14. UPON STABILIZATION OF THE SITE, UPON APPROVAL OF THE EROSION CONTROL
INSPECTOR, DIVERSION BERMS, SILT FENCE, AND DONUT INLET PROTECTION SHALL BE
REMOVED. SEDIMENT TRAPS AND BASINS SHALL BE FILLED. AREAS DISTURBED IN
THIS PROCESS SHALL BE STABILIZED.
15. FOLLOWING STABILIZATION OF SITE, REQUEST CLOSURE OF THE GRADING PERMIT FROM
THE NCDEQ EROSION CONTROL INSPECTOR.
EROSION CONTROL NOTES
1. THE CONTRACTOR SHALL MAINTAIN CLOSE CONTACT WITH THE EROSION
CONTROL INSPECTOR. ADDITIONAL EROSION CONTROL MEASURES MAY BE
REQUIRED THAT ARE NOT INDICATED ON THE PLANS BY THE EROSION CONTROL
INSPECTOR. IT IS THE CONTRACTOR'S RESPONSIBILITY TO MAINTAIN EROSION
ONSITE, REGARDLESS OF THE MEASURES REQUIRED. ANY CHANGE IN THE
EROSION CONTROL MEASURES AND/OR GRADING SHALL BE CALLED TO THE
ATTENTION OF THE ENGINEER AND THE EROSION CONTROL INSPECTOR.
ALL MEASURES MUST REMAIN OPERABLE UNTIL THE SITE IS STABILIZED.
2. EROSION CONTROL DEVICES SHALL BE DILIGENTLY MAINTAINED THROUGHOUT
CONSTRUCTION. DEVICES SHALL BE INSPECTED AND REPAIRED AFTER EACH
SIGNIFICANT RAINFALL.
3. SEDIMENT TRAPS/BASINS ARE TO BE CLEANED OUT WHEN THE BASIN IS NO
MORE THAN HALF FULL. THEY SHALL BE CLEARED OF ALL SILT AND RESHAPED

MUST BE STABILIZED PRIOR TO REMOVAL OF EROSION CONTROL DEVICES. ONCE
THIS OCCURS, REMOVE SEDIMENT GRADE TO FINAL ELEVATIONS AND STABILIZE.
7. REMOVE EROSION CONTROL DEVICES ONLY UPON RECEIPT OF APPROVAL
FROM EROSION CONTROL INSPECTOR.
8. IF FILL MATERIALS ARE TO BE BROUGHT ONTO THIS PROJECT OR WASTE
MATERIALS ARE TO BE TAKEN FROM THIS PROJECT, THIS INFORMATION MUST BE
