'T'here shall be no excavation from or waste disposal into, jurisdictional wetlands or waters associated .with this permit without appropriate modification. Should waste or borrow sites be located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road construction activities. 3. Sediment and erosion control measures shall not be placed in wetlands or waters wiles otherwise approved by this Certification. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored upon completion of the project. 4. Placement of culverts and other structures in waters, streams and wetlands, shall be placed below the elevation of the streambed by one foot for all culverts with a diameter greater than 48-inches, and 20 percent of the culvert diameter for culverts having a diameter less than 48-inches, to allow low flow passage of water and aquatic life. Design and placement of culverts and other structures including temporary erosion control measures shall not be conducted in a manner that may result in dis-equilibrium of wetlands, streambeds or banks, adjacent to, or upstream and down stream of the above structures. 'T'he applicant is required tt~ provide evidence -that equilibrium is being maintained, if requested in writing by DWQ. If this condition is unable to be met due to bedrock or other limiting features encountered during construction, please contact the NC DWQ for guidance on haw to proceed and to determine whether or not a permit modification wit] be required. 5. Adequate sedimentation and erosion control measures must be installed and maintained on the project site to minimize sediment transport to downstream. aquatic resources. Temporary cover (wheat, millet or similar annual grain) or permanent herbaceous cover should be planted on all bare soil within fifteen (15) days of ground disturbing activities to provide long-term erosion. control. Erosion control mating should be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas. Matting should be secured in place with staples or wherever possible, live stakes of native trees. Straw mulch and tall fescue should not be used in riparian areas. 6. "L'he culverts at Station Nos. 7-f~55, 28-+-50, 49+20, 50-~ 50, 61+40, 67+80, 73+60, 78+20, 85+45, 97 x-80, 99+-40, 105+35, 253+68 and 256-+-73, will remain perched after construction. 7.

The dimension, pattern and profile of the stream, above and below the crossing, should not be modified. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 9. All storznwater runoff shall be directed as sheet flow through stream buffers at nonerosive velocities, unless otherwise approved by this certircation. 10. Native riparian vegetation (e.g. rhododendron, clog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. 11. "1'he use of riprap above the Normal I-Iigh Water Mark shall be minimized. Any riprap placed for stream stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage. 12. Ilcavy equipment should be operated from the banks rather than in the stream channels in order to minimize sedimentation and reduce the introduction of other pollutants into the stream. 13. All mechanized equipment operated near surface waters must be regularly inspected daily and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 14. Rock check dams at culvert outlets should be removed at project completion to avoid impeding aquatic life movement. 15. All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP measures from the most current version of NCDOT Construction and Maintenance Activities manual such as sandbags, rock berms, cofferdams and other diversion structures should be used to prevent excavation in flowing water. l G.

EASLEY GOVERNOR August 23, 2006 Mr. David Baker, NCDOT Regulatory Project Manager U.S. Army Corps of Engineers 151 Patton Avenue, Room 208 Asheville, NC 28801-2714 LYNDO TIPPETT S ECREi'ARY 6(~n~so Subject: Corrected Nationwide 13 and Nationwide 14 Permit Application SR 1136, Skyuka Mountain Road Polk County State Project # 140.075026 (DWQ Minor Permit Fee $200.00) Dear Mr. Baker: The North Carolina Department of Transportation (NCDOT) is proposing to widen, grade, drain and pave SR 1136, Skyuka Mountain Road, in Polk County. This proposal entails widening and paving the existing gavel road to a standard 18-foot roadway. The work is necessary to improve safety and reduce maintenance costs. Funds have been allocated for this project and NCDOT would like to perform this work during the 2006-07 and 2007-08 paving seasons. Work the first year would be from Sta. 0+00 to 118+00 and the second year from Sta. 118+00 to 263+00. Skyuka Mountain Road is a secondary gavel road, which conveys only local traffic. I am enclosing a PCN, astraight-line diagam with the proposed erosion control and construction limits along this project. In addition, I am sending a typical section of the road, drawings for the pipe culvert replacements, a marked county map and USGS quad map. The North Carolina Natural Heritage Database was checked for records of threatened and endangered species. There are no records of aquatic threatened or endangered species for the unnamed tributaries of Skyuka Creek and Horse Creek. There are no records of threatened or endangered aquatic species for these watersheds. The unnamed tributaries to Skyuka Creek and Horse Creek are small (1-3 feet wide) and do not have sufficient flow to support mussels and are not likely to support fish within the project area. Therefore, the project will have no effect on threatened or endangered aquatic species. During preliminary investigations for this project, records for the federally endangered white irisette (Sysri~zchium dichotoniunt) were found in the North Carolina Natural Heritage Database. Subsequently, NCDOT staff made a general reconnaissance of Skyuka Mountain Road in the proximity of the known records and identified several plants. Further reconnaissance revealed white irisette plants from numerous locations along the road. Systematic surveys in 2004 and 20051ocated 846 plants on the road or in close proximity to the road. Due to the potential for unavoidable impacts to the white irisette, NCDOT entered into formal Section 7 consultation with the U.S. Fish and Wildlife Service. A Biological Assessment (BA) has been prepared and we believe a Biological Opinion will result in a determination of "May Effect-May Adversely Effect" for the white irisette. Due to the unavoidable impacts to the white irisette, a number of measures have been implemented for this project. The project will be constructed in two parts over atwo-year period to minimize the spread of invasive species and to reduce the potential for aberrant construction impacts that may be greater with multiple contractors working on the project. Preliminary invasive species control has been implemented and a formal plan written. Special erosion control measures and seeding mixtures are proposed. These measures and compensatory mitigation for the unavoidable impacts are detailed in the BA that will be subrnitted separately. Impacts to historic or cultural resources are not anticipated. If the State Historic Preservation Office (SHPO) and the Office of State Archaeology determines that further investigations are required, NCDOT will conduct the appropriate site investigations and obtain compliance from SHPO prior to project construction. The best management practices will be used to minimize and control sedimentation and erosion on this project. The construction foreman will review all sedimentation control measures during installation to ensure sedimentation is being effectively controlled. If the planned devices are not functioning as intended, they will be replaced immediately with better devices. The sedimentation control devices will be in place prior to pipe culvert removal and will remain in place until the new pipe is in place. Impacts to Waters of the United States The unnamed tributaries to Skyuka Creek and Horse Creek are small and only one of the tributaries to Skyuka Creek is shown on the USGS topographic map. However, all of the streams appear to have perennial flow except for one. The channels are well defined and composed of bedrock, cobble, sand and gravel. These channels lack vegetation. The U.S. Army Corps of Engineers determined the streams are jurisdictional. In order to replace these culverts, it will be necessary to impact waters of the United States in the Broad River Basin. Specifically, NCDOT is requesting to replace 19 culverts in unnamed tributaries to Skyuka Creek (DWQ Class B and DWQ Class C) and two culverts in unnamed tributaries of Horse Creek (DWQ Class WS-III). NCDOT is also requesting authorization to install bank stabilization devices as shown on the accompanying erosion control plans from Sta. 164+65 to 165+75 along an unnamed tributary of Skyuka Creek.

EASLEY LYNDO TIPPETT GOVERNOR SECRETARY April 20, 2006 r~ ARE '~~` ~-~ Ms. Angie Pennock, NCDOT Regulatory Project Manager ~ ~.~ ~, U.S. Army Corps of Engineers 151 Patton Avenue, Room 208 ~ ~-~ Asheville, NC 28801-2714 Subject: Nationwide 13 and Nationwide 14 Permit Application SR 1136, Skyuka Mountain Road Polk County ~'~ State Project # 140.075026 (DWQ Minor Permit Fee $?66:60) ~7.~ Dear Ms. Pennock: The North Carolina Department of Transportation (NCDOT) is proposing to widen, grade, drain and pave SR 1136, Skyuka Mountain Road, in Polk County. This proposal entails widening and paving the existing gravel road to a standard 18-foot roadway. The work is necessary to improve safety and reduce maintenance costs. Funds have been allocated for this project and NCDOT would like to perform this work during the 2006-07 and 2007-08 paving seasons. Work the first year would be from Sta. 0+00 to l 18+00 and the second year from Sta. 118+00 to 263+00. Skyuka Mountain Road is a secondary gravel road, which conveys only local traffic. I am enclosing a PCN, astraight-line diagram with the proposed erosion control and construction limits along this project. In addition, I am sending a typical section of the road, drawings for the pipe culvert replacements, a marked county map and USGS quad map. The North Carolina Natural Heritage Database vas checked for records of threatened and endangered species. There are no records of aquatic threatened or endangered species for the unnamed tributaries of Skyuka Creek, Horse Creek and White Oak Creek. There are no records of threatened or endangered aquatic species for these watersheds. The unnamed tributaries to Skyuka Creek, Horse Creek and White Oak Creek are small (1-3 feet wide) and do not have sufficient flow to support mussels and are not likely to support fish within the project area. Therefore, the project will have no effect on threatened or endangered aquatic species. During preliminary investigations for this project, records for the federally endangered white irisette (Sysrinchium dichotomum) were found in the North Carolina Natural Heritage Database. Subsequently, NCDOT staff made a general reconnaissance of Skyuka Mountain Road in the proximity of the known records and identified several plants. Further reconnaissance revealed white irisette plants from numerous locations along the road. Systematic surveys in 2004 and 20051ocated 846 plants on the road or in close proximity to the road. Due to the potential for unavoidable impacts to the white irisette, NCDOT entered into formal section 7 consultation with the U.S. Fish and Wildlife Service. A Biological Assessment (BA) has been prepared and we believe a Biological Opinion will result in a determination of "May Effect-May Adversely Effect" for the white irisette. Due to the unavoidable impacts to the white irisette, a number of measures have been implemented for this project. The project will be constructed in two parts over atwo-year period to minimize the spread of invasive species and to reduce the potential for aberrant construction impacts that may be greater with multiple contractors working on the project. Preliminary invasive species control has been implemented and a formal plan written. Special erosion control measures and seeding mixtures are proposed. These measures and compensatory mitigation for the unavoidable impacts are detailed in the BA that will be submitted separately. Impacts to historic or cultural resources are not anticipated. If the State Historic Preservation Office (SHPO) and the Office of State Archaeology determines that further investigations are required, NCDOT will conduct the appropriate site investigations and obtain compliance from SHPO prior to project construction. The best management practices will be used to minimize and control sedimentation and erosion on this project. The construction foreman will review all sedimentation control measures during installation to ensure sedimentation is being effectively controlled. If the planned devices are not functioning as intended, they will be replaced immediately with better devices. The sedimentation control devices will be in place prior to pipe culvert removal and will remain in place until the new pipe is in place. Impacts to Waters of the United States The unnamed tributaries to Whiteoak Creek, Skyuka Creek and Horse Creek are not shown on USGS topol,~raphic maps. However, all of the streams appear to have perennial flow except for one. The channels are well defined and composed of bedrock, cobble, sand and gravel. These channels lack vegetation. The U.S. Army Corps of Engineers determined the streams are jurisdictional. In order to replace these culverts, it will be necessary to impact waters of the United States in the Broad River Basin. Specifically, NCDOT is requesting to replace 21 culverts in unnamed tributaries to Whiteoak Creek (DWQ Class C), Skyuka Creek (DWQ Class B and DWQ Class C) and Horse Creek (DWQ Class WS-III). NCDOT is also requesting authorization to install bank stabilization devices as shown on the accompanying erosion control plans from Sta. 164+65 to 165+75.

Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. Water will be diverted durine the installation of the nines to minimize sedimentation. The pipes will be placed below the stream bottom to minimize fra~tnentation of aquatic habitat. Headwalls will be used on most of the pipes and the standard widths have been reduced in some areas to minimize the footprint of the road. _ Page 6 of 9 1\~Iitibation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide.html. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP).

These areas will require stage seeding and mulching. • Begin grading of roadway ditches. Place erosion control measures along roadway ditches as grading progresses and conditions allow. • Seed and mulch all disturbed areas as soon as any phase of grading is completed. (Note there are 15 working.days/30 calendar days to complete seeding and mulching. A working day is defined as a day exclusive of Saturday or Sunday during which weather conditions or soil conditions permit land-disturbing activity.) • Clean out and/or rework all temporary erosion control measures after any significant rainfall event (or as otherwise needed). These measures should be maintained until a permanent vegetative.cover is established. Wet Pipe Installation Schedule • Install erosion control devices. • Remove material and existing pipe while limiting, as much as possible, material and sediment from entering the stream and/or escaping from the project. • Prepare pipe foundation while taking care to limit material and sediment from entering the stream and/or escaping from the project. Where possible new grade should be below the existing streambed. If needed, bedding material will be clean stone (especially in Trout and HQW waters). • Place new pipe and compact fill. • Install slope protection on outlet and inlet ends of pipe. Also complete installation of erosion control measures and perform maintenance as needed on existing measures. • Establish permanent vegetation as soon as possible.

B. Setzer, P.E. Division Engineer N C Department of Transportation 253 Webster Road Sylva, North Carolina 28779 Dear Mr. Setzer: You have our approval, in accordance with the attached conditions and those listed below, to impact 68 linear feet in nine (9) unnamed tributaries to Whiteoak Creek, 48 linear feet in nine (9) unnamed tributaries to Horse Creek, installation of 110 linear feet of gabion baskets along an unnamed tributary to Horse Creek for streambank stabilization and 30 linear feet in three (3) unnamed tributaries of Skyuka Creek (146 linear feet of new pipe, 110 linear feet of gabion baskets and temporary dewatering), in order to make improvements to NCSR 1136 (Skyuka Mountain Road) in Polk County. The project should be constructed in accordance with your application dated April 20, 2006 (received May 4, 2006), including the environmental commitments made in the application letter. After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Nos. 3495, 3404 and 3366, corresponding to the U.S. Army Corps of Engineers Nationwide Permit Numbers 13, 14 and 33. In addition, you must acquire any other federal, state or local permits before you proceed with your project including (but not limited to) Sediment and Erosion Control, Nori- Discharge and Water Supply Watershed regulations. This Water Quality Certification will expire with the accompanying 404 Permit issued by the US Army Corps of Engineers. This approval is valid solely for the purpose and design described in your application (unless modified below). Should your project change, you must notify the DWQ in writing and submit a new application. If the property is sold, the new owner must be given a copy of this Certification and approval letter, and is thereby responsible for complying with all the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or if total impacts to streams (now or in the future) exceed 150 linear feet, compensatory mitigation may be required as described in i5A NCAC 2H .0506 (h) (6) and (7). For this approval to be valid, yoze must follow the conditions listed in the attached certification and any additional conditions listed below. 1. Erosion and sediment control practices must he in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices in order to protect surface waters standards: a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the reyuirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the project.

Setzer, P.E. June 12, 2006 Page Two c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sz~rface Mining Manual. d. The reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. 2. There shall be no excavation from or waste disposal into, jurisdictional wetlands or waters associated with this permit without appropriate modification. Should waste or borrow sites be located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road construction activities. 3. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this Certification. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored upon completion of the project. 4. Placement of culverts and other structures in waters, streams and wetlands, shall be placed below the elevation of the streambed by one foot for all culverts with a diameter greater than 48-inches, and 20 percent of the culvert diameter for culverts having a diameter less than 48-inches, to allow low flow passage of water and aquatic life. Design and placement of culverts and other structures including temporary erosion control measures shall not be conducted in a manner that may result in dis-equilibrium of wetlands, streambeds or banks, adjacent to, or upstream and down stream of the above structures. The applicant is required to provide evidence that equilibrium is being maintained, if requested in writing by DWQ. If this condition is unable to be met due to bedrock or other limiting features encountered during construction, please contact the NC DWQ for guidance on how to proceed and to determine whether or not a permit modification will be required. 5. Adequate sedimentation and erosion control measures must be installed and maintained on the project site to minimize sediment transport to downstream aquatic resources. Temporary cover (wheat, millet or similar annual grain) or permanent herbaceous cover should be planted on all bare soil within fifteen (15) days of ground disturbing activities to provide long-term erosion control. Erosion control mating should be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas. Matting should be secured in place with staples or wherever possible, live stakes of native trees. Straw mulch and tall fescue should not be used in riparian areas. 6. The culverts at Station Nos. 7+55, 28+50, 49+20, 50+50, 61+40, 67+g0, 73+60, 78+20, 85+45, 97+g0, 99+40, 105+35, 253+68 and 256+73, will remain perched after construction. 7. There shall be no impacts to the wetland between Station Nos. 82+00 and 83+50. High visibility fencing is to be installed around the wetland to protect it during construction. 8. The dimension, pattern and profile of the stream, above and below the crossing, should not be modified. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 9. All stormwater runoff shall be directed as sheet flow through stream buffers at nonerosive velocities, unless otherwise approved by this certification. 10. Native riparian vegetation (e.g. rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. 11. The use of riprap above the Normal High Water Mark shall be minimized. Any riprap placed for stream stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage. 12. Heavy equipment should be operated from the banks rather than in the stream channels in order to minimize sedimentation and reduce the introduction of other pollutants into the stream. 13. All mechanized equipment operated near surface waters must be regularly inspected daily and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 14. Rock check dams at culvert outlets should be removed at project completion to avoid impeding aquatic life movement. 15. All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP measures from the most current version of NCDOT Construction and Maintenance Activities manual such as sandbags, rock berms, cofferdams and other diversion structures should be used to prevent excavation in flowing water. 16. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. ~ Mr. J. B. Setzer, P.E. June 12, 2006 Page Three 17. If concrete is used during construction (e.g., headwalls), a dry work area should be maintained to prevent direct contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and fish kills. 18. No rock, sand or other materials shall be dredged from the stream channel, except where authorized by this certification. 19. The permittee and its authorized agents shall conduct its activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with §303(d) of the Clean Water Act) and any other appropriate requirements of State or Federal law. If DWQ determines that such standards or laws are not being met (including failure to sustain a designated achieved use) or that State of Federal law if being violated, or that further conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification. 20. This certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone except for permitted areas associated with the culvert installation. 21. During the construction of the project, no staging of equipment of any kind is permitted in waters of the U.S., or protected riparian buffers. 22. Upon completion of the project, the NCDOT Division Engineer, shall complete and return the enclosed "Certificate of Completion Form" to notify NCDWQ when all work included in the §401 Certification has been completed. This form shall be returned to the Transportation Permitting Unit of the NC Division of Water Quality, 2321 Crabtree Blvd., Suite 250, Raleigh, North Carolina 27604.
