Dear Mr. Tysinger:
On July 12, 2004 the North Carolina General Assembly ratified Senate Bill 1210 (S 1210)
- Phase H Stormwater Management. The Governor signed the bill on August 2, 2004. This bill
addresses implementation of the federal NPDES Phase II stormwater program in North Carolina.
1n S 1210, the General Assembly provided a framework that will allow state and local
government agencies to begin implementing the program. The bill establishes minimum
stormwater management requirements for municipal storm sewer systems and also applies
stormwater controls to some developing areas around these municipalities.
Phase H Draft permits for local governments were publicly noticed the week of
November 1, 2004 for those communities identified in the 1990 U.S. Census. Your community's
permit has been noticed and copies of the draft permit are available at:
http://h2o.enr.state.nc.us/su/phase2_draft_per,mits.htm
We look forward to receiving your comments on this draft permit and continuing to work
together for the benefit of your community and North Carolina. All comments and request
should reference draft permit number NCS000437. Please provide your comments by Friday,
December 10, 2004, If you have any questions about this draft permit don't hesitate to contact

Comprehensive Stormwater Management Plan, herein referred to as the Stormwater Plan.
The Stormwater Plan includes components of the permittee's Phase II Municipal NPDES
Stormwater Permit Application, Comprehensive Stormwater Management Plan, and any
approved modifications.
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-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
within the jurisdictional area of the permittee and surrounding areas 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 the
permittee. Agreements for coverage under this permit must be approved by the Division
of Water Quality, herein referred to as the Division.

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.
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

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 duality and may include:
• water line flushing;
• landscape irrigation;
• diverted stream flows;
• rising groundwaters;
• uncontaminated groundwater infiltration;
• uncontaminated pumped groundwater;
• discharges from potable water sources;
• foundation drains;
• air conditioning condensate (commercial/residential);

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
reduce pollutants discharged from the MS4. This includes, but is not limited to, the following
areas:
The permittee will develop and maintain adequate legal authorities 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. Any
changes to the schedule must be approved by the Director.
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 appropriate components of the Stormwater Plan to
assure that, to the maximum extent practicable, illicit connections, spills, and illegal
dumping into the MS4 are prohibited.
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, but is not limited to, the provisions of this
permit and the applicable provisions of the permittee's Stormwater Plan.
The permittee will maintain adequate funding and staffing to implement and manage the
provisions of the Stormwater Plan.
6. 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.
7. The permittee will implement a program to reduce pollution from construction site runoff
as described in the permit application and in accordance with this permit.
8. The permittee will implement an appropriate 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.
Part 11 Page l of 12

NCS000437
9. 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.
10. Proposed permit modifications must be submitted to the Director for approval.
1 1. In the first Annual Report after issuance of this permit, or after establishment of TMDL
for a pollutant of concern in the permittee's storm water discharges during this permit
term, the permittee shall identify the impaired stream segment(s) and/or tributaries to
these impaired stream segments and the location of all known MS4 outfalls discharging a
pollutant of concern to these segments or occurring within one linear mile upstream of
these segments. The permittee shall also propose a monitoring plan (Plan) in the Annual
Report for each pollutant of concern. The Plan shall include the sample type, frequency,
any seasonal considerations, and an implementation schedule to monitor for each
Pollutant of concern. The Plan must also include a schedule for the permittee to confirm
the location of all MS4 outfalls discharging a pollutant of concern to the impaired stream
segments, or within one linear mile upstream of these segments. Subsequent Annual
Reports will include an assessment of the data for each pollutant of concern, and an
assessment of the effectiveness of the BMPs employed, to determine what, if any,
additional adaptive BMP measures may be necessary to contribute toward returning the
stream to compliance with State water quality standards. Following any review and
comment on the Plan by the Division, the permittee will incorporate any necessary
changes into the Plan. Review of this plan may result in comments from the Division that
will require changes to the plan.

the Stormwater Plan. This will include information on development and
implementation of all components of the Stormwater Plan for the past year and
schedules and plans for the year following each report.
(b) The permittee will adequately describe and justify any proposed changes to the
Stormwater Plan. This will include descriptions and supporting information for
the proposed changes and how these changes will impact the Stormwater Plan
(results, effectiveness, implementation schedule, etc.).
