The Proposed Poseidon Seawater Desalination Facility
A Practical Assessment of Need, Feasibility, Environmental Impacts, and Policy Implications PRESENTED BY: This needs points from Debbie

Poseidon’s Desalination Plant is Not Needed

Poseidon: What They Do “We secure premier desalination plant locations co- located with power plants….with the capability to intake or discharge seawater….” “Technology neutral approach enables tailored cost- optimized projects.” “Possess intellectual property for desalination co-location with power plants.” I could not get rid of the second text box so please remove it. Is there a way to put a footnote to their website page? Source:

CA Statewide Policy Advances-- Poseidon’s Desal Design Doesn’t
Policy Advancements Since Approval of Carlsbad Plant in 2007 2010 SWRCB orders phase out of open ocean intake at 19 coastal power plants including Carlsbad and AES. MPAs for Southern CA are approved by Fish & Game Commission. 2014 SWRCB intends to adopt the Ocean Plan Amendment that establishes statewide standards for desalination facilities. 2005 SWRCB policy discussion begins to phase out open ocean intakes begins. 2007 Poseidon Carlsbad CDP approved with open ocean intake. 2012 AES applies to decommission open ocean intake by 2020 or earlier. 2011 SWRCB convened Expert Panels in preparation for Statewide Desalination Policy. 2013 SWRCB Expert Panels on Desalination publish recommendations. SWRCB to release Draft Policy before 2014.

Co-Location vs. Best Available Technology
Poseidon Co-locates with power plants to reduce construction costs Open ocean intake maximizes marine life mortality with potential adverse impacts to MPAs Open discharge results in large brine plume Designed for profit Best Available Technology Located where needed and site conditions are optimal Subsurface intake minimizes marine life mortality and limits potential adverse impacts to MPAs Spray brine diffuser reduced brine plume up to 90% Designed to meet need

Subsurface is Feasible

I want to use THEIR slide and the worst one possible. The pic on the right was not very descriptive so I changed it.
7
Poseidon Must Prove that Subsurface is Infeasible
Poseidon cites several Water Globe reports and memos to claim that subsurface intakes are infeasible. Report was prepared by Nikolay Voutchkov, a former Senior Vice President for Technical Services for Poseidon Resources. Voutchkov is the inventor of the patent for co-location that was assigned to Poseidon Resources in 2005. The CCC cannot rely on the Voutchkov ‘report’ to determine infeasibility.
8
Poseidon Never Proved Subsurface is Infeasible
Others performed onsite feasibility studies first, then designed their project. Poseidon designed its project first and never performed site specific studies offshore. A report submitted 6 weeks ago by a former Poseidon employee only indicates wells cannot be built. Staff has never suggested wells.

Poseidon and SDCWA Accounted for Subsurface Intakes in their “Financial Planning” for Carlsbad
The Water Purchase Agreement acknowledges that a new intake system could be required in 2017 at Carlsbad given a ‘change in law’ as a result of the “closure and decommissioning” of the open ocean intake as required by the OTC policy. Poseidon and the SDCWA told the New York Times in 2013 that they had accounted for the “eventuality” of subsurface intakes in their “financial planning.” Carlsbad was successfully financed with $734M in Tax Exempt Private Activity Bonds and $189M in private equity based on the WPA as collateral.

Proposed Open Ocean Intake
Obsolete technology built in 1958 for a Power Plant Documented marine impacts 100 mile Source Water Population (SWP) Tons of chemical additives a day 4 million+ gallons of wastewater discharge per day
11
Brine Discharge Hypersaline brine contains residual chemicals, degrades water quality and displaces marine life Proposed vertical open discharge designed for hot water not brine Spray Brine diffuser would reduce Zone of Initial Dilution (ZID) by 90%

Poseidon’s Temporary Permits are not Entitlements
Temporary Co-Location Permits NPDES Permit State Lands Commission Lease California State Parks Easement Department of Public Health Pipelines Routes within Costa Mesa Permit for Standalone Operation 2020 Not Final EIR May Be Required
17
Temporary NPDES Permit
Under temporary stand-alone operations, the Discharger has little control over the intake structure. Under these conditions, the existing intake meets the best available design criteria. Pursuant to Water Code Section (b), the direct connection of the desalination plant to the HBGS's cooling water system pipelines represents the best available design feasible to minimize intake and mortality to marine life from the Facility's temporary stand-alone operations. Because different and/or better designs may be feasible in the future under long-term stand-alone operations, the Regional Water Board will reevaluate the Facility's compliance with Water Code section (b), best design available requirement, under those conditions.
18
Poseidon Intentionally Provided False Information in Carlsbad GHG Plan
2008 GHG Hearing: Poseidon assured the Commission that “water from the desalination plant will provide direct, one-for-one replacement of imported water”—Nov. 9, 2007 Poseidon letter 2010 Revocation Hearing: “Water eligible for MWD’s subsidy exclud[es] any Desalinated Seawater that…will not augment water supply.”—2005 MWD agreement Need to add bullet points in. And this cite from the 2005 is not the clearest language. Is there anything that is more direct and not convoluted? AC “We expect MWD to take its full SWP and Colorado River rights and entitlements for the foreseeable future”—Jan. 20, 2010 MWD/SDCWA letter
19
Poseidon Has Provided The Same False Information Again
HB GHG Plan: “Poseidon will be credited with emission reductions associated with the replacement of imported water from the SWP.” Staff Report: “Poseidon’s project will not ensure a decrease in imported water supplies to Southern California…this [automatic] ‘crediting’ approach to achieving carbon neutrality is not warranted.”

Which Project Design Offers More Jobs?
Poseidon Plant as Proposed Continued Use of Open Ocean Intake Pipe Constructed in 1958 CCC Staff Recommendation Additional Construction of: Water Infiltration gallery Subsurface Pump Station Connecting pipes Service road This goes as the next to last slide. The extra construction is what Poseidon told Bocho they would have to construct.
