Plans*
Desiknation on the plans where the 7 and 14-day ground
stabil ation requirements of the NPDES permit apply
Desigkation on the plans where basins that comply with the
surface -withdrawal requirements of the NPDES permit are
located
n Building Wastes Handling
• No pa t or liquid wastes in stream or storm drains
• Dedicated areas for demolition, construction and other
wastes located 50' from storm drains and streams unless
so ble alternatives are available.
E hen- aterial stockpiles located 50' from storm
ains unl ss no reasonable alternatives available.
ete aterials must be controlled to avoid contact
with surfac 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.
Major Elements of DRJonstruction 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

* "Extensions of time may be approved by the permitting authority
based on weather or other site -specific conditions that make compliance
impracticable." (Section IL3(2)(b))
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. GLOBAL
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.
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
1 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
• htiqitements are the same as in previous permit.
• Thy pe mit allows reduction from the 20 acre minimum if
t �1r ctor of DWQ determines that other BMPs provide
e i� t protection.
