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 #202003076, located at 2531 Buena Vista Road 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 11 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 Brushy Creek to flood well outside
of its banks.
On November 12 at 8:45am, a Utilities Field Operations crew happened to drive by 2531 Buena
Vista Road and discovered an SSO due to heavy rain and flooding caused by the tropical storm.
The spill was less than 1,000 gallons and was resolved in 40 minutes at 9:25am. The crew used
their combo jet/vac truck to clean and sanitize the area following protocol.
