ANNOUNCEMENT OF COMBINED SELF -MONITORING AND SELF -INSPECTION FORM
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 TOOK EFFECT OCTOBER 1, 2010. TO SIMPLIFY
DOCUMENTATION OF SELF -INSPECTION REPORTS AND NPDES SELF -MONITORING REPORTS, A COMBINED FORM
IS NOW AVAILABLE. THE NEW FORM WAS DEVELOPED TO SATISFY THE REQUIREMENTS OF THE SEDIMENTATION
POLLUTION CONTROL ACT AND THE NPDES STORMWATER PERMIT FOR CONSTRUCTION ACTIVITIES, NCG 010000.
BEGINNING AUGUST 1, 2013, THE DIVISION OF ENERGY, MINERAL, AND LAND RESOURCES IS RESPONSIBLE FOR
ADMINISTERING BOTH THE SPCA AND THE NPDES STORMWATER PERMIT FOR CONSTRUCTION ACTIVITIES, NCG
010000. THE COMBINED FORM SHOULD MAKE IT EASIER TO COMPLY WITH SELF -INSPECTION REQUIREMENTS.
THE COMBINED SELF -MONITORING FORM IS AVAILABLE AS A PDF AND WORD DOCUMENT FROM THE LAND
QUALITY WEB SITE, http://portal.ncdenr.org/web/Ir/erosion
