WWTP Planning Process Treasure Island Development Authority

Permits Agency Permit   NPDES or WDR for discharge water quality RWQCB – Regional Water Quality Control Board  Establishes required performance criteria for WWTP operation   BCDC -- Bay Conservation Outfall, if required and Development Commission   USACOE -- U.S. Army Corps Construction permits for wastewater facilities discharging to Waters of the U.S. of Engineers   Environmental Permits required for USFWS, F&G -- U.S. Fish & Wastewater Treatment Facility, including Wildlife Service, California WWTP and Outfall and Recycled Water Facility, Dept of Fish & Game, Coastal if discharging to Waters of the U.S. Conservancy, etc. Treasure Island Development Authority

Phases and Elements of WWTP Planning 1. Pre- Solicitation Phase a. Finalize TIDA-SFPUC MOU b. Confirm Study Area c. Determine Regulatory Objectives – Preliminary RWQCB Permit d. Evaluate and Determine Procurement Method 2. Solicitation Phase a. Request for Bids – Design or Design/Build Team b. SFPUC – TIDA Steering Committee 3. Implementation Phase a. Design b. Construct c. Operate New Plant d. Decommission Old Plant Treasure Island Development Authority

New WWTP – Determine Needs and Approach Study: Determine  treatment process, footprint, delivery method Delivery Method: Design  and bid (or D / B ?) contract to construct new plant Target: Operational by  2022 Funding: SFPUC has  budgeted $63M over 3 years beginning FY 16/17 Treasure Island Development Authority

Draft MOU Between SFPUC and TIDA Treasure Island Development Authority

Key Elements of the WWTP MOU Between SFPUC and TIDA  Responsibility of Parties  Design and Construct  Ownership  Operations & Maintenance  Permits  Capacity Requirements  Average Dry Weather Flow (ADWF)  Peak Dry Weather Flow (PDWF)  Peak Wet Weather Flow (PWWF)  Recycled Water Flow  Conditions Precedent to Construction  Site Preparation and delivery  Regulatory and Environmental Permit Approvals  Real Property Considerations Treasure Island Development Authority

SFPUC MOU for WWTP DDA calls for TIDA and SFPUC to negotiate a Memorandum of Understanding (" SFPUC MOU ") that includes: (i) the terms upon which SFPUC will provide a new or upgraded wastewater treatment plant for which the SFPUC will be responsible for the financing and construction; (ii) a process for SFPUC to provide a service plan in response to each Major Phase Application, including milestones such as target dates for planning, design, regulatory approvals and entitlements and permits necessary to meet the proposed service plan; (iii) a meet and confer process among the Authority, Master Developer and the SFPUC if the SFPUC fails to meet the milestones in the SFPUC MOU (iv)a meet and confer process among the Authority, Master Developer and the SFPUC if timing of the WWTP interferes with Subdivision Map or Building Permit approvals. 16 Treasure Island Development Authority
