EROSION AND SEDIMENTATION CONTROL NOTES:
RECOMMENDED SEQUENCE:
THIS EROSION AND SEDIMENTATION CONTROL PLAN WILL BE IMPLEMENTED ACCORDING TO THE

INSTALLATION ACTIVITIES:
1. OBTAIN A COPY OF THE EROSION AND SEDIMENT CONTROL PERMIT AND OTHER APPLICABLE
PERMITS TO POST ON SITE.
2. SUBMIT A PRE -DISTURBANCE NOTIFICATION TO ENGINEER TWO WEEKS PRIOR TO SITE
ACTIVITIES. ENGINEER TO INFORM NCDEQ - DIVISION OF ENERGY, MINERAL, AND LAND
RESOURCES.
3. ATTEND PRE -CONSTRUCTION CONFERENCE WITH NCDEQ, ENGINEER, AND ANY MAJOR
SUBCONTRACTORS.
4. ESTABLISH LIMITS OF DISTURBANCE, WASTE DISPOSAL LIMITS, WASTE EXCAVATION AREAS, AND
STAGING AREA. STOCKPILE AREAS SHALL BE LOCATED 50 FEET FROM ANY STREAMS/EXISTING
DRAINAGE DITCHES.
5. INSTALL TEMPORARY CONSTRUCTION ENTRANCE AS SHOWN ON PLAN SHEET C-2.
6. INSTALL SEDIMENT FENCE AT ALL LOCATIONS SHOWN ON SHEET C-2. INSTALL SILT FENCE
OUTLETS AS SHOWN ON SHEET C-2.
7. CLEAR AND GRUB AS NEED TO INSTALL (3) SEDIMENT TRAPS AS SHOWN ON SHEET C-2.
8. CLEAR AND GRUB REMAINING AREAS. SURROUND STOCKPILE AREA WITH SEDIMENT FENCE. A
SETBACK OF 5 FEET WILL BE MAINTAINED BETWEEN THE SEDIMENT FENCE AND TOE OF THE
STOCKPILE.
9. INSTALL TEMPORARY DIVERSION DITCHES AS SHOWN ON SHEET C-2.
10. REMOVE COVER SOIL, WASTE, REGRADE, AND STABILIZE 1/ ACRE AREAS, WITH NO MORE THAN
1/ ACRE EXPOSED AT ANY TIME. UPON COMPLETION OF EACH AREA, PROCEED TO NEXT.
11. THERE SHALL BE NO EXPOSED WASTE DURING NON -WORKING HOURS AND DURING RUNOFF
PRODUCING EVENTS; EXPOSED WASTE AT THE END OF THE WORK DAY SHALL BE PROTECTED
BY TARPING OR OTHER METHOD.
12. UPON COMPLETION OF WASTE REMOVAL AND PROTECTIVE COVER SYSTEM INSTALLATION
ACTIVITIES WITHIN AN AREA, SEED AND PLACE HYDRAULICALLY APPLIED EROSION CONTROL
MEDIUM BEFORE CONTINUING EXCAVATION.
13. AFTER THE SITE IS STABILIZED, ENGINEER WILL SUBMIT A POST -STABILIZATION NOTIFICATION
TO THE NCDEQ - DIVISION OF ENERGY, MINERAL, AND LAND RESOURCES. ALL REMAINING
TEMPORARY EROSION CONTROL MEASURES WILL BE REMOVED ONCE INSPECTOR FINDS THE
SITE TO BE APPROPRIATELY STABILIZED.

MAINTENANCE PLAN:
MAINTENANCE OF THE EROSION AND SEDIMENTATION CONTROL MEASURES SHALL BE
PERFORMED THROUGHOUT THE DURATION OF THE PROJECT. ALL REPORTING, INSPECTING,
AND RECORD KEEPING IN THE RESPONSIBILITY OF THE CONTRACTOR. THE FOLLOWING
MINIMUM MAINTENANCE ACTIVITIES SHALL BE REQUIRED DURING CONSTRUCTION:
1. ALL EROSION AND SEDIMENTATION CONTROL PRACTICES (DEVICES) SHALL BE
CHECKED FOR STABILITY AND OPERATION FOLLOWING EVERY RUN-OFF PRODUCING
RAINFALL, BUT IN NO CASE LESS THAN ONCE PER WEEK. ANY NEEDED REPAIR
SHALL BE MADE IMMEDIATELY TO MAINTAIN ALL PRACTICES AS DESIGNED.
2. TEMPORARY CONSTRUCTION ENTRANCES SHALL BE DRESSED WITH 2 -INCH -DIAMETER
STONE PERIODICALLY TO PREVENT SEDIMENT FROM LEAVING THE CONSTRUCTION SITE.
3. ACCUMULATED SEDIMENT AND DEBRIS SHALL BE REMOVED FROM CLOTH AND GRAVEL
INLET DEVICES. EXTREME CARE SHALL BE TAKEN NOT TO DAMAGE OR UNDERCUT
THE WIRE MESH DURING SEDIMENT REMOVAL. FOLLOWING CLEANING ACTIVITIES,
STONE SHALL BE REPLACED AS NECESSARY.
4. SEDIMENT SHALL BE REMOVED FROM BEHIND SEDIMENT FENCES, WHEN IT BECOMES
ABOUT 1h FOOT DEEP AT THE FENCE. THE SEDIMENT FENCE SHALL BE REPAIRED
AS NECESSARY TO MAINTAIN A BARRIER.
5. SEDIMENT SHALL BE REMOVED FROM CHANNELS WHEN THE LEVEL OF SEDIMENT
ACCUMULATES TO 1/2 THE DESIGN DEPTH AND UPON COMPLETION OF THE WORK.
FOLLOWING CLEANING ACTIVITIES, ALL DISTURBED AREAS SHALL BE STABILIZED.
6. EROSION CONTROL MATTING SHALL BE CHECKED PERIODICALLY TO ENSURE THAT
CLOSE CONTACT WITH THE GROUND IS MAINTAINED AND EROSION HAS NOT
OCCURRED BENEATH THE DEVICE. ANY AREAS OF THE EROSION CONTROL MATTING
THAT HAVE BEEN DAMAGED OR NOT IN CLOSE CONTACT WITH THE GROUND SHALL BE
REPAIRED. SEE THE SEQUENCE OF CONSTRUCTION IN THE EROSION AND
SEDIMENTATION CONTROL PERMIT FOR ADDITIONAL EROSION AND SEDIMENTATION
CONTROL DETAILS.
7. ALL SEEDED AREAS SHALL BE FERTILIZED, RE -SEEDED AS NECESSARY AND MULCHED
ACCORDING TO THE SPECIFICATIONS IN THE VEGETATION PLAN TO MAINTAIN A
VIGOROUS, DENSE VEGETATIVE COVER. IF WASHOUT OCCURS, REPAIR THE SLOPE
GRADE.
8. CONTRACTOR IS RESPONSIBLE FOR COORDINATING ALL INSPECTION, RECORDS, AND
DAILY REPORTS.
