CONVENT, La. (AP) - The federal Environmental Protection Agency is ordering the Louisiana Department of Environmental Quality to tighten the air pollution permit granted to Nucor Corp.'s St. James Parish plant.
NOLA.com ' The Times-Picayune reports that the EPA concludes the new pig iron and direct reduced iron manufacturing plant violates parts of the federal Clean Air Act.
The objections were published Friday in the Federal Register.
The EPA has ordered Louisiana to require additional controls to block release of toxic pollutants from the plant's coke ovens, including arsenic, benzene, lead compounds and cobalt compounds. Coal is heated into coke, which is then used in ovens to convert iron ore into iron.
Nucor began in Convent in December. The complex could grow to a $3.4 billion investment employing as many as 1,250.
