The Site consists of two adjacent parcels (Parcel Identification Nos. 3585994581 and 3585996351) separated by a north-south trending railroad corridor. The two Site parcels total approximately 41 acres of undeveloped land and are located in a mixed residential and commercial use area in North Belmont approximately one-mile north of Interstate 85. A Site location map is provided as Figure 1, and the Site and surrounding area are shown in Figure 2. The PD plans to redevelop the Site with one approximately 395,600 square foot (sq ft) industrial warehouse building in the western and central portions of the Site and one approximately 188,700 sq ft industrial warehouse building in the eastern portion of the Site. Redevelopment activities will also include installation of new paved access drives, parking areas, and landscaped areas. The proposed redevelopment plans are shown in Figure 3. 1.1 Background By the late 1910s, portions of the Site located west of the railroad corridor were developed with multiple single-family residences and the Acme Spinning Company cotton textile mill facility. Acme Spinning Company operated the textile mill from construction until the mid-1980s. Parkdale Mill occupied the mill facility for yarn spinning operations from the mid-1980s until approximately 2002. The mill buildings and single-family residences were razed by 2006 and 2 S:\AAA-Master Projects\Belmont Industrial\Brownfields Assessment WP\23045 Brownfields Assessment Work Plan_Acme Spinning Mill.doc the Site has remained undeveloped land since that time. The approximate footprints of the former residences and mill facility buildings are shown in Figure 2. Portion of the Site located east of the railroad corridor have historically consisted of undeveloped land. In 2015, a gravel covered equipment staging and parking area for the railroad was constructed in the in eastern portion of the Site. 1.2 Previous Assessment Activities ECS Southeast, LLP (ECS) completed Phase I Environmental Site Assessment (ESA) activities for the western portion of the Site in September 2014. The results of the Phase I ESA identified the following environmental concerns in connection with the western portion of the Site:  Historical uses in western portions of Site have included textile mill operations including Acme Spinning Mill and Parkdale Mills. ECS considered the potential for impact associated with uses of dyes and solvents as part of historical textile mill operations to represent an environmental concern for the Site and recommended additional assessment.  A release to soil was discovered at the Site in 1992 (Incident No. 16354) during closure activities associated with an approximately 10,000-gallon heating oil underground storage tank (UST). Following completion of assessment activities conducted in 2007, the North Carolina Department of Environmental Quality (DEQ) issued a No Further Action (NFA) letter dated October 30, 2007 and closed the incident. Based on the regulatory closed status of the release incident with no restrictions, ECS identified the 1992 UST incident as a Historical Recognized Environmental Condition and no further assessment was recommended. Following Phase I ESA activities, ECS completed limited soil and groundwater assessment activities at the Site in October 2014. ECS advanced four (4) soil borings (B-1 through B-4) within the footprint of former mill buildings and collected a soil sample for laboratory analysis from each boring to evaluate the potential for impacts associated with historical milling operations. In addition to the soil sampling activities, three temporary groundwater monitoring 3 S:\AAA-Master Projects\Belmont Industrial\Brownfields Assessment WP\23045 Brownfields Assessment Work Plan_Acme Spinning Mill.doc wells were installed within the borings and groundwater samples (B-1GW, B-3GW, and B-4GW) were collected for laboratory analysis to evaluate subsurface conditions. The soil and groundwater samples were submitted for analysis of volatile organic compounds (VOCs) and semi-VOCs (SVOCs). The October 2014 soil and groundwater assessment activities are documented in ECS’s Limited Soil and Groundwater Assessment report dated October 20, 2014. The locations of the ECS soil borings are shown in Figure 3, and a brief summary of the sampling results is provided below.  Laboratory analytical results for soil samples B-1 and B-3 indicated that low levels of polynuclear aromatic hydrocarbons (PAHs) including benzo(a)anthracene (up to 2.1 milligram per kilogram [mg/kg]), benzo(a)pyrene (up to 1.8 mg/kg), benzo(b)fluoranthene (up to 2.1 mg/kg) , dibenzo(a,h)anthracene (up to 0.24 J mg/kg), and indeno(1,2,3-cd)pyrene (up to 1.2 mg/kg) were detected at concentrations exceeding the DEQ Inactive Hazardous Sites Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs). No other compounds were detected at concentrations exceed the IHSB PSRGs in the soil samples.  Groundwater sample results indicated that the chlorinated solvents tetrachloroethylene (PCE; 250 microgram per liter [µg/L]) and trichloroethylene (TCE; 5.4 µg/L) were detected in groundwater sample B-4GW at concentrations exceeding the North Carolina 15A NCAC 2L Groundwater Quality Standards (2L Standards) and DEQ Division of Waste Management (DWM) Non-Residential Vapor Intrusion Groundwater Screening Levels (GWSLs). No other compounds were detected at concentrations above the 2L Standards or Non-Residential GWSLs in the groundwater samples. In December 2014, H&H conducted soil and soil vapor sampling activities at the Site to further evaluate impacts associated with historical textile milling operations. H&H collected nine (9) soil samples for laboratory analysis from seven (7) soil borings (HHSB-1 through HHSB-7) in the vicinity of former mill buildings. The soil samples were submitted for VOC and PAH analysis. In addition to soil sampling activities, H&H installed four (4) permanent soil vapor monitoring points (VMP-1 through VMP-4) and collected soil vapor samples for laboratory analysis to evaluate the potential for structural vapor intrusion into future buildings. The soil 4 S:\AAA-Master Projects\Belmont Industrial\Brownfields Assessment WP\23045 Brownfields Assessment Work Plan_Acme Spinning Mill.doc vapor samples were submitted for laboratory analysis of PCE, TCE, 1,1-dichloroethene (DCE), and vinyl chloride based on results of the previous groundwater assessment activities. The soil and soil vapor assessment activities are documented in a Phase II ESA report prepared by H&H and dated January 19, 2015. The December 2014 soil borings and permanent soil vapor monitoring points are shown in Figure 3, and a brief summary of the sampling results is provided below.  Laboratory analytical results for shallow soil samples HHSB-2 (0-2 ft), HHSB-3 (0-2 ft), and HHSB-7 (2-4 ft) indicated that low levels of PAHs including benzo(a)anthracene (up to 5.53 mg/kg), benzo(a)pyrene (up to 4.22 mg/kg), benzo(b)fluoranthene (up to 3.81 J mg/kg), benzo(k)fluoranthene (up to 4.37 mg/kg), and indeno(1,2,3-cd)pyrene (up to 2.25 J mg/kg) were detected at concentrations exceeding IHSB PSRGs. No other compounds were detected at concentrations above the IHSB PSRGs in the soil samples.  Soil vapor sampling results indicated that low levels of PCE (up to 13 micrograms per cubic meter [µg/m3]) were detected in each of the four soil vapor samples at concentrations well below the DWM Non-Residential Vapor Intrusion Sub-Slab and Exterior Soil Gas Screening Level (SGSL) of 3,500 µg/m3. In addition, trace levels of TCE (up to 0.40 J µg/m3) were detected in two of the four soil vapor samples at concentrations well below the Non-Residential SGSL of 180 µg/m3. No other compounds were detected at concentrations above the laboratory reporting limits in the soil vapor samples. To address environmental impacts identified during previous assessment activities, the PD entered the Site into the DEQ Brownfields Redevelopment Now Program and received eligibility in a letter dated August 27, 2019. Following review of available environmental assessment reports and the proposed redevelopment plans for the Site, the DEQ Brownfields Program requested that additional soil and soil vapor assessment activities be completed at the Site in an email dated October 16, 2019. This Work Plan has been prepared to address the DEQ Brownfields Program request for additional assessment. The proposed Brownfields assessment activities are outlined in the following sections. 5 S:\AAA-Master Projects\Belmont Industrial\Brownfields Assessment WP\23045 Brownfields Assessment Work Plan_Acme Spinning Mill.doc 2.0 Brownfields Assessment Activities H&H proposes to complete additional soil and soil vapor assessment activities at the Site to further evaluate the potential for impacts and to assist in management of Site media during proposed redevelopment activities. The proposed assessment activities will be performed in general accordance with the DEQ IHSB Guidelines for Assessment and Cleanup (Guidelines) dated October 2015, the DEQ DWM Vapor Intrusion Guidance (VI Guidance) dated March 2018, and most recent versions of the U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support Division (SESD) Field Branches Quality System and Technical Procedures guidance. Prior to conducting field activities, H&H will contact North Carolina 811, the public utility locator, to mark subsurface utilities located on the Site. H&H will also contract with a private utility locator to screen proposed sample locations for subgrade utilities that would not be marked by the public locator. Additionally, soil boring locations will be hand cleared to approximately 5 feet (ft) below the ground surface (bgs) prior to use of mechanical drilling equipment to further screen the boring locations for the presence of subsurface utilities. 2.1 Soil Sampling Activities H&H proposes to advance four (4) shallow soil borings in the vicinity of previous soil borings HHSB-2, HHSB-3, HHSB-4, and HHSB-7 and collect soil samples for laboratory analysis from each boring. In addition, H&H proposes to collect five (5) composite soil samples for laboratory analysis from twenty-five (25) soil borings advanced in the areas of former residences located in the northern and western portions of the Site. The proposed soil borings locations are shown in Figure 3. H&H will advance soil borings in the areas of previous soil borings HHSB-2, HHSB-3, HHSB-4, and HHSB-7 to an approximate depth of 5 feet below ground surface (ft bgs) with a decontaminated stainless-steel hand auger. Continuous soil samples will be collected from each boring from the center of the hand auger bucket. During boring advancement, soil samples will be logged for lithological description and field screened for indication of potential impacts by 6 S:\AAA-Master Projects\Belmont Industrial\Brownfields Assessment WP\23045 Brownfields Assessment Work Plan_Acme Spinning Mill.doc observation for staining, unusual odors, and the presence of organic vapors using a calibrated photoionization detector (PID). H&H will collect a soil sample from the 2 to 4 ft bgs depth interval from each soil boring. Soil samples selected for laboratory analysis will be placed directly into dedicated laboratory supplied sample containers, labeled with the sample identification, date, and requested analysis, and placed in a laboratory supplied cooler with ice. Soil samples will be submitted to a North Carolina certified laboratory under standard chain of custody protocols for analysis of Resource Conservation and Recovery Act (RCRA) metals plus hexavalent chromium by EPA Methods 6020/7471/7199. Soil samples selected for composite sampling will be collected from the 0 to 1 ft bgs depth interval. Five aliquot soil samples will be collected at each composite soil sample location to represent shallow soil conditions near former residences. The aliquot soil samples from each composite soil sample location will be combined and homogenized to form one composite soil sample for a total of five (5) composite soil samples. Composite soil samples will then be placed directly into dedicated laboratory supplied sample containers, labeled with the sample identification, date, and requested analysis, and placed in a laboratory supplied cooler with ice. Two (2) of the composite soil samples will be submitted to a North Carolina certified laboratory under standard chain of custody protocols for analysis of RCRA metals plus hexavalent chromium by EPA Methods 6020/7471/7199. The remaining three (3) composite soil samples will be analyzed for lead by EPA Method 6020. Following soil sampling activities, the soil borings will be properly abandoned and the surfaces will be repaired similar to pre-drilling conditions. Additionally, the soil sample locations will be estimated using a global positioning system (GPS) unit. 2.2 Soil Vapor Sampling Activities H&H proposes to conduct additional soil vapor assessment activities at the Site to further evaluate the potential for structural vapor intrusion into the proposed industrial buildings. H&H 7 S:\AAA-Master Projects\Belmont Industrial\Brownfields Assessment WP\23045 Brownfields Assessment Work Plan_Acme Spinning Mill.doc will collect a soil vapor sample for laboratory analysis from each of the four existing permanent soil vapor monitoring points (VMP-1 through VMP-4). In addition, H&H will advance three soil borings for installation of temporary soil vapor monitoring points in the south-central (TVMP-1) and eastern (TVMP-2 and TVMP-3) portions of the Site. The existing soil vapor monitoring points and proposed temporary soil vapor monitoring point locations are shown in Figure 3. For installation of the temporary soil vapor monitoring points, H&H will contract with a North Carolina certified drilling subcontractor to advance soil borings to approximately 10 to 15 ft bgs utilizing a track-mounted direct-push technology (DPT) drill rig. After advancing the soil borings to depth, a six-inch stainless-steel screen point fitted with ¼-inch diameter Teflon® tubing will be installed to the base of each borehole. Filter sand will be placed from the base of the boring to six inches above the screened interval. The sampling points will be completed by placing hydrated bentonite from the top of the filter sand to the ground surface. The permanent and temporary soil vapor monitoring points will each be purged by removing approximately three (3) sample train volumes of air using a syringe with a purge rate no greater than 200 milliliters per minute (mL/min). The Teflon® sample tubing will then be connected to laboratory supplied 6-Liter Summa canisters with laboratory supplied airflow regulators using a brass nut and ferrule assemblies to create an air tight seal. The airflow regulators will be calibrated by the laboratory to allow the Summa canisters to fill slowly at a rate of approximately 100 mL/min. Once the sample train is assembled, leak checks will be completed prior to collection of the soil vapor samples. The leak check will be performed by first placing a shroud over each sample point including the completed sample train, flooding the shroud with helium gas, and using a calibrated helium gas detector to measure helium concentrations within the shroud. With helium concentrations maintained at approximately 30% within the shroud, the sample tubing will be purged outside of the shroud using a syringe and a three-way valve to collect purged soil vapor into a Tedlar® bag. The purged vapor will then be analyzed using the helium gas detector to ensure that helium concentrations from the sample tubing are less than 10% of the helium concentrations measured within the shroud. 8 S:\AAA-Master Projects\Belmont Industrial\Brownfields Assessment WP\23045 Brownfields Assessment Work Plan_Acme Spinning Mill.doc Following successful leak checks, the intake valve on the sample canister will be fully opened to begin collection of the soil vapor sample. Vacuum readings on the Summa canister will be recorded prior to and following the sample period to ensure adequate sample volume was collected. A vacuum will be maintained within the canisters at the conclusion of the sampling event. After completion of sampling, the intake valve will be closed and the regulator will be disconnected from the sample canister. The starting and ending vacuum in each canister will be recorded on the chain-of-custody and submitted to the laboratory along with the samples. The Summa canisters will then be packaged and shipped to the laboratory under standard chain of custody protocols for analysis of VOCs by EPA Method TO-15. Following sampling activities, the temporary soil vapor monitoring points will be properly abandoned and the surfaces will be repaired similar to pre-drilling conditions. Additionally, the temporary soil vapor sample locations will be estimated using a GPS unit. 2.3 Quality Assurance – Quality Control Non-dedicated equipment and tools will be decontaminated prior to use at each boring or sampling location or following exposure to soil. The following samples will be collected for quality assurance/quality control (QA/QC) purposes:  One duplicate soil sample will be collected and analyzed for the same parameters as the parent sample.  One duplicate soil vapor sample will be collected using a laboratory supplied T-fitting which allows for collection of two samples from one soil vapor monitoring point simultaneously. The duplicate soil vapor sample will be analyzed for VOCs by EPA Method TO-15. Laboratory QA/QC procedures will be employed to ensure appropriate sample handling and analysis and to aid in the review and validation of the analytical data. QA/QC procedures will be conducted in accordance with the method protocols and will include regular equipment maintenance, equipment calibrations, and adherence to specific sample custody and data 9 S:\AAA-Master Projects\Belmont Industrial\Brownfields Assessment WP\23045 Brownfields Assessment Work Plan_Acme Spinning Mill.doc management procedures. Samples will be analyzed 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 will be at or below appropriate screening criteria, where possible. Additionally, H&H will request that the laboratory include estimated concentrations for compounds that are detected at levels above the laboratory method detection limit, but below the laboratory reporting limit (J flags). The laboratory analytical data report and QA package for each group of samples submitted to and analyzed by the subcontracted laboratory will be provided in an appendix to the final report. Laboratory QA data consistent with Level II documentation will be provided for this project. A copy of the completed chain-of-custody record and shipping receipt will be appended to the corresponding laboratory analytical report included with the final report. 2.4 Investigation Derived Waste Investigation derived waste (IDW) generated during the proposed assessment activities will be managed in general accordance with DEQ IHSB Guidelines. IDW generated during the assessment activities will be thin spread on-Site. However, if significant impacts are suspected (i.e., elevated PID readings, free-product, etc.) soil cuttings will be containerized in 55-gallon drums and staged on-Site pending analytical results of a composite IDW sample. Based on laboratory analytical results of IDW samples, the drums will be transported off-Site to a suitable facility for disposal. 2.5 Reporting Following completion of the assessment activities and receipt of the analytical data, H&H will document our findings in a Brownfields assessment report. The report will include a description of the sampling activities, a figure depicting sample locations, soil boring logs and temporary soil vapor monitoring point construction details, laboratory analytical data, a discussion of the data in comparison to regulatory screening levels, and conclusions and recommendations concerning our activities. DEQ risk calculators may also be used as appropriate.
