Activities on Site include site inspections, and groundwater monitoring. The Site was remediated in accordance with the Record of Decision (ROD) dated January 2008 (NYSDEC, 2008) which is attached as Appendix A. 1.1.1 General The potentially responsible parties for the Site – Town of Cortlandville, Smith Corona, and Overhead doors – declined to assume responsibility for the remedial action (RA) at the Site, so the NYSDEC conducted the remediation of the approximately 2.5-acre property located in Cortlandville, Cortland County, New York through the State Superfund (SSF) program. A map showing the Site location is provided as Figure 1. The boundaries of the Site are more fully described in the metes and bounds site description that accompanies the Land Title Survey completed in March 2013 by Fisher Associates, Rochester, NY and attached as Appendix B to this SMP. After completing the remedial work at the site described in the March 2011 Remedial Action Contract Documents (MACTEC Engineering and Consulting, P.C. [MACTEC], 2011a), contamination greater than NYS Standards Guidance and Criteria (i.e., landfilled waste) remains at the Site – hereafter referred to as ‘remaining contamination’. This SMP has been prepared to manage remaining contamination at the Site in perpetuity or until extinguishment of the Environmental Easement in accordance with Environmental Conservation Law Article 71, Title 36. The RA, including solid waste consolidation and installation of a landfill soil cover, began at the Site in 2011 and was completed in 2012. Reports associated with the Site can be viewed by contacting the NYSDEC or visiting the document repository at the Cortlandville Town Hall, located at 3577 Terrace Road in the Town of Cortland. This SMP was prepared by MACTEC , on behalf of the NYSDEC for the South Hill Dump Site in 2015, and updated by CHA Consulting, Inc. (CHA), in accordance with the requirements in NYSDEC DER-10 Technical Guidance for Site Investigation and Remediation (NYSDEC, 2010), 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 2 and the guidelines provided by the NYSDEC. This SMP addresses the means for implementing the Institutional Controls (ICs) and Engineering Controls (ECs) that are required by the Environmental Easement for the Site. The Environmental Easement is included in Appendix C. 1.1.2 Purpose After completion of the RA, contamination remains at the Site. ECs were incorporated into the Site remedy to provide proper management of remaining contamination in the future to ensure protection of public health and the environment. The ICs place restrictions on site use and mandate operation and maintenance (O&M) and reporting measures for ECs and ICs. An Environmental Easement was granted in October 2013 by the responsible parties in favor of the NYSDEC and recorded with the Cortland County Clerk to provide an enforceable legal document to ensure compliance with this SMP and all ECs and ICs placed on the Site. This SMP has been approved by the NYSDEC, and compliance with this SMP is required by the future grantor of the Environmental Easement and the grantor’s successors and assigns. This SMP may be revised only with approval of the NYSDEC. This SMP provides a detailed description of procedures required to manage remaining contamination at the Site after completion of the RA, including: (1) Implementation and management of ECs/ICs; (2) media monitoring; (3) performance of periodic inspections, certifications of results, and (3) submittal of Periodic Review Reports (PRRs). Table 1.1 summarizes the SMP requirements. To address these needs, this SMP includes three plans: • An Institutional and Engineering Control Plan for implementation and management of IC/ECs (Section 2.0 of this SMP) • A Monitoring Plan for implementation of Site monitoring (Section 3.0) • An O&M Plan for implementation of remedial containment systems (Section 4.0) It is important to note that: • This SMP details the Site-specific implementation procedures associated with the Site that is required by the Environmental Easement. Failure to properly implement the SMP is a violation of Environmental Conservation Law and the Environmental Easement, which is grounds for revocation of the Certificate of Completion • Failure to comply with this SMP is also a violation of, Title 6 of the New York Codes, Rules, and Regulations (NYCRR) Part 375 and the ROD dated January 2008 for Site #712009 and thereby subject to applicable penalties. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 3 At the time this SMP was prepared, Site documents related to the Remedial Investigation (RI) and the RA for the Site were maintained at the NYSDEC Headquarters in Albany, New York or the Cortlandville Town Hall repository. 1.1.3 Revisions It is anticipated that revisions to the SMP will be completed by the NYSDEC. If the Site owner desires to make revisions to the SMP, the revisions will be proposed in writing to the NYSDEC’s project manager (PM). In accordance with the Environmental Easement for the Site, the NYSDEC will provide a notice of any approved changes to the SMP and append these notices to the SMP that is retained in its files. 1.2 SITE BACKGROUND 1.2.1 Site Location and Description The Site is located in the Town of Cortlandville, New York, two miles south of the Village of McGraw, on the south side of South Hill Road (Figure 1). A mix of forested areas and apple orchards are located east of the Site. The area west and north of the Site consists primarily of active farmland. The topography in this area slopes to the south, toward an unnamed stream located approximately 1/4 mile south of the Site. The unnamed stream discharges to the Tioughnioga River via Hoxie Gorge Creek which is located approximately one mile from the Site. 1.2.2 Site History The Site was operated as a municipal waste disposal facility by the Town of Cortlandville from the early 1960s until 1972, although it is reported that local residents used the Site for trash disposal as early as 1949. During its years of operation, wastes were received from the Village of McGraw and the Towns of Cortlandville and Solon, as well as local industry. Access to the Site was reportedly unrestricted. In 1990, the NYSDEC conducted a Site inspection and collected soil and leachate samples. Analysis revealed the presence of chlorinated solvents and pesticides. Based on this data, the observed condition of the landfill (leachate seeps, numerous drum carcasses, etc.) and reported waste disposal history, the Site was proposed for listing on the NYS Hazardous Waste Site Registry in February 1991 and assigned a Class 2 designation. Class 2 Sites are defined as those which pose a significant 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 4 threat to the public health or environment. In March 1991 five drums of hazardous waste were removed from the Site. Analysis revealed that the drums contained trichloroethene (TCE). In 1991 and 1992, the Cortland County Planning Department (CCPD) collected several surface water samples at the Site from the intermittent stream at the toe of the landfill. Analytical data revealed relatively high concentrations of the solvents TCE and 1,2-dichloroethene (1,2-DCE). In 1994, the NYSDEC collected surface water samples, sediment samples and soil samples from the Site. Analytical results revealed the presence of TCE and 1,2-DCE at concentrations slightly above NYSDEC guidance values. The samples were collected in immediate proximity to the CCPD sample locations. One sediment sample contained a relatively low concentration (9 micrograms per liter [µg/L]) of TCE. Polychlorinated biphenyls (PCBs) (at 79 µg/L) were detected in one sediment sample. Sediment sample results revealed relatively high concentrations of several metals including copper, mercury, nickel, and zinc. Analysis of the soil samples revealed relatively low concentrations of TCE, PCBs, cadmium, copper, and polycyclic aromatic hydrocarbons (PAHs). Based upon the findings of the sampling programs, a RI was deemed necessary. 1.2.3 Geologic Conditions Overburden at the Site consists of a dense compacted mixture of silt and clay with minor amounts of sand and gravel. The overburden is up to 30 feet thick in the area of the Site, and overlies shale and bedrock. The bedrock underlying the Site consists of shale units of the Upper Devonian Genesee Group. The upper 20 feet of bedrock is characterized as grey fossiliferous shale, with a weathered surface of one to three feet. Groundwater flow at the Site in both the overburden and the bedrock is to the south. Groundwater elevation data indicates a general downward vertical gradient between the till and bedrock water bearing units, suggesting that vertical flow, if any, would be from the overburden into the bedrock (NYSDEC, 2003). 1.3 SUMMARY OF REMEDIAL INVESTIGATION FINDINGS The RI field work was conducted by Parsons Engineering Science, Inc., of Liverpool, New York, under contract to the NYSDEC. The RI Report was completed by the NYSDEC (NYSDEC, 2003). 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 5 The RI included the following activities: • A records search to identify the Site history, past operations and contaminants of concern. The records search involved a review and compilation of available State, County, and Town records pertaining to the Site. • Development of a Site base map illustrating Site topographic contours, roadways, property boundaries, and environmental sample locations. • A test pit investigation to visually delineate the extent of subsurface contamination and characterize the shallow overburden geology. • Collection and analysis of subsurface soil samples during the test pit investigation to identify the nature of the contamination present. • Collection and analysis of sediment and surface water samples from visible seeps and from the intermittent stream located at the toe of the landfill. • Installation of groundwater monitoring wells in overburden and bedrock to characterize Site geology and hydrogeology. • Collection and analysis of subsurface soil samples during the installation of monitoring wells. • Collection and analysis of groundwater samples to identify potential Site impacts to groundwater. • A Fish and Wildlife Impact Analysis to identify existing or potential impacts to fish and wildlife. • Review of Applicable Standards, Criteria, and Guidance (SCGs) and comparison to on-Site contaminant levels to assess the threat, if any, posed at the Site. The RI report recommended that a Feasibility Study and subsequent RA be conducted due to the following reported concerns: • Unregulated historic landfill operation • Observation of existing waste protruding from the ground surface • Reported contamination in Site soil, surface water, sediment, and groundwater • Unfavorable geologic conditions, particularly the relatively shallow depth to fractured bedrock; and • Likely existence of additional drums within the landfill; the drums may be acting as a continuing source of contamination, creating potential for long-term offsite migration via surface water or groundwater. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 6 1.4 SUMMARY OF REMEDIAL ACTIONS An interim remedial measure was implemented by the NYSDEC on March 17, 1997. Marcor Environmental pumped 660 gallons of liquid (water reportedly containing a non-aqueous phase liquid) into a tanker truck from a test pit (TP-40 on the eastern edge of the landfill). Samples were collected for analysis to characterize the liquid for offsite disposal. Analysis revealed the presence of 1,2-DCE, TCE, vinyl chloride, acetone, methylphenol and several inorganics including calcium, iron, magnesium, and potassium. The waste was disposed at CWM Chemical Services in Model City, NY. The Site was subsequently remediated in accordance with the ROD dated January 2008, and as documented in the Final Engineering Report (FER) (MACTEC, 2013). RAs conducted during implementation of the ROD included: • Installation of stabilized vehicle entrance. • Installation of perimeter erosion and sedimentation controls • Clearing of trees and brush above the ground surface • Grubbing of areas within the limit of grading, and disposal of grubbings onsite (beneath the new landfill cover) • Excavation of onsite waste outside the new solid waste boundary and consolidation within the new solid waste boundary • Decommissioning of two existing groundwater monitoring wells • Installation of additional erosion and sedimentation controls and measures, including the sedimentation basin, in preparation for landfill grading and soil cover installation • Grading of the landfill within the new solid waste boundary to achieve subgrade and/or the minimum grading performance criteria • Excavation as required for installation of landfill storm water controls (slope benches and downdrains) within the new solid waste boundary • Removal of bulky waste items uncovered during the course of waste consolidation and landfill grading, with off-site disposal of removed bulky wastes • Characterization and offsite disposal of uncovered buried waste drums, drum nests, drum remnants, and adjacent spilled/leaked contents and visually impacted soils • Installation of landfill cover system including associated landfill storm water controls • Installation of landfill gas vents • Installation of perimeter access road with waterbars 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 7 • Installation of perimeter storm water controls including riprap drainage channel, east drainage swale, and culverts • Cleaning of sediment basin and outlet structure of accumulated sediment, and conversion to a storm water detention basin • Installation of two new groundwater monitoring wells • Seeding and mulching of all vegetated areas within the limit of work. Remedial construction activities for the Site were completed in December 2012. 1.4.1 Remaining Contamination Remaining contamination at the Site consists primarily of municipal and industrial wastes beneath the landfill cover. 1.4.2 Engineering and Institutional Controls Because remaining contamination is present at this Site, ECs and ICs have been implemented to protect public health and the environment for the applicable future use. The Controlled Property has the following ECs: • a cover system placed over the landfilled waste • site access controls • surface water drainage conveyance • landfill gas vents A series of ICs are required to implement, maintain, and monitor these ECs. The Environmental Easement requires compliance with these ICs, to ensure that: • All ECs must be operated and maintained as specified in this SMP • All ECs on the Site must be inspected and certified at a frequency and in a manner defined in this SMP • Environmental monitoring must be performed as defined in this SMP • Data and information pertinent to SM for the Controlled Property must be reported at the frequency and in a manner defined in this SMP • On-site environmental monitoring devices, including but not limited to groundwater monitoring wells, must be protected and replaced as necessary to ensure continued functioning in the manner specified in this SMP. In addition, the Environmental Easement places the following restrictions on the property: 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 8 • Required compliance with the approved SMP. Restrict the use of groundwater as a source of potable water, without necessary water quality treatment as determined by the New York State Department of Health (NYSDOH) and/or the NYSDEC • The owner of the Property shall provide information to the NYSDEC to assist it in carrying out its obligation to provide a periodic certification, prepared and submitted by a professional engineer or environmental professional acceptable to the NYSDEC or Relevant Agency, which will certify that the IC/ECs put in place are unchanged from the previous certification, comply with the SMP, and have not been impaired • The owner of the Property shall continue in full force and effect any IC/ECs required for the Remedy and shall not, through any act or omission, interfere with the NYSDEC’s maintenance and monitoring of such controls, unless the owner first obtains permission to discontinue such controls from the NYSDEC or Relevant Agency, in compliance with the approved SMP subject to modifications as approved by the NYSDEC or Relevant Agency • Limit the use and development of the property to the current use as a closed and capped/covered landfill only. These EC/ICs are designed to: • Prevent ingestion/direct contact with remaining contamination • Prevent inhalation of or exposure to contaminants volatilizing from remaining contamination • Prevent ingestion of groundwater with contaminant levels that exceed drinking water standards • Prevent contact with or inhalation of volatiles from contaminated groundwater. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 9 2.0 ENGINEERING AND INSTITUTIONAL CONTROL PLAN 2.1 INTRODUCTION Remedial activities completed at the Site were conducted in accordance with the January 2008 ROD and the NYSDEC-approved remedial design for South Hill Dump, March 2011 as outlined within the Contract Documents. The remedial goals for this site, as presented in the ROD, are to eliminate or reduce to the extent practicable: • exposures of persons and wildlife at or around the site to waste, sediment and surface soil • the release of contaminants from the waste into groundwater that may create exceedances of groundwater quality standards • prevent releases of contaminants from the waste that would result in surface water levels in excess of ambient water quality criteria. Further, the remediation goals for the site include attaining to the extent practicable: • ambient groundwater quality standards • soil cleanup standards. Because remaining contamination is present at the Site, EC/ICs are required to protect human health and the environment. This EC/IC Plan describes the procedures for the implementation and management of EC/ICs at the Site. The EC/IC Plan is one component of the SMP and is subject to revision by the NYSDEC. 2.1.1 Purpose The purpose of this EC/IC Plan is to provide: • A description of all EC/ICs on the Site • The basic operation and intended role of each implemented EC/IC • A description of the key components of the IC s created stated in the Environmental Easement • A description of the features that should be evaluated during each periodic inspection and compliance certification period • A description of plans and procedures to be followed for implementation of EC/ICs, such as the implementation of an Excavation Plan (EP) for the safe handling of remaining contamination that may be disturbed during maintenance or development work on the Site 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 10 • Any other provisions necessary to identify or establish methods for implementing the EC/ICs required by the Site remedy, as determined by the NYSDEC • A description of the reporting requirements for these controls. 2.2 ENGINEERING CONTROLS This section describes the ECs at the Site. 2.2.1 Engineering Control Systems There are currently four EC systems at the Site: • Landfill Cover System • Site Access Controls • Surface Water Drainage Conveyance • Landfill Gas Vents 2.2.1.1 Landfill Cover System Exposure to remaining contamination at the Site is prevented by a landfill cover system placed over the landfilled waste. The cover (see Figure 2 for typical cross section) is comprised of: • cover soil layer – 18-inch thickness, • vegetative (top soil and seed) layer – six-inch thickness. The Excavation Plan (Section 2.4) outlines the procedures required to be implemented in the event the landfill cover is breached, penetrated, or temporarily removed, and any underlying remaining contamination is disturbed. Procedures for the inspection and maintenance of the landfill cover are provided in the O&M Plan discussed in Section 4 of this SMP. 2.2.1.2 Site Access Controls The Site includes site access via a stone road that provides access to and around the perimeter of the landfill area. The Site is in a relatively remote area, with only occasional passersby typically observed. Access to the site is controlled by a newly-constructed chain link fence along the South Hill Road side of the property (where vehicles enter on the access road) which serves to discourage trespassers. The fence contains a locked gate across the access road entrance. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 11 2.2.1.3 Surface Water Drainage Conveyance The site drainage system includes a riprap-lined drainage swale at the eastern side of the property, and a storm water detention basin at the property’s south end into which drains runoff from the stone-lined drainageways on the landfill cover. The detention basin outlet drains to an unnamed stream which eventually discharges to the Tioughnioga River via Hoxie Gorge Creek. Procedures for maintaining the drainage systems are documented in the O&M Plan discussed in Section 4 of this SMP. Procedures for monitoring the system are included in the Monitoring Plan (Section 3 of this SMP). 2.2.1.4 Landfill Gas Vents Seven passive landfill gas vents penetrate the landfill cover. The purpose of the vents is to collect potential landfill gas for direct venting to the atmosphere, thereby preventing subsurface gas migration. 2.2.2 Criteria for Completion of Remediation / Termination of Remedial Systems Generally, the remedial processes will be considered to be completed when effectiveness monitoring indicates that the remedy has achieved the RA Objectives identified by the ROD. The specific determination of when the following remedial processes are complete will be made in compliance with Section 6.5 of the NYSDEC DER-10, May 2010. The landfill cover is a permanent control and the quality and integrity of this system will be inspected at defined, regular intervals (see Subsection 4.1 of this SMP for the inspection schedule), until such time that the NYSDEC agrees in writing that inspection of this system is no longer required. 2.3 INSTITUTIONAL CONTROLS ICs are required by the ROD to: (1) implement, maintain and monitor EC systems; (2) prevent future exposure to remaining contamination by controlling disturbances of the subsurface contamination; and, (3) limit the use and development of the Site to the current use. Adherence to these ICs on the Site is required by the Environmental Easement and will be implemented under this SMP. These ICs are: 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 12 • Compliance with the Environmental Easement by the Grantor and the Grantor’s successors and assigns with all elements of this SMP • All ECs must be operated and maintained as specified in this SMP • All ECs on the Controlled Property must be inspected and certified at a frequency and in a manner defined in the SMP • Environmental monitoring must be performed as defined in this SMP • Data and information pertinent to SM for the Controlled Property must be reported at the frequency and in a manner defined in this SMP • On-site environmental monitoring devices, including but not limited to groundwater monitoring wells, must be protected and replaced as necessary to ensure the devices function in the manner specified in this SMP. ICs may not be discontinued without an amendment to or extinguishment of the Environmental Easement. The Site has a series of ICs in the form of site restrictions. Adherence to these ICs is required by the Environmental Easement. Site restrictions that apply to the Controlled Property are: • Groundwater – use restriction covers the entire Environmental Easement area • SMP – covers entire Environmental Easement area • The use and development of the site is limited to its current use as a closed and capped/covered landfill • Compliance with the Environmental Easement and the SMP by the Grantor and the Grantor’s successors and assigns • All ECs must be operated and maintained as specified in the SMP • All ECs on the Controlled Property must be inspected at a frequency and in a manner defined in the SMP • Groundwater, soil vapor, and other environmental or public health monitoring must be performed as defined in the SMP • Data and information pertinent to SM of the Controlled Property must be reported at the frequency and in a manner defined in the SMP • The property may not be used for a higher level of use, such as unrestricted use without additional remediation and amendment of the Environmental Easement, as approved by the NYSDEC • All future activities on the property that will disturb remaining contaminated material must be conducted in accordance with the SMP • The use of the groundwater underlying the property is prohibited without treatment rendering it safe for intended use 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 13 • Vegetable gardens and farming on the property are prohibited • The site owner or remedial party will submit to NYSDEC a written statement that certifies, under penalty of perjury, that: (1) controls employed at the Controlled Property are unchanged from the previous certification or that any changes to the controls were approved by the NYSDEC; and. (2) nothing has occurred that impairs the ability of the controls to protect public health and environment or that constitute a violation or failure to comply with the SMP. The NYSDEC retains the right to access such Controlled Property at any time in order to evaluate the continued maintenance of any and all controls. This certification shall be submitted annually, or an alternate period of time that the NYSDEC may allow and will be made by an expert that the NYSDEC finds acceptable. 2.4 EXCAVATION PLAN The site remedy allows for current use as a closed and capped/cov ered landfill only. Any future intrusive work that will penetrate, encounter, or disturb the remaining contamination, and any modifications or repairs to the existing cover system will be performed in compliance with this excavation plan (EP). Intrusive construction work must also be conducted in accordance with the procedures defined in a Health and Safety Plan (HASP) and Community Air Monitoring Plan (CAMP) prepared by the contractor. The HASP must be in compliance with DER-10, and 29 CFR 1910, 29 CFR 1926, and all other applicable Federal, State and local regulations. Based on future changes to State and federal health and safety requirements, and specific methods employed by future contractors, the HASP and CAMP will be updated an re-submitted with the notification provided below. Any intrusive construction work will be performed in compliance with the EP, HASP, and CAMP, and will be included in the periodic inspection and certification reports submitted under the SM Reporting Plan (See Section 2.6). The parties preparing the remedial documents submitted to the NYSDEC, and parties performing this work, are completely responsible for the safe performance of all invasive work and the structural integrity of excavations. The Site owner will ensure that site development activities will not interfere with, or otherwise impair or compromise, remedial activities ongoing in this SMP. Mechanical processing of historical fill and contaminated soil on-site is prohibited. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 14 2.4.1 Notification At least 10 days prior to the start of any activity that is reasonably anticipated to encounter remaining contamination, the Site owner or their representative will notify the NYSDEC. Currently, this notification will be made to: Brianna Scharf, Project Manager NYSDEC Remedial Bureau E, Section C Division of Environmental Remediation 518-402-5987 Brianna.scharf@dec.ny.gov This notification will include: • A detailed description of the work to be performed, including the location and areal extent, plans for site re-grading, intrusive elements or utilities to be installed below the landfill cover, or any work that may impact an EC • A summary of environmental conditions anticipated in the work areas, including the nature and concentration levels of contaminants of concern (COCs), potential presence of grossly contaminated media, and plans for any pre-construction sampling • A schedule for the work, detailing the start and completion of all intrusive work • A statement that the work will be performed in compliance with this EP and 29 CFR 1910.120 • A copy of the contractor’s HASP, in electronic format • Identification of disposal facilities for potential waste streams • Identification of sources of any anticipated backfill, along with all required chemical testing results. 2.4.2 Soil Screening Methods Visual, olfactory, and instrument-based soil screening will be performed by a qualified environmental professional (QEP) during all remedial and development excavations into known or potentially contaminated material (remaining contamination). Soil screening will be performed regardless of when the intrusive work is done and will include all excavation and invasive work performed during development, such as excavations for foundations and utility work. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 15 Soils will be segregated based on previous environmental data and screening results into material that requires off-site disposal, material that requires testing, material that can be returned to the subsurface, and material that can be used as cover soil. 2.4.3 Stockpile Methods Soil stockpiles will be continuously encircled with a berm and/or silt fence. Hay bales will be used as needed near catch basins, surface waters, and other discharge points. Stockpiles will be kept covered at all times with appropriately anchored tarps. Stockpiles will be routinely inspected and damaged tarp covers will be promptly replaced. Stockpiles will be inspected at a minimum once each week and after every storm event. Results of inspections will be recorded in a logbook and maintained at the Site and available for inspection by the NYSDEC. 2.4.4 Materials Excavation and Disposal A QEP or person under their supervision will oversee all invasive work and the excavation and disposal of all excavated material. The presence of utilities and easements on the Site will be investigated by the QEP. Prior to any excavation work the QEP will determine whether a risk or impediment to the planned work under this SMP is posed by utilities or easements on the Site. Prior to excavation, a call is to be placed to the Call Before You Dig Number 811 for consultation regarding underground utility lines. Loaded vehicles leaving the Site will be appropriately lined, tarped, securely covered, manifested, and placarded in accordance with appropriate Federal, State, local, and NYS Department of Transportation requirements (and all other applicable transportation requirements). Locations where vehicles enter or exit the Site shall be inspected daily for evidence of off-site soil tracking. The QEP will be responsible for ensuring that all egress points for truck and equipment transport from the Site are clean of dirt and other materials derived from the Site during intrusive excavation activities. Cleaning of the adjacent streets will be performed as needed to maintain a clean condition with respect to site-derived materials. 2.4.5 Materials Transport Off-Site All transport of materials will be performed by licensed haulers in accordance with appropriate local, State, and Federal regulations, including 6 NYCRR Part 364. Haulers will be appropriately licensed and trucks properly placarded. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 16 Material transported by trucks exiting the Site will be secured with tight-fitting covers. Loose-fitting canvas-type truck covers will be prohibited. If loads contain wet material capable of producing free liquid, truck liners will be used. Truck transport routes will be identified that will: (a) limit transport through residential areas and past sensitive sites; (b) use city-mapped truck routes; (c) minimize off-site queuing of trucks entering the facility; (d) limit total distance to major highways; and (e) promote safety in access to highways. Trucks will be prohibited from stopping and idling in the neighborhood outside the project site. Egress points for truck and equipment transport from the Site will be kept clean of dirt and other materials during site remediation and development. Due to limited available space at the Site, some off-site queuing of trucks may be necessary. The number and duration of trucks lined up outside the site entrance will be minimized through efficient scheduling and staging at a remote location. Offsite transport activities will be coordinated with activities by owner and its affiliates or tenants at the Site so as to minimize, to the extent practical, disruption of their activities. 2.4.6 Materials Disposal Off-Site All soil/fill/solid waste excavated and removed from the Site will be treated as contaminated and regulated material and will be transported and disposed in accordance with all local, State (including 6 NYCRR Part 360) and Federal regulations. Waste characterization sampling will be in accordance with Part 1.06 of the Waste Removal, Handling, and Storage specification included in Appendix D. If disposal of soil/fill from this site is proposed for unregulated off-site disposal (i.e. clean soil removed for development purposes), a formal request with an associated plan will be made to the NYSDEC. Unregulated off-Site management of materials from this site will not occur without formal NYSDEC approval. Off-site disposal locations for excavated soils will be identified in the pre-excavation notification. This will include quantities and a breakdown by class of disposal facility if appropriate, i.e. hazardous waste disposal facility, etc. Actual disposal quantities and associated documentation will be reported to the NYSDEC in the PRR. This documentation will include: waste profiles, test results, facility acceptance letters, manifests, bills of lading and facility receipts. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 17 Non-hazardous historic fill and contaminated soils taken off-site will be handled, at minimum, as a Municipal Solid Waste pursuant to 6 NYCRR Part 360-1.2. Material that does not meet the lower of the SCGs for residential use or groundwater protection will not be taken to a NYS recycling facility (6 NYCRR Part 360-16 Registration Facility) without a beneficial use determination issued by the NYSDEC. The United States Environmental Protection Agency (USEPA) generator identification number for this Site is NYP003602158. 2.4.7 Materials Reuse On-Site A QEP will ensure that procedures defined for materials reuse in this SMP are followed and that unacceptable material does not remain on-site. Contaminated on-site material, including historic fill and contaminated soil, that is acceptable for re-use on-site will be placed below the demarcation layer or impervious surface, and will not be reused within a cover soil layer or as backfill for subsurface utility lines. Any demolition material proposed for reuse on-site will be sampled for asbestos and the results will be reported to the NYSDEC for acceptance. Concrete crushing or processing on-site will not be performed without prior NYSDEC approval. Organic matter (wood, roots, stumps, etc.) or other solid waste derived from clearing and grubbing of the Site will not be reused on-site. 2.4.8 Fluids Management All liquids to be removed from the Site, including excavation dewatering and groundwater monitoring well purge and development waters, will be handled, transported, and disposed in accordance with applicable local, State, and Federal regulations. Dewatering, purge, and development fluids will not be recharged back to the land surface or subsurface of the Site, but will be managed off-site. Waste characterization sampling will be in accordance with Part 1.06 of the Waste Removal, Handling, and Storage specification included in Appendix D. 2.4.9 Cover System Restoration After the completion of soil removal and any other invasive remedial activities the landfill cover will be restored in a manner that complies with the ROD and the approved remedial design as outline within the Contract Documents. If the type of landfill cover changes from that which exists prior to the excavation (i.e., cover soil is replaced by geofabric), this will constitute a modification of the cover element of the remedy and the upper surface of the Remaining Contamination. A figure 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 18 showing the modified surface will be included in the subsequent PRR and in any updates to the SMP. 2.4.10 Backfill from Off-Site Sources All materials proposed for import onto the Site will be approved by the QEP and will be in compliance with provisions in this SMP, applicable regulations (6 NYCRR 375-6.7(d)) and guidance (DER-10) prior to receipt at the Site. Material from industrial sites, spill sites, or other environmental remediation sites or potentially contaminated sites will not be imported to the Site. All imported soils will meet the backfill and cover soil quality standards established in 6 NYCRR 375-6.7(d). Soils that meet ‘exempt’ fill requirements under 6 NYCRR Part 360, but do not meet backfill or cover soil objectives for this site, will not be imported onto the Site without prior approval by the NYSDEC. Solid waste will not be imported onto the Site. Trucks entering the Site with imported soils will be securely covered with tight fitting covers. Imported soils will be stockpiled separately from excavated materials and covered to prevent dust releases. 2.4.11 Stormwater Pollution Prevention Barriers and hay bale checks will be installed and inspected once a week after every storm event. Results of inspections will be recorded in a logbook and maintained at the Site and available for inspection by the NYSDEC. All necessary repairs shall be made immediately. Accumulated sediments will be removed as required to keep the barrier and hay bale check functional. All undercutting or erosion of the silt fence toe anchor shall be repaired immediately with appropriate backfill materials. Manufacturer’s recommendations will be followed for replacing silt fencing damaged due to weathering. Erosion and sediment control measures identified in the SMP shall be observed to ensure that they are operating correctly. Where discharge locations or points are accessible, they shall be inspected to ascertain whether erosion control measures are effective in preventing significant impacts to receiving waters. Silt fencing or hay bales will be installed around the entire perimeter of the remedial construction area. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 19 2.4.12 Contingency Plan If underground tanks or other previously unidentified contaminant sources are found during post- remedial subsurface excavations or development related construction, excavation activities will be suspended until sufficient equipment is mobilized to address the condition. Sampling will be performed on product, sediment, and surrounding soils, etc. as necessary to determine the nature of the material and proper disposal method. Chemical analysis will be performed for a full list of analytes (target analyte list metals; target compound list [TCL] volatile organic compounds (VOCs), semi-volatiles, TCL pesticides and PCBs), unless the Site history and previous sampling results provide a sufficient justification to limit the list of analytes. In this case, a reduced list of analytes will be proposed to the NYSDEC for approval prior to sampling. Identification of unknown or unexpected contaminated media identifies by screening during invasive site work will be promptly communicated by phone to the NYSDEC’s PM. Reportable quantities of petroleum product will also be reported to the NYSDEC spills hotline. These findings will also be included in daily and periodic electronic media reports. 2.4.13 Community Air Monitoring Plan The contractor will prepare a CAMP, in accordance with Appendix 1A of DER-10 (see Appendix E), showing the location of air sampling stations based on generally prevailing wind conditions. These locations will be adjusted on a daily or more frequent basis based on actual wind directions to provide an upwind and at least two downwind monitoring stations. Exceedances of action levels listed in the CAMP will be reported to the NYSDEC and NYSDOH PMs. 2.4.14 Odor Control Plan If nuisance odors are identified at the Site boundary, or if odor complaints are received, work will be halted and the source of odors will be identified and corrected. Work will not resume until all nuisance odors have been abated. The NYSDEC and NYSDOH will be notified of all odor events and of any other complaints about the project. Implementation of all odor controls, including the halt of work, is the responsibility of the property owner’s Remediation Engineer, and any measures that are implemented will be discussed in the PRR. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 20 All necessary means will be employed to prevent on- and off-site nuisances. At a minimum, these measures will include: (a) limiting the area of open excavations and size of soil stockpiles; (b) shrouding open excavations with tarps and other covers; and (c) using foams to cover exposed odorous soils. If odors develop and cannot be otherwise controlled, additional means to eliminate odor nuisances will include: (d) direct load-out of soils to trucks for off-site disposal; (e) use of chemical odorants in spray or misting systems; and, (f) use of staff to monitor odors in surrounding neighborhoods. If nuisance odors develop during intrusive work that cannot be corrected, or where the control of nuisance odors cannot otherwise be achieved due to on-site conditions or close proximity to sensitive receptors, odor control will be achieved by sheltering the excavation and handling areas in a temporary containment structure equipped with appropriate air venting/filtering systems. 2.4.15 Dust Control Plan A dust suppression plan that addresses dust management during invasive on-site work will include, at a minimum, the items listed below: • Dust suppression will be achieved through the use of dedicated on-site water supply for spraying water directly onto on and off-road areas including excavations and stockpiles. Fugitive dust and particulate monitoring shall be conducted in accordance with Appendix 1B of DER-10 (see Appendix E). 2.5 INSPECTIONS AND NOTIFICATIONS 2.5.1 Periodic Inspections Periodic inspections of remedial components installed at the Site will be conducted at the frequency specified in the SMP Monitoring Plan schedule. Per the direction of the NYSDEC letter dated March 29, 2021, a comprehensive site-wide inspection will be conducted annually, regardless of the frequency of the PRR.

The PRR will be submitted in electronic format to the NYSDEC project manager and the NYSDOH Bureau of Environmental Exposure Investigation. The owner of the Property shall provide information to the NYSDEC to assist it in carrying out its obligation of providing a periodic certification, which will certify that the IC/ECs put in place are 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 24 unchanged from the previous certification, are in compliance with the SMP, and have not been impaired. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 25 3.0 MONITORING PLAN The Monitoring Plan has been designed to: monitor the effect of the landfill on groundwater and surface water in the vicinity of the landfill; to determine if site contaminants are migrating off-Site; and to monitor long term trends in concentrations of contaminants to evaluate the effectiveness of the landfill cap and drainage design. The following sections discuss specific data collection activities that will be conducted to evaluate and monitor the condition of groundwater, surface water, and site drainage sediments, as well as more general field activities that will support the data collection. Figure 3 shows the monitoring locations, and Table 3.1 summarizes the sampling and analysis plan. Table 3.2 presents a summary of the monitoring well network. Boring logs and well completion logs for monitoring wells are included in Appendix F. 3.1 EFFECTIVENESS MONITORING The effectiveness of the landfill cap and drainage design will be evaluated as follows: • Groundwater Elevation Monitoring: The collection of water levels from nine monitoring wells. • Monitoring Well Inventory and Repair: A well inventory will be conducted during each sampling event to document the condition and integrity of the monitoring wells. Observations will be recorded on a monitoring well checklist and/or the field data record (FDR) and the field logbook. Repairs will be made on an as-needed basis. • Groundwater Sampling and Analysis: The collection of “no purge” groundwater samples from nine monitoring wells. Samples will be collected with Hydrasleeve samplers as described in the Site-specific Quality Assurance Project Plan (QAPjP) (Appendix G). • Surface Water/Sediment Sampling and Analysis: The collection of surface water and sediment samples from the outfall of the storm water detention pond located at the southern end of the landfill. The monitoring fieldwork will be conducted in accordance with the Site-specific QAPjP appended to this report (see Appendix G). The monitoring fieldwork activities are described in more detail in the following sections. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 26 3.1.1 Groundwater Elevation Survey A synoptic round of water level measurements will be collected from the nine groundwater monitoring wells at the Site. The monitoring wells are listed on Table 3.2 and locations are shown on Figure 3. Water level measurements will be collected using procedures as described in the QAPP (Appendix G). Water level measurements will be measured to the surveyed top of riser and referenced to the mean sea level. Water levels will be measured to the nearest 0.01 feet, and recorded in the field book and/or the Field Data Record (FDR). The FDR is included in Appendix H. 3.1.2 Groundwater Monitoring Well Inventory and Repair During the water level survey and groundwater sampling activities a monitoring well checklist (Appendix I) will be completed to document the condition and physical details of the monitoring wells. Recommendations to repair damages or deficiencies that are noted during the well inventory will be included in the quarterly landfill inspection reports. Monitoring wells that are no longer functioning will be decommissioned or replaced on an as-needed basis. 3.1.3 Groundwater Sampling As discussed above, groundwater sampling events will be conducted at two year intervals. Groundwater samples will be collected from eleven locations at the Site for the parameters listed in Table 3.1. Monitoring well locations will be sampled following the MACTEC NYSDEC Program QAPP (MACTEC, 2011b). The QAPP describes the hydrasleeve “no purge” sample technique and is located in Appendix G. A Hydrasleeve sampler will be installed in each well as described in the QAPP which will cause a minimal disturbance to sediment at the bottom of the well. The sampler will be left in the monitoring well for a minimum of two weeks before retrieval so that any particulate disturbed during installation can settle out of the water column. Water levels and turbidity readings will be recorded. Samples will be collected for metals and VOCs by USEPA methods 6010B and 8260B, respectively, with standard 30-day turnaround time for laboratory reporting. 3.1.4 Surface Water/Sediment Sampling Concurrent with groundwater sampling, one surface water and one sediment sample will be collected from the storm water detention basin outfall located at the southern end of the Site. The approximate sampling location is shown in Figure 3. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 27 The samples will be collected and documented in accordance with procedures detailed in the QAPP (Appendix G) using a surface water/sediment FDR (Appendix H). The samples will be submitted for offsite laboratory analysis for metals (USEPA method 6010B), VOCs (8260B), and PCBs (8082), with standard 30-day turnaround time for laboratory reporting. 3.1.5 Laboratory Analysis Off-Site laboratory analyses will be performed by, a NYSDOH approved laboratory. Off-Site laboratory analysis will comply with the NYSDEC Analytical Services Protocols (NYSDEC, 2005) for metals, VOCs, and PCBs by the USEPA methods cited previously. 3.2 GENERAL FIELD ACTIVITIES General field activities supporting data collection include health and safety, decontamination, and investigation derived waste disposal. Prior to implementing a monitoring field event, sampling staff will familiarize themselves with Site history, health and safety requirements including preparation of and adherence to Site-specific HASP, equipment calibration procedures, and all other investigation methods and procedures. 3.2.1 Decontamination and Investigation Derived Wastes Sampling methods and equipment for this field program have been chosen to minimize decontamination requirement mitigation potential for cross-contamination. Disposable sampling equipment will be used as much as practical to minimize decontamination time water disposal. Non- disposable sampling equipment will be decontaminated before and after the collection of each sample. Decontamination methods and materials are described in detail in the QAPP (Appendix G). Non-disposable sampling equipment will be decontaminated by washing the sample collection equipment with potable water and non-phosphate detergent (such as Alconox®), rinsing with potable water, rinsing with deionized water, and then allowing the equipment to air dry. Decontamination fluids will be released on-Site to the ground surface in the area of decontamination, so as to allow the liquids to infiltrate into the soil and not run off-Site. In the event that decontamination fluids exhibit visual or olfactory evidence of site related contamination, fluids will be temporarily containerized for offsite disposal. Used protective clothing will be double-bagged in polyethylene trash bags and sealed with twist ties. The bags will be disposed of as municipal solid waste. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 28 Purge water from groundwater sampling will be released on-Site to the ground surface in the area of well, so as to allow the liquids to infiltrate into the soil and not run off-Site. In the event that purge water exhibits visual or olfactory evidence of site-related contamination, fluids will be containerized for sampling and offsite disposal. 3.3 WELL REPAIRS, REPLACEMENT AND DECOMMISSIONING Repairs and/or replacement of groundwater monitoring wells will be performed based on assessments of structural integrity and overall performance. The NYSDEC will be notified prior to any repair, replacement, or decommissioning of monitoring wells, and the notification will be documented in the subsequent monthly report. Well decommissioning without replacement will be done only with prior approval by the NYSDEC. Well abandonment will be performed in accordance with the NYSDEC’s CP-43: “Groundwater Monitoring Well Decommissioning Policy” dated November 3, 2009. Wells that are decommissioned because they have been rendered unusable will be reinstalled in the nearest available location, unless otherwise approved by the NYSDEC. The monitoring well inspection schedule is included in Table 1.1 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 29 4.0 OPERATION AND MAINTENANCE PLAN 4.1 INTRODUCTION The Site does not rely on any mechanical systems, such as sub-slab depressurization systems or air sparge/soil vapor extraction systems to protect public health and the environment. Therefore, the O&M of such components is not applicable and has not been incorporated into this SMP. The O&M Plan for the Site includes: • Inspection and maintenance of the landfill cover system. Landfill inspections will be completed semi-annually in the spring and fall to evaluate and document the conditions at the Site including: o vegetative cover condition o moving required o presence of debris o ponded water o exposed geofabric o erosion o woody growth o leachate seepage o animal burrows • Inspection and maintenance of the surface water drainage conveyance system o drainage channel conditions o erosion/sedimentation o rip-rap condition o condition of culverts • Inspection and maintenance of landfill gas vents • Inspection and maintenance of the chain link fence located along the South Hill Road side of the property (where vehicles enter on the access road) • Inspection and maintenance of groundwater monitoring wells The inspection activities will be documented using an Inspection Form (Appendix I), taking photographs, and noting field observations in a log book. 2021 Site Management Plan South Hill Dump CHA Project No. 34236 Page 30 4.2 CONTINGENCY PLAN In the event of any environmentally related situation or unplanned occurrence requiring assistance the appropriate party from the contact list below shall be notified.

The PRAP outlined the remedial measure proposed for the contaminated groundwater, surface water and sediment at the South Hill Dump site. The release of the PRAP was announced by sending a notice to the public contact list, informing the public of the opportunity to comment on the proposed remedy. A public meeting was held on October 4, 2007, which included a presentation of the Remedial Investigation (RI) and the Feasibility Study (FS) as well as a discussion of the proposed remedy. The meeting provided an opportunity for citizens to discuss their concerns, ask questions and comment on the proposed remedy. These comments have become part of the Administrative Record for this site. The public comment period for the PRAP ended on October 17, 2007. This responsiveness summary responds to all questions and comments raised during the public comment period. The following are the comments received, with the Department's responses: Comment 1: What will be done with the drums in the fenced in area? Response 1: Those drnms will be disposed off site. Comment 2: After the remedy is in place, will the landfill cover be mowed? Response 2: Yes. The cover area will be mowed annually to prevent woody growth. Comment 3: Will there be a fence around the landfill? Response 3: Currently the NYSDEC does not envision a fence around the landfill. During post closure site management, the need for a fence will be routinely re-assessed. Comment 4: Will there be restrictions on how close to the landfill someone can build? Response 4: An environmental easement will be placed on the property. This will preclude anyone from building on the site. Comment 5: Will there be any sampling of the creek at the bottom of the ravine? Response 5: There are currently no plans to re-sample the creek. Sampling during the investigation showed that contamination was not migrating any significant distance from the landfill, and the extent of detected South Hill Dump 712009 RESPONSIVENESS SUMMARY PAGE A-I contamination did not extend beyond the site property boundary. The creek at the bottom of the ravine is approximately 1200 feet from the property. A post-closure monitoring plan will be implemented to ensure that any unanticipated migration of contamination away from the property would be detected. Post-closure environmental monitoring on site will include sampling of sediment and surface water from the drainage swale uphill from the creek as well as groundwater. Comment 6: How long will it be before the remedy is in place? Response 6: After signing the Record of Decision, the Department will attempt to find a responsible party willing to implement the remedy. The timing of the actual design work will depend upon the success of this effort. It is believed that the remedial design can be completed in 2008, and remedial construction can begin in late 2008 or 2009. As noted in Section 7.1 above, it is estimated that remedial construction can be completed in one construction season. Comment 7: When will the remedial construction project go out to bid? Response 7: As discussed above, several tasks need to be completed before the construction project is ready for open bidding. Cun-ently it is estimated that bidding will take place in late 2008 or early 2009. When the project goes out to bid, the Department will place a public notice in the local paper. Comment 8: Wouldn't it be better if the contamination wasn't disturbed? Did the Department consider simply placing the soil cover upon the waste pile as cun-ently configured? Could the regrading release contamination? Response 8: Placing fill on top of the existing waste, without regrading of the material, would result in very steep slopes and create an unacceptable potential for erosion. A community health and safety plan, including a community air monitoring plan, will be in place during any regrading activities at the site. These plans include the utilization of engineering controls to limit fugitive emissions during construction, and dust suppression techniques will be utilized if necessary. Comment 9: The waste pile cun-ently occupies 2.5 acres of the 6-acre parcel. Will you be covering the remaining 3.5 acres? Response 9: Only the areas containing waste will be covered. Institutional controls will be placed on the entire 6-acre parcel, which will provide additional protection against encroachment of future development. Comment 10: Will you be using a hon-ow pit to obtain the soil cover? Response 10: The source of the cover soils isn't known at this time. That decision will be made during the remedial design and remedial construction process. Comment 11: How much will the remediation cost the town? Response 11: Once the remedy has been selected, the NYSDEC's attorneys will contact all the responsible parties (PRP), which will include the Town of Cortlandville, and request that they participate in the funding of the remedy. If an agreement cannot be reached with the PRPs, the NYSDEC will evaluate the site for further action under the State Superfund. The PRPs may be subject to legal actions by the state for recovery of all response costs the state has incun-ed. South Hill Dump 712009 RESPONSIVENESS SUMMARY PAGEA-2 Comment 12: What kind of soils will be used to cover the waste? Response 12: That will be determined during the design studies. A letter from Assemblywoman Barbara Lifton dated October 17, 2007 offered the following comments: Comment 13: Alternative 7 is inadequate because it will not resolve the site's groundwater or soil gas vapor intrusion threat. Response 13: The remedial investigation of the South Hill Dump has shown that migration of contamination from this site has not had a significant impact on the surrounding environment. While contamination of the groundwater was discovered in the vicinity of the waste, which is not unexpected, groundwater in MW-4, the most downgradient monitoring well located at the site boundary, met drinking water standards. Regrading and covering the landfill will further reduce the potential for contaminant migration via the groundwater. The limited extent of contaminant migration in the groundwater, combined with the area's geology and the relative isolation of the site, give confidence that exposure to contaminants through soil vapor intrusion will not be an issue at this site. The Department will develop and implement a post-closure monitoring plan to ensure that the remedy remains protective and that the Department becomes aware in a timely fashion of any change in site conditions that may warrant additional actions. Comment 14: DEC should pursue a plan that includes full remediation of the site, thus eliminating the necessity to put restrictions on groundwater and site use. Response 14: Unfortunately, it is often not feasible to completely excavate historic municipal landfills such as the South Hill Dump and dispose of the waste in modem, permitted facilities. These actions may create significant short-term impacts involving waste management, transportation, and odor control. Alternative 7, while requiring site use restrictions, is protective of human health and the environment. A letter from Jamie Dangler on behalf of the Citizens for Aquifer Protection and Employment dated October 17, 2007, in addition to reiteration of Comment 13 and Comment 14, offered the following comments: Comment 15: It is questionable whether Alternative 7 is more cost-effective in the long-term then Alternative 5 or Alternative 6, and Alternative 7 is less effective in terms ofremediation and protection of human health and wildlife. Response 15: Cost-effectiveness, short-term effectiveness, and long-te1m effectiveness and permanence are three of eight criteria which the Department uses to compare various remedial alternatives. At a minimum, any selected remedial action must be protective of human health and the environment. The Department has determined that Alternative 7 provides the best balance among the eight criteria used to compare the various remedial alternatives and is protective of human health and the environment. Comment 16: Institutional controls will place an indefinite burden on the site owner and will not limit exposure pathways for wildlife. Response 16: Implementation and monitoring of institutional controls are required for any remedy that leaves waste on site to ensure that the remedy remains protective. As noted in Response 14, it is often not feasible to completely excavate and remove all waste from each site. Under Alternative 7, institutional controls will include a prohibition on disturbance of the covered waste, thereby limiting the exposure pathways for wildlife. South Hill Dump 712009 RESPONSIVENESS SUMMARY PAGE A-3 In addition, post-closure monitoring will include sampling at the toe of the covered waste mass to ensure that there are no unacceptable wildlife exposures. It is important to realize that although there are potential exposure pathways at the site, the remedial investigation did not find actual exposure pathways creating a significant threat to fish and wildlife resources, even in the landfill' s present state. A letter from Joseph J. Heath on behalf of the Onondaga Nation dated October 18, 2007 expressed the following additional comments: Comment 17: Alternative 7 will do little to protect the groundwater, surface water, or human health. Response 17: The Department disagrees. The Department believes that Alternative 7 will be protective of human health and the environment as discussed in the ROD in Section 8. It satisfies the threshold criteria and provides the best balance of the primary balancing criteria described in Section 7.2. It will achieve the remediation goals for the site by containing the waste that creates the potential threat to public health and the environment, it will reduce infiltration of precipitation, thus reducing the potential for contaminant migration. The soil cover will also prevent direct exposures to trespassers and wildlife. Institutional controls and long term monitoring will ensure continued protectiveness. Comment 18: The proposed plan is short-sighted, in that it will not meet long-term remedial goals or long-term cost effectiveness. Considering the cost differential, rather than implementing Alternative 7 ( estimated present worth cost of $2 Million), the Department is urged to implement Alternative 6, complete excavation of the waste and off-site disposal, ( estimated present worth cost of $5. 5 Million.) Response 18: See Response 14 and Response 15, above. APPENDIXB Administrative Record Administrative Record South Hill Dump Site No. 712009 1.

GRANNIS, Commissioner ~----------------------------------------------· -----. --------------------------------------------------------------------------------------· ------------- - - - - DECLARATION STATEMENT -RECORD OF DECISION South Hill Dump Inactive Hazardous Waste Disposal Site Cortlandville, Cortland, New York Site No. 712009 Statement of Purpose and Basis The Record of Decision (ROD) presents the selected remedy for the South Hill Dump site, a Class 2 inactive hazardous waste disposal site. The selected remedial program was chosen in accordance with the New York State Environmental Conservation Law and is not inconsistent with the National Oil and Hazardous Substances Pollution Contingency Plan of March 8, 1990 (40CFR300), as amended. This decision is based on the Administrative Record of the New York State Department of Environmental Conservation (the Department) for the South Hill Dump inactive hazardous waste disposal site, and the public's input to the Proposed Remedial Action Plan (PRAP) presented by the Department. A listing of the documents included as a part of the Administrative Record is included in Appendix B of the ROD. Assessment of the Site Actual or threatened releases of hazardous waste constituents from this site, if not addressed by implementing the response action selected in this ROD, presents a current or potential significant threat to public health and/or the environment. Description of Selected Remedy Based on the results of the Remedial Investigation and Feasibility Study (RI/FS) for the South Hill Dump site and the criteria identified for evaluation of alternatives, the Department has selected a two foot soil cover over the waste mass. The components of the remedy are as follows: 1. A remedial design program would be implemented to provide the details necessary for the construction, operation, maintenance, and monitoring of the remedial program. 2. A soil cover would be constructed over all fill areas to prevent exposure to contaminated soils and minimize percolation. The soil cover would consist of eighteen (18) inches of clean fill and six inches of topsoil. Vegetation would be established, and runoff control devices would be constructed to reduce erosion. 3. Imposition of an institutional control in the form of an environmental easement that would require (a) compliance with the approved site management plan; (b) restricting the use of i groundwater as a source of potable or process water, without necessary water quality treatment as determined by NYSDOH; and ( c) the property owner or person implementing the remedy to complete a periodic certification of institutional and engineering controls. 4. Development of a site management plan which would include the following institutional and engineering controls: (a) management of the final cover system to maintain the cover and restrict excavation in the cover area; (b) environmental monitoring including groundwater, surface water, and sediment; ( c) identification of any use restrictions on the site and ( d) provisions for the continued proper operation and maintenance of the components of the remedy. 5. The property owner or the person implementing the remedy would provide a periodic certification of institutional and engineering controls, prepared and submitted by a professional engineer or such other expert acceptable to the NYSDEC, until the NYSDEC notifies them in writing that this certification is no longer needed. This submittal would: (a) contain certification that the institutional controls and engineering controls put in place are still in place and are either unchanged from the previous ce1tification or are compliant with NYSDEC-approved modifications; (b) allow the NYSDEC access to the site; and (c) state that nothing has occurred that would impair the ability of the control to protect public health or the environment, or constitute a violation or failure to comply with the site management plan unless otherwise approved by the NYSDEC. New York State Department of Health Acceptance The New York State Department of Health (NYSDOH) concurs that the remedy selected for this site is protective of human health. Declaration The selected remedy is protective of human health and the environment, complies with State and Federal requirements that are legally applicable or relevant and appropriate to the remedial action to the extent practicable, and is cost effective. This remedy utilizes permanent solutions and alternative treatment or resource recovery technologies, to the maximum extent practicable, and satisfies the preference for remedies that reduce toxicity, mobility, or volume as a principal element.

B-1 iii RECORD OF DECISION South Hill Dump Site Cortlandville, Cortland, New York Site No.712009 January,2008 SECTION 1: SUMMARY OF THE RECORD OF DECISION The New York State Department of Environmental Conservation (NYSDEC), in consultation with the New York State Department of Health (NYSDOH), has selected this remedy for the South Hill Dump. The presence of hazardous waste has created significant threats to human health and/or the environment that are addressed by this remedy. As more fully described in Sections 3 and 5 of this document, the site was a municipal disposal facility for the Town of Cortlandville from the early 1960's until 1972, although it is reported that local residents used the site for trash disposal as early as 1949 and there is evidence of industrial disposal. These wastes have contaminated the groundwater, surface water, and soils at the site, and have resulted m: a significant threat to human health associated with potential exposure to surface soils and exposed waste. • a significant threat to wildlife associated with potential exposure to surface water, sediments and surface soils. To eliminate or mitigate these threats, the NYSDEC has selected the installation of a soil cover system over the disposal area, establish vegetation, and apply institutional controls. The selected remedy, discussed in detail in Section 8, is intended to attain the remediation goals identified for this site in Section 6. The remedy must conform with officially promulgated standards and criteria that are directly applicable, or that are relevant and appropriate. The selection of a remedy must also take into consideration guidance, as appropriate. Standards, criteria and guidance are hereafter called SCGs. SECTION 2: SITE LOCATION AND DESCRIPTION The South Hill Dump consists of approximately 2.5 acres in a rnral portion of the Town of Cortlandville, Cortland County, on a six (6) acre property, and is su1Tounded by woodlands (see Figure 1 ). The site is approximately 1.25 miles from Route 81. Much of the property is steeply sloped. The smrnunding prope1iies are either used for farming or are forest. The nearest South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 Page 1 residence is approximately 0.25 mile away. The dump operated from the early 1960's until 1972 and received wastes from suffounding communities and local industries. The site is located in an upland area of the Tioughnioga River valley. The Tioughnioga River flows south from the City of Cortland where five valleys converge. The river flows southeast from the Cortland area approximately 30 miles, where it joins the Chenango River and eventually the Susquehanna River. The Tioughnioga is one of five major tributaries to the Susquehanna in New York State and the site falls within the Susquehanna River basin, which covers 6,100 square miles in New York. The basin is characterized by highly productive, deep stratified drift aquifers in its valleys. The site and suffounding area also overlie a 25-square mile USEP A designated sole-source aquifer system. The Cortland-Homer-Preble Aquifer System has also been designated by the NYSDEC as a primary aquifer. SECTION 3: SITE HISTORY 3.1: Operational/Disposal History The site was operated as a municipal disposal facility by the Town of Cortlandville from the early l 960's until 1972, although it is reported that local residents used the site for trash disposal as early as 1949. During its years of operation, wastes were received from the Village of McGraw and the Towns of Cortlandville and Solon, as well as local industry. Access to the site was reportedly unrestricted. It has also been reported that waste was often allowed to bum during landfill operation, and that at one time a waste oil pit may have existed. Operations are reported to have involved pushing waste over the working face of the landfill with some spreading and compaction. Cover material was reportedly spread one or more times per week. Presently, waste is protruding from the surface of the landfill across much of the site, and includes road construction debris, brush, stumps, tires, white metal, automobile parts, and miscellaneous industrial waste materials. Numerous decomposed drums are present across many areas of the landfill. 3.2: Remedial History In 1991, the NYSDEC listed the site as a Class 2 site in the Registry oflnactive Hazardous Waste Disposal Sites in New York. A Class 2 site is a site where hazardous waste presents a significant threat to the public health or the environment and action is required. In 1990, the NYSDEC conducted a site inspection and collected soil and leachate samples. Analysis revealed the presence of solvents and pesticides. Based on this data, the observed condition of the landfill (leachate seeps, numerous drum carcasses, etc.) and the reported disposal history, the site was proposed for listing on the New York State Registry oflnactive Hazardous Waste Disposal sites. South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 Page2 In response to site findings, the NYSDEC performed an interim remedial measure (IRM) drum removal. In March of 1991, five drums of hazardous waste were removed from the site. Analysis revealed that the drums contained trichloroethene (TCE). The waste was disposed at Frontier Chemical in Niagara Falls, NY. In 1991 and 1992, the Cortland County Planning Department (CCPD) collected several surface water samples at the site. The samples were collected from the intermittent stream at the toe of the landfill. Analytical data revealed elevated concentrations of the solvents TCE and dichloroethene (DCE). In the 1991 sampling event, a concentration of 200 parts per billion (ppb) of each of these compounds was detected. In 1994, the NYSDEC collected two surface water samples, three sediment samples and three soil samples from the site. Data revealed the presence ofTCE and DCE in surface water at levels slightly above the NYSDEC standards, criteria and guidance (SCG) values. These two samples were collected in immediate proximity to the CCPD samples. One sediment sample contained a low concentration (9 ppb) ofTCE. A low concentration of PCBs (79 ppb) was also detected in one sediment sample below the applicable SCG. The sediment sample results also revealed slightly elevated concentrations of several metals including copper, mercury, nickel and zinc. Analysis of the soil samples revealed low concentrations of TCE, cadmium, copper and several polyaromatic hydrocarbons. SECTION 4: ENFORCEMENT STATUS Potentially Responsible Parties (PRPs) are those who may be legally liable for contamination at a site. This may include past or present owners and operators, waste generators, and haulers. The PRPs for the site, documented to date, include: • Town of Cortlandville • Smith Corona • Overhead Doors The PRPs declined to implement the RI/FS at the site when requested by the NYSDEC. After the remedy is selected, the PRPs will again be contacted to assume responsibility for the remedial program. If an agreement cannot be reached with the PRPs, the NYSDEC will evaluate the site for fmiher action under the State Superfund. The PRPs may be subject to legal actions by the state for recovery of all response costs the state has incmTed. SECTION 5: SITE CONTAMINATION A remedial investigation/feasibility study (RI/FS) has been conducted to evaluate the alternatives for addressing the significant threats to human health and the environment. 5.1: Summary of the Remedial Investigation South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE3 The purpose of the RI was to define the nature and extent of any contamination resulting from previous activities at the site. The RI field work was conducted between August 1996 and July 2003. The field activities and findings of the investigation are described in the RI report. The RI included the following activities: • A records search was conducted to identify the site history, past operations and probable contaminants of concern. The literature search involved a review and compilation of all available State, County and Town records which pertain to the site. • A site base map was developed which illustrates the site contours, roadways, property boundaries and sample points. • A test pit investigation was conducted to visually delineate the extent of subsurface contamination and characterize the shallow overburden geology. Subsurface samples were collected to identify the nature of the contamination present. • Sediment and surface water samples were collected from visible seeps and from the intermittent stream located at the toe of the landfill. • Monitoring wells were installed in overburden and bedrock to characterize site geology and hydrogeology. Groundwater samples were collected and analyzed to identify any site impacts to groundwater. A Fish and Wildlife Impact Analysis was conducted to identify existing or potential impacts to fish and wildlife. Applicable Standards, Criteria, and Guidance (SCGs) were reviewed and compared to on site contaminant levels to assess the threat posed, if any, by the site. 5.1.1: Standards, Criteria, and Guidance (SCGs) To determine whether the soil, sediment, surface water and groundwater contain contamination at levels of concern, data from the investigation were compared to the following SCGs: • Groundwater, drinking water, and surface water SCGs are based on the NYSDEC's "Ambient Water Quality Standards and Guidance Values" and Part 5 of the New York State Sanitary Code. Soil SCGs are based on the NYSDEC's Cleanup Objectives ("Technical and Administrative Guidance Memorandum [TAGM] 4046; Determination of Soil Cleanup Objectives and Cleanup Levels.") and 6 NYCRR Subpart 375-6 -Remedial Program Soil Cleanup Objectives. South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE4 • Sediment SCGs are based on the NYSDEC's "Technical Guidance for Screening Contaminated Sediments." Based on the RI results, in comparison to the SCGs and potential public health and environmental exposure routes, certain media and areas of the site require remediation. These are summarized in Section 5.1.2. More complete information can be found in the RI report. 5.1.2: Nature and Extent of Contamination This section describes the findings of the investigation for all environmental media that were investigated. As described in the RI report, many soil, groundwater and sediment samples were collected to characterize the nature and extent of contamination. As summarized in Table 1, the main categories of contaminants that exceed their SCGs are volatile organic compounds (VOCs), pesticides, and inorganics (metals). For comparison purposes, where applicable, SCGs are provided for each medium. Chemical concentrations are reported in parts per billion (ppb) for water and parts per million (ppm) for waste, soil, and sediment. Table 1 summarizes the degree of contamination for the contaminants of concern in groundwater, surface water, surface soils and sediments and compares the data with the SCGs for the site. The following are the media which were investigated and a summary of the findings of the investigation. Investigations consisted of excavation of test pits to collect subsurface soil samples, installation of monitoring wells both above and in the bedrock to collect groundwater samples, and collection of surface water and sediment samples. No surface soil samples were collected. Chemical analysis has revealed the presence of contamination in subsurface soils, sediment, surface water and groundwater. In each sample submitted for inorganic analysis, at least one analyte was detected above SCG levels. The presence of inorganic compounds is typical of solid waste landfills. Several SVOCs were detected at concentrations above SCGs in soil samples collected during the test pit program. Benzo(a)pyrene, benzo(a)anthracene and chrysene were detected above SCGs. Phenol was also detected above SCGs in several test pit soil samples. SVOC concentrations did not exceed SCGs in soil boring samples or sediment, and in general were found at concentrations less than 1 ppm. SVOCs did not exceed SCGs in surface water or groundwater, with the exception of bis(2-ethylhexyl)phthalate, which was detected above SC Gs in five of the six surface water samples. VOC's detected during the RI included tetrachloroethylene (PCE), TCE, DCE, vinyl chloride, and BTEX compounds (benzene, toluene, ethylbenzene and xylene). These compounds were detected in groundwater, sediment and soil borings. South Hill Dwnp Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGES The only pesticide detected above the SCGs was 4,4-DDT. It was detected in test pit soils and sediments. Waste Materials Potential source areas are believed to be confined within the limits of the landfill waste, an area of approximately 2.5 acres. Waste identified during the RI/FS will be addressed in the remedy selection process. Surface and Subsurface Soils Figure 3 depicts the estimated extent oflandfill materials based upon the RI Test Pit Investigation results. According to the RI, dumping activities were confined to about 2.5 acres of the site. Concentrations of chrysene and phenol exceed SCGs in soil at five test pit locations within the landfill area. Concentrations of metals such as lead and zinc exceeded the SCGs at almost all locations. Sample locations are shown on Figure 2. The location of surface debris observed during an April 2005 site walk is also indicated on Figure 3. Site surface debris will also be considered during the development of remedial alternatives for soil. Surface and subsurface soil contamination identified during the RI/FS will be addressed in the remedy selection process. Surface Water and Sediments Sediment contamination exceeding SCGs is present at all sediment sample locations at the edge of the landfill's waste disposal area. However, all samples collected at the perimeter of the property were below SCGs. Sample locations are shown on Figure 2. Surface water contamination exceeding SCGs is present at surface water sample locations SW002 through SW006. Surface water and sediment samples were collected from the ditch along the eastern boundary of the site. This ditch receives flow from the roadside ditch and culvert via the swale in the northern portion of the site, surface runoff from the landfill area, and groundwater (leachate) seeps located along the southeastern edge of the landfill area. The entire length of this drainage is approximately 1,040 feet, from the culvert at South Hill Road to where the ditch leaves the site to the southeast. Surface water and sediment contamination identified during the RI/FS will be addressed in the remedy selection process. Groundwater Groundwater samples were collected on May 22, 1997. The analytical data showed elevated levels of several volatile compounds including DCE and TCE in both MW-3S and MW-3B. These wells are located at the toe of the landfill. The concentrations ofDCE and TCE in MW-3S were 18 ppb and 80 ppb, respectively. The concentrations ofDCE and TCE in MW-3B were 56 ppb and 540 ppb, respectively. Wells 2D, 2B, 2S, 4S and 4B which are further away from the waste mass show no exceedances of SCGs. No semi volatile compounds, or pesticides were detected above groundwater standards in any of the wells. South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE6 Several inorganic compounds were detected above groundwater standards during the 1997 sampling. Aluminum, cobalt, iron, manganese, vanadium and sodium were observed above groundwater quality standards. When compared to the background concentrations of the compounds, as observed in upgradient monitoring wells MW-lS and MW-lB, only iron and sodium were elevated in concentration. A concentration of iron of 47,600 ppb was observed in well MW-2B versus the background concentration, as observed in MW-lB, of 21,400 ppb. The groundwater quality standard is 300 ppb. Concentrations of sodium in wells MW-3S and MW-3B of 20,900 ppb and 23,600 ppb, respectively, were slightly elevated when compared to the groundwater standard of 20,000 ppb. Additional groundwater samples were collected in September of 2001. The analytical data showed elevated levels of several volatile compounds including DCE and TCE in both MW-3 S and MW-3B. The concentrations of DCE and TCE in MW-3S were 264 ppb and 200 ppb, respectively. The concentrations of DCE and TCE in MW-3B were 97 ppb and 360 ppb, respectively. Again, no semi volatile compounds or pesticides were detected above groundwater standards in any of the wells and the wells at the site boundary were below SCGs for volatiles. Groundwater contamination identified during the RI/FS will be addressed in the remedy selection process. 5.2: Interim Remedial Measures An interim remedial measure (IRM) is conducted at a site when a source of contamination or exposure pathway can be effectively addressed before completion of the RI/FS. In response to site observations, the NYSDEC performed an IRM drum removal program before starting the RI. The purpose of the program was to characterize the contents of drums observed to contain product, and properly dispose of these drums. In March of 1991, five drums were removed from the site. Analysis revealed that the drums contained TCE. An additional IRM was performed during the RI Test Pit Investigation. Excavation ofTP-40 was terminated when water reportedly containing non aqueous phase liquids (NAPL) was observed flowing into the hole. TP-40 is located at the site's eastern edge near the area where the five drums of waste containing TCE were removed in 1991. Drums and drum remnants were also observed to be present, but all the drums appeared to be empty. The area was fenced off, sorbent pads were applied to contain the liquids and a spill response contractor was procured. On March 17, 1997, the contractor pumped 660 gallons of liquid into a tanker truck. Samples were collected for analysis to characterize the liquid for off-site disposal. Analysis revealed the presence of DCE, TCE, vinyl chloride, acetone, methylphenol and several inorganics including calcium, iron, magnesium and potassium. 5.3: Summary of Human Exposure Pathways: This section describes the types of human exposures that may present added health risks to persons at or around the site. A more detailed discussion of the human exposure pathways can be found in Section 5 .3 of the RI report. An exposure pathway describes the means by which an individual may South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE? be exposed to contaminants originating from a site. An exposure pathway has five elements: [1] a contaminant source, [2] contaminant release and transport mechanisms, [3] a point of exposure, [ 4] a route of exposure, and [ 5] a receptor population. The source of contamination is the location where contaminants were released to the environment (any waste disposal area or point of discharge). Contaminant release and transport mechanisms carry contaminants from the source to a point where people may be exposed. The exposure point is a location where actual or potential human contact with a contaminated medium may occur. The route of exposure is the manner in which a contaminant actually enters or contacts the body ( e.g., ingestion, inhalation, or direct contact). The receptor population is the people who are, or may be, exposed to contaminants at a point of exposure. An exposure pathway is complete when all five elements of an exposure pathway exist. An exposure pathway is considered a potential pathway when one or more of the elements currently does not exist, but could in the future. Current complete exposure pathways are limited to direct contact by trespassers with contaminated sediment and exposed waste. Exposed waste, such as construction debris and white-goods, may also present a physical hazard. Because of the site's remote location, current exposure pathways involving other media are not complete. Potential future exposure pathways include direct contact with sediment, surface and subsurface soil by on-site remedial workers. The remedy will prohibit future consumption of contaminated groundwater on site and soil vapor intrusion into occupied structures from volatilization of compounds in the groundwater will also not occur, as no structures will be allowed. The potential exposure to contaminated groundwater or soil vapor downgradient of the site in the future is unlikely because of the proximity of the site boundary to the unnamed stream. 5.4: Summary of Environmental Assessment This section summarizes the assessment of existing and potential future environmental impacts presented by the site. Environmental impacts include existing and potential future exposure pathways to fish and wildlife receptors, as well as damage to natural resources such as aquifers and wetlands. Analysis ofleachate, stained soil, sediment and surface water has revealed the primary contaminants of concern are solvents and pesticides. Low levels of metals such as arsenic, copper, lead and cadmium were also detected in surface water subsurface soils and sediments. Semivolatile contaminants including benzo(a)pyrene, benzo(a)anthracene, phenol and chrysene were also detected in sub-surface soils and these detections may be evidence that burning of the waste occmred. Investigations indicate the landfill is contaminating the groundwater and an intermittent stream at the toe of the landfill. Field observations and analytical results from environmental samples indicate that groundwater, surface soil, surface water, and sediment are potential complete exposure pathways for wildlife located on and downgradient of the site. Chemicals disposed on-site were detected in leachate South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGES (groundwater), surface water, and sediment samples. However, field observations and sample results indicate that ecologically significant migration of chemicals in surface water and sediment to the unnamed stream south of the site is unlikely. Concentrations in downgradient groundwater, surface water, and sediment samples collected near the site property line (approximately 500 feet from the landfill area) were near or below analytical detection limits. Furthermore, little aquatic vegetation was observed in the stream during the site visit, and the bottom sediment consists mostly of a mixture of rock and gravel with very little organic content. The following environmental exposure pathways and ecological risks have been identified: Site contamination has the potential to impact the groundwater resource in the Cmiland-Homer- Preble aquifer system. The Cortland-Homer-Preble Aquifer System has also been designated by the NYSDEC as a primary aquifer. The site is situated at the eastern edge of this aquifer system. SECTION 6: SUMMARY OF THE REMEDIATION GOALS Goals for the remedial program have been established through the remedy selection process stated in 6 NYCRR Part 375. At a minimum, the remedy selected must eliminate or mitigate all significant threats to public health and/or the environment presented by the hazardous waste disposed at the site through the proper application of scientific and engineering principles. The remediation goals for this site are to eliminate or reduce to the extent practicable: • exposures of persons and wildlife at or around the site to waste, sediment and surface soil; • the release of contaminants from the waste into groundwater that may create exceedances of groundwater quality standards; • prevent releases of contaminants from the waste that would result in surface water levels in excess of ambient water quality criteria. Further, the remediation goals for the site include attaining to the extent practicable: • ambient groundwater quality standards and • soil cleanup standards. SECTION 7: SUMMARY OF THE EVALUATION OF ALTERNATIVES The selected remedy must be protective of human health and the environment, be cost-effective, comply with other statutory requirements, and utilize permanent solutions, alternative technologies or resource recovery technologies to the maximum extent practicable. Potential remedial alternatives for the South Hill Dump were identified, screened and evaluated in the FS report which is available at the document repositories established for this site. South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE9 A summary of the remedial alternatives that were considered for this site is discussed below. The present worth represents the amount of money invested in the cunent year that would be sufficient to cover all present and future costs associated with the alternative. This enables the costs of remedial alternatives to be compared on a common basis. As a convention, a time frame of30 years is used to evaluate present worth costs for alternatives with an indefinite duration. This does not imply that operation, maintenance, or monitoring would cease after 30 years if remediation goals are not achieved. 7 .1: Description of Remedial Alternatives The following potential remedies were considered to address the contaminated soils, sediments, surface water and groundwater at the site. Alternative 1: No Further Action The No Further Action alternative recognizes remediation of the site conducted under previously completed IRMs. To evaluate the effectiveness of the remediation completed under the IRMs, only continued monitoring is necessary. This alternative would leave the site in its present condition and would not provide any additional protection to human health or the environment. Alternative 2: Limited Action Present Worth: ........................................................ $1,391,000 Capital Cost: .......................................................... $182,000 Annual Costs: (Years 1-5): ........................................................... $114,000 (Years 6-10): ........................................................... $63,000 (Years 11-30): .......................................................... $38,000 This alternative includes institutional controls, engineering controls and long term environmental monitoring. Institutional controls include implementing land-use restrictions to limit site access, prohibit subsurface activity and installation of drinking water wells in the area of contamination. Land-use restrictions would be implemented through environmental easements. The existing site fence would be expanded to encompass the entire property and warning signs will be posted. Long-term maintenance of fencing and warning signs are included in the alternative. Surface and ground water would be monitored quarterly. After five years, the frequency of monitoring could be reduced from quarterly to annual. Construction of the fence could be completed in three months. South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE IO Alternative 3: 6 NYCRR 360 CAP Present Worth: ........................................................ $3,147,000 Capital Cost: ......................................................... $1,492,000 Annual Costs: (Years 1-5): ........................................................... $147,000 (Years 6-10): ........................................................... $96,000 (Years 11-30): .......................................................... $71,000 This alternative would cap the landfill with a cover compliant with current 6 NYCRR Part 360 regulations, including a gas venting layer, impermeable cover liner, barrier protection layer and topsoil. The site would be fenced. Institutional controls and long term environmental monitoring would be necessary. Pre-design investigations would be conducted to provide site-specific data needed to conduct final design of the remedial actions. The investigations would include a shallow test pit investigation to identify the extent of landfill materials at the site. Once the extent of the landfill materials is identified, bulky metal surface debris would either be removed and potentially recycled, or crushed and consolidated at the base of the landfill tier embankments. The presence of steep embankment slopes at the edge of the landfill tiers would require placement of clean fill materials and/or regrading to provide a stable slope for cover system construction. The cap would greatly reduce percolation of precipitation into the waste mass, thereby reducing leachate generation and contaminant migration. Construction of the cover system would require rerouting of the drainage ditch to an area beyond the toe of the constructed cover system. To address potential landfill leachate, the cover system would include a leachate collection system. The leachate collection system would consist of a toe drain with subsurface drain pipes along the downgradient perimeter of the landfill material to collect leachate. The leachate would be drained to a central location for collection and proper off-site disposal. Because contamination above SCGs would remain on site, institutional controls as described in Alternative 2 would be implemented to prevent exposure. Environmental monitoring would be similar to Alternative 2 with additional air monitoring at the perimeter (for methane as per 6 NYCRR 360.2.f.ii). The results would be used to evaluate the effectiveness and protectiveness of this alternative. After five years, the frequency of monitoring would be reduced from quarterly to annual. Maintenance activities would include periodic inspection and, if necessary, repair of the cover system and fence. The pre-design investigations would take approximately three months and the design another three. Construction of the cap could be completed in one construction season. Alternative 4: HOT SPOT REMOVAL Present Worth: ........................................................ $2, 7 40, 000 Capital Cost: ......................................................... $1,623,000 Annual Costs: (Years 1-5): ........................................................... $119,000 (Years 6-10): ........................................................... $68,000 South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE 11 (Years 11-30): .......................................................... $43,000 This alternative would entail excavation within the landfill. While no specific hot spot areas were delineated during the RI, it is known that the landfill contains drum carcasses, and some may contain residual waste. Institutional and engineering controls as well as long term environmental monitoring would be necessary. It is estimated that approximately 500 cubic yards of contaminated soil would be removed along with the drum material. Excavated soil and drums would be sampled for characterization prior to transportation for off-site disposal. Following hot spot removal, excavated areas would be backfilled with clean fill, the steeper slopes regraded and the landfill re-vegetated. Because contamination above SCGs would remain on-site, institutional controls, maintenance and environmental monitoring would be implemented similar to Alternative 2. The pre-design investigations and design would take approximately three months. Construction of the remedy could be completed in one construction season. Alternative 5: HOT SPOT REMOVAL WITH 6 NYCRR 360 CAP Present Worth: ........................................................ $4,242,000 Capital Cost: ......................................................... $2,622,000 Annual Costs: Years 1-5): ............................................................ $147,000 (Years 6-10): ........................................................... $96,000 (Years 11-30): .......................................................... $71,000 This alternative is a combination of Alternatives 3 and 4. Excavation within the landfill to locate and remove drums and contaminated soil as in Alternative 4 would be followed by consolidation and capping of the landfill as in Alternative 3. Since portions of the landfill would be excavated to determine the locations ofhot spots, consolidation could provide significant savings over Alternative 3 by reducing the footprint of the landfill. Because contamination above SCGs would remain on- site, institutional controls, maintenance and environmental monitoring would be implemented similar to Alternative 3. Design efforts would take approximately three months and construction could be completed in one construction season. Alternative 6 :EXCAVATION OF ENTIRE LANDFILL AND DISPOSAL AT AN OFF- SITE LOCATION Present Worth: ........................................................ $5,507,000 Capital Cost: ......................................................... $4,989, 000 Annual Costs: (Years 1-5): ........................................................... $107,000 (Years 6-30): ............................................................ $5,000 South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE12 This alternative includes excavation and off-site disposal of the entire landfill. Excavated soil, sediment, and waste would be sampled for characterization prior to transportation for off-site disposal. Waste excavation, handling, and staging would be conducted similar to Alternative 4. After excavation, some limited environmental monitoring would be necessary to ensure that all the waste had been removed. The pre-design investigations would take approximately three months. Excavation of the landfill could be completed in two construction seasons. Alternative 7 :TWO FOOT SOIL COVER OVER THE LANDFILL Present Worth: ........................................................ $2, 040, 000 Capital Cost: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $888, 000 Annual Costs: (Years 1-5): ........................................................... $121,000 (Years 6-10): ........................................................... $70,000 (Years 11-30): .......................................................... $45,000 This alternative would "close" the landfill in compliance with 6 NYCRR Part 360 requirements in effect at the time the landfill was last used for waste disposal. Scrap metal on the surface would be removed and recycled or disposed off-site. A two foot soil cover would be placed over the entire landfill to prevent wildlife or trespasser contact with waste currently exposed at the surface. The landfill will be regraded during the cover installation, vegetation would be established, and the drainage ditch would be re-routed to an area beyond the toe of the constructed cover system. These actions will reduce infiltration of precipitation through the waste mass and reduce contaminant migration. Institutional and engineering controls, land use restrictions and long term monitoring of groundwater, surface water and sediment would be performed to verify the effectiveness of the remedy at reducing infiltration. Maintenance activities would include periodic inspection and, if necessary, repair of the cover system. The pre-design investigations would take approximately three months and the design another three. Construction of the soil cover could be completed in one construction season. 7.2 Evaluation of Remedial Alternatives The criteria to which potential remedial alternatives are compared are defined in 6 NYC RR Part 3 7 5, which governs the remediation of inactive hazardous waste disposal sites in New York A detailed discussion of the evaluation criteria and comparative analysis is included in the FS report. The first two evaluation criteria are termed "threshold criteria" and must be satisfied in order for an alternative to be considered for selection. 1. Protection of Human Health and the Environment. This criterion is an overall evaluation of each alternative's ability to protect public health and the environment. 2. Compliance with New York State Standards, Criteria, and Guidance (SCGs). Compliance with SCGs addresses whether a remedy would meet environmental laws, regulations, and other standards South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE 13 and criteria. In addition, this criterion includes the consideration of guidance which the NYSDEC has determined to be applicable on a case-specific basis. The next five "primary balancing criteria" are used to compare the positive and negative aspects of each of the remedial strategies. 3. Short-term Effectiveness. The potential short-term adverse impacts of the remedial action upon the community, the workers, and the environment during the construction and/or implementation are evaluated. The length of time needed to achieve the remedial objectives is also estimated and compared against the other alternatives. 4. Long-term Effectiveness and Permanence. This criterion evaluates the long-term effectiveness of the remedial alternatives after implementation. If wastes or treated residuals remain on-site after the selected remedy has been implemented, the following items are evaluated: 1) the magnitude of the remaining risks, 2) the adequacy of the engineering and/or institutional controls intended to limit the risk, and 3) the reliability of these controls. 5. Reduction of Toxicity, Mobility or Volume. Preference is given to alternatives that permanently and significantly reduce the toxicity, mobility or volume of the wastes at the site. 6. Implementability. The technical and administrative feasibility of implementing each alternative are evaluated. Technical feasibility includes the difficulties associated with the construction of the remedy and the ability to monitor its effectiveness. For administrative feasibility, the availability of the necessary personnel and materials is evaluated along with potential difficulties in obtaining specific operating approvals, access for construction, institutional controls, and so forth. 7. Cost-Effectivness. Capital costs and annual operation, maintenance, and monitoring costs are estimated for each alternative and compared on a present worth basis. Although cost-effectiveness is the last balancing criterion evaluated, where two or more alternatives have met the requirements of the other criteria, it can be used as the basis for the final decision. The costs for each alternative are presented in Table 2. - This final criterion is considered a "modifying criterion" and is taken into account after evaluating those above. It is evaluated after public comments on the Proposed Remedial Action Plan have been received. 8. Community Acceptance -Concerns of the community regarding the Rl/FS reports and the PRAP have been evaluated. The responsiveness summary (Appendix A) presents the public comments received and the manner in which the NYSDEC addressed the concerns raised. In general, the public comments received were supportive of the selected remedy. Several comments were received, however, pertaining to continued releases from the landfill and the need to remove the landfill in its entirety. South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGEl4 SECTION 8: SUMMARY OF THE SELECTED REMEDY Based on the Administrative Record (Appendix B) and the discussion presented below, the NYSDEC has selected Alternative 7, a two foot soil cover over the landfill with long term monitoring and institutional controls, as the remedy for this site. The specific elements of this remedy are described at the end of this section. The selected remedy is based on the results of the RI and the evaluation of alternatives presented in the FS. Alternative 7 is being selected because, as described below, it satisfies the threshold criteria and provides the best balance of the primary balancing criteria described in Section 7 .2. It will achieve the remediation goals for the site by covering the exposed waste mass to prevent direct exposure to the waste. By regrading the landfill, installing a proper cover, and reconfiguring an intermittent stream which carries rainwater from upgradient of the landfill, the amount of water passing through the waste mass will be reduced, which will reduce the potential for waste migration. A post- remedial monitoring program will confirm the effectiveness of the remedial approach. Any changes in the groundwater quality or any indication of contaminant migration from the landfill would be detected by the environmental monitoring program. In such a case, any need for additional investigations and remedial actions would be evaluated. Because contamination above SCGs will remain on site, institutional controls will be implemented. Neither Alternative 1 nor Alternative 2 meets the threshold criteria for protecting human health and the environment because they do not protect trespassers and wildlife from direct contact to exposed waste. In addition to Alternative 7, Alternative 3 (6 NYCRR PART 360 CAP), Alternative 4 (HOT SPOT REMOVAL), Alternative 5 (HOT SPOT REMOVAL WITH 6 NYCRR 360 CAP), and Alternative 6 (EXCAVATION OF ENTIRE LANDFILL) also comply with the threshold criteria. Therefore, the five balancing criteria are paiiicularly important in selecting a final remedy for the site. Alternative 7 will have some controllable short te1m adverse impacts, including dust generation during construction and increased truck traffic. However, all alternatives which comply with the threshold criteria would have short term impacts to some degree. Alternatives 3, 4, 5 and 6 would have more significant adverse impacts, since both dust and truck traffic would be increased. All of the alternatives are readily implementable using standard construction techniques. The cost analysis for all alternatives is presented in Table 2, which details the capital cost, annual cost and total present worth cost for each alternative (based on a 5% discount rate). Ultimately the volume and toxicity of the waste is expected to decrease under all the alternatives as the waste decomposes and natural attenuation breaks down the chemical constituents. Alternative 6 would provide reduction of the waste on site, and Alternatives 3, 5 and 7 will reduce exposure to the waste by covering the landfill as well as reduce potential contaminant mobility by decreasing infiltration. South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE 15 Alternatives 4 and 5 focus on "hot spot" removal. However, the remedial investigation did not locate or define any hot spots that may remain in the landfill. Therefore, these two alternatives involve significant additional short term impacts and cost without providing any confidence that the level of protectiveness is any greater than Alternatives 3 and 7, respectively, which describe similar remedies but without further attempts toward locating potential hot spots for removal. Alternative 3 is similar to Alternative 7 except Alternative 3 includes a cap that would effectively eliminate infiltration of precipitation into the landfill, whereas Alternative 7 includes a cover which will be designed to reduce infiltration. Infiltration can increase the risk of waste mobilization. However, the results of the remedial investigation indicate that even in the landfill's current state, waste mobilization does not appear to be impacting the off-site environment. The increased short- term impacts and cost ofimplementing Alternative 3, when compared to Alternative 7, do not appear warranted. Alternative 6 would provide the best long term effectiveness and permanence, since the entire landfill would be excavated and disposed off site. However, this would create a substantial rise in the short term impacts and cost of the remedy. The very significant complications created by implementing Alternative 6 -the potential impacts to human health and the environment caused by excavating, loading and transporting the entire landfill -do not appear wmrnnted by current conditions. On the basis of the rationale outlined in this section, Alternative 7 - a two foot soil cover over the landfill with long term monitoring and institutional controls -is the Department's preferred remedy for the South Hill Dump. The elements of the selected remedy are as follows: 1. A remedial design program will be implemented to provide the details necessary for the construction, operation, maintenance, and monitoring of the remedial program. 2. A soil cover will be constructed over all fill areas to prevent exposure to contaminated soils and minimize percolation. The soil cover will consist of eighteen ( 18) inches of clean fill and six inches of topsoil. Vegetation will be established, and rnnoff control devices will be constructed to reduce erosion. 3. Imposition of an institutional control in the form of an environmental easement that will require (a) compliance with the approved site management plan; (b) restricting the use of groundwater as a source of potable or process water, without necessary water quality treatment as determined by NYSDOH; and ( c) the property owner or person implementing the remedy to complete a periodic certification of institutional and engineering controls. 4. Development of a site management plan which will include the following institutional and engineering controls: (a) management of the final cover system to maintain the cover and restrict excavation in the cover area; (b) environmental monitoring including groundwater, surface water, and sediment; ( c) identification of any use restrictions on the site and ( d) South Hill Dump Inactive Hazardous Waste Disposal Site RECORD OF DECISION January 2008 PAGE16 provisions for the continued proper operation and maintenance of the components of the remedy. 5. The prope1iy owner or the person implementing the remedy will provide a periodic certification of institutional and engineering controls, prepared and submitted by a professional engineer or such other expert acceptable to the NYSDEC, until the NYSDEC notifies them in writing that this certification is no longer needed. This submittal will:(a) contain certification that the institutional controls and engineering controls put in place are still in place and are either unchanged from the previous certification or are compliant with NYSDEC-approved modifications; (b) allow the NYSDEC access to the site; and (c) state that nothing has occurred that will impair the ability of the control to protect public health or the environment, or constitute a violation or failure to comply with the site management plan unless otherwise approved by the NYSDEC. Since the remedy may result in untreated hazardous waste remaining at the site, a long-te1m monitoring program will be instituted. This program will allow the effectiveness of the landfill cover to be monitored and will be a component of the long-term management for the site. SECTION 9: HIGHLIGHTS OF COMMUNITY PARTICIPATION As part of the remedial investigation process, a number of Citizen Participation activities were undertaken to inform and educate the public about conditions at the site and the potential remedial alternatives. The following public participation activities were conducted for the site: • Repositories for documents pe1iaining to the site were established. A public contact list, which included nearby property owners, elected officials, local media and other interested parties, was established.

The CAMP is not intended for use in establishing action levels for worker respiratory protection. Rather, its intent is to provide a measure of protection for the downwind community (i.e., off-site receptors including residences and businesses and on-site workers not directly involved with the subject work activities) from potential airborne contaminant releases as a direct result of investigative and remedial work activities. The action levels specified herein require increased monitoring, corrective actions to abate emissions, and/or work shutdown. Additionally, the CAMP helps to confirm that work activities did not spread contamination off-site through the air. The generic CAMP presented below will be sufficient to cover many, if not most, sites. Specific requirements should be reviewed for each situation in consultation with NYSDOH to ensure proper applicability. In some cases, a separate site-specific CAMP or supplement may be required. Depending upon the nature of contamination, chemical- specific monitoring with appropriately-sensitive methods may be required. Depending upon the proximity of potentially exposed individuals, more stringent monitoring or response levels than those presented below may be required. Special requirements will be necessary for work within 20 feet of potentially exposed individuals or structures and for indoor work with co-located residences or facilities. These requirements should be determined in consultation with NYSDOH. Reliance on the CAMP should not preclude simple, common-sense measures to keep VOCs, dust, and odors at a minimum around the work areas. Community Air Monitoring Plan Depending upon the nature of known or potential contaminants at each site, real-time air monitoring for VOCs and/or particulate levels at the perimeter of the exclusion zone or work area will be necessary. Most sites will involve VOC and particulate monitoring; sites known to be contaminated with heavy metals alone may only require particulate monitoring. If radiological contamination is a concern, additional monitoring requirements may be necessary per consultation with appropriate DEC/NYSDOH staff. Continuous monitoring will be required for all ground intrnsive activities and during the demolition of contaminated or potentially contaminated structures. Ground intrusive activities include, but are not limited to, soil/waste excavation and handling, test pitting or trenching, and the installation of soil borings or monitoring wells. Periodic monitoring for VOCs will be required during non-intrusive activities such as the collection of soil and sediment samples or the collection of groundwater samples from existing monitoring wells. "Periodic" monitoring during sample collection might reasonably consist of taking a reading upon aiTival at a sample location, monitoring while opening a well cap or Final DER-10 Technical Guidance for Site Investigation and Remediation Page 204 of 226 May 2010 overturning soil, monitoring during well baling/purging, and taking a reading prior to leaving a sample location. In some instances, depending upon the proximity of potentially exposed individuals, continuous monitoring may be required during sampling activities. Examples of such situations include groundwater sampling at wells on the curb of a busy urban street, in the midst of a public park, or adjacent to a school or residence. VOC Monitoring, Response Levels, and Actions Volatile organic compounds (VOCs) must be monitored at the downwind perimeter of the immediate work area (i.e., the exclusion zone) on a continuous basis or as otherwise specified. Upwind concentrations should be measured at the start of each workday and periodically thereafter to establish background conditions, particularly if wind direction changes. The monitoring work should be performed using equipment appropriate to measure the types of contaminants known or suspected to be present. The equipment should be calibrated at least daily for the contaminant( s) of concern or for an appropriate surrogate. The equipment should be capable of calculating 15-minute running average concentrations, which will be compared to the levels specified below. 1. If the ambient air concentration of total organic vapors at the downwind perimeter of the work area or exclusion zone exceeds 5 parts per million (ppm) above background for the 15-minute average, work activities must be temporarily halted and monitoring continued. If the total organic vapor level readily decreases (per instantaneous readings) below 5 ppm over background, work activities can resume with continued monitoring. 2. If total organic vapor levels at the downwind perimeter of the work area or exclusion zone persist at levels in excess of 5 ppm over background but less than 25 ppm, work activities must be halted, the source of vapors identified, corrective actions taken to abate emissions, and monitoring continued. After these steps, work activities can resume provided that the total organic vapor level 200 feet downwind of the exclusion zone or half the distance to the nearest potential receptor or residential/commercial structure, whichever is less -but in no case less than 20 feet, is below 5 ppm over background for the 15-minute average. 3. If the organic vapor level is above 25 ppm at the perimeter of the work area, activities must be shutdown. 4. All 15-minute readings must be recorded and be available for State (DEC and NYSDOH) personnel to review. Instantaneous readings, if any, used for decision purposes should also be recorded. Particulate Monitoring, Response Levels, and Actions Particulate concentrations should be monitored continuously at the upwind and downwind perimeters of the exclusion zone at temporary particulate monitoring stations. The particulate monitoring should be performed using real-time monitoring equipment capable of measuring particulate matter less than 10 micrometers in size (PM-10) and capable of integrating over a period of 15 minutes (or less) for comparison to the airborne particulate action level. The equipment must be equipped with an audible alarm to indicate exceedance of the action level. In addition, fugitive dust migration should be visually assessed during all work activities. Final DER-10 Technical Guidance for Site Investigation and Remediation Page 205 of 226 May 2010 1. If the downwind PM-10 particulate level is 100 micrograms per cubic meter (mcg/m3) greater than background (upwind perimeter) for the 15-minute period or if airborne dust is observed leaving the work area, then dust suppression techniques must be employed. Work may continue with dust suppression techniques provided that downwind PM-10 particulate levels do not exceed 150 mcg/m3 above the upwind level and provided that no visible dust is migrating from the work area. 2. If, after implementation of dust suppression techniques, downwind PM-10 particulate levels are greater than 150 mcg/m3 above the upwind level, work must be stopped and a re-evaluation of activities initiated. Work can resume provided that dust suppression measures and other controls are successful in reducing the downwind PM-10 particulate concentration to within 150 mcg/m3 of the upwind level and in preventing visible dust migration. 3. All readings must be recorded and be available for State (DEC and NYSDOH) and County Health personnel to review. December 2009 Final DER-10 Technical Guidance for Site Investigation and Remediation Page 206 of 226 May 2010 Appendix lB Fugitive Dust and Particulate Monitoring A program for suppressing fugitive dust and particulate matter monitoring at hazardous waste sites is a responsibility on the remedial party performing the work. These procedures must be incorporated into appropriate intrusive work plans. The following fugitive dust suppression and particulate monitoring program should be employed at sites during construction and other intrusive activities which warrant its use: 1. Reasonable fugitive dust suppression techniques must be employed during all site activities which may generate fugitive dust. 2. Particulate monitoring must be employed during the handling of waste or contaminated soil or when activities on site may generate fugitive dust from exposed waste or contaminated soil. Remedial activities may also include the excavation, grading, or placement of clean fill. These control measures should not be considered necessary for these activities. 3. Particulate monitoring must be performed using real-time particulate monitors and shall monitor particulate matter less than ten microns (PMl 0) with the following minimum performance standards: (a) Objects to be measured: Dust, mists or aerosols; (b) Measurement Ranges: 0.001 to 400 mg/m3 (1 to 400,000 :ug/m3); (c) Precision (2-sigma) at constant temperature: +/-10 :g/m3 for one second averaging; and +/-1.5 g/m3 for sixty second averaging; (d) Accuracy: +/-5% of reading+/-precision (Referred to gravimetric calibration with SAE fine test dust (mmd= 2 to 3 :m, g= 2.5, as aerosolized); number (e) Resolution: 0.1 % ofreading or lg/m3, whichever is larger; (f) Particle Size Range of Maximum Response: 0.1-10; (g) Total Number of Data Points in Memory: 10,000; (h) Logged Data: Each data point with average concentration, time/date and data point (i) Run Summary: overall average, maximum concentrations, time/date of maximum, total number of logged points, start time/date, total elapsed time (run duration), STEL concentration and time/date occurrence, averaging (logging) period, calibration factor, and tag number; (i) Alarm Averaging Time (user selectable): real-time (1-60 seconds) or STEL (15 minutes), alarms required; (k) Operating Time: 48 hours (fully charged NiCd battery); continuously with charger; (1) Operating Temperature: -10 to 50° C (14 to 122° F); (m) Particulate levels will be monitored upwind and immediately downwind at the working site and integrated over a period not to exceed 15 minutes. 4. In order to ensure the validity of the fugitive dust measurements performed, there must be appropriate Quality Assurance/Quality Control (QA/QC). It is the responsibility of the remedial party to adequately supplement QA/QC Plans to include the following critical features: periodic instrument calibration, operator training, daily instrument performance (span) checks, and a record keeping plan. 5. The action level will be established at 150 ug/m3 (15 minutes average). While conservative, Final DER-10 Technical Guidance for Site Investigation and Remediation Page 207 of 226 May 2010 this short-term interval will provide a real-time assessment of on-site air quality to assure both health and safety. If paiiiculate levels are detected in excess of 150 ug/m3, the upwind background level must be confirmed immediately. If the working site particulate measurement is greater than 100 ug/m3 above the background level, additional dust suppression techniques must be implemented to reduce the generation of fugitive dust and corrective action taken to protect site personnel and reduce the potential for contaminant migration. Corrective measures may include increasing the level of personal protection for on-site personnel and implementing additional dust suppression techniques (see paragraph 7). Should the action level of 150 ug/m3 continue to be exceeded work must stop and DER must be notified as provided in the site design or remedial work plan. The notification shall include a description of the control measures implemented to prevent further exceedances. 6. It must be recognized that the generation of dust from waste or contaminated soil that migrates off-site, has the potential for transporting contaminants off-site. There may be situations when dust is being generated and leaving the site and the monitoring equipment does not measure PMl O at or above the action level. Since this situation has the potential to allow for the migration of contaminants off-site, it is unacceptable. While it is not practical to quantify total suspended particulates on a real-time basis, it is appropriate to rely on visual observation. If dust is observed leaving the working site, additional dust suppression techniques must be employed. Activities that have a high dusting potential-- such as solidification and treatment involving materials like kiln dust and lime--will require the need for special measures to be considered. 7. The following techniques have been shown to be effective for the controlling of the generation and migration of dust during construction activities: (a) Applying water on haul roads; (b) Wetting equipment and excavation faces; ( c) Spraying water on buckets during excavation and dumping; ( d) Hauling materials in properly tarped or watertight containers; ( e) Restricting vehicle speeds to 10 mph; (f) Covering excavated areas and material after excavation activity ceases; and (g) Reducing the excavation size and/or number of excavations. Experience has shown that the chance of exceeding the l 50ug/m3 action level is remote when the above-mentioned techniques are used. When techniques involving water application are used, care must be taken not to use excess water, which can result in unacceptably wet conditions. Using atomizing sprays will prevent overly wet conditions, conserve water, and provide an effective means of suppressing the fugitive dust. 8. The evaluation of weather conditions is necessary for proper fugitive dust control. When extreme wind conditions make dust control ineffective, as a last res01i remedial actions may need to be suspended. There may be situations that require fugitive dust suppression and particulate monitoring requirements with action levels more stringent than those provided above. Under some circumstances, the contaminant concentration and/or toxicity may require additional monitoring to protect site personnel and the public. Additional integrated sampling and chemical analysis of the dust may also be in order. This must be evaluated when a health and safety plan is developed and when appropriate suppression and monitoring requirements are established for protection of health and the environment.

Variations include: monitoring well sampling protocol, purge water disposal, specifications for the analytical methods used for laboratory analysis of environmental samples, and sampling identification. General Procedures and Practices. The general procedures used to conduct the Site Management Plan (SMP) scope of work at the South Hill Dump site will be taken from the following sections of the NYSDEC program QAPP: Section 2.0 Section 7.0 Section 8.0 Section 9.0 Section 11.0 Section 12.0 Section 13.0 Section 14.0 Program Organization and Responsibilities Analytical Program Data Reduction, Validation, and Reporting Internal Quality Control Preventive Maintenance Data Assessment Corrective Action Reports to Management Field Procedures and Sampling. The following field sampling procedures set forth in the program QAPP will be used at the site: QA/QC Procedures Decontamination Sample Collection and Handling Sediment Sampling Surface Water Sampling Field Instrument Calibration Section 3.0 Subsection 4.3 Sections 4.0 and 5.0 Section 4.5.5 Section 4.5.4.1 Section 6.0 The following variances to the above procedures are described in sections 1.0 to 1.3 Page 1 of5 4.2 QAPjP.docx Site Management Plan -South Hill Dump NYSDEC -Site No. 712009 MACTEC Engineering and Consulting, P.C. -3612122249 December 2015 1.0 Monitoring Well Sampling. Groundwater samples will be collected using a "no purge" sampling technique. The procedure for collecting these samples using the HydraSleeve sampler is included as Attachment 1. 1.1 Purge Water Disposal. Decontamination of equipment will follow procedures described in the QAPP except for disposal of purge water Purge water from groundwater sampling will be released on-Site to the ground surface in the area of well, so as to allow the liquids to infiltrate into the soil and not run off-Site. In the event that purge water exhibits visual or olfactory evidence of site-related contamination, fluids will be containerized for proper disposal. 1.2 Data Quality Objectives. Data Quality Objectives (DQOs) for the South Hill Dump site sampling activities are summarized in Table G-1. DQOs are described in accordance with USEPA guidelines (USEPA, 1987) and the NYSDEC ASP (NYSDEC, 2005). Analytical data requirements were established using the methods described in the ASP. Analytical methods to be used for laboratory analysis are presented in Table G-2. Analytical Category B deliverables as described in the ASP will be provided by the laboratory. A chemist review will be conducted for each batch of groundwater, sediment and surface water and the data will be submitted to the NYSDEC as an EQuIS electronic data deliverable. 1.3 Sampling Identification. Sample identification will adhere to the Site's pre-designated monitoring location IDs.

The HydraSleeve is classified as a no-purge (passive) grab sampling device designed to collect groundwater samples directly from the screened interval of a monitoring well without having to purge the well prior to sample collection. The Hydrasleeve can be used to collect representative groundwater samples for all analytes including; VOCs, SVOCs, metals, anions, dissolved gasses total dissolved solids radionuclide's, PCBs and other compounds. The sampling generally uses the following equipment/items: • Well construction data, location map, and field data from the previous sampling event, • Water level tape (0.01-ft accuracy), • HydraSleeve samplers, • Groundwater FDR, • PID, • PPE, • Sample containers and cooler (provided by the laboratory), • Ice for sample preservation, and • Clean plastic sheeting, and miscellaneous supplies. The HydraSleeve sampler consists of the following basic components; • A suspension line or tether attached to a spring tip at the top of the sampler or directly to the sampler itself. • A long (36 to 38 inches) flexible, 4-mil thick lay-flat polyethylene sample sleeve, sealed at the bottom and with a self sealing reed type polyethylene check valve at the top. • A reusable stainless steel weight with clip, which is attached to the bottom of the sample sleeve. • A discharge tube that is used to puncture the sample sleeve after it is recovered from the well so the sample can be decanted into bottles. • Just above the self sealing check valve at the top of the sleeve are two holes which provide attachment points for the spring clip or suspension line. At the bottom of the sleeve are two holes which provide attachment points for the weight clip and weight. Page I of3 4.2 QAPjP.docx Site Management Plan -South Hill Dump NYSDEC -Site No. 712009 MACTEC Engineering and Consulting, P.C. -3612122249 HydraSleeve deployment Before installing the HydraSleeve you will need to know the following; • The inside diameter of the well. • The length of the well screen. • The water level in the well. • The length and depth of the well screen. • The total depth of the well. HydraSleeve placement December 2015 The Hydrasleeve should be placed such that the stainless steel weight attached to the bottom of the sample sleeve is at the bottom of the well or within 6 inches of the bottom of the well. Procedures for sampling with the HydraSleeve • Collect well measurements including depth to water and depth to bottom of well. • Assemble the HydraSleeve • Remove HydraSleeve from its packing, unfold it and hold by its top. • Crimp the top of the HydraSleeve by folding the hard polyethylene reinforcing strips at the holes. • Attach the spring clip to the holes to insure the top remains open until the sampler is retrieved. • Attach suspension line to spring clip. Alternatively if no spring clip is used attach line to one (not both) of the holes at the top of the HydraSleeve. • Fold the flaps with the two holes at the bottom of the HydraSleeve together and slid the weight clip thru the holes. • Attach a weight to the bottom of the weight clip to insure that the HydraSleeve will descend to the bottom of the well. • Measure the suspension line so that the weight attached to the bottom of the HydraSleeve will be positioned at the bottom of the well screen. • Using the suspension line carefully lower the Hydrasleeve to the desired sample position. Make sure that the HydraSleeve is not pulled upwards at any time during installation into the well. If the HydraSleeve is pulled upward at a rate of 0.5 feet/second the top check valve will open and water will enter the HydraSleeve prematurely. • Secure the HydraSleeve sampler in place by tying off the suspension line at the top of the well. • Allow the monitoring well to equilibrate following installation of the HydraSleeve. In many cases the well will equilibrate within a few hours but the HydraSleeve can be left in place indefinitely.

December 2015 • Access the monitoring well and secure the suspension line without moving HydraSleeve. • Measure the water level. • In on smooth motion pull the suspension line (and HydraSleeve) upwards for three to five feet at a rate of 1 foot per second or faster. The motion will open the top check valve and allow the HydraSleeve to fill (it should fill after being pulled up about 1 to 1.5 times the length of the HydraSleeve). When the HydraSleeve is full the top check valve will close. You should begin to feel the weight of the HydraSleeve on the suspension line after the valve closes and the full sampler begins displace water. • Continue to pull the suspension line until the HydraSleeve is at the top of the well. • Decant and discard the small volume of water trapped in the HydraSleeve above the check valve by turning the sleeve over. • Remove the discharge tube from its packing sleeve. • Hold the HydraSleeve at the check valve. • Puncture the HydraSleeve just below the check valve with the pointed end of the discharge tube. • Discharge water from the HydraSleeve through the discharge tube into sample containers. The discharge rate can be controlled by either raising the bottom of the HydraSleeve or by squeezing it like a tube of toothpaste. Collection of Field Water Quality Parameters. After sample collection, a turbidity sample will be collected and analyzed using a HACH 2100P (or similar). The field sampling form will be completed after each well is sampled, including sample date and time (time of retrieval from the well), well sampling sequence, types of sample bottles used, sample identification numbers, preservatives used, parameters requested for analysis, and field observations of the sampling event. Finally, replace the cap and lock the well.
