Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality December 9, 2005 DWQ Project # 05-2051 Buncombe County Jon Creighton Buncombe County Government 205 College Street Asheville, NC 28801 Subject Property: Willow Creek (Aubrey Wells) - EWP Approval of 401 Water Quality Certification with Additional Conditions Dear Mr. Creighton: You have our approval, in accordance with the attached conditions and those listed below, to place fill within or otherwise impact 1,100 feet of streams for the purpose of streambank stabilization at the subject properties, as described within your application received by the N.C. Division of Water Quality (DWQ) on November 30, 2005. After reviewing your application, we have decided that the impacts are covered by General Water Quality Certification Number(s) 3376 (3376). The Certification(s) allows you to use Nationwide Permit(s) 37 when issued by the US Army Corps of Engineers (USACE). In addition, you should obtain or otherwise comply with any other required federal, state or local permits before you go ahead with your project including (but not limited to) Erosion and Sediment Control, Non-discharge, and stormwater regulations. Also, this approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA Permit. This approval is for the purpose that you described in your application. If you change your project beyond the activities authorized below, you must notify us and you may be required to send us 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 conditions. If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). This approval requires you to follow the conditions listed in the attached certification and any additional conditions listed below. The Additional Conditions of the Certification are: 401 Wetlands Certification Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786/ FAX 919-733-68931Internet http://h2o.enr. state. no. us/ncvvetlands North Carolina AVattrra!!y An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper Buncombe County: Page 2 of 6 December 9, 2005 1. Impacts Approved The following impacts are hereby approved as long as all of the other specific and general conditions of this Certification (or Isolated Wetland Permit) are met. No other impacts are approved including incidental impacts: Amount Approved (Units) Plan Location or Reference Stream 1,100 feet Willow Creek 2. Erosion & Sediment Control Practices 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. 3. No Waste, Spoil, Solids, or Fill of Any Kind 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 Pre-Construction Notification. 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. r Buncombe County: Page 3 of 6 December 9, 2005 4. No Sediment & Erosion Control Measures w/n Wetlands or Waters 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 Resources has released the project. 5. Certificate of Completion Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer Rules, and any subsequent modifications, the applicant is required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650. 6. Sediment and erosion control measures must be implemented prior to construction and maintained on the sites to minimize sediment in downstream areas. Seeding for a temporary cover of wheat, millet, or similar annual grain or permanent herbaceous cover should occur on all bare soil within five (5) days of ground disturbing activities to provide long-term erosion control. The projects should be accomplished in stages instead of leaving large tracts exposed to further storm events. Erosion control matting should be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas, unless authorized under Division of Land Resources Erosion and Sediment Control approval. Matting should be secured in place with staples, stakes, or, wherever possible, live stakes of native trees. Straw mulch and tall fescue should not be used in riparian areas. In addition, because of an anticipated difficulty in establishing ground cover during the winter, reseeding should be conducted, as necessary, in the spring-time with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet or other grain. 7. Only clean, large, angular rock, large woody material, or other natural stream design materials and techniques should be used for bank stabilization. Rock should not be placed in the stream channel in a manner that constricts stream flow or that will impede aquatic life movements during low flow conditions. Filter cloth should be placed behind large rock that is used for bank stabilization. Properly designed rock vanes should be constructed wherever appropriate on bank stabilization and channel realignment stream reaches to improve channel stability and to improve aquatic habitat. Root wads should be installed low enough in the bank so that a significant portion (at least one-third) the root wad is inundated during normal flows. 8. The channel must be restored to a more stable condition. However, under no circumstances should river rock, sand or other materials be dredged (excavated) from the stream channel under authorization of this permit except, if necessary, in the immediate vicinity of the eroding banks for the explicit purpose of anchoring stabilizing or flow/grade control structures or for re-establishing the natural and more stable stream channel dimensions. Streambed materials are unstable in flowing-water situations and are unsuitable for bank stabilization. Stream dredging Buncombe County: Page 4 of 6 December 9, 2005 has catastrophic effects on aquatic life and disturbance of the natural form of the stream channel can cause downstream erosion problems. The natural dimension, pattern, and profile of the stream upstream and downstream of the permitted area should not be modified by widening the stream channel or changing its depth. 9. Stabilization measures should only be applied on or near existing erosion sites, leaving other stable stream bank areas in a natural condition. Grading and backfilling should be minimized and tree and shrub growth should be retained where possible to ensure long term availability of stream bank cover for aquatic life and wildlife. Backfill materials should be obtained from upland sites except in cases where excess stream bed materials are available. Berms are not permitted because they block the floodplain, constrict and accelerate flood flows, and often fail or impede drainage during large flood events. 10. Repairs to eroded banks should be conducted in a dry work area where possible. Sandbags or other clean diversion structures should be used where possible to minimize excavation in flowing water. Channel realignments should be constructed by excavating the new channel from downstream to upstream before connecting it to the old channel. 11. Heavy equipment should be operated from the bank whenever possible. All mechanized equipment operated near surface waters should be inspected and maintained regularly to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids or other toxic materials. Equipment used in stream channel must be clean, new or low hour equipment. 12. Riparian Zone Replanting Replanting of vegetation within disturbed areas located within 25 feet of the streambank associated with any land disturbing activity, repair, replacement and/or maintenance must be done in a manner consistent with the Guidelines for Riparian Buffer Restoration immediately following construction. (Please see: http://h2o.enr.state.nc.us/wrp/pdf/buffers.pdf ) 13. Monitoring The Permittee shall examine the stabilization work done under this Certification on an annual basis for three (3) years following the completion of the restoration efforts. This field evaluation should note the condition and stability of the measures installed and how well the repair is holding up. A written report must be provided to DWQ's Asheville Regional Office by June 15t of each year. The report must describe inspection results, include digital photographs, list the date of inspection, and describe any needed repairs or corrections. 14.The permittee will provide on-site supervision of stability work including, but not limited to bank re-sloping, in-stream structure placement, and riparian zone re- establishment, by an appropriately trained individual. ti 15. If pasture along the stream is to be used for grazing, the permittee must inform the appropriate landowners that cattle should be prohibited from damaging riparian areas and from de-stabilizing the stream banks and channel. Buncombe County: Page 5 of 6 December 9, 2005 16. Diffuse Flow All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at non-erosive velocities through the protected riparian zones such that it will not re-concentrate before discharging into a stream. 17. Water Quality Certification Notifications The permittee must provide a copy of this issued Water Quality Certification and attached cover letter to each property owner where the approved work will be performed. 18.Turbidity Standard The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 213. .0200. Appropriate sediment and erosion control practices must be used to meet this standard. Violations of any condition herein set forth may result in revocation of this Certification and may result in criminal and/or civil penalties. The authorization to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application and as authorized by this Certification, shall expire upon expiration of the 404 or CAMA Permit. If you do not accept any of the conditions of this Certification (associated with the approved wetland or stream impacts), 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. Buncombe County: Page 6 of 6 December 9, 2005 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 Cyndi Karoly in the Central Office in Raleigh at 919-733-9721 or Mr. Kevin Barnett in the DWQ Asheville Regional Office at 828-296-4657. Sincerely, Alan W.

BUNCOMBE COUNTY SOIL AND WATER CONSERVATION DISTRICT 155 Hilliard Avenue, Suite 204 (828) 250-4785 Asheville, NC 28801 FAX: (828) 251-4908 MEMORAIVD UM DATE: November 7, 2005 TO: US ACOE, NC DENR-DWQ and NC WRC FROM: Gary Higgins, Director - Buncombe County SWCD REGARDING: Permit application for the Aubrey Wells Emergency Watershed Protection Site I have enclosed the application to obtain the necessary permits and other participation from the agencies listed above for Emergency Watershed Protection program work on the Aubrey Well's farm site. James Coman, Planner in the Buncombe County Planning Department, has signed the permit application for Jon Creighton, the Buncombe County Assistant County Manager, as he is out of town for an extended period of time. Mr. Jeff Young, NCDENR Division of Soil & Water Engineer, has been flooded with design requests from all western counties involved in EWP. He has assured us that he will have the designs for this project complete by next week. We are submitting the application prior to the plans being complete, in order to get the ball rolling. Plans will follow as soon as we get them from Mr. Young, possibly by this Friday. This project should involve the following activities: removal of woody/earthen debris; partially restoring channel dimension by back filling part of the area washed out; addition of rock structures; realignment of the channel; and revegetating the banks area. Work will be done from the bank a much as possible, with protective barriers being used during placement of soil/rock backfill, but due to the stream width and bank height, some work in the stream will have to take place. The goal is to return the stream to it's proper cross sectional area and location, stabilize the stream banks, and revegetate. We expect that a dump truck, track hoe and small dozer will be the equipment used at this site. This is a project funded by the USDA - Emergency Watershed Protection Program and the NCDENR 401 fees have been waived.

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. This site has moderate slopes on one side of the creek and a very steep bank on the other side. Work will only be able to be completed from the cornfield side of the creek. Work will be completed in the dry as much as possible, but some work in the creek is anticipated, especially during the realignment. Stone / rock used will be clean and placed from the bank wherever 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 equal to one acre of impacts to Page 9 of 12 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.

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. This site has moderate slones on one side of the creek and a verv_ steep bank on the other side. Work will only be able to be completed from the cornfield side of the creek. Work will be completed in the dry as much as possible, but some work in the creek is anticipated, especially during the realignment. Stone / rock used will be clean and placed from the bank wherever 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 equal to one acre of impacts to Page 9 of 12 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 http://h2o.enr.state.nc.us/ncwetlands/strmgide.htmi. 1.

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. This site has moderate slones on one side of the creek and a verv steep bank on the other side. Work will only be able to be completed from the cornfield side of the creek. Work will be completed in the dry as much as possible, but some work in the creek is anticipated, especially during the realignment. Stone / rock used will be clean and placed from the bank wherever 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 equal to one acre of impacts to Page 9 of 12 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 http://h2o.enr.state.nc.us/ncwetIands/stnngide.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 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. None 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP).
