RE: Sutton Plant New Hanover County, Notification of Com letion of Part it Section
Ub)(4) 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 Sutton Station in accordance with
CAMA.
Section 3.(b)(4) of CAMA deemed the CCR surface impoundments at Sutton 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. This closure date was extended four (4)
months to December 1, 2019 by NCDEQ order, dated March 26, 2019, issued for a Duke
Energy variance request for the Sutton Plant pursuant to NCGS 130A-309-215(a) with
conditions.
The dewatering and removal of CCR from the Sutton Station surface impoundments was
completed on June 24, 2019. CCR removal was completed in accordance with the Sutton
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 (ii) the results of the actions taken in accordance with Duke Energy's
Excavation Soil Sampling Plan. Duke Energy expects to submit the report by August 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."
