RESPONSES TO RECOMMENDATIONS of the U.S. Fish and Wildlife Service in theFinal Coordination Act Report.1. That the design of the powerhouse allow the release of regulatedflows to Allison Creek throught the tailrace and excess flows to PortValdez through the other tailrace.Response: The selected plan includes a two tailrace system which wouldallow regulated flows to both Allison Creek and Port Valdez.2. That flows from the powerhouse tailrace to Port Valdez be dischargedsubtida11y to at least -10 feet MLLW from June through September.Response: During the advanced engineering and design phase, studies willbe conducted to determine stream temperatures with project operation. Ifthese studies indicate the stream temperature during the spawning wouldbe below the critical level and all the project discharge could not bedischarged into Allison Creek during spawning, mitigative measures, suchas a subtidal outlet would probao1y be employed.3. That the proposed start-up of project operation affecting the naturalflows in Allison Creek occur in an even year.Response: The initial drawdown for securing the tap and the placement oftrash racks would probably occur during the winter months when flows intothe Port Valdez tai1ace and would have no impacts on the incubating eggswithin Allison Creek and the intertidal area. Project operation wouldprobably occur with the refilling of the lake the same year as thedrawdown. It would be impossible at this time to insure project startupwould occur in an even year.4. That the timing of proposed construction activities in or on thebanks of Allison Creek be coordinated with the FWS, NMFS, and the ADF&G.Response: This recommendation will be included in the stipulations tothe contractor.5. That streambanks be restored to preproject integrity during theconstruction season in which they are damaged and debris or vegetation bekept out of streams.Response:Refer to response to number four.6. That any structures placed in or across streams be removed during thesame construction season.Response:Refer to response to number four.
