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 [e-mail].
Sincerely,

Sanitary Sewer Overflows — February 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 # Date Location
202300271 2/12/2023 5419 Silver Creek Drive, Waxhaw, NC 28173
The SSO listed in this section was due to a heavy rain event causing flooding that overwhelmed
our system. Heavy rain fell across much of North Carolina on Sunday February 12, 2023. The
rainfall measured at this location was 1.54 inches within 12 hours. We are reviewing our Master
Plan data to identify any sources of I&I in this basin.
Incident -# 202300291, 202300292, and 202300293
Date- 2/13/2023
Addresses;
2230 Wesley Chapel Rd, Indian Trail, NC, 28079
7001 Sedgewick Rd, Indian Trail, NC, 28079

The SSO's listed in this section was due to a force main break and, once discovered. Once the
sewer force main leak was discovered, our Poplin Road Pump Station was shut down. As a
result, overflows occurred at the above locations and the break location overflowed several
times during the line shut down and repair.
Incident # Date Location
202300334 2/21/2023 3385 Rainbow Drive, Waxhaw, NC 28173
The SSO listed in this section was due to grease accumulating in the line causing a backup. We
took immediate action by jetting the main to clear the blockage. Education material was
distributed upstream of the area and routine cleaning will be increased.
Incident # Date Location
202300348 2/22/2023 2840 Gray Fox Rd, Monroe, NC, 28110
The SSO listed in this section was due to a valve failure. We took immediate action by
conducting a pump and haul while a new valve was installed.
Union County Water also has an aggressive Capital Improvement Program. 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

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
