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 incur the following impacts in order to make improvements to NCSR 1135 (Shook Cove Road) in Jackson County: • 82 linear feet of new piping impacts in six (6) unnamed tributaries to the Tuckaseegee River (Bear Lake); and • 120 linear feet of stream relocation between Station 22+62 and Station 23+82; and 0.065 acres of wetland fill between Station 8+55 and Station 9+70. The project should be constructed in accordance with your application dated April 28, 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. 3404 and 3366, corresponding to the U.S. Army Corps of Engineers Nationwide Permit Numbers 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, Non- 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 15A NCAC 2H .0506 (h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the attached certification and any additional conditions listed below. 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: 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. Setzer, P.E. June 2, 2006 Page Two 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. 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 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. 7. All channel relocations will be constructed in a dry work area and stabilized before stream flows are diverted. Channel relocations will be completed and stabilized, and must be approved on site by DWQ staff, prior to diverting water into the new channel. Whenever possible, channel relocations shall be allowed to stabilize for an entire growing season. Vegetation used for bank stabilization shall be limited to native woody species, and should include establishment of a 30-foot wide wooded and an adjacent 20-foot wide vegetated buffer on both sides of the relocated channel to the maximum extent practicable. A transitional phase incorporating coin fiber and seedling establishment is allowable. Also, riprap may be allowed if it is necessary to maintain the physical integrity of the stream, but the applicant must provide written justification and any calculations used to determine the extent of riprap coverage area. 8. Compensatory mitigation for impacts to 202 linear feet of streams at a replacement ratio of 1:1 is required. Compensatory mitigation for impacts to jurisdictional streams shall be provided by onsite stream relocation of 120 linear feet. We understand, based on the 401 Certification application, that you have chosen to perform compensatory mitigation for the remaining 82 linear feet through the North Carolina Ecosystem Enhancement Program (EEP). 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. Any riprap placed for bank stabilization should be limited to the streambank below the high water mark, and vegetation should be used for stabilization above the high water elevation. Riprap should not be place in the active thalweg channel or placed in the streambed in such a manner that precludes aquatic life passage. Bioengineering boulders or structures should be properly designed, sized and installed. '4r. J. B. Setzer, P.E. June 2, 2006 Page Three 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. 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 p1I 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 bank stabilization work. 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. If you do not accept any of the conditions of this certification, 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.

EASLEY GOVERNOR April 28, 2006 LYNDO TIPPETT SECRETARY Mr. Steve Lund, NCDOT Regulatory Project Manager U.S. Army Corps of Engineers f t 151 Patton Avenue, Room 208 -- Asheville, NC 28801-2714 Subject: Nationwide 14 Permit Application SR 1135 - Shook Cove Road Jackson County 1117-r- State Project No. 14C.050058 (DWQ Minor Permit Fee $200) Dear Mr. Lund: The North Carolina Department of Transportation (NCDOT) is proposing to widen, grade, and pave SR 1135, Shook Cove Road, in Jackson County from the end of pavement for a distance of 3,575 feet. This proposal entails widening and paving the existing gravel road to a standard 18- foot roadway. The proposed improvements of SR 1135 have been identified as necessary maintenance and safety improvements. Funds have been allocated for this project, and NCDOT would like to perform these activities sometime during the 2006-07 paving season. I am sending a straight-line diagram with the proposed erosion control and construction limits along this project. In addition, I am sending a typical section of the road, cross sections, drawings for pipe culvert replacements as well as a marked county map and USGS quad map. We propose to install the new culverts slightly below the existing streambed elevations where bedrock is not encountered to minimize impacts to aquatic habitats and allow the existing stream gradients to remain as unchanged as physically possible. The North Carolina Natural Heritage Database was checked for records of federally threatened and endangered species. There are no records listed for the unnamed tributaries to Tuckasegee River (Bear Lake). Additionally, there are no records for the adjacent watersheds, Kiesee Creek and Turkey Branch. The streams flow to Bear Lake a short distance downstream of the project. The impacts from replacing and extending culverts should be relatively minimal. For these reasons, we believe that there will be "no effect" on threatened and endangered species. 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 erosion control measures daily to ensure sedimentation and erosion is being effectively controlled. If the planned devices are not functioning as intended, they will be immediately replaced with better devices. The rock silt screens and other erosion control devices will be in place prior to pipe culvert construction and will remain in place until the project is stabilized. Impacts to Waters of the United States The unnamed tributaries to Bear Lake are small and are not shown on the topographic map. However, the streams appear to have perennial flow. The streams have well defined channels with sand and silt substrates. The channels lack vegetation. For these reasons, we believe these streams are under the jurisdiction of the U.S. Army Corps of Engineers. In order to construct the project in accordance with our current secondary road standards, it will be necessary to impact waters of the United States in the Little Tennessee River Basin. Specifically, NCDOT is requesting to extend/replace seven metal culverts and perform one channel change in unnamed tributaries to the Tuckasegee River (DWQ Class WS III & B Tr).

Impacts cannot be avoided Culverts must be extended in order to train the necessary width to improve SR 1135 to current NCDOT standards All pipe extensions will be placed below the existing stream bed gradient so natural substrate can be re-established. Page 5 of 9 VIII. 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 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://l12o.enr.state.ne.us/ncwetiands/strm,idc.litmi. 1. 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). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability and to request written approval of mitigation prior to submittal of a PCN.

This road provides access to a public boat launch on Cedar Cliff Lake and to numerous homes in the area. An unnamed tributary to the East Fork Tuckaseigee River crosses this road and runs adjacent to the fill slope on the northeast side of the existing gravel. This will require relocating the stream for approximately 126 feet to accommodate the new fill slope. The attached plan relocates the stream approximately 15 feet to the north east and includes restoring the stream to a reference dimension, pattern, and profile as well as enhancing biological integrity. Project Description The existing stream emerges from a narrow wooded colluvial valley to a cleared Type II valley in the vicinity of the road crossing. The stream is not a blue line on the USGS 7.5 minute quadrangle maps but appears to be perinneal. The existing segment of the stream adjacent to the road is severely impacted by grading and channelization upstream from the road crossing and from road maintenance operations. Plans, profile, and cross sections are attached. Reference Reach The reference reach used is in the Mills River Watershed, located 0.6 miles west of Mills River Campground, 0.45 miles west of the bridge over Mills River, and 429 to 984 feet north of North Mills River Road on an unnamed tributary to Rocky Branch. The reference reach consists of 3 segments of the tributary which are on the same 700'+/- reach of stream. Although the reference reach is in a different watershed, it is similar in valley type, slope, and watershed area. Cross Section No. 3 has a lower width-depth ratio than the other cross sections. This cross section is used primarily as a check on area and flow. Site Maps Location maps of the site and the reference reach are shown on the following pages. Site Plans Plans for the restoration include the plan view showing relative locations of proposed features, a profile view showing grade control, typical sections at specific locations, and details of various structures used for stability. The watershed of the stream to be relocated is primarily forested in the upper reach and is less wooded with residential and farm use in the vicinity of the road. An abandoned field lies beside the stream opposite the road. The stream is connected to a floodplain in the edge of this field at only one location at and below the cross section at station 22+80. The lateral stability of the existing stream is supported by the large woody vegetation and associated root mass. Tendency toward moderate lateral instability at and just below the cross section at station 22+82 will be lessened by the decreased sediment supply from the gravel road to be paved. Vertical instability of the existing stream is evidenced by the increasing bank height over the reach studied. Measures to control this instability in the relocated section include decreased slope between steps that are grade controlled with rock weirs. The lateral stability prediction for the reference reach included factors indicating moderate instability. These were primarily tight meanders due to site constraints and the steep side slopes that originate immediately at the bankfull width. These can be reduced or eliminated in the proposed stream relocation by establishing stable meanders and by constructing a bankfull bench adjacent to steep side slopes as illustrated in the cross section drawing. Rosgen recommends a bankfull bench on the outside of bends of at least 10% to 15% of the bankfull width. The cross section drawing uses 1.2 - 2.0 feet, which is 20% - 33% of the bankfull width. The vertical stability prediction for the reference reach indicated stability with a slight tendency for degradation, however, this tendency was also due to bank height ratio, which will be rectified in the proposed stream relocation. Sediment Transport Entrainment calculations of the reference reach indicated that particles in the range of 150 - 400 millimeters were being transported across the cross sections. The shear stress in the proposed channel at bankfull flow should also transport this size particle. Particle counts were made at each of the 3 cross sections as well as along the length of each of the 3 segments of the reference reach. Velocity determinations were made at each of the three cross sections using local slope. Sediment transport calculations results are supported by visual observations within the stream. The stream bed appeared to be made up of a bimodal distribution. The D84 particle sizes were in the range of .2 mm to 15 mm except for Cross Section No. 2 which had a D84 particle size of 97 mm. The smaller particles were bright while the larger particles of 100 mm to 500 mm were dull and supported moss growth. This indicates that the larger particles were on the upper end of the competence ability of the stream to transport at bankfull flow. The smaller particles are moved regularly down the watershed while the larger cobbles and boulders accumulate from colluvial deposits and are more likely to become imbedded. The proposed stream is designed to transport particles in the range of 250 - 300 millimeters by setting the step spacing close enough to cause a relatively uniformly sloped bankfull height along the reach. Care should be taken to avoid long step spacings which will isolate the slope between steps and result in a local slope that is insufficient to transport sediment particle sizes. Buffer and Planting Requirements Native Grass Seeding And Mulching rate per acre (hectare) will be determined by the Engineer prior to the time of top dressing and the Contractor will be notified in writing of the rate per acre (hectare), total quantity needed, and areas on which to apply the supplemental seed. Minimum tillage equipment, consisting of a sod seeder shall be used for incorporating seed into the soil as to prevent disturbance of existing vegetation. A clod buster (ball and chain) may be used where degree of slope prevents the use of a sod seeder. Mowing: The minimum mowing height shall be 6 inches (150 mm). Native Grass Seeding and Mulching shall be performed in accordance with Section 1660 of the Standard Specifications and vegetative cover sufficient to restrain erosion shall be installed immediately following grade establishment. Stream Bank Reforestation Materials: Stream bank reforestation will be planted in areas designated on the plans and as directed by the Engineer. Type I Stream bank Reforestation shall be live stakes, planted along both stream banks. Coir fiber mat shall be installed on the stream banks where live staking is to be planted as shown on the stream bank typical cross section and in locations as directed by the Engineer. Work includes providing all materials, excavating and backfilling, and placing and securing coir fiber mat. Provide matting to meet the following requirements: 100 % coconut fiber (coir) twine woven into a high strength matrix. Thickness - 0.30 in. minimum. (7.6 mm) Tensile Strength - 1348 x 626 lb/ft minimum (1650.5 x 766.5 kg/m) Elongation - 34% x 38% maximum Flexibility (mg-cm)- 65030 x 29590 Flow Velocity- Observed 11 ft/sec (3.35 m/s) Weight - 20 oz/SY (678 g/SM) Size - 6.6 x 164 ft (120 SY) or (100 SM) "C" Factor - 0.002 Open Area (measured) - 50% Provide wooden stakes 12 in. (300 mm) in length with a notch cut 1 in. (25 mm)from top. Place the matting immediately upon final grading. Provide a smooth soil surface free from stones, clods, or debris which will prevent the contact of the matting with the soil. Take care to preserve the required line, grade, and cross section of the area covered. Unroll the matting and apply without stretching such that it will lie smoothly but loosely on the soil surface. Bury the top slope end of each piece of matting in a narrow trench at least 6 in. (150 mm) deep and tamp firmly. Where one roll of matting ends and a second roll begins, overlap the end of the upper roll over the buried end of the second roll so there is a 6 in. (150 mm) overlap. Construct check trenches at least 12 in. (0.3 m) deep every 50 ft. (16 m) longitudinally along the edges of the matting or as directed by the Engineer. Fold over and bury matting to the full depth of the trench, close and tamp firmly. Overlap matting at least 6 in. (150 mm) where 2 or more widths of matting are installed side by side. Place stakes across the matting at ends, junctions, and check trenches approximately 1 ft. (0.3 m) apart with notch facing up slope. Place stakes along the outer edges and down the center of each strip of matting 3 feet (1 meter) apart. Place stakes along all lapped edges 1 ft. (0.3 m) apart. Refer to details in the plan sheets. The Engineer may require adjustments in the trenching or staking requirements to fit (U o y O ' r` O O O N M r ; O O ' C7 w O r O N 7 CO O = W > r ?7 m C N C') 'IT co v - r r O o O C6 O O C7 - r O (o d r O O N N CO ` r Cf ?

The stream segment which is assessed should represent average stream conditions. In order to perform a proper habitat evaluation the observer needs to get into the stream. All meter readin-s need to be performed prior to walking the stream. When working the habitai index, select the description which best fits the observed habitats and then circle the score. If the observed habitat falls in between two descriptions, select an intermediate score. There are eight different metrics in this index and a final habitat score is determined by adding the results from the different metrics. /?- O.4'S nti?Qs West Stream j/ }- pT Location/Road % j jj5 R i V'eY Counh'_Y?h???1l P?''r?1 ?j 1 .
