Endangered and Threatened Wildlife and Plants: Proposed Rulemaking To Designate Critical Habitat for the Main Hawaiian Islands Insular False Killer Whale Distinct Population Segment

We, NMFS, propose to designate critical habitat for the Main Hawaiian Islands insular false killer whale (Pseudorca crassidens) distinct population segment by designating waters from the 45-meter (m) depth contour to the 3200-m depth contour around the main Hawaiian Islands from Niihau east to Hawaii, pursuant to section 4 of the Endangered Species Act (ESA). Based on considerations of economic and national security impacts, we propose to exclude the following areas from designation because the benefits of exclusion outweigh the benefits of inclusion and exclusion will not result in extinction of the species: The Bureau of Ocean Energy Management's Call Area offshore of the Island of Oahu, the Pacific Missile Range Facilities Offshore ranges (including the Shallow Water Training Range, the Barking Sands Tactical Underwater Range, and the Barking Sands Underwater Range Extension), the Kingfisher Range, Warning Area 188, Kaula and Warning Area 187, Fleet Operational Readiness Accuracy Check Site Range, the Shipboard Electronic Systems Evaluation Facility, Warning Areas 196 and 191, and Warning Areas 193 and 194. In addition, the Ewa Training Minefield and the Naval Defensive Sea Area are precluded from designation under section 4(a)(3) of the ESA because they are managed under the Joint Base Pearl Harbor-Hickam Integrated Natural Resource Management Plan that we find provides a benefit to the Main Hawaiian Islands insular false killer whale. We are soliciting comments on all aspects of the proposal, including information on the economic, national security, and other relevant impacts. We will consider additional information received prior to making a final designation.
