Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality July 25, 2005 Subject Property: Shooting Creek EWP (Jack Shook) DWQ Project # 05-1296 Clay County 912@120WLRI AUG 1 - 2005 ly dENR - L1/ATER ttUdl1TY Approval of 401 Water Quality Certification with Additional Con?F?STORMWqTFRBUXH Dear Mr. Leek: , You have our approval, in accordance with the attached conditions and those listed , below, to place fill within or otherwise impact 300 feet of streams for the purpose of streambank stabilization and woody debris removal / trash removal at the subject properties, as described within your application received by the N.C. Division of Water Quality (DWQ) on July 14, 2005: After reviewing your application, we have decided that the impacts are covered by General Water Quality Certification Number(s) 3367 (3367). ! The Certification(s) allows you to use Nationwide Permit(s) 37 when issued by the US Army Corps of Engineers (USACE). In addition, you shoutd obtain or otherwise comply i with any other required federal, state or local permits before you go ahead with your I 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. (Nothing in this approval should be interpreted as giving permission to remove bedload material from the existing channel, nor allowing for the construction of berms which would not allow the stream access to it's floodplain.) As "stable" and "pre-storm" are not interchangeable terms, all work must be to ensure stability, regardless of channel location. Additionally, channels cannot be returned to it's pre-storm location unless there is documented instability is submitted and approved as part of the application package. If you change your project beyond the approval here, 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. 401 WeUands Certification Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 1321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-17861 FAX 919-733-6893 / I ntemeL htto://h 20. en r. state. nc. us/n cwetla nds EN::. .an Equal OppoRunitylAffirmative Action Employer- 50% Recycled/10°/a Post Consumer Paper Clay County: " Page 2 of 6 July 25, 2005 The Additional Conditions of the Certification are: 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 300 feet Shootin 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 Contro! 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. u Clay County: Page 3 of 6 July 25, 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 wetiands 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. Construction in this creek and disturbance within a 25-foot trout buffer, where applicable, should be avoided during the October 15 to April 15 trout spawning period to avoid adverse effects of sediment on eggs and larvae, where applicable. However, Wildlife Resources Commission will not object to construction of Natural Resources Conservation Service "urgent and compelling" sites during the spawning , period provided these projects are, to the extent appropriate and practical, constructed by: (1) using flow diversion structures such as sand bags, (2) placing ! large-sized rock toes and filter cloth backing for stabilization sites before backfilling, and (3) excavating new channel alignments in dry areas. Construction at the other non"urgent and compelling" sites should not occur during the spawning period to minimize the potential adverse effects of multiple construction activities on trout resources in this creek. 7. 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. 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. Clay County: _ Page 4 of 6 July 25, 2005 ? 8. 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. 9. The channel should be restored to a more stable condition. However, under no circumstances should river rock, sand or other materials be dredged 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 reestablishing the natural and more stable stream channel dimensions. Stream bed materials are unstable in flowing-water situations and are unsuitable for bank stabilization. In stream dredging 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. 10. Stabilization measures should only_ be applied on or near existing erosion sites, leaving other stable stream bank areas m 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 should not be permitted because they block the floodplain, constrict and accelerate flood flows, and often fail and sometimes impede drainage during large flood events. 11. 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. 12. 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. 13. Disturbed stream banks and a 25-foot vegetated zone, or the widest width that is practical under the site conditions, should be restored along the construction sites to natural riparian conditions with native trees and shrubs (e.g., silky dogwood, rhododendron, dog hobble, red maple, silky wiltow, tag alder, black willow, sycamore) to provide long-term bank stability and stream shading. Note, silky dogwood, silky willow and black willow can be planted as live stakes collected during the dormant growing season. Cuttings should be randomly planted on four (4) foot centers from the waters edge to the top of the bank. Trees should be planted on ten (10) to twelve (12) foot centers. Stream banks in these areas should also be r Clay County: Page 5 of 6 July 25, 2005 seeded with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet or other grain. 14. If pasture along the stream is to be used for grazing, a fence must be constructed outside of the riparian zone and the stream to prevent livestock from entering these areas. 15. 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. If this is not possible, it may be necessary to provide stormwater facilities that are considered to remove nitrogen. This may require additional approval from this Office. 16. Riparian Zone Replanting Replanting of vegetation within disturbed areas located within 30 feet of the streambank associated with any land disturbing activity, repair, replacement and/or maintenance must be done in a manner consistant with the Guidelines for Riparian Buffer Restoration immediately following construction. (Please see attached.) 17. eed Notifications Deed notifications or similar rnechanisms shall be placed on all retained jurisdictional wetlands, waters and protective woody riparian zones in order to assure compliance for future wetland, water and buffer impact. These mechanisms shall be put in place prior to impacting any wetlands, waters and/or buffers approved for impact under this Certification Approval and Authorization Certificate. A sample deed notification can be downloaded from the 401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. The text of the sample deed notification may be modified as appropriate to suit to this project. ' 18. Turbidity Standard The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 2B. .0200. Appropriate sediment and erosion control practices must be used to meet this standard. 19. No Sediment and Erosion Control Measures in Wetlands 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 or locally delegated program has released the project. ulay Lounly: Page 6 of 6 July 25, 2005 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.

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. LJSACE - 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 aze 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 similaz functions and values, prefera.ble in the same watershed. . If mitigation is required for this pmject, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing.

Prepared for: Clay County 55 Riverside Circle Hayesville, NC 28904 June 3, 2005 Prepared by 4r-, MULKEY Shooting Creek - Shook Site Clay County, NC 1.0 INTRODUCTION ` This emergency watershed protection and xehabilitation plan addresses proposed channel improvements to Shooting Creek in Clay County, North Carolina. The plan is being completed in conjunction with an Emergency Watershed Pxotection (EWP) grant provided by the Natural Resources Conservation Service for the Shooting Creek watershed. The project area covers approxitnately 480 linear feet of Shooting Creek on the Jack Shook property. Specifically, the project area is situated south of US 64 approxitnately eight miles east of Hayesville, NC (see attached vicinity map). Landuse throughout the study area is predominately rural. Mulkey Engineers and Consultants (Mulkey) was retained by Clay County to design and oversee the irnplementation of emergency stabilization techniques using natural channel design methodologies. Implementation is planned for July and August 2005. Shooting Cxeek is located within the Hiwassee River Basin in westem North Carolina. It is part of USGS Basin 0600002 and Subbasin 04- OS-01. The Shooting Creek watershed originates along the southeastern face of Chunky Gal Mountain near the Clay/Macon County Line and flows in a westexly direction a p pxo.Yimatel y six miles before em p tyin g into ?1 - ? ? Chatuge Lake. According to the NC Division of Water Quality (NCDWQ> 2002)> watex ?`'?? ?- ??•?. quality in this subbasin is Good. The headwaters of Shooting Creek are xvithin the =? --?-?- _- - Nantahala National Forest and are somewhat undisturbed, due to slope constraints. However, once the slopes begin to decrease, disturbance begins to become evident. A4ost of the disturbances are the result of development and agricultuxal practices, which have negatively affected the stream system. The minimal riparian zones throughout these areas have also added to an increase in sedimentation. According to NCDWQ, sedimentarion in ' Shooring Creek was noted in the 1997 basin plan. Although the stream received a Good classificarion in 1999, DWQ biologists noted eYCessive sedimentation in the pools and sevexe bank erosion. The Shooting Cxeek arm of the lake is almost completely full of sediment (NCDWQ, 2002). Recent flooding attributed to the heavy rain events encountered during the fall of 2004 have only exacerbated the ovetall problems. 2.0 OBJECTIVE The objective of this project is to reduce erosion and sedimentarion originating through this reach and improve the overall habitat values. This objective Nvill be met by establishment of xock structures (xefeYred to as vanes) within noted pxoblem areas to divert the shear stresses away from the erocling streambanks. This project is being funded and implemented as Emergency Watershed Protection and Rehabilitauon (EWP) through a grant ftom the Natural Resources Conservation Service (NRCS). Natural channel design methodologies will be unplemented to maxunum extent pxacticable to ensure the channel dimension, should avexage approximately 171.9 square feet along the riffle sections of this channel. The bankfull width and mean depth should average approximately 58.9 feet and 2.9 feet, respectively. The bankfull discharge is estimated at approximately 1,021.5 cubic feet per second. 2. The contractor will begin by removing existing center bar along the upstream portion of the site and redefine the thalweg near the center of the channel. The material will be repositioned along either side of the channel, staying consistent within the avexage proposed channel cross sectional area. 3. Boulders will be placed within a secondary channel to prohibit low flows from entering the area along the outside of the meanderbend. During higher flows, this axea tends to function as a large center bar with channel stresses being pushed along the outside of the channel. Geotextile fabric and excavated material will be placed along the upstream edge of these boulders to restrict fines and other material from passing through any gaps between the rocks. The downstream confluence of this channel with Shooting Creek will remain open primarily for aquatic habitat. 4. A rock j-hook vane will be constructed along the right streambank (facing downstream) to promote pool development and maintenance thxoughout this section of channel. The structure will also help to reduce the overall shear currendy etoding the bank through this section. Upon completion of the structure, the upstream portion of the vane will be lined with geotextile fabric and backfilled with native material. Any distutbed streambanks will be graded, seeded and covered with erosion control matting. 5. Debris throughout the meanderbend will be repositioned to allow for natuxal channel maintenance. The repositioning of this material will be implemented in a manner that is consistent with typical habitat for aquatic wildlife, without compromising ovetall sediment transport. 6. The xemaining center bars downstream of the meanderbend will be removed and the material will be placed along the adjacent streambanks. The dimension of the channel will remain consistent with Regional Curve data. 7. Once construction activities have been completed, the contractor will seed all distutbed areas. Bare-xooted and live-staked vegetation will be installed according to the buffer guidelines presented with the grant. 5.0 DESIGN IMPLEMENTATION Implementation will follow the design sequence listed on the plan sheet. The installation of structures will proceed fxom upstream to downstream. As a result, shifts in the flows can be addressed with the placement of structutes downstteam. The actual locations of the structures may be adjusted, depending on site conditions. Implementation must take place prior to September 1, 2005 and is anticipated to take less than five total days. , aFj . ?. . ...'? ` . , , f ? ??yf•; .?f?i? .? _ - _ :; ??- P ?VV . ? ?'????y('??- •p?? ? :? ?e4 - ? 1;,? k'ii k.

I irnow that County experienced strpam damage as a result of the fall hurricanes. Our department would like to work closely with your county to insure that stream restoration projects receiving state and federal funds under the Emergency Watershed Protection (EWP) program move as smoothly as possible through the environmental review and permitting process. I have enclosed for your information a brief sumnlary of the types of permits and approvals that may be required for these projects. For projects that involve work directly affecting the streambed, the United States Army Corps of Engineers will be the primary environmental permitting agency. For those projects, our staff in the Division of Water Quality and the Division of Land Resources play a supporting role and issue related state approvals. I have asked our staff to meet with all of the western counties, either individually or in small groups, to talk about each county's proposed stream restoration projects and answer your questions about permit requirements. Our staff will ask the Corps of Engineers and Soil and Water Conservation staff to join in those meetings in an effort to put together a plan of action for reviewing and approving stream restoration projects as quickly as possible. You should receive a telephone call from DENR staff soon to talk about a date and time that would be convenient to meet and talk about your projects. I have also directed our staff to waive fees for state water quality certifications (under Section 401 of the Clean Water Act) and for approval of erosion and sedimentation ? February 25, 2005 Page 2 of 2 control plans for stream-clearing projects funded under EWP. Fees will be waived for all EWP permit s requested by Septernber 1, 2005. I hope these efforts will ease the burden on county governments already challenged by the demands of reconstruction and recovery. If we can help you in any other way, please do not hesitate to call. I have asked Assistant Secretary Robin Smith to be a- primary contact on these projects for DENR; you can reach Ms. Smith at (919) 715-4141. The enclosed information sheet also provides contact information for DENR staff in both the Asheville and Winston-Salem Regional Offices and for the Corps of Engineers office in Asheville.
