The Smalley-Piper site includes the area where a farm equipment manufacturing facility operated from the 1960s until 2007. EPA placed the site on the National Priorities List (NPL) in 2005 because of contaminated ground water, surface water and soil resulting from facility operations. EPA and the Tennessee Department of Environment and Conservation (TDEC) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. By designing the cleanup and completing the soil portion of the cleanup at the Site, EPA and TDEC continue to protect people and the environment from site contamination.
The 9-acre site is located in on Highway 72 in Collierville, Shelby County, Tennessee. Commercial and industrial land uses border the site. Residential areas, including single-family homes and a mobile home park, are located a quarter-mile southeast of the site.
From the 1960s until 2007, a farm equipment manufacturing facility operated at the site. In the 1960s, operations included farm tool manufacturing. In the 1970s, operations included battery casing manufacturing and treatment. Operations sent liquid wastes into an underground pipe that discharged to open retention ponds. The ponds treated the wastes and allowed the liquid to flow into surface water drainage ditches. Facility operations later abandoned the ponds and backfilled them with soil. In 2005, EPA listed the site on the NPL. Prior to shutting down in 2007, the facility applied an iron slurry to used farm tools under high temperatures to harden the new surfaces.
Currently, a self-storage facility operates on part of the site.
Site investigations found contamination in ground water, surface water and soil that could potentially harm people in the area. Contamination resulted from facility operations. Contaminants of concern include hexavalent chromium, chromium, antimony and iron.
Ground water contamination affected the Memphis Aquifer, the primary source of drinking water in the area, and poses a potential human health risk. Ground water contamination also affected two of Collierville’s public drinking water supply wells, which the town no longer uses for the drinking water supply. One private water supply well is within a one-mile radius of the site; however, it is located uphill from the site, outside the area affected by contamination, and is not known to be used for drinking water.
Investigation and Cleanup Responsibility / Oversight
The site’s potentially responsible parties (PRPs) led site investigation activities until 2006. EPA now leads site investigation and cleanup activities in cooperation with TDEC.
Site Cleanup Plan
In 2008, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:
- Digging up contaminated soil.
- Treating contaminated soils with chemicals and disposing of them off site.
- Extracting, treating and disposing of contaminated ground water on site.
- Using soil flushing on site to address contaminated soil.
- Placing institutional controls on the site property.
EPA and the site’s PRPs conducted site investigations. In 2006, the PRPs completed a draft site investigation report but were unable to continue with site investigation and cleanup activities. EPA funded remaining site investigations and selected a cleanup plan to address site contamination.
The soil cleanup was completed in September 2012. Construction of the groundwater remedy is planned to start by late 2014. The first phase of the groundwater remedy includes the construction of a water treatment system and the installation of four groundwater recovery wells at the Site. The treatment system will be able to pump and treat about 100 gallons of water per minute. Treated water will be discharged below ground at the Site through an infiltration gallery.
EPA negotiated legal agreements with the site’s PRPs to investigate the site.
Due to the PRPs’ inability to pay for cleanup activities, EPA is using federal funds for the site’s cleanup.
EPA is working 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 is conducting 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 include public notices, interviews and public meetings on cleanup activities and updates.
Construction of the groundwater remedy is planned to start by late 2014. Ground water monitoring is ongoing at the site.
EPA keeps additional site documents and information in a site information repository at the location below. EPA also posts site documents, when available, on EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office.
