B RANCH July 22, 2005 Avery County DWQ Project No. 051260-MA 11008R NCSR 1370 (Avery County High School Road) APPROVAL of 401 Water Quality Certification with Additional Conditions Mr. Mike Pettyjohn, P.E. Division Engineer 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 18 linear feet of an unnamed tributary to Mill Timber Creek and 10 linear feet of an unnamed tributary to Kentucky Creek and temporarily dewater both streams in order to widen and make safety improvements to NCSR 1370 (Avery County High School Road) in Avery County. The project must be constructed in accordance with the application dated July 8, 2004 (received July 13, 2005), including the environmental commitments made in the application letter. 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 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.

July 22, 2005 Page Two 'L d. The 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. In-stream work and land disturbance within the 25-foot wide buffer zone is prohibited during the trout-spawning season of October 15 through April 15 to protect the egg and fry stages of trout from off-site sedimentation during construction. 5. Stringent sediment and erosion control measures should be implemented prior to any ground disturbing activities to minimize impacts to adjacent and downstream aquatic resources. Temporary or permanent herbaceous vegetation should be planted on all bare soil within five (5) days of ground disturbing activities in the riparian buffer to provide long-term erosion control. The WRC encourages the NCDOT to utilize onsite vegetation and materials for streambank stabilization, when practicable. 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, 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. 7. 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, replaced and re- installed correctly, unless demonstrated that this is topographically unfeasible. 8. Removal of vegetation at stream crossings and adjacent to streams should be minimized. Native trees and shrubs (e.g. rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) should be planted along the streambank to reestablish the riparian zone and provide long-term erosion control in the vicinity of the road crossings and along the streams within the dedicated rights of way. 9. Heavy equipment must be operated from the high ground rather than in the wetland in order to minimize disturbance to vegetation and compacting soils. 10. 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. 11. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to wetlands or surface waters is strictly prohibited. 12. Upon completion of the project, any temporary impacts from sediment and erosion control practices should be removed and the affected areas restored to the extent practicable. 13. The dimension, pattern and profile of the stream, above and below the culverts, should not be modified by widening the stream channel or reducing the stream depth. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 14. 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. 15. Excavation of the stream crossings and relocations 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. 16. 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. 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. 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. Mike Pettyjohn, P.E. July 22, 2005 Page Three 18. 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 culvert extensions. 19. All work shall be performed during low flow conditions (below bankfull). 20. 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.

Aven- Page 2 July 8, 2005 structures are in place, the impervious dikes will be removed and preconstruction streambed elevations will be restored. Construction of this project will require impacts to waters of the United States in the French Broad and Catawba basins. The wet pipe located at station 13+00 carries an unnamed tributary to Mill Timber Creek (C;Tr), Catawba Basin. The wet pipe located at station 49+00 carries an unnamed tributary to Kentucky Creek (Class: WS-IV; Tr), French Broad Basin. This project was reviewed for the presence of threatened and endangered species on July 8, 2005. This project will have no effect on any federally listed endangered plant or animal species. Historic compliance work will be scheduled and concurrence with the State Historic Preservation Office will be obtained if required. The proposed project should not remove or degrade existing water quality uses. Pipe sizes used will be the minimum necessary to create a safe roadway. All pipes with a slope greater than 6% will remain perched and an energy dissipator pad will be installed at the pipe outlet. By utilizing all appropriate erosion control measures, downstream water quality standards will be protected. All appropriate BMPs will be used during construction. Attached is a Preconstruction Notification Form, plan sheets with proposed erosion control measures, a marked county map, a marked topography map and photographs.

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 appropriate erosion control measures, 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 lengths will be the minimum needed to safely construct the widened roadway. All appropriate BMPs will be used during 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 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. Page 7 of 12 V 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 httl2://h2o.enr.state.nc.us/ncwetiands/strmgide.htmi. 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. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that you would like to pay into the NCWRP. Please note that payment into the NCWRP must be reviewed and approved before it can be used to satisfy mitigation requirements. Applicants will be notified early in the review process by the 401/Wetlands Unit if payment into the NCWRP is available as an option.
