What is RACER?

RACER -- or Revitalizing Auto Communities Environmental Response -- was created by a U.S. Bankruptcy Court to clean up and position for redevelopment former General Motors (GM) properties. Although the Moraine plants have been sold, RACER remains responsible for cleaning up any contamination associated with GM's operations at the plants. All of the work RACER performs to address these issues is approved and overseen by US EPA, Ohio EPA and both Ohio Department of Health and Montgomery County Department of Health.


The Motors Liquidation Co. (MLC) site covers 465 acres along Dryden, Stroop and Springboro roads in Moraine, OH and includes former manufacturing sites for Delphi Harrison Thermal Systems, the GM Truck Group Assembly Plant and the GM Powertrain Group Engine Plant. Frigidaire, a GM division, also produced appliances on the site from the late 1920s until 1979. Delphi ceased operations in 2003, and GM stopped all manufacturing in late 2008. Many of the buildings have been torn down, but the giant 4 ½ million-square-feet assembly plant remains. In 2001 the DMAX Engine Plant was built at 3100 Dryden Road on the northwest corner of the complex.

MLC was formed out of the 2009 GM bankruptcy and took over most of GM's nonproductive assets. MLC was given a budget to clean up the automaker's former properties and then sell or dispose of the land for redevelopment or reuse.

EPA and state partner Ohio EPA have been involved with the site since the environmental regulators issued the first of many legal orders in 1991.
