Problems/Comments
Two UST's, one 3,000 gallon diesel UST, and one 1,000 gallon used oil UST, and a pump island were removed from this site in 1997. Another 3,000 gallon gasoline UST was reportedly removed in the late 1980s, however, no data was collected at the time of this excavation. Approximately 35 cubic yards (cy) of DRO contaminated soil was stockpiled, and roughly 50 cy of soil was returned to the excavations this soil contained up to 2,100 mg/kg DRO and 3,200 mg/kg RRO. Additional information regarding potential contamination at this facility is tracked under the following Contaminated Sites Program database records: Hazard ID 26558, file number 2215.38.030 - Class V injection well. Hazard ID 1305, file number 2215.38.023 - 2005 removal of 20,000-gallon used-oil partially buried tanker car.

| 6/21/2004 | Leaking Underground Storage Tank Cleanup Initiated - Petroleum | The file for this site was located in Fairbanks. in 1997, a 3,000 gallon diesel UST, a 1,000 gallon used oil UST, and pump island were removed. Another 3,000 gallon gasoline UST was reportedly removed in the late 1980s; no data available. Approximately 35 CY of DRO soil was stockpiled. Approximately 50 CY of soil was returned to the excavations- it contained up to 2,100 mg/kg DRO and 3,200 mg/kg RRO. A 20,000 gallon partially buried tanker car containing used oil was not characterized. | Sharon Richmond |
| 8/10/2004 | Leaking Underground Storage Tank Corrective Action Underway | ADOT contacted DEC to request approval to use soil with low to moderate DRO contamination as road-bed fill. Request was approved but soil was later found to contain pieces of metal that made it unsuitable to process with the rock crusher. Soil will be stockpiled pending approval of treatment method. | Sharon Richmond |
| 8/11/2004 | Update or Other Action | Mark Lockwood called to update PM on site status. Soil will be stockpiled. Possible land farming site avaialble at out of use nearby gravel pit. Sampling report pending | David Allen |
| 1/10/2005 | Update or Other Action | GIS Update, Topozone Pro, Nad83 | Kim DeRuyter |
| 9/21/2005 | Document, Report, or Work plan Review - other | Received UST assessment report. Soil samples taken this summer indicate that soil beneath tanks 1-3 do not exceed ADEC soil cleanup levels. The tanker car was decommissioned and removed from the site this summer. Approximately 500 cubic yards of contaminated soil was excavated and landspread at the Locke Salvage site. MWs downgradient of the former tanker car contained TCE and cis-DCE in excess of cleanup levels. 3 samples of the onsite drinking water well did not contain analytes exceeding their PQLs, or ADEC cleanup levels. | Kim DeRuyter |
