Problems/Comments

After DGS determined it was unlikely the UST would pass tightness testing requirements for regulated tanks they submitted a UST Taken Out-of-Service or Temporary Closure form and Empty Tank Affidavit to the DEC Storage Tank Program. DGS then contacted Carson Dorn (CDI) Inc. to perform a regulated UST site assessment in conjunction with the tank closure-by-removal excavation scheduled to take place in June 2009. In accordance with 18 AAC 78.090(d)(1), CDI determined that the UST and piping were in good condition with no indication of a release, the soil consisted of D1 fill and groundwater was not present. In accordance with 18 AAC 78.090(2)(B), CDI collected soil confirmation analytical samples PSB-1 and PSB-3 at depths below ground surface (BGS) of seven and one half feet at the north and south ends of the tank respectively. Directed using PID readings, CDI then collected sample PSB-2 at depths BGS of seven and one half feet near the midsection of the tank on its east side, and sample PSB-4 at a depth BGS of two and a half feet beneath the piping from the remote fill port. The only soil sample that exceeded a laboratory reporting limit was PSB-3 and the result was a DRO concentration of 72.3 milligrams per kilogram (mg/kg). This is the highest level of petroleum detected in soil remaining at the site.
