Basis for Full Site Deletion</FP> </EXTRACT> <HD SOURCE="HD1">I. Introduction</HD> EPA is issuing a proposed rule to delete one site from the NPL and requests public comments on this proposed action. EPA will accept comments on the proposal to delete the site for thirty (30) days after publication of this document in the <E T="04">Federal Register</E> . The NPL constitutes Appendix B of 40 CFR part 300 which is the NCP, which EPA created under section 105 of the CERCLA statute of 1980, as amended. EPA maintains the NPL as those sites that appear to present a significant risk to public health, welfare, or the environment. Sites on the NPL may be the subject of remedial actions financed by the Hazardous Substance Superfund (Fund). As described in 40 CFR 300.425(e)(3) of the NCP, a site deleted from the NPL remains eligible for Fund-financed remedial action if future conditions warrant such actions. Section II. of this document explains the criteria for deleting sites from the NPL. Section III. of this document discusses procedures that EPA is using for this action. Section IV. of this document discusses the site proposed for deletion and demonstrates how it meets the deletion criteria, including reference documents with the rationale and data principally relied upon by the EPA to determine that the Superfund response is complete. <HD SOURCE="HD1">II. NPL Deletion Criteria</HD> The NCP establishes the criteria that EPA uses to delete sites from the NPL. In accordance with 40 CFR 300.425(e), sites may be deleted from the NPL where no further response is appropriate. In making such a determination pursuant to 40 CFR 300.425(e), EPA will consider, in consultation with the State, whether any of the following criteria have been met: i. Responsible parties or other persons have implemented all appropriate response actions required; ii. All appropriate Fund-financed response under CERCLA has been implemented, and no further response action by responsible parties is appropriate; or iii. The remedial investigation has shown that the release poses no significant threat to public health or the environment and, therefore, the taking of remedial measures is not appropriate. Pursuant to CERCLA section 121(c) and the NCP, EPA conducts five-year reviews to ensure the continued protectiveness of remedial actions where hazardous substances, pollutants, or contaminants remain at a site above levels that allow for unlimited use and unrestricted exposure. EPA conducts such five-year reviews even if a site is deleted from the NPL. EPA may initiate further action to ensure continued protectiveness at a deleted site if new information becomes available that indicates it is appropriate. As described in 40 CFR 300.425(e)(3), whenever there is a significant release from ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 16k characters.
