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 450 feet North Toe River 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. Mitchell County: Page 3 of G July 18, 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. North Toe River is classified C, Trout. As such, the following Administrative Codes . apply: 15A NCAC 0413.0125 and 15A NCAC 02B.0211 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, 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. 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. Mitchell County: Page 4 of G July 18, 2005 9. The channel must 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. 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 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. 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.As long-term stream stability is a concern with this type of work, it is strongly recommended that woody vegetation be established along stream banks where possible. Any riparian vegetation planting should be performed in accordance with the Guidelines for Riparian Buffer Restoration. (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 1St 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. Mitchell County: Page 5 of 6 July 18, 2005 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. 16. Diffuse Flow r 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 2B. .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.

Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: Land use in the vicinity of the proposed project site consists ofpriniarily agricultural and residential uses. Portions of the North Toe River were heavily impacted during Tropical Storms Frances and Ivan. In numerous locations, the stream is clogged with woody and non- native debris, reducing the hydraulic capacity of the channel. Additionally, one area of streambank erosion threatens the stability of adjacent properties and structures. 10. Describe the overall project in detail, including the type of equipment to be used: The ETVP project area known as DSR No. A12004-14 is addressed by this permit application. The project area consists of the North Toe River and its tributaries. The total estimated disturbed area for activities covered under this PCN is approximately 0.5 acres. Since this is less than the Erosion and Sediment Control Plan permitting threshold of 1 acre, a formal approval of the Erosion and Sediment Control Plan elements of this proposal is not needed. However, the total disturbed length of the buffer area for iVork Area 91 is more than 100 feet, therefore a formal request for a Trout waiver is being submitted. The North Toe River is classified as `Class C' and Trout' waters throughout the project area. The following activities are proposed in the project area: 1) One distinct area in need of stream bank stabilization has been identified, totaling approximately 4501inear feet. High hater flow has severely eroded stream banks in this area. In places, the riverbanks are over-steepened and very unstable, threatening structures and property. Repairs in these areas will involve the following: • Stabilize the channel in its post flood configuration using organic and rock structures. • Stabilize the river banks by: removing unstable vegetation; stabilizing the toe of the slope where necessary by placing large angular stone just above the water level, or by the use offiber logs; backfilling behind and above the stone with rocky debris removed from the floodplain or imported to the site; topping with planting media and planting native vegetation. 2) Removal of organic, mineral, and non-native material fi°om areas where the hydraulic capacity of the stream channel has been reduced based upon evaluation of existing cross- sections and regional curves. 3) Softening of rnifzor over-steepened banks and riparian planting. Work will include: stream bank stabilization in several areas described below. Equipment used to accomplish the above tasks includes: rubber tired skidders, 15 toll dinnp truck, hydraulic track mounted excavator with thumb, and chainsaws. The general location of the stream bank repair area is provided in Figures 1 & 2. Representative photos from these areas are included as Figures 3. Repairs for each of the areas are detailed in Figures 3A. Stemnbank Stabilization Streambank stabilization is needed on approximately 450 feet of banks within the project area. Stabilization is required at one distinct location shown in Figures 2. Repairs at this area will generally include stabilizing the bank in its current location. A key in trench will be excavated on the outside of the curve at the base of the existing slope as necessary. Large (three to four foot diameter) angular rock, large diameter logs (greater than 2 feet), and/or natural fiber logs will be used to stabilize the toe of the bank at high stress locations (e.g. the outside of bends). A second tier of material will be used, as needed. The area behind the material will be backfilled with rocky debris material excavated from the floodplain or imported material, and topsoil will be placed on the top of the reconstructed bank to aid in the establishment of vegetation. Where sufficient space is available a bankfull bench will be constructed in the fill area to increase hydraulic capacity and enhance future bank stability. The area will be seeded with grasses upon completion of heavy equipment work. With the landowner's permission, live stakes and bare root stock native trees and shrubs will be planted on top of the bank stabilization work. In areas where high stress on the toe is not expected (e.g. the inside of bends and straight sections with low banks), the use of large material is not necessary, and logs or natural fiber logs will be used to provide the necessary toe stabilization. Work will be performed front the riverbank to the extent possible. In some locations, work will occur in the dry above the normal water surface level. However, given the existing condition of the stream bank and channel at these locations, it is likely that the stabilization of the toe of the banks will occur in the wet. In such cases, sand bags, or the equivalent, will be used to deflect water flow away from the work area, as well as prevent water from accumulating in the work area. Standard erosion and sedimentation control measures, as subsequently described, will be utilized throughout the project. The work addressed in this application is intended to improve the post flood hydraulic capacity of the stream reaches discussed and stabilize severely eroded streambanks that are threatening structures. The proposed actions are not intended to enhance existing conditions or restore the stream reaches using natural channel design techniques. Such activities would require detailed engineering evaluation and design, which are beyond the intent of the EWP program. On May 2, 2005, in anticipation of upcoming work under the EWP Program, the Board of Commissioners of Mitchell Countypassed a resolution authorizing access to private land in order to conduct EWP repairs. For this reason, individual Access Agreements are not necessary for the workproposed in this PCN. A copy of the resolution is attached to this application. A summary of property owners is included as Table 1. At the site, work shall proceed from downstream to upstream to reduce sediment loading. All staging areas will be less than half an acre in size. Work will proceed as follows at each work area (as applicable): 1. Flag the lvork limits. 2. Mark live trees and shrubs to be protected. 3. Construct temporary construction entrancelexits where necessary. 4. Install sediment fence around staging areas. 5. At the end of each workday install erosion control matting on exposed soil using removable stakes. Erosion control mats will be constructed of coin fiber or a coir fiber mixture fabric for maximum erosion protection, vegetation establishment assistance, and for minimal impact on wildlife. The applicant is considering the use of pre-vegetated coir mats to improve erosion control measures and speed the re-vegetation process. 6. During construction, place large boulders, logs, or fiber rolls at the toe of repaired streambanks where necessary. 7. Fill and compact behind boulders, logs, or fiber rolls. Cover with topsoil, install erosion control mat, and seed. 8. Inspect and maintain repairs. A site-specific engineering design based on a specific storm event was not completed because the EIVP program is not intended to fiend stream restoration design or construction work. Rather, the EYVP program is designed to quickly stabilize eroding stream banks to prevent on- going erosion, sedimentation and possible loss ofproperty or life. Because natural channel design methods are beyond the scope of the EiVP program, published literature values were consulted in order to specify the bank stabilization and erosion control materials and methods described in this document. For example, we have specified that filter cloth will be placed behind large rock used for streambank stabilization or for in-stream structures to increase the stability of the repair measures and minimize sediment loading to the stream. If root-wads are used they will be installed so that at least 113 of the root is inundated during normal flows. Clean, large, angular rock, large woody material, and natural fiber erosion control mats will be used for streambank stabilization. Once site construction has ceased, the banks of the restored channel will be seeded with a native floodplain seed mix and the high stress areas will be lined with erosion control (EC) matting to ensure bank stability. Furtherniore, sod matting will be grubbed on-site and used (when available) to line the near bank regions of the constructed/stabilized channel to provide immediate stability. Live stakes and matting staples will be used to secure the EC fabric/sod- matting in these high stress areas. Broadcast seeding rates will be as specified from the local nursery, generally 15-20 lbs/acre depending on species. Native shrub and tree species will be planted throughout the project reach at a rate of 320 stenis/acre, securing near batik areas and providing fitture shadiiig to the chaniiel. Existing woody vegetation will be preserved to minimize project impacts. The following steps will be observed with respect to vegetation: 1. Exposed soil will be covered with erosion control matting at the end of every workday. Mats will be secured using removable stakes. 2. The project riparian zone and/or buffer areas will be re-vegetated with a combination of native trees, shrubs and herbs/grasses. All disturbed areas will be seeded with a temporary native grass mixture immediately following completion of the work in those areas. Tall fescue will not be used in riparian areas. 3. When possible sod will be taken from adjacent areas (with landowner permission) and placed on exposed soil to provide immediate stabilization within five days of ground disturbing activities. 4. If sod is not available on-site temporary seeding will occur on all bare soil within five days of ground disturbing activities to provide long-term erosion control. If sod is used, the bare area left after removal of sod will be planted. 5. Re-seeding will be conducted, as necessary, with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet, or other grain 6. Woody vegetation will be planted during the normal growing season assuming landowner permission. Removal of Organic and Rocky Debris The applicant recognizes that some woody debris in the riparian zone is a necessary component of habitat integrity and will strive to remove only non-native objects and those debris elements considered an immediate or impending threat to life and structures. Contractors performing debris removal tasks will be instructed to access debris on both sides of the river from the bank on which the debris is located. Contractors will be instructed specifically to keep heavy equipment out of the river channel. In some circumstances, it is likely that chainsaw operators or heavy equipment support personnel may need to get in the river to cut or help free debris jams being removed' In addition, large debris being pulled from the riverbank may result in some riverbank scour. The applicant will instruct contractors performing the work to refrain from cutting any live vegetation unless it is leaning toward the river at more than a 30-degree angle and the river is entrenched or the riverbank is unstable at that point. Debris removed will be hauled off site or chipped and disposed of in the flood plain. In cases where it is determined that large woody debris can be utilized in current or projected future bank stabilization work, such as in log vanes or as root wads, these articles may be stored on site out of the floodway upon landowner permission. All areas disturbed due to debris removal and equipment access will be reshaped and reseeded. Access to the channel will be perpendicular to the channel. Precaution will be taken to protect mast production and stream canopy trees. Dead trees that provide den habitat and are determined to pose no hazard to the channel shall be protected Rocky debris within the flood plain and channel that reduces the hydraulic capacity of the channel will be removed using an excavator. The removal of rocky debris will proceed from the stream channel back toward the streambank allowing the excavator to work on the debris pile. The reconfigured floodplain will be shaped in a manner intended to restore the hydraulic capacity of the stream system. Rocky debris removed from the floodplain will be used to stabilize the streambank, or will be hauled offsite. At sites where there is no eroded streambank in the immediate vicinity, the excavated material will be used to strengthen the natural berm of the streambank or will be hauled off site. In no case shall the deposited material be placed at an elevation higher than the existing streambanks. 11. Explain the purpose of the proposed work: The work being described is exigency work under the Emergency IYatershed Protection program to protect existing property and structures. Streambank stabilization will also prevent firrther erosion and sedimentation to the North Toe River resource. IV.

Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: Land use in the vicinity of the proposed project site consists of primarily agricultural and residential uses. Portions of the North Toe River were heavily impacted during Tropical Storms Frances and Ivan. In numerous locations, the stream is clogged with woody and non- native debris, reducing the hydraulic capacity of the channel. Additionally, one area of streambank erosion threatens the stability of adjacent properties and structures. 10. Describe the overall project in detail, including the type of equipment to be used: The ETYP project area known as DSR No. M2004-14 is addressed by this permit application. The project area consists of the North Toe River and its tributaries. The total estimated disturbed area for activities covered under this PCN is approximately 0.5 acres. Since this is less than the Erosion and Seduitent Control Plan permitting threshold of I acre, a formal approval of the Erosion and Sediment Control Plan elements of this proposal is not needed. However, the total disturbed length of the buffer area for Work Area 41 is more than 100 feet, therefore a formal request for a Trout waiver is being submitted. The North Toe River is classified as `Class C' and `Trout' waters throughout the project area. The following activities are proposed in the project area: 1) One distinct area in need ofstream bank stabilization has been identified, totaling approximately 4501inear feet. High water flow has severely eroded stream banks in this area. In places, the riverbanks are over-steepened and very unstable, threatening structures and property. Repairs in these areas will involve the following: • Stabilize the channel in its post- flood configuration using organic and rock structures. • Stabilize the river banks by: removing unstable vegetation; stabilizing the toe of the slope where necessary by placing large angular stone just above the water level, or by the use offiber logs; backfilling behind and above the stone with rocky debris removed from the floodplain or imported to the site; topping with planting media and planting native vegetation. 2) Removal of orgaiiic, »iiiieral, and non-native material front areas where the irydraulic capacity of the stream channel has been reduced based upon evaluation of existing cross- sections and regional curves. 3) Softeizing of miiior over-steepeied banks and riparian planting. Work will include: stream bank stabilization in several areas described below. Equipment used to accomplish the above tasks includes: rubber tired skidders, 15 ton dump truck, hydraulic track mounted excavator with thumb, and chainsaws. The general location of the stream bank repair area is provided in Figures I & 2. Representative photos from these areas are included as Figures 3. Repairs for each of the areas are detailed in Figures 3A. Sb emubank Stabilization: Streambank stabilization is needed on approximately 450 feet of banks within the project area. Stabilization is required at one distinct location shown in Figures 2. Repairs at this area will generally include stabilizing the bank in its current location. A key in trench will be excavated on the outside of the curve at the base of the existing slope as necessary. Large (three to four foot diameter) angular rock, large diameter logs (greater than 2 feet), and/or natural fiber logs will be used to stabilize the toe of the bank at high stress locations (e.g. the outside of bends). A second tier of material will be used, as needed. The area behind the material will be backfilled with rocky debris material excavated from the floodplain or imported material, and topsoil will be placed on the top of the reconstructed bank to aid in the establishment of vegetation. Where sufficient space is available a bankfull bench will be constructed in the fill area to increase hydraulic capacity and enhance future bank stability. The area will be seeded with grasses upon completion of heavy equipment work. With the landowner's permission, live stakes and bare root stock native trees and shrubs will be planted on top of the bank stabilization work. In areas where high stress on the toe is not expected (e.g. the inside of bends and straight sections with low banks), the use of large material is not necessary, and logs or natural fiber logs will be used to provide the necessary toe stabilization. Work will be performed from the riverbank to the extent possible. In some locations, work will occur in the dry above the normal water surface level. However, given the existing condition of the stream bank and channel at these locations, it is likely that the stabilization of the toe of the banks will occur in the wet. In such cases, sand bags, or the equivalent, will be used to deflect water flow away from the work area, as well as prevent water from accumulating in the work area. Standard erosion and sedimentation control measures, as subsequently described, will be utilized throughout the project. The work addressed in this application is intended to improve the post flood hydraulic capacity of the stream reaches discussed and stabilize severely eroded streambanks that are threatening structures. The proposed actions are not intended to enhance existing conditions or restore the stream reaches using natural channel design techniques. Such activities would require detailed engineering evaluation and design, which are beyond the intent of the EIVP program. On May 2, 2005, in anticipation of upcoming work under the EWP Program, the Board of Commissioners of Mitchell Countypassed a resolution authorizing access to private land in order to conduct EWP repairs. For this reason, individual Access Agreements are not necessary for the workproposed in this PCN. A copy of the resolution is attached to this application. A summary of property owners is included as Table 1. At the site, work shall proceed from downstream to upstream to reduce sediment loading. All staging areas will be less than half an acre in size. Work will proceed as follows at each work area (as applicable): 4 1. Flag the work limits. 2. Mark live trees and shrubs to be protected 3. Construct temporary construction entrancelexils where necessary. 4. Install sediment fence around staging areas. 5. At the end of each workday install erosion control matting on exposed soil using removable stakes. Erosion control mats will be constructed of coir fiber or a coir fiber mixture fabric for maximum erosion protection, vegetation establishment assistance, and for minimal impact on wildlife. The applicant is considering the use ofpre-vegetated coir mats to improve erosion control measures and speed the re-vegetation process. 6. During construction, place large boulders, logs, or fiber rolls at the toe of repaired streambanks where necessary. 7 Fill and compact behind boulders, logs, or fiber rolls. Cover with topsoil, install erosion control mat, and seed. 8. Inspect and maintain repairs. A site-specific engineering design based on a specific storm event was not completed because the ETVP program is not intended to fund stream restoration design or construction work. Rather, the ETVP program is designed to quickly stabilize eroding stream banks to prevent on- going erosion, sedimentation and possible loss ofproperty or life. Because natural channel design methods are beyond the scope of the ETVP program, published literature values were consulted in order to sped the bank stabilization and erosion control materials and methods described in this document. For example, we have specified that filter cloth will be placed behind large rock used for streambank stabilization or for in-stream structures to increase the stability of the repair measures and minimize sediment loading to the stream. If root-wads are used they will be installed so that at least 113 of the root is inundated during normal flows. Clean, large, angular rock, large woody material, and natural f ber erosion control mats will be used for streambank stabilization. Once site construction has ceased, the banks of the restored channel will be seeded with a native floodplain seed mix and the high stress areas will be lined with erosion control (EC) matting to ensure bank stability. Furthermnore, sod matting will be grubbed on-site and used (when available) to line the near bank regions of the constructed/stabilized channel to provide immediate stability. Live stakes and matting staples will be used to secure the ECfabriclsod- matting in these high stress areas. Broadcast seeding rates will be as specified from the local nursery, generally 15-201bs/acre depending on species. Native shrub and tree species will be planted throughout the project reach at a rate of 320 steams/acre, securing near bank areas and providing future shading to the charnel. Existing lvoody vegetation will be preserved to minimize project impacts. The following steps will be observed with respect to vegetation: 1. Exposed soil will be covered with erosion control matting at the end of every workday. Mats will be secured using removable stakes. 2. The project riparian zone andlor buffer areas will be re-vegetated with a combination of native trees, shrubs and herbs/grasses. All disturbed areas will be seeded with a temporary native grass mixture immediately following completion of the work in those areas. Tall fescue will not be used in riparian areas. 3. When possible sod will be taken from adjacent areas (with landowner permission) and placed on exposed soil to provide immediate stabilization within five days of ground disturbing activities. 4. If sod is not available on-site temporary seeding will occur on all bare soil within five days of ground disturbing activities to provide long-term erosion control. If sod is used, the bare area left after removal of sod will be planted. 5. Re-seeding will be conducted, as necessary, with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet, or other grain 6. Woody vegetation will be planted during the normal growing season assuming landowner permission. Removal of Organic and Rocky Debris The applicant recognizes that some woody debris in the riparian zone is a necessary component of habitat integrity and will strive to remove only non-native objects and those debris elements considered an immediate or impending threat to life and structures. Contractors performing debris removal tasks will be instructed to access debris on both sides of the river from the bank on which the debris is -located. Contractors will be instructed specifically to keep heavy equipment out of the river channel. In some circumstances, it is likely that chainsaw operators or heavy equipment support personnel may need to get in the river to cut or help free debris jams being removed. In addition, large debris being pulled from the riverbank may result in some riverbank scour. The applicant will instruct contractors performing the work to refrain from cutting any live vegetation unless it is leaning toward the river at more than a 30-degree angle and the river is entrenched or the riverbank is unstable at that point. Debris removed will be hauled off site or chipped and disposed of in the flood plain. In cases where it is determined that large woody debris can be utilized in current or projected future bank stabilization work, such as in log vanes or as root wads, these articles may be stored on site out of the floodway upon landowner permission. All areas disturbed due to debris removal and equipment access will be reshaped and reseeded. Access to the channel will be perpendicular to the channel. Precaution will be taken to protect mast production and stream canopy trees. Dead trees that provide den habitat and are determined to pose no hazard to the channel shall be protected. Rocky debris within the flood plain and channel that reduces the hydraulic capacity of the channel will be removed using an excavator. The removal of rocky debris will proceed from the stream channel back toward the streambank allowing the excavator to work on the debris pile. The reconfigured floodplain will be shaped in a manner intended to restore the hydraulic capacity of the stream system. Rocky debris removed from the floodplain will be used to stabilize the streambank, or will be hauled offsite. At sites where there is no eroded streambank in the immediate vicinity, the excavated material will be used to strengthen the natural berm of the streambank or will be hauled off site. In no case shall the deposited material be placed at an elevation higher than the existing streambanks. 11. Explain the purpose of the proposed work: The work being described is exigency work under the Emergency TYatershed Protection program to protect existing property and structures. Streanrbank stabilization ivill also prevent further erosion and sedimentation to the North Toe River resource. IV.

On behalf of Mitchell County, Altamont will provide contractors engaged in the implementation of this work both written and verbal instructions of all impact avoidance statements provided below. All heavy equipment will be kept out of the stream channel during streambank stabilization and stream relocation tivork except where absolutely necessary to install bank stabilization measures. Disturbance of channel bottom and banks and equipment access areas shall be held to the minimwn necessary to allow for bank stabilization and debris removal sufficient to restore the hydraulic capacity of the channel. Temporary grass cover shall be planted on all bare soil lvithin S days ofground disturbing activities. Provided landowners give permission, herbaceous and woody shrub and tree vegetation will also be installed on the riverbank upon completion of bank stabilization work. Mitchell County will provide a site manager to routinely inspect and supervise contractor work to help ensure impact avoidance instructions are being followed. 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 http•//h2o.enr.state.nc.us/ncwetlands/strmgide.litml. 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. N/A 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP).
