Problems/Comments
The Municipality of Anchorage anticipated purchasing the property in 7/89 from Sterling Investments, Seattle, WA. The Municipality removed USTs from the site in 10/89. Partial site remediation in the form of soil excavation has occurred. TPH in soils left in place ranged from less than 20 ppm to 104 ppm. Groundwater sample MW-4 taken in 7/89 had 590 ppb benzene, 1,770 xylenes and 3 ppb tetrachloroethene. Sample MW-1 had 3 ppb trichloroethene. No floating product documented. FKA L69.09

| 10/13/1989 | Release Investigation | SI; The Municipality of Anchorage retains Harding Lawson consultants to complete an environmental assessment of the site. ML&P is considering (7/89) purchasing the property from Sterling Investment Co. and Universal Services, Inc. Phase II of the assessment consisted of boring and placing 6 monitoring wells. Soil samples were collected from each boring. TPH in excess of 100 ppm occurred in 2 borings. Groundwater samples were colected from all 6 monitoring wells. Benzene at 0.590 ppm was encountered on 7/89 in well MW-4. Tetrachloroethene at 0.003 ppm was also detected in MW-4. | Former Staff |
| 10/26/1989 | Update or Other Action | REM; Harding Lawson was retained by the Municipality to remove the site's USTs. Analyses of soils remaining in place ranged from less than 20 ppm to 104 ppm TPH. The greatest BTEX was 0.52 ppm. Visual inspection of the USTs revealed heavy corrosion and multiple holes in tanks. Statewide Petroleum Services removed the USTs. No record of product being pumped from USTs prior to removal. Analytical samples from excavated soil stockpile (cubic yards not recorded) indicated disposal at the Anchorage Regional Landfill possible. | Former Staff |
| 4/15/1991 | Release Investigation | RELR; Sample results submitted reporting Benzene and xylenes present in groundwater at site at concentrations above standard limits. Benzene concentration at 590 ug/1 (standard is 5 ug/1) and total xylenes concentrations of 1,770 ug/1 (standard is 440 ug/1). Total petroleum hydrocarbon concentrations exceed ADEC action level of 100 mg/kg. | Former Staff |

| 1/27/2004 | Conditional Closure Approved | ADEC reviewed the September 2002 Groundwater Monitoring report prepared by ML&P. Based on the review and file information, a Record of Decision was prepared for the above referenced site that establishes cleanup levels and the determination that further remedial action is not required subject to site specific conditions and/or requirements. | Beatrice Egbejimba |
| 1/27/2004 | Institutional Control Record Established | Analytical methods used at the time of soil investigation were different from the current methods; therefore it is uncertain if any contaminants still remain in the soil at the former UST area at levels that may pose a risk to human health and/or the environment. However, current information indicates groundwater does not appear to be impacted. | Beatrice Egbejimba |
| 9/13/2006 | Update or Other Action | File number issued 2100.26.303 (FKA L69.09). | Aggie Blandford |
| 6/6/2013 | Long Term Monitoring Complete | Administrative action added during a quality control check. | Kristin Thompson |
| 9/3/2025 | Institutional Control Update | Responded to a request to move soil offsite that is taken from a driveway ramp in the vicinity of this site. This soil is not related to any contaminated soil remaining from this site's history. | Evonne Reese |
