HWY 60/.5 MI E OF DOVER RD

The 9.5-acre site is located in a rural area south of Florida State Road 60 in Hillsborough County, Florida, 15 miles southeast of downtown Tampa. The nearest communities include Brandon, several miles west of the site, and Dover, several miles north of the site. The site is a former liquid waste disposal facility wholly contained within a larger, 1,700-acre former mining area. The site is currently a fenced open field. The surrounding phosphate mine is also fenced. Mining for phosphate ore took place on site from the 1930s through the 1950s. Starting in late 1973, Hillsborough County leased a small portion of the site property and operated a liquid waste disposal facility until 1981. The facility accepted approximately 16 million gallons of liquid waste, including sludge, grease trappings and cutting oil for disposal. In 1989, EPA listed the site on the NPL. The property owner recently sold the site to an investment group that expects to build an alternative energy park on the site. The facility will convert algae into fuel.
