62-304.300: St. Marks Basin TMDLs
PURPOSE AND EFFECT: The purpose of the rule is to adopt Total Maximum Daily Loads (TMDLs), and their allocations, for fecal coliforms in Munson Slough.
SUMMARY: These TMDLs address fecal impairment in Munson Slough, which was verified as impaired by fecal coliforms using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters. The percent reduction method was used to develop the fecal coliform TMDL.
SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS: The Department has not prepared a Statement of Estimated Regulatory Cost (SERC) for this proposed Rule.
Any person who wishes to provide information regarding a statement of estimated regulatory costs, or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.

THE FULL TEXT OF THE PROPOSED RULE IS:
62-304.300 St. Marks River Basin TMDLs.
Munson Slough TMDLs. Munson Slough TMDL for Fecal Coliform. The Total Maximum Daily Load for Munson Slough is 400 counts/100mL for fecal coliform, and is allocated as follows:
(1) 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 fecal coliform criteria which, based on the measured concentrations from the 2006 period, will require a 31.6 percent reduction at sources contributing to exceedances of the criteria at Roberts Ave., and for the 2006 period, will require a 96.9 percent reduction at sources contributing to exceedances of the criteria at Springhill Road, and for the 1992 to 2007 period, will require a 91.5 percent reduction at sources contributing to exceedances of the criteria at Capital Circle S.W.
(2) 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 the 2006 period, will require a 31.6 percent reduction at sources contributing to exceedances of the criteria at Roberts Ave., and for the 2006 period, will require a 96.9 percent reduction at sources contributing to exceedances of the criteria at Springhill Road, and for the 1992 to 2007 period, will require a 91.5 percent reduction at sources contributing to exceedances of the criteria at Capital Circle S.W.
(3) The Margin of Safety is implicit.
(4) 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.
