The kilns at the plant about 30 miles south of Bloomington underwent a conversion during 2003 that increased cement production, said Tim Matz, corporate environmental manager at Lehigh’s Allentown, headquarters. "We showed the EPA it was not a violation of the Clean Air Act like they thought, and they agreed to that," he said. "But they still are fining us $40,000 for the time between the first and second tests when our emissions were not in compliance. We have agreed to that to resolve the issue."
The EPA could have assessed fines of up to $27,500 per day. Matz said that in changing the process of mixing and drying the ingredients, the plant’s emissions increased but that the company then took action to get them back in line.
