9.4 TURBINE INTAKE SCREENS(Develop New Designs, Complete Tests, Report to Council: January 1989)9.41103(d)Bonneville shall fund studies to determine the effectiveness ofnew designs for turbine intake screens <strong>and</strong> their suitability forapplication at small hydroelectric projects.ACTION ITEM ACTIVITY SUMMARY:Objectives:To develop a new st<strong>and</strong>ard <strong>fish</strong> screen that is biologically efficient<strong>and</strong> cost-effective for hydro developers.Background <strong>and</strong> Progress to Date:Plans:ProjectsInstallation <strong>and</strong> maintenance of currently available screening systemsare expensive <strong>and</strong> must be tailored to the site. Most present screensystems have not been tested sufficiently to be characterized asproven. Existing designs <strong>and</strong> new designs must be evaluated todetermine which designs are biologically <strong>and</strong> economically efficient.The suitability of screen designs for application at smallhydroelectric facilities must also be determined. The intent is toprovide acceptable <strong>fish</strong> screen designs with general applicability forregional hydropower developers.Presently deferred, since BPA's adoption of Protected Areas in itsLong-Term Intertie Access Policy provides protection for <strong>fish</strong>investments through denying access to the Pacific Northwest-PacificSouthwest Intertie to any new hydroelectric projects located indesignated Protected Areas of the Columbia River Basin.No BPA-funded projects.2 5 1
