Sanitary Sewer Overflow- February 2024
Collection System Permit No. WQCS00026
Monroe Collection System
Union County
Dear Mr. Pitner,
This letter is in response to the NC Department of Environmental Quality(NCDEQ)Notice of
Violation, the letter dated March 12th, 2024 and received by City of Monroe Water Resources on March
14th, 2024.
NCDEQ identified the following Sanitary Sewer Overflow (SSO) on February 21st, 2024 as ineffectively
managing, and maintaining the collections system. In response the City of Monroe is providing the
following evidence that the SSO was unintentional and that the overflow was beyond the reasonable
control of our operations and that compliance with our collections system permit remains our utmost
responsibility.
Incident#202400506 occurred on an off-street easement in the rear a residential area off of Curtis Street.
This specific line had been cleaned on January 25, 2023, the area had previously been smoke tested back
on February 28, 2017. There was debris noted in the manhole, as noted in the 5-day BIMS report. It was
noted when staff was on-site that there was a significant amount of rags, wipes, FOG (Fats, Oil, and
Grease) found in the line, which is an all residential area on an off-street easement. The lids in the area
are to be water tight. It was noted that the SSO was coming out around the pick holes in the cover. The
spill was called in by a home owner off of West Park Drive, a Water Resources crew responded to the
call immediately.
Upon identifying the area and checking an elevated upstream manhole that was surcharged it was
determined, where the blockage was located. When cleaning the line to rid the blockage, it was
determined that the spill was a result of rags, wipes, and grease which had created a blockage on the 8"

HDPE gravity sewer main. A City of Monroe Water Resources representative was stationed onsite
during the duration of the spill to monitor any changes and when the spill mitigated. Once the spill was
stopped the affected area was treated with lime as stated in the BIMS report. We also notified the City of
Monroe Storm Water Division of the spill as indicated in the BIM's report.
The City of Monroe Water Resources Maintenance Staff are currently working in the area on smoke
testing and is distributing educational information to the public using our social media page with the
help of the City of Monroe Public Information Officer. The goal is to increase public awareness to help
eliminate the spills in the area. While cleaning the line we found debris and have now cleaned the entire
area of the line. The Maintenance Superintendent, as well as the Pre-Treatment Coordinator, visited the
site and determined that the area is all residential and the debris is coming from a home in the area. After
the smoke testing is completed, crews will be using CCTV in the area in the coming months as part of a
basin project.
The SSO was not within reasonable control of the permittee; the SSO could not have been prevented by
the exercise of reasonable control, such as proper management,preventive maintenance. The permittee
followed all City of Monroe Sanitary Sewer Overflow Response Plan(SSOP)procedures.
The City of Monroe meets and exceeds the 10% cleaning goal each year with various methods including
pipe bursting, CIPP,basin cleaning, CCTV and cleaning. The City of Monroe has staff available 24
hours a day 7 days per week with anticipated response time of less the 45 minutes to respond to any
given call. This helps us to reduce the impact and duration of sanitary sewer spills. In addition, contracts
are utilized with construction companies for emergency situations.
The City of Monroe respectively requesting that no civil penalties be applied to the above SSO that
occurred during the month of February 2024, due to the above factors being satisfied and evidence
showing that the overflow was not expected to occur.
If you have any questions or require further information, please contact me at 704-282-4610 or via email

Sincerely,
Chuck Derrick
