The conservation letter references “disposal of at least 160 mgy” (million gallons per year).


As stated on multiple occasions and in the CDR, There is no intent to dispose of 160 mgy annually to the Gallatin. This is an approximate, proposed discharge permitting goal, to cover potential emergency discharges in the event of a reuse pipeline or large reservoir failure. The estimated need for disposal to the Gallatin River, if needed and at full build-out of the District, is 70 mgy (See Figure 2 of the Executive Summary).
