1. Erosion and sediment control practices must be in full compliance with all specifications governing the proper
design, installation and operation and maintenance of such Best Management Practices in order to protect surface
waters standards:
a. The erosion and sediment control measures for the project must be designed, installed, operated, and
maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control
Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be
such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina
Sediment and Erosion Control Manual. The devices shall be .maintained on all construction sites, borrow
sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the
project. r
c. For borrow pit sites, the erosion and sedimenfi control measures must be designed, installed, operated,
and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual.
d. The reclamation measures and implementation must comply with the reclamation in accordance with the
requirements ofthe Sedimentation Pollution Control Act.
2. There shall be no excavation from or waste disposal into, jurisdictional wetlands or waters associated with this
permit without appropriate modification. Should waste or borrow sites be located in wetlands or streams,
compensatory mitigation will be required since that is a direct impact from road construction activities.
3. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this
Certification. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall
be removed and the natural grade restored upon completion of the project.
4. The permittee shall use Design Standards in Sensitive Watersheds [15A NCAC 4B.0124 (a)-(e)]. Temporary cover
(wheat, millet or similar annual grain) or permanent herbaceous cover should be planted on all bare soil within
fifteen (15) days of ground disturbing activities to provide long-term erosion control. Erosion control mating should
be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas. Matting should
be secured in place with staples or wherever possible, live stakes of native trees. Straw mulch and tall fescue should
not be used in riparian areas.
5. Strict adherence to the most recent version of NCDOT's Best Management Practice For Bridge Demolition and
Removal, approved by the US Army Corps of Engineers, is a condition of the 401 Water Quality Certification.
6. Bridge deck drains should not discharge directly into streams. Stormwater should be directed across the bridge and
pre-treated through site-appropriate means (grass swales, pre-formed scour holes, vegetated buffers, etc.) before
entering the stream. Please refer to the most current version of Stormwater Best Management Practices.
7. All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP measures from the
most current version of NCDOT Construction and Maintenance Activities manual such as sandbags, rock berms,
.cofferdams and other diversion structures should be used to prevent excavation in flowing water.
8. For projects impacting waters classified by the NC Environmental Management Commission as Trout (Tr), High
Quality Waters (HQW) or Water Supply I or II (WS-I, WS-II), stormwater shall be directed to vegetated buffer
areas, grass-lined ditches or other means appropriate to the site for the purpose of pre-treating stormwater runoff
prior to discharging directly into streams. Mowing of existing vegetated buffer areas is strongly discouraged.
9. Only clean and sediment free riprap shall be used and placed in surface waters.
10. The post-construction removal of temporary work pads will need to return the project site to its preconstruction
contours and elevations. The impacted areas shall be revegetated with appropriate native species. Disturbed
floodplains and streams should be restored to natural geomorphic conditions.
11. Mussels located in the North Toe River shall be relocated from the proposed impact area, prior to installing in-stream
structures, in accordance with the North Carolina Wildlife Resources Commission recommendations.
12. The existing roadway that is to be eliminated should be restored back to original ground elevations and the natural
floodplain elevations and functions restored. Disturbed. areas should be seeded or mulched to stabilize the soil and
native tree species should be planted with spacing of not more that l oft. x l Oft.
13. Native riparian vegetation (e.g. rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and
red maple) must be reestablished within the construction limits. of the project by the end of the growing season
following completion of construction.

14. Any riprap placed for bank stabilization should be limited to the streambank below the high water mark, and
vegetation should be used for stabilization above the high water elevation. Riprap should not be place in the active
thalweg channel or placed in the streambed in such a manner that precludes aquatic life passage. Bioengineering
boulders or structures should be properly designed, sized and installed.
15. Heavy equipment should be operated from the banks rather than in the stream channels in order to minimize
sedimentation and reduce the introduction of other pollutants into the stream.
16. All mechanized equipment operated near surface waters must be regularly inspected daily and maintained to prevent
contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.
17. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters
is prohibited.
18. If concrete is used during construction (e.g., headwalls), a dry work area should be maintained to prevent direct
contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be
discharged to surface waters due to the potential for elevated pH and possible aquatic life and fish kills.
19. No rock, sand or other materials shall be dredged from the stream channel, except where authorized by this
certification.
20. A copy of this Water Quality Certification shall be posted on the construction site at all times. In addition, the Water
Quality Certification and all subsequent modifications, if any, shall be maintained with the Division Engineer and the
on-site project manager.
21. The permittee and its authorized agents shall conduct its activities in a manner consistent with State water other
appropriate requirements of State or Federal law. If DWQ determines that such standards or laws are not being met.
(including failure to sustain a designated achieved use) or that State of Federal law if being violated, or that further
conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification.
22. During the construction of the project, no staging of equipment of any kind is permitted in waters of the U.S. or
protected riparian buffers.
23. Upon completion of the project, the NCDOT Division Engineer, shall complete and return the enclosed "Certificate
of Completion Form" to notify NCDWQ when all work included in the §401 Certification has been completed. This
form shall be returned to the Transportation Permitting Unit of the NC Division of Water Quality, 2321 Crabtree
Blvd., Suite 250, Raleigh, North Carolina 27604.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act
within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to
Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service
Center, Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a
hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have
any questions, please telephone Mr. Mike Parker of the Asheville Regional Office at 828.296.4500.

Please find enclosed a copy of the Categorical Exclusion {CE), Pre-Construction Notification form
(PCN}, permit drawings, .roadway plans, stormwater management plan, and the U.S. Fish and Wildlife
Service Biological Opinion for the above referenced. project, A Nationwide 23 and 33 Permit
Application was previously submitted on June 1, 2004. Due to the delays in obtaining the Biological
Opinion the first application was verbally put on hold by the USACE. This permit application replaces
the June 1, 2004 application.. The North Carolina Department of Transportation (NCDOT} proposes to
replace existing Bridge No. 143 on SR 1304 over the North Toe River [DWQ Index # 7-2-{27,7), Class
"C; TR"] on the Yancey and Mitchell County line. The project involves replacing Bridge No. 143 on a
new alignment to the northwest of the existing structure. During construction, traffic will be maintained
on the existing bridge.
IMPACTS TO WATERS OF THE UNITED STATES
Genera] Descri tion: The. water resource within the project area for B-2848 is the North Toe River. The
North. Carolina Department of Environment and Natural Resources classifies the North Toe River as "C
Tr". The DWQ Index number is 7-2-(27.7) for this portion of the river that is located in the Hydrological
Cataloging Unit 06010108.
Permanent Impacts: The North Toe River will be impacted by the proposed project. Construction of the
proposed project will result in less than 0.01 acre {100 square feet) of permanent impacts to jurisdictional
surface waters, from the construction of bridge piers.

Temporary Impacts: The North Toe River will be temporarily impacted by the proposed project.
Construction of the proposed project will result in a total of 0.35 acre of temporary impacts to
jurisdictional streams, in the form of temporary rock causeways and temporary support structures (see
permit drawings). Temporary rock causeways will be used to provide access for equipment during
construction of the new structure and removal of the old bridge once the riew bridge is in place. It is
assumed that the contractor will begin construction of the proposed temporary rock causeways shortly
after the date of availability for the project. The Let date at the time of this application is January 16,
2007 with a review date of November 28, 2006.
Restoration Plan: Upon completion of the new bridge, the temporary fill will be removed from the North
Toe River, to natural grade and the area will be planted with native grasses and or tree species as
appropriate.
Utility Impacts: There will be no impacts from utilities with this project.
BRIDGE DEMOLITION
The existing Bridge No. 143 is a one-lane structure with five spans totaling 367-feet. The superstructure
consists of a reinforced concrete deck, asphalt wearing surface, and metal guardrails. The substructure
consists of reinforced concrete earth-filled spandrel arches, reinforced concrete abutments, and
reinforced concrete piers. The depth from roadway crown to the streambed is approximately 28-feet.
The NCDOT will adhere to appropriate guidelines for bridge demolition and removal including those
presented in "Pre-Construction Guidelines for Bridge Demolition and Removal", "Policy: Bridge
Demolition and Removal in Waters of the United States", "Best Management Practices for Bridge
Demolition and .Removal", "Best Management Practices for the Protection of Surface Waters", and
"Design Standards in Sensitive Watersheds".
FEDERALLY-PROTECTED SPECIES
As of April 27, 2006 the U.S. Fish and Wildlife Service (USFWS) lists nine federally protected species
(Table 1) for Yancey County, and ten for Mitchell County (Table 2). Federal Status and Biological

AVOIDANCE AND MINIMIZATION
The NCDOT is committed to incorporating all reasonable and practicable design features to avoid and
minimize ,jurisdictional impacts. Avoidance measures were taken during the planning and NEPA
compliance stages; minimization measures were incorporated as part of the project design.
Of the three reasonable and feasible alternatives considered, the chosen best minimizes impacts to the
sensitive natural ecosystems in the vicinity of the project site, and provides the most economic design. In
addition, "Design Standards in Sensitive Watersheds", NCDOT's guidelines for "Best Management
Practices for the Protection of Surface Waters", and "Guidelines for Construction Adjacent to Trout
Waters" will be enforced throughout the duration of the project construction.
Since this project will be affecting the federally-protected Appalachian elktoe, areas adjacent to the
project site will be regarded as "Environmentally Sensitive Areas" on the Erosion Control Plans. Please
refer to the project commitments for additional detail.
REGULATORY APPROVALS
Section 404 Permit: It is anticipated that the temporary work bridge .across the North Toe River will be
authorized under Section 404 Nationwide Permit 33 (Temporary Construction Access and Dewatering).
We are, therefore, requesting the issuance of a Nationwide Permit 33 authorizing temporary rock
causeways in the North Toe River. All other aspects of this project are being processed by the Federal
Highway Administration as a "Categorical Exclusion" in accordance with 23 CFR § 771.115(b). The
NCDOT requests that these activities be authorized by a Nationwide Permit 23 (FR number 10, pages
2020-2095.; January 15, 2002).
Section 10 Permit: We are requesting the issuance of a Section 10 Permit for the construction of this
project in navigable waters of the United States (33 U.S.C. 403).
.Section 401 Certification: We anticipate 401 General Certifications numbers 3403 and 3366 will apply to
this project. In accordance with 15A NCAC 2H .0501(a) we are providing two copies of this application
to the North Carolina Department of Environmental and. Natural Resources, Division of Water Quality,
for their records.

STORMWATER MANAGEMENT PLAN
October 3, 2006
Project: 32728.1.1 (B-2848)
Brunswick County, North Carolina
Hydraulics Project Engineer: Henry Wells, PE
NCDOT Hydraulics Project Engineer: Marshall W. Clawson, PE
Project Description:
This project consists of replacing NCDOT Bridge #143 over North Toe River on SR
1304. The existing 367 foot long bridge with a 12 lane, which will be replaced on new
location just up stream of the existing bridge with a 365 foot long bridge. The overall
length of the project including the bridge, approaches, L-line and Y- .line improvements is
1241 feet.
Environmental Description
This project is~located in the French Broad River Basin. This bridge crosses a portion of
the North Toe River, which is inhabited by the Appalachian Elktoe.. The North Carolina
Department of Environment and Natural Resources classifies the North Toe River as "C
Tr". No wetlands are located on this project. No buffers were located in the vicinity of
this project.
Roadway Description:
The proposed roadway bridge approaches will .have 10 foot .lanes and 2 foot paved
shoulders. The project drainage system consists of grated inlets and associated pipe
systems.
Best Management Practices and 1VIaior Structures:
• Major Structure
Abridge will be placed from -L- Station 10+15 to -L- Station13+80. In
accordance with current guidelines, the bridge is designed so that the spill-
thru abutments or vertical abutment are located a minimum of 10 feet from
the top of bank on the line backside of the bridge. The bents in the
channel were minimized. The existing bridge had three bents in the
channel, while the proposed bridge has only one. The bridge is also
designed so that no deck drains will be used in order to stop any direct
discharges into North Toe River. All deck drainage will be picked up by
a deck drainage system and discharged into a preformed scour hole..

Dear Mr. Sullivan:
Subject: Bridge Replacements over the Toe River{Projects B-1443 and B-2S4~) in Yancey and
Mitchell Counties, North Carolina, and Their Effects on the Federally Endangered
Appalachian Elktoe and Its Designated Critical Habitat
This document transmits the U.S, Fish and Vb'ildlife Service's (SenTice) Biological Opinion
{Opinion} based on our review of the Biological Assessment (BA) on the effects of the subject
bridge replacements on the Appalachian elktoe and its designated critical habitat in accordance
with section 7 of the Endangered Species Act (Act) of 1973, as aisierided {16 U.S_C. 1531 et seq.}
{.Act}.
This Opinion is based on information provided in the May 12, .2005, BA; supplemental
infornation To the BA (requested June 23, 2005, and received February 2"t, 2006); other
available literature;-personal communications with e.~perts on the federally endangered
Appalachian elktoe (Alasmidvnta raveneliana); and other sources of information. A complete
administrative record of this consultation is on file at this. office.
In the BA, you determined that the following .federally listed species would not be affected by
the proposed bridge replacements: Carolina northern flying squirrel (Glaucomys sabrinus
coloratus), Virginia big-eared bat {Corynorhinus townsendii virginianus), Indiana bat {Myotis
sodalist}, Eastern cougar (Prima concalor eouguar), spruce-~f3r rr~oss .spider (Mier©herura
mantivaga), Virginia spiraea {Spiraea virginiana}, spreading ovens (Geum radiatum), Helier's
blazing star {Liatris lzelleri~, Roan Mountain bluer (Hedyotis purpurea var. montana), Blue
Ridge goldenrod {Salidago spithamaea), and rock gnome lichen (Gymnoderma lineage). in view
of the informa#ion in the BA, we concur with your determination that the bridge replacement
projects will have no effect on these species. Therefore, eve believe the requir~rzaents under

section 7 of the Act are fulfilled for these species. However, obligations under section 7 of the
Act must be reconsidered if: (1) new information reveals impacts of this identified action that
may affect listed species or critical habitat in a manner not previously considered, (2) this action
is subsequently modified in a manner that was not considered in this review, or (3) a new species
is listed or critical habitat is determined that may be affected by the identified action.
Migratory Birds -Swallows were observed nesting at bridge B-2848. The Migratory Bird
Treaty Act (16 U.S.C. 703-712) prohibits the taking, killing, possession, transportation, and
importation of migratory birds (including the bald eagle), their eggs, parts, and nests, except
when specifically authorized by the Department of the Interior..Both bridges should be
inspected .for nesting migratory birds. The North Carolina Department of Transportation
(NCDOT} should avoid impacting the nests during the migratory bird nesting season of March
through September. Therefore, if birds are discovered nesting on the bridges, demolition of the
bridges should take place outside this nesting season. If it is not~possible to demolish the bridges
outside the nesting season, the NCDOT should work, in consultation with us,.to develop
measures to discourage birds from establishing nests on the bridges by means that will not result
in the take of birds or eggs.
CONSULTATION HISTORY
A consultation history of this project is provided in Appendix A.
BIOLOGICAL OPINION
I. DESCRIPTION OF THE PROPOSED ACTION
As defined in the Service's section 7 .regulations (50 CFR 402.02), "action" means "all
activities or programs of any kind authorized, funded, or carried out, in whole or in part, by
federal agencies in the United States or upon the high seas." The action area is defined as
"all areas to be affected directly or indirectly by the federal action and not merely the
immediate area involved in the action." The direct and indirect effects of the actions and
activities must be considered in conjunction with the effects of other past and present
federal, state, or private activities, as well as the cumulative effects of reasonably certain
future state or private activities within the action area. This Opinion addresses only those
actions from which the Service believes adverse effects may result. In their BA, the
NCDOT outlined those activities involved in the construction and demolition of two
bridges (Projects B-1443 and B-2848) that would affect the Appalachian elktoe and its
designated critical habitat. The NCDOT also considered the effect of their proposal to
protect at least 3,000 linear ft of 100-ft riparian buffers along the. Toe, North Toe, and Cane
Rivers. This Opinion addresses whether replacing these existing bridges is likely to
jeopardize the continued existence of the Appalachian elktoe or adversely modified its
designated critical habitat.
The NCDOT has determined that the subject two bridges are deficient because of
deteriorating structural integrity and are functionally obsolete due to narrow roadway
2

geometry and substandard design. The proposed action calls for the NCDOT to replace
and demolish Bridge Nos. 61 and 143 over the Toe River as follows:
Project B-1443 -The existing Bridge No. 61 over the Toe River on SR 197 was
constructed in 1925 and is a continuous reinforced concrete closed-spandrel arch structure.
It is comprised of five spans, is 270 feet (ft) in length, has a roadway width of 15.6 ft, and
has two piers within the river channel totaling an area of 151.2 ft'. Six alternatives to
replacing the bridge were considered, including five build alternatives. The chosen
alternate will require the least amount of roadway approach construction and was designed
to minimize impacts to the river. The new bridge will be on a new alignment,
approximately 180 ft upstream of the existing bridge. It will be approximately 360 ft in
length and 36 ft wide and will require two piers to be placed in the river, which will result
in 57 ft'` of fill within the channel. Improvements to the approach roadways will be
required for a distance of approximately 213 ft to the south and 59 ft to the north. Traffic
will be maintained on the existing bridge during construction.
The use of temporary bridges for construction and demolition activities is not feasible for
this project due to the amount of bedrock present at the construction site. A drilled shaft
structure will need to be used for any type of bridge at this site since the presence of
bedrock makes pile driving impossible. Given the deteriorated condition and small size of
the existing bridge, it is not possible to work from the existing bridge to construct the new
bridge.. Therefore, rock causeways will be required to construct the new bridge and
demolish B-1443. The temporary construction demolition causeways used for the project
were designed to result in the least amount of fill in the river while providing sufficient
area to accomplish the construction and demolition. The rock causeways will consist of a
base of clean class II riprap, with about 1 ft of clean class I riprap on top of the causeways.
'The causeways will be constructed with pipes to maintain linear flow of the river by
passing water through the causeways. The construction of the causeways will follow a
phasing plan to minimize impacts to the flow of the river; at the narrowest point, 50 percent
of the river will be open. Constructing the piers for the new bridge and demolishing the
existing bridge causeways will result in 4,972 ft2 and 3,993.4 ft2 of temporary rock fill in
the river, respectively.
Concrete arch bridges are difficult to demolish because, when trying to dismantle the
bridge, the entire structure acts as one piece. Historically, the preferred method of
demolition. for concrete arch bridges was removal with explosives. This method of
demolition caused the entire structure to drop into the waterway. To minimize impacts
from the bridge demolition and reduce the potential for the entire bridge to fall into the
river, the NCDOT has proposed that the contractor construct a support frame at the existing
bridge (as discussed later in this document, the contractor will be required to submit for
approval a demolition plan that provides construction and demolition techniques that
provide equal to or fewer impacts than described in the BA). Temporary support frames
will be placed in the river under each arch. The support frame foundation will most likely
be precast concrete (such as a concrete barrier), but the contractor may choose to use a
timber or steel foundation.. Due to the irregular rock streambed, small amounts of riprap or
sandbags may be required to level up the support frame foundation..

Project B-2848 -The existing Bridge No. 143 over the Toe River on SR 1304 was
constructed in 1922 and is a reinforced concrete spandrel arch structure. The bridge
consists of earth-filled spandrel piers. It is comprised of five spans, is 367 ft in length, has
a roadway width of 12 ft, and has three piers within the river channel totaling an area of
349 ft'. Five alternatives to replacing the bridge were considered, including three build
alternatives. The chosen alternative will have less impact on the natural environment than
the other two build alternatives and will avoid impacting a tributary to the Toe River. The
new bridge will be on a new alignment, approximately SO ft downstream of the existing
bridge. It will be approximately 366 ft in length and 24 ft wide. It will require one bent,
consisting of two drilled piers totaling 32.0 ft2, and another bent with similar dimensions
will be constructed. at the water's edge on the east bank of the river.
As with B-1443, the use of temporary bridges for construction and demolition activities is
not feasible for this project due to the amount of bedrock present at the construction site.
The rock causeways that will be required to construct the new bridge and demolish B-2848
were also designed to result in the least amount of fill in the river while providing sufficient
area to accomplish the construction and demolition. The rock causeways will consist of a
base of clean class II riprap, with about 1 ft of clean class I riprap on top of the causeways.
The causeways will be constructed with pipes to maintain linear flow of the river by
passing water through the causeways. The construction of the causeways will follow a
phasing plan to minimize impacts to the flow of the river; at the narrowest point, 52 percent
of the river will be open. Constructing the piers for the new bridge and demolishing the
existing bridge causeways will result in 15,SS 1 ft2 and 1,786 ft2 of temporary rock fill in
the river, respectively.
The NCDOT will also use support frames, as described for the demolition of B-1443, to
minimize impacts from the bridge demolition and reduce the potential for the entire bridge
to fall into the river. In addition to the difficult nature of demolishing concrete arch
bridges, the piers at B-2848 are also filled with earthen material. The NCDOT has
proposed the removal of this fill in the .initial steps of the demolition process to ensure that
the fill material does not enter the river.
A. Action Area
The action area for this Opinion includes the areas directly impacted by construction
activities; the areas potentially impacted by indirect impacts; a 100-ft (S00-meter [m])
boundary around each bridge site, which includes 1,312 ft (400 m) downstream and
328 ft (100 m) upstream of both the existing and newly constructed bridges; and the
areas the NCDOT is considering for riparian buffer preservation and/or restoration
along the Toe, North Toe, and Cane Rivers to help offset impacts from the project.
Therefore, the project area includes the main stem of the North Toe River, Toe River,
and. Cane River in Mitchell and Yancey Counties, North Carolina (see attached
Figures 1 and 2).

Phvsical Characteristics within the Action Area -The South Toe River and North Toe
River combine near the Town of Spruce Pine to form the Toe River; the Toe River then
combines with the Cane River to form the Nolichucky River, a tributary to the French
Broad River. The North Toe River originates in central Avery County, approximately
5 miles northeast of Newland. From Newland the river flows east for approximately
4 miles to Minneapolis. The river generally flows in a southwest direction from
Minneapolis, through the city of Spruce Pine in Mitchell County, until its confluence
with. the South Toe River near Kona, forming the Toe River. The Toe River continues
to flow northwest along the MitchelUYancey County border through Toecane and
Relief until its confluence with the Cane River near Huntdale. The headwaters of the
Cane River arise in Mount Mitchell State Park in Yancey County. The Cane River
flows generally south for approximately 40 miles before joining the Toe River near
Huntdale to form the Nolichucky River.
The Nolichucky River watershed occupies parts of two physiographic provinces.
Upstream parts of the watershed (upstream from about Dry Creek, at river mile 87.5)
and the higher slopes along the eastern side of the river are in the Blue Ridge Province.
The remainder of the watershed and most of the length of the Nolichucky River are
located in the Valley and Ridge Province. The approximately one-third of the
watershed that is located in the Blue Ridge Province consists of high,. steep ridges with
narrow valleys. The mountains in this part of the watershed rise 1,000 to 2,500 ft above
the adjacent lowlands. The western part of the Blue Ridge Province is characterized by
long, narrow individual ridges, aligned parallel to the trend of the range and similar to
the more subdued ridges of the Valley and Ridge Province. The main mountain mass
along the Tennessee/North Carolina state line is a tumbled confusion of peaks and
valleys that appear to have no regular pattern.
Land Use - Most of the land in the action area is forested, with a large portion of it
occurring within the Pisgah National Forest.. A .significant portion of land, mostly
along the alluvial areas of the middle North Toe River, South Toe River, and Toe
River, is residential/golfrnurse (<1 percent) or cultivated cropland and pasture
(14 percent) (North Carolina Department of Environment and Natural Resources
[NCDENR] 2005). Historically, the economy of the entire Nolichucky River subbasin
depended on natural resources. The mining of mica, feldspar, kaolin, or olivine in the
Spruce Pine mining district within the North Toe and South Toe watersheds was the
.main source of income for the area.
Ecolo icg al Significance -The Nolichucky River subbasin is known to support a
number of rare fish and freshwater mussel species (Table 1). The stonecat (Noturus
flavus) is found only in North Carolina in the Nolichucky and Little Tennessee River
watersheds. The Cane River contains several rare animals, the most notable of which is
almost the entire North Carolina population of sharphead darter (Etheostoma
acuticeps). The lower stretches of the North Toe and Nolichucky Rivers provide
habitat for the olive darter (Percina squamata), logperch (Percina caprodes), and
tangerine darter (Percina aurantiaca), as well as the federally endangered Appalachian
elktoe mussel. The wavy-rayed lampmussel (Lampsilis fasciola) and the hellbender

(Cryptobranchus alleganiensis) have been found in the same reaches of the upper

The North Carolina Natural Heritage Program (NCNHP) maintains a database of rare
plant and animal species, as well as significant natural areas, for the State of North
Carolina. Natural areas (sites) are inventoried and evaluated on the basis of rare plant
and animal species, .rare or high-quality natural conununities, and geological features
occurring in the particular site. These sites are rated with regard to national, state, and
regional significance. The aquatic habitat of the South Toe, a portion of the North Toe,
the Toe, and the Nolichucky River is considered to be of "National Significance," and
the aquatic habitat of the Cane River is considered to be of "Statewide Significance."
Water uality Assessment and Best Usage Classification -Historically, sedimentation
and pollution from. several mining operations throughout the Nolichucky River
subbasin (primarily in the North Tae watershed) significantly degraded cool-warm
water habitats (North Carolina Wildlife Resources Commission [NCWRC] 2005).
Feldspar, mica, and. kaolin have been extensively mined in this watershed in North
Carolina since the early 1900s (Muncy 1981). Nearly half of the .nation's mica is
produced in this region. Sedimentation from mining and agricultural practices in the
subbasin is well documented (Tennessee Valley Authority [TVA] 1981, Ahlstedt and
Rashleigh 1996). However, the~North Carolina Mining Control Act of 1971 and the
Sedimentation and Pollution Control Act of 1973 have helped improve the water
6

quality of this basin (NCDENR 2003, AhIstedt and Rashleigh 1996). Recent
bioassessments, including benthic macrouivertebrate and fish sampling, in the
Nolichucky River subbasin by the North Carolina Division of Water Quality {DWQ)
indicate improving conditions in the subbasin (Tables 2 and 3).
While the sampling conducted by DWQ indicates that water quality is generally good
in the subbasin (based on the parameters that are sampled and evaluated by the DWQ),
there are still areas of concern. Mining impacts are still widespread, while croplands
for corn, tomatoes, and burley tobacco, along with development, contribute to
nonpoint-source pollution, including pesticides, fertilizers, oil, heavy metals, animal
waste, and eroded sediment, that are washed from land or paved surfaces when it rains.
Overall, sedimentation has been considered a significant problem in the Nolichucky
River system for many years. Habitat in the North Toe River between Spruce Pine and
its confluence with the South Toe River continues to be degraded, .seemingly from
discharges and runoff from mining operations and the town of Spruce Pine. Floodplain
gravel mining in the upper Cane River watershed, both permitted and unpertnitted
actions, presents a potential threat to long-term channel stability and habitat quality.
Development is increasing throughout much of the subbasin, and erosion and
sedimentation may also be on the rise. Portions of the subbasin may also be impacted
by the direct, indirect, and secondary impacts associated with road construction
activities as a result of the expansion of NC 19 from Burnsville to Spruce Pine
(NCWRC 2005). .
The NCDENR assigns a best usage classification) to all the waters of North Carolina.
These classifications provide for a level of water quality protection to ensure that the
designated usage of that water body is maintained. The portions of the Toe River, Cane
River, and North Toe River that are occupied by the Appalachian elktoe have a
"Class C, Trout," usage classification, and the Nolichucky River from its source to the

include municipal (city and county) and industrial wastewater treatment facilities, small
domestic discharging treatment systems (i.e., schools, commercial offices, subdivisions,
and individual residences), and storm-water systems from large urban areas and
industrial sites. The primary substances and compounds associated with point-source
discharge include nutrients, oxygen-demanding wastes, and toxic substances (such as
chlorine, ammonia, and metals).
Under Section 301 of the Clean Water Act of 1977 (CWA), the discharge of pollutants
into surface waters is regulated by the Environmental Protection Agency. Section 402
of the CWA establishes the National Pollutant Discharge Elimination System (NPDES)
permitting program, which delegates permitting authority to qualifying states. In North
'Water quality monitoring programs have been implemented by the DWQ to assess water quality trends in North
Carolina Waters. One method used is the monitoring of benthic macroinvertebrates to assess water quality by
sampling for selected benthos organisms. The species and overall biomass, as well as the presence of various
groups intolerant of water quality degradation, are reflections of water quality. A biodiversity rating is given to a
water body sampled, based on the taxa richness of the stream, and a qualitative sampling for intolerant forms such as
mayflies (Ephemeroptera), stoneflies (Plecoptera), and caddisflies (Trichoptera), collectively referred to as EPT.
Biodiversity ratings include: Excellent, Good, Good-Fair, Fair, and Poor. Excellent and Good ratings indicate that
the best usage classification for that stream is being supported (S). A rating of Good-Fair indicates that the usage is
supported but is threatened (ST). A Fair rating relates to a partial support (PS) of the best usage, and a Poor rating
indicates that the best usage classification for that stream is not being supported. (NS).

Carolina, the NCDENR's DWQ is responsible for permitting and enforcement ofthe
NPDES program. There were 23 NPDES permitted discharges in the subbasin in 2003
(NCDENR 2005), although additional discharges have been permitted recently (a new
wastewater treatment plant [WWTP] discharge into the South Toe below
Highway 19E). Most of these discharges are small WWTPs that serve.schools or
subdivisions, including the Spruce Pine WWTP, Newland WWTP, Bakersville WWTP,
and multiple mining process discharges, including Unimin's four discharges.
Nonpoint-source Pollution -Nonpoint-source pollution refers to runoff that enters
surface waters through storm water or snowmelt. There are many types of land-use
3The Fish Community Assessment assigns an Index of Biotic Integrity (IBI), which is another method of assessing
water quality. The IBI evaluates species richness and composition, trophic composition, and fish abundance and
condition.
9

activities that are sources ofnonpoint-source pollution, including land development,
construction activity, animal waste disposal, mining, and agriculture and forestry
operations, as well as impervious surfaces, such as roadways and parking lots. Various
nonpoint-source management programs have been developed by a number of agencies
to control specific types ofnonpoint-source pollution (e.g., forestry, pesticide, urban,
and construction-related pollution). Each of these management programs develops Best
Management Practices (BMP) to control the specific type ofnonpoint-source pollution.
The Sedimentation and Erosion Control Program (SECP) applies to construction
activities, such as roadway construction, and is established and authorized under the
Sedimentation Pollution Control Act of 1973. This act delegates the responsibility for
its administration and enforcement to the NCDENR's Division of Land Resources
(DLR) (Land Quality Section). The SECP requires, prior to construction, the
submission and approval oferosion-control plans on all projects disturbing one or more
acres. On-site inspections by DLR are conducted to determine compliance with the
plan and to evaluate the effectiveness of the BMP that are being used. The NCDOT, in
cooperation with the. DWQ, has developed asedimentation-control program for
highway projects, which adopts formal BMP for the protection of surface waters.
Additional erosion-control measures, as outlined in Design Standards in Sensitive
Watersheds (NCAC T15A:04B.0124), are implemented by the NCDOT for projects
within WS-I or WS-II water supply watersheds, critical areas, waters designated for
shellfishing, or any waters designated by the DWQ as High Quality Waters. When
crossing an aquatic resource containing a federally listed species, the NCDOT has
committed to implement erosion-control guidelines that go beyond both the standard
BMP, as well as the Design Standards .in Sensitive Watersheds, regardless of the DWQ
classification. These areas are designated as "Environmentally Sensitive Areas" on the
erosion-control plans.
B. Conservation Measures
Conservation measures represent actions, pledged in the project description, that the
action agency will implement to minimize the effects of the proposed action and further
the recovery of the species under review. Such measures should be closely related to
the action and should be achievable within the authority of the action agency. The
beneficial effects of conservation measures are taken into consideration in the Service's
conclusion of a jeopardy versus a nonjeopardy opinion and in the analysis of incidental
take. However, such measures must minimize impacts to listed species within the
action area in order to be factored into the Service's analyses.
The following conservation measures are proposed by the NCDOT to avoid and/or
minimize potential impacts from construction and demolition activities to the
Appalachian elktoe. These measures have been incorporated into the design and
implementation plans for the bridge replacement projects.
10

Conservation Measures for Bridge Design
Deck drains will be placed at the ends of the replacement bridges. Storm water will
be directed into catch basins and will then. flow through a vegetated buffer so that
no drainage will occur over the Toe River. Currently, drainage from the decks of
both the existing structures flows directly into the river. Storm water coming off
the approaching roadways at the bridge locations wilt be managed in a similar
manner. These commitments have been incorporated in the Structure Design Plans
for each project.
2. The replacement of B-1443 will result in two piers placed within the river, the same
number of piers as the existing bridge; however, the piers of the new bridge will
impact 57 ft'- of the riverbed, while the existing bridge piers are over two and a half
times that size--151.2 ftz. The replacement of B-2848 will reduce the number of
piers within the water as well as the area of impact to the riverbed. The existing
bridge has three piers within the river channel, totaling an area of 349 ft2, whereas
the new bridge will require one bent, consisting of two drilled piers totaling 32.0 ft2
and another bent with similar dimensions at the water's edge on the east bank of the
river. The reduction in the area and the number of piers in the Toe River is
expected to reduce the bridges' effects on stream-flow patterns at these sites.
Conservation Measures for Bridge Construction
The NCDOT will remove Appalachian eIktoes from the impact site and relocate
them to suitable locations upstream of the impacted areas in the North Toe River, at
river mile 25.5, according to the procedures in the approved relocation plan in the
BA.
2. In addition to relocating all. mussels found in the footprint of the impact area, the
NCDOT will conduct final mussel surveys in the project footprint just prior to
construction and will move any additional mussels found to the above-described
upstream habitat.
3. North Carolina sedimentation regulations, entitled "Design Standards in Sensitive
Watersheds,"4 will be implemented during the design and construction of the
4DESIGN STANDARDS IN SENSITIVE WATERSHEDS,ISA NCAC 04B.0124: (a) Uncovered areas in
HQW zones shall be limited at any time to a maximum total area within the boundaries of the tract of 20 acres.
Only the portion of the land-disturbing activity within a HQW zone shat l be governed by this Rule. Larger areas

projects, as applicable. In addition to these standards, erosion-control measures for
environmentally sensitive areas will be implemented and will:
a. Identify areas adjacent to the Toe River as "Environmentally Sensitive Areas"
on the erosion-control plans for this project;
b. Provide a 50-ft buffer zone (each side of the stream), allowing clearing but not
grubbing until immediately before grading operations;
c. Limit grubbing operations to within 10 days of grading;
d. Require "seeding and mulching" to be performed immediately following grade
establishment;
e. Require "staged seeding"--20-ft fill sections or 2 acres, whichever is less;
f. Clean erosion and sediment control measures when half full;
g. Increase sediment storage capacity above standard BMP guidelines; the amount
of increase will be determined during the preconstruction meetings.
Conservation Measures for Bridge Demolition
The contractor will be required to submit for approval a demolition plan to the Resident
Engineer and the Bridge Construction Engineer prior to beginning bridge removal.
This plan must be sealed by a registered North Carolina Professional Engineer. The
plan must use demolition techniques that minimize the amount of debris that will enter
the river and may include procedures similar to those listed below. If the contractor
provides procedures that do not follow those described below, they will be reviewed for
approval by the NCDOT Resident Engineer and Bridge Construction Engineer and the
Service and .must be techniques that. provide equal to or fewer impacts than described
below.
1. Prior to bridge demolition, all the asphalt-wearing surface will be removed from the
deck in a manner that prohibits material from entering the river. Approved removal
techniques include milling or scrapping with a backhoe bucket. Depending on the
technique used, containment headers may be required. Typically, this consists of
Manual for Conservation Practices" or according to procedures adopted by any other agency of this state or the
United States or any generally recognized organization or association. (d) Newly constructed open channels in
HQW zones shall be designed and constructed with side slopes no steeper than two horizontal to one vertical if a
vegetative cover is used for stabilization unless soil conditions permit a steeper slope or where the slopes are
stabilized by using mechanical devices, structural devices or other acceptable ditch liners. In any event, the angle
for side slopes shall be sufficient to restrain accelerated erosion. (e) Pursuant to G.S. l 13A-57(3) provisions for a
ground. cover sufficient to restrain erosion must be provided for any portion of aland-disturbing activity in a HQW
zone within 15 working days or 60 calendar days following completion of construction or development, whichever
period is shorter.

a
vertical boards attached to the bottom of concrete barrier rail to prevent material
from spilling into the river during removal.
2. For B-2848 the fill material within the piers will then be removed. The NCDOT
has proposed that the contractor conduct the removal of the fill material by the
following process: a backhoe will load the material into dump trucks, working
from one end of bridge to the other. After as much fill material as possible is
removed with. the machinery, the rest of the material will be removed manually (by
shovel). The manual removal of the deepest areas of the piers may have to occur
after the upper portions of the pier have been removed.
3. For B-1443 the next step of the demolition process will be to remove all the
concrete rail and deck by saw-cutting or nonshattering methods. This material will
be removed from the bridge without dropping material into the stream. For B-2848
the existing steel beam guardrail will be removed by unbolting and cutting as
needed.
4. At this time in the demolition process the bridge superstructure of B-1443 will
consist of the concrete arches connected by small concrete beams (concrete
diaphragms). The B-2848 superstructure will consist of concrete arches connected
by a solid concrete floor. Portions of the concrete deck will be removed by
saw-cutting and lifting out large pieces. Removing portions of the floor will reduce
the weight of the structure for the next step of demolition. However, like the
concrete diaphragms, some portion of the floor must remain to keep the arches from
separating.
At this point in the demolition process the remaining portion of the bridge will be
dismantled; every attempt will be made to prevent components of the bridge from
dropping into the river. Temporary support frames will be placed in the river under
each arch. The support frame foundation will most likely be precast concrete (such
as a concrete barrier), but the contractor may choose to use a timber or steel
foundation. Due to the irregular rock streambed, small amounts of riprap or
sandbags may be required to level up the support frame foundation. Support frames
will need to be placed in at least three locations under each arch (midspan and
quarter points). The arches will then be sawed into sections and an attempt will be
made to lift these sections out with a crane. The arches could potentially separate,
and all or a portion of them could fall into the river. The contractor's demolition
plan will detail the maximum amount of the bridge that. can be safely removed.
Any portion that falls into the stream will be lifted out with a crane.
6. The proposed causeways will be used as access for bent removal. Equipment will
need to be staged adjacent to the bent in order to facilitate sawing it into
manageable sections above water elevation. Cranes on the causeways will lift the
sections out. Once the bents have been removed to water .elevation, the remaining
mass of concrete will be removed to streambed elevation by underwater sawing or
the use of a hoe ram to break the bent at streambed interface to allow for lifting it
13

~ a
out as a unit. During this process, turbidity curtains will be used (if water depth is
sufficient), and the disturbance of the steam bottom will be limited to an area 3 ft
around the perimeter of the bent. The existing footing below streambed will be left
in place to avoid additional streambed disturbance.
7. The temporary causeways used for the project were designed to result in the least
amount of rock fill entering the river while providing sufficient area to accomplish
the construction and demolition. The causeways will be constructed with pipes to
maintain linear flow of the river by passing water through the causeways. The
construction of the causeways will follow a phasing plan so that not all causeways
needed for construction and demolition are in the river at the same time, minimizing
impacts to the flow of the river. The use of Jersey-type or similar barrier devices
will be installed around the perimeter of the causeways to help contain the stone
used to construct the causeways.
8. The use of explosives will not be allowed.
9. Saw slurry must be contained by approved vacuum methods.
Additional Conservation Measures
1. In order to avoid and minimize environmental impacts associated with these
projects, all standard procedures and measures, including the NCDOT's BMP for
Construction and Maintenance Activities and the TVA's Water Management
Standard Conditions will be strictly enforced during the project. Provisions to
preclude contamination by toxic substances during the project will also be strictly
enforced.
2. The NCDOT proposes to relocate all native mussels, including the Appalachian
elktoe, from the footprints and extending downstream 262 ft (80 m) and upstream
66 ft (20 m) of the two bridge replacement projects. The procedure for the
relocation is detailed in the BA. The relocation procedure within the BA provides a
plan that relocates freshwater mussels in such a way as to reduce stress and
minimize the risk of injury while the species are in transit. If at any time during the
relocation it is determined that these procedures are not meeting the stated
objectives, more stringent. methods .may be developed, in cooperation with the
NCWRC and the Service, to ensure that the mussels are relocated successfully.
During August 2005 the NCDOT, NCWRC, Catena Group, and Service worked
together to choose a suitable relocation site. It was decided that the mussels from
both bridge sites would be moved to suitable habitat within the upstream limits of
the Appalachian elktoe's distribution. Concentrating mussels in a location within
the upper limits of its distribution, where numbers are currently very low, may help
facilitate the continued up-river recruitment trend of the species. The most suitable
site was determined to be on the North Toe River, between Penland and Boonford,
at approximately river mile 25.5. The relocation site will be monitored for the
survival of relocated mussels and the movement of mussels a month after they have
14

been removed from the defined salvage areas. The relocation site will then be
monitored for recovery, survival (of recovered mussels), movement, and growth of
mussels once a year for 5 years after the project is constructed.
The NCDOT has initiated a watershed search for potential riparian properties within
the Toe River. The NCDOT has investigated approximately five sites consisting of
opportunities for 100-ft riparian buffer protection and/or restoration. The NCDOT
has committed to purchase (for protection and/or restoration) at least 3,000 linear ft
of these riparian buffers sites. Riparian buffers will be purchased to offset
unavoidable impacts on the Appalachian elktoe population associated with the
bridge construction and demolition.
4. The NCDOT proposes to monitor the river channel and banks at sites upstream, at
the construction sites, and downstream to determine changes in habitat resulting
from activities at these sites. If any problems with regard to stream stability are
detected during the monitoring, the NCDOT has proposed to attempt to correct the
problems. This monitoring will also help evaluate the impacts of construction on
habitat in the Toe River.
5. The NCDOT has developed erosion-control measures for these two projects
specifically to protect the Appalachian elktoe and its habitat. These measures are
listed in the "Conservation Measures for Bridge Design" section of this Opinion. In
addition to these erosion-control measures, an inspection of the erosion-control
devices will be conducted on a daily basis by the Construction Project Inspector
positioned in the District Office in which the project occurs. The Roadside
Environmental Branch of the NCDOT also has Area Field Operations Engineers
who will perform compliance inspections of the erosion-control devices a minimum
of twice a month during the life of a project. In addition to these levels of
inspection, an environmental specialist with the NCDOT Office of Natural
Environment's Biological Surveys Unit will perform periodic site inspections of the
erosion-control measures at the respective construction sites. This person will also
be making qualitative assessments of the Toe River habitat at the construction sites.
These visits will be unannounced and directly in relationship to rain events
whenever possible.
6. The NCDOT Project Development and Environmental Analysis Branch and the
Service will be invited to the preconstruction conference to discuss with the
contractor the provisions of this Opinion. Prior to construction the contractor will
be required to give. notification of the construction initiation date to the Service,
NCWRC, and TVA.

II. STATUS OF THE SPECIES AND ITS CRITICAL HABITAT
A. Species Description, Life History, and Critical Habitat Description
The Appalachian elktoe has a thin, but not fragile, kidney-shaped shell, reaching up to
about 3.2 inches (in.) in length, 1.4 in. in height, and 1 in. in width. Juveniles generally
have ayellowish-brown periostracum (outer shell surface), while the periostracum of
the adults is usually dark brown to greenish-black in color. Although rays are
prominent on some shells, particularly in the posterior portion of the shell, many
individuals have only obscure greenish rays.. The shell nacre (inside shell surface) is
shiny, often white to bluish-white, changing to a salmon, pinkish, or brownish color in
the central and beak cavity portions of the shell; some specimens may be marked with
irregular brownish blotches.
The Appalachian elktoe has been reported from relatively shallow, medium-sized
creeks and rivers with cool, clean, well-oxygenated, moderate- to fast-flowing water.
The species is most often found in riffles, runs, and shallow flowing pools with stable,
relatively silt-free, coarse sand and gravel substrate associated with cobble, boulders,
and/or bedrock (Gordon 1991; Service 1994, 1996, 2002}. Stability of the substrate
appears to be critical to the Appalachian elktoe, and the species is seldom found in
stream reaches with accumulations of silt or shifting sand, gravel, or cobble (Service
2002). Individual specimens that have been encountered in these areas are believed to
have been scoured out of upstream areas during periods of heavy rain and have not
been found on subsequent surveys (Service 2002).
.Like other freshwater mussels, the Appalachian elktoe feeds by filtering food particles
from the water column. The specific food habits of the species are unknown, but other
freshwater mussels have been documented to feed on detritus (decaying organic
matter), diatoms (various minute algae) and other algae and phytoplankton
(microscopic floating aquatic plants), and zooplankton (microscopic floating aquatic
animals). The reproductive cycle of the Appalachian elktoe is similar to that of other
native freshwater mussels. Males release sperm into the water column, and the sperm
are then taken in by the females through their siphons during feeding .and respiration.
The females retain the fertilized eggs in their gills until the larvae (glochidia) fully
develop. The mussel glochidia are released into the water and, within a few days, must
attach to the appropriate species offish, which they then parasitize for a short time
while they develop into juvenile mussels. They then detach from their fish host and
sink to the stream bottom where they continue to develop, provided they land in a
suitable substrate with the correct water conditions. The banded sculpin (Cottus
carolinae) was identified as a host species for glochidia of the Appalachian elktoe at
the time the elktoe was listed, and the mottled sculpin (C. bairdi) was identified as a
host species soon after the listing (Service 2002). Dr. Jim Layzer (Tennessee
Technological University, unpublished data) has recently identified eight additional
species offish that successfully transformed glochidia of the Appalachian elktoe into
juveniles under laboratory condition. These eight species include the wounded darter
(Etheostoma vulneratum), greenfin darter (Etlieostoma chlorobranchium), greenside
16

darter (Etheostoma blenniodes), river chub (Nocomis micropogon), northern hogsucker
(Hypentilum rrigracans), central stoneroller (Campostoma anomalzsrn), longnose dace
(Rhinichthys cataractae), and rosyside dace (Clinostomus fisnduloides). The life span
and many other aspects of the Appalachian elktoe's life history are currently unknown.
Critical habitat was designated for the Appalachian elktoe in 2002 (Service 2002). The
areas designated as critical habitat for the Appalachian elktoe total approximately
144.3 miles of various segments of rivers in North Carolina and one river in Tennessee.
Critical habitat identifies specific areas that are essential to the conservation of a listed
species and that may require special management considerations or protection. Section
7(a)(2) of the Act requires that each federal agency shall, in consultation with the
Service, ensure that any action authorized, funded, or carried out by such agency is not
likely to jeopardize the continued existence of an endangered or threatened species or
result in the destruction or adverse modification of critical habitat.
The following constituent elements are part of the critical habitat designation and are
essential to the conservation of the Appalachian elktoe:
1. Permanent, flowing, cool, clean water;
2. Geomorphically stable stream channels and banks;
3. Pool, riffle, and run sequences within the channel;
4. Stable sand, gravel, cobble, and boulder or bedrock substrates with no more than
low amounts of fine sediment;
5. Moderate to high stream gradient;
6. Periodic natural flooding; and
7. Fish hosts, with adequate living, foraging, and spawning areas for them.
In the Nolichucky River subbasin, critical habitat is designated for the Appalachian
elktoe in the main stem of the Nolichucky River, Cane River, Toe River, South Toe
River, and North Toe River.
B. Status and Distribution
The Appalachian elktoe is known only from the mountain streams of western North
Carolina and eastern Tennessee.. Although the complete historical range of the
Appalachian elktoe is unknown, available information suggests that the species once
lived in the majority of the rivers and larger creeks of the upper Tennessee River
system in North Carolina, with the possible exception of the Hiawassee and Watauga
River systems (the species has not been recorded from either of these river systems). In
17

Tennessee, the species is known only from its present range in the main stem of the
Nolichucky River.
Currently, the Appalachian elktoe has a very fragmented, relict distribution. The
species still survives in scattered pockets of suitable habitat in portions of the Little
Tennessee River system, Pigeon River system, Mills River, and Little River in North
Carolina and the Nolichucky River system in North Carolina and Tennessee.
Little Tennessee River Subbasin - In the Little Tennessee River system in North
Carolina, populations survive in the reach of the main stem of the Little Tennessee
River, between the city of Franklin and Fontana Reservoir, in Swain and Macon
Counties (McGrath 1999; Service 1994, 1996, 2002), and in scattered reaches of the
main stem of the Tuckasegee River in Jackson and Swain Counties (McGrath 1998;
Tim Savidge, NCDOT, personal communication, 2001; Service 2002), from below the
town of Cuilowhee downstream to Bryson Ciry. Monitoring by the NCWRC of the
Appalachian elktoe population in the Little Tennessee River over the last couple of
years has revealed that the population is apparently declining. A single live individual
and one shell were recorded in 2000 from the Cheoah River, below Santeetlah Lake, in
Graham County (Service 2002). Biologists with the NCDOT, U.S. Forest Service, and
the Service have recorded up to 11 live Appalachian elktoes from the Cheoah River,
below Santeetlah Dam, during surveys of portions of the river in 2002, 2003, 2004, and
2005.
French Broad River Subbasin - In the Pigeon River system in North Carolina, a small
population of the Appalachian elktoe occurs in small scattered sites in the West Fork
Pigeon River and in the main stem of the Pigeon River, above Canton, in Haywood
County (McGrath 1999, Service 2002). The Little River (upper French Broad River
system) population of the species, in Transylvania County, North Carolina (Service
2002), is restricted to small scattered pockets of suitable habitat downstream of Cascade
Lake. In the Mills River, Henderson County, North Carolina, the Appalachian elktoe
occurs in a short reach of the .river, from just above the Highway 280 bridge (Savidge,
Catena Group, personal communication, 2003) to about 1 mile below the bridge (Jeff
Simmons, NCWRC, personal communication, 2004). In addition, NCWRC biologists
have recently discovered a few individuals of the species at a site in the main stem of
the French Broad River, below the mouth of the Little River (Steve Fraley, NCWRC,
personal communication, 2005).
NolichuckYRiver Subbasin - In the Nolichucky River system, the Appalachian elktoe
survives in scattered areas of suitable habitat in the Toe River, Yancey and Mitchell
Counties, North Carolina (McGrath 1996, 1999; Service 1994, 1996); the Cane River,
Yancey County, North Carolina (McGrath 1997; Service 1994, 1996); and the main
stem of the Nolichucky River, Yancey and Mitchell Counties, North Carolina,
extending downstream to the vicinity of Erwin, Unicoi County, Tennessee (Service
1944, 1996, 2002). A cooperative and comprehensive mussel survey effort was
undertaken between 2000 and 2003 by the NCWRC, NCDOT, NCNHP, and Service
throughout the upper Nolichucky River system in Yancey, Mitchell, and Avery
18

Counties, North Carolina. Given that many areas in the Nolichucky River system had
not been surveyed since the 1990s, the primary goal for these surveys was reassessment
of the Appalachian elktoe's population status. The survey efforts indicate that suitable
habitat within at least 73 miles of stream in the Nolichucky River system is presently
occupied by the Appalachian elktoe, an apparent 15-mile increase from reported
occupied habitat prior to 2000 (Fraley and Simmons 2004). These surveys also indicate
that this population appears to be growing in numbers as well. Sites where mussels
were found during 2000 and 2003 produced higher catch per unit effort (CPUE} than
the nearest sites sampled prior to 2000 (Fraley and Simmons 2004). However, the
available habitat in the subbasin is a limiting factor; therefore, the Appalachian elktoe is
not evenly dispersed throughout the 15-mile increase in the subbasin.
During August and September of 2004, significant flooding from Hurricanes Frances
and Ivan occurred in the Nolichucky River drainage. The NCWRC surveyed sites in
the Nolichucky River drainage for federally listed and state-listed mussels after the
hurricanes and compared the results to survey results prior to the hurricanes. As stated
previously, based on the results in 2000 and 2003, prior to the 2004 floods,
Appalachian elktoe populations in the Nolichucky subbasin were found to be increasing
in abundance and expanding their range. The survey results after the floods of 2004
indicate that recovery was. set back to some degree based on reduced CPiTE results;
however, Appalachian elktoes were found throughout most of the occupied range
known in 2003, which illustrates the resilience of the species to periodic hydraulic
disturbance, especially in a system, such as the Nolichucky River subbasin, that is more
prone to habitat disturbance from floods. Currently, the Nolichucky population appears
to be a relatively large (at least in terms of spatial distribution) metapopulation that is
more or .less contiguous, with at least the opportunity for some level of gene flow
throughout the subbasin (Fraley and Simmons 2006).
Extirpated Sites -Historically, the species has been recorded from Tulula Creek
(Tennessee River drainage), the main stem of the French. Broad River at Asheville, and
the Swannanoa River (French Broad River system) (Clarke 1981), but it has apparently
been eliminated (except from a small section of the main stem. of the French Broad
River at the confluence of the Little River) from these streams (Service 1994, 1996).
There is also a .historical record of the Appalachian ellctoe from the North Fork Holston
River in Tennessee (S. S. Haldeman collection); however, this record is believed to
represent a mislabeled locality (Gordon 1991). If the historical record for the species in
the North Fork Holston River was accurate, the species has apparently been eliminated
from this river as well.
Available information indicates that several factors have contributed to the decline and
loss of populations of the Appalachian elktoe and threaten the remaining populations.
These factors include pollutants in wastewater discharges (sewage treatment plants and
industrial discharges); habitat loss and alteration associated with impoundments,
channelization, and dredging operations; and the runoff of silt, fertilizers, pesticides,
and other pollutants from land-disturbing activities that were implemented without
adequate measures to control erosion and/or storm water (Service 1994, 1996).
19

Mussels are known to be sensitive to numerous pollutants, including, but not limited to,
a wide variety of heavy metals, high concentrations of nutrients, ammonia, and
chlorine-pollutants commonly found in many domestic and industrial effluents
(Havlik and Marking 1987). In the early 1900s, Ortmann (1909) noted that the
disappearance of unionids (mussels) is the first and most reliable indicator of stream
pollution. Keller and Zam (1991.) concluded that mussels are more sensitive to metals
than commonly tested fish and aquatic insects. The life cycle of native mussels makes
the reproductive stages especially vulnerable to pesticides and other pollutants (Fuller
1974, Gardner et al. 1976, Ingram 1957, Stein 1971). Effluent from sewage treatment
facilities can be a significant source of pollution that can severely affect the diversity
and abundance of aquatic mollusks. The toxicity of chlorinated sewage effluents to
aquatic life is well-documented (Bellanca and Bailey 1977, Brungs 1976, Goudreau
et al. 1988, Tsai 1975), and mussel glochidia (larvae) rank among the most sensitive
invertebrates in their tolerance of the toxicants present in sewage effluents (Goudreau
et al. 1988). Goudreau et al. (1988) found that the recovery of mussel populations may
not occur for up to 2 miles below the discharge points of chlorinated sewage effluent.
Land-clearing and disturbance activities carried out without proper sedimentation and
storm-water control pose a significant threat to the Appalachian elktoe and other
freshwater mussels. Mussels are sedentary and are not able to move long distances to
more suitable areas in response to heavy silt loads. Natural sedimentation resulting
from seasonal storm. events probably does not significantly affect mussels, but human
activities often create excessively heavy silt loads that can have severe effects on
mussels and other aquatic organisms. Siltation has been documented to adversely
affect native freshwater mussels, both directly and indirectly (Aldridge et al. 1987, Ellis
1936, Kat 1982, Marking and Bills 1979}. Siltation degrades water and substrate
quality, limiting the available habitat for freshwater mussels (and their fish hosts),
thereby limiting their distribution and potential for the expansion. and maintenance of
their populations; irritates and clogs the gills of filter-feeding mussels, resulting in
reduced feeding and respiration; smothers mussels if sufficient accumulation occurs;
and increases the potential exposure of the mussels to other pollutants. Ellis (1936)
found that less than 1 in. of sediment deposition caused high mortality in most mussel
species. Sediment accumulations that are less than lethal to adults may adversely affect
or prevent the recruitment of juvenile mussels into the population. Also, sediment
loading in rivers and streams during periods of high discharge is abrasive to mussel
shells. Erosion of the outer shell allows acids to reach and corrode underlying layers
that are composed primarily of calcium, which dissolves under acid conditions
(Harman 1974).
The effects of impoundments on mussels are also well-documented. For the most part,
lakes do not occur naturally in western North Carolina and eastern Tennessee (most of
them are man-made), and the Appalachian elktoe, like the majority of our other native
mussels, fish, and other aquatic species in these areas, is adapted to stream conditions
(flowing, highly oxygenated water and coarse sand and gravel bottoms). Dams change
the habitat from flowing to still water. Water depth increases, flow decreases, and silt
accumulates on the bottom (ilVilliams et al. 1.992), altering the quality and stability of
20

the remaining stream reaches by affecting water flow regimes, velocities, temperature,
and chemistry. Dams that operate by releasing cold water from near the bottom of the
reservoirs lower the water temperature downstream, changing downstream reaches
from warm- or cool-water streams to cold-water streams and affecting their suitability
for many of the native species historically inhabiting these stream reaches (Miller et al.
1984, Layzer et al. 1993). The effects of impoundments result. in changes in fish
communities (fish host species may be eliminated) (Brimm 1991) and in .mussel
communities (species requiring clean gravel and sand substrates are eliminated) (Bates
1962). In addition, dams result in the fragmentation and isolation of populations of
species and act as effective barriers to the natural upstream and downstream expansion
or recruitment of mussel and fish species.
The information available demonstrates that habitat deterioration resulting from
sedimentation and pollution from numerous point and nonpoint sources, when
combined with the effects of other factors (including habitat destruction, alteration, and
fragmentation resulting from impoundments, channelization projects, etc.), has played a
significant role in the decline of the Appalachian elktoe. We believe this is particularly
true of the extirpation of the Appalachian elktoe from the Swannanoa River, most of the
French Broad River, and long reaches of the Pigeon, upper Little River, and upper
Little Tennessee River systems. We believe these factors also have contributed to the
extirpation of the species from parts of the upper Tuckasegee River, Cheoah River, and
Tulula Creek, though the effects of impoundments are believed to have played an even
more significant role in the loss of the species in the upper reaches of these streams.
The most immediate threats to the remaining populations of the Appalachian elktoe are
associated with sedimentation and other pollutants (i.e,, fertilizers, pesticides, heavy
metals, oil, salts, organic wastes, etc.) from nonpoint sources. Much of the Nolichucky
.River in North Carolina contains heavy loads of sediment, primarily from past
land-disturbing .activities within its watershed, and suitable habitat for the Appalachian
elktoe appears to be very limited in this river system. The species has not been found
in the Nolichucky River system in substrates with. accumulations of silt and shifting
sand; it is restricted to small scattered pockets of stable, relatively clean, and gravelly
substrates. The same is true of the other surviving populations of the species.
C. Analysis of the Species and Critical Habitat Likely to be Affected
Species - NCDOT biologists conducted mussel surveys at the two bridge sites on
July 24, 1996. The surveys were conducted from a point approximately 1,31.2 ft
(400 m) downstream to 328 ft (100 m) upstream of the existing bridges. A total of five
Appalachian elktoes and two wavy-rayed lampmussels were discovered in
2.5 person-hours of survey time at the B-1'443 bridge site, totaling a Catch Per Unit
Effort {CPUE) of 2 per hour for the Appalachian elktoe_ At the B-2848 bridge site,
seven Appalachian elktoes and two wavy-rayed lampmussels were found in
3 person-hours of survey time, totaling a CPUE of 2.33 per hour for the Appalachian
elktoe.
21

During the cooperative and comprehensive mussel survey efforts mentioned previously,
another mussel survey was conducted at the two bridge sites on September 9, 2002. A
total of 11 Appalachian ellctoes and 2 wavy-rayed lampmussels were discovered at the
B-1443 site in 4 person-hours of survey time, totaling a CPUE of 2.75 per hour for the
Appalachian elktoe. At the B-2848 site, 15 Appalachian elktoes and 2 wavy-rayed
lampmussels were found in 3.5 person-hours of survey time, totaling a CPUE of 4.28
per hour for the Appalachian elktoe. The survey limits during these surveys were
confined to the areas immediately under the existing bridges because previous surveys
had documented the species at these sites. The highest CPUE for the Appalachian
elktoe during the comprehensive surveys in the basin was i 6 per hour (total of
96 individuals); this occurred at a site in the South Toe River (Fraley and Simmons
2004).
Mussel surveys were also conducted in 2002 by Service, NCWRC, and NCDOT
personnel in habitats in close proximity to the existing bridges. The purpose of these
surveys was to identify potential relocation sites., Neither the exact locations nor the
results of those surveys were recorded.
Densities of Appalachian elktoes vary, depending on many factors that cause their
distribution pattern to be scattered and difficult to generalize. Based on surveys for
Appalachian elktoes from other drainages, the number below the surface is highly
variable and dependent on the substrate. In general, mussels can be very difficult to
locate in the substrate, and most mussel surveys detect only those specimens located at
or on the surface of the substrate. It is likely that additional mussels were present in the
survey areas which were overlooked or were not visible on the surface of the stream
bottom. It is also potentially likely that fewer mussels are currently present at the site
because of impacts from the 2004 hurricanes. Therefore, accurate estimates of the total
number of Appalachian elktoes that will be impacted (both above and below the surface
of the stream bottom) are not possible, but the numbers are likely different from those
recorded during the surveys.
Critical Habitat -Given that the Appalachian elktoe occurs within the area of the two
bridges and Nolichucky River subbasin, it appears that the constituent elements
.necessary for critical habitat are present within the project area as well as portions of
the Cane River, Toe River, and North Toe River. Following is a brief description of the
status of the constituent elements within the project area:
1. Permanent, flowing, cool, clean water -There is variation in stream flow within
critical habitat; however, there is always permanent flowing water. Based on the
DWQ's bioassessrnents of benthic macroinvertebrate and fish sampling, the water
appears to be cool and clean enough to sustain a population of the Appalachian
elktoe.
2. Geomorphically stable stream channels and banks -Overall, the stream channel and
stream banks appear to be stable at the two bridge sites, as evidenced by the
22

presence of vegetation on the river banks (trees, shrubs, and herbaceous plants) and
an abundance of benthic organisms in the substrate.
3. Pool, riffle, and run sequences within the channel -The Cane River, Toe River, and
North Toe River have natural pool, riffle, and run sequences, varied by the local
stream gradient and bedrock influence. There is a natural pool, riffle, and run
sequence at both bridge sites.
4. Stable sand, gavel, cobble, and boulder or bedrock substrates with no more than
low amounts of fine sediment -The habitat within the project area at the bridge sites
consists primarily of bedrock, with small patches of gravel and course sand
providing microhabitat for the Appalachian elktoe. At B-2848 there is more
favorable habitat downstream of the bridge, consisting of an island of gravel and
course sand and numerous Appalachian elktoes.
S. Moderate to high stream gradient -The Cane River, Toe River, and North Toe
River are characterized as high stream gradient. Some portions of these reaches in
the alluvial floodplain have some moderate stream gradient, but nowhere can the
stream be characterized as low gradient.
6. Periodic natural flooding -Natural peak events occur throughout the Nolichucky
River subbasin.
7. Fish hosts, with adequate living foragingand spawning areas for them -Recent
sampling by the NCWRC and TVA identified fairly diverse fish communities,
including many of the ,potential host fishes for the Appalachian elktoe in the Cane
River, Toe River, .and North Toe River.
III. ENVIRONMENTAL BASELINE
Under section ?(a)(2) of the Act, when considering the "effects of the action" on federally
listed species, we are required to take into consideration the environmental baseline. The
environmental baseline includes past and ongoing natural factors and the past and present
impacts of all federal, state, or private actions and other activities in the action area
(50 CFR 402.02), including federal actions in the area that have already undergone
section 7 consultation, and the impacts of state or private actions that are contemporaneous
with the consultation in process. The environmental baseline for this Opinion considers all
projects approved prior to the initiation of formal consultation.
A. Status of the Species Within the Action Area
Survey efforts between 2000 and 2003 indicate that suitable habitat within at least
73 miles of stream in the Nolichucky River system are presently occupied by the
Appalachian elktoe; an apparent 1 S-mile increase from reported occupied habitat prior
to 2000 (Fraley and Simmons 2004). These surveys also indicate that this population
23

appears to be growing in numbers as well. Sites where mussels were found during
2000 and 2003 produced higher CPUEs than the nearest sites sampled prior to 2000
(Fraley and Sirnrnons 2004). However, the available habitat in the subbasin is a
limiting factor; therefore, Appalachian elktoes are not evenly dispersed throughout the
73-mile range within the subbasin. The NCWRC's sampling efforts after the floods of
2004 indicate that, since the last survey efforts in 2000 and 2003, recovery was set back
to some degree based on reduced CPUE results; however, Appalachian elktoes were
found throughout most of the occupied range known in 2003.
As stated previously, the 2002 mussel surveys at the bridge sites indicate that at least
26 individual Appalachian elktoes occur within project area. The CPUE for the bridge
sites was 2.75 per hour for the B-1443 site and 4.28 per hour for the B-2848 site. As
part of the NCWRC's continued monitoring efforts of state-listed and federally listed
mussels, in 2002 and 2003 the NCWRC surveyed six sites in the Toe River for the
Appalachian elktoe. Three of the six sites had higher CPUEs than the highest CPUE at
the bridge sites, and four of the sites had higher CPUEs than the lowest CPUE at the
bridge sites (Fraley, NCWRC, personal communication and unpublished data, 2006).
This indicates that the mussel population at the bridge sites is average to below average
for the Toe River. Further, while 26 individual Appalachian elktoes at the site will be
relocated {and potentially lost), there are several other sites within the Toe River that
support equal or greater numbers of the elktoe. Therefore, that population should be
able~to recover from this loss, and the conservation measures developed by the NCDOT
should minimize the loss of Appalachian elktoes.
The BA determined the direct and indirect impacts occurring within 1,312 ft (400 m)
downstream and 328 ft (100 m) upstream of the existing and proposed bridge sites.
Considering the placement of the bridges, the total potential amount of impact at the
B-1443 site is 1,820 ft (555 m) and 1,689 ft (515 m) at the B-2848 site. Therefore
approximately 0.66 mile of the Toe River could potentially be directly or indirectly
impacted by construction and demolition activities from the project. Therefore, within
the 73-mile range of the Appalachian elktoe in the Nolichucky River system, the bridge
replacement projects could have an impact on 0.9 percent of this potential habitat.
The constituent elements necessary for critical habitat are present within the project
area and could be affected by the. construction and demolition of the projects. The
following is a list of the constituent elements that may be impacted by the project:
1. Permanent, flowing, cool, clean water -There could be impacts to the amount of
sediment that enters the river from the demolition process..
2. Geomorphically stable stream channels and banks -The stream channel could be
temporarily impacted during the construction of the causeways and bridge piers.
3. Pool, riffle, and run sequences within the channel -The flow of the river could
change while the temporary causeways are in place.
24

4. Stable sand, gavel, cobble, and boulder or bedrock substrates with no more than
low amounts of fine sediment - As stated previously, the amount of sediment could
increase during the bridge demolition process.
While there could be impacts to critical habitat, most of these impacts should be
temporary, and the conservation measures developed by the NCDOT should minimize
all effects.
B. Factors Affecting the Species' Environment Within the Action Area
Some residential development and agricultural practices have impacted the aquatic
habitat in the action area, particularly the riparian habitat. Because riparian areas have
been cleared of trees and other woody vegetation and rock has been placed on the river
banks, high-water events have resulted in bank erosion and failure at several areas in
the Nolichucky subbasin. The poor condition of the riparian habitat also likely leads to
excessive runoff from adjacent agriculture fields that contain not only silt but also the
fertilizers and pesticides used in those fields.
Two bridges along the Toe River--B-2081 and B-3089--have been replaced within the
last 10 years. No mussels were discovered within the project area of these bridges nor
was critical habitat listed at that time; therefore, the projects were constructed in a
manner that avoided adverse effects to the Appalachian elktoe. During August and
September of 2004, significant flooding occurred in the 1Volichucky .River drainage.
The Natural Resources Conservation Service (NRCS) proposed the implementation of
the Emergency Watershed Protection. (EWP) program to restore areas impacted by the
flooding. In December 2005 we issued a biological opinion to the NRCS for
implementation of the EWP program. That biological opinion assessed the direct and
indirect impacts to 3,325 linear ft of stream within the Nolichucky River subbasin and
any additional indirect impacts to 1,312 ft (400 m) downstream of each of the
18 individual :restoration project "footprints." Other federal actions proposed for the
upper Nolichucky River basin include widening and improving Highway 19E for about
29 miles. This will include the widening/extension and construction of several stream
crossing structures within the Nolichucky River subbasin (94 crossings total) and will
require a 404 permit (from the U.S. Army Corps of Engineers) for the filling of
wetlands and alteration of stream channels associated with development of the
proposed "Communities of Penland" along the North Toe River. We do not have any
information concerning any additional federal actions ongoing or proposed for the
action area at the present time.
IV EFFECTS OF THE ACTION
Under section 7(a)(2) of the Act, "effects of the action" refers to the direct .and indirect
effects of an action on the species or critical habitat, together with the effects of other
activities that are interrelated or interdependent with that action.. The federal agency is
responsible for analyzing these effects. The effects of the proposed action are added to the
25

environmental baseline to determine the future baseline, which serves as the basis for the
determination in this Opinion. Should the effects of the federal action result in a situation
that would jeopardize the continued existence of the species, we may propose reasonable
and prudent alternatives that the federal agency can take to avoid a violation of section
7(a)(2). The discussion that follows is our evaluation of the anticipated direct and indirect
effects of replacing the subject two bridges. Indirect effects are those caused by the
proposed action that occur later in time but are still reasonably certain to occur (50 CFR
402.02).
A. Factors to be Considered
Proximity of the Action -Based on the 2002 mussel survey conducted by the NCDOT,
at least 26 individuals of the Appalachian elktoe occur in the vicinity of the existing
bridges. Although measures to avoid and minimize impacts to the Toe River and the
Appalachian elktoe are included in the project plans, implementation of these projects
will result in unavoidable impacts to the river habitat and to individual mussels.
However, several other sites within the 73 miles of occupied river reaches support
equal or greater numbers of individuals (Fraley, NCWRC, personal communication and
unpublished data, 2006).
Nature of the Effect - In-stream habitat will be impacted permanently by the
construction of the piers within the river channel, 57 ft2 for B-1443 and 32 ftz for
B-2848. Suitable in-stream habitat at both construction sites will also be affected for
the duration of the construction and demolition and likely'for some period after
completion of the projects. Portions of the habitat may be impacted permanently by the
construction and use of the causeways. A small portion of the riparian area at both sites
may be cleared for equipment access and could result in temporary increases in water
temperature at each location until reforestation can occur.
Disturbance Duration, Frequency, and Intensity -Disturbance to the riverbed will occur
over a relatively short period of time from the construction of the bridge piers. It will
take approximately 3 weeks to install each bent. However, the disturbance to the
river's flow pattern at the piers will exist throughout the life of the bridges. The
causeways for construction and demolition will be in place for the length of time
needed to construct and demolish the bridges; therefore, the disturbance to the riverbed
associated with the causeways will be over an extended period of time. Although there
will be direct impacts to the riverbed associated with the causeways, the construction of
the causeways will be phased to limit the amount of causeway in the river at any one
time, and only the causeways needed for an activity will be in place during that activity
and will be removed when the action is completed. The causeways will be constructed
with clean stone and pipes so that the river can flow through, not just over, the
causeways. However, there will still be impacts to the hydrology of the river both
upstream and downstream ofthe-causeways.
26

S. Analyses of Effects of the Action
Potential Beneficial Effects
The construction and demolition of the existing bridges have some negative impacts but
also have some long-term beneficial effects. Specifically, the NCDOT has described
the following beneficial effects that could result from these projects:
Reduction of direct storm-water runoff. Storm water from the existing bridges
enters the river directly from the bridge decks. The new bridges will collect and
direct storm water. into catch basins, and the storm water will then flow through a
vegetated buffer before entering the river. Storm water coming off the approaching
roadways at the bridge locations will be managed in a similar manner. The
elimination/reduction of runoff into the Toe River may result in localized
improvement of water quality and potentially have a beneficial effect on the
Appalachian elktoe.
2. Reduction in number of bents in the main river channel. The existing B-1443
bridge has two piers within the river channel totaling an area of 151.2 ft2. The new
bridge construction will require the placement of two piers in the river, which will
result in 57 ft2 of fill. The existing B-2848 bridge has three piers within the river
channel totaling an area of 349 ft2. The new bridge construction will require one
bent for construction, consisting of two drilled piers totaling 32.0 ft2 of fill. Given
that bents in the river trap debris during high flows and can change the hydraulics in
the immediate vicinity of the structure (causing scour and deposition), the reduction
in the number of piers in the Toe River is expected to reduce the bridges' effects on
stream-flow patterns at the respective bridge sites.
Direct Effects -Actions that may result in direct impacts include the construction of
causeways for the construction of new structures and the demolition of existing
structures, land clearing for access, potential toxic spills, the removal of causeways
after construction, and the demolition and removal of existing bridge structures. All of
these activities have the potential to .kill or injure mussels, either by crushing them;
poisoning them with the release of some toxic substance; or causing siltation, which
may suffocate them. These actions may result in direct harm to individuals or negative
changes in currently suitable habitat.
Substrate Disturbance and/or Habitat Loss
Project B-1443: The construction of this new bridge will require the placement of two
piers in the river, which will result in 57 ft2 of permanent fill. This will be a 94.2-ft2
reduction from the existing structure, which has two bents totaling 1.51.2 ft`' of fill in the
river. Rock causeways will be required to construct the new bridge and demolish the
existing bridge. The temporary construction/demolition causeways used for the project
are designed to result in the least amount of rock fill in the river while providing
sufficient area. to accomplish the construction and demolition. The causeways will be
27

constructed with pipes to maintain linear flow of the river by passing water through the
causeways. The construction of the causeways will follow a phasing plan to minimize
impacts to the flow of the river; at the narrowest point, 50 percent of the river will be
open. To construct the piers for the new bridge and demolish the existing bridge, the
causeways will result in 4,972 ft2 and 3,993.4 ft'` of temporary rock fill in the river,
respectively. There also will be a minimal amount of temporary rock fill associated
with the temporary support frames that will be placed in the river under each arch to
support the bridge during demolition.
Project B-2848: The construction of this new bridge will require the placement of one
bent in the river, consisting of two drilled piers, which will result in 32.0 ft2 of
permanent fill. This will be a 317-ft2 reduction from the existing structure, which has
three piers totaling 349 ft2 of fill in the river. Rock causeways will also be required for
construction and demolition of this project. The causeways for this project follow the
design standards listed for B-1443. The construction of the causeways will follow a
phasing plan to minimize impacts to the flow of the river; at the narrowest point,
52 percent of the river will be open. To construct the piers for the new bridge and
demolish the existing bridge, the causeways will result in 15,551 ft2 and 1,786 ft2 of
temporary rock fill in the river, respectively. There also will be a minimal amount of
temporary rock fill associated with the temporary support frames that will be placed in
the river under each arch to support the bridge during demolition.
There will be a combined permanent loss of 89.0 ft2 of stream habitat at the two project
sites. There will also be a combined temporary loss of stream habitat from the
construction/demolition causeways of 26,302 ft2. Based on the surveys conducted in
2002 by the NCDOT, it is likely that at least 26 individual Appalachian elktoe mussels
will be impacted by the project. The NCDOT is proposing to remove individuals from
the impact sites and relocate them (see the "Additional Conservation Measures" in the
"Conservation Measures" section of this Opinion). While the causeways will be placed
in the river only temporarily, it is difficult to predict if the impacts to the streambed will
permanently or temporarily impact habitat and mussel recruitment to the sites. Given
that the habitat at the impact sites consists primarily of bedrock, a reduction in suitable
habitat by substrate compaction from the causeways is less likely.
Impacts from Sedimentation
Because of the topography and the erodible nature of the soils in the project area (fine
loamy soils with moderate erodibility), project construction has the potential to result in
sedimentation in the Toe River. To minimize the potential for sedimentation, the
NCDOT has developed specific erosion-control measures for this project that are
designed to protect environmentally sensitive areas (see the "Conservation Measures"
section of this Opinion). The primary concerns for sedimentation entering the river are
during the removal of the earth-filled material in bridge B-2848 and the demolition of
both bridges. The NCDOT has provided a plan for the removal of the earth-filled
material as well as plans for stabilizing the bridges during demolition, reducing the
likelihood that sediment will enter the river as a result of these actions.
28

Impacts from Changes in Hydrology
The temporary causeways proposed at both project sites will narrow the channel and
will alter the hydrology, resulting in localized changes in flow patterns at the respective
sites. This change in hydrology and any associated scour could result in the loss or
displacement of mussels. However, the change in hydrology will be temporary, during
the life of the respective causeways, and the design of the causeways (allowing for flow
through the causeways) should minimize the impacts to hydrology and associated
impacts. The NCDOT has proposed to monitor the riverbed and stream-bank stability
before, during, and after construction at both bridge sites. If any problems with regard
to stream stability are detected during the monitoring, the NCDOT has proposed to
attempt to correct the problems.
Impacts to Fish Hosts
In addition to the potential changes in hydrology as a result of the causeways, there is
the potential for the causeways to act as a barrier to fish migration. The disruption of
fish migrations could indirectly impact the Appalachian elktoe if the fish that are
disturbed serve as fish hosts for the elktoe. While temporary disruptions to fish
migration may occur during construction of the causeways, the following design factors
should reduce the long-term effects of the causeways on f sh migration: the causeways
will be temporary structures in'the river, at least 50 percent of the channel will be
unrestricted by the causeways at any given time, and the causeways are designed to
allow for linear flow. Given these design features, the causeways are not expected to
have a significant impact, if any, on the natural migration of fish species and therefore
should not impact the life cycle or distribution of the Appalachian elktoe in the Toe
River.
,Indirect Effects -Indirect effects are defined as those that are caused by the proposed
action and are later in time but are still reasonably certain to occur (50 CFR 402.02).
Indirect effects to the Appalachian elktoe may include permanent changes in channel
substrate or stability that adversely affect the availability of suitable habitat in the
vicinity of the bridges.
The infrastructure improvements associated with these bridge replacements could
indirectly affect and improve levels of service, better accommodate merging and
exiting traffic, or reduce travel times, all of which could have land-development
impacts outside the project area. Given that both projects involve the replacement of
existing structures in essentially the same locations, it is not likely that the new
structures would increase accessibility to the adjacent land or result in changes in the
type or volume of traffic using the structures. Although the existing bridges will be
replaced with wider two-lane structures, potentially allowing access to the surrounding
land by larger trucks (including construction equipment), there are other existing
bridges and road access surrounding the existing bridges that allow for the passage of
large vehicles and provide access to the same land area as the subject bridges.
29

Interrelated and Interdependent Actions - An interrelated activity is an activity that is
part of the proposed action and depends on the proposed action for its justification. An
interdependent activity is an activity that has no independent utility apart from the
action under consultation. A determination of whether other activities are interrelated
to, or interdependent with, the proposed action under consultation is made by applying
the "but for" test. That is, it must be determined that the other activity under question
would not occur "but for" the proposed action under consultation. There are no other
projects planned that would satisfy the "but for" test; therefore, there are no interrelated
or interdependent actions that should be considered in this Opinion.
V. CUMULATIVE EFFECTS
Action Area
Cumulative effects include the combined effects of any future state, local, or private actions
that are reasonably certain to occur within the action area covered in this Opinion. Future
federal actions that are unrelated to the proposed action are not considered in this section
because they require .separate consultation pursuant to section 7 of the Act.
We are aware of several potential private actions that may occur and produce significant
cumulative impacts. A proposed 40-unit affordable housing development is proposed on
the north side of US 19E in Burnsville, near Mountain Heritage High School .and .near the
headwaters of the Toe River. In Mitchell County, just north of Spruce Pine, approximately
2,000 to 5,000 acres within the North Toe River drainage area {owned by Penland Bailey
Corporation) is being divided into 0.5- to 2-acre lots, with some of the lots bordering the
North Toe River. A golf course development {planned to be patterned after the Mountain
Air Country Club in Yancey County) is proposed near Altapass in Mitchell County, within
the North Toe River watershed. A 100-acre development is being planned near Huntdale,
in. Yancey and Mitchell Counties, with over 13,000 linear ft of the Cane River and over
2,000 linear ft of the Toe River occurring within the property boundary. Although these
actions are being proposed, it is uncertain if they will be developed or if they will need a
federal permit or money to construct the projects. Therefore, we will. not address these
developments further in this Opinion. We are not aware of any other future state, Local, or
private actions that are reasonably certain to occur within the action area that would not be
subject to section 7 reviews. Therefore, cumulative effects, as defined by the Act, will not
occur and will not be addressed further in this Opinion.
Cumulative Impacts of Incidental Take Anticipated by the Service in Previously Issued
Biological Opinions
In reaching a decision of whether the implementation of activities outlined in the BA are
likely or are not likely. to jeopardize the continued existence of the Appalachian elktoe, we
must factor into our analysis previous biological opinions issued involving the species,
especially those opinions where the Service allowed for incidental take as the area of
30

habitat disturbed, instead of individual mussels. There have been four biological opinions
for the Appalachian elktoe, one within the Nolichucky River drainage and the others
outside the drainage. In May of 2005 we issued a biological opinion to the U.S. Army
Corps of Engineers on the effect of their permit on the Appalachian elktoe for a sewer line
crossing along the Mills River. The amount of incidental take was limited to the
disturbance of habitat 20 ft in width at the construction corridor and 100 ft downstream and
upstream of the construction corridor. The three other biological opinions were rendered to
the NRCS in 2005 for the implementation of the EWP program in the Nolichucky, Pigeon,
and Mills River subbasins. These biological opinions limited the amount of incidental take
to all Appalachian elktoes within at lest 3,325 linear ft of stream within the Nolichucky,
Pigeon, and Mills River subbasins and any additional indirect impacts to Appalachian
elktoes 1,312 ft (400 m) downstream of each of the 40 individual restoration project
"footprints."
VI. CONCLUSION
After reviewing the current status of the Appalachian elktoe; the environmental baseline for
the action area; the effects of bridge construction and demolition; measures identified in the
NCDOT's BA to help minimize the potential impacts of the proposed projects and assist in
the protection, management, and recovery of the species; previously issued Service
nonjeopardy biological opinions that allow various levels of incidental take; any potential
interrelated and interdependent actions associated. with the proposed action; and any
potential cumulative effects, it is the Service's biological opinion that implementing these
projects is not likely to jeopardize the continued existence of the Appalachian elktoe.
Critical habitat will not be adversely modified or destroyed by implementing these projects
as proposed.
INCIDENTAL TAKE STATEMENT
Section 9 of the Act and federal regulations pursuant to section 4(d) of the Act prohibit the
taking of endangered and threatened species, respectively, without. special exemption. Take is
defined as to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to
engage in any such conduct. Harm is further defined by the Service to include significant habitat
modification or degradation that results in death or injury to listed species by significantly
impairing essential behavioral patterns, such as breeding, feeding, or sheltering.. Harass is
defined by the Service as intentional or negligent actions that create the likelihood of injury to
listed species to such an extent as to significantly disrupt normal behavior patterns that include,
but are not limited to, breeding, feeding, or sheltering. Incidental take is defined as take that is
incidental to, and not for the purpose of, the carrying out of an otherwise lawful activity. Under
the terms of section 7(b)(4) and section 7(0}(2), taking that is incidental to and not intended as
part of the agency action is not considered to be prohibited under the Act, provided that such
taking is in compliance with the terms and conditions of this incidental take statement.
31

Amount of Take Anticipated
The Service anticipates that incidental take of the Appalachian elktoe may occur as a result of
construction of the subject bridges. During construction, individual mussels maybe crushed,
harmed by siltation or other water quality degradation, or dislocated because of physical changes
in their habitat.
There will be a combined permanent loss of 89.0 ft2 of stream habitat at the two project sites.
There will also be a combined temporary loss of stream habitat from the construction/demolition
causeways of 26,302 ft2. Downstream impacts (sedimentation), if any, are expected to occur
within 1,312 ft (400 m) of the construction sites. Because there are no reliable data on the
number of Appalachian elktoes buried in the substrate compared to those on the surface (and
even those on the surface are difficult to detect), it is not possible to base the amount of
incidental take on numbers of individual mussels. Rather, the amount of incidental take will be
exceeded if the project "footprint" exceeds 26,391 ft2 or downstream impacts are occurring more
than 1,312 ft (400 m) downstream from the "footprint" of each project. If incidental take is
exceeded, all work should stop, and the Service should be contacted immediately.
EFFECT OF THE TAKE
In this Opinion the Service has determined that this .level of take is not likely to result in jeopardy
to the Appalachian elktoe or destruction or adverse modification of critical habitat.
In addition to the subsequent measures listed in the "Reasonable and Prudent Measures" and
"Terms and Conditions" sections of this Opinion, the measures listed in the "Conservation
Measures" sections of this opinion must be implemented. The Conservation Measures are
project minimization measures, for the construction and demolition of the projects, that were
described by the NCDOT in the BA. The Conservation Measures include, but are not limited to,
the following:
The NCDOT will provide, or contract with biologists who have experience in mussel
relocation techniques, for the removal of Appalachian elktoes from the impact site
and relocate them to the approved relocation site on the North Toe River (between
Penland and Boonford) at about river mile 25.5., according to the procedures in the
approved relocation plan in the BA (see plan. within the BA). The plan details
appropriate collection methods, tagging and recapture, handling and transportation of
individuals, and monitoring protocols, which includes the monitoring of the
relocation sites for recovery, survival (of recovered mussels), movement, and growth
of mussels for a period of 5 years.
sl'he "Conservation Measures" section includes all of the measures Listed within the following subsections:
"Conservation Measures for Bridge Design," "Conservation Measures for Bridge Demolition," "Conservation
Measures for Bridge Construction," and "Additional Conservation Measures."
32

The NCDOT will monitor the river channel and banks at sites upstream, at the
construction sites, and downstream to determine changes in habitat resulting from
activities at these sites (see plan within the BA). If any problems with regard to
stream stability are detected during the monitoring, the NCDOT will attempt to
correct them.
3. As committed to by the NCDOT within the project description of the BA, the
NCDOT will protect and/or restore 100-ft riparian buffers for at least 3,000 linear ft
of stream within the action area. Given that the conservation area has not been
determined or obtained by the NCDOT at the time of the issuance of this Opinion, the
Service will continue to review sites that the NCDOT is considering and approve the
site that is ultimately acquired.
Reasonable and Prudent Measures
The Service believes the following reasonable and prudent measures are necessary and
appropriate to minimize take of the Appalachian elktoe. These nondiscretionary measures
include, but are not limited to, the terms and conditions outlined in this Opinion.
1. The NCDOT will ensure that the contractor understands and follows the measures
listed in the "Conservation Measures," "Reasonable and Prudent Measures," and
"Terms and Conditions" sections of this Opinion.
2. Containment systems will be developed for particular stages of the demolition and
construction of the bridges to minimize impacts to the Appalachian elktoe and its
habitat.
3. Demolition activities and the relocation of mussels will be conducted during time
periods that will result in fewer impacts to the Appalachian elktoe.
4. The NCDOT will send copies of the monitoring reports for the relocated mussels to
the Service's Asheville Field Office every year for the 5-year monitoring time period.
5. During the relocation of mussels, the Service may alter, if needed, methods and plans
for moving the mussels.
6. The NCDOT will notify the Service if their monitoring of the river channel and .river
banks reveals changes in habitat resulting from project activities.
7. All appropriate NCDOT BMP for bridge maintenance, construction, and demolition
will be followed or exceeded for these projects, and any additional BMP listed in the
"Terms and Conditions" section of this Opinion will be followed.
33

Terms and Conditions
In order to be exempt from the prohibitions of section 9 of the Act, the NCDOT must comply
with the following terms and conditions, which implement the reasonable and prudent measures
described previously and outline required reporting and/or monitoring requirements. These
terms and conditions are nondiscretionary and apply to the Toe River.
1. A Service biologist will be present at the preconstruction meeting to cover permit
conditions and discuss any questions the contractor has regarding implementation of
these projects. After the contractor submits plans for various stages of the projects, a
Service biologist will review and provide comments on the plans and will attend any
meetings to discuss implementation of the plans.
2. The NCDOT will ensure that a qualified aquatic biologist is present at critical times
to monitor certain phases of construction, including, but not limited to, initial clearing
for construction, when the causeways are installed, when demolition begins, and
when the causeways are removed. The individual will be present to ensure that the
procedures listed in the "Conservation Measures," "Reasonable and Prudent
Measures," and "Terms and Conditions" sections of this Opinion are being
implemented and that all project plans are being implemented in a manner to ensure
that the conditions of the Opinion are met.
3. If during demolition the bridge decks start to crumble and. enter the river, a
containment system shall be developed and installed to catch debris that inadvertently
falls from the concrete deck of bridge B-2848 and the concrete rail and deck of bridge
B-1443.
4. A containment system shall be developed and installed prior to the removal of the
piers. The conservation measures proposed by the NCDOT recommend placing
turbidity curtains, if the water depth is sufficient, around each of the bents. We are
concerned that turbidity curtains will not be of sufficient strength to capture material
that may enter the river; therefore, we recommend that the design include a
containment system such as the Jersey barriers (with fabric) around each bent.
When constructing the drilled shafts a containment system will be developed so that
material does. not enter the river. Any material by-product will be pumped out of the
shaft and onto uplands and to an off-site disposal. area or will be treated through a
proper stilling basin or silt bag.
6. The conservation measures proposed by the NCDOT state that the saw slurry used
during the demolition process will be contained by approved vacuum methods.
Given that a wet saw will be used, the vacuum methods should include a provision for
pumping and treating the saw slurry outside the project area.
7. The NCDOT will not relocate mussels between May 1 and June 30, the time at which
Appalachian elktoes release glochidia. The NCDOT will relocate the mussels during
34

low flow, low turbidity, and relatively cool weather; the most appropriate time to
accomplish this would be in the fall.
Demolition of the bridge substructure will occur during low flow in order to reduce
the likelihood that sediment will leave the project area and potentially impact
downstream resources.
9. In the BA, the NCDOT proposed to relocate all native mussels, including the
Appalachian elktoe, from the project "footprints," extending downstream 262 ft
(80 m) and upstream 66 ft (20 m) of the two bridge replacements. Representatives of
the Service's Asheville Field Office may determine during relocation of the mussels
that the area the mussels are moved from should be reduced.
10. A Service biologist will review and provide comments on plans proposed to correct
problems that may be revealed in the monitoring of the river channel and banks
within the project area.
11. The erosion-control plan will be in place prior to any ground disturbance. When
needed, combinations oferosion-control measures (such as silt bags in combination
with a stilling basin) will be used to ensure that the most protective measures are
being implemented.
12. Activities in the floodplain will be limited to those needed to construct the proposed
bridges and remove the existing bridges.
13. Work pads will be used when equipment. must be staged in the floodplain to complete
the project construction. The work pads will be constructed by placing fabric matting
down prior to placing the stone work pad. All of the stone and matting will be
removed and disposed of off-site or the stone can be used in areas that require
permanent stone protection after project completion.
14. Access roads and construction staging areas will be minimized to the maximum
extent practicable. The access roads and construction staging areas should be
established from the start of the project and designed with erosion-control measures.
The placement of the access roads and staging areas will be discussed with the
Service and determined at the preconstruction meetings.
15. Riparian vegetation, especially large trees, will be maintained wherever possible. If
riparian areas are disturbed, they will be revegetated with native species as soon as
possible after construction.
16. Upon completion of the project the existing approach fills will be removed to natural
grade, and the area will be planted with native grasses and tree species.
17. Construction will be accomplished in a manner that prevents wet concrete from
coming into contact with water entering or flowing in the river.
35

18. Unconsolidated material (such as sand and dirt) will not be placed directly on the
causeways since the material could be washed off of the causeways or settle into the
causeways and enter the river. If unconsolidated material must be placed on the
causeways, a solid barrier will be placed on the causeways prior to the placement of
the material. The barrier and unconsolidated material will be removed anytime
throughout a work day when the water level rises to a point, or is expected to rise
over night to a point, where material could wash off the causeway or during periods
of inactivity (two or more consecutive days). Any equipment that is placed on the
causeways will also be removed anytime throughout a work day when the water level
rises to a point, or is expected to rise over night to a point, where the equipment could
be flooded or during periods of inactivity (two or more consecutive days). The only
exception to this measure is that the drill rig may be left in place for periods of
inactivity; however, it must also be removed if the water rises or is expected to rise to
a point where the drill rig could be flooded.
19. All construction equipment should be refueled outside the 100-year floodplain or at
least 200 ft from all water bodies (whichever distance is greater) and be protected
with secondary containment. During crucial periods of construction and demolition
when the drill rig and crane cannot be moved, the drill rig and crane can be refueled
while inside the 100-year floodplain provided that spill response materials (such as
spill blankets and fueling diapers) are used during the refueling. Hazardous materials,
fuel, lubricating oils, or other chemicals will be stored outside the 1.00-year floodplain
or at least 200 ft from all water bodies (whichever distance is .greater), preferably at
an upland site. Areas used for borrow or construction by-products will not be located
in wetlands or the 100-year floodplain.
CONSERVATION RECOMMENDATIONS
Section 7(a)(1} of the Act directs federal agencies to use their authorities to further the purposes
of the Act by carrying out conservation programs for the benefit of endangered and threatened
species. The following conservation recommendations are discretionary agency activities to
minimize or avoid adverse effects of a proposed action on listed species or critical habitat, to
help implement recovery plans, or to develop information.
1. Where opportunities exist, work with landowners, the general public, and other
agencies to promote education and information. about the Appalachian elktoe and its
conservation.
2. Pursue additional buffers and conservation opportunities along the main stem ofthe
Cane River, North Toe River, and Toe Rivers and their tributaries, either individually
or in concert with other conservation programs.
3. Explore opportunities to work with local and state water quality officials in order to
minimize or eliminate wastewater and storm-water discharges into the Cane River,
North Toe River, and Toe River.
36

~. Consult ti~~itl~ the Service on projects affecting aquatic habitat in the Toe River
drainage, regardless offiinding source; to ensure compliance with all provisions of
the Act.
In order for the Service to be kept inforn~ed of actions minimizing or avoiding adverse effects or
benefiting listed species or their habitats, we request notification of the implementation of any
conservation recommendations.
REIT1i'TIATI~?NICLOSIi~G STATEMENT
This concludes formal consultation on the actions outlined in your BAs dated Inlay 12, 2005, and
February 21, 2006. As provided in 50 CFR 402.1 b, the reiniiiation of formal consultation is
required where discretionary federal agency involvement or control over the action has been
retained (or is authorized bylaw) and if: { l) the amount or extent of incidental take is exceeded,
(2) new information reveals effects of the agency action that may affect listed species or critical
habitat in a manner or to an extent not considered in this Opinion, (3) the agency action is
subsequently modified in a manner that causes an effect to the listed species or critical habitat
not considered in this Opinion, or (4j a new species is listed or critical habitat is designated that
maybe affected by the action. In instances whexe the amount. or extent of incidental take is
exceeded, any operation catasing such take must cease, pending reinitiation. Consultation should
also be reinitiated if new biological information comes to light that invalidates the assumptions
made regarding the biology or distribution of the Appalachian elktoe within the project area of
the Nolichucky River subbasin in North Carolina.

SR 1304 Over North Toe River
Federal Project BRZ 1304(4)
State Project 8.2880401
TIP No. &2848
Highway Division 13, Hydraulics Unit, Structure Design Unit
In order to avoid and minimize environmental impacts associated with the replacement of Bridge No. 143,
all standard procedures and measures, including NCDOTs Best Management Practices for Protection of
Surface Waters and the Tennessee Valley Authority's (NA) Water Management Standard Conditions will
be strictly enforced during the construction stage of the project. Provisjons to prelude contamination by
toxic substances during the construction interval will also be strictly enforced.
1. In addition to NC DOT Best Management Practices, the contractor must submit a bridge demolition plan
fior.approval by the Division 13 engineer prior to beginning bridge removal. Since some bridge debris will
enter the water, the contractor must submit a work plan sealed by a PE. The contractor's work plan will
detail the,maximum amount of the bridge that can be safely removed dropping minimal portions into the
water. Also, this plan will indicate any proposed use of explosives and the methods to be used to retrieve
and dispose of all components of the existing bridge dropped into the water. The volume of structural
material to be retrieved from the existing bridge will be approximately 150 cubic yards (114.61 cubic
meters).
1. Construction will be accomplished so wet concrete does not contact water entering or flowing in the
river. Demolition of the existing structure will be completed such that minimal asphalt or dirt fill from the
existing deck enters the river. Any debris or cons#ruction material that falls into the river will be
removed immediately.
3. Every effort wilt be made to minimize deck drajnage, the overall footprint of bents, any scour problems,
and any debris accumulation associated with the project.
Roadway Design Unit, Project Development and Environmental Analysis Branch, Roadside
Environmental Unit, Highway Division 13, Structure Design Unit
Upon completion of the project the existing approach fill will be removed to natural grade and the area
will be planted with native grasses and/or tree species such as Hans Fescue/ or Bluegrass or as
recommended by the division engineer.
2. Activities in the flood plain wjll be limited to those needed to construct the proposed bridge and remove
the existing bridge. Areas used for borrow or construction by-products will not be located in
floodplains.

3. Every effort will be made tD minimize work pads in the flood plain. .
4. During and after bridge demolition neither bridge debris, asphalt or dirt fill will be allowed to enter
Waters of the United States. Silt fences, silt bags or other suitable sedimentation control measures may
be used at the approval of the Division Engineer.
Highway Division 13, Hydraulics, PD1~EA, Structure Design Unit
1. NCDOT will coordinate with the U.S. Fish and Wildlife Service to incorporate sufficient measures and
monitoring, as required, in addition to those fisted below, to avoid impacts to the endangered
Appalachian Elktoe mussel (Aiasmidorita raveneliana}.
2. All Elktoe mussel species must be removed prior to construction. Bridge Construction may be subject
to a moratorium. A Consultation in compliance with Section (la) of the Endangered Species Act of
1973 will follow this CE document in order to more closely identify the specific course of action
necessary to minimize impacts to the endangered Appalachian Elktoe Mussel species.
3. The NCDOT Project Development and Environmental Analysis Branch and the U.S. Fish and Wildlife
Service will be invited to the pre-construction conference to discuss with the contractor the provisions
of the Endangered Species Act of 1973 and penalties for violation of the Act.
4. Stringent erosion control measures included in the Division of Water Quality's High Quality Waters
Erosion Control Guidelines will be implemented during all construction activities.
5. Riparian vegetation will be maintained wherever possible, especially large trees.
6. If riparian areas are disturbed, they will be revegetated with native species as soon as possible after
.construction.
7. Prior to construction the contractor will be required to give notification of the construction initiation date
to the U.S. Fish and Wildlife Service, N.C. Wildlife Resources Commission, and the Tennessee Valley
Authority.
8. Pre-let surveys will be performed at-the bridge for occurrence of the Appalachian Elktoe (Alasmidonta
raveneliana}.
9. The North Toe River is classified as a Trout water; North Carolina regulations entitled Design
Standards in Sensitive Watersheds shall be implemented during the design and construction of this
project,. as applicable. A letter of notification, with reference to impacts to mountain trout water habitat,
will be provided th the U.S. Amry Corps of Engineers -Asheville Regulatory Field Office and the N.C.
Wildlife Resources Commission (WRC) office prior to construction of the project.

Bridge No. 143
SR 1304 over North Toe River
Federal-Aid Project No. BRZ-1304 (4)
State Project No. 8.2880401
T.LP. No. 8-2848
Bridge No. i43 in Mitchell and Yancey Counties is listed in the North Carolina Department of
Transportation {NCDOT) 2002-2008 Transportation Improvement Program (T!P) as TIP No. B-2848. The
purpose of this project is to replace Bridge No.143due to its poor condition and substandard design.
This project is being processed as a Federal Categorical Exclusion. Based on the assessment of the
existing human and natural environment, it is concluded that no significant adverse environmental effects
will result from the replacement of Bridge No. 143. Refer to Figures 1 through 4 for location and
illustrations of the project area and existing bridge location.
All measurements contained in this report are in System International metric units, approximate metric
system equivalent units are indicated in parentheses next to the English System equivalents.
SUMMARY OF ENVIRONMENTAL COMMITMENTS
The Environmental Commitments Listed on pages 1 and 2 are intended to minimize impacts to the
Appalachian Elktoe Mussel Species and other species dependent upon the North Toe River.
II. SUMMARY OF RECOMMENDATIONS
The existing one-lane structure (Bridge No. 143} will be replaced with amulti-span two-lane bridge on new
location approximately 50 feet (15.2_meters) downstream of the existing bridge (Alternate S as shown in
Figure 2). The new bridge will be approximately 350 feet (108 meters} in length and will have a clear
roadway width of 24 feet (7.2 meters} consisting of two travel lanes with 2 feet (0.6 meter) shoulders on
each side of the bridge.
The existing bridge will remain in place to maintain traffic during construction. It will be removed after
construction is complete.
The estimated cost of this project, based on current prices, is $1,216,000. This amount includes $66,000
for right-o#-way acquisition and $1,250,000 for construction.
Ill. EXISTING CONDITIONS
Bridge No. 143 is located on SR 1304 approximately 1.4 mi {2.3 kilometers) south of NC 197 in the
community of Huntdale, North Carolina. The bridge crosses over the North Toe River which divides
3

Mitchell and Yancey Counties. Refer to Figure 1 for the existing bridge location and Figures 2 through 4 for
illustrations of the project area.
BRIDGE INFORMATION
Bridge No.143 is a one-lane bridge constructed in 1922. It has five spans, totaling 367 feet (111.9 meters)
in length, and has a clear roadway width of 12 feet {3.6 meters}. The superstructure of the bridge consists
of a reinforced concrete deck, an asphalt wearing surface, and metal guardrails. The substructure consists
of reinforced concrete earth filled spandrel arches, reinforced concrete abutments, and reinforced concrete
piers. Bridge No. 143 was constructed on a vertical curve. The crest of this curve is located approximately
in the middle of the bridge and has estimated 1.0 percent grades on each side of the crest. The bridge
deck in the middle of the bridge is approximately 28 feet {8.5 meters) above the river bottom. The bridge
has no horizontal curvature.
According to the 2002 NCDOT Bridge inspection Report, the bridge has a sufficiency rating of 23.0 and is
considered structurally deficient. The original bridge rails were replaced with metal guardrails in 1980 due
to their deteriorated condition.
There are currently no posted restrictions on the bridge.
NORTH TOE RIVER
Bridge No. 143 is located in a meander of the North Toe River approximately 2,500 feet (762 meters)
upstream from the rivet's confluence with the Cane River. At the existing bridge crossing, the North Toe
River has a drainage area of approximately 44~ square miles (1,145 square kilometers} consisting of
mostly steep, heavily wooded,, mountainous ter: ~. with scattered residential development. The river is
approximately 180 feet (55 meters} wide and has a variable depth of approximately 3 feet (1.0 meters) at
the existing bridge.
Although Mitchell and Yancey Counties are participants in the Federal Emergency Management Agency
(FEMA) National Flood Insurance .Regular Program, the North Toe River within the project area was not
included in the detailed FEMA study. Design flows for this project were estimated using drainage areas
calculated from USGS gauge and rural regression equations from the USGS Water Resources
investigation Report 96-4085.
ROADWAY INFORMATION
SR 1304 begins in Yancey County at the south end of Bridge No. 143, crosses the North Toe River into
MitcheN County and extends eastward ending at NC 197. It is classified as a minor collector in the
Statewide Functional Classification System and primarily serves focal traffic. This two lane highway is
approzimateiy 18.0 feet (5.4 meters) in width and has variable width unpaved shoulders, except over
Bridge No. 143. SR 1304 is a one-lane roadway over the bridge serving two-way traffic controlled by a stop
sign on the south approach of the bridge. The width of SR 1304 measures 3.6 meters (12 ft) over the
bridge.
SR 1304 intersects SR 1417 and SR 1340 at a 65 degree .angle on the south approach of the bridge. It is
tangent across the river but makes a sharp {110 degrees) tum at the north approach. SR 1320 intersects
SR 1304 of the north end of the existing bridge in this sharp curve. Refer to Figure 2 for illustration of these
intersections.
4

Vehicles must enter and exit the one lane bridge at sharp angles. It is likely that large trucks have difficulty
negotiating the toms at each end of the existing bridge.
The posted speed limit on SR 1304 in the vicinity of the bridge is 35 mph.
The 2002 average daily traffic volume on SR 1304 over Bridge No. 143 is estimated to be 200 vehicles per
day (vpd) which includes 2 percent TTST vehicles and 3 percent dual-tired (Dual) vehicles. The 2025
des-gn year average daily affic volume Duct the bridge is expected to be 300 vpd.
GENERAL INFQRMATION ,
This project is located in a rural setting consisting of either scattered residential and commercial
development or is undeveloped mountainous terrain. The small community of liuntdale is located in the
vicinity of the bridge. This community consists of several single family residences, a general store/gas
station, and a church. A CSX Railroad dine runs through the community paralleling the north side of the
North Toe River. Both Mitchell and Yancey Counties have experienced very little growth in the past and
are not expected to substantially increase in population in the future.
According to school officials, no school buses cross Bridge No. 143.
Two accidents were reported within the project area between September 1,1992 and August 31, 2002.
The French Broad Electric Membership Corporation has aerial electrical service lines at both ends of the
existing budge and aerial electrical service crossing the North Toe River just upstream. There are no
utilities attached to Bridge No. 143. Utility impacts for this project are expected to be "lowb.
There are remnants of an old sawmill located at the northeast end of the existing bridge.
There are no U.S. Geological Survey geodetic survey markers located on or near Bridge No. 143.
No major developments or roadway improvements are planned that would impact the historical growth
rates or travel patterns in the area of this project.
IV. ALTERNATIVES
Three replacement alternatives, a "Do-Nothing" altemate, .and a "Rehabilitation" altemate were considered
for this project.
Due to the poor condition of the existing structure, the "Do-Nothing" altemate and the "Rehabilitation°
altemate were eliminated from further study.
Based on the lack of a suitable off-site detour route, no alternatives involving an off-site detour were
considered. Traffic will be maintained on-site using the existing bridge during construction.
5

An °in-place' bridge r~eptacement,_using an on-site detour, will be cost prohibitive due to the cost of a
temporary detour bridge. Based on this; an `in-place" bridge replacement was not considered.
Three alternatives (A, B and C) were studied for replacing Bridge No. 143. Each of these alternatives
consists of a multi-span bridge having a clear roadway width of 24 feet (7.2 meters) which includes two
travel lanes totaling 20 feet (6.0 meters) in width and a 2 feet (0.6 meter) shoulder on each side of the
bridge. The roadway approaches will have a 20 feet (6.0 meter} pavement width and 2 feet (0.6 meter)
unpaved shoulders.
The following is a detailed description of each of the three study altemates (as shown in Figure 2):
ALTERNATE A
This alternative replaces Bridge No. 143 with a new bridge located approximately 500 feet (152.4 meters)
downstream of the existing structure. The proposed river crossing is in a narrow section of the North Toe
River and would provide a shorter bridge than other altemates under study.
Altemate A will require the grade of SR 1320 to be raised approximately 15 feet (4.6 meters} above its
existing elevation from west of the proposed bridge to SR 1304, a distance of approximately 550 feet (16'8
meters). Raising the elevation of SR 1320 will result in longitudinal encroachment upon the North Toe
River and upon the CSX Railroad tracks. Based on review of Mitchell County tax maps, it appears SR
1320 is on CSX Railroad right of way.
Altemate A is not recommended due to the impacts to the North Toe River and to the CSX Railroad.
ALTERNATE B (Recommended)
Altemate B will replace the existing bridge with a new bridge located approximately 50 feet (15.2 meters)
downstream of the existing structure. The existing grade of SR 1320 on the north side of the river will be
raised to match the existing elevation of SR 1304 and the north end of the proposed bridge.
This alternative will be less costly than Altemate C and wil{ have less impact on the natural environment
than Altemate A or C. Altemate B will have a shorter bridge than Altemate C because it will be
downstream of the meander in the North Toe River and west of the horizontal curve in SR 1417/SR 1340.
Altemate B will not encroach upon McKinney Branch located north of SR 1340 and east of the existing
bridge.
ALTERNATE C
This alternative replaces Bridge No. 143 with a new bridge located approximately 50 feet (15.2 meters)
upstream. of the existing structure. Due to the horizontal curvatures of SR 1417/SR 1340 south of the river
and of SR 1320/SR 1304 north of the river, a longer bridge would be required for this altemate.
A small tributary, McKinney Branch, is located on the north side of SR 1340 approximately 90 feet (27
meters) upstream of the existing bridge. McKinney Branch will be relocated by Altemate C. Altemate C will
also impact remnants of an old sawmill located on the north side of the river approximately 130 feet (40
meters) upstream of the existing bridge.
This altemate will require the relocation of aerial electrical service lines extending over the North Toe River
located just upstream of the existing bridge.
6

_,
Aftemate C is not recommended due to the increased cost of a longer bridge and to the impacts to
McKinney Branch.
V. ESTIMATED COSTS
The estimated cost of Attemates A, B and C, based on 2002 dollars, are shown in Table 1.
TABLE 1
ESTIMATED PROJECT COSTS
Alternate A Altemate B

Total $1,341,500 $1,291,900 $1,292,600
The estimated cost of the project, as shown in the 2002-2008 TIP, is $1,452,000,000 (1,250,000 for
construction, $202,000 for right-of--way, with the remainder for planning studies).
Vl.
Bridge No. 143 will be replaced on new location (Altemate B) with amulti-span bridge located
approximately 50 feet (15.2 meters) downstream of the existing structure (see Figure 2). The new bridge
will be approximately 350 feet (108 meters) in length and. will be placed at approximately the same
elevation as the existing structure. The bridge will have a clear roadway width of 24 feet (7.2 meters) which
includes two travel lanes totaling 20 feet (6.0 meters) in width and a 2 feet (0.6 meter) shoulder on each
side of the bridge. The roadway approaches will have a pavement width of 20 feet (6.0 meter) and 2 feet
(0.6 meter) unpaved shoulders on each side.
The length and height of the proposed structure may be increased or decreased as necessary to
accommodate peak flows as determined by further hydraulic studies and to minimize impacts to
endangered species or their habit.
The existing bridge will remain in place to maintain traffic during construction. !t will be removed after
construction is complete.
7

1/II.
A design exception for the design speed will be required for this project due to the horizontal curves on
each end of the new bridge. The construction costs and environmental impacts associated with providing a
design speed of 35 mph, the posted speed limit over the bridge, will be excessive. The design speed of
this project will be less than 30 mph.
VIII. NATURAL RESOURCES
The purpose of studying natural resources is to provide an evaluation of biological resources in the
immediate area of potential project impact. Specifically, the tasks performed for this study include: 1) an
assessment of biological features within the, study corridor including descriptions of vegetation, wildlife,
protected species, wetlands, and water quality; 2) an evaluation of probable impacts resulting from
construction; and 3} a preliminary determination of permit needs.
Methods
Materials and research data in support of this investigation were derived from a number of sources
including applicable U.S. Geological Survey (USGS) 7.5 minute .quadrangle topographic mapping
(Huntdale, NC), U.S. Fish and Wildlife Service (FWS) National Wetlands inventory mapping, Natural
Resources Conservation Service draft soils mapping (USDA Unpublished), and recent aerial photography
(scale 1:1200).
The si#e was initially visited on February 6, 1997 and several follow- up visits were made to survey for
protected species. The study corridor was walked .and visually surveyed for significant fieatures. The study
corridor is approximately 305 by 1000 by 600 feet (183 meters). Impact calculations for each alternate are
based on right-of--way width, which is approximately 80 feet. (24 meters) for each alternate; actual impacts
will be limited to construction limits and will be less than those shown for right-of-way. Special concerns
evaluated in the field include potential habitat for protected species, wetlands, and water quality protection
in the North Toe River.
Plant community descriptions are based on a classification system utilized by North Carolina Natural
Heritage Program (NHP} (Schafale and Weakiey 1990). When appropriate, community classifications were
modified to heifer reflect field observations.. Vascular plant names follow nomenclature found in Radford et
al. (1968). Jurisdictional areas were identified using the three parameter approach (hydrophytic vegetation,
hydric soils, wetland hydrology) following U.S. Army Corps of Engineers (COE) delineation guidelines (DOA
1987). Jurisdictional areas were characterized according to a classification scheme established by
Cowardin of al. (1979}. Habitat used by terrestrial wildlife and aquatic organisms, as well as expected
population distributions, were determined through field observations, evaluation of availab{e habitat, and
supportive documentation (Martof et a1.1980, Webster et aL 1985, Menhinick 1991, Hamel 1992, Rohde of
al. 1994). Water quality information for area streams and tributaries was derived from the North Carolina
Departmen# of Environment, Health and Natural Resources (DEHNRj, Division of Water Quality {DEM
1989, DEM 1993, DEM 1994). Quantitative sampling was not undertaken to support existing data.
The most current FWS listing of federal protected species with ranges which extend into Mitchell and
Yancey Counties was obtained prior to initiation of the field investigation. In addition, NHP records
8

documenting presence of .federal . or state listed species were consulted before oommenang the field
investigation.
Phvsio4raphy and Soils
The study corridor is located in the Mountain physiographic province. Topography is characterized by
strongly sloping to very steep uplands with narrow floodplains along drainages. Elevations in the study
corridor range from approximately 2040 feet (620 meters) above sea level along the river to approximately
2060 feet (ii35 meters) along the slope southwest of the bridge (USGS Huntdale, NC quadrangle).
Soils in the study corridor are dominated by the Biltmore sand (0 to 3 percent slope) mapping unit along the
inside bend of the river, Unison loam (15 to 30 percent slopes) mapping unit along the outside bend of the
river, and the Buladean-Chestnut complex (50 to 95 percent slopes} mapping unit along the slope
southwest of the bridge. The Biltmore sand series (Typic Udipsammer>fs) is a well drained to moderately
well drained, non-hydric series located on floodplains and is subject to periodic flooding. The Unison loam
series is a well drained, non-hydric series found on high stream terraces, benches, coves, and coUuvial
fans. The Buladean soils and Chestnut soils (Typic Dysfrochrepfs) are well drained, non-fiydric soils found
on side slopes.
WATER RESOURCES
Waters impacted
The study condor is located within sub-basin 040306 of the French Broad River Basin (DEM 1994). This
area is part of USGS accounting unit 060101 of the Tennessee River Region. Bridge No.143 crosses the
North Toe River approxima#ely 2500 feet (762 meters) upstream from its confluence with the Cane River;
the Nolichucky River is formed at this confluence. A small tributary, McKinney Branch, is also present
within the study corridor. McKinney Branch enters the North Toe River approximately 90 feet (27 meters)
upstream from the bridge. The North Toe River section from the town of Spruce Pine water supply intake
downstream to the Nolichucky River has been assigned Stream Index Number 7-2-(27.7) by the North
Carolina Department of Environment, Health and Natural Resources (DEHNR), Division of Water Quality
{DWQ McKinney Branch has been assigned Stream index Number 7-2-71.
Stream Characteristics
The North Toe River is a large mountain river with swift flow over sandy and rocky substrate. Gravel bars
are present within the channel downstream from the bridge, and large rock outcrops are present upstream
and downstream from the bridge. A series of submerged rock ledges is present beginning approximately
160 feet (49 meters) downstream from the bridge. The North Toe River is approximately 180 feet (55
meters) wide at the existing bridge, but widens to approximately 200 feet (61 meters) immediately
upstream and downstream within the study corridor. River depth is dependent on hydrologic conditions,
and appears to be about 3 feet {0.9 meters) at the bridge. Little or no rooted aquatic vegetation is
apparent in the river channel, but some organic debris (i.e., branches, leaves) was apparent. Extensive
woody debris has been placed or has accumulated on the left bank upstream from the bridge, which has in
tum .served to trap a large amount of sand and sediment.
McKinney Branch., a perennial stream which roughly parallels SR 1340, flows under a small bridge on
SR 1340 and through a culvert under a driveway leading to private residences to empty into the North Toe
River approximately 90 feet (27 meters) upstream from the existing bridge. McKinney Branch varies din
9

width from 5 feet (1.5 meters) upstream from the culvert, to 3 feet (0.9 meters) downstream from the
culvert. Stream flaw on the date of the site visit was swift with 0.2 to 0.5 feet (0.1 to 0.2 meters) of water
flowing overmostiy sandy substrate upstream from the culvert, and sandy and rocky substrate downstream
from the culvert. The banks within the lower reach within the study corridor have been substantially
impacted by residential development and roadway maintenance.
A small, intermittent drain approximately 1 to 3 feet (0.3 to 0.9 meters) wide flows from a culvert under SR
1304 into the North.Toe River approximately 380 feet (116 meters) upstream from Bridge No. 143. Water
depth is approximately 0.3 feet (0.1 meters) with swift flow over sandy, mostly vegetated substrate.
Best Usage Classifications and Water Quality
Classifications are assigned to waters of the State of North Carolina based on the existing or contemplated
best usage of various streams or segments of streams in the basin. A best usage classification of C Tr has
been assigned to the North Toe River from the town of Spruce Pine water supply intake downstream to the
Nolichucky River, and to McKinney Branch from its source to the North Toe River (DEM 1993). The
designation C denotes that appropriate uses include aquatic life propagation and survival, fishing, wildlife,
secondary recreation, and agriculture. Secondary recreation refers to human body contact with waters on
an infrequent or inradental basis. The Tr designation is used for trout waters characterized as waters
suitable for natural trout propagation and maintenance of stocked trout.
No High Quality Waters (HQW), Outstanding Resource Waters (ORW), WS f, or WS II Waters occur within
1 mi (1.6 kilometers) of the study corridor. Neither the North Toe River nor McKinney Branch is designated
as a North Carolina Natural and Scenic River, nor as a national Wild and Scenic River.
There are several permitted point source dischargers upstream from the study corridor (DEM 1989, DEM
1994). The nearest facility is more than 10 mi upstream. These facilities, along with flows (in MGD), are
presented in the following table:

Unimin Corp-Quartz N00000175/001North Toe River Mitchell 3.6100
No significant non-point discharges were noted in the study corridor.
Despite the number of permitted discharges upstream, the water quality of the North Toe River in the
vicinity of the study corridor has been rated as Good to Good-Fair based on ratings assigned by the
Benthic Macroinvertebrate Ambient Network (BMAN). BMAN addresses long-term trends in water quality
at fixed monitoring sites by sampling for selected benthic macroinvertebrates and then evaluating species
richness and overall biomass to assess overall water quality (DEM '1989). In addition to BMAN sampling
stations, DWQ has additional benthic macroinvertebrate sampling stations in the North Toe River upstream
and downstream from the study condor. in 1992, sampling stations in the North Toe River upstream from
10

the study corridor received Good or Good-Fair bioclassfications, and a station downstream from the study
corridor received a Good biociassification (DEM 1994}.
Another measure of water quality being used is the North Carolina Index of Biotic Integrity (NCIBI), which
assesses biological integrity using the structure and health of the fish community. There is a NCIBI station
on the North Toe River along NC 197, which is approximately 1.3 to 2.fi miles (2.1 to 4.2 kilometers)
upstream from the study corridor. This site received a rating of Good in 1992 (DEM 1994).
Anticipated Impacts to Water Resources
Stringent erosion control measures included in the Division of Water Quality's High Quality Waters Erosion
Control Guidelines will be implemented during a!I construction activities. In order to avoid and minimize
environmental impacts associated with the replacement of Bridge No. 143, all standard procedures and
measures, including NCDOT's Best Management Practices for Protection of Surface Waters and the
Tennessee Valley Authority's (TVA} Water Management Standard Conditions will be strictly enforced
during the construction stage of the project.
Because a federally endangered freshwater mussel, the Appalachian elktoe (Alasmidonfa raveneliana), has
been found in the vicinity of the existing bridge, the above design and construction standards should be
stringently followed during the life of this project to minimize impacts to this species.
No adverse long-term impacts to water resources are expected to result from proposed improvements.
The proposed bridge replacement will allow for continuation of present stream flow in the North Toe River,
thereby protecting stream integrity. Alternatives A and B will avoid impacts to McKinney Branch; however,
a small section of McKinney Branch is located within the right-of-way for Alternative C. The small, unnamed
intermittent tributary to the North Toe River has been avoided by all project alternatives and will not be
impacted.
BIOTIC RESOURCES
Plant Communities
Three distinct plant communities were identified within the study corridor: hardwood forest, riverine bar, and
maintained/disturbed areas. These plant communities are described below..
Hardwood Forest -Hardwood forest is located on the steep slope near the western end of the bridge and
in a narrow band between SR 1417 and the river. Within the study corridor, this community is represented
by ecotonal edge; no forest interior is affected. In addition to the hardwoods; then: are a few needie-
bearing canopy trees. Canopy species include white pine (Pines strobes), eastern hemlock (Tsuga
canadense), black birch (Befula lenfa), northern red oak (Quercus rubs), black locust (Robinia
pseudoacacia), tuiip tree (Liriodendron fuliprfera), and American sycamore (P/afanus occidentalis).
Subcanopy trees are sparse and include black cherry (Prunes serofina), maple (Ater sp.), American beech
(Pages grand>folia), and canopy species. Shrubs include rosebay (Rhododendron maximum}, witch hazel
(Hamamelis virginiana}, and ironwood (Carpinus caroliniana), Christmas fern {Polysfichum acrostichoides)
and rosettes of various perennials were growing among the hillside rocks.
11

lRiverine Bar -This community is represented by two small riverine bars located approximately 91 to 152
meters (300 to 500 ft) downstream from the existing bridge. F~ctensive sand deposits may periodically
cover much of the rocky substrate. Vegetative cover is sparse and dominated by shrubs. Species present
along the river such as ash-leaved maple (Acer negundo) and silky dogwood (Comas amomum) may
become established as shrubs but are not expected to mature into trees due to frequent overwash and
scouring.
MaintainedlDisturbed Areas -This community includes the roadsides, mowed lawns, garden plots, and
disturbed river bank areas. Scattered trees remain in this community and include black locust, American
sycamore, ash-leaved maple, red maple (A. rubrum), and black walnut (Jugtans nigra). Herbaceous
species include evening primrose (Oenothera biennis), goldenrods {Solidago spp.), asters (Aster spp.),
wingstem (Verbesina altemifolia), giant ragweed .(Ambrosia fri~rda), Japanese knotweed (Potygonum
cuspidatum), jimson weed {Datum ~ stramonium), iovevine (Cascara sp.), panic grass {Panicum sp.),
Johnson grass (Sorghum halapense),wild-rye (Elymus virginicus), and foxtail grass (Setaria sp.).
Anticipated Impacts to Plant Communities
Anticipated impacts to plant communities are estimated based on the amount of each plant community
present within the projected right-of-way; actual impacts within construction limits will be less. A summary
of potential plant community impacts is presented in Table 2.

Permanent impacts to plant communities as a result of bridge replacement. are generally restricted to
narrow strips adjacent to the existing bridge and roadway approach segments.. The total potential impact to
plant communities based on right-of-way is similar among the three alternatives, with ranges between 1.58
ac (C LL hectares) for Alternative B to 1.75 ac (0..71 hectares) for Alternative A. However, most of this
paten:::<. impact for each alternative is within maintainedldisturbed areas and does not infringe upon
12

M ~
adjacent natural communities. Alternative A has a higher relative impact~to natural communities (32 percent
of tots! potential impact) than either Alternative B or C (16 and 15 percent of total potential impact,
respectively).
Wildlife
Tem;strial
Most of the study condor consists of maintained/disturbed areas. Birds observed within or adjacent to the
corridor include northern cardinal (Cardinalis cardinalis), song sparrow (Melospiza melodia), blue jay
(Cyanocitta cristata), American crow (Corvus brachyrhynchos), Carolina wren (Thryofhorus ludovicianus),
eastem bluebird (Sialis sialia), pileated woodpecker (Dryocopus pileatus), white-breasted nuthatch (Sitta
carolinensis), and Carolina chickadee (Pares carolinensis). Other birds, such as red-tailed hawk (Buteo
jamaicensis), mourning dove (Zenaida macroura), eastem screech owl (Ofus asio), tufted titmouse (Pares
bicolor), American robin (Turdus migratorius}, northern oriole (Icterus galbu-a) and indigo bunting
(Passerina cyanea) may be expected to occur within the ecotonal woodland and maintained/disturbed
communities within the study condor.
Mammal sign (tracks) observed within the study condor included cottontail (Sylvilagus sp.), domestic dog
(Canis familiaris), and house cat (Fells catus). Other species expected include gray squirrel (Sciurus
carolinensis), opportunistic species such as Virginia opossum (Didelphis virginianus) and raccoon (Procyon
lotor~, and various rodents. Due to the season in which the field work was conducted, no terrestrial reptile
or amphibian species were documented within the study corridor.
Aquatic-
Limited dip-netting within the study corridor did not yield any fish; however, the varied riverine habitat and
good water quality is expected to support numerous species of minnows, darters, and other fish. Species
that may be present include central stoneroller (Campostoma anomalum), whitetail shiner (Cyprinella
galacturus), teiecope and mirror shiners (Notropis telescopes and N. spectrunculus), fatiips minnow
(Phenacobius crassilabrum), white sucker 'Catostomus comrnerson~), black redhorse (Moxostoma
duquesne~), greenside darter (Etheostoma blE:.~ codes), sharphead darter (E. acuticeps), banded darter (F.
zonate), gilt darter (Percina evides), and mottieo sculpin (Cotfus bairdi). Potential game fish which may be
present within the study corridor include rock bass (Amblop!>fes rupesfris}, redbreast sunfish (Lepomis
audtus), smalimouth bass (Micropterus dolomieu), and channel catfish (Icfalurus punctatus) (Menhinick
1991, Rohde et a1.1994). There are no~anadromous fish within this system.
Aquatic rnacroinvertebrates observed in the stream included the Asiatic clam (Corbicula fluminea). Stream
bank surveys did not yield any shell fragments which could indicate freshwater mussel presence within the
study corridor; however, NHP files indicate that Appalachian elktoe (Alasmidonta raveneliana} and wavy-
rayed tampmussel (Lampsilis fasciola) have been found within or adjacent to the study corridor. Field
evacuations indicate that habitat for these species is present within the study corridor.
Limited surveys did not result in documenting any salamanders in the stream. The stream provides
suitable habitat for a few aquatic and semi-aquatic reptiles and amphibians such as shovelnose
salamander (Leurognathus marmoratus}, blackbelly salamander (Desmognathus quadromaculafus), and
queen snake (Regina septemvrhata).

Anticiaated Irnaacts to Wildlffe
Due to the limited extent of infringement on natural communities, the proposed bridge replacement will not
result in significant loss or displacement of known terrestrial animal populations. Potential down-stream
impacts to aquatic habitat will be avoided by bridging the system to maintain regular flow and stream
integrity. In addition, temporary impacts. to downstream habitat from increased sediment during construction
wil! be minim¢ed by implementing the NCDOT's Best Management Practices for Surface Waters and North
Carolina regulations entitled Design Standards in Sensitive Watersheds, as practicable, during
construction. These measures should be stringently followed to reduce impacts to the Appalachian elktoe,
a federally-endangered species.
SPECIAL TOPICS
Waters of the United States
Surface waters within the embankments of the North Toe River and McKinney Branch are subject to
jurisdictional consideration under Section 404 of the Clean Water Act as "waters of the United States" (33
CFR 328.3). The waters of the North Toe River and McKinney Branch exhibit characteristics of riverine,
upper perennial, unconsolidated bottom, permanently flooded waters (R3UBH}.
Alternatives B and C will bridge the open waters of the North Toe River, negating the need for din:ct
encroachment into riverine waters. Altemative A may impact 00.17 ac. (07 hectares} of open water area of
the North Toe River due to encroachments associated with raising the roadbed northwest of the bridge.
This encroachment into riverine waters may extend up to 30 feet (9 meters) .from shore along
approximately 600 feet (183 meters} of river bank. This encroachment for Altemative A will be required for
necessary approach improvements to SR 1320; the remaining open waters of the North Toe River would
be bridged. The ~ open waters of the North Toe River within the right-of-way for each alternative are
presented in Table 3. The open waters for Altemative C include the open waters of McKinney Branch
(less than 0.01 ac (0.004 hectares)) within the Altemative Crght-of-way.

Wetlands subject to review under Section 404 of the Clean Water Act (33 U.S.C. 1344) are defined by the
presence of three primary criteria: hydric soils, hydrophytic vegetation, and evidence of hydrology at or near
the .surface for a portion (12.5 percent) of the growing season (DOA 1987). Based on the three parameter
14

` }
approach, limited jurisdictional wetlands occur within the study corridor within the linear, intermittent drain
located upstream from the bridge. This drain exhibits characteristics of palustrine, emergent wetlands
(PEM), with evidence of hydric soil characteristics (i.e., gleying), intermittent surface flooding and saturation
at the surface, and dominance by hydrophytic herbaceous vegetation. This drain covers an area
approximately 110 by 3 feet (34 by 1 meters); however, none of the alternatives will impact this
jurisdictiona! area.
Permits
This project is being processed as a Categorical Exclusion (CE) under Federal Highway Administration
(FHWA} guidelines. Nationwide Permit (NWP) #23 (33 CFR 330.5(a)(23}] has been issued by the COE for
CEs due to expected minimal impact. DWQ has issued a Genera! 401 Water Quality Certification for NWP
#23. However, use of this permit will nsquire written notice to DWQ. in the event that NWP #23 will not
.suffice, minor impacts attributed to bridging and associated approach improvements are expected to qualify
under General Bridge Permit 031 issued by the Wilmington COE District. Notification to the Wilmington
COE office is required if this general permit is utilized.
Mitchell and Yancey Counties are among the twenty-five mountain counties designated as having trout
waters. The COE has implemented discretionary authority to override certain nationwide and general
permits which authorize the discharge of dredged or fill materials into North Carolina designated trout
waters. Generally, projects involving trout stream infringement, including all waters upstream to and above
their headwaters, can be processed under either General Bridge Permit 031 or individual Permit. Projects
in trout waters require review by the DEHNR, Wildlife Resources Commission (WRC). Neither the North
Toe River section within and downstream from the study corridor, nor the receiving waters of the
Nolichucky River are designated by the WRC as Public Mountain Trout Waters.
Review of this project by the Tennessee Valley Authority (TVA) is required under Section 26a of the TVA
Act. The TVA will require the use of Best Management and Best Engineering Practices as outlined in its
Wafer Management Standard Conditions.
Foundation test borings, if required, will be approved under General 401 Certification Number.
3027/Nationwide Permit No. 6 for Survey Activities. Written concurrence from the N.C. Wildlife Resources
Commission and the COE will be required.
Mitigation
Compensatory mitigation is not proposed for this project due to the limited nature of project .impacts.
However, utilization of the NCDOT's Best Management Practices for Surface Wafers, as practicable, during
construction is recommended in an effort to minimize impacts.

Bog Turtle -The bog turtle is a small turtle reaching an adult size of approximately 3 to 4 inches (8 to 10
centimeters). This otherwise darkly-colored species is readily identifiable by the presence of a bright
orange or yellow blotch on the sides of the head and neck (Martof ef. a1.1980). The bog turtle has declined
drastically within the northern portion of its range due to over-collection and habitat alteration. As a result,
the FWS officially proposed in the January 29, 1997 Federal Register (fit FR 4229) to list bog turtle as
threatened within the northern portion of its range, and within the southern portion of its range, which
includes North Carolina, the bog turtle is proposed for fisting as threatened due to similarity of appearance
to the northern population. The proposed listing would allow incidental take of bog turtles in the southern
population resulting from otherwise Lawful activity.
The bog turtle is typically found in bogs, marshes, and wet pastures, usually in association with aquatic or
semi-aquatic vegetation and small, shallow streams over soft bottoms (Palmer and Braswell 1995). In
North Carolina, bog turtles have a discontinuous distribution in the Mountains and western Piedmont. NHP
records do .not indicate the bog turtle has been documented within 2.0 mi (3.2 kilometers} of the project
bridge.
BIOLOGICAL CONCLUSION: The bog turtle is listed- as Proposed Threatened due to Similarity of
Appearance (T S/A). T SIA species are not subject to Section (7a) consultation and a biological
conclusion is not required. However, this project is not expected to affect the bog turtle since the
only palustrine emergent wetlands in the study corridor will not be impacted by any of the
alternatives.
16

Virginia Big-eared Bat -The Virginia big-eared bat, formerly assigned to the genus Plecotus, is an
endangered, isolated eastem subspecies of a more common, widespread species of bat. Vrginia big-
eared bat is distinguished from all other eastem bats except Rafinesque's big-eared bat (C. rafinesquir) by
its large ears, which equal nearly half the body length. Vrginia big-eared bat differs from Rafinesque's big-
eared bat in having huffy or brownish, rather than whitish underparts {Handley 1991), hairs with little
contrast between bases and tips, and having hair on the feet that does not extend beyond the tips of the
toes (Webster et ai.1985).
In North Carolina, Virginia big-eared bats roost year-round in limestone caves at elevations above 1500
feet (460 meters) (Webster et al. 1985). Mines are rarely used for roosting (LeGrand and Hall 1995).
Virginia big-eared bats typically forage within 2.mi Q3.2 kilometers from the roast (Handley 1991). NHP
records do not indicate that Virginia big-eared bat has been documented within 2.0 mi (3.2 kilometers) of
the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to affect Virginia big-eared bat due to
the absence of known roosting caves within the study corridor. NO EFFECT
Peregrine falcon -The peregrine falcon is a medium-sized falcon, reaching a ~~ngth between 16 to 20 in
(41 and 51 centimeters), or slightly larger than an American crow (Corvus brac.~yrhynchos). Adults have
bluish-gray backs and wings, barring on the pale underparts, and a black nape and crown with a wide black
wedge extending below the eye. Immature peregrine fa{cons are dark brown above with a heavily streaked
breast, and a dark bar or wedge is present below the eye (NGS 1987). Peregrine falcons feed on medium-
sized birds, including waterfowl, shorebirds, and pigeons, which they strike in midair. Peregrine falcons
migrate in the fall, but over wintering birds may be present along the North Carolina coast (Hamel 1992).
Peregrine falcons were extirpated from nesting sites in .the mountains of North Carolina, but have been
reintroduced to westem North Carolina through a hacking program (captive-reared and released).
Peregrine falcons nest on ledges on remote cliffs in areas where a mixture of forests and extensive fields,
marshes, or water is present (Hamel 1992). NHP records do not indicate that .peregrine falcon has been
documented within 2.0 mi (3.2 kilometers) of the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to affect peregrine falcons due to the
absence of suitable nesting habitat (remote cliffs} within the study corridor. Since NHP records do
not indicate that peregrine falcons have been recorded as nesting in the project vicinity, there are
no impacts anticipated to nesting or foraging habitats. NO EFFECT
Eastern Cougar -The-eastem cougar is a possibly extinct eastem subspecies of the widespread mountain
lion species. This species was possibly extirpated from North Carolina by the late 1800s although recent
sporadic sightings have been reported. from remote areas ~of the mountains and coastal plain (Lee 1987).
Mountain lions are large, long-tailed cats; adult males-may measure 7 to 9 feet (2.1 to 2.7 meters) total
length with females averaging 30 to 40 percent smaller (Handley 1991). Adult mountain lion tracks
measure approximately 3.5 inches (9 centimeters} (Lee 1987}.
Recent specimens of mountain lion taken in North Carolina and elsewhere in mid-Atlantic states have
proved to be individuals of other subspecies that have escaped or been released from captivity (Lee 1987,
Handley 1991). The eastem cougar would require large tracts of relatively undisturbed habitat that support
17

large populations ~of white-tailed deer (Webster of at. 1985). NHP records do not indicate that eastern
cougar has been documented within 2.0 mi (3.2 kilometers) of the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to affect eastern cougar due to the
absence of suitably remote wildemess'within the study condor. NO EFFECT
Carolina Northern Flying Squirrel -The .Carolina northern flying squirrel is an isolated, endangered
subspecies of the more wide-ranging northern flying squirrel. Flying squirrels are nocturnal and have a
loose, fully furred fold of skin on each side of the body between the wrists and the ankles that enable the
squirrels to glide from trees to other trees or to the ground for foraging. Carofina northern flying squirrel can
be distinguished from the similar southern flying squirrel (G. volans) by larger size (ranging from 26.4 to
10.2 to 12.0 inches {30.5 centimeters) total length) and byhaving gray rather than white bases of the
ventral hairs (Weigl 1987).
The Carolina northern flying squirrel typically occurs in spruce-fir forests and mature hardwood forest
adjacent to spruce-fir forests at elevations above 4000 feet (1200 meters) (Weigl 1987). Endemic to the
Appalachians of western North Carolina and eastern Tennessee, this subspecies is known from the Great
Smoky Mountains, Roan Mountain, and Mount Mitchell. NHP records do not indicate that Carofina northern
flying squirrel has been documented within 2.0 mi (3.2 kilometers) of the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to affect Carofina northern flying
squirrel due to the absence of suitable habitat within the low elevation (approximately 2040 feet
0620 meters}} study ~rridor. NO EFFECT
Indiana Bat -The Indiana bat is a small, brown bat measuring 3.0 to 3.6 inches (7.7 to 9.1 centimeters)
total length. The Indiana bat is distinguished from other eastern bats by having a keeled caicar
(cartilaginous projection from the hind foot), relatively small ears that do not extend beyond the nose when
pulled forward, short toe hairs that do not extend beyond the toes, and two tiny teeth in a gap between the
canines and cheek teeth (Handley 1991).
Indiana bats hibernate in winter in limestone caves usually where standing water is present (Webster et ai.
1985). Indiana bats also use mine tunnels for hibernation (Handley 1991). In summer, males continue to
roost in caves, but females roost in maternity colonies located in hollow trees and under loose bark of trees
typically located near streams or small rivers (Webster et a!. 1985}. Indiana bats forage over tn~e-fined
streams and upland woods (Handley 1991).. NHP records do not indicate that Indiana bat has been
documented within 2.0 mi {3.2 kilameters) of the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to .affect Indiana bats due to the
absence of known roosting caves within the study corridor. NO EFFECT

Appalachian Elktoe -Appalachian eiktoe is a~small, subovate to kidney-shaped freshwater mussel that
grows to approximately 3.1 inches (8.0 centimeters) length, l .4 inches (3.5 centimeters) height, and 1.0
inches (2.5 centimeters) width (Clarke 1981). The shell is thin, but not fragile, and exhibits slight inflation
along .the posterior ridge near the center of the shell. Beaks project only slightly above the hinge line.
Lateral teeth are absent; however, the hinge ..plate of both valves is thickened. Small, pyramidal,
compressed pseudocardinal teeth are present, and an inteniental projection is present in the left valve.
Juveniles are yellowish brown, but the periostracum (outer shell surface) is thicker and dark brown in
adults. individuals may be variably marked with prominent to obscure greenish rays. The nacre (shell
interior) is shiny, blue to bluish white with salmon, pinkish, or brownish coloring in the central portion of the
shell and beak cavity.
Appalachian elktoe is endemic to the upper Tennessee River system in the mountains of western North
Carolina and eastern Tennessee. Appalachian elktoe habitat has been described as riffle areas with gravel
and cobble substrate (TSCFTM 1990). in North Carolina, this species may now be restricted to the Little
Tennessee and Nolichucky drainages (LeGrand and Hall 1995). Recent WRC surveys have documented
this species in the Little Tennessee River in Macon and Swain Counties, Cane River in Yancey County,
and Nolichucky and North Toe Rivers in Yancey and Mitchell Counties. NHP reconis indicate that
Appalachian elktoe has been documented within the North Toe River within or adjacent to the study
corridor.
BIOLOGICAL CONCLUSION: Because habitat for Appalachian elktoe exists within the study
corridor, and the species has been documented recently within or adjacent~to the study corridor,
,detailed surveys will be necessary to .determine whether individuals are present within the impact
area. Informal consultation should be initiated with the U.S. Fish and Wildlife Service (FWS)
regarding measures to be taken to avoid adverse effects to Appalachian elktoe. Impacts to this
species will be minimized by implementing the NCDOT's Best Management Practices for Surface
Waters and North Carolina regulations entitled Design Standards in Sensitive Watersheds, =s
practicable, during construction. UNRESOLVED
A Consultation in compliance with Section (7a) of the Endangered Species Act of 1973 will follow this CE
document in order to more closely identify the specific course of action necessary to minimize impacts to
the endangered Appalachian Elktoe Mussel species.
Spreading Avers -Spreading avers is an erect, densely hairy, perennial herb to 50 centimeters (20
inches )tall. A basal rosette of odd-pinnately compound leaves is produced from a horizontal rhizome.
These leaves are .long stalked and terminated by a large kidney-shaped lobe; tiny. leafle#s are usuaNy
present below the terminal .lobe (K-al 1983). Small, sessile, serrated leaves are found on the flowering
stem. Lanceolate sepals and relatively long petal lengths of 1.3 to 2.0 centimeters (0.5 to 0.8 inches) help
differentiate spreading avers from related species (Massey et a1.1983). Bright yellow, five-petaled flowers
approximately 2.4 to 3.1 inches (6 to 8 centimeters) across are produced from June to August; these are
followed between July and October by hairy achenes with a persistent, straight style approximately 0.2
inches (1 centimeters) long (Massey et al 1983}. Vegetative parts may emerge in May and persist
through October.
Spreading avers usually occurs at elevations greater than 5000 feet (1524 meters) in mountain grass
balds or in grassy clearings, in heath balds as well as in crevices of granitic rock; it cannot tolerate shading
19

or crowding (Kral 1983). Spreading avens is found in a few northwestern counties of North Carolina, and in
nearby counties of Tennessee. NHP records do not indicate that spreading avens has been documented
within 2.0 mi (3.2 kilometers} of the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to affect spreading avens due to the
absence of suitable habitat within the low elevation (approximately 620 meters (2040 ft)) study
corridor. NO EFFECT
Roan Mountain Biuet -Roan Mountain bluet, formerly treated as a variety of the summer bluet (Houstonia
(=Hedyotisj purpurea), is a low, erect to spreading perennial herb with a squarish stem typically growing to
6 inches (15 centimeters) high. The leaves are opposite, sessile, rounded basally but taper to a pointed
tip and have smooth, toothless margins. Small, deep purple, tubular flowers are produced on small
terminal clusters in June and July with fruiting occurring in July and August. It differs from the more
common H. purpurea by having larger, smooth-edged leaves, and by larger flowers, capsules, and seeds
(Weakley 1993).
Roan Mountain bluet is endemic to the high Blue Ridge mountains of North Carolina and Tennessee,
mostly from 4200 to 6300 feet (1280 to 1920 meters) in elevation. It grows in crevices of rock outcrops as
well as in thin, gravelly soils of grassy balds near summit outcrops (Weakley 1993). NHP records do not
indicate that Roan Mountain bluet has been documented within 2.0 mi (3.2 kilometers) of the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to affect Roan Mountain bluet due to
the absence of suitable habitat within the low elevation (approximately 2040 feet (620 meters))
study corridor. NO EFFECT
Heller's Blazing Star - Heller's blazing star is an erect herbaceous perennial with glabrous stems that
reaches heights of 10 to 4 to 20 inches (50 centimeters}. The leaves .are simple, linear to lanceolate,
alternate, and arranged spirally along the stem. Leaf size is variable, with a gradual decrease in-size up
the stem. The inflorescence consists of compact heads arranged in a raceme-like fashion along the stem.
The heads typically contain seven to ten tubular florets which may be purple to lavender in color. Hellers
blazing star is distinguish~~ from related species by shorter height and relatively short pappus (modified
calyx lobes) half or less the length of the corolla tube: Flowers are produced from July to September, with
fruiting occurring from August to October (Massey of a~.1983).
HeBer's blazing star has been found on rocky summits at high elevations in the mountains of western North
Carolina. This species typically is found in full sun growing in shallow, acidic soils on or around granitic
outcrops, ledges, and cliff faces (Kral 1983, Massey of al. 1983). Heller's blazing star is reported to occur
at elevations between approximately 1070 and 1900 meters. NHP records do not indicate that Heller's
blazing star has been documented within 2 kilometers. (32.0 mi) of the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to affect Heller's blazing star due to the
absence of suitable habitat within the low elevation (approximately 62040 feet (20 meters}) study
condor. NO EFFECT
Blue Ridge Galdenrad -Blue Ridge goldenrod is an erect, perennial herb growing to 16 inches (40
centimeters) in height with simple leaves in a basal rosette and along the stem. Leaves are serrate, ciliate,
smooth to slightly scabrous above and glabrous beneath, and progressively reduced in size and more
20

x
sessile towards the inflorescence. The unpleasant aroma of this plant leads to an ai#emative common
name, skunk goldenrod. Blue Ridge goldenrod can be distinguished from other two goldenrod species
having a corymt:~~nn inflorescence and golden rays by its shorter height, involucre bracts not being striate-
nerved, and dist; i;ution at high altitudes in the mountains (Massey of al.1983). Vegetative portions of the
plant may emerge in Juiy and persist through October (Massey of a/. 1983). ,Flowering occurs from fate
July to September (Kral 1983).
Blue Ridge goldenrod is found on rocky summits above approximately 4000 feet (1200 meters} elevation in
the mountains. Typically found in full sun, this plant may be found rooted in fine sands that have
accumulated in cracks and pockets of granitic rocks or bluff ledges, or associated with grasses and sedges
on grass balds contiguous to rock outcrops {Kral 1983}. In North Carolina, the current distribution may be
restricted to Avery and Mitchell Counties (Amoroso and Weakley 1995). NHP records do not indicate that
Blue Ridge goldenrod has been documented within 2.0 mi (3.2 kilometers) of the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to affect Blue Ridge goldenrod due to
the absence of suitable habitat within the low elevation (approximately 2040 feet (620 meters))
study corridor. NO EFFECT
Virginia Spiraea - Vrginia spiraea is a deciduous, colonial shrub that averages 1 to 3 meters (3 to 10 ft) in
height, but may reach heights of 13 feet (4 meters}. Its short-stalked leaves are alternate, nearly toothless,
and narrowly elliptic with a pointed tip (Radford et a1.1968). Numerous small, white, 5-petaled flowers are
produced on terminal clusters in June to July. Dried corymbs often persist through winter. Seed production
is reported to be sporadic and most colonies are believed to arise from downstream dispersal and
establishment of fragments of horizontal rootstock (Porter and Wieboldt 1991).
Endemic to the southern Appalachians, Virginia spiraea is restricted to disturbance-prone riverine areas,
specifically along scoured hanks of high gradient streams, meander scrolls, point bars, natural levees, and
braided features of Power stream reaches {Porter and Wieboldt 1991). Disturbance is required for removal
of -woody competitors and to aid in establishment of colonies. NHP files indicate that Virginia spiraea has
been documented on the Cane River more than 5.0 mi (8.0 kilometers) upstream from the confluence with
the North Toe River. NHP records do not indicate that Virginia spiraea has been documented in the North
Toe River within 2.0 mi (3.2 kilometers) of the project bridge.
BIOLOGICAL CONCLUSION: The subject project was visited by NCDOT biologists May 8, 2003.
The potential impact zones were visually examined for the presence of this species by walking
along proposed construction area. No spiraea p{ants were found within the project study area
surveyed. It can be concluded that project construction will have no impact on the Virginia spiraea.
NO EFFECT
Rock Gnome Lichen -The rock gnome lichen is a small, squamulose (strap-like) lichen in the reindeer
moss (lichen) family. This species is similar to squamulose lichens in the genus Ciadortia by having
terminal portions of its strap-like lobes that are blue-gray on the upper surface and shiny-white on the lower
surface; rock gnome lichen differs from these other lichens by having blackened lobe bases.. The lichen
grows nearly parallel to the rock surface to which it is attached, but the tips curl up to a near vertical
orientation. Reproduction appears to be asexual, with colonies spreading clonally. Rock gnome lichen is
21

typically found growing in association with a distinctively colored, n:ddish-brown moss {Andreaea)
{Murdock 1993).
The rock gnome I'~ctren is endemic to the mountains of North Carolina and Tennessee. Most populations
occur above approximately 5000 feet {1525 meters) in elevation in areas subject to frequent fog cover, but
the species has been found at lower elevations in deep gorges where a similarly high humidity regime is
present. Rock gnome lichen typically occurs on vertical rock faces subject to intermittent seepage
(Murdock 1993). NHP rncords do not indicate that rock gnome lichen has been documented within 2.0 mi
(3.2 kilometers) of the project bridge.
BIOLOGICAL CONCLUSION: This project is not expected to affect rock gnome lichen due to the
absence of suitable habitat within the low elevation (approximately 2040 feet (fi20 meters)) study
corridor. NO EFFECT
Space- Fir Moss Spider -The spruce-fir moss spider is currently known from only four locations. There
are three sites in North Carolina (one in AverylCaldwell Counties and two in Swain County) and one in
Tennessee (Sevier County). At this time, only the population in AverylCaldwell Counties in North Carolina
appears to be stable. The other two populations in North Carolina are very small, with only one individual
found at each in recent searches (Harp 1992). The Tennessee population has been considered healthy in
the past, but is currently declining due to habitat loss.
This spider is typically found in damp moss and liverwort mats growing on rocks in well shaded,
mature,,high elevation Fraser fir and red spruce forests (Harp 1992}. This spider cannot tolerate
desiccation. The spider constructs its web under the moss, at the interface with the rock. Webs are tube-
shaped, thin-walled,.and generally flat with short side branches. Little is known about the diet of the
spruce-fir moss spider, but springtails (Osier Collembola) are abundant in the moss mats and probably
constitute most of the prey (Harp 1992).
BIOLOGICAL CONCLUSION: This project is not expected to affect the spruce-fir moss spider
due to the absence of suitable habitat within the low elevation (approximately 2040 feet (620
meters)) study corridor: NO EFFECT
Federa! species of concern -The February 24, 2003 FWS List also includes a category of species
designated as "Federal species of concem" (FSC). The FSC designation provides no federal protection

NHP fifes do not document any FSC within the study corridor, nor in the North Toe or Noiichucky River
within 3.2 kilometers upstream or downstream ftom the study corridor. Two FSC species, olive darter and
heilbender, have been documented. within the lower 2.0 mi (3.2 kilometers) reach of the Cane River.
State Protected Species
Plant and anima! species which are on the North Carolina state list as Endangered (E), Threatened (T), or
Special Concern (SC} receive limited protection under the North Carolina Endangered Species Act (G.S.
113-331 of seq.} and the North Carolina Plant Protection Act of 1979 (G.S.106-202 et seq.). .
23

NHP records indicate that the state-Special Concern wavy-rayed iampshell (Lampsilis fasciola) has been
documented in the North Toe River within or adjacent to the study corridor. Two state-listed fish species,
sharphead darter (Efheostoma acuficeps) and logperch (Percina caprodes), have been documented in the
North Toe River between 0.8 and 1.0 and 2.3 mi (3.7 kilometers) upstream from the study corridor.
Suitable habitat for these species may be present in the study corridor. Sharphead darter and two other
state-listed fish species, the state-Endangered. stonecat (Noturus flavus} and state-Threatened striped
shiner (Luxifus chrysocephalus), which have been documented in the lower 3.6 miles (5.8 km) reach of
Cane Creek and which is located a short distance downstream from study corridor, may be expected to
occur within the study corridor as well. No terrestrial state-fisted species have been documented within 2.0
mi (3.2 kilometers) of the study corridor. Impacts to these species can be alleviated by bridging of the main
river channel.
National Forest Lands
Portions of the study corridor north of the North Toe River and west of SR 1340 are located on private
holdings within established boundaries of the Pisgah National Forest. No Nationa{ Forest Lands will be
affected.
IX. CULTURAL RESOURCES
This project is subject to compliance with Section 106 of the Natural Historic Preservation- Act of 1966, as
amended, implemented by the Advisory Council on Historic Preservation's Regulations for Compliance with
Section 106, codified at 36 CFR Part 800. Section 106 requires that if a federally funded, licensed, or
permitted project has an effect on a property fisted in or eligible for the National Register of Historic Places,
the Advisory Council on Historic Preservation be given an opportunity to comment. Pursuant to Section
106, comments were requested from the Deputy State Historic Preservation Officer (SHPO) and were
received on March 3,1997 (see Appendix}.
Based on comments received from the SHPO, it is unlikely that any archaeological resources which may be
eligible for inclusion in the National. Register of Historic Places will be affected by this project. Therefore,
no archaeological investigations will be conducted for this project.
There are no structures of historic or architectural importance located within the area of potential effect of
this project.
X. ENVIRONMENTAL EFFECTS
Replacement of Bridge No. 143 will not have an adverse effect on the quality of the human or natural
environment if current NCDOT standards and specfications are implemented. A section seven consultation
will be required concerning the Appalachian Elktoe mussel species following completion of this document.
The project should have an overall positive impact due to the improvement of existing poor bridge
conditions and substandard roadway geometries (one-lane bridge). The new bridge and approaches will
result in safer traffic operations in the project area.
This project is not in conflict with any plan., existing land use, or zoning regulation. No Significant change in
land use is expected to result from replacement of Bridge No. 143.
24

No adverse impact on families or communities is anticipated with the .implementation of the preferred
alternative (Alternate B). No relocatees are expected with implementation of Attemate B.
This project will not have an adverse effect on any prime, important or unique farmlands, therefore it is
exempt from the Farmland Protection Policy Act.
No publicly owned parks, recreational facilities, or wildlife and waterfowl refuges of national, state or local
significance in the immediate vicinity of the project will be impacted.
No geodetic survey markers will be impacted by this project.
No adverse effects to air quality are expected as a result of this project. This project is an air quality
`neutral" project, so it is not required to be included in the regional emissions analysis (if applicable) and a
project level CO analysis is not required. If vegetation or wood debris is disposed of by open burning, it
shall be done in accordance with applicable local laws and regulations of the North Carolina State
Implementation Plan (SIP) for air quality in compliance with 15 NCAC 2D.0520. This evaluation completes
the assessment requirements for air quality, no additiona! reports are required.
Ambient noise levels may increase during the construction of this project, however this increase will be only
temporary and usually confined to daylight hours. There should be no notable change in traffic volumes
after this project is complete. Therefore, this project will have no adverse effect on existing noise levels.
Noise receptors in the project area will not be impacted by this project. This evaluation completes the
assessment requirements for highway noise setforth in 23 CFR Part 772. No additional reports are
required.
The preferred alternative will not adversely affect the existing floodpfain and flow characteristics of the
North Toe River.
This project is being processed as a Federal Categorical Exclusion due to its limited scope and lack c`
signifcant environmental consequences. Based on the assessment of the existing human and natural
enviror)ment, it is concluded that no significant adverse environmental- effect will result from the
replacement of Bridge No. 143.

Re: Permit Application for proposed Replacement of Bridge No. 143 in Mitchell and Yancey
Counties
DWQ No. 040933, TIP No. B-2848
Dear Dr. Thorpe:
The Division of Water Quality has reviewed your submittal''for a 401 Water Quality Certification
for the aforementioned project. Review of your application revealed it lacking necessary
information required for making an informed permit decision. The permit application was
deficient in the following areas:
• The NC Department of Transportation (DOT) has failed to detail the permanent impacts of the
proposed bridge bents to be located in the North Toe River. DWQ cannot issue a 401Water
Quality Certification based on the current application due to DOT's failure to demonstrate
minimisation of impacts in accordance with 15A NCAC 2H .0506(g).
Therefore, pursuant to 15A NCAC 2H .0507(a)(5), we will have to place the permit application
on hold until we are supplied the necessary information. Furthermore, until the information is
received by the NC Division of Water Quality; we request (by copy of this letter) that the US
Army Corps of Engineers place the permit application on hold.
Hopefully, we can work together to expedite the processing of your permit application. If you
have any questions or require additional information, please contact John Hennessy at 919-733-
5694.

ATTN: Mr. Steve Lund
NCDOT Coordinator
Dear Sir:
SUBJECT: Nationwide 23 and 33 Permit Applications. Replacement of
Bridge No. 143 over the North Toe River on SR 1304 (Tipton Hill
Road/Ray Road), Mitchell and Yancey Counties. Federal Aid
Project No. BRZ-1304(4), State Project No. 8.2880401, TIP
Project No. B-2848.
The NC Department of Transportation (NCDOT) proposes to replace existing Bridge No.
143 over the North Toe River on SR 1304 (Tipton Hill Road/Ray Road). The project
involves replacing bridge no. 143 with amulti-span two-lane, 350-foot (108 meters) long
bridge over the North Toe River (DWQ Index # 7-2-(27.7), Class "C Tr"). The bridge
will be replaced approximately 50-feet (15.2 meters) downstream (northwest) of the
existing structure. The bridge will have a clear roadway of 24-feet (7.2 meters) in width,
including two travel lanes totaling 20-feet (6.0 meters) in width and a 2-foot (6.0 meters)
shoulder on each side of the bridge.
The existing bridge will remain in place to maintain traffic during construction and will
be removed when construction is complete.
IMPACTS TO WATERS OF THE UNITED STATES
No permanent impacts to Waters of the United States, in the form of wetlands or surface
waters, are anticipated as a result of project construction.

The existing, Bridge -No: 143 is a one-lane structure with five spans totaling 367-feet
(11 ~~'9 iYeters). The superstructure consists of a reinforced concrete deck, an asphalt
wearing surface, and metal guardrails. The substructure consists of reinforced concrete
earth-filled spandrel arches, reinforced concrete abutments, and reinforced concrete piers.
The depth from roadway crown to the streambed is approximately 28-feet (8.5 meters).
Guidelines followed for the construction phase of the project are in accordance with the
NCDOT Best Management Practices for Protection of Surface Waters and the Tennessee
Valley Authority (TVA) Water Management Standard Conditions.
BRIDGE CONSTRUCTION
Bridge No. 143 will be a three span, steel girder, cast-in-place concrete deck
superstructure. The substructure will include drilled piers for two interior bents.
Construction of the bridge will require the need for a temporary causeway/workpad.
TEMPORARY CAUSEWAYS/WORKPADS
There will be 0.257 acres of temporary impacts in the North Toe River from the
construction of a temporary bridge workpad for the construction of Bridge No. 143.
Temporary workpads of Class II Rip Rap topped with 1-inch of Class I Rip Rap will be
required to provide access to the site for construction equipment.
No permanent fill will result from the subject activity. The materials used as temporary
fill in the construction of the rock causeways, will be completely removed. The entire
causeway footprint shall be returned to the original contours and elevations after the
purpose of the causeway has been served. After the causeways are no longer needed, the
contractor will use excavating equipment to remove all materials. The causeway is
estimated to be in the water for about 8 months. All causeway material will become the
property of the contractor. The contractor will be required to submit a reclamation plan
for removal of and disposal of all materials off-site.
FEDERALLY-PROTECTED SPECIES
Plants and animals with federal classifications of Endangered, Threatened, Proposed
Endangered, and Proposed Threatened are protected under Endangered Species Act §§7
and 9. As of January 29, 2003, the US Fish and Wildlife Service (USFWS) lists 13
federally protected species for Mitchell and Yancey Counties (Table 1). Other than the
Appalachian elktoe (Alasmidonta raveneliana), the biological conclusions of "No Effect"
were reached for all listed. Currently a biological assessment (BA) is being produced for
the Appalachian elktoe that will closely follow this permit application.

REGULATORY APPROVALS
Section 404 Permit: It is anticipated that the construction of the temporary causeways will
be authorized under Section 404 Nationwide Permit 33 (Temporary Construction Access
and Dewatering). We are, therefore, requesting the issuance of a Nationwide Permit 33
authorizing construction of the causeway. All other aspects of this project are being
processed by the Federal Highway Administration as a "Categorical Exclusion" in
accordance with 23 CFR § 771.115(b). The NCDOT requests that these activities be
authorized by a Nationwide Permit 23 (FR number 10, pages 2020-2095; January 15,
2002).
Section 401 Permit: We anticipate 401 General Certifications number 3403 and 3366 will
apply to this project. In accordance with 15A NCAC 2H .0501(a) we are providing two
copies of this application to the North Carolina Department of Environment and Natural
Resources, Division of Water Quality, for their records.
We anticipate that the Corps of Engineers will request comments from the North Carolina
Wildlife Resources Commission (NCWRC) prior to authorization. By copy of this letter
and attachment, NCDOT hereby requests NCWRC review. NCDOT requests that
NCWRC forward their comments to the Corps of Engineers.

Division of Water Quality for projects involving greater than or equal to one acre of impacts to
Page 5 of 8

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 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
httn://h2o.enr.state.nc.us/ncwetlands/strmgide html.
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/lineaz 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.

Services Section, at (9101251-4728
All of the bridges, except for those in Burke and McDowell Counties, are within the
planning jurisdiction of the U.S. Army Corps of Engineers (USA,CE), ~;ashville Cistrict.
These bridges are located within counties which participate in the National Flood
Insurance Program (NFIP). From the various Flood Insurance Rate Maps (FIRMs), it
appears that both approximate study and detail study streams are involved. (Detail
study streams are those with 100-year flood elevations determined and [generally] a
floodway defined). A summary of flood plain information pertaining to these bridges is
contained in the following table. The FIRMs are from the county flood insurance study
unless otherwise noted.

1. FLOOD PLAINS: [Continued)
Reference is made the Federal Emergency Management Agency's (FEMA's)
°Procedures for'No Rise' Certification for Proposed Developments in Regulatory
Floodways', copies of which have been provided previously to your office. The project
should be designed to meet the requ~ramsnts of the N; !P, Gdministered by FEMA, and
be in compliance with all local ordinances. The engineering point of contact for the
NFIP in this FEMA region is Ms. Be{ Marquez, who may be reached at [phone].
Specific questions pertaining to community flood plain regulations or developments
should be referred to the local building official.
AI! of the affected counties, except for Burke and McDowell Counties, are within
the planning jurisdiction of the USACE, Nashville District, and the Tennessee Valley
Authority (TVA) with respect to any construction or development involving the flood
plains. The Nashville District does not currently have projects that would be affected by
the proposed project. Mr. Jamie James may be contacted at {615) 736-5948 for further
information and comments from the Nashville District. Flood plain concerns are
normally addressed within the TVA Section 26a permitting process. A 26a permit is
required for all construction or development involving streams or flood plains in the
Tennessee River drainage basin. Mr. Roger Mitstead at 1423) 632-6115 should be
contacted for information on the TVA 26a permitting process.
2. WATERS AND WETLANDS: POC • Asheville Field Office, Reyulatorv Branch
[Individual POC's are fisted following the comments.
All work restricted to existing high ground will not require prior Federal permit
authorization. However, .Department of the Army permit authorization pursuant to
Section 404 of the Clean Water Act of 1977, as amended, will be required for the
discharge of excavated or fill material in. waters of the United States or any, adjacent
and/or isolated wetlands in conjunction with your proposed bridge replacements,
including disposal of construction debris.

"".otlfication of Start of ~vtudy ai d Regi.iest for Project liipVi, oridge Replacement Group
XII (Western North Carolina"
2. WATERS AND WETLANDS: (Continued)
The replacement of these bridges may be eligible for nationwide permit
authorization [33 CFR 330.5{a)(23)] as a Categorical Exclusiol, depending upon the
amount of jurisdictional wetlands to be impacted by a project and the construction
technivues utilized. Please be reminded that, prior to utifizction of natior;~zida permits
within any of the 25 designated mountain trout counties, the North Carolina Department
of Transportation should provide a letter of notification to the Asheville Regulatory Field
Office and the appropriate North Carolina Wildlife Resources Commission office with
reference to impacts to mountain trout water habitat, The mountain trout designation
carries discretionary authority for the utilization of nationwide permits. In addition, any
jurisdictional impacts associated with temporary access roads or detours, cofferdams,
or otheF dewatering structures should be addressed in the Categorical Exclusion
documentation in order to be authorized by Nationwide Permit No. 23 {NWP 23). If
such information is not contained within the Categorical Exclusion documentation, then
other DA permits may be required prior to construction activities.
Where possible, the bridges should be replaced with bridges, and impacts to the
channel and wetlands should be avoided and/or minimized.. Although these projects
may qualify for NWP 23 as a categorical exclusion, the project planning report should
contain sufficient information to document that the proposed activity does not have
mare than a minimal individual or cumulative impact on the aquatic environment.
Accordingly, we offer the following comments and recommendations to be addressed in
the planning report:
a. The report should contain the amount of permanent and temporary impacts #o
waters and wetlands as well as a description of the type of habitat that will be affected.
b. Off-site detours are always preferable to on-site (temporary) detours in
wetlands. If an on-site detour is the recommended action, justification should be
provided.
c. Project commitments should include the removal of all temporary fills from
waters and wetlands. In addition, if undercutting is necessary for temporary detours,
the undercut material should be stockpiled to be used to restore the site.

WATER MANAGEMENT STANDARD CONDITIONS
For ail off-reservoir requests, a condition should be placed in any general pemut or letter of no jurisdiction to
inform the applicant of the need to comply with local floodplain regulations that may be in effect The condition
should read:
You should cantact your local government official(s) to ensure that this facility complies with all applicable
local fioodpiain regulations.
The fotlovsrng conditions sl-~auki bE used for all bridge and culvert approvals:
1. Best Management and Best Engineering Practices will be used to prevent the introduction of soil or any
other poqutants into surface or groundwaters, inducting but not limited to the following:
a. installing cofferdams and/or sift control structures between construction areas and the streams prior
to any soil-disturbing demoiitioNconstruction activity, and clarifying all water that is trapped or
accumulates behind these devices to meet water quality criteria before it is returned to the stream.
Cofferdams must be used wherever construction activity is at or below water elevation.
b. Removing demolfion products and construction by-products from the site for recycling, if practicable,
or proper disposal outside of a 100-year ftoodplain.
c. Minimizing removal of vegetation.
d. Keeping equipment out of streams {i.e., performing work 'in the dry').
e. Keeping equipment off stream banks to the degnre practicable.
f. Using erosion control structures around any material stockpile areas.
g. Removing, redistributing, and stabilizing {with vegetation) all sediment which accumulates behind
cofferdams and sift control structures.
h. Using vegetation (versus shot rock or riprap) wherever practicable and sustainable. to stabilize
streambanks and floodptain areas. These areas will be stabilized as soon as practicable, using
" either an appropriate seed mixture that includes an annual {quick cover) as weN as 1 or 2 perennial
legumes and 1 or 2 perennial grasses, or equivalent sad. In certain periods of the year, this will
require initial p4~nting of a quick cover annual oNy, to be followed by subsequent establishment of
the perennials. Seed and soil will be protected as appropriate with erosion control netting and/or
mulch, and provided adequate moisture. Strearnbank and floodplain areas will also be pemianeMly
stabilized with native woody plants, to include trees wherever practicable and sustainable and
consistent with other n:guiatory agency specrf' nations.
i. Applying ciean/shaken riprap or shot rock (where needed at waterlbank interface) over a water
permeabie/soil impermeable fabric or geotextiie and in such a manner as to avoid stream
sedimentation or disturbance.
j. Avoiding spilling concrete, or other substances or materials; into the streams.
k. Designing/constnrcting any instream piers in such a manner as to discourage river scouring or
sediment deposition.
!. Bank shoreline, and floodplain stabilization will be permanently maintained in order to prevent
erosion, protect water quality, and preserve aquatic habitat.
m. Culverts are constructed in phases, and adequate streambank protection measures are employed,
such that the diverted streamflow is handled without creating streambank or streambed
erosioNsedimentation and without preventing ftsh passage.

Appendix F
2 Concrete box culverts and pipe culverts (and their extensions) must create/maintain velocities and flow
patters which offer refuge for fish and other aquatic Gfe, and allow passage of indigenous fish species,
under all flow conditions. Culvert floor slabs and pipe bottoms must be buried aL least one foot below
streambed elevation, and fiiEed with naturaNy-occurring streambed materials. If geobgic conditions do not
allow burying the floor, it nutst be otherwise designed to allow passage of indigenous fish species under all
flow conditions.
3. AI{ natural stream values ('rnduding equivalent energy dissipation. elevations, and velocities; riparian
vegetation; riffiefpoot sequerx;irrg; habitat suitable for frsh and other aquatic life] must be provided. ai all
stream modification sites. Tf~is must be accomplished using a combination of rock and bioengineering,

MEMORANDUM
To: Ms. Cindy Sharer, P.E., NCDOT, Planning & Environmental
From: Cyndi Bell, NC Division of Water Quality (~. ~„~
Subject: Water Quality Checklist for Bridge Replacement Projects
Reference your correspondence dated February 10, 1997, in which you requested preliminary comments
concerning nine bridge replacement projects. The Division of Water Quality requests that NCDOT
consider the following generic environmental commitments for design and construction of bridge
replacements:
A. DWQ requests that DOT strictly adhere to North Carolina regulations entitled "Design Standards
in Sensitive Watersheds" (15A NCAC 04B ..0024) throughout design and conswction far this
project in the area that drains to streams having WS (Water Supply), ORW (Outstanding
Resource Water), HQW (High Quality Water), B (Body Contact), SA (Shellfish Water) or Tr
(Trout Water) classifications wprotect existing uses.
B. DWQ requests that bridges be replaced on existing Location with road closure, when practical. If
an on-site detour is necessary, remediation measures in accordance with DWQ requirements for
Genera1401 Certification 2726/Nationwide Permit No. 33 (Temporary Construction, Access and
Dewatering) must be followed.
G DWQ requests that hazardous spill etch basins be installed at any bridge crossing a stream
classified as HQW or WS (Water Supply). The number of catch basins .installed should be
determined by the design of the bridge, so that runoff would enter said basin(s) rather than
directly flowing inw the stream.
D. To the maximum extent practicable, DOT should not install the bridge bents in the creek.
E. Wetland impacts should be avoided (including sediment and erosion control
swcwres/measures) to the maximum extent practical. If this is not possible, alternatives that
minimize wetland impacts should be chosen. Mitigation for unavoidable impacts will be
required by DWQ if impacts exceed one acre. Smaller impacts may require mitigation by the
U.S. Army Corps of.Engineers.
F. Borrow/waste areas should not be located. in wetlands. It is likely that compensatory mitigation
will be required if wetlands aze.impacted by waste or borrow.
G. DWQ prefers replacement of bridges with bridges. if the new strucwre is to be a culvert, it
should be countersunk to allow unimpeded fish passage through the crossing.

H. If foundation test borings will be required, this should be noted in the document. Geotec6nical
work is approved Hader General 401 Certification Number 3027/Nationwide Permit No. 5 for
Survey Activities. Written contaurence from the North Carolina WildlifeResources Commission
and U.S. Army Corps of Engineers is required in designated mountain trout counties.
I. If this projeU is processed as a Categorical Exclusion, NCDOT is reminded that mitigation will
be required if wetland impacts exceed one acre, in accordance with DWQ Wetland Rules { 15A
NCAC ZH.0506 (h)(2))
The aaached table has been prepared by DWQ for your assistance in studying the systems involved in
these bridge replacements. This information includes the DWQ Index Number, DWQ Stream
Classification, river basin, and preliminary comments for each crossing. Please note that National
Wetland Inventory (NWI) map references are not to be replaced by onsite wetland determinations by
qualified biologists.
Thank you for your request for DWQ input. DOT is reminded that issuance of a 401 Water Quality
Certification requires satisfaction of wares quality concerns, to ensure that water quality standards are met
and designated uses are not lost or degraded. Questions regarding the 401 Certification or other water
quality issues should be directed to Cyndi Bell at (919) 733-.1786 in DWQ's Water Quality Environmental
Sciences Branch. ~ .

kffrey J. Craw, Director
Thank you for your letter of February 10, 1997, concerning the above project.
We have conducted a search of our maps and files and have located the following
structures of historical or architectural importance within the general area of the project:
Robert Griffith House. North side of SR 1304, 0.1 mile east of junction with SR
1320, Huntdale Community. This property was placed on the state study list on
January 8, 1987.
We look forward to meeting with an architectural historian from the North Carolina
Department of Transportation to review the aerial and photographs of the project area so
we can make our survey recommendation.
There are no known archaeological sites within the proposed project area. Based on our
present knowledge of the area, it is unlikely that any archaeological resources which may
be eligible for inclusion in the National Register of Historic Places will be affected by the
project construction. We, therefore, recommend that no archaeological investigation be
conducted in connection with this project.
The above comments are made pursuant to Section ~ 06 of the National Historic
Preservation Act and the Advisory Council on Historic Preservation's Regulations for
Compliance with Section 106 codified at 36 CFR Part 800.
Thank you for your cooperation and consideration. If you have questions concerning the
above comment, please contact Renee Giedhill•Earley, environmental review coordinator, at
919/733-4763.

Subject: Notification of start of study and request for project input, Bridge Replacement Group
" XII (Western North Cazolina), Tn' Numbers B-2I S0, B-2848, B-2927, B-3000,
B-3118, B-3121, B-3189, B-3205, B-3206.
This is the response of the U. S. Fish and Wildlife Service (Service) to your letter of February 10,
1997, requesting input for the subject bridge replacement projects. The following comments are
provided in accordance with the provisions of the Fish and Wildlife Coordination Act, as
amended (16 U.S.C. 661-667e), and Section 7 of the Endangered Species Act of 1973, as
amended (16 U.S.C. 1531-1543) (Act).
The Service is particularly concerned about the potential impacts the proposed projects could
have on federally listed species and on Federal species of concern and the potential impacts to
stream and wetland ecosystems within the azea.
The Service concurs with the decision to prepaze categorical exclusion documents for bridge
replacement projects B-2150, B-2927, B-3000, B-3118, B-3121, B-3189, B-3205, B-3206,
provided the following measures aze implemented. to minimize impacts to aquatic resources:
(1) riparian vegetation should be maintained wherever possible, especially lazge trees; (2) if any
riparian areas aze disturbed, they should be revegetated with native species as soon as possible
after construction in order to minimize nmoff and lessen the impacts associated with "bare
banks" (decrease in nutrient input, temperature changes, flow changes, sediment filtration, etc.);
(3) stringent erosion control measures should be implemented during ail construction activities in
order to minimize downstream effects; and (4) construction should be accomplished so that wet
concrete does not contact water entering or flowing in the stream. These measures will reduce
the likelihood of aquatic impacts associated with. the bridge construction.

~~ "~~
The Service does not agree that bridge replacement project B-2848 should be categorically
excluded from further envimnmental study due to the fact that the endangered Appalachian
elktoe (Alasmidonta raveneliana) is known to occur in the North Toe River in the immediate
vicinity of the proposed project. The North Carolina Department of Transportation should work
closely with the Service to incorporate sufficient measures and monitoring, in addition to those
already mentioned, to avoid impacts to this endangered mussel. Otherwise, if it is determined
that the proposed project may affect the Appalachian ellctoe, formal consultation, as directed by
the Act, would have to be initiated with our office.
We have reviewed our files and believe the environmental document should evaluate possible
impacts to the following federally listed species and/or Federal species of concern:
Virginia spires (Spires virginiana) (Threatened) -This plant species is found
along streams on sandbars and stream banks.
Olive darter (Percina squamata) (Federal species of concern) -This small fish is
found in deep swift rapids and runs neaz boulders.
Hellbender (Cryptobranchus alleganiensis) (Federal species of concern) -This
amphibian inhabits clear-flowing water areas with large flat rocks.
The presence or absence of the above-mentioned species in the project impact area should be
addressed in any environmental document prepared for this project. Please note that the legal
responsibilities of a Federal agency or their designated non-Federal representative with regazd to
federally Listed endangered and threatened species under Section 7 of the Act aze on file with the
Federal Highway Administration. Also, please note that Federal species of concern are not
legally protected under the Act and are not subject to any of its provisions, including Section 7,
unless they are formally proposed or listed as endangered or threatened. We aze including these
species in our response in order to give you advance notification and to request your assistance in
protecting them.
.Additionally, the Service believes the environmental document(s) for the proposed projects
should address the following issues: (1) any proposed temporary bridges or structures associated
with the bridge replacements; (2) any special measures proposed to mininize sedimentation
during construction; and (3) any measures that will be implemented to minimize impacts to fish
and wildlife habitat (e.g., protecting riparian vegetation whenever possible).
We appreciate the opportunity to provide these scoping comments and request that you keep us
informed as to the progress of these projects. in any future correspondence concerning this
matter, please reference our Log Number 42-97-077.
Sincerely,

SUBJECT: Nationwide 23 and 33 Permit Applications. Replacement of
Bridge No. 143 over the North Toe River on SR 1304 (Tipton Hill
RoadlRay Road), Mitchell and Yancey Counties. Federal Aid
Project No. BRZ-1304(4), State Project No. 8.2880401, TIP
Project No. B-2848.
The NC Department of Transportation (NCDOT) proposes to replace existing Bridge No.
143 over the North Toe River on SR 1304 (Tipton Hill Road/Ray Road). The project
involves replacing bridge no. 143 with amulti-span two-lane, 350-foot (108 meters) long
bridge over the North Toe River (DWQ Index # 7-2-(27.7), Class "C Tr"). The bridge
will be replaced approximately 50-feet (15.2 meters) downstream (northwest) of the
existing structure. The bridge will have a clear roadway of 24-feet (7.2 meters) in width,
including two travel lanes totaling 20-feet (6.0 meters) in width and a 2-foot (6.0 meters)
shoulder on each side of the bridge.
The existing bridge will remain in place to maintain traffic during construction and will
be removed when construction is complete.
IMPACTS TO WATERS OF THE UNITED STATES
No permanent impacts to Waters of the United States, in the form of wetlands or surface
waters, are anticipated as a result of project construction.

BRIDGE DEMOLITION
The existing Bridge No. 143 is a one-lane structure with five spans totaling 367-feet
(111.9 meters). The superstructure consists of a reinforced concrete deck, an asphalt
wearing surface, and metal guardrails. The substructure consists of reinforced concrete
earth-filled spandrel arches, reinforced concrete abutments, and reinforced concrete piers.
The depth from roadway crown to the streambed is approximately 28-feet (8.5 meters).
Guidelines followed for the construction phase of the project are in accordance with the
NCDOT Best Management Practices for Protection of Surface Waters and the Tennessee
Valley Authority (TVA) Water Management Standard Conditions.
BRIDGE CONSTRUCTION
Bridge No. 143 will be a three span, steel girder, cast-in-place concrete deck
superstructure. The substructure will include drilled piers for two interior bents.
Construction of the bridge will require the need for a temporary causeway/workpad.
TEMPORARY CAUSEWAYS/WORKPADS
There will be 0.257 acres of temporary impacts in the North Toe River from the
construction of a temporary bridge workpad for the construction of Bridge No. 143.
Temporary workpads of Class II Rip Rap topped with 1-inch of Class I Rip Rap will be
required to provide access to the site for construction equipment.
No permanent fill will result from the subject activity. The materials used as temporary
fill in the construction of the rock causeways, will be completely removed. The entire
causeway footprint shall be returned to the original contours and elevations after the
purpose of the causeway has been served. After the causeways are no longer needed, the
contractor will use excavating equipment to remove all materials. The causeway is
estimated to be in the water for about 8 months. All causeway material will become the
property of the contractor. The contractor will be required to submit a reclamation plan
for removal of and disposal of all materials off-site.
FEDERALLY-PROTECTED SPECIES
Plants and animals with federal classifications of Endangered, Threatened, Proposed
Endangered, and Proposed Threatened are protected under Endangered Species Act §§7
and 9. As of January 29, 2003, the US Fish and Wildlife Service (USFWS) lists 13
federally protected species for Mitchell and Yancey Counties (Table 1). Other than the
Appalachian elktoe (Alasmidonta raveneliana), the biological conclusions of "No Effect"
were reached for all listed. Currently a biological assessment (BA) is being produced for
the Appalachian elktoe that will closely follow this permit application.

REGULATORY APPROVALS
Section 404 Permit: It is anticipated that the construction of the temporary causeways will
be authorized under Section 404 Nationwide Permit 33 (Temporary Construction Access
and Dewatering). We are, therefore, requesting the issuance of a Nationwide Permit 33
authorizing construction of the causeway. All other aspects of this project are being
processed by the Federal Highway Administration as a "Categorical Exclusion" in
accordance with 23 CFR § 771.115(b). The NCDOT requests that these activities be
authorized by a Nationwide Permit 23 (FR number 10, pages 2020-2095; January 15,
2002).
Section 401 Permit: We anticipate 401 General Certifications number 3403 and 3366 will
apply to this project. In accordance with 15A NCAC 2H .0501(a) we are providing two
copies of this application to the North Carolina Department of Environment and Natural
Resources, Division of Water Quality, for their records.
We anticipate that the Corps of Engineers will request comments from the North Carolina
Wildlife Resources Commission (NCWRC) prior to authorization. By copy of this letter
and attachment, NCDOT hereby requests NCWRC review. NCDOT requests that
NCWRC forward their comments to the Corps of Engineers.

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
Page 5 of 8

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 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
httn://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 separate sheet if more space is needed.

MEMORANDUM
To: Ms. Cindy Shazer, P.E., NCDOT, Planning & Environmental
.From: Cyndi Bell, NC Division of Water Quality G (~~
Subject: Water Quality Checklist for Bridge Replacement Projects
Reference your correspondence dated February 10, 1997, in which you requested preliminary comments
concerning nine bridge replacement projects. The Division of Water Quality requests that NCDOT
consider the following generic environmental commitments for design and construction of bridge
replacements:
A. DWQ requests that DOT strictly adhere to North Carolina regulations entitled "Design Standazds
in Sensitive Watersheds" (15A NCAC 04B .0024) throughout design and construction for this
project in the area that drains to streams having WS (Water Supply), ORW (Outstanding
Resource Water), HQW (High Quality Water), B (Body Contact), SA (Shellfish Water) or Tr
(Trout Water) classifications to protect existing uses.
B. DWQ requests that bridges be replaced on existing location with road closure, when practical. If
anon-site detour is necessary, remediation measures in accordance with DWQ requirements for
Genera1401 Certification 2726/Nationwide Permit No. 33 (Temporary Construction, Access and
Dewatering) must be followed.
C. DWQ requests that hazardous spill catch basins be installed at any bridge crossing a stream
classified as HQW or WS (Water Supply). The number of catch basins installed should be
determined by the design of the bridge, so that runoff would enter said basin(s) rather than
directly flowing into the stream.
D. To the maximum extent practicable, DOT should not install the bridge bents in the creek.
E. Wetland impacts should be avoided (including sediment and erosion control
structures/measures) to the maximum extent practical. If this is not possible, alternatives that
minimize wetland impacts should be chosen. Mitigation for unavoidable impacts will be
required by DWQ if impacts exceed one acre. Smaller impacts may require mitigation by the
U.S. Army Corps of Engineers.
F. Borrow/waste areas should not be located in wetlands. It is likely that compensatory mitigation
will be required if wetlands are impacted by waste or borrow.
G. DWQ prefers replacement of bridges with bridges. If the new structure is to be a culvert, it
should be countersunk to allow unimpeded 6sh passage through the crossing.

H. If foundation test borings will be required, this should be noted in the document. Geotechnical
work is approved under Genera1401 Certification Number 3027/Nationwide Permit No. 6 for
Survey Activities. Written concurrence from the North Carolina Wildlife Resources Commission
and U.S. Army Corps of Engineers is required in designated mountain trout counties.
I. If this project is processed as a Categorical Exclusion, NCDOT is reminded that mitigation will
be required if wetland impacts exceed one acre, in accordance with DWQ Wetland Rules { 15A
NCAC 2H.0506 (h)(2)}.
The attached table has been prepared by DWQ for your assistance in studying the systems involved in
these bridge replacements. This information includes the DWQ Index Number, DWQ Stream
Classification, river basin, and preliminary comments for each crossing. Please note that National
Wetland Inventory (NWI) map references are not to be replaced by onsite wetland determinations by
qualified biologists.
Thank you for your request for DWQ input. DOT is reminded that issuance of a 401 Water Quality
Certification requires satisfaction of water quality concerns, to ensure that water quality standards are met
and designated uses are not lost or degraded. Questions regazding the 401 Certification or other water
quality issues should be directed to Cyndi Bell at [phone] in DWQ's Water Quality Environmental
Sciences Branch.

Subject: Nationwide 23 and 33 Permit Applications
Replacement of Bridge No. 143 over the North
Toe River, TIP Project No. B-2848
Dear Mr. Lund:
After review of the referenced permit application, the Division Hof Water Quality (DWQ) finds that the
impact analysis is incomplete. The NC Department of Transportation (DOT) has failed to detail the
permanent impacts of the proposed bridge bents to be located in the North Toe River. DWQ cannot issue
a 401Water Quality Certification based on the current application due to DOT's failure to demonstrate
minimization of impacts in accordance with 15A NCAC 2H .0506(8).
If you have any questions regarding this matter, please contact Brian Wrenn at 919-733-5715.
