Subject: Request for Permit to Support Dredging of the Discharge Canal Settling
Basin at the Brunswick Steam Electric Plant
Dear Ms. Garvey:
Carolina Power & Light Company, now doing business as Progress Energy Carolinas, Inc.,
is planning to conduct maintenance dredging within the settling basin of the discharge
canal for the Brunswick Steam Electric Plant, which is located in Southport, North
Carolina. Periodic maintenance dredging of the settling basin is needed to ensure adequate
flow of water through the discharge canal pumps. Similar maintenance dredging for the
discharge canal settling basin has been previously requested and permitted.
The maintenance dredging project will remove approximately 60,000 cubic yards of silt
material that has accumulated in the settling basin of the discharge. canal pump station.
The deposited material will be removed and retained in two spoil. ponds located on high
ground adjacent to the discharge canal. Maintenance dredging in this area will restore the
settling basin to its original depth. The Pre-Construction Notification Application Form,.
two vicinity maps, plan views of the discharge canal and spoil ponds, and across-section
diagram of the discharge canal settling basin, are enclosed.
The expected date to start the maintenance dredging project is Apri17, 2008. Based on this
expected start date, issuance of the permit approvals is requested by March 31, 2008..
Since the maintenance dredging project will not meet any of the thresholds found in the
Division of Water Quality's Water Quality Certification #3687 for requiring written
approval, no permit approval is being requested by the North Carolina Division of Water
Quality. However, a courtesy copy of this letter and the Pre-Construction Notification
Application Form are being provided to the North Carolina Division of Water Quality for
their records. The maintenance dredging project will comply with all of the conditions of
certification found in Water Quality Certification #3687.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken. to avoid the proposed impacts. It maybe useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.

VIII. Mitigation
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
Updated 11/1/2005
Page 9 of 12

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 dredging of BNP cooling water discharge
canal settling basin.
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
[phone] 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:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount ofNon-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):
