Subject: Nationwide Permit #6
Bridge # 334 on SR 1169 over the South Fork New River
Ashe County, North Cazolina
Project Number (TIP Number): B-3803 (No DWQ Permit Fee)
Dear Mr. Thomas:
The NC Department of Transportation is scheduled to begin the subsurface investigation of bridge
#334 on SR 1169 over the South Fork New River in Ashe County. The existing structure is a
single lane timber decked low water bridge on steel I-beams. The proposed new bridge will be a
200' long 2-lane structure installed at approximately the same location on a slightly different
skew. Four borings within the jurisdictional area will be required at this site to define the
subsurface conditions at the two new interior bent locations. The borings will be advanced using
a rubber tired CME 550 drill machine. A four-inch diameter NW size casing will be advanced to
the hazd rock horizon and rock core samples will be obtained using NXBWL size coring
equipment. Each boring may reach a total depth of approximately 20 feet.
This boring activity will result in a very minor discharge of rock dust, but should not remove or
degrade existing water quality uses. Relatively low stream banks should allow easy access to the
river channel and minimise disturbance to the stream. Appropriate erosion control measures and
BMP's will be employed if necessary to minimise stream impacts and sedimentation. Wastewater
from the drilling rig will be diverted away from the stream and into a riparian buffer whenever
possible. This project will have no effect on any federally listed endangered plant or animal
species.
Attached is a Preconstruction Notification Form, plan sheets, a marked county map, a marked
topography map and photographs.

III. Project Information
Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map

USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be 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.
Geotechnical investigations are necessary to determine what type of replacement structure is
appropriate. All appropriate BMPs will be used during_construction.
Page 7 of 12

VIII. Mitigation
DWQ - In accordance with l5A 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 1 SO 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 March 9, 2000, 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 NCWRP 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/strmgide. 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
description of the current site conditions and proposed method of construction. Please attach
a sepazate sheet if more space is needed.

XIV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
