Proposal to Strengthen Standards for Synthetic Organic Chemical Plants and Polymers and Resins Plants

On April 6, 2023, the U.S. Environmental Protection Agency (EPA) announced a proposal to significantly reduce emissions of toxic and other harmful air pollution from chemical plants, including the highly toxic chemicals ethylene oxide (EtO) and chloroprene. The reductions would dramatically reduce the number of people with elevated air toxics-related cancer risks in communities surrounding the plants that use those two chemicals, especially communities historically overburdened by air toxics pollution, and cut more than 6,000 tons of toxic air pollution a year.
