A developer for a fast food restaurant chain purchased a site located in Wilson, NC. The site was initially a petroleum retail facility, then later housed a steak house for 20 years prior to being purchased by the developer. While beginning pre-construction activities, the developer discovered six abandoned Underground Storage Tanks (USTs) of unknown contents. Geological Resources, Inc. (GRI) was called in to coordinate the removal of the abandoned USTs from the site.
A developer for a fast food restaurant chain purchased this site located in Wilson, NC. The site was initially a petroleum retail facility, then later housed a steak house for 20 years prior to being purchased by the developer. While beginning pre-construction activities, the developer discovered six abandoned Underground Storage Tanks (USTs) of unknown contents: three 3,000-gallon, two 2,000-gallon and one 550-gallon USTs. Geological Resources, Inc. (GRI) was called in to coordinate the removal of the abandoned USTs from the site.
While beginning pre-construction activities, the developer discovered six abandoned Underground Storage Tanks (USTs) of unknown contents: three 3,000-gallon, two 2,000-gallon and one 550-gallon USTs.
Concentrations of requested method constituents that exceeded the Regulatory Action Levels (RALs) were reported in soil samples, therefore, limited over excavation activities were conducted in the vicinity of the former UST basins. Those concentrations were also reported in the confirmation samples, but did not exceed the Residential Soil Cleanup Levels. When ground water was encountered during the activities, a monitoring well was installed in the former UST basin and sampled. Concentrations of requested method constituents that exceeded the Maximum Allowable Concentrations (MACs) were reported, but did not exceed the Gross Contamination Levels (GCLs).
Three water supply wells were identified within a 1,500-foot radius of the site during the receptor survey, but none within a 250-foot radius of the site. There were no potable water supply wells identified within a 1,000-foot radius and no surface water bodies within a 500-foot radius of the site. The site was not located within a designated wellhead protection area.
Although a release was noted, in discussions with the North Carolina Department of Environmental Quality (NCDEQ) it was determined that the incident would be classified low risk. The monitoring well was properly abandoned and a Notice of Residual Petroleum (NRP) for ground water was filed on the property’s deed.
The incident was closed with a No Further Action (NFA) letter.
