Site Description

The Portland Cement site is 71 acres of land near 1000 South Redwood Road in Salt Lake City, Utah. The site is in a commercial and industrial area bordered by a few homes and agricultural land.

Cleanup activities at the site in Salt Lake City are complete. About 825,000 cubic yards of cement kiln dust and contaminated soil were removed from the site, and the area was covered with clean soil and seeded. Long-term groundwater monitoring is the only remaining cleanup activity.

The Environmental Protection Agency (EPA) placed the site on the Superfund National Priorities List (NPL) in June 1986.

Site Risk

Between 1963 and 1983, approximately 500,000 cubic yards of cement kiln dust (CKD) were collected from the Portland Cement Plant in Salt Lake City and deposited as fill material at the site. CKD contains several heavy metals, including arsenic, lead, chromium, cadmium and molybdenum. The western area of the site contained kiln dust mixed with, and covered by, soil and demolition debris. A few hundred tons of chromium bearing bricks from the plant kiln also had been discarded at the site.

Cleanup Progress

Approximately 825,000 tons of CKD and contaminated soil were excavated and removed off site for proper disposal. Chromium-bearing bricks were removed and treated for disposal. The site was backfilled with clean soil, regraded and seeded.

The final phase of the cleanup, which deals with contaminated groundwater beneath the site, is essentially complete. The State of Utah and EPA have agreed on the use of monitored natural attenuation as the most appropriate method for addressing the groundwater contamination. Groundwater contamination is effectively contained within the site boundaries and poses little risk to public health or the environment.

Over time, the contaminants will be harmlessly flushed from the site by natural processes. Long-term monitoring and administrative restrictions on the use of site groundwater will ensure that public health and the environment are protected until the ground water is clean. A Record of Decision for implementing the groundwater plan was signed in August 1998, making the site eligible for the Construction Completion list.

Monitoring began in spring 1999, and reviews will be conducted every five years. The first five-year review was completed in May 2002, and the current (2007) five-year review is posted in Site Documents below. The site will remain on the NPL until the groundwater is clean. The site is now considered to have valuable reuse potential.

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

Early in the cleanup, the Utah Department of Environmental Quality organized a citizens' committee to keep the public informed and involved in all site activities. Lone Star Industries, one of the potentially responsible parties, conducted the remedial investigation and feasibility study for a portion of the site, under an agreement with the state.

EPA prepares an annual update of the five-year review (see link below) to inform the public of site conditions. Public comment will be solicited for the next five-year review. Public comments can be sent to the EPA Community Involvement Coordinator listed below in Contacts.
