Please give a brief project description below.*

Duke Energy at the Marshall Steam Station is proposing to install a raw
water intake, conveyance pipe, and airburst supply piping at the Marshall
Steam Plant located at 8320 NC-150 in Sherrills Ford, Catawba County,
North Carolina on Lake Norman. The proposed project is located on Duke
Energy properties, with the surrounding shoreline classified as public
infrastructures according to Duke Energy - Catawba-Wateree Federal
Energy Regulatory Commission (FERC) Shoreline Management Plan
(SMP). The 12-inch diameter high -density polyethylene water conveyance
pipe and intake screens are part of the groundwater remediation program
at the Marshall Steam Station.
The groundwater remediation program consists of groundwater extraction
and clean water infiltration. The new intake is designed to accommodate
the flows for the infiltration system as well as to provide water for dust
suppression at the facility that will be necessary during additional remedial
activities. The water for dust control will be used on haul roads, in ash
removal activities, in soil borrow areas and in the landfill construction and
operation activities. For the water used within the ash basin and landfill it
ultimately, if not absorbed, would go to a NPDES permitted system. For
other areas of the project there will not be any run-off from the dust control
operation going offsite. NPDES permit NC0004987 is being modified to
allow for groundwater that is being pumped from the extraction wells for
remediation to be discharged to an on -site wastewater treatment system
prior to discharging from NPDES permitted outfall 002.
To eliminate surface (land and lakebed) disturbance and to facilitate the
distance and depth of the intake screen array's targeted location in the
Lake, the piping will be installed via horizontal directional drill (HDD). The
HDD bore will require an excavated shallow "bore launch" pit roughly 8ft x
8ft x 4ft in which to launch and control the borehead, resulting in
approximately 10 cubic yard of excavation at the pit. The pit will be
backfilled with approximately 10 cubic yard of NCDOT No. 57 stone to
match surrounding and pre -construction lakebed slope and elevation.
Please give a couple of dates you are available for a meeting.
