A Site location map is provided as Figure 1. The Site consists of an approximate 2.4-acre parcel of land (Parcel Identification Number 12103209) that is developed with an approximate 65,136-square foot (sq ft) industrial warehouse building that is currently vacant. The central and eastern portions of the building were constructed in 1958, and the western portion of the building was constructed in the late 1970s. A Site map is included as Figure 2. The subject Site was historically occupied by portions of a Cotton Seed Oil Mill (late 1800s to early 1900s), portions of the Virginia Carolina Chemical (VCC) fertilizer company (early 1900s to mid- 1900s), a lumber milling operation in the 1960s, and a steel pail painting operation in the 1980s. The Site was then occupied by the Charlotte Salvage Company from the 1980s to the late 2010s. H&H performed Phase II Environmental Site Assessment (ESA) activities at the Site in August 2019 to evaluate potential areas of environmental concern associated with historical activities conducted at the Site and on nearby upgradient properties. The results of the Phase II ESA indicated the presence of arsenic in Site soils at concentrations exceeding North Carolina Department of Environmental Quality (NC DEQ) Protection of Groundwater (PoG), Residential, and Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs). Additionally, potentially elevated levels of chromium and hexavalent chromium were detected in soil samples. 2 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc Groundwater analytical results did not indicate the presence of VOCs, SVOCs, or metals at concentrations exceeding regulatory standards. Additionally, sub-slab vapor and soil gas analytical results did not indicate the presence of VOCs at concentrations exceeding regulatory screening levels. The PD will perform interior and exterior renovations of the existing Site structure for commercial use. Future redevelopment at the Site may include demolition of the current Site structure for construction of a multi-story structure. The Site received a letter of eligibility for entry into the DEQ Brownfields Program (Brownfields Project No. 23053-19-060) on October 8, 2019. On October 23, 2019, a kick-off/data gap meeting was held at the Site with the PD, DEQ Brownfields Program personnel, and H&H to discuss Site history, previous environmental assessment activities at the Site, proposed redevelopment plans, data gaps, and the proposed schedule for completing the Brownfields Agreement. DEQ followed-up in an email dated November 5, 2019 requesting that five sub-slab vapor samples be collected to further assess potential risks for future use of the Site building. H&H previously sampled sub-slab vapor and soil gas concentrations during warm weather in August 2019. Results did not indicate a vapor intrusion condition above NC DEQ Residential or Non-Residential Soil Gas Screening Levels (SGSLs) or DEQ risk-based target levels. H&H also conducted a sensitive receptor survey in the vicinity of the Site. Information regarding the recent assessment activities is provided in the following sections. 3 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc 2.0 Brownfields Assessment Activities In accordance with the DEQ Brownfields Program approved Proposed Scope of Work dated November 14, 2019, H&H conducted further assessment activities at the Site in December 2019. The assessment included the collection of sub-slab vapor samples and a receptor survey to further evaluate Site impacts and their potential associated risks for redevelopment and future Site use. The assessment activities were conducted in general accordance with the DEQ 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, the most recent versions of the U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support (SESD) Field Branches Quality System and Technical Procedures guidance, and the DEQ approved Proposed Scope of Work. The results of the sub-slab vapor assessment activities are provided in Section 3.0 and the receptor survey results are provided in Section 4.0. Conclusions and recommendations based on the results of the assessment activities are provided in Section 5.0. 4 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc 3.0 Sub-Slab Vapor Assessment Activities On December 3, 2019, H&H installed and sampled five sub-slab vapor monitoring points (SSV-1 through SSV-5) within the Site building. Temperatures during the sampling event were between 37 and 46 degrees Fahrenheit. SSV-1 through SSV-3 were installed near the three prior vapor sample locations. SSV-4 and SSV-5 were installed in the northern and southern portions of the eastern warehouse building, respectively. Sub-slab vapor sample locations are shown on Figure 2. 3.1 Sub-Slab Vapor Sampling Methodology H&H drilled through the concrete floor at the five sub-slab vapor monitoring point locations 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 was then placed in the pilot hole, and a 5/8-inch diameter drill bit was utilized to advance the boring through the concrete slab. Following concrete borehole advancement, loose concrete cuttings were removed from the borings, and a Cox-Colvin Vapor Pin™ (vapor pin) assembly (brass sampling point and silicone sleeve) was seated in the borehole using an installation/extraction tool and hammer to form an air-tight seal. After installation and prior to collection of the sub-slab samples, a leak check was conducted by constructing a shroud around each sub-slab vapor sampling point and Summa sample canister flooding the air within the shroud with helium gas. Helium concentrations inside the shroud were measured using a helium gas detector. Using a syringe and three-way valve, the vapor point, Teflon tubing, and surrounding sand pack was purged of approximately three volumes of air. Following purging, a sample was collected from the sample tubing outside the shroud and analyzed using the helium gas detector to ensure that helium concentrations were less than 10% of the helium concentrations in the shroud. Following a successful leak check, a laboratory-supplied 1-liter stainless steel Summa sample canister was connected to an in-line flow controller with attached vacuum gauge. The flow controller was then connected to the sample tubing using a brass nut and ferrule assembly to form an air-tight seal. The flow regulator was pre-set by the laboratory to regulate the vapor intake rate to 5 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc approximately 100 milliliters per minute. Once the sample train was assembled, the intake valve on the canister was fully opened to begin collection of the sub-slab vapor sample. Vacuum readings on the Summa canister were recorded prior to and following the sampling period to ensure adequate sample volume was collected. As a quality control measure, negative pressure was maintained within the canisters at the conclusion of the sampling event. After sample collection, the Summa canister’s valves were closed prior to the regulator being disconnected from the canister. The Summa canisters were then placed in laboratory supplied shipping containers, properly labeled, and shipped under standard chain-of-custody protocols to Pace Analytical Laboratory (Pace) for analysis of VOCs by EPA Method TO-15. For quality assurance/quality control purposes, one duplicate sub-slab vapor sample was collected from SSV-4 using a “T”-fitting for simultaneous sample collection into two Summa canisters. The duplicate sample was also analyzed for VOCs by EPA Method TO-15. Upon completion of sampling activities, the vapor pins were removed and the concrete surface was patched with concrete to match the surrounding area. Each sample location was estimated by measuring from known benchmarks (doorways, walls, etc.). 3.2 Sub-Slab Vapor Analytical Results The vapor samples were collected during cold weather conditions in December 2019. The sub-slab vapor analytical results are summarized in Table 1. The laboratory analytical report and chain of custody record are provided in Appendix B. Sub-slab vapor analytical results were compared to the February 2018 DEQ DWM Residential and Non-Residential SGSLs. Laboratory analytical results indicated the presence of low levels of several VOCs at concentrations above laboratory method detection limits in the sub-slab vapor samples. However, no compounds were detected in the sub-slab vapor samples at concentrations exceeding the Residential or Non- Residential SGSLs. Trichloroethene (TCE), a common vapor intrusion compound of concern, was not detected during the December 2019 sampling event. 6 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc The DEQ DWM SGSLs are conservative and based upon a lifetime incremental cancer risk (LICR) of 1 x 10-5 for potential carcinogenic effects and a hazard quotient (HQ) of 0.2 for potential non-carcinogenic effects. The DEQ acceptable cumulative LICR for potential carcinogenic risks is 1 x 10-4, and the acceptable cumulative risk level for non-carcinogenic risks is a hazard index (HI) less than 1. To further evaluate potential risks for structural vapor intrusion into the Site building, H&H used DEQ’s risk calculator (May 2019) to calculate potential cumulative risks for both residential and non-residential land use scenarios using the December 2019 cold weather data. H&H calculated the cumulative risks under a worst-case scenario, using the highest concentration of compounds detected in the December 2019 sub-slab vapor samples regardless of sample location. The results of the risk calculations are summarized below and are included in Appendix C. Land Use Scenario Calculated Cumulative LICR Calculated Cumulative HI Calculated LICR or HI Exceeds Acceptable Risk Levels? Residential 2.2 x 10-6 0.065 No Non-Residential Worker 1.7 x 10-7 0.0052 No As shown on the table above, the results of risk calculations using sub-sab vapor data under a worst- case scenario indicate a calculated LICR and HI below DEQ acceptable risk levels (LICR of 10-6 and HI of 1) for residential or non-residential land use scenarios. These results are consistent with the August 2019 warm weather vapor data in which there were also no exceedances of SGSLs or DEQ acceptable risk levels. As such, a vapor intrusion concern does not exist for the Site building. 7 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc 4.0 Receptor Survey Activities On December 31, 2019, H&H conducted receptor survey activities at the Site and nearby area. Receptor survey activities included an intensive pedestrian and vehicular survey for possible potable water supply wells, springs, and surface water intakes used as a source of water within a 1,500 ft radius of the Site. H&H also utilized the online geographic information systems, Mecklenburg County Well Information System 3.0 and DEQ Source Water Assessment Program (SWAP), to identify potential potable water sources for properties located within a 1,500 ft radius of the Site. In addition, H&H identified the locations of main underground and aboveground utilities, and land use and zoning adjacent to the Site using available Mecklenburg County online resources. A copy of the completed DEQ Brownfields Property Receptor Survey form is provided as Appendix D, and a receptor survey map is provided as Figure 3. The results of the receptor survey are summarized below. Site and Surrounding Properties As previously mentioned, the Site consists of an approximately 2.4-acre parcel of land that is developed with an approximate 65,136 sq ft industrial warehouse building. The central and eastern portions of the building were constructed in 1958, and the western portion of the building was constructed in the late 1970s. The Site buildings are currently vacant. The Site is located in a mixed-use area of Charlotte, North Carolina. Surrounding properties currently consist of the Penrose Apartments to the north, a multi-occupant commercial property to the northeast, a medical imaging equipment manufacturing facility to the east, Rampart Street, followed by an automotive repair facility and a mixed-use property under development (Hub South End) to the southwest, a dog boarding facility to the west, and commercial properties to the northwest. Zoning The Site is zoned as Transit-Oriented Development (TOD-UC). Adjacent properties to the south and east are also zoned as Transit-Oriented Development (TOD-UC). Adjacent properties to the north are zoned as Transit-Oriented Development (TOD-MO), while adjacent properties to the west and southwest are zoned as Transit-Oriented Development (TOD-NC). 8 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc Municipal Water Availability Municipal water supplied by Charlotte Water is available to the Site and surrounding area. H&H did not identify sources of public drinking water within 1,500 ft of the Site based on the DEQ SWAP’s and Mecklenburg County Well Information System 3.0 geographic information system maps. Based on the Annual Water Quality Report published by the City of Charlotte, the City of Charlotte obtains raw water from Lake Norman and Mountain Island Lake which are located approximately 15 miles north and 11 miles northwest of the Site, respectively. H&H observed the service area map published by Mecklenburg County which indicated that municipal water is available to the Site and the surrounding area within a 1,500 ft radius of the Site. Additionally, H&H observed municipal water meters for the Site and surrounding properties during receptor survey reconnaissance activities. Water Supply Wells H&H conducted a pedestrian and vehicular survey of properties within a 1,500 ft radius of the Site to identify potential water supply wells. H&H also utilized the DEQ SWAP’s geographic information system map to identify potential potable water supply wells located within a 1,500 ft radius of the Site. H&H did not identify private water supply wells within 1,500 ft of the Site. A water supply well was historically located at the subject Site, but it was abandoned by a NC- licensed well driller in December 2019. Surface Water Bodies Surface water bodies are not located at the subject Site. The closest water body is an unnamed tributary of Irwin Creek, located approximately 1,400 ft north of the Site. Based on the NC DEQ classification system, Irwin Creek is a Class C surface water body. A Class C surface water body is defined as “waters protected for uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including propagation, survival and maintenance of biological integrity, and agriculture. Secondary recreation includes wading, boating, and other uses involving human body contact with water where such activities take place in an infrequent, unorganized, or incidental manner.” Irwin Creek flows south through Mecklenburg County and discharges into Sugar Creek approximately three miles south of the Site. 9 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc Subsurface Structures H&H conducted a visual reconnaissance in the Site area to identify potential subsurface structures within 1,000 ft of the subject Site. H&H observed evidence of subsurface utilities including sanitary sewer, storm sewer, municipal water, natural gas, and/or communications utilities within or adjacent to Rampart Street (immediately south of the Site). The Site is serviced by natural gas. Electric service is primarily via overhead lines along Rampart Street. H&H did not observe structures with crawlspaces and/or basements within a 1,500 ft radius of the Site during visual reconnaissance. 10 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc 5.0 Conclusions and Recommendations H&H has completed Brownfields assessment activities on the Former Cotton Seed Oil Mill Brownfields Property (Brownfields Project No. 23053-19-060) located at 300 Rampart Street in Charlotte, Mecklenburg County, North Carolina. The assessment activities were conducted in accordance with the DEQ-approved Work Plan and included a receptor survey and sub-slab vapor sampling to evaluate potential environmental risks associated with redevelopment of the Site. A summary of the assessment results is provided below. Receptor Survey H&H conducted a Brownfields receptor survey for the Site and nearby area. The results of the receptor survey indicate that municipal water is available to the Site and area within a 1,500-ft radius of the Site. No sources of public drinking water were identified within 1,500 ft of the Site. An unnamed tributary of Irwin Creek is located approximately 400 ft east of the Site. H&H observed evidence of subsurface utilities, including sanitary sewer, storm sewer, municipal water, and natural gas on the Site and nearby adjacent properties. H&H did not identify obvious evidence of basements within a 1,000-ft radius of the Site. Sub-Slab Vapor H&H collected five sub-slab vapor samples (SSV-1 through SSV-5) within the Site building in cold weather conditions to further evaluate the potential for vapor intrusion. Laboratory analytical results did not indicate the presence of VOCs in the sub-slab vapor samples at concentrations exceeding Residential or Non-Residential SGSLs. H&H utilized DEQ’s risk calculator (May 2019) to calculate potential cumulative risks under a worst-case scenario at the Site using the cold weather condition data. The results of the risk calculations indicate that a vapor intrusion concern does not exist under residential or non- residential land use scenarios. 11 S:\AAA-Master Projects\JMC Holdings\JMC.009 300 Rampart Brownfields\Brownfields Assessment\Report\Brownfields Assessment Report_300 Rampart Street.doc Recommendations Based on the recent sub-slab vapor sampling results and the results of risk calculations, a vapor intrusion concern does not exist for the Site building under residential or non-residential use scenarios. As such, vapor mitigation is not warranted for the Site building, and no vapor mitigation plan is needed. H&H recommends completing an Environmental Management Plan (EMP) and obtaining DEQ approval for the EMP prior to subsurface disturbance.
