Current Status

The Murray-Ohio Dump site includes an area where two landfills operated from 1963 to 1982. EPA placed the site on the National Priorities List (NPL) in 1983 because of contaminated ground water, soil, surface water and sediment resulting from landfill operations. EPA, the Tennessee Department of Environment and Conservation (TDEC) and the Murray-Ohio Manufacturing Company, the site’s potentially responsible party (PRP), have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Since 2005, EPA has taken the lead on site activities in cooperation with TDEC. Site contamination does not currently threaten people living and working near the site. A water line connects nearby residents and businesses to the public water supply. By conducting cleanup activities, monitoring on-site seep, surface water and ground water, placing institutional controls on the site property, and undertaking Five-Year Reviews, EPA and TDEC continue to protect people and the environment from site contamination.

Site Location and Background

The 27.25-acre site is located on Glen Springs Road in Lawrence County, Tennessee, about three miles southwest of Lawrenceburg. The site includes two landfill areas covering 0.25 acres and 27 acres, respectively. The 0.25-acre area is known as the 1973 Disposal Area. The western portion of the 27-acre area is known as the Pre-1973 Disposal Area. The eastern portion of the 27-acre area is known as the Post-1973 Disposal Area. Several streams are located near the site, including the Southeast Branch, Southwest Branch and Northeast Branch, which all flow into Shoal Creek. County and city-owned landfills surround the site. The site’s broader surroundings include rural residential areas as well as forested and agricultural land.

From 1963 to 1982, the Murray-Ohio Manufacturing Company operated a landfill at the site. Operations buried paint and electroplating sludge wastes from the production process of lawn mowers, bicycles, toys and other metal products on approximately 6 acres of the site. Operations released liquid waste and sludges into open trenches on site. The City of Lawrenceburg operated a sanitary landfill on the remaining area of the site. In 1983, EPA listed the site on the NPL. Tthe site is not in use.

Threats and Contaminants

Site investigations found contamination in ground water, soil, surface water and sediment that could potentially harm people in the area. Contamination resulted from landfill operations at the site. Contaminants of concern include chromium, hexavalent chromium, and nickel .

EPA has addressed soil contamination at the site.

Ground water contamination remains within the site’s boundary. Residences and businesses nearby use the public water supply. Contamination has not affected private wells. EPA placed institutional controls on the site property and the property next to the site to prohibit well drilling and the use of ground water for drinking water purposes.

Ground water contamination affected surface water and sediment near the site. EPA considers ecological receptors at risk of coming in contact with contaminated surface water and sediment. EPA determined that people are not at risk of exposure to contaminated ground water, soil, surface water or sediment at the site.

EPA considered children’s health issues as part of the site’s risk assessment.

Investigation and Cleanup Responsibility / Oversight

EPA leads site cleanup activities in cooperation with TDEC.

The Murray-Ohio Manufacturing Company performed the site’s remedial investigation/feasibility study (RI/FS) in 1990 and cleanup activities from 1995 to 1998. In 2005, EPA assumed responsibility for site cleanup activities.

Site Cleanup Plan

In 1994, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:

In 2009, EPA issued a cleanup plan amendment (a ROD Amendment) to add cleanup activities for off-site surface water and sediment in a tributary of Shoal Creek. The amended plan included the following activities:

Summaries of site cleanup approaches are also available online in key site cleanup documents, including the ROD.

Cleanup Progress

During 1997 and 1998, the site’s PRP constructed protective covers over the landfill areas to contain the sources of ground water contamination.

EPA began monitoring and maintaining the landfill cap cover system, including mowing and seeding the area, in 2003.

EPA completed a focused feasibility study to address contamination in landfill discharge and began remedial design activities for the ROD Amendment in 2009.

The site’s third Five-Year Review, completed in 2011, found that the cleanup remains protective of human health and the environment for the short term. The Five-Year Review also recommended that, for the cleanup to be protective over the long term, repairs should be made to the cap, operation and maintenance activities should resume, and the institutional controls on the site property should be updated to limit digging or building on the landfill areas.

Summaries of cleanup activities are also available in Five-Year Reviews online.

Enforcement Activities

EPA negotiated legal agreements with the site’s PRP to investigate and clean up the site. The PRP conducted site investigations, cleanup activities, monitoring, and operation and maintenance activities until 2004.

In 2005, EPA assumed responsibility for the site’s cleanup. EPA is using federal funds for site activities.

RODs and Five-Year Reviews online provide additional information on specific legal agreements for the site.

Community Involvement

EPA has worked with the community and its state partner to develop a long-term cleanup plan for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.

EPA has conducted a range of community involvement activities to solicit community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts have included public notices, interviews and information meetings.

Future Work

EPA is conducting on-site seep, surface water and ground water monitoring.

EPA continues to conduct remedial design activities.

EPA completed the last Five-Year Review in 2011 and plans to complete the next Five-Year Review in 2016.
