# SUPPLEMENTARY INFORMATION:

The Act affords EPA a 45-day period to review, and object to as appropriate, operating permits proposed by state permitting authorities. Section 505(b)(2) of the Act authorizes any person to petition the EPA Administrator within 60 days after the expiration of the EPA review period to object to state operating permits if EPA has not done so. A petition must be based only on objections to the permit that were raised with reasonable specificity during the public comment period provided by the state, unless the petitioner demonstrates that it was impracticable to raise issues during the comment period, or the grounds for the issues arose after this period.

                    On October 3, 2009, David Bender of McGillivray Westerberg & Bender LLC, submitted a petition to EPA on behalf of the Sierra Club, requesting that EPA object to the Title V operating permit for the Alliant Energy—WPL Edgewater Generating Station. The petition raised issues regarding: (1) The alleged failure to include maximum gross generation, heat input and fuel usage limits that were contained in preconstruction permit applications as enforceable                           ( print page 55792)                        limits in the permit; (2) the sufficiency of particulate matter (PM) and opacity monitoring; and (3) the alleged failure of WDNR to include in the permit plans it relied upon in issuing the permit and to make those plans available for public notice and comment.                

On August 18, 2010, the Administrator issued an order granting in part and denying in part the petition. The order explains the reasons behind EPA's conclusions.

Dated: September 1, 2010.

Susan Hedman,

Regional Administrator, Region 5.
