3. 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:
Mirror Lake is located in The Little Tennessee River Basin, Upper Cullasaja River Watershed, in Macon County, North
Carolina. The Cullasaja River is a tributary to the Little Tennessee River located in southeastern Macon County. The
watershed includes the Town of Highlands, which includes tourist and second -home communities. The Upper Cullasaja
watershed can be divided into four sub -watersheds of the four main tributaries of the Highlands Plateau: Big Creek, Mill
Creek, Monger Creek and the Cullasaja River which flow from their headwaters into Lake Sequoyah. Mirror Lake is
located upstream of Lake Sequoyah and is fed directly by the Cullasaja River and Mill Creek. Mill Creek runs through
downtown Highlands. A large amount of sediment has accumulated in Mirror Lake that has impacted the overall water
quality of the Lake.
The NCDEQ-DWR Integrated Report online map lists a portion of the Cullasaja River (upper 0.7 miles of MIRROR LAKE)
as Category 5 Impaired Waters [303(d) List] . From 0.6 miles downstream of US64 (head of Mirror Lake) to MIRROR
LAKE. Category 5 Assessments Approved by EPA August 10, 2012. From the 303(d) List;
Use: Aquatic Life
Reason for Rating: Fair Bioclassification
Parameter: Ecological/biological Integrity Benthos
Year: 1998
According to the NCDEQ-DWR NC Integrated Report, the receiving waters, below the Mirror Lake Dam are part of the
Cullasaja River and have a water quality classification of WS-III;Tr,CA with Potential Standards Violation for Turbidity,
from the backwaters of Lake Sequoyah to Dam at Lake Sequoyah. It is noted that "Potential Standards Violation for
Turbidity" exists prior to any Dredging or sediment removal work being performed at Mirror Lake.
3b. List the total estimated acreage of all existing wetlands on the property:
NA
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
The Surface Area of the Mirror Lake Impoundment is approximate 27 Acres.
The Original design Impoundment Volume was approximately 230 Acre -Feet. However, this storage is likely to be much
less at the present due to sediment accumulation.
3d. Explain the purpose of the proposed project:
This Project is for Dredging at Mirror Lake, Highlands, North Carolina. Large amounts of sediment have accumulated
throughout Mirror Lake to the point where the water quality has become impaired. The upper portion of Mirror Lake is
listed on the 303(d) list and having a Category 5 Impairment. Sediment removal is necessary to improve water quality
and restore use and function of the Lake.
Page 4 of 13
PCN Form —Version 1.3 December 10, 2008 Version

3e.
Describe the overall project in detail, including the type of equipment to be used:
DREDGING at MIRROR LAKE;
Sediment removal shall be performed at various locations within Mirror Lake as shown on attached Sheet C-5. The
dredging shall remove accumulated sediment within the limits of the Lake. Dredging shall not be performed below the
natural lake bottom elevation or beyond the original shoreline. The estimated volume of material to be removed is
approximately 73,000 cubic yards. The work may be performed in phases, where only a portion of the total estimated
quantity is removed. The lake level shall be lowered to the extent necessary to ensure that the sediment removal in
performed "in- the- dry", see attached Sheet C-1 thru C-6. Turbitidy curtains to be used around work area to prevent
turbidity. The drawdown fixtures (siphons and drain valve) shall have turbidity control devices as necessary to prevent
increased turbidity in the downstream waters.
METHOD of DREDGING;
Derdging and Sediment Removal shall be performed using one of the methods described in Section 11.0 on Sheet C-2 of
the attached plans. Only minimual incidental fall back during dredging. Upland disposal site with no return water and no
loss of wetlands, selected prior to beginning work and permitted under a separate PCN Application as necessaary.
TEMPORARY FILL - MUD MATS;
After the Lake level has been lowered, mud mats or timber mats may be used may be placed to create a stable work
platform. Mud mats and similar materials shall be considered as "temporary fill", and permitted as such. Temporary fills
must consist of materials, and be placed in a manner, that will not be eroded by expected high flows. Temporary fills
must be removed in their entirety and the affected areas returned to pre -construction elevations. The areas affected by
temporary fills must be revegetated and restored as appropriate. It is anticipated that the used of temporary fill will
require a NWP 3 or other similar permit(s).
WATER QUALITY;
To comply with Water Quality requirements, the work will be performed in the dry. This will be accomplished by opening
the drain valve at Mirror Lake Dam, or by installing siphons across or around the Dam as needed to control the turbidity in
the draw -down water being discharged downstream. All dewatering discharge shall have a turbidity of not more than 10
NTUs above background or as otherwise specified in DWQ's Turbidity Standards (15A NCAC 02B.0211(3.)(k.)). To
satisfy the required turbidity limit, the dewatering siphons shall discharge shall be filtered through a Bag Filtration Unit
with a 100 to 1 micron nominal rating. The turbidity level of all discharge shall be monitored with calibrated turbidity
meters and the filtration equipment shall be adjusted as necessary to insure compliance with Water Quality Standards.
The water around the dredging areas shall likewise be monitored with calibrated turbidity meters and the turbidity
curtains shall be adjusted as necessary to insure compliance with Water Quality Standards.
See attached Sheets C-1 through C-6 for a complete description of the work.

UPLANDS DREDGE MATERIAL DISSPOSAL AREA;
The uplands dredge material disposal area will be selected, proposed and permitted by the Contractor under a separate
PCN application prior to beginning work. This will be a seperate PCN Application Form . All dredged or excavated
materials must be deposited and retained in an area that has no waters of the United States. All Dredge materials shall
be disposed of in an uplands disposal area suitable for accepting material from 303(d) listed Category 5 waters. The
uplands disposal area shall be self-contained and shall have no discharge of leachate or stormwater runoff into surface
waters or into groundwater, without treatment and detention prusuant to all applicable Federal, State and Local
requiremetns. Return water may be subject to the requirements of a Nation Wide Permit (NWP 16) and other State and
Local permitting requirements. Should the total disturbed area of the uplands disposal site exceed 1-Acre, a
Sedimentation & Erosion Control Permit will be required from the NCDEQ-Division of Land Resources and/or the local
erosion control authority depending on the location of the disposal site. An impervously liined disposal area is
recommended.

THE DREDGING AT MIRROR
LAKE, HIGHLANDS, NC. THIS
DOCUMENT IS NOT
APPLICABLE FOR ANY OTHER
SITE.
GENERAL NOTES:
SUMER REMOWAL d MMOR LAKE
MIRROR LAKE IMPROULMLNT ASSOCIATION, INC,
1.0 SUMMARY. This Project is for Dredging at Mirror Lake, Highlands,
North Carolina. Limited sediment removal shall be performed at various
locations within Mirror Lake as shown on Sheet C-5. The dredging
shall remove accumulated sediment on the lake bottom. Dredging shall
not be performed below the original lake bottom elevation.
1.1 The estimated volume of material to be removed is approximately
73,000 cubic yards. The work may be performed in phases, where
only a portion of the total estimated quantity is removed.
2.0 As a result of the site evaluation, a number of observations have
been made and recommendations provided. It should be noted that
the observations and recommendations stated herein are based on
information available as of this writing. It is conceivable that
additional information may be forthcoming which bears on these
observations, recommendations and conclusions. The right is reserved,
therefore, to review and modify all observations, recommendations and
conclusions at any future point in time should, in fact, additional
information become available.
3.0 CODES. All work shall be in accordance with OSHA Safety and
Health Requirements, US Army Corps of Engineers 404 permit
requirements, NCDENR Division of Water Quality 401 permit
requirements, NC Sedimentation Pollution Control Act, North Carolina
State Building Code, Town of Highlands requirements, and all other
applicable codes, ordinances, and regulations.
4.0 PERMITS & NOTIFICATIONS. Prior to beginning work, the Owner
and/or Contractor shall obtain all required permits, rights—of—entry &
authorizations from adjacent property Owners, and Mirror Lake
Improvements Association Inc. The Owner and/or the contractor shall
notify the applicable regulatory agencies and any impacted downstream
property owners. Locate, flag and protect all underground and
underwater utilities and structures within the work area. Do not
perform work or locate any portion of the staging area within utility
easements, set—back, or R/W.
5.0 BACKGROUND. Mirror Lake is located in The Upper Cullasaja River
Watershed, in the Blue Ridge Mountains of Western North Carolina. The
Cullasaja River is a tributary to the Little Tennessee River located in
southeastern Macon County. The watershed includes the Town of
Highlands, which includes tourist and second—home communities. The
Upper Cullasaja watershed can be divided into four sub—watersheds of
the four main tributaries of the Highlands Plateau: Big Creek, Mill
Creek, Monger Creek and the Cullasaja River which flow from their
headwaters into Lake Sequoyah. Mirror Lake is located upstream of
Lake Sequoyah and is fed directly by the Cullasaja River and Mill Creek.
Mill Creek runs through downtown Highlands. A large amount of
sediment has accumulated in Mirror Lake.
6.0 WATER QUALITY CLASSIFICATIONS.
6.1 Upstream Waters — Cullasaja River. The Cullasaja River feeds
into Mirror Lake from the northwest. The upper (northwest) portion of
Mirror Lake is delineated as the Cullasaja River (Ravenel Lake) from 0.6
miles downstream of US 64 (head of Mirror lake) to Mirror Lake. This
portion of the river/lake has a NCDEQ Water Quality Classification of
WS—III;Tr. The waters are also listed as `impaired" on North Carolina's
Clean Water Act 303(d) list. AU Number: 2-21—(0.5)b. Overall IR
Cat.: 5.
6.2 Upstream Waters — Mill Creek. Mill Creek feeds into the Mirror
Lake from the southwest. Mill Creek, from source to Mirror Lake /
Cullasaja River, has a NCDEQ Water Quality Classification of WS—III; Tr
The waters are also listed as 'impaired" on North Carolina's Clean
Water Act 303(d) list. AU Number: 2-21-3. Overall IR Cat.: 5.
6.3 Downstream Receiving Waters — Cullosa,ia River. The waters
immediately downstream of Mirror Lake are identified as the Cullasaja
River (Lake Sequoyah), from backwaters of Lake Sequoyah to the dam
at Lake Sequoyah. This portion of the Cullasaja River has a NCDEQ
Water Quality Classification of WS—III;Tr,CA. These waters do not
appear to be listed as 'impaired" on the State's 303(d) list.
7.0 LAKE LOWERING. Lake lowering shall be performed by the
Contractor by opening the existing bottom drain valve at the Mirror
Lake Dam. The Contractor shall notify the Mirror Lake Improvement
Association Inc., NCDEQ—Division of Water Resources, USACE Wilmington
District Asheville Regulatory Field Office, and downstream property
Owners Association 14 days prior to the scheduled Lake Lowering. The
rate of draw—down shall not exceed one (1) vertical foot per day (1
Ft/Day). After dredging is complete the Lake shall be refilled to its
normal pool elevation while maintaining minimum flow to the
downstream waters at all times.
Sediment must be prevented from
reaching surface waters during the Lake
drawdown. The withdrawal fixture should
be placed as necessary to prevent the
release of sediment or the increase in
turbidity.
8.0 CONDITION FOR USE OF THIS PLAN.

9.0 TURBIDITY CONTROL DURING LAKE LOWERING. The discharge shall
be monitored for turbidity. The Turbidity Level of the discharge water
shall not exceed 10 NTUs above background at any time during
performance of this work pursuant to 15A NCAC 02B.0211 (3)(k).
Where this turbidity requirement can not be met by discharge from
the existing bottom drain valve, the Contractor shall furnish and
install temporary siphons to drawdown the Lake level. The siphon
inlet invert shall be located at mid depth of the water column to
prevent discharge of bottom sediment.
10.0 MINIMUM FLOW DISCHARGE. Minimum flow to the downstream
waters shall be maintained at all time during the performance of this
work.
11.0 METHOD OF DREDGING. The dredging shall be performed
"in—the—dry" by mechanical means after the Lake level has been
lowered. The Contractor shall furnish all necessary dredging and
earthwork equipment. This method requires an excavator to remove
the sediment in one continuous move or operation, in such a way
that the material is not double handled within the Lake bed or at a
location below the normal pool elevation.
11.1 DOZER PUSH METHOD. The Contractor shall used a bulldozer to
push a layer of accumulated sediment from the Lake bed to a
location beyond the normal pool elevation, delineated as the shoreline
at high water, in one continuous move or pass. If the equipment
operator stops this continuous motion within the Lake bed during a
pass or lift, then the operation and/or the responsible parties may
be in violation of federal law. Once the material is push out of the
Lake bed in one continuous operation, then the material may then be
temporarily stockpiled for loading onto dump trucks with watertight
bed liners for transport to the uplands disposal area. There shall be
no temporary stockpiles of sediment within the limits of the Lake
bed.
11.2 TRAVELING EXCAVATOR METHOD. The Contractor shall use a
trackhoe or other suitable bucket excavator to excavate the sediment
and transport each bucket load to a location beyond the normal pool
elevation, delineated as the shoreline at high water, in one continuous
move. Once the excavator scopes a bucket of sediment, the
excavator shall travel continuously non stop to the loading area
beyond the limits of the Lake bed before stopping. Once the
sediment is excavated and transported beyond the limits of the Lake
bed in one continuous operation, the material shall be directly loaded
into dump trucks with a watertight bed for transport to the offsite
disposal area. The excavator must perform a continuous move or
operation without stopping or doubling handling the material within
the limits of the Lake bed. If the equipment operator stops this
motion during a pass or lift, then the operation and/or the
responsible parties may be in violation of federal law. There shall be
no temporary stockpiles of sediment within the limits of the Lake
bed.
11.3 STATIONARY EXCAVATOR METHOD. Temporary timber mats may
be installed on the dry Lake bed and dump trucks may travel to the
excavation site where the trucks may be loaded directly by the
excavator in one continuous move or operation without stopping or
doubling handling the material within the limits of the Lake bed.
Where the Lake bed is to soft to support low ground pressure (LGP)
equipment, temporary timber mud mats may be placed to create a
stable work platform. The timber mats will be considered as a
emperor fill in the PCN Form and permitted accordingly. Once the
excavator scopes a bucket of sediment, the excavator shall load the
waiting dump truck with one continuous movement. Once the dump
truck is loaded, it shall travel continuously beyond the limits of the
Lake bed. There shall be no temporary stockpiles or doubling
handling of excavated material within the limits of the Lake bed. If
the equipment operator or truck driver stops this continuous motion
during excavation, loading and transport, then the operation and/or
the responsible parties may be in violation of federal law. Once the
material is excavated and loaded in one continuous nonstop operation,
the material shall be transported to the uplands disposal area.
11.3.1 TEMPORARY FILL — MUD MATS. Mud mats or timber mats
may be used may be placed to create a stable work platform.
Temporary fills must consist of materials, and be placed in a manner,
that will not be eroded by expected high flows. Temporary fills must
be removed in their entirety and the affected areas returned to
pre—construction elevations. The areas affected by temporary fills
must be revegetated and restored as appropriate.
11.4 WORK FROM SHORE METHOD. Near shore sediment removal may
be accomplished using shore based excavators. The dredging areas
will be limited to near shore locations that are within reach of a
"long—reach" track hoe. Excavated materials shall be placed in
adjacent dump trucks with watertight bed liners for transport to the
uplands disposal site. This method may be used when the Lake level
is at normal pool elevation, provided there is no spillage or fall—back
from the excavator during the sediment removal and a turbidity
curtain is provided around the work area.
12.0 INCIDENTAL FALLBACK. The Dredging methods described above
shall be performed in such a way as to minimize incidental fall back.
Incidental Fallback is could be defined as: "The incidental soil
movement from excavation, such as the soil that is disturbed when
dirt is shoveled, or back—spill that comes off a bucket and falls into
the same place from which it was removed.
'Incidental fallback' does not include soil
movements away from the original site.
Sidecasting.... and sloppy disposal practices
involving significant discharges into waters
have always been subject to section 404."

13.0 TESTING. Prior to beginning dredging and sediment removal,
samples from the accumulated sediment shall be collected and tested.
A minimum of six discrete samples collected to project depth and analyzed
separately for the following parameters:
7 Metals (arsenic, cadmium, copper, lead, mercury, selenium and zinc)
Polynuclear aromatic hydrocarbons (PNAs)
Polychlorinated biphenyls (PCBs)
Oil & Grease
Total Phosphorus
Nitrate + Nitrite
Ammonia—Nitrogen
Particle Size Analysis — Sieve and Hydrometer Analysis
Sampling and testing shall be in general accordance with USEPA document
entitled 'Methods for Collection, Storage and Manipulation of Sediments for
Chemical and Toxicological Analyses: Technical Manual" [USEPA, 2001].
12.1 The upper portion of Mirror Lake is listed on the 303(d) List as Impaired
waters.
14.0 MONITORING. Before work begins the downstream receiving
stream shall be evaluated. Depending on access, several monitoring
locations shall be established for determining the base—line condition of
the stream downstream waters. This may include initial cross sections
and photo documentation of these locations.
14.1 Downstream waters shall be monitoring periodically (minimum of
weekly) while work is being performed. All dredging and sediment
removal work shall be halted if an increase in downstream turbidity
exceeds 10 NTUs or if sediment is released. If sediment is released or
turbid waters persists, the DWQ will be notified within twenty four hours.
If sediment loss impacts the receiving stream then sediment removal
may be required under DWQ approval.
14.2 Monitor work being performed around the lake shore. The lake
level should be lowered at a rate not exceeding 1—Ft per day. Flow
to the receiving waters should not be removed or reduced to a level
detrimental to aquatic life. Owners and Contractors should expect
some increase in the lake level due to unusually severe storm events.
At the end of each work day, and other times when severe weather is
forecasted, all shore line work areas should be secured (by others)
against a rise in the water level.
14.3 Depending on the amount of time necessary to complete work,
sediment and erosion control measures may be necessary to stabilize
the exposed Lake bed.
14.4 When necessary, furnish and install sediment and/or turbidity
control measures at the discharge end of the bottom drain pipe, or at
the discharge end of the siphon.
15.0 PROTECTION OF LANDSCAPE. The Contractor shall exercise care
to preserve the natural landscape and waterways and shall conduct
E
the dredging operations so as to prevent any unnecessary destruction,
'o Co
scaring, or defacing of the natural surroundings in the vicinity of the
work. All unnecessary destruction, scarring, damage or defacing of

18.0 UPLANDS DISPOSAL AREA. The size and location of an suitable
uplands disposal area shall be proposed by the Contractor and shall be
permitted prior to beginning work. This will be a separate PCN
Application Form from the PCN covering the Mirror Lake Dredging
operation. All dredged or excavated materials must be deposited and
retained in an area that has no waters of the United States.
All Dredge materials shall be disposed of in on uplands disposal area
suitable for accepting material from 303(d) listed Category 5 waters.
The uplands disposal area shall be self—contained and shall have no
discharge of leachate or stormwater runoff into surface waters or into
groundwater, without treatment and detention pursuant to all applicable
Federal, State and Local requirements. Return water may be subject
to the requirements of a Nation Wide Permit (NWP 16) and other State
and Local permitting requirements. Should the total disturbed area of
the uplands disposal site exceed 1—Acre, a Sedimentation & Erosion
Control Permit will be required from the NCDEQ—Division of Land
Resources and/or the local erosion control authority depending on the
location of the disposal site. An imperviously lined disposal area is
recommended.
19.0 DOWNSTREAM WATERS. According to the NCDEQ—DWR NC
Integrated Report, the receiving waters, below the Mirror Lake Dam are
part of the Cullasojo River and have a water quality classification of
WS—III; Tr,CA with Potential Standards Violation for Turbidity, from the
backwaters of Lake Sequoyah to Dam at Lake Sequoyah. It is noted
that "Potential Standards Violation for Turbidity" exists prior to any
work being performed at Mirror Lake.
20.0 SHORE STAGING AREA. The shoreline disturbance, above the
normal pool elevation, shall be limited to a width of 10% for the Lake
frontage not to exceed 100' width of disturbance per 1000 linear feet
