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. 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.
Most of these construction activities are also subject to the Sedimentation Pollution Control Act of 1973
(SPCA), which 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 for a construction activity shall take the following steps in
the following order:
1. Develop an E&SC Plan. This plan shall adhere to the requirements of this permit and the SPCA.
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 the appropriate state or state delegated local entity
(hereafter known as the E&SC Plan authority).
3. Electronically submit a Notice of Intent (NOI) to the Division with proof of approval of the E&SC
Plan uploaded. The Division shall then issue a Certificate of Coverage under the NCG01
Construction General Permit within five business days if all provisions are adequately met.
4. Commence the construction activity only after receipt of the Certificate of Coverage.
S. Abide by the conditions of both the NCG01 permit and the E&SC Plan until completion of the
construction activity.
6. After the construction is complete and the site is permanently stabilized, contact the E&SC Plan
authority that approved the E&SC plan to close out the project.
7. Electronically submit a request to rescind coverage under the NCG01 permit to the Division with
the close-out documentation uploaded. The Division shall then rescind the Certificate of
Coverage within five business days if all provisions are adequately met.
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 0213.0200). 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
should be made at least 180 days prior to the time the permit is needed unless waived by the Director
(see Part IV Section B of this permit).

16. Landfill
A disposal facility or part of a disposal facility where waste is placed in or on land and which is not a
land treatment facility, a surface impoundment, an injection well, a hazardous waste long-term
storage facility or a surface storage facility.
17. Normal Business Hours
These are generally considered to be between the hours of 6 a.m. and 6 p.m., or when workers are
normally present on the construction site. Weekends, state and federal holidays are not considered
normal business hours unless construction activities are taking place on the site during those times.
18. Notice of Intent
The state application form which, when submitted to the Division, officially indicates the facility's
notice of intent to seek coverage under a general permit.
19. Permanent Stabilization
When all soil disturbing activity is completed and exposed soils have been stabilized with a
vegetative cover with a density of at least 80% or covered with a structural stabilization method.
Permanent perennial vegetation may include the use of sod, shrubs and ground cover plants mixed
with mulching, aggregate or other landscaping techniques. Structural methods include concrete,
asphalt, retaining wall or other stabilization techniques.
20. Permittee
The person, firm or organizational entity that signed as the financially responsible party on the
Erosion and Sedimentation Control Plan.

Permit No. NCG010000
21. Point Source Discharge of Stormwater
Any discernible, confined and discrete conveyance including, but not specifically limited to, any pipe,
ditch, channel, tunnel, conduit, well, or discrete fissure from which stormwater associated with
industrial activity is or may be discharged to waters of the state.
22. Secondary Containment
Spill containment for the contents of the single largest tank within the containment structure plus
sufficient freeboard to allow for the 25 -year, 24-hour storm event.
23. Section 313 Water Priority Chemical
