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%2 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 County 15]. The data contained in 5 The NCNHP Element Occurrence Search Page,found online at http://207.4.179.50/nhp/county.litml,accessed on June 12,2007. May 1,2008 ® 0 Ms.Loretta Beckwith Page 5 of 10 this database was last updated March 1,2007. According to the NCNHP database,there are four Current 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). Bunched arrowhead(Sagittaria fasciculate) is listed as Historic in Buncombe County and was not observed within the site. The only potential habitat is Wetland CC which is located in a seep area with loamy soils. Bunched arrowhead requires seepage areas with very low water flow and no stagnation; soils are sandy loams overlain by muck 10-24 inches deep; some shade is beneficial. Wetland CC was heavily shaded and dominated by jewelweed and various sedges. No overlaying muck layer was observed in this wetland area. It is the opinion of CWS that Wetland CC is not a suitable habitat for bunched arrowhead. 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 (Quercus alba),. Understory vegetation within this area includes poison ivy(Toxicodendron radicans),American holly(Ilex opaca), cinnamon fern(Osmunda cinnamomea), green catbriar (Smilax rotundifolia), and black raspberry(Rubus occidentalis). Dominant vegetation within the early successional fields includes tuliptree(Liriodendron tulipifera),white oak(Quercus alba), green catbriar(Smilax rotundifolia),black raspberry(Rubus occidentalis),Aster(Aster spp.)and various grasses(Festuca spp.).

PD Proposed De-listed A taxon that is proposed for de-listing FSC Federal Species of A species under consideration for listing,for which there is Concern insufficient information to support listing at this time 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. Grav 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. Bunched arrowhead(Sagittaria fasciculate)is listed as Historic in Buncombe County and was not observed within the site. The only potential habitat is Wetland CC which is located in a seep area with loamy soils. Bunched arrowhead requires seepage areas with very low water flow and no May 1, 2008 Ms. Loretta Beckwith Page 7 of 10 stagnation; soils are sandy loams overlain by muck 10-24 inches deep; some shade is beneficial. Wetland CC was heavily shaded and dominated by jewelweed and various sedges. No overlaying muck layer was observed in this wetland area. It is the opinion of CWS that Wetland CC is not a suitable habitat for bunched arrowhead. Purpose and Deed 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. 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. 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. 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 would also require land acquisition by the airport. Alternative 3 —West Side Development Alternative The West Side Development Alternative will result in impacts to 2,371 linear feet of jurisdictional streams and also does not satisfy project purpose and need since it does not have access to four lane interstate and terminal. The USGS topographic map shows a"blue line"stream in this location. This area doesn't have existing support infrastructure(access,utilities,taxiways, aprons, etc). In order to access the airport terminal from this area, all traffic will need to cross the runway which will cause safety issues and could delay flights. Alternative 4—South Side Development Alternative May 1,2008 Ms. Loretta Beckwith Page 8 of 10 The South Side Development Alternative will result in impacts to approximately 2,818 linear feet of jurisdictional streams 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 cannot be adjacent to Runway/Taxiway system due to Rental car Facility. The elevation of this piece of land is 30 feet lower than the existing development and it cannot be filled due to the location of the rental car facility. Alternative 5—East Side Development Alternative The East Side Development Alternative will impact jurisdictional streams or wetlands but does not satisfy project purpose and need since it is not adjacent to airstrip and does not have enough land area to provide the necessary program elements. This alternative is located across NC-280 and will have no access to Runway/Taxiway System unless a taxiway bridge is built to span the highway. A bridge of this nature would not be cost effective for this project. In addition,the land area geometry and size is not adequate for the development. 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. 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 will provide access to I-26 via NC- 280(Sheet X, enclosed). This alternative is consistent with FAA approved Master Plan and Land Use Plan Alternative 8—An additional alternative suggested by the NCDWQ was to relocate the stream to the east side of the development. The topography of the site will not allow a proper relocation of the stream due to the drastic elevation change across the site. 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. Impacts were reduced for the Preferred Alternative by reducing the fill slopes from 4:1 to 3:1 on the north end of the development. A retaining wall and wing walls were added to the north outlet of the 60"RCP to further reduce impacts. The use of the rip rap apron was avoided through the use of an internal energy dissipater to the pipe. The system was designed with an O-Ring Gasket RCP pipe to seal out ground water from the pipe. This minimization strategy has reduced stream impacts by 441 linear feet and wetland impacts by 0.158 acre from the original proposed activities. Minimization of May 1, 2008 Ms. Loretta Beckwith Page 9 of 10 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. 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 storm water 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 1,535 linear feet and impacts to wetland areas will total 0.359 acre(Sheets 10-14, enclosed). Approximately 138 linear feet(0.008 acre) of Unimportant Intermittent Stream will be impacted. 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. Details for the liner installation have been included. The groundwater will be monitored using wells. Details of the monitoring well installation and monitoring plan are enclosed. 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 The existing culvert downstream of the site will be removed and restored back to a natural stream channel. The restoration will include enhancements to the downstream 50 linear feet of channel. Mitigation for the pipe removal will be accomplished by removing the existing pipe and grading the channel to match the existing banks. The newly graded banks will be lined with erosion control matting and planted with live stakes. Live stakes will be harvested locally and will be native vegetation. Only healthy,well branched, and disease free species shall be used. Following the first growing season the live stakes shall be monitored to ensure an 85 % survival rate. If the 85% survival rate is not achieved the client will re-plant the live stakes to ensure this survival rate. A conceptual design will be submitted under separate cover. Applicant proposes a donation to the NC Ecosystem Enhancement Program as mitigation for all proposed impacts to streams and wetlands minus the 150 linear foot restoration. The AVL is proposing a donation of$678,650 for impacts to 1,385 linear feet of perennial stream at a 2:1 ratio. The AVL is proposing a$29,351 for impacts to 0.50 acre of riparian wetland area at a 2:1 ratio. Total donation to the EEP will be$708,001. A revised 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. 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 storm water management measures designed to remove Total Suspended Solids(TSS)before they reach downstream receiving waters. 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. A Stormwater Pollution Prevention Plan(SPPP)template is being developed for the North Carolina Airport Association(NCAA)that will provide guidance on best management practices(BMPs)that May 1, 2008 Ms.Loretta Beckwith Page 10 of 10 should be followed by NCAA-member airports to prevent or reduce stormwater pollution from their industrial activities. As such,Asheville Regional Airport will implement BMPs, including fuel disposal barrels and ramp sweeping activities for the General Aviation Apron Area to help treat stormwater runoff from the existing impervious areas. Please do not hesitate to contact me at 704-527-1177 or through email at craig@cws-inc.net should you have any questions or comments regarding these findings.

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 of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more continuity,and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100,with a score of 100 representing a stream of the highest quality.

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 M.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 waterb'ody4 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 II1.13.2 for any onsite wetlands,'ana Section III:B:31or 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.

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?

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 III.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 III.B.1 for the tributary,Section 11I.B.2 for onsite wetlands,-and Section 1H.B.3-for all wetlands adjacent to that tributary,both onsite and offsite.The determination whether a significant nexus exists is determined in Section III.0 below. 1.

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: • 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.

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 III.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"riot 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 I.B'.2 for any onsite wetlands,and Section III.B.3 for all wetlands adj"acent to-that tributary,both onsite and offsite.The determination whether a significant nexus exists is determined in Section III.0 below. 1.

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,slip to Section III.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 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 IH.B.1 for the tributary,Section III.B.2 for any onsite wetlands;and Section M.B.3-"for all wetlands adjacent to that tributary,both onsite " and offsite.The determination whether a significant nexus exists is determined in Section III.0 below. 1.

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 III.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 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 III.B.1 for the tributary,Section III.B.2 for any onsite wetlands,and Section M.-R3 for all wetlands adjacent to that tributary,-both and offsite.The determination whether a significant nexus exists is determined in Section III.0 below. 1.

SIGNIFICANT NEXUS DETERMINATION .-�3-niiicanc ae:Y'!]s allai,sis-will assess die flow dharacz'erisdcs and fnnctions 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 floodpWn 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: `L Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs.

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 III.B.1 for - the tributary,Section III.B.2 for any onsite wetlands;and Section IH.B.3 for all wetlands adjacent to that tributary,both onsite and offsite.The determination whether a significant nexus exists is determined in Section HI.0 below. 1.

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:- • 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?

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 M.D.I.only;if the aquatic resource is a wetland adjacent to a TNW,complete Sections III.A.1 and 2 and Section III.D.1.; otherwise,see Section II1.13 below. 1.

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 HI.B.1 for -the-tributary,Section III.B.2 for any onsite wetlands,and Section 11I.13.3 for all wetlands adjacent to that tributary,both onsite and offsite.The determination whether a significant nexus exists is determined in Section III.0 below. 1.

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: • 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?

TNWs: linear feet width(ft),Or, acres. Wetlands adjacent to TNWs: acres. 2. RPWs that flow directly or indirectly into TNWs. Tributaries of TNWs where tributaries typically flow year-round are jurisdictional.Provide data and rationale indicating that tributary is perennial: } Tributaries of TNW where tributaries have continuous flow"seasonally"(e.g.,typically three months each year)are jurisdictional. Data supporting this conclusion is provided at Section III.B. Provide rationale indicating that tributary flows seasonally: Stream D flows north for approximately 46 linear feet until its confluence with Perennial Stream A(Figure 1, enclosed). This channel exhibited an average ordinary high water width of 1-2 feet,perennial flow,weak sinuosity,and substrate consisting of silt to large gravel. Intermittent Stream D scored 29 out of a possible 100 points on the USACE Stream Quality Assessment Form and 22.5 out of 71 possible points on the NCDWQ Stream Classification Form,indicating intermittent status(SCP6,enclosed).A Photograph of Stream D is enclosed as Photograph G.. Provide estimates for jurisdictional waters in the review area(check all that apply): Tributary waters:46 linear feetl-2width(ft). Other non-wetland waters: acres. Identify type(s)of waters: 3. Non-RPWss that flow directly or indirectly into TNWs. Waterbody that is not a TNW or an RPW,but flows directly or indirectly into a TNW,and it has a significant nexus with a TNW is jurisdictional.Data supporting this conclusion is provided at Section III.C. Provide estimates for jurisdictional waters within the review area(check all that apply): Tributary waters: linear feet width(ft). { Other non-wetland waters: acres. Identify type(s)of waters: 4. Wetlands directly abutting an RPW that flow directly or indirectly into TNWs. Wetlands directly abut RPW and thus are jurisdictional as adjacent wetlands. Wetlands directly abutting an RPW where tributaries typically flow year-round. Provide data and rationale indicating that tributary is perennial in Section III.D.2,above.Provide rationale indicating that wetland is directly abutting an RPW: Wetlands directly abutting an RPW where tributaries typically flow"seasonally." Provide data indicating that tributary is seasonal in Section II1.13 and rationale in Section III.D.2,above.Provide rationale indicating that wetland is directly abutting an RPW:Wetland DD is located at the upstream portion of Intermittent Stream D(Figure 1,enclosed). This herbacious wetland area is approximately 0.015 acre is size. Dominant vegetation within this area includes common rush (Juncus effuses),chinese privet(Ligustrum sinense);and various sedges(Carex spp.). This area exhibited low chroma soils(2.5Y 4/2)with mottles(7.5YR 5/6),inundation to 2 inches,drainage patterns,and saturation within the upper 12 inches of the soil profile. A Routine On-Site Determination Form representative of Wetland DD is enclosed(DP3). Photographs of Wetland FF are enclosed as Photographs K and L. A Routine On-Site Determination Form representative of on-site non jurisdictional upland areas is also enclosed(DP1). Provide acreage estimates for jurisdictional wetlands in the review area: 0.015acres. 5. Wetlands adjacent to but not directly abutting an RPW that flow directly or indirectly into TNWs. Wetlands that do not directly abut an RPW,but when considered in combination with the tributary to which they are adjacent and with similarly situated adjacent wetlands,have a significant nexus with a TNW are jurisidictional.Data supporting this conclusion is provided at Section III.C. Provide acreage estimates for jurisdictional wetlands in the review area: acres. 6. Wetlands adjacent to non-RPWs that flow directly or indirectly into TNWs. `f Wetlands adjacent to such waters,and have when considered in combination with the tributary to which they are adjacent and with similarly situated adjacent wetlands,have a significant nexus with a TNW are jurisdictional.Data supporting this conclusion is provided at Section III.C. Provide estimates for jurisdictional wetlands in the review area: acres. 7. Impoundments of jurisdictional waters. As a general rule,the impoundment of a jurisdictional tributary remains jurisdictional.

Nardo Andrea L. Hughes Carolina Wetland Services 650 E. Westinghouse Blvd. Charlotten,NC 28273 Re: Asheville Regional Airport, Fletcher, Buncombe County,ER 07-1252 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 w,vw.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.

Requested answers for response Dear Kevin, Liner IbMonitorina: Attached,please find the reports detailing the Geosynthetic Clay Liner(GCL)installation, preformed by an independent consulting engineer. We will continue to inspect the liner installation accordingly as required:. Soil and Erasion Control: In case of breach, such that visible ash or sediment is leaving the disturbed limits of the site, corrective action shall be taken immediately to terminate further discharge. Additionally,the Division of Water Quality(DWQ)will be notified within.24 hours of discovery and a report documenting the corrective measures taken,will be submitted to DWQ within 15 days. At a Minimum,the source of the breach will be identified and repaired sufficient to avoid a future release. Following repair, the entire sediment control system will be evaluated to establish if the breach was an anomalous occurrence or if additional measures need to be taken to provide sufficient sediment control and protection of water quality. Additional measures could include; providing additional rows of silt fencing, sediment collection areas,better stabilization of existing controls, and/or more frequent inspections. Records of corrective measures,whether temporary or permanent,taken at the site will be maintained onsite and will be distributed to DWQ. Ground water Monitoring: There have been four monitoring wells installed both up gradient and down gradient. Please see attached groundwater monitoring well location and ground water table data. We believe that the above measures provide suitable protection of the stream and wetlands downstream of the project and comply with requirements of the non-discharge permit. Charah will continue to monitor and report this water table data for five years following ash placement completion. We will work with the Aquifer Protection Section to provide whatever groundwater information as required.

From: Tim.Silar—Silar Services Incorporated Date: April 15, 2008 Subject: Hydrogeologic Assessment Status Report Charah Inc. (Charah) has requested that Silar Services Incorporated (SSi) conduct a hydrogeologic assessment to addresses requirements related to Permit Number WQ0000020 issued by the North Carolina Department of Environment and Natural Resources (NCDENR), specifically - evaluate seasonal high water table as per section H. Operation and Maintenance Requirements, 9b. To accomplish this objective groundwater monitoring wells will be installed and initial water level data have been collected. These activities are summarized below. Monitoring Well Installation Four monitoring wells were installed in early January 2008 to provide groundwater elevation measuring points and thereby an understanding of groundwater conditions. The monitoring wells will be installed by a Geologic Exploration from Statesville, NC using hollow-stem auger and air rotary techniques and constructed in accordance with Federal and State guidelines. The location of the monitoring wells is illustrated on Figure 1. A summary of the monitoring wells construction is included in Table 1. Monitoring wells were screened across the water table (first water). Water Level Measurements Continuous water level measurements have been collected from monitoring wells MW-1 and MW-2 to gain requisite data to access the seasonal high water elevation. Measure are collected with in well pressure transducer at a frequency of one reading every ten minutes. A summary of water level elevation from MW-1 from January 4 to March 4, 2008 are included in Figure 2. This data indicated that the groundwater water elevation has fluctuated in a narrow range from approximately 2,087.3' to 2,088.7' above mean sea level (MSL). Summary Four monitoring wells were installed to evaluate groundwater elevation in the project area. Water levels collected to data indicates that groundwater elevations fluctuate in a narrow range with a maximum groundwater elevation of less than 2,089' MSL.

U.S. Fish and Wildlife Service(USFWS) The USFWS expressed the following concerns: (1) Some wetlands and seeps in the project area were not included in the public notice. (2) That the site had been cleared, to include the wetland areas. (3) There is a lack of information about the alternatives analysis. (4) Concern about the stormwater system. (5)The agency offered the following recommendations to help address the impacts associated with this project and to help minimize impacts to fish and wildlife resources: 1. Reduce road width, use grassed swales in place of curb and gutter, and implement on-site storm-water-management measures (i.e., bioretention areas, rain gardens, and constructed wetlands) that will result in no net change in the hydrology of the watershed.As previously stated, without proper planning, this development will create impervious surfaces (such as roofs, roads, and parking lots) that will collect pathogens, metals, sediment, and chemical pollutants and quickly transmit them to receiving waters. Therefore, all storm-water outlets should drain through a vegetated upland area prior to reaching any stream or wetland area. Sufficient retention designs should be implemented to allow for the slow discharge of stormwater, attenuating the potential adverse effects of storm-water surges; thermal spikes; and sediment, nutrient, and chemical discharges. 2. Minimize the amount of impervious surface area that will occur as a result of this project. We recommend that all parking areas and taxiways be constructed of a pervious material(ie. pervious concrete, interlocking/open paving blocks, etc.), Pervious materials are less likely to absorb and store heat and allow the cooler temperatures of the earth be to cool the pavement. Pervious concrete also requires less maintenance and is less susceptible to freeze/thaw cracking due to large void spaces within the concrete. Pervious parking areas minimize changes to the hydrology of the watershed can be used to facilitate groundwater recharge, and often eliminate the need for curb and gutter for drainage. 3. Install and maintain stringent measures to control erosion and sediment in order to prevent unnecessary impacts to aquatic resources within and downstream of the project site. Disturbed areas should be reseeded with seed mixtures that are beneficial to wildlife. Fescue- NORTH CAROLINA • SOUTH CAROLINA ° NEW YORK WWW.CWS-INC.NET May 1,2008 Ms. Loretta Beckwith Page 2 of 8 based mixtures should be avoided Native annual small grains appropriate for the season are preferred and recommended.Also,perimeter erosion-control devices should be installed prior to any on-the-ground activities. Frequent maintenance of these devices is critical to their proper function in order to minimize sediment discharge from the project site. 4. Implement low-impact-development designs into the project plans. We recommend that a rooftop garden, or a "green"rooftop, design be incorporated into the building construction plans for the multiuse development. Green rooftops have many benefits, including: (a) keeping buildings warmer by adding a layer of insulation to the roof and keeping buildings cooler by allowing plants to take in water that evaporates into the atmosphere, resulting in lower beating and cooling bills; (b) reducing the amount and improving the quality of storm- water runoff because water is absorbed and filtered through plants and soil; and(c) improving overall air quality by removing particulate matter from the air. This, along with the proposed storm-water runoff collection devices that will be constructed, will dramatically decrease the amount and increase the quality of stormwater runoff. (6) The project may have contained potential habitat for bunched arrowhead, which is federally listed as endangered and has been found in close proximity to the project area, and that surveys for listed species had not been conducted prior to site clearing activities. (7) The agency recommended that full restoration of the 0.172 acre wetland in the northern section of the project area be required, and would like to review the restoration plan. (8) Minimum of 3:1 ratio for mitigation for streams and wetlands. Response: (1) On March 12, 2008, a site visit was conducted by Carolina Wetlands,USACE and NCDWQ. All wetland delineation areas were revisited and a new Wetland Boundary Survey is attached. The text of the permit application has been revised to include these new areas. (2) Clearing and Grubbing was to be performed outside of all wetland areas and a fifty(50)foot stream buffer. Unfortunately,the contractor performing the work did not communicate effectively with a new foreman on the job site which resulted in the clearing of wetland area CC. This area will be restored if possible.The USACE and DWQ have requested that the pipe of the main tributary should be extended through the entire site. If this activity is required,then the restoration of Wetland CC is not possible. (3) Alternatives Avoidance 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 ound surface and too a hic constraints. The stream cannot e re ocated to the west due to FAA restrictions on open water an orested buffers adjacent to runways due to safety issues. Minimization Impacts were reduced for the Preferred Alternative by reducing the fill slopes from 4:1 to 3:1 on the north end of the development. A retaining wall and wing walls were added to the north outlet of the 60"RCP to further reduce impacts. The use of the rip rap apron was avoided through the use of an internal energy dissipater to the pipe. The energy dissipater will be in accordance with NC Erosion and Sedimentation Control Planning and Design Manual, Section 6.41.1. The system was designed r May 1,2008 Ms.Loretta Beckwith Page 3 of 8 with an O-Rin Gasket RCP pipe to seal out ground water fiom the pipe.

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 storm water management measures designed to remove Total Suspended Solids (TSS)before they reach downstream receiving waters. Minimization of impacts to downstream aquatic resources will be accomplished by filling the area so that grade directs storm water flows away from surface waters and into off-line storm water BMP treatment measures. A Stormwater Pollution Prevention Plan(SPPP)template is being developed for the North Carolina Airport Association(NCAA)that will provide guidance on best management practices (BMPs)that should be followed by NCAA-member airports to prevent or reduce stormwater pollution from their industrial activities. As such,Asheville Regional Airport will implement BMPs, including fuel disposal barrels and ramp sweeping activities for the General Aviation Apron Area to help treat stormwater runoff from the existing impervious areas. 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. 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 vgroundside 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 would also require land acquisition by the airport. Alternative 3 —West Side Development Alternative The West Side Development Alternative will result in impacts to 2,371 linear feet of jurisdictional streams and also does not satisfy project purpose and need since it does not have access to four lane interstate and terminal. The USGS topographic map shows a"blue line"stream in this location. This area doesn't have existing support infrastructure(access, utilities,taxiways, aprons, etc). In order to access the airport terminal from this area, all traffic will need to cross the runway which will cause safety issues and could delay flights. Alternative 4—South Side Development Alternative The South Side Development Alternative will result in impacts to approximately 2,818 linear feet of \ jurisdictional streams but does not satisfy project purpose and need since it does not enough land area v adjacent to both airstrip and interstate to provide the necessary program elements. This alternative cannot be adjacent to Runway/Taxiway system due to Rental car Facility. The elevation of this piece May 1,2008 Ms.Loretta Beckwith Page 4 of 8 of land is 30 feet lower than the existing development and it cannot be filled due to the location of the rental car facility. Alternative 5—East Side Development Alternative The East Side Development Alternative will impact jurisdictional streams or wetlands but does not satisfy project purpose and need since it is not adjacent to airstrip and does not have enough land area to provide the necessary program elements. This alternative is located across NC-280 and will have no access to Runway/Taxiway System unless a taxiway bridge is built to span the highway. A bridge of this nature would not be cost effective for this project. In addition,the land area geometry and size is not adequate for the development. 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. 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 will provide access to I-26 via NC- 280. This alternative is consistent with FAA approved Master Plan and Land Use Plan Alternative 8—An additional alternative suggested by the NCDWQ was to relocate the stream to the east side of the development. The topography of the site will not allow a proper relocation of the stream due to the drastic elevation change across the site. (4) Stormwater detention and treatment to be used was included in the 404 permit application. (5) 1)The airport is working with their engineer to look at the possibility of using grassed swales in lieu of curb and gutter on parking areas. As previously indicated in the original application submittal, all stormwater outlets for this development are run through a series of water quality devices prior to reaching any stream or wetland area. 2)Although pervious pavements can minimize the changes to the hydrology of the watershed, it also increases the potential of foreign object debris (FOD). FOD can be ingested into aircraft turbines causing engine damage or can be picked up in the aircraft jet blast causing injury to people and damage to property. FOD includes pieces of pavement,rocks and sand. 3)Erosion control measure shall be correctly install and maintained. Disturbed areas will be reseeded with a native seed that does not attract and increase in wildlife and jeopardize safety to the traveling pubic. 4)The majority of the proposed buildings for this project are aircraft hangar buildings and roof-top gardens are not practicable for this application. May 1,2008 Ms. Loretta Beckwith Page 5 of 8 (6) 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 1/2 mile of the project area" 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 perforined 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 County E51. The data contained in this database was last updated March 1,2007. According to the NCNHP database,there are four Current 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). Bunched arrowhead(Sagittaria fasciculate) is listed as Historic in Buncombe County and was not observed within the site. The only potential habitat is Wetland CC which is located in a seep area with loamy soils. Bunched arrowhead requires seepage areas with very low water flow and no stagnation; soils are sandy loams overlain by muck 10-24 inches deep; some shade is beneficial. Wetland CC was heavily shaded and dominated by jewelweed and various sedges. No overlaying muck layer was observed in this wetland area. It is the opinion of CWS that Wetland CC is not a suitable habitat for bunched arrowhead. (7) The avoided portions of Wetland CC will be restored. (8) The application has been revised to propose a 2:1 mitigation ratio. Revised credit requests have been forwarded to the NCEEP for acceptance. 2. The Eastern Band of Cherokee Indians Tribal Historic Preservation Office(EBCI TIIPO) The EBCI THPO stated that the projects location is within the aboriginal territory of the Cherokee People and that potential cultural resources important to the Cherokee people may be threatened due to adverse effects expected from the level of ground disturbance required for this project. The EBCI THPO would like to review all related archaeological, cultural resource and historical investigatory materials completed by the applicant. Response: A letter was forwarded to the State Historic Preservation Office(SHTO) 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". A copy of this letter will be forwarded to the EBCI THPO. 3. North Carolina Wildlife Resource Commission 5 The NCNHP Element Occurrence Search Page,found online at http://207.4.179.50/nhp/county.html,accessed on June 12,2007. 6 Radford,et al. 1968.Manual of the Vascular Flora of the Carolinas.The University of North Carolina Press,Chapel Hill,North Carolina. 1183 pp. May 1, 2008 Ms. Loretta Beckwith Page 6 of 8 The French Broad River near the airport supports a cool water fishery that includes smallmouth bass and muskellunge. Wetlands in this region are important to a variety of birds and other wildlife. Bog turtles (State Threatened) and mole and four-toed salamanders (State Special Concern) have been found in wetlands along the French Broad River within a few miles of the airport. The largest wetland on the preferred site probably supported salamanders before the site preparation occurred. It and the riparian areas on the property also were important for protecting water quality in the French Broad River. Given the important fish and wildlife resources in the area, the Commission is particularly concerned with the limited evaluation of project alternatives and the recent wetland and stream impacts that' have occurred on the preferred site. (1) One alternative discussed at the meeting, but dismissed in the application, involves using the preferred site by relocating a portion of stream channel A to the east instead of using this area solely for storm drainage swales. With this possibility, detained and treated storm water might be routed into the head of the open channel rather than near the property's northern boundary. Since the stream channel is now unstable and in generally poor condition, any project alternative that is pursued should address this situation. Another way to minimize impacts without changing the site development may be a slight shift and/or construction of a low retaining in the northeast fill slope, which currently necessitates filling wetland cc. However, this wetland would require restorative work like stream channel A given the disturbance that has occurred. Coal fly ash is not considered a hazardous waste, but it does contain trace elements that can be mobilized by water and cause toxicity to aquatic life. Therefore, if it is used as structural fill, then adherence to the requirements outlined in 15A NCAC 13B. 0.1700 will be particularly important because of proximity to water. These requirements include, in part, not placing ash within 50 feet of wetlands and streams, isolation of fill from storm water during filling, keeping fill slopes less than 3:1, and maintaining the fill area as a non-discharge structure. The separation requirement may not \ be met given the stream fill. Nevertheless, to keep the fill from discharging, an impervious fill base \\ and cover is recommended since the region normally receives considerable annual precipitation. Should non-discharge not be achieved, the Commission recommends that the discharge be periodically tested for toxic elements and, should standards be exceeded, a remediation plan executed in a timely manner. This would be similar to the monitoring that would be required to ensure compliance with groundwater standards (15A NCAC 2L). Extensive impervious cover from the proposed development has the potential to degrade downstream water quality. This is already evident on the preferred site where stream channel degradation appears to have increased following the site work and where petroleum and nutrient pollution was noted during the site visit. Therefore, the Commission requests that effective storm water detention and treatment be used for the expansion and any existing developed areas that can be incorporated. If impacts to the streams and wetlands on the preferred site are permitted, then a 2:1 or higher compensatory mitigation ratio is recommended. This recommendation is based on the apparently good condition of Wetland CC and the lower part of Stream A before site grading commenced and their regional importance to fish and wildlife resources. In addition, the function of streams and wetlands that will not be permanently filled, if applicable, should be restored. Response: (1) An additional alternative suggested by the NCWRC/NCDWQ was to relocate the stream to the east side of the development. This alternative was looked at and due to the drastic elevation change across the site;the topography of the site will not allow a proper relocation of the stream. May 1,2008 Ms. Loretta Beckwith Page 7 of 8 (2) As shown in the enclosed drawings,the creek and wetlands will be filled with clean fill material from nearby borrow areas or quarries (porous material discussed below). This fill will be of sufficient depth to cover by at least two feet the top of the pipe that will convey the relocated stream. As required in Condition 11. 9. of the non-discharge permit, approval will be obtained from the Aquifer Protection Section of the Asheville regional office for this design that protects the stream and groundwater with clean fill and a geosynthetic clay liner with a maximum hydraulic conductivity of 10,6 cm/sec. These measures, along with the containment of the stream within the pipe,justify waiver of the prohibition of ash placement within 50 feet of surface water, as allowed by the permit. There are no water supply wells or springs within 100 feet of the fill. The ash non-discharge permit requires the bottom of the ash fill to be a minimum of one foot above the seasonal high groundwater level. With regard to potential contact with groundwater,the project will have porous material in the former steam bed and under the reinforced concrete pipe to allow for drainage of groundwater from underneath the fill and therefore impede the groundwater table from reaching the bottom of the ash fill. As stated above,both the former stream bed and the reinforced concrete pipe will have a minimum of two feet of clean fill over them, and for an extra measure of protection, a geosynthetic clay liner over the clean fill and under any ash fill. When completed,the project will have a six feet thick compacted clean fill "cap" over it and it will then be mostly paved with an engineered drainage system to divert stormwater around the fill, so infiltration of water into the fill is expected to be minimal. The side slopes will have at least two feet of clean fill over the ash fill. We believe that the above measures provide suitable protection of the stream and wetlands downstream of the project and comply with requirements of the non-discharge permit. If the Division deems monitoring is necessary,there is an existing monitoring well both up gradient and down gradient. We will work with the Aquifer Protection Section to provide whatever groundwater monitoring is required. If necessary, samples may also be taken from the stream at appropriate locations both upstream and downstream of the activity after the project is completed. (3) Stormwater detention and treatment to be used was included in the 404 permit application. (4) The application has been revised to propose a 2:1 mitigation ratio. Revised credit requests have been forwarded to the NCEEP for acceptance. (5) The avoided portions of Wetland CC will be restored. 4.Adjacent Property Owner: James B. McKinney 16 Nathan Drive Arden, NC 28704 This is in response to the letter received December 1, 2007 in regards to the development of the Asheville Regional Airport location I reside at 16 Nathan Drive Arden, NC, which is adjacent to the area in question. My property line connects to the airports; therefore we receive a lot of water run off in to the small stream located under my driveway. With the run off from the Airport property into the small stream as caused my driveway to cave in a few years back See attached photos from the time that the driveway collapsed. We temporarily fixed the driveway until a few months ago, in which I installed a large concrete culvert&repaired the entire driveway. The cost of this project was around $2,500.00. I have contacted the airport authority in regards to this issue of water drainage before with no response. The airport has developed entirely around my property which has caused a lot of water drainage onto my property over the years. I believe the US Army Corps of Engineers may need r May 1, 2008 Ms. Loretta Beckwith Page 8 of 8 to investigate this a little further before signing off on it. Irealize that the airport has already begun movement of dirt and installation of the ashes product from Progress Energy. I just wonder if they have taken the proper safety precautions so that there will not be any water run off. If this development cause water drainage onto my property and causes the newly installed culvert to collapse again I feel that the airport authority should be responsible for the repairs. Response: The submitted stormwater collections system is intended to separate all new impervious and pervious development stormwater runoff from the existing airport stormwater system. This was to be accomplished through the extension of the existing 60"RCP storm drain outlet, allowing no addition flow. The airport will work with their engineer to add an energy dissipater at the down stream outlet of the 30"RCP. This will control the stormwater velocity before it leaves the airport property, minimizing the potential for erosion. Please do not hesitate to contact me at 704-527-1177 or through email at craig@cws-inc.net should you have any questions or comments regarding these findings. C +� Ron G.kcientist PWS Craig R.

I CHARLOTTE,NC 28273 WS 704-527-11 ( 704-527-1133 33(faft x) PMay 1,2008 Mr.Roger C.Edwards NC Division of Water Quality 2090 U.S.Highway 70 Swannanoa,NC 28778 Subject: Section 404 Individual Permit Application Asheville Regional Airport Expansion Fletcher,North Carolina DWQ Project#07-1841 CWS Project No.2007-1899 Mr.Edwards: In your letter dated March 20,2008 you provided the need for the following information in order for the project to be reviewed in the future as a complete package: • This office determined that your submitted Impact Justification was insufficient. In your response, you quoted the application, the suitahility of disposing of fly ash as structural fill was referenced.As disposing of a waste product is not a reason to fill a Waters of the State, the alternatives were reviewed without consideration of these statements. The use of flyash as a fill material has been removed from the alternatives and purpose and need for the development of this project. The following is the revised Alternatives Analysis: Alternative 1 -No Build Alternative y _._..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. 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 would also require land acquisition by the airport. Alternative 3—West Side Development Alternative The West Side Development Alternative will result in impacts to 2,371 linear feet of jurisdictional streams and also does not satisfy project purpose and need since it does not have access to four lane interstate and terminal. The USGS topographic map shows a"blue line" stream in this location. This area doesn't have existing support infrastructure(access,utilities, taxiways,aprons,etc). In order to access the airport terminal from this area,all traffic will need to cross the runway which will cause safety issues and could delay flights. NORTH CAROLINA • SOUTH CAROLINA NEW YORK WWW.CWS-INC.NET May 1, 2008 Mr.Roger Edwards Page 2 of 5 Alternative 4—South Side Development Alternative The South Side Development Alternative will result in impacts to approximately 2,818 linear feet of jurisdictional streams 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 cannot be adjacent to Runway/Taxiway system due to Rental car Facility. The elevation of this piece of land is 30 feet lower than the existing development and it cannot be filled due to the location of the rental car facility. Alternative 5—East Side Development Alternative The East Side Development Alternative will impact jurisdictional streams or wetlands but does not satisfy project purpose and need since it is not adjacent to airstrip and does not have enough land area to provide the necessary program elements. This alternative is located across NC-280 and will have no access to Runway/Taxiway System unless a taxiway bridge is built to span the highway. A bridge of this nature would not be cost effective for this project. In addition,the land area geometry and size is not adequate for the development. 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. 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 100,000- -new square feet of building and approximately 150,000 new square feet of roadway and parking. This alternative will provide access to I-26 via NC-280. This alternative is consistent with FAA approved Master Plan and Land Use Plan Alternative 8—An additional alternative suggested by the NCDWQ was to relocate the stream to the east side of the development. The topography of the site will not allow a proper relocation of the stream due to the drastic elevation change across the site. • Your minimization statement regarding the "minimization of impacts to downstream aquatic resources"does not address the steps taken to minimize impacts on-site. The following information is taken from the Avoidance and Minimization section of the REVISED Individual Permit Application. Impacts were reduced for the Preferred Alternative by reducing the fill slopes from 4:1 to 3:1 on the north end of the development. A retaining wall and wing walls were added to the north outlet of the 60"RCP to further reduce impacts. The use of the rip rap apron was avoided through the use of an internal energy dissipater to the pipe. The energy dissipater will be in accordance with NC Erosion and Sedimentation Control Planning and Design Manual,Section 6.41.1. The system was designed with an O-Ring Gasket RCP pipe to seal out ground water from the pipe. This minimization strategy has reduced stream impacts by 441 linear feet and wetland impacts by 0.158 acre from the original proposed activities. 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. Negative effects to downstream water quality and May 1, 2008 Mr.Roger Edwards Page 3 of 5 important aquatic functions and values will be prevented through appropriate erosion and sediment control methods during construction and the incorporation of permanent storm water management measures designed to remove Total Suspended Solids (TSS) before they reach downstream receiving waters. Alternatives 2, 3, 4, and 5 refer to the project not having direct access to-26. The proposed preferred alternative does not have direct access to 1-26 either. Vehicular traffic will have to enter Airport Road in order to access 1-26. Should additional construction be required to provide such vehicular access to 1-26, it must be reflected in the project plans and any impacts associated with this access are considered collectively with the requested impacts. Additionally, if no new vehicular access to 1-26 is proposed, and the existing Airport Road access is utilized, this argument against Alternatives 2, 3, 4, and 5, can be removed from the alternatives analysis. These alternatives will have access to I-26 via NC-280. There is a potential opportunity to have a direct exit from I-26 in the future to solely serve this airport. A conceptual design for a direct airport entry from Southbound I-26(exit 40)has been included. Alternative 3 indicates that there would be impacts to waters related to this alternative, but no supporting data was submitted(Including, but not limited to, amount of impacts compared to Alternative 7.)Additionally, this is the only alternative which states that direct access to the existing terminal to be necessary for the project. If direct access to the terminal is not integral to Alternative 7, then this argument cannot be used for alternative 3. See the above Revised Alternatives Analysis. If an alternative has potential to impact jurisdictional waters,the impact is estimated using GIS data. -Alternative 4 states that"it does not enough land area adjacent to both airstrip and interstate."As neither your Purpose and Need nor your Avoidance and Minimization dictates how much adjacent land to both the airstrip and interstate is required, this argument is invalid. Aerial Photographs of the Airports property have been included and show graphically where --- each alternative was considered.(Figures 1 and.2,enclosed),_ Alternative 5, with the fly ash disposal and direct access to both the airstrip and interstate arguments removed(access to the airstrip can always be created through a paving expansion of taxiways and service aprons), is an alternative which should be explored. The land area geometry and size is not adequate for the development. The construction of a bridge to span NC-280 is not cost effective for this development. o Alternative 6 re-states the "no negative effect"to downstream water quality,yet on-site observations conducted by the Division and the US Army Corps of Engineers on March 12, 2008 revealed that fly ash and sediment have already been discharged to streams and wetlands on-site. Please see the next bullet point to address the flyash cleanup. A detailed report by Vaughn Engineering has been attached to demonstrate the steps taken to install the Geosynthetic Clay Liner. A report from Silar Services detailing the monitoring well installation and monitoring plan has been included. In your response to the "clean fill"requirement of the State,you have not provided a compelling argument as to why this material must be filled over the stream and wetland.Additionally,you have not provided the requested monitoring plan which would show how the ash placed to the side of the stream and wetland will not violate Water Quality Standards. Lastly,you have not addressed how subsurface water moving below the fill layer would not pick up pollutants and discharge then to downstream systems. May 1, 2008 Mr.Roger Edwards Page 4 of 5 The following is the detail of the measures taken to clean up the flyash that was observed in the stream and wetland. It was requested by Kevin Barnett,with the Division of Water Quality(DWQ),to provide a detailed narrative of the cleanup process that we have completed with respect to the above referenced notice of violation,this report is intended to satisfy his request. Attached,please find our photographs of the impacted area where sediment and erosion control measures were compromised,taken on Wednesday,March 12,2008,during the subsequent site visit.Also attached,please find the pictures of the same impacted area,taken after our cleanup efforts,of Friday,March 15,2008. With the intent to restore the impacted area in question to its original condition,we manually used rakes and shovels to carefully collect only the ash and sediment that had been discharged. All of the excavated soil was manually deposited into 5 gallon pails and returned to the structural fill area currently under construction. Care was taken,to not disturb any other functions or characteristics of the stream and wetlands.. All erosion control measures have been repaired,operational and inspected.Weekly and stormwater reporting are being documented and reported to DWQ as per plan.- You have failed to provide an adequate stormwater management and treatment plan for the existing impervious surfaces. A Stormwater Pollution Prevention Plan (SPPP)template is being developed for the North Carolina Airport Association (NCAA)that will provide guidance on best management practices (BMPs)that should be followed by NCAA-member airports to prevent or reduce stormwater pollution from their industrial activities. As such,Asheville Regional Airport will implement BMPs,including fuel disposal barrels and ramp sweeping activities for the General Aviation ---- Apron Area-to-help treat-stormwater_runoff from.the-existing impervious areas.- ------ ------ - Please do not hesitate to contact me at 704-527-1177 or through email at craig@cws-inc.net should you have any questions or comments regarding these findings.

We will continue to inspect the liner installation accordingly as required.. Soil and Erosion Control: In case of breach,such that visible ash or sediment is leaving the disturbed limits of the site, corrective action shall be taken immediately to terminate further discharge. Additionally,the Division of Water Quality(DWQ)will be notified within 24 hours of discovery and a report the-corrective measures taken-will'ue-submitted to-DWQ-within i-S-days: fit a minimum,the source of the breach will be identified and repaired sufficient to avoid a fiiture release. Following repair, the entire sediment control system will be evaluated to establish if the breach was an anomalous occurrence or if additional measures need to be taken to provide sufficient sediment control and protection of water quality. Additional measures could include; providing additional rows of silt fencing,sediment collection areas,better stabilization of existing controls,and/or more frequent inspections. Records of corrective measures,whether temporary or permanent,taken at the site will be maintained onsite and will be distributed to DWQ. Ground water Monitoring: There have been four monitoring wells installed both up gradient and down gradient. Please see attached groundwater monitoring well location and ground water table data. We believe that the above measures provide suitable protection of the stream and wetlands downstream of the project and comply with requirements of the non-discharge permit. Charah will continue to monitor and report this water table data for five years following ash placement completion. We will work with the Aquifer Protection Section to provide whatever groundwater information as required. CONSERVING OUR NATURAL RESOURCES 1. rTHROUGH THE BENEFICIAL USE OF CCPs 1 Y um.

From: Tim.Silar—Silar Services Incorporated Date:April 15, 2008 Subject: Hydrogeologic Assessment Status Report Charah Inc. (Charah) has requested that Silar Services Incorporated (SSi) conduct a hydrogeologic assessment to addresses requirements related to Permit Number WQ0000020 issued by the North Carolina Department of Environment and Natural Resources (NCDENR), specifically - evaluate seasonal high water table as per section II. Operation and Maintenance Requirements, 9b. To accomplish this objective groundwater monitoring wells will be installed and initial water level data have been collected. These activities are summarized below. Monitoring Well Installation Four monitoring wells were installed in early January 2008 to provide groundwater elevation measuring points and thereby an understanding of groundwater conditions. The monitoring wells will be installed by a Geologic Exploration from Statesville, NC using hollow-stem auger and air rotary techniques and constructed in accordance with Federal and State guidelines. The location of the monitoring wells is illustrated on Figure 1. A summary of the monitoring wells construction is included in Table 1. Monitoring wells were screened across the water table (first water). Water Level Measurements Continuous water level measurements have been collected from monitoring wells MW-1 and MW-2 to gain requisite data to access the seasonal high water elevation. Measure are collected with in well pressure transducer at a frequency of one reading every ten minutes. A summary of water level elevation from MW-1 from January 4 to March 4, 2008 are included in Figure 2. This data indicated that the groundwater water elevation has fluctuated in a narrow range from approximately 2,087.3' to 2,088.7' above mean sea level (MSL). Summary Four monitoring wells were installed to evaluate groundwater elevation in the project area. Water levels collected to data indicates that groundwater elevations fluctuate in a narrow range with a maximum groundwater elevation of less than 2,089' MSL.

Edwards, Jr. Asheville Regional Airport Authority 61 Terminal Drive Suite 1 Fletcher, North Carolina 28732 Subject Property: Asheville Regional Airport Expansion Fletcher, NC RETURNED AS INCOMPLETE Dear Mr. Edwards: 'On October 29, 2007, the Division of Water Quality-(DWQ) received your application submitted in regards to your request to perform filling.activities within 1746 linear feet of streams and 0.209 acres of wetlands. The Division of Water Quality requested additional information in the form of an Additional Information Request mailed January - 23, 2008. A response was received from you on February 22, 2008. The DWQ has determined that your application and additional information are insuffient in order to make an agency determination. Therefore, we are returning your application as incomplete in accordance with 15A NCAC 2H .0506. In order for your project to be reviewed in the future, you must. submit a complete application along with the appropriate processing fee, including, but not limited to: • This office determined that your submitted Impact Justification was insufficient. In your response, you quoted the application, the suitability of disposing of fly ash as structural fill was referenced. As disposing of a waste product is not a reason to fill a Waters of the State, the alternatives were reviewed without consideration of these statements. • Your minimization statement' regarding the "minimization of impacts to downstream aquatic resources" does not address the steps taken to minimize impacts on-site. North Carolina Natill'ally North Carolina Division of Water Quality 2090 U.S.Highway 70 Swannanoa,N.C.28778 Phone(828)296-4500 Internet: www.ncwaterguality.org Customer Service 1-877-623-6748 FAX (828)299-7043 An Equal OpportunilylAffirmative Action Employer—50%Recycled110%Post Consumer Paper Asheville Regional Airport Expansion Page 3 of 3 , March,20,2008 • Alternatives 2, 3, 4, and 5 refer to the project not having direct access to 1-26.. The proposed preferred alternative does not have direct access to 1-26 either. Vehicular traffic will have to enter Airport Road in order to access 1-26. Should additional construction be required to provide such vehicular access to 1-26, it must be reflected in the project plans and any impacts associated with this access be considered collectively with the requested impacts. Additionally, if no new vehicular access to 1-26 be proposed, and the existing Airport Road access be utilized, this argument against Alternatives 2, 3, 4, and 5, can be removed from the alternatives analysis. • Alternative 3• indicates that there would be impacts to waters related to this alternative,. but no supporting data was submitted (Including, but not limited to, amount of impacts compared to Alternative 7.) Additionally, this is the only alternative which states that direct access to the existing terminal to be necessary for the project. If direct access to the terminal is not integral to Alternative 7, then this argument cannot be used for alternative 3. • Alternative 4 states that "it does not enough land area adjacent to both airstrip and interstate." As neither your Purpose and Need nor your Avoidance and Minimization dictate how much adjacent land to both the airstrip and interstate is required, this argument is invalid. • Alternative 5, with the fly ash disposal and direct access to both the airstrip and interstate arguments removed (access to the airstrip can always be created through a paving expansion of taxiways and service aprons), is an alternative which should be explored. • Alternative 6 re-states the "no negative effect" to downstream water quality, yet on-site observations conducted by the Division -and the US Army Corps of Engineers on March 12, 2008 revealed that fly ash and sediment have already been discharged to streams and wetlands on-site. • In your response to the "clean fill" requirement of the State, you have not provided a.compelling argument as to why this material must be filled over the stream and wetland. Additionally, you have not provided the requested monitoring plan which would show how the ash placed to the side of the stream and wetland will not violate Water Quality Standards. Lastly, you have not addressed how subsurface water moving below the fill layer would not pick up pollutants and discharge then to downstream systems. • You have failed to provide an adequate stormwater management and treatment plan for the existing impervious surfaces. Asheville Regional Airport Expansion Page 3 of 3 t __ March,20,2008 As you have no authorization under Section 401 of the Clean Water Act for this activity, any work within waters of the state would be a violation of North Carolina General Statutes and Administrative Code. Please call Mr. Kevin Barnett at 828-296-4657 if you have any questions this matter. Sincerely, Roger C.

Edwards, please see the following responses: DWQ Request: 1. Impact Justification (Avoidance and Minimization) Under Section Vll of your application you have not provided a 'justification"for the impacts as requested within this section. Additionally, there are no "alternatives" presented for this fill activity. At a minimum,you must explore all other available properties for possible utilization for this proposed expansion. Response: The following is an excerpt from the USACE IP-404 Permit Application: Alternatives I. Avoidance 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 61 Terminal Dr.,Suite 1,Fletcher,NC 28732 • Phone 828-684-2226 • Fax 828-684-3404 www.flyavi.com FAA restrictions on open water and forested buffers adjacent to runways due to safety issues. II. . Minimization Minimization of impacts to downstream aquatic resources will be accomplished by filling the area so that grade directs storm water flows away from surface waters and into off- line storm water BMP treatment measures. The Asheville Regional Airport Authority and its agents have 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 impacts to jurisdictional streams and also does not satisfy project purpose and need since it does not have direct access to four lane interstate and terminal. The USGS topographic map shows a "blue line" stream in this location. 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 have 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 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 storm water management measures designed to remove Total Suspended Solids JSS) before they reach downstream receiving waters. Alternative 8—An additional alternative suggested by the NCDWQ was to relocate the stream to the east side of the development. The topography of the site will not allow a proper relocation of the stream due to the drastic elevation change across the site. DWQ Request: 2. As the Division of Water Quality utilizes it's General Certification as Guidance for Individual Impacts requests, and the General Certifications specify clean fill,your proposed use of fly ash is not suitable for use in filling streams and wetlands. You must re-submit your request showing the Non-Discharge Permit setbacks, with appropriate liners and monitoring to ensure that water quality standards are not contravened. Response: As shown in the enclosed drawings, the creek and wetlands will be filled with clean fill material from nearby borrow areas or quarries (porous material discussed below). This fill will be of sufficient depth to cover by at least two feet the top of the pipe that will convey the relocated stream. As required in Condition II. 9. of the non-discharge permit, approval will be obtained from the Aquifer Protection Section of the Asheville regional office for this design that protects the stream and groundwater with clean fill and a geosynthetic clay liner with a maximum hydraulic conductivity of 10"6 cm/sec. These measures, along with the containment of the stream within the pipe,justify waiver of the prohibition of ash placement within 50 feet of surface water, as allowed by the permit. There are no water supply wells or springs within 100 feet of the fill. The ash non-discharge permit requires the bottom of the ash fill to be a minimum of one foot above the seasonal high groundwater level. With regard to potential contact with groundwater, the project will have porous material in the former steam bed and under the reinforced concrete pipe to allow for drainage of groundwater from underneath the fill and therefore impede the groundwater table from reaching the bottom of the ash fill. As stated above, both the former stream bed and the reinforced concrete pipe will have a minimum of two feet of clean fill over them, and for an extra measure of protection, a geosynthetic clay liner over the clean fill and under any ash fill. When completed, the project will have a six feet thick compacted clean fill "cap" over it and it will then be mostly paved with an engineered drainage system to divert stormwater around the fill, so infiltration of water into the fill is expected to be minimal. The side slopes will have at least two feet of clean fill over the ash fill. We believe that the above measures provide suitable protection of the stream and wetlands downstream of the project and comply with requirements of the non-discharge permit. If the Division deems monitoring is necessary, there is an existing monitoring well both up gradient and down gradient. We will work with the Aquifer Protection Section to provide whatever groundwater monitoring is required. If necessary, samples may also be taken from the stream at appropriate locations both upstream and downstream of the activity after the project is completed. DWQ Request. 3. As it was observed that nutrients and petroleum products were making their way into the stream system,your submitted stormwater collection and treatment system must also capture an treat all impervious areas adjacent, or connected to, this fill activity to adequately treat said runoff prior to discharge. Response: The submitted stormwater collections system was intended to separate all new impervious and pervious development stormwater runoff from the existing airport stormwater system.This was to be accomplished through the extension of the existing 60" RCP storm drain outlet, allowing no addition flow. The airport will work with their engineer to propose a practicable stormwater collection and treatment system solution. We thank you for your time in this matter. If you have any questions or require additional information, please do not hesitate to contact me. Sincerely, Asheville Regional Airport Authority David N.
