Assessment Form 1997 1416-2 (9195)-7c 617.20 SEAR Appendix A State Environmental Quality Review FULL ENVIRONMENTAL ASSESSMENT FORM Purpose: The full EAF is designed to help applicants and agencies determine, in an orderly manner, whether a project or action may be significant. The question of whether an action may be significant is not always easy to answer. Frequent- ly, there are aspects of a project that are subjective or unmeasureable. It is also understood that those who determine significance may have little or no formal knowledge of the environment or may not be technically expert in environmental analysis. In addition, many who have knowledge in one particular area may not be aware of the broader concerns affecting the question of significance. The full EAF is intended to provide a method whereby applicants and agencies can be assured that the determination process has been orderly, comprehensive in nature,yet flexible enough to allow introduction of information to fit a project or action. Full EAF Components: The full EAF is comprised of three parts: Part 1: Provides objective data and information about a given project and its site. By identifying basic project data, it assists a reviewer in the analysis that takes place in Parts 2 and 3. Part 2: Focuses on identifying the range of possible impacts that may occur from a project or action. It provides guidance as to whether an impact is likely to be considered small to moderate or whether it is a potentially- large impact. The form also identifies whether an impact can be mitigated or reduced. Part 3: If any impact in Part 2 is identified as potentially-large, then Part 3 is used to evaluate whether or not the impact is actually important. DETERMINATION OF SIGNIFICANCE—Type 1 and Unlisted Actions Identify the Portions of EAF completed for this project: a Part 1 EX Part 2 IUPart 3 Upon review of the information recorded on this EAF(Parts 1 and 2 and 3 if appropriate), and any other supporting information, and considering both the magnitude and importance of each impact, it is reasonably determined by the lead agency that: Z A. The project will not result in any large and important impact(s) and, therefore, is one which will not have a significant impact on the environment, therefore a negative declaration will be prepared. ❑ B Although the project could have a significant effect on the environment, there will not be a significant effect for this Unlisted Action because the mitigation measures described in PART 3 have been required, therefore a CONDITIONED negative declaration will be prepared.' ❑ C. The project may result in one or more large and important impacts that may have`a significant impact on the environment, therefore a positive declaration will be prepared.

The reviewer is not expected to be an expert environmental analyst. • The Examples provided are to assist the reviewer by showing types of impacts and wherever possible the threshold of magnitude that would trigger a response in column 2.The examples are generally applicable throughout the State and for most situations. But,for any specific project or site other examples and/or lower thresholds may be appropriate for a Potential Large Impact response,thus requiring evaluation in Part 3. • The impacts of each project. on each site, in each locality, will vary. Therefore, the examples are illustrative and have been offered as guidance.They do not constitute an exhaustive list of impacts and thresholds to answer each question. • The number of examples per question does not indicate the importance of each question. • In identifying impacts, consider long term,short term and cumlative effects. Instructions(Read carefully) a. Answer each of the 20 questions in PART 2.Answer Yes If there will be any impact. b. Maybe answers should be considered as Yes answers. c, If answering Yes to a question then check the appropriate box(column 1 or 2)to Indicate the potential size of the Impact. If Impact threshold equals or exceeds any example provided, check column 2. If Impact will occur but threshold Is lower than example,check column 1. d. Identifying that an Impact will be potentially large(column 2)does not mean that It Is also necessarily significant. Any large Impact must be evaluated In PART 3 to determine significance.Identifying an impact In column 2 simply asks that It be looked at further. e. If reviewer has doubt about size of the impact then consider the Impact as potentially large and proceed to PART 3. f. It a potentially large impact checked In column 2 can be mitigated by changes)In the project to a small to moderate Impact,also check the Yes box In column 3.A No response indicates that such a reduction Is not possible.This must be explained In Part 3. 1 23 Small to Potential Can Impact Be Moderate Large Mitigated By IMPACT ON LAND Impact Impact Project Change 1.

Summary A. DESCRIPTION OF THE PROPOSED ACTION This action involves the Suffolk County Water Authority's acquisition of a portion of the Village of Greenport(hereinafter also referred to as "Greenport")public water supply system and operating plant located outside the legal boundaries of the village together with the 300,000 gallon elevated water storage tank located within the village boundaries. (A copy of the contract of sale is attached as Appendix A.) Greenport will retain ownership and control of the water supply system and operating plant within the village boundaries. Greenport will have the option of supplying its own water and/or of purchasing water from the Suffolk County Water Authority(hereinafter also referred to as "SCWA") at a wholesale rate. The facilities to be acquired include approximately 41 miles of water main ranging in size from 4-inch to 12-inch,seven operating water plants with twelve potentially active wells all of which have the mechanical capacity to produce 3,800 gallons per minute of water, 326 fire hydrants, one elevated steel 300,000 gallon storage tank and 2,080 residential and commercial customers. The facilities to be retained by Greenport include all customers,water mains and appurtenances within the village boundaries,three water plants located within the village boundaries and one water plant with two 15,000 gallon hydropneumatic tanks located outside the village boundaries. B. POTENTIAL BENEFICIAL AND ADVERSE IMPACTS Potential beneficial impacts identified in Part II include improvement of the quality and quantity of public water supply which will be beneficial to public health and fire fighting capability. Potential adverse impacts identified in Part II include impacts to groundwater, agricultural land resources, Southold Special Groundwater Protection Area and growth and character of community or neighborhood. It is important to note that the potential adverse impacts identified in Part II exist in the operation of the Greenport system whether or not it is acquired by SCWA. As discussed herein,SCWA's significant additional financial resources,its experienced and adequate staff,its state of the art drinking water laboratory and its SCADA system are likely to facilitate the proper management and operation of the Greenport system. C. MATTERS TO BE DECIDED Matters to be decided include approval by the New York State Department of Environmental Conservation and the Suffolk County Legislature. Rev. 1.1,9/97 14 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" II. Description of the Proposed Action A. PROJECT PURPOSE, NEED AND BENEFITS; SOCIAL AND ECONOMIC CONSIDERATIONS 1. Background and History. The Suffolk County Water Authority is a self-supporting public benefit corporation operating pursuant to Article 5 Title 4 of the Public Authorities Law. SCWA was formed with a two-fold purpose: the first was to acquire,construct,maintain and operate a public water supply for Suffolk County, and the second was to develop a single integrated public water supply and distribution system to serve all of Suffolk County. SCWA is without taxing power and the only revenue it receives is that obtained from the sale of water to its customers. Since SCWA is a non-profit entity, all revenue received must be used for operating expenses and for paying outstanding debts. Any excess revenues must be used for construction purposes. SCWA is the largest water purveyor in the nation using solely groundwater as its resource. SCWA currently serves a population of approximately 1.2 million which includes 335,204 customers. Its facilities include 4,789 miles of water main, 29,595 fire hydrants, 436 public water supply wells (403 of which are active) operating from 193 pumping plants, and 61 water storage facilities with a capacity of 61,930,000 gallons of water. In addition, SCWA has its own state of the art New York State Certified Laboratory which analyzes over 50,000 water samples per year. The average SCWA customer's annual water rate and usage are $238.00 and 154,000 gallons, respectively. The SCWA system is interconnected all across the western portion of the county, but water tends to be pumped and used within the same general area. Thus, customers do not receive water from just a single well but rather a water supply from several well fields in the same localized zone. In the eastern portion of the county,the SCWA system is largely interconnected but often includes discrete areas that are not interconnected with the larger system. Usually, only a portion of SCWA wells are in operation at any one time. Wells are turned on and off as the water demand fluctuates. During the winter months, only about 50% of its wells are needed. The rest of its well capacity is needed during the summer when water demand soars. Major water transmission mains are usually 12 to 24 inches in diameter. These large mains are the backbone of the system. As water is brought into a residential community, the main size gradually decreases so that most individual homes tap into mains only about 6 inches in size. Rev. 1.1,9/97 15 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" The Suffolk County Comprehensive Water Resources Management Plan which was completed in January 1987 recommends the incorporation of small community and non-community water systems into larger,more reliable public systems. The Management Plan stated that primary consideration should be given to: (1)acquisition of the North Shore Water Company by SCWA,(2) acquisition of Swan Lake and Sun Hill Companies by SCWA, (3) acquisition of the Captain Kidd Water Company by SCWA or Town of Southold,(4)acquisition of the Greenport Water District and (5)investigation by the SCDHS or SCWA of the feasibility of creating an integrated water supply for all Fire Island communities. Since those recommendations were made, SCWA has acquired the North Shore Water Company,the Swan Lake and Sun Hill Companies and the Captain Kidd Water Company. SCWA has made acquisitions on Fire Island of the water systems of Davis Park, Cherry Grove,Fire Island Pines, Summer Club, Point O'Woods,Kismet, and Lonleyville. Acquisition of the Greenport system would complete the recommended acquisitions identified in the Comprehensive Water Resources Management Plan. The Village of Greenport first became a supplier of a public water supply with its acquisition of the Greenport Water Company in 1898. Greenport expanded the service area of this system over the ensuing years to cover areas beyond the geographic boundaries of the village. In 1957,the New York State Department of Conservation Water Power and Control Commission granted approval for lY Greenport to acquire the complete waterworks distribution system of the North Fork Water Company located in the Town of Southold outside the village including the company's sources of water supply. Subsequent to this acquisition, the purported franchise area of the Greenport water system (hereinafter also referred to as "Greenport service area" or"service area") encompassed an area of approximately 15 square miles. This service area currently includes 0.9 square miles located within the village boundaries and two areas outside the village boundaries, one of 4 square miles between East Marion and Hashamomuck Pond and one of 10 square miles extending from Hashamomuck Pond west to Peconic Lane. The area to the west of Hashamomuck Pond is referred to as the West service area,and the areas to the east of Hashamomuck Pond are referred to as the East service area. (See Appendix B for map depicting the current Greenport service area.) The major unserved areas within Greenport's service area are Great Hog Neck,Peconic and the area north and west of the Hamlet of Southold. SCWA operates public water supply facilities in a small discrete area within Greenport's service area on Great Hog Neck known as "Angel Shores. Development in the remainder of the unserved areas utilizes private drinking water wells. The unserved areas represent approximately one third of Greenport's purported franchise area. The history of land use and the hydrogeology within Greenport's service area can make it difficult to provide a public water supply of adequate quantity and quality to meet existing demand. A long history of farming throughout the service area has made the wells subject to nitrate,pesticide Rev. 1.1,9/97 16 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" and herbicide contamination. The hydrogeology of the Greenport franchise area presents a problem of salt water intrusion and upconing which can make water at wells unpotable in the short term and threatens the aquifer system in the long term. The Greenport water supply has been affected by poor water quality for many decades. Because of these problems the Suffolk County Comprehensive Water Resources Management Plan categorized Greenport as a marginal water system. During certain periods of time in recent years, Greenport has relied almost exclusively on pumping from the West service area to provide water for both service areas because of contamination problems,such as nitrates,Dacthal,Temik and salt water encroachment, at the wells in the East service area. There is concern that relying exclusively on the West service area to supply water to the East service area could lead to water usage that exceeds the permissive sustained yield of the aquifer in the West service area and cause salt water intrusion and/or regional upconing. The recent approval for the expansion of Greenport's sewage treatment plant could also contribute to this condition, if not carefully monitored,by increasing the consumptive use of water in the area. A portion of Greenport's service area and one of its plants, Plant 7, is located within the boundaries of the Southold Special Groundwater Protection Area(SGPA). Two relatively new water plants,Plants 12 and 15, are located at Kennys Road just east of the SGPA boundary. The 1996 Annual Water Quality Statement for the Incorporated Village of Greenport (Appendix C) states that no health standards have been exceeded by the system and that the water supplied by the village has been of excellent quality. The system has been impacted in the past by problems with high nitrate levels, contamination by pesticides and herbicides and high chloride levels due to salt water intrusion. These problems could arise again if the system is not properly managed or adequate financial resources are not provided to maintain treatment systems utilized to make water potable. 2. Objectives of the Project Sponsor. The objectives of the project are to provide of a safe and adequate water supply at reasonable rates to customers located outside the Village of Greenport and currently served by the Greenport water system without negatively impacting the aquifer system of the region. 3. Benefits of the Proposed Action. SCWA's significant additional financial resources,its experienced and professional staff, its state of the art drinking water laboratory and its SCADA system are likely to facilitate the proper management and operation of the facilities acquired from Greenport.

Social and Economic Considerations. The current water rates for the Greenport water customers located outside the village are given in Table 2.1,below. Table 2.1 - Greenport Water Rates Greenport Residential Quarterly Rates 0 to 6,000 gallons $43.75 fixed 7,000 to 18,000 gallons $2.62 per thousand gallons 18,000 plus gallons $3.82 per thousand gallons Greenport Commercial Monthly Rates 0 to 9,000 gallons $35.00 fixed 10,000 to 60,000 gallons $2.62 per thousand gallons 61,000 plus gallons $3.82 per thousand gallons The water rates for water customers located outside the village upon acquisition of the Greenport system by SCWA are given in Table 2.2,below. Table 2.2 - SCWA Water Rates SCWA Residential Quarterly Rates 0 to 10,000 gallons $37.93 fixed 11,000 plus $2.50 per thousand gallons SCWA Commercial Monthly Rates 0 to 10,000 gallons $29.31 fixed 11,000 gallons $2.50 per thousand gallons The SCWA rate structure will provide rate reduction for all customers outside the village. There will be a minimum rate reduction of 14% for residential customers and a minimum rate Rev. 1.1,9/97 18 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" reduction of 9%for commercial customers. The average residential customer, assuming an annual consumption of 56,000 gallons,will realize a 25%rate reduction.The Village of Greenport will have the option of purchasing water from SCWA at a wholesale rate of$0.802 per thousand gallons,a rate which will be held for 10 years. B. LOCATION 1. Geographic Boundaries of Project. The current Greenport service area extends from Peconic Lane in Peconic on the west to Shipyard Lane on the east and from Long Island Sound on the north to Peconic Bay on the South. (See Appendix B for map depicting the current Greenport service area.) The facilities to be acquired are all those located outside the village boundaries, except for Plant 5, and as more accurately described in paragraph 2(a) of the contract of sale(Appendix A). C. DESIGN AND LAYOUT 1. Total Site Area. The Greenport service area currently encompasses an area of approximately 15 square miles. This service area currently includes 0.9 square miles located within the village boundaries and two areas outside the village boundaries,one of 4 square miles between East Marion and Hashamomuck Pond and one of 10 square miles extending from Hashamomuck Pond west to Peconic Lane. (See Appendix B for map depicting the current Greenport service area.) 2. Structures. The storage facilities which are part of the current Greenport system consist of a 300,000 gallon elevated steel tank and two 15,000 gallon hydro pneumatic tanks. The two hydropneumatic tanks and are not being purchased by SCWA. The 300,000 gallon elevated tank is on the west side of Moore's Lane north of Route 25 in the Village of Greenport boundaries. SCWA is purchasing this tank and leasing the site for the tank for 50 years. D. CONSTRUCTION AND OPERATION 1. Duration of Construction. There is no significant construction associated with this acquisition. Rev. 1.1,9/97 19 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" 2. Operation. The Greenport water plants acquired by SCWA will be incorporated into SCWA's supervisory control and data acquisition (SCADA) system. Adequate and capable personnel will operate the system from SCWA's Western Regional Office. The plants will be operated on a pumping schedule whereby no single well will be run continuously for extended periods of time. The goal will be to have a wide distribution of active pumping sites by having only one well at a particular site operating at a time. Laboratory analysis of water quality samples will occur at regularly scheduled intervals at SCWA's drinking water laboratory. E. JURISDICTION AND APPROVALS 1. New York State Department of Environmental Conservation. A water supply permit from the Department of Environmental Conservation for the proposed acquisition of the water supply facilities referenced above is required. 2. New York State Department of Health. This project is listed for funding under the Drinking Water State Revolving Fund(DWSRF) on the Intended Use Plan(IUP) for the bonding pool of 2/98. 3. County of Suffolk. Approval of the Suffolk County Legislature is required. 4. Village of Greenport. Approval of the Board of Trustees of the Incorporated Village of Greenport is required. III. Evaluation of the Importance of Potential Impacts A. POTENTIAL IMPACTS ON WATER Impacts on water that have been identified as being potentially significant are present whether or not the Greenport facilities are acquired by SCWA if they are not properly managed. The impacts identified in Part lI include water supply from wells greater than 45 gallons per minute (gpm) pumping capacity,the use of water in excess of 20,000 gallons per day and a potential to adversely Rev. 1.1,9/97 20 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" affect groundwater if the resource is not properly managed. In order to adequately supply public water to the Greenport area,wells with greater than 45 gpm capacity and water usage greater than 20,000 gallons per day is required. Currently,wells with capacities as high as 500 gpm are used in order to supply an average of 930,000 gallons per day. Below is a discussion of current conditions and the potential impacts to groundwater if the Greenport system is not properly managed. When compared to existing conditions,the impact of the SCWA acquisition upon water will not be significant or adverse, and it will likely result in some positive impacts to the water resources. 1. Geology. In general, the geologic formations of Suffolk County consist of thick deposits of unconsolidated,water-bearing sediments resting upon a relatively impermeable, crystalline bedrock surface. The areal extent and thickness of the various geologic units near Greenport are depicted in Figure 3-1. (Suffolk County Comprehensive Water Resources Management Plan, reprinted from U.S.Geological Survey,Atlas HA-501 -Hydro geology of Suffolk County,Long Island,New York) Figure 3-1 A4 z El N00 g a0 Mi -._ .100 I 1 r �� 111 a1 r Y r al 0 0 I _lam Upper glacial aquifer _100 I � I ' r11 i00 ..L00 wpt"aquifer 41 41 v gargta® CIAT 7 -1000 -1000 L 14 L -1100 Lloyd aquifer -1200 -1600 204fack -law -16-A -160 -100 _Ig00 rme: Vertical exaggeraricn about x 20.

Hydrology. The fresh-water lens beneath Greenport is recharged by the infiltration of precipitation. McNew-Cartright (1996) has compiled rainfall totals during the recharge period of October 15 through May 15 and the non-recharge period in Greenport for the years 1959 to 1991. The following discussion is taken from this report: Fresh ground water on the North Fork consists of precipitation that infiltrates into the soil to recharge the upper glacial(water table)aquifer. The amount of water that recharges the water table fluctuates from year to year and is determined by the type, intensity, and frequency of rainfall, by the composition, extent, and moisture content of the soils; by the type and amount of vegetation and land surface; and by the air temperature. Previous studies on Long Island have indicated that 50 percent of rainfall infiltrates to become ground-water recharge(Peterson, 1987;Miller and Frederick 1969). Studies by the Cornell University Experiment Station (located west of the study area)have refined this estimate and indicate that 75 to 90 percent of the rainfall between October 15 and May 15 becomes recharge(Steenhuis and others, 1985) and rainfall at other times of the year evaporates or is taken up by plants and does not generally reach the water table. Based upon the above,Leggette,Brashears&Graham(hereinafter also referred to as "LBG") created a table(Table 1 of Appendix D)that provides estimated recharge rates(inches per year) for the Greenport area(based on McNew-Cartwright, 1996). Under severe drought conditions,recharge is estimated to be about 10 inches per year or about 475,000 gpd/mil (gallons per day per square mile). During dry years, a recharge rate of about 16 inches or 760,000 gpd/mil can be expected. Much higher recharge rates can be expected during years of normal or above-average precipitation (20 inches or more per year). According to LBG,because the amount of fresh water in storage under Greenport is relatively small, water resource planning should consider dry and drought conditions when predicting water availability. This is because serious saltwater intrusion could occur if substantial amounts of water were to be withdrawn from storage beneath Greenport during drought conditions. 3. Hydrogeology. Rev. 1.1,9/97 22 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER 1 STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1"T' a. Introduction. The North Fork of Long Island, as with most coastal groundwater resources, functions hydrogeologically like an elongated oceanic island with a series of fresh water lenses floating on a large body of underlying salt water and separated laterally by salty zones between the lenses at major estuarine creeks. Appendix E provides a cross-sectional view of this hydrogeology. The history of land use and the hydrogeology within Greenport's service area can make it difficult to provide a public water supply of adequate quantity and quality to meet existing demand. A long history of farming throughout the service area has made the wells subject to nitrate,pesticide and herbicide contamination. The hydrogeology of the area presents a two-fold problem. First,the aquifer system on the North Fork of Long Island is surrounded by and completely underlain with salt water. Over pumping of water can cause salt water intrusion and upconing making water at the well unpotable in the short tern and threatening the aquifer system in the long term. Second, Hashamomuck Pond divides Greenport's service area into two geographic areas which are separated laterally by a salty zone. They are referred to herein,as the West service area and the East service area. Because the Greenport service area is surrounded by and completely underlain with saltwater, the Glacial aquifer is the only freshwater aquifer available for use. Generally, this aquifer contains a lens of fresh water located above a clay layer with an average depth on the order of 100 feet below grade. The limited depth of the aquifer causes a financial impact on water production operations. This is because the maximum pumping capacity of a well is limited to about 500 gallons per minute (gpm)before upconing of salt water and induced migration of nitrate plumes could occur. In many areas of the aquifer,the maximum practical pumping capacity is closer to 200 gpm. By comparison, the typical SCWA public supply well has a capacity ranging from 1,000 to 1,400 gpm and can run for extended periods without any impact on water quality or the viability of the aquifer. b. Permissive Sustained Yield and Consumptive Use Two important concepts that must be considered in supplying water in the Greenport service area are the "consumptive use"of water and the"permissive sustained yield"of the available aquifer segments. Consumptive use is the amount of water withdrawn from the aquifer and not subsequently recharged to the aquifer because of evaporation, transpiration, surface water run off and the like. Permissive sustained yield is the amount of water that may be withdrawn from an aquifer segment and consumptively used without causing adverse impacts on the groundwater or ecological resources. Adverse impacts may include salt water intrusion or upconing. Rev. 1.1,9/97 23 Full Environmental Assessment Form-Acquisition of Greenport Water System ( "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,IM" There have been a number of studies conducted regarding these hydrogeologic parameters in the North Fork of Long Island. The Comprehensive Public Water Supply Study for Suffolk County (CPWS-24) estimates of permissive safe yields began with area-specific recharge rates, made reductions for near-coast areas outside the main water budget area and made further reductions based on an'optimum"position of the salt water interface,including considerations of drought. The CPWS-24 report also defined"average net yields,"which were based on average year recharge rates. These figures are provided below in Table 3.1 Table 3.1 -Permissive Sustained Yields for Southold Town from CPWS-24 Permissive PSY per mP Average Sustained of water Net Yield Yield(PSY) budget area (ANY) (mgd) (mgd/miz) (mgd) West of Mattituck Creek 2 0.40 3.4 Mattituck Creek to Hashamomuck Pond 5.5 0.35 10.4 (/ Hashamomuck Pond to Orient Harbor 1 0.25 2.1 East of Orient Harbor 0.5 0.25 1.1 Total 1 9 - 17 Another significant report is the North Fork Water Supply Plan(NFWSP) (1983),prepared by ERM-Northeast and Camp, Dresser&McKee. The NFWSP also looked at permissive sustained yield on the North Fork and compared them to estimated consumptive water use in 1980. These figures are provided below in Table 3.2.

A 1992 Velzy study estimated permissive sustained yield for dry, average and wet years for the Greenport service area. Since the Greenport service area is divided into two geographic areas with separate and distinct permissive sustained yields, the report provided figures for the West service area and the East service area. The figures as presented in the study are presented in Table 3.3, below. Table 3.3 - Greenport Service Area Permissive Sustained Yields from Velzy _T Dry Year Average Year Wet Year West Service Area 1.08 mgd 1.67 mgd 2.34 mgd East Service Area .58 mgd 0.89 mgd 1:25 mgd Total 1.66 mgd 2.56 mgd 3.59 mgd c. Greenport Water Quantity and Consumptive Use. Hydrogeology and water quality have had a significant influence on how Greenport has obtained a sufficient quantity of water to operate its system. Since 1990 there has been a trend toward exclusive reliance on wells pumping from the West service area to provide water for both service areas because of contamination problems at the wells in the East service area. Relying exclusively on the West service area to supply water to the East service area could cause the permissive sustained yield of the aquifer in the West service area to be exceeded increasing the risk of saltwater intrusion and/or regional upconing. The recent approval for the expansion of Greenport's sewage treatment plant could contribute to this condition by increasing the consumptive use of water in the area. Appendix F contains the distribution of water pumpage by well for the Greenport system on a monthly basis since 1990,together with a summary of yearly pumpage by service area,the percent Rev. 1.1,9/97 25 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1""' pumpage by service area and total pumpage. Consumptive use attributable to public water supply for the years 1990 through 1996 is also given in Appendix F. Consumptive figures assume that all water that enters the distribution system is consumptively used. This is a conservative assumption considering the fact that all of the Greenport system is not sewered,and some of the water that enters the distribution system is recharged. This is especially true in the West service area where there is no sewer system. The average consumptive use attributable to public water for this period is.876 mgd with the high year being 1994 with.971 mgd,but there is a trend toward an increase in the consumptive use for the period. The manner in which the Greenport system is currently operated gives rise to a potential problem given the fact that the vast majority of the water pumped is coming from the West service area.When the estimated consumptive use attributable to irrigation for the West service area of.13 mgd is added to the consumptive use of.931, the high year for the West service area, total consumptive use of 1.061 mgd results. This is very near the calculated permissive sustained yield of 1.08 mgd for the West service area aquifer segment as calculated by Velzy. However under the current regime, the East service area aquifer segment has a dry year permissive sustained yield of 0.58 mgd, and only about one fifth of this yield is being utilized. Greenport has not fully utilized this aquifer segment in recent years due to contamination and other problems with the wells in the East service area. In accordance with a 1996 study prepared by LBG(Appendix D),the water needs of the Incorporated Village of Greenport could be met within the village boundaries provided an interconnection with an outside system was established to handle fires, lost well capacity or other operational problems. d. Greenport System Water Quality. Historically,high chloride levels resulting from movement of saltwater above the area wide clay layer was one of the earliest water quality problems that faced the Greenport system. High chloride levels have occurred at Plant 3 (which is not being purchased by SCWA)and in Wells 6-3, 4-8 and 8-1. These experiences lead to the construction of a number of monitoring wells in the vicinity of these water plants. The goal was to determine if the problem was related to horizontal movement of a saltwater wedge or if a layer of saltwater existed above the clay layer and was being drawn vertically upward into the wells. Sampling indicated that the chloride problem arose from vertical upconing and that the maximum pumping capacity in some areas of the aquifer was limited. The NYS DEC has required that continuous conductivity monitors be installed on all wells during recent years. Chloride problems have decreased since additional well capacity has been placed in service at Plants 12 and 15. Rev. 1.1,9/97 26 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997-- The second significant factor affecting the ability to provide potable drinking water in the Greenport service area is nitrate contamination. The following description of historical nitrate contamination associated with the Greenport system was contained in "Incorporated Village of Greenport Study of the Potable Water System Five Year Projection of Needs,"H2M Group,February 1994: The excessive use of fertilizers for agriculture has impacted virtually the entire North Fork Data from East Marion to Cutchogue have revealed sporadic nitrate concentrations well above the limit of 10 mg/l. The experience at Village wells [sic]fields has been that new wells have low levels of nitrates. Generally, these new wells are pumped very heavily due to the poorer quality at older well fields. This heavy pumpage induces movement of high nitrate concentration water toward the well f eld. Upconing of deeper higher nitrate water also seems to be occurring. Several examples of this problem have been observed to occur. During the late 1970's Plant 6 was the new, good quality plant. It was used for more than 50% of the total water supply for several years until nitrate and pesticide levels rose. During the early 1980's,Plant 8 was run very hard until quality deteriorated. The late 1980's saw Wells 6-1 and 7-1 heavily used. In 1990, Well 7-2 was made operational. This allowed greater ability to rotate the other wells, but the heaviest pumpage was focused at Plants 6, 7 and 8. Well 7-2 nitrate levels began to rise during 1991 and 1992 and now frequently approach the limit of 10 m911- 71e monitoring well data at Plants 7, 12 and 15 have allowed a better resolution of the vertical stratification of the nitrate plumes. This data indicated a strong vertical stratification of nitrates. Generally, the highest nitrate water occurs in the deeper portion of the aquifer. This is believed to be due to intensive use of fertilizers for agriculture during the 1960's and earlier. The age of the water increases with the depth at which it is found within the aquifer. The vertical profile of concentrations can yield a history of fertilizer usage at each site. Nitrate levels generally exceed the limit of 10 mg/7 at Plants Rev. 1.1,9/97 27 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" 4, 6 and 8. The levels at Plant 7 fluctuate, but require careful monitoring and balance of pumping. Levels at Plants 9, 12 and 15 should be monitored to give early warning of any long term increases of contaminant levels. The 1996 Annual Water Quality Statement(Appendix C)for the Village of Greenport system gives the maximum and average levels for each operating well before treatment. These results are provided in Table 3.8. Table 3.8 - Nitrates in Greenport Operating Wells 1996 Well No. Maximum Result(mg/1) Average Result(mg/1) 3 0.7 0.7 4-6 15.2* 14.4* 4-7 15.7* 10.3* 4-8 9.0 8.4 64 12.6* 11.8* 6-3 9.5 8.2 7-1 8.4 7.9 7-2 8.1 7.5 8 14.1* 13.1* 9 2.7 2.1 12-1 4.0 3.9 15-1 7.3 6.7 *Exceeds New York State Maximum Contaminant Level for Potable Water Before Treatment The Greenport Annual Water Quality Statement states that the water from Plant No.6,which has experienced high levels of nitrates in the past,is treated and closely monitored,with results being below the New York State Maximum Contaminant Level after treatment. Nitrate levels in the Rev. 1.1,9/97 28 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,I"T. Greenport distribution system in 1996 had a maximum detection level of 7.7 mg/1 and an average of 6.4 mg/l. The third significant factor affecting the ability to provide potable drinking water in the Greenport service area is pesticide and herbicide contamination. The pesticide Temik and the herbicide Dacthal and their respective metabolites are the principle contaminants that have impacted wells in the Greenport system. These contaminants have impacted the wells at Plants 4, 6, 7, 8 and 9. If not impacted by other contaminants such as nitrate or saltwater,these pesticides and herbicides can be economically treated with granular activated carbon(GAC) filters. The 1996 Annual Water Supply Statement for Greenport indicates that Wells 6-1, 6-3, 7-1 and 7-2 utilize GAC filters. In order to meet existing pumping demands without inducing further contamination of the available wells,Greenport has instituted a pumping schedule whereby no single well should be run continuously for extended periods. The goal is to have a wide distribution of active pumping sites by having only one well at a particular site operating at one time. There are two modes of operation for the wells: automatic operation,whereby a well cycles on and off based on the water level in the elevated storage tank,and manually. Pumpage demands are such that most of the active wells within the system will run on any given day. The wells at plants 4 and 8 have been used primarily for peak days rather than "base load"pumping due to less stable water quality at these wells. Wells 6 and 7 have historically been used extremely heavy during the summer months, but Wells 12 and 15 have recently served this purpose. The work load on the system operator has been very heavy,particularly during the summer season. This has contributed to past incidents when wells were run continuously for many days. The failure to rotate the pumping schedule of wells adequately is a major factor contributing to the migration of contaminants into the viable segments of the aquifer systems. e. Suffolk County Water Authority Operation. The SCWA will bring significant experience and resources to the fold in its operation of the facilities acquired from Greenport. SCWA has over $90 million in annual revenues, 45 years experience in operating public water supply systems on Long Island, almost 600 employees experienced in serving 1.2 million people and in operating a water plant with 4,789 miles of water main, 29,595 fire hydrants, 436 public supply wells, 61 water storage facilities with a capacity of 61,930,000 gallons of water and the largest groundwater sampling laboratory on the East Coast. SCWA's financial resources enable it to respond quickly to system problems,such as the loss of a well, without significant impacts to the rate structure because capital expenditures for such Rev. 1.1,9/97 29 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" events are distributed to its entire customer base. Its employees are experienced in dealing with such localized water quality problems as salt water intrusion and pesticide,herbicide and other types of contamination. SCWA does not have the franchise limitations of the current Greenport system and, if needed, can address the requirements of a public water supply for the area on a more regional basis than the current Greenport system can. SCWA owns property at Rocky Point Road in East Marion, which is just to the east of the Greenport service area, and at Mill Road in Peconic,which is just to the west of the current Greenport service area. The pumping sites acquired from Greenport will be incorporated into the SCWA's supervisory control and data acquisition (SCADA) system to facilitate the rotational pumping schedule. An adequate amount of personnel will be assigned to ensuring the plants are operating properly, and monitoring of the water quality will be facilitated through analyses in SCWA's state of the art drinking water testing laboratory. Applying these management and operational resources to the acquired facilities will enable a better distribution of the pumping schedule that is in accordance with up to date and accurate water quality parameters. SCWA will obtain control over Well 9 as part of the acquisition. (See paragraph 4(b) of �- Contract in Appendix A.) This well had been subject to certain legal disputes that have inhibited its full utilization in the past. This will allow a greater utilization of this East service area aquifer segment and reduce the current demand being placed on the aquifer segment to the west of Hashamomuck Pond. SCWA's significant additional financial resources, its experienced and professional staff, its state of the art drinking water laboratory and its SCADA system are likely to facilitate the proper management and operation of the acquired facilities. Thus,the potential impacts to groundwater that could occur if the system is not properly managed are likely to be reduced through SCWA's acquisition of these facilities. B. POTENTIAL IMPACTS ON GROWTH AND CHARACTER OF COMMUNITY OR NEIGHBORHOOD Impacts on growth and character of community or neighborhood has been identified as being potentially significant because the availability of public water may make residential or other development attractive. There is a host of factors that impact the potential for certain properties within the current Greenport service area to be developed, the availability of an adequate supply of water can be an important one. From a technological perspective,most sources of water can be made Rev. 1.1,9/97 30 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" potable with adequate systems for treatment. However,what may be possible from a technological perspective may not be feasible from an economic perspective so development projects usually make arrangements to have water supplied from public water supply systems to reduce the cost of providing water to the project. Through the years, the Village of Greenport has made commitments to supply water to a number of proposed development projects. The following description of development commitments of the Village of Greenport appeared in "Incorporated Village of Greenport Study of the Potable Water System Five Year Projection of Needs" which was prepared by H2M Group, 1994: The growth of the Village water supply system will be constrained for the near future by the water commitments which have been given to development projects. These commitments have been given out in units based on the nominal water demand of a single family home. The SCDHS utilized certain typical flows and equipment reliabilities during the negotiations for adding well capacity during the late 1980's. The adopted peak day flow of 0.8 GPMper service is equivalent to 1152 gallons per day per service. r This number is conservative in comparison to the values found in Table 2. The requirements for mechanical redundancy were expressed by the SCDHS as a reliability factor to be imposed on the nominal capacity of new wells. This reliability factor was set at 60%. The resulting well capacity required to serve each new water service is 0.8 GPM/0.60 = 1.33 GPM of nominal well capacity. Analysis of the incremental costs of adding services to the water system have been performed several times in the past. Accurate estimation of the share of the system costs is important to achieve equitable cost sharing between existing and future water users. The goal is to have no net cost impact on existing users when new services are added. These costs include not only well capacity but also those for storage and transmission of water. The incremental cost of adding water services has often been termed "key money" or "up front fees" because they were traditionally paid by the developer prior to the construction of a i Rev. 1.1,9/97 31 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997' development. The most recent calculation of key money costs was done in April 1991. . . . An initial estimate of key money costs was made in 1984 at$2170 per service and revised in 1985 to $2570 per service. these calculations did not include treatment costs or land costs. The 1991 figure of$4732 per service accounted for those costs but did not foresee the costs now being borne by the Village for Dacthal treatment for those anticipated under the groundwater disinfection rule. [Appendix G]shows a summary of projects which have been negotiated with the Village over the past decades. This list was developed based on a review of Village f les and is believed to include all outstanding commitments with a high degree of confidence. The information relating to the amount of up front fees which were agreed on and which were paid is based on the best available information, but is still under review. A detailed review of the amount of key money paid and the enforceability of the outstanding commitments should be undertaken. The 763 service connections to which the Village is potentially committed is equivalent to all of the services added to the system during the last 20 years. The Village should continue its review of these commitments to determine which of them can be formally rescinded. The demand for additional water service connections to the distribution system will arise primarily from the development projects listed in[Appendix G]. However,some additional growth from other projects can reasonably be anticipated. [Appendix HJ lists properties within the [purported]franchise area which have been approved or have applied for subdivision by the Southold Town Planning Board. The sales agreement between the Greenport and SCWA provides a list of pending applications or agreements with developers,which includes a list of deposits or key money that has been received by the village. Under the agreement the village covenants to return deposits of water customers (outside of the Incorporated Village), less any amounts due the village directly to the customers. Rev. 1.1,9/97 32 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" SCWA is implementing a similar key money policy to protect groundwater resources in certain environmentally sensitive areas,including the entire Town of Southold. A study conducted by SCWA found that public water supply infrastructure and distribution is more expensive in these areas due to the limitations of fresh water supplies, costs relating to treatment facilities,the need to provide backup water sources and maintain pressure for fire protection which requires more per capita for transmission mains, booster stations and other support facilities and other similar conditions. Due to these costs, SCWA adopted a policy where a key money fee of$3,000.00 would be charged for each basic service connection adjusted proportionately higher for larger services on or after February 25, 1997. This fee is similar in amount to the fees currently charged by Greenport for new service connections to their system. With the institution of this SCWA fee there will be no significantly greater financial incentive to develop property within the current Greenport service area than there is under the current Greenport fee. C. POTENTIAL IMPACTS ON AGRICULTURAL LAND RESOURCES Impacts on agricultural land resources have been identified as being potentially significant because an availability of a public water supply may include conversion of agricultural land to residential uses. The potential for these types of impacts are discussed under section B above. SEQR calls for an analysis of the impacts of public acquisitions of land or interests in land or funding for non-farm development on lands used in agricultural production and unique and irreplaceable agricultural lands within agricultural districts pursuant to subdivision(4)of section 305 of article 25-AA of the Agriculture and Markets Law. A significant number of parcels in the Town of Southold constitute an agricultural district under the Agriculture and Markets Law. SCWA is purchasing parcels 1000-30-2-100; 1000-35-1-25; 1000-35-2-151; 1000-54-3-22; 1000-59-3-16.6, 24, and 1000-69-3-4, and none of these parcels is part of the agricultural district in Southold. D. POTENTIAL IMPACTS ON CRITICAL ENVIRONMENTAL AREAS Impacts on critical environmental areas that have been identified as being potentially significant, albeit the fact that they are present whether or not the acquisition occurs, include the location of a portion of the system and acquired facilities in the Southold Special Groundwater Protection Area(SGPA),a potential to reduce the quantity of the SGPA groundwater, a potential to reduce the quality of the SGPA groundwater, and a potential to impact the use, function or enjoyment of the SGPA groundwater. The Peconic Bay System has also been identified as a series of critical environmental areas. Rev. 1.1,9/97 33 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" 1. Southold Special Groundwater Protection Area. A portion of Greenport's service area and one of its plants, Plant 7, are located within the boundaries of the SGPA. Two relatively new water plants,Plants 12 and 15, are located at Kennys Road just east of the SGPA boundary. Environmental Conservation Law Article 55 calls for a detailed statement of the effects of any proposed action on,and its consistency with,the SGPA Plan. The SGPA Plan contains general policy considerations that are applicable to all SGPA's and recommendations specific to the Southold SGPA. The general policy considerations include: (1) a nondegradation policy, (2) a policy of maximum retention and protection of undeveloped areas, (3)the development of watershed rules and(4)the strengthening of regulations and enforcement of laws that further the aims of the SGPA. The nondegradation policy includes the use of Best Management Practices (BMP) for reducing impacts associated with residential lawn areas,commercial and golf course turf by due to the use of agricultural chemicals. The policy regarding undeveloped lands includes public acquisition of watershed land surfaces,limiting density permitted development by mandatory cluster zoning based on five acre residential zoning,providing sewage treatment facilities for multi-family units or condominium developments and limiting new industrial and non-essential commercial uses. The goals of the watershed rules policy are: (1) to establish standards that ensure the protection of groundwater quality, (2) to define the types of activities that are compatible and incompatible with areas of protection, (3) to emphasize the importance of non-point controls, (4) to define zones of management and protection around wells within or proximate to SGPA's. The Plan specifically recommends monitoring of all sanitary waste discharges of greater than 1,000 gallons per day, advocates local zoning changes to prevent groundwater contamination; it suggests that existing potential source of pollution should be allowed to continue subject to periodic review by county health department and water supplier and states that existing "wet" businesses should be connected to existing STPs with discharges outside and down gradient of SGPAs. The Plan recommends that an inventory of existing commercial industrial facilities be taken to determine if they are degrading water and that monitoring wells be installed where such a potential exists. The Plan's recommendations specific to the Southold SGPA include: (1) continuation of farmland development rights acquisition programs,(2)zoning of farmland at one dwelling units per five acres together with an incentive for the transfer of development rights to sites outside the SGPA at one dwelling unit per two acres, (3)mandatory clustering at a density of one unit per five acres, (4) limiting residential development to infilling in existing developed areas around Peconic, Rev. 1.1,9/97 34 Full Environmental Assessment Form-Acquisition of Greenport Water System "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER (� STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997" Cutchogue and just west of Southold hamlet, (5) improve irrigation practices, (6) change the type of crops to ones that reduce the need for agricultural chemicals, (7) public acquisition of the few remaining wooded sites for future use as well sites as needed. The Plan also states that in order to provide for the water supply needs of the entire Town of Southold, well sites will have to be established in the vicinity of Laurel Lake, which is part of the Central Suffolk SGPA, and in the Southold area. SCWA's acquisition of the Greenport water supply system facilities in the SGPA is consistent with both the general SGPA policy considerations and the specific recommendations for the Southold SGPA. Monitor well data at Plants 7, 12 and 15 have indicated a strong vertical stratification of nitrates. Generally, the highest nitrate water occurs in the deeper portion of the aquifer because of farming practices attributable to the 1960's and earlier. While nitrate levels at Plants 12 and 15 are low,they fluctuate at Plant 7. In the 1980's Well 7-1 was heavily used, and in 1990 Well 7-2 was made operational. Well 7-2 nitrate levels began to rise during 1991 and 1992 and now frequently approach the limit of 10 mg/l. The SGPA nondegradation policy focuses on land use activities that cause a degrading of the groundwater quality. The type of degradation that has been experienced in the quality,of water at Plant 7 is believed to be attributable to higher nitrogen levels in the deeper portions of the aquifer. -— Heavy pumping of the wells at this plant is believed to cause an upconing of this higher nitrate water. While pumping of this plant is not in conflict with the SGPA general policy of nondegradation, careful monitoring and a balance of pumping should be practiced to avoid any degradation of water quality at the plant from nitrogen upconing. The general policy of nondegradation can be maintained by SCWA subsequent to the acquisition by careful monitoring and balance of pumping at Plants 7, 12 and 15. Through careful monitoring and balance of pumping of these plants, the quantity and quality of SGPA groundwater can be maintained so that its use function and enjoyment will continue., SCWA's acquisition should not have significant impacts to the SGPA general policy regarding undeveloped lands. For a discussion of the potential impacts to agricultural land resources and growth and character of the community or neighborhood see the sections above. While SCWA does not have specific powers to institute or enforce watershed rules, the acquisition of the Greenport system facilities will prompt it to fully participate in measures for watershed protection in the Southold SGPA. 2. Peconic Bay System Critical Environmental Area. Rev. 1.1,9/97 35 Full Environmental Assessment Form-Acquisition of Greenport Water System +i "THIS PROJECT HAS BEEN APPROVED FOR FUNDING UNDER THE NEW YORK DRINKING WATER STATE REVOLVING FUND AND ALL APPROVALS MUST BE COMPLETED BY SEPTEMBER 30,1997' The proposed acquisition will not adversely impact the Critical Environmental Areas(CEAs) designated by the Town of Southold because it will occur outside of the CEAs. These CEAs include the entirety of the Peconic Bay System, 500 feet from the shoreline of the bay system, designated inlets and Fisher's Island. All of the facilities to be purchased by SCWA are physically located outside of these CEAs,and therefore will not reduce the quantity or quality of the CEAs. Safeguards of these CEAs'quantity and quality are the host of state and local regulations governing activity in the CEAs. These safeguards will be unaffected by the proposed action. E. POTENTIAL IMPACTS ON PUBLIC HEALTH - Impacts on public health and safety have been identified as being potentially significant because the acquisition will likely improve the quality and quantity of public water supply. While no new wells are being proposed as part of this action, SCWA's significant additional financial resources, its experienced and professional staff,its state of the art drinking water laboratory and its SCADA system are likely to facilitate the proper management and operation of the acquired facilities. Thus,the quantity and quality of water being produced from the current sources of supply will likely be improved resulting in positive impacts to public health.

NOW, THEREFORE, in consideration of the premises and of the mutual covenants, stipulations, and provisions herein contained, it is hereby agreed as follows: 1. Subject to and conditioned upon obtaining the consents, approvals and authorizations as hereinafter provided, the VILLAGE agrees to sell, transfer and deliver to the AUTHORITY and the AUTHORITY agrees to purchase from the VILLAGE, the entire water supply and distribution system of the VILLAGE, outside of the Village of Greenport, in the Town of Southold, including additions and extensions thereto constructed, or to be constructed, prior to the closing of title as hereinafter more particularly provided. Without limiting the foregoing, there shall be included in property sold all the VILLAGE's land, wells, pumping stations, and related equipment, water storage facilities (except that water tank site shall be leased and not'sold to the AUTHORITY), water main facilities, maps, drawings or other records, hydrants, service connections, meters, customer records, easements, right-of-way, water rights, contract rights,franchises, appurtenances, and all other properties and equipment pertaining to such water supply system that are outside of the Incorporated Village,to the extent the same are owned by the VILLAGE as they are in existence, with the exception of one parcel located on South Harbor Road, known as Plant#5,with two discontinued wells to be retained by the VILLAGE. The property sold shall include all VILLAGE land,whether or not identified in this contract, and fixtures and equipment shown on a schedule annexed hereto as Exhibit 1, however, shall not include, office equipment, bank accounts, bonds, stocks or similar securities, on the corporate books of the VILLAGE. The VILLAGE shall transfer or cause to be transferred, all information regarding customer accounts (ledger sheets), and all service cards (information regarding each service). 2. (a) The VILLAGE represents that its water supply system outside Village boundaries to date consists of approximately 41 miles of water main ranging in size from 4-Inch to 12-inch diameter. There are 346 fire hydrants and a total of 2,080 customers outside the Village boundary. There are 7 water plants with 2 14 potentially active wells (see Table 1). The system includes one 300,000 gallon steel elevated storage tank. The appropriate mechanical capacity of all the wells is 3,800 gallons per minute. It also includes a portable standby generator that is used to provide backup power to certain wellfields. Annexed hereto, and made a part hereof and marked Exhibit 2, are maps showing the existing water supply system of the VILLAGE, located outside of the Village, indicating the diameter of the existing water mains shown thereon. There are certain streets that lie partly within the boundary of the Incorporated Village and partly outside of the boundary. In an effort to ensure orderly operations, one entity should have responsibility for the water main located on that street. Therefore, the AUTHORITY will operate and maintain the water main located on Bridge Street and Washington Street. All of the customers who take service from that main whose property is located within the Village will be the responsibility of the VILLAGE. The water mains located under Oak Street, Maple Street, West Street and Madison Avenue that are outside the Village boundary shall be operated and maintained by the VILLAGE. All the customers who take service from these mains whose property lies outside the Village shall be the responsibility of the AUTHORITY. The water mains located on Moores Lane, the vast majority of which are located within the Village, shall be operated and maintained by the VILLAGE. All hydrants on the above mentioned water mains shall be operated and maintained by the owner of the water main. 3 The AUTHORITY will supply water meter readings, as made, for those services outside of the Village for which the VILLAGE furnishes sewer services. It is understood and agreed, however that the VILLAGE, in making any additions and extensions subsequent to the date of this contract, may, subject to the written approval of the AUTHORITY, contract for and construct such additions and extensions as may be requested by the VILLAGE by developers or proposed customers prior to the date of closing of title but all plans therefor shall be prepared by the Engineers of the VILLAGE and copies thereof shall be furnished to the AUTHORITY and shall be subject to the written approval of the AUTHORITY, which approval shall not be unreasonably withheld. Inasmuch as the AUTHORITY will be responsible for operating and maintaining the water supply and distribution system, letters of water availability for prospective customers/developers shall be issued*}by the AUTHORITY, unless the issuance of such letters is limited by a higher governmental authority. Any affordable housing project sponsored by the VILLAGE shall not be subject to any key money requirement. The VILLAGE shall furnish a list or schedule of pending applications or agreements with developers, including a list of deposits or "key money" that has been received by the VILLAGE. (b) Apparently funded by and to be expended for water supply and distribution outside the Village and within the Town of Southold, Paragraph "5" of the Water Supply and Sanitary Sewer Agreement dated March 7, 1986, between the Village of Greenport and Greenport Development Corp., provides for a 4 "Back Bone Plant Reserve Fund" to be used for construction and maintenance for the water supply system. No part of this fund shall be assigned or paid to the AUTHORITY but the VILLAGE shall hold the AUTHORITY harmless from any claim relating to such fund. c) It is the intent of this Agreement that the VILLAGE shall deliver a water and distribution system to the AUTHORITY, existing outside of the Village and within the Town of Southold, as is, and essentially in the condition, as found by prior inspection conducted jointly by the VILLAGE and AUTHORITY, prior to the signing of this document. d) The AUTHORITY agrees to employ two current employees of the VILLAGE who are familiar with the operation and maintenance of the supply and distribution system. (e) In the event that any private property or streets, either private or public, in which are situated structures of the VILLAGE now rendering water services are closed or acquired by the State of New York, or any of its agencies, or any municipal AUTHORITY, the VILLAGE will assign and set over to AUTHORITY all rights or claims for damages or loss resulting, therefor, at the time of closing. 3. The purchase price for all properties and facilities of the VILLAGE herein referred and described, shall be payable as follows: (a) $30,000., on signing of this contract by check subject to collection, the receipt of which is hereby acknowledged. (b) The sum of THREE MILLION ($3,000,000.00) DOLLARS, less deposit, plus an additional FIVE HUNDRED THOUSAND ($500,000.00) DOLLARS for the tank 5 (located on a site to be leased to the AUTHORITY), payable on closing and delivery of the title documents. (c) The tank site shall be the subject of a lease for a term of fifty (50) years at a yearly rental of ONE ($1.00) DOLLAR. The normal maintenance of the tank will be accomplished by the AUTHORITY, however, major improvements or replacement shall be subject to the VILLAGE's approval which will not be unreasonably denied. (d) The VILLAGE shall retain the right to paint "Greenport" on the tank, at its expense. The VILLAGE shall continue to receive the entire antenna rent for existing leases. Revenues for any and all new or additional antennas, including renewal of existing leases, after reimbursement of attendant costs, shall be shared equally by the VILLAGE and the AUTHORITY. The VILLAGE shall provide the AUTHORITY with a list of all existing leases and their termination dates. (e) All existing debt of the VILLAGE Water Fund shall continue to be solely a VILLAGE liability and no part thereof assumed by the AUTHORITY. f) Carbon filters owned by the VILLAGE shall be transferred to the AUTHORITY. For those filters owned by Rhone Polenc, the AUTHORITY shall contract for its continued use. 4. Village Sewer System: a) The VILLAGE shall permit the AUTHORITY to dispose of saline removed from the water system into the VILLAGE sewer system for as long as the 6 AUTHORITY operates and maintains the water supply and distribution system but not to exceed fifty (50) years, and at no cost to the AUTHORITY. This provision shall survive closing, and the AUTHORITY will credit the VILLAGE the sum of SIXTEEN THOUSAND SIX HUNDRED SIXTY EIGHT ($16,668.00) DOLLARS, currently owed to the AUTHORITY for the rental of the GAC filter. b) The Agreement of March 7, 1986, between the VILLAGE OF GREENPORT and GREENPORT DEVELOPMENT CORP., (BRECHNOCK), provides for both water supply and sanitary sewer services. A further Third Party Agreement to separate these two services--water supply and distribution system to the AUTHORITY and sanitary sewer system to remain with the VILLAGE shall be consummated coincident with f this Agreement. 5. Sale of Water The AUTHORITY will supply water to the VILLAGE at its grandfathered wholesale rate of $.802 per thousand gallons. This rate will remain in effect for ten (10) years. Commencing at the beginning of year eleven (11), the rate for water supplied to the VILLAGE will be the AUTHORITY's wholesale rate as established in its approved rate schedule which has been "grandfathered" for the Towns of Smithtown and Brookhaven. The VILLAGE has the right to terminate purchasing water from the AUTHORITY upon ninety (90) days notice. Monthly billings for water supplied to the VILLAGE will, at the AUTHORITY's option, be based on consumption billed by the VILLAGE to VILLAGE customers and/or by the use of master meters installed by the AUTHORITY (See Exhibit "4" annexed hereto). 7 6. (a) Annexed hereto as Exhibit 5 are descriptions of sites and maps showing the parcels of real property,- , , -Bleck- , +t# , showing the lands to be conveyed and leased (tank site) by the VILLAGE to the AUTHORITY under this Agreement. (b) Annexed hereto as Exhibit 6 is a map showing any water main easements located on private property, along with a list of said easements to be assigned to the AUTHORITY. 7. (a) The VILLAGE covenants to return deposits of water customers, (outside of the Incorporated Village), less any amounts due the VILLAGE directly to the customers. ( b) The VILLAGE shall furnish to the AUTHORITY all customer computer account records, a list of all of its debts, obligations and claims against the said VILLAGE for that portion of the water supply and distribution system outside of the Village, together with the names and addresses of all such creditors and claimants to be annexed hereto as Exhibit 3. The VILLAGE shall furnish to the AUTHORITY an affidavit as to the existence or absence of such obligations. This list of creditors and claimants, or the affidavit aforesaid, shall be delivered with the signing of this Agreement and shall be amended to be effective as of the date of closing. In particular, the VILLAGE shall certify that all indebtedness for the wellsite on SCTM#1000-59-3-24, has been satisfied and that such wellsite shall be conveyed free and clear of all indebtedness. 8 (c) It is expressly understood and agreed that excepting the terms of payment set forth in paragraph "3" herein, the AUTHORITY shall assume no other obligations or liabilities of the VILLAGE and the VILLAGE agrees to indemnify and hold the AUTHORITY free and harmless, for a period of two (2) years from the date of the delivery of the deed, from any claim for any obligation of the VILLAGE existing at the time of closing or prior thereto This provision shall survive the delivery of the deed and other closing instruments. 8. All facilities and property to be conveyed by the VILLAGE shall be so conveyed and transferred free and clear of all liens and subject to a title search. 9. Subsequent to the closing, all checks or other proceeds in payment of water bills or other charges which are assigned to the AUTHORITY and which may be received by the VILLAGE shall be turned over first to the VILLAGE and the balance to the AUTHORITY. The same shall hold true, first to the AUTHORITY and the balance to the VILLAGE, for any payments due the VILLAGE but paid to the AUTHORITY. 10. The deeds, lease or assignment of lease and bill of sale and other closing instruments shall be delivered and the purchase money paid at the office of the SUFFOLK COUNTY WATER AUTHORITY on or about 5, 1997, in the morning or when I approvals as detailed in Paragraph "13" herein are received, whichever is later. The l� VILLAGE shall upon receipt of the purchase price, plus or minus adjustmentVas herein provided, deliver to the AUTHORITY a duly executed deed, lease or assignment thereof for the tank site and bill of sale of the physical water properties hereinabove described, a duly 9 executed assignment of easement and other rights, all existing easements, instruments and other data pertaining to the water operations of said company, and shall execute and deliver any and all other instruments which Counsel to the AUTHORITY and Counsel to the Seller may reasonably deem requisite or necessary to effectuate the conveyance and transfer of the property referred to herein. There shall also be delivered the required Resolution of the VILLAGE Board of Trustees approving the sale by the VILLAGE to the AUTHORITY (Exhibit 7"). Upon closing, the AUTHORITY shall: 1. Assume operation and responsibility for the water supply and distribution system outside of the Village of Greenport, at its sole cost. 2. Retain proceeds of all water sales effected after the closing date. 11. (a) With respect to the real property to be conveyed hereunder, the VILLAGE shall give, and the AUTHORITY shall accept, a title such as any reputable title company authorized to do business in the State of New York will approve and insure, subject to applicable terms of this contract. The AUTHORITY, if request is made within three (3) days prior to the date of closing of title, agrees to provide at the closing, separate certified checks as requested, aggregating the amount of the balance of the purchase price to facilitate the satisfaction of any such liens or encumbrances. (b) If the VILLAGE shall be unable to convey title, subject to, and in accordance with this Agreement, the sole obligation to the VILLAGE shall be to refund to the AUTHORITY the down payment made hereunder and to reimburse the AUTHORITY for up to $1,000 for the cost of title examination and upon the making of such refund and 10 reimbursement, this Agreement shall wholly cease and terminate and neither party shall have any further claim against the other by reason of this Agreement, and the lien, if any, of the AUTHORITY against the premises shall wholly cease. The VILLAGE shall not be required to bring any action or proceeding or otherwise to incur any expense to render the title to the premises marketable. The AUTHORITY may, nevertheless, accept such title as the VILLAGE may be able to convey, without reduction of the purchase price or any credit or allowance against the same and without any other liability on the part of the VILLAGE. The acceptance of a bill of sale, lease and-deed by the AUTHORITY shall be deemed to be a full performance and discharge of every agreement and obligation on the part of the VILLAGE to be performed pursuant to the provisions of this Agreement, except those, if any, which are herein specifically stated to survive the delivery of the deed. ( c) The AUTHORITY agrees to notify the VILLAGE in writing, not less than thirty (30) days before the date of the delivery of the deed of any objections, which there may be, to the title to said premises, and the VILLAGE shall have a reasonable time to remove such objections. (d) If at the time set for closing, the premises shall be affected by any mortgage, lien or encumbrances, other than those subject to which the property is hereby sold, as herein provided, which may be liquidated or discharged by the payment of a sum of money, same shall not be an objection to title, but in that event, the VILLAGE shall deposit with the title company insuring the title or any neutral depository, a sum of money sufficient to cover same. 11 (e) Receipts or letters signed by the obligees, their agents or attorneys, evidencing the payment of installments of principal and interest, shall be sufficient evidence of the reduction of principal and payment of interest. (f) If, on the date of closing, there shall be conditional bills of sale of record, which were filed on a day more than three years prior to closing, this shall not be deemed to be an objection to title, provided that the VILLAGE executes and delivers to AUTHORITY, an affidavit setting forth that the property covered by such conditional bills of sale is no longer in the premises, or if such property still is in the premises, that such property has been fully paid for. (g) Unpaid liens or taxes and assessments shall not be an objection to title, but the amount thereof, plus interest and penalties thereof, if any, shall be satisfied prior to closing by proof of payment. (h) Unpaid franchise taxes of any corporation in the chain of title, shall be no objection to title, provided the VILLAGE deposits any amount required by AUTHORITY's Title Company, to be held in escrow, to secure the payment of any unpaid franchise taxes, within sixty (60) days from the date of closing of title, or provide an undertaking satisfactory to the AUTHORITY's Title Company or proof of payment of tax. (1) All sums paid hereunder on account of this Contract are made liens on the premises. 12. By this Contract, the VILLAGE shall transfer and assign to the AUTHORITY any and all claims which it may have relating to groundwater contamination of the wells which are purchased by the AUTHORITY as a part of this transaction. This assignment 12 l shall survive the closing of title herein and shall exist for as long as the AUTHORITY operates the water supply and distribution system, which is the subject of this Contract. 13. This Agreement and performance hereunder, are subject to, and conditioned upon, the following: (a) The approval of the New York State Department of Environmental Conservation and its authorization to the AUTHORITY to extend its operations to include the territory of the VILLAGE (outside the Village of Greenport). The AUTHORITY shall apply to the Department of Environmental Conservation for such approval and authorization, at its cost. (b) The approval by the Suffolk County Legislature for the purchase of the VILLAGE by the AUTHORITY. The AUTHORITY shall apply for such approval, at its cost. In the event any of the consents, approvals and authorizations hereinabove referred to (Paragraphs "13" herein), after application duly made therefore, are refused or denied, or granted on conditions not expressed or contemplated in this Agreement (unless such conditions are acceptable to the party charged therewith), then this Agreement and all the terms and provisions thereof shall be deemed canceled and the respective rights and obligations of the parties hereunder, shall cease and determine. 14. The VILLAGE specifically represents that it is duly authorized to execute this Agreement by virtue of a Resolution of its Trustees dated June 6, 1997, a copy of which is annexed hereto and called Exhibit 7 and the AUTHORITY likewise represents that it is duly authorized to execute this Agreement by virtue of a resolution of its Members on 13 June 24, 1997 and Certificatation dated August 26, 1997, a copy of which is annexed hereto and called Exhibit B. 15. The parties represent to each other that no broker brought about this sale and no person or agency will receive any commission or benefit of any kind as a result of this sate. 16. The VILLAGE has not made, and does not make, any representations as to the physical condition, income, expenses, operation or any other matter or thing affecting or relating to the aforesaid premises, except as herein specifically set forth, and the AUTHORITY hereby expressly acknowledges that no such representations have been made, and the AUTHORITY further agrees to take the premises in their present condition, having made an inspection thereof, except that it is the intention of the parties that the VILLAGE will deliver a water system in working condition, normal wear and tear excepted. 17. This Agreement may not be changed orally but only by an Agreement in writing and signed by the party against whom enforcement of any waiver, change modification or discharge is sought. 18. Any notice or demand, which under the provisions of this Agreement or otherwise may or must be given or made, shall be in writing and may be given or made by mailing the same by registered mail or certified mail to the address set forth herein before.

This statement provides basic information relative to the current status of the water quantity, quality and water conservation programs of the incorporated Village of Greenport. A summary of the 1996 laboratory testing results from the distribution system and a review of water conservation measures available to the Village's consumers are provided. The Village Water Department has continued its programs to provide water meeting all health standards and to improve aesthetic quality to those areas served by rusty water mains. All water supplied by the Village has been of excellent quality; no health standards have been exceeded. Unfortunately, public perception lags this reality by many years. Improvements to water system operational procedures have reduced problems with high nitrate levels in the ground water before treatment and have virtually eliminated the problem of high chloride levels due to salt water intrusion. Construction of additional carbon filter units has restored the available capacity of wells impacted by herbicides. An aggressive program of water main flushing, treatment with iron sequestering agents and replacement of outdated rusty water mains will continue during 1997. The source of water for the Village is groundwater from the Glacial aquifer beneath the North Fork. Generally, the water quality of many areas of the aquifer is acceptable, although there are localized areas of contamination by nitrates, pesticides and herbicides and the pH of the untreated water is relatively low (acidic). The water distributed from the Village's active wells meets all water quality criteria established by Federal and State agencies after treatment. The water from Plant No. 6, which has experienced high levels of nitrates in the past, is treated and closely monitored, with results being below the New York State Maximum Contaminant Level after treatment. The nitrate levels in the distribution system are below the drinking water maximum level, as shown by the data in this report. The approximate population (year-round residents) served by the Incorporated Village of Greenport during 1996 was 8,500. The total amount of water withdrawn from the aquifer in 1996 was 339,000,000 gallons, of which approximately 65 percent was billed directly to consumers. Approximately 20 percent of the water pumpage has been accounted for in the following ways: discharge from the distribution system due to water main breaks, use of water from hydrants for fighting fires and continuously-running water at the sampling lines at monitoring wells, which help to provide around-the-clock monitoring of water quality. Water is also run continuously for chlorination processes at the Village's municipal waste water plant. In addition, the Village Water Department has initiated a water main flushing program in order to minimize rusty water problems and improve the aesthetic quality of the water. Approximately 14 percent of the water pumpage is considered unaccountable. The Village utilizes a step billing rate schedule which varies by service size. The Village does not have taxing authority over areas which are within the water franchise but outside of the Village limits. Consequently separate step billing schedules are used for customers inside the Village boundaries and those outside. Rates for 3!4-inch residential services based on quarterly water use are given below: CONSUMPTION IN VILLAGE OUTSIDE (GALLONS) BILLING RATE BILLING RATE First 6,000 $35.00 $43.75 6,001 to 18,000 $2.10 Per $2.62 Per 1000 Gallons 1000 Gallons 18,001 and Above $3.05 Per $3.82 Per 1000 Gallons 1000 Gallons WATER QUALITY DATA During 1996, a total of 120 bacteriological samples were taken from the distribution system of the Incorporated Village of Greenport. There were no violations of the requirements of Part 5 of the Sanitary Code as it relates to microbiological water quality. The Village of Greenport provides various types of treatment at the eight plant sites throughout the water system. Each plant provides chlorination facilities for disinfection. Caustic soda (sodium hydroxide) is utilized for pH adjustment. Granular activated carbon treatment filters are located at Plant Nos. 4, 6 and 7 to remove the pesticide Aldicarb and the herbicide Dacthal. A nitrate removal system is utilized at Plant No. 6 to reduce nitrate levels in the water to below the drinking water standard. LEAD AND COPPER RULE The Village continues to conduct a special investigation of the incidence of lead and copper leaching from household plumbing and fixtures in accordance with USEPA regulations. The study consisted of 20 first draw samples. The results of the study are shown in the table below. Action Level_ -,Testing Detection Actual Tests-� Limits ,,'Limits ;" '_,;� -.;(90th Percentile) Lead 0.015* 0.001 0.0081 Copper 1.3* 0.002 0.84 *The EPA regulation specifies an action level for lead and copper levels at the 90th percentile of samples taken. Based on the testing results, the pH adjustment treatment utilized by the Village is considered to be optimal and will continue. WATER CONSERVATION In 1996, the Incorporated Village of Greenport continued to implement a water conservation program, including printing notices in local newspapers which addressed water conservation. The Village's overall pumpage for 1996 decreased by 2.5 percent as compared to 1995. The decrease can be attributed to the District's conservation measures, fewer water main breaks and reduced flushing of water mains. Residents of the Village can also implement water conservation measures such as retrofitting plumbing fixtures with flow restrictors, modifying automatic lawn sprinklers to include rain sensors, repairing leaks in the home, installing water conserving fixtures and appliances and maintaining a daily awareness of water conservation in their personal habits. Besides protecting our limited underground water supply, water conservation will produce a cost savings to the consumer in terms of both water and energy bills due to the use of hot water. The following table presents water conservation measures which are readily available to the consumer and the estimated percentage of savings in water and energy. % Water % Energy Conservation Measure Savings Savings Conscientious Use of Water 6.9 4.0 Toilet Leak Repairs 14.0 0.0 Toilet Dams 10.2 0.0 Toilet Displacement Devices 12.9 0.0 Dual Flush Toilets 19.0 0.0 Low Flow Shower Heads 13.9 7.0 Shower Flow Restrictors 11.2 5.6 Faucet Aerators 1.4 0.7 Faucet Flow Restrictors 1.4 0.7 Alter Irrigation Timing 7.0 0.0 Irrigation Sensors 12.0 0.0 Water Conserving Appliances 6.0 3.0 Below are listed the analytical testing results for 1996 for those constituents required to be tested for under Part 5 of the State Sanitary Code for distribution sample locations as well as additional monitoring voluntarily performed by the Village. Where more than one analysis per year was conducted on a specific constituent, the range of results from highest to lowest during the reporting period is listed. The applicable state guideline, standard, or maximum contaminant level (if established) for each constituent is listed.

F�nAcycAnq Ra lr►���n�T+v!`. — SUFFOLK COUNTY WATER AUTHORITY GROUND-WATER AVAILABILITY IN THE INCORPORATED VILLAGE OF GREENPORT, LONG ISLAND Introduction Suffolk County Water Authority (the "Authority") is a public benefit corporation that was created by resolution of the Suffolk County Board of Supervisors in 1937 and is operated under the Public Authorities Act of 1951. The Authority was formed with a two-fold purpose. The first was to acquire, construct, maintain and operate a public water supply for Suffolk County. The Jsecond was to develop a single integrated public water supply and distribution system to serve all of Suffolk County. In accordance with these goals, the Authority has, in recent years, been expanding its water supply and distribution network into the Town of Southold. At the present time, the Incorporated Village of Greenport water system extends from Peconic Lane in the west to East Marion (figure 1). The actual Village boundaries are shown on figure 2. In discussing the feasibility of the Authority acquiring the Greenport system, the Mayor of Greenport, Mr. David Kapell, and the Chairman of the Authority, Mr. Michael LoGrande, decided to determine if the water needs of the Incorporated Village of Greenport could be met within the Village boundaries. Subsequently, the Members of the Board of the Authority approved a resolution authorizing Leggette, Brashears & Graham, Inc. (LBG) to conduct a study of the available ground-water resources in the Village of Greenport. The study, which is the subject of this report, consisted of a site visit to the Village, an interview with Mayor Kapell and the water-system operator, Warren Jensen, a review of past reports on the hydrogeology of the area, and independent calculations. A list of the reports reviewed is included at the end of this report. Exicting Supoly Wells Within the Incorporated Villa= The Incorporated Village of Greenport acquired, in 1898, the Greenport Water Company which had been established in 1887. There were, at one time, three well fields which supplied the Village, all located on Moores Lane between North Road and Route 25 (Main Road). The -r locations of these water plants are shown on figure 3. I _ J -2- 1 There is very little information available regarding Plant No. 1 and Plant No. 2. �J Apparently, these wells were abandoned for public water-supply purposes in the 1950's because of water-quality problems. It is likely that they were over-pumped and induced upward migration of the underlying salt water. The following excerpt is from Hoffman, 1961: Station 1 has two wells about 35 feet deep that are pumped separately. Water from Well S1668 (figure 12, H-21) has had chloride concentrations ranging from 76 to 94 ppm (pans 1 per million); and Well S1669 ... showed concentrations of 135 and 153 ppm in the summers of 1949 and 1950, respectively. These chloride concentrations indicate an admixture of salty and 1 fresh water. Data obtained during the drilling of test Well S490 .... drilled 690 feet to bedrock �1 at Station I in 1903, indicated salty water at a depth of 225 feet (Veatch, 1906). These data are 1 incomplete, however, and neither the salt-water level nor the actual chloride concentration is known. During the 1940's when the existing wells at Station 1 (51668 and 51669) were pumped for brief periods at a rate of 600 gpm (gallons per minute), marked and rapid increases in the chloride concentration of the pumped water were observed (Harry Monsell, Village of Greenport Department of Public Works,personal communication). As these wells are about half a mile from any tidewater, this contamination is probably the result of upward movement of underlying salty water. In 1953, when Wells S1668 and 51669 were pumped at a rate of about 50 gpm each, they 1 produced water having a chloride concentration ranging from 76 ppm to 153 ppm. " J According to a report by the H2M Group (1994), Plant No. 1 was used for cooling water at the power plant, though Mr. Jensen says that this is no longer true. Plant No. 2 apparently Jconsisted of one dug well which has not been used in over 40 years. 1 There is considerably more information on Plant No. 3, which is still operational, though the wells are used infrequently. Background information, also from Hoffman 1961, is presented below: Station 3 of the Village of Greenport water system comprises six wells (S1673-78 ...) about 55 feet deep. These are pumped together, and the mixed water is pumped into the distribution system. Figure 13 shows the monthly variation in the chloride concentration of the water from this 7 R$ASHuAw & GRAHAM.INC. -3- station together with the monthly pumpage and monthlyprecipitation. Figure 14 shows the same data on a daily basis for October 1951. Chloride concentrations of water pumped at this station throughout a period of years have ranged from 123 to 424 ppm, the concentration being highest in the summer when withdrawals are greatest. These concentrations are substantially higher than that (45 ppm) determined in 1932 for the water pumped from Well S178 at the same site. Extensive spreading of water of lower chloride concentrations during recent years has helped somewhat in reducing the contamination (referenced figures are in the Appendix). Apparently in the past, water was diverted from Moore's Drain and was allowed to flood the area around the well field. This would not be a reliable practice in drought years. A geological log of Well No. S-178 at Plant No. 3 is presented below (Leggette, 1938): 1 Well 5-178, Village of Greenport, one of six similar wells at well field No. 3, about 31"dle north of main pumping station, Greenport. (21H, 1.7N., 2.2 W.). Altitude about 20feet above sea level. Record furnished by State Department of Health. . Description Thickness Depth (feet) (feet) Boulders and stones 16 16 Gravel, clean. with some sand 9 25 Clay 7 32 Sand and eravel, coarse 23 55 _ Screen-set from 40 to 55 feet. Static water level- 16 feet. The current status of Plant No. 3 was presented in the 1994 H2M report, as quoted below: -� Plant No. 3 is at the southwest corner of Moore's Lane and North Road and consists of three active wells (north suction field) and three inactive wells (south suction field). Well depths range from 42 to 57 feet. The capacity of this plant is about 308 gpm. For many years, when six wells were in service and pumping capacity was greater, the well field was,flooded by pumping r r............y�"1,-...._........ RS nY...... Tom,.. from the Village Reservoir during periods of heavy use in an attempt to induce recharge. This minimized the increase in chloride levels, which at times exceeded the recommended drinking water standards. Most of the site is heavily wooded which reduces net recharge to the aquifer. This plant is stall a possible location to induce treated water from another site to increase the —� available capacity and improve water quality. Water quality from this plant has deteriorated due to increasingly high concentrations of Iiron and manganese. The maximum contaminant level for each of these constituents has been exceeded since 1989. Even though these standards have been established for aesthetic reasons rather than a threat to health, this plant has been relegated to reserve status. Geologic information in this area is not complete, but from data available there are thick, tough clays south and west of Plant No. 3. Apparently these clays pinch out between the north and south suction fields. North and east there is more sandy material with clay at depths of about 60 feet. Some years ago, test borings were conducted adjacent to and south of Plant No. 3 and included a test well adjacent to the pump house. The boring indicated two possible substrata less than 60 feet deep. The test well was constructed in the south suction field to the shallower depth, but was non-productive. It is believed that additional test borings in the northerly section could — yield better results. This plant is located within the Village electric grid. Consequently, power costs at this location are about half of the LILCO rates charged at other water plants. These three well sites are the only known public water-supply sites within the Incorporated Village limits. I-Iydrogeology of Greenport For the purposes of this report, the hydrogeologic framework within which a Village water rg supply would be derived is bounded by Stirling Basin on the northeast, Chapel Lane on the —T southwest, Pipes Cove and Greenport Harbor to the southwest and Long Island Sound to the 1 T V#--vm-w. 'R"•`l••v,tiff R. 1,r•....• T%j- -5- 1 northwest The land surface elevation varies from sea level to about 50 feet above sea level, and —.1 averages about 15 feet above sea level. 'There have only been a few wells drilled below the upper glacial formation in the Town of Southold, so much of the geology is inferred. The upper glacial aquifer extends, in Greenport, — from the land surface to about 100 feet below sea level. The Magothy underlies the upper glacial to an elevation of about 480 feet below sea level, and the Raritan Clay underlies the Magothy to an elevation of about 600 feet below sea level. The sand member of the Raritan (Lloyd aquifer) probably extends from about 600 to around 700 feet below sea level (based on the log of Well S-189 drilled in Orient). Of the three major water-bearing units underlying this area (the upper glacial, Magothy aquifer and Lloyd aquifer) only the upper glacial is known to contain fresh water. In a letter to the Suffolk County Department of Health Services, Mr. Robert Holzmacher (November 7, 1995) mentioned a well drilled in 1902 into the Lloyd at Plant No. 1 and "was reported to be slightly artesian and produce fresh water". There are no records available for this well, however, a well drilled at Orient Beach State Park in 1935 encountered salt water in the Lloyd as did a well drilled in 1918 at Southampton Beach (see the attached well records). While it is possible that there is some residual fresh water within the Lloyd under Greenport, its extent is probably limited and them would be no source of fresh-water recharge. This means that any water pumped from this —�• aquifer would be mined (not replenished) and would be of finite quantity. Wells should only be _1 contemplated in this aquifer for emergency or short-term peak supply purposes. It is possible that 1 the NYSDEC would not allow withdrawals from the Lloyd. The entire study area is underlain by salt water below a relatively thin lens of fresh water. The depth of the fresh waterlsalt water interface is the primary limiting factor for individual well yields in the Village. A recent study conducted by the U.S. Geological Survey (McNees and Amu, 1995) indicates that the maximum depth of the interface is about 60 feet below sea level (about 80 feet below grade). The top of the fresh-water lens is represented by the water table, which is only a foot or two above sea level. The water-table elevation and configuration is shown i_ l -6- T on figures 4 and 5. The water,table in April 1950 was clearly being influenced by water —J withdrawals from the Greenport wells. In October 1989, the water table was about 2 feet above sea level. Assuming that the Ghyben-Herzberg relationship is valid for this area (a formula which predicts that for every foot of water-table elevation above sea level there should be a —T corresponding fresh-water lens of 40 feet below sea level) (Hoffman, 1961), it is likely that the J long-term average water-table elevation is about 1 1/2-feet above sea level. T The primary aquifer parameter used to calculate the potential yields of individual wells ,J is hydraulic conductivity. This is the amount of water which can move through a square foot of aquifer material under a hydraulic gradient of one (expressed in gallons per day per square foot or feet per day). Estimates of hydraulic conductivity of the upper glacial aquifer in Southold range from 1,500 gpd/fe (regional estimate by McClymonds and Franke, 1972) to 4,400 gpd/fe in Jamesport(based on a pumping test). A recent pumping test conducted by the Suffolk County Water Authority was run near Laurel Lake. Analysis of this test revealed a hydraulic conductivity of 2,200 gpd/fl. A value of 2,000 gpd/fe has been used in this report to calculate potential well .� yields. Ground-Water Recha= 1 The fresh-water lens beneath Greenport is replenished by the infiltration of precipitation. --1 McNew-Cartwright(1996) has compiled rainfall totals during the"recharge period" of October 15 through May 15, and the non-recharge period in Greenport for the years 1959 to 1991. The following discussion is taken from her report: Fresh ground water on the North Fork consists of precipitation that infiltrates into the soil 1 recharge the upper glacial water table) aquifer. The amount of water that recharges the water to rec ge pp g ( table,fluctuates from year to year and is determined by the type, intensity, and frequency of rainfall;by the composition, extent, and moisture content of the soils; by the type and amount of vegetation and land surface; and by the air temperature. Previous studies on Long Island have indicated that 50 percent of rainfall infiltrates to become ground-water recharge (Peterson, 1987, -7- Miller and Frederick, 1969). Studies by the Cornell University Experiment Station (located west of the study area) have refined this estimate and indicate that 75 to 90 percent of the rainfall between October 15 and May 15 becomes recharge (Steenhuis and others, 1985) and rainfall at other times of the year evaporates or is taken up by plants and does not generally reach the water table. Based on the above, LBG created table 1 which shows expected recharge values in inches. 1 Review of the table reveals that under the most severe drought conditions, recharge is about 10 inches per year, or about 475,000 gpd/mit (gallons per day per square mile). During dry years, a recharge rate of about 16 inches can be expected (about 760,000 gpd/mi'). Much higher recharge rates can be expected during years of normal or above-average precipitation (20 inches or more per year). However, because the amount of fresh water in storage under Greenport is relatively small, water resource planning should consider dry and drought conditions when -A predicting water availability. Under the main body of Suffolk County there are billions of gallons of fresh water in storage that can be drawn on to sustain supplies through a drought. However, if substantial amounts of water were to be withdrawn from storage beneath Greenport during a drought, serious salt-water intrusion could occur. The recharge area available for replenishing ground water within the influence of wells is about 0.8 square mile. Therefore, the drought recharge is about 400,000 gpd and the normal dry _ year recharge is about 600,000 gpd. The entire Incorporated Village is sewered, so there is no recharge available from septic - systems. While this factor limits future water withdrawals, it should also result in better water -� quality than if the populace relied on septic systems. —� Potential Well Yields Wells must be carefully designed and their use closely managed in Greenport to avoid the upward migration of salt water. Figure 6 illustrates salt-water upconing beneath a well. A properly designed well takes into account the acceptable "critical rise" of the salt water. 1 Schmorak and Mercado (1969) presented an equation for determining the rise of the fresh- water/salt-water interface beneath a well: where: T Z = rise of interface 2ndK(A") Pj Q = pumping rate d = distance from bottom of well screen to static interface T K = permeability PS = density of salt water p f = density of fresh water OP = (P;Pf) For z/d = 1/3 T Qnm=3 nd=K(A") t —� where: Q . is the maximum pumping rate allowable without upconing occurring above the point of rise. 1 Schmorak and Mercado state that the rise in the salt-water interface should be kept to one third of the distance between the screen bottom and the interface. However, this assumes a homogenous and isotropic aquifer. Chandler and McWhorter (1975) found that anistropy in hydraulic conductivity results in less of a rise in the interface than what would be predicted using the above equation. They show that with a horizontal to vertical conductivity ratio of 10 to 1 'P... T^. �T T.• . i 1 _ j -9- (which is the accepted ratio in the upper glacial aquifer) that the rise in the interface calculated using the above equation can be set at 50 percent of the distance between the bottom of the screen and the interface. In determining the optimum well design and pumping rates, we assigned the following •' — values to the variables in the equation: d = 30 feet (wells screened 30 feet into the saturated aquifer) K = 2,000 gpd/fe .--I A P/Pr = 1.025 l Allowing for a critical rise of one half of d (15 feet), the maximum pumping rate from a well should not exceed 100 gpm on a 24-hour per day basis. This rate would only be appropriate for locations where the interface is 60 feet below sea level, which applies to Plant No. 3 and former Plant No. 2. At locations where the interface is at 45 feet below sea level, such as at Plant No. 1, wells should only be completed to about 20 feet below the water table and be pumped at no more than 65 gpm. The preceding analysis presents individual well yields which should not be exceeded. The other factor in determining water availability is the recharge rate. As stated previously, the - drought recharge rate is about 475,000 gpd/m&. The entire recharge area which could be captured by wells is about 0.8 to 0.9 square mile resulting in a long-term safe yield of about 400,000 gpd. Water Demand Table 2 shows the water usage within the Incorporated Village Boundaries over the most —� recent 12 months. The average usage was 234,000 gpd. The peak month (assuming one third of the August residential billing and September commercial usage) was 10,700,000 gallons, or about 356,000 gpd. Therefore, on a monthly basis, the requirements of the Village can be met, even �T in a 1-in-30-year drought. I T v,-r.r-rrr. TFp4raw 4Rs `j GR4mty. INN. J -10- For purposes of water-supply planning, the peak daily usage is assumed to be twice the average daily usage, or about 710,000 gallons on a peak summer day (about 500 gpm). This demand exceeds the recharge rate, and probably would exceed the potential well capacity in the 1 i Village. 1 Wa r Q lay lity The Greenport water supply, both within and outside of the Incorporated Village boundaries, has been affected by poor water quality for many decades. High chloride content (due to overpumping), high nitrates and pesticides (from farming) and iron and manganese (naturally occurring) have all been present. With the exception of Plant No. 3, however, there is very little data on the current water quality within the Incorporated Village. Plant No. 3 has experienced chlorides as high as 117 mg/l (milligrams per liter) in recent Jyears. It is not known at what rate the well(s) were being used which resulted in this apparent salt-water upconing. In December of 1991, however, during a period of low usage, the chlorides were 40 mg/l. It is anticipated that with proper management, the chloride content can be kept to acceptable levels, though it is likely that the salt-water/fresh-water interface has been smeared due to past overpumping and that there may be a wide zone of transition. A study by the USGS (McNew-Cartwright, 1996) included installation and sampling of monitor wells in the Moore's Lane area. Chlorides in the shallow water were generally below 20 mg/1 (see the Appendix). Nitrates at Plant No. 3 have ranged from 0.7 to 3.9 mg/l in recent years. The reduction in agricultural land use and the presence of sewers will probably result in overall nitrate levels in 7 Greenport that will remain below 10 mg/1. It is likely that organic chemical concentrations will 7 also be acceptable. The presence of high iron and manganese is unavoidable and will probably require treatment. Experience in Montauk, however, has shown that increasing iron can be attributed to 1 T•rr- F1Tr.BRA-Srn-ARS & GRAHAM, INC. _1 -11- increasing salt-water intrusion. It is possible that close well-field management to minimize salt- water upconing will have a beneficial effect on iron levels. Development of a Water Supply As has been long-recognized by hydrogeologists, the best way to develop a reliable water supply in area underlain by salt water is to install multiple low-yield wells, instead of a fewer 1 number of high-yield wells. A previous section of this report provided maximum potential well yields for the Incorporated Village area. In order to safely pump the drought year recharge of 400,000 gpd (280 gpm), it would be best to spread the pumpage out to four wells. Existing Plant No. 3 could be pumped at 100 gpm, and a new well at former Plant No. 1 could be pumped at 65 gpm. A new well in the vicinity of Silver Lake could be pumped at about 80 gpm, and a new well where Moore's Drain crosses Route 25 could be pumped at 65 gpm. This is a total pumping rate of 310 gpm. The locations of these wells and the area needed to balance the yields based on the drought recharge rate are shown on figure 7. Actual test drilling, pumping tests and water-quality testing would be required to determine if this approach would be feasible. It is also unknown at this time what the combined water quality would be and, therefore, what treatment would be required. The current storage capacity is 300,000 gallons. This means that if the entire well capacity were to be used, and if the tank were full, the system might be able to meet a peak day demand. A peak weekend may be questionable. It is possible, based on site-specific testing, that additional wells could be installed and pumped judiciously for peaking purposes only. Under any scenario, the water supply should be closely monitored and managed to avoid degrading the aquifer. Additional storage capacity would be desirable, and an interconnection with the system outside T v*-r%rrmr. RgrSvc.oc R. rip#v�M Twln _ -12- of the Village boundaries would be essential for being able to handle'fires, lost well capacity or other operational problems, or other emergencies.

Leggette 551 Fifth Avenue New York, N.Y. Dear Mr. Leggette: A week or two ago Mr. Clifford Crafts, Chairman of the Greenport Rater Supply Fact Finders Committee, asked me to attend a meeting of his Committee on December 281, 1950 to explain the work of the Geological Survey in the Greenport area and to assist his Committee by pointing out the hydrologic principles involved in obtaining a continued satisfactory municipal supply of water at Greenport. I was unable to attend because of previous commitments and accordingly asked Messrs. N. J. Lusczynski and J. F. Hoffman ,M of this office to attend the meeting and assist the Fact Finders Committee. ] Mr. Lusczynski has furnished me with a memorandum giving the main points of the discussion at the meeting of the Committee. _ As the ground-water supplies in the Greenport area are none too plentiful and since a satisfactory supply for the community is a matter of considerable importance on a county-wide basis, I am sending along a copy of Mr. Lusczynski's memorandum for your inform- ation. As this memorandum has not been approved it w eldase to the _�. . public by the Director of the Geological Survey, oubap preciated if it would be treated as confidential material. Very truly yours, M. L. Brashears, Jr. District Geologist Nov York-New England Enclosure. • DATE: December 29 1950. - TO : M. L. brash ears, Jr., Hiaeola, Id.Y. (Cid) s F20H s N. J. Lusczynski, Hineola-, W.Y. (GV) SUBJECT: Greenport water-supply problem- On December 289 19509 the 25-man Fact Finders Committee, through Mr. Clifford Crafts as chairman, invited representatives of the U.S- Geological Surrey, (N. J. Lusczynski and J. F. Hoffman) and Fred Biele, private consulting engineer, to discuss the possibility of developing an adequate water supply within the franchise area of Greenport. Prior to the hearing, the subcommittee agreed that a supply of 200 zillion gaUcns by 1960 would fora the basis of the discussion. No consideration was given to possible increased demand beyond this period. It was learned that the Suffolk County hater Authority had withdrawn �:•' its offer of supplying water from its contemplated plants in Southold on December 26th. This was done mainly because of the extreme opposition exhibited by some of the citizens of Greenport with regard to the details of the Suffolk ' County Nater Authority plan- )[any other considerations were also involved apparently. At the meeting, Mr. Crafts outlined in general the details of the plan (alternate to Suffolk County Water Authority) as set up by his committee. Later, Messrs. N. J. Luscsynslci and J. F. Hoffman were first quizzed by about 20 members of the committee after hawing presented the general hydrology and 9e0106Y of .• Greenport and East Harioar as follorat Mft%enport, according to the records of Mr. H. Xonsel, Superintendent ] of the Gresnport Deparbwmt of Public Woricm, had an average precipitation of 33.17 inches during the 10-rear period from 1940-49. A range in precipitation from a low of 27 inches in 1949 to a high of 42 inches in 1942 was observed. l Precipitation at Greenport is thus recognized as decidedly below that measured in most other localities in Suffolk County and in western Long Island. At Setau et, and average -of 43 inches, 10 inches sora than in Greenport, was recorded from 1940-49. There are no underground streams or channels that conduct water from ' -Connecticut to Lon6 Island. rain•: t sloeoLt�gaIslaad. Theare he only refore, Gs rt of fresh water in Greenport g�e�� mat all can depend only on precipitation to replenish its aquifers the precipitation can be utilized for replenishing the surface stream and the underground reserves. Studies made by the New York Board of Water and transpiration. dicates that approximately 17 inches are consumed by evaporation As'a result, during average yew in Greenport and East Karion, approximately 16 inches or about half of the normal precipitation is available for recharge. This amounts to a rate of about 3/4 million gallons a day per square mile which is less than elsewhere on Loess Island. In localities where 45 inches of pre- cipitation ecipitation are measured annually about 17 inches is lost in gyapo-tranpirationg 7 inches rags off as surface flow, and 21 inches percolates to the underground aquifers, and the ground-water accretion amounts to about 1 million gallons a day per square mile, or 0.2 million gallons a day per square mile more than in ,. : ' Greenport and 31st Marione In Greenport, a small stream of unknown runoff drains only about 500 acres of land. No surface streams exist in East Marion. In spite of the much smaller loss by surface flax, the annual replenishment to the underground sources in Greenport and East Marion is less than in other parts of Long Island where higher precipitation ours. •- The total net area available to transmit part of the rain, snow, and 1 sleet to the nater table totals approximately 1-3/4 square miles (swamps and low- living areas adjacent to the shore line have been excluded) in Greenport. On the basis of a recharge rate of Oen million gallons a day per square mile the total annual recharge frog precipitation amounts to nearly 500 million gallons. A nater supply system has to meet the demand at all times especially during extended dry periods when the dnand will also be higher. If than it can 1 be accurately estimated that only one half of the normal recharge occurs under sect most adverse conditions, a sustained supply of about 250 million gallons can be depended on in the franchise area of Greenport and Est Marion. The one-half reduction my be low or high but a more accurate estimate can be obtained from a more detailed study of rainfall records in Greenport and other longer records elsewhere in Long Island. In any event the 250 million gallons, as determined approximately is slightly above the 200 million gallons set up by the Fact Finders Committee as _ a rate of pumpage not to be reached until 1960 within the Greenpos franchise area. j If normal or above normal rainfall occurs, then the crater supply will be-admquate. If on the other hand a series of extremely dry rears are experienced then there ' _ may be very little if any margin of safety. At the same timat it may be advisahls to check on the accuracy, as much as is possible under present conditions, of the 200 million gallons annual demand rate ascertained by the Fact Friers Committees The brief and feral study based to a certain extent on recharge con- ditions found elsewhere on Lona Island seems to indicate that an adequate supply can be obtained to meet the water-supply condition set forth in attachmmat A by the Fact Finders Committee. However, since the factor of safety is sell, a ,.� -. more detailed. investigation will need to be made and due consideration will need to be given to the proper schemes of developing the additional supply as efficient) as possible in the. Bast Marion area. In general9 the outflow to sea in the area .; 1 should be reduced to a -imams and thus a large percentage of the annual recchasge J to the underground sources should be captured. An in addition, artificial recharge as practiced by lir. Konsel near pumping station No. 3 could be expanded-to utilise the full flaw of the stresmlet that rues westerly from Silver Lake to Piper Cove."- Detailed studies may even show the desirability of recharging water pumped in hast Marion in the Greenport area during the winter and spring months. �. Addition to the water-supply plant should not consist of deep wells hart instead of a syttes that an mach as possible skims fresh water lying about the _ salt water found at greater depths below the land surtum of Greenport and Bast Marion. By proper design, salt water intrusion horizontally and upward frog ; underneath can be reduced and perhaps eliminated. Greenport vater has contained a chloride content of as high as 400 parts per million."
