Diversion Structure - Additional Rip Rap
TD?S ORMWA R 13POW
?
Dear Mr. Coburn:
Carolina Power & Light Company d/b/a Progress Energy Carolinas requests a modification to the existing
water quality certification which allowed the installation of rip rap for re-establishing certain eroded
sections of the shoreline that was connected to the fish diversion structure.
During the repair of the damaged area it was noticed that at high tide water was coming in behind the
rip rap that was used to stabilize the eroded area. In order to mitigate any further erosion issues PEC
request permission to install approximately 40 more cubic yards of rip rap.
A narrative summary of the project with photographs, detailed drawings and a location map is provided
along with a check for $240.00.
If you have any questions or need any further information please contact at (919) 546-7457.

VIII. Mitigation
Updated 11/1/2005
Page 9 of 12
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina (see DWQ website for most current
version.).
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
None proposed, project is for maintenance of the diversion structure and will affect less
than 0,03 acres of wetland.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
(919) 715-0476 to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://www.nceep.net/pages/inlieureplace.htm. If use of the NCEEP is proposed,
please check the appropriate box on page five and provide the following information:

Project Narrative
The Brunswick Steam Electric Plant (BSEP) has a fish diversion structure at the mouth of the cooling
water intake canal located on the Cape Fear River in Southport, NC. The fish diversion structure was
originally installed in 1982 and is a "V" shaped structure that spans the mouth of the intake canal at a
distance of approximately 400 feet. The diversion structure has fence facings which are designed to
prevent the entrance of fish and turtles into the intake canal. The fish diversion structure has wing walls
which extend into the shoreline on each end of the structure. Fencing is also present beyond the wing
walls and continues along the shoreline. The purpose of the fencing is to also prevent the entrance of
fish and turtles into the intake canal at high tides.
Recent meteorological events have eroded a portion of the shoreline that joined the wing wall on the
north side of the structure and have also caused the fencing to be undermined, and create an open
water gap of approximately 60 feet. The BSEP has re-established the connection of the wing walls with
the shoreline and closed the gap by installing approximately 96 linear feet of sheet pilings with a depth
of approximately 30 feet. The steel sheet pile tip elevation matches the bottom of the existing pre-
-stressed concrete pile cap on the existing wing wall (~ EL. 4'). Rip rap (18"-36" greatest dimension) was
used to stabilize areas vulnerable to erosion. Approximately 80 cubic yards of rip rap was placed along
the shoreline where the steel sheet pile intersects the bank. Approximately 5 cubic yards was placed
where the existing pre-stressed concrete pile overlaps the steel sheet pile. The existing turtle blocker
mesh fencing damaged by the erosion was repaired by installing replacement fencing along the
shoreline. The replacement fencing was routed in the same manner as the originally installed
configuration to prevent the entrance of fish and turtles into the intake canal at high tides.
During the repair of the structure it was noticed that at high tide water was coming in behind the newly
placed rip rap, which has raised concerns about another potential wash out of the shoreline during
heavy storms. This letter requests that the BSEP be allowed to install an additional 40 cubic yards of rip
rap along the shoreline to prevent additional water washing in behind the existing rip rap. This new rip
rap will be placed along a shoreline that is perpendicular to the rip rap that was just installed. Please
see the attached drawings and photographs for further details.
