st and May 31st should be mulched with straw at a rate of two to three bales per 1000 Sq. Ft. to prevent soil loss. • The surface of access roads located outside of the generation facility’s security fence and constructed through agricultural fields shall be level with the adjacent field surface. If a level road design is not 3 The Limits of Disturbance (LOD) includes all project related ground disturbances and all areas within the project’s security fencing. DocuSign Envelope ID: A6F92C15-A20B-4802-8FFC-066B8543F286 3 Solar Guidelines (Rev. 10/18/2019) NYSDAM feasible, all access roads should be constructed to allow a farm crossing (for specific equipment and livestock) and to restore/ maintain original surface drainage patterns. • Install culverts and/or waterbars to maintain or improve site specific natural drainage patterns. • Do not allow vehicles or equipment outside the planned LOD without the EM seeking prior approval from the landowner (and/or agricultural producer), and associated permit amendments as necessary. Limit all vehicle and equipment traffic, parking, and material storage to the access road and/or designated work areas, such as laydown areas, with exception the use of low ground pressure equipment.4 Where repeated temporary access is necessary across portions of agricultural areas outside of the security fence, preparation for such access should consist of either stripping / stockpiling all topsoil linearly along the access road, or the use of timber matting. • Proposed permanent access should be established as soon as possible by removing topsoil according to the depth of topsoil as directed by the EM. Any extra topsoil removed from permanently converted areas (e.g. permanent roads, equipment pads, etc.) should be temporarily stockpiled and eventually spread evenly in adjacent agricultural areas within the project Limits of Disturbance (LOD); however not to significantly alter the hydrology of the area. • When open-cut trenching is proposed, topsoil stripping is required from the work area adjacent to the trench (including segregated stockpile areas and equipment access). Trencher or road saw like equipment are not allowed for trench excavation in agricultural areas, as the equipment does not segregate topsoil from subsoil. Horizontal Directional Drilling (HDD) or equivalent installation that does not disrupt the soil profile, may limit agricultural ground disturbances. Any HDD drilling fluid inadvertently discharged must be removed from agricultural areas. Narrow open trenches less than 25 feet long involving a single directly buried conductor or conduit (as required) to connect short rows within the array, are exempt from topsoil segregation. • Electric collection, communication and transmission lines installed above ground can create long term interference with mechanized farming on agricultural land. Thus, interconnect conductors outside of the security fence must be buried in agricultural fields wherever practicable. Where overhead utility lines are required, (including Point(s) of Interconnection) installation must be located outside field boundaries or along permanent access road(s) wherever possible. When overhead utilities must cross farmland, minimize agricultural impacts by using taller structures that provide longer spanning distances and locate poles on field edges to the greatest extent practicable. • All buried utilities located within the generation facility’s security fence must have a minimum depth of 18-inches of cover if buried in a conduit and a minimum depth of twenty-four inches of cover if directly buried (e.g. not routed in conduit).5 • The following requirements apply to all buried utilities located outside of the generation facility security fence: o In cropland, hayland, and improved pasture buried electric conductors must have a minimum depth of 48-inches of cover. In areas where the depth of soil over bedrock is less than 48-inches, the 4 low ground pressure vehicles that do not result in a visible rut that alters soil compaction. 5 Burial of electrical conductors located within the energy generation facility may be superseded by more stringent updated electrical code or applicable governing code. DocuSign Envelope ID: A6F92C15-A20B-4802-8FFC-066B8543F286 4 Solar Guidelines (Rev. 10/18/2019) NYSDAM electric conductors must be buried below the surface of the bedrock if friable/rippable, or as near as possible to the surface of the bedrock. o In unimproved grazing areas or on land permanently devoted to pasture the minimum depth of cover must be 36-inches. o Where electrical conductors are buried directly below the generation facility’s access road or immediately adjacent (at road edge) to the access road, the minimum depth of cover must be 24- inches. Conductors must be close enough to the road edge as to be not subject to agricultural cultivation / sub-soiling. • When buried utilities alter the natural stratification of soil horizons and natural soil drainage patterns, rectify the effects with measures such as subsurface intercept drain lines. Consult the local Soil and Water Conservation District concerning the type of intercept drain lines to install to prevent surface seeps and the seasonally prolonged saturation of the conductor installation zone and adjacent areas. Install and/or repair all drain lines according to Natural Resources Conservation Service conservation practice standards and specifications. Drain tile must meet or exceed the AASHTO M-252 specifications. Repair of subsurface drains tiles should be consistent with the NYSDAM’s details for “Repair of Severed Tile Line” found in the pipeline drawing A-5 (http://www.agriculture.ny.gov/ap/agservices/Pipeline-Drawings.pdf). • In pasture areas, it may be necessary to construct temporary fencing (in addition to the Project’s permanent security fences) around work areas to prevent livestock access to active construction areas and areas undergoing restoration. For areas returning to pasture, temporary fencing will be required to delay the pasturing of livestock within the restored portion of the LOD until pasture areas are appropriately revegetated. Temporary fencing including the project’s required temporary access for the associated fence installations should be included within the LOD as well as noted on the construction drawings. The Project Company will be responsible for maintaining the temporary fencing until the EM determines that the vegetation in the restored area is established and able to accommodate grazing. At such time, the Project Company should be responsible for removal of the temporary fences. Post-Construction restoration requirements applicable to continued use agricultural areas that suffered ground disturbance due to construction activities (typically lands outside of the developed project’s security fence). • All construction debris in active agriculture areas including pieces of wire, bolts, and other unused metal objects will need to be removed and properly disposed of as soon as practical to prevent mixing with any topsoil. • Excess concrete will not be buried or left on the surface in active agricultural areas. Concrete trucks will be washed outside of active agricultural areas. Remove all excess subsoil and rock unearthed from construction related activities occurring in areas intended to return to agricultural use. On-site disposal of such material is not permissible in active agricultural lands. Designated spoil disposal locations should be specified in the associated construction plans. If landowner agreements, LOD boundary, or Project’s land use approvals do not allow for on-site disposal, material must be removed from the site.6 6 Any permits necessary for disposal under local, State and/or federal laws and regulations must be obtained by the facility operator, with the cooperation of the landowner when required.

Any extra topsoil removed from permanently impacted areas (e.g. roads, equipment pads, etc.) should be evenly spread in adjacent agricultural project areas, however not to significantly alter the hydrology of the area. • Regrade all access roads outside of the security fencing (as determined necessary by the EM), to allow for farm equipment crossing and restore original surface drainage patterns, or other drainage pattern incorporated into the design. • Repair all surface or subsurface drainage structures damaged during construction as close to preconstruction conditions as possible, unless said structures are to be removed as part of the project design. Correct any surface or subsurface drainage problems resulting from construction of the solar energy project with the appropriate mitigation as determined by the Environmental Monitor, Soil and Water Conservation District and the Landowner. • On agricultural land needing restoration because of ground disturbance, postpone any restoration practices until favorable (workable, relatively dry) topsoil/subsoil conditions exist. Restoration must not be conducted while soils are in a wet or plastic state of consistency. Stockpiled topsoil must not be regraded, and subsoil must not be decompacted until plasticity, as determined by the Atterberg field test, is adequately reduced. No permanent project restoration activities shall occur in agricultural areas between the months of October through May unless favorable soil moisture conditions exist. • In all continued use agricultural land where the topsoil was stripped, subsoil decompaction shall be conducted prior to topsoil replacement. Following construction, all such areas will be decompacted to a depth of 18 inches with a tractor mounted deep ripper or heavy-duty chisel plow. Soil compaction results shall be no more than 250 pounds per square inch (PSI) throughout the decompacted 18 inches as measured with a soil penetrometer. Following decompaction, all rocks 4 inches and larger in size unearthed from decompaction will be removed from the surface of the subsoil prior to replacement of the topsoil. The topsoil will be replaced to original depth and the original contours will be reestablished where possible. All rocks 4 inches and larger from topsoil shall be removed from the surface of the topsoil. Subsoil decompaction and topsoil replacement must be avoided after October 1, unless approved on a site-specific basis by the landowner in consultation with NYSDAM. All parties involved must be cognizant that areas restored after October 1st may not obtain sufficient growth for stabilization 7 to prevent erosion over the winter months. If areas are to be restored after October 1st, necessary provisions must be made to prevent potential springtime erosion, as well as restore any eroded areas in the springtime, to establish proper growth. Excess stripped topsoil shall be evenly spread in the adjacent project areas, or adjacent agricultural areas (within the LOD), however, not to significantly alter the hydrology of the area. • In all continued use agricultural areas where the topsoil was not stripped, including timber matted areas, the EM shall determine appropriate activities to return the area to agricultural use. These activities may include decompaction, rock removal, and revegetation. Soil compaction should be tested in the affected areas and the affected area’s adjacent undisturbed areas using an appropriate soil penetrometer or other soil compaction measuring device as soon as soils achieve moisture equilibrium with adjacent unaffected areas. Compaction tests will be made at regular intervals of distance throughout the affected areas, including each soil type identified within the affected areas. Soil compaction results shall be measured with a soil penetrometer not exceeding more than 250 pounds per square inch (PSI), by 7 Sufficient growth for stabilization should be determined by comparison with unaffected crop production. Annual crops restored after normal planting window (as determined by the landowner or associated producer) should be stabilized with Aroostook Winter Rye at the rate of 150/100 lbs. per acre (broad cast/drill seeder).

Where representative soil density of the affected area’s collective depth measurements present compaction restrictions exceeding an acceptable deviation of no more than 20% from the adjacent undisturbed area’s mean soil density, additional decompaction may be required to a depth of 18-inches with a tractor mounted deep ripper or heavy-duty chisel plow. Following decompaction, remove all rocks unearthed from decompaction activities 4 inches and larger in size from the surface. Revegetation shall be performed in accordance with the instructions below. • Seed all agricultural areas from which the vegetation was removed or destroyed with the seed mix specified by the landowner/agriculture producer or as otherwise recommended in the Department’s fertilizer, lime and seeding guideline: [https://www.agriculture.ny.gov/ap/agservices/Fertilizer_Lime_and_Seeding_Recommendations.pdf]. Soil amendments should be applied as necessary so that restored agricultural areas’ soil properties, at minimum, reasonably reflect the pre-construction soil test results or as otherwise agreed to by the involved parties to ensure continued agricultural use. All parties must be cognizant that areas restored after October 1st may not obtain sufficient growth to prevent erosion over the winter months. If areas are to be restored after October 1st, necessary provisions must be made to restore and/or re-seed any eroded or poorly germinated areas in the springtime, to establish proper growth. Monitoring and Remediation Project Companies shall provide a monitoring and remediation period of one complete growing season following the date upon which the desired crop is planted. All projects subject to NYS Public Service Law Article 10 will provide a monitoring period of two complete growing seasons following the date upon which the project achieves the establishment of the desired crop. On site monitoring shall be conducted seasonally at least three times during the growing season (Spring, Summer, Fall). Monitoring is required to identify any remaining impacts directly associated with the construction of the project on agricultural lands proposed to remain or resume agriculture production, including the effects of climatic cycles such as frost action, precipitation and growing seasons to occur, from which various monitoring observations can be made. NYSDAM expects the Project Company (or its contractor) to retain the EM for follow-up monitoring and remediation (as needed) in agricultural areas. Monitoring is limited to the restored agricultural area. Non-project related impacts affecting the restored project area will be discussed with NYSDAM staff and considered for omission from future monitoring and remediation. The EM is expected to record the following observations from onsite inspections:8 • Topsoil Thickness and Trench Settling – The EM observations may require small hand dug holes to observe the percentage of settled topsoil in areas where the topsoil was stripped, or trenching was performed without stripping topsoil. Observations concerning depth of topsoil deficiencies shall require further remediation by re-appropriating additional topsoil. Acceptable materials for remediation are: known areas of native excess topsoil (according to records of project specific excess topsoil disposal spread within the original LOD) or imported topsoil free of invasive species that is consistent with the quality of topsoil on the affected site. 8 The activities that follow are not necessary for restored agricultural lands on which the farmer or landowner has commenced activities, including agricultural activities or other use that tend to reverse restoration or create conditions that would otherwise trigger restoration. Should NYSDAM contend upon inspection that conditions indicate that post-construction restoration activities were improperly performed or insufficient, NYSDAM may inform the project company and NYSERDA for further investigation and remediation. DocuSign Envelope ID: A6F92C15-A20B-4802-8FFC-066B8543F286 7 Solar Guidelines (Rev. 10/18/2019) NYSDAM • Excessive Rock (>4-inches) - Determined by a visual inspection of disturbed areas as compared to unaffected portions of the same field located outside the construction area. Observations concerning excess stone material in comparison to off-site conditions shall require further remediation including removal and disposal of all excess rocks and large stones. • Soil Compaction - Project affected agricultural soils should be tested using an appropriate soil penetrometer or other soil compaction measuring device. Compaction tests will be made at regular intervals of distance throughout the access or work areas, including each soil type identified on the affected agricultural areas. Where representative soil density of the affected area exceeds the representative soil density of the unaffected areas, additional decompaction may be required. Consultation with NYSDAM staff and the agricultural producer(s) should be conducted prior to scheduling additional decompaction. If warranted, decompaction to a depth of 18-inches with a tractor mounted deep ripper or heavy-duty chisel plow. Restoration of displaced topsoil to original depth and re-establish original contours where possible. Decompaction deep shattering will be applied during periods of relatively low soil moisture to ensure the desired mitigation and to prevent additional soil compaction. Oversized stone/rock (Four-inches) material that is uplifted/unearthed to the surface as a result of the deep shattering will be removed. • Drainage – The EM shall visually inspect the restored agricultural areas in search of pervasive stunted crop growth due to seasonal saturation, not previously experienced at the site and not resulting from the agricultural producer’s irrigation management or due to excessive rainfall. Identified areas of stunted crop growth shall be compared to the nearest undisturbed adjacent areas under a substantially equivalent terrain and crop management plan. Drainage observations should be evaluated to determine if the project affected surface or sub-surface drainage during construction or restoration. Project caused drainage issues affecting or likely to reduce crop productivity of the adjacent areas will have to be remediated via a positive surface drainage, sub-surface drainage repair or an equivalent. • Agriculture Fencing and Gates – The EM shall inspect Project associated fencing and gates (installed, altered or repaired) within the Project’s LOD associated with agricultural activities for function and longevity. The Project Company is responsible during the Monitoring and Remediation Phase for maintaining the integrity of Project associated fencing and gates. The Project Company (or its contractor) shall consolidate each applicable growing season’s observations into an annual report during the monitoring period and shall be provided upon request to NYSDAM. Annual reports should include date stamped photographs illustrating crop growth in comparison with unaffected portions the agricultural areas. The EM shall record observations of the establishment of the desired crop and subsequent crop productivity within restored agricultural areas and shall be evaluated by comparing its productivity to that of the nearest adjacent undisturbed agricultural land of similar crop type within the same field. If a decline in crop productivity is apparent the Project Company as well as other appropriate parties must determine whether the decline is due to project activities. If project activities are determined to be the primary detrimental factor, the project EM will notify NYSDAM concerning unsuccessful restoration and to potentially schedule a NYSDAM staff field visit. If project restoration is determined to be insufficient, the Project Company will develop a plan for appropriate rehabilitation measures to be implemented. NYSDAM staff will review and approve said plan prior to implementation. Additional monitoring may be required depending on additional restoration activities needed. DocuSign Envelope ID: A6F92C15-A20B-4802-8FFC-066B8543F286 8 Solar Guidelines (Rev. 10/18/2019) NYSDAM The Project Company is not responsible for site conditions and/or potential damages attributable to the agricultural producer’s land use management or others’ land use management. Decommissioning If the operation of the generation facility is permanently discontinued, remove all above ground structures (including panels, racking, signage, equipment pad, security fencing) and underground utilities if less than 48- inches deep. All concrete piers, footers, or other supports must be removed to a minimum depth of 48-inches below the soil surface. The following requirements apply to electric conductors located at the respective range of depth below the surface: • 48-inches plus: All underground electric conduits and direct buried conductors may be abandoned in place. Applicable conduit risers must be removed, and abandoned conduit must be sealed or capped to avoid a potential to direct subsurface drainage onto neighboring land uses. • Less than 48-inches: All underground direct buried electric conductors and conductors in conduit and associated conduit with less than 48-inches of cover must be removed, by means of causing the least amount of disturbance as possible. Access roads in agricultural areas must be removed, unless otherwise specified by the landowner. If access is to be removed, topsoil will have to be returned from recorded project excess native topsoil disposal areas, if present, or imported topsoil free of invasive species that is consistent with the quality of topsoil on the affected site. Restore all areas intended for agricultural production, according to recommendations by the current landowner or leasing agricultural producer, and as required by any applicable permit, the Soil and Water Conservation District, and NYSDAM. Monitoring and restoration requirements in accordance to the prior sections of these guidelines, will be required for the decommissioning restoration. NYSDAM requires notice before the Project Company undertakes decommissioning. _______________ (Project Company) hereby agrees to use best efforts to adopt and employ the provisions of the NYSDAM Guidelines for Agricultural Mitigation for Solar Energy Projects in all material aspects of the construction, post construction and decommissioning of this project. Where Project Company determines that it cannot perform an activity in a manner that meets the material terms of any provision of the Guidelines, the Project Company or its Environmental Monitor will notify NYSDAM and make good faith efforts to devise an alternative solution that will mitigate adverse agricultural impacts. ______________________ _________ Signature Date DocuSign Envelope ID: A6F92C15-A20B-4802-8FFC-066B8543F286 Carrowmoor Solar, LLC 3/17/2023 EXHIBIT C – Decommissioning Estimate Category Deco Total MODULES $37,500.00 BESS $37,500.00 MODULE MOUNTING $28,000.00 BOS EQUIPMENT $12,500.00 INVERTERS $12,000.00 DAS $2,000.00 ELECTRICAL - MATERIAL Array Wiring $12,500.00 MV overhead conductor & equipment $3,400.00 DC equipment $40,000.00 $25,500.00 LABOR Racking Removal $55,000.00 Module Removal $10,000.00 CIVIL FEATURE REMOVAL Access Roads & Laydown areas $55,000.00 Stormwater management features removal $17,500.00 Trenching & directional boring $10,000.00 Seeding / Hydroseeding $12,500.00 Equipment & Storage Pads $5,000.00 FENCING & GATE $14,000.00 CONSTRUCTION MANAGEMENT Permits $2,000.00 Environmental Monitor $4,500.00 General Conditions $3,500.00 TOTAL $399,900.00 This Decommissioning Plan and Estimate for Carrowmoor Solar, as prepared by Nexamp and LaBella Associates, dated 4/28/2023, and last revised 8/11/2023, has been reviewed by a Professional Engineer licensed in the State of New York: Name and Title: Lauren Rodriquez, PE, Civil Engineer Date: Issued 8/11/2023 Solar Glint Glare Analysis Prepared for: Nexamp 1349 Mecklenburg Road Ithaca, NY 14850 Submitted by: LaBella Associates 105 N.

The project area is situated in the central portion of the property. Topography generally slopes west to east, from an elevation of approximately 1130 feet (above sea level) to 1080 feet. The project area is bordered to the east, north, and west by existing, mature trees on the property. Additional vegetative screening is proposed to the south along Mecklenburg Road. The neighboring properties consist of mostly agricultural land and residential buildings. The nearest crossing N -S roads along Mecklenburg Road are Sheffield Road, approximately 6,000 feet to the west, and Trumansburg Road, approximately 6,100 feet to the east. The nearest E-W road to the north is Bundy Road, approximately 2,100 feet from the project limits. There are no airports located within 2 miles of the project area. The subsequent Glint Glare Analysis takes into account the project area, site topography, proposed panels, and both existing and proposed screening to determine the impact of the proposed solar array on received glint and glare at various analysis points adjacent to the site. 1.1 Regulatory Context and Requirements The Federal Aviation Agency (FAA) issued a regulatory guidance under 78 FR 63276 Interim Policy, FAA Review of Solar Energy System Projects on Federally Obligated Airports, along with the Technical Guidance for Evaluating Selected Solar Technologies on Airports in 2010 (updated in 2018), which will be collectively referred to as FAA guidance. The FAA guidance recommends that a glint glare analysis should be performed with site specific data using the Sandia National Laboratories (Sandia) Solar Glare Hazard Analysis Tool (SGHAT), which is a modeling and compliance analysis tool licensed by ForgeSolar GlareGauge. This glare analysis is not mandatory for solar sites not on federal airport property; however, it is considered industry best practice to perform this analysis for all solar facilities. In addition, local approving governments can require or request a glare analysis as part of their approvals. The Town of Ithaca has requested that a Glint Glare Analysis be completed for the Project. 1.2 Glare Analysis Method The Sandia SGHAT software, as licensed by ForgeSolar GlareGauge, is a web -based tool to evaluate potential glare associated with solar array installations. The tool generates quantitative assessments of where and when glare will occur, along with information about potential ocular impacts. Calculations are based on test data and models developed over the course of several years at Sandia. Glare is possible from solar panels due to their ability to reflect sunlight from their surface to surroundings. Although solar panels are constructed of dark, light-absorbing materials, the actual photovoltaic surface is typically covered in a smooth glass with an anti-reflective coating. While anti- reflective glass coatings can reduce the quantity of reflected light, based on Sandia’s test data, it does not mitigate it altogether. The driving factor behind the incidence and intensity of reflections from a solar panel is based on their position relative to the sun. When light hits a reflective object, the angle at which the light shines on the object (the incidence angle) is always equal to the reflection angle. Per Sandia’s studies, as the incidence angle increase, the percentage of sunlight reflected also increases. The image below from ForgeSolar depicts this phenomenon. Glint-Glare Analysis 2230713 Page 4 While solar panels are designed to absorb up as much of the received sunlight as possible to produce energy, the tilt angle of the panels greatly impacts the efficiency of the panel’s optimal sunlight absorption. Systems with a lower installed tilt angle have the potential to reflect a large percentage of received sunlight when the sun is also low (during early morning and late afternoon hours), as this creates a larger incidence angle. As shown later in this report, there are multiple mitigation techniques to address the potential for early morning and late afternoon glare, if they are present. In addition to the effects of sun angle, site topography and the relative height of analysis points influence the results. Early morning and late afternoon glare are possible with the combination of low tilt angles and a site that is higher in elevation than the analysis points. Mid-day glare is possible when the site is lower than the surrounding analysis points. 1.3 Glint vs. Glare The phrase “Glint and Glare Analysis” has been used to generally describe an analysis of potential ocular impacts to defined receptors across the industry. Glint and Glare both describe the physical phenomenon of light reflecting off of a surface onto another object – the only difference between the two is duration. Glint is defined as a momentary flash of bright light (often caused by a reflection from a moving source). Glare is defined as a sustained source of bright light, generally from stationary objects. The SGHAT tool analyzes glare on a minute-by-minute basis, and generally refers to all glint or glare durations as “glare”. The SGHAT tool further breaks down their definition of glare into three categories: • Green glare – low potential to cause after-image (flash blindness) • Yellow glare – potential to cause temporary after-image • Red glare – potential to cause retinal burn (permanent eye damage) These categories factor in a typical blink response in the observer, along with the physical optical properties of the human eye. To put green, yellow, and red glare into context, directly viewing the sun without protection rests on the border of yellow and red glare. Since solar panels do not focus reflected sunlight, only green and yellow glare are typical. Glint-Glare Analysis 2230713 Page 5 2.0 GLARE ANALYSIS 2.1 Overview The Glare Analysis consists of the limits of the proposed solar array, nearby locations and routes for analyzing potential glare, and “obstruction”, or screening, that is within the property limits of the proposed solar array. The GlareGauge Model uses Google Earth locations and elevations to analyze the glare. However, within the project limits, elevations and locations based off the project’s topographic survey, were manually entered to improve the accuracy of the model. 2.2 Identification of Receptors LaBella used best practices and FAA guidelines to select the following Observation Point Receptors (OPRs) for the project: • Dwellings with potential to receive glare that are inhabited and located adjacent to the property of the proposed solar array • The nearest public roads North, South, East, and West of the proposed solar array • Documented flight paths within 2 miles of the proposed solar array To ensure a comprehensive analysis of potential glare for the Project, two-story adjacent dwellings were analyzed at both first and second story heights. Routes were analyzed at the typical eye level of a passenger vehicle. No flight paths are located within 2 miles of the proposed solar array. Please refer to the table below for a description of the OPRs and routes analyzed: Table 1: Observation Point Receptors Observation Point Number Height Above Ground (ft) Description OP 1 6 One-story adjacent dwelling to the west OP 2 6 One-story adjacent dwelling to the west OP 3 6 One-story adjacent dwelling to the west OP 4 6 Two-story adjacent dwelling to the west OP 5 15 Two-story adjacent dwelling to the west (2nd story of OP 4) OP 6 6 One-story adjacent dwelling to the west OP 7 6 Two-story adjacent dwelling to the west OP 8 15 Two-story adjacent dwelling to the west (2nd story of OP 7) OP 9 6 Two-story adjacent dwelling to the west OP 10 15 Two-story adjacent dwelling to the west (2nd story of OP 9) OP 11 6 Two-story adjacent dwelling to the west OP 12 15 Two-story adjacent dwelling to the west (2nd story of OP 11) OP 13 6 Two-story adjacent dwelling to the west Glint-Glare Analysis 2230713 Page 6 Observation Point Number Height Above Ground (ft) Description OP 14 15 Two-story adjacent dwelling to the west (2nd story of OP 13) OP 15 6 Two-story adjacent dwelling to the west OP 16 15 Two-story adjacent dwelling to the west (2nd story of OP 15) OP 17 6 Two-story adjacent dwelling to the west OP 18 15 Two-story adjacent dwelling to the west (2nd story of OP 17) OP 19 6 Two-story adjacent dwelling to the south OP 20 15 Two-story adjacent dwelling to the south (2nd story of OP 19) OP 21 6 Two-story adjacent dwelling to the south OP 22 15 Two-story adjacent dwelling to the south (2nd story of OP 21) OP 23 6 One-story adjacent dwelling to the south OP 24 6 One-story adjacent dwelling to the south OP 25 6 Two-story adjacent dwelling to the south OP 26 15 Two-story adjacent dwelling to the south (2nd story of OP 25) OP 27 6 Two-story adjacent dwelling to the east OP 28 15 Two-story adjacent dwelling to the east (2nd story of OP 27) OP 29 6 One-story adjacent dwelling to the east OP 30 6 One-story adjacent dwelling to the east OP 31 6 One-story adjacent dwelling to the east OP 32 6 One-story adjacent dwelling to the east OP 33 6 Two-story adjacent dwelling to the east OP 34 15 Two-story adjacent dwelling to the east (2nd story of OP 33) OP 35 6 Two-story adjacent dwelling to the east OP 36 15 Two-story adjacent dwelling to the east (2nd story of OP 35) OP 37 6 Two-story adjacent dwelling to the south OP 38 36 Two-story adjacent dwelling to the south (2nd story of OP 37) OP 39 6 Two-story adjacent building to the south OP 40 36 Two-story adjacent dwelling to the south (2nd story of OP 40) Route: Bundy Road (SR 138) 4 Public Road to the North Route: Mecklenburg Road into Hector Street (SR 007) 4 Public Road to the West Route: Sheffield Road (SR 172) 4 Public Road to the South Glint-Glare Analysis 2230713 Page 7 Observation Point Number Height Above Ground (ft) Description Route: Trumansburg Road into Cliff Street (SR 096) 4 Public Road to the East In addition, the images below show the locations and limits of the Observation Points and Route Receptors: Image 1: A close-up view of the proposed array, observation points, and vegetative obstruction path Image 2: A zoomed-out view showing the four route-receptors Glint-Glare Analysis 2230713 Page 8 2.3 General Assumptions The table below describes the model inputs used for the project, and identifies project specific, general, and default values entered.

One hour should be added for daylight savings. • The GlareGauge Model simplifies the geometry of the solar array due to analytical and computational limitations of the software. Detailed geometry, such as gaps in between panels and rows, is not accounted for in the algorithm, which creates a conservative analysis of potential glare. Actual glare may be less than the model prediction. • The GlareGauge Model uses the distance from the ground to the centroid of the panel for the entered ground clearance value, not the upper limits of the panel. Glint-Glare Analysis 2230713 Page 9 • The GlareGauge Model is limited to a single back-tracking resting angle (versus a more realistic back-tracking algorithm that is typically implemented with a tracker controller system). Modeling a more realistic back-tracking algorithm may impact the glare durations predicted in the assessment. • Only obstructions within the property limits of the proposed solar array were accounted for in the model. Outside of the proposed obstructions, the GlareGauge Model analyzes the glare potential with a “bare earth”, neglecting any and all existing vegetation or other potential obstructions that would limit or reduce the potential for glare. • The GlareGauge Model assumes that a tracking solar panel will return to a 0 degree resting angle at sunset and sunrise, which is not true in practice. A resting angle of 0 at these times produces a high amount of predicted glare. Therefore, a resting angle of 60 degrees, which is the maximum title angle for the project, has been used instead to better represent actual conditions. A 0 degree resting angle will only be used during non-daylight hours, if needed. • The glare results for route receptors are reported in one-minute intervals. However, the typical route receptor, which would be a passing vehicle, would experience any proposed glare for a matter of seconds, resulting in momentary glint rather than continuous glare being observed at these locations. 3.0 RESULTS The results of the GlareGauge Model show that no glare is predicted to occur at any of the 40 Observation Point Receptors, or 4 Route Receptors. These results are presented in Table 4-1. For reference purposes, the output of the Forge Solar GlareGauge software is provided in Appendix A.

For Daylight Savings, add one hour. Glare analyses do not automatically account for physical obstructions between reflectors and receptors. This includes buildings, tree cover and geographic obstructions. Detailed system geometry is not rigorously simulated. The glare hazard determination relies on several approximations including observer eye characteristics, angle of view, and typical blink response time. Actual values and results may vary. The system output calculation is a DNI-based approximation that assumes clear, sunny skies year-round. It should not be used in place of more rigorous modeling methods. Several V1 calculations utilize the PV array centroid, rather than the actual glare spot location, due to algorithm limitations. This may affect results for large PV footprints. Additional analyses of array sub- sections can provide additional information on expected glare. The subtended source angle (glare spot size) is constrained by the PV array footprint size. Partitioning large arrays into smaller sections will reduce the maximum potential subtended angle, potentially impacting results if actual glare spots are larger than the sub-array size. Additional analyses of the combined area of adjacent sub-arrays can provide more information on potential glare hazards. (See previous point on related limitations.) Hazard zone boundaries shown in the Glare Hazard plot are an approximation and visual aid. Actual ocular impact outcomes encompass a continuous, not discrete, spectrum. Glare locations displayed on receptor plots are approximate. Actual glare-spot locations may differ. Refer to the Help page for detailed assumptions and limitations not listed here.

Nexamp’s veteran team of power and solar professionals understands what it takes to manage, maintain and deliver ongoing performance and reliability from our solar plants. We provide full spectrum operations and maintenance services for our own, as well as third party systems. Our team actively monitors and provides preventative, corrective, and condition-based maintenance for over Hundreds of MWs at commercial, residential and government owned plants in NY and across the Country. This wide range of managed assets gives our team unprecedented knowledge that helps us keep facilities on-line and delivering clean, renewable energy to our customers consistently, with little downtime. Our integrated O&M team should give the Town of Ithaca the confidence it needs to know that the 5 MW facility we’re seeking to permit will remain operational, and not prove to be a burden on the Town or its residence at any point during the facilities operation. This Operations and Maintenance plan serves as an outline for the maintenance services and schedules that will be employed at Carrowmoor Solar. This plan will be filed with the Town codes office for reference and use during inspections. Nexamp will be held responsible to adherence of this plan, and shall notify the town if changes are made to the plan within 30 days of modification. Site Description and Access Carrowmoor Solar , LLC (The Company), has prepared this Decommissioning Plan (Plan) for its proposed solar photovoltaic facility to be constructed on private property located at Mecklenburg Rd, Ithaca, NY, tax map number 27-1-15.2 . The parcel is .36 miles West of Westhaven Rd and 1.2 mi East of Sheffield Rd. The site includes a solar array, mounted using Single-Axis trackers on approximately 39 acres of open field. The system is accessed via an access road from Mecklenburg road, and is encompassed by a 8ft tall farm fence for security and wildlife management. The system includes 2 central inverters, and energy storage facilities. Nexamp is responsible for the entire leased area of the facility, including all easement areas and storm water control maintenance and improvements. The facility will be actively monitored 7 days a week, 365 days a year. Access to the site will be through keyed entry and knox boxes will be located at the facility entrance for emergency response purposes. Site access for vendors and/or town inspection officials will be coordinated by Nexamp Asset Management Services. Parking during construction will be restricted to the temporary construction laydown area as shown in the Site Plan Designs submitted in August 2023. Parking for the site shall occur on access road spurs during operations. Site plan designs have been included on this plan as an appendix for reference. 4 Carrowmoor Solar, LLC – Draft Operations and Maintenance Plan –August 2023 – v3 5 Carrowmoor Solar, LLC – Draft Operations and Maintenance Plan –August 2023 – v3 Stakeholders and Responsibilities Role Contact Information Carrowmoor Solar, LLC System Owner Attn:Carrowmoor Solar 101 Summer St, Flr 2 Boston, MA 02110 Phone: 617.431.1440 Email: Legal@Nexamp.com Nexamp Asset Management Services System Operations Manager Attn:Carrowmoor Solar Attn: Skip Provost 101 Summer St, Flr 2 Boston, MA 02110 Phone: 978.910.1503 Email: sprovost@nexamp.com Town of Ithaca– Codes Office Town Code Enforcement and Site Inspection Town of Ithaca Codes Office 215 N Tioga St Ithaca, NY 14850 Phone: 1 607 273 1721 Town of Ithaca– Planning Board Site Plan Jurisdiction Town of Ithaca Codes Office 215 N Tioga St Ithaca, NY 14850 Phone: 1 607 273 1721 Rancich Family Limited Partnership Landowner PO Box 547 Ithaca, NY, 14851-0547 NYS DOT Region 3 Curb Cut Administrator State Office Building 333 E.

Following the dispatch, the Local Fire Department will be in constant communication with the BESS SME and Emergency Response Coordinator as to define and establish safe setbacks from the project site and/or equipment. Simultaneously to defining the setbacks, the BESS SME will inform the Local Fire Department of BESS status as it relates to the data relayed from the BESS Operator and the expertise of the BESS SME. 17 5 Safety Guidelines The BESS Operator, BESS SME, Emergency Response Coordinator, and Emergency Response personnel are required to read and follow all safety measures and procedures for the components of the BESS, such as: controls, battery systems, inverters, meters, and shelters. The BESS operator must contact the BESS manufacturer and/or an authorized SME immediately if any questions exist concerning the safe use of the equipment discussed in this document. Nexamp is responsible for making the Emergency Response Plan and associated safety documentation available to personnel tasked with equipment operation and maintenance, as well as emergency response. 5.1 OSHA (Occupational Safety and Health Administration) The BESS manufacturer has designed and built this equipment to conform to machine building safety standards such as ANSI (AMERICAN NATIONAL STANDARDS INSTITUTE). Nexamp is responsible for reviewing the equipment once installed and addressing its conformance to OSHA and/or local standards at their facility. OSHA Standards Conformance would be applicable to: • Title 29, Part 1910 of the Code of Federal Regulations (29 CFR 1910), Safety and Health Regulations for Construction • Title 29, Part 1926 of the Code od Federal Regulations (29 CFR 1926), Safety and Health Regulations Construction Nexamp is also responsible for training their personnel to OSHA safety standards prior to operating or serving the BESS. 5.2 BESS Operator Safety The following guidelines are general recommendations for BESS operator safety: • Inspect equipment remotely daily for unsafe conditions • When servicing the BESS, keep hands away from exposed electrical connections, including: o Improper grounding § The most common OSHA electrical violation is the improper grounding of equipment. Proper grounding can eliminate unwanted voltage and reduce the risk of electrocution. Never remove the metallic ground pin as it is responsible for returning unwanted voltage to the ground o Damaged insulation § Defective or inadequate insulation is a hazard. Be aware of damaged insulation and report it immediately. Turn of all power sources before replacing damaged insulation and never attempt to cover them with electrical tape. o Wet conditions § Never operate electrical equipment in wet locations. Water increases the risk of electrocution especially if the equipment has damaged insulation. Have a qualified electrician inspect electrical equipment that has gotten wet before energizing it. • Keep hands away from hot surfaces • Observe all high voltage warnings • Any outstanding observations shall be reported to the personnel’s supervisor immediately and documented 5.3 Personal Protective Equipment There are various levels of PPE (Personal Protective Equipment) that must be checked and maintained. All personnel who wear levels of protection beyond their normal everyday attire must be trained in that 18 PPE. All training of PPE shall be conducted by a competent person or company. The training shall be documented. Some types of PPE have SCAM (selection, care, and maintenance) documentation that will instruct the end user on the limitations of the PPE and the proper maintenance of PPE. Always be aware of individual equipment operational requirements and hazards as well as out of service dates. All PPE is required to be always worn for the work being conducted. Any PPE that is compromised or no longer considered viable for protection shall be discarded and replaced. Any PPE that comes in contact with hazardous material shall be properly decontaminated and inspected for functionality before being returned to service. 6 Emergency Response Actions The primary responsibility of the BESS Owners and Operators is to understand the site-specific Emergency Response Plans and be knowledgeable about the responses to take when an emergency occurs. The BESS controls will be programmed to isolate the system from the grid and the electrical customer upon an emergency and will send emergency communications to the BESS Operators informing them of the situation. In most cases, the primary role of the BESS Operators will be to confirm that the BESS is taken offline safely, and to contact the Local Fire Department to go to the BESS location and to coordinate with the Emergency Response Coordinator and BESS SME. The BESS Operator would receive an alarm, and then refer to the Nexamp BESS Emergency Response Plan Call Tree to proceed forward with the necessary communications to other emergency response stakeholders. 19 The phases of emergency response are described by the term APIE: Analyze, Plan, Implement, and Evaluate. 1 2 3 4 Analyze Plan Implement Evaluate Analyzing the emergency is the phase in which the notification takes place to emergency responders. Planning the response is the phase in which the proper resources and equipment are called to the emergency scene and a plan is developed to mitigate the emergency. Once a plan is developed and the proper resources and equipment are installed, the Emergency Response Coordinator will make the determination to implement the plan Once the plan is implemented, it shall be evaluated for safety and effectiveness. If the plan is not safe, restart the APIE process. 6.1 Emergency Response Recommendations Initiator of emergency response shall be activated as per the following protocol. 1. If there is any threat or potential threat to life safety (e.g., toxic plume, explosion, etc.), 911 shall be called immediately to summon the aid of public safety responders to support the Local Fire Department. The Emergency Response Coordinator and BESS SME will also be contacted immediately (three-way call if possible). 2. An initial scene size-up shall be conducted from all sides if possible and a clear concise size-up shall be given to incoming emergency responders. The scene size-up shall include the following: • Where is the incident located? • What has happened? • What is occurring? • Are there any injuries or unaccounted for individuals? • What the needs/site resources are? 3. Onsite staff and visitors shall immediately go to a designated assembly point for accountability. 4. Incident command shall designate the individual in charge of accountable and accountability shall be reported as soon as possible. 5. Another individual shall control any traffic and guide first responders into the scene. At the same time as these activities are occurring the Nexamp’s designated Subject Matter Expert (SME) shall immediately gather and review available data from the Battery Management System (BMS) and communicate this to the appropriate incident command individual. 20 6.2 Condition Monitoring and Alarms The BYD Cube Pro and its control systems are engineered to react to fault conditions in an autonomous manner, with safeguards built into the firmware. These fault conditions include over-temperature, loss of communication, overvoltage, and isolation. The BESS has been designed with monitoring systems for temperature, current, and voltage, which provide real-time data of conditions within each of the BESS containers, battery modules, battery racks, and inverters. Historical data may be provided for additional insight as well. Furthermore, the real-time data is relayed to Tesla and is also available at Nexamp's NOC. The SME may be able to interpret the conditions inside the BESS containers to the fire department. 21 7 Site Overview 7.1 Site Location Address: 1340 Mecklenburg Rd, Ithaca, NY 14850 Municipality/County: Town of Ithaca, Tompkins County 7.2 System Specification/Description System size: 5 MW / 20.88 MWh (DC usable) Battery Manufacturer: BYD Battery technology: Lithium-ion iron phosphate (LFP) battery cell chemistry.

This shall include proper use of Self-Contained Breathing Apparatus (SCBA). If no fire or explosion risk is present, protective clothing to protect against arc flash and shock shall be worn. REMEMBER: Jewelry such as necklaces and bracelets shall be removed to avoid contact with any electrical hazard. 28 9 Safety Systems - BESS The following figures provide an overview of the BESS safety systems. Commented [RM3]: @Mohamed Kassamali - please add BYD details Commented [MK4R3]: Updated accordingly 29 30 10 Specific Recommendations for Emergency Response Personnel (By Type of Emergency) 10.1 Fire In the event a first level alarm (heat, smoke, gas, etc.) is triggered, the alarm bell will ring. a fire signal will be sent to Nexamp. The system will automatically enter an emergency shutdown to protect the BESS and any equipment connected to it (Inverter, site controller, etc.). Upon second detection of fire or smoke, the audible and visual alarms are activated and Nexamp will be notified. At this point Nexamp will be communicating the state of the emergency to the Ithaca Fire Department and will dispatch Nexamp personnel for support. Once the Fire Department is on site, a secure perimeter should be established. A minimum of one hundred (100 ft) shall be maintained between individuals and the incident BESS unit. The emergency event should be monitored from this minimum approach distance. It is advised that the fire department not take direct action to suppress the fire. A communication link between the fire department and Nexamp to obtain data regarding the BESS status if available. This data may include battery status, temperature, and voltage trends which will be observed to quantify the scope and threat associated with the event. If the fire department is equipped with Infrared (IR) cameras can also be used to evaluate hot spots and decreasing/increasing temperatures. It is recommended that a defensive approach is initially taken where the “let it burn” method is utilized. It is recommended that any personnel should only approach the BESS units when determined safe to do so by an incident commander, Nexamp, or other qualified authority If there is an immediate threat to life safety of personnel on site or it is determined as appropriate and safe to approach the BESS by the incident command, water can be applied to the BESS unit and adjacent structures to prevent the spread of the fire. Personnel and equipment shall be on the angles of the cabinet to stay out of the blast pressure wave as much as possible and the blast radius of any doors or other potential projectiles. Only attempt to extinguish fire if imminent threat to life safety exists. If no life safety hazard exists, a defensive approach should be considered utilizing water to cool and protect adjacent exposures and mitigate the spread of any fire. Vegetation shall be controlled and maintained as to not add any additional fuel source that could result in spreading of a fire. Lithium-ion fires pose a risk of re-ignition. It is best to allow the system to burn in a controlled fashion until all fuel sources are depleted, if possible. If incipient stage fire is found to be present and it is safe to do so, use copious amounts of water to extinguish and continue to cool to lessen chance of re-ignition. All personnel should be prepared for fire as heat is trapped within the system. Chemicals released during a fire or explosion will be in a gaseous form and primarily pose an inhalation hazard. A fog pattern from a handline or monitor nozzle may be an effective way to control the off-gassing event on the exterior of the cabinet from migrating to unwanted areas. However, if water is used in 31 extinguishing flames, these gasses can become acids which may cause skin irritation. Water curtains or hose streams may be applied to adjacent exposures for cooling purposes. If any indicators are present of damage or heat to an adjacent system, the BMS data shall be closely monitored for the adjacent system and relayed to the appropriate individual within the Incident Command System. Following partial or complete consumption of the system by fire, batteries may continue to emit low levels of flammable gases and dangerous levels of toxic gases for an extended period. Continuous monitoring of gas levels in and around the incident location shall be conducted and use of mechanical ventilation may be utilized to manage gas levels. Full firefighter PPE and SCBA shall be utilized until gas levels are confirmed to be at a safe level. For burning clothing, extinguish the flames with water, rolling on the ground to smother the flames. Any fire incident in which the fire department did not respond shall be reported to the Ithaca Fire Department immediately for notification purposes. Do not enter the enclosure or are prior to complete venting of the enclosure. Use filter mask as necessary during clean-up. Each BESS unit is equipped with a Fire Department Connection (FDC) which may be used in the event of a fire to flood the system. The FDC can be connected to a fire engine or other water supply. 10.2 Explosion In the event sensors within the BESS units detect flammable gas or a thermal runaway event, the BESS unit undergoes an emergency stop of operations, including isolation of batteries. Upon detection of flammable gas (hydrogen), the audible and visual alarms are activated, and the exhaust ventilation system will be activated. The exhaust ventilation system will actively remove flammable gas from the BESS unit as to keep the buildup of any potential flammable gas below 25% of the LEL. Simultaneously, Nexamp will be notified. At this point Nexamp will be communicating the state of the emergency to the Rehoboth Fire Department and will dispatch Nexamp personnel for support. Once the Fire Department is on site, a secure perimeter should be established. A minimum of one hundred (100 ft) shall be maintained between individuals and the incident cabinet. Personnel and equipment shall be on the angles of the cabinet to stay out of the blast pressure wave as much as possible and the blast radius of any doors or other potential projectiles. There are also three (3) pressure valves to provide passive deflagration/explosion protection. Lithium batteries off-gas when heated or when subjected to electrical or physical damage. These gases can accumulate inside the container at levels above the Lower Explosive Limit (LEL), especially if the fire suppression system has been discharged. However, the buildup of gas will be managed by the exhaust ventilation system. However, extreme caution shall be taken prior to any manual ventilation or attempts to open any compartments or doors on the system as the introduction of fresh air may bring atmospheric condition back into the explosion range and result in an explosion if fire or other ignition source is or becomes present. The responder preparing to open any door or compartment shall stand to the side to eliminate the risk of being directly in the path of the blast pressure if an explosion were to occur. Gas monitoring shall always be continuously conducted, and gas meters shall be affixed to all responders to warn of potential atmospheric risks. If possible, gas readings from inside the cabinet shall be attempted to be gathered from an exterior point prior to any entry. 32 10.3 Electric Shock All systems shall always be treated as energized (Energetic Hazardous Material). Even though a battery may look to be destroyed by fire and/or other means, there is immense potential that the battery still has stranded energy and remains. De-energization of the system or any removal of the battery or battery component shall only be performed by a trained and competent individual with appropriate PPE. 10.4 Arc Flash When inside the battery container, wear non-melting or untreated natural fiber long-sleeve shirt, long pants, safety glasses, hearing protection, and leather gloves. Fire-retardant plant clothing is also acceptable. Maintain arc flash boundary until completion of task. 10.5 Chemical Release The off gas can contain detectable levels of carbon monoxide (CO), hydrogen chloride (HCl), hydrogen fluoride (HF), and hydrogen cyanide (HCN) and other hydrocarbons and Volatile Organic Compounds. No entry to the area shall be permitted during an off-gassing event unless there is an immediate threat to life safety at which time only professionally trained and equipped public safety may enter. This entry shall be with full firefighter protective gear to include self-contained breathing apparatus (SCBA). The entry in this situation shall be at the sole discretion of the officer in charge (OIC). Chemicals released during a fire or explosion will be in a gaseous form and primarily pose an explosion hazard. However, if water is used in extinguishing flames, these gasses can become acids which may cause skin irritation. 10.6 Hazmat Considerations Runoff water from suppression shall be attempted to be contained utilizing diking, damming or other preventative measures. Barriers such as PIG chemical absorbent may be utilized to control runoff. If any storm drains or other drainage is present which may flow offsite or to the adjacent canal and not be contained to a retention area the drains should be covered with mats or protected with barriers. However, there are no storm drains or retention areas included in the site design. 33 11 Emergency Response for Non- Emergency Personnel In the event of an emergency such as a fire, off-gassing event, electrical failure, etc., and being alarmed of an emergency event (visually or audibly), all on-site personnel, contractors, visitors, and employees must evacuate the BESS area and rendezvous at the designated muster point (typically at least 100 ft from the BESS) for a head count and instructions. The designated operations personnel responsible for the safe shutdown of the plant (if the automatic shutdown has not occurred yet) will adhere to this ERP. Once an emergency is discovered external or internal to the BESS the following actions will be taken by the Nexamp operator: • Contact the Local Fire Department and Nexamp Emergency Response Coordinator immediately o The BESS area will be evacuated immediately, and all on-site personnel will be directed to the designated muster point for a head count § If on-site, the designated Nexamp Safety Representative will do a head count and relay any information using the Nexamp BESS Emergency Response Call Tree. o If heavy smoke is encountered, stay low and breathe through a handkerchief or other fabric; move away from the area. o Assist anyone having trouble leaving the area without putting yourself in harm's way o Remove obstructions that might impede emergency response personnel from entering the site o Station available personnel at road intersections to stop traffic flow into the fire scene o Do not leave the designated muster point until advised to do so. o The BESS Site is not to be accessed until the Emergency Response Personnel, BESS SME, and Emergency Response Coordinator agree that it is safe to enter. 12 Quick Response: Command Chart This chart is designed to provide quick reference material for rapid decision making at an event.
