Problems/Comments
One underground storage tank was removed at this residence in 1995 as documented in the Fuel Storage Tank Decommissioning Assessments, dated 1995. Tank 9-C-8 was an active 500 gallon diesel tank that was removed and 15 cubic yards of petroleum-contaminated soil were removed. Six (6) confirmation samples were collected and analytical results showed that diesel-range organics concentrations up to 3,000 mg/kg remained in place due to its proximity to the building. A soil boring advanced during the 1996 Remedial Investigation showed contamination present by field screening at seven (7) feet below ground surface, but an analytical result of non-detect for diesel-range organics at nine (9) feet below ground surface. A no further remedial action planned letter was issued by the department for this tank on November 27, 1995.

Tank 9-C-8, an active 500 gallon diesel tank, was removed along with 15 cubic yards of petroleum-contaminated soil in 1995. Six confirmation samples were collected and showed that diesel-range organics concentrations up to 3,000 mg/kg remained in place due to its proximity to the building. A soil boring advanced during the 1996 Remedial Investigation showed contamination present by field screening at seven feet bgs, but an analytical result of non-detect for DRO at nine feet bgs. ADEC is concerned with the possibility that the vapor intrusion pathway is potentially complete as this building is currently used as a residence. ADEC requests that FAA conduct modeling or soil gas or air monitoring to determine if vapor intrusion is a concern. ADEC letter dated November 21, 2005. | Anne Marie Palmieri |
| 4/10/2009 | Cleanup Complete Determination Issued | A no further remedial action planned letter was issued by the department for this tank on November 27, 1995. | Debra Caillouet |
