Current Site Status
The Stauffer Chemical Co. (LeMoyne Plant) site includes the area where the Stauffer Chemical Company (Stauffer) began operating a chemical manufacturing facility in the 1950s. EPA placed the site on the National Priorities List (NPL) in 1984 because of contaminated ground water, sediment and soil resulting from manufacturing operations. EPA, the Alabama Department of Environmental Management (ADEM), and Akzo Nobel and Chemtura Corporation, the site’s potentially responsible parties (PRPs), 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. A water line connects residences and businesses to the public water supply. By treating ground water and undertaking Five-Year Reviews, EPA, ADEM and the site’s PRPs continue to protect people and the environment from site contamination.
The 730-acre site is located in Axis, Mobile County, Alabama, approximately 25 miles north of Mobile. The Stauffer Chemical Co. (Cold Creek Plant) Superfund site is located next to the site. The site’s surroundings are primarily industrial land uses. The nearest residential property is a few miles from the site.
Stauffer began manufacturing hazardous chemicals at the site in the 1950s. From 1965 to 1974, operations included discharging waste into an unlined landfill on the eastern side of the site. In 1975, the landfill closed. From 1965 to 1979, Stauffer leased a small area on the western end of the site to Halby Chemical Company for manufacturing operations. Halby Chemical Company discharged waste into a pond on the southwest portion of the site next to the Norfolk Southern rail line and eventually into Cold Creek Swamp next to the site. In 1984, EPA listed the site on the NPL. Akzo Nobel currently owns the site property and manufactures chemicals at the site.
Site investigations found contamination in ground water, sediment and soil that could potentially harm people in the area. Contamination resulted from waste handling practices at the site. Contaminants of concern include thiocarbamates, carbon tetrachloride, carbon disulfide, thiocyanate and mercury.
Contamination affected ground water beneath the site and the neighboring Stauffer Chemical (Cold Creek) site. Contamination also affected sediments and fish in the swamp. The Alabama Department of Public Health placed a fish advisory on Cold Creek Swamp from Cold Creek and the Mobile River west through the swamp. The fish advisory states that people should not eat fish caught in this area.
Investigation and Cleanup Responsibility / Oversight
Akzo Nobel and Chemtura Corporation, the site’s PRPs, lead site investigation and cleanup activities with oversight provided by EPA and ADEM.
Site Cleanup Plan
Site investigations and cleanup activities have focused on three areas, which EPA refers to as operable units, or OUs. These areas include OU-1: contaminated ground water; OU-2: source contamination; and OU-3: contaminated surface water and sediment in Cold Creek Swamp. OU-1 and OU-3 include areas of the site and the Stauffer Chemical Co. (Cold Creek) Superfund site.
In 1989, EPA issued a cleanup plan (a Record of Decision, or ROD) for OU-1. The plan included the following activities:
- Continuing use of the existing ground water treatment system.
- Installing additional ground water extraction wells.
- Modifying the ground water treatment system.
- Monitoring ground water and the ground water treatment system.
In 1999, EPA issued a cleanup plan (a ROD) for OU-2. The plan included the following activities:
- Constructing a system to speed up the movement of contaminants from subsurface soil into ground water.
- Treating ground water contamination with a ground water treatment system.
- Placing an institutional control on the site property.
In 1993, EPA issued a cleanup plan (a ROD) for OU-3. The plan included the following activities:
- Digging up contaminated soil from the Transition Zone area of Cold Creek Swamp.
- Disposing of and capping the soil in the Upper Arm Swamp Zone.
In 2010, EPA issued an interim amended cleanup plan (a ROD), which made changes to the cleanup approach selected in 1993. The new cleanup plan included the following activities:
- Building a cap over contaminated soil and sediment in the Upper Arm Swamp Zone instead of digging up contamination in the Transition Zone.
- Monitoring Cold Creek Swamp to evaluate the effectiveness of the cleanup activities.
In 1995, the site’s PRPs completed the design for a modification to the ground water treatment system and identified contamination in Cold Creek Swamp. PRPs completed the cleanup plan design for OU-2 in 1999.
The site’s third Five-Year Review, completed in 2011, found that the cleanup for OU-1 remains protective of human health and the environment and the cleanup for OU-2 will be protective of human health and the environment following completion. Parties have not implemented the cleanup for OU-3 and it was not included in the Five-Year Review.
EPA continues to negotiate with site PRPs for the cleanup of OU-2. The PRPs continue to fund site cleanup, monitoring and oversight activities for OU-1 and OU-3.
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. EPA held a 30-day public comment period where the Agency accepted input on the proposed cleanup plan to amend the 1993 OU-3 cleanup plan (ROD).
The site’s ground water treatment system for OU-1 will continue to operate and treat ground water until all contaminants of concern meet cleanup goals.
The PRPs plan to begin cleanup activities for OU-3.
EPA completed the last Five-Year Review in 2011 and plans to complete the next Five-Year Review in 2016.
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.
