Stormwater Report DEC 2 8 2023
Dear Tamera: Winston-Salem
Enclosed is the Stormwater Report for the 4th Quarter of 2023. Regional Office
Wieland is in Tier 3 for exceeding the copper benchmark value in all 5 Outfalls and in Tier 3 for exceeding
the Zinc benchmark value in Outfall 003 and 004. Attached is a copy of the Tier 3 investigation report.
Wieland is in Tier 2 for exceeding the pH benchmark value in Outfalls 001-004.
The Tier III plan that we initiated has reduced the copper levels in the outfalls.
WCP was not able to begin monthly sampling due to inadequate rainfall.
If you have any questions, please feel free to call me at [phone].
Sincerely,

interval dots not apply if the permittee is able to document that a shorter interval is representative for
1 local storm events during the sampling period,and the permittee obtains approval from the local DEi41LR
Regional Office.

Stormwater Management Inspection Tier III Violation
Conducted 12/14/23
I. Benchmark Value Limit Violations-Outfall 001
A. Copper Total—0.367 mg/L Limit-0.010 mg/L Tier III
B. pH-7.0 Limit-6-9 Tier II
11. Observations
A. Residual dust on the roof and in the roof drains from Billet Cast operation that was discontinued
on October 20,2020.
B. Copper dust settling on the roof and dock area from the Direct Casting operation.
C. Direct Casting maintenance on contaminated equipment being done outside the building.
D. Forklift and equipment traffic spilling copper slag on the dock while loading trucks.
E. Hoppers with copper chips stored outside in the weather.
F. Copper slag on the dock.
III. Recommended Corrective Actions.
A. Monitor the Direct Cast operation in order to determine whether or not dust control is needed for
the copper furnaces.
B. Installation of a conveyor system in order to charge the copper furnaces more efficiently without
the need to open the hood which will greatly increase the containment of dust.
C. Move furnace equipment maintenance in a covered area or inside the plant.(Implemented
Tier II)
D. Sweep the dock areas daily and after trucks are loaded.(Implemented Tier II)
E. Continue to monitor the roof drains to see if the copper concentrations remain the same or
reducing as time goes on.

Direct Casting Furnaces.
XVII. Recommended Corrective Actions
A. Continue to monitor. The outfall is located next to the wooded area away from the plant.The
influent is primarily drainage from the wooded areas which is located about 150 feet from the
plant.
