Sanitary Sewer Overflow-November 2023
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 December 12, 2023 and received by City of Monroe Water Resources on
December 15`h, 2023.
NCDEQ identified the following Sanitary Sewer Overflow (SSO) on November 27th, 2023 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 our
reasonable control of our operations and that compliance with our collections system permit remains our
utmost responsibility.
Incident#202301579 occurred on an off-street easement in near a commercial occupancy. This specific
line had been cleaned in 2017, the area had previously been smoke tested back on January 29 of 2019.
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, FOG(Fats, Oil, and Grease) found in the line which
exits the commercial area on an off-street easement area, the lids in the area are to be water tight and in
this case it was not. It was noted that the SSO was coming out around the ring and cover. The spill was
located by a Water Resources crew doing scheduled aerial crossing inspections.
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 grease and rags which had created a blockage on the 8"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 limed as stated in the BIMS report. We also notified the City of Monroe Storm Water Division
as well as the City of Monroe Water Treatment Plant of the spill as indicated in the BIM's report.
The City of Monroe Water Resources Engineering staff and Maintenance Staff are currently working on
a plan to help/take away spills in the area. We have since cleaned and CCTV'd the area and found debris
in the line and cleaned the entire area of the line as well. The Maintenance Superintendent as well as the
Pre-Treatment Coordinator visited the site and spoke to the business managers in the area and advised
them of the findings.
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 November 2023, 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 phone number 704-282-
4610 or via email at [e-mail]
Sincerely,
Chuck Derrick
