TMDL Pollutant: Biology
| Total Waste Load Allocation: | .133 | Total Load Allocation: | 1.6 | |
| Explicit Margin Of Safety: | Implicit Margin Of Safety: | Y | ||
| Units for Total Waste Load Allocation and Total Load Allocation: | TONS/DAY | TMDL Pollutant Source Type: | Point/Nonpoint Source | |
| TMDL End Point: | THE LINKAGE OF THE TARGETED POLLUTANT TO THE BIOLOGICAL IMPAIRMENT IS ESTABLISHED. TO DEVELOP THIS LINKAGE THE SUBMITTAL USES THE TSS LOAD FOR A SIMILAR RIVER MEETING ITS AQUATIC LIFE USE. THE CHIKASKIA RIVER IS THE STREAM CHOSEN AS A REFERENCE AND ITS CURRENT LOAD DURATION CURVE IS THE TARGET FOR THE WOLF RIVER TMDL. THE SUBMITTAL RECOGNIZES THAT THE RELATIONSHIP BETWEEN BIOTIC INDICES AND TSS IS NOT YET QUANTIFIED AND SO THE REFERENCE APPROACH IS USED. EPA AGREES THAT THE STATED RELATIONSHIP IS AN APPROPRIATE SURROGATE MEASURE TO TARGET FOR THE ATTAINMENT OF THE BIOLOGICAL INDICES. BIOLOGIC CRITERIA FOR KANSAS STREAMS ARE BASED ON THE FOLLOWING MULTI-METRIC INDICES: MACROINVERTEBRATE BIOTIC INDEX; KANSAS BIOTIC INDEX; EPT INDEX (EPHEMEROPTERA/PLECOPTERA/TRICHOPTERA); AND % EPT ABUNDANCE. THE SUBMITTAL TARGETS ARE SET TO RESULT IN THE ATTAINMENT OF THESE INDICES. WOLF RIVER'S LC IS SET BY THE USE OF A LOAD DURATION CURVE BASED ON THE TOTAL SUSPENDED SOLIDS (TSS) CONCENTRATIONS MEASURED AT VARIOUS PERCENTILES OF FLOW IN A PAIRED REFERENCE STREAM TO ADDRESS THE SUSPENDED SOLIDS NARRATIVE STANDARD. THE TSS TARGET IS USED BECAUSE OF THE EFFECT EXCESS SEDIMENT DEPOSITION HAS ON MACROINVERTEBRATES WHICH USE COARSE SUBSTRATES. AT MEDIAN FLOW (50TH PERCENTILE OF FLOW EXCEEDANCE) THE LC IS 1.7 TONS OF TSS, A REDUCTION OF 2.8 TONS FOR THAT FLOW. | |||
