(a) Reasonably Attributable Visibility Impairment. The requirements of section 169A of the Clean Air Act are not met because the plan does not include fully approvable measures for meeting the requirements of 40 CFR 51.305 for protection of visibility in mandatory Class I Federal areas.
(b) Regulation for visibility monitoring. The provisions of Sec. 52.26 are hereby incorporated and made a part of the applicable plan for the State of Texas.
(c) Regional Haze. The requirements of section 169A of the Clean Air Act are not met because the regional haze plan submitted by Texas on March 31, 2009, 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 disapproval to the plan provisions addressing these requirements.
