The Environmental Protection Agency (EPA), the Justice Department, and the Louisiana Department of Environmental Quality (LDEQ) announced a settlement with PCS Nitrogen Fertilizer, L.P. (PCS Nitrogen), to remedy hazardous waste issues at its former fertilizer manufacturing facility in Geismar, Louisiana.
This settlement resolves alleged violations of the Resource Conservation and Recovery Act (RCRA) at the facility, including that PCS Nitrogen failed to properly identify and manage certain waste streams as hazardous wastes. These corrosive (acidic) hazardous wastes were illegally mixed with process wastewater and phosphogypsum from phosphoric acid production. The resulting mixture of wastes was disposed of in surface impoundments.
The settlement requires PCS Nitrogen to treat over 1 billion pounds of acidic hazardous process wastewater over the next several years. The acidic hazardous process wastewaters will be contained in the phosphogypsum stack system and then treated in the newly constructed water treatment plant. The settlement also regulates the long-term closure of PCS Nitrogen’s phosphogypsum stacks and surface impoundments for over 50 years and requires PCS Nitrogen to ensure that financial resources will be available for environmentally sound closure of the facility.
PCS Nitrogen will provide over $84 million of financial assurance to secure the full cost of closure and pay a civil penalty of $1,510,023.
