TMDL Document for CHETOLAH CREEK (BCTP)
| TMDL ID: | 41247 | TMDL Name: | CHETOLAH CREEK (BCTP) | ||
| State/Tribe: | Kansas | TMDL Date: | 09/28/2011 | ||
| EPA Action: | EPA Approved | Comments: | "NOTE FOR POLLUTANT TOTAL PHOSPHORUS(515): THE MOS IS IMPLICIT DUE TO CONSERVATIVE ASSUMPTIONS PROVIDING ASSURANCE THAT FUTURE WLA WILL NOT CAUSE FURTHER DEFERMENT FROM THE NUTRIENT CRITERIA. 1) DESIGN FLOWS ARE USED FOR THE FOUR POINT SOURCE DISCHARGERS TO SET WLA. 2) WLA FOR ELLIS AND WAKEENEY ARE ASSUMED TO TRAVEL THROUGH BIG CREEK AND ARRIVE AT HAYS. 3) BIOLOGICAL ENDPOINTS ARE USED TO ASSESS THE NARRATIVE CRITERIA AND HAVE TO BE MAINTAINED FOR THREE CONSECUTIVE YEARS BEFORE ATTAINMENT OF WQS CAN BE CLAIMED. 4) THERE IS OFTEN A SYNERGISTIC EFFECT OF TP AND NITROGEN ON IN-STREAM BILOGICAL ACTIVITY, CONCURRENT EFFORTS BY HAYS TO REDUCE NITROGEN CONTENT OF ITS WASTEWATER SHOLD COMPLEMENT THE EFFECT OF TP LOAD REDUCTION IN IMPROVING THE BIOLOGICAL CONDITION OF BIG CREEK. 74.70 LB/DAY IS THE TOTAL (ALL THREE PHASES) LA FOR THE THREE WWTF & CITH OF HAYS. THE WLA FOR HAYS' MS4 PERTAINS TO SEGMENT 3 ONLY. AT 50 PERCENT FLOW EXCEEDANCE, THE WLA AT PHASE 1, II AND II ARE 0.61 LBS/DAY, 0.22 LBS/DAY AND .022 LBS/DAY, CONSECUTIVELY. REFER TO TMDL FOR SPECIFIC WLA FOR EACH SEGMENT/PHASE. 41.40 LBS/DAY IS THE TOTAL LA FOR ALL THREE SEGMENTS AND ALL THREE PHASES. THE WLA ARE AT 50 PERCENT FLOW EXCEEDANCE. REFER TO TMDL FOR SPECIFIC WLA FOR EACH SEGMENT/PHASE." | ||

| TMDL End Point: |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| |||
