1.0 INTRODUCTION
1.1 Project Description
KCE NY 26, LLC (KCE) has prepared this Expanded Environmental Assessment (Expanded
EA) and accompanying Full Environmental Assessment Form (FEAF) (Appendix A) to support
its application to the Town of Southold for approvals including special exception, site plan,
subdivision and others, to facilitate its proposal to construct and operate an approximately 60-
megawatt (MV) Lithium-Ion Battery Energy Storage System Facility (BESS Facility) on one
parcel located at 10750 Oregon Road, in the Hamlet of Cutchogue, Town of Southold, Suffolk
County, New York (Proposed Action). The Proposed Action would be located on Suffolk County
Tax Map (SCTM) Number 1000-083.00-03.00-006.100, which is approximately 27.04 acres in
size (Proposed Action Site or Site). A Site Location Map is provided as Figure 1.

As part of the Proposed Action, KCE is proposing to construct a project substation, a point of
interconnection (POI) substation on the subdivided portion of the Proposed Action Site and
enter into an easement agreement with the Town to permit access to a 100 feet wide by 1,150
long area on an adjacent parcel (SCTM Number 1000-096.00-01.00-002.000) where a new
overhead transmission line would be site and travel in a southeasterly direction to Middle Road,
County Route (CR) 48.

KCE NY 26 Proposed BESS Project Expanded Environmental Assessment
Cutchogue,Town of Southold,New York
The BESS Facility would be comprised of the following elements: 272 battery modules within
containerized enclosures; 34 medium voltage transformer and inverter units located within their
own respective containers to mitigate sound and visual impacts; a project substation with control
building; a POI substation to be located on the subdivided 2.55 acre portion of the Site including
an equipment enclosure; and new overhead transmission lines and utility poles traveling to CR
48 from the southeasternmost corner of the Site. Each BESS containerized enclosure will be
approximately 30.7' long, 5.6' wide and 8.6' tall. Inverters will be sited adjacent to the battery
containers and will be approximately 19.9' long, 8' wide and 9.5' tall. The containerized battery
enclosures contain all heating, cooling, sensors, communication/control equipment, and
specialized fire suppression systems necessary to support operation of the project.
Components of the project substation include the following: lightning masts approximately 55.7
feet in height, feeder breaker bays approximately 28 feet in height, disconnect switches, bus
supports, a main power transformer (MPT) to increase and decrease the voltage of the energy
entering and leaving the BESS, circuit breakers, and an aluminum hard bus that will connect the
project substation to the POI substation.
Components of the POI substation include the following: lightning masts approximately 55.7 feet
in height, disconnect switches, circuit breakers, bus supports, and two (2) A-frame feeder
breakers approximately 28 feet in height.
KCE and Public Service Electric and Gas Long Island (PSEG LI) on behalf of Long Island
Power Authority (LIPA) will enter into an engineering, procurement and construction (EPC)
agreement for pole and transmission utility line easement work and jointly oversee the process.
Approximately 13 utility poles are planned for installation through the easement, two of which
likely would be installed on CR 48. Each pole will span 150-180 feet through the easement.
Utility poles associated with the transmission line on CR48 are expected to be at heights
consistent with LIPA's existing transmission infrastructure there, (approximately 50-70-ft),
however, the designs for this infrastructure are not available at this time. PSEG LI will have the
final determination over the design and implementation of the transmission line and associated
infrastructure and will determine construction materials, heights and construction methods.
Site improvements are anticipated to include: improvements and minimal realignment of the
existing .site access driveway to Oregon Road, construction of internal site driveways,
installation of an approximately 12-feet high visual and sound barrier wall surrounding the BESS
on its north, west and southern sides, chain link fencing around the perimeter of the BESS
installations, project substation and POI substation, landscaping to the west and south of the
BESS, and installation of a stormwater management system consisting of drywells and
associated catch basins consistent with Town and NYSDEC standards. A total of approximately
11.00 acres of land disturbance is anticipated to occur during construction activities. The
Proposed Action involves several discretionary approvals as shown in Table 1 below.
Once construction is completed, the BESS Facility will operate unmanned and on a continuous
basis 24 hours a day, seven days a week and 365 days a year. Operations and maintenance is
discussed in further detail below and is expected to be conducted pursuant to a facility
Operations and Maintenance Plan. The maintenance program will include daily and weekly
remote inspections, plus monthly, quarterly or yearly on-site inspections as appropriate for
specific components of the Proposed Action. In order to maintain optimal operating capacity, the
maintenance program will include periodic augmentation of the system, tentatively starting in the
third year of operations. This augmentation will consist of adding new battery containers and
possibly medium voltage power conversion systems. KCE NY 26's system design in this

1.2 Introduction to KCE
KCE is an Albany, New York based energy storage developer, owner, and operator that focuses.
on utility-scale BESS throughout the United States. KCE manages BESS projects throughout
their lifecycle by identifying potential project sites, acquiring all required permits determined by
the site's setting and jurisdiction, procuring the BESS equipment, overseeing construction,
executing projects into full operation, and operating them throughout their useful life through
decommissioning. As Long Island transitions to an energy supply, KCE's large-scale energy
storage projects provide a solution to store energy safely and efficiently so it can be consumed
on demand, its output can be controlled, and energy distribution can be regulated making the
grid more flexible and reliable. With founders who have spent over a decade advancing utility-
scale renewable energy projects into operations, KCE has assembled a unique team with a
deep understanding of the market and a history of development achievements that have been a
crucial part of New York's transformation into a clean energy leader.
KCE relocated its headquarters from Houston, Texas to Albany, New York in 2018 in
partnership with the University at Albany and the state's START-UP NY program, administered
by Empire State Development. Since joining START-UP NY, KCE has more than doubled the
size of its New York-based team, advancing the development of the Company's portfolio of
utility-scale BESS projects throughout New York. To further support its efforts to integrate into
the State, the company has hired several graduates from the State's University system and
favors New York State-based suppliers and service companies.
KCE developed, constructed, owns and operates the largest operational BESS in New York
State, the 20 MW KCE NY 1 Facility in Stillwater, NY. KCE's operational 4.4 MW1
12 MWh BESS, KCE NY 3, was selected by Orange & Rockland Utilities (O&R) through its
competitive Pomona Non-Wires Alternative (NWA) RFP to provide support for its Pomona load
pocket in Ramapo, NY in October 2018. KCE NY 3 will enable O&R to delay building costly new
peak-demand infrastructure while simultaneously increasing system reliability and reducing
reliance on carbon-emitting resources.
1.3 Project Purpose and Need
KCE NY 26 will support the Public Service Commission's Order Establishing Energy Storage
Goal and Deployment Policy, which outlines statewide energy storage deployment goals of
1,500 MW by 2025 and 3,000 MW by 2030. Long Island's electric grid is rapidly changing in
preparation of expected offshore wind generation and the retirements of existing fossil fuel
peaker plants. The local grid will need fast-responding, flexible solutions like battery energy
storage to accommodate these changes. KCE NY 26 will respond to intermittent grid
fluctuations to enhance the power grid by charging during periods of excess generation and
discharging during peak load hours. The Project will also enhance power grid reliability by
providing ancillary services (e.g., voltage uplift) to the New York Independent System Operator
(NYISO).

In October 2020, Strategen Consulting LLC prepared the Long Island Fossil Peaker
Replacement Study for New York Battery and Energy Storage Technology Consortium (NY-
BEST)2. The study examined operations of Long Island's aging fossil-fueled power plants that
operate primarily during peak times, and found that it is feasible and cost-effective to replace
more than 2,300 MW of Long Island's 4,300 MW fossil-fueled peaker plants with energy storage
over the next decade. It also found that approximately half of the peaker plants, around 1,100
MW, could be retired and replaced with energy storage by 2023. The remaining 1,200 MW
could be replaced by 2030, in conjunction with New York State's plans to increase solar energy,
energy efficiency measures, and offshore wind resources. Over the next
decade, fossil peaker replacements could also save LIPA customers as much as $393 million
and contribute to significantly reducing harmful air pollutants.
PSEG LI released a request for proposals in April 2021 for up to 175 MW of bulk energy storage
projects (i.e., project size greater than 20 MW) on Long Island. With the upcoming retirements
of fossil fuel peaking plants, due to the New York State Department of Environmental
Conservation nitrogen oxides regulations, and the increase in intermittent energy from offshore
wind energy projects interconnecting on Long Island, PSEG LI has identified a need for quick
responding, energy-dense resources such- as battery energy storage. PSEG LI specifically
highlighted the need to deploy energy storage in the North Fork region in the RFP
KCE NY 26 will support the Public Service Commission's order for deploying energy storage
and LIPA in meeting its share of the NYS energy storage goals.
1.4 Site Setting
The Proposed Action Site is located in the Hamlet of Cutchogue, Town of Southold. The Site is
approximately 27.04 acres and is primarily developed with active agricultural uses and contains
vacant/ overgrown agricultural fields. The northeastern portion of the Site is utilized for vehicle
and equipment storage including but not limited to cars, trucks and boats. The Site also contains
a mixed gravel and dirt road running the length of the property. Land uses adjoining the Site
include Oregon Road, residential and agricultural uses to the west, a combination of residential
and industrial uses to the northwest, a recycling facility to the north, the Town's Solid Waste
Management facility to the northeast, east and southeast, and agricultural uses to the. south.
Land uses that occur within % mile of the project site primarily include agricultural, industrial,
commercial and residential uses in addition to waste management facilities. A.map depicting the
Site of KCE NY 26 in relation to nearby existing land uses is provided in Figure 2.

Public policies applicable to the Proposed Action Site were reviewed. According to the NYSDEC
Environmental Assessment Form (EAF) Mapper and the Suffolk County ArcGIS Viewer, the Site
is located in a State designated agricultural district (SUFF001). The 2000 Southold Town Farm
and Farmland.Protection Strategy Plana and Protected Lands Map within the Town of Southold4,
indicate that the Site is not designated by the Town as protected farmland/ open space.
Regional plans applicable to the site include the LI North Shore Heritage Area; this regional plan
addresses a large swath of Long Island generally on the North Shore from the Long Island
Expressway or State Route 25 (whichever is further south), north to the Connecticut line in
Nassau and Suffolk Counties, and east to Orient Point. The LI North Shore Area Heritage Area
goals are to preserve, protect, and enhance the cultural, historical, and natural resources which
define the North Shore of Long Island and to promote responsible economic development of the
area compatible within the historical and natural environments. The Proposed Action Site is
within the New York State Coastal Zone Boundary and the boundary of the Long Island Sound
Coastal Management Program. There are no New York State Office of Parks, Recreation and
Historic Preservation (NYSOPRHP) Historic Districts or areas of potential archeological
significance on or adjoining the Proposed Action Site however two recently designated
properties eligible for listing in the National/ State Registers of Historic Places are located
adjacent to the property across Oregon Road to the northwest.
The Town of Southold .has several planning initiatives that apply to the Town and the Site. The
Site is located within the boundaries of the Town's approved Local Waterfront Revitalization
Program (LWRP)s the policies of which promote balanced preservation, .enhancement and
utilization of the valuable local waterfront resources along the Peconic. Estuary, Long Island
Sound, Gardiners Bay and Block Island Sound (see Appendix B for assessment of the
Proposed Action's consistency with the LWRP and the Town of Southold Coastal Assessment
Form). The Town of Southold adopted an updated Comprehensive Plan in February of 2020,
and the Plan contains the policies that will guide the future development of the Town. In 2005,
Town of Southold issued a Hamlet Study for Cutchogue which was also reviewed for land use
polices applicable to the Site. Neither the Comprehensive Plan nor the Hamlet.study contain site
specific recommendation for the Proposed Action Site. Of additional local note is that the Town
of Southold is a Climate Smart Community with goals to reduce greenhouse gases and
establish other energy efficiencies in the Town' and that the Town has a Farmland Protection
Strategy that designates specific parcels as protected open space and farmland but does not
identify the Proposed Action Site in those protected categories. There are not locally or
regionally designated Critical Environmental Areas on the Proposed Action Site. The Site is
located over the Long Island Sole Source Aquifer (SSA) which encompasses the entire land
area of Suffolk and Nassau counties on Long Island.

KCE believes that the Proposed Action Site is ideally suited for development as a BESS Facility
due to:
• Large site that can accommodate the BESS with large areas remaining undisturbed to
buffer views of the BESS Facility from public viewpoints on Oregon Road and Depot
Lane;
• Position relative to existing utility infrastructure;
• Lack of wetlands or waterbodies;
• No critical environmental areas or significant natural communities identified on-site;
• Position in proximity to retiring fossil generation and existing electricity loads;
• Relatively flat topography with slopes less than 10 percent throughout more than
approximately 87.70% of Proposed Action Site;
1.5 Construction Schedule
The project is anticipated to be constructed in two phases. Specifically, the transmission
easement work, POI substation, curb cuts / driveway upgrades along Oregon Road and LIPA's
road easement to the POI substation will be constructed first and is anticipated to begin in the
second quarter of 2024 and completed in 8-12 months. As discussed above, KCE and PSEG LI
will enter into an engineering, procurement and construction (EPC) agreement for the
associated transmission easement work and jointly oversee the process.
The second phase includes construction of the BESS facility; KCE intends to directly manage
the Project's Engineering, Procurement and Construction Phase (EPC) and will hire a Balance
of Plant (BOP) contractor to complete the physical construction of this portion of the project.
KCE is committed to Long Island-based construction firms and utilizing Long Island's local
workforce. At this time, construction on KCE NY 26 is expected to begin during the fourth
quarter of 2024 and will take approximately 6 to 9 months.
The number of construction workers necessary on Site at any one time will vary, depending on
the stage of construction. At the peak of construction, approximately 30 workers will be
present. Construction parking will be located on the Site and will not impact traffic along the
local roads. KCE will release a competitive BESS Request for Proposal (RFP) approximately 1
year prior to mobilizing for construction to assess battery technology improvements and
industry consolidation, for which changes are expected as the industry matures. The Project is
currently designed with a BESS and power conversion systems from Sungrow USA. KCE has
significant 'experience with Sungrow and is currently building more than 300 MW from
Sungrow which will be operational in 2022 spread across New York and Texas.
1.6 Operations and Maintenance
KCE NY 26 is designed to be an unmanned facility that will be operated 'and monitored
remotely by trained personnel, 24 hours per day, 7 days per week (24/7). The facility's
Operation and Maintenance (O&M) Plan will be based on the O&M manual from the battery
- and other equipment vendors. The O&M Plan will be compliant with the appropriate federal,
state, and local laws and manufacturers' recommendations through their supplied O&M
material. In addition, a Health, Safety, Environmental and Quality (HSEQ) Management Plan
8
KCE NY 26 Proposed BESS Project Expanded Environmental Assessment
Cutchogue,Town of Southold,New York
will be in place providing a safe work environment for employees of KCE, contractors and
visitors working at the Site.
The Project O&M Manual will consolidate the necessary and prescribed maintenance
schedules for the components in the system. The O&M will be led by KCE's ,O&M Manager
and will likely be completed by a local firm with expertise in medium and high voltage electrical
systems. The maintenance schedules will include work for on-site inspections and preventative
maintenance. The schedule will include daily and weekly remote inspections, plus monthly,
quarterly, or yearly on-site inspections as appropriate for specific components of the Project.
Maintenance logs will be maintained and recorded for all appropriate work completed at the
facility. This work will include:
• Facility inspection, cleaning, and maintenance once a quarter;
Electrical inspections once a quarter;
• System calibration;
• Power conversion system maintenance;
5
• Switchgear preventive inspection;
• Medium voltage vacuum CB preventive inspection;
• Protective relays preventive inspection;
_ Substation transformers preventive inspection;
• Fire alarm test and inspect;
• System augmentation; and
• Equipment replacement(as needed).
KCE will select an O&M Contractor based upon the final BESS vendor and design used for the
system. O&M will be managed by KCE directly.overseeing a qualified.third-party provider. The
third-party provider may be the BESS integrator or another qualified service party. KCE will
provide a copy of the O&M Plan to the Town of Southold to reference when the third-party
provider is selected.-
Utility-scale lithium-ion batteries slowly degrade over time, resulting in decreased capacity as
the project ages. To ensure KCE NY 26 can maintain its full energy capacity throughout its
operating life, KCE will augment the system periodically, tentatively starting in the third year of
operations. This augmentation will consist of adding new battery containers and possibly
medium voltage power conversion systems. KCE NY 26's system design in this application
depicts the footprint and equipment after all augmentation is completed throughout the project
life. To the extent possible, KCE will prepare the Proposed Action Site during initial
construction (e.g., grading, foundations, access roads, noise mitigation walls, etc.) in
anticipation of Project battery augmentation. The delivery and construction .during
augmentation phases will be coordinated with the Town of Southold.

1.7 Decommissioning
KCE creates a decommissioning plan -prior to project commissioning and is updated
throughout the Project's operational lifetime to adhere to current standards and take
advantage of new industry insights. The decommissioning plan considers:
1. Regulatory compliance, including all end-of-life equipment handling and any battery
recycling requirements;
2. On-site equipment and plan to decommission the facility;
3. Packaging and transport of batteries, specifically to ensure compliance with
hazardous material transport laws; and
4. Record retainment for final compliance.
Both pyrometallurgic and hydrometallurgic recycling options exist within the US today and will
be considered for all end-of-life batteries to reduce environmental impact.
An example Decommissioning Plan for a similar project has been included as Appendix C.

2.0 EXISTING CONDITIONS AND POTENTIAL IMPACTS ASSESSMENT
2.1 Natural Resources
This section assesses the potential for the Proposed Action.to impact natural resources on the
Proposed Action Site including wetland and water resources, threatened and endangered
species, critical environmental areas, and sensitive habitats. These findings are based on the
Natural Resources Report prepared by Land Use Ecological Services, .Inc. dated October 28,
2021, which is included as Appendix D. Natural resources were preliminarily screened by
utilizing spatial data and published natural resources .databases. including the NYSDEC
Environmental Resource Mapper (ERM), NYSDEC Tidal Wetland Inventory Maps, the
NYSDEC EAF Mapper, the NYS Natural Explorer, USFWS NWI Mapper and the USFWS iPac.
Subsequent to these preliminary screenings, field investigations were conducted on June 1,
2021, to confirm presence of potential natural resources on-site.
2.1.1 Wetlands and Water Resources
According to the NYSDEC Environmental Resource Mapper, the NYSDEC Tidal Wetlands
Inventory Maps and the UNFWS NW Mapper, no regulated wetlands or water resources were
identified on or adjacent to the Proposed Action Site.. The closest wetland,resource is located
approximately 0.50 miles north of the, Proposed Action Site. Further, a field inspection of the
property was conducted on June 1, 2021 and it was confirmed that no wetland/ surface water
resources, communities of wetland/ hydrophytic vegetation or indicators of wetland hydrology
were observed. Based on this, there are no potential significant adverse impacts to wetlands
or water resources anticipated.

. 2.1.2 Threatened and Endangered Species
Wildlife
The Proposed Action Site is in the vicinity of the potential presence of the Northern Long Eared
Bat (NLEB) which is listed at the federal and state levels as a threatened species. According to
records obtained from the New York Natural Heritage Program, there are two documented non-
winter locations of instances of the NLEB within 1.25 miles of the Proposed Action Site and bats
may travel 1.5 miles or more from documented locations. The main impact of concern with
respect to NLEB is the removal of potential roost trees.
Minimal tree removal is proposed as part of the Proposed Action and it is confined to two areas;
the first area is located in an overgrown field portion of the Site, within its southeastern section.
Trees here are generally sparse and shrubs and overgrown vegetation will also be removed.
The other area of minor tree removal tree is located at the Site access driveway which will be
subject to minimal realignment requiring small trees and shrubs be removed from this location.
In order to comply with NYSDEC guidance intended to minimize potential impacts to the NLEB,
all tree clearing on the property must be completed between December 1 — February 28. No
Article 11 (Incidental Take of Threatened/ Endangered Species) permit from the NYSDEC is
required for the project if all tree clearing can be accomplished between December 1 — February
28. It is anticipated that clearing will be confined to these timeframes.
There is a small-forested areas on the subject property, including a 2.0-acre forest patch on the
northeast portion which may provide suitable daytime roosting sites from NLEB due to the
presence of mature hardwood trees, such as oaks and hickories, with potential cavities and
exfoliating bark. However, no tree removal is proposed from this area and therefore no impacts
from that tree removal is anticipated.
Plant Species
Per the NY Nature Explorer, listed or protected species include Bushy Rockrose
(Crocanthemum dumosum, NYS- Threatened), Velvety Bush Clover (Lespedeza stuevei, NYS-
Threatened) Woodland Agrimony (Agrimonia rostellata, NYS Threatened). It should be noted
that, although these plants are listed as threatened in New York State, plant species on private
property are not protected from incidental take by the landowner, and therefore no Article 11
permit would be required from NYSDEC. Importantly, however, these species are not expected
to be impacted by the Proposed Action based on the following:
• Bushy Rockrose - A field investigation was conducted on June 1, 2021 to determine if
this species is present on the Proposed Action Site. Bushy rock rose_was not observed
on the,subject property.
• Velvety Bush Clover - this species is not expected to be present on the site as typical
habitat for this species is not present on the subject property, no Lespedezas or
common associates were observed during field investigations, and the existing record
for this species is from 1919.

Cutchogue,Town of Southold,New York
' Woodland Agrimony- this species is not expected to be present on the site as no
Agromonia sp. were observed on the subject property during field investigations and the
existing record for this species is from 1932.
Considering the lack of protected plant species or rare ecological communities, and that no
protected species were identified during the field survey, the Proposed Action does not
represent,a significant adverse impact to these resources.
2.1.3 Critical Environmental Areas and Sensitive Habitats
According to the NYSDEC EAF Mapper, the Site is not located on or adjacent to any Critical
Environmental Areas (CEAs). Further, according to the NYS Nature Explorer and USFWS
iPAC databases, there are no sensitive habitats present on, or within close proximity to the Site.
Based on this, there are no potential significant adverse impacts to CEAs of sensitive habitats
anticipated.
In conclusion, due to the lack of wetlands, water resources, CEAs and sensitive habitats on and
in the vicinity of the Site, and with the tree removal to occur within the NYSDEC established
timeframes, no significant adverse impacts to natural resources anticipated.

2.2 -- Noise
This section assesses the potential for noise impacts associated with the implementation of the
-` Proposed Action. These findings are based on the Noise Evaluation prepared by Acentech, Inc.
dated April 19, 2022, which is included as Appendix E. The assessment is based on the
following guidance documents: 1) the noise code of the Town of Southold, and 2) Assessing
_. and Mitigating Noise Impacts, a New York State Department of Environmental Conservation
(NYSDEC) guidance document(DEP-00-1).
The assessment utilized Cadna/A modeling software to calculate projected noise levels based
on operations of the Proposed Action.Site equipment and evaluated these at the Site property
line and nearby sensitive receptor locations.
2.2.1 Existing Conditions
Town of Southold
The Town of Southold noise ordinance.limits sound levels at the property line of the receiving
property based on the time of day, the sound source category, and the receiving property.

New York State
The NYSDEC guidance document, Assessing and Mitigating Noise Impacts, outlines thresholds
from noise changes resulting from projects subject to SEQRA. The document states that
increases from 0-3 dBA should have no appreciable effect on receptors, increases of 3-6 dBA
may have the potential for adverse impact only in cases where the most sensitive of receptors
are present, and increases of more than 6 dBA may require a closer analysis of the impact
potential depending on existing noise levels and the character of.surrounding land use and
receptors.
Background Ambient Noise Conditions
The guidance document suggests that one can assume a background sound level of 45 dBA for
a "quiet, seemingly serene setting" which would describe this project area. Qualitative
estimates were provided to assess the impact of the Proposed Action based on this assumed
ambient noise condition per the NYSDEC guidance. For this requirement, sound levels were
evaluated at the nearest residential abutters to KCE NY 26. Six residencies were identified
within the closest proximity to the Proposed Action Site. Figure 2.of Appendix E shows the
receptor locations.
2.2.2 Potential Impacts of the Proposed Action
- The Proposed Action contains several types of noise producing equipment including 272 battery
units, 17 inverters, one main power transformer and two HVAC units. The baseline design of the
BESS is surrounded fully to the west and partially to the north and south by sound barrier walls
that are 12 feet high above the ground. The sound barrier is shown in Figure 3 of Appendix E.
There is an opening for site access (-20 ft) to the west. It is assumed the opening will be
provided with a chain-link gate; for the assessment, this was modeled as an opening between
the two sides of the wall seen in Figure 3 of Appendix E.
The project only sound levels were calculated at each receptor which were combined with the
assumed ambient sound level of 45 dBA to estimate future sound levels with the Proposed.
Action in place. The increase over assumed ambient at the six residential receptor's locations
were also determined. See Table 3 for a summary of these.findings.

Figure 4 of, Appendix E shows the 50 to 85 dBA sound_ contours for night operation. As
presented in Table 2 above, the Town of Southold nighttime sound,limit is 50 dBA. It was-
calculated that the 50 dBA sound limit is expected to be exceeded at the property line however,
this excess is no more than 5 dB at the property line and the 50 dBA contour would not endure
more than 250 feet past the property line. This exceedance is for the nighttime only as
Proposed Action sound limits would be well under the daytime noise ordinance requirement of
65 dBA.
2.2.3 Conclusions
Project noise levels will not exceed the Town of Southold's nighttime residential noise limit of 50
dBA at neighboring residences; noise levels at these locations are expected to remain 4-5 dBA
below the nighttime code limit. Further, based on the assumed background sound level of 45
dBA, Proposed Action noise levels at residential receivers will only increase the sound levels at
a single nearby residential receiver by no more than 1 dBA. This falls into the NYSDEC
category wherein "No appreciable effects on receptors" is expected.
At the property line, it is expected that background noise levels would increase by 5 dBA, which
falls into the NYSDEC category of "may have potential for adverse noise impact only in cases
where the most sensitive of receptors are present." Given the agricultural use of land at this
property line, it is expected that the receptor is not in the "most sensitive" category, and
therefore adverse noise impacts are not expected.
Considering the above, no significant adverse impact to noise is anticipated.

2.3 Visual Resources
A visual assessment has been conducted to determine the potential for visual impacts
associated with the implementation of the Proposed Action. The assessment is based on the
guidance contained within the NYSDEC Visual Impact Assessment Methodology "Assessing
and Mitigating Visual Impacts" (DEP-00-2).
Four visual simulations have been prepared to present a conceptual view of conditions with the
Proposed Action in place. Visual simulations locations 1-3 were chosen at locations providing
the most direct views of the Proposed Action Site including the areas where the BESS Facility
would be located. Existing conditions photos and visual simulations are included in Appendix F.
Assessment of existing conditions and potential impacts of the Proposed Action at each visual
simulation location is discussed below.
2.3.1 Existing Conditions
The visual character of the Site is generally rural in nature, dominated by a large multi-acre
open views of farm fields containing generally flat topography. There is a mixed gravel/ dirt
access driveway in the vicinity of the Site's northeastern boundary. From Depot Lane the view
of the Site is of large open.fields containing grass and other crops and generally flat topography.
Vehicles and equipment stored on the northeastern area of the Site can also be observed from
Depot Lane. Large trees located on a parcel adjoining the Site to the southwest block the view
of the southeastern portion of the Site from Depot Lane. The Site is not currently visible from CR
48 which is the closest public vantage point to the southeast.
The visual character of the Proposed Action Site's immediate environs near its frontage with
Oregon Road is characterized by local roadways with low to moderate traffic, large lots, open
agricultural fields mixed with farmhouse style single-family residential homes, large storage
buildings and flat topography. Generally, land uses that occur within Y2 mile of the project site
primarily include agricultural, industrial, commercial and residential uses in addition to waste
management facilities.
State or Federal aesthetic resources in the vicinity of the Site include two properties that have
been determined by the State Historic Preservation Office (SHPO) as eligible for listing on the
National or State Register of Historic Places; these are located at 10426 and 10625 Oregon
Road directly to the west of the Site. There are no other State or Federally designated aesthetic
resources such as nation landmarks, parks, wildlife refuges, wild and scenic rivers, Scenic
Areas of Statewide Significance or National Heritage Areas within '/Z mile radius of the Site.
Locally important aesthetic resources within Y2 mile of the Site include CR 48 to the southeast;
CR 48 include views of the Atlantic Ocean, beaches and maritime life, and passes through a
series of wineries, expansive farms and wild wetlands. There is no publicly owned or operated
parkland, recreation area or designated open space on, or within % mile of the Site.
There are no public sidewalks accessing the Proposed Action Site. Views of the-Site are from,
private residential properties, agricultural land and industrial development in its immediate area.
Generally, views of the Site are expected to be transient in nature from Oregon Road and Depot
Lane drivers. These would include local residents and employees accessing homes and
businesses and visitors to the hamlet utilizing local roadways.

2.3.2 Potential Impacts of the Proposed Action
Four visual simulations were prepared for the locations described above to demonstrate
conceptual views of the Site with the Proposed Action in place. These locations were chosen to
demonstrate areas adjacent to the Proposed Action Site where views of the Proposed Action
will be most prominent. For visual simulations locations 1-3, the visual and sound barrier wall
("barrier"), plantings, building structures and electrical components associated with the
Proposed Action are simulated as part of this analysis.

Intersection Looking East
l Proposed Action Visual Simulation Location 1 (Simulation Location 1) shows that specific
Proposed Action features including electrical components (lightning masts, and an' A-frame
feeder breakers), landscaping, and the new 12"barrier wall.are visible modifications to the
Proposed Action Site from this vantage point. Other BESS facility components including the
battery modules enclosures, transformers, inverter units, control components of the new project
substation/ POI substation, the new control building, and the equipment enclosure are lower in
height than the barrier wall and landscaping and are not readily visible from Simulation Location
1
Hedgerow plantings are proposed around the barrier wall to serve as a visual buffer that fits with
IJ the area's surrounding context. A hedgerow typically consists of a mixed row of wild shrubs and
trees bordering a road or field. They often mark property boundaries as well as enclose or
separate areas with specific uses. The hedgerow planting will utilize large leafed deciduous
trees with strong branching character and broadleaf evergreen plantings for year-round effect.
IIn addition, as shown in Simulation Location 1, the height and color of the barrier wall appears
generally consistent with the initial landscaping to be installed.
The BESS Facility substantially exceeds the 100 foot minimum front yard setback requirements
in the existing zoning district by siting the facility approximately 1,138 feet from Oregon Road;
this substantial setback results in distant views of the lightening masts and A-frame from
Simulation Location 1, greatly reducing their visual prominence. Further, the southeastern
portion of the Site where-the new project substation and POI substation will be located is slightly
lower in elevation compared to the northwestern portion of the Site, further diminishing the
prominence of the project/ POI substations' electrical components from this vantage point. The
multi-acre grassed and open field that is currently prominent on-site is expected to remain,
contributing to the consistency of the Proposed Action with existing visual conditions. Due to the
extensive set back distance from public viewpoints; addition of a barrier wall to enclose the
BESS and appurtenant structures,, the installation of new plantings, and the continued
' prominence of open vistas on the Site, the Proposed Action is not expected to result in a
significant adverse impact to visual conditions when compared to the existing conditions at

Simulation Location 2a shows that specific Proposed Action features including electrical
components (lightning masts, A-frame feeder breakers, utility poles and transmission lines),
landscaping, and the new 12" barrier wall are visible modifications to the Proposed Action Site
1 from this vantage point. Other. BESS facility components including the battery modules
enclosures, transformers, inverter units, control components of the new project substation/ POI
substation, the new control building, and the equipment enclosure are lower in height than the
barrier wall and landscaping and are not.readily visible from Simulation Location 2a.
- Hedgerow planting is proposed as a visual buffer that fits with the area's surrounding context,
and will utilize large leafed deciduous trees with strong branching character and broadleaf
evergreen plantings for year-round effect. As discussed above, Simulation Location 2a depicts
_ the proposed landscaping with leaf-on conditions which is representative of the view of the Site
during late spring, summer and early fall months. The height and color of the barrier wall
appears generally consistent with the initial supplemental landscaping to be installed. Both the
inclusion of new landscaping and new barrier wall will provide visual screening. Due to the
siting of the BESS with substantial setbacks to public vantage points views of the Proposed
Action features from Simulation Location 2a are distant, reducing their contrast to the
surrounding context. The multi-acre grassed and open field that is currently prominent on-site is
expected to remain, contributing to the consistency of the Proposed Action with existing visual
conditions from this vantage_point.
Simulation Location 2b
Similar to Simulation Location 2a, Simulation Location 2b shows that specific Proposed Action
features including electrical components (lightning masts, A-frame feeder breakers, utility poles
and transmission lines), landscaping, and the new 12" barrier wall are visible modifications to
the Proposed Action Site from this vantage point. Other BESS facility components including the
battery modules enclosures, transformers, inverter units, control components of the new project
substation/ POI substation, the new control building, and the equipment enclosure are lower in
height than the barrier wall and landscaping and are not readily visible from Simulation Location
2b.
Hedgerow planting is proposed as a visual buffer that fits with the area's surrounding context,
and will utilize large leafed deciduous trees with strong branching character and broadleaf
evergreen plantings for year-round effect. As discussed above, Simulation Location 2b depicts
the proposed landscaping with leaf-off conditions which is representative of the view of the Site
during winter, early spring and late fall months. In comparison to Simulation Location 2a,
Simulation Location- 2b shows that leaf-off conditions results in ra more obvious view of the
barrier wall. However, even with leaf-off conditions, the inclusion of new landscaping and new
barrier wall will provide visual.screening.

Due to the extensive set back distance from public viewpoints, addition of a barrier wall to
enclose the BESS and appurtenant structures, the installation of new plantings, and the
continued prominence of open vistas on the Site, the Proposed Action does not represent a
significant adverse impact to visual conditions when compared to the existing conditions at
Location 2 either in leaf-on or leaf-off conditions. .
Proposed Action Visual Simulation Location 3: View from Depot Lane Looking Northeast
Proposed Action-Visual Simulation Location 3 .(Simulation Location 3) shows that specific
Proposed Action features including' one lightning mast, landscaping, and the new 12" barrier
wall are visible modifications to the Proposed Action Site from this vantage point. The
northeastern portion of the Site is higher in grade compared to the southwestern portion of the
Site; due to these differences in grade, BESS facility components including the tops of battery
module enclosures located towards the northeastern portion of the Site are slightly visible from
this vantage point.
As discussed above, hedgerow planting is proposed as a visual buffer that fits with the area's
surrounding context and will utilize large leafed deciduous trees with strong branching character
and broadleaf evergreen plantings for year-round effect.' The height and color of the barrier wall
appears generally consistent with the initial supplemental landscaping to.be installed. The
BESS facility exceeds the 20-foot minimum. side yard setback requirements in the existing
zoning district by siting the facility approximately 69 feet from the Site's southwestern property
line and greater than 1,000 feet from Depot Lane; this substantial setback results in distant
views of the lightening mast and battery modules'enclosures, greatly reducing their visual
prominence.
Other proposed structures including additional lighting.masts, A-frame feeder breakers, utility
poles and transmission lines, the new control building, and the equipment enclosure will not be
visible from this vantage point as they are sited on the southeastern portion of the Site which is
lower in grade compared to other areas of the Site. In addition, large trees located on a parcel

existing trees to remain, and the continued prominence of open vistas on the. Site, the
Proposed Action does not represent a significant adverse impact to visual conditions when
compared to the existing conditions at Visual Simulation Location 3.
In addition to Visual Simulation Locations 1-3, a transmission line through a utility easement
requested on the adjacent property to the southeast is also proposed to be constructed8.
Approximately 13 utility poles are planned for installation through the easement, two of which
likely would be installed on CR 48. Each pole will span 150-180 feet through the easement; the
ground surface elevation through the easement is approximately 15-25 feet below CR 48
existing grade and therefore, this would diminish the visual prominence of the transmission line
through the easement from CR 48. Utility poles associated with the transmission line on CR48
are expected to be at heights consistent with LIPA's existing transmission infrastructure there,
(approximately 50-70-ft), however, the designs for this infrastructure are not available at this
time. As discussed above in Section 1.1, LIPA will have the final determination over the design
and implementation of the transmission line and associated infrastructure and will determine
construction materials, heights and construction methods.
In conclusion, although the Proposed Action will be visible from public vantage points
surrounding the Site.this is not expected to result in a significant adverse impact to visual
resources. As shown in the simulations and due to the many design features incorporated into
the project to minimize potential visual impacts including extensive set back distance from
public viewpoints, the siting of electrical components on south easternmost portion of the Site
closest to other industrial uses, addition of a barrier wall to enclose the BESS and appurtenant
structures, and installation of new plantings and the consistency of proposed utility pole and line
infrastructure, the Proposed Action will expected to be aesthetically compatible with the
surrounding environment.
a At this time, utility pole and transmission line final design has not been completed by PSEG LI and
therefore, specific heights and materials of these utility features cannot be known. For the purposes of
this assessment,the utility poles are assumed to be constructed at heights consistent with existing utility
infrastructure on CR 48 where they will connect to the existing utility poles and the transmission line
currently located on that right-of-way.

2.4 Local Waterfront Revitalization Program (LWRP)
In accordance with Town of Southold Local Waterfront Revitalization Program (LWRP), a
Coastal Assessment Form (CAF) and accompanying supplement have been prepared. These
documents are included in Appendix B and support the Proposed Action's consistency with the
applicable LWPR policies.
2.5 Stormwater
Construction activities that result in greater than or equal to. 1 acre of land disturbance must
comply with the requirements of the NYSDEC State Pollutant Discharge Elimination System
(SPDES) General Permit for Stormwater Discharges from Construction Activity (GP-0-20-001 or
General Permit). As discussed above in section 1.1, a total of approximately 11.00 acres of land
disturbance is anticipated to occur during construction activities under the Proposed Action. In
consideration of this, KCE will prepare a Stormwater Pollution Prevention Plan (SWPPP)
compliant with the General Permit and Chapter 236 of the Town of Southold Code and submit a
Notice of Intent (NOI) to the NYSDEC. . Further, a Stormwater Management Control Plan
(SMCP) for the construction activity will be prepared and submitted to the Town's Stormwater
Management Officer per Chapter 236 of the Town Code.
Two weekly SWPPP inspections will be required under GP-0-20-001 during the construction
phase of this project and will help to ensure that erosion and sedimentation controls are
functioning as designed to minimize the potential for significant adverse impacts from
stormwater runoff during construction. To manage post construction stormwater flows from the
BESS Facility, a system of catch basins and drywells is proposed.' Catch basins located
throughout the development will capture runoff and convey stormwater to drywells designed to
infiltrate stormwater into the subsurface soils, thus preventing off-site transport of stormwater
runoff for the design storm. It should be noted that the catch basins proposed on the upstream
end of the stormwater management systems will be provided with sumps that will capture larger
debris, preventing debris build-up within the drywells that could diminish the infiltration capacity
of these features. Dry wells are green infrastructure practices that provide infiltration of
stormwater and may be used to satisfy the treatment objectives required per NYSDEC
guidance. The drywell system would.be designed to exceed the Town of Southold standard for
management of a 2-inch design storm event.
The stormwater management system has been designed to meet the sizing criteria of the New
York State Stormwater Management Design Manual, including Water Quality Volume (WQV),
Runoff Reduction Volume (RRv), Channel Protection Volume (Cpv), Overbank Flood control
(Qp) and Extreme Storm control (Qf) sizing criteria. Utilization of infiltration practices (drywells)
emulates natural stormwater runoff mitigation by allowing stormwater to infiltrate into on-site
soils. The hydrology and hydraulics of the development site and stormwater management
practices have been modeled to demonstrate no net increase in stormwater runoff leaving the
developed project site when comparing pre and post construction conditions, thereby
demonstrating compliance with Stormwater Management Design Manual Qp and Qf sizing
criteria.
The Proposed Action would include presence of chemicals and its design incorporates several
features to mitigate potential discharges of these chemicals to the environment. Specifically, a
total of + /- 22,455 gallons of dielectric/ cooling fluid.for the transformers and +/- 70,176 kg of
lithium-ion fluid encased within the BESS. The dielectric/ cooling fluid'will arrive pre-sealed in
the medium voltage and main transformers and the lithium-ion fluids will be pre-sealed within
22
KCE NY 26 Proposed BESS Project Expanded Environmental Assessment
Cutchogue,Town of Southold,New York
each individual battery unit within the containers. Chemicals on-site will not be diminished
during operations or require replenishment. In addition, the battery enclosures, transformers and
the project and POI substation equipment will be installed on concrete foundations; these on-
grade concrete pads will minimize the potential for infiltration into impervious surfaces or
transport via, stormwater runoff. In addition, detailed design of the Proposed Action is not
currently completed, however, as this proceeds, it is expected that secondary containment for
the main power transformer and medium voltage transformers fluids will be designed and.
implemented.
With the implementation of a SWPPP that would manage construction and post construction
flows and design elements which mitigate potential discharges of chemicals to the environment
including concrete foundations and secondary containment, no potential significant adverse
impact to stormwater is anticipated.
2.6 Cultural Resources
According to the SHPO Cultural Resources.Information System (CRIS), the Proposed Action is
not located within districts or structures that are listed on the National or State Register of
Historic Places or sites that have been determined to be eligible for the National or State
Register. As part of SHPO's review of the Proposed Action, they have determined structures in
proximity to the Site including, B.H. Corwin House at 10425 Oregon Road, and the Water
Tower / Tank house at 10625 Oregon Road, are eligible for listing on the National or State
Register of Historic Places. According to CRIS, the B.H. Corwin House is eligible for listing
under Criterion C in the area of architecture as a rare example of a nineteenth century
vernacular saltbox farmhouse, and Water Tower/ Tank house is eligible for listing under
Criterion A in the area of agriculture as an example of the regional pattern of water tower and
tank house construction on the North Fork of Long Island.
The BESS Facility features are set back more than 1,000 feet from the Site's frontage with
Oregon Road where these properties are located diminishing the BESS Facility prominence
from those locations. The visual barrier wall and landscaped vegetated buffer further diminish
the BESS Facility prominence from these historic resources. Visual simulations have been
prepared to illustrate the BESS Facility's finished appearance and these are presented in
Appendix F and discussed in Section 2.3. Simulation Location 2 is located between these
historic resources and demonstrates that the view of the facility would not be intrusive at these
properties.
The Town of Southold also has extensive locally designed historic resources. According to
Figure 5.1 Cultural Resources Map in the Town of Southold's Comprehensive Plan (provided as
Figure 4 below), the Proposed Action Site does not contain cultural resources designated by the
Town such as lighthouses, significant trees, mile markers, cemeteries, museums, state/ national
historic register districts and/ or properties, or land inventoried by the Society for the
Preservation of Long Island Antiquities (SPLIA). One property adjoining the Site to the
southwest and one property adjoining the Site to the northwest are inventoried by SPLIA as
historic structures of regional importance. SPLIA is a 501c3 not-for-profit organization
committed to preserving Long Island's cultural and architectural heritage through advocacy,
education, and stewardship of historic sites and collections.

The property adjoining the Site to the southwest currently contains agricultural uses including a
residential structure and agricultural storage facilities and is zoned Light Industrial Park/Planned
Office Park District (LIO). The property adjoining the Site to the northwest currently contains
residential uses on Oregon Road's frontage, with agricultural uses towards the rear of the
property and is zoned Agricultural Conservation District (AC). Considering the adjoining property
to the southwest is zoned LIO and a visual barrier wall and landscaped vegetated buffer will be
installed, the view of the BESS facility is not expected to be intrusive at this property (see
Proposed Action Visual Simulation Location 3: View from Depot Lane Looking Northeast in
Appendix F for reference). As discussed in Section 2.3, the BESS Facility substantially exceeds
the setback requirements in the existing zoning district by siting the facility approximately 1,138
feet from Oregon Road. Considering the property adjoining the Site to the northwest that is
inventoried by the SPLIA will be over 1,138 feet away from the BESS structures and a visual
barrier wall and landscaped vegetated buffer will be installed, the view of the BESS facility is
also not expected to be intrusive at this property.
According to CRIS, the Proposed Action is not within an area designated as a buffer area
sensitive for archaeological sites on the SHPO archeological site inventory. SHPO is currently
reviewing the Proposed Action and has not indicated that the potential for archaeological
resources requires study.
In consideration of the above, no potential significant adverse impacts are anticipated to
historic or archeological resources from the Proposed Action.

APPENDIX B-Coastal Assessment Form Supplement
Page 1 of 10
This supplemental document includes assessment of the Town of Southold Local Waterfront Revitalization
Program (LWRP), specifically, the policies and policy standards set forth in Section III Waterfront
Revitalization Policies (LWRP Policies)'. The subject property lies within Reach 2 of the Reach areas
defined within the LWRP. Where the LWRP policy is applicable, an assessment supporting the Proposed
Action's consistency with the policy and applicable policy standards is presented.
DEVELOPED COAST POLICY
Policy 1. Foster a pattern of development in the Town of Southold that enhances community
character, preserves open space, makes efficient use of infrastructure, makes Beneficial use of a
coastal location, and minimizes adverse effects of development. See LWRP Section III — Policies;
Page 2 for evaluation criteria.
The Proposed Action is consistent with land use patterns in the area and would not result in a loss of the
community and landscape character in the Town of Southold.The site is presently zoned LI, Light Industrial
(see Expanded EA Figure 3, Cutchogue Zoning)and the proposed use is permitted in this district by Special
Exception of the Board of Appeals.The Proposed Action Site is 27.04 acres and approximately 16.04 acres
will remain undeveloped, preserving views of vast flat vegetated areas visible from local roadways. The
Proposed Action makes efficient use of existing infrastructure through connection to LIPA transmission
infrastructure located on CR 48; this LIPA transmission infrastructure is sized to accommodate energy
contributions of a utility scale BESS system. The Proposed Action will contribute to the minimization of
adverse impacts of developments through its contributions to meeting statewide energy storage goals, and
its preparation of the grid to accommodate expected offshore clean energy from wind generation and
retirements of existing fossil fuel peaker plants.
Policy 2. Protect and preserve historic and archaeological resources of the Town of Southold. See
LWRP Section III—Policies Pages 3 through 6 for evaluation criteria
2.1 Maximize preservation and retention of historic resources.
The Proposed Action does not propose work within districts or structures that are listed on the National or
State Register of Historic Places or sites that have been determined to be eligible for the National or State
Register according to the State Historic Preservation Office(SHPO)Cultural Resources Information System
(CRIS). As part of its review of the Proposed Action, SHPO has determined structures in proximity to the
Site, B.H. Corwin House at 10425 Oregon Road, and the Water Tower/ Tank house at 10625 Oregon
Road, are eligible for listing on the National or State Register of Historic Places. The BESS Facility features
are set back more than 1,000 feet from the Site's frontage with Oregon Road where these properties are
located diminishing the BESS Facility prominence from those locations. The visual barrier wall and
landscaped vegetated buffer further diminish the BESS Facility prominence from these historic resources.
Visual simulations have been prepared to illustrate the BESS Facility's finished appearance and these are
presented in the Expanded Environmental Assessment (EA); Proposed Action Visual Simulation Location
2: View from Oregon Road Looking Southeast is located between these historic resources and
demonstrates that the view of the facility would not be intrusive at these properties (see Section 2.3.3 of
the Expanded EA).
The Town of Southold also has extensive locally designed historic resources.As discussed in the Expanded
EA; according to Figure 5.1 Cultural Resources Map in the Town of Southold's Comprehensive Plan
(provided as Figure 4 in the Expanded EA), the Proposed Action Site does not contain cultural resources
designated by the Town such as lighthouses, significant trees, mile markers, cemeteries, museums, state/

national historic register districts and/or properties, or land inventoried by the Society for the Preservation
of Long Island Antiquities (SPLIA). One property adjoining the Site to the southwest and one property
adjoining the Site to the northwest are inventoried by SPLIA as historic structures of regional importance.
SPLIA is a 501c3 not-for-profit organization committed to preserving Long Island's cultural and architectural
heritage through advocacy, education, and stewardship of historic sites and collections. The property
adjoining the Site to the southwest currently contains agricultural uses including a residential structure and
agricultural storage facilities and is zoned Light Industrial Park/Planned Office Park District (LIO). The
property adjoining the Site to the northwest currently contains residential uses on Oregon Road's frontage,
with agricultural uses towards the rear of the property and is zoned Agricultural Conservation District(AC).
Considering the adjoining property to the southwest is zoned LIO and a visual barrier wall and landscaped
vegetated bufferwill be installed,the view of the BESS facility is not expected to be intrusive atthis property.
As discussed in Section 2.3 of the Expanded EA, the BESS Facility substantially exceeds the setback
requirements in the existing zoning district by siting the facility approximately 1,138 feet from Oregon Road.
Considering the property adjoining the Site to the northwest that is inventoried by the SPLIA will be over
1,138 feet away from the BESS structures and a visual barrier wall and landscaped vegetated buffer will
be installed, the view of the BESS facility is also not expected to be intrusive at this property.
2.2 Protect and preserve archaeological resources.
The Proposed Action is not within an area designated as a buffer area sensitive for archaeological sites on
the SHPO archeological site inventory. SHPO is currently reviewing the Proposed Action and has not
indicated that the potential for archaeological resources requires study.
Policy Standard 2.3 is not applicable to the Proposed Action as it does not impact resources that are
significant to the coastal culture of the Long Island Sound.
Policy 3. Enhance visual quality and protect scenic resources throughout the Town of Southold.
See LWRP Section III—Policies Pages 6 through 7 for evaluation criteria
3.1 Enhance visual quality and protect scenic resources throughout the Town of Southold.
The Proposed Action is consistent with the applicable aspects of this Policy Standard (Sections A-E)in that
it minimizes the potential for the BESS to be discordant with the existing visual character of the area.
Several approaches have been used to preserve.visual character including; siting of the BESS Facility on
a large site set back a considerable distance from most direct public vantage points; use of an approximately
12 feet tall visual barrier wall to reduce prominence of BESS Facility features; incorporation of vegetative
hedgerow buffers around the BESS Facility's perimeter; and preservation of existing vegetation where
possible including 2.0 acres of forested area in the northeastern portion of the site and the preservation of
a multi-acre grassed/o.pen field area between the BESS Facility and the Site's frontage with Oregon Road.
Setback distances required by the zoning of the Site will also be complied with. Specifically, the BESS
Facility substantially exceeds the 100-foot minimum front yard setback and 20-foot minimum side yard
setback requirements in the existing zoning district by siting the facility approximately 1,138 feet from
Oregon Road and 69 feet from the Site's southwestern property line. The facility is also greater than 1,000
feet from Depot Lane.These substantial set back distances, combined with the large area of the Site to be
undisturbed to preserve views consistent with the area's context, ample landscaping and visual barrier,
support the Proposed Action's aesthetic compatibility with existing conditions.
Visual simulations have been prepared and are included in the Expanded EA Section 2.3 attached to this
application. As shown in that assessment, the setback from public vantage points greatly diminishes the
prominence of the BESS from Oregon Road and Depot Lane. Elements of the Proposed Action from
Oregon Lane will be visible including the 12-foot high visual barrier wall, landscaping and lightning masts
approximately 55.7 feet in height. Elements of the Proposed'Action visible from Depot Lane include the 12-
foot high visual barrier wall, landscaping and one lightning mast in addition to minimal views of the tops of
battery module enclosures; the visual barrier wall and landscaping provide screening to the BESS Facility.
To screen the facility's barrier wall's visual impacts, a hedgerow planting is proposed as a visual buffer that
fits with the area's surrounding context. A hedgerow typically consists of a mixed row of wild shrubs and
KCE NY 26 Proposed BESS Project
APPENDIX B-Coastal Assessment Form Supplement
Page 3of10
trees bordering a road or field. They often mark property boundaries as well as enclose or separate areas
with specific uses. The hedgerow planting will utilize large leafed deciduous trees with strong branching
character and broadleaf evergreen plantings for year-round effect.
A transmission line through a utility easement requested on the adjacent property to the southeast is also
proposed to be constructed3. Approximately 13 utility poles are planned for installation through the
easement, two of which likely would be installed on CR 48. Each pole will span 150-180 feet through the
easement; the ground surface elevation through the easement is approximately 15-25 feet below CR48
existing grade and therefore,this would diminish the visual prominence of the transmission line through the
easement from CR48. Utility poles associated with the transmission line on CR48 are expected to be at
heights consistent with the Long Island Power Authority's existing transmission infrastructure there,
(approximately 50-70-ft), however, the designs for this infrastructure are not available at this time. As
discussed above in Section 1.1 of the Expanded EA, LIPA will have the final determination over the design
and implementation of the transmission line and associated infrastructure and will determine construction
materials, heights and construction methods.
According to the LWRP Policies, CR48 is a scenically important county road offering open views of farms
and woodland which the Town of Southold promotes the protection of through a Scenic Byway Corridor
Management Plan (2001). CR 48 is a scenic resource also referred to as the North Fork Trail Scenic Byway
by the NYSDOT and is listed on the New York State Department of Transportation (NYSDOT) Scenic
Byways List. As discussed, however, CR 48 contains an established transmission line with utility poles of
similar height to that which is proposed. With the removal of one currently existing pole,the addition of two
poles is not expected to be a stark contrast to the character of this scenic road,which already contains this
a transmission line and utility pole infrastructure.
The preservation of large open areas, extensive set back distance from public viewpoints,the visual barrier
wall and plantings, and the consistency of proposed utility pole and line infrastructure with existing facilities
all contribute to the protection of scenic resources and support the Proposed Action's aesthetic compatibility
with the surrounding area and its consistent with this policy.
Policy Standard 3.1 items F- J are not applicable to the Proposed Action as it would not impact the
Cutchogue hamlet center, historic maritime areas,water dependent uses or public lands.
The Proposed Action is consistent with Policy Standard 3.1 item K in that it does not detract from the visual
quality associated with agricultural land, open space and natural resources. As discussed above, the
Proposed Action includes introduction of a visual barrier wall and vegetated landscaping buffer that will
diminish its prominence from public vantage points. The Proposed Action will utilize 11.00 acres of a 27.04
acre Site;this is an efficient design that preserves views of existing open vegetated areas and is consistent
with the surrounding visual'setting on Oregon Road. The Proposed Action Site is surrounded on its
northeastern, eastern and southeastern sides by land utilized by the Town for waste handling and
management and these uses would not be sensitive to the change in view that the BESS facility represents.
The Proposed Action does not include intrusive light sources; exterior lighting will be limited to lights
required for security and emergency situations/nighttime repairs; nighttime lighting is only expected during
times of nighttime emergency repairs. All lighting will comply with applicable Town regulations including
considerations to prevent excessive lighting, energy waste, glare, light trespass, and unnecessary skyglow.
s At this time,utility pole and transmission line final design has not been completed by PSEG LI and therefore,specific heights and
materials of these utility features cannot be known.For the purposes of this assessment,the utility poles are assumed to be
constructed at heights consistent with existing utility infrastructure on CR48 where they will connect to the existing utility poles and
the transmission line currently located on that right-of-way.

NATURAL COAST POLICIES
Policy 4. Minimize loss of life, structures, and natural resources from flooding and erosion. See
LWRP Section III-Policies Pages 8 through 16 for evaluation criteria
This policy is not applicable. The Proposed Action does not propose or impact erosion control structures
and is not located directly along a coastline
Policy 5. Protect and improve water quality and supply in the Town of Southold.See LWRP Section
III—Policies Pages 16 through 21 for evaluation criteria
Policy 5.1 is not applicable. The Proposed Action does not introduce nitrogen discharges, new wastewater
treatment system, point source discharges or require treatment of sanitary sewer or industrial discharges.
5.2 Minimize non-point pollution of coastal waters and manage activities causing nonpoint
pollution.
Policy Standard 5.2 includes objectives to address non-point source pollution and the Proposed Action is
compliant with this policy. The Proposed Action would include.preparation of a.Stormwater Pollution
Prevention Plan (SWPPP) including soil erosion and sediment control measures designed in accordance
with the SPDES General Permit for Stormwater Discharges from Construction Activities (GP-0-20-001).
Two weekly SWPPP inspections will be required under Permit No. GP-0-20-001 during the construction
phase of this project and will help to ensure that erosion and sedimentation controls are functioning as
designed to minimize the potential for significance adverse impacts from stormwater runoff during
construction.
As discussed, the BESS Facility will disturb 11.00 acres of the 27.04 Site; this is an efficient design that
maintains large swaths of undeveloped and vegetated areas that currently exist on-site. To manage post
construction stormwater flows from the BESS Facility, a system of catch basins and drywells is
proposed. Catch basins located throughout the development will capture runoff and convey stormwater to
drywells designed to infiltrate stormwater into the subsurface soils, thus preventing off-site transport of
stormwater runoff for the design storm. It should be noted that the catch basins proposed on the upstream
end of the stormwater management systems will be provided with sumps that will capture larger debris,
preventing debris build-up within the drywells that could diminish the infiltration capacity of these features.
Dry wells are green infrastructure practices that provide infiltration of stormwater and may be used to satisfy
the treatment objectives required per NYSDEC guidance.The drywell system would be designed to exceed
the Town of Southold standard for management of a 2-inch design storm event.
The stormwater management system has been designed to meet the sizing criteria of the New York State
Stormwater Management Design Manual, including Water Quality Volume (WQV), Runoff Reduction
Volume(RRv), Channel Protection Volume(Cpv), Overbank Flood control(Qp)and Extreme Storm control
(Qf)sizing criteria.Utilization of infiltration practices(drywells)emulates natural stormwater runoff mitigation
by allowing stormwater to infiltrate into on-site soils. The hydrology and hydraulics of the development site
and stormwater management practices have been modeled to demonstrate no net increase in stormwater
runoff leaving the developed project site when comparing pre and post construction conditions, thereby
demonstrating compliance with Stormwater Management Design Manual Qp and Qf sizing criteria.
The Proposed Action would include presence of chemicals and its design incorporates several features to
mitigate potential discharges of these chemicals to the environment. Specifically, a total of + /- 22,455
gallons of dielectric/cooling fluid for the transformers and +/-70,176 kg of lithium-ion fluid encased within
the BESS would be located on-site. The dielectric/ cooling fluid will arrive pre-sealed in the transformers
and the lithium-ion fluids will be pre-sealed within each individual battery unit within the containers.
Chemicals on-site will not be diminished during operations or requirement replenishment. In addition, the
battery enclosures,transformers and the project and POI substation equipment will be installed on concrete

APPENDIX B-Coastal Assessment Form Supplement
Page 5 of 10
foundations;these on-grade concrete pads will minimize the potential for infiltration into impervious surfaces
or transport via stormwater runoff. In addition, detailed design of the Proposed Action.is not currently
completed, however, as this proceeds, it is expected that secondary containment for the main power
transformer and medium voltage transformers fluids will be designed and implemented.
With the implementation of a SWPPP that would manage construction and post construction flows and
design elements which mitigate potential discharges of chemicals to the environment including concrete
foundations and secondary containment, no potential significant adverse impact to water quality are
anticipated and the Proposed Action is consistent with this policy.
Policy Standards 5.3 is not applicable to the project; Policy Standard 5.3 focuses on quality of coastal
waters which would not be adversely impacted by the Proposed Action as no coastal discharges or other
infringement into coastal resources is proposed. Minimization of potential impacts from stormwater runoff
is discussed in the assessment for Policy Standard 5.2.
5.4 Limit the potential for adverse impacts of watershed development on water quality
and quantity,
Policy Standard 5.4 discusses protection and conservation of the quality and quantity of potable water.The
Proposed Action Site is not located within the Special Groundwater Protection Area within the Town4 and
includes measures to allow for infiltration of stormwater on-site with appropriate considerations for
minimization of pollutants as discussed in the assessment for Policy Standard 5.2.
5.5 Protect and conserve the quality and quantity of potable water.
As referenced in the assessment provided for Policy Standard 5.2, the Proposed Action would minimize
the potential for contamination of potable waters by implementation of a drywell infiltration system that
includes measures to minimize discharge of pollutants to groundwater. The Proposed Action is not within
the Special Groundwater Protection Area within the Town and therefore is not expected to significantly
impact areas of special import to replenishment of potable groundwater supplies.
Policy 6.Protect and restore the quality and function of the Town of Southold ecosystems including
Significant Coastal Fish and Wildlife Habitats and wetlands.See LWRP Section III—Policies; Pages
22 through 32 for evaluation criteria.
Policy Standards 6.1-6.3 are not applicable to the Proposed Action as it does not include adverse changes
to the Long Island Sound and the Peconic Bay ecosystems, disruptions to ecological quality or impacts to
Significant Coastal Fish and Wildlife Habitats. There are no tidal or freshwater wetlands or rare ecological
communities present on-site according to the NYS Environmental Resource Mapper, NYS Tidal Wetlands
Inventory Maps, and NYS EAF Mapper, respectively (See Expanded EA Appendix C Natural Resources
Report for additional details).
6.4 Protect vulnerable fish,wildlife, and plant species, and rare ecological communities.
Wildlife
The Proposed Action Site is in the vicinity of the potential presence of the Northern Long Eared Bat(NLEB)
- which is listed at the federal and state levels as a threatened species. According to records obtained from
the New York Natural Heritage Program, there are two documented non-winter locations of instances of
the NLEB within 1.25 miles of the Proposed Action Site and bats may travel 1.5 miles or more from
4 NYSDEC Info Locator.Accessed February 2022. DECinfo Locator(ny.gov)
KCE NY 26 Proposed BESS Project
APPENDIX B-Coastal Assessment Form Supplement
Page 6 of 10
documented locations. The main impact of concern with respect to NLEB is the removal of potential roost
trees.
Minimal tree removal is proposed as part of the Proposed Action and it is confined to two areas; the first
area is located in an overgrown field portion of the Site, within its southeastern section. Trees here are
generally sparse. Shrub and overgrown vegetation will also be removed. The other area of minor tree
removal tree is located at the Site access driveway which will be subject to minimal realignment requiring
small trees and shrubs be removed from this location. In order to comply with NYSDEC guidance intended
to minimize potential impacts to the NLEB, all tree clearing on the property must be completed between
December 1 — February 28. No Article 11 (Incidental Take of Threatened/ Endangered Species) permit
from the NYSDEC is required for the project if all tree clearing can be accomplished between December 1
—February 28. It is anticipated that clearing will be confined to these timeframes.
There is a small-forested areas-on the subject property, including a 2.0-acre forest patch on the northeast
portion which, may provide suitable daytime roosting sites from NLEB due to the presence of mature
hardwood trees, such as oaks and hickories, with potential cavities and exfoliating bark. However, no tree
removal is proposed from this area and therefore no impacts from that tree removal is anticipated.
Considering the small amount of tree removal proposed and the adherence to NYSDEC imposed clearing
timeframes, the Proposed Action would not represent a significant impact to vulnerable wildlife populations
and is therefore consistent with this policy.
The USFWS iPAC was also reviewed for additional potential threatened and endangered species. The
PAC database is not site specific, but rather county specific. According to the USFWS iPAC database
threatened and endangered species in Suffolk County include the Piping plover (Threatened), Red knot
(Threatened), Roseate tern (Endangered), Sandplain gerardia (Endangered), and Seabeach amaranth
(Threatened). However, these species inhabit beach and shoreline/wetland habitats which are not found
on the Proposed Action Site.
Additionally, the USFWS iPAC report indicates a total of 12 bird species that are protected under the
Migratory Bird Treaty Act and/or Bald and Golden Eagle Protection Act that may inhabit or utilize the Site
for breeding. The potential presence of bird species protected under the Migratory Bird Treaty Act does
not impose any regulatory constraints on the development and none of the migratory bird species listed
on the iPAC report are expected to utilize the subject property during breeding or migratory seasons.
Plant Species
Per the NY Nature Explorer, listed or protected species include Bushy Rockrose (Crocanthemum
dumosum, NYS- Threatened), Velvety Bush Clover (Lespedeza stuevei, NYS-Threatened), Woodland
Agrimony(Agrimonia rostellata, NYS Threatened). It should be noted that, although these plants are listed
as threatened in New York State, plant species on private property are not protected from incidental take
by the landowner, and therefore no Article 11 permit would be required from NYSDEC. Importantly,
however, these species are not expected to be impacted by the Proposed Action based on the following:
• Bushy Rockrose-A field investigation was conducted on June 1, 2021 to determine if this species
is present on the Proposed Action Site. Bushy rock rose was not observed on the subject property.
• Velvety Bush Clover-this species is not expected to be present on the site as typical habitat for
this species is not present on the subject property, no Lespedezas or common associates were
observed during the field investigation, and the existing record for this species is from 1919.
• Woodland Agrimony-this species is not expected to be present on the site as no Agromonia sp.
were observed on the subject property during the field investigation and the existing record for this
species is from 1932.
Considering the lack of protected plant species or rare ecological communities, the Proposed Action does
not represent a significant adverse impact to these resources and is consistent with this policy.

Policy 7. Protect and improve air quality in the Town of Southold. See LWRP Section III —Policies
Pages 32 through 34 for evaluation criteria.
7.1 Control or abate existing and prevent new air pollution.
Policy 7 acknowledges that the most likely source of air pollution to the Town would be from expansion or
creation of new power generation plants and automobile use. The Proposed Action supports the protection
of air quality and the transition to cleaner energy. The BESS Facility is not a source of air emissions. In
addition, KCE NY 26 will support the Public Service Commission's Order Establishing Energy Storage Goal
and Deployment Policy, which outlines statewide energy storage deployment goals of 1,500 MW by 2025
and 3,000 MW by 20305. In October 2020, Strategen Consulting LLC prepared the Long Island Fossil
Peaker Replacement Study for Newyork Battery and Energy Storage Technology Consortium(NY-BEST)6.
The study examined operations of Long Island's aging fossil-fueled power plants that operate primarily
during peak times, and found that it is feasible and cost-effective to replace more than 2,300 MW of Long
_- Island's 4,300 MW fossil-fueled peaker plants with energy storage'over the next decade. It also found that
approximately half of the peaker plants, around 1;100 MW, could be retired and replaced,with energy
storage by 2023.The remaining 1,200 MW could be replaced by 2030, in conjunction with New York State's
plans to increase solar energy, energy efficiency measures, and offshore wind resources. Over the next
decade,fossil peaker replacements could .also save LIPA customers as much as$393 million and
contribute to significantly reducing harmful air pollutants.
The BESS will be remotely monitored and will operate generally unmanned. It is not expected to generate
significant traffic that would be the source of mobile air emissions. The Proposed Action is therefore
J consistent with this policy.
Policy Standards 7.2 and 7.3 are not applicable to the Proposed Action'as it does not propose discharges
i of radioactive material or other atmospheric pollutants such as from NOx.
Policy 8.Minimize environmental,degradation in Town of Southoldfrom solid waste and hazardous
substances and wastes.See LWRP Section 111 7-Policies;Pages 34 through 38 for evaluation criteria.
Policy Standard 8.1 is not applicable to the Proposed Action; no solid waste will be generated on site as
the BESS Facility will operate unmanned. "
8.2 Manage hazardous wastes to protect public health and control pollution.
As discussed in the assessment of Policy Standard 5.2,the Proposed Action's design incorporates several
features to mitigate potential discharges of chemicals to the environment including chemicals which are in
pre-sealed in transformers/ battery units within the containers; construction of on-grade concrete pads
minimizing the potential for infiltration of chemicals into impervious surfaces or transportvia stormwater
runoff; and secondary containment for the main power transformer and medium voltage transformers.
The Proposed Action includes plans for safe waste handling and disposal and would prevent
the discharge of hazardous wastes from the BESS Facility. The facility will have an Operation and
Maintenance(O&M) Plan in place which will be compiled based on the O&M manuals from the battery and
other equipment vendors. These will be compliant with the applicable federal, state, and local laws and
manufacturers' recommendations on safe maintenance and handling of equipment. A Spill Prevention,
Control, and Countermeasure (SPCC) plan would also be developed for the Proposed Action to ensure
appropriate controls and emergency protocols. Finally, a Health,Safety, Environmental and Quality(HSEQ)
Management Plan will be in place which applies to the safety of employees of KCE,contractors and visitors

working at the Site. With the implementation of the O&M, SPCC and HSEQ policies and procedures,
pollution prevention, control and safe working practices will be in place.
KCE creates a decommissioning plan prior to project commissioning and this is updated throughout the
l Project's operational lifetime to-adhere to current standards and take advantage of new industry insights.
The decommissioning plan considers:
1. Regulatory compliance, including all end-of-life equipment handling and any battery recycling
requirements;
2. On-site equipment and plan to decommission the facility;
3. Packaging and transport of batteries, specifically to ensure compliance with hazardous
material transport laws; and
4. Record retainment for final compliance.
Both pyrometallurgic and hydrometallurgic recycling options exist within the US today and will be
considered for all end-of-life batteries to reduce environmental impact.
An example Decommissioning Plan for this project has been included as Appendix B in the Expanded
EA.
8.3 Protect the environment from degradation due to toxic pollutants and substances
hazardous to the environment and public health.
i
As discussed in the assessment of Policy Standard 5.2,the proposed facility is designed in a way to prevent
J release of toxic pollutants or substances hazardous to the environment. As discussed in the assessment
of Policy Standard 8.2, implementation of the O&M, SPCC and HSEQ policies and procedures ensures
pollution prevention/control measures and safe working practices for on-site workers will be in place.
Lithium-ion has the potential to produce gases when overheated; in response, the battery modules contain
temperature/inert gas/smoke sensors which feed into the supervisory control and data acquisition(SCADA)
system and sends data to a remote-control center. In the case an emergency is detected by the SCADA
system, the equipment resulting in the issue will be turned off before releasing gases to the surrounding
environment. As previously discussed, the battery units are self-enclosed in containers and designed to
prevent/control this issue.
Policy Standard 8.4 is not applicable to the Proposed Action as no petroleum would be present on-site.
8.5 Transport solid waste and hazardous substances and waste in a manner which
protects the safety,well-being, and general welfare of the public;the environmental
resources of the state; and the continued use of transportation facilities.
As discussed in the assessment of Policy Standard 8.2,the Decommissioning Plan includes measures to
_. ensure regulatory compliance, including equipment handling and packaging and transport of batteries,
specifically to ensure compliance with hazardous material transport laws and public safety.
Policy Standard 8.6 is not applicable to the Proposed Action as it does not involve siting of solid or
hazardous waste facilities proximate to coastal resources.

lands, and public resources of the Town of Southold. See LWRP Section III — Policies; Pages 38
through 46 for evaluation criteria.
This policy is not applicable. The Proposed Action would not impact public access to or recreational use of
public waters or open spaces within the Town.
WORKING COAST POLICIES
Policy 10. Protect Southold's water-dependent uses and promote siting of new water-dependent
uses in suitable locations. See LWRP Section III — Policies; Pages 47 through 56 for evaluation
criteria.
This policy is not applicable. The Proposed Action would not impact water dependent uses or locations.
Policy 11. Promote sustainable use of living marine resources in Long Island Sound, the Peconic
Estuary and Town waters. See LWRP Section III — Policies; Pages 57 through 62 for evaluation
criteria.
This'policy is not applicable. The Proposed Action would not impact marine resources, habitats or wetlands.
Policy 12 Protect agricultural lands in the Town of Southold. See LWRP Section III—Policies; Pages
62 through 65 for evaluation criteria.
12.1 Protect agricultural lands from conversion to other land uses.
According to the LWRP Policies document introduction to Policy 12, "the intent of this policy is to conserve
and protect agricultural land in Southold by preventing the conversion of farmland to other uses. The term
"agricultural land" is defined as: "land included in agricultural districts as created under Article 25-AA of
the New York State Agricultural and Markets Law. The term also signifies lands comprised of soils classified
in soil groups 1,2,3, or 4 according to the New York State Department of Agriculture
and Markets Land Classification System;or lands used in agricultural production, as defined in
Article 25-AA of the Agriculture and Markets Law." The Proposed Action Sites meets this definition of
agricultural land due to its location in an NYS designated agriculture district(SUFF001)and the current use
of a 15.61-acre portion of the 27.04 Site as a sod farm.
The LWRP Policies document notes that the Town has assigned priority to the preservation of
approximately 10,000 acres of land that is in active production,fallow or used for support purposes and for
the preservation of agricultural land in large contiguous blocks. The Proposed Action Site is not within
properties considered high priority as indicated on the Protected Lands within the Town of Southold Map7.
It is contiguous to farmland that appears to be active on the south however to the north, east and southeast
there is no active farmland. To the west/northwest, residential land use and agricultural use are present.
The Site is zoned LI, signaling the appropriateness of the proposed use as a public utility,which is allowed
within the LI district by Special Exception of the Board of Appeals. Additionally, the Site is surrounded on
three sides (except the western side) by LI and Light Industrial Park/Planned Office Park (LIO)zoned land.
The Proposed Action is therefore clustering this public utility use in an appropriately zoned area already
containing other active light industrial uses providing important services to the Town. Thus, while the
Proposed Action would involve conversion of farmland to a nonagricultural use, this conversion is located
on land appropriate for the proposed use that is consistent'with the surrounding land uses and zoning of
the Site.

Page 10 of 10
Policy Standard 12.2 is not applicable to the Proposed Action as the proposal does not impact the economic
parameters that make farming viable or nonviable throughout the Town.
12.3 Minimize adverse impacts on agriculture from unavoidable conversion of
agricultural land.
The Proposed Action converts only a single parcel of agricultural land to nonagricultural use in an area
zoned to allow such a use. It would not impact agricultural uses on adjacent parcels or in the vicinity of the
Site.
12.4 Preserve scenic and open space values associated with the Town's agricultural lands.
The Proposed Action is consistent with this Policy Standard as potential adverse impacts associated with
utilizing the Site for a public utility use are minimized and scenic qualities of the area are preserved with
this proposal.As described in the assessment of Policy 3.1 views of the Proposed Action will not be intrusive
to the surrounding areas.This is achieved through the BESS Facility's compact siting on south easternmost
portion of the Site closest to other industrial uses on an area of the Site set far back from public vantage
points on Oregon Road and Depot Road. A multi-acre swath of area will be preserved on the property's
Oregon Road frontage helping to maintain visual consistency with existing conditions. Further diminishing
the view of the site is the visual barrier wall installation and landscape hedgerow planting consisting of
predominantly native deciduous trees, evergreen trees, and shrubs.
The Proposed Action Site is clustered with active industrial uses in areas zoned for LI and LIO uses as
described above in assessment of Policy Standard 12.1. Additional elements to reduce potential for
adverse impacts are discussed throughout this document; protections for species are discussed in the.
assessment for Policy Standard 6.4; minimizing of potential stormwater impacts are discussed in
assessment of Policy Standard 5.2 and minimizing for cultural and historical impacts are discussed in 2.1.
Taken together, these elements minimize adverse impacts and preserve scenic character.
Policy 13. Promote appropriate use and development of energy and mineral resources. See LWRP.
Section III—Policies; Pages 65 through 68 for evaluation criteria.
Policy Standard 13.1 is not applicable to the Proposed Action as the proposals does not impact energy

Site Restoration and Decommissioning
Key Capture Energy has prepared a Decommissioning Plan that outlines the methods and
means to decommission the Project at the end of the Project's useful life.
The purpose of the Plan is to identify the methodology to be used to mitigate potential impacts resulting
from the cessation of operation of the Facility.
Utility bulk storage batteries available on the market today and like the batteries proposed for this
Project are typically designed to have a useful lifetime of approximately 20 years.Some replacement of
parts might be needed in this period, but the facility is likely to remain in operation for that duration.
The batteries will be continually,maintained throughout the life of the Project.
Performance Criteria for Site Restoration
The list below includes site restoration performance criteria proposed for Project decommissioning. .
(1) Safety and the Removal of Hazardous Conditions
Zero safety incidents is the goal.The removal of all hazardous conditions is an extension of that safety
goal. Meeting that goal includes the removal of all above ground facilities and any hazardous waste
materials upon decommissioning.
(2) Environmental Impacts
The goal of decommissioning is the safe and efficient removal of all the batteries and battery storage
energy facility components.This will include reclamation of the site to conditions as close to pre-
construction characteristics as possible. Erosion control and storm water management measures are
utilized to maintain water quality and prevent soil erosion and water runoff.All fluids and any other
hazardous materials will be removed in accordance with OSHA standards.All above ground facilities will
be removed and reseeding will take place.
(3) Aesthetics
Aesthetically, after decommissioning,the Facility Site should be in as close to pre-construction condition
as possible.That will be accomplished by removing all above ground facilities and restoring the areas
where facilities have been removed and reseeding the affected areas.
(4) Salvage and Recycling
To the extent possible,all Project materials will be salvaged and/or recycled. If possible,facilities will be
removed, relocated and reused. Metal facilities (steel, copper, aluminum) if not reused,will be salvaged
and sold for scrap metal that can be recycled for use for other manufacturing purposes.
Decommissioning & Restoration Plan
(1) Regulatory Compliance
Key Capture Energy will ensure compliance with all local,state and federal waste handling requirements. In
particular, lithium-ion batteries are considered hazardous waste and must comply with hazard waste
regulations.All necessary training and permits will be obtained prior to the commencement of
decommissioning.
(2) Plan for Decommissioning and Restoration
The Applicant has prepared the Plan to outline the methods and means to decommission the Project at
the end of the Project's useful life.The purpose of the Plan is to identify the methodology to be used to
mitigate potential impacts resulting from the cessation of operation of the Facility.
The Project will have an economical and technological lifetime of approximately 20 years.At the end
of its life the Project will be decommissioned, and batteries, containers, ancillary equipment,
buildings and infrastructure subsequently removed.
In general,facility decommissioning will occur in the general sequence outlined below:
• Disconnect battery racks within Container
• Remove Battery Racks
• Battery Disposal
• Remove Containers
• Remove Cabling
• Remove Electrical Equipment
Prior to commencing decommissioning,the Project will be shut down,de-energized and disconnected
from the Long Island Power Authority(LIPA) 69kV electric grid.The Applicant will coordinate de-
energization with LIPA and NYISO to ensure no disruption to the overall electrical system.
Additionally,the Applicant will give the Town of Southold and Cutchogue Fire Department advance
notice prior to commencing decommissioning activity.
All aboveground components including buildings,structures and equipment will be removed during
decommissioning. In addition, all foundations will be removed to a certain depth below ground surface,
backfilled and then covered with topsoil.
The goal of decommissioning is the safe and efficient removal of all facility components and reclamation
of the site to conditions as close to pre-construction characteristics as practicable.The same safety
protocols that are used during construction will be used during decommissioning.
The decommissioning process is expected to take approximately.three months.This time includes
one-week site mobilization and preparation;six-week period to dissemble the facility; an additional
five-weeks to remove and reclaim foundations and reclamation work including grading, backfilling,
erosion control activity, reseeding will take place.
(3) Packaging and Transportation
The batteries must be packaged by trained contractors with all necessary hazardous materials training.
While the United States does not currently allow for the transport of full containers with all batteries
installed, it is anticipated that this will be allowed in the near-term.The batteries will be transported by a
Class 9 Hazmat qualified contractor.
(4) Recycling
There are three potential methods for battery recycling,two of which are currently commercially viable in
the United States.At the end of the project lifetime, KCE will review all available recycling methods and
industry standards to select the optimal recycling program.The available recycling methods are:
1. Pyrometallurgic:This process uses high temperatures to separate the components of a battery.
Metal alloys are retrieves from the process that can be used in industrial uses.Slag is also retrieved
I j and can be used in road construction.
2. Hydrometallurgic:This process uses,chemicals and mechanical separation to dissolve and extract
specific metals from the batteries.The raw metals can then be used in new batteries or in another
industrial use.
3. Direct:While direct recycling is not commercially available in the United States today, it is the most
sustainable recycling option. Electrolytes are removed and purified,which allows re-use in new
.batteries.
(5) Record Retention
KCE will ensure that all bill-of-lading and evidence of proper waste handling are retained for a minimum of
two years or to the duration that the current law requires.

Last Revised 4/26/2022 by Land Use Ecological Services,Inc.
Expanded Task 2: Critical Issues Analvsis for H2M-Key Capture Energy, Cutchogue
As requested,Land Use Ecological Services,Inc.has reviewed a number of online resources in order to complete a desktop
analysis of natural resources at the KCE NY 26 Battery Energy Storage Facility site at 10750 Oregon Road in Cutchogue,
NY. Databases and resources reviewed for this analysis include the NYS Environmental Resource Mapper, NYS Tidal
Wetlands Inventory Maps,NYS EAF Mapper,NYS Nature Explorer,USFWS NWI Mapper, and USFWS iPAC database.
A detailed analysis of wetlands and water resources, threatened and endangered species, critical environmental areas, and
sensitive habitats for the KCE NY 26 Battery Energy Storage Facility site is provided below.
1. Wetlands and Water Resources:
The NYS Environmental Resource Mapper,NYS Tidal Wetlands Inventory Maps (#708-544), and USFWS NWI Mapper
were reviewed for site proximity to tidal and freshwater wetlands (Appendix A). Assessment of these resources indicated
that there are no regulated wetlands on, or adjacent to,the project site. According to these map resources,the nearest tidal
and/or freshwater wetlands are located approximately 0.5 miles north of the project site. A field inspection of the property
on June 1, 2021 by William P. Bowman, PhD of Land Use Ecological Services confirmed that there are no freshwater or
tidal wetlands or surface water resources on the subject property. No communities of wetland or hydrophytic vegetation or
indicators of wetland hydrology were observed.
2. Threatened and Endangered Species:
Correspondence from the New York Natural Heritage Program(dated October 27,2021)indicated that the subject property
occurs within 1.25 miles of known, non-winter locations for Northern long-eared bat (Myotis septentrionalis) (Appendix
B). In addition, review of the NYS Environmental Resource Mapper (Appendix C),NY Nature Explorer(Appendix D),
and USFWS iPAC database(Appendix E)indicates that several threatened or endangered species have potential to occur at
the project site. According to the NYS Environmental Resource Mapper, Northern long-eared bat (Threatened) may be
present in the vicinity of the project site. Per NY Nature Explorer, listed or protected species include Bushy Rockrose
(Crocanthemum dumosum, NYS- Threatened), Velvety Bush Clover (Lespedeza stuevei, NYS-Threatened), Woodland
Agrimony (Agrimonia rostellata, NYS Threatened). Both Lespedeza stuevei and Agromonia rostellata are known from .
historical records in 1919 and 1932, respectively.
According to the USFWS iPAC database, Endangered Species Act-listed mammal, bird, and plant species for Suffolk
County include the Northern long-eared bat(Threatened),Piping plover(Threatened),Red knot(Threatened),Roseate tern
(Endangered), Sandplain gerardia (Endangered), and Seabeach amaranth (Threatened). It should be noted that the iPAC
database is not site specific,but rather county specific.Piping plover,red knot,roseate tern,sandplain gerardia,and seabeach
amaranth inhabit beach and shoreline/wetland habitats that are not found on the project site.Northern long-eared bat is
found in many forested sites on eastern Long Island with mature hardwood trees and could be found on the project site.
Additionally,the USFWS iPAC report indicates a total of 12 bird species that are protected under the Migratory Bird Treaty
Act that may inhabit or utilize the site for breeding. The potential presence of bird species protected under the Migratory
Bird Treaty does not impose any regulatory constraints on the development of the subject property. Furthermore, none of
the migratory bird species listed on the iPAC report are expected to utilize the subject property during breeding or
migratory seasons based on field conditions observed during June 1,2021 field investigation.
Although the resources consulted indicate potential presence of the above threatened and endangered species, it should be
noted that actual site conditions may, or may not, provide suitable habitat for many of these species. In order to confirm
actual or probable occurrence of these species,a field investigation was conducted on June 1,2021 and in-depth endangered
species analysis was completed.
Regulatory Implications
The Northern long-eared bat is listed as threatened federally and by New York State and is known to occur within 1.25
miles of the property (Appendix B). NYNHP correspondence does not indicate that the project site is within '/4 mile of a
hibernation site or 150 feet of a known roost tree.
Expanded Task 2-Critical Issues Analysis
H2M-Key Capture Energy,NY 26 Battery Energy Storage Facility,Cutchogue,NY
Last Revised 4/26/2022 by Land Use Ecological Services,Inc.
The small forested areas on the subject property,including the 2.0 acre forest patch on the northeast portion of the property,
provide suitable daytime roosting sites from northern long-eared bat due to the presence of mature hardwood trees,such as
oaks and hickories,with potential cavities and exfoliating bark.
In order to comply with NYSDEC guidance intended to minimize potential impacts to Northern long-eared bat, all tree
clearing on the property must be completed between December 1 — February 28. No Article 11 (Incidental Take of
Threatened/Endangered Species) permit from the NYSDEC is required for the project if all tree clearing can be
accomplished between December 1 —February 28.
Due to the property's location within 1.25 miles of known,non-winter bat locations,consultation with the Town of Southold
is recommended during Board or site plan review phases to determine if bat-specific requirements or conditions will be
included in Town-issued authorizations for the project. Conditions or requirements could include recommendations to
preserve trees capable of providing bat roots to the maximum extent practical.
Per NY Nature Explorer,listed or protected species include Bushy Rockrose(Crocanthemum dumosum,NYS-Threatened),
Velvety Bush Clover(Lespedeza stuevei,NYS-Threatened),Woodland Agrimony(Agrimonia rostellata,NYS Threatened)
may be present on the subject property. Field investigations conducted on June 1, 2021 indicate that these species are not
present on the subject property and that suitable habitat for these species is not present on the property. Accordingly, no
impacts to these species are expected to result from the proposed project.
Bushy rock rose (Crocanthemum dumosum) is a New York State-threatened species that occurs in various open habitats
with dry,sandy soils including coastal oak-hickory forests,maritime grasslands,maritime shrublands,mowed habitats with
trees, pitch pine-oak forests, and pitch pine-oak-heath woodlands (NYNHP, 2021a). A field investigation was conducted
on June 1, 2021 to determine if this species is present on the 10750 Oregon Road property. Bushy rock rose was not
observed on the subject property,nor were typical dry,sandy habitats for this species observed. The site consists largely of
current and former agricultural fields dominated by successional weeds and grasses including orchard grass (Dactylis
glomerata), wild radish (Raphanus raphanistrum), and mugwort (Artemesia vulgaris). The site's limited forest habitats,
including the—2.0 acre forest stand located on the northeast side of the property, is dominated by American beech(Fagus
grandifolia),pignut hickory(Carya ovata),and various oaks,typically white oak and black oak(Quercus alba and Quercus
velutina). The ground-layer vegetation in the forest patches on and adjacent fo the subject property is sparse and dominated
by Virginia creeper(Parthenocissus quinquefolia), prickly dewberry (Rubus flagellaris), Japanese honeysuckle (Lonicera
japonica),white snakeroot(Ageratina altissima),cleavers(Galium aperine), garlic mustard(Alliaria petiolata),and Asiatic
bittersweet (Celastrus orbiculatus). The understory of the forest patches has been historically disturbed with abandoned,
dilapidated farm equipment present. The ground-layer and shrub-layer vegetation in these forest patches does not feature
plant species that bushy rock-rose is typically associated with including bearberry(Arctostaphylos uva-ursi),Pennsylvania
sedge(Carex pensylvanica),poverty grass(Danthonia spicata),pinweed(Lechea maritima), eastern prickly-pear(Opuntia
humifusa),staggerbush(Lyonia mariana)and bayberry(Morella pensylvanica). The mowed margins of the site's road and
trails and hedgerows were also surveyed for bushy rock rose. These portions of the site were dominated by mugwort
(Artemusia vulgaris), orchard grass (Dactylis glomerata), poison ivy (Toxicodendron radicans), Virginia creeper
(Parthenocissus quinquefolia),prickly dewberry(Rubus flagellaris),Indian strawberry(Duchesnea indica),multiflora rose
(Multiflora rose), Asiatic bittersweet (Celastrus orbiculatus), Alleghany blackberry (Rubus alleghaniensis), ground ivy
(Glechoma hederacea), bitter dock (Rumex obtusifolius), hawkweed (Hieracium sp.), winged sumac (Rhus copallinum),
autumn olive (Elaeagnus umbellata), shrub honeysuckle (Lonicera sp.),bayberry (Morella pensylvanica), sassafras
(Sassafras albidum), black cherry (Prunus serotina) Bush rock rose was not observed in these mowed road margin or
hedgerow habitats either.
Velvety Bush Clover (Lespedeza stuevei) is a New York State-Threatened species typically found in disturbed grassy
openings within pitch pine scrub oak barrens,pitch pine oak woods and coastal oak hickory woods(NYNHP,2021b). This
species is best identified between August and October. However,this species is not expected to be present on the site as 1)
typical habitat for this species is not present on the subject property,2)no Lespedezas or common associates were observed,
and 3)the existing record for this species in Appendix C is from 1919.
Woodland agrimony (Agrimonia rostellata) is a New York State-Threatened) species found in moist rich woods, oak-
hickory woods, sandy clearings, and thickets(NYNHP, 2021c). Voss 1985)..This species is best identified between early

July and mid-September. However, this species is not expected to be present on the site as 1) no 4gromonia sp. were
observed on the subject property and 2)the existing record for this species in Appendix D is from 1932.
3. Critical Environmental Areas:
According to the NYSDEC EAF Mapper(Appendix F),this site is not located on or adjacent to any Critical Environmental
Areas(CEA's).
4. Sensitive Habitats:
There are no sensitive habitats present on, or within close proximity to, the project site as per review of the NYS Nature
Explorer(Appendix D)and USFWS iPAC database(Appendix E).

Re: Proposed 60 MW.Battery Energy Storage Facility at 10750 Oregon Road, Cutchogue
County: Suffolk Town/City: Southold
Dear William Bowman:
In response to your recent request, we have reviewed the New York Natural Heritage
Program database with respect to the above project.
We have no records of rare or state-listed animals or plants, or significant natural
communities at the project site.
Within 1.25 miles of the project site are two documented non-winter locations of
Northern long-eared bat (Myotis septentrionalis, state-and federally listed as Threatened).
The bats may travel 1.5 miles or more from documented locations. The main impact of
concern for bats is the removal of potential roost trees. For information about any permit
considerations for your project, please contact the Permits staff at the NYSDEC Region 1
Office, Division of Environmental Permits, at dep.rl@dec.ny.gov.
For most sites, comprehensive field surveys have not been conducted. We cannot
provide a 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 resources may be required
to fully assess impacts on biological resources.
For information regarding other permits that may be required under state law for
regulated areas or activities (e.g., regulated wetlands), please contact the Permits staff at the
NYSDEC Region 1 Office as described above.

T Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely to be
present in your project area. This information can be used to tailor and schedule your project
activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ
"Proper Interpretation and Use of Your Migratory Bird Report" before using or attemptingto �-;
interpret this report. �
Probability of Presence (o) ;. ' r
� ;
g
Each green bar represents the bird's relative probability of presence in the 1Okm grid cell(s)your
project overlaps during a particular week of the year. (A year is repretsented'�as 12 4-week months.)
Vi
' A taller bar indicates a higher probability of species presence:The survey effort(see below) can be
used to establish a level of confidence in the presence sc& ne can have higher confidence in the
presence score if the corresponding survey effort.jsalsohlgh:
How is the probability of presence scoregcdlculated?The calculation is done in three steps:
ij .,
1. The probability of presence�fat each wg k"is calculated as the number of survey events in the
week where the species wOdetectted divided by the total number of survey events for that
week. For example, If in wei&'1a2 there were 20 survey events and the Spotted Towhee was
found in 5 of thek::the probability of presence of the Spotted Towhee in week 12 is 0.25.
2. To properly$presentthe pattern of presence across the year,the relative probability of presence
is calculated`this is the probability of presence divided by the maximum probability of presence
across allweeks. For example, imagine the probability of presence in week 20 for the Spotted
' _Tovuhee Is 0.05, and that the probability of presence-at week 12 (0.25) is the maximum of any
week of the year.The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is
0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive.This is the probability of
presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
- Breeding Season (o)
Yellow bars denote a very liberal estimate of the-time-frame inside which the bird breeds across its
entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.
Survey Effort(1)
https://ecos.fws.gov/ipac/location/ZIDS7G7L5RCBLJZMJGYVE3D6BI/resources 6/12
6/2/2021 IPaC:Explore Location resources
Vertical black lines superimposed on probability of presence bars indicate the number of surveys
performed for that species in the 1 Urn grid cell(s)your project area overlaps. The number of
surveys is expressed as a range,for example, 33 to 64 surveys.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data (—)
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast,where bird returns are based on all
years of available data, since data in these areas is currently much more sparse.

The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network
(AKN).The AKN data is based on a growing collection of survey, banding,and citizen science datasets and is
queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s)which your project
intersects,and that have been identified as warranting special attention because they are a BCC species in that
area, an eagle Eagle Act requirements may apply),or a species that has a particular vulnerability to offshore
activities or development.
Again,the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not
representative of all birds that may occur.in your project area.To get a list of all birds potentially present in your
project area, please visit the AKN Phenology Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially

How do I know if a bird is breeding,wintering, migrating or present year-round In myproject area?,
To see what part of a particular bird's range your project area falls,withiri.(i e breeding,wintering, migrating or
year-round),you may refer to the following resources:The CornelhLab of'Orn`ithology All About Birds Bird Guide, or
(if you are unsuccessful in locating the bird of interest there),the'CorneIJ'Lab of Ornithology Neotropical Birds
guide. If a bird on our migratory birds species list has a breedln season associated with it, if that bird does occur

in your project area,there may be nests presenvat some p,6A within the timeframe specified. If"Breeds
elsewhere" is indicated,then the bird likely does not breed in your project area.
What are the levels of concern for migratory birds?
Migratory birds delivered thr6b h IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds:are Birds of Conservation Concern (BCC)that are of concern throughout their range
anywhere Within the USA(including Hawaii,the Pacific Islands, Puerto Rico, and the Virgin Islands);
2. "BCCA'-BCR birds are BCCs that are of concern only in particular Bird Conservation Regions(BCRs)in the
:, continental USA; and
3.'-'Non`BCC-Vulnerable" birds are not BCC species in your project area, but appear on your list either because
of the Eagle Act requirements(for eagles)or(for non-eagles) potential susceptibilities in offshore areas from
certain types of development or activities(e.g. offshore energy development or longline fishing).
Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular,to
avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For
more information on conservation measures you can implement to help avoid and minimize migratory bird
impacts and requirements for eagles, please see the FAQs for these topics.
Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species and groups of
bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal.The Portal
also offers data and information about other taxa besides birds that may be helpful to you in your project review.
Alternately,you may download the bird model results files underlying the portal maps through the NOAA NCCOS
Integrative Statistical Modeling and PredictiveMapping of Marine Bird Distributions and Abundance on the Atlantic
Outer Continental Shelf project webpage.

Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level
information on the location,type and size of these resources.The maps are prepared from the analysis of high
altitude imagery.Wetlands are identified based on vegetation,visible hydrology and geography.A margin of error
is inherent in the use of imagery;thus,detailed on-the-ground inspection of any particular site may result in
revision of the wetland boundaries or classification established through image analysis.
The accuracy of image interpretation depends on the quality of the imagery,the experience of the image_analysts`,�'
the amount and quality of the collateral data and the amount of ground truth verification work conducted.'
Metadata should be consulted to determine the date of the source imagery used and any mapping,prozblems. }
Wetlands or other mapped features may have changed since the date of the ima e o.r field work.There ma be
PP Y g g ry--,- h.. y
occasional differences in polygon boundaries or classifications between the information depicted on the map and
the actual conditions on site. i.. ,
Data exclusions
Certain wetland habitats are excluded from the National.'a-pping program because of the limitations of aerial
imagery as the.primary data source used to detect Wetlands:These habitats include seagrasses or submerged
aquatic vegetation that are found in the intert&d:and subtidal zones of estuaries and nearshore coastal waters.
Some deepwater reef communities(coral or t0berficid Worm reefs) have also been excluded from the inventory.
These habitats, because of their depth,go undetected by aerial imagery.
Data precautions
Federal,state,and,local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a
different,Ima`nner than that used in this inventory.There is no attempt,in either the design or products of this
inventory.,to define the limits of proprietary jurisdiction of any Federal, state,or local government or to establish
the=geographical scope of the regulatory programs of government agencies. Persons intending to engage in
activities-involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal,
state,or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may
affect such activities.

Subject: KCE NY 26 Battery Energy Storage System Noise Evaluation
Cutchogue/Southold, NY
Acentech Project No.: P635300, Revision 3
Dear Joel:
We have conducted a noise evaluation for a battery energy storage system (BESS) for Key Capture Energy
(KCE). The project is to be located on a 27-acre site located at 10750 Oregon Road, in the Hamlet of .
Cutchogue, Town of Southold, Suffolk County, New York ("KCE NY 26"). To determine the impact of the
BESS, we developed an acoustic model to calculate the expected sound levels of each of the noise
producing equipment at nearby community receivers. The equipment includes battery storage containers,
inverters, substation transformers, and air conditioning for control houses.
PROJECT NOISE REQUIREMENTS
TOWN OF SOUTHOLD
The Town of Southold noise ordinance (Section 180-6 Standards) limits sound levels at the property line of
the receiving property based on the time of day, the sound source category, and the receiving property
category. The relevant project limits are provided in Table 1. The controlling noise limit will be the residential

STATE OF NEW YORK
The New York State Department of Environmental Conservation (NYSDEC) has published a Program Policy
Memorandum entitled "Assessing and Mitigating Noise Impacts"dated 10/6/2000 and revised 2/2/2001. This
document does not provide a fixed numerical sound limit, but provides general guidance on increases in
noise levels due to stationary sources of sound:
Increase in ambient of 0-3 dB: "No appreciable effects on receptors"
Increase of 3-6 dB: "may have potential for adverse noise impact only in cases where the most

sensitive of receptors are present"
Increases of more than 6 dB: "may require a closer of analysis of impact potential depending on
existing sound pressure levels and the character of surrounding land use and receptors"
The guidance document suggests that one can assume a background sound level of 45 dBA for a"quiet,
seemingly serene setting"which would describe this project area. Based on this assumed ambient, we can
provide some qualitative estimates of the impact of the project given the NYSDEC guidance. For this
requirement,we will evaluate the sound levels at the nearest residential abutters to KCE NY 26.
PURE TONE REQUIREMENTS
The NYSDEC guide' has a qualitative guidance regarding sounds that produce a"pure tone"or a"discrete
.tone"(See section V.13.5 for definition). Section V.4 states that, "Pure tones are relatively rare in nature but, if
they do occur,they can be extremely annoying". This type of sound is of concern here because the project
equipment, in particular the inverters and transformers can produce pure tones as part of the process of
converting and transforming direct current(DC) power into 60 Hz alternating current(AC). The pure tones
are produced at twice the line frequency and harmonics (120, 240 and 480 Hz). The NYSDEC policy noted
above also comments on the existence of pure tones, but does not have specific qualitative or quantitative
limitations.
NOISE COMPUTATIONS
Acentech developed an acoustic model of the proposed BESS and surrounding neighborhood.The acoustic
model was developed using Cadna/A software to estimate the contributions of various noise sources to the
community sound levels. Cadna/A complies with international standard ISO 9613-2"Attenuation of sound
during propagation outdoors-- Part 2: General method of calculation." The sources of noise included any
sound producing equipment as described below.
PROJECT SITE DESCRIPTION
Figure 1, attached, shows the proposed site plan.We have identified six residences in the surrounding
neighborhood as shown in Figure 2. These residences are representative of the closest proximity residences
to the project site, which would represent homes with the loudest project sound levels. There are other
residences nearby each receiver,which we expect to have similar sound levels. Figure 2 also shows the
project property line at which points we will evaluate the Town of Southold noise limits given in Table 1.
EQUIPMENT SOUND LEVELS
Table 2 provides the input sound power level (Lw)for the BESS sound producing equipment. Spectral data
for some equipment was based on previous project experience, and we expect similarly selected equipment
to produce similar overall sound levels for this project. The tonal character of the actual equipment used in
this project will depend on the specific equipment selections. Project sound sources are identified with red
crosses on Figure 2. The noise producing equipment at BESS includes:
Sixty-eight(68) battery storage groupings with four Sungrow model ST2752UX containers each (for
a total of 272 units).The octave band sound data provided for the battery storage containers were
provided by the manufacturer and measured under extreme temperature and load conditions.The
battery storage container model is designed for a maximum power of—1376 kW when installed at its
peak power rating for a 2-hour system. KCE NY 26 is an 8-hour system, and will therefore run at
25%of the full electrical current(i.e. load) per BESS enclosure.With conservative assumptions
regarding battery operation,the project engineers have determined that a halving of current leads to
a 53% reduction in fan speed.We have estimated that this could result in a 6 dB reduction in overall
sound levels per battery storage container, which is appropriate operating scenario given the details
outlined above.

Seventeen (17) inverters (5000 kW), by Sungrow, model SC5000UD. The manufacturer provided
1/3-octave band sound power levels and overall sound pressure levels at 1 meter,from which we
calculated octave band sound power levels to use in our acoustic model.
One (1) main power transformer(MPT).We have assumed a transformer with a NEMA TR-1
guaranteed maximum noise level of 85 dB at 100%.load, an average sound pressure level rating at 2.
meters. We estimated octave band sound power levels based on our prior project experience and
engineering knowledge.
Two (2) HVAC units: Marvair ComPac I and 11. The HVAC units located on the substation control
house are equipped with a silencer to reduce sound levels. Manufacturer provided overall sound
pressure level at various distances.We calculated an overall sound power level for this device based
on that data and estimated octave band levels.

SOUND BARRIER WALLS
The baseline design of the BESS is surrounded fully to the West and partially to the North and South by
sound barrier walls that are 12 feet high above the ground. The selected noise barrier must be continuous,
avoiding gaps between the modular pieces. The noise barrier should be rated at STC 25 or higher to provide
adequate performance. The barrier wall construction should have an absorptive finish on the side facing the
equipment;to achieve this you must have a perforated finish exposing the sound-absorptive material.Where
sound absorption is needed,the sound absorptive surface should achieve a minimum NRC rating of 0.70.
The sound barrier is shown in Figure 3.
There is an opening for emergency egress and site access (-20 ft)for access roads to the west.We are
assuming these openings will be provided with a chain-link gate, so we have modeled them as an opening
between the two sides of the wall seen in Figure 3.
Residential Receptors
As noted above, we have identified six residences in the surrounding neighborhood at which to evaluate
noise. Figure 2 shows the receptor locations, identified as black and white circles, denoted R-1 through R-6
near the BESS.We calculated the nighttime sound level at these locations with receptor heights of 5 feet(1.5
meters) representing ground level receptors at the adjacent properties.
RESULTS
We calculated project only sound levels at each receptor using the Cadna/A noise model and combined it
with the assumed ambient sound level of 45 dBA to determine the future sound levels. We have then also
determined the increase over ambient at the six residential receptors locations.The project and ambient
sound pressure levels noted above add logarithmically.The combined future sound levels can be compared
to the Town of Southold's 50 dBA nighttime residential limit. The increase over ambient can be compared to
the guidance provided by NYSDEC. Table 3, presents the predicted sound levels for each receiver.
Figure 4 shows the 50 to 85 dBA sound contours for night operation at a height of 5 feet(1.5 m) above the
ground. The purple line shows the project property line.. The Town of Southold nighttime sound limit is 50 .
dBA as given in Table 1. Anywhere the 50 dBA contour(outer grey contour in Figure 4) passes the property
line in purple are points at which the 50 dBA sound limit is exceeded at the property line. We have calculated
ONO- ACENTECH

Page 4 of 8
that this excess is no more than 5 dB at the property line. Put another way, we estimate that the 50 dBA
contour goes no more than 250 feet past the property line.

CONCLUSIONS
Project noise levels will not exceed the Town of Southold's nighttime residential noise limit of 50 dBA at
neighboring residences. Further, based on the assumed background sound level of 45 dBA,we estimate that
the project noise levels at residential receivers will only increase the background sound levels at a single
nearby residential receivers by no more than 1 dBA. This falls into the NYSDEC category wherein"No
appreciable effects on receptors" is expected.
At the property line,we expect background noise levels to increase by 5 dBA, which falls into the NYSDEC
category of"may have potential for adverse noise impact only in.cases where the most sensitive of receptors
are present."Given the agricultural use of land at this property line, we expect the receptor is not in the"most
sensitive"category, and therefore do not expect adverse noise impacts. We recognize that on some of these
properties sit residential homes, but we are not predicting excesses at the residence.
We have examined the calculated octave band sound pressure level data for the existence of Pure Tones.
The project octave band sound data has potential for pure tone conditions; however, the potential for a pure
tone is at a low sound pressure level. When this sound pressure level is combined with an existing ambient
sound level of 45 dBA the ambient sound will mask the pure tone condition.
