Some of these species are also state-listed threatened, endangered, and proposed species. The purpose of the BE is to document activities in sufficient detail to determine how the project may affect threatened, endangered, proposed, or sensitive species and their habitats (U.S. Forest Service Manual [USFSM] 2670.5). USFSM 2672.4 directs the U.S. Forest Service (USFS or Forest Service) to complete a BE for all Forest Service– planned, funded, executed, or permitted programs and activities to evaluate possible effects on threatened, endangered, candidate, proposed, and FSS species. The BE assists in determining whether a proposed project or any of the alternatives will result in a trend toward the sensitive species becoming federally listed. The project is required under the license terms and conditions for the Upper American River Project (UARP), Federal Energy Regulatory Commission (FERC) Project No. 2101, which was issued by FERC on July 23, 2014. Specifically, USFS 4(e) Condition No. 45 (j) – Specific Recreation Measures requires that SMUD redesign and reconstruct Sunset Campground by December 31, 2019. USFS 4(e) Condition No. 38 – Wildlife and Plant Protection Measures requires that SMUD prepare a BE before commencing any new construction or maintenance (including, but not limited to, proposed recreation developments) authorized by the license on USFS lands (Appendix A). This BE was developed to comply with components of these conditions that are relevant to the project. The UARP was constructed from 1959 to 1985 on USFS lands and consists of 7 developments within the Rubicon River, Silver Creek, and South Fork American River drainages. It consists of 8 hydroelectric power plants operating from 11 reservoirs, with a combined installed capacity of 637 megawatts (MW). In all, the UARP has 11 reservoirs, 8 powerhouses, 11 transmission lines with a combined length of 180 miles, 28 miles of power tunnels or penstocks, 1 canal, and 700 developed public- use campsites in 47 recreation areas, including Sunset Campground. The location of the UARP, including the proposed project, is shown in Figure 1.

Sacramento Municipal Utility District Upper American River Project 2 FERC Project No. 2101 Sunset Campground Rehabilitation Project Biological Evaluation - Terrestrial September 2017 1.1 Special-status Species Addressed in this Biological Evaluation For the purposes of this document, special-status species are defined as any species granted status by the U.S. Fish and Wildlife Service (USFWS) as threatened (FT), endangered (FE), candidate (FC), or delisted (FD), or species that have been designated by USFS as FSS. Some of these species may also be granted status by California Department of Fish and Wildlife (CDFW) as California Endangered (CE), California Threatened (CT), California Species of Special Concern (CSC), California Fully Protected (CFP), or by CDFW as Watchlist. Table 1 provides a list of special-status species that have potential to occur in the project area as identified in the USFWS Species List (USFWS 2016a), California Natural Diversity Database (CNDDB; 2016), and Regional Forester’s List of Sensitive Animal Species for Region 5 (USFS 2013a). Table 1 also provides the potential for each of these species to occur within the project area. Special-status species that are known to occur or have potential to occur in the project area are listed in Section 1.1.1 below. Special-status species that are shown in Table 1 as unlikely to occur are not addressed further in this document. This document includes analysis of the potential effects of the proposed project on the federally endangered Sierra Nevada yellow-legged frog (Rana sierrae; SNYLF) (FE and FSS). The project is not located within critical habitat for this species. The closest critical habitat unit (Subunit 2E: Crystal Range) is located 6 miles northeast of the project area (Figure 2). FERC, in its Order Issuing New License for Project No. 2101, acknowledged that the SNYLF was federally listed on April 29, 2014, with proposed critical habitat designated on April 25, 2013. The UARP is located in designated critical habitat for the SNYLF. However, in the Order, FERC noted the historical absence of SNYLF within the UARP reservoirs and affected reaches, further noting that the license measures will actually increase potential habitat for the SNYLF, as described in the Final Environmental Impact Statement (FEIS) for the relicensing of the UARP (USFS and FERC 2008; Sections 3-91–92; 3-193–194; 3-208–228; 5–18). FERC also acknowledged that the Order requires SMUD to monitor for the presence of SNYLF over the life of the license. As the lead federal action agency for the UARP, FERC concluded with the determination that the continued operation of the UARP, “will not affect this federally listed frog” and “would not destroy or adversely modify proposed Critical Habitat” (FEIS paragraphs 90–94:21–22).1 Lastly, FERC stated that “if the frog is found during 1 It should be noted that although critical habitat was identified as “proposed” in the 2014 FERC license for the UARP, in 2016, USFWS designated final critical habitat. However, in the case of the UARP, the extent of the “proposed” critical habitat did not change within the UARP sub-unit when it became “designated.” As such, the determination made by FERC still applies. Sacramento Municipal Utility District Upper American River Project 3 FERC Project No. 2101 Sunset Campground Rehabilitation Project Biological Evaluation - Terrestrial September 2017 monitoring, ESA [Endangered Species Act] consultation with USFWS may be needed in the future.” This BE, which describes design criteria to avoid impacts to this species, is an environmental measure prescribed by the FEIS for the UARP License. It provides additional site-specific analysis to support the “no effect” determination by FERC.
