CONTROL 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 TOOK 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 MUST BE CONDUCTED AFTER EACH PHASE OF
THE PROJECT, AND CONTINUED UNTIL PERMANENT GROUND
COVER IS ESTABLISHED IN ACCORDANCE WITH NCGS 113A -54.1
AND 15A NCAC 413.0131. THE SELF - INSPECTION REPORT FORM
IS AVAILABLE AS AN EXCEL SPREADSHEET FROM
http://www.dlr.enr.state.nc.use/pages/sedimentation—new.htmi.

1. ENSURE THAT THE SUBGRADE FOR THE FILTER A;ND RIPRAP FOLLOWS THE REQUIRED LINES AND
GRADES SHOWN ON THE PLAN. COMPACT ANY FIiLL REQUIRED IN THE SUBGRADE TO DENSITY OF THE
SURROUNDING UNDISTURBED MATERIAL. LOW AREAS IN THE SUBGRADE ON UNDISTURBED SOIL SHALL
BE FILLED BY INCREASING THE RIPRAP THICKNESS.
2. THE RIPRAP AND GRAVEL FILTER SHALL CONFORM TO THE SPECIFIED GRADING LIMITS SHOWN ON THE
PLANS.
3. FILTER CLOTH, WHEN USED, MUST MEET DESIGN !REQUIREMENTS AND BE PROPERLY PROTECTED FROM
PUNCHING OR TEARING DURING INSTALLATION. REPAIR ANY DAMAGE BY REMOVING THE RIPRAP AND
PLACING ANOTHER PIECE OF FILTER CLOTH OVER THE DAMAGED AREA. ALL CONNECTING JOINTS
SHOULD OVERLAP A MINIMUM OF 1 FOOT. IF THE DAMAGE IS EXTENSIVE, REPLACE THE ENTIRE FILTER
CLOTH.
4. RIP RAP MAY BE PLACED BY EQUIPMENT, BUT TAKE CARE TO AVOID DAMAGING THE FILTER.
5. THE MINIMUM THICKNESS OF THE RIPRAP SHOULD BE AS SPECIFIED IN THE SCHEDULE.
6. RIPRAP MAY BE FIELD STONE OR ROUGH QUARRY STONE, IT SHOULD BE HARD, ANGULAR, HIGHLY
WEATHER - RESISTANT AND WELL GRADED.
7. CONSTRUCT THE APRON ON ZERO GRADE WITH NO OVERFALL AT THE END. MAKE THE TOP OF THE
RIPRAP AT THE DOWNSTREAM END LEVEL WITH THE RECEIVING AREA OR SLIGHTLY BELOW IT.
8. ENSURE THAT THE APRON IS PROPERLY ALIGNED WITH THE RECEIVING STREAM AND PREFERABLY
STRAIGHT THROUGH ITS LENGTH. IF A CURVE IS NEEDED TO FIT SITE CONDITIONS, PLACE IT IN THE
UPPER SECTION OF THE APRON.
9. AFTER CONSTRUCTION, STABILIZE ALL DISTURBED AREAS WITH VEGETATION.
MAINTENANCE:
INSPECT RIPRAP OUTLET STRUCTURES EVERY SEVEN DAYS AND AFTER EACH RAINFALL EVENT
(1/2 INCH OR GREATER) TO SEE IF ANY EROSION AROUND OR BELOW THE RIPRAP HAS TAKEN
PLACE OR IF STONES HAVE BEEN DISLODGED. MAKiE ALL NEEDED REPAIRS TO PREVENT
FURTHER DAMAGE.

REMOVE SEDIMENT ACCUMULATED BEHIND THE DAMS AS
NEEDED TO PREVENT DAMAGE TO CHANNEL VEGETATION,
ALLOW THE CHANNEL TO DRAIN THROUGH THE STONE
CHECK DAM, AND PREVENT LARGE FLOWS FROM
CARRYING SEDIMENT OVER THE DAM. ADD STONES TO

1. PLACE STONE TO THE LINES AND DIMENSIONS SHOWN IN THE PLAN ON. A FILTER FABRIC FOUNDATION.
2. KEEP THE CENTER STONE SECTION AT LEAST 9 INCHES BELOW NATURAL GROUND LEVEL WHERE THE DAM ABUTS THE CHANNEL
BANKS.
3. EXTEND STONE AT LEAST 1.5 FEET BEYOND THE DITCH BANKS TO KEEP OVERFLOW WATER FROM UNDERCUTTING THE DAM AS IT
RE- ENTERS THE CHANNEL.
4. SET SPACING BETWEEN DAMS TO ASSURE THAT THE ELEVATION AT THE TOP OF THE LOWER DAM IS THE SAME ELEVATION AS THE TOE
ELEVATION OF THE UPPER DAM.
5. PROTECT THE CHANNEL DOWNSTREAM FROM THE LOWEST CHECK DAM, CONSIDER THAT WATER WILL FLOW OVER AND AROUND THE
DAM.
6. MAKE SURE THAT THE CHANNEL REACH ABOVE THE MOST UPSTREAM iDAM IS STABLE.
