An Alabama cast iron pipe manufacturer has agreed to pay $4 million to settle more than 400 violations of federal and state environmental laws, officials say.

McWane Inc., a pipe manufacturer headquartered in Birmingham, Ala., has agreed to the settlement, filed in federal court today, which covers 28 of McWane's manufacturing facilities in 14 states and also requires the company to perform environmental projects valued at $9.1 million, an Environmental Protection Agency release said Wednesday.

The environmental projects include addressing storm water contamination at numerous manufacturing locations, reducing mercury emissions at facilities in Provo, Utah, and Tyler, Texas, reducing volatile organic compound emissions in Bedford, Ind., and Anniston, Ala., and improving air quality in Coshocton, Ohio, the EPA release said.

"The additional environmental projects included in the settlement will protect children, pregnant mothers, local residents and workers from harmful pollution and are an example of securing public health and environmental benefits in addition to those achieved by compliance with our nation's environmental laws," said Cynthia Giles, assistant administrator for EPA's Office of Enforcement and Compliance Assurance

The settlement resolves civil violations over the past 10 years of the Clean Air Act, the Resource Conservation and Recovery Act and other federal environmental safety acts, the EPA said.
