Division of Water Quality (DWQ) on November 21, 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 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. The authorization does not authorize the extensive slope toe stabilization presented in the application. The "toe of slope" is only the location where the stream bottom meets the bank slope and hardening in this area must be limited to immediately eroding areas. Also, the "hard" stabilization measures shall not extend above the mean water level as determined from the nearest USGS gauging station (this data must be provided to the DWQ Asheville Office prior to beginning work). (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 401 Wetlands Certification Unit - 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 ''" ?- ?E''•# 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786 /FAX 919-733-6893 / Internet http://h2o.enr.state.nc.us/ncwetlands An Equal Opportunity/Affirmative Action Employer - 50% Recycled/10% Post Consumer Paper Jackson County: Pale 2 of 6 November 29, 2005 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: 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 1000 feet Tuckase ee 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. Jackson County: Page 3 of 6 November 29, 2005 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. 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. 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, Jackson County: Page 4 of 6 November 29, 2005 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. 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 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 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 willow, tag alder, black willow, Jackson County: Pa.ge 5 of 6 November 29, 2005 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 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, 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. 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 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 attached.) 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. 17. 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. 18. 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. Jackson County: Page 6 of 6 November 29, 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. 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. This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act.

We replied in letters dated May 13, 2005; August 24, 2005; and August 30, 2005, agreeing with your conclusions on all but two of the DSR proposals--DSR-1 and DSR-23. We now have additional information regarding these two sites. On October 26, 2005, we visited site DSR 1 with Fish and Wildlife Associates, Inc., staff and observed•the stream-substrate.and the results ofdye testing.at tlie,s4eam-bank area., We received reports on,.the Morgan Property. (DSR 1) and the; Cook Property (DSR-23) on.November 4I... . . The following comments are provided in accordance with the Migratory Bird Treaty Act (16 U.S.C.. 703, et seq.);.section:7.of the Endangered Species Act,of.1973, as,amended (16 U.S.C. 1531-1543) (Act); and the Fish and Wildlife Coordination Act.(16.U,S.C: 661 et seq.). Emergency Watershed Protection. Flood damage to stream banks and channels occurred in the watersheds of several streams in western North Carolina from extreme flows during and following extensive rainfall associated with the two storms in September 2004.. Assistance to North Carolina counties is proposed under the EWP Program of the Natural. Resources Conservation Service (NRCS). According to 7 CFR, Part 624.2, "The objective of the EWP program is to assist in relieving imminent hazards to life and property from floods and the products of erosion created by natural disasters that cause'a sudden impairment of a watershed." We previously provided the following recommendations to minimize and avoid potential adverse impacts to fish and wildlife resources at these sites: DSR 1. In your letter of April 29, 2005, you proposed to reconstruct the stream bank and stabilize the stream to protect a 24-inch sewer line. Additional recommendations in the November 4, 2005, report proposed work only from the. stream bank, with no machinery in the water, and work during high flows from upstream generation. We found the October 26, 2005, dye test helpful for identification of.the location and habitats potentially affected.by.thc,proposed EWP :work at tlus site •: < DSR-;3.: In your. letter .of April, 29,e-20.05; you proposed to reconstruct tlie,strearri bank and stabilize he.streamao: protect :a; 24-inch sewer, line.. Additional recommendations in the November 4, 2005, report proposed work only from the stream bank, with no machinery in the water, and work during high flows from upstream generation. Endangered Species. According to the results of mussel surveys conducted at both sites on September 17, 2005, and October 5, 2005, Appalachian elktoes and wavy-rayed lampmussels occupy the river reach adjacent to the proposed EWP work. DSR-1 and DS-23 are adjacent to critical habitat of the reach of the Tuckasegee River that is designated critical habitat for, and is occupied by, the endangered Appalachian elktoe. According to the plans and the results of surveys performed by Fish and Wildlife Associates, Inc., the Appalachian elktoes that are in the area affected by the EWP activities have been marked. Construction/stabilization activities will be accomplished from the stream bank and will be scheduled during periods of higher flows.t We concur with the determination that the activities proposed at these sites will not likely adversely affect endangered or threatened species or their habitats. Therefore, we believe the requirements under section 7 of the Act are fulfilled. However, obligations under section 7 of the Act must be reconsidered if: (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered, (2) this action is subsequently modified in a manner that was not considered in this review, or (3) a new species is listed or critical habitat is determined that may be affected by the identified action. If we can be of assistance or if you have any questions, please do not hesitate to contact Mr. Mark A. Cantrell of our staff at 828/258-3939, Ext. 227.

River Basin: Little Tennessee (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://112o.enr.state.nc.us/admin/maps/.) Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The proposed site consists of light residential use. The stream and stream banks were heavily impacted during Tropical Storms Frances and Ivan. Extensive stream bank erosion threatens the stability of existing structures. 9. Describe the overall project in detail, including the type of equipment to be used: This project area includes approximately 1,000 linear feet of the Tuckasegee River. The project area is located at 35.349444N 83.229722W. Highwater flows have severely eroded the left bank. The erosion threatens an adjacent sewer line right-of-way. The erosion begins under a power line right-of-way and continues downstream approximately 1,000 linear feet along the left bank to approximately the area near a small island. Attachment 1 contains representative photos of the eroded area. Repairs in this reach of stream will involve the following: -Stabilize the channel in its post-flood configuration using organic and rock structures -Reseed and plant woody vegetation The techniques that will be utilized for the proposed repairs at the EWP site listed above are described below. Streambank Repair Excavation equipment will access streambank repair areas from the top of bank and will not track into the stream channel. Locally obtained rock material will be used to stabilize the stream bank. Large boulders will be placed along the toe of the slope as necessary to stabilize and protect the toe. Banks will be seeded with grasses and planted with native woody material. Work will be done during higher flows, as requested by US Fish & Wildlife Service. Site specific design components are included in Attachment 1 for the impacted channel sections requiring stabilization. Drainage areas of project areas are also included in those attachments. The drainage area is used to determine the design storm peak flow using USGS Rural Regression equations for the Blue Ridge-Piedmont. Design storm velocity and shear stress values were also calculated. This information, in conjunction with the field investigation analysis, DSR notations, and agency guidance and regulations, were used to develop an appropriate streambank stabilization design. Additional information on general design features, erosion control practices and debris removal practices is included in Attachment 2. Page 3 of 10 10. Explain the purpose of the proposed work: The work addressed in this application is intended to stabilize severely eroded streambanks that are threatening property and the sewer line right-of-way.

The repair work will include some or all of the following elements. • Str rnbank Stabilization • Re-vegetation • Channel Relocation to Pre-Flood • Debris Removal Location NOW THEREFORE, the Property Owner hereby grants Jackson County a revocable, non-transferable liceose from the date of execution of this instrument until October 31, 2006, for access across the above descnbed property and further, the parties hereto agree: 1. Property owner grants temporary permission to Jackson County and its contractors and agents to enter upon the above described. property. This permission is granted solely for the purpose of assessing and repairing the flood damage caused by Hurricanes Frances and Ivan. More specifically this project will begin on the riverbank at the Morgan and Beutel corner and proceW downriver as far as the engineers deem appropriate until reaching a large sycamore tree leaning out over the river. The parties agree that there was no flood damage on this tract beyond this point. The specific route of this ingress and egress is to be chosen by the property owner. 2. Property owner grants permission to Jackson County and its contractors and agents to conduct stream stabilization measures, which may include using rocks, wood, hydro-seeding, Lurdscapirrg with native shrubs, or mulching. The property owner reserves the right to reject the planting of a species not in keeping with the surrounding flora. 3. The parties hereby acknowledge that there is a horse pasture that runs under the power lines on the aforementioned property. Property Owner rents the horse pasture to a 08/02/2005 11:19 5867528 PAGE 03 tenant who pastures four horses on the propc Ay. It is understood and agreed by the parties hereto that Jackson County will maintain the integrity of said pasture and the safety of the horses. Further, Jackson County agrees to be responsible for any damage caused to the pasture or the horses as a result of its presence and repair work. 4. Jackson County agrees to comply with local, state and federal laws applicable to the work, and further agrees to exercise due care and caution in the performance of all work on the Property. 5. This Agreement constitutes the entire understanding between the parties. All prior agreements or understandings, whether oral or written, are superseded. This Agreement may be amended only by a written document duly executed by the parties. 6. Emergency Watershed Protection measures are intended to repair flood damage to the stream and to return affected areas to pre-flood conditions. Repair and/or improvements to structures are not part of this EWP project. Damaged bridges, driveways, and eroded fields are not addressed by EWP measures. Jackson County and its contractors will strive to minimize any negative impact to the property owner or his property. The parties agree that Jackson County will adequately and thoroughly protect and compensate the property owner for any loss incurred as a result of this project. 7. This agreement does not provide confirmation that the subject site is eligible for Emergency Funds, nor does it encumber funds for any repair work at this site. 8. Property owner agrees to leave intact constructed repairs, including vegetation, until October 31?, 2006. However, it should be noted that Duke Power routinely has a portion of the flood-damaged area sprayed with herbicide. If Duke Power continues this form of right of way management to the water's edge, it may kill the shrubs or other vegetation the engineers choose to have planted. 9. It is understood and agreed that plants and trees on the left hand side of the woodland path, when facing downriver, will not be disturbed. It should be noted that this area includes a large population of Oconee Bells, which are an endangered species. Further, it is understood and agreed that there will be a construction inspector on site during this project who will be made aware of the plant population so that he or she can direct construction and equipment to avoid the area. Further, said area will be marked off with flagging. It is also understood and agreed that some of the trees on the right hand side of the path road will be left unharmed including the best butternut, the best walnut, the best cherry and as many others as feasible. Further, that parties agree that at the conclusion of the construction, Jackson County will return the woodland path to its original state by removing any gravel and apply organic mulch. 10. Although the property owner did not nominate this property for Federal and State aid, he understands the possible benefits this project may offer Jackson. County in terms of protecting its sewer collection lime. Hence it is the County's responsibility to acquire adequate easements to the land parcel where the project will be located. It is not the 08/02/2005 11:19 5867528 intent of the landowner to grant a temporary easement to this land parcel. This is left to the County so that direct negotiations with adjacent property owners will insure their needs are addressed. PAGE 04 11. It is understood that tho engineers, CHM2HILL, must have this license agreement before they will fully develop a plan for this project. It is also understood and agreed that this plan will be shown to the Property Owner for final approval when it is completed. Upon examination of the final plan, the Property Owner shall have the option to revoke this license and cancel the project upon his property. Jackson County or Representative By.

CLEARING AND DEBRIS REMOVAL Debris removal crews shall remove only that material which has been clearly marked by a representative of Jackson County and/or CH2M HILL, INC (Representative) as indicated by flagging and/or orange/red spray paint. ONLY marked debris is to be removed. Representative cannot authorize additional work. Any work that will result in an increase in cost must be submitted to CH2M HILL for approval prior to starting such work. hi the event that the contractor uses on-site chipping, the chipper may follow the clean-up crew along the length of the project reach. The Contractor is responsible to properly dispose of chips. Proper disposal may include spreading on site or removing off-site. On-site disposal requires written approval by the property owner. Unless specifically requested to leave the chips in a pile by a property owner the chipper shall make reasonable efforts to spread the chips as chipping progresses. Chippers and other heavy equipment will be staged and used at least 30-feet from the top of the streambank or on existing paved or graveled areas prepared in accordance with standard details described in Figure 18 (Attachment 1). Repair of any property damage resulting from debris removal is the sole responsibility of the Contractor. All debris removal shall be within the included sites as identified in this solicitation and as directed by the Representative. For bid preparation purposes, the Representative has marked and identified debris to be removed. Removed debris shall be placed only in those areas as directed by the Representative. For Bid purposes, debris staging areas are assumed to be within 300 feet of top of bank. On-site burning is not allowed. Fallen trees, limbs and dislodged brush within the cross section of the existing or original channel up to and including the debris line of the subject storm shall be removed. Any foreign (man-made) debris washed in from upstream, shall be removed. Marked trees severely undercut by stream bank erosion and trees severely leaning over the channel whose near term fall is apparent shall be removed. In general, Contractor clearing will be limited to the cutting of severely damaged trees leaning across the channel, and other trees as needed to gain access for equipment to points of channel blockage. P:VacksonCountyNC\330332\Pcmiitting\Group 12_DSR23\Attachmcnt 2\Dcbris Removal SOP_final.doc Disturbance of the channel bottom and banks, and equipment access areas shall be held to the minimum necessary to allow the construction equipment to remove the debris and shall be consistent with all state and federal permits. All areas disturbed due to debris removal or equipment access shall be reshaped and reseeded in accordance with standard details described in Figures 7-18 (Attachment 1). Access to the channel will generally be perpendicular to the channel so cutting of trees is held to a minimum with precaution taken to protect mast producing and stream canopy trees. Un-marked dead trees that provide den habitat and are determined to pose no hazard to the channel shall be protected. As such, the contractor will only remove marked debris. The contractor will exercise care in the areas of existing crops to minimize damages. PROVIDED EOUIPMF.NT & FACILITIES The Contractor shall provide adequate sanitary facilities for equipment operators and work crews. Portable facilities shall be provided at the worksite and arrangements made for proper servicing. A portable facility will be provided within 1,000 feet of the equipment and/or work crews at all times. COMMUNICATIONS Each mechanized piece of equipment and each work crew shall be equipped with a two way, battery operated radio. Radios shall be FM, have a minimum range of 5 miles. Radios shall be maintained "on" and in the receive mode at all times while the operator is at the site. Batteries shall be recharged overnight or as needed. An extra set of fully charged batteries shall be maintained on board the equipment at all times. Radios shall be equipped with clip-on hand mikes or headsets. Radios shall be maintained in good operating condition and equipment operators shall be knowledgeable in the use and care of the radios. Each Contractor site supervisor shall also maintain a secondary communication system compatible with the Representative's system. Brush Removal Guidelines • Small diameter brush and limbs (less than four inches in diameter) that will not cause damage if remobilized by high water will be cut into short lengths (five feet long or less) and left in place. • All marked, dislodged or uprooted larger diameter brush will be removed from the channel or streambank and chipped in designated areas greater than 30-feet from the top of the bank. • Saplings and shrubs with an intact root system are not to be removed. P:UacksonCountyNC\330332\Pemiitting\Group 12_DSR23\Attachment 2\Dcbris Removal SOP_final.doc Tree Removal Guidelines • Trees will be chipped in designated areas greater than 30-feet from the top of the streambank. Chippers and/or tub grinders may be staged on-site with written consent from the property owner or at a central location approved by the County. • Larger diameter trees may be pulled to the chipper using a mechanized winch provided the process does not create excess disturbance to the streambank. • Marked trees whose near term fall is apparent should be cut at the marked location, which will be indicated by a painted ring around the trunk at least three- feet above the ground surface. The root system shall not be removed from the streambank. • As approved by the Representative, larger diameter trees that cannot be moved using hand equipment will be cut to manageable lengths and removed. • The sale of chips or firewood is not allowed. Foreign Debris and Trash Removal Guidelines • Foreign (manmade) debris and trash will be bagged in orange trash bags where possible. • Filled trash bags will be removed from the channel and transported directly offsite by the Contractor to the local landfill. • Large debris must be loaded into a dump truck or roll-off container and transported to the local landfill for disposal. • Tipping fees for disposal shall be paid by the Contractor. Stream bed and Bank Repair Guidelines • All temporary stream crossings shall be installed as described in Figures 15 -18 (Attachment 1). • All Stream embankments disturbed by Contractor activities, denuded, or left bare as a result of debris removal shall be regraded, planted, and erosion control fabric installed as described in Figures 6, 7, and 9 -12 (Attachment 1). • Temporary staging, chipping, and work access points shall be regraded and grassed using a native grass/herb mix as outlined in Figures 6, 7, and 16 -18 (Attachment 1). • Contractor shall install erosion control measures as outlined in Figures 10 -18. P:VacksonCountyNC\330332\Pcrmitting\Group 12_DSR23\Attachmcnt 2\Dcbris Removal SOP-final.doc SUPERINTENDENCE OF EOUIPMENT AND WORK CREWS Any contractor providing three (3) or more pieces of equipment or five (5) or more work crew or equipment operators shall provide a non-working crew superintendent in addition to the required laborers and operators. The contractor shall designate in writing the names of the crew superintendent and an alternate prior to award of the contract. The crew superintendent shall provide on-site supervision of work crews and equipment operators. The crew superintendent shall be responsible for the safety of work crews and for the location and servicing of portable sanitary facilities. He/she shall be equipped with a portable communication as specified above. The crew superintendent shall communicate with the Representative to assure that work crews and equipment are performing at a satisfactory level. The crew Superintendent shall coordinate with the Representative to schedule equipment and operators for each days work and as far in advance as possible. The superintendent shall be responsible for keeping up with the daily operating times of all work crews and equipment and shall maintain a log of daily equipment and work crew operations. He/she shall coordinate daily with the Representative to concur on actual footage of streambank cleared. WORK DIRECTION Contractors and equipment operators will not perform activities requested or instructed by landowners or others at the worksite, except as confirmed by the assigned Representative. ENVIRONMENTAL CONSIDERATIONS Earth moving equipment will cross and operate in the stream flow only when necessary and only when directed to do so by the Representative. Equipment shall be maintained to prevent fuel, oil and lubricant spills in the vicinity of the stream. Refueling, repairs and lubrication will be performed at safe distances from the stream and only at locations approved by the Representative. Should fuel leaks, oil leakages or hydraulic pipe rupture occur during construction, the operators will immediately remove the equipment to a "safe" area and proceed with repairs. The Representative will direct operators to remove equipment from the stream whenever a leak is observed or suspected. SAFETY Contractor shall be responsible for the safe execution of this work and conform to all applicable state and federal regulations. Additionally, at work sites, where equipment will be operating on public roads, flagmen shall be stationed to warn oncoming traffic of congestion, construction road signs shall be in place and a means of removing sediment, mud or rocks from roadways shall be established. Residue deposited on roadways may be removed by sweep machine, manual sweeping methods or pressurized water. The contractor will be responsible for the implementation of these measures. P:UacksonCountyNC\330332\Pcmlitting\Group 12_DSR23\Attachment 2\Debris Removal SOP_final.doc Chain saw operators will be expected to perform debris removal operations during periods of extreme weather conditions and in areas of deep and fast moving water. The contractor is responsible for providing the necessary equipment, clothing and other gear to insure that laborers can perform effectively and safely under these conditions. The Contractor shall determine if working conditions are hazardous and/or of sufficient extreme to prevent efficient and effective operation. When such conditions exist, the Contractor shall shut down work crews until conditions improve. EQUIPMENT Equipment selection to complete the work is the Contractor's responsibility.

On October 26, 2005, we visited site DSR 1 with Fish and Wildlife Associates, Inc., staff and observe.d•the stream-substrate .and the results, of dye testing.at thq,stream-bank area., We received reports on-the Morgan Property. (DSR 1) and the; Cook Property (DSR-23) on November. 2005. The following comments are provided in accordance with the Migratory Bird Treaty Act (16 U.S.C.. 703, et seq.);.section:7.ofthe.Endangered Species. Act,of.1973, as,amended (16 U.S.C. 1531-1543) (Act); and the.Fish and Wildlife Coordination Act.(16..U.S.C: 661 et seq.). Emergency Watershed Protection. Flood damage to stream banks and channels occurred in the watersheds of several streams in western North Carolina from extreme flows during and following extensive rainfall associated with the two storms in September 2004.. Assistance to North Carolina counties is proposed under the EWP Program of the Natural. Resources Conservation Service (MRCS). According to 7 CFR, Part 624.2, "The objective of the EWP program is to assist in relieving imminent hazards to life and property from floods and. the products of erosion created by natural disasters that cause 'a sudden impairment of a watershed." We previously provided the following recommendations to minimize and avoid potential adverse impacts to fish and wildlife resources at these sites: • DSR 1. In your letter of April 29, 2005, you proposed to reconstruct the stream bank and stabilize the stream to protect a 24-inch sewer line. Additional recommendations in the November 4, 2005, report proposed work only from the. stream bank, with no machinery in the water, and work during high flows from upstream generation. We found the October 26, 2005, dye test helpful for identification of the location and habitats potentially affected.by.the proposed EWP :work,at.t}iis site...: . •: DSR-23.. In your. lelter of;Apn129,?- 2005;,you proposed to reconstruct the streain bank and- stabilize: the. stream: to, protect, a..24-inch, sewer line.. Additionalrecommen ationsin the November 4, 2005, report proposed work only from the stream bank, with no machinery in the water, and work during high flows from upstream generation. Endangered Species. According to the results of mussel surveys conducted at both sites on September 17, 2005, and October 5, 2005, Appalachian elktoes and wavy-rayed lampmussels occupy the river reach adjacent to the proposed EWP work. DSR-1 and DS-23 are adjacent to critical habitat of the reach of the Tuckasegee River that is designated critical habitat for, and is occupied by, the endangered Appalachian elktoe. According to the plans and the results of surveys performed by Fish and Wildlife Associates, Inc., the Appalachian elktoes that are in the area affected by the EWP activities have been marked. Construction/stabilization activities will be accomplished from the stream bank and will be scheduled during periods of higher flows.t We concur with the determination that the activities proposed at these sites will not likely adversely affect endangered or threatened species or their habitats. Therefore, we believe the requirements under section 7 of the Act are fulfilled. However, obligations under section 7 of the Act must be reconsidered if (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered, (2) this action is subsequently modified in a manner that was not considered in this review, or (3) a new species is listed or critical habitat is determined that may be affected by the identified action. If we can be of assistance or if you have any questions, please do not hesitate to contact Mr. Mark A. Cantrell of our staff at 828/258-3939, Ext. 227.

Project Information Attach a vicinity map clearly showing the location of the property with respect to local landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property boundaries and development plans in relation to surrounding properties. Both the vicinity map and site plan must include a scale and north arrow. The specific footprints of all buildings, impervious surfaces, or other facilities must be included. If possible, the maps and plans should include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion, so long as the property is clearly defined. For administrative and distribution purposes, the USACE requires information to be submitted on sheets no larger than 11 by 17-inch format; however, DWQ may accept paperwork of any size. DWQ prefers full-size construction drawings rather than a sequential sheet version of the full-size plans. If full-size plans are reduced to a small scale such that the final version is illegible, the applicant will be informed that the project has been placed on hold until decipherable maps are provided. 1. Name of project: Jackson County, EWP 2005-1 2. T.I.P. Project Number or State Project Number (NCDOT Only): NA 3. Property Identification Number (Tax PIN): 7630-88-8559 4. Location County: Jackson Nearest Town: Webster Subdivision name (include phase/lot number): NA Directions to site (include road numbers, landmarks, etc.): Take US Highway 23 to the City of Sylva. Exit the highway at the City of Sylva onto Grindstaff Cove Rd. The property is located off of Grindstaff Cove Rd. The property is on a TWSA (Tuckaseigee Water and Sewer Authority) right-of-way across land owned by Ralph S. Morgan. The mailing address for the TWSA is 401 Grindstaff Cove Road, Sylva, NC 28779. See Attachment 1 for site vicinity and parcel locations. 5. Site coordinates, if available (UTM or Lat/Long): 35.349444N 83.229722W (Note - If project is linear, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) 6. Property size (acres): not available 7. Nearest body of water (stream/river/sound/ocean/lake): Tuckasegee River Page 2 of 10 8. River Basin: Little Tennessee (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://l12o.enr.state.nc.tis/idmin/maps/.) Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The proposed site consists of light residential use. The stream and stream banks were heavily impacted during Tropical Storms Frances and Ivan. Extensive stream bank erosion threatens the stability of existing structures. 9. Describe the overall project in detail, including the type of equipment to be used: This project area includes approximately 1,000 linear feet of the Tuckasegee River. The project area is located at 35.349444N 83.229722W. Highwater flows have severely eroded the left bank. The erosion threatens an adjacent sewer line right-of-way. The erosion begins under a power line right-of-way and continues downstream approximately 1,000 linear feet along the left bank to approximately the area near a small island. Attachment 1 contains representative photos of the eroded area. Repairs in this reach of stream will involve the following: -Stabilize the channel in its post-flood configuration using organic and rock structures -Reseed and plant woody vegetation The techniques that Nvill be utilized for the proposed repairs at the EWP site listed above are described below. Streambank Repair Excavation equipment will access streambank repair areas from the top of bank and will not track into the stream channel. Locally obtained rock material will be used to stabilize the stream bank. Large boulders will be placed along the toe of the slope as necessary to stabilize and protect the toe. Banks will be seeded with grasses and planted with native woody material. Work will be done during higher flows, as requested by US Fish & Wildlife Service. Site specific design components are included in Attachment 1 for the impacted channel sections requiring stabilization. Drainage areas of project areas are also included in those attachments. The drainage area is used to determine the design storm peak flow using USGS Rural Regression equations for the Blue Ridge-Piedmont. Design storm velocity and shear stress values were also calculated. This information, in conjunction with the field investigation analysis, DSR notations, and agency guidance and regulations, were used to develop an appropriate streambank stabilization design. Additional information on general design features, erosion control practices and debris removal practices is included in Attachment 2. Pagc 3 of 10 10. Explain the purpose of the proposed work: The work addressed in this application is intended to stabilize severely eroded streambanks that are threatening property and the sewer line right-of-way. The proposed actions are not intended to enhance existing conditions or restore 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. IV.

Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ? uplands ? stream ? wetlands Describe the method of construction (e.g., datn/embankinent, excavation, installation of draw-down valve or spillway, etc.): NA Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stornwater requirement, etc.): NA Size of watershed draining to pond: NA Expected pond surface area: NA VII. Impact Justification (Avoidance and rUinimization) 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. Equipment will be kept out of the stream channel and will not cross the stream channel, and no excavation will be below the existing channel bed. When at all possible stream material will be moved from dry areas to banks, minimizing the movement of wet (or below water line) stream material. The channel cross-sectional area will not be altered. Temporary and/or permanent herbaceous vegetation shall be planted on all bare soil within 15 days of ground disturbing activities. Rocky material shall not be used for bank stabilization above the normal high water mark. Large rocky material will be brought in to stabilize the toe of impacted streambanks where necessary. 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, Page 6 of 10 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://li2o.enr.state.ne.us/ncwetIands/strm!zide.litnl1. 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).

MORGAN III of P.O. Box 146, Webster, North ?ddolina 28788, Licensor (hereinafter "Property Owner"), and JACKSON COUNTY, Licensee; WHEREAS, Ralph S. Morgan is the owner of property located in Webster Township along the Tuckasegee River more particularly described as Tract 11, in deed y; and recorded in Deed Book 523, Page 220, Jackson County Registr WHEREAS, Jackson County is requesting access across said property for the purposes of assessing and repairing damage to the streambank, stream channel, and floodplain that was caused by hurricanes Frances and Ivan. The repair efforts are being funded by the United States Natural Resource Conservation Service through the emergency watershed protection (EWP) program. The repair work will include some or all of the following elements: • Sh=mbank Stabilization • Re-vegetation • Channel Relocation to Pre-Flood • Debris Removal Location NOW THEREFORE, the Property Owner hereby grants Jackson County a revocable, non-transferable license from the date of execution of this instrument until October 31, 2006, for access across the above described property and further, the parties hereto agree: 1. Property owner grants temporary permission to Jackson County and its contractors and agents to enter upon the above described property. This permission is granted solely for the purpose of assessing and repairing the flood damage caused by Hurricanes Frances and Ivan. More specifically this project will begin on the riverbank at the Morgan and Beutel corner and proceed downriver as far as the engineers deem appropriate until reaching a large sycamore tree leaning out over the river. The parties agree that there was no flood damage on this tract beyond this point. The specific route of this ingress and cgress is to be chosen by the property owner. 2. Property owner grants permission to Jackson County and its contractors and agents to conduct stream stabilization measures, which may include using rocks, wood, hydro-seeding, landscaping with native shrubs, or mulching. The property owner reserves the right to reject the planting of a species not in keeping with the surrounding flora. 3. The parties hereby acknowledge that there is a horse pasture that runs under the power lines on the aforementioned property. Property Owner rents the horse pasture to a 08/©2/2©©5 11:19 5867528 PAGE ©3 tenant who pastures four horses on the property. It is understood and agreed by the parties hereto that Jackson County will maintain the integrity of said pasture and the safety of the horses. Further, Jackson County agrees to be responsible for any damage caused to the pasture or the horses as a result of its presence and repair work. 4, Jackson County agrees to comply with local, state and federal laws applicable to the work, and further agrees to exercise due care and caution in the performance of all work on the Property. 5. This Agreement constitutes the entira understanding between the parties. All prior agreements or understandings, whether oral or written, arc superseded. This Agreement may be amended only by a written document duly executed by the parties. 6. Emergency Watershed Protection measures are intended to repair flood damage to the stream and to return affected areas to pre-flood conditions. Repair and/or improvements to structures are not part of this EWP project. Damaged bridges, driveways, and eroded fields are not addressed by EWP measures. Jackson County and its contractors will strive to minimize any negative impact to the property owner or his property. The parties agree that Jackson County will adequately and thoroughly protect and compensate the property owner for any loss incurred as a result of this project. 7. This agreement does not provide confirmation that the subject site is eligible for Emergency Funds, nor does it encumber funds for any repair work at this site. 8. Property owner agrees to leave intact constructed repairs, including vegetation, until October 31?, 2046. However, it should be noted that Duke Power routinely has a portion of the flood-damaged area sprayed with herbicide. If Duke Power continues this form of right of way management to the water's edge, it may kill the shrubs or other vegetation the engineers choose to have planted. 9. It is understood and agreed that plants and trees on the left hand side of the woodland path, when facing downriver, will not be disturbed. It should be noted that this area includes a large population of Oconee Bells, which are an endangered species. Further, it is understood and agreed that there will be a construction inspector on site during this project who will be made aware of the plant population so that he or she can direct construction and equipment to avoid the area Further, said area will be marked off with flagging. It is also understood and agreed that some of the trees on the right hand side of the path road will be left unharmed including the best butternut, the best walnut, the best cherry and as many others as feasible. Further, that parties agree that at the conclusion of the construction, Jackson County will return the woodland path to its original state by removing any gravel and apply organic mulch. 10. Although the property owner did not nominate this property for Federal and State aid, he understands the possible benefits this projeci may offer Jackson County in terms of protecting its sewer collection line. Hence it is the County's responsibility to acquire adequate easements to the land parcel where the project will be located. It is not the 08/02/2005 11:19 5867528 intent of the landowner to grant a temporary easement to this land parcel. This is left to the county so that direct negotiations with adjacent property owners will insure their needs are addressed. PAGE 04 11. It is understood that the cn9ineer3, CHM2HIL1, must have this license agreement before they will fully develop a plan for this project. It is also understood and agreed that this plan will be shown to the Property Owner for final approval when it is completed. Upon examination of the final plan, the Property Owner shall have the option to revoke this license and cancel the project upon his property. reckson County or RepresentAtive By.

CLEARING AND DEBRIS REMOVAL Debris removal crews shall remove only that material which has been clearly marked by a representative of Jackson County and/or CH2M HILL, INC (Representative) as indicated by flagging and/or orange/red spray paint. ONLY marked debris is to be removed. Representative cannot authorize additional work. Any work that will result in an increase in cost must be submitted to CH2M HILL for approval prior to starting such work. In the event that the contractor uses on-site chipping, the chipper may follow the clean-up crew along the length of the project reach. The Contractor is responsible to properly dispose of chips. Proper disposal may include spreading on site or removing off-site. On-site disposal requires written approval by the property owner. Unless specifically requested to leave the chips in a pile by a property owner the chipper shall make reasonable efforts to spread the chips as chipping progresses. Chippers and other heavy equipment will be staged and used at least 30-feet from the top of the streambank or on existing paved or graveled areas prepared in accordance with standard details described in Figure 18 (Attachment 1). Repair of any property damage resulting from debris removal is the sole responsibility of the Contractor. All debris removal shall be within the included sites as identified in this solicitation and as directed by the Representative. For bid preparation purposes, the Representative has marked and identified debris to be removed. Removed debris shall be placed only in those areas as directed by the Representative. For Bid purposes, debris staging areas are assumed to be within 300 feet of top of bank. On-site burning is not allowed. Fallen trees, limbs and dislodged brush within the cross section of the existing or original channel up to and including the debris line of the subject storm shall be removed. Any foreign (man-made) debris washed in from upstream, shall be removed. Marked trees severely undercut by stream bank erosion and trees severely leaning over the channel whose near term fall is apparent shall be removed. In general, Contractor clearing will be limited to the cutting of severely damaged trees leaning across the channel, and other trees as needed to gain access for equipment to points of channel blockage. P:VacksonCountyNC\330332\Pcmiitting\Group 12_DSR23\Attachmcnt 2\Dcbris Rcmoval SOP_final.doc Disturbance of the channel bottom and banks, and equipment access areas shall be held to the minimutn necessary to allow the construction equipment to remove the debris and shall be consistent with all state and federal permits. All areas disturbed due to debris removal or equipment access shall be reshaped and reseeded in accordance with standard details described in Figures 7-18 (Attachment 1). Access to the channel will generally be perpendicular to the channel so cutting of trees is held to a minimum with precaution taken to protect mast producing and stream canopy trees. Un-marked dead trees that provide den habitat and are determined to pose no hazard to the channel shall be protected. As such, the contractor will only remove marked debris. The contractor will exercise care in the areas of existing crops to minimize damages. PROVIDED EOUIPMENT & FACILITIES The Contractor shall provide adequate sanitary facilities for equipment operators and work crews. Portable facilities shall be provided at the worksite and arrangements made for proper servicing. A portable facility will be provided within 1,000 feet of the equipment and/or work crews at all times. COMMUNICATIONS Each mechanized piece of equipment and each work crew shall be equipped with a two way, battery operated radio. Radios shall be FM, have a minimum range of 5 miles. Radios shall be maintained "on" and in the receive mode at all times while the operator is at the site. Batteries shall be recharged overnight or as needed. An extra set of fully charged batteries shall be maintained on board the equipment at all times. Radios shall be equipped with clip-on hand mikes or headsets. Radios shall be maintained in good operating condition and equipment operators shall be knowledgeable in the use and care of the radios. Each Contractor site supervisor shall also maintain a secondary communication system compatible with the Representative's system. Brush Removal Guidelines • Small diameter brush and limbs (less than four inches in diameter) that will not cause damage if remobilized by high water will be cut into short lengths (five feet long or less) and left in place. • All marked, dislodged or uprooted larger diameter brush will be removed from the channel or streambank and chipped in designated areas greater than 30-feet from the top of the bank. • Saplings and shrubs with an intact root system are not to be removed. P:UacksonCountyNC\330332\Permitting\Group 12_DSR23\Attachment 2\Debris Removal SOP_final.doc Tree Removal Guidelines • Trees will be chipped in designated areas greater than 30-feet from the top of the streambank. Chippers and/or tub grinders may be staged on-site with written consent from the property owner or at a central location approved by the County. • Larger diameter trees may be pulled to the chipper using a mechanized winch provided the process does not create excess disturbance to the streambank. • Marked trees whose near term fall is apparent should be cut at the marked location, which will be indicated by a painted ring around the trunk at least three- feet above the ground surface. The root system shall not be removed from the streambank. • As approved by the Representative, larger diameter trees that cannot be moved using hand equipment will be cut to manageable lengths and removed. • The sale of chips or firewood is not allowed. Foreign Debris and Trash Removal Guidelines • Foreign (manmade) debris and trash will be bagged in orange trash bags where possible. • Filled trash bags will be removed from the channel and transported directly offsite by the Contractor to the local landfill. • Large debris must be loaded into a dump truck or roll-off container and transported to the local landfill for disposal. • Tipping fees for disposal shall be paid by the Contractor. Stream bed and Bank Revair Guidelines • All temporary stream crossings shall be installed as described in Figures 15 -18 (Attachment 1). • All Stream embankments disturbed by Contractor activities, denuded, or left bare as a result of debris removal shall be regraded, planted, and erosion control fabric installed as described in Figures 6, 7, and 9 -12 (Attachment 1). • Temporary staging, chipping, and work access points shall be regraded and grassed using a native grass/herb mix as outlined in Figures 6, 7, and 16 -18 (Attachment 1). • Contractor shall install erosion control measures as outlined in Figures 10 -18. P:UacksonCountyNC\330332\Permitting\Group 12_DSR23\Attachment 2\Debris Removal SOP_final.doc SUPERINTENDENCE OF EOUIPMENT AND WORK CREWS Any contractor providing three (3) or more pieces of equipment or five (5) or more work crew or equipment operators shall provide a non-working crew superintendent in addition to the required laborers and operators. The contractor shall designate in writing the names of the crew superintendent and an alternate prior to award of the contract. The crew superintendent shall provide on-site supervision of work crews and equipment operators. The crew superintendent shall be responsible for the safety of work crews and for the location and servicing of portable sanitary facilities. He/she shall be equipped with a portable communication as specified above. The crew superintendent shall communicate with the Representative to assure that work crews and equipment are performing at a satisfactory level. The crew Superintendent shall coordinate with the Representative to schedule equipment and operators for each days work and as far in advance as possible. The superintendent shall be responsible for keeping up with the daily operating times of all work crews and equipment and shall maintain a log of daily equipment and work crew operations. He/she shall coordinate daily with the Representative to concur on actual footage of streambank cleared. WORK DIRECTION Contractors and equipment operators will not perform activities requested or instructed by landowners or others at the worksite, except as confirmed by the assigned Representative. ENVIRONMENTAL CONSIDERATIONS Earth moving equipment will cross and operate in the stream flow only when necessary and only when directed to do so by the Representative. Equipment shall be maintained to prevent fuel, oil and lubricant spills in the vicinity of the stream. Refueling, repairs and lubrication will be performed at safe distances from the stream and only at locations approved by the Representative. Should fuel leaks, oil leakages or hydraulic pipe rupture occur during construction, the operators will immediately remove the equipment to a "safe" area and proceed with repairs. The Representative will direct operators to remove equipment from the stream whenever a leak is observed or suspected. SAFETY Contractor shall be responsible for the safe execution of this work and conform to all applicable state and federal regulations. Additionally, at work sites, where equipment will be operating on public roads, flagmen shall be stationed to warn oncoming traffic of congestion, construction road signs shall be in place and a means of removing sediment, mud or rocks from roadways shall be established. Residue deposited on roadways may be removed by sweep machine, manual sweeping methods or pressurized water. The contractor will be responsible for the implementation of these treasures. P:VacksonCountyNC\330332\Pcrmitting\Group 12_DSR23\Attachmcnt 2\Dcbris Rcmoval SOP_final.doc Chain saw operators will be expected to perform debris removal operations during periods of extrerne weather conditions and in areas of deep and fast moving water. The contractor is responsible for providing the necessary equipment, clothing and other gear to insure that laborers can perform effectively and safely under these conditions. The Contractor shall determine if working conditions are hazardous and/or of sufficient extreme to prevent efficient and effective operation. When such conditions exist, the Contractor shall shut down work crews until conditions improve. EQUIPMENT Equipment selection to complete the work is the Contractor's responsibility.
