Box 324 Wappingers Falls, New York 12590 Attention: Hon, Joseph Ruggiero, Supervisor Reference: Castlepoint Recreation Site Well Test Results Dear Supervisor Ruggiero & Board members: This office is in receipt of the second quarter water quality results from the Castlepoint Landfill as performed by Conrad Geoscience Corp. on June 16th, and July 19'h, 2004 (copy enclosed). The results for the supply well that serves the bathroom facilities indicates the following: PARAMETER RESULTS MCL • Iron 0.425 ppm 0.300 ppm • Lead 0.120 ppm NE • Zinc 0.305 ppm 5.0 ppm • Magnesium 35.5 ppm NE The iron level is in excess of the New York State Part 5 Drinking Water Code Maximum Contaminant Level (MCL). While there is no MCL specifically for lead (and depending on future lead levels detected) the results may be in excess of NYS Part 5 Drinking Water Code. The specific language regarding Lead Action Levels in said code is as follows: The lead action level is exceeded if the concentration of lead in more than 10 percent of one liter first draw tap water samples collected during any monitoring period and computed in accordance with subdivision (c) of this section exceeds 0.015 milligrams per liter. It should be noted that the samples were taken at the start of the season (i.e. after the wells had been shut down for winter). This long lapse in use could affect the water quality results, particularly if the water is not run for a substantial period prior to sampling. Joseph E. Paggl Jr., P.E. Ernst Martin, Jr., P.E„ L.S. Charles R. Del Bene, Jr., P.E. Hon. Joseph Ruggiero - 2 - September 10, 2004 RE: Castlepoint Recreation Site It is our opinion that the water system for the Castlepoint Recreation Bathroom facilities should be shut down until this situation can be rectified. This should include immediate additional testing, and ultimately, could require that some type of filtration measures be installed. By copy of this letter, we are notifying Mr. Peter Marlow of the Dutchess County Health Department, Mr. Michael Tremper of Camo Pollution Control, and Mr. Ralph Holt of the Town Recreation Department to obtain their input on the matter. Please feel free to contact this office if you have any questions regarding this matter. Very truly yours, Joseph E. Paggi, Jr., P. JEP/PJP.law Enclosure cc: Hon. Gloria Morse Town Board: File Hon.

FIELD ACTIVITIES RECEIVE_ On June 16 and July 19, 2004, Conrad Geoscience personnel visited the site SE 1 14 % quarterly groundwater sampling. Samples were to be analyzed for routine water quaTQWN CLEF)"' parameters as defined by 6 NYCRR Part 360-2.11(d)(6). Two on-site monitoring wells were sampled and analyzed: PMW-8R, PMW-9. The on-site supply well (SW -1) was tamed off for the winter months and was not sampled during this quarter. Monitoring Well PMW-8R is a 27' deep down -gradient monitoring well utilized to sample the unconsolidated sediment aquifer. PMW-9 is a 59.6' deep down gradient monitoring well utilized to sample the bedrock aquifer. SW -1 is an up -gradient well used to supply water to the on-site facilities. Prior to sampling, static water level elevations were measured in each of the stipulated monitoring wells (PMW-8R, PMW-9). Well volumes for each well were calculated. Groundwater from Monitoring Well PMW-8R and PMW-9 was purged until all physical water quality parameters had stabilized. Samples were collected from Monitoring Wells PMW-8R and PMW-9 using dedicated polyethylene bailers and shipped to York Analytical Laboratories for analysis of baseline parameters as defined by 6 NYCRR Part 360-2.11(4)(6). Samples were collected from the onsite supply well, SW -1, via the spigot inside the on-site supply shed. RESULTS Monitoring Well PMW-8.R The following metals exceeded NYSDEC standards in PMW-8R: Iron (5.95 ppm); magnesium (40.1 ppm); sodium (27.7 ppm) and manganese (1.94 ppm). Other inorganic parameters exceeding NYSDEC standards include color (10,000 pt/cl) and total organic carbon Castle Point Landfill Groundwater Monitoring File #CW000100 August 19, 2004 (9.6 ppm). All results are presented in the attached table (analytical report appended). No other inorganic parameters exceed NYSDEC standards. No VOCs were detected in PMW-8R Monitoring Well PMW-9 The following metals exceeded NYSDEC standards in PMW-9: Iron (12.8 ppm); manganese (0.359 ppm), and copper (0.34 ppm). Other inorganic parameters exceeding NYSDEC standards include color (250 pt/el). All results are presented in the attached table. No other inorganic parameters exceeded NYSDEC standards. No VOCs were detected in PMW-9 Supply Well The following metals exceed NYSDEC standards in the supply well; Iron (0.425 ppm); lead (0.120 ppm); zinc (0.305 ppm) and magnesium (35.5 ppm). No other inorganic parameters exceed the NYSDEC standard in the supply well. No VOCs were detected in the supply well. All results are presented in the attached tables. Analytical reports are appended In accordance with the State's July 21, 2004 approval letter, the frequency of groundwater monitoring will be reduced from quarterly to annually. Perimeter Monitoring Wells PMW-8R, PMW-9 and the on-site supply well will be sampled in the second quarter of 2005, and annually thereafter. If you have any questions, please do not hesitate to call.

On June 16, 2004, Conrad Geoscience personnel measured the percentage of methane (CH4), percentage of the lower explosive limit (LEL), and percentage of oxygen (02) from 12 gas vents around the perimeter of the landfill. Background LEL readings were 0.0%. Measurements were also collected in and around nearby structures. Sampling was conducted in accordance with the approved procedure for landfill gas monitoring. Measurements were taken within the vents, and above and beneath the opening of these vents if methane was detected inside. Of the 12 vent locations monitored, 3 locations (GV -7, GV -8 and GV -13) had detectable concentrations of methane within the gas vent. LEL readings in the on-site gazebo were 0.0%. LEL readings in the on-site maintenance building were 0.0%. Data from all gas monitoring points are presented in the attached table. Landfill gas monitoring for the third quarter of 2004 has been tentatively scheduled for September. If you have any questions or comments please do not hesitate to contact me.

FIELD ACTIVITIES On March 23, 2004, Conrad Geoscience personnel visited the site to conduct quarterly groundwater sampling. Samples were to be analyzed for routine water quality parameters as defined by 6 NYCRR Part 360-2.11(d)(6). Two on-site monitoring wells were sampled and analyzed: PMW-8R, PMW-9. The on-site supply well (SW -1) was turned off for the winter months and was not sampled during this quarter. Monitoring Well PMW-8R is a 27' deep down -gradient monitoring well utilized to sample the unconsolidated sediment aquifer. PMW-9 is a 59.6' deep down gradient monitoring well utilized to sample the bedrock aquifer. SW -1 is an up -gradient well used to supply water to the on-site facilities. Prior to sampling, static water level elevations were measured in each of the stipulated monitoring wells (PMW-81?, PMW-9). Well volumes for each well were calculated. Groundwater from Monitoring Well PMW-8R and PMW-9 were purged until all physical water quality parameters had stabilized. Samples were collected from Monitoring Wells PMW-8R and PMW-9 using dedicated polyethylene bailers and shipped to York Analytical Laboratories for analysis of routine parameters as defined by part 6 NYCRR Part 360-2.11(d)(6).

On October 30, 2003, Conrad Geoscience personnel measured the percentage of methane (CH4), percentage of the lower explosive limit (LEL), and percentage of oxygen(02)from 12 gas vents around the perimeter of the landfill. Measurements were also collected in and around nearby structures. Sampling was conducted in accordance with the approved procedure for landfill gas monitoring. Measurements were taken within the vents, and above and beneath the opening of these vents if methane was detected inside. • Of the 12 vent locations monitored, three locations (GV -1, GV -7, GV -8) had detectable concentrations of methane within the gas vent. + Only GV -7 had detectable concentrations above 100% of the LEL of methane inside the vent pipe. + LEL readings in the on-site gazebo were 0.0%. + ' The on-site maintenance building was closed for the winter. Data from all gas monitoring points are presented in the attached table. Landfill gas monitoring for the first quarter of 2004 has been tentatively scheduled for February.

Final "As- Built" Map, prepared by Paggi, Martin and Del Bene, Lip., dated last revised 10109100. This information is submitted in response to a previous correspondence from Mr. Lent, dated 3123101. In that correspondence, Mr. Lent informed the Town that the Certification Report for the Landfill was unacceptable, citing that "An unsigned Report was submitted which was also not certified by an individual licensed to practice engineering in the State of New York." Apparently, a signed and sealed copy was never subsequently transmitted to your department, and an approval letter never issued from your department. The Town of Wappinger is now seeking to close out the Project, and obtain a Release of Retainage on their Landfill Closure State Assistance Grant. The Release of Retainage will require a letter from your department indicating acceptance of the Landfill Closure Certification Report. Your assistance in this matter would be greatly appreciated. Please feel free to contact this office if you have any questions or comments regarding this matter. We would be glad to meet with you, or schedule an onsite inspection if you feel that would be beneficial. Thank you.

June 9, 1998 New York State Department of Environmental Conservation 21 South Putts Corners Road New Paltz, New York 12561 Attention: Frank Kelly Reference: Castlepoint Landfill Closure Dear Mr. Kelly: As you are aware, Hudson Canyon Construction, Inc, has been working on the above referenced project for the last month. In general, the work has progressed smoothly and site inspections by this office have proved to be favorable. As outline in our previous correspondence dated May l la`, 1998, this office has identified two areas at the site that contain waste material and that are located outside of the originally presumed landfill boundary. Because these areas are outside of the Contract boundaries, any remedial work in the area would constitute an addition to the Contract and would require a Change Order. The areas in questions are illustrated on the enclosed plan, and are more particularly described as follows: A. Area "A" is located at the northwesterly section of the landfill, along the westerly edge of the existing entry road. The additional waste in this area was encountered on May 5h, 1998 during construction operations to relocate the entry road as per the Contract Specifications. In order to remedy the situation, this office instructed the Contractor to excavate the additional ,waste, relocate it to the main landfill mass, cover the waster with clean fill, and compact the entire area. The excavation was then backfilled with 1'/z" crushed stone, covered with clean, compacted fill. The excavation measured 30 feet long by 24 feet wide by 6 feet deep, B. Area "B" is located at the northerly section of the landfill along the entry road up to the existing ballfidd fence. This area exhibited leachate bubbling up to the surface during a routine N.Y.S.D.E.C. inspection. Further exploration work conducted on May 8a', 1998 revealed that additional waste materials were present in the area indicated on the enclosed plan. This office has studied two methods of dealing with this extra waste: • The first method would be to excavate the additional waste, relocate it to the main landfill mass, cover it and compact it, The remaining excavation would then be backfilled with clean compacted fill. Any leachate encountered wouid have to be pumped out and hauled to an approved disposai location. • The second method would be to leave the additional waste in place, cap it with 18" of clay, 24" of existing, onsite clean material, and topsoil, seed and mulch the entire area. Joseph E. Paggi, Jr., P.E. Ernst Martin, Jr„ P.E., L.S. prrnred on recycled paper Mr. Frank Kelly - 2 - June 9, 1998 RE: Castlepoint Landfill Because of the risks inherent to the first method (i,e.: Do not know the vertical extents of the waste, do not know the magnitude of the leachate) and due to the fact that it would involve substantial amounts of direct content with waste materials, it is the opinion of this office that the second method (capping) will provide a much more manageable and environmentally sound methods of dealing with the situation. Additionally, the second method encompasses many more known quantities than the first, and could provide a substantial cost savings to the Town. The Wappinger Town Board has authorized this firm to seek approval from your Department to perform Option #2 (i.e. in place capping of the additional area). The Contractor is close to finishing the clay cap as originally delineated, and would like to begin work on the additional area as soon as possible (i,e. by the week of June 15'h — 19e1). As such your prompt response would be greatly appreciated Any questions or comments may be addressed to this office. Thank you for your consideration in this matter. Very truly yours, f Joseph E.

On August 7, 2003, Conrad Geoscience personnel measured the percentage of methane (C114), percentage of the lower explosive limit (LEL), and percentage of oxygen (OZ) from 12 gas vents around the perimeter of the landfill. Measurements were also collected in and around nearby structures. Sampling was conducted in accordance with the approved procedure for landfill gas monitoring. Measurements were taken within the vents, and above and beneath the opening of these vents if methane was detected inside. Of the 12 vent Iocations monitored, four locations (GV -1, GV -2, GV -7, GV -8) had detectable concentrations of methane within the gas vent. GV -7 had detectable concentrations of methane above the vent pipe (above 100% LEL), LEL readings in the on-site building and gazebo were 0.0%. Data from all gas monitoring points are presented in the attached table. Landfill gas monitoring for the fourth quarter of 2003 has been tentatively scheduled for November.

FIELD ACTIVITIES On August 7, 2003, Conrad Geoscience personnel visited the site to conduct quarterly groundwater sampling. Samples were to be analyzed for routine water quality parameters as defined by 6 NYCRR Part 360-2.11(d)(6). Two on-site monitoring wells and a supply well were sampled and analyzed: PMW-8R, PMW-9, and SW -1. Monitoring Well PMW-8R is a 27' deep down -gradient monitoring well utilized to sample the unconsolidated sediment aquifer. PMW-9 is a 59.6' deep down gradient monitoring well utilized to sample the bedrock aquifer. SW -1 is an up gradient well used to supply water to the on-site facilities. Prior to sampling, static water level elevations were measured in each of the stipulated monitoring wells (PMW-8R, PMW-9). Well volumes for each well were calculated. Groundwater from Monitoring Well PMW-8R and PMW-9 were purged until all physical water quality parameters had stabilized. Samples were collected from Monitoring Wells PMW-8R and PMW-9 using dedicated polyethylene bailers and shipped to York Analytical Laboratories for analysis of routine parameters as defined by part 6 NYCRR Part 360-2.11(d)(6). Castle Point Landfill Groundwater Monitoring File ## CW000100 August 27, 2003 Page 2 RESULTS Monitoring Well PMW-8R The following metals exceed NYSDEC standards in PMW-8R: Iron (49.5 ppm), lead (0.071 ppm), magnesium (72.1 ppm) and manganese (8.96 ppm). Other inorganic parameters exceeding NYSDEC standards include sodium (36.4 ppm), total hardness (1250 ppm), and total dissolved solids (607 ppm), and total organic carbon (8.Oppm). All results are presented in the attached table (analytical report appended). No other inorganic parameters exceed NYSDEC standards. Monitoring Well PMW-9 The following metals exceed NYSDEC standards in PMW-9: Iron (9.17 ppm) and manganese (0.309 ppm). All results are presented in the attached table. No other inorganic parameters exceed NYSDEC standards. Supply Well SW -1 The following metals exceed NYSDOH standards in SW -1: Iron (0.607 ppm). Analytical reports are appended. Sampling for the 4th quarter of 2003 is tentatively scheduled for November 2003. If you have any questions, please do not hesitate to call.. Sincerely, CO,7D GEOSCIENCE CORP. Christopher B.

On February 27, 2003, Conrad Geoscience personnel measured the percentage of methane (CH4), percentage of the lower explosive limit (LEL), and percentage of oxygen (Oz) from 12 gas vents around the perimeter of the landfill. Measurements were also collected in and around nearby structures. Sampling was conducted in accordance with the approved procedure for landfill gas monitoring. Measurements were taken within the vents, and above and beneath the opening of these vents if methane was detected inside. Of the 12 vent locations monitored, only one location (GV -17) had detectable concentrations of methane within the gas vent (20% of the LEL). • No vents had detectable concentrations of methane above or below the vent pipe. • LEL readings in the on-site building and gazebo were 0.0%.

FIELD ACTIVITIES i' On February 27, 2003, Conrad Geoscience personnel visited the site to conduct quarterly groundwater sampling. Samples were to be analyzed for routine water quality parameters as defined by 6 NYCRR Part 360-2.11(d)(6). Two on-site monitoring wells were sampled and analyzed: PMW-8R, PMW-9. The on-site supply well was turned off for the winter months and therefore was not sampled at this time. Monitoring Well PMW-8R is a 27' deep down gradient monitoring well utilized to sample the unconsolidated sediment aquifer. PMW-9 is a 59.6' deep down gradient monitoring well utilized to sample the bedrock aquifer. SW -1 is an up gradient well used to supply water to the on-site facilities. Prior to sampling, static water level elevations were measured in each of the stipulated monitoring wells (PMW-8R, PMW-9). Well volumes for each well were calculated. Groundwater from Monitoring Well PMW-SR and PMW-9 were purged until all physical water quality parameters had stabilized. Samples were collected from Monitoring Wells PMW-8R and PMW-9 using dedicated polyethylene bailers and shipped to York Analytical Laboratories for analysis of routine parameters as defined by part 6 NYCRR Part 360-2.11(d)(6). Castle Point Landfill File # CW000100 March 18, 2003 Page 2 RESULTS Monitoring Well PMW-8R The following metals exceed NYSDEC standards in PMW-8R: Iron (1.19 ppb), magnesium (47.0 ppb) and manganese (4.24 ppb). Total Organic Carbon (7.5 ppb) exceeds NYSDEC standards. Other inorganic parameters exceeding NYSDEC standards include sodium (33.2 ppb), total hardness (589 ppb), and total dissolved solids (730 ppb). All results are presented in the attached table (analytical report appended). No other inorganic parameters exceed NYSDEC standards.

FIELD ACTIVITIES On August 27, 2002, Conrad Geoscience personnel visited the site to conduct quarterly groundwater sampling. Samples were to be analyzed for routine water quality parameters as defined by 6 NYCRR Part 360-2.11(d)(6). Two on-site monitoring wells and the on-site supply well were sampled and analyzed; PMW-8R, PMW-9, and SW -1. Monitoring Well PMW-8R is a 27' deep down -gradient monitoring well utilized to sample the unconsolidated sediment aquifer. PMW-9 is a 59.6' deep down -gradient monitoring well utilized to sample the bedrock aquifer. SW -1 is an up -gradient well used to supply water to the on-site facilities. Prior to sampling, static water level elevations were measured in each of the stipulated monitoring wells (PMW-8R, PMW-9). Well volumes for each well were calculated. Groundwater was purged from Monitoring Well PMW-9 until all physical water quality parameters had stabilized. Monitoring Well PMW-8R was purged dry to ensure sampling of representative formational water. Samples were collected from Monitoring Wells PMW-8R and PMW-9 using dedicated polyethylene bailers and shipped to York Analytical Laboratories for analysis of routine parameters as defined by part 6 NYCRR Part 360-2.11(d)(6). Samples were collected from the onsite supply well, SW -1, via the spigot inside the onsite supply shed. Castle Point Landfill File # CW000100 October 17, 2002 Page 2 VIR&IIiJV Monitoring Well PMW-SR The following metals exceed NYSDEC standards in PMW-8R: Iron, Magnesium, Manganese, and Sodium. Total Dissolved Solids, Total Hardness, and Total Organic Carbon also exceed NYSDEC standards. All results are presented in the attached table. No other inorganic parameters exceed NYSDEC standards. Monitoring Well PMW-9 The following metals exceed NYSDEC standards in PMW-9: Iron and Sodium. All results are presented in the attached table. No other inorganic parameters exceed NYSDEC standards. Supply Well SW -1 No inorganic parameters exceed the NYSDEC standards in SW -1. Results are presented in the attached table. Analytical reports are appended. Sampling for the 4th Quarter of 2002 is tentatively scheduled for November 2002. If you have any questions, please do not hesitate to call. Sincerely, CON . GEOSCIENCE CORP. z-� Christopher B.

FIELD ACTIVITIES On January 16, 2002, Conrad Geoscience personnel visited the site to conduct quarterly groundwater sampling. Samples were to be analyzed for routine water quality parameters as defined by 6 NYCRR Part 360-2.11(d)(6). Two on-site monitoring wells and the on-site supply well were to be sampled and analyzed; PMW-8R, PMW-9, and SW -1. Monitoring Well PMW-8R is a 27' deep down -gradient monitoring well utilized to sample the unconsolidated sediment aquifer. PMW-9 is a 59.6' deep down -gradient monitoring well utilized to sample the bedrock aquifer. SW -1 is an up -gradient well used to supply water to the on-site facilities. Samples from monitoring well PMW-8R and supply well SW -1 were not collected for this round. Monitoring well PMW-8R, once purged, did not produce a sufficient volume of water for sampling. Supply well SW -1 is turned off during the winter months. Prior to sampling, static water level elevations were measured in each of the stipulated monitoring wells (PMW-8R, PMW-9). Well volumes for each well were calculated. Groundwater was purged from Monitoring Well PMW-9 until all physical water quality parameters had stabilized. Samples were collected from Monitoring Well PMW-9 using a dedicated polyethylene bailer and shipped to York Analytical Laboratories for analysis of routine . parameters as defined by part 6 NYCRR Part 360-2.11(d)(6).

FIELD ACTIVITIES On August 14, 2001, Conrad Geoscience personnel visited the site to conduct quarterly groundwater sampling. Samples were to be analyzed for routine water quality parameters as defined by 6 NYCRR Part 360-2.1 l (d)(6). Two on-site monitoring wells and the onsite supply well were to be sampled and analyzed; PMW-8R, PMW-9 and SW -1. Monitoring Well PMW-8R is a 27' deep down -gradient monitoring well utilized to sample the unconsolidated sediment aquifer. PMW-9 is a 59.6' deep down -gradient monitoring well utilized to sample the bedrock aquifer. SW -1 is an up -gradient well used to supply water to the on-site facilities. Prior to sampling, static water level elevations were measured in each of the stipulated monitoring wells (PMW-8R, PMW-9). Well volumes for each well were calculated, Monitoring Well PMW-8R was purged dry and did not recharge to allow for sampling. Groundwater was purged from Monitoring Well PMW-9 until all physical water quality parameters had stabilized; purging data is summarized on the attached sampling sheets. Samples were collected from Monitoring Well MW -9 using a dedicated polyethylene bailer and shipped to York Analytical Laboratories for analysis of routine parameters as defined by part 6 NYCRR Part 360-2.11(d)(6).

On June 22, 2001, Conrad Geoscience personnel measured the percentage of methane (CH4), percentage of the lower explosive limit (LEL), and percentage of oxygen (OZ) from 15 gas vents around the perimeter of the landfill. Measurements were also collected in and around nearby structures. Sampling was conducted in accordance with the approved procedure for landfill gas monitoring. Measurements were taken within the vents, and above and beneath the opening of these vents if methane was detected inside. Of the 15 vent locations monitored, none had detectable concentrations of methane above the vent pipe. Nine vents had detectable concentrations of methane within the gas vent. Five of these vents exhibited values in excess of 25% of the LEL (GV -1, GV-8,'GV-17, GV -4, and GV -3). Each of these locations also had detectable concentrations of methane at the vent opening. 0 LEL readings in the on-site building and gazebo were 0.0%.

FIELD ACTIVITIES On April 3, 2001 Conrad Geoscience personnel visited the site to conduct quarterly groundwater sampling. Samples were to be analyzed for routine water quality parameters as defined by 6 NYCRR Part 360-2.1 l(d)(6). Three on-site monitoring wells were to be sampled and analyzed; PMW-8, PMW-9, and SW -1. Monitoring well PMW-8R is a 27' deep down -gradient monitoring well utilized to sample the unconsolidated sediment aquifer. PMW-9 is a 59.6' deep down -gradient monitoring well utilized to sample the bedrock aquifer. SW -1 is an up -gradient well used to supply water to the onsite facilities, Samples from supply well SW -1 were not collected for this round. This well is turned off during the winter months. Prior to sampling, static water level elevations were measured in each of the stipulated monitoring wells (PMW-8R, PMW-9). Well volumes for each well were calculated and CGC personnel purged three well volumes from PMW-8R before sampling to ensure sampling of representative formation water. Groundwater was purged from PMW-9 until all physical water quality parameters had stabilized. Physical water quality parameters were monitored for both wells during purging and are summarized on the attached sampling sheets. Samples were collected from Monitoring Well MW -9 and Monitoring Well MW -8R using dedicated polyethylene bailers and shipped to York Analytical Laboratories for analysis of routine parameters as defined by part 6 NYCRR Part 360-2.11(d)(6).

On December 20, 2000, Conrad Geoscience personnel measured the percentage of methane (CHQ), percentage of the lower explosive limit (LEL), and percentage of oxygen (02) from 14 gas vents around the perimeter of the landfill (See attached site map). Measurements were also collected in and around nearby structures. Sampling was conducted in accordance with the approved procedure for landfill gas monitoring. Measurements were taken within the vents, and above and beneath the opening of these vents if methane was detected inside. Of the 14 vent locations monitored, none had detectable concentrations of methane above the vent pipe. Three vents had detectable concentrations of methane within the gas vent. Two of these vents exhibited values in excess of 25% of the LEL (GV -17 and GV -8). Each of these locations had detectable concentrations of methane at the vent opening. 11&ioalc\My ➢ocumentsTonrad Gooseience1CW600I Oftandril!

Smith, Supervisor Reference: Castlepoint Landfill Dear Supervisor Smith & Board Members: HECEIVED TU L 13 2090 ELAINE SNOWDEN "rOWN CL IK You are aware from our May 31", 2000 correspondence regarding the Castlepoint Landfill of the fact that methane gas was escaping through the landfill vents. We recommended that the Town retain a specialist in analyzing this condition and make a complete assessment of any potential safety hazards with respect to the landfill. Field Safety Corporation was retained for that purpose and has filed a report dated June 14`", 2000. 1 have enclosed a copy of that report for your review. In their report, Michael Ziskin of Field Safety Corp., makes some recommendations regarding the landfill and some recommendations regarding establishing a uniform protocol for future gas monitoring. It is our opinion that their recommendation listed on Page 1 of their letter, including items 1 through 6, be completed as quickly as possibly, and that Conrad Geoscience, who is doing the monitoring of the landfill on a quarterly basis, utilize the protocol established in No. 7 on Page 2 of the same letter. As you can see, the test results obtained by Mr. Ziskin were in conformance with the test results obtained by Conrad Geoscience during their quarterly and subsequent monitoring. Most important is the fact that in the bathroom and gazebo, methane was not detected. I have also enclosed in your packet a correspondence history regarding the above, including the second round of testing done by Conrad Geoscience and transmitted to us on May 31 ", 2000. Then gas samples taken approximately 1' away from these vents exhibited no detection of methane. I am taking the liberty of copying Stave Capowski, the interim Director of the Dutchess County Health Department, of all these results, Andrew Lent of the New York State Department of Environmental Conservation, and Ralph Holt, Chairman of Recreation Committee. joeph E.

While collecting water samples, Conrad representatives discovered that the 2" PVC casing in one of the shallow, overburden wells (MW -8) had been damaged, and could not be sampled. The source of the damage is not readily apparent, but could have been the result of previous construction activities, ground settlement, vandalism, etc. Conrad Geoscience Corp. has estimated that it will cost $2975.00 to reinstall and develop the well. It should be rioted that this well had been targeted by the NYSDEC to be part of the ongoing post closure monitoring program Please advise this office as to how you would like us to proceed in the matter Any questions or comments may be addressed to this office.

I have attached copies of the above for your review. It should be noted in the May 23rd, 2000 letter from Conrad Geoscience that they acknowledge the fact that the methane that normally builds up in the landfill is escaping from beneath the landfill cap through the vent pipes as designed. They agree that we should move recreational activities farther away from the vents, and make a more complete assessment of any potential safety hazards. They had given us the name of Michael Ziskin of Field Safety Corporation to contact. I subsequently received a proposal from Mr. Ziskin on May 30th, 2000, and have had a number of telephone conversations with him. I have asked Mr. Ziskin to proceed with the initial consultation and, as matter of fact, this if being done on June 1 `t, 2000. will keep the Board appraised of our progress. Joseph E.

Smith - 2 - May 31, 2000 Town Board Re: Castlepoint Landfill With respect to the May 31s', 2000 correspondence from Conrad Geoscience. I had asked them to run an additional run of air sampling on the vents. As you can see from this round of sampling, three (3) of the sixteen (16) gas vents exhibited results in excess of 25% of lower explosive limit (LEL) [as compared to four (4) last time], but samples taken approximately 1' away from these vents exhibited no detection of methane. It should also be noted that samples taken in the building and the gazebo existing on the site, exhibited a 0% concentration of methane, and therefore no percentage of LEL. We are following up on this as quickly and completely as possible, and will keep the Board Members and Recreation Commission appraised of our progress. If there are any questions in the interim, please do not hesitate to contact me at the office. Very truly yours, Joseph E. Paggi, Jr., P.E. JEP:law Enclosure cc: Hon. Vincent Bettina, Councilman Hon.

We agree that recreation activities should be moved to an area farther from the vents until a more complete assessment of potential hazards can be made. Foe those vents at which methane exceeded the lower explosive limit (LEL), rive recommend that further evaluation be completed by a safety professional trained and equipped to determine whether a potential fire or explosion hazard exists at those points givers the proximity to foot traffic and other activities. In the past, we have contracted with firms such as Field Safety Corp. to conduct such evaluations. I spoke with Michael Ziskin of Field Safety Corp.

As noted, four (4) of the seventeen (17) gas vents exhibited a value in excess of 25% of the lower explosive limit (LEC). It is our opinion at this point in time that the following should occur: 1. The Town should retain the services of a qualified firm to assess the potential hazard for this gas vent discharge. We have taken the liberty of speaking about this with John Conrad of Conrad Geoscience, the firm that the Town retained to perform the quarterly monitoring. They will be obtaining the name of a firm that can provide the necessary services to the Town. 2. In any event, the southerly playground site should be moved to the extreme northwest corner of the site to obtain the maximum distance from the landfill. 3. The safety expert retained by the Town should render an opinion on the appropriateness of the recreation use of this site with respect to the summer program and the softball fields in the extreme east side of the site. 4. The gas monitoring should be done on a quarterly basis as originally accepted by the Town Board. Joseph E. Paggi, Jr., P.E. Ernst Martin, Jr., P.E., L.S. Cherles R, Del Bcne, Jr., P.E. Constance O.

PROPOSED DEED REVISIONS: The deed for the Castlepoint Landfill was revised to indicate: • The general period of time during which the site was utilized as a landfill (1972-1987). • While an exact description of the wastes contained within the site is unknown, a general statement was included indicating that the Town of Wappinger utilized the site to dispose of items from individual residences that were collected during Spring cleanup operations and yard wastes. Available information from Town of Wappinger Highway Department personnel indicates that metals and tires were separated during these cleanup operations, and removed from the site for disposal elsewhere. Test pits excavated by the Town prior to and during landfill closure operations revealed wastes consistent in nature with such cleanup operations. • All existing records of the facility including all subsurface investigation and test results have been filed with the N.Y.S.D.E.C. This is noted in the deed. • The deed includes a map which was also filed with the Dutchess County Clerk's Office which clearly indicates the limits of the landfilled areas within the property boundary. e The deed also indicates that the use of the site is restricted pursuant to the provisions of 6NYCRR Part 360-2.15(k)(9). • A copy of said property deed is enclosed under Section "N" herein. -2- C. FUTURE USE OF THE PROPERTY: While the un -landfilled portions of the subject property shall continue to be utilized by the Town of Wappinger for community recreation purposes, the landfilled areas shall be subject to a more restrictive proposed post -closure use. The Town of Wappinger intends to implement restrictions to the landfilled area as detailed in the following June 140', 2000 correspondence from Field Safety Corp. (See Pages 3A and 3B). Please note that the existing playground area has already been relocated off the landfill mass. Use of the property shall not disturb the integrity of the final cover, liners, or any other components of the containment systems, or the function of the monitoring or environmental control systems, unless necessary to comply with the requirements of Section 360-2.20 of 6 NYCRR Part 360. The N.Y.S.D.E.C. must approve any disturbance and will do so only if the Town of Wappinger demonstrates that disturbance of the final cover, liners or other component of the containment system, will not increase the potential threat to human health or the environment. -3- FIELD SAFETY CORPORATION Compliance and Beyond... Through Services and Education June 14, 2000 Mr, Joseph Paggi, Jr., P.E. Paggi, Martin, & Del Bene LLP 56 Main Street Poughkeepsie, NY 12601 Dear Mr. Paggi: On June 1, 2000, Field Safety Corporation (FSC) performed an on site assessment and at the Castlepoint Landfill, in the Town of Wappinger, New York. The scope of this service was to perform an initial site evaluation of the landfill venting system with regard to public safety. The site evaluation was conducted by Mr. Michael H. Ziskin, CHCM, C MM of Field Safety Corporation. Mr, Joseph Paggi, Jr., P.E. of PAGGI, MARTIN & DEL BENE LLP provided Mr. Ziskin with site specific information. The site evaluation consisted of a review of background information including site maps, the final Post - Closure Monitoring and Maintenance Manual, gas monitoring reports from Conrad Geoscience Corp., and a survey of the landfill venting system. The survey of the landfill venting system included a site walk over and gas monitoring. The gas monitoring involved measuring gas venting temperature, carbon dioxide, carbon monoxide, percent relative humidity, volatile organic compounds and combustible gases. The site walk over and the results from the gas monitoring provided information to support the following recommendations: 1. Relocate the playground from within the landfill boundary (preferably to the opposite side of the park roadway; 2. Restrict all pedestrian and vehicular activity from within the landfill boundary 3. Identify all authorized activities within the landfill boundary; 4, Maintain the integrity of the landfill venting system by securing the landfill perimeter with .fencing. 5. Establish setback criteria - from the landfill vents closest to the perimeter of the landfill and the fence line (for the installation of the fence around the perimeter of the landfill), 6. Identify each landfill vent with a corresponding marking. 101 C Fowler Road, North Branford, CT 06471 s In CT (888) 964-9199 • PH (203) 483-6003 + FAX (203) 483-6009 Suite 101, 579 Lake Dr., Guilford, CT 06437 • In Cr (888) 964-9199 • PH (203) 457-2100 • FAX (203) 457-2109 An Equal Opportunity Employer S—A 7. Maintain gas monitoring utilizing a protocol to establish uniformity, consistency and duality control. This protocol should specify: • calibration requirement for gas measurement instrumentation; • landfill vents to be measured; • exact location where the measurements at each vent are to be taken; • parameters to be measured at each landfill vent; • atmospheric and environmental conditions at the time measurements are taken; • visual inspection of landfill vents and perimeter fence integrity; and • periodic review of the gas monitoring results. A copy of FSC's gas measurement results and photographs showing the landfill venting system are attached, If you have any questions regarding this report, please feel free to call me. I look forward to meeting with you to prioritize and plan the implementation of the above recommendations. Very truly yours, Michael H. Ziskin, CHCM, CHMM Executive Vice President S-5 D. SURFACE DRAINAGE: Final surface slopes range from a minimum of 4% to a maximum of 33% to promote surface runoff while maintaining slope integrity. Interceptor swales have been installed upgradient of the landfill mass to prevent surface waters from draining across the top of the landfill surface. Said interceptor swales shall be maintained so as to operate continuously and effectively. The gentle slopes and the grass cover will minimize soil erosion from both wind and rainfall. In addition, quarterly visual inspections of the site will be performed to determine if any erosion has taken place. Upon identification, the necessary remedial erosion control measures will be undertaken. Said quarterly inspections shall be performed by Town of Wappinger personnel, or their designated representatives, and the results submitted to the N.Y. S.D.E. C. as part of the annual inspection report. -4- E. SOIL COVER SYSTEM: The grass vegetative cover overlying the soil cap will be the primary means of maintaining the integrity of the cap system. Quarterly inspections will determine if any slumping or subsidence in the soil cover has occurred. Any changes of an unnatural degree that may occur in the vegetative cover, any ponding of rainwater on the surface, and any apparent observation of leachate outcropping to the surface, any signs of soil erosion such as channeling shall be noted on the quarterly inspection report forms. In addition, the vegetative cover shall be maintained so as to prevent shrubs and saplings from growing on the landfill cap and penetrating the cover. Said quarterly inspections shall be performed by Town of Wappinger personnel, or their designated representatives, and the results submitted to the N.Y.S.D.E.C. as part of the annual inspection report. -5- F. VECTOR ABATEMENT; The primary method of vector control shall be through the installation of the soil cap and topsoil cover. Secondarily, post -closure quarterly visual inspections shall be conducted over the minimum post -closure period to identify the presence of any vectors which may inhabit the landfill including, but not limited to, rodents, insects, and birds. Should vectors be discovered they shall be removed in a manner consistent with the N.Y.S.D.E.C. and other recommended guidelines. Town of Wappinger personnel or their designated representatives shall be responsible for conducting the quarterly visual inspections and for implementing any necessary vector control measures. The results shall be submitted to the N.Y. S.D.E.C. as part of the Annual Inspection Report. The site inspector shall observe any holes made by burrowing animals or other evidence of the presence of vectors. If the landfill soil cap has been found to be damaged it shall be restored to its original specification. Should the landfill require any additional treatment for rodents, birds, or insect control, Region 3 N.Y.S.D.E.C. personnel, specifically the Pesticide Officer, shall be contacted to approve any proposed extermination method prior to its implementation. G. GAS MONITORING: A soil gas survey was conducted at the Castle Point Landfill on February 13" and February 15th, 1996. Four soil gas points (GM -1 through GM -4 and one monitoring well (PMW-8) were field tested for volatile organic vapors, methane, and explosive gases. The soil gas points were constructed with '/Z inch or 2" (I.D.) PVC casing sealed at the top with a rubber stopper. A plastic hose connector was inserted through a hole in the rubber stopper and connected to a peristaltic pump via a length of silicon tubing. A rubber stopper assembly was also connected to the other end of the tubing at the discharge. The peristaltic pump was used to draw air from the soil gas installation through the silicon tubing. Air discharging from the soil gas installation was monitored for organic vapors with an Hnu photoionization detector and for methane, % LEL and 02 with a GasTech Meter. To obtain reading from Well PMW-8, a 2 inch rubber cap equipped with a brass hose connector was fitted on the well. Air readings were monitored by the same procedures. Results: Volatile, organic vapor levels were slightly above background levels. Readings ranged from 0.1 to 0.7 Hnu units. • There were no detectable readings for % LEL or % gas (Methane) • 02 levels ranges from 8.75% to 21% A minimum of four gas vents per acre were constructed in the landfill. Gas vent design meets the requirements of Part 360 except for depth penetration. Gas vents penetrate to a depth acceptable to the Department, but not less than six feet into the waste. -7- Post -closure explosive gas monitoring and maintenance shall be performed at least quarterly to insure that: a. Explosive gas levels do not exceed 25% of the lower explosive limit within any structures on or off the site (except gas control or recovery system components); And b. The level of subsurface explosive gas does not exceed the lower explosive limit anywhere along the property boundary. If monitoring shows these levels are exceeded, N.Y.S.D.E.C. shall be notified and remedial action, such as the construction of gas cut-off trenches, should be immediately taken. In addition, this quarterly explosive gas monitoring and maintenance shall assure that the gas vents are not blocked and that landfill gas has not damaged the final cover. Post -closure explosive gas monitoring shall include: subsurface monitoring along a perimeter outside the waste mass but within the property boundary; monitoring within all onsite and nearby structures; and inspection of the final cover and surrounding area. Perimeter subsurface monitoring shall be performed at maximum intervals of 100 feet if a portable explosive gas detector is used. Monitoring with a portable detector shall be performed when the ground surface has been wet or frozen for several days. Monitoring shall be done below the wet or frozen zone. If permanent gas monitoring wells are constructed for perimeter subsurface monitoring, they should be located at maximum 'intervals of 400 feet. Wells should be constructed to a depth of 75% of the maximum depth of the waste mass below the surrounding ground surface or to the seasonal low groundwater level, whichever is higher. The bottom 213 of the wells should be screened. In addition, post -closure monitoring and maintenance shall include regular inspection of the landfill final cover and surrounding area for cracks or stressed vegetation which might indicate the escape of landfill gas. Areas where there are cracks or where vegetation appears stressed shall be tested with a portable explosive gas detector. -8- Any areas of the final cover which may have been damaged should be repaired and steps shall be taken, such as the installation of additional gas vents, to prevent future damage. Areas around the waste mass where gas is found to be escaping shall be tested with a portable explosive gas detector to determine whether they indicate pathways by which explosive gas is migrating offsite. If so, additional measures shall be taken to prevent offsite migration. The percentage of explosive gas emanating from gas vents shall be measured to indicate the effectiveness of the gas vents. All gas monitoring shall be performed when the atmospheric pressure is low (below 29.92 inches of mercury). Atmospheric pressure shall be recorded along with the other monitoring results. If the landfill is on a property that is sufficiently large as to preclude offsite migration of landfill gas, then the perimeter explosive gas monitoring requirements are inapplicable. In order to qualify for omission of the perimeter monitoring requirements, the distance from the waste mass to the property boundary must be a minimum of 1,000 feet or adequate onsite barriers to gas migration must exist. A barrier to gas migration is either: a ravine or excavation with its base extending as deep as the base of the waster mass, or to very low permeability soils or seasonal low groundwater, or a surface water that has flow all year, and which is indicative of groundwater elevation. Said gas monitoring shall be performed by qualified professional firms on an individual contract basis with the Town of Wappinger subsequent to an informal bid process. Results shall be submitted to the N.Y.S.D.E.C. as part of the Annual Inspection Report. LandTll Gas Monitoring Protocol: The standard operating procedures for collecting and analyzing landfill decomposition gas data shall be in conformance with the following protocol (see Page 9A). WE LANDFILL GAS MONITORING PROCEDURES Castle Point Landfill, Wappingers Falls, New York Summarized below are the landfill gas monitoring procedures for the Castle Point Landfill, Wappingers Falls, New York. In accordance with 6NYCRR Part 360-2.15 (a)(2)(i - ii). The intent of this investigation is to identify the presence and concentration of explosive gases at or near the landfill, including at the property line, in all on-site structures, and in potentially impacted off-site structures and to determine the extent of actual or potential for gas migration off-site, • A GasTechGT201, or an equivalent instrument capable of monitoring %02, %Methane, and %LEL (lower explosive limit) is to be used. • The instrument is to be calibrated either in the field prior to sample collection or by the rental agency prior to shipment. • Monitoring points are the perimeter gas vents, the perimeter valves (314" PVC pipes), the gazebo, and the bathroom, as depicted on the Paggi & Martin, 1990 Landfill Closure "As - Built" diagrams. • Gas samples are to be collected from. approximately 2 feet above each gas vent and within each vent at the apex of each PVC riser. Samples are to be collected for 30 seconds at each location. If positive readings are detected inside the vent, a reading will be taken from the vent opening. • Samples in the gazebo are to be collected from beneath the roof in the rafters. • Samples collected in the bathroom are to be taken near the ceiling. • All gas monitoring is to be performed when the atmospheric pressure is below 29.92 inches of mercury • Barometric pressure should be recorded in table format in the field along with the other monitoring results, �-A r� CONAL+w Gizos TT,,NCaS Com). L � _mil H. GROUNDWATER MONITORING: The Town of Wappinger upgraded specific aspects of it's initial Landfill Closure Plan to comply with the Part 360 regulations effective December 31, 1988 in an effort to secure State Assistance under the Environmental Quality Bond Act (EQBA). Part of this upgrade included installation of two (2) monitoring wells downgradient of the landfill in an effort to reduce future environmental monitoring costs. This reduction in the sampling requirements was detailed in a March 22"d, 1995 correspondence from Alan A. Fuchs, Solid Waste Engineer — Region 3 to Supervisor Constance O. Smith, which indicated: "The N.Y.SD.E.0 is willing to reduce the landfill's water quality sampling requirements if two monitoring wells are added to the monitoring network which are clearly capable of detecting the landfill's water quality impact. The proposed water -quality monitoring reduction is to decrease the required number of sampling locations per sampling event from five to three monitoring wells The proposed program would include two monitoring wells downgradient of the landfill and one upgradient monitoring location. " The Town proposes to perform annual baseline and quarterly routine monitoring of downgradient wells PMW-8 and PMW-9 and the existing upgradient production well as indicated on the "As -Built" Plan. Said sampling schedule would be conducted at this frequency until a minimum of ten (10) rounds of test results are collected. After that time, and depending on the results obtained, the Town of Wappinger may request that the N.Y.S.D.E.C. modify the sampling and analysis requirements pursuant to the Local Government Regulatory Relief/Initiative as follows: Specific Variance. Post Closure Monitoring I: The frequency of post -closure groundwater, surface water and leachate monitoring required by 6 NYCRR Part 360-2.15(i)(4) may be reduced from annually for baseline parameters and quarterly for routine parameters to annually for routine parameters and once every five years for baseline parameters [See 6 NYCRR Part 360-2.11(c) (6)]. Siam Guidance: This means that the frequency and cost of post -closure testing for contamination would be significantly reduced_ In order to qualify for this variance, all of the following conditions should be met. 1. Contamination, except for leachate indicators, in down -gradient groundwater monitoring wells does not exceed the groundwater standard or background level, whichever is higher, for any contaminant. 2. The landfill is closed and maintained such that no surface leachate is allowed to discharge from the facility; and, 3. There is no contamination of surface waters once cap construction is complete. 4. The landfill should not be located over a sole source or primary aquifer. Based on the post -closure monitoring results, N.Y. S.D.E. C. may require more frequent monitoring at a later time. Said water quality monitoring shall be performed by qualified professional firms on an individual contract basis with the Town of Wappinger subsequent to an informal bid process. Results shall be submitted to the N.Y.S.D.E.C, as part of the Annual Inspection Report, Baseline and routine test parameters are outlined on pages 12 — 19 herein: Monitoring well MW -8 was damaged prior to the April 2000 water quality monitoring event. The well was replaced by Well MW -8R, installed by General Borings, Inc. under the supervision of Conrad Geoscience Corp. The Monitoring Well Installation Detail and Boring Log are attached hereto as pages ll -A and 11-B. Existing Monitor Well MW -8 was abandoned in conformance with N.Y.S.D.E.C. well decommissioning standards as follows: the steel surface (protective) casing was removed, the subsurface PVC riser pipe was split, and the well was pressure grouted from the bottom up to dissipate water and fill all voids. - 11- as.r.itr+ru iir, .,x r'n:z ai44.rcu:.S,lallQ;J13UL MONITOR, 11 INSTALLATION DETAIL FOR WELL IN UNCONSO-LIDATED DEPOSIT CfttLLsq:, , Erik DelFrjore BODING W, t PMW-86 GBl tog mo.: 180-00 TOP Or CAS I tvcx EL, :il.ltiF+4CE EL.

LEACHATE COLLECTION SYSTEM: Leachate control systems have not been designed as part of this landfill closure plan. The soil cap will prevent rainwater from infiltrating into the landfill mass, thus restricting potential leachate development. The grading of the site, as discussed in previous sections, will encourage surface water to flow off the landfill mass and thus, prevent further leachate from forming. During the quarterly visual inspections, leachate outcropping will be looked for. If found, it will be immediately noted and proper engineering control measures (as approved by the N.Y.S.D.E.C.) shall be implemented. Said quarterly inspections shall be performed by Town of Wappinger personnel, or their designated representatives and the results submitted to the N.Y.S.D.E.C. as part of the Annual Inspection Report. -20- I RECORDKEEPING AND REPORTING: Quarterly visual inspections of the site will be conducted by Town personnel or their designated representatives for the minimum post closure period following completion of the landfill closure. These reports will be filed at the Town Hall. These inspections will include the soil cap and topsoil, venting system, site drainage, specifically any items such as subsidence of the soil cap, areas of the erosion, dead or dying vegetation, vandalism, and vectors will be reported immediately to Town personnel followed by taking of corrective action. In addition, qualified professional firms will be contracted with to perform quarterly and annual groundwater quality and gas monitoring following N.Y.S.D.E.C. protocols. An annual report will be submitted to N.Y.S.D.E.C. which contains an analysis of the groundwater quality sampling, gas monitoring and annual inspection report by the Town of Wappinger identifying results of the quarterly visual inspections, and any maintenance necessary during the year. Copies of all said information shall be available for inspection at the Town of Wappinger Town Hall. -21- K. RESOURCE REOUIItEMENTS: Quarterly visual inspections of the soil cap, vegetative cover, site drainage, venting system, areas of subsidence, erosion, dying vegetation, vandalism and vectors shall be performed by Town of Wappinger personnel or their designated representatives. The Town of Wappinger work force includes staff and equipment sufficient to perform this work. Quarterly water quality and gas monitoring shall be performed by qualified professional firms on an individual contract basis with the Town of Wappinger subsequent to an informal bid process. The names and contact numbers of said professional firms shall be provided to the N.Y. S.D.E. C. as they become available. -22- M. FINANCIAL ASSURANCE CRITERIA: The Town of Wappinger is in the process of securing bids for quarterly water quality and gas monitoring services as detailed herein, Upon final acceptance of a qualified professional firm, the estimated yearly costs to perform the prescribed work will be submitted to the N.Y.S.D.E.C. All other work will be performed on a force account basis by Town personnel. The Town of Wappinger owns and will continue to own the Castle Point Landfill site, and will be financially responsible for post -closure monitoring and maintenance. -24- DUTCHESS COUNTY CLERK RECORDING PAGE RECORD & RETURN TO: PAGGI MARTIN & DEL BENE 56 MAIN ST POUGHKEEPSIE NY 12601 RECEIVED FROM: PAGGI & MARTIN.

On October 2, 2000, Conrad Geoscience personnel measured the percentage of methane (CH4), percentage of the lower explosive limit (LEL), percentage of carbon dioxide (CO2), and percentage of oxygen(02)from 13 gas vents around the perimeter of the landfill (Figure 1). Measurements were also collected from within nearby structures. Sampling was conducted in accordance with the attached procedure for landfill gas monitoring, which should be appended to the PCMMP. Measurements were taken above the vents, within the vents and beneath the opening of these vents. • Of the 13 vent locations monitored none had detectable concentrations of methane above the vent pipe. • Four vents had detectable concentrations of methane within the gas vent. Three of these. vents exhibited values in excess of 25% of the LEL (GV -1, 7 and 8). Each of these locations had detectable concentrations of methane at the vent opening.

[fv� LANDFILL GAS MONITORING PROCEDURES Castle Point Landfill, Wappingers Falls, New York Summarized below are the landfill gas monitoring procedures for the Castle Point Landfill, Wappingers Falls, New York. In accordance with 6NYCR.R Part 360-2.15 (a)(2)(i - ii). The intent of this investigation is to identify the presence and concentration of explosive gases at or near the landfill, including at the property line, in all on-site structures, and in potentially impacted off-site structures and to determine the extent of actual or potential for gas migration off-site. • A GasTechGT201, or an equivalent instrument capable of monitoring %02i %Methane, and %LEL (lower explosive limit) is to be used. • The instrument is to be calibrated either in the field prior to sample collection or by the rental agency prior to shipment. • Monitoring points are the perimeter gas vents, the perimeter valves (314" PVC pipes), the gazebo; and the bathroom, as depicted on the Paggi & Martin, 1999 Landfill Closure "As - Built" diagrams. • Gas samples are to be collected from approximately 2 feet above each gas vent and within each vent at the apex of each PVC riser. Samples are to be collected for 30 seconds at each location. If positive readings are detected inside the vent, a reading will be taken from the vent opening. • Samples in the gazebo are to be collected from beneath the roof in the rafters. • Samples collected in the bathroom are to be taken near the ceiling. • All gas monitoring is to be performed when the atmospheric pressure is below 29.92 inches of mercury • Barometric pressure should be recorded in table format in the field along with the other monitoring results.

FIELD ACTIVITIES On April 26, 2000, Conrad Geoscience conducted quarterly groundwater sampling. Two on-site monitoring wells, PMW-8 and PMW-9, and the on-site supply well, SW -1, were scheduled for testing for 1993 baseline parameters as defined by 6 NYCRR Part 360-2.11(d)(6) and the USEPA Method 8021 STARS. Monitoring Well MW -8 is 25 feet deep, and is completed in the unconsolidated unit along the down -gradient perimeter of the landfill. Monitoring Well MW -9 is 59.6 feet deep, and is completed in bedrock along the down -gradient perimeter of the landfill. Supply Well SW -1 is an up -gradient bedrock well used to supply water to on-site facilities. Prior to sampling, static water level elevations were measured in each of the two monitoring wells (PMW-8, PMW-9). PMW-8 could not be sampled due to an obstruction approximately 3 feet below grade. Conrad Geoscience personnel purged between 3 and 5 well volumes prior to sample collection from PMW-9. Physical water quality parameters were monitored during purging and are summarized on the attached sampling sheet. Samples were collected from PMW-9 using a dedicated polyethylene bailer. Samples from SW -1 were collected from the tap located in the utility room of the on-site maintenance shed before the water softener. Water samples were shipped to Columbia Analytical Services for analysis of baseline parameters as defined by part 6 NYCRR Part 360-2.11(d)(6) and USEPA Method 8021 STARS. RESULTS Water quality results are summarized below. All results are summarized in the attached tables, and excerpts from the analytical report are appended. A complete analytical report is on file with Conrad Geoscience.

Monitoring Well PMW-9 No volatile organic compounds (VOCs) were detected in samples collected from PMW-9. The following metals exceed NYSDEC groundwater standards in PMW-9: Iron, manganese, sodium and zinc. Two other inorganic parameters exceed the NYSDEC standard in PMW-9 (color and Total Organic Carbon.) Supply Well SW -1 No VOCs were detected in samples collected from SW -1. The following inorganic compounds exceed the NYSDEC groundwater standards in SW -1: Iron, magnesium, sodium and zinc. Of these, only iron and zinc exceed the NYSDOH drinking water standard. No other inorganics exceed the NYSDEC standard in SW -1. Re -installation of Monitoring Well PMW-8 is tentatively scheduled for September 2000.

The bids for these items were based on the specifications provided in the "Post -Closure Monitoring & Maintenance Manual," which was attached to your letter dated January 12, 2000. TLC's gas monitoring costs are based on the assumption that drive points will be installed at 100 -.Foot centers around the perimeter of the landfill. per NYSDEC specifications. Sampling costs could be greatly reduced if permanent gas monitoring wells are installed. Based on the documents provided, it was unclear if such monitoring wells exist.

Groundwater & Gas Monitoring Personnel These services will be performed by qualified professional firms on an individual contract basis with the Town of Wappinger subsequent to an informal bid process. Appropriate names and contact numbers shall be provided to the New York State Department of Environmental Conservation (NYSDEC) as they become available. -1- R PROPOSED DEED REVISIONS: The deed for the Castlepoint Landfill shall be revised to indicate: The general period of time during which the site was utilized as a landfill (197-198) • While an exact description of the wastes contained within the site is unknown, a general statement shall be included indicating that the Town of Wappinger utilized the site to dispose of items from individual residences that were collected during Spring cleanup operations and yard wastes. Available information from Town of Wappinger Highway Department personnel indicates that metals and tires were separated during these cleanup operations, and removed from the site for disposal elsewhere. Test pits excavated by the Town prior to and during landfill closure operations revealed wastes consistent in nature with such cleanup operations. All existing records of the facility including all subsurface investigation and test results have been filed with the N.Y.S.D.E.C. The deed must reference a map which shall be filed with the Dutchess County Clerk's Office which clearly indicates the limits of the landfilled areas within the property boundary. The deed must also indicate that the use of the site is restricted pursuant to the provisions of 6NYCRR Part 360-2.15(k)(9). -2- C, FUTURE USE OF THE PROPERTY: Subsequent land use of the landfill area by the Town of Wappinger shall be in the form of community recreation. The site is designated for predominately passive recreation activities, but also has provisions for playground activities, children's summer camp, softball, etc. Use of the property shall not disturb the integrity of the final cover, liners, or any other components of the containment systems, or the function of the monitoring or environmental control systems, unless necessary to comply with the requirements of Section 360-2.20 of 6 NYCRR Part 360, The N.Y.&D.E.C. must approve any disturbance and will do so only if the Town of Wappinger demonstrates that disturbance of the final cover, liners or other component of the containment system, will not increase the potential threat to human health or the environment. -3- D. SURFACE DRAINAGE; Final surface slopes range from a minimum of 4% to a maximum of 33% to promote surface runoff while maintaining slope integrity, Interceptor swales have been installed upgradient of the landfill mass to prevent surface waters from draining across the top of the landfill surface. Said interceptor swales shall be maintained so as to operate continuously and effectively. The gentle slopes and the grass cover will minimize soil erosion from both wind and rainfall. In addition, quarterly visual inspections of the site will be performed to determine if any erosion has taken place. Upon identification, the necessary remedial erosion control measures will be undertaken. Said quarterly inspections shall be performed by Town of Wappinger personnel, or their designated representatives, and the results submitted to the NX.S.D.E.C. as part of the annual inspection report. E. SOIL COVER SYSTEM: The grass vegetative cover overlying the soil cap will be the primary means of maintaining the integrity of the cap system. Quarterly inspections will determine if any slumping or subsidence in the soil cover has occurred. Any changes of an unnatural degree that may occur in the vegetative cover, any ponding of rainwater on the surface, and any apparent observation of leachate outcropping to the surface, any signs of soil erosion such as channeling shall be noted on the quarterly inspection report forms, In addition, the vegetative cover shall be maintained so as to prevent shrubs and saplings from growing on the landfill cap and penetrating the cover. Said quarterly inspections shall be performed by Town of Wappinger personnel, or their designated representatives, and the results submitted to the N.Y.S.D.E.C, as part of the annual inspection report. -S- F VECTOR ABATEMENT: The primary method of vector control shall be through the installation of the soil cap and topsoil cover, Secondarily, post -closure quarterly visual inspections shall be conducted over the minimum post -closure period to identify the presence of any vectors which may inhabit the landfill including, but not limited to, rodents, insects, and birds. Should vectors be discovered they shall be removed in a manner consistent with the N. Y.S.D.E.C. and other recommended guidelines. Town of Wappinger personnel or their designated representatives shall be responsible for conducting the quarterly visual inspections and for implementing any necessary vector control measures. The results shall be submitted to the N.Y.S.D,E,C. as part of the Annual Inspection Report. The site inspector shall observe any holes made by burrowing animals or other evidence of the presence of vectors, If the landfill soil cap has been found to be damaged it shall be restored to its original specification. Should the landfill require any additional treatment for rodents, birds, or insect control, Region 3 N.Y.S,D.E.C. personnel, specifically the Pesticide Officer, shall be contacted to approve any proposed extermination method prior to its implementation. G. GAS MONITORING: A soil gas survey was conducted at the Castle Point Landfill on February 13`' and February 15"', 1996, Four soil gas points (GM -1 through GM -4_ and one monitoring well (PMW-8) were field tested for volatile organic vapors, methane, and explosive gases. The soil gas points were constructed with 1/2 inch or 2" (ID.) PVC casing sealed at the top with a rubber stopper. A plastic hose connector was inserted through a hole in the rubber stopper and connected to a peristaltic pump via a length of silicon tubing. A rubber stopper assembly was also connected to the other end of the tubing at the discharge, The peristaltic pump was used to draw air from the soil gas installation through the silicon tubing. Air discharging from the soil gas installation was monitored for organic vapors with an Hnu photoionization detector and for methane, % LEL and 02 with a GasTech Meter. To obtain reading from Well PMW-8, a 2 inch rubber cap equipped with a brass hose connector was fitted on the well. Air readings were monitored by the same procedures. Results: • Volatile, organic vapor levels were slightly above background levels. Readings ranged from 0.1 to 0.7 Hnu units. • There were no detectable readings .for % LEL or % gas (Methane) 02 levels ranges from 8.75% to 21% A minimum of four gas vents per acre were constructed in the landfill. Gas vent design meets the requirements of Part 360 except for depth penetration. Gas vents penetrate to a depth acceptable to the Department, but not less than six feet into the waste. -7- Post -closure explosive gas monitoring and maintenance shall be performed at least quarterly to insure that: a. Explosive gas levels do not exceed 25% of the lower explosive limit within any structures on or off the site (except gas control or recovery system components); And b. The level of subsurface explosive gas does not exceed the lower explosive limit anywhere along the property boundary. If monitoring shows these levels are exceeded, N.Y.&D.E.C. shall be notified and remedial action, such as the construction of gas cut-off trenches, should be immediately taken. In addition, this quarterly explosive gas monitoring and maintenance shall assure that the gas vents are not blocked and that landfill gas has not damaged the final cover. Post -closure explosive gas monitoring shall include: subsurface monitoring along a perimeter outside the waste mass but within the property boundary; monitoring within all onsite and nearby structures; and inspection of the final cover and surrounding area. Perimeter subsurface monitoring shall be performed at maximum intervals of 100 feet if a portable explosive gas detector is used. Monitoring with a portable detector shall be performed when the ground surface has been wet or frozen for several days. Monitoring shall be done below the wet or frozen zone. If permanent gas monitoring wells are constructed for perimeter subsurface monitoring, they should be located at maximum intervals of 400 feet. Wells should be constructed to a depth of 75% of the maximum depth of the waste mass below the surrounding ground surface or to the seasonal low groundwater level, whichever is higher. The bottom 213 of the wells should be screened. H. GROUNDWATER MONITORING The Town of Wappinger upgraded specific aspects of it's initial Landfill Closure Plan to comply with the Part 360 regulations effective December 31, 1988 in an effort to secure State Assistance under the Environmental Quality Bond Act (EQBA). Part of this upgrade included installation of two (2) monitoring wells downgradient of the landfill in an effort to reduce future environmental monitoring costs. This reduction in the sampling requirements was detailed in a March 22", 1995 correspondence from Alan A. Fuchs, Solid Waste Engineer -- Region 3 to Supervisor Constance O. Smith, which indicated: "The N. Y.&D.E. (7. is willing to reduce the landfill's water quality sampling requiremernts if two monitoring wells are added to the monitoring network which are clearly capable of'detecting the landfill's water quality impact. The proposed water -quality monitoring reduction is to decrease the required number of sampling locations per sampling event from five to three monitoring wells. The proposed program would include two monitoring wells downgradient of the landfill and one upgradient monitoring location. " The Town proposes to perform annual baseline and quarterly routine monitoring of downgradient wells PMW-8 and PMW-9 and the existing upgradient production well as indicated on the "As -Built" Plan. Said sampling schedule would be conducted at this frequency until a minimum of ten (10) rounds of test results are collected. After that time, and depending on the results obtained, the Town of Wappinger may request that the N.Y.S.D.E.C. modify the sampling and analysis requirements pursuant to the Local Government Regulatory Relief/Initiative as follows: Speci is Variance: Post Closure MonitoringI: The frequency of post -closure groundwater, surface water and leachate monitoring required by 6 NYCRR Part 360-2.15(i)(4) may be reduced from annually for baseline parameters and quarterly for routine parameters to annually for routine parameters and once every five years for baseline parameters [See 6 NYCRR Part 360-2.11(c) (6)]. _10- In addition, post -closure monitoring and maintenance shall include regular inspection of the landfill final cover and surrounding area for cracks or stressed vegetation which might indicate the escape of landfill gas. Areas where there are cracks or where vegetation appears stressed shall be tested with a portable explosive gas detector. Any areas of the final cover which may have been damaged should be repaired and steps shall be taken, such as the installation of additional gas vents, to prevent future damage, Areas around the waste mass where gas is found to be escaping shall be tested with a portable explosive gas detector to determine whether they indicate pathways by which explosive gas is migrating offsite. If so, additional measures shall be taken to prevent offsite migration, The percentage of explosive gas emanating from gas vents shall be measured to indicate the effectiveness of the gas vents. All gas monitoring shall be performed when the atmospheric pressure is low (below 29.92 inches of mercury). Atmospheric pressure shall be recorded along with the other monitoring results. If the landfill is on a property that is sufficiently large as to preclude offsite migration of landfill gas, then the perimeter explosive gas monitoring requirements are inapplicable. In order to qualify for omission of the perimeter monitoring requirements, the distance from the waste mass to the property boundary must be a minimum of 1,000 feet or adequate onsite barriers to gas migration must exist. A barrier to gas migration is either: a ravine or excavation with its base extending as deep as the base of the waster mass, or to very low permeability soils or seasonal low groundwater, or a surface water that has flow all year, and which is indicative of groundwater elevation. Said gas monitoring shall be performed by qualified professional firms on an individual contract basis with the Town of Wappinger subsequent to an informal bid process, Results shall be submitted to the N.Y.S.D.E.C. as part of the Annual Inspection Report. Guidance: This means that the frequency and cost of past -closure testing for contamination would be significantly reduced. In order to qualify for this variance, all of the following conditions should be met. 1. Contamination, except for leachate indicators, in down -gradient groundwater monitoring wells does not exceed the groundwater standard or background level, whichever is higher, for any contaminant. 2. The landfill is closed and maintained such that no surface leachate is allowed to discharge from the facility; and, There is no contamination of surface waters once cap construction is complete. 4, The landfill should not be located over a sole source or primary aquifer, Based on the post -closure monitoring results, N.Y.S.D.E.C. may require more frequent monitoring at a later time. Said water quality monitoring shall be performed by qualified professional firms on an individual contract basis with the Town of Wappinger subsequent to an informal bid process, Results shall be submitted to the N.Y.S.D:E.C. as part of the Annual Inspection Report. Baseline and routine test parameters are as follows: - 11- LEACHATE COLLECTION SYSTEM: Leachate control systems have not been designed as part of this landfill closure plan. The soil cap will prevent rainwater from infiltrating into the landfill mass, thus restricting potential leachate development. The grading of the site, as discussed in previous sections, will encourage surface water to flow off the landfill mass and thus, prevent further leachate from forming. During the quarterly visual inspections, leachate outcropping will be looked for. If found, it will be immediately noted and proper engineering control measures (as approved by the N.Y,S.D.E.C,) shall be implemented. Said quarterly inspections shall be performed by Town of Wappinger personnel, or their designated representatives and the results submitted to the N.Y.S.D.E.C, as part of the Annual Inspection Report, -20- RECORDKEEPING AND REPORTING: Quarterly visual inspections of the site will be conducted by Town personnel or their designated representatives for the minimum post closure period following completion of the landfill closure. These reports will be filed at the Town Hall. These inspections will include the soil cap and topsoil, venting system, site drainage, specifically any items such as subsidence of the soil cap, areas of the erosion, dead or dying vegetation, vandalism, and vectors will be reported immediately to Town personnel followed by taking of corrective action. In addition, qualified professional firms will be contracted with to perform quarterly and annual groundwater duality and gas monitoring following N.Y. S. D.E.C. protocols. An annual report will be submitted to N.Y.S.D.E.C, which contains an analysis of the groundwater quality sampling, gas monitoring and annual inspection report by the Town of Wappinger identifying results of the quarterly visual inspections, and any maintenance necessary during the year. Copies of all said information shall be available for inspection at the Town of Wappinger Town Hall. -21- K. RESOURCE REQUIREMENTS: Quarterly visual inspections of the soil cap, vegetative cover, site drainage, venting system, areas of subsidence, erosion, dying vegetation, vandalism and vectors shall be performed by Town of Wappinger personnel or their designated representatives, The Town of Wappinger work force includes staff and equipment sufficient to perform this work. Quarterly water quality and gas monitoring shall be performed by qualified professional firms on an individual contract basis with the Town of Wappinger subsequent to an informal bid process. The names and contact numbers of said professional firms shall be provided to the N.Y,S.D.E.C. as they become available. -22- M. FINANCIAL ASSURANCE CRITERIA; The Town of Wappinger is in the process of securing bids for quarterly water quality and gas monitoring services as detailed herein. Upon final acceptance of a qualified professional firm, the estimated yearly costs to perform the prescribed work will be submitted to the NX.S.D.E.C. All other work will be performed on a force account basis by Town personnel. The Town of Wappinger owns and will continue to own the Castle Point Landfill site, and will be financially responsible for post -closure monitoring and maintenance. -24- En Q I° Wal APPROXIMATE �n11 C pir ) I C "20 1 r 0 EXISTING WELL TOP OF CASING = 109.4 u 0 Lit U w z BENCHMARK z SOUTHWEST CORNER OF MONUMENT - X ASSUMED ELEVATION iv U JOO.O GV -6 0 P TREELINE (TYP.)- 0 /*5 i A GV -5 ads � ♦ r GV -13 OQ 4z A GV -7 Not' Tt) 13E TlZSTlr=0 PMW - 3 TOP OF CASING = 66.55 CONCRETE PAD - 62.80 A 0 J BALLFIELD JU 0� ® PMW - 4 TOP OF CASING = 67.68 ON CCRETE PAD 65.41 N OT" To >� TEST x z f0 I z Q U A07 TO (3r-- 0 T'FSTW PMW - 5 TOP OF CASING - 68.02 CONCRETE PAD - 65.58 CONCRETE „ MONUMENT �~ 0�� }L4NOML CLASM BIaRO,,IBCi _ W TM OF VAN11110111M lu.
