PART I PERMIT COVERAGE
A. 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, Smith Creek, Burnt Mill Creek, Greenfield Lake,
Barnards Creek, and Motts Creek, within the Cape Fear River Basin and Howe Creek, Bradley
Creek, Hewletts Creek, Intracoastal Waterway, and Whiskey Creek, within the White Oak River
Basin. Such discharge will be controlled, limited and monitored in accordance with this permit
and the permittee's Stormwater Quality Management Program, herein referred to as the
Stormwater Plan. The Stormwater Plan shall detail the permittee's stormwater management
program for the five-year term of the stormwater permit, for each 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.
B. All discharges authorized herein shall be 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-stormwater discharge or is covered by another permit, authorization, or
approval.
C. 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.
D. This permit covers activities associated with the discharge of stormwater from the MS4 within the
corporate limits of the permittee. The permit applies to the corporate limits 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 shall be approved by the Division of
Energy, Mineral and Land Resources, herein referred to as the Division.
E. 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.
F. All provisions contained and referenced in the Stormwater Plan along with all provisions and
approved modifications of the Stormwater Plan are incorporated by reference and are enforceable
parts of this permit.
G. The permit requires the proper implementation of the Stormwater Plan. To the extent allowable
under State and local law, the permittee must develop and implement a Stormwater Plan in
accordance with Section 402(p)(3)(B)(iii) of the Clean Water Act. The purpose of the
Stormwater Plan is to describe the means that the permittee will use to comply with the permit
and with the provisions of the Clean Water Act. Compliance with the six minimum measures in
40 CFR § 122.34(b) and with the requirements of this permit constitute compliance with the
Clean Water Act to reduce the discharge of pollutants from the MS4 to the maximum extent
practicable (MEP), 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 Plan constitutes compliance with the standard of reducing
pollutants to the MEP.

PART II FINAL LIMITATIONS AND CONTROLS FOR PERMITTED DISCHARGES
SECTION A: PROGRAM IMPLEMENTATION
The permittee will implement, manage and oversee all provisions of its Stormwater Plan to control to the
maximum extent practical the discharge of pollutants from its municipal storm sewer system associated
with stormwater runoff and illicit discharges, including spills and illegal dumping. The overall program
implementation however, will be subject to, at a minimum, either 1) an annual review by the Division to
determine implementation status and progression toward meeting the pollutant control intent of the
Stormwater Plan, i.e., a compliance audit, or 2) a voluntary assessment process that has been approved by
the Division and is at least as stringent as the annual review described herein. Voluntary assessments,
such as the MS6 Program established by the Stormwater Association of North Carolina (SWANC), NC
APWA and their partners may be conducted by the local government, another local government with and
NPDES MS4 permit, or an independent third party and shall be reviewed and approved by the Division.
This includes, but is not limited to, the following areas:
The permittee will maintain adequate funding and staffing to implement and manage the
provisions of the Stormwater Plan and meet all requirements of this permit. The Stormwater Plan
shall identify a specific position(s) responsible for the overall coordination, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented and
position(s) assignments provided.
2. The permittee will implement provisions of the Stormwater Plan and evaluate the performance
and effectiveness of the program components at least annually. Results will be used by the
permittee to modify the program components as necessary to accomplish the intent of the
Stormwater Program. If the permittee implements the six minimum control measures and the
discharges are determined to cause or contribute to non -attainment of an applicable water quality
standard, to address the non -attainment, the permittee shall expand or better tailor its BMPs
within the scope of the six minimum control measures.
3. The permittee is required to keep the Stormwater Plan up to date. Where the permittee
determines, or is informed by the Division that modifications are needed to address any
procedural, protocol, or programmatic change, such changes shall be made as soon as practicable,
but not later than 90 days, unless an extension is approved by the Division. When it notifies the
Division of proposed modifications, the permittee will include an explanation and justification of
the proposed changes. The permittee shall provide at least 30 days for the Division to provide
feedback on proposed modifications. Major modifications to the Stormwater Plan shall not take
effect until approved by the Division.
4. The permittee is required to make available its Stormwater Plan to the Division upon request. The
permittee is required to keep an up-to-date version of its Stormwater Plan available to the
Division and the public online. At a minimum, the online materials shall include ordinances, or
other regulatory mechanisms, or a list identifying the ordinances, or other regulatory mechanisms,
providing the legal authority necessary to implement and enforce the requirements of the permit.

identified in the approved TMDL to the maximum extent practicable and to the extent
authorized by law.
C. If subject to an approved TMDL with a NPDES MS4 regulated WLA assigned to the
permittee, the permittee will be considered in compliance with the TMDL if the permittee
complies with the conditions of this permit, including developing and implementing
appropriate BMPs within the six minimum measures to address the permittee's MS4s
NPDES regulated WLA to the maximum extent practicable (MEP). While improved
water quality is the expected outcome, the permittee's obligation is to implement BMP's
designed to address the NPDES regulated waste load allocation assigned to the permittee
to the maximum extent practicable (MEP). The permittee is not responsible for attaining
water quality standards (WQS). The Division expects attaining WQS will only be
achieved through reduction from all point and nonpoint source contributors identified in
the approved TMDL.

The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
4. Electronic Submissions [Supplements Part IV]
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the
time of each electronic submission. The permittee should use EPA's website resources to identify
the initial recipient for electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities (initial
recipient) means the entity (EPA or the state, tribe, or territory authorized by EPA to implement
the NPDES program) that is the designated entity for receiving electronic NPDES data [see 40
CFR 127.2(b)]. As of permit issuance, The NC DEQ anticipates that EPA will be the initial
recipient for electronic MS4 Program Reports.
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Currently, Electronic Reporting
Rule information is found at: https://www.epa. ov�pliance/final-national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above. The permittee must electronically submit MS4 annual program reports no later than
October 31St following the completed reporting period. The permittee must sign and certify all

14. MEP
MEP is defined in the Federal Register (U.S. EPA, 1999, p. 68754). This document says that
"Compliance with the conditions of the general permit and the series of steps associated with
identification and implementation of the minimum control measures will satisfy the MEP
standard." Minimum control measures are defined in the Federal Register as (1) public education
and outreach, (2) public participation/involvement, (3) illicit discharge detection and elimination,
(4) construction site runoff control, (5) post -construction runoff control, and (6) pollution
prevention/good housekeeping.

The following are categories of non-stormwater discharges that the permittee shall 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).
18. Non-structural BMP
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

PERMIT NO. NCS000406
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.
19. 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.
20. Permittee
The owner or operator issued this permit.
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 is or may be
discharged to waters of the state.
22. Redevelopment
"Redevelopment" means any land -disturbing activity that does not result in a net increase in
built -upon area and that provides greater or equal stormwater control than the previous
development.
23. Representative Storm Event
A storm event that measures greater than 0.1 inches of rainfall and that is preceded by at
least 72 hours in which no storm event measuring greater than 0.1 inches has occurred. A
single storm event may contain up to 10 consecutive hours of no precipitation. For
example, if it rains for 2 hours without producing any collectable discharge, and then
stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.
24. Six Minimum Measures. or Six Minimum Control Measures
As defined in 40 CFR § 122.34(b). They are Public Education and Outreach, Public
Involvement/Participation, Illicit Discharge Detection and Elimination, Construction Site Runoff
Controls, Post -Construction Runoff Controls, and Pollution Prevention and Good Housekeeping
for Municipal Operations.

Sensitive Waters are waters a) with a TMDL developed and approved, or established by EPA, b)
Included in the most recent NC DEQ Section 303(d) list approved by EPA, and/or that pursuant
to NCDEQ Water Classifications & Standards, waters that are classified as either Outstanding
Resource Waters (ORW), Trout Waters (Natural (TN)), or, Shellfish Waters (SA).
26. Splash pad (sprU ground)
An outdoor play area with sprinklers, fountains, nozzles, and other devices or structures that

include, but is not limited to, streets, catch basins, curbs, gutters, ditches, man-made channels or
storm drains that convey stormwater runoff.
28. Stormwater Associated with Industrial Activity
The discharge from any point source which is used for collecting and conveying stormwater and
which is directly related to manufacturing, processing or raw material storage areas at an
industrial site. Facilities considered to be engaged in "industrial activities" include those

The term Stormwater Management Program (SWMP) refers to the stormwater management
program that is required by the Phase I and Phase 11 regulations to be developed by MS4
permittees.
31. Stormwater Plan
The Stormwater Plan is the written plan that is used to describe the various control measures
and activities the permittee will undertake to implement the stormwater management
program. The Stormwater Plan is a consolidation of all of the permittee's relevant ordinances
or other regulatory requirements, the description of all programs and procedures (including
standard forms to be used for reports and inspections) that will be implemented and enforced
to comply with the permit and to document the selection, design, and installation of all
stormwater control measures.

32. Stormwater Runoff
The flow of water which results from precipitation and which occurs immediately following
rainfall or as a result of snowmelt.
33. 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.
