McDaniel Facility Management Branch Hazardous Waste Section North Carolina Department of Environmental Quality 217 West Jones Street Raleigh, North Carolina 27603 VIA ELECTRONIC MAIL Re: Targeted Soil Sampling Confirmatory Sampling Report Badin Business Park (f/k/a Alcoa - Badin Works) Badin, North Carolina EPA ID: NCD 003 162 542 Dear Mr. McDaniel: This letter documents the results of confirmation soil sampling efforts performed at the Badin Business Park facility on June 11, 2019. The sample was collected as a follow up action to the detection of a single polychlorinated biphenyl (PCB) Aroclor, Aroclor 1232, as reported in the January 28, 2019, Targeted Sampling Report (Report). A confirmation sample was collected from a location adjacent to the location previously containing the detection; no constituents were detected above laboratory detection limits. The May 31, 2018 Targeted Sampling Work Plan (Work Plan) was developed as a guidance document in support of sampling and investigative activities at the Badin Business Park LLC, formerly known as the Alcoa Badin Works facility. The Work Plan was prepared following receipt of the North Carolina Department of Environmental Quality (NCDEQ) January 31, 2018 correspondence concerning the review and conditional approval of the Investigative Work Plan for the Phase 4 and 5 Corrective Measures Study, Alcoa/Badin Landfill, and Former Ball Field, a meeting with NCDEQ personnel on May 10, 2018, and a subsequent conference call with NCDEQ personnel on May 24, 2018. NCDEQ determined that previous environmental investigations have targeted known or suspected areas of the facility where constituents of interest (COIs) were known to have been utilized. Other areas of the facility were not evaluated because they were covered by plant buildings or other obstructions, or not suspected to be impacted. The objective of the Work Plan was to provide information to assess the presence or suspected presence of COIs in soils on the facility property not previously investigated. To accomplish the objective, surface and subsurface soil samples were collected to assess soil quality conditions and to screen for the presence of potential source areas that have not been identified in previous investigations. Robert C. McDaniel Targeted Soil Sampling Confirmatory Sampling Report June 26, 2019 As reported in the January 28, 2019 Report, a single PCB Aroclor, Aroclor 1232, was detected in one shallow soil sample (ANO-SB002 (0’-1’)) at a concentration above the Protection of Groundwater Preliminary Soil Remediation Goal (PSRG) but below the Industrial PSRG. PCB Aroclors were not detected in the remaining soil samples at concentrations above either PSRG. Aroclor 1232 has not been historically detected in soil or groundwater samples. Further, Aroclor 1232 is not common to past operations and as a result the detection of Aroclor 1232 was believed to be anomalous. During a March 19, 2019 follow-up meeting with the NCDEQ Hazardous Waste Section, it was discussed that a confirmation sample should be collected from the location where the detection occurred and the sample analyzed for Aroclor 1232. On June 11, 2019, ENVIRONEERING, Inc. personnel collected a confirmation sample from a sample location (ANO-SB003 (0’-1’)) adjacent to the location previously containing the detection. No constituents were detected above laboratory detection limits. A map showing the location of the sample is provided as Figure 1. Soil sample confirmation analytical results and equipment blank analytical results are summarized in Tables 1 and 2. The laboratory report and completed chain of custody form is provided in Appendix A. Badin Business Park LLC appreciates the time and effort your office has spent on this project, and we look forward to working with you in the future.
