The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice announced Terra Industries Inc., one of the nation's largest producers of nitric acid and nitrogen fertilizers, has agreed to pay $625,000 in civil penalties to settle alleged violations of the federal Clean Air Act at nine of its plants in Iowa, Mississippi and Oklahoma. As part of the settlement, Terra will also spend an estimated $17 million to install and implement new controls and technologies that are expected to reduce harmful nitrogen oxide emissions at its facilities by at least 1,200 tons per year.

"Illegal air pollution from the production of nitric acid can leave the public vulnerable to long-term health problems such as respiratory illness and asthma," said Cynthia Giles, assistant administrator for EPA's Office of Enforcement and Compliance Assurance. "Bringing Terra into compliance with the Clean Air Act will protect the public health of communities across Iowa, Mississippi, and Oklahoma."
