3. WIDTH - 12 FT. MINIMUM OR FULL WIDTH AT ACCESS POINTS OF THE VEHICULAR ENTRANCE AND EXIT AREA, WHICHEVER IS GREATER.

4. LENGTH - 50 FT. MINIMUM.

5. LOCATION - LOCATE CONSTRUCTION ENTRANCES AND EXITS TO LIMIT SEDIMENT FROM LEAVING THE SITE AND TO PROVIDE FOR MAXIMUM UTILITY BY ALL CONSTRUCTION VEHICLES. AVOID STEEP GRADES AND

ENTRANCES AT CURVES IN PUBLIC ROADS. CONTRACTOR SHALL INSTALL ADDITIONAL GRAVEL CONSTRUCTION ENTRANCES NOT INDICATED ON THE PLANS REQUIRED FOR STAGING AND/OR BORROW AREAS AND

MAINTAIN AT NO ADDITIONAL EXPENSE TO THE OWNER.

6. CONTRACTOR SHALL SUPPLEMENT AND MAINTAIN GRAVEL CONSTRUCTION ENTRANCES AT THE CONTRACTOR'S EXPENSE UNTIL FINAL ACCEPTANCE.

7. THE CONTRACTOR SHALL MAINTAIN THE GRAVEL PAD IN A CONDITION TO PREVENT MUD OR SEDIMENT FROM LEAVING THE CONSTRUCTION SITE. THIS MAY REQUIRE PERIODIC TOPDRESSING WITH 2-INCH STONE.

AFTER EACH RAINFALL, INSPECT ANY STRUCTURE USED TO TRAP SEDIMENT AND CLEAN IT OUT AS NECESSARY. IMMEDIATELY REMOVE ANY OBJECTIONABLE MATERIALS SPILLED, WASHED, OR TRACKED ONTO

PUBLIC ROADWAYS.

8. WASHING - IF CONDITIONS AT THE SITE ARE SUCH THAT MOST OF THE MUD AND SEDIMENT ARE NOT REMOVED BY VEHICLES TRAVELING OVER THE GRAVEL, THE TIRES SHOULD BE WASHED. WASHING SHOULD BE

DONE ON AN AREA STABILIZED WITH CRUSHED STONE THAT DRAINS INTO A SEDIMENT TRAP OR OTHER SUITABLE DISPOSAL AREA. A WASH RACK MAY ALSO BE USED TO MAKE WASHING MORE CONVENIENT AND

EFFECTIVE. SEE DETAIL EC.2B.

CONSTRUCTION

1. CONSTRUCT THE SEDIMENT BARRIER OF STANDARD STRENGTH OR EXTRA STRENGTH

SYNTHETIC FILTER FABRICS.

2. ENSURE THAT THE HEIGHT OF THE SEDIMENT FENCE DOES NOT EXCEED 24 INCHES

ABOVE THE GROUND SURFACE. (HIGHER FENCES MAY IMPOUND VOLUMES OF WATER

SUFFICIENT TO CAUSE FAILURE OF THE STRUCTURE.)

3. CONSTRUCT THE FILTER FABRIC FROM A CONTINUOUS ROLL CUT TO THE LENGTH OF

BARRIER TO AVOID JOINTS. WHEN JOINTS ARE NECESSARY, SECURELY FASTEN THE

FILTER CLOTH ONLY AT SUPPORT POST WITH 4 FEET MINIMUM OVERLAP TO THE NEXT

POST.

4. SUPPORT STANDARD STRENGTH FILTER FABRIC BY WIRE MESH FASTENED SECURELY

TO THE UPSLOPE SIDE OF THE POSTS. EXTEND THE WIRE MESH SUPPORT TO THE

BOTTOM OF THE TRENCH. FASTEN THE WIRE REINFORCEMENT, THEN FABRIC ON THE

UPSLOPE SIDE OF THE FENCE POST. WIRE OR PLASTIC SIP TIES SHOULD HAVE MINIMUM

50 POUND TENSILE STRENGTH.

5. WHEN A WIRE MESH SUPPORT FENCE IS USED, SPACE POSTS A MAXIMUM OF 8 FEET

APART. SUPPORT POSTS SHOULD BE DRIVEN SECURELY INTO THE GROUND A MINIMUM

OF 24 INCHES.

6. EXTRA STRENGTH FILTER FABRIC WITH 6 FEET POST SPACING DOES NOT REQUIRE WIRE

MESH SUPPORT FENCE. SECURELY FASTEN THE FILTER FABRIC DIRECTLY TO POSTS.

WIRE OR PLASTIC ZIP TIES SHOULD HAVE MINIMUM 50 POUND TENSILE STRENGTH.

7. EXCAVATE A TRENCH APPROXIMATELY 4 INCHES WIDE AND 8 INCHES DEEP ALONG THE

PROPOSED LINE OF POSTS AND UP-SLOPE FROM THE BARRIER.

8. PLACE 12 INCHES OF THE FABRIC ALONG THE BOTTOM AND SIDE OF THE TRENCH.

9. BACKFILL THE TRENCH WITH SOIL PLACED OVER THE FILTER FABRIC AND COMPACT.

THOROUGH COMPACTION OF THE BACKFILL IS CRITICAL TO SILT FENCE PERFORMANCE.

10. DO NOT ATTACH FILTER FABRIC TO EXISTING TREES.

INSTALLATION

1. THE BASE OF BOTH END POSTS SHOULD BE AT LEAST ONE FOOT HIGHER THAN THE MIDDLE OF

THE FENCE. CHECK WITH LEVEL IF NECESSARY.

2. INSTALL POSTS 4 FEET APART IN CRITICAL AREAS AND 6 FEET APART ON STANDARD

APPLICATIONS.

3. INSTALL POSTS 2 FEET DEEP ON THE DOWNSTREAM SIDE OF THE SILT FENCE AND AS CLOSE AS

POSSIBLE TO THE FABRIC, ENABLING POSTS TO SUPPORT THE FABRIC FROM UPSTREAM WATER

PRESSURE.

4. INSTALL POSTS WITH THE NIPPLES FACING AWAY FROM THE SILT FABRIC.

5. ATTACH THE FABRIC TO EACH POST WITH THREE TIES, ALL SPACED WITHIN THE TOP 8 INCHES OF

THE FABRIC. ATTACH EACH TIE DIAGONALLY 45 DEGREES THROUGH THE FABRIC, WITH EACH

PUNCTURE AT LEAST 1 INCH VERTICALLY APART. ALSO, EACH TIE SHOULD BE POSITIONED TO

HANG ON A POST NIPPLE WHEN TIGHTENED TO PREVENT SAGGING.

6. WRAP APPROXIMATELY 6 INCHES OF FABRIC AROUND THE END POSTS AND SECURE WITH 3 TIES.

7. NO MORE THAN 24 INCHES OF A 36 INCH FABRIC IS ALLOWED ABOVE GROUND LEVEL.

8. THE INSTALLATION SHOULD BE CHECKED AND CORRECTED FOR ANY DEVIATIONS BEFORE

COMPACTIONS.

9. COMPACTION IS VITALLY IMPORTANT FOR EFFECTIVE RESULTS. COMPACT THE SOIL

IMMEDIATELY NEXT TO THE SILT FENCE FABRIC WITH THE FRONT WHEEL OF THE TRACTOR, SKID

STEER, OR ROLLER EXERTING AT LEAST 60 POUNDS PER SQUARE INCH. COMPACT THE

UPSTREAM SIDE FIRST, AND THEN EACH SIDE TWICE FOR A TOTAL OF 4 TRIPS.

MAINTENANCE

INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY REPAIRS

IMMEDIATELY. SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR

BECOME INEFFECTIVE, REPLACE IT PROMPTLY. REMOVE SEDIMENT DEPOSITS AS NECESSARY TO

PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE PRESSURE ON THE

FENCE. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING CLEAN-OUT. REMOVE ALL FENCING

MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND BRING THE AREA TO GRADE AND STABILIZE IT

AFTER THE CONTRIBUTING DRAINAGE AREA HAS PROPERLY STABILIZED.

STONE CHECK DAM

CONSTRUCTION SPECIFICATIONS

1. PLACE NONWOVEN GEOTEXTILE UNDER THE BOTTOM AND SIDES OF THE DAM PRIOR TO

PLACEMENT OF STONE. CONSTRUCT THE CHECK DAM WITH WASHED 4 TO 7 INCH STONE

OR EQUIVALENT RECYCLED CONCRETE (WITHOUT REBAR) WITH SIDE SLOPES OF 2:1 OR

FLATTER AND A MINIMUM TOP WIDTH OF 12 INCHES. PLACE THE STONE SO THAT IT

COMPLETELY COVERS THE WIDTH OF THE CHANNEL AND CHANNEL BANKS. FORM THE

WEIR SO THAT TOP OF THE OUTLET CREST IS APPROXIMATELY 6 INCHES LOWER THAN

THE OUTER EDGES. LINE THE UPSTREAM FACE OF THE DAM WITH A 1 FOOT THICK

LAYER OF WASHED AGGREGATE (

3

4

TO 1

1

2

INCH).

2. SET THE HEIGHT FOR THE WEIR CREST EQUAL TO ONE-HALF THE DEPTH OF THE

CHANNEL OR DITCH. TO AVOID SCOUR, THE MAXIMUM HEIGHT OF THE WEIR CREST

MUST NOT EXCEED 2.0 FEET.

3. REMOVE ACCUMULATED SEDIMENT WHEN IT REACHES ONE-HALF OF THE HEIGHT OF

THE WEIR CREST. MAINTAIN LINE, GRADE, AND CROSS SECTION.

MAINTENANCE

THE STONE CHECK DAM IS NOT A SEDIMENT TAPPING PRACTICE; HOWEVER, SOME

SEDIMENT MAY ACCUMULATE BEHIND THE CHECK DAM. ACCUMULATED SEDIMENT MUST BE

REMOVED WHEN IT REACHES ONE-HALF OF THE HEIGHT OF THE WEIR CREST. LINE, GRADE,

AND CROSS SECTION MUST BE MAINTAINED.

CHECK DAM REMOVAL

IN TEMPORARY SWALES AND CHANNELS, REMOVE CHECK DAM(S) WHEN NO LONGER

NEEDED. IN PERMANENT CHANNELS, CHECK DAMS MAY BE REMOVED WHEN PERMANENT

LINING IS INSTALLED. IN THE CASE OF GRASS-LINED CHANNELS, CHECK DAM MAY BE

REMOVED WHEN THE GRASS HAS MATURED SUFFICIENTLY TO PROTECT THE SWALE OR

CHANNEL. SEED AND INSTALL SOIL STABILIZATION MATTING OR SOD IN THE AREAS

DISTURBED BY THE REMOVAL OF THE CHECK DAM.

CLOGGED OR TORN. IF PONDING BECOMES EXCESSIVE, THE SOCK MAY NEED TO BE REPLACED WITH A LARGER DIAMETER OR A DIFFERENT MEASURE. THE SOCK NEEDS TO BE REINSTALLED IF UNDERMINED OR

DISLODGED. THE COMPOST SOCK SHALL BE INSPECTED UNTIL LAND DISTURBANCE IS COMPLETE AND THE AREA ABOVE THE MEASURE HAS BEEN PERMANENTLY STABILIZED.

DISPOSAL/RECYCLING

COMPOST MEDIA IS A COMPOSTED ORGANIC PRODUCT RECYCLED AND MANUFACTURED FROM LOCALLY GENERATED ORGANIC, NATURAL, AND BIOLOGICALLY BASED MATERIALS. ONCE ALL SOIL HAS BEEN

STABILIZED AND CONSTRUCTION ACTIVITY HAS BEEN COMPLETED, THE COMPOST MEDIA MAY BE DISPERSED WITH A LOADER, RAKE, BULLDOZER OR SIMILAR DEVICE AND MAY BE INCORPORATED INTO THE SOIL AS

AN AMENDMENT OR LEFT ON THE SOIL SURFACE TO AID IN PERMANENT SEEDING OR LANDSCAPING. LEAVING THE COMPOST MEDIA ON SITE REDUCES REMOVAL AND DISPOSAL COSTS COMPARED TO OTHER

SEDIMENT CONTROL DEVICES. THE MESH NETTING MATERIAL WILL BE EXTRACTED FROM THE MEDIA AND DISPOSED OF PROPERLY. THE PHOTODEGRADABLE MESH NETTING MATERIAL WILL DEGRADE IN 2 TO 5

YEARS IF LEFT ON SITE. BIODEGRADABLE MESH NETTING MATERIAL IS AVAILABLE AND DOES NOT NEED TO BE EXTRACTED AND DISPOSED OF, AS IT WILL COMPLETELY DECOMPOSE IN APPROXIMATELY 6 TO 12

MONTHS. USING BIODEGRADABLE COMPOST SOCKS COMPLETELY ELIMINATES THE NEED AND COST OF REMOVAL AND DISPOSAL.

NCG01 GROUND STABILIZATION AND MATERIALS HANDLING EFFECTIVE: 04/01/19

GROUND STABILIZATION AND MATERIALS HANDLING PRACTICES FOR COMPLIANCE WITHTHE NCG01 CONSTRUCTION GENERAL PERMITImplementing the details and specifications on this plan sheet will result in the constructionactivity being considered compliant with the Ground Stabilization and Materials Handlingsections of the NCG01 Construction General Permit (Sections E and F, respectively). Thepermittee shall comply with the Erosion and Sediment Control plan approved by thedelegated authority having jurisdiction. All details and specifications shown on this sheetmay not apply depending on site conditions and the delegated authority having jurisdiction.

GROUND STABILIZATION SPECIFICATIONStabilize the ground sufficiently so that rain will not dislodge the soil. Use one of thetechniques in the table below:

POLYACRYLAMIDES (PAMS) AND FLOCCULANTS1. Select flocculants that are appropriate for the soils being exposed during

construction, selecting from the NC DWR List of Approved PAMS/Flocculants.2. Apply flocculants at or before the inlets to Erosion and Sediment Control Measures.3. Apply flocculants at the concentrations specified in the NC DWR List of Approved

PAMS/Flocculants and in accordance with the manufacturer's instructions.4. Provide ponding area for containment of treated Stormwater before discharging

offsite.5. Store flocculants in leak-proof containers that are kept under storm-resistant cover

or surrounded by secondary containment structures.

HAZARDOUS AND TOXIC WASTE1. Create designated hazardous waste collection areas on-site.2. Place hazardous waste containers under cover or in secondary containment.3. Do not store hazardous chemicals, drums or bagged materials directly on the ground.

EQUIPMENT AND VEHICLE MAINTENANCE1. Maintain vehicles and equipment to prevent discharge of fluids.2. Provide drip pans under any stored equipment.3. Identify leaks and repair as soon as feasible, or remove leaking equipment from the

project.4. Collect all spent fluids, store in separate containers and properly dispose as

hazardous waste (recycle when possible).5. Remove leaking vehicles and construction equipment from service until the problem

has been corrected.6. Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products

to a recycling or disposal center that handles these materials.

LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE1. Never bury or burn waste. Place litter and debris in approved waste containers.2. Provide a sufficient number and size of waste containers (e.g dumpster, trash

receptacle) on site to contain construction and domestic wastes.3. Locate waste containers at least 50 feet away from storm drain inlets and surface

waters unless no other alternatives are reasonably available.4. Locate waste containers on areas that do not receive substantial amounts of runoff

from upland areas and does not drain directly to a storm drain, stream or wetland.5. Cover waste containers at the end of each workday and before storm events or

provide secondary containment. Repair or replace damaged waste containers.6. Anchor all lightweight items in waste containers during times of high winds.7. Empty waste containers as needed to prevent overflow. Clean up immediately if

containers overflow.8. Dispose waste off-site at an approved disposal facility.9. On business days, clean up and dispose of waste in designated waste containers.

PAINT AND OTHER LIQUID WASTE1. Do not dump paint and other liquid waste into storm drains, streams or wetlands.2. Locate paint washouts at least 50 feet away from storm drain inlets and surface

waters unless no other alternatives are reasonably available.3. Contain liquid wastes in a controlled area.4. Containment must be labeled, sized and placed appropriately for the needs of site.5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes from

construction sites.

PORTABLE TOILETS1. Install portable toilets on level ground, at least 50 feet away from storm drains,

streams or wetlands unless there is no alternative reasonably available. If 50 footoffset is not attainable, provide relocation of portable toilet behind silt fence or placeon a gravel pad and surround with sand bags.

2. Provide staking or anchoring of portable toilets during periods of high winds or in highfoot traffic areas.

3. Monitor portable toilets for leaking and properly dispose of any leaked material.Utilize a licensed sanitary waste hauler to remove leaking portable toilets and replacewith properly operating unit.

HERBICIDES, PESTICIDES AND RODENTICIDES1. Store and apply herbicides, pesticides and rodenticides in accordance with label

restrictions.2. Store herbicides, pesticides and rodenticides in their original containers with the

label, which lists directions for use, ingredients and first aid steps in case ofaccidental poisoning.

3. Do not store herbicides, pesticides and rodenticides in areas where flooding ispossible or where they may spill or leak into wells, stormwater drains, ground wateror surface water. If a spill occurs, clean area immediately.

4. Do not stockpile these materials onsite.

CONCRETE WASHOUTS1. Do not discharge concrete or cement slurry from the site.2. Dispose of, or recycle settled, hardened concrete residue in accordance with local

and state solid waste regulations and at an approved facility.3. Manage washout from mortar mixers in accordance with the above item and in

addition place the mixer and associated materials on impervious barrier and withinlot perimeter silt fence.

4. Install temporary concrete washouts per local requirements, where applicable. If analternate method or product is to be used, contact your approval authority forreview and approval. If local standard details are not available, use one of the twotypes of temporary concrete washouts provided on this detail.

5. Do not use concrete washouts for dewatering or storing defective curb or sidewalksections. Stormwater accumulated within the washout may not be pumped into ordischarged to the storm drain system or receiving surface waters. Liquid waste mustbe pumped out and removed from project.

6. Locate washouts at least 50 feet from storm drain inlets and surface waters unless itcan be shown that no other alternatives are reasonably available. At a minimum,install protection of storm drain inlet(s) closest to the washout which could receivespills or overflow.

7. Locate washouts in an easily accessible area, on level ground and install a stoneentrance pad in front of the washout. Additional controls may be required by theapproving authority.

8. Install at least one sign directing concrete trucks to the washout within the projectlimits. Post signage on the washout itself to identify this location.

9. Remove leavings from the washout when at approximately 75% capacity to limitoverflow events. Replace the tarp, sand bags or other temporary structuralcomponents when no longer functional. When utilizing alternative or proprietaryproducts, follow manufacturer's instructions.

10. At the completion of the concrete work, remove remaining leavings and dispose ofin an approved disposal facility. Fill pit, if applicable, and stabilize any disturbancecaused by removal of washout.

EARTHEN STOCKPILE MANAGEMENT1. Show stockpile locations on plans. Locate earthen-material stockpile areas at least

50 feet away from storm drain inlets, sediment basins, perimeter sediment controlsand surface waters unless it can be shown no other alternatives are reasonablyavailable.

2. Protect stockpile with silt fence installed along toe of slope with a minimum offset offive feet from the toe of stockpile.

3. Provide stable stone access point when feasible.4. Stabilize stockpile within the timeframes provided on this sheet and in accordance

with the approved plan and any additional requirements. Soil stabilization is definedas vegetative, physical or chemical coverage techniques that will restrain acceleratederosion on disturbed soils for temporary or permanent control needs.
