PART I PERMIT COVERAGE
1. During the period beginning on the effective date of the permit and lasting until expiration, the
City of New Bern is authorized to discharge stormwater from the municipal separate storm sewer
system (MS4) to receiving waters of the State within the Neuse River Basin. Such discharges
will be controlled, limited and monitored in accordance with 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 including, for each of the measures identified in the permit, a narrative description of the
program, a table that identifies each best management practice (BMP), 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 managed in accordance with the terms and conditions of
this permit. Any 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.
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 owned
and operated by the permittee within the jurisdictional area of the permittee. The permit applies
to 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 shall be approved by the Division of Energy, Mineral, and Land Resources, 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.
6. 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.
7. The permittee shall implement its approved Stormwater 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. The specific requirements of section 402(p)(3)(B) of the Clean Water Act require that
the permittee effectively prohibit non-stormwater discharges to the permittee's MS4 and that
controls and management measures are implemented by the permittee to reduce the discharge of
pollutants from the municipal storm sewer system to the maximum extent practicable.
8. The purpose of the Stormwater Plan is the means by which the permittee will describe how it is in
compliance with the permit. Compliance with the six minimum measures in 40 CFR § 122.34(b)

SECTION J: ELECTRONIC REPORTING OF REPORTS [G.S. 143-215.1(b)]
Starting on December 21, 2020, Federal regulations require electronic submittal of all reports and specify
that, if a state does not establish a system to receive such submittals, then permittees must submit reports
electronically to the Environmental Protection Agency (EPA). This special condition supplements or
supersedes the following sections within Part IV of this permit (Reporting and Record Keeping
Requirements):
Section 1. Records
Section 2. Recording Results
Section 3. Annual Reporting
Section 8. Report Submittals
1. Reporting Requirements [Supersedes Part IV Paragraph 3 (a) through (c)]
Beginning in December 21, 2020, the permittee shall electronically report the following compliance
monitoring data and reports:
Separate Storm Sewer System (MS4) Program Reports (See Part III 2., Program Assessment)
The permittee may seek an electronic reporting waiver from the Division (see “How to Request a
Waiver from Electronic Reporting” paragraph 3 below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(l)(9), the permittee must identify the initial recipient at the time of
each electronic submission. The permittee should use U.S. 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 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.gov/compliance/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 the 15th of the
month following the completed reporting period. The permittee must sign and certify all electronic
submissions in accordance with the requirements of Part IV, Paragraph 8(c), of this permit.
PERMIT NO. NCS000585
Part II Page 18 of 18
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the
Division. Requests for temporary electronic reporting waivers must be submitted in writing to the
Division for written approval at least sixty (60) days prior to the date the facility would be required
under this permit to begin submitting monitoring data and reports. The duration of a temporary
waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports
shall be submitted electronically unless the permittee re-applies for and is granted a new temporary
electronic reporting waiver by the Division. Approved electronic reporting waivers are not
transferrable. Only permittees with an approved reporting waiver request may submit monitoring
data and reports on paper to the Division for the period that the approved reporting waiver request is
effective.
Information on the application for a temporary electronic reporting waiver are found on the following
web page:

(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

16. Non-stormwater Discharge Categories
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).
17. 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
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.
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 stormwater control than the previous development.
22. 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.
23. Storm Sewer System
Is a conveyance or system of conveyances which are designed or used to collect or convey
stormwater runoff that is not part of a combined sewer system or treatment works. This can
include, but is not limited to, streets, catch basins, curbs, gutters, ditches, man-made channels or
storm drains that convey stormwater runoff.
24. 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
activities defined in 40 CFR 122.26(b)(14). The term does not include discharges from facilities
or activities excluded from the NPDES program.
25. Stormwater Management Program (SWMP)
The term Stormwater Management Program (SWMP) refers to the stormwater management
program that is required by the Phase I and Phase II regulations to be developed by MS4
permittees.
26. 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.

27. Stormwater Runoff
The flow of water which results from precipitation and which occurs immediately following
rainfall or as a result of snowmelt.
28. 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.
