January 2019 1 1.0 INTRODUCTION The May 31, 2018 Targeted Sampling Work Plan (Work Plan) was developed as a guidance document in support of investigative sampling activities at the Badin Business Park LLC facility (facility), formerly known as the Alcoa Badin Works facility. The Work Plan followed the January 31, 2018 North Carolina Department of Environmental Quality (NCDEQ) request for soil sampling at the former facility and subsequent meetings on May 10 and 24, 2018. The approach for the sampling activities was developed based on information obtained from reconnaissance, previous investigations, and historical remedial activities conducted at the facility. NCDEQ granted approval of the Work Plan on June 15, 2018. 1.1 Overview The former Alcoa-Badin Works facility was a primary aluminum smelting plant. Aluminum production began at the facility in 1916 after purchasing and completing the holdings of a French combine, which had begun work on a smelter. The former Alcoa-Badin Works facility consisted of potlines; electrode plants where anodes and cathodes were manufactured; casting facilities; a machine shop; and various offices and utility buildings. Aluminum production was curtailed in August 2002. The plant continued to manufacture anodes and high-purity aluminum until 2007. The plant was permanently closed in 2010. Demolition related activities (i.e., removal of selected equipment, buildings and foundations) were completed in 2012. Since closing the plant, the facility has been redeveloped into a business park for manufacturing companies. 1.2 Basis of Work Environmental investigations have been performed at the facility in the past; however, these investigations targeted specific areas of the facility where constituents of interest (COIs) were known or suspected to have been utilized. Other areas of the facility were not historically evaluated because environmental impacts were not believed to be present or the areas were otherwise covered by plant buildings or obstructions. The basis for the work was to supplement previous investigations by obtaining information to assess for the presence of COIs in soils on the facility. To accomplish this, soil samples were collected and analyzed to evaluate soil quality. Results from the investigation are detailed below. ENVIRONEERING, INC. 137-263 Targeted Sampling Report – Badin Business Park Facility - Badin, NC; January 2019 2 2.0 SAMPLE COLLECTION Implementation of the soil sampling program was conducted September 24 through 26, 2018. Sample collection, shipment, and decontamination were conducted following procedures outlined in the Work Plan. Field work included collection of sixty-five (65) soil samples across eight (8) facility locations. Soil sample locations are presented on Figure 2-1. At each location, a soil core was collected from soil borings using direct-push technology (e.g., Geoprobe). As previously stated in the Work Plan, demolition related activities (removal of selected equipment, buildings and foundations) were completed in 2012. Selected building foundations remain in place and a substantial portion of the facility was backfilled with crushed concrete and soil backfill. If demolition-related materials (e.g. crushed concrete and backfill) or a concrete pad were not present at the surface, a soil sample was collected between the interval of 0 to 1 foot below ground surface (bgs). If demolition materials or a concrete pad were encountered, the shallow soil sample interval of 0 to 1 foot was collected immediately below the demolition materials or concrete pad and the sampling proceeded according to the deeper soil sample collection procedures. Deeper soil samples were targeted for collection between the interval of 4 to 5 feet below the collection of the shallow soil sample. Where remnant building foundations were encountered, an attempt was made to core through the foundation and collect a sample beneath the foundation. If the foundation could not be cored through, the boring was relocated to a location outside the understood footprint of the former building foundation. ENVIRONEERING, INC. 137-263 Targeted Sampling Report – Badin Business Park Facility - Badin, NC; January 2019 3 3.0 SAMPLING RESULTS Samples were provided to Pace Analytical Services, LCC of Huntersville, North Carolina for analysis in accordance with the Work Plan. Laboratory reports and completed chain of custody forms are provided in Appendix A. Laboratory analytical results were compared to the February 2018 published NCDEQ Preliminary Soil Remediation Goals, more specifically the Protection of Groundwater and the Industrial/Commercial Health-based (Industrial) Preliminary Soil Remediation Goals (PSRGs). A summary of sampling results from targeted areas follows. 3.1 Former Electrical Shop and Warehouse The former Electrical Shop and Warehouse buildings (Buildings 007 and 007A) were located in the central portion of the facility inside the eastern fenceline. Prior to demolition, a portion of Building 007A served as a central accumulation area for waste. A review of historical data indicated that this area had continually served as an electrical shop and warehouse. Potential COIs resulting from operations include volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs), and additional constituents associated with waste management from primary reduction operations (fluoride, cyanide, and polycyclic aromatic hydrocarbons (PAHs)). Two soil samples and one duplicate soil sample were collected from one soil boring (ESW-SB001) from within the former Electrical Shop and Warehouse Area. Soil sample analytical results are summarized in Table 2-1. 3.1.1 Volatile Organic Compounds Volatile organic compounds were not detected in the samples at concentrations above NCDEQ Protection of Groundwater PSRGs or Industrial PSRGs. 3.1.2 Polychlorinated Biphenyls PCB Aroclors were not detected in the samples at concentrations above laboratory detection limits. 3.1.3 Fluoride and Cyanide Fluoride and cyanide were not detected in the samples at concentrations above the PSRGs. 3.1.4 Polycyclic Aromatic Hydrocarbons Benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, dibenz(a,h)anthracene, and 1-methylnaphthalene were detected in the shallow soil sample (ESW-SB001 (0’-1’)) at concentrations above Protection of Groundwater PSRGs; however, concentrations were below Industrial PSRGs. PAHs were not detected in the deep soil sample (ESW-SB001 (4’-5’)) at concentrations above the PSRGs. Dibenz(a,h)anthracene was detected in the duplicate shallow soil sample (ESW-SB001 (0’-1’) DUP) at a concentration below the Protection of Groundwater PSRG. ENVIRONEERING, INC. 137-263 Targeted Sampling Report – Badin Business Park Facility - Badin, NC; January 2019 4 3.2 Former Maintenance Shop Area The former Maintenance Shops (Buildings 010 and 012) were located in the central portion of the facility and comprised several buildings which are believed to have contained specialized maintenance activities. Activities in this area potentially utilized various oils, greases, and solvents during routine operations. A review of historical data indicated that this area had continually served as a maintenance shop and warehouse. Potential COIs resulting from operations include VOCs and PAHs. Eight soil samples were collected from four soil borings (MSA-SB001 through MSA-SB004) from within the former Maintenance Shop Area. Soil sample analytical results are summarized in Table 2-2. 3.2.1 Volatile Organic Compounds Volatile organic compounds were not detected in the samples at concentrations above the PSRGs. 3.2.2 Polycyclic Aromatic Hydrocarbons Benzo(a)anthracene, benzo(a)pyrene, and 1-methylnaphthalene were detected in one shallow soil sample (MSA-SB001 (0’-1’)) at concentrations above Protection of Groundwater PSRGs; however, concentrations were below Industrial PSRGs. PAHs were not detected in the deep soil sample (MSA-SB001 (4’-5’)) at concentrations above the PSRGs. Benzo(a)pyrene was detected in two shallow soil samples (MSA-SB002 (0’-1’) and MSA-SB004 (0’-1’)) at concentrations above the Protection of Groundwater PSRG; however, the concentrations were below the Industrial PSRG. PAHs were not detected in the deep soil sample (MSA-SB002 (4’-5’) and MSA-SB004 (4’-5’)) at concentrations above the PSRGs. Benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, dibenz(a,h)anthracene, 1-methylnaphthalene, and naphthalene were detected in one shallow soil sample (MSA-SB003 (0’-1’)) at concentrations above Protection of Groundwater PSRGs. Benzo(a)pyrene was the only constituent detected at a concentration above the Industrial PSRGs. PAHs were not detected in the deep soil sample (MSA-SB003 (4’-5’)) at concentrations above the PSRGs. 3.3 Former Cathode Plant Area The former Cathode Plant Area (Buildings 014 and 139) was located on the eastern edge of the facility. Carbon cathodes were formed with anthracite coal, graphite, and coal tar pitch, and rodded with collector bars. A review of historical data indicated that this area had continually served as a cathode plant. Potential COIs in the former Cathode Plant Area include PCBs and PAHs. Four soil samples were collected from two soil borings (CAT-SB001 and CAT-SB002) from within the former Cathode Plant Area. Soil sample analytical results are summarized in Table 2-3. ENVIRONEERING, INC. 137-263 Targeted Sampling Report – Badin Business Park Facility - Badin, NC; January 2019 5 3.3.1 Polychlorinated Biphenyls PCB Aroclors were not detected in the samples at concentrations above laboratory detection limits. 3.3.2 Polycyclic Aromatic Hydrocarbons Benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, and dibenz(a,h)anthracene were detected in one shallow soil sample (CAT-SB001 (0’-1’)) at concentrations above Protection of Groundwater PSRGs. Benzo(a)pyrene was the only constituent detected at a concentration above the Industrial PSRGs. Benzo(a)pyrene was detected in the deep soil sample (CAT-SB001 (0’-1’)) at a concentration above the Protection of Groundwater PSRG; however, the concentration was below the Industrial PSRG. PAHs were not detected in the remaining samples at concentrations above the PSRGs. 3.4 Former Anode Plant Area The former Anode Plant Area (Buildings 050B and 050C) was located in the northern portion of the facility. In the former Anode Plant, calcined petroleum coke was ground, segregated by size, blended, oven dried, and combined with carbon pitch to create a paste which was then formed into a green anode block via a hydraulic press. A review of historical data indicated that this area has continually served as an anode plant. Potential COIs in the former Anode Plant Area include PCBs and PAHs. Four soil samples were collected from two soil borings (ANO-SB001 and ANO-SB002) from within the former Anode Plant Area. Soil sample analytical results are summarized in Table 2-4. 3.4.1 Polychlorinated Biphenyls Aroclor 1232 was detected in one shallow soil sample (ANO-SB002 (0’-1’)) at a concentration above the Protection of Groundwater PSRG; however, the concentration was below the Industrial PSRG. PCB Aroclors were not detected in the deep soil sample (ANO-SB002 (4’-5’)) at concentrations above the PSRGs. PCB Aroclors were not detected in the remaining samples at concentrations above the PSRGs. 3.4.2 Polycyclic Aromatic Hydrocarbons Benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, and dibenz(a,h)anthracene were detected in one shallow soil sample (ANO-SB001 (0’-1’)) at concentrations above Protection of Groundwater PSRGs; however, the concentrations were below the Industrial PSRGs. PAHs were not detected in the deep soil sample (ANO-SB001 (4’-5’)) at concentrations above the PSRGs. Benzo(a)anthracene, benzo(a)pyrene, and benzo(b)fluoranthene were detected in one shallow soil sample (ANO-SB002 (0’-1’)) at concentrations above Protection of Groundwater PSRGs. Benzo(a)pyrene was the only constituent detected at a concentration above the Industrial PSRGs. PAHs were not detected in the deep soil sample (ANO-SB002 (4’-5’)) at concentrations above the PSRGs. ENVIRONEERING, INC. 137-263 Targeted Sampling Report – Badin Business Park Facility - Badin, NC; January 2019 6 3.5 Former Potline and Bath Crushing Area The Potlines (Buildings 201 through 204) were the main aluminum production areas in the central and southern portions of the facility. The former Bath Crushing Area (Building 204H) was located immediately west of the potlines. The potlines were each comprised of multiple rectangular “pots” where aluminum was generated through electrolysis of a molten cryolite and alumina solution. Carbon was used for the cathodes and anodes, which were consumed in the process. A review of historical data indicated that this area may also have been historically utilized for potlines. Potential COIs in these areas are constituents associated with primary reduction operations (fluoride, cyanide, and PAHs). Thirty-four (34) soil samples were collected from seventeen (17) soil borings (PBC-SB001 through PBC-SB017) from within the former Potline and Bath Crushing Area. Soil sample analytical results are summarized in Table 2-5. 3.5.1 Fluoride and Cyanide Fluoride and cyanide were not detected in the samples at concentrations above the PSRGs. 3.5.2 Polycyclic Aromatic Hydrocarbons Benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, and 1-methylnaphthalene were detected in one shallow soil sample (PBC-SB004 (0’-1’)) at concentrations above Protection of Groundwater PSRGs; however, the concentrations were below Industrial PSRGs. PAHs were not detected in the deep soil sample (PBC-SB004 (4’-5’)) at concentrations above laboratory detection limits. Benzo(a)anthracene and benzo(a)pyrene were detected in one shallow soil sample (PBC-SB008 (0’-1’)) at concentrations above Protection of Groundwater PSRGs; however, concentrations were below Industrial PSRGs. PAHs were not detected in the deep soil sample (PBC-SB008 (4’-5’)) at concentrations above laboratory detection limits. PAHs were not detected in the remaining samples at concentrations above the PSRGs. 3.6 Former Anode Butt Reclamation and Rod Shop The former Anode Butt Reclamation and Rod Shop (Building 232) was located in the central portion of the facility. After the anodes were consumed as part of the reduction process, the rod and cast iron were removed for reuse and recycling from the remnants of the anode, or anode butt. The anode butts were transported back to the Anode Plant for forming into new anodes. After baking at the former Carbon Baking Furnace, the anode was coupled to the anode rod with cast iron prior to storage or transport to the potline. Potential COIs in this area include PAHs. Four soil samples were collected from two soil borings (ABR-SB001 and ABR-SB002) from within the former Anode Butt Reclamation and Rod Shop area. Soil sample analytical results are summarized in Table 2-6. ENVIRONEERING, INC. 137-263 Targeted Sampling Report – Badin Business Park Facility - Badin, NC; January 2019 7 3.6.1 Polycyclic Aromatic Hydrocarbons Benzo(a)pyrene was detected in one shallow soil sample (ABR-SB001 (0’-1’)) at a concentration above the Protection of Groundwater PSRG; however, the concentration was below the Industrial PSRG. PAHs were not detected in the deep soil sample (ABR-SB001 (4’-5’)) at concentrations above the PSRGs. Benzo(a)anthracene, benzo(a)pyrene, and benzo(b)fluoranthene were detected in one shallow soil sample (ABR-SB002 (0’-1’)) at concentrations above Protection of Groundwater PSRGs; however, concentrations were below Industrial PSRGs. Benzo(a)pyrene was detected in the deep soil sample (ABR-SB002 (4’-5’)) at a concentration above the Protection of Groundwater PSRG; however, the concentration was below the Industrial PSRG. No additional PAHs were detected in the deep soil sample at concentrations above the PSRGs. 3.7 Former Carbon Baking Furnace The former Carbon Baking Furnace (Buildings 261 and 262) was located in the central portion of the facility. Green anodes manufactured in the former Anode Plant were either stored or transported to the baking furnace where they were baked to drive off pitch volatiles. A review of historical data indicated that this area previously contained a baking furnace. Potential COIs in this area include PAHs. Four soil samples were collected from two soil borings (CBF-SB001 and CBF-SB002) from within the former Carbon Baking Furnace area. Soil sample analytical results are summarized in Table 2-7. 3.7.1 Polycyclic Aromatic Hydrocarbons Benzo(a)anthracene and benzo(a)pyrene were detected in one shallow soil sample (CBF-SB001 (0’-1’)) at concentrations above Protection of Groundwater PSRGs; however, concentrations were below Industrial PSRGs. PAHs were not detected in the deep soil sample (CBF-SB001 (4’-5’)) at concentrations above the PSRGs. Benzo(a)pyrene was detected in one shallow soil sample (CBF-SB002 (0’-1’)) at a concentration above the Protection of Groundwater PSRG; however, the concentration was below the Industrial PSRG. PAHs were not detected in the deep soil sample (CBF-SB002 (4’-5’)) at concentrations above the PSRGs. 3.8 Former Rectifier Station The former Rectifier Station (Buildings 301 and 302) was located on the northern edge of the former potlines (Buildings 201 through 204) and near the former potlines associated with the early 20th century plant. A review of historical data indicated that this area may have been historically utilized for potlines. Potential COIs in this area include PCBs and constituents associated with primary reduction operations (fluoride, cyanide, and PAHs). Four soil samples were collected from two soil borings (REC-SB001 and REC-SB002) from within the former Rectifier Station area. Soil sample analytical results are summarized in Table 2-8. ENVIRONEERING, INC. 137-263 Targeted Sampling Report – Badin Business Park Facility - Badin, NC; January 2019 8 3.8.1 Polychlorinated Biphenyls PCB Aroclors were not detected in the samples at concentrations above laboratory detection limits. 3.8.2 Fluoride and Cyanide Fluoride and cyanide were not detected in the samples at concentrations above the PSRGs. 3.8.3 Polycyclic Aromatic Hydrocarbons Benzo(a)anthracene, benzo(a)pyrene, and benzo(b)fluoranthene were detected in one shallow soil sample (REC-SB001 (0’-1’)) at concentrations above Protection of Groundwater PSRGs; however, concentrations were below Industrial PSRGs. PAHs were not detected in the deep soil sample (REC-SB001 (4’-5’)) at concentrations above the PSRGs. PAHs were not detected in the remaining samples at concentrations above the PSRGs. 3.9 Field Blanks One equipment blank was analyzed as part of this project. The equipment blank was prepared by running analyte free distilled water across sample collection equipment (sampling core barrel) after decontamination and placing it in the appropriate sample containers for analysis. No constituents were detected at concentrations above laboratory detection limits. Results are summarized in Table 2-9. One trip blank was analyzed as part of this project. The trip blank was prepared by the laboratory and placed in the cooler containing samples selected for VOC analysis. No constituents were detected at concentrations above laboratory detection limits.

To accomplish this, sixty-five (65) soil samples were collected across eight (8) facility locations and submitted for analytical analysis in accordance with the May 31, 2018 Targeted Sampling Work Plan. Results from the investigation are summarized below.  Fluoride, cyanide, and VOCs were not detected at concentrations above Protection of Groundwater PSRGs or Industrial PSRGs.  A single Aroclor, Aroclor 1232, was detected in one shallow soil sample at a concentration above the Protection of Groundwater 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; therefore, exposure via the soil-to- groundwater leaching pathway is not believed to be present. Further, Aroclor 1232 is not common to past operations and as a result the detection of Aroclor 1232 is believed to be anomalous.  Concentrations of PAHs were detected in shallow soil samples above the Protection of Groundwater PSRG in fifteen (15) soil samples; however, detection of PAHs in the deep soil samples at a concentration above the Protection of Groundwater PSRG was limited to a single constituent in a single instance (i.e., benzo(a)pyrene at ABR-SB002 (4’-5’)). Because PAHs have not been historically detected in groundwater samples, exposure via the soil-to-groundwater leaching pathway is not believed to be present.  Three shallow soil samples in three separate targeted areas each contained a concentration of a single PAH (i.e., benzo(a)pyrene) slightly exceeding the Industrial PSRG. PAHs were not detected at concentrations exceeding the Industrial PSRGs in the deeper soil samples. Exposure to the soils exceeding the Industrial PSRG is limited as all three sample locations are currently covered by crushed concrete fill or gravel. ENVIRONEERING, INC.
