PART IV - EVALUATION AND RECOMMENDATIONS The Town of Spruce Pine has

proposing to discharge this to Beaver Creek which is classified C-trout
waters.
Ultimate disposal of the thickened solids will be discharged from
the thickener to the Town of Spruce Pine's existing wastewater
treatment facility.
It does not appear that this wastewater will violate water quality
