A chemical plant in the heart of Louisiana’s “Cancer Alley” has put production on hold because of poor financial results.

Denka Performance Elastomer, located along the Mississippi River about an hour west of New Orleans, announced Tuesday that it had experienced “extraordinary losses” and will indefinitely cease production at its plant, the only producer of chloroprene rubber, also known as neoprene, in the U.S.

The plant’s emissions of chloroprene, a likely carcinogen, have been linked to high cancer rates in the nearby Black-majority community. The plant drew national attention as an example of environmental injustice and was subject to a federal lawsuit under former President Joe Biden. The EPA under Biden also moved to tighten regulations on chloroprene emissions.

After President Donald Trump took office, the Justice Department dropped the lawsuit, describing the move as “delivering on President Trump’s promise to dismantle radical DEI (Diversity, Equity, and Inclusion) program.

Denka, a Japanese firm, said it stopped production after financial losses related to rising energy costs, supply chain disruption, severe weather, and the cost of installing new pollution controls and finding qualified staff.
