The purpose of the proposed rules 62-42.100, 62-42.200, and 62-42.300, F.A.C., is to establish and adopt Minimum Flows and Levels (MFLs) for water bodies in Florida. Specifically, in Rule 62-42.100, the Department proposes for adoption a scope identifying the purposes of the rule chapter and recognizing that recovery and prevention strategies may contain non-regulatory provisions to be included in the applicable district water supply plans. Rule 62-42.200 proposes for adoption technical definitions necessary to understand the other rules in the chapter (specifically, proposed Rule 62-42.300, F.A.C.), including the definitions of a Flow Duration Curve and a Flow Duration Frequency. Rule 62-42.300 proposes for adoption MFLs for the Lower Santa Fe and Ichetucknee Rivers and Associated Priority Springs.
