On June 16, 2023, in a highly anticipated decision, the United States Court of Appeal for the D.C. Circuit set aside a biological opinion regarding the effects of the federal lobster fishery on the North Atlantic right whale (Eubalaena glacialis). The court held that a presumption in favor of an endangered species is not required by the Endangered Species Act (ESA) and, further, that such a presumption can distort the agency’s scientific judgment and did so in this circumstance.

The National Marine Fisheries Service (NMFS) issued the biological opinion in 2021 analyzing the ...

On May 17, 2023, the federal District Court for the District of Massachusetts granted summary judgment in favor of the United States Bureau of Ocean Energy Management (BOEM) and Vineyard Wind and denied summary judgment to the plaintiffs in the case of Nantucket Residents Against Turbines v.

On September 8, 2020, the U.S. Fish and Wildlife Service (USFWS) published a proposed rule codifying procedures for excluding areas of “critical habitat” under section 4 of the Endangered Species Act (ESA). ESA section 4(b)(2) provides discretionary authority to the USFWS and National Marine Fisheries Service (NMFS), as administrators of the ESA, to exclude certain areas from critical habitat designations for species within their purview. These agencies can exclude areas from a critical habitat designation where the agencies conclude the benefits of excluding the areas ...

Many projects require federal incidental take authority due to impacts on species listed under the federal Endangered Species Act (“ESA”). Depending upon the species, this federal take authority is obtained either from the U.S. Fish and Wildlife Service (“USFWS”) or National Marine Fisheries Service (“NMFS”). These agencies provide take authority either through a Section 7 (federal consultation) incidental take statement or Section 10 (Habitat Conservation Plan) incidental take permit. These authorizations almost always require the permittee to undertake ...

The State of California recently sent a 60-day notice of intent to sue to the Secretaries of Commerce and the Interior and concurrently filed a lawsuit in the U.S. District Court for the Northern District of California challenging the biological opinions and associated environmental impact statement (EIS) for operation of the Central Valley Project and State Water Project (collectively, the “Projects”).  The Projects provide water to more than 25 million water users in northern, central, and southern California, and are one of the primary sources of water for wholesale water ...

The submission deadline for comments was September 24, 2018.  If enacted, the Services assert that the proposed revisions would, among other things, streamline ESA consultations with other federal agencies and clarify the jeopardy standard.

The proposed revisions sparked a flurry of last minute comment submissions from environmental groups, who ...

In recent weeks, the Trump Administration and Congress have proposed changes to the Endangered Species Act (ESA) and its implementing regulations. Lawmakers from the Congressional Western Caucus introduced nine bills that would, according to the 15 legislators that introduced the bills, amend and modernize the ESA.  The lawmakers assert that the bills would also incentivize voluntary conservation efforts, let states enter into cooperative agreements for recovery, and prioritize data from local communities in making scientific decisions about conservation.

The bills ...

The most comprehensive Endangered Species Act (ESA) bill of this Congressional session made its debut on July 2, 2018 when Senator John Barrasso (R-Wyo.), Chairman of the Senate Environment and Public Works (EPW) Committee, released a discussion draft of a bill proposing sweeping revisions to the ESA.  The discussion draft is a culmination of activity that began February 15, 2017, when the EPW committee held an oversight hearing on modernization of the ESA. Following that hearing, Senator Barrasso worked closely with the Western Governors’ Association (WGA) in drafting the ...

On May 16, 2018, the House Committee on Natural Resources passed six bills, including the Federally Integrated Species Health Act (H.R. 3916).  H.R. 3916 is sponsored by Representative Ken Calvert, a Republican representing the 42nd Congressional District in California.  The bill proposes to amend the federal Endangered Species Act to vest the Secretary of Interior with Endangered Species Act authority over fish species that migrate between fresh and ocean waters, such as the endangered Sacramento River winter-run Chinnok salmon (Oncorhynchus tshawytscha).  ...
