DDA & Related Documents

Document Requirements or Purpose

• EDC MOA

TIDA and Navy Agreement: Navy keeps (E) WWTP through 2020

• DDA INFRASTRUCTURE

PLAN

TIDA and TICD (Developer) Agreement (Section 7.10): contemplates that the SFPUC will provide a new or upgraded wastewater treatment plant as needed to meet the flow and treatment requirements of the Project projected for each Major Phase; TICD prepares pad; TIDA readies land; SFPUC builds (N) Plant and deconstructs (E) Plant when ready

• Draft PUC-TIDA WWTP

MOU

TIDA and SFPUC Agreement: Provides parameters and responsibilities for operating (E) WWTP and designing and constructing (N) Plant

• EIR

WWTP parcel is described as 4-6 acres (not to exceed 6 acres)

WWTP Planning Process

Treasure Island Development Authority

Agency Permit

• RWQCB – Regional Water

Quality Control Board

• NPDES or WDR for discharge water quality
• Establishes required performance criteria for

WWTP operation

• BCDC -- Bay Conservation

and Development Commission

• Outfall, if required
• USACOE -- U.S. Army Corps
• f Engineers
• Construction permits for wastewater facilities

discharging to Waters of the U.S.

• USFWS, F&G -- U.S. Fish &

Wildlife Service, California Dept of Fish & Game, Coastal Conservancy, etc.

• Environmental Permits required for

Wastewater Treatment Facility, including WWTP and Outfall and Recycled Water Facility, if discharging to Waters of the U.S.

Permits

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



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

New WWTP – Determine Needs and Approach

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

• f 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.
