of the state is prohibited unless it is an allowable non-stormwater discharge or is covered
by another permit, authorization, or approval.
3. This permit does not relieve the permitter from responsibility for compliance with any
other applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or
decree.
4. This permit covers activities associated with the discharge of stormwater from the MS4
within the jurisdictional area of the permitter, as described in the approved local
Stormwater Plan to control potential pollution from the MS4. The permit applies to
current and future jurisdictional areas of the permitter, as well as areas that seek coverage
under this permit through inter -local or other similar agreements with permittee.
Agreements for coverage under this permit must be approved by the Division of Water
Quality, herein referred to as the Division.
5. The Division may deny or revoke coverage under this permit for separate entities and
require independent permit coverage as deemed necessary. In addition, the permittee may
petition the Division to revoke or deny coverage under this permit for specific entities.

SECTION A: PROGRAM IMPLEMENTATION
The permittee will implement, manage and oversee all provisions of its Stormwater Plan to
reduce pollutants discharged from the MS4. This includes, but is not limited to, the following
areas:
1. The permittee will develop and maintain adequate legal mechanism, such as regulations,
ordinances, policies and procedures to implement all provisions of the Stormwater Plan.
The permittee will keep the Division advised of the status of development of appropriate
ordinances and legal authorities and will pursue these authorities in accordance with the
schedule outlined in the Stormwater Plan.
2. The permittee's Stormwater Plan will be implemented and managed such that the
discharge of pollutants from the MS4 is reduced to the maximum extent practicable. It is
anticipated that in order to meet this provision, implementation of the Stormwater Plan
will occur with emphasis given to priority areas and to management measures and
programs that are most effective and efficient at varying stages of the plan's
implementation.
3. The permittee will implement the components of the Stormwater Plan to prohibit, to the
maximum extent practicable, illicit connections, spills and illegal dumping into the MS4.
4. The permittee will implement provisions of the Stormwater Plan as appropriate to
monitor and assess the performance of the various management measures that are a part
of the Stormwater Plan. This will include the provisions of this permit.
5. The permittee will maintain adequate funding and staffing to implement and manage the
provisions of the Stormwater Plan.

Program. The following additional requirements apply.
(a) Within two years after receiving the Division's notice that the permittee is subject
to a TMDL, the permittee shall establish a TMDL Water Quality Recovery
Program and shall identify the locations of all currently known MS4 outfalls
within its jurisdictional area with the potential of discharging the pollutant(s) of
concern: to the impaired segments, to their tributaries, and to segments and
tributaries within the watershed contributing to the impaired segments. The
permittee shall also develop a schedule to discover and locate all other MS4
outfalls within its jurisdictional area that may be discharging the pollutant(s) of
concern: to the impaired stream segments, to their tributaries, and to segments and
tributaries within the watershed contributing to the impaired segments.
(b) Within two years after receiving the Division's notice that the permittee is subject
to a TMDL, the permittee shall develop a monitoring plan for each pollutant of
concern. The monitoring plan shall include the sample location by verbal
description and latitude and longitude coordinates, sample type, frequency, any
seasonal considerations, and a monitoring implementation schedule for each
pollutant of concern. Where appropriate, the permittee may reduce the monitoring
burden by proposing to monitor outfalls that the Division would consider
substantially similar to other outfalls. The permittee may also propose in -stream
monitoring where it would complement the overall monitoring plan. The
monitoring plan shall be adjusted as additional outfalls are identified in
accordance with the schedule required in (a) above and as accumulating data may
suggest.
(c) The permittee shall include the location of all currently known MS4 outfalls with
the potential of discharging the pollutant(s) of concern, the schedule for
discovering and locating currently unknown MS4 outfalls with the potential of
discharging the pollutant(s) of concern, and the monitoring plan, (all as required
in (a) and (b) above, and all part of the TMDL Water Quality Recovery Program)
in the first Stormwater Management Plan annual report due no earlier than two
years after the Division's initial notification of the applicability of a TMDL.
(d) The next and each subsequent Stormwater Management Plan annual report shall
include an assessment of the available data for each pollutant of concern, and an
assessment of the effectiveness of the BMPs employed, to determine what, if any,
additional BMP measures may be necessary to return the impaired segments to
compliance with state water quality standards. The permittee shall implement
Part II Page 2 of 13

PERMIT NO. NCS000500
appropriate BMPs to control the pollutant(s) of concern to the maximum extent
practicable. Implementation of the appropriate best management practices
constitutes compliance with the standard of reducing pollutants to the maximum
extent practicable.

Dear Mr. Mitchell:
Enclosed for your review and comment is the draft Phase 2 NPDES Stormwater Permit for the
Town of Ayden. Following an appropriate public notice and comment period, we anticipate this
permit will become effective in the 4th quarter of 2005.
After a review of your permit application materials, I found that it was well written and sufficient
to issue the permit. Please carefully inspect the draft permit and update your Stormwater
Management Program Plan to reflect any changes that may be necessary to comply with the
permit. In particular, please update Section 7.5 of your plan to address the requirements for post -
construction stormwater management in new development and redevelopment.
We believe that this draft permit will provide your community with the flexibility vital for your
community, while at the same time safeguarding and protecting our natural environment for
future generations of North Carolinians.
We look forward to receiving your comments on this draft permit and continuing to work

The following are categorieslof non!kormwater discharges that the permittee must
address if it identifies them,as,"significant contributors of pollutants to the storm sewer
system: water line flushing, landscape irrigation, diverted stream flows, rising
groundwater, uncontaminated groundwater infiltration, (as defined in 40 CFR
35.2005(20)], uncontaminated pumped groundwater, discharges from potable water
sources, foundation drains, air conditioning condensation, irrigation water, springs, water
from crawl space pumps, footing drains, lawn watering, individual residential car
washing, flows from riparian habitats and wetlands, dechlorinated swimming pool
discharges, and street wash water (discharges or flows from fire fighting activities are
excluded from the definition of illicit discharge and only need to be addressed where they
are identified as significant sources of pollutants to waters of the United States).
Non-structural .BMP
Nan -structural BMPs are preventive actions that involve management and source controls
such as: (1) Policies and ordinances that provide requirements and standards to direct
growth to identified areas, protect sensitive areas such as wetlands and riparian areas,
maintain and/or increase open space, provide buffers along sensitive water bodies,
minimize impervious surfaces, and/or minimize disturbance of soils and vegetation; (2)
policies or ordinances that encourage infill development in higher density urban areas,
and areas with existing storm sewer infrastructure; (3) education programs for developers
and the public about minimizing water quality impacts; (4) other measures such as
minimizing the percentage of impervious area after development, use of measures to
minimize directly connected impervious areas, and source control measures often thought
of as good housekeeping, preventive maintenance and spill prevention.
