Final Verified and Delist Lists of Impaired Waters for the Group 5 Basins
The department announces the availability of the FINAL lists of assessments for waterbodies and water segments within the Group 5 Basins: Everglades, Florida Keys, Indian River Lagoon, Perdido, Spring Coast, and Upper East Coast.
These FINAL lists were produced with water quality and biological data included in the IWR Database Run 54_2 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. In addition, new data has been received and incorporated into the assessments, station-WBID assignment updates, WBID classification updates, and/or data that have been excluded from assessments based on a evaluation by department staff. These final lists were adopted by a Secretarial Order signed by DEP Secretary Noah Valenstein, on June 27, 2018.
Waterbodies and water segments identified on the FINAL Verified List have been determined to not meet water quality standards and 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 proposed for removal from the State’s Verified List and federal 303(d) list for several reasons: 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 will be prioritized and scheduled for TMDL development. 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 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 waterbody.
