Fla. Admin. Code Ann. R. 62-304.435 - Upper East Coast Basin TMDLs
(1)
Spruce Creek (Freshwater Segment). The bacteriological TMDL for the freshwater
segment of Spruce Creek is 400 counts/100mL for fecal coliform, and is
allocated as follows:
(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
(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.
(2) Spruce Creek (Marine Segment). The 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:
(a) The WLA for discharges subject to the
Department's NPDES MS4 Permitting Program is a 25% reduction of current
anthropogenic BOD loading, and a 27% reduction of current anthropogenic TP
loading based on measured concentrations from the 1992 to 2005 period;
and
(b) The LA for nonpoint sources
is a 25% reduction of current anthropogenic BOD loading, and a 27% reduction of
current anthropogenic TP loading based on measured concentrations from the 1992
to 2005 period.
(3)
Pellicer Creek. The bacteriological TMDL for Pellicer Creek is 43 counts/100mL

(a) The WLA for wastewater point sources is
not applicable;
(b) The WLA for
discharges subject to the Department's NPDES MS4 Permitting Program is not
applicable; and
(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 2004, 2005, and 2009, will require a 94% reduction
of sources contributing to exceedances of the criteria.
(4) Tomoka River (Fresh Water Segment). The
TMDL to address the nutrient impairment in the freshwater segment of Tomoka

respectively, and is allocated as follows:
(a)
The WLA for wastewater point sources is not applicable;
(b) The WLA for discharges subject to the
Department's NPDES Permitting Program (MS4) is a 30% reduction of current
anthropogenic TN loading, and a 30% reduction of current anthropogenic TP
loading based on measured concentrations from the 1992 to 2011 period;
and
(c) The LA for nonpoint sources
is a 30% reduction of current anthropogenic TN and TP loadings based on
measured concentrations from the 1992 to 2011 period.
(5) Halifax River (Northern Segment). The
TMDL to address the nutrient impairment in the northern segment of Halifax
River is an annual average TN and TP concentration of 1.13 mg/L and 0.185 mg/L,
respectively, and is allocated as follows:
(a)
The WLA for the Ormond Beach Wastewater Treatment Facility (WWTF) is 109, 666
lbs TN/yr and 18, 278 lbs TP/yr. The WLA for the Holly Hill WWTF is 21, 933 lbs
TN/yr and 7, 311 lbs TP/yr. The WLA for the Daytona Beach/Bethune Point WWTF is
182, 777 lbs TN/yr and 60, 926 lbs TP/yr;
(b) The WLA for discharges subject to the
Department's NPDES MS4 Permitting Program (MS4) is a 9% reduction of current
anthropogenic TN loading based on measured concentrations from the 1995 to 2010
period; and
(c) The LA for nonpoint
sources is a 9% reduction of current anthropogenic TN loading, based on
measured concentrations from the 1995 to 2010 period.
(6) South Matanzas River (from the City of
Palm Coast to the northern portions of Flagler Beach). The TMDL to address the
nutrient impairment in the South Matanzas River from the City of Palm Coast to
the northern portions of Flagler Beach is an annual TN and TP load of 807, 418
lbs TN/yr and 86, 685 lbs TP/yr, and is allocated as follows:
(a) The WLA for the Palm Coast WWTF#1 is 111,
190 lbs TN/yr and 30, 466 lbs TP/yr. The WLA for the Palm Coast WWTF #2
facility is WLA is 6, 483 lbs TN/yr and 1, 625 lbs TP/yr. The WLA for Beverly
Beach WWTF is 4, 606 lbs TN/yr and 503 lbs TP/yr. The WLA for the Dunes
CDD-Reverse Osmosis Concentrate facility is 1, 531 lbs TN/yr and 323 lbs
TP/yr;
(b) The WLA for discharges
subject to the Department's NPDES MS4 Permitting Program is a 29% reduction of
current anthropogenic TN and TP loadings based on measured concentrations from
the 1997 to 2009 period; and
(c)
The LA for nonpoint sources is a 29% reduction of current anthropogenic TN and
TP loadings based on measured concentrations from the 1997 to 2009
period.
