1General Duration Provision. When requested by an applicant, a consumptive use permit shall have a duration of 20 years provided the applicant provides sufficient data to demonstrate reasonable assurance that the proposed use meets the conditions for issuance for the requested 20 year permit duration; or otherwise, permits may be issued for a shorter duration that reflects the period for which such reasonable assurances can be provided. This determination will be made pursuant to requirements in Rule 7840E-2.301, 79F.A.C., and the “Applicant’s Handbook for Water Use Permit Applications within the South Florida Water Management District,” incorporated by reference in Rule 10240E-2.091, 103F.A.C.
