Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality July 21, 2005 Macon County DWQ Project No. 051332 NC SR 1310 (Wayah 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 100 linear feet of Wayah Creek (100 linear feet of rip rap and ring nets), in order to repair the failing retaining wall adjacent to NCSR 1310 (Wayah Road) in Macon County. The project should be constructed in accordance with your application dated July 14, 2005 (received July 20, 2005), including the environmental comments made in the application letter. After reviewing your application, we have decided that this fill is covered by General Water Quality Certification No. 3399, corresponding to the U.S. Army Corps of Engineers Nationwide Permit Number 13. 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 approval will expire with the accompanying 404 Permit unless otherwise specified in the Water Quality Certification. 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 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.

B. Setzer, P.E. July 21, 2005 Page Two d. Any reclamation measures and impl?rrie ntation 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. In-stream work should not be performed during the trout-spawning season of October 15 through April 15. 5. The NCDOT shall use Best Management Practices for the Protection of Surface Waters (NCDOT August 2003) and Sedimentation and Erosion Control Guidelines for 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 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. The rocks placed on the bank should be backed with filter cloth and should be clean and sediment free. 10. Heavy equipment must be operated from the banks rather than in the stream channel in order to minimize sedimentation and to reduce the likelihood of introducing other pollutants into the stream. 11. All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 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 the construction, a dry work area should be maintained to prevent direct contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete shout not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and fish kills. 15. The presence of equipment in the channels must be minimized. 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. 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. Mr. J. B. Setzer. P.E.

Temporary shoring using soil nails and a shotcrete facing will be required to safely remove the existing wall. The proposed improvements of SR 1310 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 2005 paving season. I am sending a toe scour protection installation detail as well as a marked county map and USGS quad map. We propose to install the toe scour protection slightly above the normal stream elevation 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.

Temporary shoring will be used so that work can be done from stream bank Therefore impacts will be minimized to the greatest extent possible 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 equalIto one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to ' perennial streams. Page 6 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 htti)://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 approN al of mitigation prior to submittal of a PCN.
