PUBLIC NOTICE of COMPLETION
Five-Year Review for the
Murray Smelter Superfund Site
Salt Lake County, Utah

Summary: Fifth Five-Year Review Completed

The Utah Department of Environmental Quality, Division of Environmental Response and Remediation
(UDEQ/DERR), and the U.S. Environmental Protection Agency (EPA), Region 8, have completed the fifth
Five-Year Review for the Murray Smelter Superfund Site. Five-Year Reviews are required by the
Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) when hazardous
substances remain on site above levels that permit unrestricted use and unlimited exposure. Five-Year
Reviews are conducted to evaluate the site remedy and to determine whether site conditions remain
protective of human health and the environment.

Review Summary and Protectiveness Statement: The review of documents and results of the Site
Inspection indicates that the remedies at the on-facility and off-facility areas are functioning as intended
by the Record of Decision (ROD). As the off-facility area is not protected from development under the
Site soils ordinance, it was recommended the off-facility area be evaluated to determine whether
additional institutional controls are required.

A protectiveness determination of the remedy at the Murray Smelter Superfund Site cannot be made at
this time until further information is obtained. Further information will be needed by applying the 2024
Updated Soil Lead Guidance for CERCLA sites and RCRA Corrective Action Facilities. The lower guidance
screening levels will be used to determine whether further investigation and additional response actions
are necessary for the remedy to remain protective. It is expected these steps could take approximately
five years to complete after which a protectiveness determination will be made. This Five-Year Review
Report was signed August 14, 2024 and the next Five-Year Review is required five years from the
completion date.
