Endangered and Threatened Wildlife and Plants; Regulations for Designating Critical Habitat

We, the U.S. Fish and Wildlife Service (FWS), propose to amend portions of our regulations that implement section 4 of the Endangered Species Act of 1973, as amended (Act). The proposed revisions set forth a process for excluding areas of critical habitat under section 4(b)(2) of the Act, which mandates our consideration of the impacts of designating critical habitat and permits exclusions of particular areas following a discretionary exclusion analysis. We want to articulate clearly when and how FWS will undertake an exclusion analysis, including identifying a non-exhaustive list of categories of potential impacts for FWS to consider. The proposed rulemaking would respond to applicable Supreme Court case law, reflect agency experience, codify some current agency practices, and make some modifications to current agency practice. The intended effect of this proposed rule is to provide greater transparency and certainty for the public and stakeholders.
