9. Listing Information Lower Big Blue Watershed

10. Definition of a TMDL Clean Water Act requires that a TMDL be allocated as follows: – TMDL = WLA + LA + MOS – Wasteload allocations (WLA) for “point sources” (regulated under NPDES) – Load allocations (LA) for nonpoint sources and natural background – MOS for margin of safety

11. Water Quality Standards Escherichia coli (E. coli) April 1 through October 31, E. coli shall not exceed 125 colony forming units (cfu) per 100 milliliters (mL) as a geometric mean based on not less than 5 samples equally spaced over a 30-day period nor exceed 235 cfu per 100 mL in any 1 sample in a 30-day period

12. Impaired Segments -72 Miles E. coli -15 Miles PCB Fish Tissue -8 Miles Total Mercury TMDL only addresses E. coli

13. Assessment of Water Quality 2012 listings reassessed – E. coli sampling performed by IDEM in 2010 21 sites for E. coli Sampled 5 consecutive weeks – September 20, 2010 – October 18, 2010 – 2013 East Fork White River sampling 2 sites sampled in Lower Big Blue River watershed – July 16, 2013- August 13, 2013

15. E. coli Data IDEM sampled in 2010, 2013 Geometric mean calculated for each site – 7 sites reported meeting the standard in 2010 – 14 sites reported not meeting the standard in 2010 – 2 sites reported not meeting the standard in 2013 Highest geometric mean = 1215.7 – Site 21 Lowest geometric mean = 30.16 – Site 1 Highest single sample = 2419.6 – Sites 3, 10 Lowest single sample = 10.8 – Site 1

23. Lower Big Blue River TMDL Allocations Load Allocations – Agricultural Run-off – Failing Septic Systems – Livestock – Tile Drains – Urban Run-off – Wildlife – Forested

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

25. 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
