These studies will be completed in late 2014. • October 16, 2013 Commission approved extending investigation phase of initial designation proceedings through December 2014 to allow: • - more consultation with affected parties • - ongoing studies in area to be completed Hawaii County Council Meeting - February 4, 2014 Department of Land and Natural Resources Commission on Water Resource Management Designation Process (HRS 174C-41 to 46, HAR 13-171-3 to 9) Initiation Chairperson or Written Petition • Studies & Water Use Reports 60 days • Federal Water Agencies Input OR Consult w/ County DOH Input Extend • Public Hearings (optional) (Council, IMayor, BWS) • Chair's Recommendation CWRIVI Decides Whether to Contin - Designation Process Process Ends YES Public Public Notice (3 weeks & hearing date ) 90 days • Ground water Designation — 8 Criteria V►dLer Designation — 3 Criteria Decision NO Process Ends YES Public Notice / Begin Water Use Permit Process 23 Department of Land and Natural Resources Commission on Water Resource Management If Keauhou ASA is Designated : • Public Notice.
