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

The Environmental Protection Agency (EPA), Region 10, announces the deletion of the Martin Marietta Aluminum Company site from the National Priorities List (NPL). The NPL constitutes 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, as amended (CERCLA). EPA and the State of Oregon Department of Environmental Quality (DEQ) have determined that no further cleanup under CERCLA is appropriate and that the selected remedy has been protective of human health and the environment.
