    62-304.335: Perdido Bay TMDLs

    PURPOSE AND EFFECT: The purpose of the rule is to adopt a Total Maximum Daily Load (TMDL), and its allocations, for fecal coliform in the Perdido Bay Basin.

    SUMMARY: The TMDL addresses a fecal coliform impairment in the Perdido Bay Basin. Specifically, the TMDL rule being proposed for adoption is for Brushy Creek. This waterbody was verified as impaired using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters. The methodology used to develop the TMDL was the percent reduction method. This rulemaking has been given an OGC case number 12-1172.

    SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS AND LEGISLATIVE RATIFICATION:

    The Agency has determined that this will not have an adverse impact on small business or likely increase directly or indirectly regulatory costs in excess of $200,000 in the aggregate within one year after the implementation of the rule. A SERC has not been prepared by the agency.

    The Agency has determined that the proposed rule is not expected to require legislative ratification based on the statement of estimated regulatory costs or if no SERC is required, the information expressly relied upon and described herein: There are no regulated entities, including NPDES permitted wastewater and municipal stormwater facilities, located in the Brushy Creek watershed.

    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.

    RULEMAKING AUTHORITY: 403.061, 403.067 FS.

    LAW IMPLEMENTED: 403.061, 403.062, 403.067 FS.

    DATE AND TIME: September 27, 2012, 1:30 p.m.

    THE FULL TEXT OF THE PROPOSED RULE IS:

    62-304.335 Perdido Bay Basin TMDLs.

    (1) Fecal Coliform TMDL for Elevenmile Creek (US 90). The Total Maximum Daily Load is 400 counts/100 ml and is allocated as follows:

    (a) The Wasteload Allocation (WLA) for wastewater point sources subject to the Department’s National Pollutant Discharge Elimination System (NPDES) Permitting Program is to meet the Class III water quality criteria for fecal coliform in Chapter 62-302, F.A.C.,

    (b) The WLA 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 1972 to 2006 period, will require a 63 percent reduction at 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 the 1972 to 2006 period, will require a 63 percent reduction at sources contributing to exceedances of the criteria,

    (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 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) Fecal Coliform TMDL for Elevenmile Creek (State Road 297A). The Total Maximum Daily Load is 400 counts/100 ml and is allocated as follows:

    (a) The WLA Wasteload Allocation for wastewater point sources subject to the Department’s National Pollutant Discharge Elimination System Permitting Program is to meet the Class III water quality criteria for fecal coliform in Chapter 62-302, F.A.C.,

    (b) The WLA 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 1972 to 2006 period, will require a 66 percent reduction at sources contributing to exceedances of the criteria,

    (c) The LA 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 1972 to 2006 period, will require a 66 percent reduction at sources contributing to exceedances of the criteria,

    (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 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.

    (3) Fecal Coliform TMDL for Tenmile Creek. The Total Maximum Daily Load for Fecal Coliforms for Tenmile Creek is 400 counts/100 ml and is allocated as follows:

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

    (b) The WLA 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 1972 to 2006 period, will require a 43 percent reduction at sources contributing to exceedances of the criteria,

    (c) The LA 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 1972 to 2006 period, will require a 43 percent reduction at sources contributing to exceedances of the criteria,

    (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 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.

    (4) Fecal Coliform TMDL for Brushy Creek. The TMDL for Brushy Creek is 400 counts/100mL for fecal coliform, 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 not applicable,

    (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 2004 to 2011 period, will require a 64 percent reduction of sources contributing to exceedances of the criteria, and

    (d) The Margin of Safety is implicit.

    (e) While the LA for fecal coliform has been expressed as the percent reductions needed to attain the applicable Class III criteria, it is the combined reductions from all anthropogenic 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.
