Item  8.01
Other Events
Midwest Generation Environmental Permit
On November 19, 2010, the Illinois Environmental Protection Agency issued a construction permit to Midwest Generation authorizing the construction of flue gas desulfurization ("FGD") equipment and particulate emissions controls at the Waukegan Generating Station's Unit 7.
The construction permit authorizes Midwest Generation to install a dry sorbent injection system using Trona or its equivalent to meet the SO
2
reduction and FGD equipment requirements contained in the Illinois Combined Pollutant Standard ("CPS").  The permit also authorizes Midwest Generation to
convert the existing electrostatic precipitator to a "cold-side" design which will improve removal efficiency of particulate matter to satisfy the particulate control requirements of the CPS.
Midwest Generation has not made final decisions as to whether the project will be undertaken at Unit 7 and its decision remains subject to various factors, such as market conditions, regulatory and legislation developments, forecasted commodity prices, and applicable capital and operating costs.  Illinois regulations require construction to begin under the permit within twelve months of the date the permit was granted.
For more discussion regarding Midwest Generation's permitting and planning activities, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Management's Overview—Environmental Developments—Environmental Compliance Plans and Costs" in Midwest Generation's Form 10-Q for the period ended September 30, 2010.
