More than 200 chemical plants nationwide will be required to reduce toxic emissions that are likely to cause cancer under a new rule issued Tuesday by the Environmental Protection Agency.

Areas that will benefit from the new rule include majority-Black neighborhoods outside New Orleans that EPA Administrator Michael Regan visited as part of his 2021 Journey to Justice tour. The rule will significantly reduce emissions of chloroprene and other harmful pollutants at the Denka Performance Elastomer facility in LaPlace, Louisiana, the largest source of chloroprene emissions in the country, Regan said.
