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.
