Sid Richardson Carbon and Energy Company has agreed to install and operate state-of-the-art pollution control technologies to reduce emissions of harmful air pollutants. In addition to the controls, estimated to cost over $100 million, Sid Richardson will pay civil penalties of $999,000, and perform environmental mitigation projects valued at $490,000. This settlement resolves claims, alleged in a complaint filed today in federal court in Louisiana, that Sid Richardson failed to obtain permits and install and maintain appropriate emissions reduction technology at its three carbon black production facilities located in Addis, Louisiana; Big Spring, Texas; and Borger, Texas, as required under the Prevention of Significant Deterioration provisions and/or Maximum Achievable Control Technology Standards of the Clean Air Act.
