The U.S. Environmental Protection Agency and SunCoke Energy Inc. on Wednesday reached agreement on clean-air violations at plants in Ohio and Illinois.

SunCoke Energy Inc. and two of its subsidiaries have agreed to pay $1.995 million to resolve alleged federal Clean Air Act violations of emission limits at the Haverhill Coke plant in Scioto County in southern Ohio and the Gateway Energy and Coke plant in Granite City, Ill.

The companies will also spend $255,000 on a lead abatement project in southern Illinois to reduce lead hazards in owner-occupied low income residences with priority given to families with young children or pregnant women.

The companies will pay a penalty of $1.27 million to the United States, $575,000 to Illinois, and $150,000 to Ohio.

In addition, the companies will spend approximately $100 million at the two heat-recovery coking facilities to install equipment known as heat-recovery steam generators (HRSG) to ensure that hot coking gases are routed to pollution control equipment and not vented directly into the atmosphere.
