SUBJECT: NOTICE OF VIOLATION &INTENT TO ISSUE CIVIL PENALTY
Tracking No.: NOV-2023-DV-0109
Sanitary Sewer Overflows - January 2023
Collection System Permit No. WQCS00054
Union County Collection System
Union County
Dear Mr. Matthews:
A review has been conducted of the self-reported Sanitary Sewer Overflows (SSO's) 5-Day Report/s submitted by
Union County. The Division's Mooresville Regional Office concludes that the Union County violated Permit Condition
I (2) of Permit No. WQCS00054 by failing to effectively manage, maintain, and operate their collection system so
that there is no SSO (Sanitary Sewer Overflow) to the land or surface waters and the SSO constituted making an
outlet to waters of the State for purposes of G.S. 143-215.1(a)(1), for which a permit is required by G.S.
143-215.1.
The Mooresville Regional Office is providing the Union County an opportunity to provide evidence and justification
as to why the Union County should not be assessed a civil penalty for the violation(s) that are summarized below:

This Notice of Violation / Notice of Intent to Enforce (NOV/NOI) is being issued for the noted violation. Pursuant
to G.S. 143-215.6A, a civil penalty of not more than twenty-five thousand dollars ($25,000.00) may be assessed
against any person who violates or fails to act in accordance with the terms, conditions, or requirements of any
permit issued pursuant to G.S. 143-215.1.
This office requests that you respond to this Notice, in writing, within 10 business days of its
receipt. In your response, you should address the causes of non-compliance, remedial actions, and all other
actions taken to prevent the recurrence of similar situations. The response to this correspondence will be
considered in this process. Enforcement decisions will also be based on volume spilled, volume reaching surface
waters, duration and gravity, impacts to public health, fish kills or recreational area closures. Other factors
considered in determining the amount of the civil penalty are the violator's history of non-compliance, the cost of
rectifying the damage, whether the spill was intentional and whether money was saved by non-compliance.
If you have any questions, please do not hesitate to contact Joanna Harbison with the Water Quality Section in
the Mooresville Regional Office at 704-663-1699 or via email at
Sincerely,
—DocuSigned by:

Sanitary Sewer Overflows — January 2023
Collection System Permit — WQCS00054
Union County Water
Dear Mr. Pitner:
Union County Water has received the NOV referenced above for collection system overflows.
Explanations of the overflows were on the BIMS Overflow Reporting Forms submitted by Union
County Water to the NCDEQ. However, we have added a few additional facts in the
explanations below.
Incident -# 202300176, 202300177, 202300179, and 202300180
Date- 1/30/2023-1/31/2023
Addresses;
1111 Austin Chaney Road, Wingate, NC 28174
1470 NC-205, Marshville, NC 28103
4610 Monroe Ansonville Road, Wingate, NC 28174
The SSO's listed in this section was due to a contractor boring through a sewer force main.
After the force main was hit, several of our Eastside Pump Stations were shut down. The result
caused MH# 2700, MH# 2701, and MH# 2646 to spill during the line repair effort. The SSO
which occurred at the intersection of Monroe Ansonville Road and Austin Chaney Road was at
the location of the hit force main. The other two SSOs occurred as a result of the repair effort
downstream since the repair lasted through the night into the following day. Since the line was
properly located, the contractor responsible has been billed $41,214 to date.

Incident # Date Location
202300181 1/31/2023 8299 Kensington Drive, Waxhaw, NC 28173
The SSO listed in this section was due to debris causing a backup—debris wedged inside the
gravity sewer. We took immediate action by jetting the main to clear the blockage.
Union County Water also has a Capital Improvement Program which includes a number of
projects directed towards improving the wastewater collection system and avoiding SSOs. The
projects include:
• Crooked Creek Basin Improvements - $1M (based on $200K annual funding)
Waxhaw Interceptor under construction — $6,150,000
• Wastewater Pump Station Improvements - $3,500,000
Crooked Creek Interceptor Improvements- $16,000.000
12 Mile Creek I & I Abatement: $2.3M planned for FY24 — FY28 ($400k each for FY24 &
FY25; $500k each for FY26, 27 & 28)
Septic Tank Assessment/Replacement Program Northside: $2.56M currently available
for gray water system replacement & $7.8M total planned with annual allocations from
FY24 — FY28
Septic Tank Assessment/Replacement Waxhaw: $1.2M currently being used in FY23
with $2.9M planned for FY24; project complete after FY24
Wastewater R&R Program: $10.2M planned FY24 — FY28 (annual allocations ranging
from $1.9M to $2.2M)
• Collection System SSES: $2.4M ($200k FY24; $900k FY25; $200k FY27; $1.1M FY28)
Union County Water continues to invest funds into SSES work, capital improvements,
maintenance, FOG, and operations to improve the wastewater collection system. If further
information or details regarding the projects listed above are needed, please feel free to contact
Greg Morgan, Superintendent/ORC, at 704-289-3288 or myself at 704-296-4215.
Thank you for your consideration on this issue.
