Site Description

Rose Park Sludge Pit is a two-acre area in a Salt Lake City park, where local oil refineries disposed of their petroleum wastes from the 1920s until 1957.

EPA published a Notice of Intent to Delete the site from the National Priorities List (NPL) in 1992, and asked the public to comment on the proposed deletion. The site was deleted from the NPL on June 30, 2003. Current operation and maintenance (O&M) activities being conducted by Amoco include monitoring of groundwater and the clay cap. The most recent (fourth) five-year review was completed in September 2007.

Site Risk

Refinery sludges are very acidic and contain polycyclic aromatic hydrocarbons (PAHs) and sulfur dioxide. Site health risks included the potential for burns to people and animals that came in contact with the sludge or breathed gases from the pit. There was also the potential for groundwater contamination from the unlined sludge pit.

Media Affected Contaminants Source of Contamination
soil, solid waste, groundwater acidic refinery sludges with polycyclic aromatic hydrocarbons (PAHs) and sulfur dioxide petroleum wastes disposed of from refinery

Cleanup Progress

The following cleanup activities were completed in 1985 by the potentially responsible party (Amoco Oil Company):

  • Construction of a slurry wall around the pit to isolate the wastes and prevent groundwater contamination.
  • Installation of a clay cap on top of the pit to prevent the wastes from coming in contact with park visitors, and to keep water from seeping through the pit and contaminating groundwater.
  • For additional protection, traffic barriers were placed around the perimeter of the cap to prevent damage.
  • Installation of several groundwater wells to monitor the ongoing effectiveness of the slurry wall.

Community Involvement

Community involvement plays an important role in the Superfund process. EPA uses a number of different tools and resources to promote effective, on-going, meaningful community involvement. The goals of the Superfund community involvement program are to:

  • Keep communities affected by sites informed throughout the cleanup process
  • Provide opportunities for communities to comment and offer their input about site cleanup plans
  • Facilitate the resolution of community issues tied to a site

Community comment was solicited for the most recent (fourth) five-year review, completed in September 2007.
