          - 40 CFR Part 300
          - [EPA-HQ-SFUND-1983-0002; FRL-9198-7]

# AGENCY:

Environmental Protection Agency.

# ACTION:

Proposed rule.

# SUMMARY:

The Environmental Protection Agency (EPA) Region 8 is issuing a Notice of Intent to Delete each of the 11 operable units, with the exception of groundwater contamination associated with Operable Unit 8, of the Denver Radium Superfund Site (Site), located in the City and County of Denver, Colorado, from the National Priorities List (NPL) and requests public comments on this proposed action. Groundwater associated with Operable Unit 8 will remain on the NPL. 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, have determined that all appropriate response actions at these identified parcels under CERCLA, other than operations and maintenance and five-year reviews, have been completed. However, this deletion does not preclude future actions under Superfund.

This partial deletion pertains to each of the 11 operable units of the Denver Radium Superfund Site. Groundwater contamination associated with Operable Unit 8 will remain on the NPL and is not being considered for deletion at this time.

# SUPPLEMENTARY INFORMATION:

                    In the “Rules and Regulations” Section of today's                     **Federal Register,**                     we are publishing a direct final Notice of Partial Deletion for each of the 11 operable units, with the exception of groundwater contamination associated with Operable Unit 8, of the Denver Radium Superfund Site without prior Notice of Intent for Partial Deletion because EPA views this as a noncontroversial revision and anticipates no adverse comment. We have explained our reasons for this partial deletion in the preamble to the direct final Notice of Partial Deletion, and those reasons are incorporated herein. If we receive no adverse comment(s) on this partial deletion action, we will not take further action on this Notice of Intent for Partial Deletion. If we receive adverse comment(s), we will withdraw the direct final Notice of Partial Deletion, and it will not take effect. We will, as appropriate, address all public comments in a subsequent final Notice of Partial Deletion based on this Notice of Intent for Partial Deletion. We will not institute a second comment period on this Notice of Intent for Partial Deletion. Any parties interested in commenting must do so at this time.                

                    For additional information, see the direct final Notice of Partial Deletion which is located in the Rules section of this                     **Federal Register.**
