The C.R. Lewis site is located at 1500 Post Road, near the intersection of Post Road and Whitney Road, Anchorage, Alaska. The site is in the industrial area of Ship Creek. It is bounded by Post Road to the north and west and by the Alaska Railroad tracks and Ship Creek on the south. The property originally was the site of mechanical contracting business. Two USTs were present on-site, a 2,000-gallon gasoline tank installed in 1982/1983 and a 2,000-gallon waste oil tank of unknown installation date. Both USTs were reportedly taken out of service (last used) in December 1991. In September and October 1992, the two USTs were excavated and removed. During 1992 and 1993 site activities, approximately 77 tons of petroleum contaminated soils were excavated, stockpiled on-site and in 1993 transported to the Anchorage Regional Landfill. Additionally, a limited site assessment was performed during the 1992 removal activities. Impacted soil and groundwater were identified. A limited release investigation was performed in 1995. Six groundwater monitoring wells were installed and sampled. Annual groundwater monitoring was performed in 1997 and 1998. A horizontal well intended for remediation was installed in June 1997. The remediation system was not completed. The trustee for the bankruptcy trust informed the DEC in 2002 that the property has been sold. Although the facility may be eligible to receive grants under the current the State of Alaska Financial Assistance Program to fund cleanup activities, none have been accepted to date.
Public Health and Environmental Concerns
The contaminants of concern (COCs) are primarily petroleum; gasoline and gasoline components (BTEX). Additionally, chlorinated solvents have been identified. Petroleum contaminated soil and groundwater remain on property.
DEC completed review of the Remedial Investigation Report, dated 6/21/0, prepared by the Alaska Railroad Corporation. Currently contamination containing benzene, Diesel Range Organics, tetrachloroethylene (PCE), and trichloroethylene (TCE) remain on site. Any remaining contamination on site appears to be just above DEC’s most stringent cleanup levels. Furthermore, contamination is not migrating toward Ship Creek.
DEC determined on January 8, 2008, that no further remedial action will be required at this site subject to the following conditions: A notice of contamination is recorded in the DEC database, any proposal to transport soil requires DEC approval, and groundwater wells may not be installed on site without approval from DEC.
