It is the intent of the Legislature that the public have maximum input into the formulation of state water policy. The director shall conduct one or more public hearings prior to the completion of any recommendations to the Legislature on methods of addressing water policy issues. All materials produced as part of the state water planning and review process shall be available to interested persons and groups upon request. The department or other agency providing such material may make a charge therefor which does not exceed the actual cost of providing the same.
