On Dec. 16, the U.S. Department of Justice lodged an agreement to modify Consent Decree at the U.S. District Court for the Southern District of Indiana in the lawsuit against Southern Indiana Gas & Electric.
The new agreement will modify a Consent Decree entered in August 2003, which resolved Clean Air Act (CAA) claims against Southern Indiana Gas & Electric (SIGEGO), at its coal-fired F.B. Culley Generating Station. Under the proposed change, SIGECO has agreed, among other things, to construct and permanently operate sorbent injection systems at both Culley and its coal-fired A.B. Brown Generating Station to mitigate sulfuric acid emissions and meet specified emission limits at those plants, said Justice in a notice to be published in the Dec. 23 Federal Register.
The proposed deal also resolves a CAA Notice of Violation issued to SIGECO by the U.S. Environmental Protection Agency in November 2011.
The publication of this Dec. 23 notice will open a 30-day period for public comment.
SIGECO is a subsidiary of Vectren Corp. (NYSE: VVC).
