(a) Regional Haze. The requirements of section 169A of the Clean Air Act are not met because the regional haze plan submitted by Indiana on January 14, 2011, and supplemented on March 10, 2011, does not include fully approvable measures for meeting the requirements of 40 CFR 51.308(d)(3) and 51.308(e) with respect to emissions of NOX and SO2 from electric generating units. EPA has given limited approval and limited disapproval to the plan provisions addressing these requirements.

(b) Measures Addressing Limited Disapproval Associated with NOX. The deficiencies associated with NOX identified in EPA's limited disapproval of the regional haze plan submitted by Indiana on January 14, 2011, and supplemented on March 10, 2011, are satisfied by § 52.789.

(c) Measures Addressing Limited Disapproval Associated with SO2. The deficiencies associated with SO2 identified in EPA's limited disapproval of the regional haze plan submitted by Indiana on January 14, 2011 and supplemented on March 10, 2011 are satisfied by § 52.790.
