The Department is initiating rulemaking to establish Total Maximum Daily Loads (TMDLs) for waters in the Caloosahatchee and St Lucie Basins. Pursuant to Section 403.067(6), Fla. Stat., 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. The verified lists for the Group 2 St Lucie and Group 3 Caloosahatchee basins were adopted by Secretarial Order on May 27th, 2004, and June 17th, 2005, respectively. In addition, in 2007, the Florida Legislature separately determined that a TMDL for nutrients should be done for the estuarine portion of the Caloosahatchee River. 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 the following OGC case numbers: 08-2290 for 62-304.705 and 08-2291 for 62-304.800.
