Opinion

Opinion

CORNELL, J.

Friends of the Santa Clara River and the Sierra Club appeal from the denial of their petition for writ of mandate alleging an urban water management plan for parts of the Santa Clarita Valley was adopted in violation of the Urban Water Management Planning Act (UWMP Act), Water Code section 10610 et seq. 1 Among the many grounds for reversal asserted is *4 the failure of the urban water management plan to assess the reliability of the water supply obtained from two layers of an aquifer contaminated with perchlorate.

Certain aspects of the urban water management plan concerning the effects of perchlorate contamination on the groundwater supply can be summarized as follows. If there is a dry stretch, the districts plan to take more water from the Saugus Formation. If the perchlorate contamination impairs the supply of water taken from the Saugus Formation in dry years, the districts plan to restore full production capacity by treating the contaminated water. While the treatment facilities are being built, the districts have no plan to cover the reduction in water available from the Saugus Formation.

Thus, the plan’s description of the perchlorate contamination and the method for addressing that contamination is flawed because it fails to (1) address the time needed to implement the available method for treating the contaminated water and (2) describe the reliability of the groundwater supply during that implementation period. As this gap in the reliability analysis is sufficient for reversal, we do not address the other challenges to the adoption of the plan. 2

FACTUAL AND PROCEDURAL SUMMARY

I. Parties

Friends of the Santa Clara River is a nonprofit corporation organized under the laws of the State of California in 1993. Some of its members reside within the subject service area and are ratepayers. The Sierra Club is a nonprofit corporation formed under the laws of the State of California in 1892. These parties are referred to collectively as plaintiffs.

Castaic Lake Water Agency (CLWA) is a public agency created and governed by the uncodified Castaic Lake Water Agency Law. (Stats. 1962, 1st Ex. Sess., ch. 28, § 1, p. 208, reprinted at 72A West’s Ann. Wat.—Appen. (1999 ed.) § 103-1 et seq., p. 487.) CLWA was formed to provide a supplemental supply of imported water to the water purveyors of the Santa Clarita Valley. Its area of wholesale water service covers approximately 195 square miles. CLWA contracts with California’s Department of Water Resources for water from the State Water Project (SWP) and other sources, treats those supplies at its treatment plants, and delivers the treated water to water retailers within its area.

*5 Newhall County Water District (Newhall) is a district formed by election under California’s County Water District Law (§ 30000 et seq.). Newhall is a retail water purveyor serving an area of approximately 34 square miles and supplies groundwater pumped from wells supplemented by imported water purchased from CLWA. At the end of 1999, Newhall served approximately 6,758 connections, i.e., accounts. 3

Santa Clarita Water Company (SCWC) is a California corporation and retailer of water. SCWC’s service area includes portions of the City of Santa Clarita and unincorporated areas of Los Angeles County in the communities of Saugus, Canyon Country and Newhall. SCWC supplies water from groundwater wells and imported water purchased from CLWA. 4 At the end of 1999, SCWC served approximately 21,100 connections.

Valencia Water Company (VWC) is a California corporation and retailer of water. VWC’s service area is approximately 25 square miles and includes portions of the City of Santa Clarita, the community of Valencia, and the unincorporated areas of Castaic and Stevenson Ranch. VWC supplies water from groundwater wells and imported water purchased from CLWA. At the end of 1999, VWC served approximately 20,865 connections.

CLWA, Newhall, SCWC and VWC are referred to collectively as defendants.

Defendants jointly caused the preparation of the 2000 Urban Water Management Plan (UWMP) under the UWMP Act to cover the service area of CLWA.

II. Sources of Water for the Santa Clarita Valley

Historically, the Santa Clarita Valley obtained its water supply from an underground water basin, or aquifer, that is about 84 square miles and is divided into an upper and lower level. The shallow level, called the Alluvial Aquifer, underlies the Santa Clara River and its tributaries. Water from this layer is obtained from wells up to 200 feet deep. Beneath the Alluvial Aquifer is a deeper layer of groundwater called the Saugus Formation. Water from the Saugus Formation is pumped from wells extending to approximately 2,000 feet in depth.

*6 Based on historical production, the UWMP estimates (1) the Alluvial Aquifer will supply 30,000 to 40,000 acre-feet per year in normal weather years and 30,000 to 35,000 acre-feet per year in dry years, and (2) the Saugus Formation will supply 7,500 to 15,000 acre-feet per year in normal weather years and 11,000 to 15,000 acre-feet per year in dry years. At the time the UWMP was adopted, groundwater from the aquifer accounted for approximately 54 percent of the water supplied in the CLWA service area.

Since 1980, imported water from the SWP has supplemented local supplies to meet community water requirements. CLWA owns three entitlements to water from the SWP that total 95,200 acre-feet per year. 5 In 1966, CLWA entered into a contract with the SWP for 41,500 acre-feet of water per year. In the 1980’s, CLWA purchased an entitlement to 12,700 acre-feet per year of SWP water from a Kern County water district. In 1999, CLWA acquired an entitlement to 41,000 acre-feet per year of SWP water from the Kern County Water Agency and its member district, Wheeler Ridge-Maricopa Water Storage District. 6

III. Proposal and Adoption of the UWMP

On Wednesday, November 22, 2000, defendants released a draft of the UWMP to the public for review and comment. CLWA indicated that public comments would be accepted only if received by it by 6:00 p.m., December 7, 2000.

The general manager of the United Water Conservation District sent a comment letter that expressed concerns about (1) the way the UWMP’s draft presented existing and future water supplies, (2) reliance on groundwater banking projects that were unavailable to CLWA or years away from operation, and (3) the uncertainty of how the Saugus Formation will react to the higher levels of pumping proposed. In particular, the letter states: “In the legislation concerning Urban Water Management Plans, agencies are asked to consider existing and future sources of water.
