Sedimentation Control Plans and Sediment Basins. A detailed
explanation may be viewed at
http: //portal.ncdenr.org/web/wq/ws/su/construction.
9. Retention Ponds and Bio-retention Cells may be used until
the end of all grading phases and construction of
houses/buildings for collection of sediment. If retention ponds
and bio-retention cells are used for erosion control measures,
then the structure shall be cleaned of collected sediment prior
to certification by engineer.
10. Weather forecast shall be monitored. The contractor shall
prepare for rain events by re-examining all erosion control
measures prior to start of precipitation. Any re -enforcement or
corrections should be performed and documented.
11. If fill materials are to be brought onto this project or waste
materials are to be taken from this project, this information
must be disclosed and shown on the erosion control and grading
plan. Borrow areas and dump sites are considered to be part of
this project and the permittee is responsible for stabilization and
erosion control measures at these sites. These sites have to be
permitted.
12. The erosion control inspector can require, in addition to any
other civil or criminal penalty or injunctive relief, that any
person(s) who is engaged in a land -disturbing activity and fails
to retain sediment generated by the land -disturbing activity, to
restore the waters and land affected by the failure so as to
minimize the detrimental effects of the resulting pollution by
sedimentation.

TEMPORARY SEEDING
DEFINITION
SEEDING DISTURBED AREAS WITH ANNUAL GRASSES OR LEGUMES TO PROVIDE TEMPORARY
GROUND COVER TO LESSEN SOIL EROSION.
PURPOSE
TO TEMPORARILY STABILIZE GRADED CUT AND FILL SLOPES THAT CANNOT BE SEEDED WITH
PERMANENT VEGETATION WITHIN THIRTY DAYS AFTER COMPLETION.
TO TEMPORARILY STABILIZE GRADED AREAS OF BARE SOIL WHERE PERMANENT VEGETATIVE
COVER IS NOT NEEDED OR WHERE GRADING HAS NOT BEEN COMPLETED AND PERMANENT
SEEDING WILL BE DONE LATER.
CONDITIONS WHERE PRACTICE APPLIES
WHERE BARE SOIL HAS BEEN EXPOSED BY GRADING, AND VEGETATIVE COVER IS NEEDED
FOR ONE YEAR OR LESS. MAY INCLUDE SUCH AREAS AS TEMPORARY SEDIMENT POND,
DIVERSIONS, SOIL STOCKPILES, BUILDING PADS, ROUGH -GRADED ROAD BANKS, ETC. IT
IS ALSO USED TO PROVIDE A TEMPORARY PERIMETER BUFFER.
PREPARATION
PREPARE SEEDBED BY RIPPING, CHISELING, HARROWING, TO A DEPTH OF AT
LEAST SIX INCHES SO AS TO PRODUCE A LOOSE, FRIABLE SURFACE. INCORPORATE
750-1,000 POUNDS 10-10-10 FERTILIZER AND UP TO TWO TONS OF DOLOMITIC LIME PER
ACRE (NOTE: LIME MAY NOT BE NEEDED IF A SOIL INDICATED A pH OF 6.5 OR
HIGHER). MULCHING IS REQUIRED ACCORDING TO THE SAME SPECIFICATIONS AS FOR
PERMANENT SEEDING UNLESS WAIVED BY SOIL SCIENTIST. SELECT SEEDING MIXTURE AND

DEFINITION
SEEDING DISTURBED AREAS WITH PERENNIAL GRASSES AND (OR) LEGUMES TO PROVIDE A
PERMANENT VEGETATIVE COVER TO LESSEN RUNOFF AND SOIL EROSION.
PURPOSE
TO LESSEN SOIL EROSION AND PERMANENTLY STABILIZE DISTURBED AREAS CREATED BY
GRADING OF CONSTRUCTION SITES.
CONDITIONS WHERE PRACTICE APPLIES
ALL BARE SOIL AREAS ON CONSTRUCTION SITES WHICH ARE NOT COVERED BY STRUCTURES
OR OTHER EROSION CONTROL DEVICES.
PREPARATION
PREPARE SEEDBED BY SPREADING 3 - 6 INCHES OF TOPSOIL OVER AREA TO BE SEEDED.
REMOVE ALL STONES, BOULDERS, STUMPS OR DEBRIS FROM THE SURFACE WHICH WOULD
PROHIBIT GERMINATION OR PLANT GROWTH.
INCORPORATE INTO THE SOIL 800 TO 1,000 POUNDS OF 10-10-10 FERTILIZER PLUS 500
POUNDS OF TWENTY PERCENT (207) SUPERPHOSPHATE PER ACRE AND TWO TONS OF
DOLOMITIC LIME PER ACRE UNLESS SOIL TESTS INDICATE THAT A LOWER RATE OF LIME
CAN BE USED.

INLET ZONE
1. CLEAR, GRUB AND STRIP THE AREA UNDER THE EMBANKMENT OF ALL VEGETATION AND ROOT MAT. REMOVE ALL SURFACE SOIL CONTAINING HIGH AMOUNTS
OF ORGANIC MATTER AND STOCKPILE OR DIPOSE OF IT PROPERLY. HAUL ALL OBJECTIONABLE MATERIAL TO THE DESIGNATED DISPOSAL AREA. PLACE
FIRST CHAMBER TEMPORARY SEDIMENT CONTROL MEASURES BELOW BASIN AS NEEDED.
2. ENSURE THAT FILL MATERIAL FOR THE EMBANKMENT IS FREE OF ROOTS, WOODY VEGETATION, ORGANIC MATTER, AND OTHER OBJECTIONABLE MATERIAL. PLACE
SEDIMENT PIT THE FILL IN LIFTS NOT TO EXCEED 9", AND MACHINE COMPACT IT, OVER FILL THE EMBANKMENT 6" TO ALLOW FOR SETTLEMENT.
3. SHAPE THE BASIN TO THE SPECIFIED DIMENSIONS. PREVENT THE SKIMMING DEVICE FROM SETTLING INTO THE MUD BY EXCAVATING A SHALLOW PIT UNDER
THE SKIMMER OR PROVIDING A LOW SUPPORT UNDER THE SKIMMER OF STONE OR TIMBER.
4. PLACE THE BARREL (TYPICALLY 4-INCH SCHEDULE 40 PVC PIPE) ON A FIRM, SMOOTH FOUNDATION OF IMPERVIOUS SOIL. DO NOT USE PERVIOUS MATERIAL
SECOND CHAMBER SUCH AS SAND, GRAVEL OR CRUSHED STONE AS BACKFILL AROUND THE PIPE. PLACE THE FILL MATERIAL AROUND THE PIPE SPILLWAY IN 4-INCH LAYERS
AND COMPACT IT UNDER AND AROUND THE PIPE TO AT LEAST THE SAME DENSITY AS THE
FENCE AND FABRIC
BURIED IN TRENCH-
6"x6" TRENCH,-
BACKFILLED AND
COMPACTED
ADJACENT EMBANKMENT. CARE MUST BE TAKEN NOT TO RAISE THE
PIPE FROM THE FIRM CONTACT WITH ITS FOUNDATION WHEN COMPACTING UNDER THE PIPE HAUNCHES.
PLACE A MINIMUM DEPTH OF 2 FEET OF COMPACTED BACKFILL OVER THE PIPE SPILLWAY BEFORE CROSSING IT WITH CONSTRUCTION EQUIPMENT. IN NO CASE
SHOULD THE PIPE CONDUIT BE INSTALLED BY CUTTING A TRENCH THROUGH THE DAM AFTER THE EMBANKMENT IS COMPLETE.
5. ASSEMBLE THE SKIMMER FOLLOWING THE MANUFACTURERS INSTRUCTIONS, OR AS DESIGNED.
6. LAY THE ASSEMBLED SKIMMER ON THE BOTTOM OF THE BASIN WITH THE FLEXIBLE JOING AT THE INLET OF THE BARREL PIPE. ATTACH THE FLEXIBLE JOINT
TO THE BARREL PIPE AND POSITION THE SKIMMER OVER THE EXCAVATED PIT OR SUPPORT. BE SURE TO ATTACH A ROPE TO THE SKIMMER AND ANCHOR IT
TO THE SIDE OF THE BASIN. THIS WILL BE USED TO PULL THE SKIMMER TO THE SIDE FO MAINTENANCE.
7. EARTHEN SPILLWAYS- INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATES EXTENT POSSIBLE. THE ACHIEVEMENT OF PLANNED ELEVATIONS, GRADE,
DESIGN WIDTH AND ENTRANCE AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCESSFULL OPERATION OF THE SPILLWAY. THE SPILLWAY SHOULD BE LINED
WITH LAMINATED PLASTIC OR IMPERMEABLE GEOTEXTILE FABRIC. THE GABRIC MUST BE WIDE AND LONG ENOUGH TO COVER THE BOTTOM AND SIDES AND
EXTEND ONTO THE TOP OF THE DAM FOR ANCHORING IN A TRENCH. THE EDGES MAY BE SECURED WITH 8-INCH STAPLES OR PINS. THE FABRIC MUST BE
LONG ENOUGH TO EXTEND DOWN THE SLOPE AND EXIT ONTO STABLE GROUND.D THE WIDTH OF THE FABRIC MUST BE ONE PIECE, NOT JOINED OR SPLICED;
OTHERWISE WATER CAN ET UNDER THE FABRIC. IF THE LENGTH OF THE FABRIC IS INSUFFICIENT FOR THE ENTIRE LENGTH OF THE SPILLWAY, MULTIPLE
SECTIONS, SPANNING THE COMPLETE WIDTH, MAY BE USED. THE UPER SECTION(S) SHOULD OVERLAP THE LOWER SECTION(S) SO THAT WATER CANNOT FLOW
UNDER THE FABRIC. SECURE THE UPPER EDGE AND SIDES OF THE FABRIC IN A TRENCH WITH STAPLES OR PINS.
B. INLETS- DISCHARGE WATER INTO THE BASIN IN A MANNER TO PREVENT EROSION. USE TEMPORARY SLOPE DRAINS OR DIVERSIONS WITH OUTLET PROTECTION
TO DIVERT SEDIMENT -LADEN WATER TO THE UPPER END OF THE POOL AREA TO IMPROVE BASIN TRAP EFFICIENTY.
9. EROSION CONTROL- CONSTRUCT THE STRUCTURE SO THAT THE DISTURBED AREA IS MINIMIZED. DIVERT SURFACE WATER AWAY FROM BARE AREAS. COMPLETE
THE EMBANKMENT BEFORE THE AREA IS CLEARED. STABILIZE THE EMERGENCY SPILLWAY EMBANKMENT AND ALL OTHER DISTURBED ARAS ABOVE THE CREST
OF THE PRINCIPAL SPILLWAY IMMEDIATELY AFTER CONSTRUCTION.
10. INSTALL POROUS BAFFLES.
11. AFTER ALL THE SEDIMENT -PRODUCING AREAS HAVE BEEN PERMANENTLY STABILIZED, REMOVE THE STRUCTURE AND ALL THE UNSTABLE SEDIMENT. SMOOTH
THE AREA TO BLEND WITH THE ADJOINING AREAS AND STABILIZE PROPERLY.
MAINTENANCE
INSPECT, SKIMMER SEDIMENT BASINS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (1/2 INCH OR GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY.
REMOVE SEDIMENT AND RESTORE THE BASIN TO ITS ORIFINAL DIMENSIONS WHEN SEDIMENT ACCUMULATES TO 1/2 THE HEIGHT OF THE FIRST BAFFLE. PULL THE
SKIMMER TO ONE SIDE SO THAT THE SEDIMENT UNDERNEATH IT CAN BE EXCAVATED. ESCAVATE 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.
REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE -ANCHOR THE BAFFLES IF WATTER IS FLOWING UNDERNEATH OR AROUND THEM
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 AND RESTORE 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.
IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND THE OBSTRUCTION CLEARED WITHA PLUMBER'S SNAKE OR BY
FLUSHING WITH WATER. BE SURE AND REPLACE THE ORIFICE BEFORE REPOSITIONING THE SKIMMER.
CHECK THE FABRIC LINED SPILLWAY FOR DAMAGE AND MAKE ANY REQUIRED REPAIRS WITH FABRIC THAT SPANS THE FULL WIDTH OF THE SPILLWAY. 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 SKIMMER AND POOL AREAS.
FREEZING WEATHER CAN RESULT IN ICE FORMING IN THE BASIN. SOME SPECIAL PRECAUTIONS SHOULD BE TAKEN IN THE WINTER TO PREVENT THE SKIMMER
FROM PLUGGING WITH ICE.
