E. coli Data Geometric mean calculated for each site – All 15 sites reported as not meeting the standard in 2010 Highest geometric mean = 2214.3 – Site WLV160-0038 Lowest geometric mean = 543.13 – Site WLV160-0035 Highest single sample = 2419.6 – Every site Lowest single sample = 191.8 – Site WLV160-0015

18. IBI - Index of Biotic Integrity ≥ 36 (WQS) Dissolved Oxygen - ≥ 4.0 mg/L (WQS) Total Phosphorus - ≤ 0.30 mg/L (U.S. EPA) Total Suspended Solids - ≤ 30.0 mg/L (IN NPDES permitting) Impaired Biological Communities (IBC) Results

20. Allowable Loads

21. The Definition of a TMDL The sum of allowable loads from point sources, waste load allocations (WLA) and nonpoint sources, load allocations (LA) plus a margin of safety (MOS) TMDL = ∑WLA + ∑LA + MOS

22. Allocations Waste load Allocation (WLA) – WLAs are the contributions from point sources – Point sources are easier to identify since they have a discharge point or direct outlet to the stream – Point sources have some type of monitoring or information and are therefore easier to assign loadings

23. Allocations Load Allocation (LA) – LAs are the pollutant contributions from nonpoint sources, which are not directly regulated – "Diffuse" pollution, generated from large areas with no particular point of pollutant origin, but rather from many individual places – Pollution that cannot be traced to a regulated direct outlet or discharge point

24. Big Raccoon Creek Point Sources

25. Big Raccoon Creek Nonpoint Sources

26. TMDL Allocation Development

27. TMDL Allocations Clean Water Act requires that TMDL be allocated as follows: – TMDL = WLA + LA + MOS – Waste load allocations (WLA) for “point sources” (regulated under NPDES) – Load allocations (LA) for nonpoint sources – MOS for margin of safety

28. Big Raccoon Creek TMDL Allocations Waste load Allocations – 4 NPDES facilities with sanitary component – 1 CFO Demaree Farms Partnership: WLA= 0 – Illicitly connected on-site systems (i.e., straight pipe dischargers) are zero

29. Big Raccoon Creek TMDL Allocations Waste Load Allocations for E. coli – Advance WWTP: 0.14 (Billion/Day) – New Ross WWTP: 1.23 (Billion/Day) – Roachdale WWTP: 0.59 (Billion/Day) – Ladoga WWTP: 0.93 (Billion/Day)

30. Big Raccoon Creek TMDL Allocations Load Allocations – Agricultural Run-off – Failing Septic Systems – Livestock – Stream Bank Erosion – Urban Run-off – Wildlife

31. Allocation Development Data used to develop allocation – Precipitation National Oceanic and Atmospheric Administration (NOAA) weather station – Flow U.S. Geological Survey (USGS) Flow Gage – Modeling Using IDEM Data Spreadsheet modeling tool Traditional modeling

32. Precipitation Many sources of pollution are impacted by precipitation A path for pollutants to enter a waterbody is through rain and snow melt Information on precipitation used with the Load Duration Curve (LDC) will give a better overall sense of flow conditions in stream

34. Flow The long history of flow gages provides a valuable tool in evaluating water quality data USGS flow gages provide a consistent high quality source of flow information The large network of flow gages means that finding a representative flow gage is possible

35. Load Duration Curve IDEM Data & USGS Gage 03340800 Flow Data Upstream Drainage Area is 27.38 Square Miles Moist Conditions Dry Conditons Mid-Range Flows Low Flows High Flows

38. Implementation

39. Implementation of TMDL expected to occur via current and future activities such as: – Vegetated filter strips – Stream fencing (animal exclusion) – Control of failing septic systems – Conservation tillage – Urban conservation practices – Additional agricultural conservation practices
