(agent) has prepared the attached revisions to the Individual Permit (IP) Application submitted on August 20, 2009 requesting a Section 401 Water Quality Certification for unavoidable impacts to jurisdictional waters and wetlands resulting from the proposed runway extension project and past impacts at the Macon County Airport. The revised cumulative impacts associated with these projects now include 7.01 acres of freshwater wetlands and 809 linear feet of stream. Compensatory mitigation is currently still available through payment to the NCEEP In-Lieu of Fee program. The original (August 2009) Individual Permit application described cumulative impacts as 1,011.36 linear feet of stream and 6.42 acres of wetlands. The attached revisions have been made based on comments and recommendations from the United States Army Corps of Engineers (USACE) Asheville Regulatory Office following their initial review. These revisions include the following: Stream impacts reduced from 1,011.36 linear feet to 809 linear feet: The USACE has recommended removing stream channel impacts resulting from the 2006 perimeter fencing project from the cumulative impact total. Since the Airport Authority proposes to remove the un-permitted culverts and restore stream channels in-kind to their pre-construction conditions, the USACE considers these impacts temporary. Also, the total length of stream to be restored was listed as 202.5 linear feet in the original application. This total has now changed due discrepancies listed in the pipe lengths. Pipe #4 was described as a 21 inch CPP extending 30 feet. The correct description is a 30 inch CPP extending 21 feet. Pipe # 8 was described as a 34 inch CMP extending 20 feet. The correct description is 24 inch CMP extending 10 feet. The 11 ;tit Oriw correct total of linear feet that will be restored is 183.5 linear feet and is described in Section 2.6.5 of the attached revised permit narrative (October 2009). Supplemental soils investigation in area of Wetland G: The USACE requested that Wetland G be re-delineated in order to identify a finer hydric soils boundary since only one hydric soils profile was identified during the April 2009 Licensed Soil Scientist (LSS) investigation. Wetland G is considered "atypical" since all three wetland parameters cannot positively be identified due to past land disturbances. A new boundary was delineated during September 2009. This boundary reduced the acreage of Wetland G from 1.56 acres to 0.83 acre (Figure 8). Because of the atypical characteristics of Wetland G and the un-permitted ditch maintenance observed by regulatory personal during May of 2007, the USACE is requiring that the Airport Authority mitigate for previous impacts to Wetland G. In order to determine impacts, the USACE is using the 1991 jurisdictional determination (J.D.) boundary to decide the size of the impact (Figures 3 and 8). As a result, a total of 0.43 acre has been included in the cumulative impacts for un-permitted ditching within Wetland G. Proposed filling and grading of wetlands in Eastern Floodplain: Through many discussions with both the DWQ and the USACE, it has been noted that wetlands located in the eastern floodplain (Wetlands F/G, G, GA, and GB) are within an area that must be maintained free of wildlife attractants. FAA regulations require that areas surrounding the immediate 500 feet of the runway surface or the Object Free Zone be free of objects non-essential for air navigation or aircraft ground maneuvering purposes. This includes standing water to eliminate potential attractants and reduce collisions with wildlife. In the original application, the Airport Authority proposed continual maintenance of these areas through ditching, which has not been entirely effective since wetlands still exist within these areas. Instead, the Airport Authority is now proposing the filling and grading of 4.17 acres of wetlands (Wetlands F/G, G, GA, and GB) located within 500 feet of the Object-Free Zone in order to comply with FAA safety standards. Additionally, the USACE determined that Ditch 1 located within the boundaries of Wetland F/G is not jurisdictional, which reduced the wetland acreage of F/G from 2.88 acres to 2.72 acres. Compensation for previous unsuccessful mitigation locations: In 1993 the Macon County Airport was issued Section 404 and Section 401 permits for the construction of the parallel taxiway. The permit requirements included the creation of several onsite mitigation locations for compensation of unavoidable impacts. Currently, only one onsite mitigation location is functioning. As a result, the USACE is requiring compensation for the remaining 1.29 acres of non-functioning mitigation areas. The original application only accounted for 0.43 acre of the 1993 mitigation locations. The following tables have been taken from the original submission (August 2009) and the revised October 2009 documents in order to compare changes in stream and wetland impacts. c/fe/97084/5-7asbi I. doc Ori ginal Cumulative Impact Table (Submitted in August 20 Im acts Jurisdictional Waters & Wetlands Stream (Linear Feet) Wetland (Acres) lotla Branch 748.86 Wetland 1 0.06 Wetland 2 0.05 Wetland 3 0.06 Alder Bog 1.38 Fence impacts (Temporary) 202.5 Equipment Access Culverts 60 Wetland G 1.56 Wetland F/G 2.88 1993 Wetland Mitigation Site 0.43 Total 1,011.36 6.42 Revised Cumulative Impact Table (October 2009) 09) Im acts Jurisdictional Waters & Wetlands Stream (Linear Feet) Wetland (Acres) lotla Branch 749 Wetland 1 0.06 Wetland 2 0.05 Wetland 3 0.06 Alder Bog 1.38 Equipment Access Culverts 60 Wetland F/G 2.72 Wetland G 2009 Delineation 0.83 Wetland G 1991 delineation 0.43 Wetland GA 0.11 Wetland GB 0.08 1993 Wetland Mitigation Site 1.29 Total 809 7.01 c/fe/97084/5-7asbi I.doc Additional revisions have also been made to the Stormwater Management Plan described in Section 5.3 of the permit narrative. These revisions result from recent survey data taken on newly installed NCDOT culverts located under S.R. 1434. The NCDOT replaced the eroded double 60" culverts under S.R. 1434 to prevent a possible failure of the culverts and roadway. Since the proposed project will tie into the newly installed culverts, the updated survey data has been incorporated into the design which has resulted in changes to pre-construction and post-construction stormwater conditions. The following is a list of the attached revised documents that need to be incorporated into the original permit binders: • Macon County Permit Application and Narrative October 2009: Replace the August 2009 version with the Revised October 2009 version.

U February 2009 (Revised October 2009) C? 1.0 Introduction Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application On behalf of the Macon County Airport Authority (Owner), WK Dickson & Co., Inc. (Agent) is requesting a US Army Corps of Engineers (USACE) 404 Permit, a NC Division of Water Quality (DWQ) 401 Water Quality Certification, and a Tennessee Valley Authority (TVA) Section 26a Shoreline Construction Permit for: the proposed extension of Runway 7, associated taxiway and Runway Safety Area (RSA), and for impacts associated with past runway maintenance projects. In total, the cumulative impacts result in permanent losses to 7.01 acres of freshwater wetlands and 809 linear feet of stream. Additionally, the Airport Authority is proposing to restore 183.5 linear feet of stream previously impacted by the placement of un-permitted culvert pipes. The airport facility is a general aviation airport utilized by business and recreational aircraft and is located within the lotla Valley on Airport Road (SR 1434) approximately 3 miles north of the town of Franklin, Macon County, North Carolina (Figure 1). The project area is located at approximately 35.2225952 N and -83.4190441 W within the Little Tennessee River Watershed (HUC 06010202). The nearest surfaces waters are lotla Branch and lotla Creek (Refer to USGS Map, Figure 2). DWQ has classified both lotla Branch and lotla Creek as Class C waters. As defined by the DWQ, Class C waters are protected for uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including propagation, survival and maintenance of biological integrity, and agriculture. is Seven structures currently exist within the airport property (the main terminal, an office, a maintenance hangar, and 4 T-hangar buildings). 2.0 Application for Department of the Army Individual Permit 2.1 Nature of Activity (Block 18) The overall nature of activity includes extending Runway 7, associated taxiway, and RSA 600 feet to the west. This permit application also includes impacts from previous work resulting from ongoing runway maintenance projects that have occurred primarily within the last 18 years. The extension of Runway 7 includes the filling and grading of 749 linear feet of lotla Branch (tributary of lotla Creek) and 0.17 acre of abutting and adjacent wetlands including Wetlands 1, 2, and 3. Of the 749 linear feet, 139 linear feet will be relocated to an open rock-lined channel in order to divert hydrology into 575 feet of 72 inch reinforced concrete pipes (RCP) and 130 feet of double 60 inch RCP. The newly installed pipes will tie into the existing double 60 inch RCP culvert located under Airport Road and outlet into lotla Creek south of the runway (Figure 4). This permit application also includes impacts from various un-permitted activities performed within the last eighteen years in waters and wetlands of the U.S near the • runway. First, fill material was placed in 1.38 acres of freshwater wetlands previously identified as an alder bog (Wetland AB) north of the runway (Figures 3 & -1- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application 7). It has been determined that this occurred during the construction of the 1991 runway extension. Secondly, 60 linear feet of stream throughout the property contains un-permitted culvert crossings (Pipes #11, #12, and #13) for accessibility of mowing equipment (Figures 7 & 8). Thirdly, in order to address an ongoing runway safety issue specifically to avoid bird air strike hazards and to comply with FAA runway safety regulations (FAA Advisory Circular 150/5200-33B, 8-28-2007 and FAA Advisory Circular 150/5300-13, 9-29-2006, Appendix Q), the Airport Authority is currently proposing to fill wetlands located within the eastern floodplain including Wetland F/G, Wetland G, Wetland GA and Wetland GB (Figure 8). In the past the airport has attempted to maintain these areas through ditching which proved to be ineffective. Finally, several wetland mitigation sites constructed in 1994 have also been identified throughout the eastern floodplain. The development of the onsite wetland mitigation areas was required as compensatory mitigation under authorization of the Section 404 (Nationwide 26) and Section 401 permits issued in 1993 for impacts resulting from the construction of a parallel taxiway. Currently, the majority of these mitigation areas are non-functioning. As a result, the USACE is requiring additional compensation for the unsuccessful mitigation areas created during the 1994 taxiway construction project. The non-functioning wetland mitigation sites include 1.29 acres and have been included in the cumulative i m pacts. • Additionally, in 2006 culverts were installed throughout the perimeter of the airport property during the upgrade of the security fence without proper authorization. This resulted in un-permitted impacts to 183.5 linear feet of stream (Figures 7 & 8). The airport is currently proposing to remove all culverts associated with the fencing project and restore the impacted stream channels to their pre-construction conditions. 2.2 Project Purpose (Block 19) The purpose of this project is to bring the Macon County Airport in compliance with the North Carolina Division of Aviation and FAA safety standards. Such standards require having at least 5,000 feet of available runway and appropriate runway safety area to improve the overall safety of the airport. Currently, the existing 4,400 foot long runway and extended runway safety area at Macon County Airport does not meet this requirement for the aircraft operating on the runway. Because of this, the Macon County Airport does not provide an enhanced facility for distressed aircrafts in emergency situations. Having such a facility at the Macon County Airport is vital to the major surrounding national and regional airports located in Asheville, Charlotte, Knoxville, Greenville, and Atlanta. Construction of the runway extension is anticipated to begin once all required permit approvals have been obtained. This project will be funded through grants already issued from the FAA and NCDOT Division of Aviation. • Additionally, the airport must also maintain the runway in compliance with FAA safety standards as well as the Clean Water Act (CWA) Sections 404, 401 and the Tennessee Valley Authority Act Section 26a. FAA regulations require that the -2- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • runway safety areas remain clear of all objects not fixed by function (i.e. runway lights, NAVAIDS). Additionally objects that are wildlife attractants should be removed from the nearest air operations area that extends to 5,000 feet for piston- powered and 10,000 feet for turbine-powered aircraft in order to avoid potential aircraft collisions with wildlife (Appendix Q). In order to bring the Macon County Airport into regulatory compliance, previously un-permitted wetland impacts as well as unsuccessful compensatory mitigation locations from the 1993 404/401 permit application for the taxiway construction have been included in this permit application. Compensatory mitigation is proposed for all of the project's anticipated impacts, previously un-permitted impacts, and past unsuccessful mitigation. • -3- V O 0 a O Z rz Q _ W Q t = Q� Qcc w t V O j �0 Q O O U� aaJ� { 9 la _ - 0 o o a a i Y /a� L= 0, s9 NG�tyoil P P O Ferguson .gy r, s N o w C uollea paj=jl a 8 sjapuneg co w Gr°�ja A Hoa l� i s64lu e '•�� aii� a a Gr japuo ooh i\el � m G°s JAZ C _ illvie Iarks C N ° yl e � a Cra Lu tiJae wig G x a ° Pann e e Bro Fav- a I.ak gtlo ;oda0�LL uo °lej . \\ u w off � •�: � 4P ) V 0 oy iseuel a ec _ N = 0 ~ \\G A Ja��S ell A o w \\m �(J\\'a l l o Parsons o e ` m`> Q '.0 u tie S c\ 00 a o od o `—° rN `� a m Nell m `O�j ° 00 p °' m `p% an cj CD ueo S c -00 uaneypoo e`� b Q y Idro ? a�oOSI aero g°j o �� A4,Ci cry mac pooM� Pine r Gb t O ArborMay s o o yuGi Ge S i kp c m m ti�C s 9°`)gyp 40 iU° N �sv� �\n p� 6' Q`Qe �,`JB � GcG to o a 0 \c i Five ' a y1l 2 ° � ve o O P m O uts Y Gr° M r Fore t 0 p p m o (� O LMis PIO o J i ;nu;say U Q Grannys 10o a Jas n p /q / �e o Country Club M� V O 0 a O Z rz Q _ W Q t = Q� Qcc w t V O j �0 Q O O U� `1 4 r 1 �,'+,fir, � -�// J `. � � ` - , rrr • I ;''L f ' �,t ' �Avoo w -J a, �.' � u r, s._� - � •'C. � p rig / . h. - � � !!� 1 ' r `', , � ,.

Current FAA and state regulations require a minimum of 5,000 feet of available runway and appropriate runway safety area to be in compliance with current safety standards. Additionally, wetlands have been drained and filled in the past as a result of maintaining the Object Free Zone a 500 foot area surrounding the runway as noted in FAA Advisory Circular 150/5300-13 and to reduce the chance of wildlife collisions by removing wildlife attractants within the airport property per FAA Advisory Circular 150/5200-33B (Appendix Q. 2.4 Type & Amount of Material Being Discharged in Cubic Yards (Block 21) It is proposed that approximately 115,000 cubic yards of clean material will be utilized to construct the runway, runway safety area and parallel taxiway resulting in the filling of Wetlands 1, 2, and 3 and a portion of lotla Branch for the runway extension. Approximately 30,000 cubic yards of clean material will be utilized to fill wetlands located in the eastern flood plain (Wetland F/G, Wetland G, Wetland GA and Wetland GB). It is estimated that approximately 2,350 cubic yards of local upland soil was utilized to fill the alder bog wetland (Wetland AB) during 1991. 2.5 Surface Areas of Wetlands or Other Waters Filled (Block 22) Table 1. Proposed Impacts from Runway Extension Project Aquatic Resource Proposed impact lotla Branch 749 linear ft. Wetland 1 0.06 acre Wetland 2 0.05 acre Wetland 3 0.06 acre Total Impact 749 ft. & 0.17 acres 2.5.1 lotla Branch Approximately 749 linear feet of stream channel identified as lotla Branch is located within the proposed runway and taxiway extension area. During onsite investigations, the surrounding landscape of lotla Branch included rolling terrain of grass - covered fields. lotla Branch was identified as a relatively permanent waterway (RPW) and second order stream. Its headwaters are northwest of the airport property. lotla Branch flows south into lotla Creek (south of the project area), and eventually into Little Tennessee River. At the time of the investigation riparian vegetation along lotla View of lotla Branch taken on 4-16-07. -7- 0 • February 2009 (Revised October 2009) Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application Branch had been cut down and is continually mowed for runway safety and obstruction purposes. It is dominated by tag alder (Alnus serrulata, FACW+). Additional species observed within the riparian corridor include swamp dogwood (Cornus stricta, FACW-), black willow (Salix nigra, OBL), soft rush Uuncus effusus FACW+), and bearded sedge (Carex comosa, OBL). lotla Branch was identified and delineated during the initial wetland investigation performed on April 16, 2007. The USACE field verified this stream as jurisdictional on May 30, 2007. The proposed design includes relocating a portion of lotla Branch (139 linear feet of the total 749 linear feet) into an open rock lined channel (Figure 4) parallel to the runway. Mitigation for relocating this portion of the stream channel is proposed at a ratio of 1:1 per recommendation of the USACE. Mitigation for the remainder of lotla Branch (610 linear feet) is proposed at a 2:1 ratio due to the quality of the stream and recommendation of the USACE (Table 6: Proposed Mitigation). 2.5.2 Wetland 1 Wetland 1 is a linear palustrine emergent wetland that abuts lotla Branch to the northeast (Figure 3). Due to the shape, it is likely that Wetland 1 was formerly a man-made agricultural ditch that eventually reverted into a wetland community. At the time of the investigation, vegetation along the wetland boundaries had been mowed. The airport continually maintains this area for runway safety. During the onsite investigation, it appeared that black willow and swamp rose (Rosa palustris, OBL) once dominated. Additional vegetation observed included soft rush, spikerush (Eleocharis obtusa, OBL) and sedges, (Carex, spp. FACW). Soils from 0 to 12 inches were loam with a dark grayish brown (10 YR 4/2) matrix and many common yellowish red (5YR 5/8) mottles. Wetland 1 was delineated during the initial wetland investigation performed on April 16, 2007. The USACE field verified this wetland as jurisdictional on May 30, 2007. The proposed design includes the filling and grading of Wetland 1. Since Wetland 1 abuts lotla Branch, mitigation is proposed at a 2:1 ratio (Table 6: Proposed Mitigation). 2.5.3 Wetland 2 View of Wetland 2 taken on 4-15-09. 6/8) mottles from 0 to 10 inches Wetland 2 was delineated during April 2009 and is located east of Wetland 1. Wetland 2 is adjacent to lotla Branch. This area was not delineated in any of the previous delineations (1991 and 2007). Wetland 2 is in a topographic depression of a mowed area just north of where runway 7 ends (Figure 3). Soils were silt loam with a very dark grayish brown (10 YR 3/2) matrix and 1 percent of coarse brownish yellow (10YR Soils from 10 to 12 inches were dark olive • • February 2009 (Revised October 2009) Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application brown (2.5Y 3/3) clay loam with 3 percent of coarse light olive brown (2.5 Y 5/6) mottles. Water observed within the boring hole was at 11 inches below the surface. Vegetation observed included fescue (Festuca arundinacea, FAG), mustard (Brassica spp., NI), and soft rush. It is likely that Wetland 2 was created through continual soil compaction from use of mechanized maintenance equipment. As a result, surface infiltration has been reduced within the shallow depression and ponding has been enhanced. The proposed design includes the filling and grading of Wetland 2. Since Wetland 2 is adjacent to lotla Branch, mitigation is proposed at a 2:1 ratio (Table 6: Proposed Mitigation). 2.5.4 Wetland 3 Wetland 3 is located within a topographic depression and is adjacent to lotla Branch (Figure 3). Soils from 0 to 9 inches were a dark brown (10 YR 3/3) loam. Soils from 9 to 10 inches were dark brown (10 YR 3/3) silt loam with 5 percent of coarse brownish yellow (10 YR 6/8) mottles. Soils from 10 to 13 inches were dark reddish brown (5 YR 2.5 /2) clay loam with 5 percent of coarse yellowish red (5 YR 4/6) mottles. Water was View of wetland 3 taken on 4-15-09. observed at the surface. Existing vegetation was a monoculture of soft rush. It is likely that Wetland 3 was also created as a result of continual compaction of soils through mechanized maintenance of the airport property which has reduced surface infiltration and enhanced ponding within shallow depressions. The proposed design includes the filling and grading of Wetland 3. Since Wetland 3 is adjacent to lotla Branch, mitigation is proposed at a 2:1 ratio (Table 6: Proposed Mitigation). rA C� LLI V) ry (.D UJ U) LLJ < 0 (n LLJ /0-U) . - I I o GL 0 Cf) C, 3.1 LLJ C� LLI V) ry (.D M-4 0 0 �-- < . - I I , C, 3.1 LLJ V) 0!.' 0 u 1: LJ C) t LLI LLI V) 1-- u LJ V) 0 X W W< D x 0 0 0 cn (D 0 C) I Z -.g a- 07 0 x < Li 0 W 0 Z U < < to 0- w0 z X Z w> D M-4 0 0 �-- . - I I , 3.1 LLJ V) 0 u 1: LJ LLI LLI V) 1-- 0 >LLI 0 X W W< D x 0— 0 0 0 C) I Z -.g a- 07 0 x < z "Of 0 Z U < < to 0- w0 z X Z w> D < Z 0 < < of z cl� z E z a - < z U LL - 0 C) < < < ci Z wZ WW0 2O2 W U� C) cn 0 — I-- z _j LLJCo o 0 < LLJ < < of LLJ LLJ In 0 LLJ < 0 LLJ < LLJ Cf) Ln < LLJ > cn Of < Of LLJ < 0 U a- - Of LL- o L L -Li —i _j 0, w < 0 ol -Li D 0!� < 3: < z < z Z 0 CI- 0 w cn0 0 m < Qom a- 0 LLI Q F-- (-) 0 0 C7 0 Z F- V) 0 LLI cn Q C) (J) Z F- X 0 a< - 0 c/,) < V) V) cn a- x D D Ld Q- CD --D --D —j LLJ < 'y T 1 1-1 z C) C) z Lij Lli 0 V, F -- ZI LLI L -J U) < Lj L- at opo Lj 0 o F- x 0 0 < z --j GC CCW LLI 0- 0 LLJ Z (T) 0 cj:� < 0 :;7fi a- o fa -1 cl� LLJ = rl-) o < a- cl� U-) u c—n Z x X Li WI 0 >- 0 + < cn ;0 10 m LLJ LLJ U� Lj 0 0 0 00 U < < (n L'i IL (n -i 0 < < z L'i < cn 0 0 fy p a- �t < J n _j O�� _j a_ 0 1-7 0 E-- 'oo M-4 0 0 U) LLJ LLJ Y) L -Li I U' m U) LLJ LLJ LLJ z :�E C/') Z LLJ U� > < NO 0 0 0 0 3.1 LLJ V) 0 u 1: LJ LLI LLI V) 1-- 0 >LLI 0 X W W< D x 0— 0 0 0 C) 00= Z -.g a- 07 0 x < z "Of 0 Z U < < Lli 0- w0 z X Z w> D < Z 0 < < of z Z O z E z D < cQc C) < ci Z wZ WW0 2O2 W < F-- cn cn 0 — I-- z _j LLJCo o 0 < < Ld of LLJ LLJ < 0 < cn Of < Of LLJ < 0 0 U) LLJ LLJ Y) L -Li I U' m U) LLJ LLJ LLJ z :�E C/') Z LLJ U� > < NO 0 0 0 0 LLJ >LLI C) LLJ > < C) < Z U < < < 0- LLJ < C) < 0 Z wZ WW0 LLJ < U� < F-- cn cn 0 — I-- z _j LLJCo o 0 < < Ld of LLJ LLJ < 0 < cn Of < Of LLJ < Of LL- o <w—i 3: —i _j 0, w LLJ LL - z D D 0!� < 3: < z < z Z 0 CI- 0 w cn0 0 m < LLI Q F-- (-) F--LL- U LLJ 0 C7 Z F- V) 0 LLI cn Q C) (J) Z F- X 0 a< - 0 c/,) < V) V) cn a- x D D Ld Q- CD --D --D —j LLJ < 0 0 U) LLJ LLJ Y) L -Li I U' m U) LLJ LLJ LLJ z :�E C/') Z LLJ U� > < NO 0 0 0 0 • 2030.0 2020.0 2010.0 2000.0 48+00 47+00 50 0 50 100 HORIZONTAL SCALE: 1" = 50' 5 0 5 10 VERTICAL SCALE: 1 5' 46+00 2030.0 2020.0 2010.0 2000.0 45+00 RUNWAY 7 PROFILE MACON COUNTY AIRPORT AUTHORITY RUNWAY EXTENSION PROJECT FRANKLIN, NORTH CAROUNA .,. caa.woE ..,E ? ?D CKSON FIGURE F ,mmaw K ?. wEq. w.we.E. ea.,t.a oud ? 5 = E, ? ¦c umeE ¦n r-nna s. February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • 2.6 Previous Impacts (Block 23) Previous impacts were discussed during the May 2007 regulatory agency site visit at the airport property. As a result, the USACE and the DWQ requested that all impacts (past and proposed) be included in the forthcoming permit application. Additionally, in March of 2009 DWQ requested that the alder bog wetland located north of the runway be included as an impact in the permit application. DWQ also indicated that the Airport Authority's 1993 Nationwide 26 Permit and associated 401 Water Quality Certification drawings (Appendix D) depict large areas of wetlands that were not identified in 2007. To address this inconsistency they requested that the floodplain south of the runway be reviewed for potential fill material. 2.6.1 Background Information Additional desktop and field evaluations were performed during March and April of 2009. Desktop evaluations included a review of 1953 and 1980 NRCS aerial photographs; Google Earth aerial photos from 1994 to 2005; State Climate Office of North Carolina CRONOS precipitation data dating back to 2004 (www.nc- climate.ncsu.edu/cronos); Natural Resource Conservation Service (NRCS) Water and Climate Center (WETS) Table Data; and archived data from North Carolina Drought Management Advisory Council (NCDMAC). Various individuals were also contacted regarding past projects on the property. In • March of 2009, all culverts installed during the 2006 fencing project were identified and mapped. Additional wetlands were also delineated in March and in April of 2009. Finally, in April of 2009, soils throughout the property were evaluated by a North Carolina Licensed Soils Scientist (LSS) in order to determine if any wetlands areas identified in 1993 had been filled. It was later determined by the USACE at the May 6, 2009 interagency meeting that the 1993 Jurisdictional Determination was not signed and therefore the 1991 Jurisdictional Determination was the most recent authorization for the property (Appendix H). 2.6.1.1 Changes in Hydrology During the 2009 wetland investigation, it was noted that hydrologic conditions had changed at the Macon County Airport since the 2007 investigation. In fact, hydrologic conditions have continued to change since the mid 1990's. Currently, wetland hydrology within the airport property is primarily supported by a typically high water table within areas of the floodplain south of the runway. However, following the completion of the taxiway construction in 1994, wetland hydrology within the floodplain has decreased due to the relocation of a stream channel. These activities were permitted through the Nationwide 26 and 401 General Water Quality Certification issued in 1993. In addition, increased drought conditions experienced throughout the region have also lowered the water table at the Macon County Airport during the past nine (9) years. • -13- February 2009 (Revised October 2009) 0 2.6.1.2. WETS Table Data • Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application WETS Table data was reviewed from the Franklin NC3228 WETS Station. Data from this station has been collected from 1971 to 2000. The WETS Table indicates that total average rainfall for Franklin, North Carolina is typically 54.51 inches. According to NC CRONOS Database retrieved from the State Climate Office of North Carolina, the Macon County Airport station (K1 A5) recorded 17.56 inches of annual precipitation in 2007 and 18.95 inches in 2008. The WETS Table also indicates that the growing season is 185 days at a threshold of 28* F or higher and typically begins April 17th and continues through October 19th. 2.6.1.3 Drought Data Archived records from the North Carolina Drought Management Advisory Council (NCDMAC) documented from January 2000 to April of 2009 were reviewed in order to determine if a change in climatic conditions affected hydrology on the property. NCDMAC classifies drought levels from: • D4- Exceptional Drought • D3- Extreme Drought; • D2- Serve Drought; • D1- Moderate Drought; and • DO -Abnormally Dry. Graph 1 represents the changes in Macon County drought levels from 0 (abnormally dry) to 4 (exceptional drought) during the past 9 years. These records were obtained from www.ncdrought.org/archive. Graph 1. Drought Levels from 2000- 2009 Macon County Drought Levels 2000-2009 )-03 1,:n -Ori Jan 09 Drought conditions did not occur between January 2003 and March 2006 and therefore did not receive a drought classification. Macon County -14- • February 2009 (Revised October 2009) Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application experienced the highest levels of drought between April of 2007 and December of 2008 with extreme drought (level 3) and exceptional drought (level 4) classifications. Specifically, Macon County was given a level 4 classification from August of 2007 to December of 2008. As shown in Graph 1, Macon County was downgraded several times to a level 3 within this timeframe, but the majority of months remained at a level 4 classification. At the time of the April 2009 onsite investigations, drought classifications had been downgraded to Moderate Drought (level 1). Changes in climatic conditions likely caused drawdown of groundwater levels below typical conditions. Wetlands delineated during 2009 likely reflect the improved drought classifications relative to 2007. 2.6.1.4 North Carolina Licensed Soil Scientist Investigation To address DWQ concerns regarding the floodplain, a North Carolina Licensed Soil Scientist performed an onsite investigation on April 16, 2009 to identify potential fill material within the floodplain. The results of the LSS investigation found no evidence of fill within the floodplain. Instead, soils were found to be typical of an alluvial floodplain system and the surface horizon contained natural alluvial deposition. Positive evidence of fill material was confirmed within the alder bog wetland (Wetland AB) located on the north side of the runway during the investigation (Appendix Q. 2.6.2 Alder Bog (Wetland AB) The "alder bog" wetland, currently identified as Wetland AB, was initially delineated during the 1991 wetland delineation. The 1991 Wetland Delineation states that the alder bog was once dominated by alders, red maple, buttonbush, swamp rose, sedges and soft rush. The 1991 report also states that this community was probably created when a small tributary of lotla Creek was partially impounded during the construction of the airport (Appendix H). During the April 2009 wetland investigation, Wetland AB was delineated surrounding an unnamed tributary of lotla Creek. Soils from 0 to 3 inches were yellowish red (5YR 4/6) silty loam with large pieces of gravel. Soils from 3 to 8 inches were very dark grayish brown (2.5 Y 3/2) silty loam with 3 percent of coarse light red (2.5 YR 6/8) mottles. Water was observed at 3 inches below the surface. Soft rush was the dominant species. FIX View of Wetland AB taken on 4-15-09. -15- As noted in the LSS report (Appendix C), approximately 6 to 16 inches of fill was identified across most of the former bog. The LSS report also indicates that the fill material appears to be local upland soil, most likely from the adjacent hill slope during the most recent runway extension construction which occurred in 1991. Google Earth aerial photos from 1994 show February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application what appears to be a haul road through the center of this wetland (www.earth. googIe.c:om). Approximately 1.38 acres has been identified as fill and 0.16 has been identified as non-fill during the wetland investigation. The LSS report also states that one soil profile typical of this site is recorded showing 13 inches of fill with the surface containing a dark yellowish brown clay loam. The report adds that redoxomorphic features of brown mottles have begun to form in the fill material from saturation, indicating the fill has been in place for an extended period. It is underlain by black silty clay loam with red and dark gray mottles with a water table observed at 24 inches. Based on the information collected on the alder bog wetland, it is concluded that during the time of the 1991 runway extension, the airport created a haul road through this wetland to construct the extension of Runway 7. Additional fill may have also been placed south of the haul road and adjacent to the runway in order to eliminate water from ponding in this area. This portion of the wetland is located within the airport's Runway Safety Area and primary surface that extend around the runway to a distance of 500 feet. As previously mentioned, the airport's Runway Safety Area is required to be maintained free of objects on and below the runway surface elevation. It has been noted that during the early 1990's the unnamed tributary located within the alder bog had significant beaver activity and the airport constantly removed debris to prevent clogging of the culvert under the runway. • Based on this information it is likely that the alder bog wetland (Wetland AB) was created as a result of the original airport construction (1968) and was filled during the 1991 runway extension without proper authorization. Per recommendation from the USACE, mitigation for impacts to Wetland AB is proposed at a 1:1 ratio (Table 6: Proposed Mitigation). • -16- Q N 8 3unc 13 - 3NI-IHOIVW ,4 o� 2 p w D� c� 0n � U Z U O CD� p Z Q z Q Z U J O 0 M O i U Z � z O Ii Q F D Z 0�O Q Q�z w o mr�qCD vl CY)F Z o U a-3:wQ 0z�-w 2 w D� c� 0n � U � p w w o.. e~^ o �s v� w� 0 cn ZO�Q Q_ Ln lY Q Q QOz<O 0 JOQ� jEQ_O i I! n N Ii Q' --JD D Z 0�O I Q�z w o vl of z — OZQ� Z o U a-3:wQ 0z�-w _n (n U Li o_: Q'Dxry O r X o_Q-w< iM Ii I` i 2 w D� c� 0n � U e~^ o �s v� w� Q_ Ln w U w QOz<O 0 Q_ i U p Q 3 N a_ N O cn J Q' --JD m w � i s..

Due to the location of each of these pipes, it has been determined that their purpose is to provide access for large mowing equipment at wetland/tributary locations. As previously mentioned, the entire airport property is continuously mowed to maintain a low herbaceous layer. These pipes are corrugated metal (CMP) and have not been identified on any previous permit drawings or USDA historical photographs and therefore have not likely been authorized. It has also been determined that these pipes are not associated with the 2006 fencing project (Figures 7 and 8) since they are not located near the fence. Impacts to stream channels from Pipes #11, #12, and #13 include 60 linear feet (Table 2). Table 2. Equipment Access Culverts • • Pipe tC? Description Culvert Size length (inches).

The airport entrance road bisects the floodplain into two (2) areas identified as the eastern and western floodplains. The following describes findings from the eastern portion of the floodplain during the 2009 investigations. Findings from the western portion of the floodplain are described in Section 3.2. Currently, three (3) ditches parallel to the runway exist throughout the eastern floodplain and have been identified as Ditch 1, 2 and 3 respectively (Figure 8). Ditch 1 is located in the northern portion of the floodplain and is directly adjacent to the existing taxiway constructed in 1994. According to the 1993 Nationwide No. 26 and 401 Water Quality Certification Documentation (Appendix D) this ditch was created as part of the taxiway expansion. Ditch 1 was constructed to collect runoff from the parallel taxiway and outlet into the existing Wetland F/G (Sheet 7 of -18- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application 20, Appendix E) area. As a result, the USACE has determined that Ditch 1 is non- jurisdictional and will not be included in the cumulative wetland impacts. In order to determine the history for the remaining ditches, aerial photographs of the airport property from 1953 and 1980 located at the Macon County NRCS office were reviewed. The 1953 photo depicts the property in agriculture. The 1953 photograph shows two (2) parallel ditches located throughout the agricultural fields (Appendix F). These ditches have been identified as Ditch 2 and Ditch 3 (Figure 8). Ditch 2 is located south of Ditch 1 and Ditch 3 is located south of Ditch 2. Ditch 2 has also been identified on the original airport layout plan developed in 1968 (Appendix 1). As a result, Ditches 2 and 3 were originally created prior to the development of the airport to drain agricultural fields and have been maintained as ditches throughout the change in land use. During the May 2007 agency field view, the USACE and the DWQ observed earthmoving equipment being utilized to maintain these ditches. As a result, the agencies requested that this impact be included in the Runway Extension Permit Application. Additionally, in conversations with Macon County Airport personnel, it was noted that Ditches 2 and 3 have been maintained throughout the years to drain excess water from this area in an attempt to manage ongoing problems with Canada geese. As a result of the ditch locations, the eastern floodplain has been divided into Upper, Middle, and Lower Quadrants for description purposes. The Upper Quadrant (Wetland F/G) is located south of the runway and north of Ditch 2. The Middle Quadrant (Wetland G) refers to the area of the floodplain between Ditches 2 and 3. The Lower Quadrant (Wetlands GA and GB) is south of the Middle Quadrant and borders lotla Creek. Refer to Figure 8 to locate each quadrant of the eastern floodplain. As previously noted, FAA regulations require that areas surrounding the immediate 500 feet of the runway surface or the Object Free Zone be free of objects non- essential for air navigation or aircraft ground maneuvering purposes. This includes standing water to eliminate potential attractants and reduce collisions with wildlife. In addition the general separation criteria for hazardous wildlife attractants on or near airports are 5,000 feet for piston aircraft and 10,000 feet for turbine aircraft. In the past, the airport has attempted to ditch and drain areas for this purpose. In order to effectively address the ongoing problem of standing water specifically located in wetlands adjacent to the runway, the Airport Authority is currently proposing to fill Wetlands F/G, G, GA, and GB, which are all located within the 500 foot radius of the Object Free Zone (Figure 8). The following sections describe wetlands located within the eastern floodplain that will be impacted in order to maintain this portion of the eastern floodplain in compliance with FAA safety regulations. 2.6.4.1 Upper Quadrant (Wetland F/G) Wetland F/G was delineated during the 2007 wetland investigation and is located in the Upper Quadrant of the eastern floodplain. Wetland F/G was identified as a palustrine emergent and scrub shrub system. This wetland is adjacent to lotla Creek (RPW). NWI mapping shows this wetland as -19- February 2009 (Revised October 2009) Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application • Palustrine scrub -shrub, broad-leaved deciduous temporality flooded and partially drained or ditched system (PSS1Ad). • • Dominant vegetation observed during the 2007 wetland delineation included soft rush, New York ironweed (Vernonia noveboracensis, FAC+), jewel weed (Impatiens capensis, FACW), three-way sedge (Dulichium arundinaceum, OBL), cardinal flower, (Lobelia cardinalis, FACW+), woolgrass (Scirpus cyperinus, OBL), blue vervain (Verbena hastata, FAC), dotted smartweed (Polygonum punctatum, FACW+) swamp rose mallow (Hibiscus moscheutos, OBL), blackberry (Rubus arugtus, FACU), cattail (Typha latiflolia, OBL), and peppermint shrub (Mentha piperita, FACW). Soils were black (5 Y 2.5 / 1) clay loam within the upper eight inches. Soil saturation was observed within the upper six inches of the profile. According to the 1993 Nationwide No. 26 and 401 Water Quality Certification documentation (Appendix D), 0.76 acre of this wetland described as a shrub/ herbaceous wetland, was permitted to be filled and is now the existing taxiway and apron area. A network of eight (8) ditches perpendicular to runway have been identified in the northernmost portion of Wetland F/G. Based on aerial photos from 1953 (Appendix F), at least one (1) perpendicular ditch was located in this area at that time. Additional ditching has occurred in this View of Wetland FIG facing west (taken on 8-22- 2007). area between April 1, 1998 and July 27, 2005 (Google Earth aerial photos www. earth. google.com). These ditches were created in an effort to remove standing water from this area and eliminate waterfowl habitat near the runway. 2.6.4.2 Middle Quadrant (Wetland G) Wetland G is located in the Middle Quadrant and is also adjacent to lotla Creek. This wetland was delineated in 2009 as an "atypical" wetland due to the lack of positive evidence of the three parameters utilized to identify and delineate wetlands (Figure 8). As a result, the USACE requested that this area be reviewed to determine a hydric soils boundary since wetland hydrology and hydrophytic vegetation cannot be positively identified. -20- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • During the initial soils investigation on April 16, 2009, four soil profiles were reviewed within Wetland G. At that time only one soil profile (DP -5) contained hydric indicators within Wetland G. Soils observed in DP -5 were dark grayish brown (10YR 4/2) loam with 4 percent of fine dark yellowish brown (10 YR 4/6) mottles from 0-7 inches. Standing water was observed in low spots, but could not be determined as wetland hydrology since the investigation was performed prior to the growing season. Fescue and soft rush were observed as dominant species. Based on this information, the USACE requested an additional investigation of this area to delineate further the limits of hydric soil indicators. On September 2, 2009, a supplemental soils investigation was performed by the LSS (Appendix Q. A hydric soils boundary was determined and flagged on the ground and surveyed. The new boundary parallels the ditches and is an approximate east -west orientation, with the wetter soils to the north toward the runway and ditch 2, and dryer soils to the south near lotla Creek. Vegetation within the new boundary primarily consisted of barnyard grass (Echinochloa crusgalli, FACW-), straw-colored flatsedge (Cyperus stigosus, FACW), broomsedge, golden rod (Solidago canadensis, FACU), and elderberry (Sambucus canadensis, FACW). • • Because of the atypical characteristics of Wetland G, the USACE is requiring that the Airport Authority mitigate for un -permitted ditching which was observed by regulatory personal during May of 2007. Historical photos from the NRCS office provide evidence that the surrounding ditches (Ditches 2 and 3; Figures 3 and 8) have been in existence since 1953 (Appendix F) when the property was utilized for agriculture. Therefore this area has been continually ditched and drained since that time. However the View of Wetland G taken on 3-12-09. USACE has indicated that no evidence exists to determine if the dimensions of the ditches have changed since 1953. Any changes to the former agricultural ditches are considered wetland impacts by the USACE. As a result of having no positive evidence regarding past ditch dimensions and the observed ditching activities that took place in 2007 by regulatory personal, the USACE will assume that there have been alterations to the ditches and considers the atypical characteristics of Wetland G an impact. -21- February 2009 (Revised October 2009) Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application • The USACE currently views the 1991 Jurisdictional Determination (JD) as the most recent authorization on the property and has determined that the 1991 JD will be utilized to measure the amount of impact to the lower portion of Wetland G. As a result, previous impacts to Wetland G have been calculated at 0.43 acre (Figure 8). The 1991 JD boundary has been superimposed on the permit drawings for the area of Wetland G only (Figures 3 and 8). P--� • 2.6.4.3 Wetland GA Wetland GA is located in a topographical depression south of Wetland G in the eastern floodplain and is adjacent to lotla Creek. Soils observed were a brown 00YR 4/3) loam from 0 to 8 inches. Soils from 8 to 15 inches were clay loam and contained a grayish brown (2.5Y 5/2) matrix with 2 percent of coarse red (2.5 YR 4/8) mottles. Soils below 15 inches were clay loam and contained a very dark gray (2.5Y 3/1) matrix with 2 View of Wetland GA taken on 3-12-2009. percent of fine red (2.5YR 4/8) mottles. Fescue and soft rush were the dominant species. Soils were saturated within the upper 12 inches of the profile. Wetland GA has likely resulted from the continual compaction of soils from mechanized maintenance practices which reduces surface infiltration, and enhances ponding within shallow depressions. 2.6.4.4 Wetland GB Wetland GB is located west of Wetland GA in the eastern floodplain. Soils were brown (IOYR 4/3) loam from 0 to 8 inches. Soils from 8 to 12 inches were dark gray (10YR 4/1) clay loam with 7 percent of fine strong brown (7.5 YR 5/8) mottles. Fescue and soft rush were the dominant species. Wetland GB has also likely resulted from continual compacts of soils resulting from -22- View of Wetland GIB taken on 4-15-09. February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • mechanized maintenance practices. Through discussions and various field views with the USACE, Wetlands F/G Wetland G, Wetland GA, and Wetland GB are considered fair quality wetlands and mitigation is proposed a ratio of 1:1 for impacts (Table 6: Proposed Mitigation). 2.6.4.5 1993 / 1994 Onsite Wetland Mitigation Areas According to the 1993 permit documentation, the proposed taxiway construction resulted in losses to approximately 1.88 acres of waters and wetlands of the U.S. (Appendix D). Compensatory mitigation at that time included onsite creation of waters and wetlands within the floodplain. Of the four (4) mitigation areas described in the 1993 permit documentation (Appendix D), three (3) have been identified as non-functioning wetlands that do not meet the three parameter wetland criteria described in the 1987 manual. These areas include two former sedimentation basins that were to be converted into wetlands following the construction of the taxiway and an area of prior converted farmland located centrally in the eastern floodplain. These areas are called out as the 1993 Non -Functioning Wetland Mitigation Locations on Figures 3 & 8. The non-functioning mitigation areas are described in bullets A, C, and D of the 1993 mitigation plan (Appendix D). • During an on site visit with the DWQ on March 11, 2009, these wetland mitigation areas were noted as unsuccessful and did not contain wetland characteristics, specifically vegetation and hydrology. Soil borings within these areas (observed on 03-12-09) typically indicated hydric soil conditions below 20 inches of the surface. • One non-functioning mitigation boundary overlaps with the existing Wetland F/G boundary (Figures 3 and 8). Approximately 0.05 acres of this mitigation location has been identified within the boundaries of Wetland F/G and is considered functioning. Based on recent discussions with the USACE (September 8, 2009) the non- functioning wetland mitigation areas will require compensatory mitigation. The USACE suggested that these areas be mitigated at a ratio of 1:1. As a result, the non-functioning 1993 mitigation sites have been included in the project's cumulative impact totals (Table 5). -23- w I a- O E N m z O Z z z cn 0 z 0 U N m W m p Q Q p U Doo � 0Li p Z i 10 m cn L-I 0 cn w _ a_ N J �l x U O w W U L U U -o Q U OLLJ \ w \� DUpU C) LJ Q C'1 p (n i Z p :2 0 w Q � W �J�( pJUO p ~ Cy W fir\ =WQ H Z w W Q m (7 Z V) X W �- F-- 0(-) Z W D �O Qm W a Of Q = J Q � Z O m U_ pW p ~ cn U O Q D pI\ WLL - O"; p (n U QLLC��Q'I O Q N mW D ' \ N a L aunoizi - 3NIIHOiVW I Lr) W W p Q Q p > Doo z U Q a--) < i 10 m cn z Q O Z Do�w J cn Z ~ O N 2 v p N ON ��. x U O w W own C� U -o Q U OLLJ JUU w � Q Qcr Z 0- NU C) O or� D U H of Z Z ` :2 0 a- — ~ w Zof (/) Q Z Ld Z o0 �� DZ Q )- ~ �- W Z Y u n CD U Q Q V Of � Q Z o J ZZ�3�== O D E X Q Of u z Z� O O O p U W LLI cl� ow J J o m m O U — p Q a Q (n z a L LI a pI\ WLL - O"; p (n U QLLC��Q'I O Q N mW D ' \ N a L aunoizi - 3NIIHOiVW I Lr) W $ p Q Q p > cn J z U Q a--) < i 10 m cn z Q O Z Do�w J 0- N `\ Z ~ � O Q N 2 v p N ON ��.

The purpose of this project was to place an eight foot tall chain link fence around the airport perimeter in order secure the airport from transient wildlife and unauthorized individuals. Construction of this project took place during April of 2006. According to the Fencing Plans (Sheet 6 of 7), the fence detail at ditch crossings illustrates a series of barbed wire extending the width of the stream channel supported by aluminum alloy stakes placed within the streambed. No details for the installation of culverts were identified on the fencing plan drawings. In discussions with the airport designers, it was noted that culvert installations at stream channel crossings would not be incorporated into an airport fencing project because the site would still be accessible through the culverts. However, in discussions with Airport personnel it was later determined that culverts were installed at the time of the fencing project. A description of all stream channels located throughout the property is located in Appendix A (jurisdictional Request letter). Additionally, Table 3: Perimeter Fence Impact Table lists all impacted stream channel locations resulting from the fencing project. Refer to Figures 3, 7, and 8 to locate each impacted stream channel. Table 3.

These concerns were investigated and no previous or proposed impacts have been identified with the following areas. -26- • February 2009 (Revised October 2009) 3.1 Wetland A Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application Wetland A was identified in 2007 along the southeastern fence line within a ° maintained fescue dominant area. This " system was identified as a palustrine emergent wetland adjacent to lotla Creek's �I (R PW). Dominant vegetation included spike rush (Eleocharis, OBL) and smartweed. Soils from 0 to 8 inches were , very dark grayish brown (10 YR 3/2) clay View of Wetland A taken on 8-22-07. loam with 20% of strong brown (7.5 YR 5/8) mottles. Soils below 8 inches were very dark gray (10 YR 3/1) clay loam with 30% of brownish yellow (10 YR 6/8) mottles. Soils were saturated within the upper 12 inches. A small section of a 6 -inch corrugated 'u.m t_" plastic pipe was observed from the edge of this wetland system during the May 2007 inter -agency site visit and during the August 2007 wetland investigation. The USACE questioned the purpose of this pipe and the possibility of it being placed in the `- wetland as a result of the perimeter fence. i To further investigate the purpose of the identified pipe near Wetland A, construction plans from various projects View of Wetland A taken on 2-24-2009. that have occurred on the property since 1968 were reviewed. Construction plans for the Macon County Airport Parallel Taxiway -Aircraft Ramp-Helipad (Sheet 1 of 20, Appendix E) shows a temporary construction entrance in the area identified as Wetland A. The construction entrance detail calls out a temporary 30 -foot long 15 -inch corrugated metal pipe to be installed within this area. This is located in the approximate area of the corrugated plastic pipe identified during the 2007 wetland delineation and USACE site visit. The 1991 wetland delineation drawing does not indicate that wetlands existed in this area at that time (Appendix H). Additionally, in review of construction plans for the Macon County Airport Parallel Taxiway -Aircraft Ramp-Helipad, this area may have been selected as a temporary construction entrance in order to avoid additional wetland impacts. As a result, Wetland A was likely created by the development of the temporary construction entrance for the parallel taxiway project. During an onsite inspection on February 24, 2009, the pipe in this location . appeared to be non-functioning. This pipe was noted as damaged and possibility by a mower. As previously noted, this location is continually mowed due to the -27- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • proximity of the runway. Standing water was observed in the area of Wetland A with the pipe above the wetland elevation. An exit for the pipe was not found in either the road-side ditch or near Tributary B. Additional pieces of the same type of pipe were observed on the ground near Tributary B (Figure 7) and appeared to have been removed or damaged from the mowing. Based on these findings, it is possible that the observed pipe was a remnant from the temporary construction entrance during the 1994 taxiway construction project and was never properly removed. No impacts have been identified or are currently proposed within this area. 3.2 Western Floodplain As previously mentioned, in order to address DWQ concerns regarding the floodplain, a LSS performed an onsite investigation within the floodplain on April 16, 2009 to identify potential fill material. No evidence of fill was found in this area. However, additional areas of hydric soils were identified and delineated within the western floodplain during the 2009 investigations resulting in an expansion of the 2007 Wetland C/D boundary. The 2007 Wetland C/D boundary now incorporates the area identified as Wetland J/M. This wetland boundary predominately follows topographic drainage patterns within the floodplain (Figure 7). During the March 2009 wetlands investigation, soils from 0 to 9 inches were dark brown (10YR 3/3) loam with 5 percent of medium dark yellowish brown (10 YR 3/4) mottles. Soils from 9 to 24 inches were black (10 YR 211) silt loam with 5 percent of firm medium dark brown (7.5 YR 3/4) mottles. Fescue and soft rush were observed as dominant species. Standing water was observed in several low spots. Wetlands are shown in this area on the 1993 permit documentation. The 1993 permit and construction drawings indicate that, prior to the 1994 construction of the parallel taxiway, an unnamed tributary of lotla Creek was located within this portion of the floodplain (Figure 7). The taxiway construction resulted in the relocation of this stream channel to the area currently identified as Tributary B. This impact was authorized under the 1993 Section 404 and 401 permit. 4.0 Names and Addresses of Adjoining Property Owners (Block 24) Table 5.

Since that time, several agencies have come forward with their concerns regarding the proposed project. The following Section includes a description of environmental assessment studies prepared for the Environmental Assessment (EA) document that were requested prior to the approval of the EA in addition to comments and concerns expressed by review agencies following the FONSI approval. 5.1 Threatened and Endangered Species Studies in a letter dated August 1, 2000, the US Fish and Wildlife Service (FWS) commented that the construction of the runway may result in the discharge of sediment and or stormwater that could affect listed endangered and or threatened species and requested a biological assessment in addition to an alternatives analysis for the project area (Appendix K). Species of particular concern noted by the FWS included: the spotfin chub (Hybopsis monacha, federally threatened and NC Threatened), the olive darter (Percina squamata, NC special concern), and the spotted darter (Etheostoma maculatum, federal species of concern; http://ecos.fws.gov/species). These species have all been reported in Little Tennessee River north of the study area. Additional species of concern noted by • the FWS included Appalachian elktoe (Alasmidonta raveneliana, federally and NC endangered), little wing pearly mussel (Pegias fabula, federally and NC endangered), and the Rosyside dace (Clinostomus funduloides, not listed). As requested, a biological assessment was performed by L.L. Gaddy, Ph.D of Terra Incognia and Dr. William McLarney on May 20, 2000. Their finding are presented in a document entitled" Endangered Species, Wetlands, and Biotic Communities of the Proposed Expansion Areas of The Macon County Airport, Franklin, North Carolina" located in Appendix K. The study included inventories of endangered species, wetlands, biotic communities, and fish collected in lotla Branch. The results of this study indicated that no state or federally listed endangered or threatened species were found with the 26.62 acre study area. Furthermore, no habitat that could potentially harbor such species occurs within the study area This study concluded that due to the small size and existing sedimentation of both lotla Branch and lotla Creek, the above mentioned endangered and threatened species could not exist is these aquatic environments (Gaddy / McLarney, 2000). This report also indicates that spotfin chub, olive darter, and spotted darter occur in large streams and rivers and have never been found in a stream as small as the lotla Branch or lotla Creek. It is noted that although the spotfin chub was not found in the project area, it does occur downstream from the site. The assessment states that the Appalachian elktoe and little wing pearly mussel were not found in the project area and potential habitat does not exist. The rosyside dace was found in lotla Branch and is known to do poorly in polluted streams. The report states that this • may be an indication that cleaner water species are able migrate up into lotla Branch and lotla Creek. The biological assessment also states that the rosyside dace -31 - February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • may be a subspecies to the smoky dace (Climostomus sp.), a North Carolina special concern species. Additionally, Mr. Gaddy indicated in a letter to the FWS on January 8, 2002, that erosion and sedimentation of lotla Creek during construction could potentially affect spotfin chub and rosyside dace populations in the lotla Creek/ Little Tennessee River drainage (Appendix K). FWS responded to the biological assessment in a January 31, 2002 letter (Appendix K). This letter stated that FWS expects "... that construction related to the runway extension may result in the discharge of sediment and/or stormwater that could affect the listed species, their habitat, and/or designated critical habitat." FWS added that "the proposed culvert extension and based drainage could certainly result in the discharge of sediment and potential changes in stream function and the sediment discharge could result in a modification of endangered species habitat and could directly affect the spawning and filtering activities of mussels." Though information provided by Mr. Gaddy addressed concerns regarding direct impacts to federally endangered and threatened species, indirect impacts to listed aquatic species continue to be a concern of FWS. An additional letter dated March 20, 2002, from FWS stated that they concurred with the conclusion that Alternative A of the Alternatives Analysis will have the least impact on property included in Section 4(f) of the US Department of Transportation Act (Refer to Appendix K for the Alternatives Analysis). FWS also stated that this alternative, though it will have stream impacts, also appears to be the least environmentally damaging of the action alternatives presented. This letter was perceived by the applicant (Airport Authority) to be a concurrence document from the FWS. However, after the FAA issued the FONSI, the FWS verbally informed W.K. Dickson and stated that they that they do not concur with the proposed project because of outstanding issues that were not addressed. In order to address these concerns the FWS requested information on the erosion and sedimentation control plan that will be put into place during the construction of the project. Refer to Section 5.3 Stormwater Management Plan. Additionally, FWS requested that the Tennessee Valley Authority (TVA) be contacted regarding this project. As a result, a Section 26a Shoreline Construction Permit application to the Tennessee Valley Authority has also been submitted. 5.2 Secondary Impacts During an interagency meeting on April 1, 2009, the FWS stated again that their main concern is negative impacts to downstream water quality, specifically stormwater that could affect the listed species downstream of the project area. The FWS requested design information that supports how the proposed hydrology will actually slow/detain the stormwater runoff rate compared to the current hydrology. Refer to Section 5.3 Stormwater Management Plan. • Additionally the FWS requested information on the use of de-icing chemicals during airport operations. De-icing chemicals are not used the Macon County Airport. Winter operations at the Macon County Airport are strictly tied to existing weather -32- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application conditions. General aviation airports are not designed or built to use any de-icing chemicals that are used at a commercial airport. During winter precipitation, the airport is simply not in use until the weather improves. Additionally, the airport does not use any salt or de-icing chemicals on its pavements. The North Carolina Wildlife Resource Commission (WRC) also requested to review the stormwater management plan and culvert details during an additional interagency meeting on May 6, 2009. Following this meeting, the WRC made recommendations on culvert baffling for the connections to the state road culvert (S.R. 1434), specifically if the design calls for dual concrete culvert sections. WRC indicated that putting alternating baffle plates between the culvert sections in the lower elevation base barrel would be possible without modifying or drilling the culvert sections and can be done as the culvert sections are installed. 5.3 Stormwater Management Plan As a result of the FWS and WRC concerns, the stormwater management plan for the runway, taxiway, and RSA has been developed to ensure no negative downstream impacts. Prior to the runway development, hydrology from lotla Branch and Wetland 1 must continue to be conveyed from the north side of the project under both the runway and taxiway and then connect to the existing culvert that passes under Airport Road (SR 1434). • Multiple options were reviewed to convey flow through the airport. These options included the placement of culverts under the runway and taxiways with open concrete ditches in the infield areas and a variety of pipe combinations including single and multiple pipe alternatives. Given the design changes that have occurred during the course of the project (including raising the profile of the runway and extended RSA to minimize archeological impacts with no excavation for construction on the west side of lotla Branch; Section 5.4), the alternative using open concrete channels with culverts became impractical. This is due to the raised runway profile, which also raises the surrounding safety area, increasing the vertical separation between the pavement and finished ground surfaces and the pipe flow lines, thereby preventing any open channels. As a result, it was determined that first two sections' of pipe would be conveyed through one 72 inch RCP pipe followed by a third section of double 60 inch pipes to match the existing conditions under Airport Road with a double 60 inch culvert (Figure 4). All of the proposed pipes are designed to be installed at a flatter slope than the existing roadway culvert in order to reduce water velocities in the pipe system and keep the existing culvert outfall as the controlling part of the system. Recently, the NCDOT has replaced the roadway culvert pipes (S.R. 1434) due to problems resulting from a perched system and base flow moving through both pipes. • According to design calculations, the increase in runoff resulting from added impervious area is extremely small compared to the existing runoff flowing through the project area on the airport. The 10-year design storm pre-construction ' A section of pipe refers to the length of the pipe between manholes or end sections. -33- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • conditions for the site generates a peak runoff of 38.22 cubic feet per second (cfs) and the post-construction conditions for the site will generate a peak runoff of 49.26 cfs. The existing flow through the dual 60 inch RCP culvert is 237.28 cfs with the east side pipe passing 120.64 cfs at a velocity of 17.06 fps. The post-developed condition would result in the existing east side pipe passing 126.16 cfs at a velocity of 17.27 fps. The resulting change in velocity is 0.21 fps, which is an increase of 1.23 percent from the pre-developed condition. The increased runoff of 11.04 cfs will be controlled by installing underground detention areas in the infield between the runway and taxiway safety areas. The pre-construction conditions stay the same while the post-construction is reduced to 38.07 cfs resulting in a net decrease in flow of 0.15 cfs during a 10-year storm event through the use of underground detention. The use of an underground system was required because above ground storage of water in the infield area between the runway and taxiway is a safety hazard to aircraft and to the airport. The water quality of the new impervious runoff will be addressed with periodical sweeping of the new pavement surfaces and grass swales in the infield and on the north side of the runway. Additionally the required grading of the runway and taxiway safety areas and shoulders will also allow any runoff from the pavement to be filtered through hundreds of feet prior to collection in the proposed pipe network discharge from the site. On August 3, 2009 WK Dickson & Co., Inc. met with FWS to discuss the conceptual stormwater plan. In addition, conceptual plans have also been sent to the WRC for their review. As a result of the proposed culvert design and underground detention, the FWS verbally stated that they would give the project a finding of no significant impact with these modifications to the plans. The FWS also requested that a monitoring plan be developed to ensure no negative impacts downstream. 5.4 Archaeological Studies and Findings Various archaeological studies have been performed at the Macon County Airport dating back to 1965. Throughout each of these studies, findings concluded that Cherokee artifacts and burial sites exist within airport property. Prior to the current investigation, the most recent archaeological study was performed by The Chicora Foundation, Inc. (Chicora) during 2000. The Chicora study indicated that the field west of lotla Branch (the proposed runway extension area) contains a wide variety of data sets, including a large number of human burials, the presence of postholes which likely reveal house patterns, and cultural remains including pottery, cut mica, stone tools, and historic artifacts (Archaeological Testing of 31MA77 Proposed Macon County Airport Expansion, Appendix Q. The North Carolina Department of Cultural Resources State Historic Preservation Office (SHPO) was notified and concurred with these findings. In response to these findings, a Memorandum of Agreement (MOA) was developed • between the State Historic Preservation Office (SHPO), the FAA, the Macon County Airport Authority, the Eastern Band of Cherokee Indians Tribal Historic Preservation -34- February 2009 (Revised October 2009) Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application • Office (EBCI THPO) and United Keetoowah Band of Cherokee Indians in Oklahoma (UKB) in order to seek ways to avoid, minimize, and mitigate adverse impacts from the proposed project. Upon the request of the EBCI THPO, the runway extension was redesigned to minimize archaeological impacts to the maximum extent possible. The original design included the runway extension, associated runway safety area and taxiway continuing on the existing runway gradient. This would have required excavation into the adjacent hillside to reach the required runway elevation and would have possibly resulted in disturbing features or artifacts. The redesign adjusted the proposed runway gradient (or vertical alignment) which includes filling rather than cutting the vertical alignment and allows the extension to be constructed with approximately 115,000 cubic yards of fill thus minimizing the impact to the existing soil and associated archaeological resources contained within the proposed runway extension footprint. The scope of work outlined in the MOA includes a data recovery plan that focused on 25 percent of the proposed runway extension footprint. The goal of the data recovery plan was to describe the people who were buried at this site, to characterize and explain any skeletal traits, pathologies or anomalies of the people and to provide information concerning the lifestyles and histories of the people (Appendix M). The MOA issued on July 15, 2008 was signed by the FAA, SHPO, the Airport Authority, and the NC DOT. The EBCI THPO, and UKB did not sign the MOA. • The survey work included in the data recovery plan began during February of 2009 without the signatures from the EBCI THPO, and UKB. Following this, the EBCI THPO, UKB, and members of the public, expressed disapproval of the recovery plan. Relevant stakeholders met again in 2009 to finalize a decision on the archaeological recovery plan. As a result, the Airport Authority agreed to do 100 percent stripping and mapping of the area included in the footprint of the project. The expanded archaeological investigation now includes stripping the entire footprint of the proposed runway extension area of topsoil. Once this has been completed all features identified during the stripping will be mapped, left in place, and covered up with the removed topsoil or the runway extension fill depending on the timing. This process will preserve features and or artifacts found in the footprint and will eliminate potential disturbances from the runway extension project. Once the project is completed, the features or artifacts identified will be encapsulated underneath the runway extension. As a result of these additional measures, all stakeholders have provided verbal agreement to the archaeological recovery plan. Currently, there is no new or amended MOA. Copies of consultation meeting minutes between all stakeholders are included in Appendix M. 6.0 Alternatives Analysis In designing the runway extension, alternatives were reviewed prior to selecting the • proposed project area. Refer to Appendix N "Alternatives Analysis" for detailed descriptions and illustrations. The alternatives considered for this portion of the project included: -35- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • • Alternative A: Extending Runway 7 by 600 feet to the west (the preferred alternative); • Alternative B: Extending the Runway 25 by 600 feet. to the east; • Alternative C: Extending both runway ends by 300 feet; • Alternative D: Improving Runway Safety Area (RSA) without lengthening runway pavement and; • Alternative E: No action. This analysis determined that no alternative is without impacts. Many of the considered alternatives raised concerns regarding significant wetland and stream impacts, mountainous terrain, additional archaeological testing, property acquisition, and not meeting additional departure and stopping distance requirements for aircraft. The proposed project location (Alternative A) was selected based on the least amount of adverse impacts while meeting the overall project goals. Although the proposed runway extension location will have unavoidable impacts to lotla Branch, wetlands, and archaeology; these impacts are the least extensive and will be appropriately mitigated. Currently, this portion of the property is grass-dominated pastureland that will not require extensive removal of woodland habitat. Additionally, the Macon County Airport Authority owns this property, which will eliminate the need for additional property acquisition. The intention of this alternative is to improve the safety at the airport and bring the runway and runway safety areas up to current FAA standards for the aircraft currently operating at the airport. 0 7.0 Prior Project History The original runway at the Macon County Airport was 3,800 feet long and built in June of 1968. This resulted in culverts being installed in what is currently identified as the upstream reaches of Tributary B and Tributary 1 (Refer to Appendix I: 1968 Airport Layout Plan). An additional culvert was installed beneath the runway near the eastern Runway 25 end to drain a low point created by the runway embankment. This development was performed prior to the enactment of the 1972 Clean Water Act, which is why no permits for the original runway development were found. There are no known COE ID #'s for the last 5 years at the Macon County Airport. A Freedom of Information Act (FOIA) request was submitted in March of 2009 to the Department of the Army Freedom of Information Act Office in order to locate any documentation relating to past development of the runway and taxiway at the Macon County Airport. During that time, DWQ was able to retrieve copies of permits issued by the USACE and NCDEHNR in 1993 for the Parallel Taxiway-Aircraft Ramp-Helipad project (Appendix D). The same permit documentation was also located by the Department of the Army FIOA Willington office in March 2009. This permit information included a Nationwide 26 Permit authorized by the USACE on August 31, 1993 (Action ID No. 199303935) and a 401 Water Quality Certification authorized by the NCDEHNR on July 26, 1993 (DEM Project #93501) for the placement of fill material in 1.88 acres of wetlands or waters in conjunction with the development of a new parallel taxiway, aircraft parking ramp expansion, and a new helicopter parking pad in accordance with FAA design • requirements. Additionally, mitigation for all unavoidable losses was to be conducted onsite in accordance with the plan entitled "Macon County Airport, Phase II Construction -36- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • Proposed Mitigation Plan for Unavoidable Impacts". The Asheville regulatory office was to be informed when the mitigation work began and three annual monitoring reports were to be submitted. The DEHNR 401 water quality certification also states that the mitigation was to include three annual monitoring reports and as-built mitigation plans. These as-built plans and monitoring reports have not been located. Field observations indicate that the mitigation plan outlined in the 1993 permit application was likely followed and completed as specified. No special protection requirements such as a deed restriction or conservation easements were specified in either permit documents. In order to verify this, the Macon County Tax Office has performed several extensive reviews of all property deeds recorded since 1993. A property transaction between Macon County and the Macon County Airport Authority occurred in 2002. This transaction included Macon County transferring all of the airport property to the Airport Authority. According to this document, there is neither record of a deed restriction or conservation easement on wetland mitigation areas nor any mention of wetland mitigation on the property (Appendix J). As requested by the USACE and the DWQ, the 1993 mitigation sites have been identified on the permit drawings (Figures 7 and 8). As previously mentioned , the Airport Authority is proposing to mitigate for the non-functioning 1993 wetland mitigation sites at a 1:1 ratio per recommendation of the USACE. 8.0 Proposed Mitigation 8.1 Avoidance and Minimization Measures • The designers of this project performed an alternatives analysis (Appendix N) in order to determine ways to avoid and minimize potential impacts to waters and wetlands, and archeological artifacts. Although, no alternative is without consequence, the location of the proposed runway extension is an area with the least amount of unavoidable impacts while meeting the project goals. During project discussions with EBCI THPO and UKB, it was requested that the archaeological impacts be minimized. As a result, the proposed grades of the runway extension were adjusted and a complete redesign of the project was performed. The redesign of the runway extension created a new runway profile for the Runway 7 end that required the removal of approximately 500 feet of the existing runway which will be rebuilt to meet the vertical curve requirements for the project. The new profile was designed to be an entire fill project, with no cuts into the existing ground in order to avoid impacts to archaeological features that may possibly be located on the site. Additionally, the runway safety area (RSA) that extends past the end of the paved runway will also be filled in order to tie into exiting ground. A stormwater plan was developed that will eliminate the potential of sedimentation that could affect listed species downstream during and after construction. During construction, the contractor will install erosion control measures including, but not limited to silt fence, rock check dams, temporary diversion ditches, inlet protection, temporary sediment traps, temporary skimmer sediment basins, and a temporary . construction entrance. These measures will be monitored and maintained during construction to minimize any sedimentation from exiting the construction site and shall remain in place until the site has been stabilized. The culvert installations and -37- February 2009 (Revised October 2009) Macon County Airport Authority Runway Extension Project 404, 401 and Section 26a Application 46 underground detention have been designed to slow the stormwater runoff rate coming off the airport property. Post construction measures include periodic sweeping of the new airport pavement to reduce suspended solids prior to reaching the grass shoulders. Grass swales will be installed in grading areas to facilitate sediment attenuation and pollutant removal prior to any stormwater discharge off airport property. 8.2 Restoration of Streams Impacted by Perimeter Fence The Airport Authority is proposing to remove all culverts resulting from the 2006 perimeter fence installation and to restore the stream channels in-kind to their pre- construction condition. The goal of the stream restoration is to convert the altered stream channels and the adjacent riparian zones to a stable condition in order improve water quality functions. The USACE has recommended utilizing the Stream Mitigation Guidelines, April 2003, prepared by the USACE Wilmington District, DWQ, NRSC, U.S. EPA, Region IV, and NCWRC as guidance in developing a restoration plan. The mitigation category selected for the restoration of the impacted stream channels is Enhancement Level II. This includes stabilization of stream banks through sloping to restore the appropriate dimensions and re-vegetation of riparian zones with herbaceous vegetation. As a result, a total of 183.5 linear feet of previously impacted steam channel will be enhanced through these restoration efforts. • The reference reach for the restoration plan is the downstream reach of Tributary B located south of the runway. Tributary B was relocated in 1994 as a result of the taxiway project. During the 2007 wetlands investigation, Tributary B was identified as a second order, perennial stream that flows directly into lotla Creek. This channel is approximately 10 feet wide from top of bank with a channel slope between 2 percent and 4 percent. The bank height averaged approximately 3 feet. View of Tributary 8 taken on 4-16-07. Tributary B is stable in dimension and planform. The riparian zone is dominated by herbaceous vegetation including spike rush, New York Ironweed, jewel weed (Impatiens capensis, FACW), three way sedge, and smartweed. Tributary B is relatively straight with few meanders. Redoximorphic features were observed throughout soils within the stream channel and within the riparian zone along the stream banks. The presence of amphibians was noted during the onsite investigation and evidence of macro invertebrates was observed along the banks including crayfish "chimneys". The restoration plan shall include removal of the culverts and any cover material is placed during the fencing project. Adjustment to the fence shall be made by matching the fence to the channel as specified in the ditch crossing detail located in the Construction Plans for the Security Fencing Project (Appendix G). The channels -38- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • original shape shall be re-graded returning the stream bank to its previous dimensions and will match the existing slope upstream or downstream. Once this has been completed a riparian zone will be disked and prepared for sowing of riparian seed or native grass mixture. The seed mixture will include Mellow Marsh Riparian Buffer Mix or equivalent. Refer to Figure 10 for a list of species included in the permanent seed mixture. Coir matting (or equivalent) will be placed on the stream banks following seeding to aid in germination and stabilization. The restored riparian zones will reduce water velocity and filter pollutants including sediment. The vegetation will only include herbaceous species since the airport is required to regularly maintain low growing vegetation throughout the property. A temporary cover of oat, brown top millet, and or switchgrass will also be used to stabilize the banks until permanent vegetation can become established. r] • -39- KEY IN MATTING PER MANUFACTURERS INSTRUCTIONS COIR FIBER MATTING (400g/m ') STREAM BANK STABILIZATION NOT TO SCALE .

The contractor shall be required to perform all work with equipment from the top of banks outside of the channels to reduce disturbance and possible sedimentation during the channel restoration process.

Noxious weeds or invasive species wi I I be managed as needed. The restoration of the impacted stream channels will occur concurrently with the construction of the runway expansion. As-built channel surveys will be submitted to the USACE and DWQ following completion of the work. The as-built surveys will include the dimensions of the restored channels. 8.2.1 Monitoring • At recommended by the USACE, the restored areas of the stream channels will be monitored for one (1) year and a monitoring report will be submitted to both the DWQ and USACE following the one year of monitoring period. Any problems encountered during the monitoring period will be discussed in the final monitoring report along with recommended remedial actions. According to the Stream Mitigation Guidelines, April 2003, the level of monitoring for this type of enhancement is considered Level 2 and requires documentation of reference photos and a qualitative assessment of plant survival. Photos will be taken at central locations and show both banks from both upstream and downstream views. Photos taken in the winter months will show physical stability. Photos taken in the summer months will document vegetation success. Quarterly (every 3 months or 5 times throughout the year) evaluations of percent cover of perennial herbaceous species will be performed to ensure establishment of the herbaceous community. A plan sheet indicating photo locations will be included with the monitoring report. The success criteria will include at least 75% vegetative cover, no substantial degradation or bank erosion, limited invasion of exotic species, and minimal evidence of down-cutting or deposition. Additionally, the Airport Authority will work with FWS to monitor stream velocity near the culvert outlet of the runway expansion area in order to ensure that the stormwater controls are working as planned. 8.3 Preservation Components n U In compliance with Section 404 mitigation requirements, onsite mitigation options were first considered; however, the FAA and the USACE currently does not support onsite mitigation at the Macon County Airport. On-site preservation, restoration -41- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application is and or creation of wildlife habitat is not encouraged nor accepted as a possible mitigation option by the FAA due to potential collision with avian species. 8.4 NCEEP In-Lieu of Fee (ILF) Mitigation The Macon County Airport Authority has requested to pay into the North Carolina Ecosystem Enhancement Program (NCEEP) In-Lieu of Fee (ILF) program for cumulative impacts associated with the proposed project and past maintenance activities. The Airport Authority is proposing 2:1 and 1:1 mitigation ratios upon recommendations from the USACE (Table 6: Proposed Mitigation). According to the NCEEP letter (Appendix O), NCEEP is willing to accept payment for impacts associated with the Macon County Airport Authority Runway Extension Project and past impacts. Available credits through NCEEP for this project include 3,704 linear feet of stream and 14 acres of riparian wetlands located in the Little Tennessee River Basin (CU# 06010202). Table 6.

Impacts resulting from the runway extension include 749 linear feet to lotla Branch and 0.17 acre to jurisdictional wetlands. Mitigation for the proposed runway -42- February 2009 Macon County Airport Authority (Revised October 2009) Runway Extension Project 404, 401 and Section 26a Application • extension will be provided through payment into the NCEEP ILF mitigation fund. Mitigation for the majority of these impacts is proposed at a ratio of 2:1 by recommendation of the USACE. During this permit application process, research revealed various historic projects remain accountable for impacts not properly permitted. These projects include the filling of 1.38 acres of an alder bog wetland (Wetland AB) during the 1991 runway extension, the installation of 60 feet of un-permitted culverts for mowing equipment access, and un- permitted ditch maintenance of two ditches located in the eastern floodplain after the property changed land use from agriculture to an airport facility in 1968. The USACE is using the 1991 wetland delineation boundaries to determine impacts from ditching. As a result, 0.43 acres has been included in the cumulative impacts for un-permitted ditching. Mitigation for the past impacts will be provided through payment into the NCEEP ILF mitigation fund. Mitigation for previous impacts is proposed at a ratio of 1:1 per recommendation of the USACE. The maintenance of previous agricultural ditches has been performed throughout the history of the airport to maintain the runway in compliance with FAA safety standards. Standing water surrounding the runway has created habitat for waterfowl species putting aircraft at risk for bird air strikes in the past. Instead of continuing to ineffectively maintain the ditches, the Airport Authority is currently proposing the filling and grading of 4.17 acres of wetlands located within the 500 ft. radius of the Object-Free Zone and to reduce airport attractants within 5,000 feet of air operational areas which includes wetlands located in the eastern floodplain (Wetlands F/G, G, GA, and GB). Mitigation for the filling and grading of wetlands located within the airport property will be provided through payment into the NCEEP ILF mitigation fund. Due to the fair quality of these wetlands, mitigation is proposed at a ratio of 1:1 per recommendation of the USACE. Finally, in 1993 the Macon County Airport was issued Section 404 and Section 401 permits for the construction of the parallel taxiway. The permit requirements included the creation of several onsite mitigation locations for compensation of unavoidable impacts. Currently, only one onsite mitigation location is functioning. As a result, the USACE is requiring compensation for the remaining 1.29 acres of non-functioning mitigation areas. Mitigation for the non-functioning wetland mitigation sites will be provided through payment into the NCEEP ILF mitigation fund and is proposed at a ratio of 1:1 per recommendation of the USACE. A total 809 linear feet of stream and 7.01 acres of wetlands have been included in the cumulative impacts of this permit application. Stream restoration of those areas containing un-permitted culverts installed during the 2006 perimeter fence upgrade project will be performed to improve water quality conditions and to more effectively secure the airport property. Monitoring of the restored stream channels and stream velocity into lotla Creek will be performed to ensure stream bank stabilization and no adverse impacts to downstream species. Once permitting, construction, and monitoring have been completed for this project, the Macon County Airport will be in compliance with FAA and NCDOT Division of Aviation safety standards, CWA regulations and Section 26a of the Tennessee Valley Act. • -43- 0 APPENDIX A Revised jurisdictional Wetland Request And Approved jurisdictional Forms 40 0 Fh.WK WDICKSON . community Infrastructure consultants October 1, 2009 Ms. Lori Beckwith U.S. Army Corps of Engineers Wilmington District Asheville, Regulatory Field Office 151 Patton Avenue, Room 208 Asheville, North Carolina 28801-5006 Re: Revised Jurisdictional Determination for the Macon County Airport Authority Runway Extension Project at the Macon County Airport Franklin, Macon County, North Carolina Action ID # SAW 2009-00321 Dear Ms. Beckwith: • On behalf of the Macon County Airport Authority (Owner), WK Dickson & Co., Inc. (Agent) is requesting a jurisdictional determination for the above referenced property because of the proposed runway extension project. Various wetland investigations have been performed throughout the last 2 years at the Macon County Airport. It was found that a number of previous impacts were not properly permitted. These investigations were performed on April 16, 2007, August 22, 2007, March 12, 2009, April 15 & 16, 2009 and September 2, 2009. The entire airport property located within the limits of the perimeter fence has been evaluated for waters and wetlands of the U.S. The results from these investigations are presented herein. Project Information The Macon County Airport is located on Airport Road (NC 1434) northwest of NC Highway 28 in Franklin, Macon County, North Carolina. During each investigation, wetland flags were surveyed by professional land surveyors. Flag numbers and coordinate locations are identified on the attached Wetland Delineation Drawings. Additionally, wetland and upland data sheets and Approved J.D. forms have been completed and are included with this letter. Methods The subject property inspection for wetland boundaries consisted of using a combination of in-house research and field investigations. In-house research included a review of information sources such as the U.S. Geologic Survey 7.5 minute topographic quadrangle for Franklin, North Carolina, aerial photography, National Wetland Inventory Mapping (NWI) and local soil survey.

In-House Research The Macon County Airport property is located in the Little Tennessee River Watershed (HUC # 06010202). The USGS 7.5-minute topographic quadrangle map for Franklin, NC indicates that three tributaries of lotla Creek are located within the investigation areas. The western most tributary is identified as lotla Branch. Refer attached USGS mapping. The remaining unnamed tributaries have been identified and delineated as Tributary B and Tributary 1. The Macon County Airport is located within the lotla Valley of the Smoky Mountains and is currently utilized as a general aviation airport. Seven structures currently exist within the investigation area including; the main terminal, an office, a maintenance hangar, and 4 T-hangar buildings. The surrounding land uses are predominately agriculture and residential. Soils The NRCS Soil Survey for Macon County maps five soils series within the airport property; Dillsboro loam, Udorthents loamy, Braddock clay loam, Toxaway loam, and Hemphill loam. Refer to attached soils mapping. Dillsboro loam (DsB) 2 to 8 percent slopes, is located primarily north of the runway and is rarely flooded. These soils are described by the NRCS as well drained, moderately permeable soils on high stream terraces. 1001 Pinnacle Point ?}Drive, Suite 110 Columbia, SC 29223 Tel. 803-786-426'1 www.wWickson.com Page 2 of 17 North Carolina • South Carolitld . Georgia . Florida • Udorthents (Ud) loamy soil is mapped primarily along entire length of the runway and includes the area of the alder bog wetland (Wetland AB) identified in 1991. According to the soil survey, these soils are areas of cut and fill and are somewhat excessively drained to moderately well-drained. Slope is dominantly 2 to 6 inches, although it ranges from 0 to 10 percent. Permeability is generally slow. Glacial pebbles and fragments of shale and sandstone are common on the soil surface. A seasonal high water table is present in some areas. A very small portion of the airport property is mapped as Braddock clay loam (BkB2) 2 to 8 percent slopes, eroded. These soils are located northwest of the runway. According to the NRCS the Braddock series consists of very deep, well drained, and moderately permeable soils formed in colluvium and alluvium derived dominantly from a mixture of crystalline rocks. They are on footslopes of ridges, colluvial fans, and adjacent high terraces. Toxaway loam JoA), 0 to 2 percent slopes, is frequently flooded. These soils are described by the NRCS as poorly and very poorly drained soils that formed in loamy alluvial deposits near level flood plains of mountain valleys. Toxaway loam is listed on the North Carolina hydric soils list. Toxaway soils are located throughout the floodplain located south of the airport runway and along lotla Branch. Wetlands and waters identified on the airport property are predominately located within areas mapped as Toxaway loam (with the exception of Wetland AB). Hemphill loam 0 to 3 percent slope, rarely flooded is a very poorly drained soil found on low stream terraces. These soils form in alluvium. Hemphill is mapped surrounding the alder bog wetland (Wetland AB) located north of the runway. This soil map unit is on the North Carolina hydric soils list. WETS Table Data and Daily Precipitation WETS Table data was reviewed from the Franklin NC3228 WETS Station, a NWS Cooperative Observer weather station. The WETS data represents data collected from 1971 to 2000. The WETS Table indicates that total average rainfall for Franklin is typically 54.51 inches. A NC DOT/FAA Automated Weather Observing System weather station (K1A5) located at the Macon County Airport, was used as on-site data for this project. According to data retrieved from the Macon County Airport Station, the annual precipitation at the airport in 2007 was 17.56 inches and 18.95 inches in 2008. The WETS Table also indicates that the growing season for Franklin, North Carolina begins on April 17th and continues through the October 19th and is 185 days at a threshold of 28 ° F or higher. According to the 1987 Manual, an area contains wetland hydrology if it is inundated or saturated to the surface continuously for at least 5 percent of the growing season. Therefore, in order for an area at the Macon County Airport to meet wetland hydrology criteria, it would need to be inundated or saturated at a minimum of 9.25 continuous days during the growing season. Drought Conditions • Page 3 of 17 • • Archived records from the North Carolina Drought Management Advisory Council (NCDMAC) documented from January 2000 to April of 2009 were reviewed in order to determine if a change in climatic conditions affected hydrology on the property. NCDMAC classifies drought levels from: • D4- Exceptional Drought • D3- Extreme Drought; • D2- Serve Drought; • D1- Moderate Drought; and • DO -Abnormally Dry. The graph below represents the changes in Macon County drought levels from abnormally dry (0) to exceptional drought (4) during the past 9 years. These records were obtained from www.ncdrought.org/archive. Macon County Drought Levels 2000-2009 II + 1 ?r i Jan-00 _. J.m-04 ];i n-fig ue ® DM Level Drought conditions did not occur between January 2003 and March 2006 and therefore did not receive a drought classification. Macon County experienced the highest levels of drought between April of 2007 and December of 2008 with extreme drought (level 3) and exceptional drought (level 4) classifications. Specifically, Macon County was given a level 4 classification from August 2007 to December 2008. Macon County was downgraded several times to a level 3 within this timeframe, but the majority of months remained at a level 4 classification. At the time of the April 2009 onsite investigations, drought classifications had been downgraded to Moderate Drought (level 1). Changes in climatic conditions likely caused drawdown of groundwater levels below typical conditions. Consequently, wetlands delineated during 2009 likely reflect the improved drought classifications relative to 2007. Background The last jurisdictional determination (J.D.) authorized for waters of the U.S. at the Macon County Airport was issued on July 10, 1991. During 1993, the Macon County Airport submitted an application Page 4 of 17 • for a Section 404 permit and a 401 water quality certification for the construction of a parallel taxiway which resulted in losses to 1.88 acres of wetlands. At that time, a supplementary wetland delineation was performed on the south side of the airstrip; however, this J.D. was never signed by the USACE and has been noted by the USACE as invalid. In March of 2009 the North Carolina Division of Water Quality (DWQ) requested that the floodplain be reviewed for potential fill material because the Airport Authority's 1993 Nationwide 26 permit and associated 401 water quality certification drawings (Appendix D of 2009 IP application) depict large areas of wetlands that were not identified in 2007. A soils investigation was performed by a Licensed Soils Scientist (LSS) on April 16, 2009 to determine if any unauthorized fill of jurisdictional wetlands occurred in the past. The goal of this investigation was to evaluate, characterize, and document the soil and landscape of the eastern floodplain, the western floodplain, and Wetland AB (formerly the alder bog wetland). Additional wetlands were identified and delineated during the LSS investigation. Following the April 2009 LSS investigation, the USACE requested that " Wetland G" be further evaluated due to the non-hydric soil characteristics described in the May 2009 Soil Scientist Investigation. On September 2, 2009, an additional soils investigation of Wetland G was performed in the Middle Quadrant of the Eastern Floodplain. The new wetland boundary for Wetland G is based on hydric soils because hydrology and vegetation can not be positively identified due to past disturbances. Hydric soils determinations were made by utilizing the USDA "Field Indicators of the United States Version 6.0 (2006)". A copy of the LSS report with the supplemental investigation is located in Appendix C of the 2009 Individual Permit Application. Wetland Findings from April 2007 Delineation The April 2007 wetland investigation area only included areas located within the proposed Runway 7 extension (west of the existing runway). lotla Branch and Wetland 1 were both identified and delineated during the initial wetland investigation performed on April 16, 2007. The USACE field verified these aquatic resources as jurisdictional waters and wetlands of the U.S. on May 30, 2007. lotla Branch • lotla Branch is the western most tributary located within the airport property. During onsite investigations, the surrounding landscape of lotla Branch included rolling terrain of grass-covered fields. lotla Branch was identified as a relatively permanent waterway (RPW) and second order stream. Its headwaters are northwest of the airport property. This stream maintains continuous bed and banks throughout the length of the channel and was observed as relatively straight with various meandering bends throughout the length of the Page 5 of 17 View of loda Branch taken on 4-16-07. • reach. Bank width averaged approximately 25 feet and bank height was approximately 7 feet throughout most of the stream channel. The substrate of the streambed consisted of mostly silt and fine sand within the upstream portions. Large particles were also observed within the downstream sections of the reach indicating sedimentation and strong flows. Soil auger borings indicated evidence of redoximorphic features. Soils borings taken along the stream banks were typically dark yellowish brown (10 YR 3/4) silt loam from 0 to 12 inches. From 12 to 18 inches soils were sandy loam with a dark gray (2.5 Y 4/1) matrix and 30 percent of yellowish brown (10 YR 5/6) large and distinct mottles. Wildlife habitat consisted of various leaf packs within bends of the reach and hydrophytic vegetation within the stream channel including soft rush Uuncus effusus FACW+), and bearded sedge (Carex comosa, OBL). Evidence of macro invertebrates was also observed along the banks of the lotla Creek including crayfish "chimneys". Amphibians were also heard during the review of the stream channel. During both onsite visits in April and in August of 2007, lotla Branch maintained continuous flow. Water flows south into lotla Creek (RPW), and eventually into Little Tennessee River; a Traditional Navigable Waterway (TNW). Riparian habitat observed included a dominant shrub layer of tag alder (Alnus serrulata, FACW+). Additional species observed within the riparian corridor included swamp dogwood (Corpus stricta, FACW-) and black willow (Salix nigra, OBL). At the time of the investigation, riparian vegetation along lotla Branch had been cut down and is continually maintained for runway safety purposes. Based on the onsite observations, lotla Branch was identified as a perennial stream channel. Wetland 1 Wetland 1 is a linear palustrine emergent wetland that abuts lotla Branch to the northeast. This wetland is also located within the proposed runway extension area. Due to the shape, it is likely that Wetland 1 was formerly a man-made agricultural ditch that eventually reverted into a wetland community. At the time of the investigation, most vegetation along the wetland boundaries had been mowed. During the onsite investigation, it appeared that black willow and swamp rose (Rosa palustris, OBL) once dominated. Additional vegetation observed included soft rush, spike rush (Eleocharis obtusa, OBL) and sedges (Carex, spp. FACW). Soils from 0 to 12 inches were loam with a dark grayish brown 00 YR 4/2) matrix with many common yellowish red (5YR 5/8) mottles. The wetland data point was collected at flag# 52. The upland soils from 0 toll 2 inches were loam and contained a dark olive brown (2.5 Y 3/3) matrix with 20 percent of red (2.5 YR 5/6) mottles. No hydrologic indicators were observed. Dominant species included red fescue (Festuca rubra, FACU+), white clover (Trifolium repens, FACU) and Queen Anne's lace (Daucus carota, NO. The upland data was collected near flag #52. n t? Page 6 of 17 • Wetland Findings from August 2007 Delineation During the May 2007 USACE field visit, it was requested that additional areas surrounding the terminal building be delineated due to unauthorized earthwork observed in wetlands outside of the runway extension area. The following is a description of these findings. Wetland A Wetland A was identified in 2007 along the southeastern fence line within a maintained fescue dominant area. This system was identified as a palustrine emergent wetland adjacent to lotla Creek (RPW). Dominant vegetation included spike rush (Eleocharis, OBL) and smartweed. Soils from 0 to 8 inches were very dark grayish brown (10 YR 3/2) clay loam with 20% of strong brown (7.5 YR 5/8) mottles. Soils below 8 inches were very dark gray (10 YR 3/1) clay loam with 30% of brownish yellow 00 YR 6/8) mottles. Soils were saturated within the upper 12 inches. A small section of a 6-inch corrugated plastic pipe was observed from the edge of this wetland system during the May 2007 inter-agency site visit and during the August 2007 View of wetland A taken on 8-22-07. Wetland investigation. The USACE questioned the purpose of this pipe and the possibility of it being placed in the wetland as a result of the perimeter fence. To further investigate the purpose of the identified pipe near Wetland A, construction plans from various projects that have occurred on the property since 1968 were reviewed. Construction plans for the Macon County Airport Parallel Taxiway-Aircraft Ramp- Helipad (2009 Section 404 Individual Permit Application, Appendix E) depicts a temporary construction entrance in the area identified as Wetland A. The construction entrance detail calls out a temporary 30 foot long 15-inch corrugated metal pipe to be installed within this area. This is located in the approximate area of the corrugated plastic pipe identified during the 2007 wetland delineation and USACE site visit. The 1991 wetland delineation drawing does not indicate that wetlands existed in this area at that time (Appendix H, 2009 IP Application). Additionally, in review of construction plans for the Macon County Airport Parallel Taxiway-Aircraft Ramp-Helipad, this area may have been selected as a temporary construction entrance in order to avoid wetland impacts. As a result, Wetland A was likely created following the development of the temporary construction entrance for the taxiway project. Additionally, during an onsite inspection on February 24, 2009, the pipe in this location appeared to be non-functioning. This pipe was noted as damaged and possibility by mowing. As previously noted, this location is continually mowed due to the proximity of the runway. Standing water was observed in the area of Wetland A with the pipe above the wetland elevation. An exit for the pipe was not found • Page 7 of 17 • • in either the road-side ditch or near Tributary B. Additional pieces of the same type of pipe were observed on the ground near Tributary B and appeared to have been removed or damaged from the continual mowing. Based on these findings, it is possible that the observed pipe was a remnant from the temporary construction entrance during the 1994 taxiway construction project and was never properly removed. Tributary B Tributary B was identified as a second order stream and RPW that flows directly into lotla Creek (RPW). The upstream reaches of this stream have been piped 40 underneath the existing runway. Additionally, upstream of r _ . the runway, Tributary B flows through wetland AB (the former alder bog wetland identified in 1991). During the 2007 investigation Tributary B was only delineated on the , ,. south side of the runway between two culvert inlets. The bank width averaged approximately 10 feet and bank 44 47 height averaged approximately 3 feet. This channel was observed as relatively straight. Flowing water was observed at the time of the investigation and no leaf litter of JtlimCdly B t,I?e„ ON 4-i0-o,. was present within the stream channel. Redoximorphic features were observed throughout soils within the stream channel and within the emergent wetlands along the stream banks. Soils were a dark grayish brown (10 YR 4/2) sandy loam with 20% of red (2.5 YR 5/6) mottles from 0 to 8 inches. The presence of amphibians was noted during the onsite investigation and evidence of macro invertebrates was observed along the banks including crayfish "chimneys". The riparian habitat of the stream banks included dominant vegetation of spike rush, New York Ironweed (Vernonia noveboarcensis, FAC+), jewel weed (Impatiens capensis, FACW), three way sedge (Dulichium arundinaceum, OBL), and smartweed. Based on the onsite observations, Tributary B was identified as a perennial stream channel. Data for the wetlands surrounding Tributary B was collected at flag #6. The upland soils from 0 to12 inches were loam and contained a dark olive brown (2.5 Y 3/3) matrix. No hydrologic indicators were observed. Dominant species included red fescue, white clover, and Queen Anne's Lace. Upland data was collected near Flag # 6. Wetland C/D Wetland C/D is a linear palustrine emergent system located within the western portion of the floodplain. This wetland is situated at the base of the parking lot berm. Wetland C/D was observed as a jurisdictional wetland that indirectly flows into lotla Creek via OL E t % f??' discharge pipe to a roadside ditch along Airport Road which directly flows into lotla Creek. Aerial mapping shows roadway ditches connecting into lotla Creek south of the airport. Dominant vegetation included spike rush, New York ironweed, jewelweed, three way sedge, duck potato (Sagittaria latifolia, OBL), cardinal flower (Lobelia cardinalis, FACW+), wool grass (Scirpus cyperinus, OBL), blue vervain (Verbena hastata, FAC) and smartweed. Soils from 0 to 6 inches were olive (5 Y 4/4) silty clay loam with no mottles. Soils from 6 to 12 inches were dark gray (5Y 4/1) clay loam with 40 percent of yellowish red (5YR 5/8) mottles. Soils were saturated within the upper 12 inches. Data for the Wetland C/D was collected at flag # C-6. The upland soils from 0 to10 inches were clay loam and contained a dark yellowish brown (10 YR 3/4) matrix. Soils from 10 to 20 inches were dark yellowish brown (10 YR 4/6) loamy sand. Soils below 20 inches contained olive brown (2.5Y 4/3) loamy sand with 20 percent of reddish brown (5 YR 3/4) mottles. No hydrologic indicators were observed. Dominant species included red fescue, white clover, pokeweed (Phytolacca americana, FACU+) and blackberry (Rubus argutus, FACU). Upland data was collected near flag # C-6. Tributary 1 • Tributary 1 is an unnamed tributary of lotla Creek located east of the runway and is identifiable on USGS, NRCS soils, and aerial mapping. This tributary is a first order stream and RPW that flows directly into the lotla Creek. At the time of the investigation, water was observed flowing south toward lotla Creek. Headwaters of Tributary 1 are located north of the airport property. The existing runway and taxiway bisect the stream channel. Continuous banks were observed throughout the length of the stream channel and averaged a width of approximately 12 feet with bank height averaging approximately 6 feet. Tributary 1 was predominately straight throughout the length of the reach and relatively incised with little vegetation stabilizing the banks. The stream banks were highly eroded due to the lack of vegetation. Scoured areas along the stream bank were noted throughout the length of the stream channel. The substrate consisted of larger coarser material including larger pieces of gravel. Upland soils were noted along the stream banks. Based on the onsite observations, Tributary 1 was identified as a perennial stream channel. Wetland F/G Wetland F/G is located in the eastern portion of the floodplain. Wetland F/G was identified as a palustrine emergent and scrub shrub system. This wetland is adjacent to lotla Creek (RPW). NWI mapping shows this wetland as palustrine scrub-shrub, broad-leaved deciduous temporality flooded and partially drained or ditched system (PSS1Ad). Dominant vegetation observed during the 2007 wetland delineation included soft rush, New York ironweed, jewel weed, three-way • Page 9 of 17 View of Wetland FIG taken on 8-22-2007. • sedge, cardinal flower, wool grass, blue vervain, dotted smartweed, swamp rose mallow (Hibiscus moscheutos, OBL), blackberry, cattail (Typha latiflolia, OBL), and peppermint shrub (Mentha piperita, FACW). Soils were black (5 Y 2.5 / 1) clay loam within the upper eight inches. Soil saturation was observed within the upper six inches of the profile. A network of eight (8) ditches perpendicular to runway were identified in the northernmost portion of Wetland F/G. NRCS aerial photos from 1953 show one (1) perpendicular ditch located in this area at that time. Google Earth aerial photos (www.earth. googIe.corn) from April 1, 1998 and July 27, 2005 show that additional ditching has occurred in Wetland F/G throughout this period (Appendix F of 2009 IP Application). These ditches were likely created in an effort to remove standing water from this area and eliminate waterfowl habitat near the runway. Data for the Wetland F/G was collected at flag #F- 36. The upland soils from 0 to 12 inches were silty loam and contained a very dark brown (7.5 YR 2.5/3) matrix. Soils from 12 to 18 inches were silty clay loam with a black (5 Y 2.5/2) matrix and 20 percent of fine medium reddish yellow (5 YR 6/8) mottles. No hydrologic indicators were observed. Dominant species included fescue, Queen-Anne's Lace, winged sumac (Rhus copallina, NI,) and blackberry. Upland data was collected near flag # 36. • Wetland Finding from 2009 In March of 2009, DWQ met with WK Dickson & Co, Inc. to review an area north of the runway identified in 1991 as an alder bog wetland. The onsite inspection revealed that the former bog had been filled. As a result, DWQ requested that the alder bog wetland located north of the runway be included as an impact in the 2009 individual permit application. DWQ also indicated that the Airport Authority's 1993 Nationwide 26 Permit and associated 401 Water Quality Certification drawings (Appendix D of the 2009 IP Application) depict large areas of wetlands that were not identified in 2007. To address this inconsistency they requested that the floodplain south of the runway be reviewed for potential fill material. As a result, soils throughout the floodplain were evaluated by a Licensed Soils Scientist during March and in April of 2009. No evidence of fill was found within the floodplain; however, additional wetlands were delineated at that time. Floodplain Wetlands 2007 FEMA mapping indicates that the airport property south of the existing runway entirely occupies Flood Hazard Zone AE (formerly 100 Year Floodplain). According to NRCS aerial photos from 1953, the areas identified as floodplain were formerly utilized for agriculture prior to the airport development. Currently the airport entrance road bisects the floodplain into the eastern and western sections. Wetlands G, GA, GB and J/M were identified and delineated within the floodplain during the 2009 investigations. Wetland G (atypical) • Page 10 of 17 • Wetland G abuts Wetland F/G to the south and is located in the eastern portion of the floodplain. Wetland G was initially delineated on April 16, 2009 during the LSS investigation. The boundaries of Wetland G are surrounded by two (2) jurisdictional ditches identified as Ditch 2 and Ditch 3. It was determined by the USACE during the May 6, 2009 onsite field view, that this wetland would be considered "atypical" due to the lack of hydrology potentially resulting from the surrounding ditches. During the April 2009 investigation, water was observed ponding in low spots with soft rush and fescue as the dominant herbaceous layer. Wetland hydrology could not be determined at that time since the growing season had not officially started. During the April 16, 2009 LSS investigation, five (5) soil profiles were reviewed within this area. Only • one profile, DP-5 contained hydric indicators within Wetland G (Refer to Wetland Delineation Drawings). Soils observed in Data Point (DP) 5 were dark grayish brown (10YR 4/2) loam with 4 percent of fine dark yellowish brown (10 YR 4/6) mottles from 0 to 7 inches. The upland data was collected near flag G-4. Soils observed in the upland soil boring were brown (10YR 4/3) silt loam from 0 to 8 inches. Soils from 8 to16 inches were brown (10YR 5/3) loam with 3 percent of coarse strong brown (7.5 YR 4/6) mottles. Soils from 16 to 22 inches were very dark gray (10 YR 3/1) loam with 5 percent of coarse (10YR 5/8) mottles. No hydrology was identified in this portion of the floodplain. Dominant vegetation included fescue, mustard (Brassica NI), and broom sedge (Andropogon virginicus FAC-). Based on this information, the USACE requested an additional investigation of this area to further delineate the limits of hydric soil indicators. On September 2, 2009, a supplemental soils investigation was performed by the LSS (Appendix C of the 2009 IP Application). The soil investigation focused on the development of a finer delineation of the hydric soil boundary. A hydric soils boundary was determined and flagged on the ground and surveyed. A total of 15 boring profiles were evaluated in Wetland G (refer to Wetland Delineation Drawings). The new boundary parallels the ditches in an approximate east-west orientation, with the wetter soils to the north, toward the runway, and dryer soils to the south near lotla Creek. Vegetation within the new boundary primarily consisted of barnyard grass (Echinochloa crusgalli, FACW-), Straw-colored flatsedge (Cyperus stigosus, FACW), broomsedge, golden rod (Solidago canadensis, FACU), and elderberry (Sambucus canadensis, FACW). Wetland GA r1 U Page 1 1 of 17 View of Wetland G taken on 3-12-09. C. Wetland GA is located in a topographical depression south of Wetland G in the eastern floodplain. Soils observed were a brown (1 OYR 4/3) loam from 0 to 8 inches. Soils from 8 to 15 inches were clay loam and contained a grayish brown (2.5Y 5/2) matrix with 2 percent of coarse red (2.5 YR 4/8) mottles. Soils below 15 inches were clay loam and contained a very dark gray (2.5Y 3/1) matrix with 2 percent of fine red (2.5YR 4/8) mottles. Fescue and soft rush were the dominant species. Soils were saturated within the upper 12 inches of the profile. Wetland hydrology could not be determined at that time since the growing season had not officially started. Wetland GA has likely resulted from the View of Wetland GA taken on 3-12-2009. continual compaction of soils from mechanized maintenance practices which reduces surface infiltration, and enhances ponding within shallow depressions. The wetland data point was collected at flag #7. The upland soils from 0 to 15 inches were silt loam and contained a brown (10 YR 3/4) matrix with 5 • percent of fine dark brown (7.5 YR 3/4) mottles. Soils from 15 to 20 inches were silt loam with a dark gray (10 YR 4/1) matrix and 8 percent of fine medium strong brown (7.5 YR 4/6) mottles. Soils from 20 to 27 inches were silt with a dark gray (10 YR 4/1) matrix and 8 percent of fine medium dark brown (7.5 YR 3/4) mottles. No hydrologic indicators were observed. Dominant species included fescue. Upland data was collected at DP- 7. Wetland GB Wetland GB is located west of Wetland GA in the eastern floodplain. Soils were brown (1 OYR 4/3) loam from 0 to 8 inches. Soils from 8 to 12 inches were dark gray (1OYR 4/1) clay loam with 7 percent of fine strong brown (7.5 YR 5/8) mottles. Fescue and soft rush were the dominant species. Wetland GB has also likely resulted from continual compacts of soils resulting from mechanized maintenance practices. Standing water was observed throughout the wetland during the April 2009 investigation. Wetland hydrology could not be determined at that time since the growing season had not officially started. The wetland data point was collected at Flag # 6. The upland soils were sandy clay loam and • Page 12 of 17 View of Wetland G/8 taken on 4-15-2009. • contained a dark brown (10 YR 3/3) matrix with 5 percent of fine dark yellowish brown (10 YR 3/4) mottles from 0 to 7 inches. Soils from 7 to 15 inches were sandy clay loam with a dark gray (10 YR 4/1) matrix and 8 percent of fine dark yellowish brown (10 YR 3/4) mottles. Soils from 15 to 31 inches were silt clay with a black (10 YR 211) matrix and 8 percent of fine medium brown (10 YR 3/4) mottles. No hydrologic indicators were observed. Fescue was the dominant species. The upland data point was collected at DP #9. Wetland J/M Prior to the 1994 taxiway construction, an unnamed tributary of lotla Creek was located within the western portion of the floodplain area. This impact was authorized under the Section 404 and 401 permits issued in 1993. During the 2007 wetland investigation, Wetland C/D was delineated within the western floodplain. During the 2009 investigation, the wetland C/D boundary was expanded to include the area identified with Wetland J/M. Soils located with Wetland J/M were loam with a dark brown (10 YR 3/3) matrix from 0 to 9 inches. Soils below 9 inches were silt loam with a black (10YR 211) matrix and 5 percent of fine medium dark brown (7.5 YR 3/4) mottles. This wetland boundary predominately follows topographic drainage patterns within the floodplain. Dominant species observed included soft rush and fescue. Areas of • standing water were also observed throughout low spots; however, wetland hydrology could not be determined at that time since the growing season had not officially started. The wetland data point for Wetland J/M was collected at DP -2. Upland soils from 0 to 11 inches were dark yellowish brown (10 YR 4/4) loam with 7 percent of coarse very dark gray (5 Y 3/1) mottles and 3 percent of fine strong brown (7.5 YR 5/8) mottles. Soils from 11 to15 inches were very dark grayish brown (10 YR 3/2) silt loam with 2 percent of coarse strong brown (7.5 YR 5/8) mottles. Fescue was the dominant species. No hydrologic indicators were observed. The upland data point was collected between flags J-19 and J-20. Wetland AB The "alder bog" was originally identified and delineated during the 1991 Wetland Delineation. The 1991 Wetland Delineation states that the alder bog was once dominated by alders (Alnus serrulata), red maple, buttonbush, swamp rose, sedges and soft rush. The 1991 report also states that this community was probability created when a small tributary of lotla Creek was partially impounded during the construction of the airport. Refer to Appendix H of the 2009 Section 404 • View of Wetland AB taken on 4-15-2PgRe 13 of 17 • Individual Permit Application for a Copy of the 1991 jurisdiction Delineation. During the April 15, 2009 wetland investigation, this wetland was identified as Wetland AB. Soils from 0 to 3 inches were observed as yellowish red (5 YR 4/6) silt loam with large pieces of gravel. Soils from 3 to 8 inches were very dark grayish brown (2.5 Y 3/2) silt loam with 3 percent of coarse light red (2.5 YR 6/8) mottles. Water was observed at 3 inches below surface. Dominant species included soft rush. Data for Wetland AB is located at the data point AB WET 1. Soils observed from the adjacent upland area were olive brown (2.5 Y 4/4) loam from 0 to12 inches. Soils from 12 to 22 inches were light yellowish brown (2.5 Y 6/4) silt loam with 20 percent of distinct yellowish brown (10 YR 5/6) mottles. The water table was observed at 22 inches. Below 22 inches, soils were olive (5Y 5/4) silty clay loam with many yellowish brown (10 YR 5/8) mottles. Fescue was the dominant species. Upland data was taken at data point AB Upland. The LSS investigation reviewed this area to confirm the presence of fill material. The LSS report states that approximately 6 to 16 inches of fill was identified across most of the former bog and describes that the fill material appears to be local upland soil, most likely from the adjacent hill slope. Background research determined this likely occurred during the most recent runway extension construction in 1991 (2009 IP Application, Appendix Q. Approximately 1.38 acres has been identified as previously • filled and 0.16 has been identified as non-fill during the wetland and soils investigations. Wetland 2 Wetland 2 was delineated during April 2009 maintenance equipment. • and is located east of Wetland 1. This area W was not delineated in any of the previous delineations (1991 and 2007). Wetland 2 is in a topographic depression of a mowed area just north of the end of runway 7. Soils were ? x silt loam with a very dark grayish brown (10 YR 3/2) matrix and 1 percent of coarse brownish yellow (10YR 6/8) mottles from 0 to 10 inches. Soils from 10 to 12 inches were dark olive brown (2.5Y 3/3) clay loam with 3 ,v percent of coarse light olive brown (2.5 Y 5/6) mottles. Water observed within the s ;_. " -,- boring hole was at 11 inches below the surface. Vegetation observed included fescue, mustard, and soft rush. It is likely that Wetland 2 was created through continual soil compaction from use of mechanized The wetland data point was taken near Flag # 6. Page 14 of 17 View of Wetland 2 taken on 4-15-09 • The adjacent upland soils from 0 to 10 inches were brown (IOYR 4/3) silt loam with 5 percent of fine very dark grayish brown (2.5 Y 3/2) mottles. Soils from 10 to 14 were olive brown (2.5 Y4/3) silt loam with 3 percent of coarse dark olive brown (2.5Y 3/3) mottles and 2 percent of medium yellowish brown 0OYR 5/8) mottles. Water was observed at 14 inches below surface. Dominant vegetation included fescue. The upland data point was taken near flag #6. Wetland 3 Wetland 3 is located within a topographic depression west of lotla Branch. This area was not delineated in any of the previous delineations (1991 and 2007). Soils from 0 to 9 inches were a dark brown (10 YR 3/3) loam. Soils from 9 to 10 inches were dark brown silt loam (10 YR 3/3) with 5 percent of brownish yellow (10 YR 6/8) coarse mottles. Soils from 10 to13 inches soils were dark reddish brown (5 YR • 2.5 12) clay loam with 5 percent coarse yellowish red (5 YR 4/6) mottles. Standing water was observed in the auger boring hole at time of investigation. Existing vegetation included soft rush and wool-grass. It is likely that Wetland 3 was also created because of continual compaction of soils through mechanized maintenance of the airport property. The data point was collected at flag #1. View of Wetland 3 taken on 4-15-09. Upland soils from 0 to 8 inches were saturated dark brown (10 YR 3/3) silt loam. Soils from 8 to 13 inches were dark yellowish brown (1OYR 3/4) silty clay loam with 2 percent fine brown (7.5YR 4/4) mottles and no saturation. Soils from 13 to 16 inches were very dark grayish brown (10 YR 3/2) clay loam with 5 to 7 percent of coarse fine brownish yellow (1 OYR 6/8) mottles. Dominant vegetation included fescue and broomsedge. The upland data point was taken near flag #3. Tributary 2 Tributary 2 is located east of Tributary 1 and south of the eastern Runway 25 end. This channel was constructed as a result of the parallel taxiway in 1994 in order to collect runoff generated from the runway and taxiway. Tributary 2 is not identified on USGS, NWI, or soils mapping. is Page 15 of 17 View of Tributary 2 taken on 4-15-09. • Tributary 2 directly flows into lotla Creek southeast of the airport property. Eroding banks were observed throughout the length of the stream channel and averaged a height of 6 feet. The width of the stream channel is approximately 10 feet. The streambed contained a vegetated bottom of sedges and soft rush. Water was observed in the stream channel at the time of the investigation. Based on the onsite observations, Tributary 2 was identified as a jurisdictional stream channel as it directly flows into lotla Creek.

RHA SECTION 10 DETERMINATION OF JURISDICTION. There "Wft "navigable waters of the U.S." within Rivers and Harbors Act (RHA) jurisdiction (as defined by 33 CFR part 329) in the review area. [Required] • Waters subject to the ebb and flow of the tide. Waters are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce. Explain: B. CWA SECTION 404 DETERMINATION OF JURISDICTION. There "waters of the US." within Clean Water Act (CWA) jurisdiction (as defined by 33 CFR part 328) in the review area. [Required] 1. Waters of the U.S. a. Indicate presence of waters of U.S. in review area (check all that apply):' TNWs, including territorial seas Wetlands adjacent to TN Ws Relatively permanent waters2 (RPWs) that flow directly or indirectly into TNWs Non-RPWs that flow directly or indirectly into TNWs Wetlands directly abutting RPWs that flow directly or indirectly into TNWs Wetlands adjacent to but not directly abutting RPWs that flow directly or indirectly into TNWs Wetlands adjacent to non-RPWs that flow directly or indirectly into TNWs Impoundments of jurisdictional waters Isolated (interstate or intrastate) waters, including isolated wetlands b. Identify (estimate) size of waters of the U.S. in the review area: Non-wetland waters: Iotla Branch 835 linear feet: 25 width (ft) and/or 0.37 acres. Wetlands: Wetlandl= 0.11acres; Wetland 2=0.05 acres; and Wetland 3=0.06 acres. c. Limits (boundaries) of jurisdiction based on: Elevation of established OHWM (if known): 2. Non-regulated waters/wetlands (check if applicable):3 Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. • Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. z For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). ' Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs • The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section 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 not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: Drainage area: 1,154: Average annual rainfall: 54.51 inches Average annual snowfall: 7 inches (ii) Physical Characteristics: (a) Relationship with TNW: ? Tributary flows directly into TNW. ® Tributary flows through tributaries before entering TNW. Project waters are 6rver iles from TNW. Project waters are iles from RPW. Project waters are aerial (straight) miles from TNW. Project waters areaerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: • Identify flow route to TN W5: Iotla Branch (RPW) to Iotla Creek (RPW) to Little Tennessee River (TNW). Tributary stream order, if known: second order stream. ' Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. ' Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW. (b) General Tributary Characteristics (check all that apply): Tributary is: ® Natural ? Artificial (man-made). Explain: ? Manipulated (man-altered). Explain: Tributary properties with respect to top of bank (estimate): Average width: 25 feet Average depth: 7 feet Average side slopes: UIC Primary tributary substrate composition (check all that apply): ® Silts ® Sands ? Concrete ® Cobbles ? Gravel ? Muck ? Bedrock ® Vegetation. Type/% cover: FACW/OBL herbaceous instream 15% ? Other. Explain: Tributary condition/stability [e.g., highly eroding, sloughing banks]. Explain: stable banks. Presence of run/riffle/pool complexes. Explain: Presence of riffle pool sequences throughout due to observed flow, woody debris, and deeper pool areas. Tributary geometry: w" Tributary gradient (approximate average slope): 0-2 % (c) Flow: Tributary provides for: Estimate average number of flow events in review area/year Describe flow regime: Perennial. Other information on duration and volume: Surface flow is: Characteristics: Subsurface flow:` Explain findings: • ? Dye (or other) test performed: Tributary has (check all that apply): ® Bed and banks ® OHWM6 (check all indicators that apply): ® clear, natural line impressed on the bank ® the presence of litter and debris ? changes in the character of soil ® destruction of terrestrial vegetation ® shelving ? the presence of wrack line ® vegetation matted down, bent, or absent ? sediment sorting ® leaf litter disturbed or washed away ? scour ® sediment deposition ? multiple observed or predicted flow events ? water staining ? abrupt change in plant community ? other (list): ? Discontinuous OHWM.7 Explain: If factors other than the OHWM were used to determine lateral extent of CWA jurisdiction (check all that apply): High Tide Line indicated by: Mean High Water Mark indicated by: ? oil or scum line along shore objects ? survey to available datum; ? fine shell or debris deposits (foreshore) ? physical markings; ? physical markings/characteristics ? vegetation lines/changes in vegetation types. ? tidal gauges ? other (list): (iii) Chemical Characteristics: Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.). Explain: Water color is typically clear except during rainfall events due to runoff from upstream sediment. Identify specific pollutants, if known: Sediment from surrounding land use (agriculture and residential) and possibly from runway. • "A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break. 'Ibid. (iv) Biological Characteristics. Channel supports (check all that apply): ® Riparian corridor. Characteristics (type, average width): Tag alder, 40 ft. ? Wetland fringe. Characteristics: • ? Habitat for: ? Federally Listed species. Explain findings: ? Fish/spawn areas. Explain findings: ? Other environmentally-sensitive species. Explain findings: ® Aquatic/wildlife diversity.

Characteristics of wetlands adjacent to non-TNW that flow directly or indirectly into TNW (i) Physical Characteristics: (a) General Wetland Characteristics: Properties: Wetland size:Wetland 2= 0.05 Wetland 3= 0.06 acres Wetland type. Explain:Palustrine herbaceous . Wetland quality. Explain: Both Wetland 2 and Wetland 3 are located within depressions along the floodplain that are continually mowed. These wetlands were like created as a result of continual compaction of soils through mechanized maintenance of the airport property which has reduced surface infiltration and enhanced ponding within shallow depressions. Wetlands consider high quality due to adjacency to Iotla Branch. Project wetlands cross or serve as state boundaries. Explain: (b) General Flow Relationship with Non-TNW: Flow is: "Rw `• .

(Y/N) Size (in acres) • Wetland 2 No 0.05 acres Wetland 3 No 0.06 acres Summarize overall biological, chemical and physical functions being performed: Wetlands 2 and 3 function to provide flood attenuation and minimal aquatic habitat. C. SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: . 2.

' Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent': B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section 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 not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C 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.

Identify (estimate) size of waters of the U.S. in the review area: Non-wetland waters: Tributary 1 = 250 linear feet: 12 width (ft) and/or 0.07acres,Tributary 2= 37 linear ft. 10 ft. width or 0.03 Wetlands: Wetland F/G =2.72acres, Wetland G= 0.83 acres, Wetland GA= 0.11 acres, Wetland GB= 0.08 acres. c. Limits (boundaries) of jurisdiction based on Elevation of established OHWM (if known): 2. Non-regulated waters/wetlands (check if applicable)? Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). ' Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.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 III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section 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 waterbodya is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below. 1.

Wetlands provides, flood attenuation, polluant removal, and wildlife habitat. C. SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to . TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:Tributary 2 flows directly into Iotla Creek (RPW). 2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: 3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: There is a significant nexus between Iotla Creek, Tributary I and Wetlands F/G, Wetland G, Wetland GA, and Wetland GB into Little Tennessee River. D. DETERMINATIONS OF JURISDICTIONAL FINDINGS. THE SUBJECT WATERS/WETLANDS ARE (CHECK ALL THAT APPLY): 1. TNWs and Adjacent Wetlands. Check all that apply and provide size estimates in review area: 8 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: Tributary 1 contains continous bed and banks with significant flow during the one of the warmest months of the year. This stream appeared relatively incised with scoured areas along the stream banks. The lack of vegetation • resulted in highly eroded stream banks. This lack of vegetation may also be a result of airport runway maintenance. The substrate consisted of larger coaser material including large pieces of gravel. 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: Provide estimates for jurisdictional waters in the review area (check all that apply): Tributary waters: Tributary I = 250 linear feet 12width (ft). Other non-wetland waters: acres. Identify type(s) of waters: 3. Non-RPWs8 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: Tributary 2= 37 linear feet 10 width (ft). Other non-wetland waters: acres. Identify type(s) of waters: 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 III.B and rationale in Section III.D.2, above. Provide rationale indicating that wetland is directly abutting an RPW: . Provide acreage estimates for jurisdictional wetlands in the review area: acres. 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: 4.17acres. Wetlands adjacent to non-RPWs that flow directly or indirectly into TNWs. 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. Impoundments of jurisdictional waters.' As a general rule, the impoundment of a jurisdictional tributary remains jurisdictional. Demonstrate that impoundment was created from "waters of the U.S.," or Demonstrate that water meets the criteria for one of the categories presented above (1-6), or Demonstrate that water is isolated with a nexus to commerce (see E below). • 'See Footnote # 3.

Lori Beckwith of the US Army Corps of Engineers in the Asheville field office requested additional information requiring field investigation after reviewing the original soils report in conjunction with the 404/401 permit process. A better understanding is needed of the soil characteristics and potential biological and chemical processes occurring in the wetland soils and adjacent areas of Wetland G (Middle Quad). This report further describes the results of this soil evaluation and is part of the original report dated 28 May 2009. Any subsequent transfer of the report by the user shall be made by transferring the complete report, including figures, maps, appendices, all attachments and disclaimers. This report follows Standard of Practice based on the Draft CSSC A-0002- 01. During the site evaluation soil borings were taken throughout the identified areas. Typical soil profile descriptions were recorded (Appendix A). The NRCS guide for identifying and delineating hydric soils Field Indicators of Hydric Soils in the United States (Versions 6) was used to determine if soil meets the status of a wetland soil. Indicators valid for the mountain region, Land Resource Region N, were used. METHODOLOGY • NRCS Soil Mapping A discussion of the mapped soil series, Toxaway, was expanded. This discussion includes the effects of artificial drainage on the soils series and potential changes in the characteristics are covered in this discussion. On Site Soil Investigation Additional soil data was collected on 2 September 2009 in Wetland G. In addition to the previous four soil profiles, an additional 11 borings were described this area. A wetland soil boundary was determined and flagged. Determination of this boundary is based on the Guide to Hydric Soil Indicators NRCS V6.0 and 1987 Wetland Delineation Manual. The boundary and all borings locations were surveyed. RESULTS AND DISCUSSION NRCS Soil Mapping The floodplain is mapped by the NRCS Macon County Soil Survey as Toxaway series soils. This soil is an alluvial soil found along larger stream channels. This soil is classified as a Cumulic Humaquept. Inceptisols are soils that retain a close resemblance of the parent material from which they formed and have not had time to developed adequate profile features diagnostic for other orders or have weak diagnostic features. A Humaquept infers that this soil, in its unaltered state, is not dry for more than three months a year and has started accumulating organic matter in the upper horizons. The cumulic modifier refers to the addition of mineral soils to the surface, such as natural sediment deposition. On Site Soil Investigation • The soil investigation focused on Wetland G and the development of a finer delineation of the hydric soil boundary. In addition to the borings already described, 11 additional Macon County Airport Authority Runway Extension Project Macon County, North Carolina • borings were recorded, resulting in 15 boring profiles in Wetland G (Figure). A hydric soil boundary was determined and flagged on the ground and surveyed. The boundary parallels the ditches is an approximate east-west orientation, with the wetter soils to the north, toward the runway, and dryer soils to the south near lotla Creek. The soil surface overlaying this area was found to have a brownish loamy texture (loam, sandy loam, silty loam, and sandy clay loam). The surface horizons (Al and A2) range from 7 to 19 inches in the wetter areas and from 15 to 17 inches in the dryer areas. Below the surface horizons are Cg horizons. The Cg horizons are similar to the Official Soils Series Description for Toxaway soils. The surface horizons are stratified with brownish sandy and loamy surface material of varying thickness. These cumulic horizons are younger soils exhibiting few diagnostic soil characteristics. They are most likely the result of flooding and sediment deposition events early last century. The soils found in Wetland G are underlain by a black, thick, silty or clayey textured soil high in organic matter. Many areas have developed redoxomorphic features of iron concentrations indicating alternating periods of saturation and drying. These soils fall within the color and texture range defined for the Toxaway series and based upon the findings across this floodplain, the soils appear to meet the range of characteristics of the Toxaway series. The taxonomic name appears to describe adequately the soil system found in Wetland G at this site. • Seven soil profiles were found to have hydric indicators in the upper 12 inches (Table 1). The hydric indicator F3, Depleted Matrix, was the most common indicator. The hydric characteristics observed in the upper 12 inches consist of a low chroma matrix with common to many mottles (redoxomorphic concentrations) found in the Al and A2 horizons. Mottles are found both in the hydric and in the non-hydric soil profiles in the upper horizons. The presence of these mottles is atypical of the Toxaway series and possibly indicates repeated wetting and drying conditions. The ditches promote drainage of this area and provide conditions for repeated aeration needed for oxidation of minerals in these soils. • 2 Macon County Airport Authority Runway Extension Project Macon County, North Carolina • Table 1.

Drainage in these low-lying areas is limited by the lack of slope and the elevation of outlet drains. The soil in Wetland G has a number of areas underlain by clayey textures. These finer materials likely slow internal drainage, allowing somewhat longer saturation periods. Most of the soil profiles recorded indicate various degrees of mottling, providing evidence to support the repeated wetting and drying cycles. Based upon the agricultural and cultivation history of this site, these redoxomorphic mottles have formed since the agricultural activity ceased. The ditches to each side of Wetland G appear to drain effectively surface waters from rain and flooding events and enhance subsurface drainage. CONCLUSIONS The floodplain soil in Wetland G is mapped as alluvial Toxaway series. The soil investigation resulted in a finer delineation of the hydric soil boundary, paralleling the ditches in an approximate east-west orientation. The surface horizons (Al and A2) range from 7 to 19 inches in the wetter areas and from 15 to 17 inches in the dryer areas. Many areas have developed redoxomorphic features of iron concentrations indicating alternating periods of saturation and drying. The cumulic surface horizons exhibit few diagnostic soil characteristics and are most likely the result of flooding and sediment deposition events early last century. The soils are underlain by a black, thick, silty or clayey textured soil high in organic matter. These soils fall within the color and texture range defined for the Toxaway series and based upon the findings across this floodplain, the soils appear to meet the range of characteristics of the Toxaway series. • 3 Macon County Airport Authority Runway Extension Project Macon County, North Carolina • The ditches enhance surface and subsurface drainage, resulting in alternating saturation and drying. Mottles are found both in the hydric and non-hydric soil, indicating various degrees of mottling and provide evidence to support the repeated wetting and drying cycles. Saturation of the soil does persist long enough to form redoxomorphic mottles in many of the profiles. Based upon the agricultural and cultivation history of this site, these redoxomorphic mottles have formed since the agricultural activity ceased. The presence of these mottles is atypical of the Toxaway series and possibly indicates repeated wetting and drying conditions. The ditches promote drainage of this area and provide conditions for repeated aeration needed for oxidation of minerals in these soils. C7 • 4 / r Lnil O' O'.

Dickson; Paul Webb, TRC; Steve Clagett, SHPO; Russell Townsend, EBCI; Tyler Howe, EBCI; Joe Collins, AA Legal Counsel; Teresa McDowell, AA Clerk; and Lisa Favors, FAA; and Dana Perkins, FAA. By Telephone Conference: Lisa Stopp, UKPTHPO; and Kim Amao, FAA Legal Counsel, Southern Region. Mr. Preston starts the meeting by requesting clarification from Russell Townsend regarding the procedure for reporting and consultation regarding any human remains found during data recovery at the Macon County Airport, in the Runway Extension • Project area. Mr. Preston suggests that he will make a formal request for consultation within 24 hours of any human remains being found, with Mr. Townsend as the ECBI representative to respond within 48 hours. Mr. Preston states that he will make his phone number available in the e-mail, and will ask interested parties including Steve Clagett, SHPO, Russell Townsend, EBCI, Lisa Stopp, UKPTHOP, and the Cherokee Nation of Oklahoma to respond to the e-mail by phone. Mr. Townsend suggests that he include an invitation to consult within his e-mail, and state an available time convenient to Mr. Preston for the consult. Mr. Townsend states that there is nothing in the MOA that states that consultation with all parties take place at the same time. Mr. Webb provides an update of the project findings to Ms. Stopp. Mr. Webb reports that they have completed mechanized excavation of 22,000 square feet of the estimated 31,000 square feet necessary to satisfy the MOA, and that they are currently working in the five (5) blocks specified in the scope of work. They are also working within a buffer area which is identified as area 156. Until now, Mr. Webb states that they have uncovered Cherokee materials in the blocks as well as materials extending outside of the blocks in some areas. He also states that they have found an intact structure basis, post patterns, and 17 likely graves, with human remains found in two (2) of those. The human remains were found underneath a filter fabric installed during the 2000 excavation in one instance, and a previously unreported tooth was found in an adjacent area. He also states that there are woodland structure patterns present. He states that he hopes to complete the additional 1.25 acres specified in the scope of work as soon as possible. Ms. Stopp questions why any previously discovered human remains were disturbed again. Mr. • Webb states that the remains have been re-exposed and recovered. He also states that r 1 L_J Macon County Airport Authority Consultation Meeting-3-12-09 Page Two upon observation of the previously unreported tooth, the area was recovered, with nothing being displaced or removed. Mr. Webb also states that he cannot rule out additional discoveries at this time. Mr. Webb states that there are approximately six (6) to eight (8) weeks of work yet to be done. Ms. Stopp expresses concern that her agency was not notified when the actual data recovery work was started. Mr. Preston states that he will review the MOA, and will call her to discuss these concerns. Ms. Stopp also expresses a desire that they be "kept in the loop" with how things are progressing, and that they want to contribute during this process. Mr. Clagett states that the weekly updates provided by the archeologists contain much information which is both informative and detailed, and that these reports will be provided to her. He also states that he will be happy to assist as needed by Ms. Stopp. Mr. Preston asks Mr. Townsend to discuss the procedures regarding the remains in the future. Mr. Townsend states that the EBCI wants all remains left undisturbed in the place where they are found. Mr. Webb states that if any remains are uncovered, they will • immediately recover and if the use of machinery exposes any remains, they will immediately rebury in the area in which they were found. Ms. Stopp asks if they are reburied in the area in which they are found, will that constitute a defined environmentally sensitive area. Mr. Preston states that it will be marked as an environmentally sensitive area, but will not be defined as such. The MOA states that all work is to stop within a 50 feet area upon encountering a clearly defined burial pit, with remains, but Mr. Webb states he would like to continue working in the surrounding area while a decision is made regarding the remains. Mr. Townsend and Ms. Stopp agree that this will be permitted. Mr. Webb states that although the final areas for the remainder of the stripping are to be determined by the contractor, he would welcome the tribes' input. Ms. Stopp states that any recovery should be as non-invasive as possible, and that out of the five (5) sites noted, that the emphasis should be on the areas where the most material can be found. Ms. Stopp also states that they are watching the progress of this project very closely, and suggests that a better line of communication be utilized by all parties. Mr. Preston asks that the reburial procedures be discussed. The reburial procedure involves re-interring the remains currently stored at the SHPO office. He asks who will be the designated archeologist who will travel with the remains from Raleigh to Franklin. Mr. Townsend responds that someone from his office will be available to accompany the remains. In connection with the burial site, Tyler Howe informs Ms. Stopp that he chose the re-burial site, which has good sight within the recovery area, and Ms. Stopp expresses satisfaction with the site. • Ms. Stopp expresses interest in visiting the site, accompanied by Dr. Richard Allen. The travel expenses incurred by them will be the responsibility of the Macon County Airport • Macon County Airport Authority Consultation Meeting-3-12-2009 Page Three Authority. Chairman Gregory states that travel arrangements will be handled in the way that is most convenient for Ms. Stopp and Dr. Allen. Mr. Townsend states that federal per diem is recognized by the Tribe. To recap, Mr. Preston states that upon the finding of human remains, he will contact the required parties by e-mail within 24 hours. Within the body of this e-mail will be stated a convenient time for Mr. Preston to consult with the parties, with the hopes that everyone can be available at that time. He will also provide a contact number. It is not necessary that all parties consult at the same time. At that point, Mr. Townsend assured Mr. Preston that either he or Tyler Howe will be available for consultation. r? U 0 0 Consultation Meeting - Friday, March 13, 2009 Participants: Paul Webb, TRC Russ Townsend, EBCI THPO Lisa Stopp, UKB THPO Dr. Richard Allen, CNO THPO Parks Preston, FAA The following points were discussed: Paul Webb reviewed the work completed to date. An email was sent by Paul on 3/13/2009 at 12:43 PM giving an overview of the data recovery effort. The disposition of the two known graves was discussed. There has been no exploration of grave features and no future investigation will occur. The two burial sites will remain in place. 2. Procedures for future discoveries were discussed. Parks began by outlining Steve Claggett's proposal to, "Identify, replace any displaced bone, cover with soil/filter cloth (maybe to include metal/rebar to permit precise location later), and work can continue around this location. Russ stated that it sounded o.k. and asked the others for comment. No objections. A rebar grate will be placed over each burial site before backfilling or construction. Notification to the consulting parties will • take place through TRC's weekly updates. Lisa asked for detailed numbers in the weekly update. 3. The reburial schedule was discussed in conjunction with a site visit for representatives of the three Tribes. Parks stated that Macon County has agreed to cover the travel expenses and federal per diem rates would apply. Parks agreed to see if Macon County could book the flights directly. Tribal representatives will coordinate dates and respond to FAA or Macon County. FAA will coordinate with Macon County to discuss reimbursement procedures. 4. Parks stated that archaeological monitoring is required during the construction phase and suggested TRC continue in that capacity. No objection. Russ stated that he wanted to make sure adequate staff was on-site to provide proper coverage. A scope of work will be circulated for comment to all three Tribes. 5. Dr. Allen wanted to be sure that he is included in all correspondence. 6. Dr. Allen questioned the public visit planned at the site. FAA will obtain details regarding the public visits and coordinate with Tribal representatives. Details will include: Dates/hours, access, protective measures, security, etc. 0 r1 u R3-osC) t va Appendix N 0 Revised Alternatives Analysis February 2009 Macon County Airport Authority Revised October 2009 Runway Extension Project Alternatives Analysis • Alternative Analysis Macon County Airport Authority Runway Extension Project Franklin, Macon County, North Carolina Various alternatives were investigated for the proposed runway extension project at the Macon County Airport. The following includes descriptions of options considered during the design process of this project. Additionally, drawings have been included to illustrate the alternatives. Runway Extension Alternatives: Several alternatives were considered for a runway extension of 5,000 feet at the Macon County Airport. In all cases, with the exception of the "No-Build" Scenario, Runway Safety Area (RSA) improvements are included either as part of a proposed runway extension or as an upgrade of the existing RSA to conform to FAA standards. The RSA is the area beyond the runway utilized for reducing the risk of damage to airplanes in the event of an excursion from the runway. Typically, the RSA includes pockets of undeveloped land in order to maintain clear approaches to the airport. Inclusion of the RSA improvements in the scenarios is indicative of the Federal requirement to address deficient safety areas. Alternative A: Extending Runway 7 west 600 feet (preferred) is Alternative A includes extending the existing 4,400 ft. runway and taxiway by 600 feet west of Runway 7 and to construct a Runway Safety Area (RSA) to FAA standards. This alternative is preferred because there are several advantages including: • Extending runway within existing airport property boundaries with no additional land acquisition required; • Development of this area would not involve extensive clearing and grubbing of forested habitat. Existing extension area consists of grass- covered pastureland; • Available mitigation for environmental and archaeological impacts; and • Project may be completed in reasonable time frame with reasonable financial goals. This alternative includes constructing approximately 150 linear feet of new stream channel to divert upstream hydrology from lotla Branch and Wetland 1 into 560 feet of 72 inch and 124 feet of double 60 inch reinforced concrete pipe (RCP) that will tie into the existing double 60 inch RCP culvert under Airport Road and outlet into lotla Creek south of the runway. The environmental concerns associated with this alternative include unavoidable impacts to 748.86 linear feet of lotla Branch and 0.17 acre of adjacent wetlands • (Wetlands 1, 2, and 3), potential downstream impacts to threatened and or endangered species through sedimentation pollution, and disturbances to known archaeological features (Site 31MA77). -1- February 2009 Macon County Airport Authority Revised October 2009 Runway Extension Project Alternatives Analysis • Stream and wetland impacts are currently proposed to be mitigated through payment into the North Carolina Ecosystem Enhancement Program (NCEEP) In-Lieu of Fee Fund at a 2:1 ratio. The NCEEP has approved the Airport Authority's request for mitigation until February 26, 2010. During construction of the project, best management practices will be implemented in order to avoid and minimize erosion and sedimentation to surface waters of lotla Creek which could potentially impact threatened and endangered species downstream. As a result, all proposed pipes are designed to be installed at a flatter slope than the existing roadway culvert in order to reduce water velocities. Increased runoff generated from this project will be controlled using underground detention located in the infield between the runway and taxiway safety areas. Post construction measures will include periodic sweeping of the new airport pavement to reduce suspended solids prior to reaching the grass shoulders. Grass swales and filter strips will be installed in grading areas to facilitate sediment attenuation and pollutant removal prior to any stormwater discharge off airport property. Archaeological impacts are currently being addressed through an ongoing data recovery plan. The data recovery plan includes stripping and mapping of 100% of runway extension footprint. The survey work includes stripping the entire footprint of the proposed runway extension area of topsoil. Once this has been completed all features identified during the stripping will be mapped, left in place, and covered up with the removed topsoil or the runway extension fill depending on the timing. This process will preserve features and or artifacts found in the footprint and will • eliminate potential disturbances from the runway extension project. Once the project is completed, the features or artifacts identified will be encapsulated underneath the runway extension. The goal of the data recovery plan is to describe the people who were buried at this site, to characterize and explain any skeletal traits, pathologies or anomalies of the people and to provide information concerning the lifestyles and histories of the people. Although, environmental impacts are unavoidable, these impacts will be appropriately mitigated. Alternative A meets the projects goals. Completion of this alternative will increase the airport infrastructure allowing safer access to the region. Alternative B: Extending Runway 25 to the east 600 feet. (opposite end) Alternative B includes extending Runway 7/ 25 to the east 600 feet. Similar to Alternative A, Alternative B would have archaeological impacts and impacts to lotla Creek; however the most significant constraint for this alternative is the proximity to Lyle Knob Mountain Range. A portion of Lyle Knob Mountain Range falls within four nautical miles of the departure end of Runway 25. If the runway is extended in this direction, this mountainous terrain would be included in the approach surface, displacing the runway threshold, and reducing the utility and usefulness of the airport. This alternative was finally ruled out by the designers due to the significant amount of property that would need to be acquired. It has been estimated that • approximately 20 acres of residential property would need to purchase for the physical construction of the runway safety area. -2- February 2009 Revised October 2009 r? ?J Macon County Airport Authority Runway Extension Project Alternatives Analysis Alternative C: Extending both ends of the Runway by 300 feet. This alternative includes extending each end of the runway 300 feet to achieve the total 5,000 feet needed to increase access and safety. Since each end would be extended, completely new extended Runway Safety areas would be constructed as part of the project to meet FAA safety requirements. As with the other alternatives, this course of action raises concern regarding terrain, additional archaeological testing, placement of culverts, and property acquisition. Alternative D: Only extending RSA at both runway ends without lengthening of runway pavement. This would increase each extended RSA's length to 300 feet, consistent with FAA's standards for a B-II Airport Reference code. While this alternative would fulfill the Runway Safety Area improvement aspects of the Airport's purpose and need, it does not provided the additional departure and stopping distances requirements for the design aircraft at the Macon County Airport. Alternative E: No action • If no action is taken, the Macon County Airport will be unable to keep up with current FAA safety recommendations. Conclusions for Runway Extension Alternatives Based on this review, it was determined that no alternative is without impacts. Many of these alternatives raised concerns regarding significant wetland and stream impacts, mountainous terrain, additional archaeological testing, property acquisition, and not meeting additional departure and stopping distance requirements. The proposed project location (Alternative A) was selected based on the least amount of adverse impacts while meeting the overall project goals. Although the proposed runway extension location will have unavoidable impacts to lotla Branch, wetlands, and archaeology; these impacts are the least extensive and mitigation is available. • -3- w Q 0 z o wL O zQ Q ?? so (n V) or go W F- O S=1 C:) LLI X 0 bid LLJ Z p () ?aa w Q = w -9 Q Z W D a gds X O Z Q :j o Q Q V) m + . a' ?f Z Q of Z' X W Z ° O ?= Q X Z W = N F- >- W W Z w° <ZLLJ %? ° Q Q Q Z w WFW - > XZ Y" W W -1 af X Z IiJ ®?

The distances the airport owner. * lares available for the airplane's takeoff run, takeoff stance, accelerate-stop distance, and landing distance requirements. The distances are: Takeoff run available (TORA). The runway length declared available and suitable for the ground run of an airplane taking off, 'T'akeoff distance available (TODA). The TORA plus'the length of any remaining runway or clearway (CWY) beyond the far end of the TORA; NOTE: The full length of TODA may not be usable for all takeoffs because of obstacles in the departure area. The usable TODA length is aircraft performance dependent and, as such, must be determined by the aircraft operator before each takeoff and requires knowledge of the location of each controlling obstacle in the departure area, Accelerate-stop distance available (ASDA). The runway plus stopway (SWY) length declared available and suitable for the acceleration and deceleration of an airplane aborting a takeoff; and Landing distance available (LDA). The runway length declared available and suitable for a landing airplane. Fixed By Function NAYAID. An air navigation aid OVAID) that must be positioned in a particular location in order to provide an essential benefit for civil aviation is fixed by function. Exceptions are: a. Equipment shelters, junction boxes, transformers, and other appurtenances that support a fixed by function NAVAID are not fixed by function unless operational requirements require them to be located in close proximity to the NAYAID. b. Some NAVAIDs, such as localizers, can provide beneficial performance even when they are not located at their optimal location. These NAVAIDS are not fixed by function. Frangible NAYAID. A navigational aid (NAVAID) which retains its structural integrity and stiffness up to a designated maximum load, but on impact from a greater load, breaks, distorts, or yields in such a manner as to present the mininnum hazard to aircraft. The term NAVAID includes electrical and visual air navigational aids, lights, signs, and associated supporting equipment. Hazard to Air Navigation. An object which, as a result of an aeronautical study, the FAA determines will have a substantial adverse effect upon the safe and efficient use of Sri., le airspace by aircraft, operation of air navigation s, or existing or potential airport capacity. 2 9/29/06 Large Airplane. An airplane of more than 12,500 pounds (5 700 kg) maximum certificated takeoff weight. Low Impact Resistant Supports (LIRS). Supports designed to resist operational and environmental static loads and fail when subjected to a shock load such as that from a colliding aircraft. Object. Includes, but is not limited to above ground structures, NAVAIDs, people, equipment, vehicles, natural growth, terrain, and parked aircraft. Object Free Area (OFA). An area on the ground centered on a runway, taxiway, or taxilane centerline provided to enhance the safety of aircraft operations by having the area free of objects, except for objects that need to be located in the OFA for air navigation or aircraft ground maneuvering purposes. Obstacle Clearance Surface (OCS). An inclined obstacle evaluation surface associated with a glidepath. The separation between this surface and the glidepath angle at any given distance from GPI defines the MINIMUM required obstruction clearance at that point. Obstacle Free Zone (Ol7). The OFZ is the airspace below 150 feet (45 m) above the established airport elevation and along the runway and extended runway centerline that is required to be clear of all objects, except for frangible visual NAVAIDs that need to be located in the OFZ because of their function, in order to provide clearance protection for aircraft landing or taking off from the runway, and for missed approaches. The OFZ is sub-divided as follows: Runway OFZ. The airspace above a surface centered on the runway centerline. Inner-approach OFZ The airspace above a surface centered on the extended runway centerline, It applies to runways with an approach lighting system. Inner-transitional OFZ. The airspace above the surfaces located on the outer edges of the runway OFZ and the inner-approach OFZ. It applies to runways with approach visibility minimums lower than 3/4-statute mile (1200 m). Obstruction to Air Navigation. An object of greater height than any of the heights or surfaces presented in Subpart C of Code of Federal Regulation (14 CPR), Part 77. (Obstructions to air navigation are presumed to be hazards to air navigation until an FAA study has determined otherwise.) Precision Approach Category I (CAT 1) Runway. A runway with an instrument approach procedure which provides for approaches to a decision height (DH) of not less than 200 feet (60 in) and visibility of not less than 1/2 mile (800 in) or Runway Visual Range (RVR) 2400 (RVR 1800 with operative touchdown zone and runway centerline lights). Chap I AC 150/5300-13 CHG 8 d. Threshold Displacement. Incremental 0 provements that involve the displacement of a landing eshold need to be carefully planned so that they do not ncur unnecessary costs or create situations that could compromise operational safety. (1) Runway thresholds that are displaced temporarily pending the planned relocation of objects (such as Localizer antennas) should consider the extra costs associated with re-arranging the runway lights, approach lights and navigational aids. (2) The displacement of a threshold that does not also include relocation of the lead-in taxiway can create an undesirable and confusing operating environment for the pilot. (See paragraph 204.) e. Allowance for Navigational Aids. The RSA is intended to enhance the margin of safety for landing or departing aircraft. Accordingly, the design of an RSA must account for navigational aids that might impact the effectiveness of the RSA: (1) RSA grades sometimes require approach lights to be mounted on massive towers that could create a hazard for aircraft. Therefore, consider any practicable RSA construction to a less demanding grade than the standard grade to avoid the need for massive structures. (2) Instrument landing system (ILS) facilities ide slopes and localizers) are not usually required to be 40cated inside the RSA. However, they do require a graded area around the antenna. (See chapter 6 for more information on the siting of ILS facilities.) RSA construction that ends abruptly in a precipitous drop-off can result in design proposals where the facility is located inside the RSA. Therefore, consider any practicable RSA construction beyond the standard dimensions that could accommodate ILS facilities if and when they are installed. 306. OBSTACLE FREE ZONE (OM. The OFZ clearing standard precludes taxiing and parked airplanes and object penetrations, except for frangible visual NAVAIDs that need to be located in the OFZ because of their function. The runway OFZ and, when applicable, the precision OFZ, the inner-approach OFZ, and the inner- transitional OFZ comprise the obstacle free zone (OFZ). Figures 3-2, 3-3, 3-4, 3-5,and 3-6 show the OFZ. a. Runway OFZ (ROFZ). The runway OFZ is a defined volume of airspace centered above the runway centerline. The runway OFZ is the airspace above a surface whose elevation at any point is the same as the elevation of the nearest point on the runway centerline. The runway OFZ extends 200 feet (60 m) beyond each end of the runway. Its width is as follows: (1) For runways serving small airplanes lusively: 9/30/04 (a) 300 feet (90 m) for runways with lower than 3/4-statute mile (1200 m) approach visibility minimums. (b) 250 feet (75 m) for other runways serving small airplanes with approach speeds of 50 knots or more. (c) 120 feet (36 m) for other runways serving small airplanes with approach speeds of less than 50 knots. (2) For runways serving large airplanes, 400 feet (120 m). b. Inner-approach OFZ. The inner-approach OFZ is a defined volume of airspace centered on the approach area. It applies only to runways with an approach lighting system. The inner-approach OFZ begins 200 feet (60 m) from the runway threshold at the same elevation as the runway threshold and extends 200 feet (60 m) beyond the last light unit in the approach lighting system. Its width is the same as the runway OFZ and rises at a slope of 50 (horizontal) to I (vertical) from its beginning. C. Inner-transitional OFZ. The inner- transitional OFZ is a defined volume of airspace along the sides of the runway OFZ and inner-approach OFZ. It applies only to runways with lower than 3/4-statute mile (1200 m) approach visibility minimums. (1) For runways serving small airplanes exclusively, the inner-transitional OFZ slopes 3 (horizontal) to 1 (vertical) out from the edges of the runway OFZ and inner-approach OFZ to a height of 150 feet (45 m) above the established airport elevation. (2) For runways serving large airplanes, separate inner-transitional OFZ criteria apply for Category (CAT) I and CAT II/III runways. (a) For CAT I runways, the inner- transitional OFZ begins at the edges of the runway OFZ and inner-approach OFZ, then rises vertically for a height "H", and then slopes 6 (horizontal) to 1 (vertical) out to a height of 150 feet (45 in) above the established airport elevation. 1) In U.S. customary units, Hk,, = 61 - 0.094(5,,,) - 0.003(B,,). 2) In SI units, K.- = 18.4 - 0.094(S.., ) - 0.003(E„m,rs). 3) S is equal to the most demanding wingspan of the airplanes using the runway and E is equal to the runway threshold elevation above sea level. (b) For CAT 11/III runways, the inner- transitional OFZ begins at the edges of the runway OFZ and inner-approach OFZ, then rises vertically for a height "H", then slopes 5 (horizontal) to I (vertical) out to a 22 Chap 3 LJ 0 • 9/30/04 distance "Y" from runway centerline, and then slopes 6 (horizontal) to 1 (vertical) out to a height of 150 feet (45 in) above the established airport elevation. 1) In U.S. customary units, R. = 53 - 0.13(9,kn) - 0.0022(Er.) and distance Yr,,, = 440 + 1.08(SRn) - 0.024(Ekn). 2) In SI units, H,„n,„ = 16 - 0,13(S.n )- 0.0022(E,,,_) and distance Y?n? = 132 + 1.08(Smnn,) - 0.024(E,,,n,, ). 3) S is equal to the most demanding wingspan of the airplanes using the runway and E is equal to the runway threshold elevation above sea level. Beyond the distance "Y" from runway centerline the inner-transitional CAT II/III OFZ surface is identical to that for the CAT I OFZ. d. Precision OFZ. The Precision Obstacle Free Zone (POFZ) is defined as a volume'of airspace above an area beginning at the runway threshold, at the threshold elevation, and centered on the extended runway centerline, 200 feet (60m) long by 800 feet (240m) wide. See figure 3- 6. The surface is in. effect only when all of the following operational conditions are met: (1) Vertically guided approach (2) Reported ceiling below 250 feet and/or visibility less than % statute mile (or RVR below 4000 feet) (3) An aircraft on final approach within two (2) miles of the runway threshold. When the POFZ is in effect, a wing of an aircraft holding on a taxiway waiting for runway clearance may penetrate the POFZ; however neither the fuselage nor the tail may infringe on the POFZ. The POFZ is applicable at all runway ends including displaced thresholds. Note: POFZ takes effect no later than January 1, 2007 for all runway ends at which it applies. 307. OBJECT FREE AREA. The runway object free area (OFA) is centered on the runway centerline. The runway OFA clearing standard requires clearing the OFA of above ground objects protruding above the runway safety area edge elevation. Except where precluded by other clearing standards, it is acceptable to place objects that need to be located in the OFA for air navigation or aircraft ground maneuvering purposes and to taxi and hold aircraft in the OFA. Objects non-essential for air navigation or aircraft ground maneuvering purposes are not to be placed in the OFA. This includes parked airplanes Chap 3 AC 150/5300-13 CHG 8 and agricultural operations. Tables 3-1, 3-2, and 3-3 specify the standard dimensions of the runway OFA. Extension of the OFA beyond the standard length to the maximum extent feasible is encouraged. See figure 2-3. 308. CLEARWAY STANDARDS. The clearway (See figure 3-7) is a clearly defined area connected to and extending beyond the runway end available for completion of the takeoff operation of turbine-powered airplanes. A clearway increases the allowable airplane operating takeoff weight without increasing runway length. a. Dimensions. The clearway must be at least 500 feet (150 m) wide centered on the runway centerline. The practical limit for clearway length is 1,000 feet (300 m). b. Clearway Plane Slope. The clearway plane slopes upward with a slope not greater than 1.25 percent. C. Cle in . Except for threshold lights no higher than 26 inches (66 cm) and located off the runway sides, no object or terrain may protrude through the clearway plane. The area over which the clearway lies need not be suitable for stopping aircraft in the event of an aborted takeoff. d. Control. An airport owner interested in providing a clearway should be aware of the requirement that the clearway be under its control, although not necessarily by direct ownership. The purpose of such control is to ensure that no fixed or movable object penetrates the clearway plane during a takeoff operation. e. Notification. When a clearway is provided, the clearway length and the declared distances, as specified in appendix 14, paragraph 7, shall be provided in the Airport/Facility Directory (and in the Aeronautical Information Publication (AIP), for international airports) for each operational direction. 309. STOPWAY STANDARDS. A stopway is an area beyond the takeoff runway, centered on the extended runway centerline, and designated by the airport owner for use in decelerating an airplane during an aborted takeoff. It must be at least as wide as the runway and able to support an airplane during an aborted takeoff without causing structural damage to the airplane. Their limited use and high construction cost, when compared to a full-strength runway that is usable in both directions, makes their construction less cost effective. See figure 3-8. When a stopway is provided, the stopway length and the declared distances, as specified in appendix 14, paragraph 7, shall be provided in the Airport/Facility Directory (and in the Aeronautical Information Publication for international airports) for each operational direction. 23 1/3/08 AC 150/5300-13 CHG 12 Table 3-1.

When a stopway is provided, the length begins at the stopway end. 4/ The standard RSA length beyond the runway end may be reduced to the standard RSA length prior to landing threshold if a standard Engineered Materials Arresting System (EMAS) is provided. To qualify for this reduction, the EMAS installation must provide the ability to stop the critical aircraft exiting the end of the runway at 70 knots, and the runway must provide either instrument or visual vertical guidance for approaches in the opposite direction. See AC 150/5220-22. 0 51 The runway object free area length beyond the end of the runway never exceeds the standard RSA length beyond the runway end as provided by note 4 above. Chap 3 25 8/28/2007 AC 150/5200-33B SECTION 1. GENERAL SEPARATION CRITERIA FOR HAZARDOUS WILDLIFE ATTRACTANTS ON OR NEAR AIRPORTS. 1-1. INTRODUCTION. When considering proposed land uses, airport operators, local planners, and developers must take into account whether the proposed land uses, including new development projects, will increase wildlife hazards. Land-use practices that attract or sustain hazardous wildlife populations on or near airports can significantly increase the potential for wildlife strikes. The FAA recommends the minimum separation criteria outlined below for land-use practices that attract hazardous wildlife to the vicinity of airports. Please note that FAA criteria include land uses that cause movement of hazardous wildlife onto, into, or across the airport's approach or departure airspace or air operations area (AOA). (See the discussion of the synergistic effects of surrounding land uses in Section 2-8 of this AC.) The basis for the separation criteria contained in this section can be found in existing FAA regulations. The separation distances are based on (1) flight patterns of piston- powered aircraft and turbine-powered aircraft, (2) the altitude at which most strikes happen (78 percent occur under 1,000 feet and 90 percent occur under 3,000 feet above ground level), and (3) National Transportation Safety Board (NTSB) • recommendations. 1-2. AIRPORTS SERVING PISTON-POWERED AIRCRAFT. Airports that do not sell Jet-A fuel normally serve piston-powered aircraft. Notwithstanding more stringent requirements for specific land uses, the FAA recommends a separation distance of 5,000 feet at these airports for any of the hazardous wildlife attractants mentioned in Section 2 or for new airport development projects meant to accommodate aircraft movement. This distance is to be maintained between an airport's AOA and the hazardous wildlife attractant. Figure 1 depicts this separation distance measured from the nearest aircraft operations areas. 1-3. AIRPORTS SERVING TURBINE-POWERED AIRCRAFT. Airports selling Jet-A fuel normally serve turbine-powered aircraft. Notwithstanding more stringent requirements for specific land uses, the FAA recommends a separation distance of 10,000 feet at these airports for any of the hazardous wildlife attractants mentioned in Section 2 or for new airport development projects meant to accommodate aircraft movement. This distance is to be maintained between an airport's AOA and the hazardous wildlife attractant. Figure 1 depicts this separation distance from the nearest aircraft movement areas. 1-4. PROTECTION OF APPROACH, DEPARTURE, AND CIRCLING AIRSPACE. For all airports, the FAA recommends a distance of 5 statute miles between the farthest edge of the airport's AOA and the hazardous wildlife attractant if the attractant could • cause hazardous wildlife movement into or across the approach or departure airspace. 1 8/28/2007 AC 150/5200-33B .7 • • Figure 1. Separation distances within which hazardous wildlife attractants should be avoided, eliminated, or mitigated. W W W W W W W W W W W W W W W W W W W W W W W W W W W ?? W W W ? W W ??
