Gateway West Final Environmental Assessment and Proposed Land Use Plan Amendments for Segments 8 and 9, Idaho Appendix G BLM and FWS Endangered Species Act [ESA] Compliance Memoranda January 5, 2018 United States Department of the Interior BUREAU OF LAND MANAGEMENT Idaho State Office 1387 S. Vinnell Way Boise, Idaho 83709 DEC 1 5 2017 In Reply Refer To: 2800 (930) WYW-174598/IDI-35849-01 Gateway West Transmission Line Project EMS TRANSMISSION Memorandum To: Field Supervisor, U.S. Fish and Wildlife Service, Wyoming Field Office, Cheyenne, WY From: JuneE. Shoemake~~ Deputy State Direc!9f, Bureau of Land Management, Idaho State Office Subject: Endangered Species Act Section 7 Compliance Memorandum v. 2.0 Introduction The Bureau of Land Management (BLM) is submitting this memorandum to the U.S. Fish and Wildlife Service (USFWS) to document changes in the Gateway West Transmission Line Project (Project) 2016 Final Supplemental Environmental Impact Statement (SEIS) and 2017 Environmental Assessment (EA) that have occurred to Segments 8 and 9 since the publication of the 2013 Final Environmental Impact Statement (FEIS) and 2013 Biological Assessment (BA). In our 2013 BA, BLM determined that the Project "may affect, but is not likely to adversely affect" the endangered Banbury Springs limpet (currently Lanx sp., technically now ldaholanx fresti; Campbell et al. 2017), Snake River physa (Physa natricina), and Bruneau hot springsnail (Pyrgulopsis bruneauensis); the threatened Bliss Rapids snail (Taylorconcha serpenticola); and designated critical habitat for the bull trout (Salvelinus confluentus). We also determined that the Project "may affect", and was "likely to adversel7 affect" slickspot peppergrass (Lepidiu:ri papilliferum) and its proposed critical habitat. This memorandum provides documentation of BLM's determination that the changes to Segments 8 and 9 presented in the 2016 SEIS and 2017 EA do not modify the effects analyzed for the Banbury Springs limpet, Snake River physa, Bruneau hot springsnail, Bliss Rapids snail, designated critical habitat for the bull trout, and slickspot peppergrass and its proposed critical habitat in a manner or to an extent not previously considered as described through criteria1 set forth in 50 CFR §402.16. In addition, current 1 As provided in 50 Code of Federal Regulations §402.16, reinitiation of formal consultation is required where discretionary federal agency involvement or control over the action has been retained (or is authorized by law) and if (1) the amount or extent of incidental take is exceeded;(2) new information reveals effects of the agency action that may affect Endangered Species Act listed species or critical habitat in a manner or to an extent not considered in the Biological Opinion; (3) the agency action is subsequently modified in a manner that causes an effect to the ESA-listed species or critical habitat not considered in the Biological Opinion; or (4) a new species is listed or critical habitat designated that may be affected by the action. 1 environmental baseline conditions for the Project area in Segments 8 and 9 have not significantly changed from those included in our effects analyses addressed in the 2013 BA. Thus, we have concluded that there will be no significant increase in the intensity or duration of any potential beneficial or adverse effects of Segments 8 and 9 of the Project, inclusive of associated conservation measures, as described in our 2013 BA. Therefore, BLM has determined that the 2013 BA adequately addresses any effects of Segments 8 and 9 such that reinitiation of Endangered Species Act (ESA) section 7 consultation is not necessary. We request USFWS acknowledgement that the existing section 7 consultation adequately addresses effects to listed species and bull trout critical habitat within Segments 8 and 9 as further described below in this memorandum. As described in detail below, BLM has determined that Alternative 1 for Segments 8 and 9 of the 2016 SEIS and 2017 EA "may affect" but are "not likely to adversely affect" Banbury Springs limpet, Snake River physa, and Bliss Rapids snail, and will have "no effect" on Bruneau hot springsnail and bull trout critical habitat. We request USFWS acknowledgement of this "may affect, not likely to adversely affect" determination for Banbury Springs limpet, Snake River physa, and Bliss Rapids snail, and "no effect" determination for Bruneau hot springsnail and designated critical habitat for bull trout for Segments 8 and 9 as described below in this memorandum. Slickspot peppergrass was reinstated as a threatened species on September 16, 2016, which was subsequent to the completion of the 2013 BA. As described below, we have determined that implementation of Alternative 1 for Segments 8 and 9 of the 2016 SEIS and 2017 EA "may effect", and is "likely to adversely affect" slickspot peppergrass in a manner or to an extent similar to that which was analyzed in the original 2013 BA and for which the Service provided its 2013 Conference Opinion (CO). We request USFWS acknowledgement of this "may effect, likely to adversely affect" determination for slickspot peppergrass and its proposed critical habitat for Segments 8 and 9 and further request USFWS confirm the conclusion of the 2013 CO as formal consultation and as the USFWS's Biological Opinion. In addition, the yellow-billed cuckoo (Coccyzus americanus) was designated as a threatened species on November 2, 2014, which was subsequent to the completion of the 2013 BA. As described below, we have determined that implementation of Alternative 1 for Segments 8 and 9 of the 2016 SEIS and 2017 EA will have "no effect" on the yellow-billed cuckoo or its proposed critical habitat. This analysis of Project-related effects on the yellow-billed cuckoo and its proposed critical habitat only addresses the 2016 SEIS and 2017 EA Alternative 1 for Segments 8 and 9 of the Project. We further request USFWS acknowledgement of this "no effect" determination for the yellow-billed cuckoo and its proposed critical habitat for Segments 8 and 9. Project Summary and Background The Project, as assessed in the 2013 FEIS and BA, included permanent and temporary access roads, laydown and staging areas, three substations, expansions or modifications of nine extant substations, and construction or installation of communications systems, optical fiber regeneration stations, and substation distribution supply lines. The design of the electric transmission line included self-supported steel H-frame 230-kilovolt (kV) structures and lattice steel 500-kV structures. The BA addressed only the routes selected as the Agency Preferred Alternative by the BLM in 2013, which included the construction and operations of about 990 miles of new 230-kV and 500-kV electric transmission lines in 10 segments, from the Windstar Substation at Glenrock, Wyoming, to the Hemingway Substation just west of Melba, Idaho. 2 The BLM published the FEIS for the Project on April 26, 2013 (BLM 2013a) and a Record of Decision (ROD) on November 14, 2013 (BLM 2013b). In that ROD, the BLM deferred a decision for two of the 10 segments (i.e., Segments 8 and 9) to allow additional time for federal, state, and local permitting agencies to examine additional routing options, compensatory mitigation measures, and the enhancement standard applicable to these segments where they intersect the Morley Nelson Snake River Birds of Prey National Conservation Area (SRBOP). A BA and a request for formal consultation were submitted to the USFWS in March 2013 and April 30, 2013, respectively. In September 2013, the BLM received a Biological Opinion (BO) from the USFWS [Ref#06E13000/WY13F0033] which contained (1) acknowledgement of "no effect" and concurrence for "not likely to adversely affect" determinations; (2) a BO for potential adverse effects associated with depletions from the Colorado and Platte River Basins; and (3) an attached Conference Opinion (CO) for effects of the Project on the proposed slickspot peppergrass and its proposed critical habitat. A summary of the ESA listed species analyzed in the 2013 BA and addressed in the 2013 BO and associated CO is provided in Attachment 1. The BO acknowledged that the Project would have "no effect" on an additional 14 ESA listed species that do not have the potential to occur in the Action Area (Attachment 2). In November 2013, following publication of the FEIS and BA, the BLM requested that the Boise Resource Advisory Council (RAC) consider issues surrounding the siting of Segments 8 and 9 of the Project and examined a number of additional routing options. In August 2014, the Proponents of the Project (i.e., Idaho Power Company and PacifiCorp, doing business as Rocky Mountain Power) submitted a revised Project application for Segments 8 and 9 based on recommendations from the RAC. This new application for Segments 8 and 9 was assessed in the BLM's 2016 SEIS and 2017 EA. The BLM published the SEIS for the Project on October 7, 2016 (BLM 2016a) and a ROD on January 19, 2017 (BLM 2017a). In that ROD, the SEIS Agency Preferred Alternative (Alternative 5 - Route 8G and Route 9K) was selected. Because the SEIS Alternative 5 had the potential to generate different impacts to ESA listed species or critical habitat compared to the Agency Preferred Alternatives considered in the FEIS/BA, the BLM prepared an ESA Section 7 Compliance Memorandum that was submitted to the USFWS on December 13, 2016 (BLM 2016b). On December 16, 2016, the USFWS provided the BLM a memorandum (USFWS 2016a) acknowledging the BLM's determinations outlined in the 2016 ESA Section 7 Compliance Memorandum. The Proposed Action and proposed land use plan amendments assessed in the 2017 EA are different from those selected in the 2017 ROD. Therefore, the analysis and determinations documented in the. 2016 ESA Section 7 Compliance Memorandum are no longer applicable. The BLM's 2016 SEIS and 2017 EA assesses the Proponents' new Revised Proposed Action for Segments 8 and 9 (Alternative l); new routes, variations, and alternatives for Segments 8 and 9; newly proposed design features and mitigation measures; as well as new information that has become available since the 2013 FEIS and ROD were published.
