The certification The Sysco Charlotte, LLC. site is located at 4500 Corporate Drive in Concord, Cabarrus County, North Carolina. The property operates as a warehouse and food distribution facility and a tractor trailer fleet terminal. The site is covered by warehouse buildings, concrete, asphalt and grass. There is currently one 20,000-gallon diesel UST in use at the site with one associated dispenser and two satellite dispensers. On February 7, 2018, during a compliance inspection, the dispenser # 1/2 sump and the STP sump for the 20,000-gallon diesel UST were found to be defective. The non -passing sumps were repaired. Once repaired, the sumps were tested and the results were forwarded on to the North Carolina Department of Environmental Quality (NCDEQ). A site check was required according to the NCDEQ. On November 1, 2018, GRI conducted a site check in the vinicity of the dispenser # 1/2 sump and the STP sump for the 20,000-gallon diesel UST. Three soil borings (SB-1 to SB-3) were advanced approximately 3 feet below ground surface (bgs) immediately adjacent to the non -passing sumps associated with the dispenser # 1/2 and the 20,000-gallon diesel UST. Soil samples were collected at 3 feet (SB-1 (3') to SB-3 (3')). Upon receipt of the laboratory analytical results on November 9, 2018,.a reportable petroleum release was confirmed at the site. A contaminant concentration that exceeded the Regulatory Action Level (RAL) for TPH-DRO was reported in the soil sample collected from SB-2 adjacent to the sump at dispenser # 1/2 at the subject site. In addition, detectable contaminant concentrations that did not exceed the RAL for TPH-DRO were reported in SB-1 and SB-3. Based on this information, GRI recommends that a Limited Site Assessment be conducted at the site to determine if ground water has been affected. ii TABLE OF CONTENTS A.
