INTRODUCTION The Town of Southold authorized the firm of Holzmacher, McLendon & Murrell, P.C. (HM&M) to conduct a study and prepare a Solid Waste Management Plan and detailed report for the Town's existing solid waste disposal facility in accordance with the New York State Department of Environmental Conservation (NYSDEC) Rules and Regulations, Part 360. The purpose of this study is to meet the follow-up requirements on the preliminary application for approval to operate a solid waste management facility which was submitted to the NYSDEC in February 1978. REPORT SCOPE The scope of this study includes: 1. Evaluation of existing operation conditions of the Town's landfill and to make recommendations regard- ing improvements of landfill operation in order to comply with Part 360 Regulations. 2. Short and long-term solid waste disposal alternatives. 3. Future utilization of the completed site. The scope is generally in accordance with the NYSDEC's "Content Guidelines for Plans and Specifications" as they apply to an existing solid waste management facility such as the Town of Southold. 1.

SUMMARY OF FINDINGS AND CONCLUSIONS _____.~__~.___~_......___ ...,_.._.__.n______.__ This Solid Waste Management Plan and Report, pr~pared for the Town of Southold as a part of regulatory requirements of the NYSDEC, NYCRR Part 360, contains the following information: 1. The Town of Southold comprises approximately 53 square miles and presently has 20,022 permanent inhabitants. The popu- lation for the year 2000 is projected at 33,630. 2. The existing sanitary landfill located on North Road, east of Depot Lane in the north-west section of the Town of Sout- hold, currently receives 34,000 tons per year of municipal solid waste and demolition waste. The entire Town with the exception of Fishers Island is served by this landfill facility. Per capita waste generation by the permanent population is estimated at 6.9 pounds per day. The projected waste generation for the year 2000 is 60,420 tons. 3. Approximately 1,130,000 gallons of scavenger waste, mainly liquid pumpings of cesspools and leaching systems, was received and disposed of at the landfill during 1978. 4. At the projected rate of solid waste deposited in the landfill, the 41 acre site will reach its volumetric capacity by the beginning of 1985. 5. A 201 Wastewater Management Facilities Plan is underway for the Town of Southold/lnc. Village of Greenport. Incorporated within this report will be an 0valuation of alternative methods for treatment and disposal of Southold's scavenger waste. A selected plan and implementation will follow. 6. The existing site does not have a groundwater monitoring system. Data obtained from groundwater monitoring and public 2. I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P,C. I H2M CORP. supply wells in the vicinity of the landfill do not indicate the presence of leachate. 7. The existing landfill is not provided with a conventional leachate collection or treatment system. Existence of adequate amounts of fine soil underneath the landfill have presumably mini- mized leachate migration by natural attenuation. To date, no complaints from the neighboring landowners regarding methane migra- tion or vegetation kills have been registered by the Town. 8. An evaluation of the existing operations at the Southold sanitary landfill shows that most of the landfill operations are carried out in an environmentally acceptable manner, and in accor- dance with the State guidelines. Solid wastes are properly spread, compacted and covered with on-site available cover material. Site facilities and access roads are maintained on a regular basis. Re- commendations have been made to reduce the problem of blowing litter and debris. 9. At this writing, the existing equipment at the landfill is inadequate. The Town, however, is in the process of acquiring State funds for new landfill equipment. 10. Pending the approval of NYSDEC of the application for a permit to operate a solid waste management facility; the Town will continue sanitary landfilling in the immediate (present to one year), and the intermediate (one to six years) future. However, during this period, it is recommended tha t the Town evaluate long range alternatives, including resource recovery and applicable State and/or Federal financial assistance. Several long range 3. I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. future options are available to the Town such as straight sani- tary landfilling (if landfilling is permitted by NYSDEC), modular incineration with energy recovery, transfer haul to Brookhaven's proposed resource recovery facility and composting (of refuse alone or co-disposal of reluse and sewage sludge). 11. Development of solid waste disposal ordinance to control refuse management is recommended. 12. Immediate installation of a three well groundwater moni- toring system and periodic check of methane gas migration at the Southold landfill is recommended. 13. Several future site utilization vians for the completed landfill have been delineated. It is recommended that the Town consider these plans and explore potential funding sources for implementation. 4. I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENOON and MURRELL, P.C.

EXISTING CONDITIONS Study Area The Town of Southold, located on the eastern portion of Long Island, Suffolk County, New York, is comprised of a total of twelve communities of which eleven are unincorporated and the Inc. Village of Greenport. The study area comprises approximately 53 square miles. Figure 1-1 is a location map of the study area. The Town is presently serviced by one sanitary landfill located on North Road between Depot Lane and Cox Lane. 1.0 1.1 1. 2 Population 1.2.1 Permanent Population For the purposes of this report we have used the population projections as adopted by the Nassau-Suffolk Regional Planning Board (NSRPB) in the November 1976 208 Wastewater Management Study. The same projections have also been used by the Long Island Light- ing Company (LILCO) for their planning purposes. The census enumerated in 1970 showed 16,804 permanent resi- dents in the Town of Southo1d. The population increased at an average rate of 166 persons per year during the period 1950-1960. The rate of increase between 1960 and 1970 was 351 persons per year. The 1979 LILCO population estimate for the Town is 20,022, amounting to an increase of 357 persons per year between 1970 and 1979. The 1995 estimate is 29,972. The NSRPB carried their projections through 1995 only. However, based on the projected trend as a percentage of the saturation population of 72,921 for 1.1 I I I I I I I I I I I I I I I I I I I FIGURE N2 I-I NEW '-...- " /' ~ CONNECTlC UT NEW JERSEY \ ...\ E~ . _ .. . o \ \..IloOR ,'......'I;~...:.',:.

The current population and the projec- tions in five year increments are shown in Tables 1-1 and 1-2, respectively. 1.2.2 Seasonal Population During summer months, the population of the Town of Southold increases substantially due to arrival of residents of summer homes, tourists and vactioners. Determination of the seasonal increase in population is essential in order to compute the yearly solid waste quantities brought to the Town landfill. The NSRPB 208 Study listed the number of homes with summer occu- pants which was utilized for estimating the seasonal population. In addition, the Village of Greenport water supply pumpage re- cords were utilized to establish the number of tourists and vaca- tioners, and the monthly distribution of the entire seasonal population. Table 1-3 shows the monthly breakdown of population under various categories. 1.3 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENOON and MURRELL. P,C. / H2M CORP.

SOLID WASTE COMPOSITION AND QUANTITIES Solid Waste Composition Because of variations in the use of materials throughout the United States, the composition of solid waste differs from muni- cipality to municipality. Only by separating and weighing samples of refuse can waste composition be determined precisely for a particular locality. Such preciseness is not necessary for a study of this type and since exact data were not available for the study area, general compositional data have been obtained by examining figures for similar communities and for the nation as a whole. Table 2-1 indicates the primary components of various cate- gories comprising municipal refuse. Studies have been made to determine the percentage of the waste stream that falls into each of these categories. Table 2-2 shows the results of these studies. As shown, paper constitutes the major portion of muni- cipal refuse. The proportion of food wastes in municipal solid waste has been declining in recent years. This downward trend will prob- ably continue as the use of preprocessed, frozen and packaged foods expands. Home garbage disposal units also help decrease the amount of food wastes entering the municipal solid waste stream. Glass and metal wastes will probably increase if the present popularity of non-returnable liquid containers persists without regulation. The composition of municipal refuse also varies by the time of the year as presented in Table 2-3. 2.0 2.1 2.1 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP.

A solid waste survey of all refuse haul- ing vehieles entering the landfill site was conducted by HM&M on April 17, 1979. By estimating the quantities carried by each vehicle, the total quantity of waste entering the landfill was calculated as shown on Table 2-4. These results were confirmed by a simJ.lar survey previously conducted by the Town on March 28, 1979. Extensive discussions with the landfill offi- cials were held to determine various characteristics of the waste generated within Southold. Through these communications it was learned that on an annual basis, approximately 12 tons per day of agricultural waste (potato culls) are disposed of at the land- fill. Also the brush, leaves and wood quantities increase suffi- ciently during the early spring and fall seasons due to a clean-up program initiated by the Town. Using this information, municipal solid waste (MSW) genera- tion rate by permanent population was estimated, which was then utilized for computing MSW generated by the seasonal population (summer vacationers) during the period April through September. Finally, the total quantity of solid waste received at the land- fill for the year 1978 was determined by summing up the MSW gen- erated by permanent and seasonal population, demolition waste, potato waste and brush. Table 2-5 shows a monthly breakdown of these quantities. On a daily basis, it is estimated that the 2.5 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENOON and MURRELL, P.C. I H2M CORP.

The 1978 breakdown by category of the total solid waste re- ceived is as follows: Permanent Population 24,800 tons Seasonal Population 3,800 tons Potato Waste 4,400 tons Extra Brush 1,000 tons TOTAL 34,000 tons 2.2.2 Per Capita Waste Generation Utilizing the data obtained through the solid waste survey, characteristics stated in conversations with landfill officials, and the average daily quantity of waste generated by the perman- ent population of 19,601 excluding Fishers Island popula- tion, the actual per capita waste generation is computed as 6.9 pounds per day. Disposal of solid waste generated by 421 persons in Fishers Island is reportedly carried out within the Island boundaries. Based on 6.9 pounds per capita per day, the waste quantity for Fishers Island is estimated at approximately 1.5 tons per day. The per capita generation rate is generally higher than the national and regional averages of per capita refuse gen- eration. This can be attributed to several factors including excessive amounts of brush and agricultural waste brought into the landfill throughout the year and perhaps disposal by non-resi- dents. However it should be emphasized that the per capita 2.8 I I I I I I I I I I I I I I I I I I I HOLZMACHER. McLENDON and MURRELL. P.C. I H2M CORP. generation rate is based on the estimated quantities of solid waste received at the landfill. A precise determination can only be made by weighing and identifying all incoming waste. 2.2.3 Projected Waste Generation The projected solid waste generation for the Town of Southold through the year 2000 is presented on Table 2-6. Using 1978 as the base year, the per capita solid waste generation rate of 6.9 lbs. was escalated at one percent per year on a linear basis. Using the population projections presented in Section 1.0 (Table 1-2), solid waste quantities generated by the Town's permanent popula- tion were computed. To these were added the waste quantities produced by seasonal population, potato waste and extra brush to arrive at the total waste quantities requiring disposal, ex- clusive of Fishers Island. These quantities are data utilized to calculate the remaining life of the Town's existing landfill. Quantities for Fishers Island are projected separately. The last column of Table 2-6 shows the total solid waste quantities to be disposed of for the Town of Southold. These projections are graphically illustrated in Figure 2-1. 2.9 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP.

The private haulers directly charge the residents for the collection and haul of their waste to the Town landfill. At this wri ting, there are no dumping c harges at the landfi 11. Approxi- mately 60 percent of the total waste is collected privately and the remaining is brought in individual cars and small pick-ups. In the Town of Southold, solid waste operations are adminis- tered through the Department of Public Works. The Superintendent of Public Works is in charge of the disposal facility operations and personnel. Also, for the Town of Southold, the Superintendent of Public Works holds the position of Superintendent of Highways. This dual-departmental relationship is both advantageous and disadvantageous in the operation of each department. The existing budget allocated to the landfill operations is not sufficient to cover proper operation of the facility and main- tenance of the equ ipmen t. When a vai la ble, the highway equ ipmen t are reportedly brought into the landfill to supplement the exist- ing landfill equipment. This method on one hand, does allow con- tinuous operations of the landfill in an environmentally acceptable manner, but on the other hand puts a heavy burden on the highway equipment availability, maintenance and repairs. 3.1 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENOON and MURRELL. P.C. / H2M CORP. Currently there are no dumping fees for solid waste disposal at the Town landfill facility. This system is believed to have several drawbacks when compared to a system of operating the fac- ility with an imposed disposal fee. These include: 1. Surround ing townships impose disposal fees at their landfill facilities. Therefore, with Southold not charging dumping fees, it is conceivable that some "out of town" refuse may be brought into the Southold landfill. This not only results in the handling of additional quantity of refuse being deposited in the landfill, but also decreases the potential life of the facility. 2. Presently, the Southold landfill facility does not enforce a residency requirement, as do other town- ships within the surrounding area. This again may encourage "out of town" refuse disposal at the site. 3. Potential revenues, which could help offset the cost of landfill operations, are lost by not imposing a dumping fee. Currently the Town Board is in the process of organizing a "proof of residency" program. This will require all resi- dents of Southold to obtain a car sticker to indicate residency and prevent non-residents from utilizing the disposal site. This report will recommend that the Town consider institut- ing a dumping fee on private collectors who bring waste to the town landfill. This will be discussed further in Section 9.0. 3.2 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. In addition to solid waste, the Southold landfill also ac- cepts scavenger waste. As in the case of solid waste, there are no dumping charges for disposal of scavenger waste at the site. The NYSDEC and the Town of Southold have agreed on a compliance schedule to abate this practice. 3.2 Disposal Sanitary landfilling is the only method of solid waste dis- posal in the Town of Southold. The Town landfill is located on North Road between Cox and Depot Lanes in Cutchogue (see Figure 3-1). The existing site consists of approximately 41 acres and has been the designated area for solid waste disposal under Town supervision since 1954. It was reported that unsupervised dis- posal of refuse at this site took place even before 1954. The landfill procedures consist of the trench fill method in which solid waste is placed in excavated trenches and the excavated earth, mainly fine sand and gravel occasionally mixed with clay, is used for cover material. Excess quantity of excavated mate- rial is both sold to a private contractor and utilized by the Town's Highway Department. Due to adequate supply of on-site cover material, all wastes are properly covered at the end of the day's operation. Scavenger waste is discharged into separate settling lagoons situated at the northwest corner of the landfill. The landfill facility remains open between 7:30 A.M. and 5:00 P.M., all year-round except on four legal holidays designated by the Town as listed below: 1. Christmas Day 2. New Year's Day 3. Easter Sunday Thanksgiving Day 4. 3.3 I I I I I I I I I I I I I I I I I I II FIGURE N!! 3-1 ", 0'(4.\(;. ... ,0'" vt'O 50 //~ ~~O \5~ ./ / ./ ~ I \ ~,,<> ,,>" SOUTHOLD LANDFILL SITE O~G ~ , \ . \ \ 8~i LOCATION PLAN ~\c .

The operating personnel normally consists of four full-time persons plus one CETA (Comprehensive Employment and Training Act) worker. A rotating schedule is used so that each full-time employee works a four day, 40 hour week, with at least two Town employees at the site during operating hours. The CETA worker is employed by the County and placed under the supervision of the Town's Department of Public Works. The CETA worker will re- main with the Town so long as the County funds are available. A typical personnel assignment schedule is depicted in Figure 3-2. The existing equipment at the Southold landfill facility con- sists of a front-end loader with the following features: 1. Allis-Chalmers - Model AC-llOOO, rubber tired. Hours of Operation (as of 5/79): 9,000 hours. Year of Purchase: 1972. Rebuilt Motor. Bucket: 4 cubic yards, general purpose. Additionally, a portable conveyor equipment is also available at the site for the purposes of loading the excavated sand unto trucks. The Highway Department's trucks are utilized for on-site transporting and stockpiling cover material for landfill opera- tions. The front-end loader is utilized for excavating sand and spreading, compacting and covering of solid waste. At the time of preparing this report, the front-end loader was out of service, in need of repairs. The Town Highway Depart- ment front-end loader is at the site performing the landfill operations. The Town is currently in the process of acquiring State funds, under Environmental Quality Bond Act of 1972, for 3.5 I I I I I I I I I I I I I I I I I I I FIGURE N2 3 - 2 1st WEEK 2nd WEEK M T W T F S S M T W T F S S EMPLOYEE #1 EMPLOYEE #2 EMPLOYEE #3 - EMPLOYEE #4 CET A EMPLOYEE NOTES: (1) Daily Operating Hours are 7:30 A.M. to 5:00 P.M.

Equipment needs at the landfill are discussed later in this report. 3.2.1 Existing Disposal Costs The following is the 1978 breakdown of the expenses for the operation of the Southold sanitary landfill, as reported by the Town officials: Personnel Services (Labor plus Benefits) $ 59,000. Contractual Services (Includes lights, power, contractual repairs of equipment, materials and supplies) 18,000. TOTAL 1978 BUDGET $ 77,000. Town of Southold does not have a separate budget for its sani- tary landfill facility. All capital and operating expenses are appropriated from the General Funds Account as approved by the Town Board. 3.2.2 Unit Costs of Disposal Based on the above cost of landfill operations, and 1978 quantities of solid waste received at the landfill (34,000 tons), the unit cost of disposal is computed as $2.26 per ton. 3.3 Landfill Site Life The useful life of a sanitary landfill is a function of several parameters such as the rate at which solid wastes are deposited, the in-place compaction density, the cover material requirements, and the volumetric capacity of the site. To 3.7 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. calculate the remaining life of the Southold landfill, we have established these parameters as follows: 1. Rate of solid waste deposited: 34,000 tons for 1978, and according to Table 2-6, Column 5, thereafter. 2. In-place compaction density: 600 Ibs.jcubic yard.(a) 3. Ratio of refuse to cover material, by volume: 4:1. The volumetric capacity is determined by establishing the final grade and the depth of fill for various sections of the site. These sections are shown in Figure 3-3. A large scale site plan showing the existing contours and the site facilities is included in Appendix A of this report. In accordance with the NYSDEC Regulations for Mining Operations and Sanitary Land- fill a number of design criteria have been used to arrive at the fill volume available for each of these sub-areas. They include: 1. The fill areas terminate at a minimum of 50 feet from the property-line. 2. Side slopes of the excavated areas are at 300 to the horizontal. 3. The existing elevations are as of April 1979. 4. The final grade of the filled areas is brought to the original contours (prior to any excavation). Of the total 41 acres at the Southold landfill site, approxi- mately 12 acres are completed to the final grade. The areas lost due to the 50 foot margin, slope of excavation, scavenger waste (a) This is assumed to be the most practicable density achievable at the Town landfill under the existing operating conditions. 3.8 I I I I I I I I I I I I I I I I I I I TOTAL AREA OF 41 ACRES LANDFILL SCAVENGER WASTE DISPOSAL LAGOONS F- I CD @ EXISTING DISPOSAL AREA COMPLETED AREA 50'-ldr: PROPERTY LINE @ .-- ENTRANCE AND BUFFER ,~- -:- - t/I\OOL.E RO~O tc.R 2:71 AREA ACREAGE 2 2 6 3 8 * AS OF APRIL 1979 SITE LIFE DETERMINATION OF SOUTHOLD LANDFILL FIGURE Nil 3 - 3 FUTURE LANDFILL AREA FUTURE MINING AND LANDFILL I AREA J - AVAILABLE VOLUMETRIC CAPACITY (AC.-FTJ* 30 210 317 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT PLAN AND REPORT JUNE 1979 HOLZMACHER, McLENDON & MURRELL, P.C.

Thus, the remaining area available for existing and future landfill operations is approximately 16 acres which is further divided into three sub-areas. Based on the information portrayed in Figure 3-3, the volumetric capacity of the sub-areas as of April 1979 is com- puted and presen ted in Table 3-1. The .total remain ing capaci ty of the landfill site is computed as 898,600 cubic yards. Yearly landfill volume depletion calculations beginning April I, 1979 are presented in Table 3-2. These calculations are based on the aforementioned parameters for the projected waste quantities deposited in the landfill, the in-place com- paction densities and the cover material requirements. The landfill volume depletion is graphically illustrated in Figure 3-4. It can be seen that the entire site volume of 898,600 cubic yards will be exhausted by the beginning of the year 1985. Thus, the life of the Southold landfill site calculated as of April 1979 is 5.75 years. 3.4 Scavenger Waste Disposal Scavenger wastes are the liquid pumpings of cesspools, leach- ing systems that failed to operate properly. The general nature of the leaching systems causes ultimate failure. The typical residential system has an average life of 8 to 12 years. Commer- cial establismnents and restaurants require more frequent pumping. A leaching system fails due to various causes such as high ground- water conditions, poor soil characteristics for leaching, 3.10 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURREll, P.C.

Failures are noticed by owners when backups occur and liquids cannot enter the leach- ing system. Once failure has occurred, the leaching system is pumped bY scavenger trucks and the waste disposed of at the sani- tary landfill facility. Usually, the frequency of pumping in- creases after the first failure. Recent legislation by Suffolk County to eliminate the sale of detergents, so not to degrade the groundwater quality, has caused a return to the use of soap. This material coats and clogs soil pores and has caused a notice- able decrease in the life of cesspool-leaching systems. Sources of scavenger wastes include residences, restaurants, commercial establishments, industries, laundromats and sewage pump-out facilities. Sewage pump-out facilities are located at marinas and docks in order to aid boats in disposing of their wastes. At the present time, the scavenger waste is discharged into either of two uncovered 100 x 75 foot leaching lagoons located in the northwest corner of the Southold landfill site. A third lagoon was previously utilized, however, excessive usage and soil pore cloggage has necessitated the ~bandonment of this lagoon. The scavenger waste is received on a seven day a week basis in tank trucks with capacity ranging from 1,000 to 3,000 gallons. Presently no records of the scavenger waste quantities re- ceived are maintained at the landfill site. A daily count of vehicles and gallonage has been recommended in this report. 3.14 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENnaN Ind MURRELL, P.C. I H2M CORP. In 1978, a scavenger waste study was conducted over a two week period at the Southold landfill site. The gallonage of scavenger waste discharged on any particular day during the study period is depicted in Figure 3-5 and Table 3-3. 3.4.1 Future Scavenger Waste Quantities It can be expected that the increase in the volume of scavenger waste will follow the same general pattern as the growth of population for the area. At present, the only com- munity sewered is Greenport (Incorporated and a small portion of the unincorporated) with an estimated 1979 service popula- tion of 4,075. A wastewater facility plan is currently under- way for the Town of Southold. This plan is expected to recom- mend the expansion of the existing sewered area to include an additional 1,000 persons, which is only 6 percent of the total unsewered pOPulation of Southold. Therefore, this change will have a minor effect on the total scavenger waste volume received at the landfill. The Town of Southold has applied to the NYSDEC for a SPPES permit to continue the present means of scavenger waste dieposal until a more environmentally acceptable method can be developed in accordance with a compliance schedule keyed to the 201 program. Until then, the scavenger waste from the unsewered areas of Southold will continue to be disposed of at the landfill. Alternate means of disposal for the scavenger waste is not expected to be implemented until 1983. Inclusion of the details of the alternate means of disposal is beyond the scope of this report. Projected scavenger waste quantities that might be ex- pected at the Southold site are as follows: 1980 - 1,230,000 gal- Ions; 1981 - 1,260,000 gallons; and 1982 - I, 290,000 gallons. 3.15 ------------------- w .....

I H2M CORP. 4.0 EXISTING SITE ANALYSIS 4.1 Introduction This section provides a site analysis of the Southold exist- ing solid waste disposal facility. The scope of this section was determined after conversations with the NYSDEC officials re- garding the applicability of the Part 360 gUidelines to an exist- ing solid waste landfill. 4.2 Location As mentioned previously, the Southold landfill site is located north Qf North Road between Cox and Depot Lanes. The facility is situated in a rural, agricultural-industrial zoned area, approximately 2.5 miles east of Mattituck, one mile north of Cutchogue aqd 8 miles west of the Inc. Village of Greenport. 4.3 Transportation Systems The major access road leading to the landfill is North Road (County Road RQute 27), which is rated' as a four lane divided highway. North Road runs in the east-west direction from one end of the towqship to the other. All refuse collection vehicles use the North aoad since the entrance to the landfill is situated on North Road. The Southo1d facility does not require a rail transporta- tion system and is not serviced with a spur from the Long Island Railroad. Operational airports in the vicinity of the landfill in- clude Mattituck Airbase (3.0 miles southwest) and Suffolk County 4.1 I I I I I I I I I I I I I I I I I I I HOLZMACHER. McLIlNDO'" and MURRELL, P.C. I H2M CORP. Airport at Westhampton (17 miles southwest). The locations of these airports are not considered factors in the landfill opera- tions. 4.4 To~ography and Subsurface Conditions Southold Township is located on the north-east protrusion of Suffolk: County known as the "North Fork". This region of Long ISland is an e~tension of the Harbor Hill moraine (along north shore) which was produced during the advance of the last period of continental glaciation in this area of the north-east. The Southold solid waste disposal facility is situated on an outwash plain, south of the Harbor Hill moraine. The topograhpic fea- tures of the site area are described as that of rolling moraines and level to gently sloping outwash plains. From the surface down to a depth of more than 100 feet, the principal soils en- countered are classified as well graded sand and gravelly sand. The landfill site is underlain by a minimum of 60 feet of sand and gravel with local discontinuous zones of silt and clay. Figure 4-l displays a fence diagram representing the local geo- logy, three dimensionally. 4.5 Cli!Jlate 4.5.1 Temperature and Humidit~ The Town of Southold lies within the northern temperate belt and has a climate that is the result of both continental and maritime influences. The air masses and weather systems affecting the township have their origin principally over the North American Continent, but are in turn moderate and affected by the adjacent waters of Long Island Sound and the Atlantic Ocean. 4.2 I .

The mean annual temperature in Southold is about 510F. (lloC.), a few degrees higher than the mean annual temperature for New York State. This is due to the tempering influence of the bordering Atlantic Ocean and the Long Island Sound. The minimum average monthly temperatures occur in February with a range of about 280F. to 320F. (_20C. to OOC.). The maximum average monthly temperatures occur in July with a range from about 690F. to 750F. (200C. to 240C.). Average tem- peratures decrease as one travels eastward and, in general, temperatures found on the south shore are lower than those of the north shore at similar longitudes. High humidity is also a characteristic of Southold climate strongly influenced by the low altitude of the land mass and its proximity to large water bodies. 4.5.2 Precipitation The mean annual precipitation for Southold Township ranges from about 41 to 50 inches (104.1 to 127.0 em) per year and varies considerably throughout the Town*. An average annual pre- cipitation of 42 inches is equal to 730 million gallons per square mile per year (one inch of water per square mile is equivalent to 17.4 million gallons). Table 4-1 shows the monthly and annual inches of precipitation for ten stations within the Town and for *Crandell, H.C., Geology and Groundwater Resources of the Town of Southold, S.C., N.Y., USGS Water Supply Paper 1619-GG, 1963. 4.4 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP. three nearby stations for the years 1958 and 1959. The precipi- tation regime in Southold Township is characterized by increased precipitation in the months of March, August, November and Decem- ber, with a brief dry spell occurring in the summer. Table 4-2 lists the precipitation in inches taken at the Greenport power- house from 1964 to 1976. 4.6 Site Description The existing landfill site is located on a 41 acre tract of land north of North Road. The Town first initiated landfill operation at the existing site in 1954. Prior to this time, the residents utilized this as a dump site without supervision since 1940. Access to the site is through the main gate off North Road. The designated dump areas for self-haulers, private collections and scavenger waste vehicles are serviced by well maintained hardpacked dirt right-of-ways that emanate from the main access road reaching into the facility. Numerous hardpacked dirt right- of-ways are observed in the central interi~r of the facility. The natural environment surrounding the Southold landfill is typical of the type common throughout the entire length of Long Island's North Fork. Vegetation is predominantly oak-pine forest intermixed with northern hardwoods common to the Island's north shore. Pitch pine (Pinus ri~ida), white oak (Quercus alba), black oak (Quercus velutina) and red and sugar maples (AceI' rubrum and A. saccharum) are the specific dominants. Common herbaceous species include goldenrods (Solidago spp.) and numerous tall and short grass 4.6 I HOLZMACHER. McLENDON and Ij'IURRELL, P.C. I H2M CORP.

The composition of fauna on-site is the same as that found in landfills allover Long Island. Gulls, crows, starlings, field mice, rats and other small to medium sized mammals are abundant. Outlying areas provide habitat for higher vertebrates such as raccons (Procyon lotor), opposums (Didelphis marsupials) and raptorial bird species. The invertebrate community on the land- fill consists of mostly insects, specifically flies (Order Diptera) and a wide arraY of soil arthropods and microorganisms associated with organic matter decomposition. Adherence to NYSDEC Part 360 regulations for solid waste management prevents any of these species from becoming a nuisance or public health threat. Peripheral fencing at the Southold landfill consists of a 5 foot chain link fence. This fence circumscribes the entire landfill except for the two acres of buffer at the entrance to the site. Numerous groundwater aquifer formations at varying depths underlie the landfill site. The shallowest of these, the glacial aquifer, is cOmPosed of mostly stratified sand and gravel de- posita and is the only domestic water source for the area. From available water table contour maps and soil borings completed at three on-site locations, the groundwater levels at the land- fill reportedly varied from 3 to 5 feet above mean sea level. Surface water at the landfill is non-existent. 4.8 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLINDON and MURRELL, P.C. I H2M CORP. The location of the Southold landfill facility does not fall within the delineated flood boundaries determined by USGS. These boundaries have been plotted and are shown on Figure 4-2. The maximum flood boundaries represent the 100 year flood zones. Sandy soil characteristics and sound management practices preclude any problems with drainage at the landfill site. Final cover material on completed sections is graded to prevent pond- ing and erosion, and to reduce water infiltration into the solid waste cells to a minimum. Site utilities consist of an electric service line and a telephone line located in a booth in the central section of the landfill. Potable water and sanitary facilities are located in the maintenance building. Due to the remote, rural location of the landfill facility, noise geperated by excavation and landfill operations do not have a significant impact on the surrounding environment. All landfill equipment are fitted with ade~uate noise attenuation fea tures. 4.7 Groundwater Depths and Flows In 1974 HM&M under contract to the County of Suffolk, con- ducted a subsurface investigation for the Southold landfill site. Three core borings were taken at locations depicted in the site plan. The records of these borings are included in Appendix B of this report. The groundwater depths for the three locations are as follows: 4.9 I , I I I I I I I I I I I I I I I I I I FIGURE N2 4-2 LON G I S L A 11 JJ SOUND ". '. " .,...... < '. . < .

Village of Green- port, and a USGS report on the Hydrogeology of Suffolk County, Long Island, New York, by Jensen & Soren (1974), the altitude of the water table on the Upper Glacial aquifer is positioned approximately 5 feet above sea level. The landfill is positioned near the center of the groundwater mound. Below this aquifer is the Magothy aquifer, the upper surface of which varies from 100 to 150 feet below sea level.. Separating the Magothy from the underlying Lloyd aquifer is a semi-permeable layer of Raritan clay which somewhat inhibits the vertical flow of water from the Magothy to the Lloyd aquifer. The Magothy and Lloyd aquifers are not usable for potable purposes. A general geological cross-section of the Southold peninsula is shown on Figure 4-3. Accretion, the portion of precipitation which is not lost to evapotranspiration or direct runoff will flow in a vertical direction until it reaches the zone of saturation or water table. Upon reaching the water table the water will flow in a somewhat horizontal fashion in the direction of decreasing hydraulic gradient. The direction of flow is perpendicular to the groundwater contours. Groundwater flow of the Upper Glacial aquifer, in the area of the landfill site, is apparently in a northwesterly direction perpendicular to the 5 foot water table contour. 4.11 I I I I I I I I I I I I I I I I I I I FIGURE N2,4-3 Raf.

I H2M CORP. This flow continues in this direction until it reaches the Sound. Direction of this flow can be influenced by local well withdrawals. Water in the Upper Glacial aquifer flows at an approximate rate of 0.5 feet/day. Due to hydraulic differences, horizontal flow in the underlying aquifers is somewhat slower, with flow rates of approximately 0.2 feet/day in the Magothy and 0.1 foot/day in the Lloyd aquifer. If leachate plumes are generated by the landfill they will usually flow in the same direction as the water in the upper por- tion of the water table. 4.8 Adjacent Ground and Surface Water Quality 4.8.1 Groundwater Groundwater is the predominant source of drinking water supply in Suffolk County. USEPA requirements for the quality of drinking water are listed in Table 4-3. Alongside these standards, the New York State (NYS) and 1962 U.S. Public Health Service (USPHS) standards are listed. Prior to promulgation of the USEPA and NYS standards, the USPHS standards were the guide- lines followed by most water suppliers. Compliance dates, fre- quency of sampling and required analysis are shown in Table 4-4. The absence of water quality monitoring wells at the Southold landfill site preclude any detailed analysis of groundwater quality and specific flow patterns at this time. Groundwater and surface water data derived from the 201 Study (HM&M), and Long Island Water Resources Bulletin (LIWR-8) is, however, available for the nearby wells and surface waters.

The two closest water bodies lie approximately 2.2 miles to the south and southeast of the land- fill site. No chemical analysis is available for the pond to the south of the site. However, a chemical analysis for the southeast pond, also known as Wolf Pit Pond, was performed in 1974 with the following results: Parameter Wolf Pit Pond (Mattituck) Sample Results (mg/l)* 0.4 11.0 8.0 Nitrates (-N) Chlorides Hardness *Holzmacher, et al., 1974 "Water Quality Study in the Town of Southold".

I H2M CORP. 4.9 Leachate Generation and Movement 4.9.1 General When water from precipitation, surface runoff, or groundwater comes in contact with solid waste material in a landfill, a highly mineralized liquid is produced termed "leachate". Leachate has been defined as "a liquid, high in biological and chemical oxygen demand and chemicals (particularly iron, chloride and sodium), and hardness". As long as any moisture is present in a landfill, leachate will be produced. Fortunately, the landfill itself has the ability to absorb much of the leachate that is produced in the site. In a typical landfill site, approximately 75 percent of the refuse by weight consists of dry materials such as paper, rubber, glass, etc., that supplies little or no moisture to the site and in some cases, such as paper wastes, has the ability to absorb moisture in a landfill. The leachate will remain confined to the landfill site until the refuse reaches a point of saturation known as the "field capacity". The field capacity of a landfill is defined as "the liquid that can be retained by the fill against the action of gravity. The field capacity is rapidly obtained in humid areas of the country, but may not ever be reached in arid areas of the country. With the normal moisture content of refuse being 20 percent by weight, on Long Island for every foot of re- fuse, 6 inches of water entering the refuse would be required to produce leachate. After the field capacity is reached, any moisture entering the landfill site will displace an equal amount of leachate. The quantity of the leachate produced will be dependent on factors such as climate, topography, vegetation cover at the landfill, the type of material deposited in the landfill, and 4.21 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENOON and MURREll. P.C. I H2M CORP. the degree of compaction of the material deposited. The quality of the leachate produced will be affected by the composi tion and amount of refuse, its sorting, the amount of water in contact with the refuse, the temperature of the air and the interior. Leachate is produced when water comes in contact with re- fuse. This water is made available in several ways: 1. Direct precipitation and infiltration into the landfill. 2. Runoff from precipitation flowing down-slope, across the surface of landfill and percolating into the refuse. 3. Directly from the water table where refuse may be deposited. (Not the case at Southold). 4. Moisture contained in certain types of refuse (fruits and vegetables may contain up to 80% water by weight). In warm, humid climates leachate production is usually high because of the increased chemical and biological activity due to the high annual temperature, and the abundance of mois- ture. In cooler climates the production of leachate may be reduced near the working surface of the site, but because of the exothermic nature of the chemical and biological activity in the site, tempeatures at depth in a landfill may exceed 80oF. all year-round. Landfill sites in arid and semi-arid climates produce little if any leachate at all. The precipi- tation that is not lost to evaporation is usually rapidly ab- sorbed in the dry sections of the landfill site. The topography of the area around the landfill is also an influential factor in the amount of leachate a landfill can 4.22 I I I I I I I -1-.--- I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. potentially produce. Landfill sites located on flat areas or areas with gentle slopes are less likely to produce leachate than sites located in gullies, valleys or on hill slopes. The reason for this is that there is less likely to be runoff enter- ing a landfill site on a relatively flat area than in a valley or man-made depression. Steep slopes along valley walls, and excavation encourage runoff, and the flow is often directed into a landfill rather than away from it. Man-made and natural depressions also are often closer to the groundwater table than hill tops or flat plains. Proper site engineering can usually correct problems associated with topography. By definition, the working surface of a sanitary landfill should be covered daily by a thin layer of soil. The thickness of this cover ideally should be based on the thickness of refuse deposited that day. Ratios of 1:4 and 1:8, depth of cover to depth of refuse, are mentioned as being suitable for a daily refuse cover formula. The cover material should minimize the amount of moieture entering the landfill; be able to attenuate a portion of the leachate produced in overlying refuse cells; and reduce odor, entry by pests, the blowing of paper; and pro- vide a more eethetic appearance to the site. To reduce infil- tration of moisture, the solid cover should characteristically have low permeability and be resistant to shrinkage or cracking in dry weather. If the recommended ratios of cover to refuse are not acceptable for reasons of economics or availability of cover material, the USEPA recommends at least 6 inches of soil cover daily, one foot of cover for cells left unattended between 4.23 I I I I I I I I I I I I I I I I I I I HOLZMACHER. McLENDON and MURRELL. P.C. I H2M CORP. one week to one year, and a minimum of two feet of cover for completed working areas of a landfill. Field observations of the landfill sites in Suffolk County have shown that the land- fill operators deposit anywhere from no daily cover to a maximum cover of 8 inches per day. The average depth of daily cover at landfill sites in the County, including Southold, is between 4 and 6 inches. Vegetative cover on and around the site can have substan- tial influence on the amount of water that will eventually infiltrate into the refuse in a landfill site. Trees and low dense vegetation around a landfill site will reduce runoff by disrupting surface sheet flow and by keeping soil pores open. The same vegetation will also affect the annual evapotranspira- tion rate, which may in turn affect the groundwater table. Vegetation with high transpiration rates should be planted on the landfill cover in areas where work has been completed, and in areas surrounding the landfill site as a means of coping with excess runoff and high water table. The larger the landfill, the greater the potential volume of leachate produced. The amount of leachate produced is direct- ly dependent on the amount of refuse available in a landfill. However, the amount of leachate that will ultimately pass from a landfill is generally controlled more by landfill design than landfill size. Classification of refuse can be made on the basis of its potential to produce leachate. General industrial wastes, con- sisting of liquid and soluble industrial wastes and toxic 4.24 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. industrial ash have the greatest potential to produce leachate. Household and commercial refuse and rubbish, which includes empty tin cans, metals, paper and paper products, cloth and clothing, lawn clippings, sod, shrubs, dead animals and ashes, have a moderate potential to produce leachate. Solid inert wastes are least likely to produce leachate. This last group consists of earth, rock, concrete, asphalt, glass, plaster, manufactured rubber products, and clay and clay products. Slow refuse decomposition and leachate production are especially common in fills that are placed below groundwater level. (This is not the case in Southold where the landfill is above the groundwater table.) The slow stabilization is thought to be caused by anaerobic conditions that develop in such landfills. Conversely, aerobic conditions with an adequ- ate supply of moisture will cause rapid refuse decomposition and leachate production. Leachate production is also affected by the degree of com- paction of the refuse. Highly compacted refuse is less perme- able and porous than uncompacted refuse. In highly compacted fill there is less surface area exposed to chemical and bio- logical decay process. Compacted refuse also acts as an inhibitor to the downward percolation of fresh water and leachate. Fungaroli* examined the production of leachate in a land- fill site and in a laboratory model. From his investigation he was able to deduce certain facts regarding the quality of *Fungaroli, A.A., 1971 Pollution of Subsurface Water by Sanitary Landfills, USEPA. 4.25 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. leachate produced. Fungaroli found the chemical quality of the leachate varied with the rate of leachate production. The following are characteristics of increased leachate production: 1. Drop in the value of pH. 2. Increase of iron concentration. 3. Increase in sulfate concentration. 4. Increase in the concentration of suspended solids. Landfills where refuse is buried beneath the surface of the groundwater table will typically undergo anaerobic decay. The products of anaerobic decomposition of solid wastes include: methane, CO2, high levels of nitrate, BOD and COD, and very often putrid odor due to the saturated landfills and the anaerobic de- compos%tion products created. Aerobic decay produces end products such as S04' H20 and inert residue since chemical and biological activity are a function of temperature, BOD and COD values usu- ally are directly proportional to changes in landfill temperature. 4.9.2 Leachate Control at Southold Landfill Existence of large amounts of soil underneath the Southold landfill provides an adequate buffer zone between the refuse fill and the groundwater, which presumably minimizes leachate collection or treatment system at present. Proper daily opera- tion of the sanitary landfill controls leachate pollution. Surface water is kept from entering the landfill site which reduces the rate of leachate production and the time it takes for the landfill to reach field capacity. Runoff and surface water flow are controlled by terracing and grading. Operating methods for leachate control include proper spreading and compaction of refuse to a layer not exceeding two 4.26 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP. feet in depth, application of adequate daily, intermediate and final cover, and seeding the completed area with transpiration type of vegetation. Good mixing, spreading and compaction of solid waste allows for improved leachate absorption in the land- fill and prevents excessive differential settlement as refuse decomposes. As pointed out in the previous section, the chemical analy- sis of the groundwater samples about a mile south of the landfill does not indicate contamination of groundwater. Since no data are available for the groundwater conditions in the immediate vicinity of the site it is difficult to predict the level of contaminant addition by the landfill to the groundwater. In accordance with the NYSDEC requirements, a leachate monitoring program for the Southold landfill is recommended. Details of this program are discussed in a separate section of this report. Due to the proxi- mity of the landfill to the center of the groundwater mound, this program should be given the highest priority. 4.10 Methane Gas Generation and Control 4.10.1 General The conversion of organic wastes to methane with the sub- sequent use of the methane for useful energy purposes has been common-place in sewage treatment plants for more than half a century. The bacterial-chemical processes used in the sewage sludge digester are the same as those that occur in a landfill. A significant difference exists between the two systems, how- ever, in that, in the sludge digester, it is possible to care- fully control the environmental factors and the nutrient feed 4.27 I I I I I I I I I I I I I I I I I I I HOLZMACHER. McLENOON and MURRELL. P.C. I H2M CORP. rates in a way that optimiz.es the bacterial activity, while the landfill is a very haphazard biochemical processing facility. In fact, when one considers the narrow range of environmental factors and nutrient levels in which the bacteria thrive, it is amazing that gas production in a sanitary landfill takes place at all. The less-than-optimum conditions that exist in a typi- cal sanitary landfill may very well result in a total gas gener- ation potential equal to but less than a few percent of the theoretical maximum. A number of investigators have over the past 15 years or so attempted from both theoretical and experi- mental approaches to determine the ultimate gas production that could result from the decomposition of solid waste. The three chief constituents of solid waste are carbon (C), oxygen (0) and hydrogen (H); some nitrogen (N) and a little sulphur (8) are also present. Through microbiological fermenta- tion, these five constituents in different combination likely produce four gases: chiefly carbon dioxide (C02) and methane (CH4), and with minimal production of ammonia (NH3) and hydro- gen sulfide (H2S). Aerobic action is produced by microbes that live on the free oxygen derived from air; anaerobic action, by microbes that live in conditions of oxygen deprivation. Since CO2 results from the former and CH4 from the latter, the produc- tion of CO2 is highest in the first months of a landfill's existence. As CO2 production declines, CH4 production rises; then both level off to about equal levels (45 to 50 percent) after about 2 to 3 years. Gases are generated for long periods 4.28 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. of time, in some cases up to 50 years, until all biodegradable material has been exhausted. Methane, a major constituent of "landfill gas", is lighter than air, and therefore, tends to rise and escape from the land- fill. However, the density and depth of earth cover over the sanitary landfill tend to prevent the methane gas from escaping upward. The entrapped gases will, therefore, develop a positive pressure sufficient to develop equilibrium between the rate of generation and the rate of escape. This pressure exerts itself in all directions within the confinements of the sanitary land- fill and not only will the gas migrate upward, but also downward and laterally. 4.10.2 Methane Gas Control In spite of the uncertainty with regard to the quantita- tive production of methane gas in sanitary landfills, it is certain that enough gas will be produced in even the least active site to require the designer to consider the potential migration of gas beyond the boundaries of the landfill property. The cause for concern lies in the fact that methane is a com- bustible, and in certain mixtures with air, (5 to 15 percent by volume) an explosive fuel. If it were to migrate to adjoin- ing property and be accumulated in a confined space where it might be ignited, the potential for explosion does exist and there are indeed a number of reported instances where this has happened. Fortunately, the technology of gas migration prevention systems is sufficiently developed that the designer can provide 4.29 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. a system that will provide adequate protection to adjoining pro- perty. In many instances such as in the case of the Southold landfill, depending on soil type and the extent of the peri- pheral undisturbed soil buffer area, it will not be necessary to construct any gas evacuation system. Where it is necessary, however, to locate sanitary landfills in close proximity to other developments, such systems may be required, and monitor- ing systems will be absolutely mandatory. Monitoring will re- present a continual on-going expense, for the extent of gas migration at a given site can vary from time to time depending on such factors as rainfall, gas generation rate, and applica- tion of irrigation water. 4.10.3 Methane Migration at Southold Landfill To date no complaints from the surrounding landowners have been registered with the Town of Southold concerning lateral methane gas migration or vegetation kills on the adjacent un- developed areas. Although methane migration poses no significant problems at the present time, as a precautionary measure this report recom- mends routine methane monitoring at the landfill site and sur- rounding structures. 4.30 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP. 5.0 EXISTING LANDFILL OPERATIONS I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 5.0 EXISTING LANDFILL OPERATIONS 5.1 Introduction This section evaluates the existing operations at the Sout- hold sanitary landfill. A brief discussion relating to landfill operations was provided in Section 1.0 - EXISTING CONDITIONS. A detailed operating plan is presented herein which illustrates fulfillment of the regulatory requirements applicable to the Sout- hold landfill. 5.2 Receipt of Solid Waste The landfill accepts residential, commercial, institutional and some agricultural waste generated from within the confines of the Town of Southold. The commercial and agricultural waste that are permitted include waste cardboard, packaging materials, scrap materials, plastics and waste vegetation. At this writing, the Town is installing a spotting booth at the entrance of the land- fill area where all incoming vehicles will be identified and directed to their designated disposal areas. Improvements and relocation of access roads within the site is also being consider- ed to achieve more efficient landfill operations. Ordinary refuse, both residential and commercial arriving in private collection vehicles, is directly dispatched to its desig- nated ultimate disposal area. Private cars and small pickups carrying refuse are diverted to an area where they discharge into an earth carved storage pit. Once filled a pay10ader scoops up the refuse from the pit and transports it to the designated land- fill area. Bulky materials (demolition debris, tree stumps, wood 5.1 I I I I I I I I I I I I I I I I I I I HOLZMACHER. McLENDON and MURRELL, P.C. / H2M CORP. and brush) are disposed of in the northern section of the land- fill where they are leveled to the surrounding elevation. Scaven- ger waste vehicles are directed to two separate, uncovered, un- lined, 100 x 75 foot lagoons located in the north-west section of the landfill site. Here the waste is dumped and allowed to leach into the soil. Approximately 25 feet separates the bottom of the scavenger waste lagoons from the groundwater table in this area. Bundled newspapers are separately collected in a 25 cubic yard container. Residents are required to bundle the newspapers themselves. The collected newspapers are periodically hauled away by a private contractor for recycling purposes. Approxi- mately 200 tons of newspaper'is received at the landfill site annually. Similarly, the Town maintains a separate facility for container storage of bulky metal items such as refrigerators, stoves, washing machines, etc., which are also removed from the site periodically by a private contractor. The Town reportedly does not receive any revenues for the recyclable materials collected at the landfill. It is recommended in this report that the Town have firm contracts for the collec- tion of such materials including certain schedule of revenues pay- able to the Town. The revenue schedule should be prepared on the basis of prevailing values of the recyclable materials. The Southold solid waste facility is not equipped to handle and does not accept any form of hazardous wastes. These hazardous wastes include any radioactive materials, toxic chemicals (i.e. spent industrial acids, pharmaceuticals, irritants, corrosives, industrial by-products), biological wastes, flammable and/or 5.2 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. explosive materials. In the event of an unauthorized disposal, the landfill foreman is directed to notify the Suffolk County Department of Health Services and the Regional Office of the New York State Department of Environmental Conservation. The land- fill also does not accept any derelict vehicles or grossly over- sized scrap. 5.3 Method of Disposal The Southold landfill utilizes the "trench fill" method for its solid waste disposal. This technique involves placing refuse in an excavated portion of the site, spreading and compacting it to smallest possible volume, and then covering it with the ex- cavated soil. The site preparation procedure currently being implemented at the landfill consists of excavation of soil to a point where the vertical separation between the flat bottom of the excavated trench and the existing groundwater table is a minimum of 5 feet. Refuse is then spread and compacted in2 foot layers and covered daily with 4 to 6-inches of excavated soil. Lift heights are limited to between 4 and 6 feet including an approximate 12-inch layer of intermediate cover. Present fill sequence at the Southold facility is accomplish- ed by the placement of solid waste into cells along an approximate 300 foot horizontal (east-west) face in the designated disposal area. The brush and demolition wastes are deposited immediately east of this area, progressively in a north-south direction. Additional rows of solid waste cells are compacted against this face in a southerly direction until a completed lift covers the 5.3 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. disposal area. The operation is then repeated beginning at the north end of the disposal area with the construction of a new cell face on top of the existing lift layer. As the various northern sections of the landfill reach their final lift heights, the disposal operations will gradually shift to the newly excav- ated southern and eastern ends of the site. The elevation control of solid waste lifts is accomplished by the personal jUdgment of the experienced equipment operators. Compaction of solid waste in the landfill is attained by multiple passes of the landfill equipment consisting of a rubber tired wheel loader over the refuse along the sloped working face. A compaction density of the in-place refuse is estimated at 600 lbs./cu.yd. 5.4 Cover Material Management Cover material quantities at the landfill can be considered virtually unlimited given the available on-site excavation. Ap- proximately 80 cubic yards of cover material (sand, gravel, mixed with some clay) is mined each day for uses within the landfill. In addition, on an average 35 cubic yards of material per day is used by the highway department, and 40 cubic yards of sand is sold to private contractors. Calculations, which follow, of available cover material indicate that if current practices are maintained that sufficient on-site cover material will be available until the landfill reaches full capacity. Total volume of cover material available at the landfill site has been computed as 490,000 cubic yards. The land volume available 5.4 I I I I I I I I I I I I I I I I I I I HOLZMACHER. McLENDON and MURRELL. P.C. / H2M CORP. for refuse placement is calculated to be approximately 903,000 cubic yards. Thus, cover material required for landfill opera- tions over the life of the landfill, assuming a 4:1 ratio by volume of solid waste to cover material, is approximately 181,000 cubic yards. This leaves about 309,000 cubic yards of sand for utilization by the highway department and for sale to private contractors. At the existing rate of 75 cubic yards per day or 27,000 cubic yards per year, it can be safely assumed that con- tinuation of present cover material management practices will pro- vide adequate supply of cover material for the remaining life of the landfill site. Any surplus material can be sold to generate additional renvenues. 5.5 Personnel Requirements and Responsibilities As previously discussed (Section 3.0) the work force at the landfill site consists of four full-time employees with rotating schedules such that at least two persons are at the landfill at all times. Overall control of the facility is the responsibility of the Superintendent of Public Works. Maintenance and adminis- tration are under his authority. However, the landfill foreman is responsible for site operations and any immediate problems that may arise at the site. Spreading, compacting and covering of solid waste in an environmentally safe manner are the prime responsibil- ities of all personnel. Their duties also include the excavation and transport of cover material from the mine site as well as general clean up. 5.5 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 5.6 Convenience/Transfer Stations The Town of Southold does not maintain any convenience cen- ters or transfer stations for private vehicles. From its source of origin, all solid waste is directly brought to the existing Southold sanitary landfill facility in private cars, small pick- ups or collection vehicles for final disposal. 5.7 Landfill Records Due to the absence of a weighing scale, accurate records of solid waste received at the Southold landfill are difficult to maintain. Only large size collection vehicles which carry a specific volume of solid waste can provide a fairly accurate count of waste quantities. Amounts arriving in private cars and small pickups can only be estimated. As a part of our recommenda- tion, a sample monthly landfill record sheet has been developed and included in Appendix C of this report. Scavenger waste trucks entering the landfill site must fill out a record sheet indicating basic information required by the Suffolk County Department of Health Services. The driver of each scavenger truck is required to record the date, company and location of pump out on sign-in sheets located at the personnel shelter. No records of the quantity of scavenger waste are main- tained. 5.8 Winter and Inclement Weather Operation No major problems concerning winter and inclement weather operations have been reported in conversations with the Superin- tendent of Public Works. Good drainage at the site together with 5.6 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON end MURRELL, P.C. I H2M CORP. well maintained roadways keep the facility operable during incle- ment weather. 5.9 Facility Control Signs: Adequate signs are posted in full view at the entrance of the landfill giving all pertinent information as to the days and hours of operation, restrictions and regulations. Installa- tion of additional signs is presently being considered by the Town as a step toward improvement of traffic flow within the site. Regulations: The Southold facility has few regulations that pertain to the disposal of wastes at the landfill. Signs indicate that the facilities are for use of residents of Southold only. However, there is no enforcement of the residency restriction. The employees only enforce that refuse be disposed of in its designated area and that no hazardous wastes are disposed of at the landfill. The Town presently does not have a solid waste disposal ordinance. 5.10 Traffic Flow Control The small scale of this rural operation combined with the low volume of on-site vehicles at any given time, precludes any major problems with traffic flow. The traffic is adequately handled by the existing on-site primary right-of-ways with re- quired width and shoulders to accomodate most two-way traffic. During peak flows of the summer months, an employee occasionally is needed to direct the incoming vehicles. The peak disposal time is during the weekends of the summer months when the population increases by 50 percent. Despite this, no unusual vehicle traffic problems occur. 5.7 I I I I I I I I I I I I I I I I I I I HOLZMACHER. McLENDON and MURRELL. P.C.! H2M CORP. 5.11 Contingency Plans for Control of Undesirable Conditions Reportedly to date, there have been no prolonged work stop- pages at the Southold landfill site due to uncontrollable circum- stances. Undesirable conditions include fires, dust, litter, water contamination, odor, noise, vectors, unusual traffic con- ditions and equipment breakdowns. An on-site well provides supply of potable water and water for fire fighting purposes to extinguish any small refuse fires. In the event of large fire emergencies, additional aid can be sum- moned from the Cutchogue Volunteer Fire Department located approxi- mately 1.5 miles southeast of the landfill. Dust at the facility is. kept at a minimum due in part to well maintained dirt roadways. Water spraying techniques are employed if dust becomes a nuisance. The most frequent undesirable condition that must be dealt with at the Southold Landfill, is that of high velocity winds which in turn cause litter problems. The combination of being surrounded by flat plains and being situated near the shore causes the area to receive a predominantly westerly wind. This, therefore, creates a problem of litter being blown about the landfill site and surrounding properties. The landfill utilizes highway snow fencing in strategic locations opposing the prevailing winds, to control the litter nuisance. This method of control has, thus far proved inefficient, collecting only a fraction of blowing litter. To overcome the problem of the blowing litter, in addi- tion to the existing snow fencing, this report recommends confining the landfill operations to a more manageable area, covering 5.8 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C.! H2M CORP. the refuse immediately following placement and compaction in the landfill and creating some type of permanent buffer zone against the wind direction. The Southold facility presently employs a laborer under the Federal CETA program to aid in litter control and general landfill clean-up. Periodically, landfill employees police the areas outside the site to collect blown litter. Care is taken at the landfill to inhibit the amount of water infiltration into the solid waste cells. The procedure is accom- plished by grading the cover matter in such a way as to prevent ponding and erosion. The uppermost 4 to 6 inches of cover mate- rial placed on completed cells is also of a composition suitable for plant growth. Promoting vegetative growth on solid waste cells is an important method of removing infiltrated water by means of evapotranspiration. Odors emanating from the landfill do not have an impact on the surrounding environment due to its remote location. Prompt compaction and covering of the refuse during the entire working day eliminates many of the odor problems commonly associated with landfill operations. A problem does exist, however, at the site of the uncovered scavenger waste pits. The noxious odor of con- centrated raw waste is quite distinct in the northwest section of the site, especially following disposal by a scavenger waste vehicle. No odor complaints from the adjacent residents have been registered. The isolated location of the landfill precludes any noise problems to surrounding areas caused by landfill operations. All landfill equipment, however, are fitted with suitable noise .suppression devices. 5.9 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. The vector problems at the landfill are kept to a minimum by the application of good landfilling techniques. The daily cover placed over the refuse has been found to be effective in denying food sources and harborage to common landfill vector such as rats, mice and insects. The seagull population that frequent the site is substantial but is not considered a seri- ous nuisance or health hazard. 5.12 Equipment Needs As previously discussed, the existing equipment at the Sout- hold landfill, without the assistance of highway equipment, is inadequate until the Town acquires new equipment to replace the existing front-end loader. The equipment needs at the site can be fully met by a new payloader in combination with an open body dump truck. During the hours when the solid waste arriving at the site is at a minimum, the payloader could perform the daily duties of excavating cover material and top loading the dump truck for hauling and stock- piling at the designated areas. For the rest of the day, the payloader could be utilized for refuse handling duties. This ar- rangement could result in improved landfill operations, increased equipment life and lower equipment operating and maintenance costs. The existing front-end loader can either be repaired and kept on- site as a back-up equipment or be traded in to offset the cost of purchase of new equipment. In the latter option, the Town will have to rely upon highway department equipment during downtime of the regulation landfill equipment. 5.10 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 5.13 Illustration of Fulfillment of Regulatory Requirements In accordance with the NYSDEC Part 360 Regulations, the Town of Southold is required to illustrate its compliance with the 360 Regulations inasmuch as they apply to an existing solid waste disposal facility. Following is an itemized delineation of the Sta te regulations as they are out lined in Sec tion 360.8 of "Pro- posed New Rules and Regulations - Solid Waste Management Facilities 6 NYCRR Part 360". Under each item is presented the fulfillment of the requirement by the Town 's existing landfill. 5.13.1 Section 360.8 Facilities Requirements A. General Requirements for all Solid Waste Management Facilities - 1. Solid waste shall not be deposited in and shall be pre- vented from entering surface waters or groundwaters. At the Southold landfill site, the solid wastes are deposited a minimum of 5 feet above existing groundwater levels. 2. Solid waste management facilities shall not be placed on agricultural land designated Class I and/or Class II land, if such land is being actively used as cropland within an agricultural district formed pursuant to the Agriculture & Markets Law. The land now being used for the Southold solid waste facility is zoned for industrial use. The landfill location has been used continuously since 1954. 5.11 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL. P.C. I H2M CORP. 3. Leachate shall not be allowed to drain or discharge into surface water (except pursuant to a SPDES permit issued pursuant to ECL Art. 17 Title 8 Parts 750-757) and shall not contravene groundwater quality standards established by the De- partment pursuant to ECL Sec. 17-0301. The Southold solid waste disposal facility is not provided with a conventional leachate collection or treatment system such as an impermeable liner. Additional groundwater monitoring is recommended to evaluate the potential for groundwater contamina- tion, in this sensitive area. 4. Salvaging, if permitted, shall be controlled by the facility operator within a designated salvage area and shall not interfere with operations, create hazards or nuisances. Only authorized salvaging of scrap metal and newspapers by private contractors is permitted at the site. Two roll-off con- tainers are kept on-site and designated as storage for metals and newspapers. 5. Access to facility shall be permitted only when an attendent is on-duty. This provisions shall not apply to facil- ities such as transfer stations without operating mechanical equipmen t. The landfill is bordered by a 5 foot chain link fence, cir- cumscribing the entire site. Authorized access to the site is only permitted between 7:30 A.M. and 5:00 P.M., 7 days a week. The Town does not operate an off-site transfer station. 6. Access to and use of the facility shall be controlled by fencing, gates, signs or other suitable means. 5.12 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. Access to the landfill facility is controlled by a main gate off North Road. Adequate signs are posted detailing the hours and restrictions of operation. However, it is recommended that additional signs be posted within the site to help locate the de- signated disposal areas. 7. Blowing papers and litter shall be confined to refuse holding and operating areas by fencing and other suitable means. The landfill employs highway snow fencing in designated dis- posal areas. These current practices are inadequate and it is recommended that additional controls be provided to confine blow- ing litter. 8. Vectors, dust and odors shall be controlled by effec- tive means so that they shall not constitute nuisances or hazards to health, safety or property. Adequate supplies of on-site cover material and good land- filling techniques minimize vector and odor problems. This is accomplished by 4 to 6 inches of daily cover applied to the dis- posal area in use. Dust problems are controlled by hardpacking of road surfaces and with the utilization of water spraying tech- niques. 9. On-si te roads used to transport solid wastes shall be maintained passable and safe at all times. All roads within the site are well maintained, hardpacked, dirt surfaces. These roads have adequate drainage and remain passable at all times. 10. Safety hazards to all persons on the facility shall be minimized. 5.13 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. Traffic and disposal within the site is strictly controlled by landfill personnel to minimize safety hazards. All landfill equipment is regularly maintained and provided with safety fea- tures (i.e. back-up warning horn, roll cages). Personal safety equipment (i.e. hard hats, gloves) are also provided. 11. Noise levels at solid waste management facility shall be controlled. No monitoring of the noise levels at the landfill has been performed to date. However, due to the remote location of the site, the noise intensities are barely detectable beyond its property boundaries. Several site visits by the Engineers also substantiate this statement. 12. Adequately heated and lighted shelters for operating personnel shall be provided for at the facility. A safe drink- ing water supply, sanitary toilet facilities and telephone or radio communication shall also be provided. A heated and lighted shelter with a telephone is provided on- site for operating personnel. Water supply and sanitary facilities are located in the maintenance building. 13. Adequate numbers, types and sizes of properly maintained equipment shall be available to the facility during all hours of operations. Available equipment on-site is properly maintained at all times. However, requisition of additional heavy equipment is necessary. The Town has initiated the process of acquiring State funds for purchasing new landfill equipment. 5.14 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 14. Shelter for mobile equipment shall be provided for routine maintenance and repair. A maintenance garage is located in the southwest corner of the landfill site for storage and light maintenance of landfill equipment. Extensive repair work is performed in the Department of Highways garage. 15. Open burning shall be prohibited except pursuant to permit issued by the Department under Part 2B of the Title Mea- sures shall be taken immediately to extinguish any non-permitted open burning. Open burning of solid waste material is prohibited at the Southold landfill. However, brush material has occasionally been disposed of through controlled burning. This practice has been discontinued since notification from NYSDEC. 16. Solid wastes shall be confined to an area which can be effectively maintained, operated and controlled. Final deposition of solid waste at the landfill site is spread, compacted and covered in a prescribed, environmentally safe manner. Procedures used to transfer the refuse to the final disposal area are ineffective. Recommendation to improve opera- tions and control of the landfill is provided in Section 9.0 of this report. 17. Hazardous wastes shall be accepted only at facilities which have been specifically approved by the Department for the processing Or disposal of the specific waste. The Southold landfill facility is not equipped to handle hazardous wastes. However, in a recent incidence some 55 gallon 5.15 .'Ii...... " /1.'-'\' I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON end MURRELL, P.C. I H2M CORP. drums of waste oil from Mattituck Airbase unnoticeably were dis- posed of at the landfill site. Personnel are now instructed not to allow any of these wastes. 18. Records shall be maintained at every facility receiving hazardous wastes detailing the physical and chemical nature, ori- gin, quantity, disposal location within the facility disposal methods for said wastes, and such other information as the Depart- ment requires upon closing of the facility the said records shall be filed with the Department. This regulation does not apply to the Southold facility. 19. Reports on forms acceptable to or provided by the De- partment shall be submitted at a frequency specified in the opera- t ion permit. The Town of Southold stands ready to provide any information or reports requested by the Department. 20. Facilities shall be maintained and operated to func- tion in accordance with the permit issued pursuant to this part and the design and the intended use of the facility equipment in use at each facility shall be maintained to operate effectively contingency plans approved by the Department for emergency situa- tion shall be implemented in accordance with the plans terms. The landfill is maintained and operated SO as to function in an environmentally acceptable manner. The equipment at the site is maintained to operate effectively. Contingency plans for emer- gency situations are in effect. 21. Solid waste management facilities shall not be operated or constructed on flood plains unless provisions have been made to prevent encroachment of flood waters upon said facility. " 5.16 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. The Southold landfill is not situated on a designated floodplain. B. Requirements for Specific Solid Waste Management Facil- ities Sanitary Landfill - 1. A vertical separation of at least 5 feet shall be maintained between solid waste and the groundwater table or bedrock. The Southold landfill does maintain a minimum of 5 feet vertical separation between the deposited solid waste and groundwater table. 2. The required horizontal separation between deposited solid waste and any surface waters shall be determined for each sanitary landfill by reference to soil attenuation characteris- tics, drainage and natural or man-made barriers. There are no substantial surface water formations in close proximity to the landfill site. 3. A minimum of three groundwater monitoring wells, or more as determined by the Department, shall be provided at a new or modified facility and at least two wells shall be located downgradient from the solid waste fill area. Appropriately loca- ted, constructed and monitored wells off-site may be used to satisfy this requirement. Where determined by the Department, monitoring wells may be required at facilities in existence on the effective date of this part. As of now, the Southold facility does not have the required three groundwater monitoring wells. however, monitoring wells are recommended in this report. 5.17 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 4. Water monitoring programs shall be undertaken where required by the Department to meet testing and frequency sche- dules established in the Operation Permit. The landfill presently does not have any water monitoring programs. The Suffolk County Department of Health Services main- tains records on groundwater quality by regularly analyzing water samples taken from wells in the vicinity of the landfill. 5. Baseline water quality conditions (reflecting annual seasonal data) of both groundwater and surface waters shall be established prior to depositing solid waste at a new site. This provision is for a new landfill and does not apply to the existing facilityat Southold. 6. Decomposition of gases generated within the sanitary landfill shall be controlled so as not to create hazards to health, safety or property. To date, there have been no problems with health, safety or complaints associated with decomposition gases generated within the landfill. The porous nature of the sandy soil allows the gases to vent vertically throughout the landfill and there is no present evidence of widespread horizontal gas migration. This report recommends that the Town periodically monitor the peri- phery of the landfill for methane migration. 7. Specific cover and compaction requirements: (a) Solid wastes shall be spread in 2 .foot layers or less and compacted upon decomposition at the working face. The working face shall be restricted to the smallest area practic- able. 5.18 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. The Southold landfill conforms to the regulation by compact- ing the refuse in 2 foot layers and adding cover upon compaction. The working face is kept to an area of manageable proportion. (b) Lift height shall not exceed 10 feet. Lift heights at the landfill are limited to between 6 and 8 feet. (c) Daily cover shall be placed upon all exposed solid waste prior to the end of each working day. A daily cover of 4 to 6 inches of soil is applied prior to the end of every working day at the landfill. (d) Intermediate cover shall be applied whenever an additional lift of refuse is not applied within 30 days. An intermediate layer of 12 inches of cover material is applied at the landfill in an additional lift of refuse is not to be applied within 30 days. (e) Final cover shall be applied: (1) Whenever an additional lift of refuse is not to be applied within one year. The Southold landfill deposits a 24 inch soil cover to any area not to be used for additional re- fuse disposition within one year. (2) To any area of a landfill attaining final elevation within 90 days after such elevation is at- tained. A 24 inch final cover is applied to all areas that have attained final elevation. 5.19 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. (3) To an entire landfill which is the subject of an application that is denied or a permit that ter- minates for any reason within 90 days of such denial or termination. Does not apply to the Southold facility. 8. Cover material and drainage control structures shall be designed, graded and maintained. to prevent ponding and ero- sion and to reduce to a minimum infiltration of water into the solid waste cells, consistent with the operation permit and with this part. Cover material at the landfill is graded and maintained to prevent ponding and erosion and to reduce to a minimum infiltra- tion of water into the solid waste cells. 9. A grass or ground cover crop shall be established and maintained on all exposed final cover material within four months after placement. Upon completion of the landfill and placement of final cover, standard operating procedure at the landfill is to have the top 6 inches of cover material composed of loamy soil on which to establish a grass cover to reduce infiltration and blowing sand. A final site utilization plan dictating specific requirements is discussed elsewhere in this report. 10. Soil cover integrity, slopes, cover vegetation, drain- age structures, groundwater monitoring facilities and gas venting structures established pursuant to a permit shall be maintained for a period of 5 years after the completion of the landfill and placement of final cover material. 5.20 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL. P,C. / H2M CORP. Soil cover integrity, slopes and cover vegetation are ex- pected to be maintained for a minimum of 5 years after the comple- tion of the landfill and placement of final cover material. 11. No hazardous or industrial wastes materials, which when combined together will produce hazardous wastes, shall be dis- posed of in a sanitary landfill except pursuant to specific opera- tion permit authorization. The Southold landfill does not accept hazardous wastes of any kind. 12. All fill areas or excavations at a sanitary landfill shall terminate no closer than 50 feet from the boundary lines of the property on which the sanitary landfill is operated. At the present time, no fill areas or excavations are opera- ted within 50 feet of the property boundary lines. 13. A survey bench mark shall be established and maintained on the site. A survey bench mark is established and maintained on the Southold landfill site. 14. Upon transfer of ownership of a sanitary landfill site, a provision shall be included in the property deed indicating the period of time during which the property has been used as a land- fill, a description of the wastes contained within and the fact that the records for the facility have been filed with the Depart- ment. Said deed shall also reference a map which shall be filed with the County Clerk, showing the limits of the landfill areas within the property. Does not apply to the Southold facility to date. 5.21 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 6.0 ALTERNATIVE COURSES OF ACTION I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C, I H2M CORP, ALTERNATIVE COURSES OF ACTION Introduction Given present quantities and methods of solid waste disposal, the life of Southold's existing sanitary landfill facility, as estimated in earlier sections, is six years. Accordingly,the Town must begin to find alternatives for disposal of its solid waste between now and 1985. Various alternatives that are avail- able to Southold are presented in this Section. Detailed evalua- tion of these alternatives as to their technical, environmental and economical feasibility are beyond the scope of this report. The Federal Resource Recovery Act of 1976, which is now be- ing implemented, is likely to require the closing of all Long Island landfills. This is primarily due to the designation of Long Island of having a soie source of potable water. Present draft regulations may require such closings by July 1984. Pre- liminary State guidance may require double lining of new or un- used landfills together with leachate collection and treatment systems. As these requirements are developed and enforced, the Town will be required to conform accordingly. 6.0 6.1 6.2 Alternative Solid Waste Management Systems Any alternative course of action must, of course, be consider- ed in its proper time phase. We have divided the solid waste man- agement plan for the Town of Southold into three distinct time periods: 1. 2. 3. Immediate future (present to one year). Intermediate future (one to six years). Long range future (six to 20 years). 6.1 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. A discussion of alternatives and proposed courses of action for the Town are presented in the following subsections. 6.2.1 Immediate Future Pending the approval by NYSDEC of the application for permit to operate a solid waste management facility, we anticipate that the Town will be able to continue its present method of solid waste disposal (i.e. sanitary landfill). The contents of this report will fulfill the present Part 360 requirements after the installation of groundwater monitoring wells. We have recommend- ed initiation of a groundwater monitoring program by constructing three monitoring wells at specified locations at the landfill site. Methane venting systems are not deemed necessary at this time, and therefore, are not included in the recommendations. Methane monitoring, however, is recommended. There are a few other minor recommendations which should be implemented in order to improve the operating conditions at the site. For the purpose of the development of solid waste disposal alternatives, we are assuming that the Town will be permitted to use its present land- fill until its available capacity is exhausted. It is recommended that the Town closely examine various long range alternatives outlined herein regarding their costs, bene- fits and associated environmental constraints. The examination of long range alternatives could be performed in cooperation with other Eastern Long Island towns individually, jointly or by Southold on its own. 6.2 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 6.2.2 Intermediate Future During this time frame, the Town must begin to plan for long range solid waste management alternatives to assure their avail- ability for implementation well in advance of complete utilization of the existing site. Contingent upon the results of an in-depth evaluation of the long range alternatives, the Town may opt to: 1. Consider acquisition of additional landfill space within the Town, preferably near the existing landfill site. Located adjacent to the northeast corner of the site, are approximately 10 acres of privately owned land. This land is presently being utilized as a sand pit mining operation. Further evaluation of this site will be discussed later within this report. This alter- native would enable the collection system to remain unchanged, providing that environmental factors will permit this. If the waste generation were to escalate as projected, approximately 1,500 acre-feet of land volume is estimated to be required for straight landfilling during the period 1985-2000. The new site will have to be designed to meet the stringent and exacting stan- dards of the NYSDEC outlined in Part 360 as it pertains to opera- tions and leachate/gas monitoring and control and pending Federal regulations. State and Federal funding for a new sanitary landfill is not available for engineering and site preparation. State funding (25%) is available for site buildings, equipment, etc. Straight sanitary landfilling is not viewed as a resource recovery method of solid waste disposal. Whatever the case may be, if landfilling is selected as the most feasible alternative (provided this is a permitted option) 6.3 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. the Town should commence planning for land acquisition and prepara- tion in order for the new site to be available to receive solid waste by the beginning of the year 1985. 2. Initiate planning for a solid waste resource recovery program. The resource recovery option may be divided into two major categories: low technology option and high technology op- tion. Low technology options include source separation and recovery of items such as newspapers, tin cans and glass. The cans are separated by a magnet, and the bundled newspapers re- moved by hand. As pointed out previously, the Town already has a small scale voluntary newspaper separation program at the land- fill. This program can be scaled-up, or perhaps made mandatory, for additional recovery of newspapers. It is estimated that approximately 20 percent of newsprint in the waste stream can be recovered by source separation. Recovery of about 50 percent of aluminum and tin cans can be achieved using a magnet. The re- maining solid waste will require landfilling. The cost of re- covery materials under low technology option will have to be weighted against the revenues obtainable from the prevailing markets. The high technology options consider recovery of energy and secondary materials. These include incineration with heat re- covery, shredded refuse as RDF (refuse derived fuel), hydrosposal (Black Clawson system being used at Town of Hempstead), and pyro- lysis. Other alternatives include shredding with ferrous and/or non-ferrous metal recovery, shredding and high compaction baling, with metal recovery and composting. The amount of residue requiring 6.4 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. ultimate land disposal for the high technology alternatives varies, as do the capital and operating costs, and revenues from the re- covered resources. The small quantities of solid waste generated within the Town of Southold (113 tpd in 1985 and 165 tpd in 2000) would rule out as economically prohibitive the construction and operation of the Town's own high technology resource recovery facility. The cost of initiation, construction operation and maintenance of such a facility, coupled with the small return on recycled materials would make it economically non-competitive with other methods of dis- posal. However, larger regional resource recovery alternatives may well be economically feasible, attributable mainly, to the economy of scale. Several regional resource recovery options are available for the Town of Southold and discussed in the subsequent long range future alternative courses of action (see Section 6.2.3). As stated previously, the Town must further explore these options in the immediate future time frame for their availability as a means of solid waste disposal in 1985. 6.2.3 Long Range Future The solution to Southold's future solid waste disposal problems may ultimately be in a regional, or bi-town resource recovery pro- gram. The increased volume of solid waste from a number of sur- rounding towns combined with better recovery technology and more markets for recovered materials may make resource recovery econom- ically feasible. Only extensive cost evaluation will determine the most feasible, long range alternative for Southold. A Town-owned high technology resource recovery program may prove expensive and 6.5 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP. may not provide economics of scale. On the other hand, a two town or regional approach may introduce political, economic and implementational problems, particularly in terms of solid waste collection and site selection process. Considering the present solid waste disposal situation that exists with the neighboring Towns, we have briefly examined the following alternatives. 1. Continued land disposal: As pointed out in the inter- mediate future plan, sanitary landfill may prove to be the most economical alternative despite its increased capital costs due to regional environmental considerations and lack of aid. How- ever, the Town should consider regional resource recovery options in terms of overall benefits derived from such planning and pend- ing Federal requirements. 2. Solid waste composting: Composting of refuse is defined as "the aerobic, thermophilic degradation of putrescible refuse by micro-organisms." Using large volumes of oxygen, bacteria and other micro-organisms to stabilize putrescibles and kill pathogens, producing a uniform, relatively dry, humus like material. Current American composting is limited to a few non-subsidized commercial plants, pilot research facilities and small municipal operations using windrow composting. The prospects for successful composting in the United States have been hampered primarily by two factors: (1) Composting at best represents only a partial solu- tion to the disposal problem. (2) The economic viability of the process is determined by the sale price of the end product (fertilizer). 6.6 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. Although composting is one of the oldest solid waste manage- ment practices, its full use has yet to be realized. The almost uniform record of failure of commercial composting plants in the United States, coupled with the lessening percentage of food waste in refuse, indicates little promise for this system as the sole method of municipal refuse disposal. 3. Five Town Resource Recovery Program: A regional resource recovery facility comprising the five eastern towns of Suffolk County, namely Southold, Southampton, Riverhead, East Hampton and Shelter Island could be constructed at a centrally located site. This facility would be served by direct haul in collection vehicles from the communities located within economical haul distances. Re- motely located communities would transfer haul in large tranfer trailers from one or more transfer stations. An optimum transpor- tation network could be developed to divide the direct haul and transfer haul communities. Table 6-1 shows projected population and solid waste quanti- ties for the five towns through 1995. The combined waste genera- tion on a 7 day week basis is estimated at 389 tpd in 1980, 466 tpd in 1985, 555 tpd in 1990 and 661 tpd in 1995. If a regional resource recovery facility were to be built for the design year of 2000, it would probably be sized for 1,000 tons per day includ- ing an additional 25 percent to account for peak periods. While initially, the solid waste quantities may not be adequate to main- tain the cost of operation at an acceptable level, the increased future quantities certainly seem to be in the capacity range of a number of resource recovery facilities in planning or operation 6.7 ------------------- TABLE 6-1 PROJECTED POPULATION AND SOLID WASTE QUANTITIES FOR FIVE EASTERN TOWNS THROUGH 1995 POPULATION (1) SOLID WASTE QUANTITIES (2), t~y 1980 1985 1990 1995 1980 1985 1990 19 5 Southo1d 21,016 23,814 26,716 29,972 36,000 41,400 46,700 53,300 Southampton 47,200 54,837 64,352 75,518 56,600 68,400 83,500 101,500 Riverhead 23,412 26,529 30,363 34,572 28,100 33,100 39,400 46,700 East Hampton 15,549 18,992 22,066 25,637 18,700 23,700 28,600 34,500 Ol Shelter Island 2,228 2.790 3,324 3,960 2,700 3,500 4,300 5,300 . 00 TOTAL FIVE TOWNS 109,405 126,962 146,821 169,839 142,100 170,100 202,500 241,300 (389 tpd) (466 tpd) (555 tpd) (661 tpd) , NOTES: (1) (2) 1978 Population Survey - LILCO The solid waste quantity projections for the three Towns are based on both estimated regional per capita generation rates and per capita generation rates for the Towns of Riverhead and Southo1d. tpy indicates "tons per year" tpd indicates "tons per day" (7 days/week) :I: o r- N ;: )> o :I: m :0 ;: n r- m Z C o z ..

An extensive marketing analysis would have to be performed to determine potential revenues from the recovered energy and/or secondary materials. 4. Disposal at the Town of Brookhaven's Proposed Resource Recovery F~cility: Preliminary planning is underway for construc- tion of a solid waste resource recovery facility in the Town of Brookhaven. The design capacity of the proposed facility is un- known at this time. This facility is scheduled to be operational in 1985 and can be considered a viable future alternative for Southold. A transfer station facility can be located at Southold's existing landfill site. This would compact the solid waste into large transfer trailers for transportation to the Brookhaven fac- ility. expected to be situated in the proximity of the Brookhaven National Laboratory. The haul distance of approximately 30 miles would justify the construction of the transfer station. Arrange- ments could be worked out as to the extent of Southold's involve- ment in the on-going resource recovery planning. Mutual benefits could be realized by both towns. They include: (a) Brookhaven facility will tentatively become opera- tional at approximately the same time the present Southold landfill reaches capacity. (b) Because of a projected significant growth in Brook- haven from 1985 to 2000 and beyond. the facility will pre- sumably be designed with considerable excess capacity. This could be available to Southold and/or other eastern towns for a period of years until Southold and/or the eas- tern towns could justify their own facility. 6.9 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 5. Extending alternative 4 above, a regional transfer sta- tion facility linking Southold with Riverhead and/or all four towns with Brookhaven facility may also present a feasible alter- native. 6. Regional sanitary landfilling: If the resource recovery options are found uneconomical, consideration could be given to a regional sanitary landfill combining one or more towns with Sout- hold. This may prove to be the most attractive alternate. The sanitary landfill, if at all permitted by the NYSDEC, would be designed to comply with the prevailing regulations. Specifically, Towns of Southold and Shelter Island could join to form a regional landfill since the Town of Shelter Island is in need for a long- term method of its solid waste disposal due to the Town's non- compliance with Part 360 regulations. 7. Baling system: For the past several years, Southold Town officials have been considering installation of a high den- sity solid waste baling facility. There are several baling fac- ilities in operation throughout the United States, the closest being in the Town of Smithtown. High pressure compaction is a volume reduction process where the air filled spaces (voids) are removed from the solid waste. The formation of solid blocks of refuse will decrease the volume required for disposal resulting in an extension of site life of a landfill. Studies have shown that average volume reduction ratios can range from 5:1 to 10:1 (loose refuse to baled refuse) depending on the effectiveness of the compaction process. Baling of solid waste results in improved refuse management practices. The bales can be easily deposited one on the top of 6.10 I I I I I I I I I I I I I I I I I I I HOLZMACHER. McLENDON and MURRELL, P.C. / H2M CORP. the other, similar to building blocks, and heavy duty landfill equipment requirements are also reduced since no further compac- tion of in-place bales is required. The problem of blowing litter due to disposal of loose waste, particularly at the Southold land- fill, can be alleviated by baling. Environmental impact of bale disposal at sanitary landfill is similar to that of common loose refuse disposal at landfills. The solid waste bales do resist water percolation to a certain extent which in turn impedes leachate production in a landfill. However, the bale fills still require expensive leachate collec- tion and treatment systems. There may be some reduction in cover material requirements particularly in daily and intermediate cover. Major drawbacks of a baling system include high capital and operating expenses, landfill preparation requirements and its inability to offer resource recovery which is so highly empha- sized in these days. Costs associated to a baling facility and bale fill shall be compared with the cost of straight landfilling. For the Town of Southold, due to availability of adequate inexpensive land for waste disposal purposes, the baling option does not appear to be economically justifiable. 8. Regional Co-disposal Facility: Co-disposal is defined "as a method in which solid waste is disposed of with sludge from sewage treatment plants utilizing a process such as incineration with or without heat recovery." A regional facility could be established combining one or more towns with Southold. Sewage 6.11 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. sludge from throughout the area could be disposed of at the fac- ility. The attractiveness of this alternative will depend heavily on the quantities of sludge generation from within the service area. Federal funding is available for sludge handling which can be utilized to partially offset the disposal costs. Here again, economics of co-disposal for the Town of Southold alone does not seem favorable. 6.3 Alternative Courses of Action for Scavenger Waste Disposal As discussed before, the Towns of Southold and Shelter Is- land are presently undertaking a scavenger waste study (septic and cesspool waste management) as a part of the 201 facilities planning for their respective areas. Upon completion of a scaven- ger waste disposal system, all scavenger waste now received at the Southold landfill will presumably be diverted and processed at the proposed facility. Therefore, for this report, development of alternative courses of action for scavenger waste disposal is eliminated from consideration. Treatment of scavenger wastes is mandated under a SPDES permit issued to Southold. 6.4 Cost Comparison of Long Range Alternatives In this section we have presented a preliminary comparison of long range solid waste management alternatives applicable to small communities such as the Town of Southold. It should be emphasized that the costs developed herein (Table 6-2) are to be used for com- parison purposes only and that selection of any of these alternatives requires detailed technological and economical evaluation. 6.12 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENOON and MURRELL, P.C.

Straight sanitary landfilling: This alternative calls for acquiring additional land beyond the lifetime of the existing landfill, preparation of the site to ensure proper environmental protection and operating the site in conformance with the State regulations. This option is of course predicated on the fact that Southold will be allowed land disposal. 2. Baling with sanitary landfill: The only significant difference between this alternative and straight landfill is the high compaction of solid waste achieved during baling process thereby reducing ultimate land volume requirements. Since baling does not offer recovery of resources, no potential revenues are available to reduce the operating expenses. Environmental con- straints of straight sanitary landfill are equally applicable to the baling alternative. 3. Modular incineration with heat recovery: Although com- paratively higher than the two previously mentioned alternatives, modular incineration offers Southold a resource recovery potential. In recent years, small incinerators equipped for energy recovery have proven beneficial to small communities. Several companies manufacture small incinerators that can recover energy and meet air pOllution standards. A regional facility, perhaps with the Towns of Ri verhead and/or Shelter Island, and increased energy re- venues may well bring the net cost of disposal within the accept- able range of straight land disposal. State and Federal funding are also available for such type of energy recovery systems. The Town is strongly recommended to further explore this alternative. 6.14 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 4. Transfer Station at Existing Site and Haul to Brookhaven's Proposed Resource Recovery Facility: The overall cost of this alter- native greatly depends on the tipping fee Southold would be required to pay at the Brookhaven facility. A transfer station facility with stationary compactor would be constructed at the existing landfill site and all of Southold s solid waste would be compacted in large transfer trailer vehicles for haul to the proposed resource re- covery facility approximately 30 miles away. The existing personnel would be utilized to operate the transfer station. With the assump- tion of $15. tipping charges, this alternative presently does not appear to be economically attractive. 5. Composting: Cost-effectiveness of solid waste composting for Southold lies in the sustained market availability of compost products. Composting in the United States has been unsuccessfully tried in many places using different concepts. Reliable costs for composting are not readily available. The most recent composting cost of :j)26.70 was reported in March 1979 issue of "Waste Age". If this cost were to apply to Southold, composting indicates little promise as the sole method of municipal refuse disposal. 6.15 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C.

I H2M CORP. 7.0 LEACHATE MONITORING PROGRAM The Southold landfill site does not presently have a leachate monitoring well system. As part of requirements to comply with 360 regulations, we are recommending the immediate installation of such a system inasmuch as it applies to an existing site in a sensitive area. A detailed description of the program, based on the criteria outlined in the NYSDEC Content Guidelines for Plans and Specifications for Solid Waste Management Facility, follows. 7.1 Purpose Leachate monitoring well system has a two-fold purpose. First, the wells are utilized as piezometers to observe and measure fluc- tuations of water table; and second, to collect samples of ground- water for periodic analysis and monitoring. 7.2 Procedure The spacing and number of wells depends on the direction of groundwater flow which, in case of the Southold landfill, is north- easterly. A minimum of three monitoring wells should be installed at locations shown in Figure 7-1. Two of the wells should be in- stalled downstream of the landfill in order to intercept ground- water flow from the site. The third well should be located in the landfill site. Based on the depth of the water table, as shown in the 1974 core borings, or obtained from the new soil borings during construction of the monitoring well system, placement of screens should be determined. The top and bottom of the screen should be below the lowest seasonal groundwater level. 7.1 I I I I I I I I I I I I I I I I I I I FIGURE N2 7-1 / /' / / / / / I I , \ \ \ DIRECTION OF \ REGIONAL GROUNDWATER FLOW --- o '" '" "- "- \ \ \ \ \ o \ \ I I I I / / / / / \ \ \ CD \ CD LEGEND LANDFILL SITE BOUNDARIES LEACHATE MONITORING WELL LOCATION ~FERRED BOUNDARY OF LEACHATE SCALE' 1"~400' LECHATE MONITORING SYSTEM WELL LOCATIONS TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT PLAN AND REPORT JUNE 1979 HOLZMACHER, McLENDON & MURRELL, P.C.I H2M CORP.

J. 7.2 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP. 7.3 Well Construction The proposed wells will be a minimum of 4 inches in diameter (i.d.) and will be constructed of plastic pipe or galvanized steel depending on well location. Similarly, the screen will be plastic or galvanized steel. Each well will be constructed with an impermeable seal of either bentonite or cement grout in the annular space between the bore hole and the well casing preventing infiltration of surface water into the well. Initially, one small capacity well pump and associated pip- ing will be furnished and used to obtain water samples from all wells. After all construction is completed and a follow on moni- toring program is implemented, it will probably be cost-effective to purchase additional pumping units for permanent installation. A portable generator set will be used to supply power to the well pumps. 7.4 Baseline and Routine Water Sampling Analysis Initially, two samples from each sampling point will be taken approximately two weeks apart. The sampling parameters will be determined as required and approved by the NYSDEC. The routine sampling will be performed quarterly and as additionally required by the NYSDEC. 7.5 Cost A breakdown of the preliminary cost of the recommended leach- ate monitoring well system is presented in Table 7-1. The total cost of proposed construction, engineering, initial laboratory analy- sis, final evaluation report and contingencies is estimated at $75,000. in 1979 dollars. 7.3 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C.

I H2M CORP. 8.0 FUTURE SITE UTILIZATION PLAN I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP. FUTURE SITE UTILIZATION PLAN General Any proposal for future use of a sanitary landfill site must be made with full recognition of the characteristics of the de- posited material. Decomposition of solid waste material in a landfill may take up to 20 years depending on the climatic condi- tions. With decomposition of the contained refuse, settlement of the landfill must take place. Generally, the settlement is about 20 percent of the initial lift heights. Construction of a struc- ture on such sites must be carefully planned not only to overcome the landfill bearing capacity problems but also the detrimental effects of both leachate and methane gas generated beneath the structure. The future site utilization plan must be compatible with the surroundings, zoning and esthetics of the area. Potential land uses must be consistent with the Southold future solid waste man- agement plans. 8.0 8.1 8.2 Southold Site Utilization Plan Holzmacher, McLendon & Murrell, P.C. contracted with Land De- sign Associates (LOA), Landscape Architect-Land Planners, to pre- pare a land development program for the Southold landfill. The LOA report and plan has been incorporated in the appendix of this report. Potential uses of the site are: 1. Revegetation - nursery liner stock for municipal land- scaping material. 8.1 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 2. Wildlife refuge for both birds and small game. 3. Agricultural - lease for farm use only after possible effects from methane gas production proven harmless. Potential users of the site may include general public, schools and universities with earth science programs, bird watchers and naturalists. In addition to the above mentioned users, the site could also be utilized as a nine hole golf course, motorcycle course, athletic fields or cross-country running course. Because of the site's centralized and remote location, the existing landfill would be an ideal place for installation of a transfer station facility, should the Town elect to transport its solid waste long distance to a resource recovery facility such as Brookhaven or a regional facility with the five eastern towns. Multi-fold benefits could be derived from such planning: 1. No alterations in the existing collection practices would be required. 2. Availability of existing facilities such as maintenance building, roadways and fencing could result in substantial sav- ings in capital investments. 3. Obstacles generally associated with site selection for a new solid waste facility such as public resistances and inter- communi ty political jurisdictions could be minimized. 8.2 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 9.0 FINAL RECOMMENDATIONS I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. 9.0 FINAL RECOMMENDATIONS We recommend the following courses of action for the Town of Southold solid waste management. 9.1 Existing Sanitary Landfill Facility A. Acquire landfill equipment. (NOTE: the Town is present- ly in the process of acquiring the recommended landfill equipment). Replace the existing Allis-Chalmers payloader with a new payloader for excavation and refuse management duties. Additionally, ac- quire a new open body dump truck to assist the payloader in cover material hauling and stockpiling. Retain the existing pay loader as a backup machine or trade-in provided Highway Department equip- ment are available during downtime. B. Immediately implement a groundwater monitoring program. Install three monitoring wells at proposed location for baseline and routine water sample analyses. This is to meet minimum re- quirements for NYCRR Part 360. C. Periodically monitor methane gas migration. The fre- quency of such monitoring is suggested as quarterly. Methane migration tests should be conducted around the periphery of the existing and old landfills and the surrounding buildings. The Town could either purchase a portable methane gas detector and conduct the test or contract the testing services. D. Control blowing litter. Existing management practices induce the problems of blowing litter and debris, as well as ex- cessive equipment manuvering. As previously discussed under existing operating methods, private collection vehicles follow 9.1 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. I H2M CORP. the perimeter road to the north of the landfill to discharge directly into an open waste cell. Private cars and small pickups discharge into a storage pit located towards the south side of the site. The front end loader clears out the pit when full and unloads the refuse into the same open waste cell as the collection vehicles. The open transporting of refuse some 300 feet between the storage pit and waste cell causes wind blowing of refuse throughout the site. It is recommended that the collection vehicles continue to discharge at the designated waste cell. However, after the front end loader clears out the storage pit, it should discharge the refuse into a separate waste cell located in closer proximity to the storage pit (maximum 100 feet). This will reduce the manu- vering time of the front end loader between the storage pit and waste cell and also refuse exposure to the wind. Both waste cells should be maintained at a minimum operating size, to help lessen effects of the wind. These practices should continue for the subsequent operating areas of the landfill. This may require relocating the storage pit so it remains relatively close to the waste cells. In addition to confining the operating areas to a manageable size, all deposited solid waste shall be covered as soon as possible. Other recommendations to alleviate the blowing litter problem at Southold landfill have been delineated elsewhere in the report. E. Maintain daily records of all incoming solid waste and scavenger waste. A sample record sheet is included in this report. 9.2 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP. F. Continue landfill operation in an environmentally sound manner such as proper spreading, compaction and covering of solid waste material, maintenance of equipment and site facilities. G. Develop refuse disposal ordinance. The Town of Southold presently does not have an ordinance to control its refuse manage- ment. It is recommended that the Town initiate development of an ordinance, similar to neighboring towns such as Riverhead, out- lining terms and conditions for the waste haulers. The new or- dinance shall include, but not be limited to: 1. A dumping license fee schedule for various types of collection vehicles (such as household refuse, land clearing-demolition waste, etc.) 2. Residency requirements. 3. License fee for scavenger waste disposal. 4. Special permits for unusual municipal solid waste. 5. Prohibition for disposal of hazardous wastes. H. Separation of recyclable materials. Separation of re- cyclable materials such as newspapers, white goods (refrigerators and like), etc., not only reduces the volume of solid waste to be disposed of, but can also generate additional revenues. It is recommended that the Town further encourage separation of news- papers at the source as well as at the landfill site by locating the recyclable receiving containers in close proximity of the waste disposal areas convenient to the haulers. The Town should also bid annual contracts with the collectors of recyclable materials. 9.3 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENDON and MURRELL, P.C. / H2M CORP. 9.2 Immediate Future A. Initiate detailed evaluation of various long range alter- natives available to the Town as described in the report. B. Commence planning for final utilization of existing land- fill site. Explore various alternative uses best suited for the Town of Southold. C. Con tinue mon i tori ng of grolwdwa ter and methane gas migra- tion. A schedule for implemen ta t ion 0 f the a foremen tioned recommend- ations is presented in the Time Task Chart see Figure 9-1. 9.4 I I I I I I I I I I I I I I I I I I I HOLZMACHER, McLENOON and MURRELL, P.C.

APPENDIX E SOUTHOLD LANDFILL DEVELOPMENT PROGRAM "- SOUTHOLD LANDFILL ANALYSIS EXISTING SITE PROBLEMS 1. High exposure a. wi nd b. visual Result: extensive dust blowing, paper and debris blowing SITE SOLUTIONS 1. Reduce exposure a. Plant wind screen buffer around perimeter of site where fence is open. Result: will produce reduced wind impact; will produce visual barrier; and will prevent paper and debris from blowing off site POTENTIAL SITE USES 1. Revegetation a. perimeter wind screen buffer b. plant nursery liner stock which can mature and be used as material for municipal landscaping 2. Wildlife Refuge a. When the plant material and grasses grow for a few years, the revegetated areas will provide refuge for birds and small game. 3. Transfer Station a. When the Brookhaven Facility is under construction a transfer station can be incorporated on the front four acres. b. This facility is normally a two-story structure and can be buried in the hillside on the front four acres so that the building will not be obtrusive. '" page 2 LONG TERM SITE USES 1. Recreation a. Presently, the area has extensive recreational resosurces. Therefore, this site has no practical recreation potential within the next 10-15 years. b. In the far future, the site may offer the following poss ibfl iti es: 9-hole golf course motorcycle course athletic fields cross country running course 2. Agriculture a. Experimental plot can be planted to determine the potential for crop production and the possible effects of methane gas on various crops. b. If crop production proves feasible, the land could be leased for farm use. SITE ANALYSIS The landfill site lies north of Route 25 in a wide open field condition, with some stands of woodland on the northern extremities of the site. This wide open condition presents several problems. The landfill operation is extremely visible and unsitely. The wind exposure is severe and results in dust, trash and debris blowing over the surrounding area. The soil conditions are essentially an extremely sandy loam base friable soil that has high porosity. The deeper soils are essentially sand with spotty clay lenses. IMMEDIATE SITE SOLUTIONS The most immediate problem to be solved is the high visibility and the wind blowing problem. A wind screen and visual buffer should be planted at the perimeter boundaries of the property that do not contain any vegetation. As the landfill develops hedge rows should be planted intersecting the landfill too. In addition to the screen planting, grasses should be planted to prevent wind and water erosion of the soils. The enclosed specification suggests the types of grasses and procedures. " . page 3 POTENTIAL SITE USES Due to the extensive amount of open land in the area and the high quality of existing recreation lands around Southold this landfill site does not have great potential for the next 15 to 20 years. However, in the meantime, the site could serve other uses. Revegetation of the site with nursery liner stock could serve as a poten- tial source for landscape material for the town to use on municipal plant- ing projects in parks, roadways, etc. Another use could be to plant a few blocks of crops to see how they react to the landfill conditions. If the crops do well, the land has lease potential for agricultural uses. When the Brookhaven facility is ready the site is well situated to serve the North Fork as a transfer station site. This would require about 4 to 5 acres, leaving the balance of the site available for the other uses previously listed. Other potential use in the far future may be a golf course, motorcycle track, equestrian center, or let it remain a revegetated nature preserve. .. . ......
