Financing and legal hurdles still ahead for Carlsbad desalination

From the International Desalination and Water Reuse Quarterly:

The labyrinthine complexities of the desalination permitting process in California were further illustrated this week with the latest twists in the Carlsbad seawater desalination plant saga.

At a public hearing on 8 April 2009, the San Diego Regional Water Quality Control Board concluded that the new coastal wetlands proposed by Poseidon as a part of the project will be adequate to mitigate both impingement and entrainment impacts of the desalination plant, when and if it operates as a stand-alone facility in the future.

This, as Nikolay Voutchkov from project promoters Poseidon Resources points out, is unlikely, as the plant will use cooling water from the collocated Encina power station. Since the power station is anticipated to be operational at least for the near future, the actual impingement impact of the plant is expected to be significantly smaller than the assessment presented at the board, which assumes that all of the intake impingement is associated with the desalination plant operations.

The approval was given despite a difference of opinion between Poseidon and the board’s staff about precisely how many marine organisms would be affected.
