Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality April 6, 2006 Macon County DWQ Project No. 060496 NCSR 1710 (Rich Gap Road) APPROVAL of 401 Water Quality Certification with Additional Conditions Mr. J. 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 14 linear feet in an unnamed tributary to Big Creek (14 linear feet of new pipe and temporary dewatering), in order to make improvements to NCSR 1710 (Rich Gap Road) in Macon County. The project should be constructed in accordance with your application dated March 22, 2006 (received March 27, 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. 1. 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. 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 proj ect. 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.

B. Setzer, P.E. April 6, 2006 Page Two d. Any reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. . 2. 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 Preconstruction Notice Application. 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. 3. 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 Quality has released the project. 4. Culverts that are less than 48-inch in diameter should be buried to a depth equal to or greater than 20% of their size to allow for aquatic life passage. Culverts that are 48-inch diameter or larger should be buried at least 12 inches below the stream bottom to allow natural stream bottom material to become established in the culvert following installation and to provide aquatic life passage during periods of low flow. This may require increasing the size of the culvert to meet flow conveyance requirements. If any of the existing pipes are perched, they shall be removed and replaced, and re-installed correctly, unless demonstrated that this is topographically unfeasible. 5. The NCDOT shall use Design Standards in Sensitive Watersheds [15A NCAC 4B .0124 (a)-(e)]. 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 this work, should not be modified by widening or narrowing the stream channel or reducing the stream depth. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 7. Stormwater shall be directed to vegetated buffer areas, grass lined ditches or other means appropriate to the site for the purpose of pre-treating stormwater runoff, and must not be routed directly into streams. Mowing of existing vegetated buffers is strongly discouraged, so that they may be utilized for stormwater diffuse flow. 8. Riparian vegetation should be preserved to the extent possible. Native trees and shrubs (e.g. Rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) should be restored wherever possible along the repaired slope and streambank to reestablish the riparian zone and to provide long-term erosion control. 9. 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 stream channels in such a manner that it impedes aquatic life passage. 10. Heavy equipment should be operated from the bank rather than in the stream channels in order to minimize sedimentation and to reduce, the likelihood of introducing other pollutants into the stream. This equipment should be inspected daily and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 11. Rock check dams at culvert outlets should be removed at project completion to avoid impeding aquatic life movement. 12. Excavation in the stream channel should be conducted in the dry, if possible. Sandbags, cofferdams, flexible pipe or other diversion structures should be used to minimize excavation in flowing water. 13. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is strictly prohibited. 14. If concrete is used during culvert 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-fish kills. 15. Under no circumstances must rock, sand or other materials be dredged from the wetted stream channel under authorization of this permit, except in the immediate vicinity of the bank stabilization work. In-stream dredging has catastrophic effects on aquatic life, and disturbance of the natural form of the stream channel will likely cause downstream erosion problems, possibly affecting other landowners. Mr. J. B. Setzer, P.E. April 6, 2006 Page Three 16. 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. 17. All work shall be performed during low flow conditions (below bankfull). 18. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certificate of Completion " form to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall complete the attached form and return it to the Transportation Permitting Unit of the NC Division of Water Quality upon completion of the project. The NCDOT is strongly advised to send in photographs upstream and downstream of each structure to document correct installation. 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. If you have any questions, please telephone Mr. Mike Parker of the Asheville Regional Office at 828.296.4500.

Rich Gap Road, in Macon County. This proposal entails widening and paving the existing gravel road to a standard 18-foot roadway. The proposed improvements of SR 1710 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 paving season. I am sending a pipe installation detail as well as a marked county map and USGS quad map. Vde propose to install a new culvert 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. No threatened or endangered species are known to be present in or near the project area: therefore, no significant impacts are anticipated from project construction. 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.

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. Roadwav features were desiened not to exceed North Carolina's minimum secondary roadway standards. Therefore, impacts were minimized to the extent possible, including_pi1) lengths. 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 Page 6 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). 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.
