PERMITTED ACTIVITIES
Until this permit is modified or rescinded, permittees are authorized to construct, operate and
maintain impervious surfaces associated with the construction of a single family residence on a
single lot that is not part of a larger subdivision covered by an individual stormwater permit, and
which has met the following standards. All stormwater runoff from these projects shall be in
accordance with the attached schedules as follows.
Section A — Final Limitation and Controls for Stormwater Discharges
Section B — Schedule of Compliance
Section C — General Conditions
STANDARD CONDITIONS FOR GENERAL PERMITS
Any other discharge to surface waters of the state is prohibited unless covered by another permit,
authorization or approval.
This General Permit does not relieve the permittee from responsibility for compliance with any
other applicable federal, state, or local law, rule, standard, ordinance, order, judgement, or
decree.
GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the DWQ by the
filing of a Notice of Intent (NOI) and applicable fees. The NOI shall be submitted and a
certificate of coverage issued prior to the construction of any impervious surfaces or stormwater
runoff associated with the construction of a single family residence.
Any owner or developer not wishing to be covered or limited by this General Permit may make
application for an individual Stormwater Management Permit in accordance with the stormwater
rules, stating the reasons supporting the request. Any application for an individual permit should
be made at least 90 days prior to the time the permit is needed.
This General Permit does not cover activities or discharges covered by an individual permit. If
the proposed single family lot is located in a larger development project that is already covered
by an individual stormwater permit, the lot does not qualify for coverage under this general
permit. Any person conducting an activity covered by an individual permit but which could be
covered by this General Permit may request that the individual permit be rescinded and coverage
under this General Permit be provided.
The definition of any word or phrase in this General Permit shall be the same as given in Article
21, Chapter 143 of the General Statutes of North Carolina, as amended. Other words and phrases
used in the General Permit are defined in the stormwater rules.

DISCHARGES
During the period beginning on the effective date of the general permit, the Permittee is
authorized to construct, operate and maintain impervious surfaces associated with a single family
residence. Stormwater runoff from the permitted impervious surfaces shall be in accordance with
the following conditions:
A vegetated buffer/setback is required to be maintained between all impervious surfaces
and surface waters. Minimum required buffer/setback widths shall be provided as per
Table 1.
Table 1:
Location
COC Issue Date
Minimum Width
20 coastal counties
Sept. 1, 2003 - Oct 1, 2008
30'
20 coastal counties
After October 1, 2008
50' (30' — redevelo ment)
Phase II areas (non -coastal)
After July 1, 2006
30' (setback)
Non-Ph.I1 & non -coastal
After Sept. 1, 2003
30'
2. No built -upon area is allowed within the buffer or setback, except for water -dependent
structures such as bulkheads and boat ramps.
3. The proposed built -upon area (BUA) must be maintained at or below the applicable low
density level as per Table 2.
Table 2:

followed.
5. Roof drainage may not be piped directly to the receiving stream. All roof drains and
gutters must terminate before the edge of the buffer/setback.
6. The runoff from all impervious surfaces must be directed away from surface waters to the
extent practicable.
7. The amount of built -upon area must be minimized as much as possible. The use of
permeable pavement for the sidewalks and driveways is encouraged.

direct runoff beneath an impervious surface such as a road and that minimum amount
needed under driveways to provide access. Longer runs of pipe, or pipes that discharge
directly to surface waters, are prohibited.
