♦ TC will need to evaluate the concerns identified in item number 24 of the DRMS
Review of the 2014 AHR data and the PHC (section 2 05 6 3 of the permit) regarding
surface hydrology impacts. TC will need to address the following item:
For the lower reaches of Middle Fish and Trout Creek the projected average conductivity sulfate and
TDS levels for 2009 to 2015 contained in Exhibit 32 do not appear to be reflective of the average
levels reported in the 2014 AHR. The averages reported for these parameters exceed the average
projected amounts.
TC will need to evaluate these constituents and update the PHC accordingly and
assess the negative impacts of these elevated constituent levels.
