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.

| 3/21/2014 | Cleanup Complete Determination Issued | With information currently available, DEC has determined there is no unacceptable risk to human health or the environment as long as any remaining contamination at the Site is properly managed. Two conditions are necessary for the corrective action complete determination and must be closely adhered to. If disturbance is planned in any of the areas of the property described in this letter as having residual contamination, a work plan must be submitted for DEC approval prior to any such site activity begins. Any proposal to transport soil or groundwater off-Site requires DEC approval in accordance with 18 AAC 78.600(h). A “site” [as defined by 18 AAC 75.990 (115)] means an area that is contaminated, including areas contaminated by the migration of hazardous substances from a source area, regardless of property ownership. Movement or use of contaminated material in a manner that results in a violation of 18 AAC 70 water quality standards is prohibited. This determination is in accordance with 18 AAC 78.276(f) and does not preclude DEC from requiring additional assessment and/or cleanup action if future information indicates that conditions at the Site may pose an unacceptable risk to human health or the environment. | Bruce Wanstall |
