[EPA-HQ-SFUND-1983-0002; FRL-9213-9]


National Oil and Hazardous Substances Pollution Contingency Plan; 
National Priorities List: Partial Deletion of the Denver Radium 
Superfund Site

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule, extension of public comment period.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) Region 8 issued a 
Notice of Intent to Delete portions of the Denver Radium Superfund Site 
from the National Priorities List (NPL) on September 9, 2010 (75 FR 
54779). The portions proposed for deletion are each of the 11 operable 
units at the Denver Radium Site, located in the City and County of 
Denver, Colorado. Groundwater contamination associated with Operable 
Unit 8 will remain on the NPL. To ensure that everyone has an 
opportunity to comment, EPA is extending the public comment period 
through November 1, 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, other than operation, maintenance and five-year 
reviews have been completed.
    This rationale for deleting the 11 operable units of the Denver 
Radium Superfund Site has not changed. The Federal Register notice for 
the proposed deletion (75 FR 54779) discusses this rationale in detail.

DATES: Comments concerning the proposed partial deletion may be 
submitted to EPA on or before November 5, 2010.
