{"abstract":"Under the Endangered Species Act (ESA), the Secretary of Commerce (Secretary) is required to adopt such regulations as he deems necessary and advisable for the conservation of species listed as threatened. This proposed ESA 4(d) rule would apply the take prohibitions enumerated in section 9(a)(1) of the ESA in most circumstances to California Central Valley Chinook, California Coastal Chinook and Northern California steelhead that do not currently have 4(d) protective regulations in place. However, for these three threatened ESUs, NMFS is proposing 10 categories of activities for which the take prohibitions would not apply. NMFS believes that these activities contribute to conserving the listed salmonids or are governed by certain programs that adequately limit impacts on the ESUs. For the threatened Central California Coast coho salmon ESU, a 4(d) rule is currently in place which generally applies the take prohibitions enumerated in section 9(a)(1) of the ESA to this ESU. For this ESU, NMFS is proposing to amend its existing regulations to allow the same 10 limits on the application of the take prohibitions which are proposed for the chinook and steelhead ESUs described here.","action":"Proposed rule; request for comments.","agencies":[{"raw_name":"DEPARTMENT OF COMMERCE","name":"Commerce Department","id":54,"url":"https://www.federalregister.gov/agencies/commerce-department","json_url":"https://www.federalregister.gov/api/v1/agencies/54","parent_id":null,"slug":"commerce-department"},{"raw_name":"National Oceanic and Atmospheric Administration","name":"National Oceanic and Atmospheric Administration","id":361,"url":"https://www.federalregister.gov/agencies/national-oceanic-and-atmospheric-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/361","parent_id":54,"slug":"national-oceanic-and-atmospheric-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2001/08/17/01-20570.html","cfr_references":[{"chapter":null,"citation_url":null,"part":223,"title":50}],"citation":"66 FR 43150","comment_url":null,"comments_close_on":"2001-10-01","correction_of":null,"corrections":[],"dates":"Comments on this proposed rule must be received at the appropriate address (see ADDRESSES), no later than 5 p.m., Pacific standard time, on October 1, 2001.
