Site Background
The Kassauf-Kimerling Superfund site (also referred to as 58th Street Landfill) is located in Hillsborough County, just north of Columbus Drive on the east side of 58th Street in Tampa, Florida. The site is less than one acre – about 60 feet wide by 700 feet long – and lies just east of 58th Street and west of a marsh separating the site from the Peninsular Fisheries. A canal was cut through the landfill in the late 1970s and connects a marsh located west of 58th Street to the marsh located just east of the site.
The landfill material consists of rubber and plastic lead-acid battery casings covered by a thin layer of sand. Battery casings were disposed at the site in the fall of 1978 after peat deposits were excavated. Based on aerial photography review, 58th Street Landfill was constructed across the marsh sometime prior to 1976. The site is currently vacant and access is restricted by fencing and locked gates.
Threats and Contaminants
EPA directed a Remedial Investigation from 1985 to 1988, which identified contamination in soils and surficial ground water at the landfill as well as in surface water and sediments in the adjacent marsh. EPA conducted an additional study focusing on surface water and sediments in the marsh.
Contaminants of Concern for the site are those contaminants commonly associated with car battery materials that may pose a threat to human health and the environment. These include arsenic, lead, and cadmium.Site Cleanup Plan
The cleanup plan for the site covered two operable units (OUs): OU-1 (the landfill area) and OU-2 (the marsh/wetland).
The Record of Decision (ROD) for OU-1was issued in 1989. The cleanup approach involved containing the landfill wastes and contaminated underlying soils. It included excavation, treatment by solidification/chemical fixation and disposal on site. Specific components of the cleanup approach included:
- Excavation of fill material, as determined by the presence of battery fragments, plus any underlying soils exceeding extraction procedure toxicity criteria for Resource Conservation and Recovery Act (RCRA) hazardous waste.
- Treatment of excavated fill material and soil to meet at a minimum RCRA criteria.
- Disposal of the treated soil in the landfill area.
The Record of Decision (ROD) for OU-2 was issued in 1990. It focused on mitigation of the wetlands (marsh) adjacent to the landfill at the site. Major components of the cleanup approach included:
- Excavation and treatment by solidification of contaminated marsh sediments within 20 feet of the landfill.
- Excavation and treatment by solidification of contaminated marsh sediments in the canal east of the site extending 150 feet from the landfill.
- Allowing the remainder of the marsh sediments to remain in place without treatment, and altering the marsh such that it remains flooded year round.
- Mitigation (restoring, establishing, or enhancing a new or existing wetlands/marsh) to compensate for the marsh that was adversely impacted.
The 1990 ROD did not specify any particular requirements for the mitigation, but did require that the mitigation work be performed in the adjacent marsh, as opposed to off-site mitigation. However, the area of the marsh impacted by contamination from the landfill was owned by a private citizen. In an effort to carry out its obligations, the potentially responsible party (PRP) offered to buy the private citizen's property. However, the citizen refused to sell it on any reasonable terms.
The McKay Bay Nature Park was initially proposed as an alternative location for the wetlands mitigation project in a 1994 Explanation of Significant Differences (ESD); however, EPA and the State determined that McKay Bay was an unacceptable alternate location for implementation of the wetlands mitigation because McKay Bay was found to be contaminated. In 1997, EPA issued another ESD, which changed the location of the wetlands mitigation from McKay Bay to Mobbly Bay.
The Mobbly Bay project is located in Northern Tampa Bay (Old Tampa Bay) within approximately 15 acres of property owned by the City of Olds Mar (about 14 acres) and Panelist County, which are currently used as an easement by the Florida Power Corporation which lies to the south. The project site was composed of several man-made open water ponds (borrow pits) that were excavated several decades ago to fill adjacent lands for urban development.
Cleanup Progress
Cleanup actions intended for OU-1 and OU-2 were completed in 1994. Routine ground water monitoring at the site began in 1998 and is still ongoing.
In October of 1997, an agreement was reached with the PRP to initiate construction on the Mobbly Bay wetland mitigation project. The Mobbly Bay project was developed by the Southeast Florida Water Management District under the Surface Water Improvement and Management (SWIM) Act. All on-site construction has been completed at Mobbly Bay. After site cleanup was completed and cleanup goals were reached, the site was deleted from the National Priorities List in 2000.
According to the 2004 Five-Year Review (FYR) for the site, the cleanup approaches used for OU-1 and OU-2 at the site are still effective and continue to protect human health, welfare and the environment. Data collected from the ground water monitoring wells indicate the contaminant concentrations are stable and in some wells have shown a decline. In addition, the ground water contamination does not appear to pose any current threat to the environment or to human health at present. The ground water collection system appears to be effective in containing the plume and removing contaminants. Institutional controls at the Kassouf-Kimerling Superfund site remain in place and are effective. The 2009 FYR is underway and is expected to be completed by September 2009.
Site cleanup and monitoring activities are being led primarily by PRPs, with oversight by EPA.
Enforcement Activities
In 1991, a Consent Decree for the site was entered into between the United States of America and Gulf Coast Recycling, Inc.
Community Involvement
EPA has conducted a range of community involvement activities at the Kassauf-Kimerling site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process. Outreach activities have included public notices and information meetings on cleanup progress and activities.
