EROSION CONTROL NOTES:
1. CONTACT THE NCDENR, LAND QUALITY SECTION (910-395 -3900) ONE WEEK PRIOR TO
LAND DISTURBING ACTIVITY, AND ONE WEEK PRIOR TO FINAL INSPECTION.
2. A COPY OF THE APPROVED SEDIMENT AND EROSION CONTROL PLAN SHALL BE MAINTAINED AT THE SITE.
3. PRIOR TO COMMENCING LAND DISTURBING ACTIVITIES IN AREAS OTHER THAN THOSE INDICATED ON THE PLANS,
BUT NOT LIMITED TO OFFSITE BORROW AND DISPOSAL AREAS, CONTRACTOR SHALL SUBMIT A SUPPLEMENTARY
EROSION CONTROL PLAN TO THE ENGINEER FOR REVIEW AND APPROVAL BY THE LAND QUALITY SECTION.
4. EROSION AND SEDIMENT CONTROL MEASURES SHALL BE INSPECTED FOR DAMAGE AND EFFECTIVE OPERATIONS*
FOLLOWING EVERY RAINFALL EVENT OR LEAST ONCE PER WEEK. REPAIRS SHALL BE COMPLETED IMMEDIATELY
TO DIMENSION AND FUNCTIONS INDICATED ON THE PLANS.
5. CONTRACTOR, RESPONSIBLE FOR INSTALLATION OF ADDITIONAL EROSION AND SEDIMENT CONTROL
MEASURES NECESSARY TO MAINTAIN EROSION AND CONTROL AS DETERMINED BY THE OWNER, ENGINEER
OR REGULATORY PERSONNEL
G. ALL DISTURBED AREAS TO DRAIN TO APPROVED SEDIMENT CONTROL MEASURES AT ALL TIMES DURING
LAND DISTURBING ACTIVITIES AND UNTIL PERMANENT STABILIZATION IS ESTABLISHED.
7. DURING DEWATERING ACTIVITIES. WATER SHALL BE PUMPED INTO AN APPROVED FILTERING
DEVICE OR DIRECTED TO EXISTING EROSION CONTROL MEASURE.
8. SEDIMENT SHALL BE REMOVED FROM BEHIND SILT FENCING WHEN IT BECOMES 0.5 FEET
DEEP AT THE FENCE. FENCE SHALL BE REPAIRED OR REPLACED AS NECESSARY TO
MAINTAIN A BARRIER.
9. ALL SEEDED AREAS SHALL BE FERTILIZED, SEEDED AND MULCHED WITHIN FIFTEEN DAYS
OF DISTURBANCE. DISTURBED AREAS SHALL BE FERTILIZED, RESEEDED
AND MULCHED AS NECESSARY ACCORDING TO CONTRACT
DOCUMENTS TO ESTABLISH AND MAINTAIN A DENSE VEGETATIVE COVER.
