Background and Summary
On March 21, 2019, Duke Energy Carolinas, LLC (DEC) and the North Carolina Environmental
Management Commission entered into a Special Order by Consent—EMCSOC WQS18-009 (SOC)
applicable to Belews Creek Steam Station (Belews Creek). This report is submitted in accordance
with Section 2.c. of the SOC. In compliance with Section 2.c., this report summarizes the work
and activities undertaken with respect to the planning, design, construction and use of the new
outfall to the Dan River. The semi-annual reports are due no later than the last day of January
and July for the duration of the SOC.
The Belews Creek Steam Station is located on Belews Lake in southwestern Stokes County, NC.
Belews Creek is a two-unit, 2240-megawatt coal-fired generating facility. The Station began
commercial operation in 1974 with Units 1 and 2.
Belews Creek operates one Ash Basin for treating sluiced Coal Combustion Residuals (CCR). The .
Ash Basin was constructed from 1970 to 1972 and has been operational since 1974. It received
bottom ash sluiced from the Station until Q4 2018. Regular sluicing of fly ash ended in 1983 when
the Station converted to dry fly ash handling. The Ash Basin has an approximate area of 283
acres and has been an integral part of the Station's wastewater treatment system. The current
ash inventory of the Ash Basin is approximately 12.0 million tons as of April 30, 2019.
Discharges of process wastewater to the Ash Basin ended in March 2019 with the commissioning
of Lined Retention Basin.
Construction Status
In accordance with this SOC, Duke Energy initiated design and construction of new Outfall 006 to
the Dan River to eliminate discharge from Outfalls 003, Outfall 003A and Outfall 111.
Construction of Outfall 006 began on March 15, 2019 and was completed on July 12, 2019.
Discharge from Outfall 003A was eliminated on July 12, 2019. Duke Energy provided notification
of the initiation of construction of Outfall 006 per the SOC on March 27, 2019.
