PART I PERMIT COVERAGE

A. During the period beginning on the effective da te of the per mit and lasting until expiration, the
City of Char lotte is authorized to discharge stor mwater from the municipal separate stor m sewer
system (MS4) to receiving waters of the State within the Catawba and Yadkin-Pee Dee River
Basins. Such discharge will be controlled, limited and monitored in accordance with this permit
progra m for the five-year ter m of the stor mwa ter per mit.

B. All discharges authorized herein shall be managed in accordance with the ter ms and conditions of
this permit. Any other point source discharge to surface waters of the state is prohibited unless it
is an allowable non-stor mwater discharge or is covered by another per mit, authorization, or
approval.

C. This permit does not relieve the per mitt ee 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 stor mwater fro m the MS4 that are
corporate limits of the per mittee.

purpose of the Stor mwater Plan is to establish the means by which the per mittee will achieve
compliance with the provisions of the Clean Water Act and this permit. The specific requirements
of Section 402(p)(3)(B)(iii) of the Clean Water Act require the per mittee, to the extent allowable
under State or local law, to effectively prohibit non-stor m water discharges into the stor m sewers
and controls to reduce pollutant discharges to the maximum extent practicable (MEP).

H. Compliance with this permit constitutes compliance with the requirements of the Clean Water
Act and 15 N.C. Administrative Code 02H .0126, .0150 - .0153 (NPDES) and 15A N.C.
Admi nistrative Code 02H .1000 to reduce the discharge of pollutants from the MS4 to the ME P.

J. Unless otherwise stated, full compliance with the requirements of the permit is expected upon the
effective date of the permit. Should per mit conditions change for any reason, due to annexations
or otherwise, the per mittee must notify DEQ and modify the Stor mwa ter Plan within the time
fra me provided with the notice.

SECTION K: ELECTRONIC REPORTING OF R EPORTS [General Statute 143-215.1(b)]
The fina l NPDES Electronic Reporting Rule was adopt ed and became effective on December 21,
2015. These federal regulations require electronic sub mittal of all MS4 program reports by no
later than Dece mber 21, 2020, and specify that, if a state does not establish a system to receive
such sub mittals, then per mittees must sub mit monitoring data and reports electronically to the
U.S. Environmental Protection Agency (EPA).
2. This special condition supplements or supersedes the following sections within Part IV of this
permit (Reporting and Record Keeping Requirements):

• Paragraph A. Records
• Paragraph B. Annual Reporting
• Paragraph G. Report Sub mittals

3. Starting on December 21, 2020, the permittee sha ll electronically report the following compliance

Initial recipient of electronic NPDES infor mation from NPDES -regulated facilities (initial
recipient) means the entity (EPA or the state, tribe, or territory authorized by EPA to imple ment
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 anticipa tes tha t EP A will be the initial
recipient for electronic MS4 Program Reports.

EPA plans to establish a website tha t will also link to the appropriate electronic reporting tool for
each type of electronic sub missi on 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:

5. 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 permitt ee must first sub mit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waiver s must be sub mitted in writing

31. Total Maximum Daily Load (TMDL)

A TMDL is a calculation of the maximum amount of a pollutant tha t a waterbody can receive and

TMDL is a detailed water quality a ssessment tha t provides the s cientific foundation for an
implementation plan. The implementation plan outline s the steps necessary to reduce pollutant
loads in a certain body of water to restore and maintain wa ter quality standards in all seasons. The
Clean Water Act, Section 303, establishes the water quality standards and TMDL programs.
