NOTE: SILT FENCE TO EXTEND ALONG BOTH PERIMETER SWALES/DITCHES AND
OUTSIDE OF DETENTION POND/TST AND BELOW ANY STOCKPILE AREAS.
NOTE: ANY FILL OR BORROW MATERIAL BROUGHT ONSITE MUST BE FROM A
PERMITTED SITE AND ANY WASTE MATERIALS REMOVED FROM THE SITE MUST BE
DISPOSED OF AT A PERMITTED SITE.
CONSTRUCTION SEQUENCE:
1, OBTAIN PLAN APPROVAL BEFORE STARTING PROJECT, DO NOT START CONSTRUCTION UNTIL PLAN IS APPROVED. NOTIFY NC
DENR AT 252-945-6481 OF START DATE. .
2. INSTALL APPLICABLE E&S CONTROL MEASURES PRIOR TO ONSET OF ANY LAND DISTURBING (INCLUDING DEMOLITION) ACTIVITIES.
S. INSTALL CONSTRUCTION ENTRANCE AND PERIMETER SILT FENCE (SILT FENCE TO ALSO BE OVER AND AROUND BOTH ENDS OF
CROSSPIPE AND AS NEEDED).
4, BEGIN CLEARING ALONG PATH/DRIVE AND AREAS WHERE EROSION CONTROL MEASURES ARE SHOWN,
5. CONSTRUCT TEMPORARY SEDIMENT BASIN#1 (FUTURE STORM WATER POND) WITH SKIMMER TO APPROPRIATE DEPTH AND
DIMENSIONS INCLUDING FOREBAYS. CONSTRUCT SWALES #1, #2 & #3. EARTH BERMS ARE TO BE STABILIZED WHEN BUILT,
INSTALL SILT FENCE OVER AND AROUND PIPE INLETS AND OUTLETS. INSTALL TEMPORARY MATTING IN ALL DIVERSIONS/$WALES.
6, PROCEED WITH GRADING AND OTHER CONSTRUCTION ACTIVITIES.
7, AFTER GRADING 15 COMPLETED, TOPSOIL STOCKPILE AND WASTE AREAS TO BE REMOVED AND AREA STABILIZED.
8. WHEN CONSTRUCTION IS COMPLETE AND ALL DISTURBED AREAS ARE STABILIZED COMPLETELY, INCLUDING WASTE PILES, REMOVE
TEMPORARY MEASURES, REPLACE SKIMMER WITH SUBMERGED ORIFICE OUTLET (SEE OUTLET STRUCTURE DETAILS ON SHEET DTI)
AND REMOVE SEDIMENTS INSIDE TEMPORARY SEDIMENT BASIN #1(POND) AND COMPLETE CONSTRUCTION TO DESIGNED
DIMENSIONS.
9. GROUND COVER TO BE ESTABLISHED ON PERIMETER AREAS AND SLOPES GREATER THAN 3:1 WITHIN 7 DAYS OR SOONER
FOLLOWING COMPLETION OF ANY PHASE OF GRADING, GROUND STABILIZATION ON OTHER AREAS MUST BE WITHIN 14 DAYS.
10. ALL APPLICABLE E&S CONTROL MEASURES TO BE PROPERLY MAINTAINED UNTIL A VIGOROUS STAND OF PERMANENT VEGETATION
IS ESTABLISHED.

BUT NOT LIMITED TO THE FOLLOWING:
1, IMPLEMENT THE APPROVED EROSION AND SEDIMENTATION CONTROL PLAN AND KEEP A COPY OF THE PLAN ON SITE.
DEVIATION FROM THE APPROVED EROSION AND SEDIMENTATION CONTROL PLAN WILL BE CONSIDERED A VIOLATION OF
THE FEDERAL NPDES GENERAL PERMIT.
2. PREVENT SPILLING OF FUELS, LUBRICANTS, COOLANTS, HYDRAULIC FLUIDS, AND ANY OTHER PETROLEUM PRODUCTS

AND RODENTICIDE ACT AND IN ACCORDANCE WITH LABEL RESTRICTIONS.
4. CONTROL MANAGEMENT AND DISPOSAL OF LITTER AND SANITARY WASTE FROM THE SITE SO THAT NO ADVERSE IMPACT
TO WATER QUALITY OCCURS,
5. INSPECT ALL EROSION AND SEDIMENTATION CONTROL FACILITIES EVERY SEVEN CALENDAR DAYS (TWICE IN SEVEN
CALENDAR DAYS FOR STORMWATER DISCHARGE TO STREAMS ON THE LATEST EPA -APPROVED 303(d) LIST) AND WITHIN
A 24-HOUR PERIOD OF ANY STORM EVENT OF MORE THAN 0.5 INCHES OF RAIN IN A 24-HOUR PERIOD. MAINTAIN
A RAIN GAUGE ON SITE AND KEEP RECORD OF THE RAINFALL AMOUNTS AND DATES.
6. OBSERVE STORMWATER RUNOFF DISCHARGES AND LOOK FOR CLARITY, FLOATING SOLIDS, SUSPENDED SOLIDS, OIL
SHEEN AND OTHER OBVIOUS INDICATORS OF POLLUTION AND EVALUATE THE EFFECTIVENESS OF THE EROSION AND
SEDIMENTATION CONTROL MEASURES. IF SEDIMENTATION 1S LEAVING THE DISTURBED AREA, TAKE IMMEDIATE ACTION
TO CONTROL THE DISCHARGE.
7. KEEP A RECORD OF THE INSPECTIONS, RECORD ANY VISIBLE SEDIMENTATION FOUND OUTSIDE THE DISTURBED LIMIT
AND RECORD MEASURES TAKEN TO CLEAN UP THE SEDIMENT. MAKE THESE RECORDS AVAILABLE TO THE DIVISIDN
OF WATER QUALITY OR ITS AUTHORIZED AGENT UPON REQUEST.
8. MAINTAIN EROSION AND SEDIMENT CONTROL MEASURES TO KEEP THE OPERATING EFFICIENCY AT OPTIMUM AND
MAINTAINED AT MINIMUM 50% CAPACITY,
9. EARTH BERMS ON SEDIMENT TRAP AND DIVERSIONS TO BE STABILIZED WHEN INSTALLED.
10, GROUND COVER ON ALL SLOPES TO BE ESTABLISHED WITHIN 15 WORKING DAYS OR 30 CALENDAR DAYS, WHICHEVER
IS SHORTER.
