3 PROJECT RESOURCE SUMMARY 1 INTRODUCTION In 1999, the U.S. Department of the Interior, Bureau of Reclamation (Reclamation), the U.S. Fish and Wildlife Service (USFWS), the National Oceanic and Atmospheric Administration National Marine Fisheries Service (NMFS), the California Department of Fish and Game (CDFG), and the Pacific Gas and Electric Company (Licensee) all were signatories to a Memorandum of Understanding (MOU) (Appendix 1) that proposed the Battle Creek Salmon and Steelhead Restoration Project (Restoration Project). The proposed Restoration Project presents an opportunity to reestablish approximately 42 miles of prime salmon and steelhead habitat on Battle Creek, plus an additional 6 miles of habitat on its tributaries (Figure PRS-1). Restoration will be accomplished primarily through the modification of the existing Battle Creek Hydroelectric Project (Federal Energy Regulatory Commission [FERC] Project No. 1121) (Hydroelectric Project) facilities and operations, including instream flow releases. These proposed changes to the Hydroelectric Project trigger the need for the Licensee to seek a license amendment from FERC. The signatories to the MOU have decided to implement the Restoration Project in phases, each of which has independent ecological and environmental benefits. The Licensee is filing this license amendment application in order to permit the implementation of Phase 1A of the Restoration Project. This section provides a summary of the proposed license PRS 1

4 amendment for the Hydroelectric Project in support of Phase 1A of the Restoration Project. 1.1 Amendment Principles The Licensee has been guided by a number of principles derived from the provisions of the Federal Power Act (FPA) as amended by the Electric Consumers Protection Act of 1986 (ECPA) in developing this license amendment application. While the FPA requires FERC to give equal consideration to power and non-power values, these values are often competing and FERC is not required to optimize any single resource. Ultimately, the proposal for continued operation must be best adapted to a comprehensive plan for the waterway affected by the Hydroelectric Project. Key principles that have guided the Licensee in the development of this license amendment application are enumerated below. (1) The Environmental Baseline Is the Existing Project. For the purposes of a license amendment, FERC has held that the effects of a project will be measured against a baseline of current conditions (FERC Order 513 [June 2, 1989] 54 Fed. Reg , ). Any proposed change to the design or operation of the Hydroelectric Project facilities for either developmental or environmental enhancement purposes must be compared to existing conditions, not pre-project conditions, to determine whether such proposals result in an amended Hydroelectric Project that is best adapted to the comprehensive use of the waterway. PRS 2

5 The current environmental setting includes certain flow conditions as set forth in an Interim Flow Agreement (Agreement ). Under the Interim Flow Agreement, certain instream flows and management of existing fish facilities have been temporarily modified by agreement between Reclamation and the Licensee, with concurrence from CDFG. These conditions are provided for under temporary provisions to the operation of the Hydroelectric Project. The Interim Flow Agreement is intended to provide favorable flow conditions in advance of the Restoration Project. For the purposes of analyzing flow-related resource impacts, the resource agencies have agreed that the Interim Flow Agreement is not included in the environmental baseline. The Final Environmental Impact Statement (EIS)/Environmental Impact Report (EIR), Exhibit E, uses the current license conditions as the environmental baseline. (2) Balancing of Resources. Not all resources can be optimized simultaneously; therefore, decisions regarding the future of competing resources require careful consideration and trade-offs. (3) Economically Viable Hydroelectric Projects Are in the Public s Best Interest. Both resource assessment and resource enhancement must be commensurate with the scope of the Hydroelectric Project and must be justified by the potential resource benefits. Enhancements must maintain the economic viability of the Hydroelectric Project, an important source of clean, renewable electricity. PRS 3

6 (4) Value of Hydroelectricity. Hydropower historically has played an essential role in moderating energy prices in the Licensee s service territory. The majority of the Licensee s hydro resources are operated as peaking resources to help meet the daily changes in electric system demands. Hydropower s dispatch and spinning reserve capabilities are also important characteristics. Hydro capacity has a high unit ramp rate and can easily, quickly, and economically vary output in response to changing customer loads and system conditions. Hydropower has one of the highest availability and reliability rates of all generation resources. (5) Hydroelectricity is a Non-Consumptive Use of a Renewable Resource. Society benefits from this indigenous, renewable resource because it directly displaces the use of non-renewable fossil fuels. Hydropower is a nonconsumptive use of a water resource that is well integrated into water supply, irrigation, flood control, and other multi-purpose projects. In addition, investorowned utilities in California (such as the Licensee) are currently under an obligation to ensure that by the year 2010, twenty (20) percent of total retail sales of electricity are from eligible renewable energy resources. For hydroelectric power, California law defines powerhouses less than thirty (30) megawatts (MW) as eligible renewable energy resources. Because all of the Hydroelectric Project powerhouses meet this criterion, it is critical to minimize the loss of electric generating capacity as a result of the Restoration Project. PRS 4

7 (6) Natural Resources Stewardship. The Licensee s corporate environmental policy states that it is committed to being an environmental leader by providing safe, economical, and reliable products and services in a responsible and environmentally sensitive manner. The Restoration Project is a proactive, cooperative undertaking among the public, interested parties, the Greater Battle Creek Watershed Working Group (GBCWWG), state and federal agencies, and the Licensee to help restore the anadromous fish population in the Sacramento River watershed, where funding and restoration potential are uniquely promising. The Licensee and the Restoration Project proponents carefully analyzed and weighed all affected resources and believe the Restoration Project strikes a balance between the competing power and non-power benefits that the Hydroelectric Project provides. 1.2 License Amendment Process This license amendment application is filed in compliance with 18 Code of Federal Regulations (CFR) 4.201, 4.34(i) and The Hydroelectric Project was licensed in 1976 under regulations that since have been revised. In reviewing how best to prepare this license amendment application, the Licensee, in consultation with FERC staff, decided to amend the license using the new exhibit nomenclature for the written exhibits and maintaining the license s existing nomenclature for the exhibit drawings. 1 FERC approved the Licensee s request to use alternative procedures for the license amendment on March 1, PRS 5

8 The Licensee prepared an Initial Statement and Exhibits A, B, C, and D. As permitted under 18 CFR 4.34(i)(6)(iv), the Licensee is substituting the Restoration Project EIS/EIR Report July 2005 prepared by Reclamation and State Water Resources Control Board for the Restoration Project in place of an Exhibit E. This license amendment application supports the Five Dam Removal Alternative Proposed Action as described in the EIS/EIR and is not applicable to any other alternative actions described in the EIS/EIR. Exhibit F contains the Design Report prepared by Reclamation. Along with a Map of the Project, Exhibit G includes a complete list of the Hydroelectric Project exhibit drawings and a guide to which drawings have been amended either as a result of the Restoration Project modifications or for other purposes (e.g., the removal of transmission lines from the Project Boundary). On December 22, 1998, FERC issued an Order granting the Licensee s request to amend the Hydroelectric Project license to exclude non-jurisdictional transmission lines. FERC s December 22, 1998, Order became effective on February 23, FERC staff requested that the Licensee submit the revised Exhibit drawings as part of this license amendment application. Revisions to the Exhibit drawings made solely for the purpose of excluding the non-jurisdictional facilities are so noted. PRS 6

9 2 PURPOSE The purpose of the Restoration Project is to restore approximately 42 miles of Chinook salmon and steelhead habitat in the North and South Forks of Battle Creek and an additional 6 miles of habitat in their tributaries, while minimizing the loss of clean and renewable energy produced by the Hydroelectric Project. Habitat restoration will restore ecological processes that will allow safe passage for naturally produced salmonids and facilitate their growth and recovery within the restoration area and the Sacramento River (Figure PRS-1). The scale of the hydroelectric development is such that facility and operational modifications can be made to meet habitat improvement goals without excessive loss of renewable electric generation. Several naturally produced species of Chinook salmon and steelhead in the Sacramento River system have been in decline, resulting in their listing under the federal and state Endangered Species Acts (ESAs). The suitability of Battle Creek to support the recovery of several naturally occurring anadromous species is evidenced by the type of habitat it offers and the species historical use of the watershed. Battle Creek may be the only remaining stream, other than the mainstem of the Sacramento River, that can successfully sustain breeding populations of steelhead and all four runs of Chinook salmon. Specifically, the Restoration Project is intended to benefit the Central Valley spring-run Chinook salmon, state- and federally listed as threatened; the Sacramento River winterrun Chinook salmon, state- and federally listed as endangered; and the Central Valley steelhead, federally listed as threatened. Battle Creek is unique and biologically PRS 7

10 important also because it provides habitat opportunities for winter-run Chinook salmon during drought years. 3 RESTORATION PROJECT DESCRIPTION The Restoration Project includes modifications to facilities at nine dam sites located on the North Fork Battle Creek, South Fork Battle Creek, Baldwin Creek, Lower Ripley Creek and Soap Creek. As noted above, the MOU signatories have decided to implement these modifications in phases, each of which has independent ecological and environmental benefits. A general overview of the actions included in each phase is given in the following paragraphs and illustrated in Figures PRS-2, PRS-3, and PRS-4. This license amendment application seeks approval to implement Phase 1A only. During Phase 1A, fish passage improvements on North Fork Battle Creek will be achieved by installing fish screens and ladders at the North Battle Creek Feeder and Eagle Canyon Diversion Dams; installing the Eagle Canyon pipeline; removing the Wildcat Diversion Dam and appurtenant conveyance systems; and modifying the Asbury Diversion Dam. Phase 1B includes improvements on the lower South Fork Battle Creek, specifically installing a tailrace connector from Inskip to Coleman and a new Inskip bypass. PRS 8

11 During Phase 2, additional fish passage improvements on South Fork Battle Creek will be achieved by removing the Coleman, South, Lower Ripley Creek Feeder, and Soap Creek Feeder Diversion Dams; installing screens and ladders on the Inskip Diversion Dam; installing a tailrace connector from South to Inskip ; and decommissioning the South. Additional information on the Phase 1A modifications is provided in the following sections. The design details for Phase 1A are provided in Exhibit F. 3.1 North Battle Creek Feeder Diversion Dam North Battle Creek Feeder Diversion Dam is located on North Fork Battle Creek. The proposed modifications at this dam will enable salmon and steelhead to migrate unimpeded along this reach of the creek and will minimize the potential for juveniles to enter the diversion flume. The proposed modifications include: Constructing a new access road and footbridge from Volta 2. Replacing the existing sluice gate and headworks. Raising a section of the dam crest to protect new facilities during high-flow events. Installing a new pool and chute fish ladder, including a video monitoring station, orifice gates, and stop gates. Plugging the existing fish ladder and removing metalwork. Installing a new fish screen at the entrance to the diversion canal. Removing a section of the existing flume and connecting it to the new fish screen and diversion facility. Providing three slide gates, one at the headworks, one at the dam, and one at the downstream end of the fish screen. Installing instrumentation and controls to monitor the water surface elevation and regulate flow and gate operations. PRS 9

12 Upgrading electrical service to provide required power for the new facilities. 3.2 Eagle Canyon Diversion Dam Eagle Canyon Diversion Dam is located on North Fork Battle Creek. The proposed modifications will enable salmon and steelhead to migrate unimpeded along this reach of the creek and will minimize the potential for juveniles to enter the Eagle Canyon. Modifications to the spring-water collection system will increase spring-water flow to the creek. The proposed modifications include: Improving the access trail to the dam. Modifying the existing spring collection facilities to divert collected water to the creek instead of the diversion canal. Removing the existing fish ladder and canal diversion and replacing with a new headworks structure and screened diversion. Installing a new fish ladder and video monitoring station. Installing a new fish screen at the entrance to the diversion canal. Installing instrumentation and controls to monitor the water surface elevation and regulate flow and gate operations. Upgrading electrical service to provide required power for the new facilities. 3.3 Eagle Canyon Pipeline The Eagle Canyon carries water diverted from the North Fork Battle Creek. It is an unlined canal that begins at Eagle Canyon Diversion Dam and extends approximately 2.6 miles cross country to combine with Inskip. The proposed modifications will prevent potential contamination of water-borne pathogens from North Fork Battle Creek to the spring-water sources along the canal and therefore protect the Mt. Lassen Trout PRS 10

13 Farm s Jeffcoat aquaculture facility located down-gradient from the canal. The proposed modifications include: Installing a 4,500-foot, buried pipeline to bypass an open channel section of the canal. The bypassed canal section will remain in place and will continue to collect spring water and overland runoff. This flow eventually will join with the pipeline water. 3.4 Wildcat Diversion Dam Wildcat Diversion Dam is located on North Fork Battle Creek. The proposed modifications will enable salmon and steelhead to migrate unimpeded along this reach of the creek. Wildcat Diversion Dam and appurtenant canal and pipeline facilities will be removed in their entirety. 3.5 Asbury Diversion Dam Asbury Diversion Dam is located on Baldwin Creek just below the Darrah Springs Fish Hatchery. The dam diverts flows into Asbury Pump Station, which pumps water into the Coleman. The proposed modifications are designed to prevent salmon and steelhead migration above Asbury Dam to protect the fish hatchery from foreign pathogens carried by the migrating fish. The proposed modifications include: Installing an upstream fish migration barrier. Changing maintenance procedures to eliminate use of the low-level outlet. PRS 11

14 3.6 Additional Measures The Restoration Project includes a number of other measures that will enhance and ensure environmental benefits. Among these are: transferring water rights at removed diversion dams to the CDFG; dedicating the transferred water rights for instream use; creating a Water Acquisition Fund for future purchases of additional instream flow releases that may be recommended under the adaptive management process during the first 10-year period following completion of the Restoration Project; and using an Adaptive Management Fund to implement any additional modifications or refinements to the Restoration Project components developed under the Adaptive Management Plan (AMP) protocols. These measures will be implemented as far as they are applicable to Phase 1A of the Restoration Project. 4 RESTORATION PROJECT BENEFITS The proposed Restoration Project, as a whole, provides an opportunity to reestablish approximately 42 miles of prime salmon and steelhead habitat on Battle Creek and an additional 6 miles on its tributaries. Completion of Phase 1A also will meet several fishery restoration goals, independent of Phase 1B and Phase 2. Phase 1A presents an opportunity to restore approximately 13 miles of habitat from the confluence of the North and South Forks to the natural barrier about 4 miles above North Battle Creek Feeder Diversion Dam. Phase 1A actions include increased instream flow releases, release of cold spring water to adjacent stream sections, management of those instream flows, upstream and downstream fish passage, restoration of stream function to mimic the PRS 12

15 natural hydrography more closely, and adaptive management to monitor and refine restoration actions. Some of the key ecological considerations are discussed briefly in the following sections. 4.1 Instream Flow Management Modifications to instream flows are a key component of the Restoration Project as a whole. With respect to Phase 1A, minimum instream flow releases will be increased from those required in the current license throughout North Fork Battle Creek and at Asbury Diversion Dam, as outlined in the MOU. On the south fork, flows below Coleman Diversion Dam will continue as prescribed in the Interim Flow Agreement to align better with the flows outlined in the MOU. The remaining instream flow prescriptions in the MOU for the south fork will not be implemented in Phase 1A of the Restoration Project. The basis of the minimum instream flow proposals under the Restoration Project is to provide approximately 95% of the estimated habitat for the life stage (e.g., adult spawning, fry development, or juvenile rearing) determined to be the most limiting to fish production in a given stream reach. It was also recognized that during certain periods of the year, the needs of competing species can conflict. Where unavoidable habitat need conflicts occurred, the target species were prioritized based on the availability of their associated habitat in the watershed. Because their habitat is scarce, winter-run Chinook salmon was the highest priority followed by spring-run Chinook salmon, steelhead, late PRS 13

16 fall run Chinook salmon, and fall-run Chinook salmon. Additionally, passage over natural barriers was an important factor that affected the selection of an appropriate minimum flow in some stream reaches. In some cases, ensuring this passage required elevating instream flows to values higher than those considered optimal for the target life stage. Water temperatures were also an important factor in prescribing minimum instream flow releases. As discussed in the EIS/EIR, these increases in minimum instream flow releases would also significantly affect the amount of wetted habitat available. Increased wetted habitat likely would lead to corresponding increases in the production of periphyton and aquatic macroinvertebrates, which form the basis of the food chain in stream ecosystems. These organisms provide a primary food source for animal species inhabiting aquatic habitats, such as fish, reptiles, and amphibians. Aquatic insects that metamorphose into aerial and terrestrial insects would contribute to the food supply of certain insectivorous wildlife, such as willow flycatcher and several bat species. Furthermore, wildlife species that prey on fish and amphibians also would benefit from increased wetted habitat. 4.2 Fish Passage A key consideration in restoring habitat is ensuring upstream and downstream fish passage beyond both natural and artificial barriers. Accommodation of natural barrier passage was addressed during the assessment of minimum instream flow requirements. PRS 14

17 Fish passage facilities at North Battle Creek Feeder and Eagle Canyon Diversion Dams were designed as state-of-the-art installations, incorporating resource agency design criteria/guidelines for ladders and screens with geometries known to provide reliable performance (Kier Associates 1999a). The relatively low height of the dams to be passed via a fish ladder, coupled with the conservative approach to their design, is expected to provide high passage reliability. Removal of the Wildcat Diversion Dam will eliminate any concerns about fish passage at that site. Preventing the entrainment of juvenile fish in the Hydroelectric Project s remaining accessible water conveyance facilities will be accomplished by installing fish screens at the diversion points. 4.3 Restoration of Stream Function or canal outages can result in a rapid, temporary increase of flows in the North and South Forks of Battle Creek downstream of existing diversion dams. When powerhouses or canals come back on line, the drop in flow may result in the stranding of juvenile fish and amphibians. Minimizing the impacts of flow changes resulting from outages was addressed through the ramping rate prescribed in the MOU and included in this license amendment application. The ramping rate specified should improve the survival of fish and amphibians occupying transient aquatic habitat by slowly ramping down the water surface elevation in the stream. Improved survival of early fish and amphibian life stages should benefit their populations, as well as populations of species that prey on them. PRS 15

18 Taking less water from the stream channel will improve ecosystem function by providing more stable habitat for aquatic organisms to grow and reproduce and providing a needed benefit to other wildlife species that depend on them for food. Increased minimum flows also likely will result in an increase in riparian habitat along North Fork Battle Creek that is important to both aquatic and wildlife species. Increased flows in North Fork Battle Creek also will reduce the amount of water transferred to South Fork Battle Creek and therefore reduce the potential for false attraction that currently occurs in the south fork from the mixing of the two water sources. Returning spring flows in Eagle Canyon and removing the diversion at Wildcat Diversion Dam will restore transitory habitat in North Fork Battle Creek and, in part, the mainstem reach. 4.4 Adaptive Management The proposed restoration actions encompassed by Phase 1A are comprehensive and based on the best scientific information available. In addition, the MOU signatories have developed a Draft AMP (Appendix 2) that identifies specific adaptive management monitoring and research tasks that the various signatory parties have agreed to implement. Through this license amendment application, the Licensee is seeking to have the tasks it has committed to perform under the AMP incorporated into the Hydroelectric Project license. PRS 16
