SUBJECT: Compliance Evaluation Inspection
Elizabeth Carbide of North Carolina
NPDES WW Permit No. NCG500315
Davidson County
Dear Mr. Paglia:
Jesse Barnes, of the North Carolina Division of Water Resources (DWR), Winston-Salem
Regional Office (WSRO), conducted a compliance evaluation inspection of the Elizabeth Carbide
of North Carolina facility on February 14, 2023. Mr. James Day, Shop Superintendent, was
present for the inspection. The facility was found to be compliant with the subject permit.
Inspection findings are detailed in the attached Water Compliance Inspection Report.
NPDES certificate of coverage NCG500315 for general permit NCG500000 was issued December
29, 2020 and expires November 30, 2025. There are no special conditions for the subject
permit or certificate of coverage. The plant was restricted to the general public via controlled
access to the private property and secured buildings. The inspector was granted access to all
areas for inspection.
Furnace cooling water was observed to be entirely contained within an automatically operated
closed -loop recycling system. Conditioning chemicals have been added to the cooling water for
corrosion control. The system has been designed to either recycle or vaporize excess cooling
water. When operating properly, no water is discharged from the facility. If a discharge,
overflow, or spill were to occur from the furnace cooling water system, the wastewater would
enter floor drains and be stored in collection basins until it could be pumped and hauled. The
facility has maintained three in -ground collection basins, each having a capacity of
approximately 1000 gallons, for 3000 gallons of total wastewater storage on site at all times.
During the inspection, there were two additional mini -bulk -sized containers available for
temporary storage of wastewater, if needed. There was no known outfall or effluent pipe
discovered during the inspection, nor did facility staff know of any.
If you no longer require a discharge permit, you should apply for rescission. In order to rescind
an NPDES permit the facility owner (or authorized representative) should send a letter including
the permit number, name and address of the facility, and reason for the rescission request to
the NPDES Permitting and Compliance Program at the following mailing address:
