(Headwater), on behalf of the Former Ticar Chemical Company (Ticar Chemical), has completed indoor air assessment activities during December 2019 at 32 Old Brevard Road in Asheville, North Carolina (the Site). A Site Location Map is included as Figure 1. The Site is currently owned by Jedhy, LLC, and has been deemed eligible to participate in the North Carolina Brownfields Program (Site ID # 17041-13-011). The Site is listed as a North Carolina Department of Environmental Quality (DEQ) Inactive Hazardous Site (Site ID # NONCD0002599), under jurisdiction of the Inactive Hazardous Sites Branch (IHSB). Assessment and remedial activities have been ongoing at the Site since the late-1980s. Current assessment activities included the collection of three indoor air samples from separate locations (IA-13-19, IA-14, and IA-15) and one ambient air sample (A-4) collected from an area outside the building. These activities were performed as the first of two indoor air sampling events and were performed in general accordance with the methodology described in the Environmental Monitoring Work Plan, prepared by Headwater, and dated October 11, 2019 (Headwater 2019). The Environmental Monitoring Work Plan was approved by the DEQ-IHSB and Brownfields Program in emails sent on October 17, 2019. This is the 5th indoor air monitoring event to have been performed over a 4-year period. Former Ticar Chemical Company—Indoor Air Monitoring Report Headwater Geology 2 2 Indoor Air Monitoring Indoor air samples were collected on December 13, 2019 from an ambient air location and three main spaces in the building: • IA-13-19: the eastern portion of the warehouse • IA-14: the western portion of the warehouse • IA-15: the office space (which adjoins the western warehouse space) • A-4: outside of the building, near the door that enters the western portion of the warehouse An Indoor Air Sample Location Map is included as Figure 2. Note that, per a request from Mr. David Ramey of the DEQ-IHSB, historical sample location IA-13 (currently referred to as IA-13-19) was moved to the south, in the direction of to sub-slab soil gas sample SS-1, as far as building operations allowed. Sample locations are shown on Figure 2. Historical sample locations, as documented in the 2018 Indoor Air Monitoring Report, prepared by Anchor QEA and dated February 28, 2019 are included in Appendix A (Anchor QEA 2019). Historical data tables are also included. 2.1 Air Sampling Methodology Indoor air sampling was performed in general accordance with the DEQ’s Vapor Intrusion Guidance (DEQ 2018a). Indoor and ambient air samples were collected using 6-liter summa canisters with 8-hour minimum collection valves. Each sample was collected using a stainless- steel sampling port elevated at a representative “breathing zone” height of approximately 4 feet above the building floor (grade). At the start and finish of sample collection, the vacuum of the summa canister was recorded. Samples were collected such that each canister maintained a negative pressure. 2.2 Sample Analysis The indoor and ambient air samples were submitted to a Con-Test Analytical Laboratory, a North Carolina certified laboratory for analysis of Site constituents of concern (COCs):  tetrachloroethylene (PCE), trichloroethylene (TCE), cis-1,2-dichloroethylene (cis-DCE), trans-1,2-dichloroethylene (trans-DCE), and vinyl chloride using EPA Method TO-15. 2.3 Chemical Inventory Prior to sample collection, Headwater performed a chemical inventory by touring the Site and interviewing a representative of DeLong Equipment Company (the current tenant). DeLong Equipment Company uses the building to store, inventory, and package turbo charger components for the automotive industry. They periodically operate a parts washer onsite. The Former Ticar Chemical Company—Indoor Air Monitoring Report Headwater Geology 3 purpose of this inventory was to identify products within the building that could potentially emit chemicals into the indoor air. During the Site visit, Headwater recognized and identified six products within the Site’s building:  Rubbing alcohol (isopropyl alcohol or isopropynol)  Lubricant oil (Castrol Techniclean 3602)  Rust inhibitor (Madison Chemical Compound RP-26)  ZEP Industrial Purple Cleaner & Degreaser  Spitfire RTU Power Cleaner  Spectracide Bug Stop “Home Barrier” Containers of paint and household cleaning products were also observed on Site. Container labels were reviewed, and SDSs were located and reviewed for the products observed. Review of the SDSs of these products indicated the following chemicals in each product:  Castrol Techniclean 3602 – Contains between 10% and 25% triethanolamine  Madison Chemical Compound RP-26 – Contains between 70% and 80% hydrotreated light petroleum distillates.  ZEP Industrial Purple Cleaner & Degreaser – Contains between 1 and 5% Alcohols, C9- 11, ethoxylated, between 1 and 5% 2-butoxyethanol, between 1 and 5% sodium hydroxide Fatty acids, tall-oil, and sodium salts.  Spitfire RTU Power Cleaner – Contains less than 5% Benzyl alcohol, less than 3% Diethylene glycol monoethyl ether, less than 3% Sodium xylene sulfonate, between 1 and 3% Alcohol ethoxylates, between 0.1 and 1% Monoethanolamine, and between 0.1 and 1% Potassium hydroxide.  Spectracide Bug Stop “Home Barrier” – Contains less than 0.025% Gamma-cyhalothrin 2.4 Building and Atmospheric Information Survey During sampling, certain building information, including building condition (cracks in the slab, floor drains, slab thickness, etc.) and location of the HVAC system and outdoor intake, hoods, or fans were observed. According to Buncombe County Tax Department GIS, the building footprint is 21,905 square feet. The building’s ceiling height ranges from approximately 16 feet at the north and south walls to 22 feet at the apex of the roof. The building’s roof is improved by four roof vents along the centerline. Former Ticar Chemical Company—Indoor Air Monitoring Report Headwater Geology 4 The warehouse spaces are separated by a non-structural wall with access provided by two doors from the eastern and western portions. One bay door is located in the western warehouse space, and five bay doors are located in the eastern warehouse space. One of the bay doors in the eastern warehouse space is partially boarded up. The office space has an 8-foot-tall drop ceiling. A mezzanine space is located above the office and includes a conference room and storage. The office space is climate-controlled with two dedicated HVAC units. There are three HVAC units connected to the western warehouse space. Three roof-mounted heating units were observed in the eastern warehouse space. During the December 2019 sampling event, all roof vents and bay doors in the building were closed and HVAC or heating units in all spaces was operational. One of the bay doors in the eastern warehouse space was periodically opened and closed to allow delivery of materials. Approximately six to ten employees of Delong Equipment Company were working at the time of sampling. Atmospheric data for the day of sampling (December 13, 2019) was recorded  Atmospheric Pressure: 27.87” Hg  Temperature: 45F to 64F  No precipitation  A light dusting of snow was present on the ground in the morning of the sampling. Former Ticar Chemical Company—Indoor Air Monitoring Report Headwater Geology 5 3 Laboratory and Quality Administration / Quality Control Information Appropriate sample handling and chain of custody and data management procedures were employed, and the laboratory was instructed to employ QA/QC procedures to ensure appropriate sample handling and analysis and to aid in the review and validation of the analytical data. QA/QC procedures were conducted in accordance with the method protocols and included regular equipment maintenance, equipment calibrations, and adherence to specific sample custody and data management procedures. The laboratory was instructed to analyze samples in conjunction with appropriate blanks, laboratory duplicates, continuing calibration standards, surrogate standards, and matrix spiking standards in accordance with approved methodologies to monitor both instrument and analyst performance. Laboratory reporting limits for each analyte were at or below appropriate screening criteria, where possible. Additionally, the laboratory included estimated concentrations for compounds that are detected at levels above the laboratory method detection limit, but below the laboratory reporting limit (J Flags). A copy of the laboratory analytical data report and QA package consistent with Level II documentation for each group of samples submitted to and analyzed by the subcontracted laboratory is included in Appendix B. Headwater did not identify any QA/QC issues with the laboratory data. Former Ticar Chemical Company—Indoor Air Monitoring Report Headwater Geology 6 4 Results Analytical results were compared to the Department of Environmental Quality (DEQ) Division of Waste Management (DWM) Non-Residential Indoor Air Screening Level (IASL A), updated February 2018. Tabulated analytical data is included as Table 1 and the laboratory analytical report is included in Appendix B. Tetrachloroethene (PCE) was detected above the laboratory reporting limit but below the IASL (35 micrograms per cubic meter [µg/m3]) for all three indoor air samples. None of the other COCs were detected above the laboratory reporting limit. No compounds were detected in the ambient/outdoor air sample (A-4). Former Ticar Chemical Company—Indoor Air Monitoring Report Headwater Geology 7 5 Reporting and Recommendations No constituents were detected in indoor air above the IASL. These results indicate that an unacceptable risk associated with the vapor intrusion has not been identified. Based on these findings, Headwater recommends performing one additional indoor air sampling event at the same or similar three air sampling locations in December 2020 to verify stability of the indoor air conditions, in accordance with the Environmental Monitoring Work Plan (Headwater 2019).
