This TMDL addresses nutrient impairments for a number of springs in the Suwannee River (downstream of the confluence with the Withlacoochee River) basin and the Lower Suwannee Estuary. These waterbodies were verified as impaired by nitrate-N using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters. A concentration target was used to establish the nutrient TMDL. The existing language for a Total Coliform TMDL in the Fenholloway River is being deleted, as “Total Coliform” is no longer a surface water quality criterion (EPA approved this revision to Florida’s surface water quality standards on May 4, 2007).
