AG Raoul announced a lawsuit against Koppers Inc. (Koppers) and Koppers Carbon Materials LLC over the alleged continued environmental and human health effects from Koppers’ chemical manufacturing facility in Cicero, Illinois. The lawsuit alleges that on multiple occasions, Koppers violated state and federal environmental statutes and regulations by failing to properly operate pollution control equipment and conduct required testing and monitoring, which caused an excess of air pollutants, including volatile organic materials, to be emitted into the atmosphere. 

“Koppers has continuously failed to follow laws that protect against high levels of dangerous pollutants entering our atmosphere. I will continue to work to protect communities from the health and environmental impacts of pollution and hold companies accountable for violations of our environmental laws.” -AG Raoul
