The Jernigan Trucking Dump Site (the Site) is located off W. E. Fertic Drive in Seffner, Hillsborough County, Florida. The Site is in a predominantly residential area. Jernigan Trucking Dump (JTD) comprises several parcels of land owned by multiple individuals. The Site (total 178.52 acres) is divided into three portions. The northern portion of the JTD property (referred to as the Jernigan portion) consists of two parcels which together encompass 39.5 acres. The southwestern portion of the JTD property (referred to as the Lewis portion) encompasses 59.05 acres. The southeastern portion of the property (referred to as the Fertic portion) encompasses 79.97 acres. The roadbeds along the wetlands and ponds on the Fertic portion of the JTD property run east to west and consist of battery casings.
From the middle to late 1960s through the early 1980s, the original owners of the various properties used the land for mining sand and peat. The land was stripped until clay was encountered, and then debris and rubble were hauled in for use as fill material in the borrowed areas. Materials deposited included construction and demolition (C&D) debris, slag, clinkers, coal residue, kiln dust, miscellaneous trash, and lead-acid battery casings.
All former and current property owners were ordered to remove the battery casings from their properties. In the early 1990s, some or all of the battery casings were reported to be removed from the Lewis portion; however, documentation of the removal is minimal. In 2000 and 2001, battery casing removals occurred on the Jernigan portion of the property. Lead- and arsenic-contaminated soils were excavated from an unknown area of the property and stockpiled. Most of these stockpiles are still onsite. One pile was treated with a mixture of triple superphosphate and subsequently removed to an approved landfill for disposal. On November 28, 2005, EPA completed sampling on the Site. Selected areas of the property were screened for lead contamination in soil using X-Ray Fluorescence (XRF) screening. Results indicated that lead concentrations exceeded EPA Region 9 Preliminary Remedial Goals (PRGs) and Florida Soil Cleanup Target Levels (SCTLs) in 19 locations. Lead and arsenic, the primary constituents of concern, were present in all media at elevated concentrations compared to background. Elevated arsenic and lead concentrations were most frequently detected in samples collected from the Fertic portion of the Site (where a roadbed made of battery casings is located). The presence of battery casings was observed in the wetland area along the roadbed.
As a result of the sampling, EPA has determined that a removal action is necessary. The removal is a short-term cleanup intended to stabilize or clean up a site that poses an imminent and substantial threat to human health or the environment. The removal is taking place under the authority and direction of the EPA Region 4 Emergency Response and Removal Branch (ERRB).
EPA has entered into two Agreement and Order on Consents (AOCs) with Potentially Responsible Parties (PRPs). The Site is broken into two parts, the Northern Portion and the Southern Portion. The Northern Portion consists of the Jernigan parcel and the Southern Portion consists of the Fertic parcel and the southeast corner of the Lewis Parcel. The agreement has the PRPs completing the cleanup with EPA oversight.
The following activities have been accomplished at the Site for this reporting period:
• Continued to operate four TSP & PM-10 air monitors at perimeter locations of the site;
• Loaded and hauled approximately 1,715 tons of Fertic NW slag and soil from the treatment cell to the Waste Management Landfill in Okeechobee, Florida;
• Excavated approximately 775 cubic yards of impacted soil and battery casing/chips from the Fertic staging area. Material was stockpiled in the lined treatment cell near the Fertic parcel;
• Loaded and hauled approximately 3,280 tons of battery casings and soil from the Jernigan treatment cell to the Waste Management landfill in Okeechobee, Florida;
• Excavated approximately 635 cubic yards of impacted soil and battery casings/chips from the Jernigan staging area. Material was stockpiled in the lined treatment cell located near the Jernigan parcel;
• Stabilized approximately 500 cubic yards of impacted soil and battery casings/chips form the Jernigan parcel;
• Performed confirmatory sampling in completed excavation areas;
• Performed XRF sampling on the bottom and side walls of initially completed areas to guide the excavation;
• Initiated grading activities of all excavation areas in preparation for upcoming hydro-seeding activities. Grading activities include installing the 2 foot minimum thickness cover over known areas that exceed the RAL’s for arsenic and lead;
• Completed cleaning of tires encountered during excavation via dry decon. Tires were stockpiled adjacent to the relative excavation area;
• START continued to document site activities, maintain a photo log, and conduct oversight of PRPs' contractor;
• START collected 3 split samples.
The contractor will grade excavation areas throughout the site to facilitate drainage and hydroseeding activities. The excavated material will continue to be treated, tested, and disposed off. START will continue to document site activities, maintaining a photo log, conduct oversight of PRPs' contractor activities and take split samples to ensure data quality
