InMIDWEST ~~August 2009~~GENERATION, ~~Midwest Generation,~~ LLC (~~“Midwest Generation”~~Registrant) ~~was~~/s/ ~~sued~~Maria inRigatti ~~the~~Maria ~~U.S.~~Rigatti ~~District~~Manager ~~Court for the Northern District of Illinois by the State of Illinois~~ and ~~the~~Vice U.S. Department of Justice for claimed violations of New Source Review (“NSR”) related requirements under the Clean Air Act (“CAA”) related to its Illinois coal fired generating stations. Certain citizen groups intervened in the case as additional plaintiffs. Edison Mission Energy (“EME”) was subsequently named as an additional defendant.President

OnDate: ~~March 16,~~January ~~2011~~6, ~~the~~2012 Court dismissed all pending claims in this case against all then named defendants to the extent the claims relied on alleged modifications of Midwest Generation’s plants by Commonwealth Edison (“ComEd”), their prior owner, before the plants were sold to Midwest Generation. The Court’s action came about a year after similar dismissals in 2010, which resulted in amended complaints by the plaintiffs. The amended complaints, among other things, had sought civil penalties and injunctive remedies as a result of ComEd having modified certain of the units without obtaining specified pre-construction permits that would have required the installation of so-called Best Available Control Technology (“BACT”) at the time of the plant modifications. The Court also dismissed claims that Midwest Generation’s continued operation of the ComEd modified plants without BACT violates the CAA’s Title V operating permit requirements.

As a result of these dismissals, the only NSR and BACT related claims in the case that have not been dismissed are those against EME and Midwest Generation for civil penalties and injunctive remedies that relate solely to alleged modifications by Midwest Generation of its Will County 4 unit. As to these, the governments’ claim for civil penalties was dismissed as time-barred, but the citizen groups were given the opportunity to convince the Court that the statute of limitations should be equitably tolled as to them.

There also remain those counts in the original complaints that allege violations of opacity and particulate matter provisions of the Illinois State Implementation Plan and related claims under Title V of the CAA. There was no motion to dismiss these counts, and the Court’s March 16th decision did not address them.

A copy of the Court’s Order and Opinion is attached hereto as Exhibit 99.1.

U.S. Environmental Protection Agency’s Proposed Hazardous Air Pollutant Standards

Based on a preliminary review, Midwest Generation does not expect to change approach to compliance with state and federal environmental regulations as a result of of the U.S. EPA’s draft “National Emission Standards for Hazardous Air Pollutants,” issued March 16, 2011. Midwest Generation will continue to develop and implement a compliance program that includes the use of Activated Carbon Injection, upgrades to particulate removal systems and dry sorbent injection to meet mercury, acid gas and non-mercury metal emission limits.
