  • Rule No.: RULE TITLE
    62-304.600: Tampa Bay Basin TMDLs
    NOTICE OF CHANGE
    Notice is hereby given that the following changes have been made to the proposed rule in accordance with subparagraph 120.54(3)(d)1., F.S., published in Vol. 36 No. 17, April 30, 2010 issue of the Florida Administrative Weekly.

    62-304.600 Tampa Bay Basin TMDLs.

    (1) Allen Creek (tidal). The fecal coliform TMDL for Allen Creek (tidal) is 43 400 counts/100mL and is allocated as follows:

    (a) The Wasteload Allocation (WLA) for wastewater sources is not applicable,

    (b) The 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 fecal coliform criteria which, based on the measured concentrations from 2000 to 2007 2008, will require a 71 77 percent reduction of sources contributing to exceedances of the criteria,

    (c) The Load Allocation (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 2000 to 2007 2008, will require a 71 77 percent reduction of sources contributing to exceedances of the criteria, and

    (d) The Margin of Safety is implicit.

    (e) While the LA and WLA for fecal coliform have been expressed as the percent reductions needed to attain the applicable Class II 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.

    (2) through (8) No change.

    (9) Cross Canal (North). The fecal coliform TMDL for Cross Canal (North) is 43 400 counts/100mL, 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 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 2005 to 2007 period, will require a 81 64 percent reduction of sources contributing to exceedances of the criteria,

    (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 2005 to 2007 period, will require a 81 64 percent reduction of sources contributing to exceedances of the criteria, and

    (d) The Margin of Safety is implicit.

    (e) While the LA and WLA for fecal coliform has been expressed as the percent reductions needed to attain the applicable Class II 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.

    (10) Double Branch. The fecal coliform TMDL for Double Branch is 43 400 counts/100mL, and is allocated as follows:

    (a) The WLA for the Hillsborough County Northwest Regional Wastewater Reclamation Facility (FL0041670) is that it must meet the its NPDES permit conditions,

    (b) The WLA 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 2000 to 2007 period, will require a 84 41 percent reduction of sources contributing to exceedances of the criteria,

    (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 2000 to 2007 period, will require a 84 41 percent reduction of sources contributing to exceedances of the criteria, and

    (d) The Margin of Safety is implicit.

    (e) While the LA and WLA for fecal coliform have been expressed as the percent reductions needed to attain the applicable Class II 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.

    (11) No change.

    (12) Lower Rocky Creek. The fecal coliform TMDL for Lower Rocky Creek is 43 400 counts/100mL, 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 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 2000 to 2007 period, will require a 83 71 percent reduction of sources contributing to exceedances of the criteria,

    (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 2000 to 2007 period, will require a 83 71 percent reduction of sources contributing to exceedances of the criteria, and

    (d) The Margin of Safety is implicit.

    (e) While the LA and WLA for fecal coliform have been expressed as the percent reductions needed to attain the applicable Class II 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.

    (13) through (17) No change.
