Asheville Regional Airport Expansion
Fletcher, North Carolina
CWS Project No. 2007-1889
The Asheville Regional Airport Expansion site is located adjacent to Interstate 26, on existing Airport
Authority property in Fletcher, North Carolina (Sheets 1 and 2, enclosed). The purpose of this project
is to develop approximately 33 acres into a mixed general aviation (GA) component for the airport
which will include hanger space, offices and opportunity for the transfer and transport of goods and
materials between groundside, at a four lane interstate highway, and airside, from the existing
commercial grade airstrip, to serve Buncombe County and the Asheville region. Secondarily, the
proposed fill at the facility will be fly ash produced as a byproduct from coal fired energy plants. The
fly ash will be placed on geo-textile material and will be covered by 24" of natural soil cap. The
current fly ash landfill is nearing capacity and it would need to expand or find a new facility in order
to accommodate this fly ash. With the airport placing the material, the existing landfill will be able to
gain approx. 8-10 years of storage capacity.

FEMA Floodplain
No portion of the project area or the proposed development is located within a FEMA regulated
floodplain (Sheet 6, enclosed), therefore no FEMA floodplain will be impacted by the project
activities.
Buncombe County Zoning
The existing site and proposed expansion are zoned for industrial use (Sheet 7, enclosed). No portion
of the site will be rezoned for the purpose of this project.
Jurisdictional Delineation
On June 13, 2007 CWS's Ron Johnson, PWS, Matt Jenkins, WPIT, Paul Bright, and Anthony Nardo
delineated (flagged in the field) and classified on-site jurisdictional waters of the U.S. using the U.S.
Army Corps of Engineers (USACE) - Routine On-Site Determination Method. Jurisdictional waters
of the U.S. were classified according to recent North Carolina Division of Water Quality (NCDWQ)2
and USACE guidance. NCDWQ Stream Classification Forms and USACE Stream Quality
Assessment Worksheets representative of Streams A - C are enclosed (SCP 1 - SCP5). On-Site
waters were determined to be jurisdictional according to the EPA/USACE Approved Jurisdictional
Determination Forms.
The results of the on-site field investigation indicate that there are three jurisdictional stream channels
Streams A - C) and three jurisdictional wetland areas (Wetlands AA - CC) located within the project
area (Sheet 8, enclosed). Routine On-Site Data Forms representative of Wetlands AA - CC as well as
non jurisdictional upland areas have been enclosed (DP 1 - DP4). On-Site jurisdictional waters of the
U.S. include unnamed tributaries to French Broad River. French Broad River is within the Upper
French Broad basin (HU# 06010105)
3 and is classified as "B;Tr" waters by the NCDWQ. On-Site
jurisdictional waters of the U.S. were surveyed by CWS using a sub-meter GPS unit and total
approximately 0.465 acre (20,255 square feet). Linear footage and acreage of on-site jurisdictional
waters are summarized in Table 1.

Agency Correspondence
Cultural Resources
A letter was forwarded to the State Historic Preservation Office (SHPO) on June 5, 2007 to determine
the presence of any areas of architectural, historic, or archaeological significance that would be
affected by the project. In a letter dated July 13, 2007, the SHPO stated that there "are no known
recorded archaeological sites within the project boundaries" (enclosed).
Protected Species
A letter was forwarded to the North Carolina Natural Heritage Program (NCNHP) on
June 5, 2007 to determine the presence of any federally-listed, candidate endangered, threatened
species or critical habitat located within the project area. In a letter dated June 13, 2007, the NCNHP
stated there "is no record of rare species, significant natural communities, or significant natural
heritage areas at the site, nor within 1/z mile of the project area" (enclosed).
Protected Species
A protected species survey was conducted to determine the potential for the occurrence of animal and
plant species formally proposed or listed as endangered or threatened by current Federal regulations
Federal Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.)] within the proposed project area.
The review consisted of a literature and records search, and a pedestrian survey performed by CWS's
Matt Jenkins, WPIT, and Paul Bright. CWS consulted the North Carolina Natural Heritage Program's
NCNHP) Natural Element Occurrence Search Page for Buncombe Countyl5l. The data contained in
this database was last updated March 1, 2007. According to the NCNHP database, there are four
Federally Endangered or Threatened species listed for Buncombe County. The Endangered species
for Buncombe County are the Carolina northern flying squirrel (Glaucomys sabrinus coloratus), gray
bat (Myotis grisescens), spreading avens (Geum radiatum) and the rock gnome lichen (Gymnoderma
lineare).
Plant species observed during the pedestrian survey were identified to species or to the lowest
taxonomic level necessary to determine if the observed specimen was a protected species. Plant
species identified in this report follow taxonomy described by Radford, et a1.161 The following section
describes the potential on-site habitats.
On-Site Habitat
The proposed project area is comprised of cleared mixed hardwood forest and old successional field,
Sheet 4, enclosed). Dominant vegetation within the mixed hardwood canopy includes red maple
acer rubrum), black cherry (Prunus serotina), tuliptree (Liriodendron tulipifera), and white oak

Carolina Northern Flying Squirrel (Glaucomys sabrinus coloratus)
The Carolina northern flying squirrel is found primarily in the transition zone between coniferous and
northern hardwood forests. Both forest types are used for food collection, while the northern
hardwood forest is used for nesting. Individuals often occupy tree cavities and woodpecker holes, but
will also construct nests. Carolina northern flying squirrels are very rare and occur in isolated
communities in North Carolina and Tennessee. CWS did not observe any potential habitat during the
pedestrian survey and no Carolina northern flying squirrels were observed on the day of the field
investigation.
Gray Bat (Myotis grisescens)
The gray bat is a cave dweller found primarily in Arkansas, Missouri, Tennessee, and Alabama, with a
few colonies in adjacent states. They rely on different types of caves for hibernating and maternity.
The hibernation caves are generally cooler than the maternity caves. Male gray bats and non-
reproductive females form bachelor colonies that aren't as restrictive on their nesting sites. CWS did
not observe any potential habitat during the pedestrian survey and no gray bats were observed on the
day of the field investigation.

Spreading Avens (Geum radiatum)
Spreading avens is an endemic in the rose family that occupies high elevation cliffs, outcrops and
steep slopes that are exposed to full sun in western North Carolina and Tennessee. The habitat is
usually found next to red spruce dominated coniferous forests. They are threatened by trampling,
development and air pollution. CWS did not observe any potential habitat during the pedestrian
survey and no spreading avens were observed on the day of the field investigation.
Rock Gnome Lichen (Gymnoderma lineare)
The rock gnome lichen is part of the reindeer moss family and is found on rocks in areas of high
humidity. These sites can occur at either high elevation or in deep river gorges at lower elevations.
Threats to rock gnome lichen are development, air pollution, collection, and coniferous forest decline.
CWS did not observe any potential habitat during the pedestrian survey and no rock gnome lichens
were observed on the day of the field investigation.
Biological conclusion: Given the results of the literature search and initial field investigation, it is
unlikely that the proposed project will impact the Carolina northern flying squirrel, gray bat,
spreading avens or the rock gnome lichen or their potential habitats.
Purpose and Need for the Project
The north expansion of the Asheville Regional Airport will provide for the surface area improvements
necessary to accommodate ground side and air side general aviation (GA) purposes which have been
identified as essential to the growing economic demand of the region. The facility must have both
direct access to commercial airstrip and ground side access to four lane interstate. Additionally, the
project will provide an alternate disposal site for the placement of fly ash byproduct from energy
producing coal fired power plants. The current fly ash landfill is nearing capacity and it would need
to expand or find a new facility in order to accommodate this fly ash. With the airport placing the
material, the existing landfill will be able to gain approx. 8-10 years of storage capacity.
The Asheville Regional Airport has a need to expand its development to meet the increased demand in
the aviation industry. Due to the limited real estate for aviation use with access to both taxiway and
runway facilities, and the boundary of the French Broad River, Interstate 26, and NC Route 280, this
area is the airports most economically feasible land to develop for aviation use. This project will
satisfy a portion of the publicly approved 20 year master plan for the airport. It is the purpose of this
project to provide service to economic development needs of Asheville Region and Buncombe County
by providing airside access to airstrip and groundside access to four lane interstate with approximately
450,000 square feet of new ramp, apron and taxiway; approximately 200,000 new square feet of
building and approximately 150,000 new square feet of roadway and parking. The project has been
designed to satisfy the safety concerns of the FAA. This site is intended for disposal of fly ash as
alternative to utilizing valuable landfill space. State permits have already been obtained for placement
of fly ash.
Avoidance and Minimization
The expansion of the existing airport development to the north occurs on a site which is bisected by a
perennial stream. Development to one side or the other of the stream would not yield sufficient
development area to satisfy the project purpose and need. The stream cannot be relocated to the east
due to shallow bedrock to the ground surface and topographic constraints. The stream cannot be

relocated to the west due to FAA restrictions on open water and forested buffers adjacent to runways
due to safety issues.
Minimization of impacts to downstream aquatic resources will be accomplished by filling the area so
that grade directs stormwater flows away from surface waters and into off-line stormwater BMP
treatment measures.
Alternatives Analysis
The ARV has reviewed alternatives for the development of the expansion area including the
following:
Alternative 1 - No Build Alternative
The No-Build Alternative will result in no impacts to jurisdictional streams or wetlands but does not
satisfy project purpose and need to provide airside access to airstrip and groundside access to four
lane interstate with approximately 450,000 square feet of new ramp, apron and taxiway;
approximately 200,000 new square feet of building and approximately 150,000 new square feet of
roadway and parking. This alternative does not provide for disposal of fly ash as alternative to
utilizing valuable landfill space.
Alternative 2 - Off-Site Development Alternative
The Off-Site Development Alternative will result in no impacts to jurisdictional streams or wetlands
on this site but does not satisfy project purpose and need to provide airside access to airstrip and
groundside access to four lane interstate with approximately 450,000 square feet of new ramp, apron
and taxiway; approximately 200,000 new square feet of building and approximately 150,000 new
square feet of roadway and parking. This alternative does not provide for disposal of fly ash as
alternative to utilizing valuable landfill space.
Alternative 3 - West Side Development Alternative
The West Side Development Alternative will result in no impacts to jurisdictional streams or wetlands
but does not satisfy project purpose and need since it does not have direct access to four lane interstate
and terminal. This alternative does not provide for disposal of fly ash as alternative to utilizing
valuable landfill space.
Alternative 4 - South Side Development Alternative
The South Side Development Alternative will result in no impacts to jurisdictional streams or
wetlands but does not satisfy project purpose and need since it does not enough land area adjacent to
both airstrip and interstate to provide the necessary program elements. This alternative does not
provide for disposal of fly ash as alternative to utilizing valuable landfill space.
Alternative 5 - East Side Development Alternative
The East Side Development Alternative will result in no impacts to jurisdictional streams or wetlands
but does not satisfy project purpose and need since it is not adjacent to airstrip and does not enough
land area to provide the necessary program elements. This alternative does not provide for disposal of
fly ash as alternative to utilizing valuable landfill space.
Alternative 6 - Reduced Scope and Scale Alternative
The Reduced Scope and Scale Alternative will result in fewer impacts to jurisdictional streams or
wetlands but does not satisfy project purpose and need to provide airside access to airstrip and
groundside access to four lane interstate with approximately 450,000 square feet of new ramp, apron
and taxiway; approximately 200,000 new square feet of building and approximately 150,000 new
square feet of roadway and parking. Reducing the scope and scale would render the project not
economically feasible. This alternative provides less area for disposal of fly ash as alternative to
October 26, 2007
Ms. Loretta Beckwith
Page 8 of 9
utilizing valuable landfill space.
Alternative 7 - On-Site Northern Development Alternative (Preferred Alternative)
The On-Site Northern Development Alternative will result in unavoidable impacts to jurisdictional
streams or wetlands on this site but it does satisfy project purpose and need to provide airside access
to airstrip and groundside access to four lane interstate with approximately 450,000 square feet of new
ramp, apron and taxiway; approximately 200,000 new square feet of building and approximately
150,000 new square feet of roadway and parking. This alternative does provide for disposal of fly ash
as alternative to utilizing valuable landfill space. Negative effects to downstream water quality and
important aquatic functions and values will be prevented through appropriate erosion and sediment
control methods during construction and the incorporation of permanent stormwater management
measures designed to remove Total Suspended Solids (TSS) before they reach downstream receiving
waters.
Proposed Impacts to Jurisdictional Waters
Unavoidable impacts to Perennial Streams will total approximately 1,640 linear feet and impacts to
wetland areas will total 0.209 acre (Sheets 10-14, enclosed). Impacts are due to grading activities
associated with the expansion of the Asheville Regional Airport North General Expansion Project.
The main drainage will be piped with 1,175 liner feet of 60" Reinforced Concrete Pipe (RCP). Fly
ash will be used to backfill the area. Progress Energy holds the non-site specific permit for the
disposal of the fly ash. The fly ash will be capped with a 24 inch top soil cap. A Typical Cross
Section has been included as Sheet 11. On behalf of The Asheville Regional Airport, CWS is
submitting a Section 404 Individual Permit Application with attachments (enclosed).
Compensatory Mitigation
Applicant proposes a donation to the NC Ecosystem Enhancement Program as mitigation for all
proposed impacts to streams and wetlands. The AVL is proposing a donation of $401,800 for impacts
to 1,640 linear feet of perennial stream at a 1:1 ratio. The AVL is proposing a $7,737.75 for impacts
to 0.25 acre of riparian wetland area at a 1:1 ratio. Total donation to the EEP will be $409,537.75. A
request has been forwarded to NCEEP to ensure the credits will be available.
Stormwater Management
A Stormwater Management Plan has been designed to minimize impacts to downstream aquatic
resources. The plan has been designed according to NC Division of Water Quality Standard. A copy
of the Post-Development Drainage Plan has been included as Sheets 15-17. Stormwater calculations to
justify the design have been included.

enter this area from the Airport Director.

18. Nature of Activity (Description of project, include ail features)
The Asheville Regional Airport has a need to expand its development to meet the increased demand in the aviation industry. Due to the limited real estate for aviation use
with access to both taxiway and runway facilities, and the boundary of the French Broad River, Interstate 26, and NC Route 280, this is the airports only remaining devel-
opable land for aviation use. This project will satisfy a portion of the publicly approved 20 year master plan for the airport. It is the purpose of this project to provide
service to economic development needs of Asheville Region and Buncombe County by providing airside access to airstrip and groundside access to four lane interstate
with approximately 450,000 square feet of new ramp, apron and taxiway; approximately 200,000 new square feet of building and approximately 150,000 new square feet
of roadway and parking. The project has been designed to satisfy the safety concerns of the FAA. This site is intended for disposal of fly ash as alternative to utilizing
valuable landfill space. State permits have already been obtained for placement of fly ash.
19. Project Purpose (Describe the reason or purpose of the project, see instructions)

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions,enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character

Boxes checked below shall be supported by completing the appropriate sections in Section III below.
Z For purposes of this form,an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least"seasonally"
(e.g.,typically 3 months).

SECTION III: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW,complete
Section III.A.1 and Section III.D.1.only;if the aquatic resource is a wetland adjacent to a TNW,complete Sections III.A.1 and 2

B. CHARACTERISTICS OF TRIBUTARY(THAT IS NOT A TNW)AND ITS ADJACENT WETLANDS(IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands,if any,and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are"relatively permanent
waters"(RPWs),i.e.tributaries that typically flow year-round or have continuous flow at least seasonally(e.g.,typically 3
months).A wetland that directly abuts an RPW is also jurisdictional.If the aquatic resource is not a TNW,but has year-round
(perennial)flow,skip to Section HI.D.2.If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section HI.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation.Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial(and its adjacent wetlands if any)and a traditional navigable water,even
though a significant nexus finding is not required as a matter of law.
If the waterbody°is not an RPW,or a wetland directly abutting an RPW,a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW.If the tributary has adjacent wetlands,the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands.This significant nexus evaluation that combines,for
analytical purposes,the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary,or its adjacent wetlands,or both.If the JD covers a tributary with adjacent wetlands,complete Section III.B.1 for
the tributary,Section HI.B.2 for any onsite wetlands,and Section HI.B.3 for all wetlands adjacent to that tributary,both onsite
and offsite.The determination whether a significant nexus exists is determined in Section IH.0 below.
1. Characteristics of non-TNWs that flow directly or indirectly into TNW
(i) General Area Conditions:
Watershed size: 1,196,80
Drainage area: 1.68
Average annual rainfall:38.1 inches

C. SIGNIFICANT NEXUS DETERMINATION
A Significant nexus aaaivsis�Y iii assess �Ae ilo%v c}iaracteristics and 1nnctions of the Eributar-; itself aim -he i'uacdons performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical,physical,and biological integrity
of a TNW. For each of the following situations,a significant nexus exists if the tributary,in combination with all of its adjacent
wetlands,has more than a speculative or insubstantial effect on the chemical,physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include,but are not limited to the volume,duration,and frequency of the flow
of water in the tributary and its proximity to a TNW,and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance(e.g.between a
tributary and its adjacent wetland or between a tributary and the TNW).Similarly,the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW,as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook.Factors to consider include,for example:
• Does the tributary,in combination with its adjacent wetlands(if any),have the capacity to carry pollutants or flood waters to
TNWs,or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary,in combination with its adjacent wetlands(if any),provide habitat and lifecycle support functions for fish and
other species,such as feeding,nesting,spawning,or rearing young for species that are present in the TNW?
• Does the tributary,in combination with its adjacent wetlands(if any),have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary,in combination with its adjacent wetlands(if any),have other relationships to the physical,chemical,or
biological integrity of the TNW?
Note:the above list of considerations is not inclusive and other functions observed or known to occur should be documented

B. CHARACTERISTICS OF TRIBUTARY(THAT IS NOT A TNW)AND ITS ADJACENT WETLANDS(IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands,if any,and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are"relatively permanent
waters"(RPWs),i.e.tributaries that typically flow year-round or have continuous flow at least seasonally(e.g.,typically 3
months).A wetland that directly abuts an RPW is also jurisdictional.If the aquatic resource is not a TNW,but has year-round
(perennial)flow,skip to Section IH.D.2.If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section IH.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation.Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial(and its adjacent wetlands if any)and a traditional navigable water,even
though a significant nexus fmding is not required as a matter of law.
If the waterbody4 is not an RPW,or a wetland directly abutting an RPW,a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW.If the tributary has adjacent wetlands,the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands.This significant nexus evaluation that combines,for
analytical purposes,the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary,or its adjacent wetlands,or both.If the JD covers a tributary with adjacent wetlands,complete Section HLBA for
the tributary,Section III.B.2 for any onsite wetlands,and Section HI.B.3 for all wetlands adjacent to that tributary,both onsite
and offsite.The determination whether a significant nexus exists is determined in Section I LC below.

C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical,physical,and biological integrity
of a TNW. For each of the following situations,a significant nexus exists if the tributary,in combination with all of its adjacent
wetlands,has more than a speculative or insubstantial effect on the chemical,physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include,but are not limited to the volume,duration,and frequency of the flow
of water in the tributary and its proximity to a TNW,and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance(e.g.between a
tributary and its adjacent wetland or between a tributary and the TNW).Similarly,the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW,as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook.Factors to consider include,for example:

B. CHARACTERISTICS OF TRIBUTARY(THAT IS NOT A TNW)AND ITS ADJACENT WETLANDS(IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands,if any,and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are"relatively permanent
waters"(RPWs),i.e.tributaries that typically flow year-round or have continuous flow at least seasonally(e.g.,typically 3
months).A wetland that directly abuts an RPW is also jurisdictional.If the aquatic resource is not a TNW,but has year-round
(perennial)flow,skip to Section IH.D.2.If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation.Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial(and its adjacent wetlands if any)and a traditional navigable water,even
though a significant nexus finding is not required as a matter of law.
If the waterbody°is not an RPW,or a wetland directly abutting an RPW,a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW.If the tributary has adjacent wetlands,the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands.This significant nexus evaluation that combines,for
analytical purposes,the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary,or its adjacent wetlands,or both.If the JD covers a tributary with adjacent wetlands,complete Section III.B.1 for
the tributary,Section III.B.2 for any onsite wetlands,and Section III.B.3 for all wetlands adjacent to that tributary,both onsite
and offsite.The determination whether a significant nexus exists is determined in Section HLC below.

the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime(e.g.,flow over a rock outcrop or through a culvert),the agencies will look for indicators of flow above and below the break.

C. SIGNIFICANT NEXUS DETERMINATION
"nif'canr ne pus 3iiaivsis %oil assess ale ;low marac2enstics and functions of zhe tribmarV itself and :he functions performed
by anv wetlands adjacent to the tributary to determine if they significantly affect the chemical,physical,and biological integrity
of a TNW. For each of the following situations,a significant nexus exists if the tributary,in combination with all of its adjacent
wetlands,has more than a speculative or insubstantial effect on the chemical,physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include,but are not limited to the volume,duration,and frequency of the flow
of water in the tributary and its proximity to a TNW,and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance(e.g.between a
tributary and its adjacent wetland or between a tributary and the TNW).Similarly,the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW,as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook.Factors to consider include,for example:
• Does the tributary,in combination with its adjacent wetlands(if any),have the capacity to carry pollutants or flood waters to
TNWs,or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary,in combination with its adjacent wetlands(if any),provide habitat and lifecycle support functions for fish and
other species,such as feeding,nesting,spawning,or rearing young for species that are present in the TNW?
• Does the tributary,in combination with its adjacent wetlands(if any),have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary,in combination with its adjacent wetlands(if any),have other relationships to the physical,chemical,or
biological integrity of the TNW?

B. CHARACTERISTICS OF TRIBUTARY(THAT IS NOT A TNW)AND ITS ADJACENT WETLANDS(IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands,if any,and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are`relatively permanent
waters"(RPWs),i.e.tributaries that typically flow year-round or have continuous flow at least seasonally(e.g.,typically 3
months).A wetland that directly abuts an RPW is also jurisdictional.If the aquatic resource is not a TNW,but has year-round
(perennial)flow,skip to Section IH.D.2.If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation.Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial(and its adjacent wetlands if any)and a traditional navigable water,even
though a significant nexus finding is not required as a matter of law.
If the waterbody°is not an RPW,or a wetland directly abutting an RPW,a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW.If the tributary has adjacent wetlands,the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands.This significant nexus evaluation that combines,for
analytical purposes,the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary,or its adjacent wetlands,or both.If the JD covers a tributary with adjacent wetlands,complete Section IH.B.1 for
the tributary,Section III.B.2 for any onsite wetlands,and Section III.13.3 for all wetlands adjacent to that tributary,both onsite
and offsite.The determination whether a significant nexus exists is determined in Section IH.0 below.

the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime(e.g.,flow over a rock outcrop or through a culvert),the agencies will look for indicators of flow above and below the break.

C. SIGNIFICANT NEXUS DETERMINATION
sigai#'icanr nexus aaa,vsis will assess the;low characterisdcs and functions W :he lribatar-. itself and the fuacdoas oeriormed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical,physical,and biological integrity
of a TNW. For each of the following situations,a significant nexus exists if the tributary,in combination with all of its adjacent
wetlands,has more than a speculative or insubstantial effect on the chemical,physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include,but are not limited to the volume,duration,and frequency of the flow
of water in the tributary and its proximity to a TNW,and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance(e.g.between a
tributary and its adjacent wetland or between a tributary and the TNW).Similarly,the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW,as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook.Factors to consider include,for example:
• Does the tributary,in combination with its adjacent wetlands(if any),have the capacity to carry pollutants or flood waters to
TNWs,or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary,in combination with its adjacent wetlands(if any),provide habitat and lifecycle support functions for fish and
other species,such as feeding,nesting,spawning,or rearing young for species that are present in the TNW?
• Does the tributary,in combination with its adjacent wetlands(if any),have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary,in combination with its adjacent wetlands(if any),have other relationships to the physical,chemical,or
biological integrity of the TNW?
Note:the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below,based on the tributary itself,then go to Section III.D:
2. Significant nexus findings for non-RPW and its adjacent wetlands,where the non-RPW flows directly or indirectly into

B. CHARACTERISTICS OF TRIBUTARY(THAT IS NOT A TNW)AND ITS ADJACENT WETLANDS(IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands,if any,and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are"relatively permanent
waters"(RPWs),i.e.tributaries that typically flow year-round or have continuous flow at least seasonally(e.g.,typically 3
months).A wetland that directly abuts an RPW is also jurisdictional.If the aquatic resource is not a TNW,but has year-round
(perennial)flow,skip to Section IH.D.2.If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section HI.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation.Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial(and its adjacent wetlands if any)and a traditional navigable water,even
though a significant nexus finding is not required as a matter of law.
If the waterbody4 is not an RPW,or a wetland directly abutting an RPW,a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW.If the tributary has adjacent wetlands,the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands.This significant nexus evaluation that combines,for
analytical purposes,the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary,or its adjacent wetlands,or both.If the JD covers a tributary with adjacent wetlands,complete Section HLBA for
the tributary,Section HI.B.2 for any onsite wetlands,and Section IH.B3 for all wetlands adjacent to that tributary,both onsite
and offsite.The determination whether a significant nexus exists is determined in Section IH.0 below.

Summarize overall biological,chemical and physical functions being performed:
C. SIGNIFICANT NEXUS DETERMINATION
A significant ilesaas ana'rsis;vaii assess tine fiow characteristics and functions of the iributar•:itself and the functions performed
by anv wetlands adjacent to the tributary to determine if then significantly affect the chemical, physical,and biological integrity
of a TNW. For each of the following situations,a significant nexus exists if the tributary,in combination with all of its adjacent
wetlands,has more than a speculative or insubstantial effect on the chemical,physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include,but are not limited to the volume,duration,and frequency of the flow
of water in the tributary and its proximity to a TNW,and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance(e.g.between a
tributary and its adjacent wetland or between a tributary and the TNW).Similarly,the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW,as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook.Factors to consider include,for example:
• Does the tributary,in combination with its adjacent wetlands(if any),have the capacity to carry pollutants or flood waters to
TNWs,or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary,in combination with its adjacent wetlands(if any),provide habitat and lifecycle support functions for fish and
other species,such as feeding,nesting,spawning,or rearing young for species that are present in the TNW?
• Does the tributary,in combination with its adjacent wetlands(if any),have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary,in combination with its adjacent wetlands(if any),have other relationships to the physical,chemical,or
biological integrity of the TNW?
Note:the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below,based on the tributary itself,then go to Section III.D:
2. Significant nexus findings for non-RPW and its adjacent wetlands,where the non-RPW flows directly or indirectly into
TNWs. Explain findings of presence or absence of significant nexus below,based on the tributary in combination with all of its
adjacent wetlands,then go to Section III.D:
3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW.Explain findings of
presence or absence of significant nexus below,based on the tributary in combination with all of its adjacent wetlands,then go to
Section III.D:

Dear Mr. Nardo:
The Natural Heritage Program has no current record of rare species, significant natural communities, or
significant natural heritage areas at the site nor within 1/2-mile of the project area. [There are historic
records of rare aquatic species in the French Broad River, within one mile.]
You may wish to check the Natural Heritage Program database website at www.ncnhp.org for a listing of
rare plants and animals and significant natural communities in the county and on the quad map.
NC OneMap now provides digital Natural Heritage data online for free. This service provides site
specific information on G1S layers with Natural Heritage Program rare species occurrences and
Significant Natural Heritage Areas. The NC OneMap website provides Element Occurrence(EO)ID
numbers(instead of species name), and the data user is then encouraged to contact the Natural Heritage
Program for detailed information. This service allows the user to quickly and efficiently get site specific
NHP data without visiting the NHP workroom or w;iting for the Information Request to be answered by
NHP staff. For more information about data formats and access, visit<www.nconemap.com/data.html>,

Dear Mr. Nardo and Ms. Hughes:
Thank you for your letter of June 5, 2007, concerning the above project.
There are no known recorded archaeological sites within the project boundaries. However, the project area
has never been systematically surveyed to determine the location or significance of archaeological resources.
Based on the topographic and hydrological situation, there is a high probability for the presence of prehistoric
or historic archaeological sites.
We recommend that a comprehensive survey be conducted by an experienced archaeologist to identify and
evaluate the significance of archaeological remains that may be damaged or destroyed by the proposed
project. Potential effects on unknown resources must be assessed prior to the initiation of construction
activities.
Two copies of the resulting archaeological. survey report, as well as one copy of the appropriate site forms,
should be forwarded to us for review and comment as soon as they are available and well in advance of any
construction activities.
A list of archaeological consultants who have conducted or expressed an interest in contract work in North
Carolina is available at www.arch.dcr.state.nc.us/consults.htm. The archaeologists listed, or any other
experienced archaeologist, may be contacted to conduct the recommended survey.
The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the
Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR
Part 800.

development. Clearly, Asheville Regional plays a major role in our regional economy and the
additional business envisioned for the northern sites will add to that positive economic impact.
I understand that you are in the midst of the permitting process and trust that will progress
smoothly. If we can assist in some way, please feel free to call on me.
