The approximate 4.99-acre site currently is identified by the Mecklenburg County Geographic Information System (GIS) website as Parcel Identification Number (PIN) 02502203 and owned by RJH Investments LLC. The subject property is currently developed with an approximate 5,880- square foot building that was constructed in 1971; an approximate 7,000-square foot building that was constructed in 1974; an approximate 15,300-square foot building that was constructed in 1978; and two approximate 7,500-square foot buildings that were constructed in 1987. The buildings are occupied by auto repair businesses, a lawn care business, and a motorsports fabrication business which includes storage space and offices. A Phase I Environmental Site Assessment (ESA) was previously completed by ECS on October 19, 2018 (ECS Project No. 49-7927). The findings of the Phase I ESA identified the following Recognized Environmental Conditions (RECs): • Based on the current use of the subject property, ECS considers the potential for an undocumented release at the subject property to be a REC of the subject property. • ECS observed an apparent septic tank system located on the western portion of the subject property. According to the property owner, Mr. Ron Hutcherson, there are approximately 5 or 6 septic tank systems at the subject property. He indicated that a septic tank services each building. There is the potential for waste oil and other fluids associated with the auto repair businesses to discharge into the septic system and drain field. ECS considers the potential for a release from the septic tanks to impact the subject property to be a REC of the subject property. • Based on the distance from the subject property and length of service, ECS considers the potential for an undocumented release migrating on to the subject site from the southern adjoining automotive repair facility to be a REC of the subject property. • ECS considers the potential for migration from the documented release involving the Parker Nall Well SWHS listing (solvent-impacted water supply well on the south adjoining property) to be a REC of the subject property. • ECS considers the potential for migration from the documented release associated with the Alterman Transport Lines, Inc. (west adjacent property) LUST incident to be a REC of the subject property. The following Historical Recognized Environmental Condition (HREC) was identified during this assessment: • ECS considers the RJH Enterprises LUST listing associated with a former heating oil UST to be a HREC of the subject property. The following Business Environmental Risks (BERs) were identified during this assessment: • ECS considers the potential for asbestos containing materials, lead in drinking water, lead based paint, mold, and wetlands at the subject property to be BERs for the subject site. Report of Environmental Assessment - Vaughn Gittin Jr. Motorsport Charlotte, Mecklenburg County, North Carolina RIMS No. 18-019638-01-2 ECS Project No. 49:8122-A 2 As part of a pending real estate transaction, ECS was contracted to conduct additional assessment to determine whether the RECs and HRECs identified in the Phase I ESA have impacted the subject property. Project information is based on correspondence between Mr. Varela with First Citizens Bank, Mrs. Erika Frey of ECS, and the previously cited Phase I ESA report. On November 8, 2018, ECS conducted a ground penetration radar survey (GPR) to locate potential septic tanks and drain fields and collected soil and groundwater samples from the subject site. The GPR survey confirmed the apparent septic tank system located on the western portion of the subject site identified during the Phase I ESA as well as an additional septic system located on the southern portion of the subject site. Four soil borings, SB-1 through SB-4, and three groundwater borings for temporary groundwater monitoring wells, TW-1 through TW-3, were advance at the site. The borings were located in the vicinity of the possible drain fields associated with the septic tank systems. The soil and groundwater samples were submitted to Prism Laboratories for analysis for volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and Resource Conservation and Recovery Act (RCEA) Metals using EPA Methods 8260, 8270, and 6010, respectively. Laboratory analysis of soil samples SB-1, SB-3, and SB-4 detected several VOCs and SVOCs at concentration above laboratory reporting limits but below their respective Preliminary Soil Remediation Goals (PSRGs) for residential and industrial/commercial sites. An estimated concentration of isophorone and a concentration of ¾-methylphenol were reported at a concentration above its protection of groundwater PSRG in soil sample SB-1. Concentrations of VOCS and SVOCS were not detected above the laboratory reporting limit in the soil sample SB-2. Laboratory analysis of each of the soil samples SB-1 through SB-4 detected concentrations of several RCRA metals above laboratory reporting limits. • Laboratory analysis of soil samples SB-1, SB-2, and SB-4 reported concentrations of arsenic above its residential PSRG but below its protection of groundwater PSRG. Laboratory analysis of soil sample SB-3 reported arsenic at a concentration above its residential and industrial/commercial PSRG but below its protection of groundwater PSRG. • Laboratory analysis of soil samples SB-2, SB-3, and SB-4 reported concentrations of total chromium above its protection of groundwater, residential, and industrial/commercial PSRG. Laboratory analysis of soil sample SB-1 reported total chromium at a concentration above its protection of groundwater and residential PSRG but below its industrial/commercial PSRG. • Laboratory analysis of soil sample SB-2 reported selenium at a concentration above its protection of groundwater PSRG but below its residential and industrial/commercial PSRG. Laboratory analysis of the groundwater sample collected from temporary monitoring wells TW-2 and TW-3 detected several targeted VOCs at concentrations above laboratory reporting limits. Benzene was detected in the groundwater sample collected from temporary monitoring well TW-2 at a concentration (2 micrograms per liter (µg/l)) above its North Carolina 2L Groundwater Quality Standard (NC2LGWQS) (1µg/l) but below its groundwater screening level for vapor intrusion (GWSL) at residential and non- residential sites. Acetone, a common laboratory contaminant, was detected in the groundwater sample collected from temporary monitoring wells TW-1 and TW-3 at concentrations below its NC2LGWQS. Report of Environmental Assessment - Vaughn Gittin Jr. Motorsport Charlotte, Mecklenburg County, North Carolina RIMS No. 18-019638-01-2 ECS Project No. 49:8122-A 3 Several RCRA metals were detected in the groundwater samples collected from temporary monitoring wells TW-1 through TW-3 at concentrations above the laboratory reporting limit but below their respective NC2LGWQS. Concentrations of targeted SVOCs were not detected above the laboratory reporting limit in the groundwater samples collected from each of the temporary monitoring wells. ECS noted that the buildings on-site reportedly utilize an active private water supply well and are not connected to municipal water or sanitary sewer. Additionally, the site contains numerous ASTs which were used to contain heating oil. In 2008, a 1,000-gallon heating oil UST and approximately 30.33 tons of petroleum-impacted soil was excavated. Confirmatory soil samples were collected from the base and the side was of the excavation. The soil samples did not exceed the soil to groundwater standard for the targeted constituents. No groundwater or surface water samples were collected for this assessment. On July 17, 2018, the NCDEQ issued this facility a letter of No Further Action. According to the letter the soil contamination did not exceed the lower of the soil to groundwater or residential maximum soil contaminant concentrations (MSCCs). The source of the release is undetermined and warrants further investigation. ECS has been requested to conduct additional assessment activities in an effort to investigate the contaminant exceedances at the subject site. 2.0 SCOPE OF SERVICES The environmental assessment included the collection of soil and groundwater samples, the completion of a relative temporary monitoring well survey, and the submittal of the previously collected soil samples for analysis of hexavalent chromium. Drilling activities were conducted using a Geoprobe® drill rig. The drilling subcontractor used for this assessment was 3D Environmental Investigations, LLC (3D). Drilling and sampling were conducted on December 3, 2018. A photographic log documenting the field sampling activities is provided in Appendix A. 2.1 Public Utility Locate Prior to commencing with field activities, ECS contacted North Carolina One-Call to locate/mark public utilities at the site. Required separation distances between subsurface activities and marked utilities (typically 30-inches) were maintained during the field activities. 2.2 Monitoring Well Permit Prior to commencing with field activities, ECS obtained a monitoring well permit from the Mooresville Regional office of the North Carolina Department of Environmental Quality (NCDEQ). In accordance with the NCDEQ permit, the GW-1 and GW-30 forms (well construction and well abandonment forms) were submitted to the NCDEQ. The GW-1 and GW-30 forms were completed by the North Carolina certified well driller. 2.3 Private Utility Locate The private utility locate was conducted by Priority Underground Utility Locate across the subject property as North Carolina One-Call does not mark private utilities. Report of Environmental Assessment - Vaughn Gittin Jr. Motorsport Charlotte, Mecklenburg County, North Carolina RIMS No. 18-019638-01-2 ECS Project No. 49:8122-A 4 2.4 Soil Boring Activities Three soil borings, SB-5, BKG-1, and BKG-2, was advanced at the site in the vicinity of the former soil boring SB-1 and in two discrete background locations. The boring/sample locations are depicted on Figure 3. The soil borings were advanced by hydraulically driving a five-foot long, 1.5-inch diameter soil sampling probe into the soil to a depth of 15 feet below the ground surface (bgs). Continuous soil samples were collected from the soil borings using a soil sampling probe lined with a dedicated disposable clear plastic tube. After the soil sampling probe was driven, the clear plastic tube filled with soil was removed from the probe and cut open to expose the soil. ECS visually classified the soil collected and screened the soil samples for relative levels of volatile organic vapors using a photoionization detector (PID). Soil samples were collected from the bottom of the boring (10-15 feet bgs) of SB-5 in an effort to vertically delineate the previously identified soil impacts. Soil samples were collected at random from the two background boring locations (BKG-1 and BKG-2). 2.5 Temporary Monitoring Well Installation Activities After soil sampling activities were complete, three borings were advanced to the water table for the installation of temporary monitoring wells. Temporary monitoring well TW-4 was advanced in the vicinity of the former TW-2 boring while TW-5 and TW-6 were advanced in more central locations of the site. The locations of the temporary groundwater monitoring wells are shown on Figure 3. The temporary monitoring wells were installed in boreholes drilled using a Geoprobe® in a manner consistent with the borings described above. The temporary wells were constructed with one-inch inside diameter Schedule 40 PVC flush-threaded casing and screen. Temporary monitoring wells TW-4 through TW-6 were set to a total depth of 30 feet bgs. A fifteen-foot length of slotted well screen with machined 0.010-inch slot widths and a threaded bottom plug was installed at the bottom of each well. The screens were installed to a depth that intercepted the groundwater surface, as estimated during drilling, or at the top of drilling refusal. Upon the completion of the temporary monitoring well installation activities, a top of casing (TOC) survey was conducted in an effort to determine the relative direction of groundwater flow across the site. Following the completion of the groundwater sampling and surveying, the temporary monitoring wells were removed and the borings were properly abandoned. 2.6 Soil and Groundwater Sample Collection The soil samples were collected by a sampler wearing dedicated disposable nitrile gloves from the clear plastic tubes retrieved from the soil sample probe. New sleeves were used for each sample. The soil samples were placed directly into laboratory provided containers. Groundwater was purged and sampled subsequent to being pumped to the surface using a peristaltic pump with dedicated disposable polyethylene tubing lowered through the temporary monitoring well casing. Groundwater samples were placed directly into laboratory prepared containers at each sample location. Report of Environmental Assessment - Vaughn Gittin Jr. Motorsport Charlotte, Mecklenburg County, North Carolina RIMS No. 18-019638-01-2 ECS Project No. 49:8122-A 5 The soil and groundwater sample containers were labeled with ECS project number, sample identification, sample date and time, and requested analytical analysis. The containers were placed into a cooler with ice to maintain the samples at approximately 4° Celsius. The soil and groundwater samples were submitted to Prism Laboratories for analysis. The soil sample collected from SB-5 was submitted for analysis of semi-volatile organic compounds (SVOCs) using EPA Method 8270, while the two background soil samples (BKG-1 and BKG-2) were submitted for analysis of arsenic and selenium using EPA Method 6010. The groundwater samples were submitted for laboratory analysis of volatile organic compounds (VOCs) and SVOCs using EPA Methods 8260 and 8270. Additionally, the previously collected soil samples SB-1 through SB-4 were re-submitted for laboratory analysis of hexavalent chromium using EPA Method 7199. 3.0 RESULTS 3.1 Soil Analytical Results Laboratory analysis of the soil sample collected from SB-2 detected hexavalent chromium at an estimated concentration of 0.48 mg/kg which is above the NCDEQ Residential Health Based PSRG of 0.31 mg/kg. Hexavalent chromium was detected in each of the other soil borings at estimated concentrations below the NCDEQ Residential Health Based PSRG. Arsenic was detected at a concentration of 6.2 mg/kg is the soil sample collected from BKG-1 which is above the NCDEQ Industrial/Commercial Health Based PSRG of 3.0 mg/kg and the NCDEQ Protection of Groundwater PSRG of 5.8 mg/kg. Arsenic was detected at a concentration of 4.2 mg/kg in the soil sample collected from BKG-2 which is above the Industrial/Commercial Health Based PSRG but below the Protection of Groundwater PSRG. Selenium was detected at concentrations ranging from 5.1 mg/kg (BKG-2) to 5.6 mg/kg (BKG-2) which is above the Protection of Groundwater PSRG of 2.1 mg/kg, but below the Residential Health Based PSRG of 78 mg/kg. Laboratory analysis of the soil sample collected from SB-5 detected ¾-methylnaphthalene at an estimated concentration of 0.13 mg/kg, which is below the NCDEQ Protection of Groundwater and Residential Health Based PSRGs of 17 mg/kg and 1,300 mg/kg. A summary of the soil analytical results are provided on Table 1. The laboratory data sheets are included in Appendix B. 3.2 Groundwater Analytical Results Laboratory analysis of each of the groundwater samples (TW-4 through TW-6) detected tetrachloroethylene, a chlorinated solvent, at concentrations ranging from 0.98 ug/L (TW-6) to 6.8 ug/L (TW-5), which is above the NC2LGWQS of 0.7 ug/L, but below the NCDEQ Residential Vapor Intrusion Screening Level (VISL) Groundwater Screening Level (GWSL) of 12 ug/L. Additionally, several other VOCs were detected in the groundwater sample collected from TW-6 at concentrations exceeding their respective NCDEQ Residential VISL GWSLs and NC2LGWQSs. Acetone, a common laboratory contaminant, was detected at a concentration below its applicable standards in the groundwater sample collected from TW-5. Report of Environmental Assessment - Vaughn Gittin Jr. Motorsport Charlotte, Mecklenburg County, North Carolina RIMS No. 18-019638-01-2 ECS Project No. 49:8122-A 6 4.0 CONCLUSIONS Based on the results of the environmental assessment, ECS concludes the following: • It appears that the soil impacts previously identified in SB-1 have been vertically delineated to below the applicable screening levels at a depth of 10-15 feet via the soil sample collected from SB-5. • Based on the consistency of the detections of arsenic and selenium in the background soil samples collected (BKG-1 and BKG-2) to that of the soil samples previously collected, the detections of arsenic and selenium appear to be consistent with naturally occurring concentrations of arsenic and selenium. • Based on the detection of hexavalent chromium in the soil sample collected from SB-2 at a concentration exceeding the NCDEQ Residential Health Based PSRG but below the Protection of Groundwater and Industrial/Commercial Health Based PSRG, it appears that the site has been impacted where the soil sample was collected. • Based on the results of the relative site survey, groundwater appears to be flowing to the south- southeast. • Based on the detections of tetrachloroethylene in each of the wells, and various other VOCs in the anticipated upgradient well at concentrations exceeding their applicable NC2LGWQSs and NCDEQ Residential VISL GWSLs (but below the NCDEQ Non-Residential VISL GWSLs), it appears that groundwater at the site has been impacted by either onsite operations or a potential upgradient source. 5.0 RECOMMENDATIONS Based on the results of the environmental assessment, ECS recommends the following: • ECS understands that based on the detections of contaminants in soil and groundwater at the site, a reporting obligation to the NCDEQ may exist. ECS recommends a copy of this report be submitted to the property owner and they consult legal counsel regarding potential reporting obligations. • ECS does not recommend additional assessment of the arsenic and selenium detections at the site. • Based on the proposed commercial/industrial redevelopment activities, it does not appear that additional assessment is warranted for the identified soil impacts.
