Section 8 – Other Events

Item 8.01  Other Events.

As previously reported, since August 2009, Midwest Generation, LLC (“Midwest Generation”), an indirect subsidiary of Edison Mission Energy (“EME”) has been defending an action brought in the U.S. District Court for the Northern District of Illinois by the State of Illinois and the Department of Justice.  The complaint alleged violations of the Clean Air Act (“CAA”) and related regulations.  Among the allegations were ten counts alleging that Midwest Generation violated the CAA’s Prevention of Significant Deterioration (“PSD”) provisions by operating six power plants that Commonwealth Edison, a prior owner of the plants, had modified without obtaining PSD permits.  Nine of the ten counts related to PSD requirements were dismissed in March 2010, and the tenth count was also dismissed to the extent it sought civil penalties under the CAA, as barred by the applicable statute of limitations.

Following the 2010 dismissals, the government plaintiffs filed an amended complaint, with claims that attempted to add Commonwealth Edison and EME as defendants and introduce new legal theories to impose liability on Midwest Generation and EME. On March 16, 2011, the U.S. District Court again dismissed nine of the ten PSD claims asserted against Midwest Generation and EME, along with claims related to alleged violations of Title V of the CAA to the extent based on the dismissed PSD claims, and dismissed all claims asserted against Commonwealth Edison. The Court denied a motion to dismiss a claim by intervenor citizens groups for civil penalties in the remaining PSD claim, but noted that the plaintiffs would be required to convince the Court that the statute of limitations should be equitably tolled.

On July 8, 2013, the United States Court of Appeals for the Seventh Circuit affirmed the U.S. District Court’s dismissal of the nine PSD claims.

Other counts in the complaint that allege violations of opacity and particulate matter limitations under the Illinois State Implementation Plan and related claims under Title V of the CAA have not been dismissed.

A copy of the decision is attached hereto as Exhibit 99.1.
