# ACTION:

Final rule.

# SUMMARY:

                        The U.S. Environmental Protection Agency (EPA) Region 8 announces the deletion of the Midvale Slag Superfund Site (Site), located in Salt Lake County, Utah, from the National Priorities List (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 Utah, through the Utah Department of Environmental Quality (UDEQ), have determined that all                               ( print page 18781)                            appropriate response actions under CERCLA, other than operation, maintenance and five-year reviews of the Site, have been completed. However, this deletion does not preclude future actions under Superfund.                    

# DATES:

This action is effective April 8, 2015.

# SUPPLEMENTARY INFORMATION:

                    The site to be deleted from the NPL is: Midvale Slag Superfund Site (Site), located in Salt Lake County, Utah. A Notice of Intent to Delete for this Site was published in the                     **Federal Register**                     (80 FR 6496) on February 5, 2015.                

                    The closing date for comments on the Notice of Intent to Delete was March 9, 2015. One public comment was received. The comment requested that the Site not be deleted over concerns that water quality in the Jordan River would not be protected from the potential release of hazardous substances from the Kennecott North and Kennecott South Sites. The EPA believes the deletion action is appropriate as the remediation goals for this Site have been met and the water monitoring data shows that the Jordan River is not being adversely affected by this Site. A responsiveness summary was prepared and placed in both the docket, EPA-HQ-SFUND EPA-HQ-SFUND-1991-0006, on                     *www.regulations.gov,*                     and in the local repository listed above.                

EPA maintains the NPL as the list of sites that appear to present a significant risk to public health, welfare, or the environment. Deletion from the NPL does not preclude further remedial action. Whenever there is a significant release from a site deleted from the NPL, the deleted site may be restored to the NPL without application of the hazard ranking system. Deletion of a site from the NPL does not affect responsible party liability in the unlikely event that future conditions warrant further actions.
