INSPECTION/MAINTENANCE/REMOVAL:
1. TEMPORARY CONCRETE WASHOUT FACILITIES ARE TO BE INSPECTED
BY THE RESIDENT ENGINEER DURING HIS/HER WEEKLY EROSION AND
SEDIMENT CONTROL INSPECTION, AFTER A STORM EVENT OF %"OR
GREATER AND AT THE END OF ANY DAY WHEN CONCRETE HAS BEEN
POURED ON THE CONSTRUCTION SITE. THE INSPECTOR IS TO ENSURE
THAT THERE ARE NO LEAKS, NO SPILLS AND THAT THE FACILITIES
CAPACITY HAS NOT YET BEEN COMPROMISED.
2. ANY OVERFLOWING OF THE WASHOUT FACILITIES ONTO THE GROUND
MUST BE CLEANED UP AND REMOVED WITHIN 24 HOURS OF
DISCOVERY.
3. IF A RAIN OR SNOW EVENT IS FORECASTED, A NON -COLLAPSING,
NON -WATER COLLECTING COVER SHALL BE PLACED OVER THE
WASHOUT FACILITY AND SECURED TO PREVENT ACCUMULATION AND
OVERFLOW OF PRECIPITATION.
4. CONTENTS OF EACH CONCRETE WASHOUT FACILITY ARE NOT TO
EXCEED 75% OF ITS DESIGNED CAPACITY. IF THE CONTENTS REACH
75% CAPACITY, DISCONTINUE POURING CONCRETE INTO THE
FACILITY UNTIL IT HAS BEEN CLEANED OUT.
5. ALLOW SLURRY TO EVAPORATE OR REMOVE FROM THE SITE IN A
SAFE MANNER (IE. VACUUM TRUCK). ALL HARDENED MATERIAL CAN
THEN BE REMOVED AND DISPOSED OF PROPERLY.
6. IF A LINED BASIN IS USED, IMMEDIATELY REPLACE THE LINER IF IT
BECOMES DAMAGED.
7. REMOVE TEMPORARY CONCRETE WASHOUT FACILITIES WHEN THEY
ARE NO LONGER NEEDED AND RESTORE THE DISTURBED AREAS TO

SILT FENCE INSTALLATION SPECIFICATIONS: """"" "" "•'"
MATERIALS:
1. USE SYNTHETIC FIBER FABRIC OF AT LEAST 95% BY WEIGHT OF POLYOLEFINS OR POLYESTER, WHICH IS
CERTIFIED BY THE MANUFACTURER OR SUPPLIER AS CONFORMING TO THE REQUIREMENTS IN ASTM D 6461.
2. SYNTHETIC FILTER FABRIC SHOULD CONTAIN ULTRAVIOLET RAY INHIBITORS AND STABILIZERS TO PROVIDE A
MINIMUM OF 6 MONTHS OF EXPECTED USABLE CONSTRUCTION LIFE AT A TEMPERATURE RANGE OF 0 TO 120
DEGREES FAHRENHEIT.
3. ENSURE THAT POSTS FOR SEDIMENT FENCES ARE 1.25 LB/FT STEEL WITH A MINIMUM LENGTH OF 5 FEET. MAKE
SURE THAT STEEL POSTS HAVE PROJECTIONS TO FACILITATE FASTENING THE FABRIC. USE SOIL STABILIZATION
PLATE WITH MIN. 15 GAUGE STEEL AND MIN. CROSS SECTION AREA OF 17 SQUARE INCHES.
4. FOR REINFORCEMENT OF STANDARD STRENGTH FILTER FABRIC, USE WIRE MESH WITH A MINIMUM 16 GUAGE AND
A MAXIMUM MESH SPACING OF 12 INCHES.
5. WIRE OR PLASTIC ZIP TIES SHOULD HAVE A MINIMUM 50 POUND TENSILE STRENGTH.
CONSTRUCTION:
1. DRIVE STEEL POST 24" INTO THE GROUND AND EXCAVATE A TRENCH UPHILL ALONG THE LINE OF THE POSTS
(MAX. 6- BETWEEN POSTS). REFER TO TRENCH TABLE.
2. SUPPORT FILTER FABRIC WITH WIRE MESH FASTENED SECURELY TO THE UPSLOPE SIDE OF THE POSTS. EXTEND
THE WIRE MESH SUPPORT TO THE BOTTOM OF THE 8" TRENCH.
3. ATTACH THE FILTER FABRIC TO THE WIRE MESH ON THE UPSLOPE SIDE OF THE FENCE POST AND EXTEND THE
BOTTOM OF THE FABRIC Y INCHES INTO THE TRENCH AND X INCHES ACROSS THE BOTTOM OF THE TRENCH (SEE
CROSS SECTION VIEW DETAIL).
4. BACKFILL THE TRENCH AND COMPACT THE SOIL FIRMLY TO ANCHOR THE BOTTOM OF THE SILT FENCE SO THAT
RUNOFF IS FORCED TO GO THROUGH THE FENCE AND CANNOT GO UNDER IT.
5. ENSURE THE HEIGHT OF THE SEDIMENT FENCE DOES NOT EXCEED 36" ABOVE THE GROUND SURFACE. (HIGHER
FENCES MAY IMPOUND VOLUMES OF WATER SUFFICIENT TO CAUSE FAILURE OF THE STRUCTURE).
6. CONSTRUCT THE FILTER FABRIC FROM A CONTINUOUS ROLL, CUT TO LENTH OF THE BARRIER TO AVOID JOINTS.
WHEN JOINTS ARE NECESARY, SECURELY FASTEN THE FILTER FABRIC ONLY AT A SUPPORT POST WITH A
MINIMUM OF 4 FEET OF OVERLAP TO THE NEXT POST.
7. DO NOT ATTACH FILTER FABRIC TO TREES.
8. DO NOT INSTALL SILT FENCE ACROSS STREAMS, DITCHES, WATERWAYS, OR OTHER AREAS OF CONCENTRATED
FLOW.
MAINTENANCE:
1. INSPECT SILT FENCE EVERY SEVEN DAYS AND WITHIN 24 HOURS AFTER EVERY RAINFALL EVENT 1/2 INCH OR
GREATER.
2. SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR BECOME INEFFECTIVE, REPLACE
IT PROMPTLY.
3. REMOVE ACCUMULATED SEDIMENT AS NECESSARY AND WHEN 1/3 OF THE STORAGE CAPACITY IS REACHED TO
PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE PRESSURE ON THE FENCE. TAKE
CARE TO AVOID UNDERMINING THE FENCE DURING CLEANOUT. REMOVE ALL FENCING MATERIALS AND UNSTABLE
SEDIMENT DEPOSITS AND BRING THE AREA TO GRADE AND STABILIZE IT AFTER THE CONTRIBUTING DRAINAGE
AREA HAS BEEN PROPERLY STABILIZED.

GROUND STABILIZATION AND MATERIALS HANDLING PRACTICES FOR COMPLIANCE WITH
THE NCG01 CONSTRUCTION GENERAL PERMIT
Implementing the details and specifications on this plan sheet will result in the construction
activity being considered compliant with the Ground Stabilization and Materials Handling
sections of the NCGO1 Construction General Permit (Sections E and F, respectively). The
permittee shall comply with the Erosion and Sediment Control plan approved by the
delegated authority having jurisdiction. All details and specifications shown on this sheet
may not apply depending on site conditions and the delegated authority having jurisdiction.

Note: After the permanent cessation of construction activities, any areas with temporary
ground stabilization shall be converted to permanent ground stabilization as soon as
practicable but in no case longer than 90 calendar days after the last land disturbing
activity. Temporary ground stabilization shall be maintained in a manner to render the
surface stable against accelerated erosion until permanent ground stabilization is achieved.
GROUND STABILIZATION SPECIFICATION
Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the
techniques in the table below:
POLYACRYLAMIDES (PAMS) AND FLOCCULANTS
1. 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.
EQUIPMENT AND VEHICLE MAINTENANCE
1. 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 WASTE
1. 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 WASTE
1. 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 TOILETS
1. 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 foot
offset is not attainable, provide relocation of portable toilet behind silt fence or place
on a gravel pad and surround with sand bags.
2. Provide staking or anchoring of portable toilets during periods of high winds or in high
foot 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 replace
with properly operating unit.
EARTHEN STOCKPILE MANAGEMENT
1. Show stockpile locations on plans. Locate earthen -material stockpile areas at least
50 feet away from storm drain inlets, sediment basins, perimeter sediment controls
and surface waters unless it can be shown no other alternatives are reasonably
available.
2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of
five 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 defined
as vegetative, physical or chemical coverage techniques that will restrain accelerated

CONCRETE WASHOUTS
1. 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 within
lot perimeter silt fence.
4. Install temporary concrete washouts per local requirements, where applicable. If an
alternate method or product is to be used, contact your approval authority for
review and approval. If local standard details are not available, use one of the two
types of temporary concrete washouts provided on this detail.
5. Do not use concrete washouts for dewatering or storing defective curb or sidewalk
sections. Stormwater accumulated within the washout may not be pumped into or
discharged to the storm drain system or receiving surface waters. Liquid waste must
be pumped out and removed from project.
6. Locate washouts at least 50 feet from storm drain inlets and surface waters unless it
can 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 receive
spills or overflow.
7. Locate washouts in an easily accessible area, on level ground and install a stone
entrance pad in front of the washout. Additional controls may be required by the
approving authority.
8. Install at least one sign directing concrete trucks to the washout within the project
limits. Post signage on the washout itself to identify this location.
9. Remove leavings from the washout when at approximately 75% capacity to limit
overflow events. Replace the tarp, sand bags or other temporary structural
components when no longer functional. When utilizing alternative or proprietary
products, follow manufacturer's instructions.
10. At the completion of the concrete work, remove remaining leavings and dispose of
in an approved disposal facility. Fill pit, if applicable, and stabilize any disturbance
caused by removal of washout.
HERBICIDES, PESTICIDES AND RODENTICIDES
1. 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 of
accidental poisoning.
3. Do not store herbicides, pesticides and rodenticides in areas where flooding is
possible or where they may spill or leak into wells, stormwater drains, ground water
or surface water. If a spill occurs, clean area immediately.
4. Do not stockpile these materials onsite.
HAZARDOUS AND TOXIC WASTE
1. 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.
