Ross Jr., Secretary North Carolina Department of Environment and Natural Resources September 14, 2006 Marisue Hilliard, Forest Supervisor National Forests in North Carolina Post Office Box 2750 Asheville, NC 28802-2750 Subject Property: King Meadows (Snowbird) Trail Bridge Approval of 401 Water Quality Certification with Additional Conditions - REVISED Dear Mr. Hilliard: Alan W. Klimek, P.E. Director Division of Water Quality DWQ Project # 06-1173 Graham County You have our approval, in accordance with the attached conditions and those listed below, to place fill within or otherwise impact approximately 60 linear feet of streams (40 linear feet permanent impact, 20 linear feet temporary impact) for the purpose of stream stabilization and access repair / replacement at the subject property, as described within your application received by the N.C. Division of Water Quality (DWQ) on July 20, 2006. After reviewing your application, we have decided these impacts are covered by General Water Quality Certification Number(s) 3494 (GC3494). The Certification(s) allows you to use Nationwide Permit(s) 3 when issued by the US Army Corps of Engineers (USACE). This Certification replaces the Certification issued to you on August 25, 2006. In addition, you should obtain or otherwise comply with any other required federal, state or local permits before you go ahead with your project including (but not limited to) Erosion and Sediment Control, Non-discharge, and stormwater regulations. Also, this approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA Permit. This approval is for the purpose that you described in your application. If you change your project beyond this approval, you must notify us and you may be required to send us 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 conditions. If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). This approval requires you to follow the conditions listed in the attached certification and any additional conditions listed below. The Additional Conditions of the Certification are: 1. Impacts Approved The following impacts are hereby approved as- long as all of the other specific and general conditions of this Certification (or Isolated Wetland Permit) are met. No other impacts are approved including incidental impacts: Amount Approved (Units) I Plan Location Stream Approximately 60 [(linear feet) 40 linear feet permanent impact, 20 linear feet temporary impact) Snowbird Creek 2. Erosion & Sediment Control Practices Erosion and sediment control practices must be 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: 401 Wetlands Certification Unit 1650 Mail Service Center, Raleigh, North Carolina 27699.1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786 / FAX 919-733.6893 / Internet http://h2o.enr.state.nc,uslncwetlands A& L ?V p.i An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper Snowbird Trail Bridge Page 2 of 6 September 14, 2006 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 requirements 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. 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 Surface Mining Manual. d. The reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. 3. No Waste, Spoil, Solids, or Fill of Any Kind No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the Pre-Construction Notification. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur. 4. No Sediment & Erosion Control Measures w/n Wetlands or Waters Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources has released the project. 5. Certificate of Completion Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer Rules, and any subsequent modifications, the applicant is required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650. 6. Construction in this creek and disturbance within a 25-foot trout buffer should be avoided during the October 15 to April 15 trout spawning period to avoid adverse effects of sediment on eggs and larvae. Sediment and erosion control measures must be implemented prior to construction and maintained on the sites to minimize sediment in downstream areas. Seeding for a temporary cover of wheat, millet, or similar annual grain or permanent herbaceous cover should occur on all bare soil within five (5) days of ground disturbing activities to provide long-term erosion control. The projects should be accomplished in stages instead of leaving large tracts exposed to further storm events. Erosion control matting 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, stakes, or, wherever possible, live stakes of native trees. Straw mulch and tall fescue should not be used in riparian areas. In addition, because of an anticipated difficulty in establishing ground cover during the winter, reseeding should be conducted, as necessary, in the spring-time with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet or other grain. 8. Only clean, large, angular rock, large woody material, or other natural stream design materials and techniques should be used for bank stabilization. Rock should not be placed in the stream channel in a manner that constricts stream flow or that will impede aquatic life movements during low flow conditions. Filter cloth should be placed behind large rock that is used for bank stabilization. Properly designed rock vanes should be constructed wherever appropriate on bank stabilization and channel realignment stream reaches to improve Snowbird Trail Bridge Page 3 of 6 September 14, 2006 channel stability and to improve aquatic habitat. Root wads should be installed low enough in the bank so that a significant portion (at least one-third) the root wad is inundated during normal flows. Should large, angular rock, large woody material, or other natural stream design materials and techniques not be sufficient for long term stability of the stream and adjacent roadway, and concrete be incorporated into the design, measures which would prevent surface waters from coming into contact with live concrete. The channel should be restored to a more stable condition. However, under no circumstances should river rock, sand or other materials be dredged from the stream channel under authorization of this permit except, if necessary, in the immediate vicinity of the eroding banks for the explicit purpose of anchoring stabilizing or flow/grade control structures or for reestablishing the natural and more stable stream channel dimensions. Stream bed materials are unstable in flowing-water situations and are unsuitable for bank stabilization. In stream dredging has catastrophic effects on aquatic life and disturbance of the natural form of the stream channel can cause downstream erosion problems. The natural dimension, pattern, and profile of the stream upstream and downstream of the permitted area should not be modified by widening the stream channel or changing its depth. No backfilling of stream bed materials is allowed under this authorization. 10. Stabilization measures should only be applied on or near existing erosion sites, leaving other stable stream bank areas in a natural condition. Grading and backfilling should be minimized and tree and shrub growth should be retained where possible to ensure long term availability of stream bank cover for aquatic life and wildlife. Backfill materials should be obtained from upland sites except in cases where excess stream bed materials are available. Berms should not be permitted because they block the floodplain, constrict and accelerate flood flows, and often fail and sometimes impede drainage during large flood events. 11. Repairs to eroded banks should be conducted in a dry work area. Sandbags or other clean diversion structures should be used to minimize excavation in flowing water. Channel realignments should be constructed by excavating the new channel from downstream to upstream before connecting it to the old channel. 12. Heavy equipment should be operated from the bank whenever possible. All mechanized equipment operated near surface waters should be inspected and maintained regularly to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids or other toxic materials. Equipment used in stream channel must be clean, new or low hour equipment. Exposure of equipment to surface waters must be minimized to the maximum extent possible. 13. Disturbed stream banks and a 25-foot vegetated zone (as required under the Trout Buffer regulations) must be restored along the construction sites to natural riparian conditions with native trees and shrubs (e.g., silky dogwood, rhododendron, dog hobble, red maple, silky willow, tag alder, black willow, sycamore) to provide long-term bank stability and stream shading. Note, silky dogwood, silky willow and black willow can be planted as live stakes collected during the dormant growing season. Cuttings should be randomly planted on four (4) foot centers from the waters edge to the top of the bank. Trees should be planted on ten (10) to twelve (12) foot centers. Stream banks,in these areas should also be seeded with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet or other grain. Replanting of vegetation within disturbed areas located within 30 feet of the streambank associated with any land disturbing activity, repair, replacement and/or maintenance must be done in a manner consistant with the Guidelines for Riparian Buffer Restoration immediately following construction. (Please see attached.) 14. If pasture along the stream is to be used for grazing, a fence must be constructed outside of the riparian zone and the stream to prevent livestock from entering these areas. 15. Diffuse Flow All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at non-erosive velocities through the protected riparian zones such that it will not re-concentrate before discharging into a Snowbird Trail Bridge Page 4 of 6 September 14, 2006 stream. If this is not possible, it may be necessary to provide stormwater facilities that are considered to remove nitrogen. This may require additional approval from this Office. 16. Turbidity Standard The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 2B..0200. Appropriate sediment and erosion control practices must be used to meet this standard. 17. No Sediment and Erosion Control Measures in Wetlands Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources or locally delegated program has released the project. Violations of any condition herein set forth may result in revocation of this Certification and may result in criminal and/or civil penalties. The authorization to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application and as authorized by this Certification, shall expire upon expiration of the 404 or CAMA Permit. If you do not accept any of the conditions of this Certification (associated with the approved wetland or stream impacts), you may ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing. This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act.

Page 2 of 10 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: This bridge site is located on Snowbird Creek. During the storms of 9/2004, high water completely destroyed this bridge and only a partial log is still visible as remains. This structure is used by hikers through the year (winter and summer) and fisherman/hunters. The stream banks have under brush of laurel and rhododendron and the over story is a hardwood-conifer canopy. 10. Overall project description in detail including the type of equipment to be used: The planned new bridge is a steel truss design with railings and a wood deck. The length is 80 feet with concrete abutments at each end. Although the new bridge will occupy the same site as the old bridge, it will be about 5 feet above the high water of 2004. Excavation for the new bridge will consist of removing material for the abutments and re- sloping the existing banks for about 20 feet on both sides of the stream to accept the riprap bank and abutment protection. A temporary in-stream support will be needed during construction when placing the two halves of the steel truss. This temporary shoring will likely be similar to an oversized sawhorse with adjustable legs to fit the stream bottom. Because of the height and length of the structure, a work pad is planned for the crane to occupy while sitting the span and placing the riprap. The existing trail on both sides of the stream is on an old road bed. Erosion and sedimentation control will be maintained throughout this project primarily through proper water management, construction sequencing, proper staging and stockpiling material, and the maintenance at all times, of suitable channel capacity for expected flow events. No equipment, fuels, lubricants, or other potential sources of water pollution will be stored in areas that could be flooded during this project. Work within the wetted perimeter of the stream will not be allowed from October 15th - April 15th. 11. Purpose of the proposed work: The King Meadows (Snowbird) Bridge will provide access for the myriad of public visitor traffic to this area. The trail is used by recreationists of all types. Placement of the designed riprap will prevent erosion of the abutments and bank erosion. The new bridge will afford a larger stream cross sectional area for future high water. IV.

Future Project Plans Are any future permit requests anticipated for this project? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. N/A VI. Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, must be listed, and must be labeled and clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) should be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet 1. Provide a written description of the proposed impacts: Placement of Riprap and crane access. The South Abutment Riprap placement is 20 feet in length; The crane access for setting the structure plans for an additional 20 ft. pad as shown. The North Abutment riprap is 20 feet in length.

Plan drawings, or other maps may be included at the applicant's discretion, so long as the property is clearly defined. For administrative and distribution purposes, the USACE requires information to be submitted on sheets no larger than 11 by 17-inch format; however, DWQ may accept paperwork of any size. DWQ prefers full-size construction drawings rather than a sequential sheet version of the full-size plans. If full-size plans are reduced to a small scale such that the final version is illegible, the applicant will be informed that the project has been placed on hold until decipherable maps are provided. 1. Name of project: King Meadows (Snowbird) Trail Bridge Construction. 2. T.I.P. Project Number or State Project Number (NCDOT Only): N/A 3. Property Identification Number (Tax PIN): N/A 4. Location County: Graham Nearest Town: Robbinsville, NC Subdivision name (include phase/lot number): N/A Directions to site (include road numbers/names, landmarks, etc.): From Robbinsville, NC, travel northerly on route 143 past the Cheoah Ranger Station for about 2.5 miles. Turn right and proceed for about 2 miles, then left onto SRI 115. Travel 2.1 miles and make a sharp left turn onto SRI 127. After 1 mile on this route, cross the concrete bridge, and immediately turn right onto SRI 120. Travel about 2 miles to the end of the asphalt, and continue on for 3.9 miles to the trailhead at the end of the road. Site coordinates (For linear projects, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) Decimal Degrees (6 digits minimum): 35.2667 ON 83.9284 °W 6. Property size (acres): The Cheoah Ranger District is 120,500 Acres. 7. Name of nearest receiving body of water: Santeetlah Lake, then the Little Tennessee River (Fontana Lake). 8. River Basin: Little Tennessee (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://li2o.enr.statc.nc.us/admin/maps/.) Page 2 of 10 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: This bridge site is located on Snowbird Creek. During the storms of 9/2004, high water completely destroyed this bridge and only a partial log is still visible as remains. This structure is used by hikers through the year (winter and summer) and fisherman/hunters. The stream banks have under brush of laurel and rhododendron and the over story is a hardwood-conifer canopy. 10. Overall project description in detail including the type of equipment to be used: The planned new bridge is a steel truss design with railings and a wood deck. The length is 80 feet with concrete abutments at each end. Although the new bridge will occupy the same site as the old bridge, it will be about 5 feet above the high water of 2004. Excavation for the new bridge will consist of removing material for the abutments and re- sloping the existing banks for about 20 feet on both sides of the stream to accept the riprap bank and abutment protection. A temporary in-stream support will be needed during construction when placing the two halves of the steel truss. This temporary shoring will likely be similar to an oversized sawhorse with adjustable legs to fit the stream bottom. Because of the height and length of the structure, a work pad is planned for the crane to occupy while sitting the span and placing the riprap. The existing trail on both sides of the stream is on an old road bed. Erosion and sedimentation control will be maintained throughout this project primarily through proper water management, construction sequencing, proper staging and stockpiling material, and the maintenance at all times, of suitable channel capacity for expected flow events. No equipment, fuels, lubricants, or other potential sources of water pollution will be stored in areas that could be flooded during this project. Work within the wetted perimeter of the stream will not be allowed from October 15th -April 15th. 11. Purpose of the proposed work: The King Meadows (Snowbird) Bridge will provide access for the myriad of public visitor traffic to this area. The trail is used by recreationists of all types. Placement of the designed riprap will prevent erosion of the abutments and bank erosion. The new bridge will afford a larger stream cross sectional area for future high water. IV.

Mitigation 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 January 15, 2002, 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 Page 6 of 10 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.
