SPECIFICATIONS.
2.A COPY OF THE APPROVED EROSION CONTROL PLAN MUST BE ON FILE AT THE JOB
SITE AT ALL TIMES.
3.FAILURE TO FOLLOW THE APPROVED PLAN SEQUENCE AND DETAILS COULD
SUBJECT THE CONTRACTOR TO FINES AND PENALTIES ISSUED BY THE DWQ.
4.FIELD VERIFY ALL DIMENSIONS AND GRADES ON THESE PLANS PRIOR TO
CONSTRUCTION. FAILURE TO NOTIFY THE OWNER OF ANY DISCREPANCIES PRIOR
TO PROCEEDING WITH PLAN OR GRADE CHANGES, MAY RESULT IN NO EXTRA
COMPENSATION PAID TO THE CONTRACTOR FOR ANY WORK DONE DUE TO
DIMENSIONS OR GRADES SHOWN INCORRECTLY.
5.EXCAVATION AND EARTH MOVING OPERATIONS SHALL BE CONDUCTED UNDER THE
SUPERVISION OF THE GEOTECHNICAL ENGINEER.
6.VERIFY THE LOCATION OF ALL EXISTING UTILITIES PRIOR TO CONSTRUCTION.
EXISTING UTILITIES SHOWN ARE FROM THE BEST AVAILABLE RECORDS AND FROM A

SEDIMENTATION PERMIT NUMBER OR MINE PERMIT NUMBER WILL BE DISCLOSED.
PHASE I EROSION CONTROL CONSTRUCTION SEQUENCE:
1.A LAND DISTURBANCE PRECONSTRUCTION MEETING IS REQUIRED PRIOR TO ANY
DISTURBANCE ON SITE. INVITE THE LOCAL NCDENR INSPECTOR, OWNER, OWNERS
ENGINEER, ARCHITECT, AND GRADING CONTRACTOR. SCHEDULE THE MEETING AT
LEAST 48 HOURS PRIOR TO THE PRE-CONSTRUCTION MEETING AND LAND
DISTURBANCE. NOTIFY LOCAL NCDENR REGIONAL OFFICE PRIOR TO ANY LAND
DISTURBANCE.
2.INSTALL CONSTRUCTION ENTRANCE, BEGIN TREE CLEARING, AND PREPARE SITE
FOR SOIL SURCHARGING AS INDICATED ON PLAN.
3.INSTALL TEMPORARY DIVERSION DITCHES "A", AND "B", AND THE SEDIMENT TRAP,
CLEARING ONLY NECESSARY AREAS. CONSTRUCT THE SEDIMENT TRAP BY
EXCAVATING THE AREA TO THE GRADES SHOWN AND CONSTRUCTING THE
EMBANKMENT TO THE REQUIRED DENSITY. INSTALL THE SKIMMER DEVICE.
STABILIZE ALL DISTURBED SOILS UPON COMPLETION OF THE SEDIMENT TRAP.
4.ENSURE PHASE 1 MEASURES HAVE BEEN COMPLETED, INSPECTED, AND
APPROVED. ADJUST AS NEEDED DURING OBSERVATION PERIOD FOR THE SOIL
SURCHARGING.
SILT FENCE OUTLETS ARE TO BE PROVIDED ALONG ALL LOW
POINTS OF SILT FENCE AND AREAS WHERE RUNOFF MAY

GENERAL EROSION AND SEDIMENT CONTROL NOTES:
1.ALL CONSTRUCTION SHALL COMPLY WITH NCDENR STANDARDS AND SPECIFICATIONS.
2.A COPY OF THE APPROVED EROSION CONTROL PLAN MUST BE ON FILE AT THE JOB SITE
AT ALL TIMES.
3.FAILURE TO FOLLOW THE APPROVED PLAN SEQUENCE AND DETAILS COULD SUBJECT
THE CONTRACTOR TO FINES AND PENALTIES ISSUED BY THE DWQ.
4.FIELD VERIFY ALL DIMENSIONS AND GRADES ON THESE PLANS PRIOR TO
CONSTRUCTION. FAILURE TO NOTIFY THE OWNER OF ANY DISCREPANCIES PRIOR TO
PROCEEDING WITH PLAN OR GRADE CHANGES, MAY RESULT IN NO EXTRA
COMPENSATION PAID TO THE CONTRACTOR FOR ANY WORK DONE DUE TO DIMENSIONS
OR GRADES SHOWN INCORRECTLY.
5.EXCAVATION AND EARTH MOVING OPERATIONS SHALL BE CONDUCTED UNDER THE
SUPERVISION OF THE GEOTECHNICAL ENGINEER.
6.VERIFY THE LOCATION OF ALL EXISTING UTILITIES PRIOR TO CONSTRUCTION. EXISTING
UTILITIES SHOWN ARE FROM THE BEST AVAILABLE RECORDS AND FROM A SURVEY OF
ABOVE GROUND FEATURES. NO WARRANTY IS GIVEN OR IMPLIED AS TO THE ACCURACY
OF THE INFORMATION. ALL EXISTING UTILITIES SHOULD BE CONSIDERED APPROXIMATE
IN LOCATION AND VERIFIED PRIOR TO COMMENCING ACTIVITY ON SITE.
7.ALL ADJACENT ROADS TO THE SITE ARE TO BE SWEPT AND WASHED AT THE END OF
EACH WORK DAY TO ENSURE NO SEDIMENT COLLECTS ON THE ROADWAYS.
8.INSPECT AND PROPERLY MAINTAIN ALL EROSION AND SEDIMENT CONTROL MEASURES
WEEKLY AND AFTER EVERY RAINFALL EVENT.
9.INSTALL ANY ADDITIONAL EROSION CONTROL MEASURES AS NECESSARY TO PREVENT
SEDIMENT RUNOFF.
10.PROVIDE NCDENR-DWQ WITH THE LOCATION OF OFFSITE STOCKPILES USED TO STORE
EXCAVATED SOIL FROM THE SITE. THE LOCATION OF OFFSITE STOCKPILES MUST BE AN
UPLAND AREA. IF AN OFFSITE BORROW OR SPOIL SITE IS UTILIZED, THEN THE
DISTURBED AREA FOR THE BORROW/SPOIL SITE MUST BE INCLUDED IN THE LAND
DISTURBANCE PERMIT. THE CONTRACTOR WILL PROVIDE THE LOCATION OF ALL
EXCAVATED SOILS USED FOR THIS PROJECT TO NCDENR-DWQ. THIS AREA MUST ALSO
BE AN UPLAND AREA.
NPDES GROUND STABILIZATION:
SOIL STABILIZATION SHALL BE ACHIEVED ON ANY AREA OF A SITE WHERE
LAND-DISTURBING ACTIVITIES HAVE TEMPORARILY OR PERMANENTLY CEASED
ACCORDING TO THE FOLLOWING SCHEDULE:
1.ALL PERIMETER DIKES, SWALES, DITCHES, PERIMETER SLOPES AND ALL SLOPES
STEEPER THAN 3 HORIZONTAL TO 1 VERTICAL (3:1) SHALL BE PROVIDED TEMPORARY
OR PERMANENT STABILIZATION WITH GROUND COVER AS SOON AS PRACTICABLE BUT
IN ANY EVENT WITHIN 7 CALENDAR DAYS FROM THE LAST LAND-DISTURBING
ACTIVITY.
2.ALL OTHER DISTURBED AREAS SHALL BE PROVIDED TEMPORARY OR PERMANENT
STABILIZATION WITH GROUND COVER AS SOON AS PRACTICABLE BUT IN ANY EVENT
WITHIN 14 CALENDAR DAYS FROM THE LAST LAND-DISTURBING ACTIVITY.
NOTE:
THE NPDES CONSTRUCTION PERMIT REQUIRES EROSION CONTROL DEVICES AND STORM
WATER OUTFALLS BE INSPECTED WEEKLY (EVERY 7 CALENDAR DAYS) AND WITHIN 24 HRS
OF A .5 INCH RAIN EVENT. IT WILL BE THE RESPONSIBILITY OF THE CONTRACTOR TO
CONDUCT THESE INSPECTIONS AND MAINTAIN RECORDS UNTIL THE AREA HAS
STABILIZED, EVIDENT BY 95% VEGETATIVE GROWTH FOR AREAS PROVIDED SEEDING. TO
FACILITATE RAINFALL MONITORING A RAIN GAUGE IS REQUIRED TO BE ON SITE.
ADDITIONALLY THE CONTRACTOR IS RESPONSIBLE FOR CONDUCTING “SELF
INSPECTIONS” INDICATING THE DATE BMPS ARE INSTALLED AND STABILIZATION
MEASURES (SEEDING/MULCHING OR SOD) ARE INITIATED. THE “SELF INSPECTION”
REPORTS WILL BE MAINTAINED ALONG WITH THE “NPDES” INSPECTION REPORTS. ONCE
STABILIZATION HAS BEEN ACCOMPLISHED INSPECTION RECORDS ARE TO BE FORWARDED
TO EAD AND ALL TEMPORARY EROSION/SEDIMENTATION CONTROL DEVICES REMOVED.
THE CONTRACTOR IS RESPONSIBLE FOR MAINTAINING COMPLIANCE WITH ALL PERMITS
AND PLANS, ANY CHANGES WILL BE APPROVED BY THE STATE PRIOR TO EXECUTION. A
COPY OF THE EROSION AND SEDIMENTATION CONTROL PLAN, LETTER OF APPROVAL, AND
NPDES CONSTRUCTION PERMIT WILL BE MAINTAINED BY THE CONTRACTOR AT THE
ONSITE OFFICE. IF SOIL IS REMOVED FROM OR BROUGHT ONSITE, THE APPLICABLE SOLID
WASTE MANAGEMENT PERMIT NUMBER, EROSION SEDIMENTATION PERMIT NUMBER OR
MINE PERMIT NUMBER WILL BE DISCLOSED.

DAM EMBANKMENT AND SOIL COMPACTION SPECIFICATIONS
1.CONTROLLED FILL, AS SPECIFIED BY THE GEOTECHNICAL ENGINEER, IN THE DAM EMBANKMENT
/KEY TRENCH SHALL BE PLACED IN 6-INCH LOOSE LAYERS (3-INCH LOOSE LAYERS WITHIN 3-FEET OF
EITHER SIDE OF THE PRINCIPAL SPILLWAY PIPE TO A DEPTH OF 2-FEET OVER THE PIPE) AND SHALL
BE COMPACTED TO A DENSITY OF NO LESS THAN 95% OF THE STANDARD PROCTOR MAXIMUM
DENSITY AT A MOISTURE CONTENT OF + OR - TWO PERCENTAGE POINTS OF THE OPTIMUM
MOISTURE CONTENT IN ACCORDANCE WITH ASTM D698.
2.ALL VISIBLE ORGANIC DEBRIS SUCH AS ROOTS AND LIMBS SHALL BE REMOVED FROM THE FILL
MATERIAL PRIOR TO COMPACTION TO THE REQUIRED DENSITY. SOILS WITH ORGANIC MATTER
CONTENT EXCEEDING 5% BY WEIGHT SHALL NOT BE USED. STONES GREATER THAN 3-INCH (IN ANY
DIRECTION) SHALL BE REMOVED FROM THE FILL PRIOR TO COMPACTION.
3.FILL MATERIAL PLACED AT DENSITIES LOWER THAN SPECIFIED MINIMUM DENSITIES OR AT
MOISTURE CONTENTS OUTSIDE THE SPECIFIED RANGES OR OTHERWISE NOT CONFORMING TO
SPECIFIED REQUIREMENTS SHALL BE REMOVED AND REPLACED WITH ACCEPTABLE MATERIALS.
4.ANY FILL LAYER THAT IS SMOOTH DRUM ROLLED TO REDUCE MOISTURE PENETRATION DURING A
STORM EVENT SHALL BE PROPERLY SCARIFIED PRIOR TO THE PLACEMENT OF THE NEXT SOIL LIFT.
5.SURFACE WATER AND STREAM FLOW SHALL BE CONTINUOUSLY CONTROLLED THROUGHOUT
CONSTRUCTION AND THE PLACEMENT OF CONTROLLED FILL.
6.FOUNDATION AREAS MAY REQUIRE UNDERCUTTING OF COMPRESSIBLE AND/OR UNSUITABLE SOILS
IN ADDITION TO THAT INDICATED ON THE PLANS. ALL SUCH UNDERCUTTING SHALL BE PERFORMED
AT THE DISCRETION OF THE GEOTECHNICAL ENGINEER AND SHALL BE MONITORED AND
DOCUMENTED. IN NO CASE SHALL THERE BE AN ATTEMPT TO STABILIZE ANY PORTIONS OF THE
FOUNDATION SOILS WITH CRUSHED STONE.
7.TREATMENT OF SEEPAGE AREAS, SUBGRADE PREPARATION, FOUNDATION DEWATERING AND ROCK
FOUNDATION PREPARATION (I.E., TREATMENT WITH SLUSH GROUTING, DENTAL CONCRETE, ETC.)
MAY BE REQUIRED AT THE DISCRETION OF THE GEOTECHNICAL ENGINEER. ALL SUCH ACTIVITIES
SHALL BE CLOSELY MONITORED AND DOCUMENTED BY THE GEOTECHNICAL ENGINEER.
8.FILL ADJACENT TO THE RISER AND PRINCIPAL SPILLWAY PIPE SHALL BE PLACED SO THAT LIFTS ARE
AT THE SAME LEVEL ON BOTH SIDES OF THE STRUCTURES.
9.EARTHWORK COMPACTION WITHIN 3-FEET OF ANY STRUCTURES SHALL BE ACCOMPLISHED BY
MEANS OF HAND TAMPERS, MANUALLY DIRECTED POWER TAMPERS OR PLATE COMPACTORS OR
MINIATURE SELF-PROPELLED ROLLERS.
10.COMPACTION BY MEANS OF DROP WEIGHTS FROM A CRANE OR HOIST SHALL NOT BE PERMITTED.
11.HEAVY EQUIPMENT SHALL NOT BE ALLOWED TO PASS OVER CAST-IN-PLACE STRUCTURES
(INCLUDING THE CRADLE) UNTIL ADEQUATE CURING TIME HAS ELAPSED.
12.INSTALL CLAY LINER PER MANUFACTURER'S INSTALLATION INSTRUCTIONS
13.TO RE-ESTABLISH VEGETATION AFTER CONSTRUCTION, A 2 TO 3-INCH LAYER OF TOPSOIL SHALL BE
PLACED ON THE DISTURBED EMBANKMENT SURFACE AND THE AREA SEEDED AND MULCHED OR
HYDROSEEDED WITH NON-CLUMPING TURF GRASS
14.NO TREES OR WOODY VEGETATION ARE ALLOWED TO BE PLANTED ON THE DAM OR EMBANKMENT.
TESTING, OBSERVATION, AND CERTIFICATION
1.TESTS OF THE DEGREE (%) OF COMPACTION OF THE PLACED FILL IN THE DAM /KEY TRENCH SHALL
BE PERFORMED AS A PART OF THE PERMITTEE'S NORMAL QUALITY CONTROL PROGRAM FOR THE
CONSTRUCTION OF THE DAM. TESTS SHALL BE CONDUCTED CONCURRENT WITH THE INSTALLATION
OF THE COMPACTED FILL AND THE CONTRACTOR SHALL COORDINATE THE CONSTRUCTION OF THE
DAM SO THAT THE TESTING CAN BE COMPLETED. SHOULD THE RESULTS OF THE TESTS INDICATE
THAT THE SPECIFIED DEGREE OF COMPACTION HAS NOT BEEN OBTAINED; THE PORTIONS OF THE
DAM REPRESENTED BY SUCH TESTS SHALL BE REWORKED OR REBUILT. ALL PORTIONS OF THE DAM
SHALL ACHIEVE THE SPECIFIED MINIMUM DEGREE OF COMPACTION.
2.CONSTRUCTION OF CLASS A, B AND C DAM EMBANKMENTS SHALL BE DONE UNDER THE
OBSERVATION OF A QUALIFIED GEOTECHNICAL ENGINEER, WHO IS REGISTERED AS A
PROFESSIONAL ENGINEER IN THE STATE OF NORTH CAROLINA. THE GEOTECHNICAL ENGINEER
MUST HAVE EXPERIENCE IN THE DESIGN AND CONSTRUCTION MONITORING OF DAMS OF THE SIZE
AND SCOPE COVERED BY THESE STANDARDS AND GUIDELINES.
3.ON CLASS A, B, AND C DAMS (WITH THE EXCEPTION OF DETENTION ONLY CLASS C DAMS THAT
COLLECT DRAINAGE FROM AN AREA OF 25-ACRES OR LESS), THE GEOTECHNICAL ENGINEER, AS
DEFINED ABOVE, SHALL OBSERVE ALL ASPECTS OF THE CONSTRUCTION OF THE DAM (I.E.,
PREPARATION OF THE FOUNDATION, INSTALLATION OF THE CUT-OFF TRENCH, INSTALLATION OF
THE PRINCIPAL SPILLWAY PIPE, INSTALLATION OF THE INTERNAL DRAINAGE, INSTALLATION OF
COMPACTED FILL, ETC.). THE FREQUENCY OF OBSERVATION AND TESTING MUST BE SUFFICIENT
FOR THE GEOTECHNICAL ENGINEER (OR THE DESIGN ENGINEER ON CLASS D DAMS AND CLASS C,
DETENTION ONLY, DAMS) TO STATE, IN HIS/HER PROFESSIONAL OPINION, THAT THE SPECIFIC ITEMS
OBSERVED AND TESTED WERE INSTALLED IN ACCORDANCE WITH THE APPROVED CONSTRUCTION
DRAWINGS AND SPECIFICATIONS.
GENERAL NOTES:
1.ALL CONSTRUCTION SHALL BE IN ACCORDANCE WITH THE NEW HANOVER COUNTY, NCDEQ AND
NCDOT STANDARDS, SPECIFICATIONS AND DETAILS.
2.SEE GRADING PLAN FOR MORE INFORMATION ON ENTIRE SITE GRADING.
DRY POND CONSTRUCTION NOTES:
1.SIDE SLOPES STABILIZED WITH VEGETATION SHALL BE NO STEEPER THAN
3:1.
2.THE POND SHALL BE STABILIZED WITHIN 14 DAYS OF CONSTRUCTION.
3.THE GRADES SHOWN ON THIS PLAN ARE FINISHED GRADES AND INCLUDE AT
LEAST FOUR INCHES OF TOPSOIL IS REQUIRED FOR BOTH LINED AND
UNLINED PONDS. A SOIL ANALYSIS SHOULD BE CONDUCTED WITHIN THE
STORMWATER FACILITY AREA TO ASSURE HEALTHY VEGETATION GROWTH
AND TO PROVIDE ADEQUATE INFILTRATION RATES.
4.PRIOR TO CERTIFICATION, A DENSE STAND OF NON-CLUMPING TURF GRASS
MUST BE IN PLACE ON ALL SLOPES, DAM, AND SPILLWAY. CONTRACTOR TO

TEMPORARY SEEDING SPECIFICATIONS
COMPLETE GRADING BEFORE PREPARING SEEDBEDS, AND INSTALL ALL NECESSARY EROSION CONTROL PRACTICES SUCH AS, DIKES, WATERWAYS, AND
BASINS. MINIMIZE STEEP SLOPES BECAUSE THEY MAKE SEEDBED PREPARATION DIFFICULT AND INCREASE THE EROSION HAZARD. IF SOILS BECOME
COMPACTED DURING GRADING, LOOSEN THEM TO A DEPTH OF 6-8 INCHES USING A RIPPER, HARROW, OR CHISEL PLOW.
SEEDBED PREPARATIONS
GOOD SEEDBED PREPARATION IS ESSENTIAL TO SUCCESSFUL PLANT ESTABLISHMENT. A GOOD SEEDBED IS WELL-PULVERIZED, LOOSE, AND UNIFORM.
WHERE HYDROSEEDING METHODS ARE USED, THE SURFACE MAY BE LEFT WITH A MORE IRREGULAR SURFACE OF LARGE CLODS AND STONES.
·LIMING - APPLY LIME ACCORDING TO SOIL TEST RECOMMENDATIONS. IF THE PH (ACIDITY) OF THE SOIL IS NOT KNOWN, AN APPLICATION OF GROUND
AGRICULTURAL LIMESTONE AT THE RATE OF 1 TO 1 1/2 TONS/ACRE ON COARSE-TEXTURED SOILS AND 2-3 TONS/ACRE ON FINE-TEXTURED SOILS IS
USUALLY SUFFICIENT. APPLY LIMESTONE UNIFORMLY AND INCORPORATE INTO THE TOP 4-6 INCHES OF SOIL. SOILS WITH A PH OF 6 OR HIGHER NEED
NOT BE LIMED.
·FERTILIZER - BASE APPLICATION RATES ON SOIL TESTS. WHEN THESE ARE NOT POSSIBLE, APPLY A 10-10-10 GRADE FERTILIZER AT 700-1,00 LB/ACRE.
BOTH FERTILIZER AND LIME SHOULD BE INCORPORATED INTO THE TOP 4-6 INCHES OF SOIL. IF A HYDRAULIC SEEDER IS USED, DO NOT MIX SEED AND
FERTILIZER MORE THAN 30 MINUTES BEFORE APPLICATION.
·SURFACE ROUGHENING - IF RECENT TILLAGE OPERATIONS HAVE RESULTED IN A LOOSE SURFACE, ADDITIONAL ROUGHENING MAY NOT BE REQUIRED,
EXCEPT TO BREAK UP LARGE CLODS. IF RAINFALL CAUSES THE SURFACE TO BECOME SEALED OR CRUSTED, LOOSEN IT JUST PRIOR TO SEEDING BY
DISKING, RAKING, HARROWING, OR OTHER SUITABLE METHODS. GROOVE OR FURROW SLOPES STEEPER THAN 3:1 ON THE CONTOUR BEFORE SEEDING
(REFER TO THE NCDEQ EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL, PRACTICE 6.03, SURFACE ROUGHENING).
PLANT SELECTION
·SELECT AN APPROPRIATE SPECIES OR SPECIES MIXTURE FROM TABLE 6.10A FOR SEEDING IN LATE WINTER AND EARLY SPRING, TABLE 6.10B FOR
SUMMER, AND TABLE 6.10C FOR FALL.
·IN THE MOUNTAINS, DECEMBER AND JANUARY SEEDING HAVE POOR CHANCES OF SUCCESS. WHEN IT IS NECESSARY TO PLANT AT THESE TIMES, USE
RECOMMENDATIONS FOR FALL AND A SECURELY TACKED MULCH.
SEEDING
·EVENLY APPLY SEED USING A CYCLONE SEEDER (BROADCAST), DRILL, CULTIPACKER SEEDER, OR HYDROSEEDER. USE SEEDING RATES GIVEN IN TABLES
6.10A-6.10C. BROADCAST SEEDING AND HYDROSEEDING ARE APPROPRIATE FOR STEEL SLOPES WHERE EQUIPMENT CANNOT BE DRIVEN. HAND
BROADCASTING IS NOT RECOMMENDED BECAUSE OF THE DIFFICULTY IN ACHIEVING A UNIFORM DISTRIBUTION.
·SMALL GRAINS SHOULD BE PLANTED NO MORE THAN 1 INCH DEEP, AND GRASSES AND LEGUMES NO MORE THAN 1/2 INCH. BROADCAST SEED MUST BE
COVERED BY RAKING OR CHAIN DRAGGING, AND THEN LIGHTLY FIRMED WITH A ROLLER OR CULTIPACKER. HYDROSEEDED MIXTURES SHOULD INCLUDE
A WOOD FIBER (CELLULOSE) MULCH.
MULCHING
THE USE OF AN APPROPRIATE MULCH WILL HELP ENSURE ESTABLISHMENT UNDER NORMAL CONDITIONS, AND IS ESSENTIAL TO SEEDING SUCCESS UNDER
HARSH SITE CONDITIONS (REFER TO THE NCDEQ EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL, PRACTICE 6.14, MULCHING). HARSH
SITE CONDITIONS INCLUDE:
·SEEDING IN FALL FOR WINTER COVER (WOOD FIBER MULCHES ARE NOT CONSIDERED ADEQUATE FOR THIS USE),
·SLOPES STEEPER THAN 3:1,
·EXCESSIVELY HOT OR DRY WEATHER,
·ADVERSE SOILS (SHALLOW, ROCKY, OR HIGH IN CLAY OR SAND), AND
·AREAS RECEIVING CONCENTRATED FLOW.
IF THE AREA TO BE MULCHED IS SUBJECT TO CONCENTRATED WATERFLOW, AND IN CHANNELS, ANCHOR MULCH WITH NETTING (REFER TO THE NCDEQ
EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL, PRACTICE 6.14, MULCHING).
TEMPORARY SEEDING MAINTENANCE
RESEED AND MULCH AREAS WHERE SEEDING EMERGENCE IS POOR, OR WHERE EROSION OCCURS, AS SOON AS POSSIBLE. DO NOT MOW. PROTECT FROM
TRAFFIC AS MUCH AS POSSIBLE.

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 dispose of it properly. Haul all objectionable material to the
designated disposal area. Place 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 the fill in
lifts not to exceed 9 inches, and machine compact it. Over fill the embankment
6 inches 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 4inch Schedule 40 PVC pipe) on a firm, smooth
foundation of impervious soil. Do not use pervious material such as sand,
gravel, or crushed stone as backfill around the pipe. Place the fill material
around the pipe spillway in 4inch layers and compact it under and around
the pipe to at least the same density as the 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
joint 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 for maintenance.
7. Earthen spillwaysInstall the spillway in undisturbed soil to the greatest
extent possible. The achievement of planned elevations, grade, design width,
and entrance and exit channel slopes are critical to the successful operation
of the spillway. The spillway should be lined with laminated plastic or
impermeable geotextile fabric. The fabric 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 8inch staples or pins. The fabric
must be long enough to extend down the slope and exit onto stable ground.
The width of the fabric must be one piece, not joined or spliced; otherwise
water can get 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 upper 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. (Adapted from “A Manual for
Designing, Installing and Maintaining Skimmer Sediment Basins.” February,
1999. J. W. Faircloth & Son.).
8. InletsDischarge 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 efficiency
(References: Runoff Control Measures and Outlet Protection).
9. Erosion controlConstruct 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 areas above the crest of the principal
spillway immediately after construction (References: Surface Stabilization).
10. Install porous baffles as specified in Practice 6.65
11. After all the sedimentproducing 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 (References: Surface
Stabilization).

INSPECT SKIMMER SEDIMENT BASINS AT LEAST WEEKLY AND
AFTER EACH SIGNIFICANT (ONEHALF INCH OR GREATER)
RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE SEDIMENT
AND RESTORE THE BASIN TO ITS ORIGINAL DIMENSIONS WHEN
SEDIMENT ACCUMULATES TO ONEHALF THE HEIGHT OF THE
FIRST BAFFLE. 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.
REPAIR THE BAFFLES IF THEY ARE DAMAGED. REANCHOR THE
BAFFLES IF WATER 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 WITH A
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.

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
DISPOSE OF IT PROPERLY. HAUL ALL OBJECTIONABLE MATERIAL TO THE DESIGNATED DISPOSAL
AREA. PLACE 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 THE FILL IN LIFTS NOT TO EXCEED
9 INCHES, AND MACHINE COMPACT IT. OVER FILL THE EMBANKMENT 6 INCHES 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 4INCH SCHEDULE 40 PVC PIPE) ON A FIRM, SMOOTH FOUNDATION OF
IMPERVIOUS SOIL. DO NOT USE PERVIOUS MATERIAL SUCH AS SAND, GRAVEL, OR CRUSHED STONE
AS BACKFILL AROUND THE PIPE. PLACE THE FILL MATERIAL AROUND THE PIPE SPILLWAY IN 4INCH
LAYERS AND COMPACT IT UNDER AND AROUND THE PIPE TO AT LEAST THE SAME DENSITY AS THE
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 JOINT 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
FOR MAINTENANCE.
7.EARTHEN SPILLWAYSINSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST EXTENT
POSSIBLE. THE ACHIEVEMENT OF PLANNED ELEVATIONS, GRADE, DESIGN WIDTH, AND ENTRANCE
AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCCESSFUL OPERATION OF THE SPILLWAY. THE
SPILLWAY SHOULD BE LINED WITH LAMINATED PLASTIC OR IMPERMEABLE GEOTEXTILE FABRIC. THE
FABRIC 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 8INCH
STAPLES OR PINS. THE FABRIC MUST BE LONG ENOUGH TO EXTEND DOWN THE SLOPE AND EXIT
ONTO STABLE GROUND. THE WIDTH OF THE FABRIC MUST BE ONE PIECE, NOT JOINED OR SPLICED;
OTHERWISE WATER CAN GET 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 UPPER 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. (ADAPTED FROM “A MANUAL FOR DESIGNING, INSTALLING AND
MAINTAINING SKIMMER SEDIMENT BASINS.” FEBRUARY, 1999. J. W. FAIRCLOTH & SON.).
8.INLETSDISCHARGE 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 EFFICIENCY (REFERENCES: RUNOFF
CONTROL MEASURES AND OUTLET PROTECTION).
9.EROSION CONTROLCONSTRUCT 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
AREAS ABOVE THE CREST OF THE PRINCIPAL SPILLWAY IMMEDIATELY AFTER CONSTRUCTION
(REFERENCES: SURFACE STABILIZATION).
10.INSTALL POROUS BAFFLES AS SPECIFIED IN PRACTICE 6.65
11.AFTER ALL THE SEDIMENTPRODUCING 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 (REFERENCES: SURFACE STABILIZATION).

NOTES:
1.SEDIMENT BARRIERS: USE SEDIMENT FENCES OR OTHER BARRIERS WHERE NECESSARY TO RETAIN SEDIMENT.
2.TEMPORARY SEEDING: PROTECT TOPSOIL STOCKPILES BY TEMPORARILY SEEDING AS SOON AS POSSIBLE, NO MORE THAN
7 CALENDAR DAYS AFTER THE FORMATION OF THE STOCKPILE (NCG01 GROUND STABILIZATION).
3.PERMANENT VEGETATION: IF STOCKPILES WILL NOT BE USED WITHIN 90 DAYS THEY MUST BE STABILIZED WITH
PERMANENT VEGETATION TO CONTROL EROSION AND WEED GROWTH (PRACTICE 6.11, PERMANENT SEEDING).
