2. EXECUTIVE SUMMARY

c.o:me=con,muoaorne, r.�.
Area 1 is an 18-acre (ac), coal combustion residuals (CCR) structural fill with a soil cap situated
near the northeastern Asheville Regional Airport (ARA) property boundary. The structural fill was
constructed pursuant to a contract between Charah, Inc. (Charah) and the property owner, ARA
Authority, to expand airport operations. The Area 1 footprint formerly consisted of a topographic
valley prior to construction and contained a historical stream channel that flowed northward within
the property. The historical stream channel traverses a residential area situated on the northern
property boundary adjacent to Area 1 before it discharges into the French Broad River. Area 1 was
constructed by filling the existing topographic valley with CCR purchased by Charah from the
Duke Energy Progress, LLC (Duke Energy) Asheville Steam Electric Plant. The construction of
the Area 1 structural fill was previously authorized in 2008 by the U.S. Army Corps of Engineers
(USACE) through the issuance of a Clean Water Act (CWA) Section 404 permit (SAW-2007-
03766-311) and by the North Carolina Depailiuent of Environmental Quality (NCDEQ) through
the issuance of a CWA Section 401 permit (DWQ #20071841).
The original soil cap was designed with the anticipation that impervious surface would be
constructed over the soil cap thereby largely eliminating infiltration of rain and surface water. The
impervious surface was not constructed and in August 2019, NCDEQ requested that a remedial
permanent cap system be designed to "abate the infiltration of groundwater and/or precipitation
into Area 1" and "to abate or control ... seepage water". As such, The ARA Authority (property
owner and applicant) and Duke Energy (engineering and construction of the permanent cap) are
proposing to install a remedial nonpermeable permanent cap (permanent cap) over the structural
fill at Area 1 of the ARA (project). The need of the permanent cap is to institute necessary site
controls for stabilization of the structural fill that comply with NCDEQ Solid Waste requirements
for containment of CCR at Area 1 (reduce infiltration of water into existing soil cap for CCR
structural fill) and meet required regulatory stormwater runoff capture requirements.
The project (approved by NCDEQ Solid Waste Section in 2020) is comprised of two components:
1) nonpermeable permanent cap layer system and 2) two sediment basins will be converted to
stormwater basins (dry detention) post -construction. The permanent cap will be installed entirely
within uplands and is designed to shed surface water and to drain water infiltrated within the cap
to minimize potential ponding atop the geomembrane layer. The new cap system has also been
designed to allow the ARA Authority to use Area 1 for expansion of airport operations as originally
planned under the prior issued permits.
Two stormwater basins will be constructed on the north side of Area 1 to capture and detain
stormwater to achieve stormwater runoff capture requirements. The stormwater basins were
designed following the NCDEQ Stormwater Design Manual and the NCDEQ Erosion and
Sediment Control Planning and Design Manual. During construction and post -construction the
stormwater basins will also be used as a sediment basin. The stormwater basins are also designed

as dry detention to release stormwater within 48 hours pursuant to Federal Aviation Administration
(FAA) regulations as not to attract nuisance wildlife.
An alternatives analysis was performed for the project to identify the least environmentally
damaging practicable alternative (LEDPA). To fulfill the project purpose and need and achieve
the LEDPA, the preferred alternative was selected as the applicant's preferred project for further
environmental analysis since it achieved the greatest avoidance and minimization of impacts to
aquatic resources. Construction of the preferred alternative's stormwater basins will result in
approximately 0.56-acre of cumulative wetland impacts and the installation of the outlet control
structure will result in 12 LF of stream impacts. The project has avoided and minimized impacts
to the maximum extent practicable (avoided 605 LF of stream and 0.96 ac of wetlands). Sixty-
three percent (63%) of wetlands and 98% of perennial streams of on -site wetlands/waters were
avoided by the project.
Protected species or their respective habitats were not observed within, or immediately adjacent to
the project area and therefore, the proposed project would not affect federally listed species.
Further, based on the preliminary cultural resources survey performed by RSWA, North Carolina
State Historic Preservation Office (SHPO) stated that no further archaeological investigations are
warranted for the project and that the proposed project will not affect any historic properties,
cultural or archaeological resources.
To satisfy the compensatory mitigation requirements for the project the ARA Authority will submit
a mitigation purchase request form to the DMS ILF program to secure wetland and stream
compensatory mitigation for the project.

3. INTRODUCTION
Geosyntec°
consultants
c.o:me=c.n,muncsof r.�.
The ARA Authority and Duke Energy are proposing to add additional site controls for stabilization
of the structural fill prior to further development of Area 1 for airport use. The additional site
controls required to comply with NCDEQ are (1) install a nonpermeable permanent cap layer
system over the structural fill at Area 1 and (2) develop two sediment basins that will be converted
to stormwater basins (dry detention) post -construction to meet required regulatory stormwater
runoff capture requirements for Area 1 cap system. The permanent cap will be installed entirely
within uplands and is designed to shed surface water and to drain water infiltrated within the cap
to minimize potential ponding atop the geomembrane layer. The new cap system has also been
designed to allow the ARA Authority to use Area 1 for expansion of airport operations as originally
planned under the prior issued permits.
The construction of the Area 1 structural fill was previously authorized in 2008 by the USACE
through the issuance of a CWA Section 404 permit (SAW-2007-03766-311) and by the NCDEQ
through the issuance of a CWA Section 401 permit (DWQ #20071841). Duke Energy is
responsible for design and construction of the permanent cap. The ARA Authority, as owner of
the property, is the applicant for this project.
As such, ARA Authority is requesting USACE and NCDEQ permit modification to the prior issued
permits to complete installation of additional site controls and for the proposed additional impacts
to waters of the U.S. (WOTUS), as regulated under Section 404 and 401 of the Clean Water Act,
respectively. The USACE ENG Form 4345 Application for the project is provided in Appendix
A.
Area 1 is located south of Asheville and West of Fletcher in Buncombe County, North Carolina
(Figure 1) within the ARA property, as illustrated on the Skyland U.S. Geological Survey (USGS)
7.5-minute Quadrangle Map (Figure 2). The latitude and longitude for Area 1 is latitude:
35.44588°N; longitude 82.54206°W. Area 1 is located on an unnamed tributary within the French
Broad Watershed (Hydrologic Unit Code 06010105) approximately 0.7 miles upstream (south) of
the French Broad River (Figure 3).
3.1 Background
Area 1 is an 18-acre (ac) CCR structural fill situated near the northeastern ARA property boundary
and was constructed pursuant to a contract between Charah and the ARA Authority, to expand
airport operations in 2008 to 2010 period. The Area 1 footprint formerly consisted of a topographic
valley prior to construction and contained a historical stream channel that flowed northward from
the property. The historical stream channel traverses a residential area situated on the northern
property boundary adjacent to Area 1 before discharging into the French Broad River.

Area 1 was constructed by filling the topographic valley with CCR purchased by Charah from
Duke Energy's Asheville Steam Electric Plant. The historical stream channel was re-routed
upgradient of Area 1 within a 54-inch (in.) diameter reinforced concrete pipe (RCP) and a concrete
junction box was installed to transition from the 54-in. to a 60-in. diameter RCP bedded with
drainage aggregate beneath the Area 1 footprint. The historical stream channel branch west of the
60-in. diameter RCP was also filled with drainage aggregate and covered. The 60-in. diameter
RCP flows into a concrete junction box with a 15-in. diameter RCP with headwall that discharges
as base flow to the northwest and a 60-in. diameter RCP with headwall that discharges to the north.
The structural fill resulted in impacts to WOTUS and was authorized in 2008 by a USACE CWA
Section 404 permit (SAW-2007-03766-311) and by a NCDEQ CWA Section 401 permit (DWQ
#20071841).
As -built drawings prepared by Charah (Appendix B) indicate that Area 1 was constructed with a
geosynthetic clay liner (GCL) base liner and vegetated soil cap system. Soil backfill was
compacted on the GCL above and within 50 feet (ft) of the 60-in. RCP that divides the Area 1
structural fill into western and eastern components. The existing soil cap system was constructed
with approximately 6-ft and 2-ft thick soil layers on the top deck and side slopes, respectively. The
original soil cap was designed with the anticipation that impervious surface would be constructed
over the soil cap thereby largely eliminating infiltration of rain and surface water. The impervious
surface was not constructed and in August 2019, NCDEQ requested that a permanent cap system
be designed to "abate the infiltration of groundwater and/or precipitation into Area 1" and "to abate
or control ... seepage water".

4. PROJECT PURPOSE AND NEED
Geosyntec°
consultants
c.o:me=con,muoaorne, r.�.
The purpose for the project is to install site controls for stabilization of the structural fill at Area
1. These additional site controls will enable the ARA Authority to continue forward with their
development plans for Area 1 to facilitate airport expansion authorized by prior CWA Section 404
and 401 permits.
The primary site controls being installed are (1) a nonpermeable permanent cap layer over the
previously placed structural fill at Area 1 and (2) develop two sediment basins that will be
converted to stormwater basins (dry detention) post -construction to meet required regulatory
stormwater runoff capture requirements for Area 1 cap system.
The need of the permanent cap is to reduce infiltration of water into the existing structural fill to
comply with NCDEQ Solid Waste requirements for addressing Area 1. Secondarily, the project
will meet required regulatory stormwater runoff capture requirements via construction of erosion
and sediment control and stormwater features. The installation will consist of a composite soil
geomembrane liner system and construction of two stormwater basins to capture runoff from the
permanent cap.

consultants
c.o:me=con,muoaorne, r.�.
Geosyntec Consultants of NC, PC (Geosyntec) performed a field visit on 24 February 2021 to
observe existing conditions within and adjacent to Area 1. Area 1 is bound on the west and south
by developed airport operations. Area 1 is bound to the east by Interstate-26 and Area 1 is bound
to the north by existing sediment basins, stormwater basin, wetlands, and streams and then by a
residential development. Two defunct sediment basins are present along the northern boundary of
area 1; sediment basin 1 is located near the northeast corner of Area 1 and sediment basin 2 is
located near the northwest corner of Area 1 (Figure 3). Area 1 consists of maintained vegetative
turf. The vegetative community north of, and adjacent to, Area 1 is predominately hardwood forest
dominated by red maple (Acer rubrum), tulip tree (Liriodendron tulipifera), jewelweed (Impatiens
capensis), soft rush (Juncus effusus), an unknown sedge species (Carex spp.), and Virginia creeper
(Parthenocissus quinquefolia). Soils within the project area consist of Tate loam, Clifton and
Evard clay loam, and Udorthents sandy clay loam according to the Natural Resources
Conservation Service (NRCS) county soils data (Figure 4).
5.1 Jurisdictional Wetlands/Waters
At the request of Duke Energy, Wood Environment & Infrastructure Solutions, Inc. (Wood)
performed a wetlands and waterbody delineation within the project area, which identified four
jurisdictional streams and one jurisdictional wetland. Wood prepared and submitted a USACE
Approved Jurisdictional Determination (AJD) form (Appendix C). Amanda Fuemmeler of the
USACE conducted a site review for the verification of the JD on 28 January 2020.
The jurisdictional features identified include one jurisdictional wetland and four perennial streams
(Figure 5). Geosyntec conducted field assessments of the jurisdictional wetland and streams in the
project area following the North Carolina Wetland Assessment Methodology (NCWAM) and
North Carolina Stream Assessment Methodology (NCSAM) during the February 2021 field visit.
The NCWAM and NCSAM forms are provided in Appendix D. Details of the wetland and streams
are included in Table 1 and are described in further detail below.

Wetland WB is a 1.52-ac non -tidal freshwater wetland (North Carolina Wetland Type) located
within a topographic depression immediately north of and adjacent to Area 1 and is associated
with the floodplain of the four existing perennial streams. Vegetation is dominated by red maple
(Acer rubrum), tulip tree (Liriodendron tulipifera), jewelweed (Impatiens capensis), soft rush
(Juncus effusus), an unknown sedge species (Carex spp.), and Virginia creeper (Parthenocissus
quinquefolia). The wetland was previously affected by runoff and prior site construction. A large
berm is present within Wetland WB. Further, wetland hydrology has been affected by runoff from
the airport and adjacent Interstate-26. An NCWAM evaluation of Wetland WB rates the quality of
the wetland as medium, due to its size, connection to the stream channels, potential to intercept
pollutants, moderate habitat structure, and vegetative composition.
Stream SA (227 LF) is an existing perennial stream that daylights (runs underground beneath Area
1) at the northwest toe of Area 1. The width of the channel is between 6 and 15 ft and is
hydrologically connected to Wetland WB in the upper reach but loses connection due to channel
incision in the lower reach. Stream SA flows south to north to a culvert at the northern property
boundary which restricts flow off property and causes flooding (e.g., impounds surface water
during storm events within the project area and Wetland WB and Stream SA). Additionally,
Stream SA receives runoff from the upland areas which include airport operations. The stream
ultimately discharges into the French Broad River approximately one mile north of the project
boundary.
Stream SB (239 LF) is a perennial stream that originates near the eastern boundary of Area 1 and
flows into Wetland WB before reemerging as Stream SD. The stream receives runoff from I-26
and the adjacent residential area. The width of the stream channel is between 7 and 10-ft. Stream

SC (103 LF) is a perennial stream that extends along the edge of Wetland WB and discharges into
Stream SA. The width of the stream channel is between 2 and 4-ft.
Stream SD (48 LF) is a perennial stream along the northern property boundary that receives runoff
from I-26 and the adjacent residential area. A NCSAM evaluation of the stream channels rates the
quality of Stream SA, Stream SB, and Stream SD as medium and Stream SC as low due to their
hydrologic connection to Wetland WB, heavily developed drainage basin, adjacent land use, and
altered geomorphic pattern and profile.
5.2 Protected Species
Geosyntec performed a desktop review of federally listed species that potentially occur in the
project area. Data was obtained from the U.S. Fish and Wildlife Service (USFWS) Environmental
Conservation Online System (ECOS) Information Planning and Consultation (IPaC) web
application (accessed 16 February 2021 and updated 07 June 2021) and is provided in Appendix
E. The results indicated that 8 federally listed species including five listed endangered and three
listed threatened could have suitable habitat or be present at the site. Geosyntec performed a
preliminary protected species assessment during the February 2021 site visit to evaluate the
potential presence and absence of protected species and their habitat. Results of this assessment
indicate that no suitable habitat exists within, or immediately adjacent to the project area, for
federally listed species. Table 2 briefly describes known habitat for each of these species and
includes an evaluation of presence of habitat within the project area.

ARA property pursuant to Section 106 of the National Historic Preservation Act (NHPA). This
area was comprised of previously disturbed soils from the 2008 to 2010 structural fill placement
and a portion of this area will require construction of two new stormwater basins for the permanent
cap.
RSWA submitted (via e-mail) a request for Environmental Review to the North Carolina SHPO
on 23 March 2021. North Carolina SHPO responded to the Environmental Review request on 22
April 2021 and stated that no further archaeological investigations are warranted for the project
and that the proposed project will not affect any historic properties or cultural resources (Appendix
F).

6. PROJECT DESCRIPTION
Geosyntec°
consultants
c.o:me=con,muoaorne, r.�.
ARA Authority (property owner and applicant), in collaboration with Duke Energy (engineering
and construction of permanent cap), is proposing to construct a nonpermeable permanent cap layer
system for Area 1 to prevent infiltration of water into the structural fill. This remedy will comply
with NCDEQ Solid Waste requirements to reduce infiltration of water and remedy the seeps. The
new cap design will also achieve required stormwater runoff capture requirements (Appendix G).
The project consists of a composite soil geomembrane liner system designed to prevent and
minimize surface water infiltration into Area 1 structural fill, manage surface water, and limit
hydraulic head on the geomembrane. The project is comprised of two components: 1)
nonpermeable permanent cap layer system and 2) two sediment basins that will be converted to
stormwater basins (dry detention) post -construction. Note, the current design of the permanent cap
was authorized by NCDEQ Solid Waste Section on 16 December 2020 (Appendix H).
The project does not include placement of additional structural fill and will not excavate in the
existing structural fill (CCR). The permanent cap will be installed entirely within uplands, is
designed to abate and control seepage water from the structural fill, shed surface water, and to
drain water infiltrated within the cap to minimize potential ponding atop the geomembrane layer.
Stormwater drainage is designed to limit route length and will be conveyed in three general
directions off the cap: (i) east-northeast to east stormwater basin; (ii) west then northwest to west
stormwater basin; and (iii) south to an existing stormwater channel towards Wright Brothers Way
(Appendix G; Sheet 3).
The two existing sediment basin remnants (they were partially decommissioned to prevent
retention of water at toe of slope) present along the northern boundary of Area 1 (Figure 3) will
be re -configured and converted to two new stormwater basins (east stormwater basin and west
stormwater basin) (Figure 6). The stormwater basins will capture and detain additional drainage
flows from the permanent cap to achieve stormwater runoff capture requirements (Appendix G;
Sheet 3 and 6). Due to the existing topography of the area, existing site constraints including
airport operations to the west and south and Interstate-26 to the east, and the need to minimize
ponding atop the geomembrane layer, the north side of Area 1 is the only practicable location for
the two stormwater basins. The stormwater basins were designed following the NCDEQ
Stormwater Design Manual and the NCDEQ Erosion and Sediment Control Planning and Design
Manual, which specify embankment slopes (3H:1V) as well as basin shape (at least 2:1 flow length
to width ratio), both of which influenced the final design configuration and extents. During
construction and post -construction the stormwater basins will also be used as a sediment basin.
The stormwater basins are also designed as dry detention to release stormwater within 48 hours
pursuant to Federal Aviation Administration (FAA) regulations as not to attract nuisance wildlife.
An existing underground stream under Area 1 (Stream SA) daylights at the northwest toe of Area
1 and contributed to erosion of the existing perimeter sediment basin 2 dike structure. As such, a

rock drain is proposed to convey the base stream flow beneath the new stormwater basin
(Appendix G; Sheet 6); while an outlet control structure and perimeter berm is proposed to retain
stormwater runoff prior to release into the existing stream.
The construction of the stormwater basins will result in approximately 0.56-acre of impacts to
Wetland WB and the installation of the outlet control structure will result in 12 LF of permanent
fill impacts to the Stream SA.

Geosyntec°
consultants
c.o:me=c.o,muncsof r.�.
The project was designed to avoid and minimize impacts to aquatic resources to the greatest extent
practicable while meeting the project purpose and need. The proposed construction of the two
stormwater basins is needed to manage the construction and post -construction stormwater runoff
and sediment. The basins will facilitate installation of the permanent cap and will capture and
detain additional drainage flows from the permanent cap to achieve stormwater runoff capture
requirements.
Due to the existing topography of the area, existing site constraints including airport operations to
the west and south and Interstate-26 to the east, and the need to minimize ponding atop the
geomembrane layer, the north side of Area 1 is the only practicable location for the two stormwater
basins. The stormwater basins were designed following the NCDEQ Stormwater Design Manual
and the NCDEQ Erosion and Sediment Control Planning and Design Manual, which specify
embankment slopes (3H:1V) as well as basin shape (at least 2:1 flow length to width ratio), both
of which influenced the final design configuration and extents.
The stormwater basins are also designed as dry detention to release stormwater within 48 hours
pursuant to FAA regulations as not to attract nuisance wildlife. The construction of the two basins
(east and west basins) with perimeter berms and outlet control structures will result in permanent
fill impacts of approximately 0.56-acre to Wetland WB (Figure 6) and approximately 12 LF to
Stream SA (Table 3).

8. ALTERNATIVES ANALYSIS
Geosyntec°
consultants
c.o:me=coo,muoaorne, r.�.
Section 404(b)(1) of the Clean Water Act stipulates that no discharge of dredge or fill material into
waters of the U.S., which include wetlands, shall be permitted if there is a practicable alternative
which would have less adverse impact on the aquatic ecosystem, so long as the alternative does
not have other significant environmental consequences. Other non -water related impacts are also
evaluated to determine the environmental impacts of the alternatives to appropriately assess and
determine the preferred alternative which is considered the LEDPA.
The following alternatives analysis discussion evaluates potential alternatives for the proposed
project and considers the most appropriate methods to achieve project objectives. This alternatives
analysis was based on the following:
• The construction of the Area 1 structural fill to expand airport operations received CWA
Section 404 and 401 permit authorizations (USACE SAW-2007-03766-311 and NCDEQ
DWQ #20071841). The purpose and need of the structural fill is still being met and ARA
Authority intends to utilize Area 1 for airport operations expansion following completion
of the permanent cap system.
• The structural fill was identified as the LEDPA in the original application and was
approved by both NCDEQ and USACE.
• Removal of the structural fill in whole (either onsite or offsite placement) or part
(reconsolidation in Area 1) were not valid alternatives due to environmental complexity of
such operations and lack of suitable locations to receive the material. As such, further
offsite and onsite siting alternatives for structural fill placement were not considered other
than methods to institute site controls to bring the structural fill in compliance with
NCDEQ and to allow the ARA Authority to pursue development of Area 1.
• This permit application and the alternatives analysis were prepared to address the NCDEQ
notice of violation (NOV) and remedial action to limit surface water infiltration into the
structural fill, address seepage, and control stormwater from the Area 1 permanent cap
discussed herein.
The structural fill was closed in place with a permanent soil cap meeting NCDEQ requirements in
2010. The original soil cap was designed with the anticipation that impervious surface would be
constructed over the soil cap thereby largely eliminating infiltration of rain and surface water. The
impervious surface was not constructed following completion of the soil cap in 2010. Since 2010,
the appearance of seeps has necessitated an alternate cap remedy to achieve compliance with an
NOV from NCDEQ. Therefore, since the structural fill is to continue to serve its purpose and need,
further offsite and onsite alternatives were determined to not be practicable and that on -site

construction of site controls to bring the site in compliance with NCDEQ through construction of
a nonpermeable permanent cap layer system for the structural fill and associated stormwater basins
is the least environmentally damaging practicable solution for the project that meets the project
purpose and need.
The alternatives analysis provided herein addresses the design of the new permanent cap and the
stormwater management control for the permanent cap.
8.1 Preferred Alternative
The applicant's preferred alternative is to construct a permanent cap for Area 1 (Appendix G).
The proposed project consists of a composite soil geomembrane liner system designed to prevent
and minimize surface water infiltration into Area 1 structural fill, manage surface water, and limit
hydraulic head on the geomembrane. The preferred alternative is comprised of two components:
1) nonpermeable permanent cap layer system and 2) sediment and stormwater basins (dry
detention). The preferred alternative includes a minimum 3-feet of cover over the capped material
along the side slopes and top deck to allow for drainage and vegetative soil layers to support
vegetation growth on the cap.
Due to the existing topography of the area, existing site constraints including airport operations to
the west and south and Interstate-26 to the east, and the need to minimize ponding atop the
geomembrane layer, the north side of Area 1 is the only practicable location for the two stormwater
basins. Therefore, total avoidance of impacts to WOTUS was not practical. The preferred
alternative was designed to minimize and avoid adverse impacts to wetlands/waters to the
maximum extent practicable, which was accomplished by (i) minimizing the overall disturbed
acreage to the site, and (ii) by minimizing and avoiding impacts to aquatic resources located within
the project area. The extent of the stormwater basins was minimized to the extent practical while
also adhering to NCDEQ design guidelines for embankment slopes (3:1 slopes) and flow length
to width ratio (2:1) and meeting the required the stormwater capture requirements. Additional
avoidance and minimization measures are provided in Section 9.
The preferred alternative will result in permanent impacts to WOTUS, including 12 LF of
perennial stream and 0.56-ac of wetland.
8.2 No Action Alternative
Under the No Action (No -Build) Alternative, the proposed project would not be constructed, and
the purpose and need would be unfulfilled. A No -Build Alternative for this project is not a viable
option since NCDEQ's NOV would not be addressed leaving the structural fill in non-compliance.
Duke Energy is required to remediate the infiltration into the CCR structure fill to resolve the
NOV. Therefore, Duke Energy is required to construct a new permanent nonpermeable cap to

c.o:me=con,muoaorne, r.�.
attain compliance with the NOV and additionally manage stormwater on the permanent cap which
necessitates stormwater controls, which must be located downgradient. Further, the stormwater
basins must be designed to release stormwater within 48 hours pursuant to FAA regulations as not
to attract nuisance wildlife. Abandoning the project would not fulfill the project purpose and need
and would result in non-compliance with NCDEQ Solid Waste Section order.
8.3 Alternative 1
Alternative 1 was initially considered by in 2019. As with the Preferred Alternative, Alternative 1
design is comprised of two components: (i) nonpermeable permanent cap layer system and (ii)
sediment and stormwater surface water basins (dry detention). The design included similar
components of the preferred alternative but a thinner cover layer than the Preferred Alternative's
3-ft layer. Further, this design included a different configuration for the constructed stormwater
basins that resulted in 0.07 acre more of wetland impacts (0.63 acre total) and 14.3 LF (26.3 LF
total) more of perennial stream impacts than the preferred alternative.
8.4 Alternative Selection
To fulfill the project purpose and need and achieve the LEDPA, the preferred alternative was
selected as the applicant's preferred project for further environmental analysis since it achieved
the greatest avoidance and minimization of impacts to aquatic resources.

9. AVOIDANCE AND MINIMIZATION
Geosyntec°
consultants
c.o:me=con,muoaorne, r.�.
The Preferred Alternative was designed to minimize and avoid adverse impacts to wetlands/waters
to the maximum extent practicable and was accomplished by (i) minimizing the overall disturbed
acreage to the site, and (ii) by minimizing and avoiding impacts to aquatic resources located within
the project area. The Preferred Alternative avoids impacts to 605 LF of perennial streams and 0.96-
ac of wetlands within the project area. The Preferred Alternative's adverse impacts are provided
in Table 4. The following minimization and avoidance measures were used in design of the
permanent cap:
• The extent of the stormwater basins were reduced from the original design, reducing
impacts to Wetland WB from 0.63-ac to 0.56-ac. Additionally, the design of the outlet
control structure at stormwater basin 2 was reduced from the original design, reducing
impacts to Stream SA from 26.3 LF to 12 LF.
• All material used as fill on this project will be from clean, uncontaminated sources and free
of cultural resources.
• No impacts will occur to Stream SB, Stream SC, or Stream SD.
• A NCDEQ approved Erosion, Sedimentation, and Pollution Control Plan will be
implemented on -site prior to and during construction activities to minimize threats of
sedimentation reaching downstream waters.
• No construction activity or stockpiling will occur in WOTUS, including wetland areas,
outside of the areas authorized for filling under this permit.
• Prior to the commencement of construction activities for this project, the limits of the
proposed fill areas in jurisdictional waters will be clearly flagged and staked. All
construction personnel will be shown the location(s) of all wetland and/or stream areas
outside of the construction area to prevent encroachment from heavy equipment into these
areas.
• Staging areas and equipment maintenance areas will be located at least 200 feet from
streambanks to minimize the potential for wash water, petroleum products, or other
contaminants from construction equipment entering the streams.
• The projects master drainage plan is designed to avoid inadvertent drainage of wetlands
and inadvertent water diversion resulting in a reduction of hydrology in wetlands.
• Bank erosion and sedimentation in construction areas will be minimized by utilizing Best
Management Practices for stream corridors, installing, and maintaining significant erosion

consultants
c.o:me=c.n,muncsof r.�.
At the time of this permit application, no listed mitigation banks within the French Broad Basin
(HUC 06010105) have wetland mitigation credits available for purchase. As such, mitigation for
permanent impacts to jurisdictional wetlands will be accomplished by purchasing credits from the
NCDEQ Division of Mitigation Services (DMS) In-Leu Fee (ILF) program. Only one mitigation
bank possessed cool water stream credits (Anderson Farm Mitigation Bank) in the French Broad
Basin. Due to the small amount of stream credits required for the project, the USACE has indicated
that the projects compensatory mitigation for stream and wetland credits be secured through the
DMS ILF program. As such, the ARA Authority will submit a mitigation purchase request form
to the DMS ILF program to secure wetland and stream compensatory mitigation for the project.

14. CONCLUSION
Geosyntec°
consultants
c.o:me=con,muoaorne, r.�.
ARA Authority (property owner and applicant), in collaboration with Duke Energy (engineering
and construction of permanent cap), is proposing to construct a nonpermeable permanent cap layer
system for Area 1 to prevent infiltration of water into the structural fill. The need of the permanent
cap is to institute necessary site controls for stabilization of the structural fill to comply with
NCDEQ Solid Waste requirements for containment of CCR at Area 1 (reduce infiltration of water
into existing soil cap for CCR structural fill) and meet required regulatory stormwater runoff
capture requirements The project consists of a composite soil geomembrane liner system designed
to prevent and minimize surface water infiltration into Area 1 structural fill, manage surface water,
and limit hydraulic head on the geomembrane. The project is comprised of two components: 1)
permanent nonpermeable cap layer system and 2) two sediment basins will be converted to
stormwater basins (dry detention) post -construction. The permanent cap will be installed entirely
within uplands and is designed to shed surface water and to drain water infiltrated within the cap
to minimize potential ponding atop the geomembrane layer. The new cap system has also been
designed to allow the ARA Authority to use Area 1 for expansion of airport operations as originally
planned under the prior issued permits.
An alternatives analysis was performed for the project to identify the LEDPA. The preferred
alternative was identified as the LEDPA as it met the project purpose and need of the project while
minimizing cumulative impacts to areas aquatic resources. Cumulative permanent impacts include
12 LF of perennial stream and 0.56-ac of wetland. While impacts to wetlands/waters are necessary,
the project has avoided and minimized impacts to the maximum extent practicable (avoided 605
LF of stream and 0.96 ac of wetlands). Sixty-three percent (63%) of wetlands and 98% of perennial
streams of on -site wetlands/waters were avoided by the project. The footprint of the east and west
stormwater basins were reduced from the original design, further reducing impacts to Wetland WB
from 0.63-ac to 0.56-ac. Additionally, the design of the outlet control structure on the east
stormwater basin was reduced from the original design, reducing impacts to Stream SA from 26.3
LF to 12 LF. To mitigate for permanent impacts to jurisdictional wetlands and waters, Duke
Energy will purchase credits from the NCDEQ DMS ILF program for wetlands and for cool water
stream credits.
Protected species or their respective habitats were not observed within, or immediately adjacent to
the project area and therefore, the proposed project would not affect federally listed species.
Further, based on the preliminary cultural resources survey performed by RSWA, the proposed
project would not adversely affect any known historic properties included in or eligible for
inclusion in the National Register of Historic Places and the project is not expected to require
additional coordination with SHPO.

17. DIRECTIONS TO THE SITE
The closest location to the entrance is 275 Wright Brothers Way, Arden, NC 28704. From there, clearance is required to enter Airport
property.
18. Nature of Activity (Description of project, include all features)
Duke Energy is proposing to construct a permanent cap for Area 1 to comply with NCDEQ Solid Waste requirements for containment of
CCR and to achieve required stormwater runoff capture requirements. The proposed project consists of a composite soil geomembrane liner
system designed to prevent and minimize surface water infiltration into Area 1 structural fill, manage surface water, and limit hydraulic head
on the geomembrane. Two stormwater basins will be constructed to manage the construction and post -construction stormwater runoff and
sediment. The stormwater basins will also facilitate installation of the permanent cap and achieve stormwater runoff capture requirements.
The stormwater basins are also designed as dry detention to release stormwater within 48 hours pursuant to Federal Aviation Administration
(FAA) regulations as not to attract nuisance wildlife.
Further details of the project are provided in Section 6 of Individual Permit Application package and supporting documents
19. Project Purpose (Describe the reason or purpose of the project, see instructions)
The primary purpose for the project is to install a remedial nonpermeable permanent cap (permanent cap) over CCR previously used as
structural fill at Area 1 of the ARA. The purpose of the permanent cap is to comply with NCDEQ Solid Waste requirements for containment
of CCR and meet required regulatory stormwater runoff capture requirements. The installation will consist of a composite soil geomembrane
liner system and establishing two stormwater basins to capture runoff from the remedial cap.
USE BLOCKS 20-23 IF DREDGED AND/OR FILL MATERIAL IS TO BE DISCHARGED
20. Reason(s) for Discharge
The construction of two stormwater basins is needed to manage the construction and post -construction stormwater runoff and sediment. The
re -graded basins will also facilitate installation of the permanent cap and achieve stormwater runoff capture requirements. The stormwater
basins are also designed as dry detention to release stormwater within 48 hours pursuant to FAA regulations as not to attract nuisance wildlife.
TThe construction of the stormwater basins will result in approximately 0.56-acre of impacts to Wetland WB and the installation of the outlet
control structure will result in 12 LF of permanent fill impacts to the Stream SA
21. Type(s) of Material Being Discharged and the Amount of Each Type in Cubic Yards:
Type Type Type
Amount in Cubic Yards Amount in Cubic Yards Amount in Cubic Yards
Clean fill - 4,122.5
22. Surface Area in Acres of Wetlands or Other Waters Filled (see instructions)
Acres 0.56 acre of wetland
or
Linear Feet 12 linear feet of perennial stream
23. Description of Avoidance, Minimization, and Compensation (see instructions)
The proposed project was designed to minimize and avoid adverse impacts to wetlands/waters to the maximum extent practicable and was
accomplished by (i) minimizing the overall disturbed acreage to the site, and (ii) by minimizing and avoiding impacts to aquatic resources
located within the project area. The project would avoid impacts to 606 LF of perennial streams and 0.96-ac of wetlands. Refer to permit
application package for more information detailing the extent of the impacts, minimization and avoidance measures.
Further details of avoidance and minimization are provided in Section 9 of Individual Permit Application package

waters list, do NOT use this document to make the determination. The District must continue to follow the procedure outlined in 33 CFR part 329.14 to
make a Rivers and Harbors Act Section 10 navigability determination.
3 A stand-alone TNW determination is completed independently of a request for an AJD. A stand-alone TNW determination is conducted for a specific
segment of river or stream or other type of waterbody, such as a lake, where upstream or downstream limits or lake borders are established. A stand-
alone TNW determination should be completed following applicable guidance and should NOT be documented on the AJD Form.

document and/or references/citations in the administrative record, as appropriate.
❑ Information submitted by, or on behalf of, the applicant/consultant: Title(s) and date(s)
This information Select. sufficient for purposes of this AJD.
Rationale: N/A or describe rationale for insufficiency (including partial insufficiency).
❑ Data sheets prepared by the Corps: Title(s) and/or date(s).
❑x Photographs: Aerial: Figure 2 —Aerial Photograph (11/9/2020) (attached)
❑ Corps site visit(s) conducted on: Date(s).
❑ Previous Jurisdictional Determinations (AJDs or PJDs): ORM Number(s) and date(s).
4 Some excluded waters, such as (b)(2) and (b)(4), may not be specifically identified on the AJD form unless a requestor specifically asks a Corps district
to do so. Corps districts may, in case -by -case instances, choose to identify some or all of these waters within the review area.
5 Because of the broad nature of the (b)(1) exclusion and in an effort to collect data on specific types of waters that would be covered by the (b)(1)
exclusion, four sub -categories of (b)(1) exclusions were administratively created for the purposes of the AJD Form. These four sub -categories are not
new exclusions, but are simply administrative distinctions and remain (b)(1) exclusions as defined by the NWPR.

Subject: Updated list of threatened and endangered species that may occur in your proposed
project location or may be affected by your proposed project
To Whom It May Concern:
The attached species list identifies threatened, endangered, proposed and candidate species, as
well as proposed and final designated critical habitat, that may occur within the boundary of your
proposed project and/or may be affected by your proposed project. Although not required by
section 7, many agencies request species lists to start the informal consultation process and begin
their fulfillment of the requirements under section 7(c) of the Endangered Species Act (Act) of
1973, as amended (16 U.S.C. 1531 et seq.).
This list, along with other helpful resources, is also available on the U.S. Fish and Wildlife
Service (Service) —Asheville Field Office's (AFO) website: hops://www.fws.gov/raleigh/species/
cntylist/nccounties.html. The AFO website list includes "species of concern" — species that
could potentially be placed on the federal list of threatened and endangered species in the future.
Also available are:
• Design and Construction Recommendations

• Predictive Habitat Model for Aquatic Species
https://www.fws.gov/asheville/htmls/Maxent/Maxent.html
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could require modifications of these lists.

06/07/2021
Event Code: 04EN1000-2021-E-01524 2
Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act,
the accuracy of the species lists should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website or the AFO website (the AFO website dates each
county list with the day of the most recent update/change) at regular intervals during project
planning and implementation for updates to species lists and information. An updated list may
be requested through the ECOS-IPaC system by completing the same process used to receive the
enclosed list or by going to the AFO website.
The purpose of the Act is to provide a means whereby threatened and endangered species and the
ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of
the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to
utilize their authorities to carry out programs for the conservation of threatened and endangered
species and to determine whether projects may affect threatened and endangered species and/or
designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having
similar physical impacts) that are major Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)
(c)). For projects other than major construction activities, the Service suggests that a Biological
Evaluation similar to a Biological Assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a Biological Assessment are described at 50 CFR 402.12 and on our office's website
at https://www.fws.gov/asheville/htmis/project review/assessment guidance.html.
If a Federal agency (or their non-federal representative) determines, based on the Biological
Assessment or Biological Evaluation, that listed species and/or designated critical habitat may be
affected by the proposed project, the agency is required to consult with the Service pursuant to
50 CFR 402. In addition, the Service recommends that candidate species, proposed species, and
proposed critical habitat be addressed within the consultation. More information on the
regulations and procedures for section 7 consultation, including the role of permit or license
applicants, can be found in the "Endangered Species Consultation Handbook" at: http://
www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF.
Though the bald eagle is no longer protected under the Endangered Species Act, please be aware
that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16
U.S.C. 668 et seq.), and projects affecting these species may require additional consultation (see
hops://www.fws.gov/southeast/our-services/permits/eagles/). Wind energy projects should
follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to
migratory birds (including bald and golden eagles) and bats.
Guidance for minimizing impacts to migratory birds for projects including communications
towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http://

Project Summary
Consultation Code: 04EN1000-2021-SLI-0563
Event Code: 04EN1000-2021-E-01524
Project Name: ARA Area 1 Structural Fill
Project Type: FILL
Project Description: Construction of a permanent cap for Area 1 to comply with NCDEQ Solid
Waste requirements for containment of CCR and to achieve required
stormwater runoff capture requirements. Area 1 is located south of
Asheville and West of Fletcher in Buncombe County, North Carolina.
The project consists of a composite soil geomembrane liner system
designed to prevent and minimize surface water infiltration into Area 1
structural fill, manage surface water, and limit hydraulic head on the
geomembrane. The project is comprised of two components: 1) permanent
nonpermeable cap layer system and 2) sediment and stormwater basins
(dry detention).
The permanent cap will be installed entirely within previously disturbed
uplands and is designed to shed surface water and to drain water
infiltrated within the cap to minimize potential ponding atop the
geomembrane layer. Stormwater drainage is designed to limit route length
and will be conveyed in three general directions off the cap: (i) east-
northeast to east stormwater basin; (ii) west then northwest to west
stormwater basin ; and (iii) south to an existing stormwater channel
towards Wright Brothers Way
Two stormwater basins will be constructed on the north side of Area 1 to
capture and detain stormwater to achieve stormwater runoff capture
requirements. During construction and post -construction the stormwater
basins will also be used as a sediment basin. The stormwater basins are
also designed as dry detention to release stormwater within 48 hours
pursuant to Federal Aviation Administration (FAA) regulations as not to
attract nuisance wildlife.
An existing underground stream under Area 1 daylights at the northwest
toe of Area 1 and contributed to erosion of the existing perimeter
sediment basin 2 dike structure. As such, a rock drain is proposed to
convey the base stream flow beneath the new stormwater basin; while an
outlet control structure and perimeter berm is proposed to retain
stormwater runoff prior to release into the existing stream.
The construction of the stormwater basins will result in approximately
0.56-acre of impacts to wetland and the installation of the outlet control

06/07/2021

structure will result in 12 LF of permanent fill impacts to perennial
stream. The project will not result in the removal of trees.

Endangered Species Act Species
There is a total of 8 threatened, endangered, or candidate species on this species list.
Species on this list should be considered in an effects analysis for your project and could include
species that exist in another geographic area. For example, certain fish may appear on the species
list because a project could affect downstream species.
IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA
Fisheriesl, as USFWS does not have the authority to speak on behalf of NOAA and the

Migratory Birds
Certain birds are protected under the Migratory Bird Treaty Act1 and the Bald and Golden Eagle
Protection Actz.
Any person or organization who plans or conducts activities that may result in impacts to
migratory birds, eagles, and their habitats should follow appropriate regulations and consider
implementing appropriate conservation measures, as described below.
1. The Migratory Birds Treaty Act of 1918.
2. The Bald and Golden Eagle Protection Act of 1940.
3. 50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)
The birds listed below are birds of particular concern either because they occur on the USFWS
Birds of Conservation Concern (BCC) list or warrant special attention in your project location.
To learn more about the levels of concern for birds on your list and how this list is generated, see
the FAQ below. This is not a list of every bird you may find in this location, nor a guarantee that
every bird on this list will be found in your project area. To see exact locations of where birders
and the general public have sighted birds in and around your project area, visit the E-bird data
mapping tool (Tip: enter your location, desired date range and a species on your list). For
projects that occur off the Atlantic Coast, additional maps and models detailing the relative
occurrence and abundance of bird species on your list are available. Links to additional
information about Atlantic Coast birds, and other important information about your migratory
bird list, including how to properly interpret and use your migratory bird report, can be found

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 and understand the
FAQ "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.

06/07/2021
Event Code: 04EN1000-2021-E-01524 3
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.
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 (I)
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.
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.

Migratory Birds FAQ
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 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 migratory birds potentially occurring 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

06/07/2021
Event Code: 04EN1000-2021-E-01524 5
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 AKN Phenology 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, migrating or present year-round in my
project 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 refer to the following resources: The Cornell Lab
of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of
interest there), the Cornell Lab of Ornithology Neotropical Birds guide. 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

06/07/2021
Event Code: 04EN1000-2021-E-01524 6
implement to help avoid and minimize migratory bird impacts and requirements for eagles,
please see the FAQs for these topics.
Details about birds that are potentially affected by offshore projects
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.
What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid
violating the Eagle Act should such impacts occur.
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.

Please give a brief project description below and include location information.*

Duke Energy Progress, LLC (Duke Energy) is proposing to install a
remedial nonpermeable permanent cap (permanent cap) over coal
combustion residuals (CCR) used as structural fill at Area 1 of the
Asheville Regional Airport (ARA) in Buncombe County, North
Carolina. Area 1 is an 18-acre, CCR structural fill situated near the
northeastern ARA property boundary and was previously constructed
to expand airport operations. As -built drawings prepared by Charah
in 2010 indicate that Area 1 was constructed with a geosynthetic clay
liner (GCL) base liner and soil cap system. Soil backfill was
compacted on the GCL above and within 50 feet of the 60-in. RCP
that divides the Area 1 structural fill into western and eastern
components. The existing soil cap system was constructed with
approximately 6-ft and 2-ft thick soil layers on the top deck and side
slopes, respectively. In August 2019, NCDEQ requested that a
permanent cap system be designed to "abate the infiltration of
groundwater and/or precipitation into Area 1" and "to abate or control
...seepage water".
Duke Energy is proposing to construct a permanent cap for Area 1 to
comply with NCDEQ Solid Waste regulations for containment of CCR
and to achieve required stormwater runoff capture requirements
(Project). The proposed Project consists of a composite soil
geomembrane liner system designed to prevent and minimize surface
water infiltration into Area 1 structural fill, manage surface water, and
limit hydraulic head on the geomembrane. The proposed Project is
comprised of two components: 1) permanent non -permeable cap
layer system and 2) sediment and stormwater surface water ponds
(dry detention).
The permanent cap will be installed entirely within uplands and is
designed to shed surface water and to drain water infiltrated within
the cap to minimize potential ponding atop the geomembrane layer.
Stormwater drainage is designed to limit route length and will be
conveyed in three general directions off the cap: (i) east-northeast to
stormwater pond 1; (ii) west then northwest to stormwater pond 2;
and (iii) south to an existing stormwater channel towards Wright
Brothers Way.
Two existing sediment basins will be redeveloped and re -graded to
manage the construction and post -construction stormwater runoff
and sediment. The re -graded basins will also facilitate installation of
the permanent cap and achieve stormwater runoff capture
requirements. The surface water ponds are also designed as dry
ponds to release stormwater within 48 hours pursuant to Federal
Aviation Administration (FAA) regulations as not to attract nuisance
wildlife.
An existing underground stream (Unnamed Tributary to French Broad
River) daylights at the northwest toe of Area 1 and contributed to
erosion of the existing perimeter pond dike structure. As such, a rock
drain is proposed to convey the base stream flow beneath the pond;
while an outlet control structure and perimeter berm is proposed to
retain stormwater runoff prior to release into the existing stream.
The redevelopment and re -grading of the stormwater ponds will result
in approximately 0.56-acre of impacts to a non -tidal freshwater marsh
by stormwater pond and the installation of the outlet control structure
will result in 12 linear feet of permanent fill impacts to the Unnamed
Tributary to French Broad River).

Please give a couple of dates you are available for a meeting.

Duke Energy Progress, LLC (Duke Energy) is proposing to install a
remedial nonpermeable permanent cap (permanent cap) over coal
combustion residuals (CCR) used as structural fill at Area 1 of the
Asheville Regional Airport (ARA) in Buncombe County, North
Carolina. Area 1 is an 18-acre, CCR structural fill situated near the
northeastern ARA property boundary and was previously constructed
to expand airport operations. As -built drawings prepared by Charah
in 2010 indicate that Area 1 was constructed with a geosynthetic clay
liner (GCL) base liner and soil cap system. Soil backfill was
compacted on the GCL above and within 50 feet of the 60-in. RCP
that divides the Area 1 structural fill into western and eastern
components. The existing soil cap system was constructed with
approximately 6-ft and 2-ft thick soil layers on the top deck and side
slopes, respectively. In August 2019, NCDEQ requested that a
permanent cap system be designed to "abate the infiltration of
groundwater and/or precipitation into Area 1" and "to abate or control
...seepage water".
Duke Energy is proposing to construct a permanent cap for Area 1 to
comply with NCDEQ Solid Waste regulations for containment of CCR
and to achieve required stormwater runoff capture requirements
(Project). The proposed Project consists of a composite soil
geomembrane liner system designed to prevent and minimize surface
water infiltration into Area 1 structural fill, manage surface water, and
limit hydraulic head on the geomembrane. The proposed Project is
comprised of two components: 1) permanent non -permeable cap
layer system and 2) sediment and stormwater surface water ponds
(dry detention).
The permanent cap will be installed entirely within uplands and is
designed to shed surface water and to drain water infiltrated within
the cap to minimize potential ponding atop the geomembrane layer.
Stormwater drainage is designed to limit route length and will be
conveyed in three general directions off the cap: (i) east-northeast to
stormwater pond 1; (ii) west then northwest to stormwater pond 2;
and (iii) south to an existing stormwater channel towards Wright
Brothers Way.
Two existing sediment basins will be redeveloped and re -graded to
manage the construction and post -construction stormwater runoff
and sediment. The re -graded basins will also facilitate installation of
the permanent cap and achieve stormwater runoff capture
requirements. The surface water ponds are also designed as dry
ponds to release stormwater within 48 hours pursuant to Federal
Aviation Administration (FAA) regulations as not to attract nuisance
wildlife.
An existing underground stream (Unnamed Tributary to French Broad
River) daylights at the northwest toe of Area 1 and contributed to
erosion of the existing perimeter pond dike structure. As such, a rock
drain is proposed to convey the base stream flow beneath the pond;
while an outlet control structure and perimeter berm is proposed to
retain stormwater runoff prior to release into the existing stream.
The redevelopment and re -grading of the stormwater ponds will result
in approximately 0.56-acre of impacts to a non -tidal freshwater marsh
by stormwater pond and the installation of the outlet control structure
will result in 12 linear feet of permanent fill impacts to the Unnamed
Tributary to French Broad River).
