California High-Speed Rail Project Bakersfield to Palmdale: Revised Draft Environmental Impact Report / Supplemental Draft Environmental Impact Statement

California High-Speed Rail Project Bakersfield to Palmdale: Revised Draft Environmental Impact Report / Supplemental Draft Environmental Impact Statement

A Statewide Program Environmental Impact Report/Environmental Impact Statement (EIR/EIS) (Tier 1) was certified in November 2005 as the first phase of a tiered environmental review process for the proposed California High-Speed Rail (HSR) system planned to provide a reliable, high-speed, electric powered rail system that links the major metropolitan areas of the state and that delivers predictable and consistent travel times. A further objective is to provide an interface with commercial airports, mass transit, and the highway network and to relieve capacity constraints of the existing transportation system as increases in intercity travel demand in California occur, in a manner sensitive to and protective of California’s unique natural resources. The California High-Speed Rail Authority (Authority) has prepared a Draft EIR/EIS that further examines the Bakersfield to Palmdale Project Section at the project level (Tier 2), within Kern and Los Angeles counties. The project examined is construction and operation of a grade-separated, dedicated double-track, electric powered, passenger, steel-wheel-on-steel-rail, high-speed railroad between Bakersfield and Palmdale, including a station in Bakersfield (approved by the Authority under CEQA in October 2018 and under NEPA in November 2019) and a station in Palmdale. Consistent with the Tier 1 decisions, the Bakersfield to Palmdale Project Section is approximately 80 miles in length and traverses valley, mountain, and high desert terrain, as well as urban, rural, and agricultural lands. From the north, this project section begins at the Bakersfield Station and travels south and southeast through the Tehachapi Mountains, then descends into the Antelope Valley, where it terminates at the Palmdale Station. The Draft EIR/EIS describes a no-project alternative and HSR Build alternatives (including alignment, station, and maintenance facility alternatives) and identifies potential impacts, benefits, and mitigation measures. Following the Authority’s publication of the Draft EIR/EIS in February 2020, the Authority learned that the California Fish and Game Commission advanced the Southern California and Central Coast mountain lion (Puma concolor) populations to candidacy for listing under the California Endangered Species Act. The Authority also learned that the U.S. Fish and Wildlife Service determined that listing the monarch butterfly (Danaus plexippus) under the Endangered Species Act is warranted, but that listing is precluded by other priorities; therefore, the monarch butterfly is now a candidate species under the Endangered Species Act. The U.S. Fish and Wildlife Service will review the species’ status annually until a listing decision is made. Both CEQA and NEPA provide guidance on the recirculation and supplementation of published environmental documents. Pursuant to pertinent requirements of both laws, the Authority, as lead CEQA and NEPA agency for the Bakersfield to Palmdale Project Section, is issuing this Revised Draft EIR/Supplemental Draft EIS limited to the portions of the Draft EIR/EIS to address new information about the mountain lion and the monarch butterfly. New information includes background information, impact analysis, and mitigation measures. In addition to providing new information about the mountain lion and monarch butterfly, the Authority has identified two new mitigation measures to address impacts to wildlife resulting from lighting during construction and during project operation. Other information that has not been revised, including the methods for evaluating impacts under NEPA and the methods for determining significance under CEQA, as well as the appendices and technical reports, can be found in the Draft EIR/EIS. The previously published Draft EIR/EIS, including Sections 3.7 and 3.19, is available on the Authority’s website (www.hsr.ca.gov).The sections comprising the Revised Draft EIR/Supplemental Draft EIS are: 1. Summary 2. Section 3.7, Biological and Aquatic Resources 3. Section 3.19.5.7, Cumulative Impacts, Biological and Aquatic Resources The Authority reviewed other sections of the Draft EIR/EIS and found, based on research and a review of the evidence, that no other substantive changes would be required. All revisions made in response to the updated information are being made in this Revised Draft EIR/Supplemental Draft EIS. All other subsections and appendices to Section 3.7 and the technical reports supporting Section 3.7 of the Draft EIR/EIS were not revised. Section 3.7 includes new mitigation measures. These will be incorporated into the Mitigation Monitoring and Enforcement Plan, to be included as part of the CEQA/NEPA decision documents.
