Problems/Comments

Impacted soil (approximately 55 cu. yds) from heating oil UST 46-C-6, decommissioned in 1991, was landfarmed at NDB. Results of confirmation samples collected and analyzed in 1991 documented that 3,500 mg/kg oil content remained in soil at 7 ft below ground surface. All contaminated soil was excavated during tank decommissioning. In 2003, ADEC recommended site characterization be completed prior to any necessary cleanup actions and closure. Closure requested by FAA on 1/23/04.

Action Information

Action Date Action Description DEC Staff
1/1/1991 Leaking Underground Storage Tank Cleanup Initiated - Petroleum UST 46-C-6 was removed along with 55 cubic yards of potentially contaminated soil in 1991. FAA requested site closure in 1994. PM mis-read the sample results, and didn't realize that the excavation was continued until clean samples were obtained. FAA sent a letter explaining the error, and the data was re-evaluated in 2008.
