Monterey Peninsula Water Supply Project

(Application A.12-04-019, filed April 23, 2012)

Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of the proposed California-American Water Company (CalAm) Monterey Peninsula Water Supply Project (MPWSP or proposed project). An application for this project was submitted to the CPUC on April 23, 2012 (Application A.12-04-019 [pdf 9.46mb]). This website will be used to post all relevant public documents during the environmental review process and to announce any upcoming public meetings.

PLEASE NOTE: Other websites, including the previous website: http://www.cwp-eir.com, are no longer associated with the project, and active content posted on those websites is not relevant to the Monterey Peninsula Water Supply Project.

Availability of Draft Environmental Impact Report for the Monterey Peninsula Water Supply Project

The CPUC has prepared a Draft Environmental Impact Report (Draft EIR) consistent with the California Environmental Quality Act (CEQA) for consideration of the California American Water Company (CalAm) application (A.12-04-019) for a Certificate of Public Convenience and Necessity (CPCN) to develop a replacement water supply for CalAm's Monterey District service area. The release of the Draft EIR starts a review and comment period. To view the Notice of Availability, click here. The MPWSP Draft EIR is available below, and in public libraries. CDs are available upon request and were available at the public meetings.

!!!NEW!!! The Energy Division has extended the comment period again. Written comments are now due by September 30, 2015. See the notice here.

Introduction and Project Purpose

The MPWSP would include a 9.6 million gallon per day (mgd) desalination plant and facility improvements to the existing Seaside Groundwater Basin ASR system to secure water supplies for the approximately 40,000 customers in CalAm's Monterey District service area. Click here for a project location map. As an alternative to the 9.6-mgd desalination plant, CalAm's application also includes a 6.4-mgd desalination plant coupled with a water purchase agreement for 3,500 afy of product water from the Monterey Regional Water Pollution Control Agency's proposed Pure Water Monterey Groundwater Replenishment Project. The MRWPCA has prepared a separate EIR for the Pure Water Monterey Groundwater Replenishment Project. That Draft EIR is also available for public review at purewatermonterey.org

The primary purpose of the MPWSP is to replace existing water supplies that have been constrained by legal decisions affecting the Carmel River and Seaside Groundwater Basin water resources. SWRCB Order 95-10 requires CalAm to reduce surface water diversions from the Carmel River in excess of its legal entitlement of 3,376 acre-feet per year (afy), and SWRCB Order 2009-0060 ("Cease and Desist Order") requires CalAm to develop replacement supplies for the Monterey District service area by December 2016. In 2006, the Monterey County Superior Court adjudicated the Seaside Groundwater Basin, effectively reducing CalAm's yield from the Seaside Groundwater Basin from approximately 4,000 afy to 1,474 afy.




Background Information

Background

In 2004, CalAm filed Application A.04-09-019 seeking a Certificate of Public Convenience and Necessity from the CPUC for the Coastal Water Project. The Coastal Water Project (CWP) was intended to replace existing Carmel River water supplies for the CalAm Monterey District service area that are constrained by the SWRCB decisions. In general, the previously proposed CWP involved the production of desalinated water supplies, increased yield from the Seaside Groundwater Basin ASR system, and additional storage and conveyance systems to move the replacement supplies to the existing CalAm distribution system. On January 30, 2009, the CPUC published a Draft Environmental Impact Report (EIR) analyzing the environmental impacts of the CWP proposed project (also referred to as the Moss Landing Project), as well as the environmental impacts of two project alternatives-the North Marina Project and the Regional Project. The CPUC published the Coastal Water Project Final EIR (SCH No. 2006101004) in October 2009 and certified the EIR in December 2009 (Decision D.09-12-017). A year later, in Decision D.10-12-016, the CPUC approved implementation of the Regional Project alternative.

Subsequent to approval of the Regional Project, CalAm withdrew its support for the Regional Project in January 2012 (The CPUC subsequently closed the CWP proceeding in Decision D.12-07-008 [July 12, 2012]). As a result, in April 2012, CalAm submitted Application A.12-04-019 to the CPUC for the Monterey Peninsula Water Supply Project (MPWSP). The MPWSP is intended to secure replacement water supplies for the Monterey District associated with legal decisions affecting existing supplies from both the Carmel River and the Seaside Groundwater Basin (see discussion under the heading, Project Purpose, for more information). The MPWSP includes many of the same elements previously analyzed in the CWP EIR; however, key components, including the seawater intake system and desalination plant, have been relocated and/or modified under the current proposal.

Proposed Project

The proposed MPWSP would be comprised of the following facilities:

  • A seawater intake system consisting of ten 750-foot-long subsurface slant wells extending offshore into the Monterey Bay, and appurtenant facilities. The preferred site for the subsurface slant wells is a 376-acre coastal property located north of the city of Marina and immediately west of the CEMEX active mining area. New pipelines would convey the seawater (or "source water") from the slant wells to the MPWSP desalination plant.
  • A 9.6 million gallon per day desalination plant and appurtenant facilities on a 46-acre vacant parcel near Charles Benson Road, northwest of the Monterey Regional Water Pollution Control Agency's (MRWPCA) Regional Wastewater Treatment Plant and the Monterey Regional Environmental Park. Facilities proposed at the MPWSP desalination plant include pretreatment, reverse osmosis, and post-treatment systems; chemical feed and storage facilities; a brine storage basin; and an administrative building. Brine produced during the desalination process would be conveyed to an existing MRWPCA ocean outfall and discharged to the Monterey Bay. Approximately 9,700 afy of potable water supplies would be produced by the proposed desalination facilities.
  • Up to 28 miles of desalinated water conveyance pipeline and mains, and associated facilities including pump stations, clearwells, and a terminal reservoir.
  • Improvements to the existing Seaside Groundwater Basin ASR system, including two additional injection/extraction wells, a pump station, and associated pipelines.

As an alternative to the 9.6-mgd desalination plant, CalAm's application also includes a 6.4-mgd desalination plant coupled with a water purchase agreement for 3,500 afy of product water from the MRWPCA's proposed Pure Water Monterey Groundwater Replenishment Project.

CEQA Environmental Review

Pursuant to CEQA Guidelines Section 15162, the CPUC has determined that a Subsequent EIR is the appropriate level of CEQA review for the MPWSP. The MPWSP DEIR provides a comprehensive description and evaluation of all proposed components (including the new proposed elements and previously analyzed components) as the "whole of the action." The MPWSP DEIR evaluates alternatives not previously considered in the previous CWP EIR.

Coastal Erosion Technical Memo

CalAm proposes infrastructure associated with the Monterey Peninsula Water Supply Project that is located near or along the Monterey Bay coastline. The primary focus of this memo is to describe coastal processes that could be relevant to assessing the environmental effects of the Project and the viability of Project alternatives, and to identify potential damages to Project infrastructure from coastal erosion.

The Technical Memo is available as an appendix to the Draft EIR.
