PCS Nitrogen has agreed to reduce air emissions from phosphoric acid production at its facility in Geismar, La., according to reports by the U.S. Environmental Protection Agency and the Louisiana Department of Environmental Quality.

The settlement resolves PCS’s alleged Clean Air Act violations at its cooling tower operations, which use scrubbers to control air emissions from its phosphoric acid processing equipment. Under the settlement, PCS will prevent the release of 15 million pounds of hydrogen fluoride and will pay a civil penalty of $198,825.

PCS has already implemented the pollution controls sought in the settlement.
