QUARTERLY EXCAVATION PROGRESS REPORT
HF LEE PLANT
OCTOBER 24, 2019

Background and Summary
On January 10, 2019,Duke Energy Progress, LLC(DEP)and the North Carolina Environmental Management
Commission entered into a Special Order by Consent— EMC SOC WQ S18-006 (SOC) applicable to the HF
Lee Plant (HF Lee). This report is submitted in accordance with Section 2.b.3) of the SOC. In compliance
with Section 2.b.3), this report summarizes the work and activities undertaken with respect to decanting
work and closure of coal ash surface impoundments at Asheville. The quarterly reports are due no later
than the last day of January, April,July, and October for the duration of the SOC.
The HF Lee Plant is located in Goldsboro, NC (Wayne County) along the Neuse River. The Plant began
commercial operation in 1951. The plant's three coal-fired units were retired in September 2012 and
replaced by four oil-fueled combustion turbine units in October 2012. In December 2012, the HF Lee
Combined Cycle Plant was brought on-line, which applies two sources of energy, combustion and steam
turbines, to convert natural gas to electricity. The Coal Combustion Residuals (CCR) basins associated
with the historical coal-fired energy generation are also located on the site.
The HF Lee Plant has four, regulated CCR basins on site and a Lay of the Land Area (LOLA). The ash basins
cover approximately 307 acres, with a current ash inventory of approximately 6.3 million tons of ash, as
of July 2019. The basins are referred to as:
• Basin 1 or 1950 Inactive CCR Basin (State ID WAYNE-031)
• Basin 2 or 1955 Inactive CCR Basin (State ID WAYNE-032)
• Basin 3 or 1962 Inactive CCR Basin (State ID WAYNE-033)
• Active Basin or 1982 CCR Basin (State ID WAYNE-022)
• Lay of Land Area (LOLA)
The HF Lee site was announced as an ash beneficiation site on December 13, 2016. Ash excavation,
beneficiation, and closure of the HF Lee Ash Basins has not yet begun. Construction, startup, and
performance testing is scheduled to be completed in Q4 2020.
Decanting Status
Prior to the Special Order by Consent, Duke Energy commenced decanting of the HF Lee Active Ash Basin
on November 27, 2017. Decanting was completed on November 2, 2018. Duke Energy has performed
periodic maintenance decanting since that time to maintain the ash basin in a decanted state. Dewatering
of the Active Ash Basin began on July 16, 2019 and will continue throughout beneficial reuse and closure.
