A Site location map is included as Figure 1. The Site consists of three parcels of land (Parcel Identification Numbers 07108102, 07107801, and 07107805) that total approximately 4.63 acres. The western portion of the Site is developed with an approximate 53,000-square foot (sq ft) industrial building that was constructed in 1952 and expanded in 1968. The building is utilized by Plyler Paper Stock Company to store, sort, bale, and distribute recyclable (primarily paper) products. Based on review of historical records, the existing Site building was utilized by Clorox as a bleach manufacturing facility from the early 1950s until the late 1980s, when Plyler Paper Stock Mr. Cody Cannon August 15, 2019 Page 2 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc Company began using the building for the current recycling operation. The eastern portion of the Site consists of a truck/trailer parking lot and undeveloped land. A Site map is included as Figure 2. During recent Phase I ESA activities conducted on the Site, H&H identified the following Recognized Environmental Conditions (RECs): • In March 1990, two soil borings were advanced adjacent to two petroleum aboveground storage tanks (ASTs; specific contents not reported), a former 5,000-gallon heating oil underground storage tank (UST), and a former 2,000-gallon UST (presumed to have contained heating oil) located adjacent to the northeastern corner of the Site building. Total Petroleum Hydrocarbons-Diesel Range Organics (TPH-DRO) were detected in a boring identified as Boring 1 (11 ft) at a concentration of 1,600 mg/kg, which exceeds the current North Carolina Department of Environmental Quality (DEQ) UST Section Action Level of 100 mg/kg. A separate heating oil UST release incident was identified in this area in November 1990; however, the soil data pertaining to the release did not indicate TPH-DRO in soil above the DEQ Action Level. The UST release incident received regulatory closure in July 1996. The soil impacts identified in Boring 1 (noted above) do not appear to have been included in DEQ’s evaluation of the UST release and No Further Action determination, and may be associated with the two ASTs. H&H identified the presence of TPH-DRO in soil adjacent to the northeastern portion of the Site building at a concentration above the DEQ Action Level as a REC. • H&H reviewed a Combined Preliminary Assessment/Site Inspection (September 2005) and an Expanded Site Inspection (September 2006) prepared by the DEQ Superfund Section for the former Clorox facility, which included the Site and off-Site properties located north of the Site along State Street. According to the report, the former Clorox Mr. Cody Cannon August 15, 2019 Page 3 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc facility operated in the northern portion of the Site building from the early 1950s until the late 1980s. No samples were collected on the subject Site during the Preliminary Assessment; however, several soil samples were collected on the Site during the Expanded Site Inspection. Soil analytical data indicated the presence of cadmium (3.7 mg/kg) and mercury (48.09 mg/kg) in sample CLX-009-SS (west side of the building near former rail spur) at concentrations above the Protection of Groundwater Preliminary Soil Remediation Goal (PSRG) of 3.0 mg/kg for cadmium and the Residential PSRG of 14 mg/kg for mercury. The polynuclear aromatic hydrocarbon (PAH) benzo(a)anthracene was detected near northeast exterior corner of the building in samples CLX-009-SS (0.83 mg/kg) and CLX-011-SS (1.1 mg/kg) at concentrations above the Protection of Groundwater PSRG of 0.35 mg/kg in both samples and equal to the Residential PSRG of 1.1 mg/kg in one of the samples. The PAH benzo(a)pyrene was detected in samples CLX-009-SS (0.57 mg/kg) and CLX-011-SS (0.73 mg/kg) at concentrations above the Residential PSRG of 0.11 mg/kg. H&H identified the presence of metals and PAHs at concentrations above PSRGs in soil near the northeastern corner of the building as a REC. • Based on review of Sanborn Maps and interviews with Site contacts, Clorox operated a mixing room that was used to manufacture bleach in the northwestern portion of the Site building. The Site owner reported that the room contained multiple ASTs when she purchased the Site in the late 1980s. During Site reconnaissance, H&H observed an earthen floor and a sump in the former mixing room. Previous reports indicate that the bleach manufacturing facility may have included the use of a mercury cell, which produces chlorine-free sodium hydroxide. H&H identified potential environmental impacts associated with bleach manufacturing at the Site from the early 1950s to the late 1980s as a REC. Mr. Cody Cannon August 15, 2019 Page 4 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc • In 1990, two soil borings (Boring 1 and Boring 2) were advanced adjacent to a concrete basin located adjacent to a rail spur along the western portion of the Site. Previous reports indicate that sodium hydroxide and mercury releases may have occurred from the concrete basin. Analytical data indicated the presence of mercury in a soil sample collected from Boring 1 (0.5 ft) at a concentration of 2.8 mg/kg, which exceeds the protection of groundwater PSRG of 1.0 mg/kg. The measured pH levels in samples collected from Boring 1 and Boring 2 were 13 (2.5 ft) and 13.5 (0.5 ft), respectively, which are elevated (i.e., alkaline) compared to typical soil pH levels in the area and may indicate that a release of sodium hydroxide occurred from the concrete basin. H&H identified the apparent soil impacts in the area of the former concrete basin as a REC. • Worth Chemical Corp. (818 Tuckaseegee Road) operated a chemical distribution facility located approximately 250 ft west and topographically upgradient of the subject Site. H&H reviewed a Site Assessment Work Plan prepared by Arcadis dated December 13, 2010. According to the report, the facility utilized ASTs and USTs for the storage of petroleum products, chlorinated solvents, and other hazardous materials. Results of historical soil and groundwater assessment activities conducted at the facility indicated the presence of soil and groundwater impacts associated with releases from the petroleum and chlorinated solvent storage tanks. Based on the documented solvent releases, proximity of the facility to the Site, and area topography, H&H identified the former Worth Chemical Corp. facility and associated releases as a REC for the Site. In February 2019, H&H completed Phase II ESA activities which included soil, groundwater, and exterior soil gas sampling to evaluate potential environmental risks that may affect Site redevelopment. A summary of the assessment results is provided below. Mr. Cody Cannon August 15, 2019 Page 5 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc Soil H&H collected nine soil samples for laboratory analysis to evaluate the potential for soil impacts at the Site. Samples were collected in areas of previously identified RECs and areas of potential soil disturbance as part of Site redevelopment. Laboratory analytical results did not indicate the presence of volatile organic compounds (VOCs) in soil samples at concentrations above the DEQ PSRGs. PAHs were detected at concentrations exceeding Protection of Groundwater, Residential, and/or Industrial/Commercial PSRGs in a shallow sample (0-2 ft) collected in the former bleach mixing room. The PAH benzo(a)pyrene was also detected above the Protection of Groundwater and Residential PSRG in one sample collected at 7-9 ft bgs adjacent to former heating oil USTs/ASTs. Arsenic was detected at concentrations above the Residential PSRG in the nine soil samples collected for laboratory analysis and slightly above the Industrial/Commercial PSRG in one sample. The detected concentrations of arsenic in the samples collected from the developed portion of the Site are consistent with arsenic concentrations detected in the background samples. Further, the detected concentrations are below the average published background concentration for North Carolina soils. As such, the detected arsenic concentrations appear to be naturally occurring. Hexavalent chromium was detected at estimated concentrations in samples SB-2 (0-2 ft), SB-3 (0-2 ft), SB-6 (0-2 ft), SB-9 (0-2 ft), and SB-11 (0-2 ft) above the Residential PSRG. The detected concentrations of hexavalent chromium in the samples collected from the developed portion of the Site are consistent with hexavalent chromium concentrations detected in background samples. As such, the hexavalent chromium concentrations are likely representative of background conditions. Groundwater H&H installed and sampled one temporary groundwater monitoring well (TMW-2) located downgradient of the Site building. Concentrations of benzene and vinyl chloride detected in TMW-2 exceed the North Carolina 2L Groundwater Standards (2L Standards), but are below Mr. Cody Cannon August 15, 2019 Page 6 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc Residential and Non-Residential Vapor Intrusion Groundwater Screening Levels (GWSLs). No SVOCs were detected in sample TMW-2 above the laboratory method detection limits, and no metals were detected in sample TMW-2 at concentrations above the 2L Standards. Exterior Soil Gas H&H collected two soil gas samples (SG-1 and SG-2) near the western exterior wall of the former Clorox facility. VOCs were detected in the exterior soil gas samples at concentrations below the Residential and Non-Residential SGSLs. The Site received a letter of eligibility for entry into the DEQ Brownfields Program (Brownfields Project No. 22039-18-060) on March 26, 2019. The Prospective Developer (PD) plans to perform extensive interior and exterior renovations of the existing structure for use as an office building. The eastern portion of the Site will be graded and developed into a parking lot. On July 8, 2019, a kick-off/data gap meeting was held at the Site with the PD, DEQ Brownfields Program personnel, Parker Poe (PD’s legal counsel), and H&H to discuss Site history, previous environmental assessment activities, proposed redevelopment plans, data gaps, and the proposed schedule for completing the Brownfields Agreement. This work plan describes proposed assessment activities to address data gaps identified during the kick-off meeting. The proposed receptor survey and groundwater and vapor intrusion assessment activities are summarized in the following sections. 2.0 Brownfields Assessment Activities The proposed assessment activities will be performed in general accordance with DEQ’s Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup dated October 2015, DEQ’s Division of Waste Management (DWM) Vapor Intrusion Guidance dated March 2018, and most recent versions of the U.S. Environmental Protection Agency Region IV Science and Ecosystem Support Field Branches Quality System and Technical Procedures guidance. Mr. Cody Cannon August 15, 2019 Page 7 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc Prior to conducting field activities, H&H will contact North Carolina 811, the public utility locator, to mark subsurface utilities at the Site. H&H will also contract a private utility locator to mark utilities which may not be identified by the public locator. Additionally, each boring location will be cleared with a decontaminated stainless-steel hand auger to a depth of approximately 5 feet (ft) below ground surface (bgs) to further screen the boring locations for the presence of subsurface utilities. In accordance with Mecklenburg County regulations, H&H will also obtain a Subsurface Investigation Permit (SIP) from the Mecklenburg County Land Use and Environmental Services Agency (LUESA) prior to temporary monitoring well installation and sampling. After completion of the activities, H&H will upload temporary monitoring well records prepared by a North Carolina licensed driller in order for LUESA to close the SIP. 2.1 Receptor Survey H&H will perform a Brownfields receptor survey in accordance with DEQ Brownfields Section guidance. The receptor survey will include information about land use and zoning in the Site area. In addition, H&H will conduct a field search for water supply wells, basements, utility manways and chases, storm sewers, other underground utilities, drains, and surface water within a 1,500 ft radius of the Site. In addition, H&H will review the Mecklenburg County Well Information System to identify registered water supply wells in the area and, if warranted, contact the utility companies for information concerning underground utilities in the immediate area of the Site. The receptor survey will be completed using the most current version of the Brownfields Property Receptor Survey form. 2.2 Groundwater Assessment Activities H&H will direct the drilling contractor to install temporary groundwater monitoring wells (TMWs) at two locations at the Site to evaluate groundwater conditions. Temporary monitoring wells BF-TMW-1 and BF-TMW-2 will be installed in the western (upgradient) portion of the Mr. Cody Cannon August 15, 2019 Page 8 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc Site in the locations of previous exterior soil gas samples SG-1 and SG-2, respectively. The locations of the TMWs are shown on Figure 2. The TMW borings will be advanced with a track-mounted drill rig capable of utilizing hollow- stem auger drilling techniques. During drilling, soil cuttings will be collected and logged for lithologic description and field screened for the presence of staining and elevated organic vapors using a calibrated PID. The temporary monitoring wells will be constructed of 2-inch diameter PVC with 15 ft well pre-packed well screen set to bracket the water table and 2-inch diameter PVC well casing to the ground surface. Additional filter sand will be placed from the bottom of the borings to approximately 2 ft above the top of the well screens. The temporary wells will be completed by placing a hydrated bentonite seal from the top of the sand filter pack to the ground surface. Once the temporary monitoring wells are installed, the wells will be allowed to equilibrate to static conditions and a decontaminated electronic water level indicator will be used to measure the depth to the water table relative to the ground surface in each well. The wells will then be developed until field parameters have stabilized (pH ± 0.1 SU and conductivity varies no more than 5%) and turbidity is less than 10 NTUs. After development, a groundwater sample will be collected utilizing low flow/low stress purging techniques using a peristaltic pump and dedicated polyethylene tubing. The intake point of the pump tubing will be placed in the approximate mid-portion of the screened interval of the well and groundwater will be removed at a rate no greater than 200 milliliters per minute. H&H will utilize water quality meters to collect measurements of pH, temperature, dissolved oxygen, oxidation reduction potential, turbidity, and specific conductivity at 3- to 5-minute intervals during the purging process. Purging will be considered complete when the parameters stabilize (pH ± 0.1 SU, conductivity varies no more than 5%, and turbidity is less than 10 NTUs). Once groundwater parameters stabilize, the groundwater samples for VOC analysis will be collected directly into laboratory supplied sample containers using the “soda straw” method to Mr. Cody Cannon August 15, 2019 Page 9 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc minimize volatile loss through the peristaltic pump head. Samples collected for the remaining analyses will be collected directly into laboratory supplied sample containers from the dedicated sample tubing through the peristaltic pump head. The sample containers will be labeled with the sample identification, date, and requested analysis, and placed in an iced laboratory supplied cooler. The sample will be delivered to a North Carolina certified laboratory under standard chain of custody protocols for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and Resource Conservation and Recovery Act (RCRA) metals by EPA Method 6020/7470. The groundwater sample locations will be estimated using a hand-held GPS unit. Following sampling and surveying activities, the temporary monitoring wells will be properly abandoned by a licensed well driller and the surfaces will be restored to approximately match pre-drilling conditions. 2.3 Sub-Slab Vapor Assessment Activities H&H proposes to collect four sub-slab vapor samples (SSV-1 through SSV-4) inside the current building to evaluate potential vapor intrusion risk. The proposed sub-slab vapor sample locations are shown on Figure 2. H&H will drill through the concrete floor at four permanent sub-slab vapor monitoring points using a rotary hammer drill and 1½-inch diameter drill bit to advance a pilot hole into the concrete slab to a depth of approximately 1¾ inches below the surface. A drill guide will then be placed in the pilot hole, and a 5/8-inch diameter drill bit will be utilized to advance the boring through the concrete slab. Following concrete borehole advancement, loose concrete cuttings will be removed from the borings, and a Cox-Colvin Vapor Pin™ (vapor pin) assembly (brass sampling point and silicone sleeve) will be seated in the borehole using an installation/extraction tool and hammer. The vapor pin will be installed as a flush-mount sample point capable of being secured with a stainless-steel cover that screws onto the sampling point and is seated within the pilot hole annulus. Mr. Cody Cannon August 15, 2019 Page 10 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc Following installation and prior to collection of the sub-slab vapor samples, a leak check will be conducted by constructing a shroud around each sampling point and flooding the air within the shroud with helium gas. Helium concentrations inside the shroud will be measured using a helium gas detector. Using a syringe and three-way valve, the Teflon tubing and surrounding sand pack will be purged of approximately three volumes. Following purging, a sample will be collected from the sample tubing outside the shroud and analyzed using the helium gas detector to ensure that helium concentrations are less than 10% of the helium concentrations in the shroud. Following a successful leak check, a laboratory-supplied 6-liter stainless steel Summa sample canister will be connected to an in-line flow controller with a vacuum gauge. The flow controller will be connected to the sample tubing using a brass nut and ferrule assembly to form an air-tight seal. The flow regulator will be pre-set by the laboratory to regulate the vapor intake rate to 6-liters per hour. Once the sample train is assembled, the intake valve on the canister will be fully opened to begin collection of the sub-slab vapor sample. Vacuum readings on the Summa canister will be recorded prior to and following the one-hour sampling period to ensure adequate sample volume was collected. A vacuum will be maintained within the canisters at the conclusion of the sampling event. After sample collection, the Summa canister’s valve will be closed, and the regulator will be disconnected from the canister. The canisters will be placed in laboratory supplied shipping containers, properly labeled and shipped under standard chain-of-custody protocols to a qualified laboratory for analysis of VOCs by EPA Method TO-15. The laboratory will be requested to use reporting limits that are below DEQ DWM Non-Residential SGSLs. Following the collection of the sub-slab vapor samples, a stainless-steel cover with be screwed onto the sampling point to protect the sampling point and to allow future access if future sub-slab vapor testing is warranted based on the analytical results. Each sample location will be estimated by measuring from known benchmarks (e.g. doorways, walls, etc.). Mr. Cody Cannon August 15, 2019 Page 11 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc 2.4 Quality Assurance/Quality Control Samples The following samples will be collected for quality assurance/quality control (QA/QC) purposes: • One duplicate groundwater sample will be collected and analyzed for the same parameters as the parent sample (i.e., VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and RCRA metals by EPA Method 6020/7470). • One trip blank will accompany the groundwater samples submitted for VOC analysis during sampling and shipment. The trip blank will be analyzed for VOCs by EPA Method 8260. • H&H will collect one duplicate sub-slab vapor sample using a “T” sample connection which will allow for the collection of two soil vapor samples from the same location simultaneously. The duplicate sub-slab vapor sample will be analyzed for VOCs by EPA Method TO-15. Non-dedicated equipment and tools will be decontaminated prior to use at each boring or sampling location, or following exposure to soil or groundwater. 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 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). Mr. Cody Cannon August 15, 2019 Page 12 S:\AAA-Master Projects\Beacon Partners- BEP or BCP\BCP-129 Gesco Street\Brownfields Assessment\Work Plan\Brownfields Assessment Work Plan - Former Clorox Facility (NCBP No. 23009-19-060).doc A copy of 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 requested 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. 2.5 Investigation Derived Waste Investigation derived waste (IDW) generated during the assessment activities will be thin spread on-Site. However, if significant impacts are suspected, the soil cuttings and/or purge water 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. 2.6 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 and well construction logs, a discussion of the data in comparison to regulatory screening levels, laboratory analytical data, and conclusions and recommendations concerning our activities.
