One of the nation's largest hog producers has entered into a civil settlement to resolve charges of environmental violations.

Premium Standard Farms (PSF) and its parent company, Continental Grain Company, together comprise the second largest hog producer in the United States. The accord with the U.S. Environmental Protection Agency (EPA) and Justice Department and the Citizen's Legal Environmental Action Network resolves alleged water and air violations at company farms in northern Missouri.

The settlement calls for testing and installing wastewater treatment technologies, testing lagoons for leaks, monitoring air emissions and paying civil fines of $350,000.
