r. AICin-water work associated with the east tidal cut(installation of the inlet/outlet structures)shall <br /> be conducted between August.I-and October 1; which is within the seasonal work.window <br /> suggested by USFWS(August.1 to November-1)to minimize effects to Delta smelt. <br /> E s. Measures consistent with the current Caltrans' Canstructiori BMPs Monual'(in&iding the�Storm <br /> water Pollution Prevention Plan [SWPPP] and Water pollution Control'program 000P).Manuals <br /> [http://www.dot.c0'gov/hq/construc/stotreiwater/CSBMPM 303 Flnal.pdf]) shallbe'iniplemente'd <br /> to minimize effects to fish (e.g., siltation, etc.) during construction. <br /> t. All in-water work associated with the east tidal cut(installation of inlet/outlet structures) shat1 be <br /> conducted between August 1=and October 1, which+is within the seasonal work window <br /> suggested by NOAA Fisheries (June 1 to October 31) to minimize effects to migeating-,salmonid s. <br /> u. Measures consistent with the current Caltrans' Construction BMPs Manual (including the Storm <br /> Water Pollution Prevention Plan [SWPPP] and Water Pollution Control Program [WPCP] Manuals <br /> [http://www.dot.ca.gov/hq/construclstormwater/CSBMPM_303—Final.pdq) shall be implemented <br /> to minimize effects to anadromous salmonids (e.g., siltation, etc.) during construction. <br /> v. Prior to issuance of a grading permit or other authorization to proceed with project construction, <br /> the project proponent shall obtain any necessary permits, agreements, etc. from the U. S. Army <br /> Corps of Engineers, Regional Water Quality Control Board, and the California Department of Fish <br /> and Game. <br /> w. All in-water work within the irrigation ditches and White Slough shall be conducted between <br /> August 1 and October 1, which is within the seasonal work window suggested by NOAA Fisheries <br /> (June 1 to October 31)to minimize effects to migrating salmonids. <br /> x. Measures consistent with the current Caltrans' Construction BMPs Manual (including the Storm <br /> Water Pollution Prevention Plan [SWPPP]and Water Pollution Control Program [WPCP] Manuals <br /> [http://www.dot.ca.gov/hq/construc/stormwater/CSBMPM_303_Final.pdf]) shall be implemented <br /> to minimize effects to Waters of the U. S. (e.g., siltation) during construction. <br /> 3. REGIONAL WATER QUALITY CONTROL BOARD <br /> a. Prior to construction, a Waste Discharge Requirement(WDR) Permit and an NPDES General <br /> Construction Activity Stormwater Permit shall be obtained. If a Section 404 permit is also required <br /> from the Army Corps of Engineers for the outfall structure, and a Section 401 Water Quality <br /> Certification will be required through the RWQCB. Prior to construction a Storm Water Pollution <br /> Prevention Plan (SWPPP) shall also be prepared to reduce potential impacts to surface water <br /> quality through the construction and operation of the project. The SWPPP would act as the <br /> overall program document designed to provide measures to mitigate potential water quality <br /> impacts associated with the implementation and operation of the proposed project. The SWPPP <br /> shall include: <br /> b. Specific and detailed BMPs designed to mitigate construction-related pollutants. Specific and <br /> k detailed BMPs included in the SWPPP shall include practices to minimize the contact of <br /> construction materials, equipment, and maintenance supplies (e.g., fuels, lubricants, paints, <br /> solvents, adhesives)with storm water. The SWPPP shall specify properly designed centralized <br /> storage areas that keep these materials out of the rain. <br /> Conditions of Approval - 5 - PA-0700074 <br />
