62-304.645: Springs Coast Basin TMDLS
PURPOSE AND EFFECT: The purpose of the proposed rule is to establish the Total Maximum Daily Loads (TMDLs), and their allocations, for the Klosterman Bayou Run tidal segment and the Saint Joes Creek freshwater segment.
SUMMARY: These TMDLs address the fecal coliform bacteria impairment in the Klosterman Bayou Run tidal segment and the Saint Joes Creek freshwater segment, which were verified as impaired by fecal coliform using the methodology established in Chapter 62-303, Identification of Impaired Surface Waters, Florida Administrative Code. A discussion of each impaired water follows:
Klosterman Bayou Run tidal segment: The TMDL for Klosterman Bayou Run is for fecal coliform bacteria and was based on the “percent reduction” methodology. Under this method, the percent reduction needed to meet the applicable criterion is calculated for each measured value above the criterion, and then the median of the percent reductions is calculated to determine the percent reduction in fecal coliform loading needed for the bayou to meet the applicable water quality criteria for fecal coliform bacteria.
Saint Joes Creek freshwater segment: The TMDL for Saint Joes Creek is for fecal coliform bacteria, and was developed using the load duration method. The TMDL provides the percent reduction in fecal coliform loading needed for the creek to meet the applicable water quality criteria for fecal coliform bacteria.
SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS: The Department does not plan to prepare 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:
62-304.645
(1) Klosterman Bayou Run Tidal Segment. The Total Maximum Daily Load for Klosterman Bayou Run is 400 counts/100 ml for fecal coliform, and is allocated as follows:
(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 2005 to 2006 period, is a 52 percent reduction of current fecal coliform loading,
(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 2005 to 2006 period, is a 52 percent reduction of current fecal coliform loading, and
(c) The Margin of Safety is implicit.
(2)
(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 2004 to 2006 period, is a 50 percent reduction of current fecal coliform loading to the Saint Joes Creek Main Channel and based on the measured concentrations from the 2005 to 2006 period, is a 57 percent reduction of fecal coliform loading to the Saint Joes Creek Miles Creek tributary,
(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 2004 to 2006 period is a 50 percent reduction of current fecal coliform loading to the Saint Joes Creek Main Channel and based on the measured concentrations from the 2005 to 2006 period, is a 57 percent reduction of fecal coliform loading to the Saint Joes Creek Miles Creek tributary, and
(c) The Margin of Safety is implicit.
(d) While the Load Allocation and Wasteload Allocation 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 coliform concentrations. However, it is not the intent of the TMDL to abate natural background conditions.
