EXHIBIT C - MITIGATION MONITORING PROGRAM <br />June 2023 C-10 SF Bay Fiber Optic Cables Project <br /> <br /> <br /> <br />1  The screen will be designed to allow uniform flow distribution through the <br />2 entire face of the screen during use. <br />3  If the screen is self-cleaning, the specific screen intake velocity will be <br />4 0.2 feet per second, which is the protection velocity for delta smelt <br />5 (Hypomesus transpacificus) and is also considered protective of longfin <br />6 smelt. If the screen is not self-cleaning, the screen will be designed so that <br />7 the approach velocity is one fourth of the self-cleaning approach velocity <br />8 (0.05 feet per second). For non-self-cleaning screens, the frequency of <br />9 cleaning will be such that flow is not impaired and approach velocity is <br />10 not exceeded. A cleaning frequency of once per 5 minutes is considered <br />11 appropriate. <br />12  The required screen area in square feet will be determined by dividing the <br />13 maximum diverted flow (cubic feet per second) by the allowable <br />14 approach velocity (feet per second) to get square feet of screen area <br />15 needed. <br />16  The screen surface will have a minimum open area of 27 percent, but <br />17 open areas of 40 percent or greater are recommended. Round openings <br />18 will not exceed 5/32 inch (3.96 millimeter). Square openings will not <br />19 exceed 5/32 inch (3.96 millimeters) diagonally. Slotted openings will not <br />20 exceed 0.0689 inch (1.75 millimeters). <br />21  Screens can be constructed of any rigid material that allows water <br />22 passage but excludes fish. Stainless steel is recommended to reduce <br />23 corrosion-associated clogging. No sharp edges or projections that could <br />24 harm fish will be present. The largest screen open area possible for the <br />25 project should be used. If anti-fouling materials are used, they should not <br />26 be deleterious to fish or other wildlife. <br />27  The intake with the screen cover will be placed in the deepest area of <br />28 water possible for the jet sled location. <br />29  The plans and design of the fish screen showing the applicable screening <br />30 criteria will be provided to the California Department of Fish and Wildlife <br />31 for approval. <br /> <br />32 Location: Marine Project area <br />33 Monitoring/Reporting Action: Equipment design specifications. Approval <br />34 required from California Department of Fish and Wildlife. <br />35 Effectiveness Criteria: Implementation of this MM will reduce the potential for <br />36 longfin smelt to be impacted during Project activities. <br />37 Responsible Party: Applicant <br />DocuSign Envelope ID: 8D8CF2E2-DF6D-4A11-B610-2B1544DD7C30
