TMDL Pollutant: Escherichia Coli (E. Coli)

Total Waste Load Allocation:      Total Load Allocation:
Explicit Margin Of Safety:      Implicit Margin Of Safety: Y
Units for Total Waste Load Allocation and Total Load Allocation:      TMDL Pollutant Source Type: Point/Nonpoint Source
TMDL End Point: ANALYSIS/METHODOLOGY - THE TMDLS FOR IMPAIRED WATERBODIES IN THE CANEY FORK WATERSHED WERE DEVELOPED USING THE LOAD DURATION CURVE METHODOLOGY TO ASSURE COMPLIANCE WITH THE E. COLI 126 COUNTS/100 ML GEOMETRIC MEAN AND 941 COUNTS/100 ML MAXIMUM STANDARDS WHILE ALSO INCORPORATING THE FECAL COLIFORM 200 COUNTS/100 ML GEOMETRIC MEAN AND 1,000 COUNTS/100 ML MAXIMUM CONCENTRATION AS SURROGATES. A DURATION CURVE IS A CUMULATIVE FREQUENCY GRAPH THAT REPRESENTS THE PERCENTAGE OF TIME DURING WHICH THE VALUE OF A GIVEN PARAMETER IS EQUALED OR EXCEEDED. LOAD DURATION CURVES ARE DEVELOPED FROM FLOW DURATION CURVES AND CAN ILLUSTRATE EXISTING WATER QUALITY CONDITIONS (AS REPRESENTED BY LOADS CALCULATED FROM MONITORING DATA), HOW THESE CONDITIONS COMPARE TO DESIRED TARGETS, AND THE PORTION OF THE WATERBODY FLOW REGIME REPRESENTED BY THESE EXISTING LOADS. LOAD DURATION CURVES WERE USED TO DETERMINE THE LOAD REDUCTIONS REQUIRED TO MEET THE TARGET MAXIMUM CONCENTRATIONS FOR E. COLI AND FECAL COLIFORM (STANDARD - MOS). WHEN SUFFICIENT DATA WERE AVAILABLE, LOAD REDUCTIONS WERE ALSO DETERMINED BASED ON GEOMETRIC MEAN CRITERIA. CRITICAL CONDITIONS - WATER QUALITY DATA COLLECTED OVER A PERIOD OF 10 YEARS FOR LOAD DURATION CURVE ANALYSIS WERE USED TO ASSESS THE WATER QUALITY STANDARDS REPRESENTING A RANGE OF HYDROLOGIC AND METEOROLOGICAL CONDITIONS. SEASONAL VARIATION - THE 10-YEAR PERIOD USED FOR LSPC MODEL SIMULATION PERIOD AND FOR LOAD DURATION CURVE ANALYSIS INCLUDED ALL SEASONS AND A FULL RANGE OF FLOW AND METEOROLOGICAL CONDITIONS. MARGIN OF SAFETY (MOS) - EXPLICIT ¿ 10% OF THE WATER QUALITY STANDARD FOR EACH IMPAIRED SUBWATERSHED.
