National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List

The U.S. Environmental Protection Agency (EPA) Region 10 announces the deletion of the surface soils at the South Tacoma Field Operable Unit of the South Tacoma Channel Superfund Site (the Site) from the National Priorities List (NPL). The NPL is defined in Appendix B of 40 CFR part 300 which is the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), which EPA promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended. This partial deletion pertains to the South Tacoma Field soils portion of the Site. This partial deletion does not pertain to the groundwater portion of the South Tacoma Field or to other operable units of the South Tacoma Channel Site. EPA and the State of Washington have determined that the Site poses no significant threat to public health or the environment. All appropriate response actions for soils have been implemented, therefore, no further remedial measures pursuant to CERCLA are appropriate. Partial deletion of STF soils from the NPL will not affect the status of STF soils on any Washington Department of Ecology (Ecology) lists and does not preclude Ecology from conducting future investigations or requiring response under State law on any portion of the Site.
