Kentucky Underground Storage Tank (UST) Removal – No Further Action Issued by Kentucky USTB

During a Phase II Environmental Site Assessment (ESA) of an actively leased commercial/industrial property in Kentucky, an undocumented underground storage tank (UST) was identified. Sample results of surrounding soils, collected by the prior consultant, indicated a possible release from the UST. Prior to becoming a commercially leased property, the owner operated the site as a service center for an electric company which housed equipment and materials dating back to the 1950’s. The Phase II ESA was conducted as part of the property transaction process. Based on the Phase II ESA results and resale requirements, the seller was responsible for the identification and removal of the UST and remediation of impacted media before the sale could be completed.

Based upon a professional referral, Cox-Colvin & Associates was contracted to complete the UST closure in a timely manner. Activities were performed two days after approval of the permanent closure application by the Kentucky Department for Environmental Protection (KDEP). Closure activities were conducted in accordance with the Kentucky Underground Storage Tank Branch’s (USTB’s) UST Corrective Action Manual and applicable Division of Waste Management requirements. The 1,000-gallon steel UST was found to contain 700-gallons of degraded gasoline and water. Finger-sized and smaller holes in the bottom of the tank confirmed the suspected release of contents. Field experience in contaminant migration, coupled with effective professional judgment, and a skilled excavator limited the volume of soil removed to 24 tons. Sufficient cleanup was verified thorough confirmation sampling. The removal and cleanup activities were accomplished in two days with minimal disturbance to the actively leased property. Upon receipt of confirmation sample results, a formal Closure Assessment Report was submitted to the Kentucky USTB providing sufficient evidence that clean-up standards were met, allowing the property transaction to move forward with minimal interruption.
