Fertilizer Maker to Cut Air Emissions

Three subsidiaries of the Potash Corporation of Saskatchewan (PCS), the world’s largest fertilizer producer, will take steps to reduce harmful air emissions at eight U.S. production plants, the U.S. Environmental Protection Agency (EPA) and Department of Justice said.

The settlement resolves claims these PCS subsidiaries violated the Clean Air Act when they modified facilities in ways that released excess sulfur dioxide into surrounding communities.

The settlement requires PCS Nitrogen Fertilizer, AA Sulfuric Inc., and White Springs Agricultural Chemicals Inc. to install, upgrade and operate state-of-the-art pollution reduction measures, as well as install emissions monitors at eight sulfuric acid plants across facilities in Geismar, LA (one plant), White Springs, FL (four plants), and Aurora, NC (three plants). The three companies will spend an estimated $50 million on these measures, and will pay a $1.3 million civil penalty.

“Large industrial facilities that break the law and pollute the air will be held accountable,” said Cynthia Giles, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance. “This case will bring these companies into compliance and require additional action to cut pollution to benefit communities, especially those most vulnerable to air pollution.”

“This agreement, the largest so far in our ongoing Clean Air Act enforcement efforts against sulfuric-acid producers, will ensure cleaner air for citizens across the Southeast and will send a strong signal to the industry that noncompliance has serious consequences,” said Acting Assistant Attorney General Sam Hirsch for the Department of Justice’s Environment and Natural Resources Division.

EPA said the agreement will reduce harmful emissions by over 13,090 tons per year, which includes approximately 12,600 tons per year of sulfur dioxide, 430 tons per year of ammonia and 60 tons per year of nitrogen oxide. In the future, the companies can also retire plants to comply with the settlement.

The settlement also includes a “supplemental environmental project,” estimated to cost between $2.5 and $4 million, to protect the community around a PCS Nitrogen nitric acid plant in Geismar, LA, and requires PCS Nitrogen to install and operate equipment to reduce emissions of nitrogen oxide and ammonia. This project is part of EPA’s commitment to advancing environmental justice by reducing the disproportionate environmental impacts on communities near industrial facilities – in this instance, by reducing fine particulates that can aggravate respiratory disease.

Sulfur dioxide, the predominant pollutant emitted from sulfuric acid plants, has numerous adverse effects on human health and is a significant contributor to acid rain, smog and haze. Sulfur dioxide — along with nitrogen oxide —converts in the air to particulate matter that can cause severe respiratory and cardiovascular impacts, and premature death.
