Site Background:
Kassauf-Kimerling Site (also referred to as 58th Street Landfill or the Site) is located in Hillsborough County, just north of Columbus Drive on the east side of 58th Street in Tampa, Florida. The site is about 60 feet wide by 700 feet long and lies just east of 58th Street and west of marsh separating the site from the Peninsular Fisheries. A canal was cut through the landfill in the late 1970's and connects a marsh located west of 58th Street to the marsh located just east of the Site. EPA directed a Remedial Investigation (RI) from September 1985 to June 1988, which included geophysical investigations, soil boring and sampling, groundwater and surface water sampling. These investigations identified contamination in soils and surficial groundwater at the landfill as well as in a surface water and sediments in the adjacent marsh. EPA conducted an additional study focusing on surface water and sediments in the marsh. The final report was completed in 1989. The major contaminant of concern at the site is lead which was a result of disposal of battery casings.

Cleanup Progress: Actual Construction Underway
EPA issued two RODs to document the cleanup remedies selected for the site. The first ROD addressing the source of the contamination in the landfill area was designated as Operable Unit 1 (OU 1) and was signed in 1989. The second ROD (OU2) was issued to address contamination in the marsh/wetland and was signed in 1990.

The 1990 Operable Unit 2 ROD required mitigation of the wetlands (marsh) adjacent to the landfill at the Kassauf-Kimerling Site. The ROD does not specify any particular requirements for the mitigation, but does 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 is owned by a private citizen. In an effort to carry out its obligations under the Consent Decree (CD), Gulf Coast Recycling (GCR) offered to buy the private citizen's property. However, the citizen refused to sell it on any reasonable terms. An alternate location for the wetlands mitigation was chosen. The McKay Bay Nature Park was initially proposed in the February of 1994 Explanation of Significant Differences; however, EPA and FDEP determined that McKay Bay was an unacceptable alternate location for implementation of the wetlands mitigation because McKay Bay was found to be contaminated.

ROD 1 is complete and ROD 2 is ongoing. In March of 1997, EPA issued an Explanation of Significant Differences, 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 is composed of several man-made open water ponds (borrow pits) that were excavated several decades ago to fill adjacent lands for urban development. The Mobbly Bay project has been developed by the Southeast Florida Water Management District under the Surface Water Improvement and Management (SWIM) Act. In October of 1997, SWIM and Gulf Coast signed an agreement to initiate construction on this mitigation project. All on-site construction has been completed at Mobbly Bay. Monitoring of the groundwater is still underway.

The site was deleted from the NPL on October 2, 2000.  The last 5 Year Review was completed in September 2004.  The next 5 Year Review is due September 2009.
