The 10th Circuit Rules a Clean Air Act Citizen Suit is Time-Barred
Applicable Statute of Limitations is Triggered on the First Day of a Continued Permitting Violation
Last week, the 10th Circuit Court of Appeals affirmed dismissal of a Sierra Club citizen suit against a coal-fired power plant for an alleged permitting violation of the Clean Air Act, finding that the Sierra Club’s claims were time-barred. In the case, Sierra Club v. Okla. Gas & Elec. Co., No. 14-7065 (10th Cir. March 8, 2016), the court held that the Sierra Club’s claims for civil penalties were statutorily time-barred because they were brought more than five years after the power plant began its unpermitted modification of a boiler, an action which the Sierra Club claims violated the Prevention of Significant Deterioration (PSD) program under the Clean Air Act. The court also affirmed dismissal of the group’s claims for injunctive and declaratory relief because those legal claims were predicated on the same facts as the time-barred civil penalties. The court’s interpretation of the statute of limitations as applied to the PSD program is consistent with a 2011 district court decision in the 3rd Circuit, United States v. EME Homer City Generation L.P., et al., which we reported on here.
