Cover Sheet for NCG010000 Revised August 2, 2011
What is this permit?
This is your General Stormwater Permit for Con-
struction Activities, developed to meet federal Na-
tional Pollutant Discharge Elimination System
(NPDES) requirements. It is separate from your Ero-
sion and Sedimentation Control (E&SC) Plan, which
has been a North Carolina requirement for over 35
years.
Federal regulations adopted by the U.S. Environ-
mental Protection Agency (EPA) and North Carolina
Division of Water Quality (DWQ) require an NPDES
permit for your project. The EPA has delegated
DWQ authority to administer the NPDES program in
North Carolina. Two divisions of the Department of
Environment and Natural Resources are responsi-
ble for different parts of the federal permitting re-
quirements.
The E&SC plan approved by the Division of Land
Resources (or a delegated local program) contains
the core erosion control requirements for your pro-
ject. The NPDES General Permit issued by DWQ
contains additional requirements related to a
broader range of water quality issues. These per-
mits are related, but separate. Both contain con-
ditions your project site must meet.
What does this permit require me to do?
You should read and become fa-
miliar with the provisions of this
permit. Below is a list of the ma-
jor requirements, with indications
where those differ from the previ-
ous Construction General Permit.
EROSION AND
SEDIMENT CONTROL PLAN
You must implement the Erosion
and Sedimentation Control Plan
approved for your project by the
Division of Land Resources or by
an approved local program.
Adherence to that E&SC Plan is
an enforceable component of the
Stormwater Permit.
Your E&SC plan will identify
Are there new requirements
in this permit?
This General Permit reflects changes made in the
federal regulations effective February 1, 2010, that
regulate discharges from construction sites. The
federal regulations resulted from litigation decisions
that mandated construction activities over a certain
size must contain additional specifications to reduce
the amount of wastes and sediment loading that
reach the nation's waters.
The Division of Water Quality and the Division of
Land Resources established the Construction Gen-
eral Permit Technical Advisory Group (CTAG) to
guide the development of this NPDES permit. A
draft permit was available for public review in May
2011, and the final permit became effective on Au-
gust 3, 2011.
The most notable change in the new permit is a re-
quirement that ground stabilization, such as wheat
straw application, be applied within 14 days from the
last land -disturbing activity. For steep slopes, that
area must be stabilized within 7 days. Please see
page 2 of this document for details.
areas where the more stringent
7 and 14 day ground stabiliza-
tion requirements apply. See
"New Ground Stabilization Re-
quirements" on page 2.
MONITORING & INSPECTIONS
► You must keep a rain gauge
on site.
► Dedicated demolition and
other waste areas and earthen
material stockpiles must be lo-
cated at least 50' from storm
drains or streams unless no alter-
native is feasible (new require-
ment).
► You must inspect all E&SC
measures at least once a week
and within 24 hours after any
storm event greater than a half
inch (during a 24-hour period).
You must take immediate cor-
rective action for any device
failure.
► You must inspect all outlets
where stormwater runoff leaves
your site and evaluate the effect
on nearby streams or wetlands.
Corrective action must be taken if
sediment is deposited off site or
into a stream or wetland, or
causes a visible increase in tur-
bidity (cloudiness) of any water -
body.
► You must keep records of
these inspections and any correc-

tive actions taken.
OPERATION & MAINTENANCE
You must provide the operation
and maintenance necessary to
maintain optimal performance of
stormwater controls. This means
take corrective action if erosion
and sediment control facilities are
not operating properly! Operation
and maintenance includes, but is
not limited to:
♦ Regularly cleaning out sedi-
mentation basins.
♦ Stabilizing eroded banks or
spillway structures.
♦ Repairing/clearing out inlets
and outlets.
♦ Repairing piping, seepage
and mechanical damage.
♦ Repairing silt fence damage.
REPORTING
Regular inspections are a chance
to check impacts to nearby wa-
ters. If you observe sediment
that has deposited in a stream
or wetland, you must notify the
Division of Water Quality re-
gional office within 24 hours and
provide written notice within 5
days (see # 3 on page 6 of the
General Permit). Please send a
copy of this correspondence to
the Division of Land Resources
(DLR).
NON-COMPLIANCE & FINES
Take compliance seriously! Pro-
jects that violate Stormwater Per-
mit conditions and/or have unau-
thorized water quality impacts are
subject to fines. Civil penalties
of up to $25,000.00 per day for
each violation may be as-
sessed.
Who inspects me for what?
DWQ coordinates with DLR's
Land Quality Section to ensure
compliance with state rules and
regulations governing construc-
tion activities. That means your
project is subject to enforcement
by both divisions. In general,
Land Quality staff will inspect
your site on a regular basis.
DWQ staff may also do inspec-
tions. The inspections may be
routine in nature, or, the result of
public complaints.
Do I need to submit a Notice
of Intent to have coverage
under this permit?
No. Once your E&SC Plan is ap-
proved, your site is automatically
covered under this permit. You
do not need to submit a Notice of
Intent for a Certificate of Cover-
age.
