Mattituck Harbor has two jetties, the east which was constructed in 1906 and the west jetty was constructed in 1938. USACOE has deemed Mattituck Harbor a navigational asset to the United States with regards to commerce as it supports recreational boating and several marinas,including Strong's Yacht Center(SYC),and serves as a "Harbor of Refuge" during severe storms. Mattituck Harbor is a designated Federal Navigation Channel under the Rivers and Harbors Act of 1896 (29 Stat. 202), modified in 1935 (P.L. 74-409) and 1964. This designation gives authority to the USACOE to maintain the navigability of the channel. Due to the filling of Mattituck Inlet and Creek through natural processes, USACOE routinely dredges Mattituck Inlet and Mattituck Creek to ensure the water body remains safe for navigation.The USACOE, in coordination with NYSDEC and the Town of Southold, developed a routine dredging program for Mattituck Inlet in the early 2000's that came to fruition in 2014. USACOE recognized Mattituck Inlet as, "a vibrant fishing, boating and recreation site along the Long Island Sound and provides safe navigation from the Long Island Sound through Mattituck Inlet. It is also a Critical Harbor of Refuge. Two jetties are the aids to navigation currently in operation. As a result of past jetty construction, the west jetty fillet fills in rapidly while the down-drift beach is sand-deprived. Monitoring the conditions periodically is the minimal reasonable stewardship."' The existing program provides for a minimum channel depth of 7-feet from Long Island Sound to the Village of Mattituck. In 2014, Mattituck Inlet was dredged to a depth of 13 feet. Dredging programs ensure higher water quality as natural ecosystems can function as intended. The most recent dredging of Mattituck Harbor was completed in 2014, under Section 111 of the Continuing Authorities Program (CAP), during which 100,000 cubic yards (CY) of material was dredged and placed along the shoreline of Baillie Beach in Mattituck.

PWGROSSER.COM PAG CLIENT DRIVEN SOLUTIONS 1.1.2 Local Maritime Asset The importance of Mattituck Creek is further recognized by the Town of Southold in its Local Waterfront Revitalization Program (LWRP)4, as well as the recent Southold Town Comprehensive Plan,dated February 2020 and Adopted September 2020(hereinafter the "2020 Comprehensive Plan")5. LWRP The LWRP is a New York State-approved comprehensive management plan that is aimed at balancing the preservation, enhancement, and utilization of the valuable local waterfront resources in the Town of Southold. Mattituck Inlet and Mattituck Creek are identified as marine assets to the Town.The LWRP identifies SYC as being within Reach 1 which "...stretches east along the Long Island Sound shoreline from the boundary between the Town of Riverhead and Southold to Duck Pond Point, Cutchogue. Its inland boundary is Old Sound Avenue and County Route 48. The Reach includes the communities of Mattituck Hills and Oregon Hills, a well as the northern reaches of Mattituck hamlet." (Section 1-4) As noted in the LWRP, "[t]here are not many development constraints within Reach 1, a situation that makes this Reach highly vulnerable to residential development pressures." (Section II-J Reach 1-26). This is particularly pertinent to SYC as portions are zoned within the Marine II (M-11) District and Low-Density Residential District (R-80). Within the M-II District, one-family detached dwellings are permitted. SYC's function as a boat repair, maintenance, storage, sales and marina is therefore important to sustaining maritime uses within Reach 1. Furthermore, the LWRP notes that the M-11 District "...allow[s] the potential for non- water-dependent uses. These uses are considered 'water-enhanced'in that they provide different forms of public access to the waterfront (e.g., restaurants, hotels). However, here, the loss of commercial docking and support facilities would be devastating to commercial fishing operations,since the facilities in Mattituck are the only ones available along this stretch of the Long island Sound."(Section 11-J Reach 1-14).SYC operates within this capacity as it provides water-enhanced uses like storage, maintenance, and docking for commercial fishing boats to support the commercial fishing industry. 4 https://docs.dos.ny.gov/opd-lwrp/LWRP/Southold T/Amendmentl/Final/SoutholdAmend.pdf 5 http://www.southoldtownny.gov/DocumentCenter/View/7855/Southold-Town-Comprehensive-Plan-Vol-1 GROSSERZEN l PHONE: 631.589,6353 630 IOHi'TTaTa"` .AVlwNU ,STT 7' P.W.

As excerpted, Mattituck Harbor is ".. the only harbor fronting on Long Island Sound. It is both a recreational and commercial port and is the site of one of the Town's largest concentrations of marine facilities, second only to Greenport Village." (Section II — J Reach 1-3). Furthermore, "Mattituck Inlet provide[s] the most suitable and appropriate location[s]for new or expansion of existing water-dependent commercial and industrial uses." (Section II —J Reach 1-4). Additionally, the Long Island Sound Comprehensive Management Program (NYSDOS, 1999) identifies Mattituck Inlet as one of ten maritime centers on Long Island. Regarding shellfishing, the LWRP notes that Mattituck Inlet "... contains extremely productive shellfish beds producing hard and soft clams and oysters that are harvested both commercially and recreationally. It is considered by the local baymen to be one of the most productive creeks in the Town."(Section II-J Reach 1-11). As discussed in Section 3.2 of this report, existing water quality issues related to toxic algal blooms within Mattituck Harbor have led to seasonal shellfish closures with ongoing and active measures being undertaken to improve water quality. One such measure is the Cornell Cooperative Extension (CCE) Marine Program's FLUPSY program, which provides protected nurseries for hard clam seed to assist with the New York State (NYS) Shellfish Restoration Initiative. SYC is the current host of such program in Mattituck Harbor. Additional details related to the program are discussed in Section 3.1.4 of this report. 2020 Comprehensive Plan The 2020 Comprehensive Plan recognizes the important role Mattituck Creek in relation to the overall character of the Town in several of the Plan's chapters. Specifically, the Community Character and Economic Development chapters have goals and objectives related to the maritime importance of Mattituck Inlet and Creek to the Town. Regarding community character, the 2020 Comprehensive Plan focuses on the Town's future development strategy to retain the overall uniqueness of the Town with regards to scenic resources, cultural resources, and natural heritage (page iii).6 Within the Community Character chapter, Goal S is related to the importance of Mattituck Inlet to the Town,to wit: "Protect the unique character of individual hamlets. For Mattituck:(A)revitalize Mattituck inlet into recreational and maritime hub by 1. reconnect the waterfront 'Ibid. IN P.W. GROSSER CONSULTING, INC.

Regarding economic development,the 2020 Comprehensive Plan addresses economically appropriate development initiatives (page 1). The economic development chapter specifically identifies maritime uses are an important component of the Town's economy and how to encourage their appropriate growth in Goal 5, Objectives 5.1, 5.4, and 5.7. The goal and objectives are included below. ➢ Goal 5 — Preserve, encourage, and continue to support existing and future maritime uses as an important business sector within the Town's economy. (page 20) In 2020, Strong's Marine paid approximately $2.7 million in sales and property taxes. Upon implementation of the proposed action, an additional 11 full-time positions are expected to be created; many of which would be specialty trades in the maritime industry. The salary ranges for the new full-time positions could be expected from approximately$50,000 to$125,000. In addition to the creation of jobs,the proposed action is also expected to increase tax revenue to the Town of Southold, Suffolk County, and the State of New York. It is expected that the proposed action could generate an additional $474,375 a year in sales tax revenue from the storage of yachts and additional yacht sales. Within the Town of Southold,the proposed development is expected to increase property taxes by $59,450 per year based upon the Southold Assessor (see correspondence dated June 25, 2021 in Appendix E of the Draft Environmental Impact Statement [DEIS]); however,the property would be eligible for the 485-b Business Investment Exemption, which is a tax reduction on a sliding scale over 10 years. For the first 3 years, there would be a 50 percent reduction for the increased assessment attributable to the two new buildings. For each year after, the reduction would decrease as follows:Year 4:40 percent, Year 5: 30 percent, Year 6: 20 percent, Years 7 thru 9: 10 percent, and Year 10: 5 percent. The proposed action represents a continued investment of the Applicant into the Town of Southold, which over the last eight years, has included property investments that have contributed nearly $300,000 into the Town's land P.W.

Community Preservation Fund). Overall,based on the above,the proposed action responds to the market demand for indoor yacht storage, creates new employment opportunities for maritime trades, and would increase direct tax revenues from income, sales and property taxes. As evaluated in the DEIS (Section 3.9), the proposed action also results in indirect economic benefits. ➢ Objective 5.1 — Maintain consistency with the policies adopted under the Local Waterfront Revitalization Program. (page 20) As excerpted from the 2020 Comprehensive Plan, the LWRP "...emphasizes the importance of coastal zone and traditional maritime uses in terms of the commercial and recreational qualities of the Town. The LWRP also recommends waterfront access and water-dependent/water-enhanced uses, and provides an array of information relating to coastal and Townwide resources. The Town should be consistent with all policies adopted under this program, as it pertains to all future development and maritime uses." SYC's operations support the Town's ability to successfully implement the LWRP as they continue to expand the marina services offered while making efforts to enhance the surrounding marine environment through the operation of the CCE FLUPSY units at the site and the provision of pump out services to boats at the marina and on Mattituck Creek and Inlet. A consistency analysis with the LWRP policies is included in the DEIS in Section 3.1.2, which demonstrates consistency with the goals and recommendations for the Reach. Accordingly,SYC's operations,both current and proposed, are consistent with Objective 5.1. ➢ Objective 5.4 — Consider amendments to the zoning of larger marinas to better accommodate and position them as a viable use in the Town's economy.". (page 21) As excerpted from the 2020 Comprehensive Plan, "Large marinas are facing pressures to expand their services to include swimming pools, restaurants, boat rentals, storage space, and other services that cater to their customer's needs. In order to accommodate this demand and continue to promote Southold's traditional maritime heritage, the Town should consider zoning amendments for marinas of appropriate size and location to better match the needs of their clients. The subject property is appropriately zoned to support the services SYC offers. IN I P.W. GROSSER CONSULTING, C. PHONE: 631.589,6353 630JOHNSON AVENUE,STE 7 P.W.

Additionally,the provision of additional storage space at SYC directly caters to the needs of the customers and demand within the market. ➢ Objective 5.7—Enhance the connection between Mattituck Inlet and the hamlet center...Mattituck Inlet is an important economic, environmental, and recreational resource in the hamlet of Mattituck. Located just north of the hamlet center, Mattituck Inlet runs two miles into the North Fork from Long Island Sound, and is the only harbor on the±50 mile stretch between Port Jefferson and Orient Point. As such, Mattituck serves as an important maritime location with the Inlet being a popular destination for boaters. The hamlet's accessibility to water, in addition to a designated anchorage, a Town park and boat ramp, marinas, and maritime uses located close to the hamlet center make it a key economic driver...B. Increase access through regular dredging of Mattituck Inlet."(page 23) The current operation of SYC supports this objective as it provides services to both private yacht owners as well as the commercial fishing industry.As discussed in Section 1.1.1 below, routine dredging is completed within Mattituck Inlet to ensure navigation is maintained. It is noted that there is no dredging required for the proposed SYC project. SYC's operations help aid the Town of Southold in achieving this goal. .2 Navigation and User Groups 1.2.1 Depths of Mattituck Inlet and Mattituck Creek Inlet soundings at low tide were performed by H&L Contracting LLC for Mattituck Creek from the inlet at Long Island Sound to SYC on April 8,2020 to document the various depths of the inlet and creek (see Figure 2). It is noted that the soundings were performed to determine whether suitable depths existed for barging of cut materials from the project site. P.W. GROSSER CONSULTING, INC.

In some instances, approximately 0.40 mile into Mattituck Creek, the channel becomes narrow for approximately 0.25 mile and the depths are seven feet with shallower water (i.e., less than six± feet) along the banks. Continuing to move south, depths increase from 10±feet to 15±feet over the course of approximately 0.15 mile. Continuing to move south towards SYC for approximately 0.25- mile, Mattituck Creek is approximately eight(8)feet to nine(9)feet in depth.Immediately north of SYC and in the waters adjacent to the existing office building,there are two large areas of Mattituck Creek where depths increase to greater than 25± feet. Within the channel, east of SYC, the depths are approximately 9-to-10 feet. Moving south through the water immediately adjacent to SYC and the most eastern edge of the docks,the depth is approximately seven feet. Moving closer to the bulkhead to the west, the depths decrease to two feet at low tide. Ensuring adequate depth in the channel is critical to ensure boats seeking to use SYC would have the required draft during low tide. Twi P.W. GROSSER CONSULTING, INC.

The user groups within Mattituck Creek are recreational and commercial boaters, personal watercraft (PWCs), as well as unmotorized water sports (i.e., kayaks and standup paddleboarders [SUPS]). Marinas and Boat Launches The Town of Southold indicated in the LWRP there were an estimated 3,370 to 3,530 docking facilities within the Town of Southold (Section II D-5). Specifically, within Mattituck Inlet and Mattituck Creek,the existing marinas provide approximately 300 boat slips (Section II -J Reach 1-4). There are currently three (3) marinas on Mattituck Creek, including SYC, the Strong's Water Club (also owned by SYC), and Mattituck Inlet Fishing Station. Boaters can also access Mattituck Creek via three ramps: the Mattituck Creek Waterway Access Site(owned by the NYSDEC with parking available for up to 60 cars and trailers') and two ramps on North Road Inlet (owned by the Town of Southold and Mattituck Park District). It is noted that in addition to servicing private yacht clients, SYC also provides docking slips and services for up to six (6) of the 12 commercial fishing boats that are based in Mattituck Harbor at a time. All 12 of these fishing boats are privately owned. Services available to these boats include ice, electric, pump out, and boat maintenance. Government/Public Vessels As presented in Table 1 below, it is estimated there are five government/public vessels that utilize Mattituck Creek. The Town of Southold indicates on its Marine Division website there are three patrol vessels manned year-round and several smaller vessels that operate within the creeks and inlets of the Town'. The United States Coast Guard (USCG) also has jurisdiction within the surrounding waters of the Town, and it would be expected there would be a presence within Mattituck Creek.Additionally, at the NYSDEC Mattituck Creek Water Accessway docks, Northville Docks maintains a 65-foot steel tugboat used for large oil tankers, as needed. Conservatively, it is expected government/public vessels could account for five vessels operating within Mattituck Creek. Transient Vessels/ Moorings In addition to marinas and boat launches,there is a 460-foot-by-570-foot anchorage area at the head of Mattituck Creek with a capacity of approximately 75 vessels,depending on the size (Section II-J Reach 1-5).

The anchorage is popular amongst transient vessels in the summer months. Also, the Town Trustees additionally permits private moorings within Mattituck Creek. As discussed in the LWRP,there were approximately 22 private moorings in the vicinity of Howards Creek on Mattituck Creek. Private Docks Based on 2019 aerial imagery available through Google Earth°, there are approximately 117 private docks along Mattituck Creek. The docks vary in length.At the time the LWRP was written,the private docks on Mattituck Creek could accommodate approximately 80 to 100 vessels (Section 11-J Reach 1-6). Since the LWRP's adoption it is likely additional docks have been constructed. Personal Watercraft(PWC) USCG defines PWC's as crafts measuring, "16 feet in length and designed to be operated by a person or persons sitting, standing or kneeling on the craft rather than within the confines of a hull."10 They are classified as class A inboard boats and must be registered. In New York State, a boat must be registered with the New York State Department of Motor Vehicles if it is kept in New York for more than 90 days.11 and required to be registered, just like a boat; the registration papers must be onboard while the craft is in use. The USCG states the registration number and hull identification numbers are to be visible. PWC users can access Mattituck Inlet and Creek from any public boat ramp, marinas along Mattituck Creek, and/or personal privately-owned docks. No PWC rental opportunities are offered along Mattituck Creek. Non-motorized—Kayaks and SUPS Mattituck Creek and Inlet are used for non-motorized watersports,including kayaking and stand-up paddleboarders (SUPs). Similar to PWC users, kayaks and SUP users can access Mattituck Inlet and Mattituck Creek from any public boat ramp, marinas along Mattituck Creek, and personal private docks. Members of the public can rent kayaks and SUPS from Strong's Water Club & Marina at the head of Mattituck Creek.

SYC is an authorized dealer for Sunseeker Yachts and Cruisers Yachts, as well as an authorized Volvo service center. Yachts for sale in the winter are typically stored outdoors and shrink wrapped in clear wrap which makes them more easily seen and shown. Yachts for sale in the season are shown in the water at the docks. These services require that SYC maintain machine,parts, wood, and canvas shops, as well as diesel and gas fuel sales.SYC services work orders can range from battery replacement to preventative engine maintenance, fiberglass repair, and other maintenance needs. The SYC facility is currently comprised of dockage slips, five (5) warehouse-type storage buildings for seasonal boat storage and boat maintenance, and one office/sales building.There is also one residential structure on the property where the marina manager resides. 2.1.2 Boat Characteristics at SYC The boat types serviced at SYC include sailboats, motor yachts, Express Cruisers, center consoles,sports fishing,commercial fishing,trawlers,as well as government boats for the USCG, New York State Department of Environmental Conservation (NYSDEC), Mattituck Fire Department, and others. The marina accommodates boats and yachts 18-to-133±feet in length with the majority between 40±feet to 60± feet. The typical yacht size is 50-to-86± feet in length.

Dry Dock Storage of Boats Within the five existing on-site buildings, SYC provides winter storage for 96 yachts and boats. In addition to indoor storage, SYC provides outdoor winter storage for 40 boats and yachts. The boats are hoisted from Mattituck Creek using the aforementioned travelifts, cleaned and have any maintenance requested performed, and then stored for the winter.Some smaller boats are brought to SYC via trailers on local roadways for winter storage.

Machinery, such as the travelifts and that used for boat maintenance, is used throughout the hours of operation. 2.2 Post-Develop me nt Operations and Services of SYC 2,2,1 Post-Development Operations Upon implementation of the proposed development, SYC would have two new buildings (52,500 square feet[SF] and 49,000 SF)for the sole purpose of indoor, heated storage for larger vessels (i.e., yachts). The existing storage buildings would remain the same as existing conditions and a reconfiguration of the staging areas and dry-dock storage is not proposed. Boat owners who typically store their boats in warmer climates in the winter and those looking to store their boats in climate-controlled space locally are the anticipated new yacht customers. The boats will arrive to the facility at the close of boating season (i.e., October-November) via Mattituck Inlet, be lifted from Mattituck Creek using the 85-ton travelift, be prepped for storage, and moved to the boat storage buildings. This operation would remain the same as those under existing conditions and no new equipment would be required. At the beginning of the next boating season (i.e., April-May), the boats will be removed from storage, returned to Mattituck Creek via the 85-ton travelift, and exit through Mattituck Inlet at the beginning of the boating season. It is noted the proposed two buildings would be empty during the boating season (or largely empty as some boat owners may elect not to launch their boats in a particular season). It is estimated that approximately 88 boats per season would be stored in the new buildings. Additionally, the following facility improvements are proposed: the provision of potable water via public water connection, two Innovative and Alternative On-Site Wastewater Treatment Systems (I/A OWTS) for sanitary waste management (one of which would serve as a replacement system for the current on-site sanitary system that serves the office, marina and other SYC buildings and one new system), site grading, formalization of on-site stormwater management system, landscaping, lighting improvements, and additional parking spaces to support the existing and future operations of SYC. Typical operations would continue during construction. The repair, maintenance,fueling,washing,and detailing of boats would occur in the same manner as they currently do on-site. Repair and maintenance will occur within the on- site buildings and/or at the existing dock. All materials used for such services are marine GROSSERIN LTA , INC..

It is noted that the proposed action would not alter the maximum amounts of chemicals and antifouling paint stored on-site and any spills or releases observed either on land or into the water would be required to be report in compliance with state hazardous material spill response protocol. The sale of marine fuel would continue under post-development conditions and any spills or releases observed either on land or into the water would be required to be report in compliance with state hazardous material spill response protocol. Additional information related to state spill response protocol is outlined in Section 5.4 of this report. The offering of indoor storage for larger vessels post-development is a service that is currently offered to smaller vessels at SYC. The only exception is that the type of vessels to be stored cannot be brought to SYC via trailers on roadways (which does occur with smaller vessels for winter storage) but must arrive to and leave the site via Mattituck Creek and the existing boat lift at SYC. The existing 85-ton travelift used for the existing operations is sufficient to accommodate the yachts of the proposed action. 2.2,2 Post-Development Change to Boat Slips The proposed development does not include any new boat slips nor would the existing docks be reconfigured to accommodate the proposed action. The proposed action includes indoor heated storage only, which is a specific market sector that is in high demand for yachts. 2.2.3 Post-Development Changes to Boat Volume The proposed action includes two buildings for the purpose of winter boat storage. The project does not include the use of these buildings year-round, does not propose year- round boat traffic in an out of SYC, does not propose any additional docks, nor the use of any existing facilities at SYC to house boats that arrive to the site for storage. The purpose of the project is to provide indoor, heated storage for yachts. The yachts will arrive to the facility at the close of boating season (i.e.,September-December), hauled from the water via the 85-ton travelift and transported to the heated storage buildings, and the same boats will be removed from storage, returned to Mattituck Creek via the travelift,and exit Mattituck Inlet in the beginning of the boating season (i.e., April-June). It is noted the proposed two buildings would be empty during the boating season (or largely empty as some boat owners may elect not to launch their boats in a particular season). It is estimated that approximately 88 boats per off-season would be stored in the new buildings. Accordingly,given a 12-week timeframe for entry to storage in the Fall and the same timeframe to remove boats from storage in the Spring, this equates to an average of approximately 7 boats per week or between one and two boats per day.

As such, this schedule of one-to-two boats per day can and would be controlled by SYC. With one-to-two boats per day,there would be no queuing in the Creek. As explained in Table 1 in Section 1.1.4 of this report, it is estimated that approximately 547 boats are active in Mattituck Creek on a peak season day. A peak season day likely occurs in the summer season (i.e., July or August), when temperatures are higher. The entry and return of boats to the water from storage would occur outside of this peak season day. However, even if the increase of one-to-two boats per day were to occur on a peak season day, this would equate to 0.18-to-0.36 percent increase in boat traffic, which is nominal. The proposed boat storage buildings would be available for customers who have purchased yachts from SYC and for other owners who now elect to transport their vessels to warmer climates in the winter. It is anticipated new yacht customers would come from Mattituck Inlet private docks, Greenport, Montauk, Mount Sinai, Port Jefferson, Huntington,Port Washington,Westchester County, New York,Connecticut,and Northern New Jersey. In the fall season, the yachts would be transported to SYC via Mattituck Inlet and be delivered by either SYC staff or be captained by the yacht owners or privately-hired boat captain. According to SYC, approximately 90 percent of the yachts are handled by SYC staff or for-hire captains. The remaining 10 percent are owner-operated (i.e., the yacht owner drives the vessel).All yachts would be removed from the water via the existing 85- ton travelift and placed in one of the two boat storage buildings. In the Spring,the yachts would be returned to Mattituck Creek via the 85-ton travelift and the storage buildings would be empty. The hours of operation would be the same as existing conditions. 2.2.4 Expected Yacht Types SYC currently accommodates boats and yachts that measure 18-to-133± feet in length, with the typical yacht size being 50-to-86±feet in length. The proposed two boat storage buildings would be able to store a total of 88 yachts based on an average boat size of 60± feet in length and 17± feet in beam for the winter months only. These boat storage buildings would be able to accommodate boats 50-to-86±feet maximum in length.13 All is Yachts at lengths of 87 feet or greater are stored in the water.

Engine Types and Regulations The U.S. Environmental Protection Agency (EPA) regulates exhaust and evaporative emissions for non-road spark-ignition engines, vessels, and equipment(73 FR 59034, October 8, 2008). Specifically,through Direct Final Rule published September 16, 2010(Technical Amendments for Marine Spark-Ignition Engines and Vessels), emission standards require manufacturers to control exhaust emissions from the engines and evaporative emissions from fuel tanks and fuel lines. As excerpted from the Technical Amendments, 14 "The U.S. Environmental Protection Agency (EPA) is publishing a Direct Final Rule to make technical amendments to the design standard for portable marine fuel tanks. This rule incorporates safe recommended practices, developed through industry consensus...EPA established the first-ever evaporative emissions standards for marine vessels. During their efforts to certify fuel tanks to these standards, manufacturers identified a technical issue that was not apparent before these standards were developed.

Work conducted by industry indicated that this concern applies to existing fuel tanks as well as those built to comply with EPA's evaporative emission design standard. EPA engaged the industry to identify a simple,safe, and emissions neutral solution to this fuel spillage concern. EPA has taken direct final action to make technical amendments to the design standard for portable tanks that will allow for this solution. In addition, we are incorporating safe recommended practices, developed through industry consensus, for portable marine fuel tanks. This action is emissions neutral with regard to diurnal emissions. To the extent that it helps prevent fuel spillage, incorporating safe recommended practices results in a net benefit to the environment and leads to fuel savings." The EPA also regulates emissions from marine compression-ignition (diesel) engines installed in marine vessels, ranging in size and application from small recreational vessels to large ocean-going vessels under various federal rules (including 40 CFR 1042 [Tier 3 and 4 engines],40 CFR 1068 [General Compliance], 40 CFR 89 [Tier 1 and 2 below 37 kW], and 40 CFR 94 [Tier 1 and 2 at or below 37 kW]).15 The EPA domestic emission standards apply to marine diesel engines installed on all U.S.vessels, and are applicable to the design at the manufacturer level. For the new vessels that are expected to utilize SYC for storage, it must be assumed that all vessels comply with the prevailing federal regulations for the engine types on board. s https://www.epa.goy/regulations-emissions-vehicles-and-engines/domestic-regulations-emissions-marine-compression MEN P.W.

Some of the correlating data along with a brief explanation of its purpose and role in water quality are described below. It should be noted that several of the indicators are influenced by seasonal changes, such as dissolved oxygen,temperature, etc. and are not indicative of any actions taken by the Applicant. It is noted that the data collected is not analyzed and summarized by SCDHS. To understand how the SCDHS data and subsequently, the overall health of Mattituck Inlet and Mattituck Creek compares to the health of Long Island Sound,the contributing water body for Mattituck Inlet and Mattituck Creek, the Long Island Sound Study (LISS) was reviewed.17 The LISS partnership was formed in 1985 between the EPA and the States of New York and Connecticut in a cooperative effort to restore the health of Long Island Sound and its overall ecosystem. The Comprehensive Conservation and Management Plan (CCMP) was first developed in 1994 with updates in 2015 and 2020 to create ecosystem targets for reducing nitrogen loads, habitat restoration, public involvement and education, and water quality monitoring. Of relevance is the Water Quality Index, which is part of the LISS and combines several water quality measurements to rate overall water quality in the Long Island Sound. The Water Quality Index builds upon the EPA National Coastal Assessment(NCA) Index which identifies low levels of Nitrogen, Phosphorous and Chlorophyll-a,and high concentrations of Dissolved Oxygen (DO) as indicators of good water quality annually. Mattituck Harbor is located in the eastern basin and therefore those parameters were reviewed.18 Between 1991 and 2011,data collected for the eastern basin consistently had water quality ratings of good to fair. The water quality in the eastern basin is flushed more often due to its proximity to the Atlantic Ocean. As discussed later in Section 3.1.2 of this report, Mattituck Creek was closed in 2012 due to saxitoxin found in shellfish and was not reopened to shellfishing until April 2014. Higher levels of Nitrogen and Chlorophyll-a during this time period were indicative of a water quality issue event. The data from SCDHS related to Total Nitrogen,Total Phosphorus,Chlorophyl-a,Dissolved Oxygen, and Secchi depth were compared to the benchmarks set forth in the LISS.

Nitrogen enters water bodies through both point sources, such as wastewater treatment or industrial plants, and non-point sources, such as stormwater runoff and septic systems. Although nitrogen is important for plants and aquatic organisms, too much nitrogen can yield high amounts of algae and low levels of dissolved oxygen. Concentrations vary seasonally, spatially and with depth, and based on the time of day. Capturing total nitrogen is beneficial as it includes all available forms of nitrogen. For the LISS, trade equalization was calculated to determine the effect one pound of nitrogen leaving a wastewater treatment plant and when it would reach Long Island Sound. This method addresses the fact that some of the nitrogen within embayment's, such as Mattituck Harbor, retain some of the nitrogen and not all reaches Long Island Sound. The transfer efficiency and river attenuation are multiplied together to determine the trade equalization. For Management Zone 11E, where SYC is located, the trade equalization is 0.55.19 Therefore, for every pound of nitrogen introduced into Mattituck Harbor, 45 percent remains within Mattituck Harbor and the other 55 percent reaches Long Island Sound.Within the last ten years, nitrogen discharges to water bodies have declined as more sophisticated treatment methods are implemented at wastewater treatment plants. Total Nitrogen for Bay Station 055320 between 2012 and 2020 was 0.3 mg/L and the overall total Nitrogen for Mattituck Inlet and Mattituck Creek was 0.4 mg/L. The Nitrogen levels are consistent with the overall trend of Mattituck Harbor and LISS. Based on the LISS, the Nitrogen levels would be fair to good. ➢ Total Phosphorus - Phosphorous levels in water can contribute to Harmful Algal Blooms(HABs) if too high and contribute to poor water quality. Phosphorous can have a comparable impact to water quality as nitrogen.The majority of readings at Bay Station 055320 did not detect phosphorous and between 2012 and 2020 the level was 0.06 mg/L. Overall, for Mattituck Harbor between 2000 and 2020, the total phosphorous level was 0.1 mg/L. Low levels of phosphorous and ortho-phosphate lends to well-oxygenated bodies of water.

Some of the algae can produce toxins that can be harmful to humans. Higher levels of Chlorophyll-a can lead to lower levels of dissolved oxygen. Pursuant to the Suffolk County Subwatersheds Wastewater Plan, 5.5 ug/L was selected for Long Island Sound tributaries. Between 2012 and 2020,the average Chlorophyll-a level was 7.3 ug/L. Overall, for Mattituck Harbor, the Chlorophyll-a level was 5.8 ug/L. While Bay Station 055320 may be higher than the Mattituck Harbor average, the concentrations followed typical seasonal trends. Based on the conditions set forth for the LISS (5 ug/L and 20 ug/L), the Chlorophyll-a levels for both Bay Station 055320 and Mattituck Harbor would be fair to good. ➢ Dissolved Oxygen — Dissolved oxygen (DO) is a significant water quality concern in Suffolk County. DO levels are important in the health of the water body overall as they correlate to whether an aquatic species could thrive in the water body. The LISS defines hypoxia as "dissolved oxygen concentrations below 3 milligrams of oxygen in each liter of water (mg/L). Below that level, the supply of oxygen in the water is inadequate to support healthy populations of estuarine organisms" (page 11).According to the LISS, levels of DO of 5.0 mg/L and higher are generally accepted as being protective of the Sound's estuarine life.20 The average DO level for Bay Station 055320 was 9.2 mg/L. The 20-year average DO level for Mattituck Harbor was also 9.2 mg/L." Based on the conditions set forth for the LISS(2 mg/L and 5 mg/L),the DO levels for both Bay Station 055320 and Mattituck Harbor would be fair to good. ➢ Secchi—Secchi depth is an important indicator of water quality as greater clarity of the water and light penetration typically indicates a water body is healthy. Pursuant to the water clarity ecosystem target and supporting indication from the LISS, water clarity is ranked as follow": 20 https://Iongislandsoundstudy.net/about/our-mission/management-plan/hypoxia/ 21 It is noted that,according to 6 NYCRR 703.3,the average daily ambient water quality standards for DO for Class SA,SB and SC waterbodies are 4.8 mg/L with allowable deviations no less than 3.0 mg/L for short periods of time. https://govt.westlaw,com/nvcrr/Document/14ed9O412cd 17lldda432a ll7e6eOf345?viewTVpe=FuliText&originationContext=docum enttoc&transitionType=CategoryPageltem&contextData=(sc.Default) 22 https://Iongislandsoundstudy.net/ecosystem-target-indicators/water-clarityP.W.

The modeling completed as part of the SWP indicates that resulting MCL concentrations could be below both the Article 6 and New York State MCL densities if implemented on a County-wide level as well as provide benefits to groundwater. Furthermore,the SWP provides additional nitrogen reduction recommendations through the Long Island Nitrogen Action Plan (LINAP), estuary plans, and individual Town/Village initiatives. With regards to establishing nitrogen load criteria within specific subwatersheds,the SWP identified 28 marine and mixed water bodies which achieved all water quality standards and ecological endpoints proposed in the SWP, as discussed below in this section of the report. These larger subwatersheds are identified as reference water bodies within the SWP, to which the smaller subwatersheds contribute.

The SWP established ecological endpoints to determine nitrogen load reduction goals for all subwatersheds. The following were evaluated to correlate to nitrogen loads within Mattituck Creek: DO, Chlorophyll-a, presence/absence of HABs, and Secchi depth (page 2-82).A long-term objective of the SWP is to minimize the number of times DO levels are below the NYSDEC's acute standard of 3.0 mg/L(page 2-77)for the reference water body. The desired ecological endpoint for DO levels is to be greater than the NYSDEC's daily average of 4.8 mg/L. With regards to Chlorophyll-a concentrations, less than 5.5 ug/L in 90 percent of all samples collected was selected by SCDHS and other contributors to the SWP for Long Island Sound tributaries. A Secchi depth of two meters was chosen as well as that depth is protective of eelgrass per the Final Report of the New York State Seagrass Task Force, 2009. HABs were categorized as the number of events per year where cyanobacteria exceeded 25 ug/L, Alexamdrium fundyense exceeded 1,000 cells/L, or Dinophysis acuminate exceeded 10,000 cells/L (page 2-67) and for the reference water body, no HABs with primarily health impacts could have occurred within the last 10 years and a maximum of one HAB with primarily environmental impacts in the last 10 years. The SWP anticipates the following improvements to be made within the subwatershed to reduce nitrogen: improving HAB/DO conditions by 32 percent and reduce Chlorophyll-a by 59 percent(page 2-220). Based upon the Suffolk County's recent groundwater models developed for LINAP, the local groundwater flow direction beneath the site is generally to the east and north, towards Mattituck Creek and the Long Island Sound.

Among other things, the CCMP creates ecosystem targets for reducing nitrogen loads, restoring habitat, public involvement, education, and water quality monitoring. The following summarizes the ecosystem targets included in the 2020-2024 LISS Update(page 20) (in italics) and the status of the target is provided, as excerpted from the Long Island Sound website on the Water and Watersheds Ecosystem Targets and Indicators discussion:21 • Extent of Hypoxio: Measurably reduce the area of hypoxia in Long Island Sound from pre-2000 Dissolved Oxygen TMDL averages to increase attainment of water quality standards for dissolved oxygen by 2035, as measured by the five-year running average size of the zone. Currently, the target is ahead of schedule. However, further reductions in hypoxic areas area required in order to meet the target. • Nitrogen Loading:Attain Wastewater Treatment Facility nitrogen loading limits at the 2000 Dissolved Oxygen TMDL allocation level by 2017 and maintain the loading cap. Have practices and measures instituted to attain the allocations forstormwater and nonpoint source inputs from the entire watershed by 2025. The initial target to reduce nitrogen loads discharged to Long Island sound from wastewater treatment plants was met by 2017. As of 2020, nitrogen loads decreased by 2,959 pounds per day from the previous baseline of 59,000 pounds per day into Long Island Sound from New York and Connecticut. No data is available regarding the status of the target for 2025 regarding stormwater and non-point source inputs. There are currently no wastewater treatments plants on Mattituck Harbor. • Water Clarity: Improve water clarity by 2035 to support healthy eelgrass communities and attainment of the eelgrass extent target. 25 https://longislandsoundstudy.net/target-indicator-type/clean-waters-and-healthy-watershedsP.W.

As of 2017, the Eastern Long Island Sound basin had an average depth of water clarity of 3.2 meters (approximately 10.5 feet), which ranked it in the A-to A+grading. • Impervious Cover: Through green infrastructure, low impact development,and storm water disconnections, decrease by 10 percent the area of effective impervious cover in the Connecticut and New York portions of the watershed by 2035 relative to a 2010 baseline. This target is behind schedule and impervious cover increased instead of decreasing. To meet this target, green infrastructure needs to be encouraged. • Riparian Buffer Extent: Increase the percent area of natural vegetation within 300 feet of any stream or lake in the Connecticut and New York portions of the Long Island Sound watershed to 75 percent by 2035 from the 2010 baseline of 65 percent. This target is behind schedule and requires an increase in riparian buffer of 0.4 percent per year between 2010 and 2035. • Approved Shellfish Areas: Upgrade 5 percent of the acreage restricted or closed for shellfishing in 2014 by 2035. This target is behind schedule as shellfish areas in both Connecticut and New York are unable to be upgraded at the rate required due to more frequent administrative closures and water quality issues impacting shellfish growing areas.Several shellfish areas have been downgraded as locations could not be sampled in an appropriate manner to be maintained as active growing areas and led to closures due to administrative constraints. In New York between 2015 and 2018, 364 acres of shellfish area were upgraded. It is important to note that in New York, shellfish areas are closed when there is over three inches of rainfall during a seven-day period as it can temporarily impair water quality. • Sediment Quality Improvement:Reduce the area of impaired sediment in Long Island Sound by 20 percent by 2035 from a 2006 baseline. 16 P.W.

The number of sampling stations on Long Island is too low to be determined statistically significant. Between 1991 and 2011, data collected for the eastern basin consistently had water quality ratings of good to fair. These findings are consistent with the data collected by SCDHS for Mattituck Inlet and Mattituck Creek, as presented in Section 3.1.1 of this report. However, as indicated in Section 3.1.2 of this report and in the SWP on page 5- 12, "the water quality is generally poor with occasional HABs (primarily Mattituck Inlet/Creek), poor water clarity and low dissolved oxygen.,'2'As such, based on the water quality observed during the preparation of the SWP, high nitrogen reduction goals were set to achieve ideal water quality—which for Mattituck Creek was set at a 66 percent. 3.1.4 Shellfishing and Shellfish Restoration in Mattituck Inlet and Creek New York State Department of Environmental Conservation (NYSDEC)Shellfish Closure Map As discussed above in Section 3.1.3, NYSDEC conducts sampling within Shellfishing areas to assess water quality which ensures the conditions are within the parameters for safe human consumption of shellfish.The criteria for ensuring safe consumption are set forth in the National Shellfish Sanitation Program (NSSP) Guide for the Control of Molluscan Shellfish published by the U.S. Food and Drug Administration.27 The NSSP requires that for dilution analyses performed in waters adjacent to marinas, fecal coliform loading greater than 14 fecal coliform MPN per 100 milliliters (mL), the waters adjacent to the marina should be conditionally approved, restricted, conditionally restricted, or prohibited (page 59). If the dilution analysis is less than or equal to 14 fecal coliform MPN per 100 mL, the waters adjacent to the marina should be approved or conditionally approved by the regulatory agency. Based on the criteria presented above, NYSDEC regulates the closure of shellfish lands for sanitary concerns in New York at 6 NYCRR Part 41(Sanitary Conditions on Shellfish Lands) of the New York State Code. Section 41.3 (Shellfish Lands in Suffolk County) specifically details closures of shellfish lands in Suffolk County: "shellfish lands in Suffolk County[that] are in such sanitary conditions that shellfish thereon shall not be taken for use as food 26https://suffolkcountyny.gov/Portals/0/formsdocs/planning/CEQ/2020/SWP%20FINAL%2OJuly%202020.pdf Z'https://www.fda.gov/media/143238/download P.W.

Town of Southold Trustees—NYSDEC Water Quality Data for Shellfishing Through the Town of Southold website, a request for public records was submitted on June 8, 2021 to obtain the NYSDEC Water Quality Data for Shellfishing for the years 2012 through 2020. On June 10, 2021, the Town indicated that the requested records were unavailable (see Appendix D of this report). History of Shellfish Closures in Mattituck Creek Since the 1980s, Mattituck Creek's shellfishing areas have been routinely closed due to water quality issues. Water quality issues over the decades have been attributed to stormwater runoff into the creek in addition to fluctuations in dissolved oxygen influenced by water temperature changes and nutrients introduced into the creek, as discussed above in Section 3.1. Since 1995, the Town Board of Trustees and NYSDEC began collecting water quality data to determine changes in Mattituck Creek.30 In an effort to pinpoint sources of pollution into Mattituck Creek and encourage NYSDEC to modify shellfish area closures at that time, the Town Board of Trustees constructed a drainage system within Bayview Avenue on the west side of Mattituck Creek, located south of SYC,to assess if water quality improved when runoff was not introduced into the water.The system was successful to reduce pollution from entering Mattituck Creek and water quality improved and NYSDEC began to reopen shellfish areas conditionally.31 NYSDEC has periodically reopened portions of Mattituck Creek for shellfishing since 2000. The stipulation for remaining open to shellfishing was that no more than three inches of rainfall could accumulate over seven consecutive days. In April 2012, 92 acres of Mattituck Creek were closed for shellfishing due to the presence of saxitoxins, which are harmful to humans if consumed, and are a result of toxic algal blooms.32 As indicated in the SWP, as discussed in Section 3.1.2,there are four HABs monitored within the marine water bodies of Suffolk County: brown tide (Aureococcus anophagefferens),two types of 29 https://www.dec.ny.gov/outdoor/7765.html so https://suffolktimes.timesreview.com/2014/01/dec-declares-mattituck-creek-ok-for-shellfishing/ si Ibid. sz https://www.newsday.com/long-island/suffolk/dec-shuts-shellfish-harvesting-in-southold-1.3644504 P.W.

Toxic blooms like these are closely related to warmer weather and occur almost annually in Long Island's waters and research reviewed did not indicate their occurrence correlates to boating activity on marine waters.This was the first time NYSDEC closed Mattituck Creek to shellfishing since 2006, when the first large-scale shellfishing closure was enforced by NYSDEC due to a harmful algal bloom. Mattituck Creek was not reopened to shellfishing until April 2014.33 Cornell Cooperative Extension (CCE) Floating Upweller System (FLUPSY) Program Strong's Marine has had an active relationship with the Cornell Cooperative Extension (CCE) for over 30 years, commencing at its Mattituck Bay location, and in 2017, upon acquisition of SYC property, became a designated host for the CCE Marine Program shellfish restoration program, Floating Upwelling Systems (FLUSPYs). A portion of SYC's dock was turned into a shellfish nursery to support eight (8) FLUSPYs. These FLUPSYs enable 600 gallons of water per minute to be passed through the millions of juvenile clams housed in these systems, leading to improved water quality (see Memorandum of Understanding Between Cornell Cooperative Extension of Suffolk County and Strong's Yacht Center,June 5, 2019 in Appendix C of this report). According to SYC, as a host,the CCE Marine Program has enabled approximately 6 million clams to be grown at the marina over the last year(and over 10 million in the last four years).A minimum of approximately 1.5 million clams per year are expected to be harvested from the FLUPSY units at SYC. Once harvested,the clams are relocated to a NYSDEC-designated sanctuary site pursuant to the Long Island Shellfish Restoration Program (LISRP).Additionally,SYC has committed to being a FLUPSY host through 2030. As a FLUPSY host SYC additionally provides the funding to the CCE Marine Program to operate and maintain the units.As clams are filter feeders,they capture and digest suspended particles as water passes through them. This aids in improving water quality as excess nutrients are removed from the water.31 According to CCE, the Mattituck Inlet has proven to be the best location for growth rate in Southold Town and the FLUPSY site at SYC is integral to shellfish restoration on Long Island. ®2 Potential Impacts to Surface Water Quality 3.2.1 Post-Development Operations The proposed action includes the construction of two boat storage buildings to support its current operations and market demand for indoor, climate-controlled storage in the 33 Ibid. 34 https://shellfish.ifas.ufl.edu/environmental-benefitsP.W.

The proposed action does not include or require any dredging or bottom sediment disturbance as the expected yachts to be stored on-site are of a size and type that are currently using the Inlet. Furthermore,SYC is equipped with the necessary launch and boat lift(i.e.,travelifts) required.The existing dock configuration and the FLUPSY unit operations and agreement would all remain. It is also noted that the proposed action includes improvements to on-site sanitary disposal methods and stormwater management. As indicated in Section 2.2.1, the on- site sanitary system would be upgraded pursuant to Article 6 of the Suffolk County Sanitary Code and also aligns with goals related to nitrogen reduction set forth in the SWP and LISS. The proposed action includes two I/A OWTS, one replacement for an existing on-site sanitary system and one new system. An I/A OWTS is permissible as an on-site decentralized wastewater treatment system that, at a minimum, is designed to reduce total nitrogen in treated effluent to 19 mg/L.As discussed in Section 3.1.2 above,the SWP indicates that an I/A OWTS system is assumed to remove an average of 70 percent of the influent nitrogen concentration and that the removal efficiency of 1/A systems will increase as new technologies emerge and the market demand for these systems in Suffolk County increases (2-104).35 Additionally,the proposed action includes the installation of drainage controls to accommodate and recharge stormwater on-site(see Section 3.3.6 of this report). The sources reviewed as part of the analysis completed in Section 3.1 of this report did not identify the boating industry as a contributor to the degradation of surface water quality for Mattituck Creek or Long Island Sound.As the proposed action would introduce an imperceptible number of new boats and yachts to Mattituck Creek and Long Island Sound, it is not anticipated the proposed action would introduce new risks to surface water quality. 3.2.2 Increased Yacht Traffic SYC estimates approximately 88 yachts to be stored within the two proposed buildings, and some of these yachts are expected to already use the Inlet. As indicated in Section 2.2.2 of this report, given a 12-week timeframe for entry to storage in the Fall and the same timeframe to remove the yachts from storage in the Spring, this equates to an average of approximately 7 boats per week or one-to-two boats per day. 35https://suffolkcountyny.gov/Portals/0/formsdocs/planning/CEQ/2020/SWP%20FINAL%20July%202020.pdP.W.

These types of vessels are serviced and maintained professionally throughout the season. Due to the sizes and insurance requirements,these types of yachts are also typically captained by licensed USCG captains that are fully trained, experienced, and capable of maneuvering these types of vessels (i.e.,the majority of yacht owners do not captain their own vessels).As such,the 88 boats that are expected to travel to and from SYC upon implementation of the proposed project would be properly navigated in the Inlet. 3.2.3 Environmental Discharge Data for New Yachts As indicated in Section 2.2.5 of this report, all boats and yachts that arrive to SYC are assumed to be in operable condition, with no discharges of gray or black water from holding tanks, and no fuel leaks or heavy exhaust, for the safety of the captain and any other persons aboard. It is also noted that the USACOE maintains the navigability of Mattituck Harbor for the recreational and commercial boating industry, as an important commerce industry to the federal government. Further noted is the presence of the United States Coast Guard and the Southold Bay Constable (see Section 5.0—Monitoring and Enforcement of this report) for the sole purpose of safe navigation and use of the Mattituck Creek and Inlet, including vessels that may be exhibiting leaks, fumes, heavy exhaust, etc. 3.2.4 Engine Types and Regulations As indicated in Section 2.2.5 of this report,for the vessels that are expected to utilize SYC for storage, it is anticipated that all vessels will comply with the prevailing federal regulations for the engine types on board.Accordingly,there would be no adverse impact to the water quality of Mattituck Creek and Inlet. 3.2.5 No Discharge Zone All boaters utilizing Mattituck Harbor and the Long Island Sound are responsible for understanding that these areas are No Discharge Zones for sewage (i.e., no discharge of sewage from boats may take place). All sewage must be held in on-board holding tanks and are to be emptied either at a pump station or by a pump-out boat. For vessels arriving to SYC for storage, all holding tanks would be emptied by SYC's pump-out boat. 3.2.6 Proposed Stormwater Controls Under existing conditions, as a facility that has existed in its current state for 60 years, there are few existing drainage structures (controls) on the site. There are few grates/drainage inlets and in other areas, stormwater infiltrates through existing lawn P.W.

PAG CLIENT DRIVEN SOLUTIONS areas or gravel surfaces. On the vegetated uplands, stormwater is recharged naturally through infiltration. As part of the proposed action, drainage controls would be provided on-site. The Town of Southold regulates stormwater management and discharge associated with land- disturbing activities and projects that involve a replacement of or addition to impervious surfaces, under Chapter 236 in the Town Code. Pursuant to §236.16(A), all development, construction, excavation, and landscaping activities are to be conducted in accordance with an approved stormwater management control plan. The proposed action includes the installation of on-site leaching pools, French drains, and the use of pervious gravel as stormwater management methods in the project area. Four (4) tributary areas are proposed to be constructed within the area of disturbance to capture stormwater runoff from the proposed buildings and the western side of Building 7 and all of Building 8. The proposed stormwater management plan is designed to accommodate a two-inch rain event, in accordance with Town of Southold regulations (Chapter 236 Stormwater Management). 3.2.7 Proposed Erosion and Sedimentation Controls During construction activities, there is the potential for erosion and sedimentation with prolonged soil exposure and fugitive dust during dry periods. To minimize the potential for erosion and sedimentation, an Erosion and Sediment Control Plan has been prepared and included in the DEIS,which includes,at minimum,stockpile protection,inlet sediment control devices for storm structure protection, silt fencing, minimizing the extent and duration of exposed areas, and the construction and maintenance of a stabilized construction entrance to prevent soil and loose debris from being tracked onto local roads. All erosion and sediment control measures will be routinely inspected and maintained such that no sediment would be transported off-site. The proposed action would require coverage under the SPDES General Permit for Stormwater Discharges from Construction Activity (GP-0-20-001), which includes the preparation of a Stormwater Pollution Prevention Plan (SWPPP) for submission to both the Town and the NYSDEC prior to any construction activity. The SWPPP would be designed in accordance with the New York State Stormwater Management Design Manual and would meet the standards and specifications of the New York Standards and Specifications for Erosion and Sediment Control. Furthermore, the proposed stormwater management system and sediment and erosion controls to be implemented would be consistent with Chapter 236, Stormwater Management and Erosion and Sediment Control, of the Town Code.

Within the Tidal Wetlands Permit, the NYSDEC set forth conditions for erosion and sedimentation controls, and protection of adjacent wetlands and waterways, for which SYC and its construction managers will comply with and are assumed to be subject to inspection by the NYSDEC during construction of the proposed project. The permit expires January 30, 2025. Based on the above, the proposed action includes the requisite measures and methods to prevent erosion and sedimentation during construction. P.W.

Specifically, at the southeast portion of the site is Intertidal Marsh (IM) and along the eastern boundary is the Littoral Zone (LZ). The existing bulkhead is also visible. In June 2017, a tidal wetland delineation was performed by En-Consultants in June 2017 (see NYSDEC Approved Plans in Appendix C of the DEIS). The delineation is generally consistent with the boundary lines on the NYS Tidal Wetlands Map. The proposed action was reviewed by the NYSDEC and a Tidal Wetlands Permit (Permit ID 1-4738-01843/0028) and a Non-Jurisdictional Determination were issued on January 31, 2020. As indicated in the Tidal Wetlands Permit, the regulated activities include the installation of two dry wells/leaching pools,addition of a French drain system to the west side of Building 7 (an existing one-story building) and maintaining gravel for all roadway and parking areas. NYSDEC confirmed that based on the survey prepared by Young & Young Engineering dated January 2, 2020, all activities landward of the 10-foot contour line are outside the jurisdictional limit and are not subject to permitting. As the proposed action would be implemented in accordance with the Natural Resource Permit Conditions and General Conditions set forth in the Tidal Wetlands Permit, no significant adverse impacts to State-regulated wetlands would be expected.

As excerpted from the website of the Town of Southold Bay Constable,36 "The Marine Division is staffed by three full-time bay constables. It is tasked with patrolling Southold Town's shoreline with the Long Island Sound and the Peconic Bay, along with its many inlets, harbors, and creeks. This unit is equipped with three 26-to 27 foot patrol vessels that are manned year-round and several smaller vessels for work within the smaller creeks and inlets. Among its responsibilities is the enforcement of the Navigational Law, Environmental Conservation Law, and Southold Town Codes, including shellfish, wetlands,boats and beaches. This division also provides marine search and rescue, beach patrol, and Homeland Security patrols." 5.2 Boat SpeedLimit i in Mattituck Inlet and MattituckCreek The entirety of Mattituck Creek is a 5 mph (no wake) zone,which is strictly enforced by the USGC and the Bay Constable. Signage is posted along the channel. 5.3 Town of Southoldo Code Chapter 96-8 Sanitary Regulations As excerpted from §96-8 Southold Town Code,the following is an enforceable policy: "The dumping of oil, refuse, garbage, sewage or waste is prohibited."37 Therefore, the Town's enforceable code would prohibit such behaviors by vessels SYC has a responsibility to make all user groups aware of this policy and boat operators would be expected to adhere to the requirements. 5.4 Town of Southold Town Code Chapter 96-13 SpeedLimits, Manner of Operation Regulations As excerpted from §96-13 of Southold Town Code,the following is an enforceable policy: A.

C. Except where lower maximum speed limits have been posted, no boat shall be operated in excess of 45 miles per hour in the waters of the Town of Southold. D. No boat shall be operated in such a manner as to throw up a wake which could be dangerous to life or limb of a person, boat or other property.38 Boat operators have a responsibility to abide by posted speed limits. It would be expected user groups of SYC would maintain appropriate boat speeds within waters of the Town of Southold and within Mattituck Inlet and Mattituck Creek. There are ramifications such as speeding tickets, fines, and the revocation of license for failure to adhere to posted speed limits. 5.5 New York State Department of Environmental Conservation Spills Hotline As excerpted from the NYSDEC website39, "Accidental releases of petroleum, toxic chemicals, gases, and other hazardous materials occur frequently throughout New York State. Even small releases have the potential to endanger public health and contaminate groundwater, surface water, and soils. ...The public can notify DEC of releases to the environment by calling the NYS Spill Hotline." SYC and all vessels have a responsibility to report any spills that are observed on-site and in the water. Based on the local,State, and Federal monitoring and enforcement measures in place,the proposed action would not impact or alter the existing measures in place. Furthermore, the proposed action would not require new monitoring and enforcement measures to be implemented. 38 htt s: ecode360.com 5157699 39 https://www.dec.ny.gov/chemical/8428.htm1. P.W.

WITNESSETH: WHEREAS, Governor Andrew Cuomo initiated and announced funding for the Long Island Shellfish Restoration Project("LISRP") for the purpose of enhancing natural stocks of hard clams and eastern oysters throughout the Long Island region, and establish self-sustaining populations and help improve water quality. WHEREAS, the CCE Marine Program has been working with shellfish aquaculture and resource enhancement for more than 30 years and has the staff, experience and facilities to undertake large- scale shellfish restoration efforts involving the public. WHEREAS, The Governor recognized the unique abilities of CCE and directed the New York State Department of Environmental Conservation("NYSDEC") to enter into a contract with CCE to spawn, grow-out and plant millions of clams and oysters throughout Long Island as part of the LISRP. The State Comptroller's Office determined that CCE is a sole source provider of such services. WHEREAS, The most efficient method for grow-out of seed clams is using floating upwelling systems, ("FLUPSY") which resemble floating docks that hold shellfish seed in barrels supported below the floating structure. WHEREAS, CCE is seeking active partners to host FLUPSYS throughout Long Island to help meet the goals of the LISRP. WHEREAS, Each FLUPSY requires a protected area where they can be tied to a fixed or floating structure, space of at least 13 feet by 13.5 feet, minimum of 3 feet deep at low tide, a source of power, running water for washing and ready access by CCE staff and volunteers for maintenance. NOW THEREFORE, in consideration of the mutual covenants and conditions herein set forth, the parties agree as set forth above and as follows: 1 Article A. CCE's activities and responsibilities: CCE shall: l. Identify one person who will be the primary contact for all activities relative to this effort and provide additional emergency contacts. 2. Be responsible for obtaining the necessary regulatory permits from the NYSDEC as well as any other regulatory authorities to allow for the grow-out of shellfish at the Partner's site for the purposes and duration of this project. 3. Be responsible for siting up to ten (10) FLUPSYS at Partner's facility/property, located at 5780 West Mill Road,Mattituck,New York,ensuring location is suitable for clam growth and survival relative to water quality, depth and other factors. 4. Be responsible for delivery and installation of the FLUPSYS, as well as removal of the FLUPSYS at the end of the season and/or project. Assistance from the host Partner is encouraged,but not required. 5. Provide signage for the FLUPSYS as a means to educate the public about shellfish biology and enhancement and acknowledge the contribution from the Partner towards achieving the goals of the LISRP. CCE will produce additional outreach materials for the same purpose. 6. Compensate the Partner for electricity and the utilization of dock slips. The dock slips coordinates are Latitude: 41' 0'23.25"N Longitude: 72°32'51.77"W (See attached FLUPSY site location map). The cost of the electricity and dock slips will be $10,715.00 to be payable upon deployment of the FLUPSYS and receipt of an invoice from the Partner. 7. Be responsible for the FLUPSY's structural maintenance. 8. Be responsible for the care of clams including cleaning, sorting, and counting. 9. Be responsible for ensuring, to the best of our ability, that the FLUPSYS are safe and its doors are kept closed and locked in order to maintain a safe environment. 10. Ensure that FLUPSYS are kept in a clean and orderly fashion and that no equipment will be left on the deck which could constitute a hazard when CCE staff and/or volunteers are not present at the site. 2 Article B.
