authorized consultant, Agri -Waste Technology, Inc., intends to upgrade/install a wastewater treatment
system designed to discharge to Surface Waters of the State in accord with plans and specifications signed
by the engineer on March 9, 2022. Compliance under General Permit NCG550000 restricts discharge
flow, not to exceed 1,000 gallons per day. This ATC covers treatment facilities for a three (3)-bedroom
