Current Site Status
The Stauffer Chemical Co (Tampa) site includes the area where an agricultural chemical product formulation, packaging and distribution facility operated from 1951 until 1986. EPA placed the site on the National Priorities List (NPL) in 1996 because of contaminated ground water, sediment, soil and surface water resulting from facility operations. EPA, the Florida Department of Environmental Protection (FDEP) and 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. By treating and monitoring ground water, enforcing institutional controls and conducting required Five-Year Reviews, EPA, FDEP and the site’s PRP continue to protect people and the environment from site contamination.
Site Location and Background
The 40-acre site is located at 2009 Orient Road in an industrial area of Tampa, Florida. Most of the site is vegetated, except for the areas where support facilities were located during cleanup actions. The only facilities that remain are a maintenance building and office trailer. Site surroundings include industrial facilities to the west, the Hillsborough County Sheriff’s Office-Orient Road Jail Facility to the south, the Tampa Bypass Canal to the east, and a CSX railroad corridor to the north. A construction materials plant is located directly north of the rail corridor. The Helena Chemical Co. (Tampa Plant) Superfund site is located northwest of the site.
The site is the location of a former agricultural chemical product formulation, packaging and distribution facility. Operators packaged and distributed organochlorine and organophosphorus pesticides at the site from 1951 until 1986. The facility is now inactive. Parties demolished most of the structures used for site operations. Disposal practices at the site included the burial of wastes, pesticides and packaging materials.
In 1996, EPA listed the site on the NPL. Portions of the site along Orient Road are available for reuse.
Threats and Contaminants
Site investigations found pesticides in soil, surface water and sediment in on-site ponds and in ground water underneath the site. Contaminants of concern include chlordane, dieldrin, and DDT, DDD and DDE.
The site’s PRP continues to treat remaining on-site ground water contamination. Interceptor wells prevent ground water from spreading off site.
The PRP dug up contaminated soil, placed it in an on-site containment cell and covered the material with a cap. The PRP also drained two contaminated ponds, dug up and removed the contaminated sediment, placed liners in the ponds and then filled the ponds in with clean dirt.All areas where contamination remains on site are fenced and secured.
The PRP has placed an institutional control on the site in the form of a restrictive covenant to prohibit digging and ground water use.
Investigation and Cleanup Responsibility / Oversight
The site’s PRP, Stauffer Management Company/AstraZeneca, leads site investigation and cleanup activities, with oversight provided by EPA and FDEP. AstraZeneca owns the site; Stauffer Management Company manages site cleanup activities.
Site Cleanup Plan
In 1995, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:
- Digging up soils with contaminant levels above cleanup goals.
- Biologically treating the dug-up soils off site.
- Placing the treated soils back into the dug-up areas.
- Placing a foot of clean soil over pond sediments to reduce risk to the environment.
- Pumping and treating ground water and discharging treated ground water to the local water treatment plant.
- Restricting ground water use until ground water meets cleanup goals.
Cleanup Progress
In 1993, the site’s PRP conducted a short-term cleanup to address buried drums and debris and 3,450 cubic yards of contaminated soil. The PRP temporarily stored the contaminated soil on site and then treated it.
In 1999, the PRP began carrying out cleanup activities required in the 1995 ROD. Parties initially thought that 16,000 cubic yards of contaminated soil and 2,500 cubic yards of contaminated pond sediment required treatment. The PRP treated the contaminated soil by adding manure or wood chips to help break down organochlorine compounds such as DDT and dieldrin.
Because the initial cleanup failed to meet soil cleanup goals, EPA issued a ROD Amendment in 2006 to address the remaining untreated surface soil, sediments and below-ground soil containing dense non-aqueous phase liquid. The revised plan called for containing and capping the remaining contaminated material on site. In 2006 and 2007, the PRP carried out the revised cleanup plan.
In August 2000, the PRP installed the site’s ground water pump-and-treat system. The system continues to operate, capturing shallow ground water under the site. The system discharges the treated water to the City of Tampa’s sanitary sewer system.
The site’s second Five-Year Review, completed in 2010, found that the site’s cleanup approach continues to protect people and the environment from remaining site contamination.
Summaries of cleanup activities are also available in Five-Year Reviews online.
Enforcement Activities
EPA has 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 information on specific legal agreements for the site.
Community Involvement
EPA 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 public meetings.
Future Work
EPA completed the last Five-Year Review in 2010 and plans to complete the next Five-Year Review in 2015.
The PRP continues to operate the ground water pump-and-treat system. The PRP conducts ground water monitoring annually.
