SUPPLEMENTARY INFORMATION:

The CAA affords EPA a 45-day period to review and, as appropriate, the authority to object to operating permits proposed by state permitting authorities under title V of the CAA, 42 U.S.C. 7661-7661f. Section 505(b)(2) of the CAA and 40 CFR 70.8(d) authorize any person to petition the EPA Administrator to object to a title V operating permit within 60 days after the expiration of EPA's 45-day review period if EPA has not objected on its own initiative. Petitions 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 these issues during the comment period or the grounds for the issues arose after this period.

Petitioners submitted the first of two petitions regarding the LG&E Trimble County Generating Station on March 2, 2006, requesting that EPA object to Revision 2 to the LG&E merged prevention of significant deterioration and title V operating permit. The second petition, regarding Revision 3 to the merged permit, was submitted on April 29, 2008. On September 10, 2008, EPA issued a “Partial Order Responding to March 2, 2006, Petition and Denying in Part and Granting in Part Request for Objection to Permit Revision 2.” In the September 2008 Order, EPA explained that some issues raised in Petition 1 were affected by permit Revision 3 and also discussed in Petition 2. At this time, EPA is addressing all the remaining issues identified by Petitioners in Petitions 1 and 2.

Petitioners alleged that the permit was not consistent with the CAA for the following reasons: (1) Public participation procedures were not adequate; (2) the permit failed to include requirements for addressing green house gases; (3) the best available control technology (BACT) analysis for nitrogen oxides and sulfur dioxide was not adequate; (4) BACT for the auxiliary boiler and emergency diesel generator were not adequate; (5) BACT for support operations was not adequate; (6) BACT for particulate matter (PM) and particulate matter with a diameter less than or equal to ten micrometers (PM10) was not adequate; (7) BACT for sulfuric acid mist (SAM) was not adequate; (8) the permit failed to consider particulate matter with a diameter less than or equal to 2.5 micrometers; (9) the permit failed to express limits in an adequate manner; (10) BACT analyses did not include clean fuels; (11) the permit lacked a maximum achievable control technology determination for mercury and other hazardous air pollutants; (12) the emission limits for SAM, PM/PM10, and mercury were not enforceable (compliance assurance monitoring concerns); and (13) the permit improperly relied on manufacturer specifications that are not included in the permit, did not identify test methods, and additional concerns regarding netting.

On August 12, 2009, the Administrator issued an Order partially granting and partially denying the petition. The Order explains EPA's rationale for granting the petition with respect to issues 4 and 8, above, and denying on the other issues.
