Background on EIR/EIS

• Jones & Stokes Associates retained in March 2002 to prepare EIR/EIS in compliance with CEQA/NEPA;

• Multi-purpose document will evaluate range of alternatives for use in decision-making by MPWMD and other agencies;

• Evaluate three production targets (15,285, 17,641 and 18,941 AF/yr).

6


Alternatives to be Studied

• Carmel River Dam (Cal-Am proposal),• Local desalination, • Aquifer storage and recovery (ASR),• Reclaimed wastewater,• Storm water reuse, • Off-stream storage,• Additional water rights, • Plan B (level of detail to be determined).

7


Time Line Graphic

• Provides overview of CEQA/NEPA and other relevant processes such as SWRCB water rights and CPUC approvals;

• Phase 1, identify alternatives-- in progress; delayed due to lack of access to technical data supporting CPUC’s Plan B Final Report;

• Phase 2, complete Draft EIR-- on hold until Cal-Am plans and lead agency issues are clarified.

8


Board Direction in Aug-Sept 02

• Complete Phase 1 engineering studies of alternatives; identify project combinations and sizes to meet production targets;

• Hold off on Phase 2 EIR preparation until Cal-Am plans are clear and lead agency issues with CPUC are confirmed;

• Prepare Carmel River Flow Threshold Report within 90 days.

9


Carmel River Flow Threshold Report

• Review existing information about river flow and habitat needs for Carmel River steelhead, red-legged frogs, riparian habitat and insect food sources;

• Identify conflicts and unknowns;

• Assess diversions that could be taken from the river without harming ecosystem;

10


Threshold Report, continued

• Use in EIR to set “standards of significance” to evaluate impact of water rights applications and water supply alternatives (significant or not?);

• Use in future watershed management to support self-sustaining ecosystem with minimal human intervention.

11


MPWMD Action in Aug-Oct 02

• Held two Board meetings on policy issues raised by comments on proposed EIR/EIS;

• Received and reviewed Plan B Final Report; developed costs to fully evaluate;

• Updated District CVSIM computer model; • Obtained Cal-Am hydraulic model;• Developed initial alternative combinations and

sizes based on NMFS recommended flows and water production targets;

12


MPWMD Action, continued

• Consolidated data and began assessment for Carmel River Flow Threshold Report;

• Met with SWRCB, CPUC and FORA regarding EIR/EIS and water rights issues;

• Received responses from Cal-Am and U.S. Army regarding EIR/EIS process;

• Continued participation in San Clemente Dam environmental review;

13


MPWMD Action, continued

• Continued ASR testing in Seaside Basin, focusing on recovery of injected water;

• Completed Phase III Hydrogeologic Update of Laguna Seca Subarea;

• Began Seaside Basin Groundwater Management Plan consultant search;

• Helped MCWD with reclamation project EIR;• Responded to comments on District water rights

applications.

14


Engineering Analysis

• Progress slowed due to CPUC restrictions on data supporting Plan B Final Report;

• Developed initial project combinations and sizes; larger local desal project than currently envisioned is needed to meet higher production targets;

• Finalizing constraints analysis to identify largest feasible project sizes;

15


Engineering Analysis, continued

• Refining yield estimates based on constraints analysis;

• Alternative pipeline alignments and well sites/spacing for large ASR project;

• Updated reclaimed water yields based on recent information for Pebble Beach and PCA/MCWD projects;

• Use Cal-Am hydraulic model and system map to determine best facility locations.

16


Meetings of Interest

• SWRCB (Sept 02)– Discussed comments on EIR and District water rights applications. SWRCB provided guidance on environmental analysis and “no project” definition.

• CPUC (Sept 02)– Discussed data access and lead agency role. No decision on lead agency until Cal-Am clarifies its proposed project; data request under CPUC review.

17


Meetings of Interest, continued

• FORA (Oct 02)-- review role of FORA and other entities in approval of infrastructure associated with project alternatives on former Fort Ord. Discussed regional water supply concepts.

• Trying to set meeting with City of Seaside about ASR injection well locations.

18


Next Steps through Dec. 02

• Await Cal-Am determination on proposed water project (dam vs. Plan B);

• Discuss lead agency issues with CPUC;• Complete Flow Threshold Report;• Complete engineering evaluations; present

update at November 14 workshop;• Continue water rights process; respond to

protests and comments.

19


Keeping Informed

• Quarterly update meetings • Board workshops (next: November 14 at 7 PM at

District conference room)• Monthly report in MPWMD Board packet• Expanded quarterly report in Board packet• Website, “General Manager Weekly Summary”• Website, “Water Project EIR 2002-2003” • www.mpwmd.dst.ca.us
