Full nutrient removal of TN and TP will not be available, at the future facility, before the effluent releases into the Gallatin River

Response

The author should define “full nutrient removal”. The MBR design will qualify as Enhanced Nutrient Removal (ENR), and this will be implemented well before the potential outfall were to be constructed and operated. It is extremely rare, costly, energy and chemical intensive to go beyond ENR, and there is no need to do this in Big Sky, based on the preliminary permitting evaluation.
