The Department is initiating rulemaking to establish Total Maximum Daily Loads (TMDLs) for waters in the St. Marks (Ames Sink, Lake Munson, and Munson Slough), Ochlockonee River (Black Creek, Juniper Creek, and Swamp Creek), Suwannee River (Middle and Lower Suwannee River and associated springs), Santa Fe River (Alligator Lake, New River, and Santa Fe River), and the Everglades West Coast (Cocohatchee River, Gordon River, Hendry Creek, Imperial River, and Lake Trafford) Basins. Pursuant to Section 403.067(6), F.S., TMDLs must be adopted by the Secretary of the Department by rule. Chapter 62-304, F.A.C., was established as the rule chapter within which rules adopting TMDLs shall reside. Establishment of TMDLs is proceeding for waters within the above basins for which the verified list of impaired waters previously were adopted by Secretarial Order. TMDL calculations and allocations for each waterbody or waterbody segment will be adopted by rule, by the Secretary of the Department, pursuant to Sections 120.536(1), 120.54 and 403.805, F.S. These rules have been given individual OGC case numbers: 08-1892 for Rules 62-304.300, 08-1893 for 62-304.305, 08-1894 for 62-304.405, 08-1895 for 62-304.410, and 08-1896 for 62-304.810, F.A.C.
