Problems/Comments

On October 10, 1990, several surface oil stains were reported behind the building, around empty and full oil barrels, and around engine parts. Five-gallon cans of solvent cleaners were also found in the yard. On April 12, 1991 a highly damaged 55-gallon drum containing waste oil was reported. Total petroleum hydrocarbon (TPH) levels were 31,500 parts per million (ppm) and 4 cubic yards of soil were excavated and stockpiled on site. During this cleanup, the top half of a 500-gallon underground storage tank (UST) was found. Another area of concern is the Floor Drain. The maximum levels were extractable petroleum hydrocarbons (EPH) at 30,000 milligrams per kilogram (mg/kg), TPH at 59,000 mg/kg, lead at 980 mg/kg, and chromium at 55 mg/kg. These soils were thermally treated at Clean Soils in Anchorage. One of the stained surface contamination ran off onto adjoining property. Groundwater was encountered at 8 to 10 feet.

12/5/1995 Update or Other Action (Old R:Base Action Code = RPL3 - RP Determined and Action Request). Floor drain cleanup plan status request. By 1/15/96 a written verification that the cleanup plan approved by ADEC 3/14/94 will be implemented and a written schedule for the cleanup project and the name of the consulting firm overseeing the needed activities will be needed. Mike Krieber
6/20/1996 Cleanup Plan Approved (Old R:Base Action Code = CAPA - Corrective Action Plan). Reviewed a Corrective Action report. The department will not require any further assessment nor cleanup action related to floor drains in bays 1, 2, and 3. A treatment plan addressing remaining contamination and excavated soils with a time schedule is needed for department review and written approval. Mike Krieber
8/22/1996 Update or Other Action (Old R:Base Action Code = RAPA - Remedial Action Plan Approval). Reviewed a Stockpile Treatment and Disposal Plan and Stockpile Sample Results. The department requests a time schedule be submitted addressing cleanup at this property. Mike Krieber
1/3/1997 Update or Other Action Reviewed a Post-Treatment Sample Results Report. Sample results for the floor drain contamination are below regulatory levels. Therefore, the floor drain aspect of this site requires no further action by ADEC nor RP, however, unacceptable contamination levels remain for surface spills as well as heating oil tank related spills. The site will be totally closed when these 2 major remaining issues are addressed to the department's satisfaction. Mike Krieber

The site appears to be eligible for closure. Peter Campbell
