3 15048734.1 4. Mountain Tunnel Flow Control Facility (FCF) Project means construction of a FCF at the downstream end of Mountain Tunnel to reduce lining damage by eliminating the daily cycling between open channel and pressurized flow conditions inside the tunnel, and to allow access to the tunnel when the elevation of the water surface in Priest Reservoir is higher than the elevation of Priest Portal. The project consists of constructing a bypass tunnel, a FCF access shaft and related appurtenances, installing flow control valves and associated mechanical, electrical, and instrumentation as well as construction of a new Mountain Tunnel adit at Priest Reservoir, and a new access road to the FCF. The bypass will be fully steel lined to accommodate higher operating pressures, and a concrete plug will be constructed at the upstream end where water is diverted into the FCF. Project capital costs include costs incurred in FY 2017-18 and subsequent fiscal years until the project is complete. 5. Kirkwood Penstock Project means repair, rehabilitation or replacement of the penstock between the Canyon Portal Valve House and the outside of the northern wall of the Kirkwood Powerhouse. The Joint classification for this project would exclude valves, electronic controls and other appurtenances needed for power operations but not for delivery of water to the Bay Area. Project capital costs include costs incurred in FY 2009-10 and subsequent fiscal years until the project is complete. 6. Moccasin Dam Interim Repairs means repairs and improvements related to damage caused by the March 22, 2018 storm with the goal of returning the reservoir to service at a restricted water pool elevation. The interim measures include repairs and improvements to the Moccasin Creek Diversion Dam and Bypass, Moccasin Reservoir, access and automation improvements at Gate No. 3 Tower, the Lower Moccasin Dam Auxiliary Spillway, and the downstream channel of Moccasin Creek. Project capital costs include costs incurred in FY 2017-18 and subsequent fiscal years until the project is complete. 7. Moccasin Dam Long-Term Improvements means upgrading the Moccasin Reservoir facilities to meet long-term operational and dam safety needs, including the Lower Moccasin Dam, Moccasin Creek Diversion Dam, spillways, outlet works, and other appurtenant facilities, excluding the Moccasin Low Head Hydropower Plant and appurtenances. The work consists of repairs and upgrades to restore the capability to accommodate changes in flow associated with water delivery and power generation, provide hydraulic control for delivery of water to the Bay Area, permit the discharge of excess water downstream to Don Pedro Reservoir, and satisfy State regulatory requirements and guidelines. The Joint classification for this project would include all work, regardless of whether or not specific elements are required by the State of California. Project capital costs include costs incurred in FY 2017-18 and subsequent fiscal years until project is complete. 8. Moccasin Penstock Project means the repair, rehabilitation or replacement of the Moccasin Penstocks to ensure reliable water delivery to the Bay Area and support power generation at Moccasin Powerhouse. Project facilities would extend from the western end of the Moccasin Power Tunnel to the eastern wall of the Moccasin Powerhouse. The Joint classification for this project would exclude valves, electronic controls and other appurtenances needed for power operations but not for delivery of water to the Bay Area. Project capital costs include costs incurred in FY 2009-10 and subsequent fiscal years until the project is complete.
