Sierra Club v. Two Elk Generation Partners, LP, No. 10-8032 (10th Cir. 2011)
Annotate this Case
Plaintiff-Appellant Sierra Club filed a petition with the Tenth Circuit in an attempt to stop Defendant-Appellee Two Elk Generation Partners, LP (Two Elk) from building a coal-fired power plant in Wyoming. Sierra Club argued that Two Elk was building the plant in violation of the Clean Air Act, 42 U.S.C. 7604. For over ten years, Two Elk had planned to build the power plant, and filed the appropriate applications with the local environmental authorities to receive permission to start construction. In late 2007, state authorities notified Two Elk that its environmental permit had expired. In the process of getting the permit renewed, Sierra Club tried to intervene to stop the process. While Two Elk and Sierra Club were fighting one another in the state administrative bodies and courts, Sierra Club filed a citizen suit with the federal district court. The federal district court dismissed Sierra Club's case, holding that the state courts already decided the same issues in its suit. On appeal to the Tenth Circuit, Sierra Club argued that it was not a party to the permit-application proceedings, and that it should not be precluded from bringing suit now. Furthermore, the Club argued that the Clean Air Act established the circumstances under which a citizen suit may be brought, and those circumstances were not met at the state court level. Upon careful consideration of the arguments and the applicable legal authority, the Tenth Circuit affirmed the lower court's decision. The Court found that Sierra Club's arguments under the Clean Air Act were indeed precluded by decisions from the state court proceedings. The Court dismissed Sierra Club's appeal.
