Dear Mr. Peterson:
On August 30,2023,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. 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.
3. Submit an NPDES MS4 permit application for whichever comes first:
a. At least one hundred eighty (180)days prior to permit expiration,or
b. Within thirty (30)days of receiving written DEQ concurrence that the submitted SWMP
documents a compliant stormwater management program and the MS4 should submit the
application including a signed Final Draft SWMP. A new 5-year NPDES MS4 permit will be
public noticed along with the Draft Final SWMP.
4. Respond to comments on the Draft Final SWMP and submit a signed Final SWMP for DEQ approval and
final permit issuance. The final DEQ-approved SWMP shall become an enforceable component of the
NPDES MS4 permit and an Annual Self-Assessment Template that corresponds to the approved SWMP
will be provided.

or requirements of a permit[North Carolina General Statute 143-215.6A]. Please note that compliance
