Director Division of Water Quality October 1, 2004 Alleghany County Project No. 04-1431 WQ SR 1177 (Tilley Rd) W' T 1 5 2004 APPROVAL of 401 Water Quality Certification DE NR - VU„ T _R QUALITY WETLAN S, N:10 VORMWATER BRANCH Mr. Mike Pettyjohn, P.E. Division Engineer, Division 11 N C Department of Transportation Post Office Box 250 North Wilkesboro, North Carolina 28659 Dear Mr. Pettyjohn: You have our approval, in accordance with the attached conditions and those listed below, to impact 44 linear feet of an unnamed tributary to Piney Fork (34 feet of new pipe and 10 feet of rip-rap) and 0 impacts to Piney Fork for bridge replacement, in order to pave, increase lane width and improve traffic safety on SR 1177 (Tilley Rd) in Alleghany County. The project shall be constructed in accordance with your application dated August 25, 2004 (received August 27, 2004). After reviewing your application, we have decided that this fill is covered by General Water Quality Certification No. 3404, corresponding to the U.S. Army Corps of Engineers Nationwide Permit Number 14. In addition, you should 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 Division of Water Quality (Division) and submit a new application. If the property is sold, the new owner must be given a copy of this approval letter and certifications, 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 remain valid, you must adhere to the conditions listed in the attached certification and any additional conditions listed below. 1. Instream work and land disturbance within the 25 foot wide buffer zone are prohibited during the brown and brook trout spawning season of October 15 through April 15 to the egg and fry stages of trout from off-site sedimentation during construction. 2. Piney Fork and its tributaries are classified as Trout waters. NCDOT shall strictly adhere to the 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)] throughout design and construction of the project.

October 1, 2004 DWQ# 04-1431 Page 2 3. Best Management Practices for bridge demolition shall be followed. Once the old bridge is removed, that stream and floodplain area should be restored to natural geomorphic conditions. Stream banks should be restored using native species. Stream banks can be revegetated with silky dogwood, rhododendron, dog hobble, red maple, silky willow, tag alder, black willow, sycamore, or other native woody species to provide long term bank stability and stream shading. Note that silky dogwood, silky willow and black willow can be planted as live stakes collected during the dormant growing season. Cuttings should be randomly planted and done on 4 foot centers from the waters edge to the top of the bank. Trees should be planted on 10-12 foot centers. Stream banks in these areas should also be seeded with an approved wetland seed mix or temporary crop of wheat or rye. 4. 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. d. The reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. 5. 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. 6. 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 completion of the project. 7. Riparian vegetation must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. 8. Stormwater should 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 sheet flow. 9. Where practicable, 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 in 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. These measurements must be based on natural thalweg depths. 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. All waters must flow through without freefalling or damming on either end of the culverts during low flow conditions, to maintain aquatic life and/or fish passage. 10. The culvert at station 31+30 may remain perched after replacement due to on-site slopes. If appropriate, an energy dissipater pad should be installed to provide a base flow channel to facilitate aquatic life passage. Riprap used must not interfere unnecessarily with aquatic life movement during low flows. Mr. Mike Pettyjohn, P.E. October 1, 2004 DWQ# 04-1431 Page 3 11. The dimension, pattern and profile of the stream above and below the crossing should not be modified by widening the stream channel or reducing the depth of the stream. 12. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 13. Use of rip-rap for bank stabilization is to be minimized; rather, native vegetation is to be planted when practical. If rip-rap is necessary, it must be limited to the stream bank below the high water mark, and vegetation must be used for stabilization above high water. Any rip-rap used must not interfere with aquatic life passage during low flow conditions. 14. If concrete is used, work must be accomplished so the wet concrete does not contact the stream water. This will lessen the chance of altering the stream's water chemistry and causing a fish kill. 15. Heavy equipment must be operated from the banks rather than in the stream channel in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream. 16. 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. 17. 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 culverts. 18. Temporary dewatering sites must be restored to preexisting conditions unless more natural geomorphic conditions can be provided. 19. All work shall be performed during low flow conditions. 20. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certification of Completion Form" to notify DWQ when all work included in the 401 Certification has been completed. The responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the Division of Water Quality upon completion of the project. 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.

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. By utilizing the erosion control measures as shown in the attached drawings adverse impacts to streams in the area will be minimized. Since this is an existing roadway, the stream impacts cannot be avoided. However, the replacement pipe length will be the minimum needed to safely construct the paved roadway. All appropriate BMPs will be used during, construction Page 7 of 12 Q 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 NCWRP 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 littp://h2o.enr.state.nc.us/ncwetlands/sirmgide.html. 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 ofI'site), 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.
