FINAL for 10/16/06 Meeting MPWMD Comparative Matrix -- Part I-A, Desalination Projects
DECISION ELEMENT COASTAL WATER PROJECT        NORTH MONTEREY COUNTY DESALINATION PROJECT                        LONG-TERM WATER SUPPLY PROJECT (Sand City Desal)
PROPONENT/SPONSOR California American Water Pajaro/Sunny Mesa CSD MPWMD
PROJECT DESCRIPTION Moss Landing desal plant assumes use of Duke Energy site and intake/outfall.  Includes desal conveyance system comprised of transmission main, terminal reservoir, and pump stations; and ASR facilities to store CR (or desalinated) water in Seaside Basin. PEA analyzes Proposed Project and five alternatives (see Line 60).  Proposed Project yield is 11,730 AFY. Desal plant at National Refractories site; prefer use of Duke Energy wastewater as source (existing intake as backup) with existing outfall.  Includes energy recovery; possible 30-ac solar energy. Current focus on regional plant, including P/SM service area; willing to expand to serve other areas. No ASR is planned, but could be combined with MPWMD ASR project. Desal plant at Sand City with potential intake and outfall locations from Seaside State Beach to coastal Fort Ord.  HDD well technology needed to achieve 8,409 AF yield goal; brine disposal via MRWPCA outfall likely needed.  Could be combined with MPWMD ASR project.
Pilot Project Approvals expected by end of 2006; install early 2007; operate for one year via agreement with LS Power.   Approvals expected iby end of 2006 based on approved Encina plant design; plan to operate 4 yrs.; managed by Kennedy/Jenks expert  None planned currently, but will be required by DHS
PROJECT YIELD Actual yield based on commitments of purveyor customers Actual yield based on commitments of purveyor customers 8,409 AFY yield goal; possibly 11,000 AFY (uncertain)
Comply with Order 95-10? Water for Seaside Basin? Yes, 10,730 AFY assumed for Project and alternatives.  1,000 AFY slated to replace Cal-Am use in Seaside Basin. Yes, 10,730 AFY assumed.  Up to 2,700 AF to address gap between current production and sustainable yield estimate in Seaside Basin. Yield falls short of 10,730 AFY unless expanded or combined with another project.  No yield to address Seaside Basin.
Future Mont. Penin. Needs? Regional Alt includes 3,572 AFY for jurisdictions within CAW service area as previously identified by MPWMD and jurisdictions. Water for growth not currently contemplated. Current project goal is legalizing existing use (11,285 AFY from CR and 3,500 AFY from Seaside assumed).   Water for growth not contemplated.
Future Non-MP Needs Regional Alternative lists 4,970 AFY for MCWD/NorCo as amended by particpants.  North Marina Alt could also be sized to meet regional needs. Up to 11,230 AF to address known overdraft in areas now within P/SM service area None 
TOTAL YIELD 11,730 AFY for Proposed Project; 20,272 AFY for Regional Alternative (or North Marina Alt). 20,000-22,400 AFY (20 MGD project, capable of producing up to 22,400 AFY - 20,930 AFY demand identified) 8,409 AFY.  Project could potentially be expanded to 11,000 AFY - permitting and feasibility are uncertain.
Yield Phasing to Mont Penin 11,730 AFY is Proposed Project amount.  Oversized Pipeline Alt or Regional Alt could facilitate incremental future supply above 11,730 AFY.     Phasing based on demand; assume 10,730 AF plus amound needed for Seaside first No phasing

COST TO PENINSULA
Share of total project cost 100% of Proposed Project costs are for CAW Peninsula customers; Regional Alt would rely on prorata share of participation.  Cost of water based on contract volume (capacity+annual usage charges); separate charge for pipelines and pumping facilities.   Entire cost to be paid by Peninsula consumers. 
How share determined See line 23 See line 23 N/A
Cost sharing of existing vs. future Cal-Am ratepayers See CPCN application; David Stephenson testimony Future capacity cost based on construction and transmission New users pay connection fee similar to current system
Cost of Water ($/AF) Proposed Project is $1,725/AF delivered to Peninsula customers ($1,000/AF for desal plant, pumps, pipes and storage; $150/AF for ASR; $550/AF for O&M). Includes lease of desal site.  Regional Alternative would be $1,600/AF for CAW customers.                             Based on 10% contingencies - B-E/GEI Consultants recommend 25% contingencies. B-E/GEI evaluated only the desalination component of the project, and not the ASR component.

Local Agencies All affected cities and jurisdictions for encroachment and construction permits; includes MLHD   Similar to CWP; jurisdictions may vary; MLHD (?)  Construction and use permits within affected jurisdictions
SITE CONTROL
Confirmed site? Moss Landing Power Plant planned for pilot plant.  "Duke East" site evaluated in PEA as preferred site.   Confirmed site for pilot project.  Lease agreement signed with owner of Natl Refractory site.  Potential use of LS Power discharge rather than own intake; will use own outfall.   Sites and alternatives identified; agreements with owners are needed, including MRWPCA for use of regional outfall.
Alternative sites and projects? Moss Landing scenario in PEA evaluates Granite Rock and Natl Refractories sites.                              Five project alternatives in PEA include: (1) Regional Alt with 20,272 AFY yield; (2) Over-sized Pipeline Alt with larger source and transmission pipelines to enable future supply increases; (3) HDD Intake Alt using HDD intake wells near MLPP as feedwater supply rather than Duke intake; (4) North Marina Alt, which locates plant in Armstrong Ranch area with HDD intake and MLPP outfall for brine; and (5) No Project Alt, comprised of existing conservation efforts.  No alternative to National Refractories site needed.  EIR will identify project alternatives.  Several locations for desalination plant, seawater collectors and brine disposal via HDD and MRWPCA outfall evaluated in BRDEIR, along with other project alternatives.
OPERATIONS/OTHER
Technical, Managerial and Financial Capabilities (TMF) to meet DHS standards Cal-Am has extensive TMF capabilities and current certifications to own/operate water systems. Over 39,000 customers in Monterey County P/SM has current TMF certification by DHS. Planned enhancement for desal project includes expanded board and staff; plan to outsource engineering (K/J), legal, development, contract, admin, construction, management; Poseidon is "Exclusive Management Agent" in current agreerment. Assume certified entity would operate plant in coordination with Cal-Am system, with MPWMD oversight.
Back-up; water production interruptions (e.g., power or intake water) CWP design is consistent w/ Duke operations; forebay, storage tanks and ASR as backup; also other Cal-Am sources in Seaside and CR. Own inake is backup supply if MLPP  discharge water not available; refurbishing seawater tanks with 11-day supply; generators and onsite solar, if feasible.  Notes County Ordinance requires back-up supply.  Redundant plant design; back-up generators; ASR source
PROJECT PARTICIPANTS  
Overview CAW willing to participate in public/private partnerships and regional governance formation.  Proposed project is geared toward existing CAW customers. Regional Alternative includes cities and areas within MPWMD, MoCo, MCWD, Castroville WD and Moss Landing; pending further study and action by entities. Focus on regional plant, including P/SM needs; willing to expand plant to meet needs of others such as FORA, MCWD and Monterey Peninsula. Funded by MPWMD via methods allowed by MPWMD Law; possible public-private partnership or JPA.  
MPWMD participation MPWMD and CAW executed April 2006 Management and Operations Agreement regarding ASR component. No approvals to date.  P/SM Board authorized JPA with MPWMD in 2004; MPWMD declined offer at that time. MPWMD currently envisioned as sole sponsor.
