A lawsuit seeking a new environmental report for the controversial Poseidon desalination plant proposed for Huntington Beach was rejected by a Sacramento Superior Court judge on Tuesday. Three environmental groups had filed the suit, arguing that the plant’s 2010 Environmental Impact Report needed to be entirely done over because of subsequent changes to the proposal. In its 2017 approval of the project, the State Lands Commission determined that Poseidon needed only to complete a supplemental report addressing the changes to the project, which proponents champion as a drought-proof source of local drinking water.
