Subject: NOTICE OF DEFICIENCY (NOD-2022-PC-0101)
Town of Mooresville
NPDES MS4 Permit No. NCS000540
Iredell County
Dear Mr. Hermann:
On June 8, 2022, staff from the North Carolina Department of Environmental Quality (DEQ) conducted a compliance
audit of subject National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System
(MS4) Permit. The audit identified minor deficiencies with the specific components of the MS4 permit that were
reviewed, as provided in the attached DEQ MS4 Permit Compliance Audit Report. This report lists and describes the
deficiencies with certain components of the MS4 permit, which constitutes a violation of the Clean Water Act and is
grounds for enforcement action.
In accordance with Part VI of the permit and DEQ policy, a new 5-year MS4 permit will be issued in response to the
audit. As such, the permittee is required to complete the following actions:
1. Respond in writing within thirty (30) calendar days from the date of receipt of this notice to acknowledge
these requirements and the intent to comply.
2. Self -evaluate the permit components that were not reviewed by DEQ for compliance and submit the results
within one hundred twenty (120) calendar days from the date of receipt of this letter. The Part II of the MS4
Phase II Audit Template on the DEQ stormwater web site can be used for this purpose. The specific
sections that should be self -audited include:
a. Section E: Construction Site Runoff Controls;
b. Section F: Post -Construction Site Runoff Controls;
c. Section H: Total Maximum Daily Loads.
3. Develop a Stormwater Management Plan (SWMP) which details specific actions, measurable goals, and
implementation timelines for the stormwater management program over the new 5-year permit term. The
SWMP must be documented utilizing the DEQ Phase II MS4 SWMP Template. The permittee shall submit
the SWMP to DEQ for review and comment within one hundred twenty (120) calendar days from the date of
receipt of this letter.

5. Respond to comments on the Draft Final SWMP and submit a signed Final SWMP for DEQ approval and

Attention: Jeanette Powell
1612 Mail Service Center

If the MS4 fails to meet the aforementioned requirements and/or submits a significantly noncompliant Draft SWMP,
DEQ may proceed with enforcement. As is stated in Part V, Section A.1(c) of the permit:
Under state law, a daily civil penalty of not more than twenty-five thousand dollars ($25, 000) per violation
may be assessed against any person who violates or fails to act in accordance with the terms, conditions, or
requirements of a permit [North Carolina General Statute 143-215.6A]. Please note that compliance with
the requirements of this NOD and/or issuance of civil or criminal penalties levied by DEQ does not preclude
the EPA from carrying out its own enforcement case against the permittee.
Thank you for your attention to this matter. Should you have any questions, please contact Jesse McDonnell at (704)
677-0568 or Jesse. [e-mail], or the MS4 Program Coordinator at [e-mail].
