Land use <br /> in the area is predominately commercial and residential, and several auto salvage and repair <br /> yards are located at, or adjacent to, the site. The site contains part of a wetlands area with <br /> several small recreational lakes in the vicinity. The site overlies three aquifers, one of <br /> which supplies the surrounding community with drinking water. Between 1954 and 1981, <br /> multiple waste storage and disposal activities occurred on several properties within the site <br /> boundaries. Source areas include a drum storage area, waste storage area, and waste <br /> burning area. During the 1960's and 1970's, solid and liquid chemical waste dumping and <br /> open pit burning of solvents occurred. Investigations showed that drum storage and <br /> chemical waste disposal sites were partially obscured by both auto salvage operations and <br /> an estimated 3 million waste tires. In 1976,citizen complaints of well contamination <br /> prompted the state to investigate the site and issue violations for improper chemical waste <br /> storage, and in 1980, for improper disposal of industrial waste. Waste processing was <br /> discontinued in 1977, and waste acceptance ceased in 1978. In 1981, the contents of <br /> approximately 700 drums were disposed of by mixing them with waste oil and using the <br /> mixture as fuel; then, in 1988 and 1989, two tire fires occurred onsite. EPA investigations <br /> determined that soil and ground water contamination had resulted from contact with <br /> leaking drums,electrical transformers, and/or salvaged automobiles. A 1988 ROD <br /> previously addressed the contaminated ground water onsite as OUL This ROD addresses <br /> the contaminated onsite soil as OU2. The primary contaminants of concern affecting the <br /> soil and debris are organics, including PAHs and PCBs; and metals, including lead. <br /> PERFORMANCE STANDARDS OR GOALS: Soil clean-up goals will meet AWQCs and <br /> Minnesota surface water quality standards. Noncarcinogenic risk will be to a HI=1. <br /> Chemicalspecific goals for soil cleanup include PAHs 2 mg/kg; PCBs 2 mg/kg; antimony <br /> 25 mg/kg; and lead 500 mg/kg. INSTITUTIONAL CONTROLS: None. <br /> [ EPA Home I OSWER Home I Superfund Home I Site Information Home I Contact Us] <br /> URL: http://www.epa.gov/superfund/oerr/impm/products/rods/r0592202.htm <br /> Last Updated: November 8, 1997 <br /> http://www.epa.gov/superfnd/oerr/impm/products/rods/r0592202.htm 8/12/98 <br />
