Utility Air Regulatory Group v. EPA, No. 12-1342 (D.C. Cir. 2018)
Annotate this CaseConservation petitioners challenged the portion of the EPA's Final Rule, which implemented Congress's effort to restore air quality and visibility in certain national parks and wilderness areas (Class I areas), allowing states to treat Cross-State Air Pollution Rule (CSAPR) compliance as a better-than-BART (Best Available Retrofit Technology) alternative. State and Industry petitioners challenged EPA's disapproval of State Implementation Plans (SIPs) relying on the Clean Air Interstate Rule (CAIR) as a better-than-BART alternative. The DC Circuit held that conservation petitioners' first main challenge was moot; the attack on EPA's use of presumptive BART was jurisdictionally foreclosed; EPA's rule requires aggregate average improvement, and its comparison of the CSAPR-region Class I areas as well as all Class I areas nationwide was reasonable; and the remaining claims failed. Because the court found no merit in the conservation petitioners' arguments and could afford no relief to the state and industry petitioners, the court denied the petitions.
