On August 27, 2019, the U.S. Fish and Wildlife Service and National Marine Fisheries Service (collectively, the “Services”) published final rules amending three important parts of the federal regulations that implement the Endangered Species Act (16 U.S.C. §§ 1531 et seq.). The amended rules, which will take effect on September 26:

  • Eliminate the automatic extension of protections to threatened (as opposed to endangered) species;
  • Revise the provisions for designating critical habitat and listing and de-listing species under ESA Section 4; and
  • Revise the procedures for interagency consultation under ESA Section 7.

The Ninth Circuit Court of Appeals recently upheld – for the second time – California’s Low Carbon Fuel Standard (“LCFS”) against constitutional challenges brought by industry groups. The case, Rocky Mountain Farmers Union v. Corey (9th Cir. 2019) (No. 17-16881) (“Rocky Mountain II”), considered the groups’ claims that all 3 historical versions of the LCFS violate the Commerce Clause and the “federal structure of the Constitution” by regulating extraterritorially. The court held that while the plaintiff’s claims had changed form since the first time the court upheld the LCFS, “both the regulations and the claims have the same core structure now as they did then.” The court used this similarity to guide its analysis and uphold the district court’s dismissal.

An area designated as critical habitat under the Endangered Species Act must first qualify as “habitat” for listed species, the Supreme Court held this week in the closely watched Weyerhaeuser case. The Court’s November 27, 2018 ruling, which reversed a decision by the Fifth Circuit, has the potential to narrow federal agencies’ discretion to designate as critical habitat areas that are currently unoccupied by endangered or threatened species, but the opinion leaves important questions to be answered by the lower courts – including the meaning of “habitat.” The Court also held that agency decisions not to exclude specific areas from a critical habitat designation on economic grounds are subject to judicial review, reversing the Fifth Circuit and overturning the current law in the Ninth Circuit.
