Section 62-304.435 - Upper East Coast Basin TMDLs(1) Spruce Creek (Freshwater Segment). The bacteriological TMDL for the freshwater segment of Spruce Creek is 400 counts/100mL for fecal coliform, and is allocated as follows:(a) 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 1997 to 2005 period, will require a 53% reduction at sources contributing to exceedances of the criteria; and(b) 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 1997 to 2005 period, will require a 53% reduction at sources contributing to exceedances of the criteria.(2) Spruce Creek (Marine Segment). The TMDL for the marine segment of Spruce Creek is based on achieving the Class 3 marine minimum DO criterion of 4.0 mg/L, and is allocated as follows: (a) The WLA for discharges subject to the Department's NPDES MS4 Permitting Program is a 25% reduction of current anthropogenic BOD loading, and a 27% reduction of current anthropogenic TP loading based on measured concentrations from the 1992 to 2005 period; and(b) The LA for nonpoint sources is a 25% reduction of current anthropogenic BOD loading, and a 27% reduction of current anthropogenic TP loading based on measured concentrations from the 1992 to 2005 period.(3) Pellicer Creek. The bacteriological TMDL for Pellicer Creek is 43 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 2004, 2005, and 2009, will require a 94% reduction of sources contributing to exceedances of the criteria.(4) Tomoka River (Fresh Water Segment). The TMDL to address the nutrient impairment in the freshwater segment of Tomoka River is an annual average TN and TP concentration of 0.78 mg/L and 0.065 mg/L, respectively, 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 Permitting Program (MS4) is a 30% reduction of current anthropogenic TN loading, and a 30% reduction of current anthropogenic TP loading based on measured concentrations from the 1992 to 2011 period; and(c) The LA for nonpoint sources is a 30% reduction of current anthropogenic TN and TP loadings based on measured concentrations from the 1992 to 2011 period.(5) Halifax River (Northern Segment). The TMDL to address the nutrient impairment in the northern segment of Halifax River is an annual average TN and TP concentration of 1.13 mg/L and 0.185 mg/L, respectively, and is allocated as follows:(a) The WLA for the Ormond Beach Wastewater Treatment Facility (WWTF) is 109, 666 lbs TN/yr and 18, 278 lbs TP/yr. The WLA for the Holly Hill WWTF is 21, 933 lbs TN/yr and 7, 311 lbs TP/yr. The WLA for the Daytona Beach/Bethune Point WWTF is 182, 777 lbs TN/yr and 60, 926 lbs TP/yr;(b) The WLA for discharges subject to the Department's NPDES MS4 Permitting Program (MS4) is a 9% reduction of current anthropogenic TN loading based on measured concentrations from the 1995 to 2010 period; and(c) The LA for nonpoint sources is a 9% reduction of current anthropogenic TN loading, based on measured concentrations from the 1995 to 2010 period.(6) South Matanzas River (from the City of Palm Coast to the northern portions of Flagler Beach). The TMDL to address the nutrient impairment in the South Matanzas River from the City of Palm Coast to the northern portions of Flagler Beach is an annual TN and TP load of 807, 418 lbs TN/yr and 86, 685 lbs TP/yr, and is allocated as follows: (a) The WLA for the Palm Coast WWTF#1 is 111, 190 lbs TN/yr and 30, 466 lbs TP/yr. The WLA for the Palm Coast WWTF #2 facility is WLA is 6, 483 lbs TN/yr and 1, 625 lbs TP/yr. The WLA for Beverly Beach WWTF is 4, 606 lbs TN/yr and 503 lbs TP/yr. The WLA for the Dunes CDD-Reverse Osmosis Concentrate facility is 1, 531 lbs TN/yr and 323 lbs TP/yr;(b) The WLA for discharges subject to the Department's NPDES MS4 Permitting Program is a 29% reduction of current anthropogenic TN and TP loadings based on measured concentrations from the 1997 to 2009 period; and(c) The LA for nonpoint sources is a 29% reduction of current anthropogenic TN and TP loadings based on measured concentrations from the 1997 to 2009 period.Fla.
