Fla. Admin. Code Ann. R. 62-304.310 - Apalachicola River Basin TMDLs

(1) Huckleberry Creek. The bacteriological TMDL for Huckleberry Creek is a median of 6.85 x 10⁹ colonies/day for fecal coliform, and is allocated as follows:

(a) The WLA for discharges 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.; and

(b) The LA for nonpoint sources is a median of 6.85 x 10⁹ colonies/day for fecal coliform, which constitutes a 68.33% reduction of current fecal coliform loading.

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

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

(b) The WLA for discharges subject to the NPDES MS4 Permitting Program, to address anthropogenic sources in the basin such that in-stream concentrations meet the fecal coliform criteria, 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 January 2007 to December 2007 period, will require a 38% reduction of sources contributing to exceedances of the criteria.

(3) Little Gully Creek. The TMDLs to address the low DO and nutrient impairments are an 11.3% reduction in both TN and TP and are allocated as follows:

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

(b) The WLA for discharges subject to the Department's NPDES MS4 Permitting Program, to address anthropogenic sources in the basin such that in-stream concentrations meet the DO criteria and nutrient targets, is not applicable; and

(c) The LA for nonpoint sources is an 11.3% reduction in current anthropogenic loadings of both TN and TP.

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

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

(b) The WLA for discharges subject to the Department's NPDES MS4 Permitting Program, to address anthropogenic sources in the basin such that in-stream concentrations meet the fecal coliform criteria, 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 January 2007 to December 2007 period, will require a 40% reduction of sources contributing to exceedances of the criteria.
