Taking action on TCE

TCE by the numbers. 2 micrograms per cubic meter of TCE is the Health Based Value set by MDH. 88 facilities have been assessed. 27 use TCE in industrial processes. 61 generate TCE as a byproduct. 174,150 pounds of TCE emissions removed from facilities.

Trichloroethylene (TCE) is an industrial solvent used in manufacturing that has been linked to negative health effects. On May 16, 2020, Minnesota is the first state to have legislation that restricts most permitted uses of TCE in Minnesota. The legislation prohibits the use of TCE after June 1, 2022. 

    What businesses can do

    The Minnesota Technical Assistance Program (MnTAP) is a University of Minnesota outreach program that helps Minnesota businesses prevent pollution, use resources efficiently, and reduce energy use. The MnTAP TCE alternatives page offers information on what chemicals can be used instead of TCE, and their advantages and drawbacks. The page includes recordings of training sessions MnTAP has offered on TCE alternatives, in conjunction with the Toxics Use Reduction Institute of the University of Massachusetts.
