Subject: Nationwide 14 Permit Application -Revised
SR 1521-A, Mountain Grove Road
Macon County
State Project No. 14C.056106 (DWQ Minor Permit Fee $240)

Dear Mr. Balser:

The North Carolina Department of Transportation (NCDOT) is going to install new pipes on SR
1521-A, Mountain Grove Rd, in Macon County. The proposed improvements of SR 1521-A
have been identified as necessary maintenance and safety improvements. Please note that SR
1521-A and SR1521-B have separate station numbers. See enclosed straight-line diagrams for
station details. Funds have been allocated for this project, and NCDOT would like to perform
these activities sometime during the 2008 and 2009 paving seasons.

I am sending a pipe installation detail as well as a marked county map and USGS quad map. We
propose to install new culverts slightly below the existing streambed elevations where bedrock is
not encountered to minimize impacts to aquatic habitats and allow the existing stream gradients
to remain as unchanged as physically possible. No threatened or endangered species are known
to be present in or near the project area; therefore, no significant impacts are anticipated from
project construction. If the State Historic Preservation Office (SHPO) and the Office of State
Archaeology determines that further investigations are required, NCDOT will conduct the
appropriate site investigations and obtain compliance from SHPO prior to project construction.

The best management practices will be used to minimize and control sedimentation and erosion
on this project. The construction foreman will review all erosion control measures daily to
ensure sedimentation and erosion is being effectively controlled. If the planned devices are not
functioning as intended, they will be immediately replaced with better devices. The rock silt
screens and other erosion control devices will be in place prior to pipe culvert construction and
will remain in place until the project is stabilized.

In order to construct the project in accordance with our current secondary road standards, it will
be necessary to impact waters of the United States in the Little Tennessee River Basin. Site 1 and
Site 2 will not be replaced and will not cause any impacts. Listed below is a summary of the
proposed impacts.

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. The culverts are being placed
the minimum length to widen the shoulder to improve the safety of the roadway.

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 (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

Page 7 of 10

r ~

description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
If mitigation is required for this project. NCDOT will make payment to the NCEEP.

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/inlicureplace.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): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A

IX. Environmental Documentation (required by DWQ)

1. Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes ® No ?
2. If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No

3. If yes, has the document review been finalized by the State Clearinghouse? If so, please
attach a copy of the NEPA or SEPA final approval letter. Yes ? No ?

X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)

It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.

impervious surface. The roadway surface will be approximately 20% of the right-of-way area.
Stormwater will be diverted through settling basins lined with filtering stone or grass lined
buffers prior to entering streams.
