  • 1(1) Spruce Creek (Freshwater Segment). The 7bacteriological TMDL 9for the freshwater segment of Spruce Creek is 400 counts/100mL for fecal coliform, and is allocated as follows:

    27(a) The WLA for discharges subject to the Department’s NPDES MS4 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 1997 to 2005 period, will require a 53% reduction at sources contributing to exceedances of the criteria; and

    83(b) 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 1997 to 2005 period, will require a 53% reduction at sources contributing to exceedances of the criteria.

    131(2) Spruce Creek (Marine Segment). 136The TMDL for the marine segment of Spruce Creek is based on achieving the Class 3 marine minimum DO criterion of 4.0 mg/L, and is allocated as follows:
