(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 Fl. Admin. Code Chapter 62-302; 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.
