WILL ONLY BE ALLOWED ONCE THE SITE HAS BEEN DEEMED STABLE BY THE EROSION
CONTROL INSPECTOR. INSTALL PROTECTION AROUND ALL INLETS AS STORM DRAIN
SYSTEM IS INSTALLED.
19. ONCE PERMANENT DIVERSIONS ARE IN PLACE, TEMPORARY DIVERSION BERMS CAN BE
REMOVED. SILT FENCE ALONG PERIMETER SHALL CONTINUED TO BE MAINTAINED.
20. CONTINUE TO MAINTAIN EROSION CONTROL MEASURES UNTIL VEGETATIVE COVER HAS
BEEN ESTABLISHED OVER ALL DISTURBED AREAS AND SITE HAS BEEN STABILIZED.
REMOVE EROSION CONTROL MEASURES ONLY AFTER FINAL INSPECTION AND APPROVAL
BY INSPECTOR, EXCEPT FOR THOSE PROTECTING AREAS DOWNSTREAM OF THE SEDIMENT
BASIN.
21. AFTER SITE STABILIZATION, OBTAIN FINAL EROSION CONTROL INSPECTION TO CLOSE THE
GRADING PERMIT.
22. FILE NOTICE OF TERMINATION WITH NCDEQ TO CLOSE THE NPDES NCGO1 PERMIT.
22.1. NOTE: IF ADDITIONAL PLANS HAVE BEEN SUBMITTED AND APPROVED SHOWING
ADDITIONAL WORK, PERMIT CLOSURE PROCESS WILL BE SUPERSEDED BY THE
