Biennial Assessment 2020-2022 Final Verified and Delist Lists

FINAL Biennial Assessment 2020-2022 Verified and Delist Lists

(July 15, 2022)

The Watershed Assessment Section announces the 2020-2022 Biennial Assessment Final assessment lists of waterbodies and water segments proposed for addition to the Verified List and Delist List. The Final assessment lists were developed pursuant to Chapter 62-303, Florida Administrative Code (F.A.C.), include all 29 basins in the state and were adopted by Secretarial Order signed by DEP Secretary Hamilton on July 11, 2022. The Final Verified Lists include those waters that have been determined to not meet water quality standards and are additions to the State's Verified List of Impaired Waters and the Clean Water Act (CWA) section 303(d) list. The Final Delist Lists include those waters that are proposed for removal from the State's Verified List and CWA section 303(d) list for several reasons such as the waterbody is 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. Following the adoption by the Secretary of the department, waterbodies identified on the Final Verified List will be scheduled for TMDL production. A TMDL represents the maximum amount of pollutant loading that can be discharged to a waterbody and have its designated uses be met. 

These assessment lists were produced with water quality and biological data included in the IWR Run 60 Database that has been received by the department as of July 7, 2020. They also include station-WBID assignment updates, WBID classification updates and/or data that have been excluded from assessments based on a preliminary evaluation by department staff.
