Dan River Steam Station
After - the -Fact Pre - Construction Notification — New Boat Ramp
Dear Ms. Higgins:
410 S Wilmington St.
Raleigh NC 27601
As you requested on February 10, 2014, Duke Energy Carolinas, LLC. is providing the 401 &
Buffer Permitting Unit an after - the -fact pre- construction notification; for construction of a new
boat ramp at the Dan River Steam Station located in Rockingham County, North Carolina.
The new boat ramp is needed at the Dan River Station for several reasons. Mostly because the
existing ramp is unsafe due to the slope ( >25 %) and in poor condition. Duke Energy proposes
to construct a new ramp approximately 20 feet downstream of the existing ramp. There is a
particular need for the project at this time to provide a safer and more practical access ramp for
future monitoring of the river by Duke and the partnering agencies.
Thank you for your assistance with this project. If you have any questions or comments
regarding this letter please contact Mr. Steve Cahoon of Duke Energy's Environmental Services
Section at (919) 546 -7457 or steve.cahoonP_duke- energy.com.
Sincerely,
Sc eve Cahoon
Sr. Environmental Specialist

Part B. Project Information and Prior Project History
Question 3e. Describe the overall project in detail, including type of equipment to be used:
A new boat ramp will be constructed at the Dan River Station. The existing ramp is very steep ( >25 %), in
poor shape, difficult to access from the river, and unsafe due to the slope and condition. A new ramp
will be constructed approximately 20 feet downstream of the existing ramp. The purpose and need for
the project is to have a safer and more practical access ramp for future monitoring of the river by Duke
and the partnering agencies.
The ramp will be constructed using the heavy equipment on -site. Including track hoes, excavators and
dump trucks. The design of the new boat ramp will be as follows: 1) cut upland slope down to 6% -10%
grade, 2) install crushed rock install crushed rock /riprap pad within OHWM for a maximum length of 20
feet, 3) install pre- formed concrete ramp on top of rock for a maximum length of 20 feet (see "boat
ramp" plan attached for an example). The maximum rock base and concrete ramp width is 20 feet.
