The Whitehouse Waste Oils Pits Superfund Site is located approximately 10 miles west of downtown Jacksonville in Duval County, Florida. This 7-acre Superfund Site was an abandoned waste oil sludge disposal facility located in the community of Whitehouse. From about 1956 to 1968, Allied Petro-Products, Inc. (Allied) operated the site as a repository for waste oil sludge and acidic oil refinery by-products. Wastes were dumped into seven unlined pits on site. Allied ceased operations in 1968 and filed for bankruptcy, and the City of Jacksonville (COJ), which encompasses all of Duval County, acquired the site for non-payment of taxes. Other facilities, including a transformer repair shop, are believed to have existed on site and these seven acres were used for waste disposal after Allied went bankrupt. In 1968 and again in1976, levees of certain waste pits ruptured, spilling wastes onto adjacent properties, into a tributary of McGirts Creek, and into McGirts Creek. Following the 1976 spill, the COJ partially drained the pits and capped them with clay. The Site was proposed for listing on the National Priority List (NPL) in 1981 and listed in 1983. A Record of Decision (ROD) outlining cleanup of the site was signed in 1985. Additional studies conducted between 1988 and 1991 led to an amended ROD in 1992. In 1994, an Administrative Order on Consent for new studies to better define waste materials in the pits was signed by EPA and a group of potentially responsible parties (PRPs). Treatability studies were conducted and a second amendment to the ROD was issued in 1998. EPA approved the Remedial Design in 2000 and construction activities began in 2003. As part of this work, approximately 1500 feet of a small tributary of McGirts Creek were realigned to accommodate the size of a cap and position of the confining slurry wall, part of the remedial action. The final design included features to improve the wetland habitat for plants and animals, as well as erosion control measures to protect the tributary. A preliminary close-out report was prepared by EPA for the Site in May 2006.
