'THE SEDIMENTATION POLLUTION CONTROL ACT WAS AMENDED IN 200B TO REQUIRE THAT PERSONS RESPONSIBLE FOR LAND -DISTURBING ACTIVITIES INSPECT A PROJECT AFTER EACH PHASE OF CONSTRUCTION TO MAKE SURE THAT THE APPROVED EROSION AND SEDIMENTATION CONTROL PLAN IS BEING FOLLOWED. RULES DETAILING THE DOCUMENTATION OF THESE INSPECTIONS TOOK EFFECT OCTOBER 1, 2010.• - NCDENR DIVISION OF ENERGY, MINERAL AND LAND RESOURCES 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 MUST BE CONDUCTED AFTER EACH PHASE OF THE PROJECT AND CONTINUED UNTIL PERMANENT GROUND COVER IS ESTABLISHED IN ACCORDANCE WITH NCGS 113 .1 AND 1SA NCAC6 131. THE SELF -INSPECTION REPORT FORM IS AVAILABLE AS AN EXCEL SPREADSHEET FROM W W N-DENR.GOVNVEB/LRIEROSION.
