The department announces the availability of the FINAL lists of impaired waters for the Group 4 Basins: Pensacola Bay, Nassau River-St. Marys River, Withlacoochee River, Kissimmee River, Fisheating Creek, and Southeast Coast-Biscayne Bay. These lists were adopted by an Secretarial Order signed on November 2, 2010. The Verified and Delist lists can be found at the links provided below. Requests for an administrative hearing to challenge a listing decision must be received no later than December 3, 2010.

These lists represent the second rotation through the Group 4 basins and another step in the process of restoring impaired waters for these basins. Now that these lists have been adopted by Secretarial Order, the Department staff will begin developing TMDLs for waters on the verified list. A TMDL represents the maximum amount of pollutant loading that can be discharged to a water body and have its designated uses be met. After TMDL adoption, the next step in this process will be the development, by watershed stakeholders and DEP, of a Basin Management Action Plan (BMAP). The BMAP will specify the activities, schedule, and funding sources that point and nonpoint source dischargers will undertake to restore the water body.

The next rotation through these basins is scheduled to begin in July 2015.
