PLANNING TIE THE ENDS OF A SEDIMENT FENCE INTO HIGHER GROUND TO PREVENT FLOW
CONSIDERATIONS: AROUND THE END OF THE FENCE BEFORE THE POOL REACHES DESIGN LEVEL.
CURLING EACH END OF THE FENCE UPHILL IN A "J" PATTERN MAY BE
APPROPRIATE TO PREVENT END FLOW.
A SEDIMENT FENCE ACTS AS A DIVERSION IF PLACED SLIGHTLY OFF THE
CONTOUR. A MAXIMUM SLOPE OF 2 PERCENT IS RECOMMENDED.
THE ANCHORING OF THE TOE OF THE FENCE SHOULD BE REINFORCED WITH 12
INCHES OF NCDOT #5 WASHED STONE WHEN FLOW WILL RUN PARALLEL TO
THE TOE OF THE FENCE. THE TOE OF THE FABRIC MUST BE ANCHORED IN A
TRENCH BACK FILLED WITH COMPACTED EARTH.
PROVIDE A RIPRAP SPLASH PAD OR OTHER OUTLET PROTECTION DEVICE FOR
ANY POINT WHERE FLOW MAY OVERTOP THE SEDIMENT FENCE, SUCH AS
NATURAL DEPRESSIONS OR SWALES. ENSURE THAT THE MAXIMUM HEIGHT OF
THE FENCE AT A PROTECTED, REINFORCED OUTLET DOES NOT EXCEED 2 FEET
AND THAT SUPPORT POST SPACING DOES NOT EXCEED 4 FEET.
NOTE: WOODEN STAKES MUST BE APPROVED BY ENGINEER OR SPECIFICALLY
NOTED IN PLANS.
MAINTENANCE: INSPECT TEMPORARY SEDIMENT TRAPS AT LEAST WEEKLY AND AFTER EACH
SIGNIFICANT RAIN EVENT AND REPAIR 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 CLEANOUT.
REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND

Major Elements of DWQ Construction General Permit
This document contains the major elements of the recently -revised North Carolina Division of Water Quality (DWQ) Construction 2 SEDIMENT FENCE 3 RIP RAP OUTLET PROTECTION
General Permit (NCGO1) with emphasis placed on those elements that differ from the previous permit (expiration on August 2, �C!9. 3 NTS�9.3
NTS
2011). Since the summary list below cannot contain details of every change, the complete Permit should be used to assure full
implementation. See: http://portal.ncdenr.org/web/wq/ws/su/construction

* "Extensions of time may be approved by the permitting authority
based on weather or other site-specific conditions that make compliance
impracticable." (Section II.B(2)(b))
The major change in the Permit from the previous one is the shorter
times to apply ground stabilization such as mulch, wheat straw, or
grasses. The NC laws and rules relating to the Sediment Act require,
in most places, ground stabilization within 21 days. Based on the new
EPA requirements and 9 -months' work with a permit advisory group,
CTAG, the Division and EPA -developed permit, now contains
requirements for ground cover within 14, and in some places, 7 days.
2) Building Wastes Handling
• No paint or liquid wastes in stream or storm drains
• Dedicated areas for demolition, construction and other
wastes must be located 50' from storm drains and streams
unless no reasonable alternatives available.
• Earthen -material stockpiles must be located 50' from storm
drains and streams unless no reasonable alternatives
available.
• Concrete materials must be controlled to avoid contact with
surface waters, wetlands, or buffers.
3) Discharges to Federally -listed Waters
• Requirements are the same as in previous permit.
• The permit allows reduction from the 20 acre minimum if
the Director of DWQ determines that other BMPs provide
equivalent protection.
Major Elements of DWQ Construction General Permit- Continued
4) Inspections
• Same weekly inspection requirements
• Same rain gauge & inspections after 0.5" rain event
• Inspections are only required during "normal business
hours"
• Inspection reports must be available on-site during
business hours unless a site-specific exemption is
approved.
• Records must be kept for 3 years and available upon
request.
• Electronically -available records may be substituted
under certain conditions.
5) Implementation of New Permit Conditions
• Projects permitted under the previous permit can
continue to follow the previously -permitted conditions.
• Complete applications received prior to August 3, 2011
can follow conditions of approved application.
• Applications received after August 2, 2011 must comply
with new permit conditions.

August 4, 2011
6) Conditions in Erosion & Sedimentation Control Plans*
Designation on the plans where the 7 and 14 -day ground
stabilization requirements of the NPDES permit apply
Designation on the plans where basins that comply with the
surface -withdrawal requirements of the NPDES permit are
located.
7) Building Wastes Handling
• No paint or liquid wastes in stream or storm drains
• Dedicated areas for demolition, construction and other
wastes located 50' from storm drains and streams unless
no reasonable alternatives are available.
• Earthen -material stockpiles located 50' from storm
drains unless no reasonable alternatives available.
• Concrete materials must be controlled to avoid contact
with surface waters, wetlands, or buffers.
8) Sediment Basins
• Outlet structures must withdraw from basin surface
unless drainage area is less than 1 acre.
• Use only DWQ-approved flocculants.
* In order for the E&SC Plan to satisfy the conditions of the Construction General permit, it must identify areas where the ground stabilization requirements apply and the
location of the basins where the surface -withdrawal requirements apply.

DEFINITION: A PERMANENT RIDGE OR EXCAVATED CHANNEL OR COMBINATION RIDGE AND CHANNEL CONSTRUCTED ON A DESIGNED
GRADE ACROSS SLOPING LAND.
PURPOSE: TO DIVERT WATER FROM AREAS WHERE IT IS IN EXCESS TO LOCATIONS WHERE IT CAN BE USED OR RELEASED WITHOUT
EROSION OR FLOOD DAMAGE.
CONDITIONS WHERE THIS PERMANENT SITE DEVELOPMENT PRACTICE APPLIES TO CONSTRUCTION AREAS WHERE RUNOFF CAN BE DIVERTED AND
PRACTICE APPLIES: USED OR DISPOSED OF SAFELY TO PREVENT FLOOD DAMAGE OR EROSION AND SEDIMENTATION DAMAGE. SPECIFIC
LOCATIONS AND CONDITIONS INCLUDE:
—ABOVE STEEP SLOPES TO LIMIT SURFACE RUNOFF ONTO THE SLOPE;
—ACROSS LONG SLOPES TO REDUCE SLOPE LENGTH TO PREVENT GULLY EROSION;
—BELOW STEEP GRADES WHERE FLOODING, SEEPAGE PROBLEMS OR SEDIMENT DEPOSITION MAY OCCUR;
—AROUND BUILDINGS OR AREAS THAT ARE SUBJECT TO DAMAGE FROM RUNOFF.
PLANNING CONSIDERATIONS: PERMANENT DIVERSIONS SHOULD BE PLANNED AS PART OF INITIAL SITE DEVELOPMENT. THEY ARE PRINCIPALLY RUNOFF
CONTROL MEASURES THAT SUBDIVIDE THE SITE INTO SPECIFIC DRAINAGE AREAS. PERMANENT DIVERSIONS CAN BE
INSTALLED AS TEMPORARY DIVERSIONS UNTIL THE SITE IS STABILIZED THEN COMPLETED AS A PERMANENT MEASURE, OR
THEY CAN BE INSTALLED IN FINAL FORM DURING THE INITIAL CONSTRUCTION OPERATION. THE AMOUNT OF SEDIMENT
ANTICIPATED AND THE MAINTENANCE REQUIRED AS A RESULT OF CONSTRUCTION OPERATIONS WILL DETERMINE WHICH
APPROACH SHOULD BE USED. STABILIZE PERMANENT DIVERSIONS WITH VEGETATION OR MATERIALS SUCH AS RIPRAP,
PAVING STONE, OR CONCRETE AS SOON AS POSSIBLE AFTER INSTALLATION. BASE THE LOCATION, TYPE OF
STABILIZATION, AND DIVERSION CONFIGURATION ON FINAL SITE CONDITIONS. EVALUATE FUNCTION, NEED, VELOCITY
CONTROL, OUTLET STABILITY, AND SITE AESTHETICS. WHEN PROPERLY LOCATED, LAND FORMS SUCH AS LANDSCAPE
ISLANDS, SWALES OR RIDGES CAN BE USED EFFECTIVELY AS PERMANENT DIVERSIONS. BASE THE CAPACITY OF A
DIVERSION ON THE RUNOFF CHARACTERISTICS OF THE SITE AND THE POTENTIAL DAMAGE AFTER DEVELOPMENT. CONSIDER
DESIGNING AN EMERGENCY OVERFLOW SECTION OR BYPASS AREA TO LIMIT DAMAGE FROM STORMS THAT EXCEED THE
DESIGN STORM. THE OVERFLOW SECTION MAY BE DESIGNED AS A WEIR WITH RIPRAP PROTECTION.
MAINTENANCE: INSPECT PERMANENT DIVERSIONS AFTER EVERY RAINFALL DURING THE CONSTRUCTION OPERATION. IMMEDIATELY REMOVE
ANY OBSTRUCTIONS FROM THE FLOW AREA AND REPAIR THE DIVERSION RIDGE. CHECK OUTLETS AND MAKE TIMELY
REPAIRS AS NEEDED. MAINTAIN THE VEGETATION IN A VIGOROUS, HEALTHY CONDITION AT ALL TIMES.

STONE SECTION
CONSTRUCTION 1. PLACE STONE TO THE LINES AND DIMENSIONS SHOWN IN THE PLAN ON A FILTER FABRIC FOUNDATION.
SPECIFICATIONS: 2. KEEP THE CENTER STONE SECTION AT LEAST 9 INCHES BELOW NATRUAL GROUND LEVEL WHERE THE
DAM ABUTS THE CHANNEL BANKS.
3. EXTEND STONE AT LEAST 1.5 FT BEYOND THE DITCH BANKS TO KEEP OVERFLOW WATER FROM
UNDERCUTTING THE DAM AS IT RE—ENTERS THE CHANNEL.
4. SET SPACING BETWEEN DAMS TO ASSURE THAT THE ELEVATION AT THE TOP OF THE LOWER DAM IS
THE SAME AS THE TOE ELEVATION OF THE UPPER DAM.
5. PROTECT THE CHANNEL DOWNSTREAM FROM THE LOWEST CHECK DAM, CONSIDERING THAT WATER WILL
FLOW OVER AND AROUND THE DAM.
6. MAKE SURE THAT THE CHANNEL REACH ABOVE THE MOST UPSTREAM DAM IS STABLE.
7. ENSURE THAT THE CHANNEL APPURTENANCES, SUCH AS CULVERT ENTRANCES BELOW CHECK DAMS,
ARE NOT SUBJECT TO DAMAGE OR BLOCKAGE FROM DISPLACED STONES.
MAINTENANCE: INSPECT CHECK DAMS AND CHANNELS FOR DAMAGE AFTER EACH RUNOFF EVENT.
ANTICIPATE SUBMERGENCE AND DEPOSITION ABOVE THE CHECK DAM AND EROSION FROM HIGH FLOWS
AROUND THE EDGES OF THE DAM. CORRECT ALL DAMAGE IMMEDIATELY. IF SIGNIFICANT EROSION
OCCURS BETWEEN DAMS, INSTALL A PROTECTIVE RIP RAP LINER IN THAT PORTION OF THE CHANNEL.
REMOVE SEDIMENT ACCUMULATED BEHIND THE DAMS AS NEEDED TO PREVENT DAMAGE TO CHANNEL
VEGETATION, ALLOW THE CHANNEL TO DRAIN THROUGH THE STONE CHECK DAM, AND PREVENT LARGE
FLOWS FROM CARRYING SEDIMENT OVER THE DAM. ADD STONES TO DAM AS NEEDED TO MAINTAIN
DESIGN HEIGHT AND CROSS SECTION.
