PART I PERMIT COVERAGE
During the period beginning on the effective date of the permit and lasting until expiration, the
City of Wilmington is authorized to discharge stormwater from the municipal separate storm
sewer system (MS4) to receiving waters of the State within the Cape Fear River Basin. Such
discharge will be controlled, limited and monitored in accordance with the penmittee's
Comprehensive Stormwater Management Program, herein referred to as the Stormwater Plan.
The Stormwater Plan must detail the permittee's Stormwater management program for the five-
year term of the stormwater permit including, for each of the measure identified in the permit, a
narrative description of the program, a table that identifies each best management practice (BMP)
used, the frequency of the BMP, the measurable goals for each BMP, the implementation
schedule, funding and the responsible person or position for implementation..
2. All discharges authorized herein shall be adequately managed in accordance with the terms and
conditions of this permit. Any other point source discharge to surface waters of the state is
prohibited unless it is an allowable non-stornwater discharge or is covered by another permit,
authorization, or approval.
3. 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.
4. This permit covers activities associated with the discharge of stormwater from the MS4 within
the jurisdictional area of the pernittce 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 permittee, 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.
The Division may deny or revoke coverage under this permit for separate entities and require
independent permit coverage as deemed necessary. In addition, the pennittee may petition the
Division to revoke or deny coverage under this pen -nit for specific entities.
6. Under the authority of Section 402(p) of the Clean Water Act and implementing regulations 40
CFR Part 122, 123 and 124, North Carolina General Statutes 143-215.1 and Session Law 2004-
163 and in accordance with the approved Stormwater Plan, all provisions contained and
referenced in the Stormwater Plan are enforceable parts of this pen -nit. The permittee will
develop and implement its approved Stonmwater Plan in accordance with Section 402(p)(3)(B) of
the Clean Water Act, provisions outlined by the Director, and the provisions of this permit.
7. The permit requires the development and proper implementation of the Stormwater Management
Plan. The purpose of the Stormwater Management Plan is to reduce the discharge of pollutants
from the MS4 to the maximum extent practicable, to protect water quality, and to satisfy the
applicable water quality requirements of the Clean Water Act. Implementation of best
management practices consistent with the provisions of the Stormwater Management Plan
constitutes compliance with the standard of reducing pollutants to the maximum extent
practicable. Successive iterations of the Stormwater Management Plan and other components of
this permit will be driven by the objective of assuring that discharges do not cause or contribute
to the violation of water quality standards, through the expansion and tailoring of management
measures within the scope of the Stormwater Management Plan,
Part I Page 1 of 2

PERMIT NO. NCS000406
8. The permit authorizes the point source discharge of stormwater runoff from the MS4. In
addition, discharges of non-stormwater are also authorized through the MS4 of the permittee if
such discharges are:
(a) Permitted by, and in compliance with, another NPDES discharge permit including
discharges of process and non -process wastewater, and stormwater associated with
industrial activity; or
(b) Determined to be incidental non-stormwater flows that do not significantly impact water
quality and may include:

PART II FINAL LIMITATIONS AND CONTROLS FOR PERMITTED DISCHARGES
SECTION A: PROGRAM IMPLEMENTATION
The pennittee 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:
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
pennittee 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.
The pennittee'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 pennittee 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 implement'appropriate education, training, outreach, and public involvement
. programs to support the objectives of this stormwater discharge permit and the Stormwater Plan.
6. The pennittee will implement a program to reduce pollution from construction site runoff as
described in the Stormwater Plan and in accordance with this permit.
7. The permittee will implement a post -construction site runoff control program to regulate new
development and redevelopment by requiring structural and non-structural best management
practices to protect water quality, to reduce pollutant loading, and to minimize post -development
impacts. This program will include provisions for long-term operation and maintenance of
BMPs.
The permittee will evaluate municipal operations and develop and implement an appropriate
program for municipal activities and ongoing operation and maintenance of municipal facilities
to reduce the potential for Stormwater pollution.

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 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.

(b) In order to fulfill the post -construction minimum measure program requirement, a
permittee, delegated program, or regulated entity may use the Department's model
ordinance, design its own post -construction practices based on the Department's
guidance on scientific and engineering standards for best management practices (BMPs),
incorporate the post -construction model practices described herein, or develop its own
comprehensive watershed plan that is determined by the Department to meet the
post -construction stormwater management measure:
(c) Pennittecs must require stormwater controls for a project that disturbs one acre or more
of land, including a project that disturbs less than one acre of land that is part of a larger
common plan of development or sale. The stormwater controls shall be appropriate to the
project's level of density as follows:
(1) Post -construction model practices for low -density projects. —A project that is
located within one-half mile of and draining to Shellfish Resource Waters is a
low -density project if it contains no more than twelve percent (12%) built -upon
area. A project that is not located within one-half mile of Shellfish Resource
Waters is a low -density project if it contains no more than twenty-four percent
(24%) built -upon area or no more than two dwelling units per acre. Low -density
projects must use vegetated conveyances to the maximum extent practicable to
transport stormwater runoff from the project. On -site stormwater treatment
devices such as infiltration areas, bioretention areas, and level spreaders may
also be used as added controls for stormwater runoff. A project with an overall
density at or below the low -density thresholds, but containing areas with a
density greater than the overall project density, may be considered low density as
long as the project meets or exceeds the post -construction model practices for
low -density projects and locates the higher density in upland areas and away
from surface waters and drainageways to the maximum extent practicable.
(2) Post -construction model practices for high -density projects. — A project that is
located within one-half mile of and draining to Shellfish Resource Waters is a
high -density project if it contains more than twelve percent (12%) built -upon
area. A project that is not located within one-half mile of Shellfish Resource
Waters is a high -density project if it contains more than twenty-four percent
Page I of 15

PERMIT NO. NCS000406
(24%) built -upon area or more than two dwelling units per acre. High -density
projects must use structural stormwater management systems that will control
and treat control and treat runoff from the first one and one-half inches of rain.
In addition, projects that are located within one-half mile and draining to
Shellfish Resource Waters must control and treat the difference in the
stormwater runoff from the predevelopment and post -development conditions for
the one-year, 24- hour storm. The structural stormwater management system
must also meet the following design standards:
A. Draw down the treatment volume no faster than 48 hours, but no slower
than 120 hours.
B. Discharge the storage volume at a rate equal to or less than the
predevelopment discharge rate for the one-year, 24-hour storm.
C. Remove an eighty-five percent (85%) average annual amount of Total
Suspended Solids.
D. Meet the General Engineering Design Criteria set out in 15A NCAC
0214 .1008(c) or a locally approved stormwater management manual.
E. Wet detention ponds designed in accordance with the requirements of
Paragraph (3)(d) may be used for projects draining to Class SA waters.
(d) For areas draining to Class SA waters, permittecs, delegated programs, and regulated
entities must:
(1) Use BMPs that result in the highest degree of fecal colifonn die -off and control
to the maximum extent practicable sources of fecal coliform while still
incorporating the stormwater controls required by the project's density level.
(2) Implement.a program to control the sources of fecal coliform to the maximum
extent practicable, including a pet waste management component, which may be
achieved by revising an existing litter ordinance, and an on -site domestic
wastewater treatment systems component to ensure proper operation and
maintenance of such systems, which may be coordinated with local county
health departments.
(3) Prohibit new points of stormwater discharge to Class SA waters and prohibit
both increases in the volume of stormwater flow through conveyances and
increases in capacity of conveyances in existing stormwater conveyance systems
that drain to Class SA waters. Any modification or redesign of a stormwater
conveyance system within the contributing drainage basin must not increase the
net amount or rate of stormwater discharge through existing outfalls to Class SA
waters. Diffuse flow of stormwater at a nonerosive velocity to a vegetated buffer
or other natural area capable of providing effective infiltration of the runoff from
the one-year, 24-hour storm shall not be considered a direct point of stormwater
discharge. Consideration shall be given to soil type, slope, vegetation, and
existing hydrology when evaluating infiltration effectiveness.
(e) For BMPs that require a separation from the seasonal high-water table, the separation
shall be provided by at least 12 inches of naturally occurring soil above the seasonal
high-water table.

For the purposes of this permit, industrial activities shall mean all industrial activities as defined
in 40 CFR 122.26.
14. Major municipal separate storm sewer outfall (or "major outfall")
Major municipal separate storm sewer outfall (or "major outfall") means a municipal separate
storm sewer outfall that discharges from a single pipe with an inside diameter of 36 inches or
more or its equivalent (discharge from a single conveyance other than circular pipe which is
associated with a drainage area of more than 50 acres); or for municipal separate storm sewers
that receive storm water from lands zoned for industrial activity (based on comprehensive zoning
plans or the equivalent), an outfall that discharges from a single pipe with an inside diameter of
12 inches or more or from its equivalent (discharge from other than a circular pipe associated
with a drainage area of 2 acres or more).
15. Municipal Separate Storm Sewer System (MS4)
Pursuant to 40 CFR 122.26(b)(8) means a conveyance or system of conveyances (including roads
with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade
channels, or storm drains):
(a) Owned or operated by the United States, a State, city, town, county, district, association,
or other public body (created by or pursuant to State law) having jurisdiction over
disposal of sewage, industrial wastes, stormwater, or other wastes, including special
districts under State law such as a sewer district, flood control district or drainage
district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or
Part V1I1 Page 2 of 4

PERMIT NO. NCS000406
a designated and approved management agency under Section 208 of the Clean Water
Act (CWA) that discharges to waters of the United States or waters of the State.
(b) . Designed or used for collecting or conveying stormwater;
(c) Which is not a combined sewer; and
(d) Which is not part of a Publicly Owned Treatment Works (POTW) as defined in 40 CFR
122.2
lb. Non-stormwater Discharge Categories
The following are categories of non-stormwater discharges that the-pernnittee 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).
17. Non-structural $MP
Non-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.
18. Outfall
Outfall means a point source as defined by 40 CFR 122.2 at the point where a municipal separate
storm sewer discharges to waters of the United States and does not include open conveyances
connecting two municipal separate storm sewers, or pipes, tunnels or other conveyances which
connect segments of the same stream or other waters of the United States and are used to convey
waters of the United States.
19. Permittee
The owner or operator issued this permit.

PERMIT NO. NCS000406
20. 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 is or may be
discharged to waters of the state.
21, Redevelopment
Means any rebuilding activity unless that rebuilding activity;
(a) Results in no net increase in built -upon area, and
(b) Provides equal or greater stortnwater control than the previous development.
22. Stormwater Runoff
The flow of water which results from precipitation and which occurs immediately following
rainfall or as a result of snowmelt.
23. Total Maximum Daily Load (TMDL)
A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive
and still meet water quality standards, and an allocation of that amount to the pollutant's sources.
A TMDL is a detailed water quality assessment that provides the scientific foundation for an .
implementation plan. The implementation plan outlines the steps necessary to reduce pollutant
loads in a certain body of water to restore and maintain water quality standards in all seasons.
The Clean Water Act, Section 303, establishes the water quality standards and TMDL programs.
24. Toxic Pollutant
Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.
