Problems/Comments
In 1997, two 2,500 gallon gasoline USTs and one 5,000 gallon diesel UST were removed. Levels of DRO and lead remain at limits of excavation and underneath dispenser island 6 feet bgs (up to 3,200 mg/kg DRO & 380 mg/kg lead) and levels of benzene were detected below the gasoline tank at .057 mg/kg. Groundwater was not encountered. Approximately 45 cubic yards of soil was stockpiled on site. The stockpile was not located during an an ADEC site visit in 2009. The fate of the stockpile is unknown. The vertical and horizontal extent of contamination has not been evaluated. Currently, an AST fueling facility is located at the former UST area.

| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 3/9/1998 | Document, Report, or Work plan Review - other | On this date, ADEC received Final Field Report Underground Storage Tank Removal Palmer Facility ADOT&PF Central Region, dated February 1998, submitted by Dowl. Three USTs: a 5,000 gal. diesel, and two 2,500 gal. gas; were removed west of the ADOT&PF Shop Building on July 23, 1997. Nine soil samples were collected: six confirmation samples collected from the depths of the USTs excavation, at 6ft. to 8 ft. bgs, (two per UST), one below the former dispenser, and two from the stockpile. The former USTs confirmation samples contains DRO up to 2,500 mg/kg and up to 0.057 benzene. The former dispenser sample contains DRO up to 3,200 mg kg and lead up to 380 mg/kg. Soil samples from the stockpile contains DRO up to 2,000 mg/kg. The excavation was then backfilled with PID segregated “clean” soil from the excavation, and imported clean fill. Approximately 45 cubic yard contaminated soil stockpile remains on site. Groundwater was not encountered during excavations. | Grant Lidren |

| 6/9/2009 | Site Visit | ADEC met on site with ADOT&PF. The soil stockpile could not be located. Also, an AST is currently located in the area of the former USTs. | Grant Lidren |
| 5/1/2014 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 77883 three USTs. | Joshua Barsis |
| 9/29/2015 | Update or Other Action | On August 26, 2015, a release was discovered from a 4,000-gallon diesel above ground storage tank (AST) at the Alaska Department of Transportation & Public Facilities (ADOT&PF) Palmer Maintenance Facility. The spill was originally reported to the Prevention Preparedness and Response program on August 31, 2015; however, oversight of the spill was transferred to the Contaminated Sites Program (CSP) because the release occurred in the same location as the active contaminated site, the ADOT&PF - Palmer Maintenance Facility site. Samples were collected from a small excavation on September 9, 2015 for the purpose of documenting remaining contamination. Not all contamination was removed because of time restrictions. The AST needed to be returned to its original location over top of the historic contamination for operation. All sample results (except two) exceeded the ADEC migration-to-groundwater (MTG) cleanup level for DRO, but were below ingestion and inhalation cleanup levels. The maximum reported concentration of DRO remaining in the excavation was 9,010 mg/kg. GRO was present up to 417 mg/kg. All other compounds were either non detected above laboratory limits of quantitation, or were below ADEC MTG cleanup levels. Please see internal report for more information. | Joshua Barsis |
| 11/4/2016 | Update or Other Action | Send letter on this day with brief site history and to outline existing data gaps that need to be addressed before this site could be considered for closure. | Joshua Barsis |
