Triennial Review of Water Quality Standards

States are required under the Federal Clean Water Act (40 CFR 131.20) to conduct a comprehensive review of all water quality standards at least once every three years (Triennial Review). All surface water quality standards in Chapter 62-302, Chapter 62-303, Chapter 62-304, and Chapter 62-4, Florida Administrative Code (F.A.C.), are open under the current review and may be revised as part of the Triennial Review. However, the Department is not currently proposing revisions to Chapter 62-304, F.A.C., as part of the Triennial Review.

The Florida Department of Environmental Protection held a virtual public workshop on Wednesday, May 5, 2021 to solicit public input on the Department’s proposed revisions to Florida’s water quality standards under the Triennial Review. Please refer to the links below for the workshop materials.
