INTRODUCTION The groundwater system on the north fork of Long Island, and especially in the easternmost hamlet of Orient, is a limited resource that requires proper management to prevent saltwater encroachments and ensure its future availability. This water quality, water quantity, and surface water impact study was prepared by P.W. Grosser Consulting (PWGC) under contract to Twomey, Latham, Shea, Kelley, Dubin & Quartararo LLP (TLKDQ LLP) to evaluate the hydrogeology of the area and determine if new private water well systems for the proposed subdivision are feasible. This report would also assist the developer in persuading the Town of Southold that a positive declaration under SEQRA is unwarranted. The result of this analysis is that the thin freshwater lens in the area is further reduced by the existence of a clay layer. According to the Suffolk County Department of Health Services (SCDHS) regulations, potential private water wells for the proposed subdivision are feasible provided that well spacing, separation distances to sanitary systems, and other design guidelines are met. PWGC's results of this study concluded that the proposed residential groundwater well systems are feasible to be installed at the site. Although the hydrogeology of the site presents some challenges, the separation distance between the established saltwater interface and the proposed bottom of the wells will be adequate to avoid saltwater upconing into the wells. The water quality investigation of the groundwater beneath the site reveals no apparent contamination. All the parameters tested as per the Suffolk County Department of Health Regulations are under the standards. 1. PURPOSE AND SCOPE OF THIS INVESTIGATION The scope of the study included the following components: 1) Research local geological and hydrogeological conditions for the site and surrounding area. 2) Research and review groundwater data of existing local nearby groundwater wells. Determine if Suffolk County Department of Health Services SCDHS variances have been granted for residential wells depths and screen settings due to saltwater conditions for wells in the area. 3) Review available environmental databases for potential sources of groundwater contamination. 4) Estimate water supply needs for the four lots based on single family residential applications. Estimate impact groundwater withdrawal will have on local aquifer conditions. Site recharge conditions will be evaluated against proposed annual withdrawal rates. 5) Evaluate the proposed well design for the proposed subdivision and analyze the impact of the water extraction on the hydrogeology beneath the site, especially the effects on the saltwater interface. 6) Estimate nitrogen loading to groundwater from the four proposed lots and its subsequent effect on the Long Island Sound. 7) Determine if the existing pond on proposed lot number four is from perched water or if there is a connection with the deeper hydrogeology of the area.

DESCRIPTION OF STUDY AREA The study area is a 22.9-acre agricultural and open space area located along the northern shore of the hamlet of Orient, Town of Southold. Currently, the property is unimproved with most of the main segment of the site occupied as a vineyard plantation. There are some landscaped areas on the north side and a 100 foot high bluff on the Sound dropping to the beach. There is an existing access paved road (extension of Heath Drive). Surrounding properties include residential improved lots to the east, south and southwest, unimproved residential lots to the west and south side, and the Long Island Sound to the north. See Figure 1 for an aerial photograph of the subject property and the surrounding area. The proposed development intends to subdivide the property into five lots. Four of the lots are intended to be developed with single family houses and the fifth lot would remain as an agricultural area with a structure to support vineyard operations.The residential lots would occupy the north landscaped areas of the site,while the proposed fifth lot would remain as an existing vineyard. See Subdivision Site Plan, Figure 2. B. HYDROGEOLOGY 1. INTRODUCTION Orient is one of five hydraulically isolated freshwater flow systems on the North Fork of Long Island. (U.S. Geological Survey). The subject property is located on a freshwater lens setting, meaning that shallow groundwater is freshwater, but deeper groundwater is saline due to encroachment from the surrounding seawater. If this freshwater lens were over utilized, the saltwater would further encroach upon it and the freshwater resource would become diminished. The subsurface beneath the site is composed of several layers of unconsolidated deposits and clay before bedrock is reached at an approximate depth of ±480 feet below sea level. The top layer is a Pleistocene-era glacial deposit, which is called the Upper Glacial Aquifer (UGA) below the water table. The top of this aquifer is the freshwater lens where the groundwater extraction wells are screened, and beneath that is saltwater. Beneath the UGA is the Magothy aquifer. Beneath the Magothy aquifer is the Raritan Clay, Lloyd aquifer, and bedrock, which are not relevant to this analysis due to their depth with relation to the prevalent saltwater interface in the area. The sections below describe each of the relevant formations and the freshwater-lens setting in detail. P.W. Grosser Consulting, Inc• P.W.

FRESHWATER-LENS SETTING A freshwater lens is a freshwater aquifer bounded laterally and below by saltwater. The freshwater lens occurs beneath Long Island's forks and barrier islands, as well as smaller islands such as Shelter Island and Ram Island. The freshwater is not connected to the rest of Long Island's aquifer system and so the only natural replenishment for the freshwater is precipitation. Due to density differences, the freshwater stays above the denser saltwater and forms a relatively static balance. When pumping occurs, the interface between the saltwater and freshwater can shift inward and even contaminate a supply well. The region that is normally freshwater that has become contaminated by saltwater due to pumping is called the zone of diffusion. See Figure 3 for a cross-section of a typical freshwater lens setting. (Cartwright 5, 8) 3. PLEISTOCENE GLACIAL DEPOSITS/UPPER GLACIAL AQUIFER The shallow geologic materials exposed at the surface consist of Pleistocene-age glacial outwash deposits. These materials were deposited some distance from the leading edge of the glacier and they consist of well-sorted sand and gravel. Below the water table, the Pleistocene deposits are designated as the UGA. Groundwater in the UGA exists under water-table, or "unconfined," conditions. The USGS estimated this aquifer to be approximately 85 feet thick beneath the project site. The average horizontal hydraulic conductivity of the UGA is estimated to be approximately 135 ft./day and the vertical hydraulic conductivity is approximately 15 ft./day. However, other studies in the North Fork show horizontal conductivity values much higher than the average up to 350 ft/day (Roy F. Weston of New York). The specific yield is estimated to be 0.20. Wells tapping the UGA on Long Island have yielded as much as 1,500 gpm, with reported specific capacities ranging from 20-30 gpm/foot of drawdown and higher. (McClymonds and Franke) The saltwater interface is within the UGA beneath the site. Due to the freshwater lens setting, the UGA is freshwater between 5 and 80 ft. amsl, and gradually decreases as it approaches the shore. The depth to each layer on the site area is described below. 4. MAGOTHY AQUIFER The Cretaceous-age Magothy aquifer lies beneath the upper glacial aquifer and consists predominantly of fine-to medium-grained sand with silty and clayey layers and lenses. The USGS estimates this aquifer to be approximately 120 feet thick beneath the project site, extending to a depth of 390 feet bgs. The average horizontal hydraulic conductivity of the Magothy aquifer is estimated to be approximately 65 ft./day and the vertical hydraulic conductivity is approximately 1.0 ft./day. The storativity is estimated to be 0.003. Wells tapping the Magothy aquifer on Long Island have yielded as much as the UGA but with somewhat lower specific capacities due to the higher percentages of silt and clay content in the Magothy aquifer.

HYDROLOGY 1. HYDROLOGIC CYCLE Water continuously flows between the atmosphere, the sea, the land surface, and the subsurface in a process called the hydrologic cycle. The cycle has no beginning or end, but for this report, precipitation will serve as the beginning. Rain, snow, and hail carry water from the atmosphere to the surface, where several actions may occur. Precipitation that falls on a water body is eventually re-evaporated. Precipitation that falls on the land may re-evaporate, be transpired back to the atmosphere by vegetation, run off the land surface to a body of water, or infiltrate the soil to become part of the groundwater flow system. Some groundwater is pumped to the surface through wells, where it is returned to the land surface either by the irrigation system or to the subsurface by sanitary systems. After the evapotranspiration processes, the cycle begins again with precipitation. (Nemickas and Koszalka 24) 2. PRECIPITATION Annual precipitation was recorded in nearby Bridgehampton from 1931 to 1976. Over the 45-year period, the maximum annual precipitation was 63.71 inches (1953), the minimum annual precipitation was 30.67 (1965), and the mean annual precipitation was 45 inches (Nemickas and Koszalka 27). Precipitation is evenly distributed throughout the year with no distinct wet or dry season on Long Island (Peterson 6). 3. EVAPOTRANSPIRATION The rate of evapotranspiration varies based on soil conditions, vegetation type, temperature, humidity, and other factors. Thornthwaite and Mather developed a method in 1957 to estimate evapotranspiration rates on Long Island (Peterson 9-10). This method was used to estimate the evapotranspiration rate on Long Island's South Fork from mean weather data from 1930 to 1975. The mean annual evapotranspiration rate is 23.2 inches with a maximum of 24.6 inches in 1959 and a minimum of 16.4 inches in 1957 (Nemickas and Koszalka 28-29, 32). Due to the proximity of the North and South Fork of long Island, the precipitation and evapotranspiration values of these reports are relevant to the subject site. 4. DIRECT RUNOFF The subject site and the surrounding areas have sandy soil and no nearby streams, so it is assumed that most of the precipitation is recharged to the soil or undergoes evapotranspiration. A minor amount of precipitation that falls onto the existing bluff fronting the Sound will not contribute to recharge and will runoff to the Sound. This area is approximately 2.7 acres.The total area contributing to recharge is then 22.9 cares less 2.7 acres or 20.2 acres. 5. GROUNDWATER RECHARGE The only source of freshwater to the groundwater system beneath the site and the surrounding areas is precipitation via infiltration through the unsaturated zone. This recharge is estimated as the difference between precipitation, evapotranspiration, and direct runoff. P.W. Grosser Consulting, Inc• P.W. Grosser Consulting Engineer&Hydrogeologist, PC 6 630 Johnson Avenue, Suite 7 • Bohemia, NY 11716 PH 631.589.6353 • FX 631.589.8705 •www.pwgrosser.com New York, NY• Syracuse, NY• Seattle, WA TLS1601 Aquifer Quantity&Quality Analysis PWGG Aa Orient, New York Strategic Enviran mental Engineering Solutions November 2016(Revision 1:April 2017) Recharge=Precipitation—Evapotranspiration—Direct Runoff Five scenarios have been analyzed to simulate the potential hydrology and the impact of the recharge conditions on the site. The five scenarios are explained below and a water budget analysis is presented in Section C7 to quantify the recharge amount. • Average conditions: Average precipitation (45 in/yr) and average evapotranspiration (23.2 in/yr) • Drought Conditions: Low precipitation (30.67 in/yr) and high evapotranspiration (24.6 in/yr) • Drought Conditions: Low precipitation (30.67 in/yr.) and low evapotranspiration (16.4 in/yr.) • High Recharge Conditions: High precipitation (63.71 in/yr.) and high evapotranspiration (24.6 in/yr.) • High Recharge Conditions: High precipitation (63.71 in/yr.) and low evapotranspiration (16.4 in/yr.) 6. GROUNDWATER CONSUMPTION The proposed subdivision will require installing four individual private water wells (one per lot) to supply domestic water and irrigation for the proposed single family dwellings. The average daily domestic water demand is estimated to be between 80 to 100 gallons per day per capita (U.S. Geological Survey). The average domestic water demand per dwelling is between 280 to 350 gpd (3.5 capita per dwelling). The projected annual consumption rate for the site is 1,400 gpd. 4 dwellings X 100 gpd/capita X 3.5 capita/dwelling = 1,400 gpd 40 percent of the total projected annual consumption is expected to be lost mostly to irrigation (consumptive water use).The total net recharge loss to the aquifer is then 560 gpd. 0.4 x 1,400 gpd =560 gpd The "permissible sustained yield" denotes the maximum rate at which groundwater can be withdrawn on a regional, long-term basis without causing adverse impacts on groundwater or ecological resources. For the Town of Southold, a permissible sustained yield of 0.25 mgd/sq. mi. has been presented as suitable in the past (ERM-Northeast Engineers, Camp Dresser& Mckee and Suffolk County- Department of Health Services). This yields a permissive sustained yield of 390 gpd/acre: 250,000 gpd/sq. mi. X 1/640 sq. mi./acre=390 gpd/acre The total permissive sustained yield for the site is 7,900 gpd: 390 gpd/acre X 20.2 acres =7,878 gpd or 7,900 gpd The projected consumptive water use for the site will be only 7 percent of the permissive sustaining yield. 560 gpd/7,878 gpd =0.07 This factor of safety is more than adequate to ensure the protection of the quantity of the water resources of the area.

WATER BUDGET The water budget for the subject site is the total amount of water that is added to or withdrawn from the aquifer. In addition to the groundwater recharge equation shown in Section C5 (Recharge = Precipitation — Evapotranspiration — Direct Runoff), the consumptive water use must also be deducted from the total net recharge volume flowing back to the aquifer. Depending on the hydrologic conditions during any given year, there are many conditions that affect the overall recharge to the aquifer. These hydrologic conditions are explained in detail below and are summarized in the Table 1. a. Average Conditions In an average year, the total expected water budget is a surplus of approximately 1.34 million cubic feet of water recharge into the ground (±10.05 million gallons). Under groundwater surplus conditions, groundwater level will rise to a steady-state condition, leading to a greater hydraulic gradient. This causes an underflow towards the Sound and a downward movement of the saltwater interface until the system reaches a new equilibrium. b. Drought Conditions In a year with low precipitation and high evapotranspiration, groundwater recharge is low and the total amount is approximately a surplus of 0.18 million cubic feet of water (±1.32 million gallons). In a similar low scenario, when the precipitation is low and the evapotranspiration is low, the expected groundwater recharge is approximately a surplus of 0.86 million cubic feet of water (±6.42 million gallons). c. High Precir)itation At the other extreme is a year with high precipitation and high evapotranspiration, groundwater recharge is high and the total amount is approximately a surplus of 2.60 million cubic feet of water (±19.44 million gallons) recharged to the ground. In a similar low scenario, when the precipitation is higher than the average and the evapotranspiration is low, the expected groundwater recharge is approximately a surplus of 3.28 million cubic feet of water(±24.54 million gallons).

BOUNDARY BETWEEN FRESH AND SALINE GROUNDWATER The groundwater beneath the Orient land mass can be considered as an island setting that is isolated from the rest of the North Fork aquifer system. Shallow groundwater beneath Orient is freshwater due to its origin as precipitation and deeper groundwater is saline due to its connection with surrounding sea waters. The depth to the saltwater interface is deepest in the center of the land mass and becomes shallower towards the edges. The shape of the saltwater interface resembles a concave water table P.W.

The saltwater interface tends to be symmetrical and opposite to the contours lines of the water table which approach to 0 ft. amsl as it gets close to the Sound. The Sound is for the purpose of this study considered the groundwater elevation of 0 ft. amsl and saltwater interface depth of 0 ft. bgs. The saltwater interface will be shallower beneath pumping wells due to an effect called upconing. This upconing effect is a rise of the saltwater below the pumps and occurs as a consequence of the drawdown around a well which lowers the pressure of the freshwater lens above. If the well screen is close to the saltwater interface and the well flow rate is high enough potential encroachment of saltwater to the well can occur. The upconing effect will be stable once it reaches an equilibrium point. See Figure 4 for a diagram of a freshwater lens with upconing due to a pumping well. (Nemickas and Koszalka 49, 52). 1. GHYBEN-HERZBERG RELATIONSHIP Freshwater is less dense and therefore "floats" above saltwater. According to the Ghyben-Herzberg principle, the depth of fresh water below sea level is proportional to the height of fresh water above sea level by an amount determined by the difference in density between fresh water and saltwater. Under ideal conditions and based on standard density conditions, freshwater extends 40 feet below sea level for each foot of fresh water above sea level. (Nemickas and Koszalka 42, 46-48) The geologic layers of Long Island are layered horizontally, which results in hydraulic conductivity that is generally greater in the horizontal direction than it is in the vertical direction. This effect, called anisotropy, means that in general water flows horizontally easier than it does vertically. Anisotropy causes the saltwater interface to be at a higher altitude than the Ghyben-Herzberg relationship would otherwise predict. (Nemickas and Koszalka 48-50) Another mitigating factor to the Ghyben-Herzberg relationship is the site location, which may be tidally influenced. With each tidal cycle, saltwater is effectively pushed in and out of the subsurface beneath the site. This has the effect of further decreasing the depth to the saltwater interface. Due to these reasons, the estimates of the Ghyben-Herzberg relationship may not be adequate to estimate the thickness of the freshwater lens on the site. E. DEPTH OF SALTWATER INTERFACE 1. EXISTING INFORMATION The test well by Casola Well Drillers Inc. dated January 21, 2013 (EW-1) was located on the southwest side of the proposed Lot No. 3. This test well is shown in Figure 2 and the well information provided to PWGC shows that the test hole reached to a depth of 90.0 ft. bgs (-23.0 ft. amsl) without encountering saltwater. The Ghyben-Herzberg relationship described in the previous section estimates the elevation of the saltwater interface to be -200 ft. amsl (40 X 5.0 ft.). This estimate is in conflict with the published USGS reports that describe the saltwater interface at a much higher elevation (approximately at -70 ft. amsl) at the center of the Orient land mass (U.S. Geological Survey).

A USGS hydrogeology report was used to extrapolate an estimated depth of the saltwater interface at the site (U.S. Geological Survey). The USGS report provides a scaled cross section of the hydrogeology of the area. This cross section is laterally across the North Fork (west to east). The deepest saltwater interface section on Orient is approximate -75.0 ft. amsl at the location of borehole 53337 which is approximately at the center of Orient land mass. This saltwater depth at the center of Orient land mass and the Sound were used as the known points to generate a plot of the saltwater interface with the subject site laying on the same plot line (420 feet from the shore). A data point transect showing the known points is shown in Figure 5. A parabolic line is plotted between the two known points and by extrapolation, the saltwater interface depth below the existing test well EW-1 of -38.7 ft. amsl was obtained at the subject site. The thickness of the freshwater lens is estimated to be 43.7 ft. (5 + 38.7) or 44 ft. approximately, so the depth to the saltwater interface is approximately 106 feet bgs. A diagram showing the known points and the saltwater interface plot lines are provided in Figure 6 The estimated depth of the saltwater interface at -75 amsl beneath the Orient land mass is further confirmed by a report by ERM-Northeast Engineers et al. (1983). 2. FIELD EXPLORATION The professional services of Peconic Well Drillers (Peconic) were retained by the property owner in order to further investigate the site's subsurface conditions. The investigation sought to confirm the elevation of the groundwater table, and the thickness and depth of the confining layers as shown on the existing test well information EW-1. Additionally, the field investigation was mainly targeted to define the depth of the saltwater interface. On Thursday, August 18th, 2016, PWGC and Peconic began to drill a test well (13-1) in Lot No. 3 as shown in Figure 2. The test well was performed using the reverse rotary mud drilling method. The top of the test hole was located at elevation 68' amsl based on the topographic information shown on the site's Preliminary Plat Plan by Young & Young Land Surveyors, dated August 17, 2015, and revised September 20, 2015. Groundwater was encountered at 63' bgs (5.0' amsl) which matches the information of the nearby existing test well EW-1. Subsurface soil samples were collected using the continuous split spoon sampling technique starting at the groundwater table and ending at a depth of 116' bgs (-48' amsl). Groundwater was extracted from each saturated soil sample using a CO2-pressurized filter press and tested for conductivity and salinity using an Oakton PCD650 water meter. Additionally, two (2) water samples were submitted to a testing laboratory to examine total Chloride content. The boring log for the test hole can be found in Appendix A, and the test hole profile is shown in Figure 7. The geology of the immediate vicinity as indicated on the test hole profile shows an approximate 13 foot thick saturated sandy layer below the water table (5.0' amsl) to an elevation of -8.0' amsl. Underlying this sandy layer there is a combination of silty sand, sandy clay and clay materials that form the confining layer. The test hole reached to a depth of 116' bgs (-48' amsl) and did not penetrate the confining layer. The conductivity and salinity water field samples conducted by PWGC indicate that the saltwater interface is located at approximately 108' bgs (-40' amsl). These field test results were further validated P.W. Grosser Consulting, Inc• P.W.

AMSL The saltwater interface information and general geology of test hole B-1 were confirmed with the assistance of geophysical logs (gamma, resistivity& sp) conducted to the full depth of the test hole. See Appendix C. On Friday, August 261h 2016, three additional test holes (13-2 to 13-4) were conducted south of the test hole B-1 in order to explore the possibility of finding a water-bearing layer (saturated sandy soil) thick enough to comply with the SCDHS "Private Waters System Standards" (Sec. §406.4-12(6), Table 4 (6) — Specific Test Well Requirements for Realty Subdivision). Among other requirements of this section, the top of the well screen must be at least 20 ft. below the static water level. Test hole B-2 was drilled approximately 180 ft. southeast from B-1 on lot No. 4. B-3 was drilled near the center point of the proposed cul-de-sac and B-4 was drilled on the border between lot No. 1 and lot No. 5.

Six additional test borings were attempted to be conducted in the southeast area of Lot 3, however, the driller encountered boulders at approximately 15 -20 ft. bgs that could not be penetrated by the equipment being used. F. PROPOSED WELL DESIGN SCDHS published the "Private Waters System Standards" document (the standards) to regulate the design and construction of private water wells in Suffolk County. Typical residential water wells are required to have a minimum depth of 50 ft., with at least 40 ft. between the top of the well screen and the water table. If the design of the proposed wells would follow these general construction requirements, the proposed well screen would penetrate below the saltwater interface and into unsatisfactory water quality. Option 6 of Table 4 of the standards (Alternatives When Test Well Water Quality is Unsatisfactory) provides exceptions for Realty Subdivisions (5 lots or more) to the general well construction standards. This option allows for only 20 ft. of static groundwater above the top of the well screen. As part of the field exploration, a 4-inch diameter well was installed on the south side of test hole B-1. The new test well TW-1 reached to a depth of 79' bgs with the last 4 feet of screen. The water table was located at 54 ft. bgs (1.0' amsl), which provides 21 ft. of static water above the top of the screen. See Figure 8. A pump test of this well was performed to obtain the capacity of the aquifer for yielding water. Under the SCDHS "Private Waters System Standards", the minimum continuous yield of 5.0 gpm must be supplied for residential dwellings and an additional 5.0 gpm for each additional dwelling. The well was flushed and purge at a continuous flow before the pump test and after approximately a period of one (1) hour, a flow measurement was taken which indicated a yield of approximately 20 gpm. At this point, the pump test was terminated and groundwater samples were collected to test the water quality. At the maximum anticipated flow rate of 10 gpm per well, the estimated upconing of the saltwater interface will rise 3.2 ft. at the center of the cone. The estimate is based on average horizontal hydraulic conductivities values (Kx) of 270 ft./day which was obtained from other reports of the vicinity of the site (Roy F. Weston of New York) Under proposed conditions, there will be approximately 15 ft. of separation distance between the highest expected saltwater interface and the bottom of the screen. P.W. Grosser Consulting, Inc• P.W. Grosser Consulting Engineer&Hydrogeologist, PC 13 630 Johnson Avenue, Suite 7 • Bohemia, NY 11716 PH 631.589.6353 • FX 631.589.8705 •www.pwgrosser.com New York, NY• Syracuse, NY• Seattle, WA TLS1601 Aquifer Quantity&Quality Analysis PWGG Aa Orient, New York Strategic Enviran mental Engineering Solutions November 2016(Revision 1:April 2017) This estimated value is very sensitive to the change in hydraulic parameters of the section of the aquifer. The location of test well TW-1 was chosen after taking into consideration the separation distances to existing neighboring sanitary systems. The location of the proposed wells for the other lots must be conducted as an intricate part of the site planning of the proposed sites to take into considerations the required separation distances to other private water wells and sanitary systems of adjacent properties. As per the Suffolk County Water Authority records, most of the properties adjacent to the subject site are not connected to any community water distribution system, therefore, it is assumed that most of these properties rely upon on-site well water to meet their domestic needs. G. WATER QUALITY On September 21, 2016, water samples were collected from test well TW-1 and sent to Long Island Analytical Laboratories, Inc. for testing. The results are shown in Appendix D of this report and indicated that the parameters analyzed were below the standards, except for the positive results of Coliform Bacteria. The presence of Coliform bacteria in the water quality results was greatly attributed to a cross contamination during the drilling operations, transportation or laboratory handling. On October 06, 2016, the test well TW-1 was chlorinated as per the SCDHS guidelines and then retested for Total Coliform. The results show the absence of Total Coliforms or E. Coli Bacteria (Appendix E). Groundwater samples were also previously collected from the test well by Casola and tested for common water chemistry by Long Island Analytical Laboratories, Inc. in November of 2013. These samples were also found with concentrations below the standards. See results in Appendix F. Saltwater intrusion is the most relevant source of chlorides in the groundwater. Federal and state standards recommend that chloride content should not exceed 250 mg/L. The result show a chloride concentration of 20.9 mg/I at test well TW-1 which is significantly lower than the standard. The field investigation was able to determine the depth of the saltwater interface which is not expected to pose a potential for upconing at the SCDHS specified flow rates (10 gpm maximum). Nitrate in groundwater typically originates from decaying organic material, sanitary system effluent, and fertilizers. Federal and state standards recommend that nitrate concentrations remain below 10 mg/L. The proposed water wells should be located as per the recommended separation distances to sanitary systems to avoid increasing nitrate concentrations. (Nemickas and Koszalka 44). The nitrate concentration in the test well is below the standard (7.20 mg/1), however, higher than the standard concentrations have been recorded in the nearby USGS wells (USGS S-54830.1, and S-54831.1). These wells are located approximately 2,500 ft. south of the site and the groundwater most likely flows towards the south shore of Orient.The values were observed in 1975 and 1976. Iron and manganese tend to occur at higher concentrations on the South Fork of Long Island, but the Federal standards are in place for aesthetic rather than health reasons. Both minerals typically originate from dissolved rocks and soils and both can adversely affect the taste of drinking water or can stain laundry, plumbing fixtures, and irrigation areas. At high levels, iron can cause growth of iron-reducing bacteria in the wells and inside plumbing. New York State standards recommend that iron and manganese should not exceed 0.3 mg/L, or a combined value of 0.5 mg/L. The test well results show values below the standards. P.W.

Apparently, these wells were also impacted with Aldicarb and Dacthal above the Health Department concentrations. None of these chemicals were found to exceed the standards in the water quality tests conducted in 2016. 1. ENVIRONMENTAL RECORD SOURCES Environmental Data Resources (EDR) of Southport, Connecticut was retained to provide a computerized database search of the project area within an ASTM-standard radius of the subject property. A list of the databases searched and the search radius is shown in the summary table below. PWGC reviewed the database output to determine if the property appears on any of the regulatory agency lists. Detailed information concerning each database list is provided in the EDR report(Appendix G). The environmental document search performed by Environmental Data Resources, Inc. (EDR) indicates that from the database search performed, one record was found within the one-mile radius search performed. The record was from the State LTANKS records and consisted of a closed spill report of 0.00 gallons of#2 fuel oil 0.346 miles from the site that occurred on 12-08-1994.

Nitrogen Loading Calculations a. Purpose Nitrogen is a natural and necessary nutrient found in the environment; however excessive quantities of nitrogen, typically in the form of nitrate (NO3), can be harmful to the humans and the ecosystem. High concentrations of nitrate in drinking water supplies can lead to methemoglobinemia, a disease that is caused by the intake of nitrates, which are reduced into nitrite (NO2) and bind with hemoglobin in the blood, preventing oxygen from being carried to bodily tissues. Methemoglobinemia is also known as blue baby syndrome since it causes infants to have a blue coloration of the skin due to the lack of oxygen. As a result, the maximum contaminant level (MCL) of nitrate in drinking water has been set to 10 milligrams per-liter (mg/L). In the environment, high concentrations of nitrogen have been shown to cause eutrophication in surface water bodies, leading to harmful algal blooms, loss of seagrass and estuarine habitat, low dissolved oxygen conditions, and fish kills. Long Island has been designated as a sole source aquifer system, as it derives 100 percent of its drinking water from groundwater. In addition, nitrogen originating from the aquifer system ultimately discharges to surrounding surface water bodies. Significant sources of nitrogen loading are caused directly by human activity from sources such as waste water discharge and agriculture. This can affect the rates and concentrations at which nitrogen is transported through the groundwater system. Therefore, PWGC has evaluated the potential nitrogen loading in groundwater recharge from the proposed development. P.W. Grosser Consulting, Inc• P.W. Grosser Consulting Engineer&Hydrogeologist, PC 16 630 Johnson Avenue, Suite 7 • Bohemia, NY 11716 PH 631.589.6353 • FX 631.589.8705 •www.pwgrosser.com New York, NY• Syracuse, NY• Seattle, WA TLS1601 Aquifer Quantity&Quality Analysis PWGC Aa Orient, New York Strategic Enviran mental Engineering Solutions November 2016(Revision 1:April 2017) Additional precautions are incorporated with the use of innovative or advanced septic systems that can minimize nitrogen loading through pre-treatment. The Suffolk County Department of Health Services (SCDHS) has recently adopted Article 19 and revised their residential construction standards to allow for voluntary the use of Innovative and Alternative On-Site Wastewater Treatment Systems (I/A OWTS). Currently the SCDHS has approved two units, the Hydro-Action and the Norweco Singulair systems. Both systems demonstrated the ability to reduce nitrogen in the effluent waste stream to below 19 mg/L. It is the intention of the owner to utilize and I/A OWTS on each of the four lots in this subdivision. The owner will select one of the approved systems from SCDHS, when the applications are submitted the SCDHS. b. Nitrogen Mass Balance Prediction PWGC has evaluated the expected nitrogen loading to groundwater from the proposed development using the BURBS model. The BURBS model, developed at Cornell University by Hughes et al. (1985), is a computer simulation program that computes the potential impact of a proposed development on groundwater within a community due to nitrogen. Cornell University has developed this model for specific application on Long Island. For comparative purposes, PWGC has prepared a BURBS computation for the existing conditions and proposed development. Based on PWGCs experience, this program will predict a conservative estimate of nitrogen recharged to groundwater. It calculates loadings from wastewater, turf, natural land, atmospheric deposition, and runoff from impervious surfaces. The Burbs model predicts nitrogen leached to groundwater independent of land area (i.e.: lbs N/acre/year). In order to calculate the estimated mass of nitrogen leached to groundwater, the acreage of each of the project components is multiplied by the model output, yielding pounds of nitrogen per year.The parameters used in the Burbs model include: 1. Fraction of Land in Turf 2. Fraction of Land which is impervious 3. Average persons per dwelling 4. Housing density 5. Precipitation rate 6. Water recharged from turf 7. Water recharged from natural land 8. Evaporation from impervious surface 9. Runoff from impervious recharged 10. Home water use per person 11. Nitrogen concentration in precipitation 12. Nitrogen concentration in water used 13. Turf fertilization rate 14. Fraction of nitrogen leached from turf 15. Fraction of wastewater N lost as gas 16. Wastewater fraction removed by Sewer 17. Nitrogen per person in wastewater 18. Nitrogen removal rate of natural land. P.W. Grosser Consulting, Inc• P.W. Grosser Consulting Engineer&Hydrogeologist, PC 17 630 Johnson Avenue, Suite 7 • Bohemia, NY 11716 PH 631.589.6353 • FX 631.589.8705 •www.pwgrosser.com New York, NY• Syracuse, NY• Seattle, WA TLS1601 Aquifer Quantity&Quality Analysis PWGG Aa Orient, New York Strategic Enviran mental Engineering Solutions November 2016(Revision 1:April 2017) Each of these parameters is discussed and model inputs are defined. The demographic type parameters (i.e.: land areas, persons per dwelling, etc.) were derived information provided by TLKDQ LLP. For the purpose of executing the Burbs model and due to the complexity of the project, land areas of similar type and/or usage were combined and run independently. The results were then summed to give the overall nitrogen leached to groundwater. Fraction of Land in Turf, Impervious, and Natural The fraction of land in turf refers to areas maintained as lawn and/or as agriculture. The fraction of land which is impervious is the sum of roof areas, driveways, and roads. Both the fraction of land in turf and impervious must be between 0 and 1. The fraction of land in natural vegetation is computed as 1 minus the sum of the fraction in turf and impervious, thus the sum of these must be less than 1 (BURBS). Land areas for the existing conditions and proposed development were given from information provided by TLKDQ LLP or derived from other sources such as recent aerial imagery and the United States Department of Agriculture (USDA) Urban Hydrology for Small Watersheds TR-55 manual. Average Persons per Dwelling The average number of people living in each house or dwelling unit (BURBS). As described in Section 6 of this report, 3.5 persons are estimated to occupy each single family home. Housing Density The number of dwelling units per acre (BURBS).The housing density used for the proposed development was 0.6 houses per acre. This value was based on four single family homes being developed on four separate lots. The total area of the four lots is approximately 6.66 acres. 4 homes/6.66 acres = 0.6 homes/acre. It should be noted that the remaining project area includes land that is to be conserved as open space. For the purposes of running the BURBS model for the proposed development, the land to be conserved was calculated separately. Precipitation Rate The annual average precipitation in inches (BURBS). A value of 45 inches was used for this project as described in Section C-2 of this report. Water recharged from Turf and Natural Land The amount of water per unit area of turf which drains to groundwater (BURBS). A value of 22 inches was used for this project, slightly less than half of total rainfall. See section C-5 of this report. Evaporation from Impervious Surfaces The fraction of precipitation falling on impervious surface assumed to evaporate (BURBS). A value of 0.1 was used for each of the models run.This amount is recommended by the Burbs parameter description. Runoff from Impervious Recharged The fraction of the runoff which is recharged through recharge basins, ponds, etc (BURBS). Evaporation is subtracted. All of the runoff for this project area will be directed to the subsurface. Therefore, a value of 1 was used in each of the models run. P.W. Grosser Consulting, Inc• P.W.

The value used here was 100 gallons per person. This value was based on U.S. Geological Survey estimates of daily domestic water demand between 80 to 100 gallons per day per person. See section C-6.a of this report. This is a conservative estimate and includes all water uses such as bathing, cooking, cleaning, sanitary, irrigation, etc. Nitrogen Concentration in Precipitation Average concentration. The Burbs models recommend using data from the closest weather station where nitrogen tests were taken (BURBS). An average value of .75 mg/L was used in each of the Burbs models run. This was derived from the National Atmospheric Deposition Program NTN Site NY96 - Cedar Beach, Southold, New York. Concentration of nitrate (NO3) were given for the years 2004 through 2014, ranging from .62 mg/L to .9 mg/I. Nitrogen Concentration in Water Used Average concentration in water used in homes (BURBS). A value of 5.47 mg/L was used when running each of the models. This value was obtained from groundwater analysis performed in a test well at the proposed site in 2014.The Suffolk County Water Authority(SCWA)2014 Drinking Water Quality Report- Distribution Area 30 reported an average concentration of nitrogen of 5.38 mg/L. Turf Fertilization Rate Average yearly nitrogen application rate expected from residential turf (BURBS). The turf fertilization rate was also used to estimate nitrogen in recharge from agricultural areas. The parcel which is being preserved as a natural land conservation area is currently comprised of vineyards and will remain vineyards following development. Based upon PWGCs experience and a white paper published jointly by The Nature Conservancy and the Peconic Estuary Program, vineyards have a much lower fertilizer application rate. A value of 0.17 pounds per 1000 square feet was used for the vineyards (Lloyd, 2014). A value of 2.13 pounds per 1000 square feet was used for residential lawns. These values were derived from information provided by the Cornell Cooperative Extension. Fraction of Nitrogen Leached from Turf The fraction of nitrogen applied from fertilizer, precipitation, etc. which leached to groundwater. The Burbs model recommends 0.35 for sandy soil if clippings are removed, or 0.5 if clippings are left on turf. These values are based on Long Island studies Hughes, Henry B.F. and K.S. Porter. 1983. Land Use and Ground Water Quality in the Pine Barrens of Southampton. Center for Environmental Research, Cornell University, Ithaca, N.Y. and Hughes, Henry B.F., J. Pike and K.S. Porter. 1985. Assessment of Ground- Water Contamination by Nitrogen and Synthetic Organics in Two Water Districts in Nassau County, N.Y. Center for Environmental Research, Cornell University, Ithaca, N.Y. The value of 0.35 was used for existing farm lands and residential areas. Fraction of Wastewater Nitrogen Lost as Gas The fraction of nitrogen in wastewater which volatilizes or is converted to gaseous nitrogen through denitrification. Roughly 0.25 using typical onsite wastewater treatment systems under Long Island, New York conditions (BURBS [5]). A value of 0.25 was used in the proposed residential development model. P.W.

Fraction of Wastewater Removed by Sewer The efficiency of sewer systems. If no sewers are present use 0 (BURBS). As described above, typical onsite wastewater treatment systems will be used as part of this development;therefore, a value of 0 was used for this parameter when running the residential development model. Nitrogen per Person in Wastewater The average in the United States is 10 pounds per person per year (BURBS).This value was used when running the Burbs models. Nitrogen Removal Rate of Natural Land The fraction of nitrogen in precipitation which is removed by natural land before the water is recharged. Should be at least 90 percent (BURBS). Based upon the recommendations made by the Burbs parameter description, a value of 0.9 was used when running the BURBS Model. Summary of BURBS Model Results As described above, PWGC utilized the BURBS model to estimate the nitrogen output from the existing conditions and the proposed development. Summarized results are shown in Table 5. The detailed model calculations are included as Appendix H. Table 5 Summary of Nitrogen Loading Residences: 4 N Conc. In Innovative/Alternative lbs N/yr Recharge (mg/L) Septic Systems Existing Conditions 95.49 0.78 Proposed Development 260.88 1.93 Net Change 165.39 1.14 With the inclusion of the SCDHS-approved Innovative and Alternative On-Site Wastewater Treatment Systems (I/A OWTS), the modeling results indicate that the proposed development will increase the mass of nitrogen recharged to groundwater by approximately 165.4 pounds per year.The concentration of nitrogen in recharge will increase from 0.78 mg/L to approximately 1.93 mg/L. This value is a 20% reduction when compared to a subdivision with four (4) residences using conventional septic systems. Overall,the net change in nitrogen concentration within recharged groundwater would be 1.14 mg/L. As stated above, recent monitoring well sampling data and the 2014 Suffolk County Water Authority Water Quality Report indicate a background concentration of nitrogen of 5.47 and 5.38 mg/L respectively. In addition, the current MCL for nitrogen set by the Suffolk County Department of Health Services is 10 mg/L. Based on the estimated mass of nitrogen added to the groundwater system, and the increased concentration of nitrogen in groundwater recharge, and taking into consideration existing background conditions, PWGC believes that the proposed development will have a minimal adverse impact on both the groundwater quality and surrounding water bodies.

Perched Water Pond The site contains a small surface water pond of approximate 1,500 sq. ft. located on the proposed Lot number 4. According to the proposed Preliminary Plat Plan by Young & Young Land Surveyors, dated August 17, 2015, and revised September 20, 2015, the pond surface water elevation is estimated to be approximately 41.0 ft. amsl. No depth to the bottom of the pond is available; however, it is not expected to be very deep. The groundwater depth beneath this pond is expected to be at a minimum of 36 ft. bgs (5.0 ft. amsl). The separation distance between the water table and the bottom of the pond is significantly large to disprove a possible hydrological connection between the pond and the deeper hydrogeology of the area. The surface water pond is most likely lying on a localized confining layer that restricts the natural downward recharge flow (perching layer). P.W. Grosser Consulting, Inc• P.W.

The saltwater interface is deepest at the center of the land mass of Orient and it gets more shallow as it moves closer to the Sound. The saltwater interface beneath the site is estimated to be around -38.0 amsl, which provides a viable freshwater lens for the installation of low flow, private water wells. - The water quality beneath the subject site has been extensively tested and shows the parameters below the standards. Information of the near-by water wells of Brown Hills Estates have been contaminated with pesticides and herbicides in the past (Aldicarbs and Dacthal), however, there is no indication that these compounds are exceeding the water quality standards at the subject site. If at a later date, the proposed wells are impacted with these contaminants, there are many technologies on the market that could be implemented to residential water supply systems to mitigate the possible adverse water quality of the site (Reverse Osmosis,Activated Carbon Filters, etc.) - The water budget analysis of the site conducted with multiple hydrologic scenarios shows a surplus of the net recharge to the aquifer. This result supports the concluding argument that private water wells are feasible to be installed at the site, provided that the final design is well coordinated with the well spacing and setback requirements and that the assumed aquifer parameters in this report are confirmed in the field. - PWGC believes that the hydrogeology of the site presents challenges for the design and construction of the proposed private water wells and it is conscious of the severe water supply difficulties that the North Fork region of Long Island has been through. However, the proposed land subdivision reflects a responsible development approach that will have a negligible impact on the overall groundwater condition of the region. By following the design guidelines that the regulatory agencies have laid out and the most conservative engineering practices, the proposed low flow private wells could be implemented in a safe and responsible manner. - PWGC believes that a full-scale SEQRA evaluation is not warranted. The site has extensive water quality data to determine that the proposed low flow private water wells are viable. P.W. Grosser Consulting, Inc• P.W.

Upconing is caused by pumping water from a single point in the freshwater lens. The saline water beneath the well is affected and pulled upward towards the well. A higher flow rate will have a greater effect on the location of the saltwater interface and so the use of multiple wells with lower flow rates will have a lesser chance of upconing. • Wells should be spaced evenly and as far from the edge of the shore as possible to minimize saltwater intrusion. Other existing private water wells in the vicinity of the site must also be accounted for in the design process. • The SCDHS will require that additional test wells be conducted (one per lot) to confirm that the water well installation can be achieved in accordance with the construction guidelines. • Best Management Practices (BMP's) and Agricultural Environmental Management (AEM) practices for sustainable viticulture operations and pesticide management were added to the report in Appendix I. An impact assessment of prior pesticide use on potable groundwater was included as well. The recommendations focus on a voluntary, self-assessment tool that provides vineyard management guidance on the following topics: soil management, nutrition management, irrigation management, continuing education and weed, pest and pesticide management. By following these program, the vineyard operators can shape their procedures to manage pesticide leaching and avoid potential impacts to potable groundwater sources. P.W.

EPA Environmental Protection Agency. LCS Laboratory Control Sample:A sample matrix,free from the analytes of interest,spiked with verified known amounts of analytes or a material containing known and verified amounts of analytes. LCSD Laboratory Control Sample Duplicate:Refer to LCS. LFB Laboratory Fortified Blank:A sample matrix,free from the analytes of interest,spiked with verified known amounts of analytes or a material containing known and verified amounts of analytes. MDL Method Detection Limit:This value represents the level to which target analyte concentrations are reported as estimated values,when those target analyte concentrations are quantified below the reporting limit(RL).The MDL includes any adjustments from dilutions,concentrations or moisture content,where applicable. MS Matrix Spike Sample:A sample prepared by adding a known mass of target analyte to a specified amount of matrix sample for which an independent estimate of target analyte concentration is available. MSD Matrix Spike Sample Duplicate:Refer to MS. NA Not Applicable. NC Not Calculated: Term is utilized when one or more of the results utilized in the calculation are non-detect at the parameter's reporting unit. NDPA/DPA -N-Nitrosodiphenylamine/Diphenylamine. NI Not Ignitable. NP Non-Plastic:Term is utilized for the analysis of Atterberg Limits in soil. RL Reporting Limit: The value at which an instrument can accurately measure an analyte at a specific concentration.The RL includes any adjustments from dilutions,concentrations or moisture content,where applicable. RPD Relative Percent Difference: The results from matrix and/or matrix spike duplicates are primarily designed to assess the precision of analytical results in a given matrix and are expressed as relative percent difference(RPD). Values which are less than five times the reporting limit for any individual parameter are evaluated by utilizing the absolute difference between the values;although the RPD value will be provided in the report. SRM Standard Reference Material:A reference sample of a known or certified value that is of the same or similar matrix as the associated field samples. STLP Semi-dynamic Tank Leaching Procedure per EPA Method 1315. TIC Tentatively Identified Compound:A compound that has been identified to be present and is not part of the target compound list(TCL)for the method and/or program.All TICS are qualitatively identified and reported as estimated concentrations. Footnotes 1 The reference for this analyte should be considered modified since this analyte is absent from the target analyte list of the original method. Terms Total:With respect to Organic analyses,a'Total'result is defined as the summation of results for individual isomers or Aroclors.If a'Total' result is requested,the results of its individual components will also be reported.This is applicable to'Total'results for methods 8260,8081 and 8082. Analytical Method:Both the document from which the method originates and the analytical reference method.(Example:EPA 8260B is shown as 1,8260B.)The codes for the reference method documents are provided in the References section of the Addendum. Data Qualifiers A Spectra identified as"Aldol Condensation Product". B The analyte was detected above the reporting limit in the associated method blank.Flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times(10x)the concentration found in the blank.For MCP-related projects,flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times(10x) the concentration found in the blank.For DOD-related projects,flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times(10x)the concentration found in the blank AND the analyte was detected above one-half the reporting limit(or above the reporting limit for common lab contaminants)in the associated method blank.For NJ- Air-related projects,flag only applies to associated field samples that have detectable concentrations of the analyte above the reporting limit.For NJ-related projects(excluding Air),flag only applies to associated field samples that have detectable concentrations of the analyte,which was detected above the reporting limit in the associated method blank or above five times the Report Format: DU Report with'J'Qualifiers AHA- Page 13 of 17 Serial No:08251611:50 Project Name: ORIENT WELL Lab Number: L1626531 Project Number: TLS1601 Report Date: 08/25/16 Data Qualifiers reporting limit for common lab contaminants(Phthalates,Acetone,Methylene Chloride,2-Butanone). C Co-elution:The target analyte co-elutes with a known lab standard(i.e.surrogate,internal standards,etc.)for co-extracted analyses. D Concentration of analyte was quantified from diluted analysis.Flag only applies to field samples that have detectable concentrations of the analyte. E Concentration of analyte exceeds the range of the calibration curve and/or linear range of the instrument. G The concentration may be biased high due to matrix interferences(i.e,co-elution)with non-target compound(s).The result should be considered estimated. H The analysis of pH was performed beyond the regulatory-required holding time of 15 minutes from the time of sample collection. I The lower value for the two columns has been reported due to obvious interference. M Reporting Limit(RL)exceeds the MCP CAM Reporting Limit for this analyte. NJ Presumptive evidence of compound.This represents an estimated concentration for Tentatively Identified Compounds(TICS),where the identification is based on a mass spectral library search. P The RPD between the results for the two columns exceeds the method-specified criteria. Q The quality control sample exceeds the associated acceptance criteria.For DOD-related projects,LCS and/or Continuing Calibration Standard exceedences are also qualified on all associated sample results. Note:This flag is not applicable for matrix spike recoveries when the sample concentration is greater than 4x the spike added or for batch duplicate RPD when the sample concentrations are less than 5x the RL.(Metals only.) R Analytical results are from sample re-analysis. RE Analytical results are from sample re-extraction. S Analytical results are from modified screening analysis. J Estimated value.The Target analyte concentration is below the quantitation limit(RL),but above the Method Detection Limit (MDL)or Estimated Detection Limit(EDL)for SPME-related analyses.This represents an estimated concentration for Tentatively Identified Compounds(TICS). ND Not detected at the method detection limit(MDL)for the sample,or estimated detection limit(EDL)for SPME-related analyses.

Many of the byproducts of the gas production, such as coal tar(oily waste containing volatile and non-volatile chemicals),sludges,oils and other compounds are potentially hazardous to human health and the environment.The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly,serving as a continuous source of soil and groundwater contamination.

Select a graph, then type "Q" to exit graph menu. Appendix H Inputs Results Parameter Definitions --------------------- 1. Fraction of land in turf - refers to area maintaned as lawn, must be between 0 and 1. 2 . Fraction of land which is impervious - sum of roof area, driveways and roads; must be between 0 and 1. The fraction of land in natural vegetation is computed as 1 minus the sum of fraction in turf and the fraction impervious, thus the sum of these 2 must be less than 1. 3 . Average persons per dwelling - the average number of people living in each house or dwelling unit. 4 . Housing density - the number of dwelling units per acre. 5. Precipitation rate - the annual average precipitation in inches. 6. Water recharged from turf - the amount of water per unit area of turf which drains to groundwater. This can be computed from a water budget for the root zone. A 1-2-3 spreadsheet is available for this. [1] 7. Water recharged from natural land - the amount of water per unit area of natural of natural vegetation which drains to groundwater. This can be computed from a water budget. 8. Evaporation from impervious surface - the fraction of precipitation falling on impervious surface assumed to evaporate. Try 0.10. [1] 9. Runoff from impervious recharged - The fraction of the runoff which is recharged through recharge basins, ponds etc. Evaporation is subtracted. Use 0 here if storm sewers drain all runoff to surface waters. 10. Water use per person - average in-home use of water. Try 44 gallons per person per day. [2] 11. Nitrogen concentration in precipitation - average concentration, Use data from closest weather station where nitrogen tests were done. 12 . Nitrogen concentration in water used - average concentration in water used in homes. 13 . Turf fertilization rate - average yearly nitrogen application rate expected for residential turf. 14 . Fraction of nitrogen leached from turf - the fraction of nitrogen applied from fertilizer, precipitation etc. which leaches to groundwater. For sandy soil try 0.35 if clippings are removed, or try 0.5 if clippings are left on turf. These values are based on Long Island studies [3] , [4] . For tighter soils the fraction leached will probably be less. 15. Fraction of Wastewater N lost as gas - fraction of nitrogen in wastewater which volatilizes or is converted to gaseous N through denitrification. Roughly 0.50 under Long Island, N.Y. conditions. [5] This value is dependent on temperature and soil. Warmer areas will probably have higher fractions volatilized as will areas with tighter soils. Colder areas will probably have lower fractions. Vary this widely in your sensitivity analysis. (Perhaps 0.2 to 0.8) 16. Fraction of wastewater removed by sewer - efficiency of sewer. Try 0.90 which is to assume that 10% exfiltrates from sewers. If no sewers are present use 0. [4] 17. Nitrogen per person in wastewater - the average in the U.S. is 10 lbs/person/day. [2] 18. Nitrogen removal rate of natural land - the fraction of nitrogen in precipitation which is removed by natural land before the water is recharged. Should be at least 90 percent. Try 95 percent for forested areas. BIBLIOGRAPHY Appendix H Inputs Results ------------ [1] Mather, John R. 1979. The Influence of Land-Use Change on Water Resources.

Grosser Consulting 630 Johnson Avenue- Suite#7 Bohemia,NY 11716 RE: Evaluation of Viticulture Practices and Pesticide Use on Mazzoni Subdivision- SCTM#1000-13-2-8.2 Dear Mr. Rodriguez, We are pleased to provide the following to P.W. Grosser Consulting in response to the Town of Southold's comments dated February 10, 2017, and specifically comment (4) regarding the existing vineyard's general practices and pesticide use within 100 feet of the proposed drinking water wells of the residential subdivision. This evaluation is based on the list of pesticides and application dates reportedly applied between 2014 through 2016 as provided by the vineyard managers on March 6,2017.An assessment of each pesticide's purpose (insect, weed or fungus control), environmental index quotient (EIQ), leachability rating,and general toxicity statements is provided herewith. The EIQ provides an excellent tool to evaluate the pesticide leaching and potential for impact to groundwater. The applicants will utilize an Integrated Pest Management (IPM) program consistent with viticulture management guidelines for groundwater protection. The IPM programs for agriculture include: Soil Management Nutrition Management Vineyard Management Irrigation Management Weed Management Pest Management Pesticide Management Continuing Education Each of the aforementioned items are "integrated" and used to develop protocols in response to pest pressures. The IPM program utilizes cultivation techniques as its primary response to minimize and or avoid damage caused by disease pathogens and insects. The IPM program includes monitoring environmental conditions, scouting and daily monitoring to record conditions before a severe problem occurs.This includes trapping and identifying the insect pest, or diagnosing a fungus type,then setting a standard for what degree of crop damage is acceptable before a pesticide application is needed. PESTICIDE CONTROLS In the United States,the legal use of pesticides is controlled by the Federal Insecticide,Fungicide, and Rodenticide Act (FIFRA), enacted in 1947. The most significant amendment to FIFRA was the Federal Environmental Pesticide Control Act (FEPCA) of 1972. One significant part of the amendment required the USEPA to register all pesticides as well as each use of that pesticide and approve the product label. In summary the USEPA reviews all pesticides brought to market and either rejects or registers the pesticide for use. The pesticide label is required to provide product information as mandated by federal law. This labeling requirement is generally interpreted as, "the pesticide label is the law." Each pesticide label includes: • Product Name • Active Ingredients (by percent) • Inactive Ingredients (by percent) • Signal Words (Caution,Warning,Danger) • First Aid • Precautionary Statements (hazards to humans, animals,aquatic environments,etc.) • Personnel Personal Equipment (PPE) • User Safety Requirements • Engineering Controls • User Safety Recommendations • Environmental Hazards • Directions for Use(Agricultural and Non-Agricultural) • Aerial Drift Advisory Information • Integrated Pest Management Statements • Target Organism Resistance Management • Mixing,Loading and Application Instructions • Application Rates and Application Sites and Timing • List of Target Organisms Controlled • Maximum Allowable Quantity of Active Ingredient Allowed per Application per Year. • Storage and Disposal There are three classifications for pesticides that are used to categorize toxicity and provide warning statements used to advise the applicator.The product's safe handling by the applicator is detailed on each pesticide label.The label is required to provide"signal words"that advise applicators of potential concerns. • Class I "Caution" mildly toxic • Class 11 "Warning" moderately toxic • Class III "Danger/Poison" (skull and cross bones) highly toxic All registered pesticide labels state,"Keep-Out of Reach of Children." Personal Protective Equipment(PPE)generally required for each classification: Class I: Wear work clothes including long pants,long sleeve shirt,socks, and shoes. Class II: Wear coveralls over your work clothes or wear chemical resistant overalls. Class III: Wear chemical resistant overalls,chemical resistant boots and gloves. If the chemical is an eye irritant applicators wear eye protection. The applicator makes the final decision on what PPE is necessary based on the statements provided on the product label. Every pesticide label is reviewed for its specific personal safety requirements based on its specific toxicity rating. For vineyards, the majority of pesticide applications are fungicides,which generally are listed as Class I and II. The USEPA is also responsible for the administering the national program that assures a desired level of technical competence associated with private and commercial pesticide applicators. In New York State, the lead agency designated for pesticide registration, pesticide use, applicator certification and enforcement of state and federal regulations is the NYSDEC, Division of Materials Management Bureau of Pesticides Management.Commercial pesticide applications can only be performed by a NYS Certified Commercial Pesticide Applicator. Only specific pesticides are registered for use in Suffolk County by the New York State Department of Environmental Conservation. Applicators must hold a valid pesticide applicator license which involves the following: • Qualify as a Commercial Technician-Minimum age of 17;Completion of 30-hour NYSDEC approved training program. • Pass Core Exam— 90 minutes 50 questions-closed book • Pass Technical Exam- 90 minutes 50 questions-open book • Provide Proof of One-year experience with pesticide applications performed under supervision of a NYS Certified Commercial Applicator • Complete 12 hours of category specific certification training credits from pesticide courses approved by the NYSDEC • Pay NYS Certification fees NYSDEC regulates pesticide applications pursuant to 6NYCRR Part 325 Rules and Regulations Relating to the Application of Pesticides. Part 325.16 describes twelve categories of commercial pesticide applications. On-site staff involved in the application of pesticides shall at a minimum be a NYS Certified Commercial Pesticide Applicator. The NYSDEC also registers pesticides for use in the state, such that all USEPA registered pesticides are not legally permitted for use in New York unless the product is also registered by the state.The NYSDEC further restricts pesticide use within specific counties,with Nassau and Suffolk Counties having the most restrictions on pesticides available for use and limitations of annual cumulative application quantities for specific pesticides. Pesticides are available in several different formulations.These include aerosols,granules,ready- to use (RTU), emulsified concentrates (EC), wettable powders (WP), soluble powders (SP), flowables and fumigants. Controlling drift is important for the commercial applicator. The pesticide's formulation together with selection of pesticide application equipment can be effective in reducing the potential for drift. For example a pesticide as an aerosol formulation would have a greater potential for aerial drift than that same pesticide in a large particle granule formulation. With regard to equipment, an accurately calibrated drop spreader would apply a pesticide in a more precise location than a broadcast spreader; yet each would have less potential for aerial drift than the same pesticide applied from a helicopter. To be effective, the pesticide must be applied precisely on the target at the correct rate, volume and pressure. Particle drift can be influenced by particle size, nozzle design and orientation, pressure, temperature, humidity, evaporation, height of release, air velocity and movement, and each must be considered. To avoid aerial drift,and mitigate the potential for the spread of pollutants to sites outside of the project area, the applicator shall be required to follow the pesticide label. Typical label instructions are: • Use the largest particle and droplet size • Use the lowest practical pressure • Select nozzles that produce large numbers of large particles • Apply as close as practical to the target • Use a drift control additive(aka"stickers") • Not apply when wind,temperature or humidity are unfavorable • Choose non-volatile pesticide formulations • Increase flow rates of the application • Establish buffer zones to avoid ecologically sensitive areas and waterways • Use new technologies including:drift reduction nozzles,spray shields-boom curtains,air- assist spray and GPS area control equipment. The vineyard facilities will be equipped with PPE, OSHA required MSDS and employee hazard communication programs, emergency response and spill cleanup kits, trained personnel, wash down areas. Periodically pesticides are factored into the IPM program with selection and applications based on the site specific conditions. Progressive IPMs depend on a hierarchy of solving pest problems. The IPM establishes thresholds for pest tolerances insect counts from traps, weed counts, and disease impacts by measuring the area of damage. Pest problems can often indicate other agronomic issues that, once corrected can reverse the problems. For example, annual broadleaf weeds often invade areas where soils are compacted, turf has been removed and where drainage is poor. Improving the soil compaction by tillage, adding soil amendments with organic matter, and providing supplemental irrigation will reduce annual weeds to within threshold limits. The cultural practices would minimize or eliminate the need for treating weeds with herbicides. ENVIRONMENTAL INDEX QUOTIENT The Environmental Impact Quotient(EIQ)was developed to rate the risk of pesticides to human health and non-target organisms.The EIQ value is derived from mathematically weighting all the risk factors into a quotient. The EIQ is multiplied by the rate of application and percent active ingredient(%AI)to calculate the Field Use EIQ Rating(FUEIQ): FUEIQ=EIQ x Rate(lbs./acre)x%Al The FUEIQ provides a measure of the weighted risk or toxicity of a pesticide expressed as a value per acre.Multiplying the FUEIQ by the number of acres treated provides a risk/toxicity rating for the treated area. Summarizing all applications in this manner provides a summation of risks/toxicity for the entire property over a period. Cornell provides an online EIQ calculator to compare FUEIQ results (http://www.nysipm.cornell.edu/EIQCale/input.php). A FUEIQ under 25 is desirable.Any value over 100 poses high risks to applicators and the environment. Cornell lists the range of EIAs for each pesticide registered for use in New York. The Total EIQ is the combined weighted values for Farm Worker EIQ plus Consumer EIQ plus Ecological EIQ. The Total EIQ is shown below and the Leaching EIQ is the assigned value for leachability.

The mobility of these pesticides is restricted to the root zone. Among the list of pesticides applied,only Acephate moves readily in soil with water giving it the potential to contaminate ground water. However,because of its rapid degradation in soil it is not expected that it would exist long enough in the soil to have enough time to move into the ground water. It is because soil microorganisms rapidly degrade acephate under both aerobic and anaerobic conditions. Acephate's rapid degradation makes it non-threatening to groundwater or surface water.1 Bifenthrin is an insecticide that has low potential for leaching due to its low mobility in soil. Glyphosate is a non-selective herbicide (Round-Up)which is rapidly absorbed by the plant root and leaf with low soil mobility. It has a low potential for leaching. 1 Elizabeth Downing Environmental Monitoring and Pest Management Department of Pesticide Regulation Sacramento,CA 95814-3510 Mancozeb manganese, zinc, and ethylenebisdithiocarbamate ion is a fungicide and has a low mobility in soils. It is not a product with a high risk of leaching. Sulphur is a fungicide which does not leach below the root zone and has a low potential for leaching to groundwater. Boscalid and pyraclostrobin are combined chemistries as a fungicide that has low soil mobility and is not a risk to groundwater. The product is persistent and to protect aquatic organisms should not be applied in close proximity to the open water pond depicted on the Young&z Young subdivision map (dated Nov. 30, 2016).Typically it is recommended to keep a distance of 25-feet from open water when applications are made. Phosphite is used as a fungicide and is not a leaching risk to groundwater. Mandipropamid and difenconazole is a combined chemistry for use as a fungicide and was determined by the NYSDEC to pose no threats to ground and surface waters. Iprodione is a fungicide and has a low leaching potential because of its low mobility in soil. Fenhexamid is a fungicide with low leaching potential and is not a risk to groundwater. CONCLUSIONS The pesticides that have historically been applied at the subject site have a low potential for leaching largely due to low mobility in soil. Acephate is an exception to the soil mobility but studies show the soil microbes degrade acephate rapidly and therefore its persistence in the soil is low and groundwater leaching potential is not a concern. Based upon the proposed location of the potable on site wells,the influence that pesticides applied within 100-feet of the well field will have on groundwater quality is negligible.
