Cal. Wat. Code § 10732.2
If a groundwater sustainability agency finds that a state entity is not working cooperatively regarding implementation of a groundwater sustainability plan, the groundwater sustainability agency may file notice with the board regarding its finding. The board shall notice proceedings to investigate the finding of the groundwater sustainability agency. If the board determines that the failure of the state entity to work cooperatively regarding implementation of a groundwater sustainability plan compromises the ability of the groundwater sustainability agency to implement the plan in a manner that will likely achieve the sustainability goal, the board may direct the state entity to cooperate in the implementation of the groundwater sustainability plan unless the state entity indicates its authority for not complying with a groundwater sustainability plan in the same manner as subdivision (f) of Section 10735.8.
