Rule 62-304.335. Perdido Bay Basin TMDLs

Amended May 9, 2021 (current)

(1) Elevenmile Creek (US 90). The bacteriological TMDL is 400 counts/100 ml fecal coliform and is allocated as follows:

(a) The WLA for wastewater point sources subject to the Department’s NPDES Permitting Program is to meet the Class III water quality criteria for fecal coliform in Chapter 62-302, F.A.C.;

(b) The WLA for discharges subject to the Department’s NPDES MS4 Permitting Program is to address anthropogenic sources in the basin such that in-stream concentrations meet the fecal coliform criteria which, based on the measured concentrations from the 1972 to 2006 period, will require a 63% reduction at sources contributing to exceedances of the criteria; and

(c) The LA for nonpoint sources is to address anthropogenic sources in the basin such that in-stream concentrations meet the fecal coliform criteria which, based on the measured concentrations from the 1972 to 2006 period, will require a 63% reduction at sources contributing to exceedances of the criteria.

(2) Elevenmile Creek (State Road 297A). The bacteriological TMDL is 400 counts/100 ml for fecal coliform and is allocated as follows:

(a) The WLA for wastewater point sources subject to the Department’s NPDES Permitting Program is to meet the Class III water quality criteria for fecal coliform in Chapter 62-302, F.A.C.;

(b) The WLA for discharges subject to the Department’s NPDES MS4 Permitting Program is to address anthropogenic sources in the basin such that in-stream concentrations meet the fecal coliform criteria which, based on the measured concentrations from the 1972 to 2006 period, will require a 66% reduction at sources contributing to exceedances of the criteria; and

(c) The LA for nonpoint sources is to address anthropogenic sources in the basin such that in-stream concentrations meet the fecal coliform criteria which, based on the measured concentrations from the 1972 to 2006 period, will require a 66% reduction at sources contributing to exceedances of the criteria.

(3) Tenmile Creek. The bacteriological TMDL for Fecal Coliforms for Tenmile Creek is 400 counts/100 ml for fecal coliform and is allocated as follows:

(a) The WLA for wastewater point sources is not applicable;

(b) The WLA for discharges subject to the Department’s NPDES MS4 Permitting Program is to address anthropogenic sources in the basin such that in-stream concentrations meet the fecal coliform criteria which, based on the measured concentrations from the 1972 to 2006 period, will require a 43% reduction at sources contributing to exceedances of the criteria; and

(c) The LA for nonpoint sources is to address anthropogenic sources in the basin such that in-stream concentrations meet the fecal coliform criteria which, based on the measured concentrations from the 1972 to 2006 period, will require a 43% reduction at sources contributing to exceedances of the criteria.

(4) Brushy Creek. The bacteriological TMDL for Brushy Creek is 400 counts/100mL for fecal coliform, and is allocated as follows:

(a) The WLA for wastewater point sources is not applicable;

(b) The WLA for discharges subject to the Department’s NPDES MS4 Permitting Program is not applicable; and

(c) The LA for nonpoint sources is to address anthropogenic sources in the basin such that in-stream concentrations meet the fecal coliform criteria which, based on the measured concentrations from the 2004 to 2011 period, will require a 64% reduction of sources contributing to exceedances of the criteria.
