SUBJECT: Notice of Violation NOV-2019-DV-0314
Town of Clayton Collection System Permit Number WQCS00110
Dear Mr. Smith:
The following information is provided in response to your letter of August 13, 2019, that was received August 19, 2019, related
to the Town of Clayton's actions to correct and prevent future SSO occurrences:
Incident Number 201901008
This SSO was caused by a contractor working in an active construction zone adjacent to an existing sewer force main. The
contractor inadvertently struck a force main with an excavator while trying to remove wet soil from their excavation. The creek
that was affected was blocked to capture the release and return it to the system. The area adjacent to the release was abated
and restored. The contractor replaced the damaged section of pipe and the Town's Engineering Department inspected the
repairs.
Please contact me if any additional information is required at this time. Thank you for the attention provided to our response.
