The National Priorities List for Uncontrolled Hazardous Waste Sites; Listing and Deletion Policy for Federal Facilities

The Environmental Protection Agency (EPA) is announcing two interim final policy revisions relating to the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), 40 CFR part 300, which was promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) (amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA)). CERCLA requires that the NCP include a list of national priorities among the known or threatened releases of hazardous substances, pollutants, or contaminants throughout the United States, and that the list be revised at least annually. The National Priorities List (NPL), which is Appendix B of 40 CFR part 300, constitutes this list. This document announces an interim final revision to the Agency's policy on placing Federal facility sites on the NPL. For those Federal facility sites already on the NPL, this document describes an interim final policy revision for deleting such sites from the NPL. The interim final policy revisions apply to Federal facility sites that are RCRA- regulated facilities engaged in treatment, storage, or disposal of hazardous waste (``TSDs'' under the RCRA program). EPA requests public comments on these interim final policy revisions.
