Dear :asin•;er:
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
202200187 2/4/2022 390 Chestnut Parkway
The SSO listed in this section was due to a Force Main change over for the Forest Park Lift
Station. On startup of the new Force Main, the discharge overwhelmed the receiving manhole
causing the spill. When observed, startup ceased and adjustments made to the design with
construction modifications set for early April.
Union County Water also has an aggressive Capital Improvement Program throughout the next
5 years. The projects include:
*- Crooked Creek Basin Improvements - $47,000,000

Union County Water's current CIP projects are also ongoing with projects including:
➢ Forest Park PS Replacement & Interceptor Improvements —Phase 1- $3,900,000
➢ Crooked Creek l&I Study & Remediation - $633,000

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 CCWRF Improvements, as well as, the CIP projects listed
above are required, please feel free to contact Greg Morgan, Superintendent/ORC, at 704-289-
