DALLAS— The U.S. Environmental Protection Agency has entered into a consent agreement with Denka Performance Elastomers L.L.C. over its handling of likely carcinogenic waste at its production facility in LaPlace, La.
In a statement Dec. 28, the agency said Denka had "failed to make an appropriate hazardous waste determination" for "poly kettle strainer waste," a chloroprene waste generated from the manufacturing of polychloroprene rubber.
The EPA said it has classified chloroprene as "a likely carcinogen" and that this waste contributed to emissions of chloroprene from the plant.
During the visits, the agency said it observed Denka's process of transferring poly kettle strainer waste to an outside, open-air brine pit.
The agency said its inspectors documented "elevated chloroprene concentrations" in the air in the vicinity of the brine pit during the process.
As part of the consent agreement, beginning Jan. 31, Denka will stop placing this waste stream in its open-air brine pit.
