We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.


In December 2004, a 500-gallon used oil underground storage tank (UST) and associated piping were decommissioned. The UST was located within the Alaska Performance Machine Building on the east end. An excavation of approximately 11 feet by 11 feet by 9.5 feet deep was dug to remove the buried tank and the associated piping. Two confirmation soil samples were collected from underneath the former tank location and analyzed for GRO, DRO, RRO, BTEX. No contaminants were detected at levels that exceeded ADEC cleanup values.

11/10/2009 Cleanup Complete Determination Issued Following DEC’s review of BGES’s “Phase I Environmental Site Assessment and Underground Storage Tank Closure” dated December, 2004 DEC has determined no further assessment or cleanup action is required. The levels of contaminants of concern detected in soil do not exceed DEC’s most stringent cleanup levels established in 18 AAC 75.341 Method Two Tables B1 and B2. Groundwater and indoor air are not believed to be impacted since soil beneath the UST at 9.5 feet bgs was determined to not exceed Method Two “Migration to Groundwater” values established in 18 AAC 75.341. Therefore, there is no longer a risk to human health or the environment, and this site will be designated as closed. Todd Blessing
