62-304.305. Ochlockonee Basin TMDLs  


Effective on Thursday, May 17, 2018
  • 1(1) Telogia Creek Planning Unit. Juniper Creek TMDLs.

    9(a) Juniper Creek TMDL for Dissolved Oxygen. The Total Maximum Daily Load for Juniper Creek is based on achieving the Class 3 fresh water minimum dissolved oxygen criterion of 5.0 mg/L, and is allocated as follows:

    451. The Wasteload Allocation (WLA) for discharges subject to the Department’s National Pollutant Discharge Elimination System (NPDES) Municipal Stormwater Permitting Program 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 percent reduction at sources contributing to exceedances of the criteria,

    1102. 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 percent reduction at sources contributing to exceedances of the criteria; and,

    1633. The Margin of Safety is implicit,

    1704. While the LA and WLA for dissolved oxygen has been expressed as the percent reduction needed to attain the applicable Class III criteria, it is not the intent of the TMDL to abate natural background conditions.

    207(b) Juniper Creek TMDL for Fecal Coliform. The Total Maximum Daily Load for Juniper Creek is 400 counts/100mL for fecal coliform, and is allocated as follows:

    2331. The Wasteload Allocation for discharges subject to the Department’s NPDES Municipal Stormwater 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 percent reduction at sources contributing to exceedances of the criteria,

    2912. The Load Allocation 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 percent reduction at sources contributing to exceedances of the criteria; and,

    3423. The Margin of Safety is implicit,

    3494. While the LA and WLA for fecal coliform have been expressed as the percent reductions needed to attain the applicable Class III criteria, it is the combined reductions from both anthropogenic point and nonpoint sources that will result in the required reduction of in-stream fecal concentration. However, it is not the intent of the TMDL to abate natural background conditions.

    410(2) South Ochlockonee River Planning Unit. Black Creek TMDLs. The Total Maximum Daily Load for the freshwater segment of Black Creek is 400 counts/100mL for fecal coliform, and is allocated as follows:

    442(a) The Wasteload Allocation for discharges subject to the Department’s National Pollutant Discharge Elimination System Municipal Stormwater 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;

    490(b) The Load Allocation 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 percent reduction at sources contributing to exceedances of the criteria; and,

    541(c) The Margin of Safety is implicit;

    548(d) While the LA and WLA for fecal coliform have been expressed as the percent reductions needed to attain the applicable Class III criteria, it is the combined reductions from both anthropogenic point and nonpoint sources that will result in the required reduction of in-stream fecal concentration. However, it is not the intent of the TMDL to abate natural background conditions.

    609(3) North Ochlockonee River Planning Unit. Swamp Creek TMDLs. The Total Maximum Daily Load for Swamp Creek is 400 counts/100mL for fecal coliform, and is allocated as follows:

    637(a) The Wasteload Allocation for discharges subject to the Department’s National Pollutant Discharge Elimination System Municipal Stormwater 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 percent reduction at sources contributing to exceedances of the criteria;

    699(b) The Load Allocation 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 percent reduction at sources contributing to exceedances of the criteria; and,

    750(c) The Margin of Safety is implicit;

    757(d) While the LA and WLA for fecal coliform have been expressed as the percent reductions needed to attain the applicable Class III criteria, it is the combined reductions from both anthropogenic point and nonpoint sources that will result in the required reduction of in-stream fecal concentration. However, it is not the intent of the TMDL to abate natural background conditions.

    818(4) Lake Tallavana. The nutrient Total Maximum Daily Load (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 annual geometric mean chlorophyll 861a 862criterion for high color lakes, and is allocated as follows:

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

    882(b) The WLA for discharges subject to the department’s NPDES Municipal Separate Storm Sewer System (MS4) Permitting Program is not applicable,

    903(c) The Load Allocation (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, and

    932(d) The Margin of Safety is implicit.

    939(e) While the LA and WLA for TN and TP has been expressed as the percent reduction needed to attain the applicable Class III nutrient criteria, it is the combined reductions from both anthropogenic point and nonpoint sources that will result in the restoration of nutrient conditions in the impaired waterbody. However, it is not the intent of this TMDL to abate natural background conditions.
