RE: Dan River Steam Station, Rockingham County, Notification of CornMetion of
Part II, Section 3.(b)(1) of the Coal Ash Management Act of 2014 (Session Law
2014-122) (CAMA)
Dear Secretary Regan:
Please accept this letter as Duke Energy's notification to the North Carolina Department of
Environmental Quality (NCDEQ) that Duke Energy has completed closure of the coal
combustion residuals (CCR) surface impoundments at its Dan River Steam Station in
accordance with CAMA.
Section 3.(b)(1) of CAMA deemed the CCR surface impoundments at Dan River Steam Station
as "high -priority" and required that they be closed no later than August 1, 2019 in accordance
with Section 3.(c), which directs that the impoundments be closed by dewatering and that the
CCR be removed to a permitted landfill or structural fill.
The dewatering and removal of CCR from the Dan River Steam Station surface impoundments
was completed on May 20, 2019. CCR removal was completed in accordance with the Dan
River Steam Station Coal Ash Excavation Plan. As requested by NCDEQ's letter to Duke
Energy dated January 22, 2019,' Duke Energy will submit a report describing (i) where the CCR
was taken and in what amounts, and (li) the results of the actions taken in accordance with
Duke Energy's Excavation Soil Sampling Plan. Duke Energy expects to submit the report by
July 31, 2019.
Duke Energy will continue to comply with all other requirements and deadlines established
under CAMA, including annual inspections, annual reporting, groundwater monitoring, and
groundwater corrective action.
' Although NCDEQ specifically drafted this letter to addresses closure of the high -priority impoundments
at the Riverbend Steam Station, the letter generally establishes NCDEQ's position regarding how Duke
Energy should "demonstrate compliance with Session Law 2014-122's closure requirements."
