| FINAL for 9/18/06 Meeting | MPWMD Comparative Matrix -- Part I, Desalination | ||||
| 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 | Sep 05 approval expected from CCC, RWQCB and Monterey County; install in Fall 05; operate in Jan 06 for one year via agreement with Duke Energy. | Permits expected in Nov 05 based on approved Encina design; plan to operate 4 yrs.; managed by K/J 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 identifies 3,572 AFY for jurisdictions in CAW as amended by participants. North Marina Alt could also be sized to meet these needs. | 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) | ||
| 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. | ||

| 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 | |||||
