The EPA has finalized a settlement with Denka Performance Elastomer, LLC over alleged hazardous-waste mismanagement and chloroprene-related violations at the company’s LaPlace, Louisiana facility, closing out claims brought under the Resource Conservation and Recovery Act. While RCRA settlements are not unusual on their own, this one stands out because EPA framed waste-handling deficiencies as part of a broader set of environmental and public-health risks tied to the facility’s emissions profile and its long-running scrutiny from regulators, residents, and litigants.

That matters.
