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 Plan Location or Reference Approved Units Stream Approximately Panthertown Creek 40 linear feet 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. Panthertown (Sassafras) Trail Bridge Page 3 of 6 April 18, 2006 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 should be avoided during the October 15 to April 15 trout spawning period to avoid adverse effects of sediment on eggs and larvae. 7. Sediment and erosion control measures must be implemented prior,to construction and maintained on the sites to minimize sediment in downstream areas. Seeding for a temporary cover of wheat, millet, or similar annual grain or permanent herbaceous cover should occur on all bare soil within five (5) days of ground disturbing activities to provide long-term erosion control. The projects should be accomplished in stages instead of leaving large tracts exposed to further storm events. Erosion control matting should be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas. Matting should be secured in place with staples, stakes, or, wherever possible, live stakes of native trees. Straw mulch and tall fescue should not be used in riparian areas. In addition, because of an anticipated difficulty in establishing ground cover during the winter, reseeding should be conducted, as necessary, in the spring-time with a native annual and perennial seed mix with a temporary nursery crop of wheat, millet or other grain. 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. Should large, angular rock, large woody material, or other natural stream design materials and techniques not be sufficient for long term stability of the stream and adjacent roadway, and concrete be incorporated into the design, measures which would prevent surface waters from coming into contact with live concrete. Panthcrtown (Sassafras) Trail Bridge Page 4 of 6 April 18, 2006 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. No backfilling of stream bed materials is allowed under this authorization. 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. Sandbags or other clean diversion structures should be used 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. Exposure of equipment to surface waters must be minimized to the maximum extent possible. 13. Disturbed stream banks and a 30-foot vegetated zone (as required under the Water Supply regulations), or the widest width that is practical under the site conditions, must 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, 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. Replanting of vegetation within disturbed areas located within 30 feet of the streambank associated with any land disturbing activity, repair, replacement and/or maintenance must be done in a manner consistant with the Guidelines for Riparian Buffer Restoration immediately following construction. (Please see attached.) 14. If pasture along the stream is to be used for grazing, a fence must be constructed outside of the riparian zone and the stream to prevent livestock from entering these areas. Panthertown (Sassafras) Trail Bridge Page 5 of 6 April 18, 2006 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. Turbidity Standard The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 213. .0200. Appropriate sediment and erosion control practices must be used to meet this standard. 17. 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. 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.

Name of project: Greenland Creek Trail Bridge Construction #451 - 0.3 (Spans Panthertown Creek) 2. T.I.P. Project Number or State Project Number (NCDOT Only): N/A 3. Property Identification Number (Tax PIN): N/A 4. Location County: Jackson Nearest Town: Lake Toxaway, NC Subdivision name (include phase/lot number): N/A Directions to site (include road numbers/names, landmarks, etc.): From Lake Toxaway, continue northwesterly on the "Cold Mountain Road " for 5.7 miles. At this point follow the Forest Services to the trailhead parking. The trail bridge is at milepost 0.3, past the closed road gate. 5. Site coordinates (For linear projects, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) Trail Bridge Decimal Degrees (6 digits minimum): 35.1750 ON 83.0119 °W 6. Property size (acres): Highlands Ranger District: 105,000 Acres 7. Name of nearest receiving body of water: Panthertown Creek 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://h2o.enr.state.nc.us/admin/maps/.) Page 2 of 10 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The project site for this trail bridge construction is Greenland Creek. Trail hiking, biking (mountain bikes), and sight seeing are major recreational activities throughout this tract. The trail bridge replaces an old, rotting road bridge. The trail system that serves this area consists of old roads that were put in place by the previous land owner(s). The Panthertown area was transferred ownership to the National Forest System on this large tract in the early 1990's. The forested area at this site is mixed conifer and hardwoods. The soils are sub soils of clayey cobble rock soils are overlaid with sandy silts at the bridge crossing. The.old bridge will be removed. There are no abutments for the old bridge as it sits atop the soils on both sides of the stream. The new structure will be adequate for horse traffic. 10. Overall project description in detail including the type of equipment to be used: This project consists of replacement of the existing bridge with a glued-laminated girder structure with a span of 40 feet. The abutments will consist of geocel foundations supporting structural concrete grade beams. A small excavator will most likely be used to remove the existing bridge, excavate for the geocel, place the riprap and set the glued- laminated girders. No in-stream work is anticipated except for setting the first course of riprap. The approaches will be surfaced with a four inch depth of aggregate. The two grade beams will be constructed off site and transported to the bridge site. Erosion and sedimentation control will be maintained throughout this project primarily through proper water management, construction sequencing, proper staging and stockpiling material, and maintenance at all times, of suitable channel capacity for expected flow events. No equipment, fuels, lubricants, or other potential sources of water pollution will be stored in areas that could be flooded during this project. Work within the wetted perimeter of the stream will not be allowed from October 15ti' - April 15ti'- 11'. Purpose of the proposed work: The replacement of the existing bridge is necessary to replace the existing, rotting structure. The old bridge will not support the 85 pounds per square foot required. The new bridge will provide access of trail maintenance equipment and at times, as in previous years, provide for the efficient retrieval of the occasional injured hiker. The new span will have the bottom of its girders set above the high water observed in the flooding of September 2004. Placement of the designed riprap will prevent future erosion of the abutments.

Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, must be listed, and must be labeled and clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) should be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: 2. Individually list wetland impacts. Types of impacts include, but are not limited to mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams, separately list impacts due to both structure and flooding.

Isolated Waters Do any isolated waters exist on the property? ? Yes ® No Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. 7. Pond Creation N/A If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. 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., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: Size of watershed draining to pond: Expected pond surface area: VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact Page 6 of 10 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. (See III., 10, above.) 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 January 15, 2002, 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 NCEEP concurrence shall be placed on hold as incomplete.

DECISION MEMO Trail Repairs and Relocations for Panthertown Valley.Trails Highlands Ranger District Nantahala National Forest Jackson County, North Carolina The Panthertown Valley trail system is a network of high-use trails located approximately six miles northwest of Lake Toxaway, near Cashiers, NC. Portions of thpse trails and several trail bridges were damaged by heavy rains received during tropical storms which passed through North Carolina during September 8, 17 and 24, 2004. This damage occurred more often on poorly located trail sections, such as, fall-line trails, poorly located user-created trails, and braided trails. Eroding tread surfaces are a source of sediment delivery into nearby creeks and user safety is compromised due to poor tread conditions and very steep trail grades. The purpose of this project is to relocate sections of trails and replace bridges that are deemed unsafe and damaged by the heavy rains to reduce future erosion and sediment delivery into local streams. A map of the proposed trail relocations is located in the project file. DECISION I have decided to implement the following actions needed to repair, realign and relocate several sections of the Panthertown Valley trails. All undesirable or unneeded trail sections and user- created non-system trails will be obliterated using logs, tree limbs, brush, live plants, soil and/or leaf litter to hide the trail and block access to it. Check dams will be installed, as needed, in gullied areas of the obliterated trails to decrease erosion. A. Panthertown Creek Trail 450 - Realign approximately 1800 feet of trail to create a safe and sustainable grade, correct drainage problems, and to move trail from boggy areas. B. Greenland Trail 451 - Obliterate approximately 350 feet of user-created fall-line trail which descends steeply downhill. Realign the trail as needed to create a safe and sustainable grade. C. Hogback Mountain Trail 453 -Construct two low-water crossings by adding rock to the creek bed which will allow maintenance vehicles to pass through the stream with little disturbance. Relocate a combined length of approximately 1,300 feet of trail in two unconnected locations. These relocations are needed to create a safe and sustainable grade and to move the trail out of gullied areas. D. Little Green Mountain Trail 485 - Relocate approximately 100 feet of trail around boggy areas. Use timber from puncheons destroyed during high water flows to construct a retaining wall approximately 40 feet long. The retaining wall will be located on a steep, eroding section of the trail past the trail junction to Schoolhouse Falls. E. Little Green Valley Trail 484 - Relocate approximately 120 feet of trail in two locations to move it out of old road cut banks and to correct drainage problems (add dips, water bars, and lead-outs). F. Greenland/Devils Elbow Trail 486 - Between Trails 474A and 451. This section of trail will be removed from the trail system by obliterating 300 feet of this trail at each end. These 300 foot sections may also be used for borrow material. G. Install three trail bridges - Greenland Creek Trail Bridges 451-0.3 and 451-0.0, and Pa nth ertown-Sassafra s Gap 448-0.1. H. Schoolhouse Falls Trail 452 - Relocate trail around boggy area with a boardwalk to be removed. This trail is a short section off of Little Green Mountain Trail 485 that provides access to Schoolhouse Falls. Since this analysis began the Forest Service has renamed this section of trail. It is now part of the Little Green Mountain Trail 485.

Site coordinates (For linear, projects, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) Trail Bridge Decimal Degrees (6 digits minimum): 35.1750 ON 83.0119 °W 6. Property size (acres): Highlands Ranger District: 105,000 Acres 7. Name of nearest receiving body of water: Panthertown Creek 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://h2o.enr.state.ne.us/admin/maps/.) Page 2 of 10 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The project site for this trail bridge construction is Greenland Creek. Trail hiking, biking (mountain bikes), and sight seeing are major recreational activities throughout this tract. The trail bridge replaces an old, rotting road bridge. The trail system that serves this area consists of old roads that were put in place by the previous land owner(s). The Panthertown area was transferred ownership to the National Forest System on this large tract in the early 1990's. The forested area at this site is mixed conifer and hardwoods. The soils are sub soils of clayey cobble rock soils are overlaid with sandy silts at the bridge crossing. The.old bridge will be removed. There are no abutments for the old bridge as it sits atop the soils on both sides of the stream. The new structure will be adequate for horse traffic. 10. Overall project description in detail including the type of equipment to be used: This project consists of replacement of the existing bridge with a glued-laminated girder structure with a span of 40 feet. The abutments will consist of geocel foundations supporting structural concrete grade beams. A small excavator will most likely be used to remove the existing bridge, excavate for the geocel, place the riprap and set the glued- laminated girders. No in-stream work is anticipated except for setting the first course of riprap. The approaches will be surfaced with a four inch depth of aggregate. The two grade beams will be constructed off site and transported to the bridge site. Erosion and sedimentation control will be maintained throughout this project primarily through proper water management, construction sequencing, proper staging and stockpiling material, and maintenance at all times, of suitable channel capacity for expected flow events. No equipment, fuels, lubricants, or other potential sources of water pollution will be stored in areas that could be flooded during this project. Work within the wetted perimeter of the stream will not be allowed from October 15t' - April 15th. 11. Purpose of the proposed work: The replacement of the existing bridge is necessary to replace the existing, rotting structure. The old bridge will not support the 85 pounds per square foot required. The new bridge will provide access of trail maintenance equipment and at times, as in previous years, provide for the efficient retrieval of the occasional injured hiker. The new span will have the bottom of its girders set above the high water observed in the flooding of September 2004. Placement of the designed riprap will prevent future erosion of the abutments.

Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact Page 6 of 10 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. (See III., 10, above.) 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 January 15, 2002, 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 NCEEP 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.ne.us/ncwettands/strmgide.htm]. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2.. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at Page 7 of 10 (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form.

Erin Bronk' District Ranger Highlands Ranger District Date DECISION MEMO Trail Repairs and Relocations for Panthertown Valley Trails Highlands Ranger District Nantahala National Forest Jackson County, North Carolina The Panthertown Valley trail system is a network of high-use trails located approximately six miles northwest of Lake Toxaway, near Cashiers, NC. Portions of thpse trails and several trail bridges were damaged by heavy rains received during tropical storms which passed through North Carolina during September 8, 17 and 24, 2004. This damage occurred more often on poorly located trail sections, such as, fall-line trails, poorly located user-created trails, and braided trails. Eroding tread surfaces are a source of sediment delivery into nearby creeks and user safety is compromised due to poor tread conditions and very steep trail grades. The purpose of this project is to relocate sections of trails and replace bridges that are deemed unsafe and damaged by the heavy rains to reduce future erosion and sediment delivery into local streams. A map of the proposed trail relocations is located in the project file. DECISION I have decided to implement the following actions needed to repair, realign and relocate several sections of the Panthertown Valley trails. All undesirable or unneeded trail sections and user- created non-system trails will be obliterated using logs, tree limbs, brush, live plants, soil and/or leaf litter to hide the trail and block access to it. Check dams will be installed, as needed, in gullied areas of the obliterated trails to decrease erosion. A. Panthertown Creek Trail 450 - Realign approximately 1800 feet of trail to create a safe and sustainable grade, correct drainage problems, and to move trail from boggy areas. B. Greenland Trail 459 - Obliterate approximately 350 feet of user-created fall-line trail which descends steeply downhill. Realign the trail as needed to create a safe and sustainable grade. C. Hogback Mountain Trail 453 - Construct two low-water crossings by adding rock to the creek bed which will allow maintenance vehicles to pass through the stream with little disturbance. Relocate a combined length of approximately 1,300 feet of trail in two unconnected locations. These relocations are needed to create a safe and sustainable grade and to move the trail out of gullied areas. D. Little Green Mountain Trail 485 - Relocate approximately 100 feet of trail around boggy areas. Use timber from puncheons destroyed during high water flows to construct a retaining wall approximately 40 feet long. The retaining wall will be located on a steep, eroding section of the trail past the trail junction to Schoolhouse Falls. E. Little Green Valley Trail 484 - Relocate approximately 120 feet of trail in two locations to move it out of old road cut banks and to correct drainage problems (add dips, water bars, and lead-outs). F. Greenland/Devils Elbow Trail 486 - Between Trails 474A and 451. This section of trail will be removed from the trail system by obliterating 300 feet of this trail at each end. These 300 foot sections may also be used for borrow material. G. Install three trail bricWes - Greenland Creek Trail Bridges 451-0.3 and 451-0.0, and Panthertown-Sassafras Gap 448-0.1. H. Schoolhouse Falls Trail 452 - Relocate trail around boggy area with a boardwalk to be removed. This trail is a short section off of Little Green Mountain Trail 485 that provides access to Schoolhouse Falls. Since this analysis began the Forest Service has renamed this section of trail. It is now part of the Little Green Mountain Trail 485. .tr IMPLEMENTATION DATE AND ADMINISTRATIVE REVIEW OR APPEAL OPPORTUNITIES This decision may be implemented immediately upon signature by the deciding officer. This decision is not appealable pursuant to 36 CFR 215.12 (f).
