Fields 6, 7 and 8 have been certified and are operational. Fields IA, IB, 2, 3, 4 and 5 have not been certified by a licensed North Carolina Professional Engineer; therefore, irrigation on these fields is prohibited until certified. Accordingly, the permitted flow has been reduced to 2,170 GPD based on the annual loading rate for Fields 6, 7 and 8. Once an Engineering Certification and a startup inspection has been completed for Fields IA, 1B, 2, 3, 4 and 5, then the permitted flow will increase to the original permitted rate of 5,360 GPD.
