U.S. Environmental Protection Agency Region 5 has filed an administrative complaint against Superior Aluminum Alloys LLC for alleged violations of hazardous air-pollutant regulations at the company's secondary aluminum production plant in New Haven, Ind. EPA proposed a $120,535 penalty.
"We're alleging that Superior emitted almost three times more dioxins and furans from its thermal chip dryer than are allowed," said Region 5 Administrator Thomas V. Skinner. He said the excessive emissions were discovered during emissions tests last March.
Superior has 30 days from receipt of the complaint to file an answer and request a hearing. It may request an informal conference with EPA at any time to discuss how to resolve the allegations.
