Dear Mr. Mitchell:
Please find enclosed for your review the Pre -Construction Notification Form, pertinent
information, and fee associated with our project to replace the existing launching ramp
below our TVA Hiwassee Dam on the Apalachia Reservoir.
Currently, this ramp is the only public launching ramp on Apalachia Reservoir, and it is
in disrepair and has a poor launch angle. There is also no flow protection for this ramp.
This coupled with the poor launch angle causes difficulty loading and unloading
watercraft during high flow conditions when the nearby Hiwassee Dam is generating
power or spilling water. This project consists of removing the existing ramp, concrete
courtesy dock, and boulder by using an excavator and hydraulic hammer. The ramp will
be straightened to create a better launch angle downstream, and the associated boulder
will be removed and used as stabilization for the new ramp. Removing the boulder will
also eliminate an existing navigation hazard. Once the ramp is in place, additional
parking will be constructed near the maintenance building to accommodate more
boaters.
Thank you for your review. Please let me know if you have any questions or need
additional information.

Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The site is located on the TVA Hiwassee Dam Reservation. The ramp is the only existing public ramp to access the Apalachia Reservoir. The
reservoir is a popular place for fishing and boating.
3b.
List the total estimated acreage of all existing wetlands on the property: 0
3c.
List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 0
3d. Explain the purpose of the proposed project:
To improve launching of boats and other watercraft gaining access to the Apalachia reservoir. The existing ramp is in disrepair and the current configuration of
the ramp creates a difficult launch angle to the river when Hiwassee Dam is generating power. A large boulder at the end of the ramp creates a hazard for boats
when loading and unloading.
3e. Describe the overall project in detail, including the type of equipment to be used:
The existing ramp, fill, and boulder will be removed using a tracked excavator and hydraulic hammer. All debris will be removed for new ramp construction.
Excavator will place rock along the proposed ramp location to build a slope for the ramp. Reinforced concrete slab will be poured and cured on grade above the
water level then pushed into place. All concrete and asphalt paving will be done in the dry. Stabilization will be added to protect ramp from erosion.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The existing ramp is in disrepair and needs replacement. The current breakwater/courtesy dock is undermined and broken. Also a public safety
concern regarding the launch angle and large boulder during flow conditions. The angle is almost perpendicular to flow and current will push boats
into the boulder. This is the only public launch available on Apalachia Lake. Rather than developing a new access area with associated impacts, this
area will be renovated to improve conditions, safety and capacity.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Replacement ramp will be built in essentially the same footprint as the old to minimize disturbance. The curve of the existing ramp will be straightened
to improve the launch approach and angle relative to flow. During boulder removal a special drawdown of Apalachia Reservoir will be scheduled so
work can take place in the dry. Turbidity curtains will be installed and maintained along the lakeward side of the boulder and ramp areas during the
demolition & removal process.

TVA External Message. Please use caution when opening
CLASSIFICATION: UNCLASSIFIED
Jimmy Lemmond,
Thank you for speaking with me about utilizing Regional General Permit 198200030 (RGP 30), which authorizes
maintenance, repair, and construction activities in lakes and reservoirs owned, operated, and/or regulated by public
utility companies, TVA, and local governments in the state of North Carolina. The work you described includes removal
of the existing boat ramp below TVA's Hiwassee Dam on TVA's Apalchia Reservoir (an impoundment of the Hiwassee
River) and construction of a new boat ramp at this location (coordinates are 35.14690 N, 84.18006 W) in Cherokee
County, North Carolina. As described, the proposed project would involve impacts to waters of the U.S. for the
improvements of the new boat ramp beyond the original footprint of the existing boat ramp.
Effective January 1, 2017, we have modified this regional general permit for Apalchia Reservoir to require pre -
construction notification only for: 1) any excavation or the dredging activity greater than 1/10 (0.1) acre occurring in a
previously un -dredged area of open water; 2) construction of more than 10 boat slips; 3) construction of boat ramps
exceeding 20 feet in width; and 4) installation of fueling facilities on authorized structures. For all other activities as
described in the attached GP30, pre -construction notification to our office is no longer required. You may proceed with
your work as proposed provided all the conditions of the attached GP30 are met.
This statement does not preclude the need to obtain other applicable federal, state, or local authorizations for your
project. This modification does not affect the conditions or pre -construction notification requirements to receive the
required and corresponding Clean Water Act Section 401 Water Quality Certification #3898 from North Carolina Division
of Water Resources (DWR). Please contact Kevin Mitchell, at 828-296-4500, to determine the required pre -construction
notification/permit application submittal process for DWR.
If you have any questions regarding this information, you may contact me at 828-271-7980 x. 4232.

FROM: Andrea Leslie, Mountain Region Coordinator
Habitat Conservation
DATE: 9 February 2018
SUBJECT: Apalachia Lake BAA Launch Ramp Replacement
Hiwassee River, Cherokee County
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed
the permit application package for improvements at the Apalachia Lake boat access on the
Hiwassee River, which would involve excavation of 0.04 acre and fill of 0.08 acre. Our
comments are provided in accordance with certain provisions of the N.C. Environmental Policy
Act (G.S. 113A-1 through 113A-10; 1 NCAC 25) and the Fish and Wildlife Coordination Act
(48 Stat. 401, as amended; 16 U.S.C. 661 et seq.).
The project will involve the demolition of the current boat ramp, fill, and a large boulder with a
hydraulic hammer and tracked excavator. During project activities, the water level would be
lowered to the lower end of the ramp in order to perform much of the work in the dry. The
debris will be captured and used for new ramp construction. A reinforced concrete slab will be
poured and cured on grade above the water level then pushed into place. All concrete and asphalt
paving will be done in the dry.
This project should not affect trout and the activities do not need to be avoided during the trout
spawning moratorium.

Apalachia BAA Page 2 February 9, 2018
Hiwassee River, Cherokee County
We offer the following recommendations to minimize impacts to aquatic and terrestrial wildlife
resources:
1. Be vigilant with sediment and erosion control during site staging, construction, and cleanup.
Disturbed areas should be seeded, mulched and/or matted as soon as possible, preferably at
the end of each work day.
2. We recommend avoiding the removal of trees and shrubs at the site to the extent practicable
and supplementing native riparian vegetation in disturbed areas by planting native grasses,
forbs, shrubs, and trees at the site.
3. Erosion control matting used should be free of plastic or nylon mesh, as this type of mesh
frequently entangles wildlife and is slow to degrade, resulting in a hazard that may last for
years.
4. The area around the boulder and ramp that will be demolished should be surrounded by a
barrier that will lessen the loss of fine sediment and rock to surface waters from demolition
activities, and the rock/concrete debris should be collected from the river bed. Special care
should be taken to remove any rebar from the channel.
Thank you for the opportunity to review and comment on this project. If I can be of further
assistance, please contact me at [phone] or at andrea.leslie&ncwildlife.org.

Description of Proposed Action Continued from Page 1
The boat ramp at the Hiwassee tail water is in disrepair. The breakwater and courtesy dock are undermined and not working. The ramp is
curved and has a poor launch angle making loading and unloading difficult during generation flows. This is the only ramp on Apalacia
Reservoir making it necessary to improve. Project will remove existing ramp, remove a large boulder in the water by hammering, straighten
the ramp, add new breakwater, adde new courtesy pier, and add new parking. See attached site plan.

Part 2 Comments
A review of the TVA Natural Heritage Database on 11-3-2017 for potential impacts to state and
federally listed species resulted in these findings. There are twelve state listed (ten extant, one C -Fair
and one possibly historical) and three extant federally listed (Tan Riffleshell, Slabside Pearlymussel and
Cumberland Bean) aquatic species within a ten -mile and with no recorded occurrences within a one
mile radius of the proposed action. Due to the current water in the project site and the amount of demo
and construction proposed Aquatic Expert should comment prior to construction. One extant state
listed (Mountain Camellia) and and no federally listed plant species occur within a five -mile radius of the
proposed action. The Mountain Camelia has been found within one mile of the project area. Given the
project scope and location no impacts will occurr. No champion trees occur within a five -mile radius of
the proposed action. One extant state listed (Northern Long-eared Bat) and one extant federally listed
(Northern Long-eared Bat) terrestrial species are within a three-mile radius of the project location.

There are no caves within a three-mile radius of the proposed action. "Myotis grisescens (gray bat),
Myotis sodalis (Indiana bat), and Myotis septentrionalis (Northern Long-eared bat) are listed as a
federally endangered or threatened species for this area. All three species hibernates in caves. Gray
bat roosts in caves year-round and forages over streams and rivers. Indiana bat and northern long
eared bats migrate from winter caves to roost during the summer behind loose bark of dead or dying
trees or in tree cavities. This includes both individual bats and maternity colonies. Northern long-eared
bats are also known to roost in buildings, bridges, and culverts. Indiana bat and northern long-eared
bat forage within and around forests, as well as over bodies of water. Thirty-two occurrences of
Northern Long-eared bat and fifteen occurrences of Indiana Bat are recorded within a ten mile radius.
Four occurrences of Northern Long-eared Bat are recorded within a three mile radius with two
occurrences recorded within a one mile radius. Due to federally listed bats recorded within the
immediate proximety and that some trees will be removed, the Terrestrial Expert should comment on
potential impacts to bat species before beginning construction. BMPs would be used around all bodies
of water. Therefore, TVA has determined that there would be no effects to gray bat, Indiana bat, or
northern long-eared bat." There will be no impacts to sensitive species due to suitable habitat for the
species being absent on or immediately adjacent to the project location.

Terrestrial Animals T&E Species — Logan Barber for Jesse Troxler - A review of terrestrial animal
species in the TVA Natural Heritage database on November 8, 2017, resulted in records for two state -
listed species (blue -winged warbler and mountain chorus frog) and one federally listed species
(northern long-eared bat) within three miles of the project footprint. Two additional federally listed
species (bog turtle and Indiana bat), and one federally protected species (bald eagle) are known from
Cherokee County, North Carolina. Also, though no known records exist, the USFWS has determined
the federally listed gray bat has the potential to occur in Cherokee County, North Carolina. Effects to all
the species will discussed in the report (Table 1 Terrestrial Animal T&E Species).

The project would be located at Hiwassee River Mile 75.5L, on Apalachia Reservoir, in Cherokee
County, North Carolina. Based upon Table 10 in the 2008 Cherokee County, North Carolina, Flood
insurance Study, the 100 -year flood elevation at this location would be 1289.1 feet, referenced to NGVD
1929.
The boat launch, breakwater, courtesy pier and a portion of the parking area would be located within the
100 -year floodplain of the Hiwassee River. Consistent with EO 11988, these facilities would be
considered repetitive actions in the floodplain that should result in minor impacts. To minimize adverse
impacts, the courtesy dock would be securely anchored to avoid breaking free in major floods.
According to documentation provided by Mr. Lemmond, the new boat launch would occupy essentially
the same space as the current boat launch; therefore, there would be no fill within the Power Storage
Zone of Apalachia Reservoir or the 100 -year floodplain.
The TVA Flood Control Storage Loss Guideline does not apply because there is no flood storage on
Apalachia Reservoir.
Flood Risk has no objection to the proposed boat ramp reconstruction project, provided the following
condition is included in the CEC:
Condition:
• All floating facilities will be anchored securely to prevent them from floating free during major floods.
The stream reference should be listed as Hiwassee River Mile 75.5L.

A review of the TVA Natural Heritage database indicates two managed, four natural, and one heritage
area within a five -mile radius of the proposed actions. Five of these areas, Hiwassee Dam Reservation,
Raven Rock TVA Small Wild Area, Nanathala National Forest, Nantahal State Game Land, and NC
National Forests are recorded within one mile. This project scope is for refurbishment of an existing
public boat ramp and parking on Hiwassee Dam Reservation which is part of the recreation plan of TVA.
Raven Rock is a small wild area approximately 400 yards south of the project site along -side the
southern TVA boundary of dam reservation. Neither Raven Rock or this proposed project are in visual
sight of one another. National Forest bound TVA property along the west side of the dam reservation.
Due to the absence of a managed, heritage, or natural area on or immediately adjacent to the proposed

PREPARED BY: Chuck Howard (Aquatic Endangered Species Biologist- TVA)
James E. Emmert (JSG)
Part 2, Q1 - Potentially affect endangered, threatened, or special status species? YES
Commitments: NO
Comments:
The Tennessee Valley Authority (TVA) is proposing to reconstruct the boat ramp on the
Hiwassee River immediately downstream of Hiwassee Dam due to disrepair. The breakwater
and courtesy dock are undermined and not working. The ramp is curved and has a poor launch
angle making loading and unloading difficult during generation flows. This is the only ramp on
Appalachia Reservoir making it necessary to improve. The project will remove the existing
ramp, remove a large boulder in the water by hammering, straighten the ramp, add new
breakwater, add a new courtesy pier, and add new parking.
Review of the TVA Natural Heritage Database (6 December 2017 ) indicated records of 13 state
and/or federally listed aquatic animal species (1 crayfish, 4 fish, and 8 mussels) within 10 miles
of the project site (Aquatic Table 1). These records include three federally listed as endangered
mussels (Cumberland bean, slabside pearlymussel, and tan riffleshell; Aquatics Table 1).
However, none of the aquatic records are located within the reach of the river between
Hiwassee Dam and Apalachia Dam, where the proposed project is located.
The absence of records near the proposed project, in combination with the small areas of
potential impacts to the riverine environment (sedimentation from installation, rock removal,
disturbance/alteration of the existing bank and adjacent riverbed), TVA has determined that the
species listed in Aquatics Table 1 will not be affected. Therefore, no impacts to endangered,
threatened, or special status species will occur.
Part 2, Q7 - Potentially affect water flow, stream banks, or stream channels? YES
Commitments: NO
Comments:
The proposed project would alter bank soil and vegetation by means of heavy equipment
disturbance; however impacts to the bank above the normal flow elevation would be minor and
insignificant. Impacts to the riverbed and surrounding riverine environment would be extremely
localized, minor and insignificant. Implementation of BMP's along the bank above the normal
flow elevation would prevent erosion and pollutants from entering the stream.
Part 2, Q10 - Contribute to the Spread of Exotic or Invasive Species? NO
Commitments: NO
Comments:
Equipment and materials used for the project would be clean and free of debris that could
introduce exotic species and adversely affect the aquatic habitat. The project would not move
water or aquatic species from one location to another. Thus, the project would not contribute to
the spread of exotic or invasive aquatic species.

Part 2, Q17 - Potentially Affect Unique or Important Aquatic Habitats? YES
Commitments: NO
Comments:
Habitat for federally listed aquatic species occurs within the Hiwassee River within ten miles of
the project site; however, no records of these species occurs in the project reach (Apalachia
Reservoir). Therefore, no habitat that support federally listed species would be affected by the
project. Designated critical habitat for the Slabside pearlymussel (Pleuronaia dolabelloides) and
the Fluted kidneyshell (Ptychobranchus subtentum) occurs within 10 miles of the project site in
the Hiwassee River, but occurs 13 river miles downstream of the proposed project. Given the
nature of the project, and the proposed actions of this project, TVA has determined that the
project would not result in adverse modifications or destruction of designated critical habitats.

For Part 2.1 — Potentially affect endangered, threatened, or special status species? YES
Commitment: -None
Comments: -
Terrestrial Animals T&E Species — Logan Barber for Jesse Troxler - A review of terrestrial
animal species in the TVA Natural Heritage database on November 8, 2017, resulted in records
for two state -listed species (blue -winged warbler and mountain chorus frog) and one federally
listed species (northern long-eared bat) within three miles of the project footprint. Two
additional federally listed species (bog turtle and Indiana bat), and one federally protected
species (bald eagle) are known from Cherokee County, North Carolina. Also, though no known
records exist, the USFWS has determined the federally listed gray bat has the potential to occur
in Cherokee County, North Carolina. Effects to all the species will discussed in the report
(Table 1 Terrestrial Animal T&E Species).
Blue -winged warblers inhabit brushy hillsides, old pastures, as well as stream and woodland
edges. These birds forage in shrubs and trees normally low to the ground. Their diet, while not
well known, likely consists of ants, beetles, caterpillars, grasshoppers, and spiders. The closest
record of a blue -winged warbler is approximately 2.3 miles from the project footprint. No blue -
winged warblers were record during field reviews on January 10, 2018. Suitable habitat for the
species does exist in the project footprint. Direct effects to blue -winged warbler may occur to
some individuals that may be immobile during the time of project activities (i.e. juveniles or
eggs). This could be the case if project activities took place during breeding/nesting seasons.
However, with the small project footprint and the availability of similar suitable habitat in the
project vicinity, there would be no effect to blue -winged warbler populations.
Mountain chorus frogs occur on hilltops and forested slopes up to 3,500 feet in elevation. They
often breed in ditches, pools along streams, and can even use tire ruts along dirt or gravel
roads. The closest known record of mountain chorus frog is approximately 2.3 miles from the
project footprint. No mountain chorus frogs were seen during the field survey on January 10,
2018. Suitable habitat for mountain chorus frog does exist in the project footprint. Direct effects
to individuals are possible if present during construction activities. However, with the relatively
small size of the project footprint and the availability of similar suitable habitat in the project
vicinity, there would be no effect to mountain chorus frog populations.
Bald eagles are protected under the Bald and Golden Eagle Protection Act. This species is
associated with larger mature trees capable of supporting its massive nests. These are usually
found near larger waterways where fish, waterfowl, and other prey are abundant. The nearest
bald eagle record occurs approximately 7.4 miles from the project footprint. Foraging habitat
exists in the Hiwassee River. BMPs must be implemented to minimize any impacts to bald eagle
foraging habitat within the river. During a field review on January 10, 2018, no bald eagles and
no bald eagle nests were observed within 660 feet of the project footprint. With the
implementation of BMPs, bald eagle would not be affected by the proposed actions.
Bog Turtles inhabit slow, shallow, muck -bottomed rivulets of sphagnum bogs, calcareous fens,
marshy/sedge-tussock meadows, spring seeps, wet cow pastures, and shrub swamps; the
habitat usually contains an abundance of sedges or mossy cover. Beaver, deer, and cattle may
be instrumental in maintaining the essential open -canopy wetlands. The closest known record
of a bog turtle is approximately 18.1 miles in Towns County, Georgia. Suitable habitat for the

bog turtle does not exist within the project footprint and no bog turtles were seen during the field
survey on January 10, 2018. Bog turtle would not be affected by the proposed actions.
Gray bats are associated with caves year-round, migrating between different roosts in winter
and summer. Gray bats emerge at dusk to forage for insects along waterways. Though it is
within the known range of gray bat, no known records of gray bat exist within Cherokee County,
North Carolina. No caves are known from within 3 mile. During a field review on January 10,
2018, no new caves and no other winter roosting habitat was found within the project footprint.
Suitable gray bat foraging habitat does exist over the Tennessee River. BMPs must be
implemented to minimize impacts to gray bat foraging habitat. With the implementation of
BMPs, gray bat would not be affected by the proposed actions.
Indiana bats inhabit caves during winter and migrate to roost under exfoliating bark and within
cavities of trees (typically greater than or equal to 5 inches in diameter) during summer.
Foraging occurs along riparian areas and along the tops of trees, forested edges, and tree lines.
Some habitat requirements overlap between Indiana bat and northern long-eared bat, which
roost in caves or cave -like structures in winter, and utilize cave -like structures as well as live
and dead trees with exfoliating bark and crevices in the summer. Northern long-eared bats are
thought to forage primarily within forests below the canopy layer. The nearest known Indiana
bat record is approximately 4.7 miles from the project footprint. The nearest known record of
northern long-eared bats is approximately 0.2 miles from the project footprint. Foraging habitat
for Indiana bat and northern long-eared bat exists over the Hiwassee River, along forested
shorelines, and under the canopy of forests within the project footprint. BMPs must be
implemented to protect foraging habitats of Indiana bat and northern long-eared bat. During a
field review on January 10, 2018, no suitable summer roosting habitat was found within the
project footprint. With the use of BMPs, Indiana bat and northern long-eared bat would not be
affected by the proposed actions.

Description of the Undertaking
Short Description TVA -Facilities Management
Long Description The boat ramp at the Hiwassee tail water is in disrepair. The breakwater and courtesy
dock are undermined and not working. The ramp is curved and has a poor launch
angle making loading and unloading difficult during generation flows. This is the only
ramp on Apalacia Reservoir making it necessary to improve. Project will remove
existing ramp, remove a large boulder in the water by hammering, straighten the ramp,
add new breakwater, adde new courtesy pier, and add new parking. See attached site
plan.

Field Survey Recommendation (Appendix B, if survey required)
No Survey Required
Basis for Finding No Historic Properties Present or Affected
A review of the National Register of Historic Places indicates that no historic properties exist within the APE
or within its viewshed. Also, a review of the TVA land acquisition maps indicates no historic properties within
the APE. Given the lack of NRNP, and previously identified archaeological sites, TVA finds these factors
provide a reliable basis for concluding that the APE or its viewshed contains no historic properties.
During a survey of Hiwassee Reservoir (Riggs, 1996), no archaeological materials or intact deposits were
encountered. This area has been heavily disturbed by the construction of the dam and the associated
buildings. This lanform has little to no stratigraphic integrity left.
The undertaking will have no effect to historic properties.
