(1) Juniper Creek TMDL. The DO TMDL for Juniper Creek is based on achieving the Class 3 fresh water minimum DO criterion of 5.0 mg/L, 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 TN criteria which, based on the measured concentrations from the 1979 to 2006 period, will require a 18.18% reduction at sources contributing to exceedances of the criteria; and
    (b) The Load Allocation (LA) for nonpoint sources is to address anthropogenic sources in the basin such that in-stream concentrations meet the total nitrogen (TN) criteria which, based on the measured concentrations from the 1979 to 2006 period, will require a 18.18% reduction at sources contributing to exceedances of the criteria.
    (2) Juniper Creek. The bacteriological TMDL for Juniper 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 1992 to 2007 period, will require a 48.1% 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 1992 to 2007 period, will require a 48.1% reduction at sources contributing to exceedances of the criteria.
    (3) Black Creek. The bacteriological TMDL Total Maximum Daily Load for the freshwater segment of Black 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, there currently are no NPDES point sources located in Black Creek;
    (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 1992 to 2007 period, will require a 39.6% reduction at sources contributing to exceedances of the criteria.
    (4) Swamp Creek. The bacteriological TMDL for Swamp 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 1992 to 2007 period, will require a 69.2% 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 1992 to 2007 period, will require a 69.2% reduction at sources contributing to exceedances of the criteria.
    (5) Lake Tallavana. The nutrient TMDL for Lake Tallavana is a seven-year average of annual loads of 11,757 kilograms per year (kg/year) TN and 785 kg/year TP which are intended to achieve the applicable AGM chlorophyll a criterion for high color lakes, 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 a 25% reduction of TN and an 83% reduction of TP based on average loads from the 2002-2012 period.
    (6) Lake Talquin. The nutrient TMDL for Lake Talquin is a seven-year average of annual loads of 1,134,850 kg/yr TN, and 112,326 kg/yr TP, which are intended to achieve the applicable AGM chlorophyll a criterion for high color lakes, and is allocated as follows:
    (a) The WLA for the Quincy WWTF (Permit Number FL0029033) is 4,745 kg/yr of TN and 1,460 kg/yr of TP; and the WLA for the Arvah B. Hopkins Power Plant (Permit Number FL0025518) is 986 kg/yr of TN and 2,409 kg/yr of TP;
    (b) The WLA for discharges subject to the Department’s NPDES MS4 Permitting Program is a 19% reduction in TN (calculated from 1,396,458 kg/yr) and a 21% reduction in TP (calculated from 142,659 kg/yr), based on the maximum 7-year average load from the 2008 – 2017 period; and
    (c) The LA for nonpoint sources is a 19% reduction in TN (calculated from 1,396,458 kg/yr) and a 21% reduction in TP (calculated from 142,659 kgs/yr), based on the maximum 7-year average load from the 2008 – 2017 period.
