To Whom It May Concern:
This letter is written in response to the Notice of Violation, Tracking number NOV-2019-
DV-0083 for the Town of Mount Pleasant NC. This SSO occurred at 1232 Summer
Street lift station.
The cause of the spill was a power failure caused by mechanical type failure. The
incoming line feeding the switch gear to the station burned in two. This station is a Delta
Y feed with no neutral, meaning that the station could not be powered off of the
generator with the incoming line burned in two due to possible damage to the pump
motors and switch gear.
Duke Energy was notified as soon as crews were on site but took approximately one
hour to respond. This delayed the repair to the station due to one leg feeding in was still
live.
This station is currently in the design phase for upgrade/replacement due to being at
capacity limit for development. Remediation of the site was completed using debris
collection and using lime to cover the affected area. No wastewater entered surface
water with this SSO.
Sincerely,
T. Justin Stallings
