Ross Jr., Secretary North Carolina Department of Environment and Natural Resources p ~= - Alan W. Klimek, P.E. Director Division of Water Quality October 10, 2006 Madison County DWQ Project No. 061544 NCSR 1379 (Arvil Gosnell Road) APPROVAL of 401 Water Quality Certification with Additional Conditions Mr. J. J. Swain, Jr., P.E. Division Engineer N C Department of Transportation Post Office Box 3279 Asheville, North Carolina 28802 Dear Mr. Swain: You have our approval, in accordance with the attached conditions and those listed below, to impact 15 linear feet in Sprinkler Branch, replace three (3) existing culverts in Sprinkler Branch and a culvert in an unnamed tributary to Sprinkler Branch and temporary dewatering (15 linear feet of new pipe, replacement of four (4) existing pipes and temporary dewatering), in order to make improvements to NCSR 1379 (Arvil Gosnell Road) in Madison County. The project should be constructed in accordance with your application dated September 19, 2006 (received September 22, 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 211 .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.

J. Swain, Jr., P.E. October 10, 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 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. 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 prior to discharging directly into streams. Mowing of existing vegetated buffers is strongly discouraged. 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. 8. 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. 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 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. 10. 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. 11. 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. 12. Rock check dams at culvert outlets should be removed at project completion to avoid impeding aquatic life movement. 13. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise authorized by the certification. 14. A copy of this Water Quality Certification shall be posted on the construction site at all times. In addition, the Water Quality Certification and all subsequent modifications, if any, shall be maintained with the Division Engineer and the on-site project manager. 15. The outside bdffer, wetland or water boundary located within the construction corridor approved by this authorization shall be clearly marked by high visible fencing prior to any land disturbing activities. Impacts to areas within the fencing are prohibited unless otherwise authorized by this certification. Mr. J. J. Swain, Jr., P.E. October 10, 2006 Page Three 16. 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. 17. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. 18. 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. 19. No rock, sand or other materials shall be dredged from the stream channel, except where authorized by this certification. 20. 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. 21. 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. 22. 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. 23. 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.

Arvil Gosnell Road is currently a 14-16 feet wide gravel road. Division of Highways plans to pave the road 18 feet wide and increase the typical section. Grading will be light. We propose to extend two (2) pipe culverts on Sprinkler Branch. In addition, we plan to replace four (4) pipe culverts on Sprinkler Branch and an Unnamed Tributary (UT) to Sprinkler Branch with no extension of the pipes. Total culvert extensions will be 15 linear feet. Sprinkler Branch is an approximately 2-4 foot wide creek with riffle/pool habitats, cobblestone and bedrock substrate, and bed/bank features. The UT of Sprinkler Branch at Site 6 is a 6" wet ditch with sand and vegetative substrate. No stream relocation will be performed for the project. Existing channel morphology will be maintained upstream and downstream of the culverts. The culverts will be placed below existing streambed elevation. Riparian vegetation will be reestablished along P + Mr. David Baker Page -2 SR 1379, Madison County September 19, 2006 disturbed areas associated with the culvert extensions. Stormwater will be diverted through grass-lined ditches or vegetated buffers prior to entering streams. No effect on federally listed species (threatened or endangered) or their habitats is anticipated. As a part of the 401 Certification process, a copy of the application will be forwarded to the NC State Historic Preservation Office as required by Section 106 of the National Historic Preservation Act of 1966 and GS 121-12(a). By copy of this letter, we request David McHenry, North Carolina Wildlife Resources Commission Coordinator, to comment directly to the Corps concerning the permit request.

Isolated Waters Do any isolated waters exist on the property? ? Yes ® No Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. Page 5 of 9 8. Pond Creation If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ? uplands ? stream ? wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: Size of watershed draining to pond: Expected pond surface area: VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be 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. The existing secondary road must be improved to meet current safety standards for paved roads. The nine culvert extensions requested are the minimum necessary to establish an appropriate typical section for the roadway. Pipes that are to be replaced are damaged Riparian vegetation will be established on disturbed areas associated with the project construction. 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 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 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. Page 6 of 9 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 httv://h2o.enr.state.nc.us/ncwetlands/strmp-ide.htm]. 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. We do not feel that mitigation is warranted due to the minimal impacts of the ripe culvert extensions Additionally paving of the roadway should eliminate sedimentation from fines associated with gravel roadway. If required we propose to utilize the Ecosystem Enhancement Program (EEP) for the mitigation requirements for the proposed impacts. NCDOT will be coordinating with the EEP to obtain the Wropriate mitigation credits if required. 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 written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form. For additional information regarding the application process for the NCEEP, check the NCEEP website at http•//h2o.enr.state.nc.us/wrp/index.htrn. If use of the NCEEP is proposed, please check the appropriate box on page five and provide the following information: Amount of stream mitigation requested (linear feet): Amount of buffer mitigation requested (square feet): Amount of Riparian wetland mitigation requested (acres): Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): IX.

Temporary stone ditch checks shall be installed as soon as ditch line is established. Pipe outlet and inlet protection will be done as soon as the pipe is installed. Silt basins (Type B) will be constructed to the dimension of nine feet by three feet by two feet unless otherwise noted on plans. (See SB-9 on dimension sheet) Seeding and other permanent erosion control measures are to be implemented as soon as practical. Temporary rock silt checks (Type B) will be spaced as required by percent of grade. = _ - - PIPE INSTALLATION NOTES 1) Install erosion control devices. In streams, where necessary, rock silt screens will be used. 2) Remove material and existing pipe while limiting, as much as possible, material and sediment from entering the stream and/or escaping from the project. 3) Prepare pipe foundation while again taking care to limit, as much as possible, material and sediment from entering the stream and/or escaping from the project. Where possible, new grade will be below the existing streambed. If needed, bedding material will be clean stone. 4) Place the new pipe and compact backfill. 5) 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. 6) Establish permanent vegetation as soon as possible. PIPE OUTLET ENERGY DISSIPATOR: • • . A pipe outlet energy dissipator shall be used at pipe outlets to slow the water velocities when it exits the pipe and flows out ditched or natural waterways. It is an apron of stone of a sufficient thickness to protect the outlet area from scouring out and causing off-site sedimentation damage. Pipe outlet energy dissipators should be built according to the guideline chart shown on page VIII-3 of this manual. AREAS OF USE: ! • Outlets of pipes and culverts to prevent scouring.. DESIGN CRmRIA: • In accordance with chart on page VIII-3. • Filter fabric, or six inch layer of gravel, shall be used under stone.
