Firestone Polymers LLC (Firestone) has agreed to resolve alleged violations of the Clean Air Act and several other federal and state environmental laws at the company’s synthetic rubber manufacturing facility in Sulfur, Louisiana. The company will also pay a total of $3.35 million in civil penalties.
The settlement requires several actions from Firestone, including meeting emissions limits, operation and maintenance requirements, equipment controls, limiting hazardous air pollutants from facility dryers, conducting inspections of heat exchangers, installing controls and monitors on covered flares, and installing flaring instrumentation and monitoring systems. After being notified of the violations but prior to the consent decree being lodged, Firestone took other compliance measures, including installing and operating a regenerative thermal oxidizer system to receive waste gases from dryers, reducing n-hexane solvent concentrations and inspecting and testing heat exchangers.
“This settlement will ensure cleaner air for the citizens of Louisiana and the communities near Firestone’s plant,” said Assistant Attorney General Todd Kim of the Justice Department’s Environment and Natural Resources Division. “It also enforces the company’s obligation to inform local communities of potential chemical hazards to aid state and local efforts to control accidental releases.”
