Subject: NOTICE OF COMPLIANCE (NOC-2021-PC-0504)
County of Mecklenburg
NPDES MS4 Permit No. NCS000395
Mecklenburg County

Dear Mr. Canaan:

On April 26-30, 2021, staff from the North Carolina Department of Environmental Quality (DEQ)
conducted a compliance audit of the subject National Pollutant Discharge Elimination System (NPDES)
Municipal Separate Storm Sewer System (MS4) Permit, which included individual audits of Mecklenburg
County as the primary permittee and eight co-permittees; Charlotte-Mecklenburg Schools, Central
Piedmont Community College and the Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill,
Pineville. The Mecklenburg County audit did not identify any deficiencies with the specific components
of the MS4 permit that were reviewed, as documented in the attached DEQ MS4 Permit Compliance
Audit Report.

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, Mecklenburg County 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) Submit a Draft 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 county’s current Storm Water Quality Management Program
Plan is an acceptable SWMP alternative. The County shall submit the Draft SWMP to DEQ for
review and comment within one hundred twenty (120) calendar days from the date of receipt of
this notice.

(3) Submit an NPDES MS4 permit renewal application within one hundred twenty (120) calendar
days from the date of receipt of this notice. A new 5-year NPDES MS4 permit will be noticed
for public comment along with the submitted Draft SWMP.

(4) Respond to any public comments on the Draft SWMP and submit a Final SWMP for DEQ
approval and concurrent final permit issuance. The final DEQ-approved SWMP shall become
an enforceable component of the new NPDES MS4 permit.

(5) Notify DEQ immediately if it is determined that any of the eight current co-permittees will not
be included for coverage under the new permit, or if any new co-permittees will be added.

Required documentation shall be submitted via e-mail to [e-mail], or to:
