FACT SHEET TEMPLATE FOR WATER SUPPLY ALTERNATIVES

MPWMD Special Workshop, August 25, 2011

Alternative Type: Local Desalination

Project Name: Monterey Desalination Facility

Project Sponsors: MPWMD

Location: Next to Del Monte Beach in Monterey on U.S. Navy property across from

Naval Support Activity Monterey

Project Description: A two million gallon per day (MGD) seawater reverse osmosis (SWRO) desalting facility would be located next to the ocean at Del Monte Beach. This size facility would provide a little more than 2,000 acre-feet per year toward the near-term estimated water supply need for six cities on and near the Monterey Peninsula and portions of unincorporated Monterey County in Carmel Valley and along the Highway 68 corridor between Del Rey Oaks and the Laguna Seca raceway.

ATTRIBUTE	ESTIMATES	NOTES and COMMENTS
YIELD (AFY)	2,000 (average)	Intake water quality could affect the yield
COST	To be developed	Need to complete initial feasibility studies (preliminary site layout, investigate offshore environment, establish power requirements) before making an initial cost estimate.
TIMELINE	4-6 years	New rules concerning desalination along the California coast are under consideration and could affect timeline; Water delivery may not be feasible until 2016 or 2017.
PERMITS AND APPROVALS *Federal, State, Regional Agencies, Local Jurisdictions	NEPA, ESA, 404, 401 CEQA Coastal Development Permit	Partial list of permitting agencies: US NAVY, USFWS, NMFS, U.S. ARMY CORPS, EPA, Sanctuary, RWQCB, CCC, CDPH, City of Monterey, MBUAPCD
PROS AND CONS
*Benefits	*Reliable, known technology for Sea Water Reverse Osmosis (SWRO) *Many SWRO facilities have been built around the world (knowledge base to draw on)	*Landowner may be willing to enter into long-term lease; *Local officials of the US Navy would like to assist the community with its water supply problems; *Excess power capacity at Navy facility may be available; *Minimal pipeline costs to tie into Cal-Am system; *Water supply facility within MPWMD boundary; *Visual impairments at the site could be modified.
*Drawbacks	*EIR/EIS estimated at $500,000 to $1 million; *EIR/EIS development and review could take 2-3 years; *Permit process could be lengthy; *Complicated construction environment in ocean	*Disturbance/impacts to ocean environment if an open ocean intake/discharge is needed; *Site may be subject to coastal erosion/significant changes in offshore sand movement/ rising ocean levels; *Site is near sensitive dune environment; *Potentially variable intake water quality; *Neighborhood concerns (traffic, aesthetics); *Will require significant amount of power to operate; *Construction work must avoid other utilities in the area (storm drains, regional wastewater pipeline, power lines)
