This project is associated with the nearby North Carolina Department of Transportation (NC DOT) Charlotte Gateway Station and Track and Safety Improvements project. The UST removal activities were conducted on behalf of the NC DOT. A site location map is included as Figure 1, and a site map is included as Figure 2. As part of construction activities associated with the Charlotte Gateway Station project, the former Greyhound bus station (currently located at 601 W. Trade Street) was relocated to the southwestern portion of the City of Charlotte property (tax parcel 07315110) located at 518 W. 4th Street. During construction of the new Greyhound facility non -hazardous impacted soil that was removed from the new Greyhound site was temporarily stockpiled on the northeastern 2923 5outh Tryon Street, Suite 100 3921 Sunset Ridge Rd, 5uite 301 Charlotte, NC 28203 Raleigh, NC 27607 www.harthickman.com 704.586.0007 main 919.847.4241 main Mr. Gordon Box, LG September 30, 2019 Page 2 portion of the City of Charlotte property. During removal of the stockpiled soil, the top of an approximate 2,000-gallon heating oil UST was encountered in the northeastern portion of the property. The UST was removed from the site on June 17, 2019. Based on field observations, the UST apparently contained heating oil. The former UST location is shown on Figure 2. The UST removal activities are discussed below. 2.0 UST Removal Activities At the request of NC DOT, H&H contracted with EVO Corporation (EVO) of Winston-Salem, North Carolina to remove the UST. H&H obtained a fire permit from the Charlotte Fire Department prior to removal of the UST. A copy of the fire department permit is included in Appendix A. On June 17, 2019, EVO mobilized to the site to remove the UST. Prior to removing the UST, H&H directed EVO to access the UST and measure the amount of liquids in the tank. Approximately 125 gallons of wastewater and heating oil were removed from the UST using a vacuum truck. The liquids were properly disposed by EVO. The certificate of disposal and non- hazardous materials manifest for removed liquids are included in Appendix B. Following removal of the residual liquids, a lower explosion level (LEL) meter was utilized to monitor for explosive atmospheres in the UST. LEL measurements within the UST were less than 10% of the LEL. Prior to the removal of the tank, soil was removed from the top and sides of the UST with an excavator so that the UST could be removed from the ground. Soil encountered during the excavation was evaluated in the field for the presence of odors, staining, and organic vapor readings as detected with a photoionization detector (PID). The PID was calibrated prior to its use against an isobutylene standard. hart ` hickman S:\AAA-Master Projects\NC DOT Right-of-Way-ROW\ROW-500s\ROW-516 Gateway Station Soil\UST Reports\Tank 3\Report\P-5705B_UST Removal Activities_ Gateway Station_20190930.doc SMARTER ENVIRONMENTAL SOLUTIONS Mr. Gordon Box, LG September 30, 2019 Page 3 Following removal of the tank, the UST was inspected for evidence of holes, pitting, and corrosion. Corrosion, small holes, and pitting were observed in the UST. The UST was approximately 2,000-gallons in capacity and was constructed of steel. With the exception of approximately two feet of small diameter copper piping on top of the tank, no other piping was observed near the UST location. Following removal, the UST was transported off -site by EVO to Foss Recycling in Winston-Salem, NC, for proper disposal and recycling. The tank disposal certificate is included in Appendix C. UST Closure Sampling Elevated PID readings (up to approximately 100 ppm) were measured in soil samples collected beneath the former UST location. Because there was evidence of a release, UST closure samples were collected in accordance with the NC DEQ UST Section Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases, March 1, 2007 Version, Change 9, Effective February 1, 2019 (Guidelines). Closure soil samples (C-1 and C-2) were collected beneath the former UST location using the excavator bucket. The samples were placed into laboratory supplied sample containers, placed in an iced cooler, and submitted to Pace Analytical Services, LLC, under standard chain of custody protocol for analysis of total petroleum hydrocarbons (TPH) as gasoline range organics (GRO) and as diesel range organics (DRO) by EPA Method 8015. For each sample, additional soil was placed on hold with the laboratory for potential risk -based analysis of volatile organic compounds (VOCs) by EPA Method 8260, semi-VOCs (SVOCs) by EPA Method 8270, and extractable petroleum hydrocarbons (EPH) and volatile petroleum hydrocarbons (VPH) by the Massachusetts Department of Environmental Protection (MADEP) Methods pending the TPH DRO and GRO results. The laboratory analytical data report and chain of custody record are provided in Appendix D. Analytical Results Laboratory analytical results indicate concentrations of TPH-DRO (5,980 mg/kg and 7,230 mg/kg) in soil samples C-1 and C-2, respectively. The TPH-DRO concentrations exceed the NC hart ` hickman S:\AAA-Master Projects\NC DOT Right-of-Way-ROW\ROW-500s\ROW-516 Gateway Station Soil\UST Reports\Tank 3\Report\P-5705B_UST Removal Activities_ Gateway Station_20190930.doc SMARTER ENVIRONMENTAL SOLUTIONS Mr. Gordon Box, LG September 30, 2019 Page 4 DEQ Action Level of 100 mg/kg. No TPH-GRO was detected in the closure soil samples. At the direction of NC DOT, soil sample C-2 (with the highest DRO detection), was also analyzed for the risk -based analyses noted above. Low level concentrations of 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, m&p-xylenes, fluoranthene, and pyrene were detected in sample C-2 below their respective NC DEQ Maximum Soil Contaminant Concentrations (MSCCs). A concentration of Total C9-C22 Aromatics (231 mg/kg) was detected in sample C-2 above the Soil -to -Groundwater MSCC of 31 mg/kg. Soil sample analytical results, analytical methods, and sample depths are summarized in Table 1. The UST closure sample locations and analytical results are depicted on Figure 2. Based on field screening results, only impacted soil that was required to be excavated to remove the tank from the ground was properly disposed by EVO. Approximately 8.33 tons of impacted soil were transported to EVO's facility in Winston-Salem, NC for proper treatment/disposal. As directed by NC DOT, no over excavation of impacted soil was conducted during UST closure activities. The certificate of disposal, non -hazardous materials manifest, and certified weight ticket for removed impacted soil are included in Appendix E. After closure sampling, the excavation was backfilled with clean soil provided by EVO. 3.0 Risk Evaluation Because laboratory analytical results of UST closure samples indicate target constituents above the NC DEQ Action Level and the MSCCs, additional site information was obtained by H&H to help determine the site risk. The site is situated in Uptown Charlotte within the I-277 loop. H&H reviewed the Mecklenburg County Groundwater & Wastewater Services (GWS) online Well Information System map and conducted a visual survey to identify potential water supply wells located near the site. No water supply wells were identified within a 150 ft radius of the former heating oil UST source area. No schools, daycares, assisted living, houses of worship or other potential receptors of concern were identified on properties adjacent to the site. A new Greyhound bus station was recently constructed on the southwestern portion of the site. Based on these findings, the site risk is judged to be low. hart ` hickman S:\AAA-Master Projects\NC DOT Right-of-Way-ROW\ROW-500s\ROW-516 Gateway Station Soil\UST Reports\Tank 3\Report\P-5705B_UST Removal Activities_ Gateway Station_20190930.doc SMARTER ENVIRONMENTAL SOLUTIONS Mr. Gordon Box, LG September 30, 2019 Page 5 4.0 Conclusions and Recommendations H&H has completed UST removal activities on the City of Charlotte property located at 518 W. 4th Street near the Charlotte Gateway Station and Track and Safety Improvements project. An approximate 2,000-gallon heating oil UST was encountered during removal of a soil stockpile associated with construction of the adjacent Greyhound facility. Based on field screening and visual observations, evidence of impacted soil was identified beneath the UST. Laboratory analytical results of UST closure samples indicate concentrations of target constituents above the NC DEQ Action Level and Soil -to -Groundwater MSCCs. Approximately 8.33 tons of impacted soil were properly disposed during UST closure activities. Because no potential receptors were identified on the site and adjacent properties, the site risk is judged to be low. H&H recommends that a copy of this report be provided to the North Carolina Department of Environmental Quality.
