INDIANAPOLIS (AP) — A federal cleanup is under way in Indianapolis at the site of a shuttered business that collected and stored used oil for decades.

The U.S. Environmental Protection Agency said Wednesday crews had begun cleaning up the 1.35-acre AA Oil Site that's been abandoned since 1993.

The Indianapolis Business Journal reports the site contains six above-ground storage tanks and a 1,800-square-foot warehouse built in 1949.

The EPA says crews will remove lead, pesticides and the industrial solvent trichloroethene from the tanks, which will be dismantled and decontaminated.

AA Oil collected oil from garages, gas stations and other businesses from the 1950s into the 1980s. That oil was shipped to its parent company in the northwest Indiana town of Westville and re-refined for use in automotive and industrial lubricating oil blends.
