    09/30/2022 Opinion Download Dismissal of case reversed. Tenth Circuit Said District Court Erred in Dismissing Challenge to Dam Permit. The Tenth Circuit Court of Appeals ruled that a federal district court erred when it concluded that the Federal Power Act vested the courts of appeals with exclusive jurisdiction over a challenge to a U.S. Army Corps of Engineers permit that was required for modification of a dam project licensed by the Federal Energy Regulatory Commission. The environmental groups challenging the Corps permit contended, among other things, that the Corps violated the National Environmental Policy Act by failing to fully consider the impacts of climate change. The Tenth Circuit reversed the district court’s dismissal of the case and remanded for further proceedings.

    03/31/2021 Order Download Motions to dismiss granted. Federal Court Dismissed Challenge to Colorado Dam Project Authorizations for Lack of Jurisdiction. The federal district court for the District of Colorado agreed with federal respondents that the Federal Power Act (FPA) required that petitioners’ challenges to U.S. Army Corps of Engineers and U.S. Fish and Wildlife Service (FWS) actions authorizing a dam project in Colorado be brought in a federal court of appeal. The district court noted that the FPA vests federal courts of appeal with exclusive jurisdiction to review not only the licensing orders of the Federal Energy Regulatory Commission (FERC) but also “all issues inhering in the controversy” related to a FERC order. In this case, the court found that the Corps, FERC, and FWS decisions were “inextricably intertwined.” The court therefore dismissed the case—which alleged, among other things, that the federal agencies failed to take into account climate change impacts and future climate change models—for lack of jurisdiction.

    12/19/2018 Petition for Review Download Petition for review of agency action filed. Environmental groups filed a lawsuit challenging the U.S. Army Corps of Engineers' authorization of the construction and operation of the tallest dam in Colorado history. They asserted that the Corps violated the National Environmental Policy Act (NEPA), the Clean Water Act, and the Endangered Species Act by, among other things, failing to take into account climate change impacts and future climate change models. The groups contended that the Corps violated NEPA by failing to "independently establish" that the project would achieve its stated purpose "in light of consensus-based projects of climate change." Under the Endangered Species Act, the groups asserted that the U.S. Fish and Wildlife Service had relied on outdated population estimates to quantify the take of cutthroat trout, including by failing to account for recent evidence of climate change.
