HYBRID REGIONAL PLAN
Because of requirements to reduce water taken from the Carmel River, the California Public Utilities Commission (CPUC) ordered California American (Cal Am), the Peninsula’s major water purveyor, to develop a water supply project. CalAm’s proposal, known as the Coastal Water Project (CWP), focuses on a seawater desalination plant either at Moss Landing or North Marina. A draft environmental impact report (DEIR) evaluated the impacts of plants at these locations along with an alternative developed by local agencies referred to as the Regional Plan.
Each of the three alternatives has serious pitfalls, although the “regional alternative” does propose a cooperative approach. In the interests of avoiding the pitfalls and expediting a real water supply solution, a group of community-based, non-profit, non-governmental organizations developed the Hybrid Regional Plan.
The Hybrid Regional Plan is NOT a new approach. Rather, it is a mix of the best elements evaluated in the CWP DEIR, as well as some projects already in place. As discussed below, the Hybrid Regional Plan
To-date, the Hybrid Regional Plan approach has been endorsed by the League of Women Voters of the Monterey Peninsula, the Carmel Valley Association, the Ventana Chapter of the Sierra Club, LandWatch Monterey County and the Prunedale Neighbors Group. It represents a milestone in community agreement at the grass-roots level, since many of these organizations have never endorsed previous water supply proposals.
The Monterey Peninsula has serious water supply problems. California American (CalAm), which is the major water purveyor for the area, is under State order (SWRCB Order 95-10) to significantly reduce extractions from the Carmel River. Additionally, the Seaside Basin has been recently adjudicated resulting in a court order to reduce water pumping from the Basin.
In response to these issues, the California Public Utilities Commission (CPUC), which regulates private utilities such as CalAm, ordered the utility to develop a water supply proposal to meet these regulatory requirements. CalAm’s proposal, known as the Coastal Water Project, includes two alternatives which primarily rely on desalination of sea water. The Moss Landing project is for 10,000 acre-feet per year (AFY); it would desalinate cooling water from the Moss Landing Power Plant. The North Marina project is for 11,000 AFY; it would extract water from Monterey Bay using slant well technology. Both of these projects are intended to meet regulatory requirements and would not provide water for growth.
Both desalination proposals rely primarily on the most expensive source of water. If sited at Moss Landing, the Peninsula’s water supply would become inextricably linked to outdated technology for the production of electricity.
As part of the development process for the Coastal Water Project, a group of interested agencies, organizations and individuals were convened to develop a third alternative to be addressed in the environmental impact report prepared for the Coastal Water Project. The group initially was known as the Regional Plenary Oversight Group (REPOG) and is now called Water for Monterey County. It met over many months to develop a regional program that would be undertaken by local and regional agencies in Monterey County. The Regional Plan was developed by staff of the Marina Coast Water District (MCWD) and Monterey County Water Resource Agency (MCWRA) with assistance from an engineering consultant. The individuals and groups who participated in the REPOG meetings had opportunities to comment on the Regional Plan as it was developed; however, the group did not vote on the Regional Plan submitted to the CPUC for environmental review.
The Regional Plan described in the Draft Environmental Impact Report (DEIR) has two phases. Phase I projects would produce a total of 15,200 AFY. Phase I includes
Of the15,200 AFY produced in Phase I, 12,500 AFY is allocated for the Monterey Peninsula and 2,700 AFY for Marina/Fort Ord. Phase I projects are intended to only provide water for growth for Marina/Fort Ord.
Phase II would expand water supplies to meet development included in the general plans of Monterey Peninsula cities, unincorporated areas, and Marina/Fort Ord. Phase II is also intended to address North Monterey County water supply problems. Phase II projects include
Memoranda of Understanding implementing feasibility studies for Phase I projects have been signed by MCWD, MRWPCA and the County of Monterey.
The environmental impacts of these proposals are presented in the DEIR prepared for the Coastal Water Project. The Final EIR (FEIR), which will respond to extensive public comments on the DEIR, is scheduled for release in the fall of 2009. In the interim, an Administrative Law Judge for the CPUC will hold hearings and receive testimony on other aspects of the CWP including costs and feasibility of implementation.
REASONS FOR DEVELOPING THE HYBRID REGIONAL PLAN
Priority Should be on Meeting the Monterey Peninsula’s Urgent Water Needs. Because of the Regional Plan’s focus on extracting water from the Salinas Valley Groundwater Basin (SVWB) and the Salinas River, implementation of the Regional Plan will likely delay, perhaps for years, urgently needed solutions to the Monterey Peninsula’s critical water problems. The impacts of extracting water from the degraded SVWB have not been adequately addressed and require additional environmental review. Water rights of the agencies proposing to extract water from the basin have not been established. Litigation by affected property owners with land overlying the SVWB is almost certain.
Additionally, elements in the Regional Plan fluctuate from day to day. As Curtis Weeks, General Manager of the MCWRA, says, the Regional Plan is “squishy.” For example, during MOU negotiations to implement the Regional Plan, estimates for the desalination plant ranged from 14,600 AFY for Phase I to 21,300 AFY for Phase II. This is significantly more than the 10,000 AFY desalination facility originally proposed and evaluated in the Coast Water Project DEIR. Furthermore, when the ratio of source water to desalinated water is considered (a ratio of 2:1), the Regional Plan could extract anywhere from 20,000 AFY to 42,600 AFY from the degraded Salinas Basin and Monterey Bay. These extractions, if ever allowed, would produce 10,000 AFY to 21,300 AFY per year of potable water for use on the Monterey Peninsula, Marina and Fort Ord.
Even accepting the statement that only 15% of the water would be from the SVGB (this percentage has not been verified) with the rest coming from Monterey Bay, extracted water could range between 3,000 AFY and 6,390 AFY. The larger amounts have not been evaluated and would take additional environmental review to determine their feasibility and impacts on the SVGB.
The viability of the Regional Plan’s North Marina desalination project is threatened by potentially extensive delays caused by litigation which could last for years as well as by the need for additional environmental review. Instead, the focus should be on meeting the urgent water needs of the Monterey Peninsula which the Hybrid Regional Plan addresses.
Lost Focus. The original goal of the Regional Plan was to develop a sustainable water supply. During the REPOG process, the emphasis shifted away from sustainability and conservation in favor of a primary focus on a very large and costly desalination plant.
The Hybrid Regional Plan, detailed below, reintroduces the original goal of developing a sustainable water supply.
Lack of Representation for Monterey Peninsula Ratepayers and Voters. The Monterey Peninsula Water Management District which is the agency with management responsibility for water on the Monterey Peninsula is not included as a lead or co-lead agency for implementing the Regional Plan. This agency is elected and responsible to the voters on the Monterey Peninsula. As proposed, the major source of future water supplies under the Regional Plan would be undertaken by the Marina Coast Water District and Monterey County Water Resources Agency, disenfranchising Monterey Peninsula ratepayers and voters. In contrast, the Hybrid Regional Plan assures representation of Monterey Peninsula Ratepayers and Voters.
HYBRID REGIONAL PLAN
Phase I of the Hybrid Regional Plan would provide 2,700 AFY for Marina/Fort Ord and 10,300 AFY for the Monterey Peninsula. The amount of water for Marina/Fort Ord is the amount allocated in Phase I of the Regional Plan. Based on data in the May 7, 2009 Administrative Law Judge draft opinion, 9,000 AFY is needed to meet regulatory requirements for the Monterey Peninsula; data in the DEIR show that 10,272 (10,300 rounded) AFY is needed. The three alternatives described above provide 12,500 AFY for the Monterey Peninsula which includes an additional 2,200 AFY mostly for drought reserve and to meet future demands on the Seaside Basin. Based on information in the DEIR, there are no regulatory provisions limiting use of that water for future needs including drought reserve. The Hybrid Regional Plan focuses on meeting Regulatory Requirements first.
Regional Approach with Assurances of Representation of Monterey Peninsula Ratepayers and Voters
The Hybrid Regional Plan proposes that the MPWMD and MCWD be co-lead agencies to implement the Plan. Under a joint-powers agreement, these agencies would design and implement the desalination plant and work with the MRWPCA to implement the Groundwater Replenishment Program which requires participation of a water district. CalAm would be responsible for reducing unaccounted for water, and CalAm and MPWMD would continue implementation of ASR.
Source Water from Slant Wells into Monterey Bay
Source water for the desalination plant would be from the Monterey Bay using slant well technology addressed in the DEIR for the CWP. The MPWMD is currently working on a desalination facility using this technology. The well location would be in North Marina or southern locations. Consideration should also be given to working with Sand City to expand its facility. This location was previously considered by the MPWMD for a desalination project that could produce up to 6,000 AFY. This approach would facilitate development of a desalination facility by avoiding impacts on the Salinas Valley Groundwater Basin and limiting the amount of additional environmental review since a 11,000 AFY facility has already been evaluated in the CWP DEIR.
Focus on Conservation and Reclamation Supplemented by Desalination
A sustainable water supply starts with using existing resources before developing a costly desalination project. The Hybrid Regional Plan focuses on the use of excess flows from the Carmel River, reclaimed water and water conservation.
Up to 10,000 AFY of wastewater is available for reclamation. Both the Hybrid Regional Plan and the Regional Plan propose using reclaimed water for urban landscaping. Both plans also propose using advanced treated wastewater (reclaimed water) from the MRWPCA to replenish the Seaside Aquifer. The difference is that the Hybrid Regional Plan proposes Seaside Aquifer replenishment with reclaimed water as a Phase I project, while the Regional Plan delays it until Phase II.
The proposed water conservation measures are identified in the May 7, 2009 Administrative Law Judge draft opinion. Measures to reduce unaccounted for water by replacing Seaside pipelines and electronic lead monitoring would total over 1,000 AFY as proposed in the Hybrid Regional Plan. These measures are not included in the Regional Plan.
The Hybrid Regional Plan would use water from the Sand City desalination plant until 2016 when it is to be returned to Sand City for its use.
A desalination plant at just less than 6,000 AFY would supplement the measures identified above.
Table 2 identifies water supply programs in each of the alternatives.
Phase II of the Hybrid Regional Plan would assess the effectiveness of the projects identified above and make adjustments accordingly. This phase would address drought reserve, water for growth and water for North Salinas Valley.
