8/7/2019 LETTER OF INTENT WITH CITY OF LOS ANGELES • In place July 2019 • Intent – Provides a basis for collaboration between the City’s Hyperion Program and Metropolitan’s Regional Program – Supports development of a formal Memorandum of Understanding between the parties • Benefits – Improves potential for integration between two systems – Allows for coordination in planning and regulatory process – Reduces potential conflicts/duplication of activities 11 ENVIRONMENTAL REVIEW PROCESS 6
8/7/2019 APPROACHES TO THE CEQA PROCESS • Programmatic EIR (PEIR) provides high ‐ level analysis of effects of a multi ‐ year, multi ‐ phase program • Project ‐ specific tiered documents – can be prepared as part of the initial PEIR, or at later date – conducted when additional design and site information is available 13 TIERED PROCESS Programmatic EIR Initial Pipeline Project Tiered Project ‐ specific Document 14 7
8/7/2019 IMPLEMENTATION OPTIONS THREE OPTIONS Traditional Programmatic EIR (PEIR) Option Everything above plus: Accelerated • Tiered project ‐ level document for Construction 3.5 ‐ mile pipeline Accelerated Everything above plus: Water • Initial AWT plant (approx. 20 mgd) • Conveyance to West Coast Basin Delivery 16 8
