Subject: Nationwide Permits #14 & # 33
S.R. 1306, Brigmon Hollow Road
State Project No. 130.057103 (DWQ Minor Permit Fee $200)
Madison County, NC
Dear Mr. Baker:
I have enclosed astraight-line diagram with erosion control plan, a PCN application for
NWP #14 & #33, and a vicinity map relative to the proposed project on SR 1306
Brigmon Hollow Road, Madison County, NC.
Brigmon Hollow Road is currently a 14-16 feet wide gravel road. Division of Highways
plans to pave the road 18 feet wide and increase the typical section. Grading will be
moderate.
We propose to extend four (4) pipe culverts on Rock Branch and three UT's. Total
permanent culvert extensions will be 701inear feet with a temporary impervious dike (2-5
feet) for dewatering during installation at each location. Rock Branch is an
approximately 5-foot wide stream with riffle/pool habitats and cobble/gravel boulder
substrate. Bed/bank features are prominent. The UT's varied from 1-2 feet in width with
sand/gravel substrates and bed and bank features.
No stream relocation will be performed for the project. Existing channel morphology
will be maintained upstream and downstream of the culvert. The culverts will be placed
below existing streambed elevation whenever possible. Bedrock is evident within the
streams and may prevent burial of the culverts. Riparian vegetation will be reestablished
along disturbed areas associated with the culvert extensions. Stormwater will be diverted
through grass-lined ditches or vegetated buffers prior to entering streams.
Mr. David Baker

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. The existing secondary road
must be improved to meet current safety standards for paved roads. The nine culvert extensions
rec,~uested are the minimum necessary to establish an apnronriate typical section for the roadway
intersection and maintain the existing stream pattern. Riparian vegetation will be established on
disturbed areas associated with the project construction.
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
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, available at
http://h2o enr state nc.us/ncwetlands!stnn~ide.html.
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
Page 6 of 9
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
We do not feel that mitigation is warranted due to the minimal impacts of the pipe culvert
extensions Additionallypaving of the roadway should eliminate sedimentation from fines
associated with~avel roadway and provide a vegetated shoulder to buffer runoff.
If required we propose to utilize the Ecosystem Enhancement Program (EEP) for the
mitigation requirements for the ~ronosed impacts. NCDOT will be coordinating with the
EEP to obtain the ~propriate mitigation credits if required.
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•//h2o.enr.state.nc.us/wrp/index.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):
