Portland Cement (Kiln Dust #2 & #3)
|
Site Type: Completed NPL City: Salt Lake City County: Salt Lake Street Address: 100 S. Redwood Road Zip Code: 84116 EPA ID#: UTD980718670 Site ID#: 0800690 Site Aliases: Lone Star Industries, Portland Cement (Kiln Dist. 2 & 3), Portland Cement Debris Congressional District(s): 03 |
Site Description
The Portland Cement Site is 71 acres of land near 1000 South Redwood Road in Salt Lake City. The site is in a commercial and industrial area bordered by a few homes and agricultural land.
Cleanup activities at the Portland Cement 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.
| Media Affected | Contaminants | Source of Contamination |
| Soil, air, groundwater, debris | Arsenic, lead, chromium, cadmium, molybdenum, chromium | Kiln dust from Portland Cement facility was used as fill |
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 next five-year review will be completed in 2012. The first Five-Year Review was completed in May 2002, and the current (2007) Five-Year Review is posted in the Site Documents section. The site will remain on the NPL until the groundwater is clean. The site is now considered to have valuable reuse potential.
Community Involvement
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 scheduled for completion by June 2007. Public comments can be sent to the EPA Community Involvement Coordinator listed below in Contacts.
