Re: Subsurface Geotechnical Exploration - Supplemental Investigation
Proposed Canal Road Landfill PN: 3623-INDUS-XXXX
Allen Steam Station
253 Plant Allen Road
Belmont, Gaston County, North Carolina
Dear Ms. Moutos,
525 S Tyron Street
Charlotte, NC 28202
DEP36A
Duke Energy Carolinas, LLC (Duke Energy) request approval from the Division of Waste
Management (Division) for a supplemental bedrock and hydrogeologic investigation to support
design and permitting of the proposed Canal Road Landfill (CLF) [3623-INDUS-XXXX] at the Allen
Steam Station.
This supplemental exploration includes additional bedrock coring, hydrologic testing, and
piezometer installation in the vicinity of the proposed CLF. The attached figures and table were
prepared by AECOM on behalf of Duke Energy and include historical, existing, and proposed
investigation locations. A total of four additional subsurface investigation locations are proposed as
shown on the attached figures and summarized in the attached table.
Although not specifically required per the applicable subchapter 13B of the North Carolina
Administrative Code, Duke Energy understands some existing landfill facilities in our fleet have
permit requirements for a Licencesed Geologist to supervise groundwater well installations. For
clarity, Duke Energy request approval from the Division to install four additional piezometers
supervisied by a qualified geotechnical field support that is under the direct supervision of and in
contact with a Licensed Geologist. The four additional piezometers will be installed by a North
Carolina licensed well contractor in accordance with subchapter 02C of the North Carolina
Administrative Code.
I can be reached at [phone] or [e-mail] if you need additional
information or have any questions regarding this request.
