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

Summary: Sixth 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 sixth Five-Year
Review for the Sharon Steel Superfund Site (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.

Report Summary and Protectiveness Statement:

This review provides the assessment of cleanup Site remedies at Operable Units (OU) 1 and 2. OU1 addresses the
former mill site, tailings pile, and groundwater. OU2 addresses contaminated soils in residential and commercial
areas. The review concludes the remedies at OU1 and OU2 are functioning as intended however additional actions
are necessary to ensure long-term protectiveness. It is recommended that the EPA and UDEQ/DERR evaluate
Institutional Controls for OU2 and if additional documentation and monitoring are necessary for the remedy to
remain protective.
Additionally, on January 17, 2024, the EPA issued “Updated Residential Soil Lead Guidance for CERCLA sites and
Resource Conservation and Recovery Act (RCRA) Corrective Action Facilities” that lowered recommended regional
screening level (RSL) for lead-contaminated soil at residential areas. The EPA and UDEQ/DERR will evaluate how
this change may impact the cleanup that was conducted at the Sharon Steel Site and determine if additional
investigation and/or cleanup is needed. The EPA and UDEQ/DERR will share information on planned activities and
results as they become available.
A protectiveness determination of the remedy at the Sharon Steel Site cannot be made at this time and is deferred
until further information is obtained. Additional response actions may be necessary for the remedy to remain
protective. It is expected that determination of the protectiveness status at the Site could take approximately 36
months to complete.
