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.

Site Location and Background

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.

Threats and Contaminants

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 tetrachloridecarbon 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.

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:

In 1995, EPA issued a cleanup plan (a ROD) for OU-2. The plan included the following activities:

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:

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:

Summaries of site cleanup approaches are also available online in key site cleanup documents, including the RODs and Five-Year Reviews.

Cleanup Progress

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.

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

Enforcement Activities

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.

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 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).

Future Work

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.
