Carlsbad prioritization

At this point, the company didn’t have enough staffing to be working on two desal projects. Poseidon decided to place Huntington Beach on the backburner and prioritize Carlsbad because the Carlsbad project was further along, according to VP Maloni.


Carlsbad Plant is approved by the Carlsbad City Council, the Regional Water Control Board and the California Coastal Commission

OC District Letter

OCWD submits a letter to the Santa Ana Regional Water Quality Control Board (Regional Board) in support of the Project’s National Pollutant Discharge Elimination System (NPDES) permit and advised the Regional Board that OCWD would “be opposed to any alternative seawater intake system that could potentially impact the efficacy of Talbert Aquifer Seawater Intrusion Barrier on the groundwater basin, unless the impacts were adequately mitigated.”

Building begins

Water Purchase Agreement executed between Poseidon Water and the San Diego County Water Authority (SDCWA); $734 million in private bonds sold; construction begins on Carlsbad Desalination Project

May 2013
California Law/Politics

OCWD Board of Directors resolves that it is the goal of OCWD to consider and develop a variety of local water resources—including seawater desalination—to ensure sufficient water supplies are always available to the residents and businesses in the service territory.

July 2013
California Law/Politics

OCWD Board of Directors approved executing an amendment to the 2010 Confidentiality Agreement with Poseidon Resources, giving OCWD access to additional information to study the project's economic feasibility and consider a water purchase agreement for the entire proposed 50-million-gallon-per-day production capacity of the plant. At that time, OCWD’s Board also directed its staff to conduct a financial evaluation of the project.

October 2013
California Law/Politics

OCWD submits a letter to the California Coastal Commission stating, “The District believes the Project is beneficial to enhancing regional water supply reliability by diversifying Orange County’s portfolio with a new local drought-proof source … In addition to offsetting imported demand, water from the Project could provide flexibility in how the District manages the groundwater basin, specifically, the desalinated water could be used to augment supplies we inject into our Talbert Seawater Barrier to help prevent seawater intrusion into the groundwater basin.”

November 2013
California Law/Politics

The OCWD’S Board of Directors authorizes OCWD support for the California Coastal Commission to approve development of the Poseidon Resources Huntington Beach Ocean Desalination Project.

CCC Independent scientific technical advisory panel

The California Coastal Commission assembles an independent scientific technical advisory panel (ISTAP) to assess feasibility of alternative ocean intake technology. The expert panel was completing phase 2 and preparing to enter phase 3 when the State Water Board adopted its new Ocean Plan amendment on desalination regulations. That amendment requires all seawater desalination facilities use the “best available” site, design, technology, and mitigation measures feasible. It also establishes that the State and Regional Boards have primary authority to determine whether proposed facilities meet that standard. The amendment also establishes that subsurface intakes are the preferred method for facilities to obtain seawater.

HB Application attempt 1

Poseidon withdraws application  after California Coastal Commission tells them they need more information

Huntington Beach

OCWD staff released a comprehensive report titled “Poseidon Resources Huntington Beach Ocean Desalination Project Information and Update.” The report summarizes the water reliability advantages and financial impacts if OCWD were to purchase the Project’s 56,000 acre-feet/year of water and then resell the water to interested retail water agencies.

California Law/Politics

OCWD’s Board of Directors defers establishing the Ocean Desalination Citizens’ Advisory Committee.

February 2014
California Law/Politics

OCWD submits a letter to Governor Brown urging regulatory relief for seawater desalination projects that stated, “It is imperative that any drought relief legislation encourages and supports the creation and development of desalination for new water supply.”

June 2014
California Law/Politics

OCWD Board of Directors authorizes issuance of agreement to Clean Energy Capital for $49,720 to provide financial analysis on the proposed Poseidon Resources City of Huntington Beach Ocean Desalination Project.

October 2014
California Law/Politics

Clean Energy Capital (CEC) provides an informational presentation to the OCWD Board that summarizes its draft financial analysis report regarding the proposed Poseidon Resources Huntington Beach Ocean Desalination project. This was an informational item and the Board took no official action.

November 2014
Huntington Beach

Informational presentations given regarding the proposed Poseidon Resources Huntington Beach Ocean Desalination project at the Water Issues Committee meeting. The Board took no official action.

December 2014
California Law/Politics

OCWD Board of Directors votes to increase the Clean Energy Capital Contract by $27,000 to $76,720

December 2014
Huntington Beach

OCWD holds a special workshop, open to the public, to discuss the proposed Poseidon Resources Huntington Beach Ocean Desalination Facility. No board action is taken.

January 2015
Huntington Beach

The OCWD Board of Directors voted to begin negotiating a term sheet with Poseidon Resources to purchase 50 million gallons of water a day (56,000 acre-feet annually) created by the proposed Huntington Beach Ocean Desalination Plant. As part of this process, the Board decides to move forward with appointing an Ocean Desalination Citizens’ Advisory Committee (ODCAC) to ensure the public is provided ample opportunity to provide input. Each OCWD Board Member will appoint up to two committee members and an alternate member.

February 2015
California Law/Politics

OCWD Board of Directors votes to defer action regarding the adoption of recommended roles, responsibilities, and administrative procedures for the Ocean Desalination Citizens Advisory Committee to the March 18, 2015 Board of Directors meeting

March 2015
California Law/Politics

OCWD Board of Directors votes to appoint members of the Ocean Desalination Citizens Advisory Committee (ODCAC). The Board also voted to schedule ODCAC meetings on March 26, 2015; April 9, 2015; and April 23, 2015; at 5:30 p.m. ODCAC will provide input on the draft term sheet and the project in general. It will operate according to the established Roles, Responsibilities, and Administrative Procedures.

May 2015
Huntington Beach

OCWD’s Board of Directors approves the term sheet with Poseidon Water as presented. Staff is authorized to hire and execute contracts with consultants for a total amount not to exceed $230,000 to review project issues relating to distributing the Poseidon water, water quality, considering alternative supplies, and financial assistance. Staff is further authorized to seek bond funding for such a project. Directors Flory and Yoy requested that the Citizens Advisory Committee reconvenes during review of the term sheet. The Board agreed to defer this discussion to a future meeting.

September 2015
HB Application attempt 2

At the OCWD Board of Directors meeting, Poseidon Resources announced they had resubmitted its application to the California Coastal Commission for the proposed Huntington Beach Desalination Project for the last remaining Coastal Development Permit it needs to build the facility.

September 2015
HB Application attempt 2

This was contrary to the staff’s recommendation that Poseidon fund a third phase of the ISTAP review to determine the feasibility of alternative sites along the Orange County shoreline. This application was later withdrawn in the fall of 2016, just before it was scheduled to go to hearing and after a staff report was completed. The environmental community and local citizen groups oppose this project because it does not meet recommendations by the science community to minimize threats to marine life and address energy implications. Approving the Poseidon facility would set the worst possible standard for future ocean desalination proposals statewide. Poseidon’s Huntington Beach project proposal will create tremendous economic and environmental adverse impacts.

June 2016
Huntington Beach

OCWD’s Board of Directors approves amending the Confidentiality Agreement with Poseidon Resources to extend until December 31, 2019. The Board approves the Reimbursement Agreement with Poseidon Resources and authorizes the preparation of CEQA documents for the proposed project for a cost not to exceed $500,000.

California Law/Politics

Poseidon refuses to withdraw its CDP application, unless state agencies (the California Water Board, California Coastal Commission, and State Lands Commission) develop an expedited review sequence with Poseidon (that the SLC will complete its CEQA review; that the Regional Board staff will develop a tentative decision within 90 days of receiving all necessary information from Poseidon and of completion of the proposed project’s CEQA requirements; and that California Coastal Commission staff will schedule a hearing on Poseidon’s new CDP application within 90 days of the Regional Board’s published tentative determination of Poseidon’s project’s conformity with the Desalination Amendment)

California Ocean Plan

https://www.waterboards.ca.gov/water_issues/programs/ocean/docs/cop2015.pdf - Stricter rules for how ocean water could be taken into a desalination plant and how the brine byproduct of desalination was to be pumped back into the ocean.

Carlsbad was able to be built in exception to these regulations, Huntington Beach sent it back to the drawing board.
