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 NCG01 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: Atter the permanent cessation of construction activities, any areas with temporary

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:
Temporary Stabfl'nxtion
I PermanernStebilaation
• Temporary grass seed covered with straw or
• Permanent grass seed covered with straw or
other mulches and tackifiers
other mulches and tackifiers
• Hydroseeding
• Geotextile fabrics such as permanent soil
• Rolled erosion control products with or
reinforcement malting
without temporary grass seed
• Hydroseeding
• Appropriately applied straw or other mulch
• Shrubs or other permanent plantings covered
• Plastic sheeting
with mulch
• Uniform and evenly distributed ground cover
sufficient to restrain erosion
• Structural methods such as concrete, asphalt or
retaining walls
• Rolled erosion control products with grass seed
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 pending 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.

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
General Permit (NCG01) with emphasis placed on those elements that differ from the previous permit (expiration on August 2,
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
The major change in the Permit from the previous one is the shorter
1) Ground Stabilization* 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 advisorygroup,
CTAG, the Division and EPA -developed permit, now contains
requirements for ground cover within 14, and in some places, 7 days.

impracticable." (Section 11.13(2)(b))
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.

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.
S) 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.
