5. REMOVE ALL SOILS AND SEDIMENTS TRACKED OR
OTHERWISE DEPOSITED ONTO PUBLIC AND PRIVATE
PAVEMENT AREAS. REMOVAL SHALL BE ON A DAILY BASIS
WHEN TRACKING OCCURS.
6. LOCATE SOIL STOCKPILES NO LESS THAN FIFTY (50) FEET
FROM ANY PUBLIC OR PRIVATE ROADWAY OR DRAINAGE
CHANNEL. IF REMAINING FOR MORE THAN SEVEN DAYS,
STABILIZE THE STOCKPILES BY VEGETATIVE COVER, TARPS,
OR OTHER MEANS. CONTROL EROSION FROM ALL
STOCKPILES BY PLACING SILT BARRIERS AROUND THE PILES
TEMPORARY STOCKPILES LOCATED ON PAVED SURFACES
MUST BE NO LESS THAN FIVE FEET FROM THE
DRAINAGE/GUTTER LINE AND SHALL BE COVERED IF LEFT
MORE THAN 24 HOURS.
7. MAINTAIN ALL TEMPORARY EROSION AND SEDIMENT
CONTROL DEVICES IN PLACE UNTIL THE CONTRIBUTING
DRAINAGE AREA HAS BEEN STABILIZED. INSPECT
TEMPORARY EROSION AND SEDIMENT CONTROL DEVICES ON
A DAILY BASIS AND REPLACE DETERIORATED, DAMAGED, OR
ROTTED EROSION CONTROL DEVICES IMMEDIATELY.
8. TEMPORARILY OR PERMANENTLY STABILIZE ALL DENUDED
AREAS WHICH HAVE BEEN FINISH GRADED, AND ALL
DENUDED AREAS IN WHICH GRADING OR SITE BUILDING
CONSTRUCTION OPERATIONS ARE NOT ACTIVELY UNDERWAY
AGAINST EROSION DUE TO RAIN, WIND AND RUNNING WATER
WITHIN 14 DAYS. USE SEEDING AND MULCHING, EROSION
CONTROL MATTING, AND/OR SODDING AND STAKING IN
GREEN SPACE AREAS AND OTHERWISE APPROPRIATE
MEASURES. USE EARLY APPLICATION OF GRAVEL BASE ON
AREAS TO BE PAVED.
9. DO NOT REMOVE ANY EROSION AND SEDIMENT CONTROL
DEVICES AFTER THE PROTECTED AREA HAS UNDERGONE
FINAL STABILIZATION AND PERMANENT VEGETATION HAS
BEEN ESTABLISHED, IT IS RECOMMENDED THAT NCDEQ
APPROVE THE ACTION PRIOR TO REMOVAL.
10. THE CONSTRUCTION ENTRANCE SHALL BE INSTALLED
CONCURRENTLY WITH THE INITIATION OF CONSTRUCTION
ACTIVITY.
11. THE INSTALLATION OF EROSION CONTROL MEASURES SHALL
TAKE PRECEDENCE OVER ALL OTHER CONSTRUCTION
ACTIVITIES.
12. THE PERMITTEE SHALL BE HELD RESPONSIBLE FOR THE
ACTIONS AND PERFORMANCE OF ANY OTHER PARTIES
PERFORMING WORK ON THIS PROJECT.
13. ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE
CHECKED FOR STABILITY AND OPERATION FOLLOWING EVERY
RUNOFF -PRODUCING RAINFALL BUT IN NO CASE LESS THAN
ONCE EVERY WEEK. ANY NEEDED REPAIRS WILL BE MADE
IMMEDIATELY TO MAINTAIN ALL PRACTICES AS DESIGNED.
14. PURSUANT TO G.S. 113A-57(2), THE ANGLE FOR GRADED
SLOPES AND FILLS SHALL BE NO GREATER THAN THE
ANGLE THAT CAN BE RETAINED BY VEGETATIVE COVER OR
OTHER ADEQUATE EROSION CONTROL DEVICES OR

NOTIFICATION 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, DWQ AND DEMLR
DEVELOPED A COMBINED FORM. 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 SHOULD BE CONDUCTED AFTER EACH PHASE OF
THE PROJECT, AND CONTINUED UNTIL PERMANENT GROUND
COVER IS ESTABLISHED. THE FORM CAN BE ACCESSED AT:
HTTP: //PORTAL.NCDENR.ORG/WEB/LR/EROSION
IF YOU HAVE QUESTIONS OR CANNOT ACCESS THE FORM,
PLEASE CONTACT THE FAYETTEVILLE REGIONAL OFFICE AT (910)
433-3300.
STRUCTURES. IN ANY EVENT, SLOPES LEFT EXPOSED WILL,
WITHIN 7 OR 14 CALENDAR DAYS OF COMPLETION OF ANY
PHASE OF GRADING, BE PLANTED OR OTHERWISE PROVIDED
WITH TEMPORARY OR PERMANENT GROUND COVER, DEVICES
OR STRUCTURES SUFFICIENT TO RESTRAIN EROSION.
PURSUANT TO G.S. 113A-57(3), PROVISIONS FOR
PERMANENT GROUND COVER SUFFICIENT TO RETAIN EROSION
MUST BE ACCOMPLISHED FOR ALL DISTURBED AREAS WITHIN
90 CALENDAR DAYS FOLLOWING COMPLETION OF
CONSTRUCTION OR DEVELOPMENT.
15. CONTRACTOR IS RESPONSIBLE FOR INSTALLING ALL EROSION
CONTROL MEASURES SHOWN AND ANY ADDITIONAL
MEASURES REQUIRED TO CONTROL THE SEDIMENT DURING
THE COURSE OF CONSTRUCTION.
16. ALL SEEDED AREAS WILL BE FERTILIZED, RESEEDED AS
NECESSARY, AND MULCHED ACCORDING TO THE DETAILS
HEREIN.
17. THE CONTACT PERSON FOR EROSION CONTROL ISSUES THAT
ARISE ON SITE IS SANJAY KHAZANCHI. CONTACT
