Problems/Comments
A 10,000 gallon underground storage tank (DEC ID: UST #4; Owner ID: 4A/4B) system was excavated and removed from the ground at the Pepsi Cola Warehouse on July 18, 2017. The tank was reportedly installed in 1992 and was known to have contained diesel fuel. During excavation activities, diesel range organics (DRO) contaminated soil was encountered beneath the northern fuel pump area above DEC cleanup levels. The contaminated soil was excavated and removed from the area until no further DRO contamination above DEC cleanup levels remained. Contaminated soil was disposed of at Alaska Soil Recycling, and the clean excavated soil was re-used as backfill.

| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 8/21/2017 | Leaking Underground Storage Tank Cleanup Initiated - Petroleum | Diesel range organics (DRO) contamination was encountered in soil during the excavation and removal of a 10,000 gallon underground storage tank (UST) at the Pepsi Cola Warehouse. This UST was installed in 1992 and had been used as a diesel refueling station. During initial excavation activities, the contamination was identified beneath the northern fuel pump area by a photoionization detector reading of 62 parts per million. Analytical samples confirmed the DRO to be above ADEC cleanup levels with the highest level of contamination reaching a maximum of 408 milligrams per kilogram (mg/kg). Personnel mobilized to the site an additional two times (August 15th and August 21st) to remove remaining contaminated soil. Analytical samples collected after the final excavation effort exhibited contaminant concentrations below applicable ADEC cleanup levels. | Sammi Castle |
