Dear Mr. Snider,

Regional Office
This letter is in response to the Notice of Violation and Recommendation for Enforcement Letter
dated July 14, 2020 received by the City of Greensboro. The address where the violation
occurred and the amount spilled is shown below:
1. 1619 Stanley Rd. 3000 Gallons
The sanitary sewer release at 1619 Stanley Rd. was due to debris accumulation in the sanitary
sewer from unblocking a sanitary sewer release at 1617 Stanley Rd. A combination jet truck was
dispatched to unstop the blockage and clean the line. Once the sanitary sewer overflow was
stopped, we thoroughly cleaned all lines in the area to ensure we could perform a CCTV
inspection of the line to see if further action will be needed to be taken to prevent future debris
accumulation. Upon inspection, we found the lines to be heavily corroded and restricted from
mineral deposits that contributed to the debris accumulation. Upon seeing these results, we
installed a manhole level detection alarm to assist in preventing future sanitary sewer releases,
and the lines are now under a $300,000 contract by a local utility contractor to be rehabbed to
avoid any further sanitary sewer discharges and we are currently at 75% compleation on this
project.
Remediation efforts include opening fire hydrants to flush the affected area, and lime was spread
as well to minimize the impact of the spill.
It is our duty to comply with the requirements of Collection System Permit Number WQCS00006
and G.S. 143-215.1(a)(1), and we will continue to address unforeseen circumstances as quickly
as they occur. If any additional information is required, please do contact me. We appreciate
your review and welcome your feedback.
Sincerely yours,
Robert Martin, Construction and Maintenance Supervisor
