Requires Applicants To:

4. The Governing Board finds that:  “… consumptive withdrawals of surface water from the main stem of the Chipola River and the Chipola Cutoff are not in the public interest…”  … the “magnitude, duration and frequency of observed flows are reserved for the protection of fish and wildlife of the Chipola River, Apalachicola River, the associated floodplains and Apalachicola Bay. (Ch. 40A-2.223 F.A.C.)” Note: Diversions of surface water for cooling purposes, fish and wildlife propagation or refuge, migratory bird hunting refuges and similar diversions are exempt... provided that diverted water is returned to the Apalachicola River Basin.
