The MRI Corporation site is an approximately 12-acre site located in Tampa, Florida. The site began operations around 1961 as a detinning/steel recycling facility. Tin cans and similar scrap metal were treated with caustic chemicals to remove the tin coating. The tin was then recovered as ingots and the remaining metal was sold for scrap. In approximately 1975, electroplating capabilities were added and in late 1979 or early 1980, a municipal solid waste recycling operation was put into service at the site. MRI Corporation ceased operations at the site in 1986.
A single concrete block warehouse and concrete foundation pads remain from the former operations. The property is covered with grasses in open areas, shrubs and trees along the northwest and southwest boundaries, and seasonally wet areas in the north and south portions. The site is bordered by industrial/commercial properties to the northwest, west, and south. Orchards and grazing pasture are located to the north and east of the site.
Site investigation and sampling activities at the site indicate that soil, sediment, and ground water at the site are contaminated with metals, primarily lead.
Site Cleanup Plan
The cleanup plan for the MRI site covers two operable units (OUs): OU-1 (soil) and OU-2 (contaminated ground water).The Record of Decision for OU-1 was issued in 1992. Major elements of the cleanup approach include:
- Excavation of metals contaminated soil and sediment.
- Solidification/stabilization of the excavated material and disposal on site.
- Capping of solidified material.
- Deed restrictions to prohibit residential use of the site and to prohibit use of shallow ground water as drinking water at the site.
- Additional ground water monitoring and evaluation as a basis for future ground water actions.
The Record of Decision for OU-2 was issued in 2008. Major elements of the cleanup approach include:
- Excavation of contaminated soils to protect ground water.
- Backfill of clean soil into areas where contaminated soil was removed.
- Containment structure (slurry or vertical barrier walls) to contain impacted shallow ground water.
- Ground water outside the containment cell will be monitored and allowed to attenuate by natural processes.
- Institutional controls through a restrictive covenant to prohibit potable ground water use on the MRI property and adjacent impacted properties and to limit future land use to uses compatible with industrial/commercial purposes.
In April 1998, MRI's parent company, Proler International, sampled ground water monitoring wells installed by EPA pursuant to an Administrative Order on Consent (AOC).
An investigation of the shallow and deeper ground water has been undertaken. The Evaluation of the Fate and Transport of Constituents of Concern in Groundwater Report has also been completed for the site.Cleanup activities are being conducted by the potentially responsible parties with EPA oversight.
In 2002, a Consent Decree (CD) was entered in between EPA and MRC Holdings, Inc., to conduct the Remedial Design and Remedial Action of the soil cleanup plan. In addition, the CD covers an investigation of the extent of contamination for the on-site and off-site shallow and deeper ground water. In addition, the settling defendants reimbursed EPA for past response costs and agreed to conduct the design of the cleanup for OU-1 and the remedial investigation/feasibility study (RI/ FS) for OU-2.
EPA has conducted a range of community involvement activities at the MRI 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, working with the local planning commission, developing fact sheets, interviews, and public meetings on cleanup activities and updates.
Implementation of cleanup activities for OUs 1 and 2 will continue.
