EROSION AND SEDIMENT CONTROL SEQUENCE:
PHASE 3:
1.INSTALL SUBSTATION AND SHOULDER YARD BLANKET (BY
OTHERS).
2.REMOVE TEMPORARY LAYDOWN AND PARKING AREA STONE.
AREA TO BE PERMANENT SEEDED AND STABILIZED TO FINAL
GRADES.
3.ONCE CONTRIBUTING DRAINAGE AREA TO A TEMPORARY
SEDIMENT BASIN IS STABILIZED AS APPROVED BY ENGINEER OF
RECORD AND NCDEQ-DEMLR INSPECTOR, CONTRACTOR MAY
REMOVE TEMPORARY SEDIMENT BASIN. THIS MAY OCCUR AT
DIFFERENT TIMES DURING THIS PHASE FOR EACH OF THE THREE
PROPOSED TEMPORARY SEDIMENT BASINS. PERIMETER E&SC
CONTROLS (SILT FENCE) DOWN GRADIENT FROM THE SEDIMENT
BASIN SHALL REMAIN IN PLACE UNTIL SEDIMENT BASIN REMOVAL
IS COMPLETE, FINAL GRADED, AND PERMANENT SEED IS
ESTABLISHED AND STABILIZED.
4.REMOVE TEMPORARY CONSTRUCTION ENTRANCE STONE AND
INSTALL PERMANENT DRIVEWAY SECTION TO FINAL GRADES.
5.STABILIZATION SHALL BE ESTABLISHED ON ALL DISTURBED AREAS
WITHIN 7 OR 14 DAYS OF COMPLETION OF ANY PHASE OF GRADING
ACTIVITIES OR WHERE CONSTRUCTION WILL TEMPORARILY CEASE
FOR MORE THAN 7-14 CALENDAR DAYS. SEE THE STABILIZATION
TIME FRAME ON DETAIL SHEET.
6.AFTER SITE IS PERMANENTLY STABILIZED, CONTACT THE DEMLR
E&SC INSPECTOR PRIOR TO REMOVAL OR MODIFICATION OF E&SC
DEVICES.
7.REMOVE ALL TEMPORARY E&SC MEASURES AND PROVIDE
PERMANENT SEEDING WHERE TEMPORARY MEASURES HAVE
BEEN REMOVED AND GROUND COVER IS NOT ADEQUATE.
8.CONTACT DEMLR FOR A CLOSE OUT INSPECTION ONCE ALL E&SC
MEASURES HAVE BEEN REMOVED AND THE SITE HAS BEEN
PERMANENTLY STABILIZED. CONTRACTOR DEMOBILIZES FROM
SITE.
9.WHEN THE PROJECT IS COMPLETE, THE PERMITTEES SHALL
CONTACT DEMLR TO CLOSE OUT THE E&SC PLAN. AFTER THE
DEMLR INFORMS THE PERMITTEE OF THE PROJECT CLOSE OUT,
VIA INSPECTION REPORT, THE PERMITTEE SHALL VISIT
DEQ.NC.GOV/NCG01 TO SUBMIT AND E-NOT. A $120 ANNUAL
GENERAL PERMIT FEE WILL BE CHARGED UNTIL THE E-NOT HAS
BEEN FILLED OUT.

GRADE.

CONSTRUCTION SPECIFICATIONS:
1.ENSURE THAT THE SUBGRADE FOR THE FILTER AND RIP-RAP FOLLOWS THE REQUIRED LINES AND
GRADES SHOWN IN THE PLAN. COMPACT ANY FILL REQUIRED IN THE SUBGRADE TO THE DENSITY
OF THE SURROUNDING UNDISTURBED MATERIAL. LOW AREAS IN THE SUBGRADE ON UNDISTURBED
SOIL MAY ALSO BE FILLED BY INCREASING THE RIP-RAP THICKNESS.
2.THE RIP-RAP AND GRAVEL FILTER MUST CONFORM TO THE SPECIFIED GRADING LIMITS SHOWN ON
THE PLANS.
3.FILTER CLOTH, WHEN USED, MUST MEET DESIGN REQUIREMENTS AND BE PROPERLY PROTECTED
FROM PUNCHING OR TEARING DURING INSTALLATION. REPAIR ANY DAMAGE BY REMOVING THE
RIP-RAP AND PLACING ANOTHER PIECE OF FILTER CLOTH OVER THE DAMAGED AREA. ALL
CONNECTING JOINTS SHOULD OVERLAP SO THE TOP LAYER IS ABOVE THE DOWNSTREAM LAYER A
MINIMUM OF 1 FOOT. IF THE DAMAGE IS EXTENSIVE, REPLACE THE ENTIRE FILTER CLOTH.
4.RIP-RAP MAY BE PLACED BY EQUIPMENT, BUT TAKE CARE TO AVOID DAMAGING THE FILTER CLOTH.
5.THE MINIMUM THICKNESS OF THE RIP-RAP SHOULD BE 1.5 TIMES THE MAXIMUM STONE DIAMETER.
6.RIP-RAP MAY BE FIELD STONE OR ROUGH QUARRY STONE. IT SHOULD BE HARD, ANGULAR, HIGHLY
WEATHER-RESISTANT AND WELL GRADED.
7.CONSTRUCT THE APRON ON ZERO GRADE WITH NO OVERFILL AT THE END. MAKE THE TOP OF THE
RIP-RAP AT THE DOWNSTREAM END LEVEL WITH THE RECEIVING AREA OR SLIGHTLY BELOW IT.
8.ENSURE THAT THE APRON IS PROPERLY ALIGNED WITH THE RECEIVING STREAM AND PREFERABLY
STRAIGHT THROUGHOUT ITS LENGTH. IF A CURVE IS NEEDED TO FIT SITE CONDITIONS, PLACE IT IN
THE UPPER SECTION OF THE APRON.
9.IMMEDIATELY AFTER CONSTRUCTION, STABILIZE ALL DISTURBED AREAS WITH VEGETATION.
INSTALLATION AND MAINTENANCE NOTES:
1.INSPECT RIP-RAP OUTLET STRUCTURES WEEKLY AND AFTER SIGNIFICANT (1 INCH OR GREATER)
RAINFALL EVENTS TO SEE IF ANY EROSION AROUND OR BELOW THE RIP-RAP HAS TAKEN PLACE,
OR IF STONES HAVE BEEN DISLODGED. IMMEDIATELY MAKE ALL NEEDED REPAIRS TO PREVENT
FURTHER DAMAGE.

GENERAL NOTES:
1.SEDIMENT BASINS MUST BE CLEANED OUT TO RESTORE ORIGINAL CAPACITY ONCE THE SEDIMENT ACCUMULATION WITHIN THE BASIN REACHES ONE-THIRD OF THE ORIGINAL DESIGN DEPTH.
2.INTERIOR SLOPES, EXTERIOR SLOPES, AND BERM CREST OF SEDIMENT BASINS SHALL BE STABILIZED WITH EROSION CONTROL MATTING (EXCELSIOR OR EQUAL AT A MINIMUM).
3.ALL SEDIMENT BASINS SHALL INCLUDE POROUS BAFFLES PER THE DRAWINGS AND INSTALLED PER NCDENR REQUIREMENTS.
4.SKIMMER SIZE REFERS TO THE MAXIMUM DIAMETER OF THE INLET. FOR EXAMPLE A 8"SKIMMER HAS A 8" MAXIMUM ORIFICE SIZE.
5.BAFFLE MATERIAL SHALL BE MATERIALS SUCH AS 700 G/M COIR EROSION BLANKET, COIR MESH, OR TREE PROTECTION FENCE FOLDED OVER TO REDUCE PORE SIZE.
6.THE BAFFLE MATERIAL NEEDS TO BE SECURED AT THE BOTTOM AND SIDES USING STAPLES OR BY TRENCHING AS FOR SILT FENCE.
MAINTENANCE:
1.INSPECT TEMPORARY SEDIMENT BASINS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (1
2 INCH OR GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE SEDIMENT AND RESTORE BASIN TO ITS
ORIGINAL DIMENSIONS WHEN IT ACCUMULATES TO ONE-HALF THE DESIGN DEPTH. PLACE REMOVED SEDIMENT IN AN AREA WITH SEDIMENT CONTROLS. PULL THE SKIMMER TO ONE SIDE SO THAT THE SEDIMENT
UNDERNEATH IT CAN BE EXCAVATED. EXCAVATE THE SEDIMENT FROM THE ENTIRE BASIN, NOT JUST AROUND THE SKIMMER OR THE FIRST CELL. MAKE SURE VEGETATION GROWING IN THE BOTTOM OF THE BASIN
DOES NOT HOLD DOWN THE SKIMMER.
2.CHECK THE EMBANKMENT, SPILLWAYS, AND OUTLET FOR EROSION DAMAGE, AND INSPECT THE EMBANKMENT FOR PIPING AND SETTLEMENT. MAKE ALL NECESSARY REPAIRS IMMEDIATELY. REMOVE ALL TRASH
AND OTHER DEBRIS FROM THE RISER AND POOL AREA.
3.REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE-ANCHOR THE BAFFLES IF WATER IS FLOWING UNDERNEATH OR AROUND THEM.
4.IF THE SKIMMER IS CLOGGED WITH TRASH AND THERE IS WATER IN THE BASIN, USUALLY JERKING ON THE ROPE WILL MAKE THE SKIMMER BOB UP AND DOWN AND DISLODGE THE DEBRIS TO RESTORE THE FLOW.
IF THIS DOES NOT WORK, PULL THE SKIMMER OVER TO THE SIDE OF THE BASIN AND REMOVE THE DEBRIS. ALSO CHECK THE ORIFICE INSIDE THE SKIMMER TO SEE IF IT IS CLOGGED; IF SO, REMOVE THE DEBRIS.
5.IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND THE OBSTRUCTION CLEARED WITH A PLUMBER'S SNAKE OR BY FLUSHING WITH WATER. BE SURE AND REPLACE THE
ORIFICE BEFORE REPOSITIONING THE SKIMMER.
