Notification of Discharge of Untreated Wastewater
General Statue 143-215.1C requires that the owner or operator of any wastewater collection or
treatment works to issue a press release when an untreated wastewater discharge of 1,000 gallons
or more reaches surface waters.
In accordance with that regulation, the following news release has been prepared and issued to
media in the affected county.
Lincoln County Public Utilities had a discharge of untreated wastewater on June 30, 2022 of an
estimated 10,000 gallons from a manhole at the intersection of NC Hwy 73 and NC Hwy 16. It is
estimated that 6,000 gallons of untreated wastewater was discharged into Forney Creek Tributary 1A
for approximately seven hours. The discharge was reported to the Public Utilities Division at 2:12PM
and normal flow restored in the sewer line at 9:11PM. Grease and rags were removed and the gravity
main was jetted to prevent further discharge.
The Division of Water Resources was notified on June 30, 2022 and is reviewing the matter. For
more information contact Lincoln County Public Utilities at 704-736-8495.
