FINAL Verified and Delist Lists of Impaired Waters for the Group 2 Basins

FINAL Verified and Delist Lists of Impaired Waters for the Group 2 Basins
 

The Department announces the availability of the FINAL lists of impaired waters for the Group 2 Basins: Apalachicola - Chipola, Charlotte Harbor, Lower St. Johns, Middle St. Johns, St. Lucie - Loxahatchee, and Tampa Bay Tributaries.

These FINAL lists were produced with water quality and biological data included in the IWR Database Run 58 and reflect several major milestones to the assessment of Florida’s waterbodies.  In particular, the FINAL lists include the revised dissolved oxygen criterion assessed as percent saturation (replacing the assessment of dissolved oxygen as mg/L), and the implementation of numeric nutrient criteria for streams, lakes, springs, and estuaries.  These final lists were adopted by Secretarial Order signed by DEP Secretary Valenstein on April 30, 2020. In addition to the final assessment lists, the department posted the Master Lists (which contains all assessments for all waterbodies in each basin) available here

Waterbodies and water segments identified on the FINAL Verified List have been determined to not meet water quality standards. These waters are being added to the State’s Verified List of Impaired Waters and will be submitted to EPA as updates to the federal 303(d) list. Waterbodies and water segments identified on the FINAL Delist Lists include those waters that are being removed from the State’s Verified List and federal 303(d) list for several reasons such as: the waterbody in no longer impaired, a TMDL has been completed, the parameter verified impaired in the previous assessment was due to a flaw in the original analysis, or corrections made to the waterbody type or class.  

Waterbodies identified on the FINAL Verified List are prioritized for TMDL development in accordance with Rule 62-303.500, Fla. Admin. Code. The department's long-term plan for prioritizing and developing site-specific TMDLs is available here. A TMDL represents the maximum amount of pollutant loading that can be discharged to a waterbody and have its designated uses be met. The final step in this process will be the development, by watershed stakeholders and department of a restoration plan that specifies the activities, schedule, and funding sources that point and nonpoint source dischargers will undertake to restore the waterbody. 

For best results, print on legal size paper (8.5 x 14).
