Re: Sanitary Sewer Overflow Civil Penalties Incident #202003159
Dear Mr. Snider:
This letter serves as the official response from Winston-Salem/Forsyth County Utilities to the
North Carolina Department of Environmental Quality, Division of Water Resources Notice of
Intent to Enforce Civil Penalty for the November 12, 2020 sanitary sewer overflow (SSO),
Incident #202003159, located at 2536 LaDeara Crest Lane in Winston-Salem. The incident was a
result of inflow and infiltration due to severe natural conditions during Tropical Storm Eta.
Normal precipitation at Winston-Salem Airport for the month of November is 3.11 inches. In
November 2020, more than 6.65 inches fell and 5.37 inches of that was during the November
11-12 storm event. Rain began falling at 2:00am on November it and did not subside until
7:00pm on November 12. Gage height information for Abbotts Creek (Lexington) and the
Yadkin River (Yadkin College) indicate that both exceeded flood stage with a rise on the order of
18-20 feet during the rainfall period. This heavy rain caused Boulevard Branch to flood outside
of its banks.
On November 12 at 11:05am, first responders arrived at 2536 LaDeara Crest Lane and
discovered an SSO behind the buildings, in front of the fence line. It was evident that the SSO
was a result of heavy rain and flash flooding caused by the tropical storm. The spill was slightly
over 1,000 gallons, it lasted less than an hour and was resolved by 12:00pm. The crew
immediately used their combo jet/vac truck to clean and sanitize the area following protocol.
