Permit No. NCGO10000
PART I — NCG01 PERMIT COVERAGE
This permit applies to all owners or operators of stormwater discharges associated with construction
activities such as clearing, grading, and excavation, that result in the disturbance of a land area greater
than or equal to one acre, or that are part of a common plan of development of that size or greater that
are also subject to the North Carolina Sedimentation Pollution Control Act of 1973 (SPCA). This
permit may also be issued to stormwater discharges from like activities deemed by the Division of
Energy, Mineral, and Land Resources (DEMLR) to be similar to these operations in process or
stormwater discharges. This permit shall not apply to land -disturbing activities that are covered under
the NCG020000 (Mining Activities) permit or the NCG120000 (Landfills) permit.
The SPCA requires that the persons engaged in subject construction activities develop and adhere to an
Erosion and Sedimentation Control (E&SC) Plan. The Sedimentation Control Commission and DEMLR
have created and adopted a North Carolina Erosion and Sediment Control Planning and Design Manual
describing recommended sedimentation control techniques for construction activities.
A person seeking coverage under this permit shall take the following steps in the following order:
1. Develop an E&SC plan that adheres to the SWPPP requirements of this permit, the SPCA and 15A
NCAC 04B .0101-.0132. The North Carolina Erosion and Sediment Control Planning and Design
Manual shall be used as guidance in meeting the applicable requirements.
2. Obtain approval of the E&SC plan by either DEMLR or the appropriate state delegated local
entity (hereafter known as the "E&SC plan authority").
3. Submit an electronic Notice of Intent (e-N01) to DEMLR with documentation of the E&SC plan
approval scanned and uploaded. The a-NOI is available at httl2s://deg.nc.gov/NCGO1. In
addition, pay the general annual permit fee provided for in § 143-215.3D. DEMLR shall email
the COC within three business days (or 24 hours for a project being reviewed under DEMLR's
Express review program) after the submittal of a complete and correct a-NOI and the receipt of
the general permitting fee.
4. Commence the construction activity after receipt of the COC.
S. Abide by the conditions of both the NCGO1 permit and the E&SC plan until completion of the
construction activity and establishment of permanent ground stabilization.
6. Contact the E&SC plan authority after construction is complete and the site is permanently
stabilized, contact the E&SC plan authority for the final/close out inspection of the E&SC plan.
7. Submit an electronic Notice of Termination (e-NOT) with a scan of the close-out inspection
report uploaded. The a -NOT is available athttl2s://deq.nc.gov/NCGO1. DEMLR shall email
confirmation of the close-out of the CDC within three business days after the submittal of a
complete and correct a -NOT.
The discharges allowed by this General Permit shall not cause or contribute to violations of North
Carolina Water Quality Standards for surface waters and wetlands (15A NCAC 02B .0200). Discharges
allowed by this permit must meet all applicable water quality certification or permit requirements as
outlined in 15A NCAC 02H .0500 and 02H .1300. This permit does not relieve the permittee from
responsibility for compliance with any other applicable federal, state, or local law, rule, standard,
ordinance, order, judgment, or decree. This General Permit does not cover any other point source
discharge to surface waters of the state, nor does it cover activities or discharges that are covered by an
individual NPDES permit.
Any owner or operator of a subject construction activity not wishing to be covered or limited by this
General Permit may apply for an individual NPDES permit in accordance with NPDES procedures in 15A
NCAC 02H .0100, stating the reasons supporting the request. Any application for an individual permit

Permit No.NCGO10000
9. Lower Portions of the Site
Portions of a site that are lower in elevation than adjacent discharge locations and are not
expected to discharge during construction may be exempt from the temporary ground cover
requirements if identified on the approved E&SC plan or added by the E&SC plan authority.
SECTION C: ADDITIONAL DESIGN AND CONSTRUCTION STANDARDS IN HIGH
QUALITY WATER (HQW) ZONES
1. Extent of the HQW Zone
HQW Zones are those areas in the 20 Coastal Counties that are within 575 feet of High Quality
Waters and for the remainder of the state, areas that are within one mile of and drain to HQWs.
2. Disturbed Area Limits in HQW Zones
Disturbed areas in HQW zones shall be limited at any time to a maximum total area within the
boundaries of the tract of 20 acres. Only the portion of the construction activity within a HQW zone
shall be subject to the 20-acre limit. Larger disturbed areas may be allowed with the written
approval of the Director upon providing adequate engineering justification with a specific
construction sequence that addresses phasing, limited exposure, weekly submitted self -inspection
reports and/or more conservative design than the 25-year storm. The Director may also include
other conditions as necessary based on specific site conditions.
3. Additional Sediment Basin Requirements in HQW Zones
Sediment basins that discharge to HQW Zones shall be designed and constructed to meet the
following criteria unless the permittee demonstrates to the E&SC plan authority that meeting each
of the basin design conditions below would result in design or operational hardships. Alternative
control measures, such as quicker application of ground cover or use of sediment flocculants, shall
be allowed as a substitute on a case -by -case basis if it can be shown that use of the alternate
practices is expected to result in an equal or better sediment discharge reduction from the site.
(a) Use a surface withdrawal mechanism except when the basin drainage area is less than 1.0 acre.
(b) Have a minimum of 1800 cubic feet per of storage area per acre of disturbed area.
(c) Have a minimum surface area of 325 square feet per cfs for the peak flow from the 25-year
storm.
(d) Have a minimum dewatering time of 48 hours.
(e) Incorporate three baffles unless the basin is less than 20 feet in length, in which case two baffles
are sufficient.
4. Open Channels in HQW Zones
Newly constructed open channels in HQW zones shall be designed and constructed with side slopes
no steeper than two horizontal to one vertical if a vegetative cover is used for stabilization unless soil
conditions permit a steeper slope or where the slopes are stabilized by using mechanical devices,
structural devices or other acceptable ditch liners. The angle for side slopes shall be sufficient to
restrain accelerated erosion.

Permit No. NCGO10000
SECTION D: CONSTRUCTION ACTIVITY BUFFERS
The requirements in Section D below shall not apply to a land -disturbing activity in connection with the
construction of facilities to be located on, over, or under a lake or natural watercourse (NCGS 113A-57).
1. Buffers in Non -Trout Waters
Unless wider buffers are required per NC rules or statutes, the width of the buffer shall be sufficient
to confine visible sedimentation to the 25 percent of the strip closest to the land -disturbing activity.
The width of a buffer adjacent to a non -trout water shall be measured from the edge of the water to
the nearest edge of the disturbed area.
Recommended buffer widths to achieve this standard are shown in Table 2 below.

2. Buffers in Trout Waters
Unless wider buffers are required per NC rules or statutes, the minimum width for an undisturbed
buffer adjacent to trout waters shall be 25 feet. The width of a buffer adjacent to a trout water shall
be measured horizontally from the top of bank to the nearest edge of the land -disturbing activity.
However, the Sedimentation Control Commission may approve plans that include land -disturbing
activity along trout waters when the duration of said disturbance would be temporary and the
extent of said disturbance would be minimal. (NCGS 113A-57(1)).
SECTION E: GROUND STABILIZATION
1. Ground Stabilization Timelines
Ground stabilization shall be achieved on any area of a site where land disturbing activities have
ceased within the timeframes listed in Table 3 below. It is recommended to stabilize the ground
more quickly if practicable. Extensions of time may be approved by the E&SC plan authority based
on weather or other site -specific conditions that make compliance impracticable. Portions of a site
that are lower in elevation and not expected to discharge during construction may be exempt from
the temporary ground cover requirements if identified on the E&SC plan and approved by the E&SC
plan authority.

Insecticide, Fungicide, and Rodenticide Act and label restrictions.
5. Concrete Materials
Concrete materials onsite, including excess concrete, shall be controlled and managed to avoid
contact with surface waters, wetlands or buffers. No concrete or cement slurry shall be discharged
from the site. (Note that discharges from onsite concrete plants require coverage under a separate
NPDES permit - NCG140000.) Any hardened concrete residue will be disposed of, or recycled on
site, in accordance with local and state solid waste regulations.
6. Earthen Material Stock Piles
Earthen material stock piles shall be located at least 50 feet away from storm drain inlets and
surface waters unless no other alternatives are reasonably available.
SECTION G: OPERATION AND MAINTENANCE
1. Modifications to the E&SC Plan
Modifications to the approved E&SC plan that require changes to the E&SC measure designs, the
drainage areas, or the disturbed areas draining to E&SC measures shall be approved by the
E&SC plan authority. Deviations from the approved E&SC plan, or approved revised E&SC plan,
shall constitute a violation of this permit unless the deviation is to correct an emergency
situation where sediment is being discharged off the site. The E&SC plan authority may allow
deviations from the E&SC plan on a case -by -case basis if the deviations are minor adjustments to
Page 9 of 26

Permit NO.NCG010000
address minor deficiencies. A minor adjustment shall be the addition of E&SC measures (e.g.,
silt fence, inlet protection, check dams, rolled erosion control practices, etc.), or the relocation of
E&SC measures that would improve the overall stormwater management and sediment control
onsite. Minor adjustments shall be noted on the approved E&SC plan and maintained at the job
site.
2. Operation and Maintenance
The permittee shall install and maintain all temporary and permanent E&SC measures as required
by this permit and the approved E&SC plan.
3. Corrective Actions
If self -inspections required by this permit identify a need for maintenance of control measures,
modifications or additions to control measures, or corrective actions to control sediment or other
pollutants, these actions shall be performed as soon as possible considering adverse weather and
site conditions.
4. Draw Down of Sediment Basins for Maintenance or Close Out
Sediment basins and traps that receive runoff from drainage areas of one acre or more shall use
outlet structures that withdraw water from the surface when these devices need to be drawn
down for maintenance or close out unless this is infeasible. The circumstances in which it is not
feasible to withdraw water from the surface shall be rare (for example, times with extended cold
weather). Non -surface withdrawals from sediment basins shall be allowed only when all of the
following criteria have been met:
(a) The E&SC Plan authority has been provided with documentation of the non -surface withdrawal
