Construction of an on-site STP will require the approval of this Engineering Report and subsequent construction plans and specifications by the Suffolk County Department of Health Services (SCDHS). Construction of an on-site plant will not require variances from the Suffolk County Board of Review. The proposed location of an on-site STP with a 100 percent expansion area will comply with the minimum setback distances to the existing property lines and habitable structures. The closest STP would be Riverhead Sewage Treatment Plant and is located approximately 18.3 miles away from the site so it not feasible to service the proposed facility. The preliminary cost estimate to construct an on-site STP is $842,160 or about $88 per gallon of capacity. This includes the cost of the on-site sewage collection system, remote pump station, remote control building, BESST sewage treatment system and effluent disposal systems, engineering, legal and contingencies. 2.0 INTRODUCTION This report has been prepared to provide a preliminary design for the necessary construction of a new AVG facility designed to meet current SCDHS nitrogen limits for discharge to the ground water so the STP discharge will be in compliance with the effluent limitations included in the State Pollution Discharge Elimination System (SPDES) permit which would be issued for the STP discharge. This report describes the proposed sewage disposal requirements of the new AVG Facilities to be built on the north side of Main Road in Southold, Town of Southold, Suffolk County, New York. The proposed community will consist of a two- story restaurant with 80 seats, (44) forty-four hotel units with 88 seats restaurant for hotel guests only, a one-story future event space with 100 seats, and a pool area. The site currently consists of one lot and the Suffolk County Tax Map Number for the lot is 1000-63-3-15. The total gross area of the site is 6.75 acres. Based on the current SCDHS standards for sanitary design flows, the community will generate about 11,420 GPD of sewage. The site is located in the 600 GPD/acre Suffolk County Groundwater Management Zone IV. Based on net lot size of 6.75 (acres) the site can only discharge about 4,050 GPD of untreated wastewaters into the ground (600 GPD/acre x 6.75 acres = 4,050 GPD). Therefore, to develop the site as proposed, a STP must be constructed. The new STP would be designed and constructed to meet SCDHS standards. It is intended to use the provisions for a sub-surface STP such that the reduced setbacks can be achieved. The closest STP would be Riverhead Sewage Treatment Plant and is located approximately 18.3 miles away from the site so it not feasible to service the proposed facility. Since the off-site disposal option is not viable, it is proposed to build a new subsurface STP, at the AVG site. The proposed design would comply with the SCDHS, New York State Department of Environmental Conservation (NYSDEC) and Ten States Standards. P.W. Grosser Consulting, Inc ¤ P.W. Grosser Consulting Engineer & Hydrogeologist, PC 1 630 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 Shelton, CT The proposed STP and below grade effluent disposal facilities will be constructed in the northeast corner of the community. The community STP will be provided with stand-by power facilities. The community will have a sanitary collection system that transports raw sewage to the proposed STP facility. The influent will drain to a 10 ft. pump station/wet well. Effluent from the pump station/wet will then be transported via force main. The pump station/wet well will provide a continuous source of flow to the STP throughout the day. A continuous flow of sewage will improve the treatment plant process by providing a continuous source of organic material for the micro-organisms to use for the synthesis of ammonia nitrogen to nitrates and a continuous source of organic carbon to covert nitrates to nitrogen gas. Final effluent from the treatment plant will be recharged on-site with an underground disposal system comprised of leaching pools. The new STP and dedicated STP expansion area will be sited on the AVG property at a location that does provide a minimum setback distance of 75 feet from STP to any existing or proposed habitable structure and 50 feet from STP to non-habitable structures. The dedicated STP expansion area is to be contiguous with the STP area and be set aside to provide for a future 100% expansion of the STP and disposal system. A buffer area of 50 feet will also be provided around the proposed STP and dedicated expansion area. The area is to be used exclusively for the STP appurtenances. The location of the proposed STP is shown on Appendix No. 2 Î Site Plan with the SCDHS set-back requirements. 3.0 LOCATION AND SITE CONDITIONS The AVG Facilities will be located on the north side of Main Road (Route 25) approximately 78.92 feet east of Locust Lane, in Southold, within the Town of Southold, Suffolk County, New York. The specific location is shown on Appendix No. 1 - Location Plan. The proposed community will consist of a two-story restaurant with 80 seats, (44) forty-four hotel units with 88 seats restaurant for hotel guests only, a one-story future event space with 100 seats, and a pool area. The site currently consists of one lot and the Suffolk County Tax Map Number for the lot is 1000-63-3-15. The total gross area of the site is 6.75 acres. The site is sloped and mostly undeveloped. The average surface elevation is about elevation 30 feet above mean sea level (AMSL). The site is located in Zone X (minimal flood hazard) per FEMA flood map. Proposed development of the site will include on-site subsurface storm water disposal systems to dispose of storm water run-off to below grade, precast-concrete, storm-water, drywells. P.W. Grosser Consulting, Inc ¤ P.W. Grosser Consulting Engineer & Hydrogeologist, PC 2 630 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 Shelton, CT 4.0 WASTEWATER CHARACTERISTICS The sanitary wastewater from AVG community is expected to be typical of normally found in other similar communities. The SCDHS generally has approved design of proposed treatment facilities assuming the wastewater characteristics: 5 day Biochemical Oxygen Demand BOD= 272 mg/L -5 Total Suspended Solids TSS = 320 mg/L Total Nitrogen as N TN-N = 65 mg/L Ammonia Nitrogen as N NH-N = 45 mg/L 3 The AVG STP will be designed to produce an effluent with less than 10 mg/L total nitrogen at the average and peak hourly flow rates. 5.0 DESCRIPTION ON-SITE SEWAGE TREATMENT AND DISPOSALS SYSTEM The process selected to treat the wastewaters is the Biologically Engineered Single Sludge Treatment (BESST). This process is a variation of the activated sludge process and will effectively remove BOD, TSS and nitrogen levels to comply 5 with the New York State Department of Environmental Conservation (NYSDEC) State Pollution Discharge Elimination System (SPDES) Permit. The BESST process is designed for five-day carbonaceous biochemical oxygen demand (BOD), ammonia nitrogen 5 nitrification and denitrification. In this process, ammonia nitrogen is oxidized to nitrite and then to nitrate by Nitrosomonas and Nitrobacter bacteria, respectively. The nitrate is then reduced by dissimilarity nitrate reduction. In this reaction, the incoming BOD serves as the carbon source or electron donor for the reduction of nitrate to elemental nitrogen. In the 5 process, fermentation of soluble BODoccurs in the anoxic zone. 5 The BESST process is a modified version of the Lawrence and McCarty biological process. This process introduces sewage into an anoxic section of the tank where the micro-organisms will use the endogenous carbon to perform denitrification. This stream is mixed with a stream of nitrified wastewater coming from nitrified return active sludge from the sludge blanket clarifier. Submersible mechanical mixers are installed in the anoxic compartment to facilitate homogenous mixing and increase the denitrification efficiency. Mixed liquor flows in a plug flow manner to the aeration zone where fine bubble diffusers provide the oxygen required for nitrification and BOD5 reduction. After aeration, the mixed liquor enters the bottom of an up-flow clarifier where solid and treated effluent is separated. Mixed liquor settles to the bottom and an air lift pump conveys RAS into the anoxic tank. A weir box at the top of up-flow clarifier allows treated effluent to go to the on-site groundwater disposal system. Sanitary wastewater from AVG community will flow by gravity to the STP via a new sewage collection system. Sewage will flow by force main and gravity into the new exterior influent pump station. Wastewater would be pumped via one (1) of two (2) submersible explosion proof, solids handling pumps to a self-cleaning, mechanical screen. The pumps will P.W. Grosser Consulting, Inc ¤ P.W. Grosser Consulting Engineer & Hydrogeologist, PC 3 630 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 Shelton, CT invoke a new technology called Ðadaptive impellersÑ. This new technology will prevent all non compressible solids from becoming clogged within the pump impeller without the necessity of utilizing grinders, shredder or cutter mechanical devices. The new mechanical screen will be located above grade on a concrete pad, near the proposed BESST system. Solids removed by the screen will be discharged by gravity into the screen trash bin. The perforated openings in which the influent wastewater will cascade over will require routine maintenance to prevent excess buildup of solids. The screened wastewater will flow by gravity to the new constant head / splitter box. This box controls the forward flow rate to the BESST treatment and the return flow rate to the influent pump station. The splitter box automatically splits the flow equally to the influent ends of the two (2) BEEST process tanks. Refer to Appendix No. 4 - Proposed On-Site Sewage Treatment Plant Hydraulic Profile and Appendix No. 5 -Floor Plan of On-Site Sewage Treatment Plant for the general layout and process piping for the proposed STP. The BESST STP will be comprised of dual train treatment process comprised of two (2) separate aeration/clarifier tank and anoxic tank sections. A pipe and slide gate will connect the two anoxic tanks such that mixing of the RAS will occur between the two anoxic tanks thus causing both trains to have an approximate equal amount of mixed liquor suspended solids in both tanks. This will optimize operational control of the process. The BESST STP is an easy treatment process to operate because there are no cycles within the process. This STP is a flow through process. Blowers are continuously energized to provide diffused air within the aeration and sludge holding tanks and to operate the air lift pumps to return nitrified activated sludge from the up-flow clarifier to the anoxic tanks. The STP operator will be required to manually open a sludge waste valve that will divert the RAS to the sludge holding tank. The sludge holding tank will continue to process the RAS. Periodically the sludge holding tank blower will be de-energized such that the digested sludge will be able to settle. A supernatant return pump located within the sludge holding tank will convey top water from the sludge holding tank back to the pump station. This will significantly reduce the cost to haul sludge off-site for additional processing and disposal. The SCDHS allows the BESST STP process to operate with three (3) blowers. One dedicated blower will be used for the aeration and the RAS air lift pumps. One blower is used exclusively for the aeration of the sludge holding tank. The third blower is used as a standby blower in the event either one of the other two blower is out of service. Periodically the aeration tank duty blower and the standby blower is alternated such that there will be equal run time on each blower. The blowers will be located within the control building and have a soundproof enclosure. A control building will be constructed for multiple purposes. The control building will provide the required space for a laboratory and bathroom. The building will also provide additional sound attenuation for the blowers. The odor control treatment system will be located outside of the control building. The control building will also permit STP electrical equipment to be located indoors and not exposed to the elements. A flow monitoring station will be installed upstream of the groundwater disposal system and downstream of the two (2) effluent pipes from the BESST process. P.W. Grosser Consulting, Inc ¤ P.W.

The leaching pools will be sized for long term disposal of effluent without the use of effluent filtration equipment. 6.0 DESCRIPTION OF ON-SITE SEWAGE COLLECTION SYSTEM The design of the required on-site sewage collection system will depend on the design of the plumbing facilities to serve the various units of the hotel community and a restaurant. It has been verified that the community will consist of a two-story restaurant with 80 seats, (44) forty-four hotel units with 88 seats restaurant for hotel guests only, a one-story future event space with 100 seats, and a pool area. The building plumbing system will have to be designed in compliance with the requirements of the SCDHS as well as the New York State Plumbing Code. The onsite sewage collection system will transport raw sewage via force main and gravity to the proposed influent pump station from the restaurant, hotel units, and cottages. An 1.25Ñ diameter force main would convey the sewage from the restaurant to the proposed manhole. An 8Ñ diameter DR-18 PVC gravity sewer would convey the sewage from the proposed manhole to the influent end of the pump station, entering the Influent Pump Station at elevation 19.30. Raw wastewater will then be pumped to the mechanical screen via force main. The onsite sewage collection system will consist of (1) one e-one pump station, three (3) 4-ft. diameter precast concrete manholes and two (2) 5-ft. diameter precast concrete manholes used at intersections, changes in direction and termination points. The total length of piping for the collection system is approximately 1,200 linear feet. 7.0 DESCRIPTION OF REQUIRED MONITORING WELLS To comply with SCDHS standards, two (2), 2Ñ diameter monitoring wells are required to be provided in the vicinity of the ground water disposal systems to permit quarterly monitoring of the effect the STP effluent has on ground water quality. The necessary new wells will consist of one (1), 2Ñ diameter monitoring wells properly sited down gradient of the leaching pool disposal system and one (1), 2Ñ diameter well located up gradient of the leaching pool disposal system. Review of available source of groundwater maps indicates groundwater at this site is flowing in an north-south direction. Each new well will include the installation of a 4Ñ diameter surface casing with lock, 2Ñ diameter PVC schedule 40, 15 feet long, 20 slot, screened well a minimum of 10 feet into ground water. The screen shall be installed 5 feet above and 10 feet below the prevailing ground water table. New wells will be installed in compliance with the most recent requirements of the SCDHS. Wells will be monitored quarterly for required water quality parameters included in the NYSDEC SPDES permit. All well construction would be performed by a New York State licensed well driller. The proposed number and location of monitoring wells is shown on Appendix No. 2 Î Site Plan. The installation of the monitoring wells will also include: 1. Meeting with the SCDHS to properly site the required monitoring wells based on the determined flow direction of ground water. 2. Retain the services of a licensed well driller to file for required permits. P.W. Grosser Consulting, Inc ¤ P.W.

Installation of monitoring wells at the location(s) approved by the SCDHS. 4. File completion logs with the NYSDEC and the SCDHS. 5. Initial bailing of wells and collection of water samples. 6. Provide well tags and casing keyed locks on all wells. 7. Locate and inspect all new monitoring wells and record the well number, the NYSDEC number, the well casing size, and height above finished grade. Verify the depth of water in each well and if samples can be properly obtained. 8.0 SETBACK DISTANCES As required by the SCDHS standards, a 100 % expansion area immediately adjacent to the STP should be provided. This area is for the construction of a replacement STP. The proposed site of the STP and the location of the 100 percent expansion area will comply with the setback standards of the SCHDS, namely 75 feet from STP to habitable structures and 50 ft from STP to the non-habitable structures setback lines. The proposed construction of the STP will comply with the setback requirements for residential dwellings surrounding the project area. 9.0 ODOR CONTROL TREATMENT SYSTEM Since the treatment system will be classified as a modified sub surface sewage treatment plant, an odor control treatment system will be installed for the process tanks and pump station. The odor control treatment system will be installed within the control building. The proposed ventilation system will utilize mechanical ventilation equipment to collect all air discharge twelve (12) air changes per hour within the STP. The basis of design for the ventilation system is as follows: 3 Wet Well / Equalization Volume: 1,676.83 ft 3 Sludge Holding Tank 5Óx 10Ó x 9.5Ó = 475 ft 3 Constant Head Splitter Box Above Water 2.5Ó x 4Ó x 2Ó = 20 ft 3 Total Volume 2,171.83 ft 33 Required cubic feet of air to be treated per hour = 2,171.83 ftx 12 (changes/hr.) = 26,061.96 ft/hr. 33 Require air volume = 26,061.96 ft/hr. / 60 min./hr. = 434.37 ft/min.

Nitrification is autotropic and all Purestream ES, LLC integrated bioreactors are designed for complete nitrification of ammonia to NO (please 3 see Metcalf & Eddy, Third Edition, Chapter 11-6). Denitrification, however, is heterotropic and requires a carbon source. Conventional plants' "separate sludge denitrification" requires that carbon is added, typically in the form of methanol. This adds to operating costs, and if used in excess, to increased BOD content. BESST technology's "single-sludge denitrification" 5 approach uses an endogenous carbon source to maintain dentrifiers. Influent is combined with nitrified mixed liquor in the anoxic compartment providing the carbon source needed for denitrification. Relatively high mixed liquor recycle rates are employed and sufficient denitrification retention times provided. Total nitrogen reduction (N) is a subject of not only providing sufficient anoxic volume for denitrification and T keeping temperature above a certain minimum, but also a function of Recycled Activated Sludge (RAS) flow rate. The efficiency of N reduction is expressed as follows: T = (1 - 1/(1 + n)) x 100 Where n = RAS flow multiple of average flow Q. The following are typical efficiencies and RAS flow multiples used / required: l (%) n Domestic 266 375 480 Slaughterhouse Wastewater 1493 Hog Manure 2997 3 Phosphorous Reduction BESST technology delivers not only high efficiency reduction of organic matter, but also increased efficiency of phosphorous removal. Two processes, biological and chemical precipitation are employed with advantage. The mechanics of biological phosphorous removal, known as "Luxury Uptake", are due to exposure of activated sludge to alternating oxic and anoxic conditions. Under these conditions, the cells store more energy in the form of phosphorous than needed for their survival. If strictly oxic conditions are maintained during subsequent clarification, phosphorous will be retained by the cells and will eventually be removed with the excess sludge. Unlike most other methods of clarification, these conditions are maintained by the BESST process, and biological phosphorous reduction to less than 3 mg/L are readily achievable. The basic reaction involved in the precipitation of phosphorous with iron is as follows: +3n-3+ Fe + H(PO) FePO + nH n44 In the case of iron, 1 mole will precipitate 1 mole of phosphate. The advantage of the process is its low chemical consumption, close to stoichiometric, and consequently, the reduction of ballast sludge production. Followed by microfiltration, reductions to 0.5 mg/L are possible. If yet further reduction of phosphorous is required, ferric sulfate precipitation after the bioreactor followed by microfiltration must be used. 4 BESST Sizing and Pricing Program v7.9.2004.01 P/E Job No.BJB-103123-TEDate10/31/23 Job NameThe Enclaves B0.12kg BOD/kg VSS d0.12Bx0.098441796 Nx6kg SS/m2h6A29.19360047 vl1m/h1kd0.024810995 Vx0.6ml/l0.6X6 KI100ml/g100Xv3.9 p0.65MLVSS/MLSS0.65v0.740818223 Y0.6kg-1 VSS/kg BOD0.6VB39.41 kac0.09d-10.09Ss7.29 Flow 11,420GPD43.22483Vs10.57 Peak3QQ3Px5.26 BODin350mg/l0.35Pt8.10 BODout0mg/l0Vn23.49 NH3-Nin65mg/l0.065Vd23.05 NH3-Nout0mg/l0Va23.49 TNout0mg/l0Vt57.12 TSSin320mg/l0.32O232.87 TSSout0mg/l0Nm113.90 T min10C10uc100.00% T max20C20 20 0.69 1.37 7 0.1 1.3 Material Copyright z 2003 Michael G.
