SAW-2024-02064 - CSXT Emergency Track Rebuild Post -Hurricane Helene, Blue Ridge Sub Milepost Z
142.5 to Z 165.0, Mitchell and Yancey Counties in NC.
This project is a linear transportation project as defined in United States Army Corps of Engineers (USACE)
regulations and the Interstate Commerce Commission Termination Act. CSX Transportation Inc. (CSXT)
proposes to rebuild the track infrastructure between Milepost (MP) Z 142.5 and MP Z 165.0 on the Blue Ridge
Subdivision in North Carolina, restoring needed rail service after the catastrophic damage from Hurricane
Helene flooding. The rebuild includes the track, roadbed, culverts, ditches, signals, and a bridge along this
22.5 miles of active CSXT ROW.
The project starts at the Tennessee and North Carolina state line at Latitude 36.072456' / Longitude
-82.417017°, near Poplar, Mitchell County, NC and ends at Latitude 36.017544' / Longitude 82.213283°, near
Red Hill, Mitchell County, NC.
General land use in the vicinity of the project varies widely from National Forest to small towns.
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the
past? *
Yes No Unknown
4f. List the total estimated acreage of all existing wetlands on the property:
0.29 acre
4g. List the total estimated linear feet of all existing streams on the property:
(intermittent and perennial)
30,000 In ft
4h. Explain the purpose of the proposed project: *
The Project will rebuild the CSXT rail infrastructure in order to restore the needed rail service damaged as a
result of the flooding after Hurricane Helene. The flooding resulted in a disruption of service on the Blue Ridge
Subdivision, particularly from MP Z 142.5 to Z 165.0 in NC, where rail infrastructure was damaged to such an
extent that trains cannot pass through this area. This rail line is a critical connection between Chicago and the
southeast coastal ports; therefore, the purpose of the Project cannot be met with the no build option.

Are any other NWP(s), regional general permit(s), or individual permits(s) used, or intended to be used, to
authorize any part of the proposed project or related activity? This includes other separate and distant
crossing for linear projects that require Department of the Army authorization but don't require pre -
construction notification.
No other NWPs, Regional General Permits, or Individual permits will be used or are intended to be used
within the State of NC to authorize the proposed project. The work in the gorge continues (MP Z 140.0 to Z
142.5) into Tennessee and is being permitted separately by the USACE Nashville District and TDEC.
We have not determined which (if any) culvert crossing streams will not require pre -construction notifications.
Additional storm damage repair work is occurring south of Red Hill (MP Z 165.0), but currently the permit
stops at MP Z 165.0.

For Impact S3 - Damaged culverts will be replaced 'in kind', therefore, no additional
impacts are proposed.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project: *
1. Use the Rail Pile Wall will minimize impacts below OHW by allowing the wall to replace
the slope further into the river in areas where the rail embankment would be more at risk
during a flood event or where the toe of the embankment slope would intrude into the
River beyond CSX ROW and/or where the roadbed was pre -storm.
2. Use temporary rail work bridge instead of culvert stream crossings.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction
techniques: *
1. Limit equipment in the streams to only where necessary for track and embankment
recovery, toe access reconstruction, and drilling rail pile wall.
2. In consultation with appropriate agencies, threatened and endangered species such as
the Appalachian Elk Toe Mussel historical populations will be identified and avoided as
much as possible.
3. Field determine OHW mark in the Nolichucky River.
4. Follow USFS stabilization BMPs, as applicable.
5. Use available materials within CSXT ROW and locally sources material to rebuild toe.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the
State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
Yes No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Mitigation requirements, if any, have not yet been determined.

track, roadbed, culverts, ditches, signals, and a bridge along this 22.5 miles of active CSXT right-of-way (ROW).
The project began in October 2024 and will be completed by summer 2025. The project is located in Mitchell and Yancey
Counties. The project starts at the Tennessee and North Carolina state line at Latitude 36.072456' / Longitude-82.4170171,
near Poplar, Mitchell County, NC and ends at Latitude 36.017544' / Longitude 82.213283°, near Red Hill, Mitchell County,
NC. The waterbodies within the project area include Nolichucky River, North Toe River, Lost Cove, Norris Branch, Flat
Branch, Sam's Branch, Shop Branch, Cooper Branch, Pigeonroost Creek, Brummett Creek, Warrick Branch, Raccoon Creek,
Big Rock Creek, Whitson Branch, Hollow Poplar Creek, and Cane River and their tributaries.
General land use in the vicinity of the project varies widely from National Forest to small towns.
The construction will require authorization pursuant to Section 404 of the Federal Clean Water Act, 33 U.S.C. § 1344 from
the United States Army Corps of Engineers (USACE) for the crossings of areas preliminarily identified as waters of the U.S.
(WOTUS) and subject to USACE confirmation. Initial notification of the emergency nature of the project was emailed to the
USACE and State -level regulatory agencies on September 30, 2024, specifically about the loss of the rail bridge near Poplar
(MP Z 147.9). The flooding started on September 26 due to rainfall from Hurricane Helene coming on shore and moving
inland. Additional emergency notifications were emailed to the USACE Asheville Field Office and North Carolina
Department of Environmental Quality (NC DEQ) on October 10, 2024, for the current project length (MP Z 142.5 to Z 166.0)
to include the loss of roadbed and track. No correspondence was received until November 1 when the USACE replied. A
Preconstruction Notification was submitted to the USACE Wilmington District on November 18 using the NC Department
of Environmental Quality (NCDEQ) eDocs website. This document is intended to provide additional supporting
documentation as part of the PCN submittal.
Clinchfield Consulting Group (Clinchfield) conducted an assessment of WOTUS (including wetlands) within the project area
during multiple site visits in October and November 2024. The report from the investigation will be included as Attachment
C. If required, a supplemental WOTUS report will be issued for the proposed borrow areas. Note: Due to safety issues,
delineation of the CSXT ROW from the Big Wall (MP Z 143.5) to the end of the railbed downstream of the Poplar Bridge (MP
Z 147.6) was not possible. The delineation was completed in this section using drone images.
CSXT will only make the necessary minimum impacts to WOTUS required to allow for the construction of an adequate
roadbed to rebuild the track and allow for access along the ROW. Anticipated Nationwide Permits that may apply for this
project include NWP 3 - Maintenance, NWP 13 - Bank Stabilization, NWP 14 - Linear Transportation Project, and NWP 45
- Repair of Uplands Damaged by Discrete Events. This notification requests authorization to continue construction of the
on -going emergency CSXT track rebuild. Sections 2.0 and 3.0 illustrate how this project meets the NWP General Conditions.
As a result of the extensive flooding, much of the track and associated roadbed was washed into the Nolichucky River (MP
Z 142.5 to Z 147.9). The remainder of the project footprint (MP Z 147.9 to Z 166.0) had more typical flood damage with
areas of lost track, erosion of rail embankment, and damage to culverts. Construction is currently underway to reconstruct

The Project will rebuild the CSXT rail infrastructure in order to restore the needed rail service damaged as a result of the
flooding after Hurricane Helene. The flooding resulted in a disruption of service on the Blue Ridge Subdivision, particularly
from MP Z 142.5 to Z 166.0 in North Carolina, where rail infrastructure was damaged to such an extent that trains cannot
pass through this area. Because of the geographic and environmental constraints, the alternatives are the Build or No Build
options with modifications to the build option to reduce impacts. This rail line is a critical connection between Chicago and
the southeast coastal ports; therefore, the purpose of the Project cannot be met with the no build option.
Section 1- Detailed Description of Proposed Impacts
1. Roadbed Rebuild in the Gorge. This includes the restoration of the roadbed or repair of uplands damaged by a
discrete event including culvert replacements, as needed. The railroad corridor through the gorge is parallel to
the Nolichucky River on the southern bank, within Yancey County. CSX plans to restore the roadbed, previously
considered upland areas, damaged during Hurricane Helene (using authorization under NWP45). The length of
roadbed directly adjacent to the Nolichucky River is approximately 23,700 linear feet. This excluded the length
behind the concrete wall and a section away from the river.
er 11;

a
Photo 1 - Toe Access and Rail Pile Wall (in TN)
Toe access is the first step in safely
getting equipment into the gorge to
remove rail debris, to create the rail pile
wall, and to start restoring the roadbed.
The goal is to keep these impacts within
the original footprint of the rail
embankment and within CSX ROW.
Through this section of track, CSXT ROW
is 100 feet wide or 50 feet from
centerline of the track on both sides.
Where the toe access must be outside of
the CSXT ROW, these impacts will be
temporary. Temporary toe access will be
removed, and the material will be added

to the rail embankment or re -used in another location. If the rail embankment needs to exceed the limits of CSXT
ROW, the intrusion will be coordinated with the regulatory agencies as part of the permitting process as well as
the property owner (most likely USFS) to acquire additional ROW or other agreements.
From the toe access, the rail pile wall will be used in specific locations to assist in rebuilding the rail embankment.
In areas that do not require the rail pile wall, the embankment will be built above the toe access.
Photo 2 - Rail Embankment being rebuilt (in TN)
Construction to rebuild the original embankment footprint may be authorized under NWP45 - Repair of Uplands
Damaged by Discrete Events. The permit authorized discharge of dredged or fill material into WOTUS for activities
associated with restoration of upland areas damaged by a discrete event including bank stabilization.
Construction outside of the original embankment footprint may be authorized under NWP14 - Linear
Transportation Project. In addition, to replacing previously serviceable culverts, NWP 14 authorizes temporary
structures, fills, and work and stream impacts necessary to construct the linear transportation project.
If necessary, CSXT proposes to complete the culvert replacements within the gorge under NWP 3 - Maintenance.
In addition, to replacing serviceable culverts, NWP 3 authorizes removal of accumulated sediment/debris within
200 feet of the structure and temporary structures, fills, and work necessary to conduct the maintenance activity.
Table 1 listed the streams within the gorge where it is anticipated that culverts may need maintenance, repair, or
restoration. The level of effort required has not yet been determined, due to access issues.

In addition to these activities,
A. The ballast curb wall or the 'big wall' near MP Z 143.5 to Z 143.9 will be raised by at least 2 feet to
accommodate the 2 feet raise of the low chord at both the Stateline Bridge (MP Z 142.5) and Poplar Bridge
(MP Z 147.9). This work will be completed above the OHW away from the Nolichucky River.
B. Modifications are proposed at the culvert at MP Z 145.8 at both the inlet and outlet ends to better support the
raised rail bed.

Plans have not been completed for these two additional areas.
2. Bridge Rebuild. The Project will replace the bridge over Str-1, Nolichucky River. The spans were lifted off the
foundations and washed off downstream during the flood event. Based on the amount of damage, the five existing
piers will be covered with a Fiber Reinforced Polymer Composite Pier Wrap, two new hammerhead piers with
Page 4

CSXT Emergency Rebuild Post -Hurricane Helene
MP Z 142.5 to MP Z 166.0, Mitchell and Yancey Counties, NC
cheekwalls and micropile foundations will be added, five new deck plate girder (DPG) spans will be used, and
three existing bridge spans will be reused. The 60% plan set for the rail bridge at Popular are in Attachment J.
The permanent below ordinary high-water mark (OHW) impacts will be the two new instream piers. Temporary
impacts include the forms required to create the two piers outside of the flow of the stream. To meet current
design standards and standard of care, the bridge was designed for the low chord to be two feet higher than the
previous structure. HDR is the designer of record for both the work and permanent bridges near MP Z 147.9.
Nolichucky River (Stream 1) is a Class C water. See Attachment F for research on wild and scenic rivers (to be
published).
CSX proposed to complete the bridge replacement within the gorge under NWP 3 - Maintenance. In addition, to
replacing serviceable bridges, NWP 3 authorizes temporary structures, fill, and work, necessary to conduct the
maintenance activity. Another option is the NWP 14 - Linear Transportation Project, since the bridge is an integral
part of the rail line rebuild. Table 2 lists the permanent bridge impacts.

Table 3 lists the temporary impacts required for the restoration of the rail bridge (MP Z 147.9).
A temporary stream crossing using two 8' diameter by 170' in length culverts was placed on bedrock with
temporary headwalls and topped with cellular concrete in Hollow Poplar Creek. The temporary crossing is
designed to overtop in high flow conditions with minimal damage to the surrounding work areas and for ease of
removal. The culverts, headwalls, and high flow channel were designed for a 5-year storm event. The crossing is
part of the temporary work area. Hollow Popular Creek (Stream 46) is a Class C water and is classified as a Trout
stream. The temporary below OHW impacts include the culverts, their bedding stone, headwall, and the concrete
on top.
The temporary work areas around the temporary stream crossing serve as a staging area for the permanent bridge
repairs and reconstruction; for assembling and use of the crane; and repair and/or salvage of the bridge spans.
Three bridge spans will be re -used and three will be salvaged. Due to erosion after the flooding event, material
was placed below OHW in a small portion of the temporary work area. We are still researching to determine the
volume of the fill temporarily placed.
The temporary crossing and temporary work areas will be removed after the permanent bridge is installed and
the bridge spans are removed from the Nolichucky River. The rail bridge will take an estimated six months to
build. Therefore, the temporary structures are expected to be in place for less than one year. The area will be
restored to pre -storm contours and stabilized using stabilization BMPs including the Forest Service specified seed
mix and cover after consultation with the USFS.
A temporary ford is being utilized as a low-water, bed -rock crossing in the Nolichucky River. The ford is temporary
and is expected to be actively used for less than 12 months. The Ford is located on privately owner property
(outside of USFS). CSXT has an agreement with the property owner for access. The banks along the River will be
restored to pre -disturbance contours and stabilized using the stabilization BMPs including the Forest Service
specified seed mix and/or cover or rip -rap after consultation with the USFS and the property owner. No material
was dredged and no fill was placed in creating the ford.
A temporary work bridge over the Nolichucky River will allow construction travel to cross the river without the
ford or a temporary culvert stream crossing. CSX felt based on the stream flows and recreational activities, a
culvert crossing would be impracticable at this location. The 90% plan set for the temporary work bridge is in
Attachment J. Temporary impacts include the four temporary piers and the timber cribbing to separate the new
piers from the stream while being created. The temporary work bridge is expected to be in place for less than one

will be restored to pre -disturbance contours and stabilized using stabilization BMPs including the Forest Service
specified seed mix and cover after consultation with the USFS and the property owner. No material was dredged
in preparation for the piers.

CSX is proposing to use an after -the -fact NWP3 permit to authorize the temporary impacts associated with
reconstructing the rail bridge near Poplar. If the temporary impacts are too far away from the rail bridge, an after -
the -fact NWP14 permit is another option.

The temporary stream crossing and work area near Poplar rail bridge were completed to access the bridge spans
in the water around November 7. The ford area was developed around November 6 to allow access to the opposite
bank without installing a temporary stream crossing. The foundation for the temporary work bridge was started
around November 6 to allow for access to the opposite bank without ford or culverts temporary crossing with the
in -stream forms to isolate the concrete from the Nolichucky River being removed around November 24. The work
bridge is expected to be completed by the end of the year.
3. Culvert Replacements South Poplar. As part of the design build process, the replacement culverts will be placed
under the roadbed, as needed. Existing culverts will be replaced, left in place, or slip lined as appropriate. Riprap

We anticipate the majority of the culvert replacements will be exempt from permitting requirements regulated by
the USACE and NC DEQ.
4. Roadbed Rebuild south of Poplar. In several areas south of Popular (MP Z 147.9 to MP Z 166), the flooding event
undercut the rail embankment adjacent to either the Nolichucky and/or the North Toe Rivers. These areas are
being surveyed to determine their length and the amount of stone needed to rebuild and/or protect the rail
embankment. We anticipated that the majority of the roadbed repairs will be conducted under NWP 45. Table 5
will list these locations and length of impacts.

S. Recovery of rail, ties, and other OTM. During Hurricane Helene, rail, track panels, rail ties, and other railroad
materials (OTM) were washed off the rail embankment and into areas along the rivers and upland areas
downstream. CSX is in the process of recovering this property. It is a dangerous operation. In some cases, the
material can be reclaimed without working in the OHW, while in the majority of cases, toe access is required to
recover the rail material and the harder recovery will require equipment in the rivers.
Section 2 - General Description of Construction Methods. The following construction method will be used when
working around the streams found within the project area to avoid adverse stream impacts.
The equipment being used in the stream or along the stream bank is a mixture of specialized equipment and
construction equipment used in stream restoration work. The equipment is being inspected daily.
1. Rail Material Recovery: CSXT and their contractors will be working below OHW in the Nolichucky River and
North Toe River when necessary to recover rail, ties, and other on -track materials (OTM). The rail material may
be anywhere within the rivers above or below OHW. Where possible the material will be removed with
equipment located on the bank or toe access (above OHW, if practicable). Where it is not possible, equipment
may have to work in the stream or walk equipment across the stream to safely remove the material.
When equipment must enter the stream as part of recovery, in -stream material may have to be shifted to create
a path or a level work area. During this process, other material in the river will not be hammered, removed for

re -use, and bedrock will not be impacted. After the rail material is removed, the area will be restored, as
practicable, as the equipment is moved back out of the stream. During this operation, the equipment will only be
in the stream when actively working to recover rail material.
2. Rebuilding Track in the Gorge: CSXT track was significantly damaged in the gorge from the flooding event
associated with Hurricane Helene. A rendering of how the roadbed will be reconstructed is included in
Attachment I for both the section of track where a rail pile wall is required and the remaining sections of track.
A photo log for MP Z 141 to Z 145 (Attachment B) documents rebuilding the roadbed in Tennessee and initial
work in North Carolina.
Photo 4 - Example of locations where rail embankment was 'damaged' in NC
a. Toe Access: Toe access is the first step in gaining access in the NC section of the gorge and allowing CSX to
remove track, ties, and OTM from the river and to drill the toe pile walls. It also serves as the starting point to
rebuild the rail embankment. Figure 1 below and in Attachment A shows the area of toe access.
_ - -- s CSXT and their contractors will build toe access starting below
.� ordinary high water (OHW) in CSX ROW along the bank of the
r
Yam, s Nolichucky River. To extent practicable, toe access will be built
* ' to match the pre-existing rail embankment to allow equipment
access where the railroad roadbed was inaccessible. The toe
"'�''' " - access is necessary for equipment to safely enter the gorge
where the rail bed was damaged due to the flooding associated
with Hurricane Helene. The toe access will be placed on the rail
side embankment along the edge of the inland rail side slope.
Photo 5 - Toe Access
Stone with a driving surface will be used to form the toe access
along CSX ROW where the rail embankment was prior to the
flood. This is how CSX will start restoring the upland areas
damaged during Hurricane Helene (NWP45) with minor
dredging of mainly the previous rail embankment stone within
the CSX ROW and/or no more than 10 feet beyond the CSX

ROW. Below OHW material used will focus on angular rock assumed to be part of the original rail embankment
and will not impact bedrock in the Nolichucky River.
The amount of material required to build the 12-15 feet wide toe access approximately two feet above the water
surface will vary based on the post -flood site conditions.
b. Rail Pile Wall: CSXT and their contractors will need to work below OHW in the Nolichucky River on the rail side
of the river. The work includes clearing overburden, moving material, and creating work platforms to allow for
drilling of the proposed rail pile wall and continuing to build the rail embankment. The term Toe Pile Wall or
Rail Pile Wall are equivalent for this project. Figure 1 and Attachment A shows the proposed location of rail pile
walls. Attachment F includes a rendering of the construction of the Rail Pile Wall and the cross-section for the
rail embankment using the rail pile wall. The utilization of the rail pile wall in critical locations along the project
area will minimize impacts to the Nolichucky River and minimize impacts to the track from future flooding.
Because access through the gorge on the NC side is still unsafe in locations, the exact locations of the rail pile
walls have not been established. CSX or their agent will provide this information to the USACE as their locations
are determined.
The concrete wall near MP Z 143.5 (Big Wall) provides a similar purpose as the rail pile wall. This permanent
structure/retaining wall provides a stable toe for the roadbed. The main concrete structure was not damaged
during the flood event, but extensions on top of the wall were damaged. The area does not have toe access, but it
separates the rail embankment from the Nolichucky River, allowing the material that washed behind the wall
can be rebuilt outside of the OHW footprint.
c. Roadbed: The roadbed will be reconstructed using stone and other onsite and borrow material. roadbed. In
locations, the pre -flood rail embankment can be delineated based on the angular roadbed material on the rail
side of the river. A mixture of large and medium stones will be placed on top of the toe access and behind the
rail pile wall progressing the rail embankment above OHW. Very large stones will be placed along the toe of the
slope for additional stabilization. Where possible these stones will be shifted from nearby locations along the
rail embankment. Once the base reaches the appropriate height, sub -ballast and then ballast will be placed,
followed by the ties, rail and other OTM. Near MP Z 144, a section of the roadbed was not damaged as
significantly as others, most likely because it is not directly adjacent to the Nolichucky River.
In addition to the roadbed required for the rail to be reconstructed, temporary bump outs will be included in the
rail embankment. This will allow locations during construction where vehicles can turn around or pull off.
Where possible, the temporary bump outs will be located within CSX ROW. If not within CSX ROW, they will be
removed and the material re -used. If within CSX ROW, but outside of the original roadbed footprint, their
temporary or permanent status will be coordinated with the regulatory agencies.
d. Culverts: Where the roadbed and its associated culverts were damaged or completely washed out, CSXT and
their contractor' will replace culverts. The culverts in streams are listed in Tables 1 for the gorge area. CSX
brought standard sized culverts as part of their emergency response that were used to replace damaged or
missing culverts. The replacement culverts were installed in the dry, by placing them when no or minimum flow
was occurring or diverting flow around the work area. Culverts will be installed as per NCDEQ requirements for
embeddedness.
e. Material Being Used in the Gorge: CSXT plans to use available materials within CSX ROW and other locally
sourced material to rebuild the rail embankment and toe access. CSX is proposing using material from multiple
sources focusing on materials within CSX ROW near the work area for the toe access and initial embankment.
CSXT estimated rebuilding the roadbed within the gorge will require an estimated 1 million cubic yards of
material.
1) The first source is material from the inland side of CSX ROW. This material within CSX ROW was in upland
areas before the embankment was washed away during the flood event. The initial overburden will be
removed and used in construction of the toe access. After the rail pile wall is installed, the contractor will
chip & run the inland bank to remove large rocks to start construction of the embankment.

2) The second source is material from the river side of CSX ROW. The stones along the river side of the CSX
ROW that are mainly original rail embankment (angular stones) are the only areas that CSX plans to borrow
below OHW. From the rivers side, the material will be from below or above OHW within CSX ROW and
material below OHW no more than 10 feet beyond CSX ROW. This material will be reshaped into toe access
or for use mainly along the toe of the reconstructed embankment.
3) The remaining material, which CSXT is proposing to use, is a mixture of original rail embankment and river
stone that was deposited in upland areas (above OHW) after the flood event. A portion of this stone will be
from flood deposits in TN and some will be from flood deposits in NC. CSX is in the process of surveying the
areas with deposits of material in NC to verify whether there is enough material in the identified areas to
make borrowing operations efficient and to verify ownership of the property. Once an area is confirmed as
usable, CSX will work with the property owner to gain permission to use the borrow material and will work
with both the owner and the regulatory agencies to develop a restoration plan for the upland area (above
OHW) that will remain after the borrow operation are complete.
Borrow areas: Borrow areas have been identified (Figure 5) where flood waters washed material (rock) that
might be able to be savaged and re -used to reconstruct the rail infrastructure. The borrow areas will only be
used if they are within CSX ROW or in locations where CSX has permission from the property owner to remove
the stone. Once approved, these areas will be delineated to identify WOTUS (Attachment C) and to determine
the ordinary high water (OHW) mark (Attachment E). Rock and other usable materials will be recovered from
these locations outside of WOTUS and above OHW.
Restoration plans for the borrow areas will be developed in conjunction with the property owners. These plans
can be provided to the USACE, as needed, once property owner negotiations have been completed and plans
have been developed.
Materials from borrow areas along the river will be transported by off -road trucks along the partially restored
railbed embankment to continue the process of rebuilding the rail embankment. The alternative to haul the
needed material using on -road dump trucks was discounted because of the limited access within the gorge, CSX
felt they could not get quarried stone into the area fast enough. There were safety concerns about adding more
on -road dump truck traffic to the existing overused roadway network. In addition, the closest route from area
quarries to the work areas in North Carolina involves crossing through mountain passes using narrow, curvy,
and steep roads. As of November 13, 2024, three on -road dump truck drivers have lost control of their vehicles;
two were killed. There was also some discussion about potential impacts to the Appalachian elktoe if material
from outside of the river were used. CSXT has requested USFWS identify any known or historic population
locations, so these areas can be marked, and extra care can be taken in these areas when recovering rail, ties, or
other on -track -materials from the river.
The sub -ballast and ballast will be brought from approved CSXT quarries and placed above OHW.
3. Bridge: CSXT and their contractors will reconstruct the Poplar Bridge. The low chord on the rail bridge near Poplar
(MP Z 147.9) over Nolichucky River will be raised by two feet, which will result in the roadbed in the gorge being
raised two feet.
The wet concrete will be segregated from any flowing water when the two supplement piers are formed. Concrete
trucks were not allowed to clean equipment within the project area. The reconstruction work will be completed in
the dry.
4. Rebuilding Track south of the Rail Bridge at Poplar: In several areas south of Popular (MP Z 147.9 to MP Z 166), were
damaged due to flooding. These areas are being surveyed to amount of impact and potential solutions. Work in the
area will range from none due to no damage to completely rebuilding the rail embankment. Work below OHW in this
section beyond the rail material recovery will include culvert replacements, bank stabilization, and roadbed
reconstruction. CSX or their agent will provide this information to the USACE as their locations are determined. Stone
from local quarries will be used for the rail work outside of the gorge.

MP Z 142.5 to MP Z 166.0, Mitchell and Yancey Counties, NC
a. Culverts: Where the roadbed and its associated culverts were damaged or completely washed out, CSXT and
their contractor' will replace culverts. The culverts in streams south of the gorge are listed in Table 4. CSX
brought standard sized culverts as part of their emergency response that were used to replace damaged or
missing culverts. The replacement culverts were installed in the dry, by placing them when no or minimum flow
was occurring or diverting flow around the work area. Culverts will be installed as per NCDEQ requirements for
embeddedness.
b. Bank Stabilization: Where the river side of a rail embankment was eroded during the flood event, quarried stone
will be used to rebuild or provide additional stabilization. The locations, lengths, and volume of material to be
placed below OHW will be added to Table 5. The material used for bank stabilization will be of a size to reduce
its potential to be eroded during a flood or other high water event.
5. Blasting. At this time, CSXT does not plan on using blasting to create material to rebuild the rail embankment. If
blasting is proposed, CSX or their agent will provide this information to the USACE as their locations are determined. A
small charge was used to improve access on the north abutment of the rail bridge at MP Z 147.9 on USFS property
above OHW within 100 feet of the Nolichucky River.
6. Best Management Practices (BMPs). Throughout the construction process, BMPs will be used. The list of agreed upon
BMPs is in Attachment H.
7. Ordinary High Water Elevation. To determine if impacts are below or above Ordinary High Water (OHW), CSXT
Subconsultant EnviroScience completed a survey along the North Toe and Nolichucky Rivers within the project area to
field verify if they could use physical characteristic to determine the OHW mark. The evaluation of river substrate
composition found a few locations that appeared to have the required components for determination of OHWM after
the major flooding event. The field indicators were limited due to the impacts from Hurricane Helene floodwaters,
which severely scoured river substrates and the riparian buffer and caused significant realignment of substrates and
historical erosional and depositional areas. The report indicated the OHWM was 24 inches above the existing water
surface elevation in the Nolichucky River (both inside and outside of the gorge) in North Carolina and 36 inches above
the existing water surface elevation in the North Toe River. Attachment G.
Section 2.0 Direct and Indirect Adverse Environmental Effects
There will be direct environmental impacts to streams due to the roadbed reconstruction, bridge replacement, culvert
replacements, and bank stabilization. The fill is necessary to accommodate the roadbed required for the proposed track
per CSXT standards. Existing/pre-flood damaged drainage patterns do not appear to be altered. Impacts to protected
species (Appalachian Elktoe) are not anticipated based on damaged from the storm event and the current scope of the
proposed project. Refer to Section 4, General Condition 18.
Recreational Use. Because of the rail material in the Nolichucky River, CSXT requested that the Nolichucky River be
closed to the public until the rail material is removed. The USFS made the decision to not issue commercial licenses to
guide/rafting companies working until the area is deemed safe, but they cannot close the Nolichucky River to private
citizens. CSXT posted signs to advise the public of the unsafe conditions in the Nolichucky River. This is a temporary
impact to the recreational public using the gorge. Though the area can be used year-round. According to USFS the area
is most utilized by the recreational public in the Summer. CSXT plans to remove the majority of the debris as long as
they can safely access the river using their planned toe access within approximately six to eight months. Figure 3 in
Attachment A shows the location of the adjacent USFS owned property.

Photo 6 - Signage Warning of Unsafe Conditions.
Section 3.0 Avoidance and Minimization
CSXT will minimize the impacts to WOTUS by placing the minimum amount of fill necessary to restore the track and
its drainage structures.
The use of the Rail Pile Wall will minimize impacts below ordinary high water by allowing the wall to replace the slope
further into the river in areas where the rail embankment would be more at risk during a flood event or where the toe
of the embankment slope would intrude into the River beyond CSX ROW and/or where the roadbed was located prior
to the flooding event.

Potential impacts to water quality will be reduced by implementing best management practices in accordance with the
requirements of the Federal Clean Water Act, 33 U.S.C. § 1251 et seq. A Stormwater Pollution Prevention Plan (SWPPP)
will be created along with the submission of the Notice of Intent for coverage under the North Carolina NPDES
Construction General Permit, NCG250000, will be competed once adequate data has been collected. The BMPs in
Attachment— form the majority of the erosion and sediment control measures.
Following minimization and avoidance in accordance with 40 C.F.R. Part 230 and 33 C.F.R. Part 325, minimal impacts
to WOTUS are necessary to meet the project's purpose and need of restoring the rail line after the damage caused by

Hurricane Helene. Avoidance of WOTUS features was not achievable while maintaining the necessary specifications
needed to meet CSXT operation and safety standards.
Section 4.0 General Conditions
1. Navigation - The Nolichucky River within North Carolina is not designated as a navigable water, per conversations
with the USACE Asheville field office. The proposed project will rebuild the railbed where it was previously located
prior to the catastrophic floods following Hurricane Helene. No adverse impact to navigation within the Nolichucky
River will occur as a result of the project.
2. Aquatic Life Movements - The proposed project includes several culvert and bridge crossings of tributaries to the
Nolichucky River. The permanent crossings will be constructed to maintain low flows to sustain the movement of
aquatic species between the Nolichucky River, North Toe River, and their tributaries.
3. Spawning Areas - The project would not affect important spawning areas; however, Best Management Practices
(BMPs) will be implemented to control erosion and sedimentation that could affect offsite aquatic habitat.
4. Migratory Bird Breeding Areas - The project would not affect areas that could potentially serve as breeding areas for
migratory birds.
5. Shellfish Beds - The project site does not contain shellfish beds; therefore, this condition is not applicable.
6. Suitable Material - The proposed activity would not involve the use of unsuitable material. Native/original material
will be used where possible. Imported fill will be free of toxic pollutants.
7. Water Supply Intakes - The project will not affect water supply intakes.
8. Adverse Effects from Impoundments - The project site does not propose impoundments; therefore, this condition is
not applicable.
9. Management of Water Flows - The proposed activity would not adversely affect water flows in the vicinity of the
project.
10. Fills Within 100-Year Floodplains - The proposed project is located directly adjacent to a Special Flood Hazard Area
(Zone AE) of the Nolichucky River and North Toe River; as well as crossing over the Special Flood Hazard Area (Zone
AE) of Big Rock Creek (FEMA Panels 3710081400K, 3710081500K, 3710081600K, 3710082400K, 3710082500K,
3710083300K, 3710083400K, 3710084300K, and 3710084400K, all effective 6/2/2009). In the Nolichucky River the
Zone AE designation stops in NC before entering the Gorge at the Rail Bridge (MP Z 147.9) and resumes downstream
of the rail bridge at MP Z 140.0. The gorge is Zone A. Because the rail embankment is being restored back as much as
possible within the pre -flood footprint, its restoration should not impact the Zone A floodplain. The low chord on the
rail bridge near Poplar (MP Z 147.9) is being raised two feet.
11. Eguinment - The proposed project will require equipment typical of site grading, drilling, and construction projects
along or in a stream. Specialized equipment is being used to assist with drilling the rail pipe wall.
12. Soil Erosion and Sediment Controls - Best Management Practices will be utilized following CSXT standards
supplemented as needed by the North Carolina Erosion and Sediment Control Planning and Design Manual and USFS
guidance, as appropriate.
13. Removal of Temporary Fills - Temporary fill will occur in multiple locations throughout this segment of the project.
They include toe access beyond the proposed railroad embankment, areas where the access is temporarily widened to
allow for pull-out or turn around points, and the temporary impacts to reconstruct the rail bridge and its temporary
work bridge. All temporary fills will be removed in their entirety and original contours re-established and stabilized
using stabilization BMPs including the Forest Service specified seed mix and cover after consultation with the USFS.
14. Proper Maintenance -The proposed project will be properly maintained to protect public safety.
15. Single and Complete Project -The proposed project is likely to include several separate crossings of WOTUS, each of
which will be considered a single and complete project per 33 CFR 330.2(i).

MP Z 142.5 to MP Z 166.0, Mitchell and Yancey Counties, NC
16. Wild and Scenic Rivers - The Nolichucky River has not been designated as a wild and scenic river or a wild and scenic
study river. The Nolichucky River from Poplar NC downstream to the rail bridge at Unaka Springs TN is listed on the
Nationwide Rivers Inventory (NRI) as one of the free -flowing river segments in the US that are believed to possess one
or more 'outstandingly remarkable' natural or cultural values judged to be at least regionally significate and as such is
a potential candidate for inclusion in the National Wild and Scenic River System. In 1993, the Nolichucky River was
listed with Outstandingly Remarkable natural or cultural Values (ORV) for scenic, recreational, and geologic.z This
preconstruction notification has been prepared to comply with the requirement to submit a PCN for work in the
vicinity of a wild and scenic river.
17. Tribal Rights - The project as proposed is not expected to affect Tribal fishing, hunting, or water rights.
18. Endangered Species - Impacts to endangered species are not anticipated by the project, see Section 2.0. Clinchfield
reviewed the U.S. Fish & Wildlife (USFWS) on-line database for "Natural Resources of Concern." The IPaC Report
(Attachment D) identified five (5) federally listed species that should be considered in an effect's analysis, plus one
(1) candidate species. (Table 3).

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. 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.
Insects
Monarch Butterfly

In the spring and summer, often found in open fields and meadows with
Danaus plexippus
milkweed.
Flowering Plants
Virginia Spiraea
LT
Virginia spiraea is found along scoured banks of high gradient streams
Spiraea virginiana
or on meander scrolls, point bars, natural levees, and braided features of
lower stream reaches. This species prefers soils that are sandy, silty, or
clay and elevation range is 1000- 2400 feet. If the roots are exposed,
they will give rise to upright stems.
C - Candidate for Listing, Substantial information exists in USFWS files on biological vulnerability to support proposals to list
as endangered or threatened.
LT - Species for which a final rule has been published in the Federal Register to list the species as threatened. Species is legally
protected by the Endangered Species Act.
LE - Species for which a final rule has been published in the Federal Register to list the species as endangered. Species is legally

EXPN- Experimental population, non -essential. A population that has been established within its historical range undersection
106f) of the ESA to aid recovery of the species. The Service has determined a non -essential population is not necessary for the
continued existence of the species.
The IPaC Report indicated that there is designated critical habitat for the Indiana bat; however, it does not overlap
with the Project Review Area. The IPaC Report indicated that there is designated critical habitat for the Appalachian
elktoe, which does overlap with the Project Review Area. The remaining species do not have critical habitat established.
During the field review, Clinchfield biologists evaluated the site for habitat for the federally listed species. Based on
general observations, the Project Review Area does contain suitable habitat for the Appalachian elktoe, Virginia
spiraea, Indiana bat, and northern long-eared bat.
In consultation with appropriate agencies, threatened and endangered species such as the Appalachian Elk Toe
Mussel historical populations will be identified, documented, and avoided as much as possible. If impacts are
determined from construction an after -the -fact mitigation plan will be developed in consultation with appropriate
agencies. If tree clearing is required, it will be minimal and occur in accordance with the time of year restriction.
The following species were reviewed in more detail:
a. LE -Gray Bat: No caves were identified during the survey; therefore, no impacts to the gray bat are anticipated.
The closest known cave3 with suitable habitat is located approximately 4 miles northwest of the Project
Review Area.
b. LE - Indiana Bat and Northern Long-eared Bat: The Project Review Area includes trees with loose and
exfoliating bark that could provide summer roosting habitat for the Indiana Bat or Northern Long-eared Bat.
Per the time of year (TOY) restriction from the USFWS Indiana Bat and Northern Long-eared Bat Survey
guidelines, trees can be cleared between October 1 and March 31 without further consultation with USFWS.
(Attachment D). Due to trees damaged as a result of the flood event, CSXT does not anticipate significant tree
cutting. CSXT will attempt to identify and cut any potential bat habitat trees on or before March 31.
c. LE - Appalachian Elktoe: The Project Review Area contains suitable habitat for the Appalachian elktoe,
primarily in the Nolichucky River. The other tributary streams located in the Project Review Area are high
gradient streams that generally would not provide suitable habitat for this species. The proposed activity is
not intended to disturb areas within the Nolichucky River that historically provided suitable habitat for the
Appalachian elktoe. The rebuild work is limited to the shoreline and adjacent riverbank that were eroded
away during the Hurricane Helene flooding event. Due to the close proximity to the Nolichucky River, indirect
impacts due to sedimentation could affect the Appalachian elktoe. Direct impacts to the mussel species may
occur when CSXT is in the river recovering rail material. CSXT has requested USFWS identify any known or
historic population locations, so these areas can be marked, and extra care can be taken in these areas when
recovering rail, ties, or other on -track -materials from the river.
d. C - Monarch Butterfly: Some areas within the Project Review Area contain suitable habitat for the monarch
butterfly. However, the monarch is a candidate species and not yet listed or proposed for listing. There are
generally no Section 7 requirements for candidate species. Coordination with USFWS is not anticipated, due
to the relatively minor impacts to potential habitat areas.
e. LT -Virginia Spiraea: The Project Review Area may contain suitable habitat for the Virginia spiraea; however
significant disturbances have occurred due to the flooding associated with Hurricane Helene within the
proposed project area. Much of the native vegetation was removed within the project area; therefore, impacts
to the Virginia spiraea are not anticipated.
19. Historic Properties - There are no National Register of Historic Places listed properties or sites within the project
corridor or within 0.5-miles of the project corridor. The original Clinchfield rail line was built in 1909. Though the area

* These rivers are listed as having Outstandingly Remarkable natural or cultural Values (ORV), see Attachment F.
Class C are waters protected for uses such as aquatic life propagation, survival and maintenance of biological integrity
(including fishing and fish), wildlife, secondary contact recreation, and agriculture. Secondary contact recreation
means wading, boating, other uses not involving human body contact with water, and activities involving human body
contact with water where such activities take place on an infrequent, unorganized, or incidental basis.
Class B are waters protected for all Class C uses in addition to primary contact recreation. Primary contact recreation
means swimming, diving, water skiing, and similar uses involving human body contact with water where such activities
take place in an organized manner or on a frequent basis.
Class Tr is a supplemental classification intended to protect freshwaters that have conditions that sustain and allow
for natural trout propagation and survival and for year-round maintenance of stocked trout. This classification is not
the same as the NC Wildlife Resources Commission's Designated Public Mountain Trout Waters designation.
The receiving waters downstream for the construction site should not exceed 50 NTUs; for trout waters its 10 NTUs.
22. Mitigation - The project is being designed to minimize permanent and temporary impacts to WOTUS to the greatest
practicable extent. However, due to the extreme nature of the damage to the rail infrastructure, unavoidable impacts
Page 20

Supporting Information - NWP PCN
CSXT Emergency Rebuild Post -Hurricane Helene
MP Z 142.5 to MP Z 166.0, Mitchell and Yancey Counties, NC
to WOTUS are anticipated above the mitigation threshold. Therefore, CSXT will re-evaluate mitigation requirements
that meet the applicable provisions of 33 CFR part 332 once impacts to aquatic resources have been quantified.
23. Safety of Impoundment Structures - The project site does not propose impoundments; therefore, this condition is not
applicable.
24. Water Quality - This preconstruction notification has been submitted to the NC DEQ for Section 401 Water Quality
Certification, as well as the USACE Wilmington District.
25. Coastal Zone Management - The proposed project is not located in the Coastal Zone Management area.
26. Regional and Case -By -Case Conditions - This proposed project will comply with state and regional conditions, as

IPaC resource list
This report is an automatically generated list of species and other resources such as critical habitat
(collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's (USFWS)jurisdiction
that are known or expected to be on or near the project area referenced below. The list may also
include trust resources that occur outside of the project area, but that could potentially be directly or
indirectly affected by activities in the project area. However, determining the likelihood and extent of
effects a project may have on trust resources typically requires gathering additional site -specific (e.g.,
vegetation/species surveys) and project -specific (e.g., magnitude and timing of proposed activities)
information.
Below is a summary of the project information you provided and contact information for the USFWS
office(s) with jurisdiction in the defined project area. Please read the introduction to each section that
follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional
information applicable to the trust resources addressed in that section. - \ Ir N

Endangered species
This resource list is for informational purposes only and does not constitute an analysis of project
level impacts.
The primary information used to generate this list is the known or expected range of each species.
Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside of the
species range if the species could be indirectly affected by activities in that area (e.g., placing a dam
upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the
species by reducing or eliminating water flow downstream). Because species can move, and site
conditions can change, the species on this list are not guaranteed to be found on or near the project
area. To fully determine any potential effects to species, additional site -specific and project -specific
information is often required.
Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary
information whether any species which is listed or proposed to be listed may be present in the area of
such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal
agency. A letter from the local office and a species list which fulfills this requirement can only be
obtained by requesting an official species list from either the Regulatory Review section in IPaC (see
directions below) or from the local field office directly. % %rok v
For project evaluations that require USFWS concurrence/review, please return to the IPaC website and
request an official species list by doing the following:
1. Draw the project location and click CONTINUE.
2. Click DEFINE PROJECT.
3. Log in (if directed to do so).
4. Provide a name and description for your project.
5. Click REQUEST SPECIES LIST.
Listed speciesl and their critical habitats are managed by the Ecological Services Program of the U.S.
Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic and Atmospheric
Administration (NOAA Fisheries).
Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown on this list.
Please contact NOAA Fisheries for species under their jurisdiction.
1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also shows
species that are candidates, or proposed, for listing. See the listing status page for more information.
IPaC only shows species that are regulated by USFWS (see FAQ).
2. NOAA Fisheries, also known as the National Marine Fisheries Service (NMFS), is an office of the
National Oceanic and Atmospheric Administration within the Department of Commerce.
The following species are potentially affected by activities in this location:

Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely to be
present in your project area. This information can be used to tailor and schedule your project activities
to avoid or minimize impacts to birds. Please make sure you read "Supplemental Information on
Migratory Birds and Eagles", specifically the FAQ section titled "Proper Interpretation and Use of Your
Migratory Bird Report" before using or attempting to interpret this report.
Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project
overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar
indicates a higher probability of species presence. The survey effort (see below) can be used to establish
a level of confidence in the presence score. One can have higher confidence in the presence score if the
corresponding survey effort is also high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in the week
where the species was detected divided by the total number of survey events for that week. For
example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them,
the probability of presence of the Spotted Towhee in week 12 is 0.25.

11/15/24, 12:24 PM IPaC: Explore Location resources
2. To properly present the pattern of presence across the year, the relative probability of presence is
calculated. This is the probability of presence divided by the maximum probability of presence
across all weeks. For example, imagine the probability of presence in week 20 for the Spotted
Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week
of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25
= 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of
presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season( )
Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds across its
entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.
Survey Effort (1)
Vertical black lines superimposed on probability of presence bars indicate the number of surveys
performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is
expressed as a range, for example, 33 to 64 surveys.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data (—)
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are based on all
years of available data, since data in these areas is currently much more sparse.

What does IPaC use to generate the potential presence of bald and golden eagles in my specified location?
The potential for eagle presence is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is
based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list
of those birds reported as occurring in the 1Okm grid cell(s) which your project intersects, and that have been identified
as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may
apply). To see a list of all birds potentially present in your project area, please visit the Rapid Avian Information Locator

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds.
Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any
location year round. Implementation of these measures is particularly important when birds are most likely to occur in
the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding
their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be
breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be 4�1\1
advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on
your project site.
What does IPaC use to generate the list of migratory birds that potentially occur in my specified location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that
may warrant special attention in your project location.
The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN).
The AKN data is based on a growing collection of survey., banding, and citizen science datasets and is queried and
filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and
that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle
Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not
representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project
area, please visit the Rapid Avian Information Locator (RAIL) Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in
my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian
Knowledge Network (AKN). This data is derived from a growing collection of survey., banding, and citizen science
datasets.
Probability of presence data is continuously being updated as new and better information becomes available. To learn
more about how the probability of presence graphs are produced and how to interpret them, go the Probability of
Presence Summary and then click on the "Tell me about these graphs" link.
How do I know if a bird is breeding, wintering or migrating in my area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-
round), you may query your location using the RAIL Tool and look at the range maps provided for birds in your area at
the bottom of the profiles provided for each bird in your results. If a bird on your migratory bird species list has a
breeding season associated with it, if that bird does occur in your project area, there may be nests present at some
point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your
project area.

What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range
anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental
USA; and
3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the
Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in offshore areas from certain types
of development or activities (e.g. offshore energy development or longline fishing).
Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid
and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more
information on conservation measures you can implement to help avoid and minimize migratory bird impacts and
requirements for eagles, please see the FAQs for these topics.

For additional details about the relative occurrence and abundance of both individual bird species and groups of bird
species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also
offers data and information about other taxa besides birds that may be helpful to you in your project review.
Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS
Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic
Outer Continental Shelf project webpage.
Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including
migration. Models relying on survey data may not include this information. For additional information on marine bird
tracking data, see the Diving Bird Study_ and the nanotag studies or contact Caleb Spiegel or Pam Loring.

Proper Interpretation and Use of Your Migratory Bird Report
The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern.
To learn more about how your list is generated, and see options for identifying what other birds may be in your project
area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified
location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that
overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey
effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high
survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as
more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of
certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of
concern have the potential to be in your project area, when they might be there, and if they might be breeding (which
means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in
knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities,
should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation
measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust
resources page.

Wetlands in the National Wetlands Inventory (NWI)
Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of
the Clean Water Act, or other State/Federal statutes.
For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers
District.
Please note that the NWI data being shown may be out of date. We are currently working to update our
NWI data set. We recommend you verify these results with a site visit to determine the actual extent of
wetlands on site.
This location overlaps the following wetlands:
FRESHWATER FORESTED/SHRUB WETLAND
PF01A
RIVERINE
R3UB1 H
R5UBH
R3UBH
A full description for each wetland code can be found at the National Wetlands Inventory website
NOTE: This initial screening does not replace an on -site delineation to determine whether wetlands
occur. Additional information on the NWI data is provided below.
Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on
the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery.
Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use
of imagery; thus, detailed on -the -ground inspection of any particular site may result in revision of the wetland
boundaries or classification established through image analysis.
The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the
amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata
should be consulted to determine the date of the source imagery used and any mapping problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be
occasional differences in polygon boundaries or classifications between the information depicted on the map and the
actual conditions on site.

11/15/24, 12:24 PM
Data exclusions
IPaC: Explore Location resources
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery
as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic
vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some
deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These
habitats, because of their depth, go undetected by aerial imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a
different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory,
to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical
scope of the regulatory programs of government agencies. Persons intending to engage in activities involving
modifications within or adjacent to wetland areas should seek the advice of appropriate Federal, state, or local agencies
concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities.

Replacement
Good afternoon,
Based on this morning's conversation regarding the CSX bridge replacement on the TN/NC border, it appears that
work may be planned that may not be considered exempt from 404 permitting and could emergency review and
authorization from the Wilmington District. Ms. Brooke Davis and Mr. Mitchell Anderson from my Asheville Office
are cc'd and are the appropriate POCs action in this area and stand ready to work with CSX to further discuss any
permitting that may be required.
Please do not hesitate to reach out to them with questions. We will work with CSX to expedite any required
actions.

Good Afternoon: The Nashville District has stated that the Nolichucky is a Section 10 Water and
is requiring a Section 10 Permit. Mr. Ehorn is requesting we fill out the proposed natural disaster mitigation
and flood recovery permit. He stated that it is not in effect yet - but we could use as a guide to proceed
forward with the Blue Ridge Sub repair project. I wanted to reach out to you and ask if you will be requiring
the same for the NC section of track. Thanks

FINAL FactSheet_WNCFlood Response_20CT2024 (1).pdf, PostHelene_PermittingQuickGuide.pdf,
Good Afternoon Scott,
For informational purposes, the reach of the Nolichucky in North Carolina is not a designated Section 10 water,
and the referenced natural disaster mitigation and flood recovery permit is a Regional General Permit for
Tennessee only. As far as the activities that are exempt under Section 404(f) of the Clean Water Act are
concerned, they remain the same in both Tennessee and North Carolina (i.e. debris removal, replacing damaged
structures in the same character, size and location, etc.). With regard to bridge replacement projects or the like, if
a causeway, instream diversion, etc. would need to be installed within the water, these types of activities would
constitute new fill (even if it temporary) into waters of the U.S., and would require a permit. We are under
emergency permitting procedures, and are providing two options so as to not slow the repair process, as follows:
1. Emergency Permitting process: Submit a request with the information indicated on the attached
QuickGuide and we will determine if the project is an emergency. If the project is determined to qualify as
an emergency, we will verify the permit within 48 hours.
2. After -the -Fact Permitting process: Once the work is complete, you may submit and after -the -fact Pre -
Construction Notification to this office (and the Division of Water Resources for the 401 WQC, if the work
does not fit under the general certification).
If you know of numerous areas along the corridor that would require new fill within waters of the U.S., it may be
easier for all involved if you provided those in one submittal and we can have a blanket letter for all -just a
thought. As I stated previously, I have attached our reference guides for emergency permitting procedures to this
email. Please do not hesitate to contact me if you have questions or concerns.
Sincerely,
Brooke

Amanda,
As we discussed during the site visit on Thursday,
project to keep the communication open.
we are providing you with information about the
For SAW-2024-02064, the CSXT Emergency Track Rebuild Post -Hurricane Helene, Blue Ridge Sub
Milepost Z 142.5 to Z 165.0, Poplar, Mitchell County, NC
The applicant is: Matthew L. Adkins, CSX Transportation Inc., He is Snr Manager Environmental
Rededication, 1590 Marietta Blvd NW, Atlanta, GA 30318.
The authorized Agent is: Clinchfield Consulting Group (Robin L Hagerty) at 5310 Maryland Way, Ste.
390, Brentwood, TN 37027.
If we keep the impacted length in the same application, it starts at the Tennessee and North Carolina state
line at Latitude 36.072456' / Longitude-82.417017°, near Poplar, Mitchell County, NC and ends at
Latitude 36.017544' / Longitude 82.213283°, near Red Hill, Mitchell County, NC
The attached link includes is a series of maps illustrating CSXT ROW along the Blue Ridge Subdivision
from the North Carolina State Line with Tennessee at MP Z 142.5 to the end of the requested emergency
authorization at MP Z 165.0. On top of this map, we have started to indicate where streams cross CSXT
ROW. We are working to refine this map to include what work is completed and being completed in each
segment and what NWPs are anticipated at potenitally jusditional locations.
CSXT ROW-STRs MP 142 to 165 2.pdf
From MP Z 142.5 to MP Z 147.9 (Gorge)
CSXT and their contractors are working below OHW in the Nolichucky River on the rail side of the river.
The work includes clearing overburden, moving material, and creating work platforms to allow for
drilling of the proposed toe pile wall and continuing to build the rail embankment. The equipment being
used is a mixture of specialized equipment and construction equipment used in stream restoration work.
The equipment is being inspected daily.
The utilization of the toe pile wall in select locations along the project area will minimize impacts to the
Nolichucky River and minimize impacts to the track from future flooding. CSXT is using available
materials within railroad ROW and locally sourced material to rebuild the rail embankment and toe
access. Material within CSXT ROW being recovered along the Nolichucky River is above the estimated
ordinary high water (estimated at 18" above surface water on 11/13/24 near MP Z 147.9). The
Nolichucky River is a Class B stream.
The attached link includes photos of the site in areas for the rail pile wall, the typical view of the rail pile
wall section for the rail bed, and rail pile wall locations.

Rail Pile Walls.pdf
We discussed using NWP 14, NWP3, and NWP45 with their emergency components for this segment of
the project including the bridges discussed below.
This segment of the Nolichucky River (from Poplar NC downstream to the rail bridge at Unaka Springs
TN) is listed on the Nationwide Rivers Inventory (NRI) as one of the free -flowing river segments in the
US that are believed to possess one or more `outstandingly remarkable' natural or cultural values judged
to be at least regionally significate and as such is a potential candidate for inclusion in the National Wild
and Scenic River System. In 1993, the Nolichucky River was listed with Outstandingly Remarkable
natural or cultural Values (ORV) for scenic, recreational, and geologic.[1]
From MP Z 147.9 Crossing Nolichucky River
CSXT and their contractors are working below OHW in the Nolichucky River at the bridge crossing near
Poplar, NC. The work includes clearing overburden, moving material, and creating work platforms to
allow for crane assembly and the proposed bridge work. The equipment being used is a mixture of
specialized equipment and construction equipment used in stream restoration work. The equipment is
being inspected daily.
A temporary stream crossing using two 8' diameter culverts was placed on bedrock with temporary
headwalls and topped with cellular concrete in Hollow Poplar Creek. The temporary crossing is designed
to overtop in high flow conditions with minimal damage to the surrounding work areas and for ease of
removal. The crossing is part of the temporary work area. Hollow Popular Creek is a Class C water and
is classified as a Trout stream
The tempoary work areas around the temporary stream crossing serve as a staging area for the permanent
bridge repairs and reconstruction; for assembling and use of the crane; and repair and/or salvage of the
bridge spans. Three bridge spans will be re -used and three will be salvaged.
The tempoary crossing and temporary work areas will be removed after the permanent bridge is installed
and the bridge spans are removed from the Nolichucky River. The area will be restored to pre -storm
contours and stabilized using USFS BMPs included Forest Service specified seed mix and cover.
A temporary ford is being utilized to cross the Nolichucky River on bedrock until the work bridge is
installed.
The attached link includes photos of these areas, the work bridge plan set, and sheets from the permanent
bridge plan set.
Bridge at Popular.pdf
Where found:
CSXT and their contractors are working below OHW in the Nolichucky River and North Toe River, when
necessary to recover rail, ties, and other on -track material (OTM).
The segment of the North Toe River (from US 19E bridge north of Ingalls to the confluence with Cane
and Notlichucky Rivers) was listed in 1982 with Outstandingly Remarkable natural or cultural Values
(ORV) for scenic, recreational, geologic, fish, and wildlife on the Nationwide Rivers Inventory (NRI) and
as such is a potential candidate for inclusion in the National Wild and Scenic River System. [ 1 ]

RE: Nolichucky and North Toe River Ordinary High Water Mark (OHWM)
Survey.
Dear Mr. Adkins,
On November 14 and 22, 2024, EnviroScience, Inc. performed a survey for the Ordinary
High Water Mark (OHWM) of the Nolichucky River and North Toe River. The survey was
completed over 4.7 miles from the first CSX railroad bridge upstream of Erwin, TN to
approximately two miles upstream of the NC/TN state line, 0.4 miles of the river at Poplar,
NC, and on the Toe River just upstream of the confluence with Cane River. The total
survey area was approximately 5.2 miles.
The OHWM survey followed the US Army Corps of Engineers' National Ordinary High
Water Mark Field Delineation Manual for Rivers and Streams (Interim Version),
November2022. However, field indicators were limited due to the impacts from Hurricane
Helene floodwaters, which severely scoured river substrates and the riparian buffer and
caused significant realignment of substrates and historical erosional and depositional
areas. These impacts also limited the locations where OHWM could be measured.
The OHWM on the Nolichucky was measured to be 24 inches above the river level on the
day of the site visit (November 14), at which time the USGS gage height at Embreeville,
TN was approximately 1.5 feet for reference. The OHWM on the Toe River was measured
to be 36 inches above the river level on November 22, 2024. There are no active stream
gauges on the North Toe River and the measurement was taken at normal to low flow
conditions. Determination of the OHWM was based on vegetation density and the
demarcation of well -established and/or woody vegetation. Other indicators used were the
presence of undercut banks and bank angle. See table below and the attached photo log
and maps for additional details and location information.

Best Management Practices (BMPs)

CSXT Emergency Rebuild Post -Hurricane Helene
MP Z 142.5 to MP Z 165.0, Mitchell and Yancey Counties, NC
Best Management Practices (BMPs)
1. CSXT WILL LIMIT EQUIPMENT IN THE STREAMS TO ONLY WHERE NECESSARY FOR TRACK AND
EMBANKMENT RECOVERY WITH WORK BELOW OHW TO INSTALL TOE ACCESS AND RAIL PILE
WALLS (WHICH MAY INCLUDE WORK WITHIN THE STREAM).
2. EQUIPMENT USED BELOW OHW WILL BE CONSISTENT WITH STREAM RESTORATION
PRACTICES AND INSPECTED DAILY.
3. WITHIN THE GORGE, CSX IS USING AVAILABLE MATERIAL WITHIN THE RAILROAD ROW AND
LOCALLY SOURCES MATERIALS THAT INCLUDE MATERIAL THAT MAY HAVE BEEN PART OF THE
ORIGINAL RAIL EMBANKMENT TO REBUILD TO RAIL EMBANKMENT.
4. THE WORK BRIDGE INSTALLATION IS NECESSARY TO MINIMIZE CONSTRUCTION IMPACTS TO
THE NOLICHUCKY RIVER.
5. RAIL PILE WALL IS BEING CONSTRUCTED WHERE NEEDED TO MINIMIZE EMBANKMENT
IMPACTS TO THE NOLICHUCKY RIVER AND TO HARDEN THE NEW TOE TO MINIMIZE FUTURE
IMPACTS DUE TO FLOODING.
6. IN CONSULTATION WITH APPROPRIATE AGENCIES, HISTORICAL POPULATIONS OF
THREATENED AND ENDANGERED SPECIES SUCH AS THE APPALACHIAN ELK TOE MUSSEL
WILL BE IDENTIFIED, DOCUMENTED, AND AVOIDED AS MUCH AS POSSIBLE.

MARCH 31.
8. THE OHW MARK WILL BE NOTED IN THE FIELD ONCE AGREED UPON BY THE REGULATORY
AGENCIES ALONG THE NORTH TOE AND NOLICHUCKY RIVERS WITHIN THE CSX FOOTPRINT.
9. CSXT WILL NOTIFY THE REGULATORY AGENCIES OF THE LOCATION WHERE EQUIPMENT IS IN
THE RIVER AS RECOVERY AND REMOVAL OF RAIL MATERIALS OCCURS BELOW OHW.
10. IF ANY PREVIOUSLY UNKNOWN HISTORICAL REMAINS OR ARTIFACTS ARE DISCOVERED
DURING CONSTRUCTION ACTIVITIES, CSXT WILL NOTIFY THE USACE OF WHAT WAS FOUND
AND TO MAXIMUM EXTEND PRACTICABLE, STOP ACTIVITIES THAT WOULD ADVERSELY
AFFECT THE REMAINS OR ARTIFACTS.
11. CSXT WILL NOTIFY LOCAL OFFICIALS IF REMAINS ARE FOUND FROM THE MOST RECENT
FLOOD EVENT. PERSONAL PROPERTY WITH AN ASSUME VALUE WILL ALSO BE TURNED OVER
TO LOCAL OFFICIALS.
12. TEMPORARY FILL AND CULVERTS WILL BE REMOVED AND IMPACTED AREA RESTORED
WITHIN 60 CALENDAR DAYS OF NO LONGER BEING REQUIRED.
13. CSXT ENGAGED A PRIVATE WHITEWATER RAPIDS EXPERT TO PROVIDE RECONNAISSANCE
AND CONSULTATION.
14. CSXT REQUESTED THAT THE NOLICHUCKY RIVER BE CLOSED TO THE PUBLIC WITHIN THE
GORGE UNTIL THE MAJORITY OF THE RAIL MATERIAL IS REMOVED DUE TO ITS HAZARDOUS
CONDITIONS.
15. CSXT POSTED SIGNS TO ADVISE THE PUBLIC OF THE UNSAFE CONDITIONS IN THE
NOLICHUCKY RIVER.
