Environmental Protection Agency.
Proposed rule, reopening of public comment period.
The Environmental Protection Agency (EPA) Region 8 issued a Notice of Intent to Delete portions of the Rocky Mountain Arsenal Federal Facility (RMA) from the National Priorities List (NPL) on June 17, 2010. The portions proposed for deletion are the Central and Eastern Surface Areas of the On-Post Operable Unit (OU3) including surface media and structures (CES) and the surface media of the entire Off-Post Operable Unit (OU4) (OPS). A formal request was made to extend the public comment period which is scheduled to end on July 19, 2010. In response, EPA is reopening the public comment period for an additional 30 days concluding on August 16, 2010.
The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The EPA and the State of Colorado, through the Colorado Department of Public Health and Environment (CDPHE), have determined that all appropriate response actions under CERCLA at the CES and OPS, other than operation, maintenance, and five-year reviews, have been completed.
This rationale for deleting the CES and OPS from RMA has not changed. The Federal Register notice for the proposed deletion (75 FR 34405) discusses this rationale in detail.
The comment period for the proposed rule published June 17, 2010, at 75 FR 34405, is reopened. Comments concerning the proposed partial deletion may be submitted to EPA on or before August 16, 2010.
