| TMDL End Point: | DERIVED FROM STATE OF TENNESSEE WATER QUALITY STANDARDS, CHAPTER 1200-4-3, GENERAL WATER QUALITY CRITERIA, JANUARY, 2004 FOR RECREATION USE CLASSIFICATION (MOST STRINGENT): THE CONCENTRATION OF THE E. COLI GROUP SHALL NOT EXCEED 126 COLONY FORMING UNITS PER 100 ML, AS A GEOMETRIC MEAN BASED ON A MINIMUM OF 5 SAMPLES COLLECTED FROM A GIVEN SAMPLING SITE OVER A PERIOD OF NOT MORE THAN 30 CONSECUTIVE DAYS WITH INDIVIDUAL SAMPLES BEING COLLECTED AT INTERVALS OF NOT LESS THAN 12 HOURS. FOR THE PURPOSES OF DETERMINING THE GEOMETRIC MEAN, INDIVIDUAL SAMPLES HAVING AN E. COLI CONCENTRATION OF LESS THAN 1 PER 100 ML SHALL BE CONSIDERED AS HAVING A CONCENTRATION OF 1 PER 100 ML. IN ADDITION, THE CONCENTRATION OF THE E. COLI GROUP IN ANY INDIVIDUAL SAMPLE TAKEN FROM A LAKE, RESERVOIR, STATE SCENIC RIVER, OR TIER II OR III STREAM (1200-4-3-.06) SHALL NOT EXCEED 487 COLONY FORMING UNITS PER 100 ML. THE CONCENTRATION OF THE E. COLI GROUP IN ANY INDIVIDUAL SAMPLE TAKEN FROM ANY OTHER WATERBODY SHALL NOT EXCEED 941 COLONY FORMING UNITS PER 100 ML. AT THE TIME OF THIS TMDL ANALYSIS, HIGH QUALITY WATERS WERE DESIGNATED AS TIER II AND TIER III STREAMS. THE PROPOSED REVISED WATER QUALITY STANDARDS REDEFINE HIGH QUALITY WATERS AS EXCEPTIONAL TENNESSEE WATERS. | |||
