Current Site Status
The Stauffer Chemical Co. (Cold Creek Plant) site includes the area where Stauffer Chemical Company (Stauffer) operated an agricultural chemical manufacturing facility beginning in 1966. 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 Syngenta Crop Protection, Inc., 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. 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 PRP continue to protect people and the environment from site contamination.
The 220-acre site is located in Bucks, Mobile County, Alabama, approximately 25 miles north of Mobile. The Stauffer Chemical Co. (LeMoyne 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 manufactured agricultural chemicals at the site from 1966 until 2008. Operations discharged wastewater into clay-lined ponds and the nearby 650-acre Cold Creek Swamp until approximately 1975. In 1984, EPA listed the site on the NPL. Stauffer sold the site to ICI Americas, Inc. (now Syngenta Crop Protection, Inc.). Syngenta Crop Protection, Inc. currently owns the vacant 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 (LeMoyne Plant) site. Contamination also affected sediments and fish in Cold Creek Swamp. The Alabama Department of Public Health placed a fish advisory on the Cold Creek Swamp from Cold Creek and the Mobile River west through the swamp. The advisory states that people should not eat fish caught in this area.
Investigation and Cleanup Responsibility / Oversight
Syngenta Crop Protection, Inc., the site PRP, leads 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. (LeMoyne Plant) 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 1995, EPA issued a cleanup plan (a ROD) for OU-2. The plan included the following activities:
- Undertaking no further action at the Cold Creek LeCreek Waste Treatment Pond.
- Maintaining the cap for the Cold Creek North Landfill and South Landfill.
- Continuing ground water monitoring at the Cold Creek North Landfill and South Landfill.
- Using living organisms to break down contaminants in soil.
- Filling and capping the Old Neutralization Pond.
In 1999, EPA issued an Explanation of Significant Differences (ESD) that expanded the cleanup approach for OU-2. Additional cleanup activities included digging up and disposing of contaminated soils in the Old Neutralization Pond off site.
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 the 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 PRP completed the design for a modification to the ground water treatment system and identified source contamination contributing to ground water contamination and contamination in Cold Creek Swamp. The contaminated soil. The PRP completed demolition of the manufacturing facility in 2010.
The site’s third Five-Year Review, completed in 2011, found that the cleanup remains protective of human health and the environment.
EPA negotiated legal agreements with the site PRP to investigate and clean up the site. The PRP continues to fund site cleanup, monitoring and oversight activities.
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 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 PRP is planning the final phase of cleanup activities for OU-2 and implementing the 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.
