US Ecology Detroit South (USE-DS) is a hazardous waste storage and treatment site located at 1923 Frederick Street, in Detroit, Michigan (Site). The Michigan Department of Environment, Great Lakes, and Energy (EGLE) previously licensed the Site for the management of hazardous wastes in 2003, under the operation and ownership of US Liquids, Inc. In 2004, The Environmental Quality Company (EQ) purchased the Site from US Liquids, and US Ecology subsequently acquired EQ in 2014. Following the 2022 takeover, US Ecology and the Site are now under the operation and ownership control of Republic Services.
The Site's hazardous waste operating license issued by EGLE specifies the hazardous waste activities that USE-DS can perform at the Site. The federal Resource Conservation and Recovery Act of 1976, as amended, and the corresponding Michigan hazardous waste regulations specify how the Site must operate to protect human health and the environment. They also identify the authorities that EGLE's Materials Management Division (MMD), has in licensing and overseeing the Site's hazardous waste operations.
