Dear Mr. Snider,
This letter responds to the Notice of Violation and Recommendation for Enforcement Letter
dated September 17, 2020 received by the City of Greensboro. The address where the violation
occurred and the amount spilled is shown below:
1. 1618 Maplewood Lane. 2700 Gallons
The sanitary sewer release at 1618 Maplewood Lane was due to a pipe failure at this address.
Upon notification of the sanitary sewer spill, we dispatched a construction crew to the site and
made a temporary repair. Once we remediated the sanitary sewer overflow, we scheduled a
permeant repair that took place on July 23`d. Due to the age and poor condition of the pipe, we
replaced approximately 14' of steel and clay pipe with Mek-Lok ductile iron pipe to ensure we
had the strength and longevity we needed to prevent this high priority line from failing in the
future. This pipe section is up for rehabilitation within the next two years as well. Due to the line
being an aerial line, we had to approach our temporary repair with extra caution to ensure our
employees' safety, which contributed to the longer than expected event duration.
Remediation efforts include opening fire hydrants to flush the affected area.
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
