(Altamont), which became Anchor QEA on December 29, 2016, completed a series of assessment activities at the Site. Per the Graham County GIS, the Site is identified by Parcel Identification Number (PIN) 566011120000612. The parcel is currently owned by Graham County. Figure 1 illustrates the general location of the Site, and Figure 2 details the Site boundaries. The Site is generally bounded by the former Stanley Furniture complex to the east, Long Creek to the west, and commercial or residential uses to the north and south. The Site consists of undeveloped, mostly cleared land. A primitive road transects the Site. A wooded area is located on the southern portions of the Site. The northern portion of the Site is occupied by a ballfield and associated bathrooms and concession building. 1.1 Site Assessment History Altamont completed a Phase I Environmental Site Assessment (Phase I ESA), dated October 13, 2016, for the Site in general accordance with the ASTM Standard Practice for Environmental Site Assessments (ASTM E1527-13). The findings of that Phase I ESA identified multiple environmental concerns associated with the Site, specifically associated with the potential for discarded industrial waste to have been placed within the Site boundaries. After completion of the Phase I ESA, Altamont was requested to complete additional assessment of the Site. Details of those assessment activities are discussed in the following sections of this report. Phase II Environmental Site Assessment 2 February 2017 2 Scope of Services In general accordance with a proposal for Site Assessment Services, dated October 31, 2016, the completed scope of work involved:  Completion of a health and safety review  Completion of a limited ground-penetrating radar (GPR) assessment  Completion of a series of test pits  Completion of a soil assessment  Completion of a groundwater assessment  Completion of a surface water and sediment assessment 2.1 Health and Safety Information Prior to initiating field activities at the Site, Altamont and subcontracted personnel participated in an initial review of the Site Health and Safety Plan. In addition, a health and safety “tailgate” meeting was held prior to completing fieldwork. 2.2 Ground-Penetrating Radar Investigation Prior to engaging in intrusive activities, Altamont contacted the North Carolina One-Call Center to identify public utilities at the Site. Due to the apparent presence of multiple utilities on and near the Site (e.g., a sanitary sewer line and power line right-of-way), a private utility locate was also completed. Altamont subcontracted with the private utility locator to clear Site boring locations using GPR. In addition to identifying utilities that may be located within proximity to proposed boring or excavation locations, Altamont also utilized GPR technology to assess the extents and depths of potential on-site buried waste. 2.3 Test Pits Once GPR activities were completed, Altamont observed and documented the completion of a series of exploratory test pits that were completed to evaluate subsurface conditions. Test pits were completed using equipment and an operator provided by Graham County. Test pit locations were selected based on results of the GPR study, identified historical concerns, and/or physical review of Site conditions (e.g., mounded or depressed surface areas). As each test pit was excavated, the surface soil was set aside and kept separate from underlying soil and/or waste material (if applicable). After completing each test pit, the excavated material was returned to the pit from which it was excavated. The segregated surface soil was then used to cover exposed waste where applicable. Thirty-six test pit locations were completed between December 1 and 2, 2016. Phase II Environmental Site Assessment 3 February 2017 Test pit locations were identified using GPS coordinates. Figure 2 shows test pits locations within the Site boundaries. Test pit locations were also marked in the field using wooden stakes and flagging. Further details pertaining to test pit observations are include on Table 1. 2.4 Soil Sampling Between December 15 and 16, 2016, Altamont observed the completion of 10 soil borings (SB-1 through SB-10 as shown on Figure 2)_ across the Site using direct push technology drilling methods. The drilling equipment was operated by a driller licensed in North Carolina. Continuous soil cores were obtained from each boring, and one representative soil sample was collected from eight of the boring locations for laboratory analysis. Soil cores were collected via dedicated Macro-Core sleeves in 5-foot intervals and were screened with a photoionization detector (PID) for organic vapor content. One soil sample from each boring location was collected from an interval exhibiting the most elevated readings on the PID or, if no elevated reading was observed, an interval determined to be most representative of Site conditions by the professional in the field. Soil borings were advanced between 10 to 15 feet below ground surface. Soil samples were collected and transferred into laboratory-supplied containers, placed on ice, and delivered to a North Carolina certified laboratory under chain-of-custody protocol to be analyzed for volatile organic compounds (VOCs) by U.S. Environmental Protection Agency (EPA) Method 8260, semivolatile organic compounds (SVOCs) by EPA Method 8270 (expanded to include pentachlorophenol), and Resource Conservation and Recovery Act (RCRA) metals using EPA Methods 6010 and 7471. 2.5 Groundwater Sampling During completion of soil sampling, as detailed in Section 2.4, Altamont observed the advancement of three of the soil borings to intersect groundwater beneath the Site. Once groundwater was encountered, the driller installed a temporary groundwater monitoring well at each of the three locations (TMW-1 through TMW-3). After completion of the temporary wells, Altamont collected one groundwater sample from each location. The first groundwater monitoring point (TMW-1) was completed at a location estimated to be topographically upgradient of the operations of the former Stanley Furniture plant. The two additional groundwater monitoring points were completed at locations estimated to be most representative of Site conditions. Temporary monitoring well locations are shown on Figure 2. Once collected, each groundwater sample was placed in laboratory-provided containers, placed on ice, and delivered to a North Carolina certified laboratory under chain-of-custody protocol. Groundwater samples were submitted for analysis of VOCs using EPA Method 8260, SVOCs using Phase II Environmental Site Assessment 4 February 2017 EPA Method 8270 (expanded to include pentachlorophenol) and RCRA metals using EPA Methods 6010 and 7471. 2.6 Surface Water and Sediment Sampling Altamont collected three surface water and sediment samples from Long Creek, which borders the Site’s western boundary. Altamont collected one sample from an area considered to be upgradient from the former operations of Stanley Furniture plant and a second sample from a location considered to be downgradient of those operations. A third sample was collected from a central location within the boundaries of Long Creek, considered to be most representative of Site conditions. Surface water samples (SW-1 through SW-3) and sediment samples (SS-1 through SS-3) were submitted for analysis of VOCs using EPA Method 8260, SVOCs using EPA Method 8270 (expanded to include pentachlorophenol), and RCRA metals using EPA Methods 6010 and 7471. Phase II Environmental Site Assessment 5 February 2017 3 Assessment Results 3.1 GPR GPR was used to clear boring locations and assess for potential subsurface features within proximity to boring locations. In addition, GPR was used to assess potential waste boundaries. A diagram showing estimated waste extents is included as Figure 2. 3.2 Test Pits Thirty-six test pits were completed across the Site. A diagram showing test pit locations is included as Figure 2, and test pit descriptions are included on Table 1. Industrial waste and/or apparent inert buried waste was identified at multiple test pit locations. 3.3 Soil Assessment Results A total of 10 soil borings (SB-1 through SB-10) were advanced during this assessment. Eight soil samples were collected from the 10 borings. Soil analytical results were then compared to the Inactive Hazardous Site Branch Preliminary Soil Remediation Goals (PSRGs). Sample locations are depicted on Figure 2. Soil analytical results are summarized on Table 2. The laboratory analytical report is included as Appendix A. Multiple sample locations exceeded protection of groundwater, residential, and industrial PSRGs. The exceedances of industrial PSRGs at sample locations SB-5, SB-6, SB-7, and SB-10 may limit future Site redevelopment opportunities without further assessment or remediation. 3.4 Groundwater Assessment Results Three temporary monitoring wells were installed at the Site and are identified as TW-1, TW-2, and TW-3. Altamont collected groundwater samples from the three temporary monitoring wells for analysis of VOCs, SVOCs, and RCRA metals. Groundwater results were compared to the North Carolina Administrative Code 02L .0202 Groundwater Quality Standards (2L standards) The location of monitoring wells TW-1 through TW-3 are shown on Figure 2. Groundwater analytical results are summarized on Table 3, and the laboratory analytical report is included as Appendix A. Impacts to groundwater were not identified above laboratory reporting limits. 3.5 Surface Water and Sediment Results Three surface water samples (SW-1 through SW-3) and three sediment samples (SS-1 through SS-3) were collected from Long Creek, bordering the Site’s western boundary. Sample locations are depicted on Figure 2. Surface water and sediment results are summarized on Tables 3 and 4. Several constituents of concern exceeded applicable laboratory reporting limits in sediment but did not Phase II Environmental Site Assessment 6 February 2017 exceed the associated regulatory standards. Assessed constituents of concern within surface water were not identified above applicable laboratory reporting limits. Phase II Environmental Site Assessment 7 February 2017 4 Summary and Conclusions 4.1 Soil Review of Site soil analytical data and observations documented during the completion of a series of test pits and soil borings have confirmed that industrial waste has been discarded and buried within the boundaries of the Site. Multiple constituents of concern exceed industrial regulatory limits, and will require further action and assessment and/or will require institutional or engineering controls to limit potential exposure to Site workers/users. Because the constituents reported in soil do not appear to have migrated to groundwater it is likely those constituents are mostly immobile. However, additional groundwater sampling may be necessary to confirm current Site conditions and potential future risk. 4.2 Groundwater and Surface Water Analysis of groundwater and surface water samples at the Site did not identify constituents of concern above laboratory reporting limits. 4.3 Sediment Analysis of sediment samples collected from Long Creek identified three VOCs, one SVOC, and several metals above laboratory reporting limits. The reported concentrations were below applicable regulatory limits.
