Risk based corrective action: An application to closure of a fuel oil bunker site
An evaluation of the potential risk of adversely impacting the site ground water was conducted at a food processing facility in California. The facility stored fuel oil in a 50,000-gallon concrete bunker in addition to gasoline and kerosene tanks onsite. In response to an environmental impact assessment, a site remediation plan was implemented which consisted of removal of the concrete bunker and majority of the impacted soils to a depth of about 45 ft (13.72 m) below ground surface (bgs). Some of the soil samples collected at depths between 45 and 50 ft (13.72 and 15.24 m) indicated TPH levels as high as 5,275 mg/kg. A risk evaluation was conducted for a worst case scenario to document the fate and transport of the residual compounds reaching the shallow ground water flow system. It was demonstrated that the residual fuel oil present in the overlying soil did not impact the ground water at the time of investigation, and is not likely to have adverse impact on the shallow ground water beneath the site. Therefore, no further corrective action was needed and the site was closed.
