NCDENR SELF -INSPECTION PROGRAM
THE SEDIMENTATION POLLUTION CONTROL ACT WAS AMENDED IN 2006 TO
REQUIRE THAT PERSONS RESPONSIBLE FOR LAND -DISTURBING ACTIVITIES
INSPECT A PROJECT AFTER EACH PHASE OF THE PROJECT TO MAKE SURE
THAT THE APPROVED EROSION AND SEDIMENTATION CONTROL PLAN IS
BEING FOLLOWED.
RULES DETAILING THE DOCUMENTATION OF THESE INSPECTIONS TAKE
EFFECT OCTOBER 1, 2010.
THE SELF -INSPECTION PROGRAM IS SEPARATE FROM THE WEEKLY
SELF-MONITORING PROGRAM OF THE NPDES STORMWATER PERMIT FOR
CONSTRUCTION ACTIVITIES. THE FOCUS OF THE SELF -INSPECTION REPORT
IS THE INSTALLATION AND MAINTENANCE OF EROSION AND SEDIMENTATION
CONTROL MEASURES ACCORDING TO THE APPROVED PLAN. THE
INSPECTIONS SHOULD BE CONDUCTED AFTER EACH PHASE OF THE
PROJECT, AND CONTINUED UNTIL PERMANENT GROUND COVER IS
ESTABLISHED.
THE SELF -INSPECTION REPORT FORM IS AVAILABLE AS AN EXCEL
