Ross Jr., Secretary North Carolina Department of Environment and Natural Resources o ? `*- Alan W. Klimek, P.E. Director Division of Water Quality September 11, 2006 DWQ Project # 06-1251 Macon County Marisue Hilliard, Forest Supervisor National Forests in North Carolina Post Office Box 2750 Asheville, NC 28802-2750 Subject Property: LBJ Bridge Replacement Approval of 401 Water Quality Certification with Additional Conditions Dear Mr. Hilliard: You have our approval, in accordance with the attached conditions and those listed below, to place fill within or otherwise impact approximately 265 linear feet of streams for the purpose of stream stabilization and access repair / replacement at the subject property, as described within your application received by the N.C. Division of Water Quality (DWQ) on August 25, 2006. After reviewing your application, we have decided these impacts are covered by General Water Quality Certification Number(s) 3495 (GC3495). The Certification (s) allows you to use Nationwide Permit(s) 13 / 27 when issued by the US Army Corps of Engineers (USACE). In addition, you should obtain or otherwise comply with any other required federal, state or local permits before you go ahead with your project including (but not limited to) Erosion and Sediment Control, Non-discharge, and stormwater regulations. Also, this approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA Permit. This approval is for the purpose that you described in your application. If you change your project beyond this approval, you must notify us and you may be required to send us a new application. If the property is sold, the new owner must be given a copy of this Certification and approval letter and is thereby responsible for complying with all conditions. If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). This approval requires you to follow the conditions listed in the attached certification and any additional conditions listed below. The Additional Conditions of the Certification are: 401 Wetlands Certification Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786 / FAX 919-733-6893 / Internet: http:/lh2o. en r. state. nc. us/ncwetlands An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper LBJ Bridge Replacement Page 2 of 6 September 11, 2006 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 Plan Location or Reference Approved (Units) Stream Approximately Wayah Creek 265 (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. LBJ Bridge Replacement Page 3 of 6 September 11, 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 shall 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. LBJ Bridge Replacement Page 4 of 6 September,l 1, 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 25-foot vegetated zone (as required under the Trout Buffer regulations) 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. V LBJ Bridge Replacement Page 5 of 6 September 11, 2006 i 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 1508 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.

If a stream has no name, list as UT (unnamed tributary) to the nearest downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at www.uses.gov. Several intemet sites also allow direct download and printing of USGS maps (e.g., www.topozone.coni, www.mapgLiest.com, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 265' Note: J-Hook vanes are in-stream work within the 265 linear feet of stream impact area. Page 8 of 12 4. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.) below: Open Water Impact ' Site Number (indicate on ma Type of Impact* Area of Impact (acres) Name of Waterbody (if applicable) Type of Waterbody (lake, pond, estuary, sound, bay, ocean, etc. None List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. Pond Creation 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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): 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 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. Entire site lies within the floodplain making it impossible to locate the structure out of the floodplain. Since the site is very flat, raising the roadway _profile to allow passage of the 100 year flows would require very steep grades 8! +) due to adjacent structures and would result in high embankments creating a "dam" which itself would be subject to erosion. Previous storm waters have resulted in the structure failure. Proposed design will protect the embankments along the abutments (and the adjacent stream) to minimize or prevent future erosion and resulting embankment failure. The removal of gabions and deteriorated stone wall will reduce the channelization effect. Sloping the stream embankments in combination with seeding and shrub plantings will encourage natural stream action. J-hook vane installation will improve in-stream habitat and protect bridge abutments. Page 9 of 12 VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at httl):/ih2o.enr.state.nc.us/newetlands/strmgide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN.

MARISUE HILLIARD Forest Supervisor Caring for the Land and Serving People Printed on Recycled Paper ?? REVISED SPECIAL PROJECT SPECIFICATIONS FOR LBJ BRIDGE REPLACMENT BANK STABILIZATION PROJECT STREAM RESTORATION SPECIFICATIONS EQUIPMENT AND OPERATOR SPECIFICATIONS A) Manner of Construction -Excavation will be done in a manner which will minimize sedimentation in the stream channel. Silt fence will be installed downstream of the construction area to reduce the risk of sediment entering the stream. B) Equipment Operator Performance - Equipment operators shall be experienced and competent in the use of the equipment to which they are assigned. They shall be expected to demonstrate a level of proficiency with the equipment which enables them to be productive in all aspects of stream restoration work. Operators will be instructed by the construction inspector as to the desired result of construction activities. Operators will be responsible for determining how best to use equipment to achieve the desired results. Chain saw operators will be required to cut trees, limbs and root masses as necessary to facilitate the removal and placement of debris in the stream. C) 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 construction inspector. Equipment shall be new or of low hours and be maintained to prevent fuel, oil and lubricant spills in the vicinity of the stream. Refueling, repairs and lubrication will be performed at a safe distances from the stream and only at locations approved by the construction inspector where water is controlled by runoff control measures. D) Safety Considerations - At work sites, where equipment will be operated on Forest Roads, flagman 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. The contractor will be responsible for the implementation of these measures. IN-STREAM STRUCTURES SPECIFICATIONS Structure Stone Description The work covered by this section consists of furnishing, stockpiling, placing and maintaining approved stone to be utilized to construct rock and log vanes, root wad structures, the step-pool structures, stream crossings, sediment and erosion control measures for use in locations as directed by the Designer. The quantity of stone may be increased, decreased, or eliminated entirely at the direction of the Designer. Such variations in quantity will not be considered as alterations in the details of construction or a change in the character of the work. Materials Stone for Coarse Aggregate, No. 57 Stone, "Rip Rap-Class A", "Rip Rap-Class B", "Boulder-Footer", and "Boulder- Header" shall consist of blasted stone or other stone approved by the Designer. The stone shall be sound, tough, dense, resistant to the action of air and water, and suitable in all other respects for the purpose intended. All stone shall meet the approval of the Designer. While no specific gradation is required, the various sizes of the stone shall be equally distributed within the required size range. The size of an individual stone particle will be determined by measuring its long dimension. Acceptance Criteria for Stone REQUIRED STONE LONG DIMENSION SIZES (INCHES) CLASS Minimum Average Maximum A 2 4 6 B 5 8 12 Boulder-Footer 72 84 NA 36" x 36" x 72" Boulder-Header 72 84 NA 36" x 36" x 72" No more than 5 percent of the material furnished can be less than the minimum size specified, more than 10 percent of the material can exceed the maximum size specified. Footer boulders of approximate dimension 48x48x72 inches shall be individually picked for use in the structures. Header boulders of approximate dimension 48x48x72 inches shall be individually picked for use as the headers in the structures. Boulders shall be relatively flat on either side in the same dimension, preferably the long dimension. Consbvctilon The Contractor shall place stone, in locations shown on the construction plans to the thickness, widths, and lengths as shown on the construction plans or directed by the Designer. All stone shall be placed neatly and uniformly with an even surface to form an in-stream structure or a sediment and erosion control device or in accordance with the construction plans and special provisions, and shall meet the approval of the Designer. Method of Measurement The quantity of stone required to construct the structures or sediment and erosion control measures detailed in these special provisions will be incidental to those bid items. However, field conditions may warrant the need for additional stone greater than the quantity specified or detailed for each bid item. The quantity of stone that has been incorporated into the project, as directed or approved by the Designer, which exceeds 110% of the quantity required for each bid item will be measured by weight. Measured by weight will require the quantity to be weighed in trucks on certified platform scales. Stone that was previously stockpiled for other bid items will not be measured a second time for this provision. Basis of Payment When field conditions dictate the need for additional quantity greater than 10% of the bid item, the quantity of stone measured as provided above, will be paid for at the contract unit price per ton for "Misc. Coarse Aggregate, No. 57 Stone", "Misc. Rip Rap-Class A", "Misc. Rip Rap-Class B", and "Misc. Boulder". Such price and payment will be full compensation for all work covered by this section, including but not limited to furnishing, weighing, stockpiling, re-handling, placing, and maintaining the stone and disposal of any materials not incorporated into the project if directed by the Designer. Payment will be made under: Misc. Coarse Aggregate, No. 57 Stone .............................................................:...................................TON Misc. Rip Rap-Class A ......................................................................................................................TON Misc. Rip Rap-Class B ......................................................................................................................TON Misc. Boulder ....................................................................................................................................TON Rock J-hook Vane Description A Rock J-hook Vane is primarily used for grade control. This structure serves to maintain the integrity of the upstream riffle while promoting scouring in the downstream pool. The design shape is roughly that of the letter "J" with the apex located on the upstream side at the foot of the riffle. Footer boulders are placed in the channel bottom for stability. Header boulders are then placed on top of these footer boulders. Header boulders in the middle of the channel are at approximately the same depth as the riffle. On one side of the channel, wing boulders are placed at an angle to the stream bank, gradually inclining in elevation until they are located near the bankfull surface directly adjacent to the stream bank. On the other side, the structure turns downstream to create the hook of the "J", matching the slope of the wing until it goes directly toward the bank as a sill. Water flowing downstream is forced over these boulders towards the middle and opposite side of the channel, effectively turning flow and scouring out a pool below. Boulders placed at the apex hold back streambed material and prevent it from washing downstream. The quantity of Rods J-hook Vanes may be increased, decreased, or eliminated entirely at the direction of the Designer. Such variations in quantity will not be considered as alterations in the details of construction or a change in the character of the work (See Rods J-hook Vane detail below). Materials All materials shall meet the requirements of boukler as outlined in Special Provision "Structure Stone". Back fill material shall be obtained from the stream channel bed, likely from the constructed pool. Installation A trench shall be dug in such a manner that the footer boulders, the hook header boulders and at least V3 of the wing boulders are buried beneath the bed surface elevation. Refer to the construction plans for exact installation guide and locations of vane to be installed. An excavator, with a bucket that includes a hydraulic thumb, shall be used to place boulders under the supervision of Designer. Footer boulders shall be placed first with header boulders placed on top prior to any back filling of the trench. Boulders shall be selected and positioned such that they butt tightly together and there are multiple contact points between all boulders (flat smooth surfaces that fit together). In the center portion of the channel, the header boulder shall be placed such that the top of the header boulder is at an elevation equal to the bed elevation. The header boulders in the side, or wing, portion shall be placed in such a manner as they slope up from bed elevation to bankfull or below at a 2 to 7 percent slope or as shown in detail. Header and footer boulders at both banks shall be tied in securely to the bank in such a way that eliminates the possibility of water diverting around them. A rock sill shall be utilized to further prevent water from cutting around the structure. The area between the stream bank and vane on the upstream side of the structure will be bacldilled with stream bed material. Structures shall be built to the approval of the Designer. The Designer may adjust the number and placement of structures in the field. A ROCK J-HOOK VANE DETAIL a FOOTER r ROCK F TT. I. J NON-WOVEN !

Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. Pond Creation 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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): 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 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. Entire site lies within the floodplain making it impossible to locate the structure out of the floodplain. Since the site is very flat, raising the roadway profile to allow passage of the 100 year flows would require very steep grades (80/o+) due to adjacent structures and would result in high embankments creating a "dam" which itself would be subject to erosion. Previous storm waters have resulted in the structure failure. Proposed design will protect the embankments along the abutments (and the adjacent stream) to minimize or prevent future erosion and resulting embankment failure. The removal of gabions and deteriorated stone wall will reduce the channelization effect. Sloping the stream embankments in combination with seeding and shrub plantings will encourage natural stream action. J-hook vane installation will improve in-stream habitat and protect bridge abutments. Page 9 of 12 VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete.

MARISUE HILLIARD Forest Supervisor Caring for the Land and Serving People Printed on Recycled Paper REVISED SPECIAL PROJECT SPECIFICATIONS FOR LBJ BRIDGE REPLACMENT BANK STABILIZATION PROJECT STREAM RESTORATION SPECIFICATIONS EQUIPMENT AND OPERATOR SPECIFICATIONS A) Manner of Construction -Excavation will be done in a manner which will minimize sedimentation in the stream channel. Silt fence will be installed downstream of the construction area to reduce the risk of sediment entering the stream. B) Equipment Operator Performance - Equipment operators shall be experienced and competent in the use of the equipment to which they are assigned. They shall be expected to demonstrate a level of proficiency with the equipment which enables them to be productive in all aspects of stream restoration work. Operators will be instructed by the construction inspector as to the desired result of construction activities. Operators will be responsible for determining how best to use equipment to achieve the desired results. Chain saw operators will be required to cut trees, limbs and root masses as necessary to facilitate the removal and placement of debris in the stream. C) 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 construction inspector. Equipment shall be new or of low hours and be maintained to prevent fuel, oil and lubricant spills in the vicinity of the stream. Refueling, repairs and lubrication will be performed at a safe distances from the stream and only at locations approved by the construction inspector where water is controlled by runoff control measures. D) Safety Considerations - At work sites, where equipment will be operated on Forest Roads, flagman 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. The contractor will be responsible for the implementation of these measures. IN-STREAM STRUCTURES SPECIFICATIONS Structure Stone Description The work covered by this section consists of fumishing, stockpiling, placing and maintaining approved stone to be utilized to construct rock and log vanes, root wad structures, the step-pool structures, stream crossings, sediment and erosion control measures for use in locations as directed by the Designer. The quantity of stone may be increased, decreased, or eliminated entirely at the direction of the Designer. Such variations in quantity will not be considered as alterations in the details of construction or a change in the character of the work. Materials Stone for Coarse Aggregate, No. 57 Stone, "Rip Rap-Class A", "Rip Rap-Class B", "Boulder-Footer", and "Boulder- Header" shall consist of blasted stone or other stone approved by the Designer. The stone shall be sound, tough, dense, resistant to the action of air and water, and suitable in all other respects for the purpose intended. All stone shall meet the approval of the Designer. While no specific gradation is required, the various sizes of the stone shall be equally distributed within the required size range. The size of an individual stone particle will be determined by measuring its long dimension. Acceptance Criteria for Stone REQUIRED STONE LONG DIMENSION SIZES (INCHES) CLASS Minimum Average Maximum A 2 4 6 B 5 8 12 Boulder-Footer 72 84 NA 36" x 36" x 72" Boulder-Header 72 84 NA 36" x 36" x 72" No more than 5 percent of the material furnished can be less than the minimum size specified, more than 10 percent of the material can exceed the maximum size specified. Footer boulders of approximate dimension 48x48x72 inches shall be individually picked for use in the structures. Header boulders of approximate dimension 48x48x72 inches shall be individually picked for use as the headers in the structures. Boulders shall be relatively flat on either side in the same dimension, preferably the long dimension. Construction The Contractor shall place stone, in locations shown on the construction plans to the thickness, widths, and lengths as shown on the construction plans or directed by the Designer. All stone shall be placed neatly and uniformly with an even surface to fort an in-stream structure or a sediment and erosion control device or in accordance with the construction plans and special provisions, and shall meet the approval of the Designer. Method of Measurement The quantity of stone required to construct the structures or sediment and erosion control measures detailed in these special provisions will be incidental to those bid items. However, field conditions may warrant the need for additional stone greater than the quantity specified or detailed for each bid item. The quantity of stone that has been incorporated into the project, as directed or approved by the Designer, which exceeds 110% of the quantity required for each bid item will be measured by weight. Measured by weight will require the quantity to be weighed in trucks on certified platform scales. Stone that was previously stockpiled for other bid items will not be measured a second time for this provision. Basis of Payment When field conditions dictate the need for additional quantity greater than 10% of the bid item, the quantity of stone measured as provided above, will be paid for at the contract unit price per ton for "Misc. Coarse Aggregate, No. 57 Stone", "Misc. Rip Rap-Class A", "Misc. Rip Rap-Class B", and "Misc. Boulder". Such price and payment will be full compensation for all work covered by this section, including but not limited to furnishing, weighing, stockpiling, re-handling, placing, and maintaining the stone and disposal of any materials not incorporated into the project if directed by the Designer. Payment will be made under: Misc. Coarse Aggregate, No. 57 Stone .................................................................................................TON Misc. Rip Rap-Class A ......................................................................................................................TON Misc. Rip Rap-Class B ......................................................................................................................TON Misc. Boulder ....................................................................................................................................TON Rock J-hook Vane Description A Rock J-hook Vane is primarily used for grade control. This structure serves to maintain the integrity of the upstream riffle while promoting scouring in the downstream pool. The design shape is roughly that of the letter "J" with the apex located on the upstream side at the foot of the riffle. Footer boulders are placed in the channel bottom for stability. Header boulders are then placed on top of these footer boulders. Header boulders in the middle of the channel are at approximately the same depth as the riffle. On one side of the channel, wing boulders are placed at an angle to the stream bank, gradually inclining in elevation until they are located near the bankfull surface directly adjacent to the stream bank. On the other side, the structure turns downstream to create the hook of the "J", matching the slope of the wing until it goes directly toward the bank as a sill. Water flowing downstream is forced over these boulders towards the middle and opposite side of the channel, effectively turning flow and scouring out a pool below. Boulders placed at the apex hold back streambed material and prevent it from washing downstream. The quantity of Rock J-hook Vanes may be increased, decreased, or eliminated entirely at the direction of the Designer. Such variations in quantity will not be considered as alterations in the details of construction or a change in the character of the work (See Rock J-hook Vane detail below). Materials All materials shall meet the requirements of boulder as outlined in Special Provision "Structure Stone". Back fill material shall be obtained from the stream channel bed, likely from the constructed pool. Installation A trench shall be dug in such a manner that the footer boulders, the hook header boulders and at least 1/3 of the wing boulders are buried beneath the bed surface elevation. Refer to the construction plans for exact installation guide and locations of vane to be installed. An excavator, with a bucket that includes a hydraulic thumb, shall be used to place boulders under the supervision of Designer. Footer boulders shall be placed first with header boulders placed on top prior to any back filling of the trench. Boulders shall be selected and positioned such that they butt tightly together and there are multiple contact points between all boulders (flat smooth surfaces that fit together). In the center portion of the channel, the header boulder shall be placed such that the top of the header boulder is at an elevation equal to the bed elevation. The header boulders in the side, or wing, portion shall be placed in such a manner as they slope up from bed elevation to bankfull or below at a 2 to 7 percent slope or as shown in detail. Header and footer boulders at both banks shall be tied in securely to the bank in such a way that eliminates the possibility of water diverting around them. A rock sill shall be utilized to further prevent water from cutting around the structure. The area between the stream bank and vane on the upstream side of the structure will be backfilled with stream bed material. Structures shall be built to the approval of the Designer. The Designer may adjust the number and placement of structures in the field.

Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. Pond Creation 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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): 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 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. Entire site lies within the floodplain making it impossible to locate the structure out of the floodnlain. Since the site is very flat raising the roadway profile to allow passage of the 100 year flows would require very steep grades (8%+) due to adjacent structures and would result in high embankments creating a "dam" which itself would be subject to erosion. Previous storm waters have resulted in the structure failure. Proposed design will protect the embankments along the abutments (and the adjacent stream) to minimize or prevent future erosion and resulting embankment failure. Stream diversion through containment (piping) through this section will allow the work to proceed without contamination to downstream waters. Restored channel dimensions and profile will be determined by evaluating appropriate, nearby stable or nearly stable reference sections. The temptation to provide a wide shallow channel will be voided. Temporary and or permanent vegetation will be planted on all bare soil within 15 days or specified amount) of ground disturbing activities. See attached Stream Diversion and Stabilization Plan. Page 5 of 8 VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): Page 6 of 8 Amount of buffer mitigation requested (square feet): Amount of Riparian wetland mitigation requested (acres): Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): IX.

(please secif ) 1 riprap walls 260 Wayah Creek 38' Perennial Ltst each impact separately and identify temporary impacts. Impacts include, but are not limited to: culverts and associated rip-rap, dams (separately list impacts due to both structure and flooding), relocation (include linear feet before and after, and net losstgain), stabilization activities (cement wall, rip-rap, crib wall, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included. ** Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at www.usgs.goy. Several internet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com, www.mal2quest.com, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 260' Page 4 of 8 4. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.) below: Open Water Impact Site Number (indicate on ma) Type of Impact* Area of Impact (acres) Name of Waterbod (if applicable) y Type of Waterbody (lake, pond, estuary, sound, bay, ocean, etc.) None * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. Pond Creation 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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): 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 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. Entire site lies within the floodplain making it impossible to locate the structure out of the floodalain Since the site is very flat raising the roadway profile to allow passage of the 100 year flows would require very steep grades (8%+) due to adjacent structures and would result in high embankments creating a "dam" which itself would be subject to erosion. Previous storm waters have resulted in the structure failure Proposed design will protect the embankments along the abutments (and the adjacent stream) to minimize or prevent future erosion and resulting embankment failure Stream diversion through containment (piping) am through this section will allow the work to proceed without contamination to downstream waters. Restored channel dimensions and profile will be determined by evaluating appropriate, nearby stable or nearly stable reference sections The temptation to provide a wide shallow channel will be voided Temporary and or permanent vegetation will be planted on all bare soil within 15 days (or specified amount) of ground disturbing activities. See attached Stream Diversion and Stabilization Plan. Page 5 of 8 VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strm.gide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN.

Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: Flat site with a temporary bridge in place of structure that washed out during Hurricane Frances. Boarding school and associated buildings g the banks. See Attachments Page 2 of 8 10. Describe the overall project in detail, including the type of equipment to be used: Relocate existing temporary bridge approximately 20' upstream of current location for detour crossing. Detour will require temporary fill and placement of gavel protective roadbed on existing grassy and pavement areas. Temporary diversion of stream for sediment control purposes to be provided by use of temporary pipes and portable sediment tank. Construct two new abutments (on piles) with wingwalls along current alignment approximately 5' behind the previous abutments and at 15° skew. New superstructure with approaches on fill to provide passage of 50 year water storm flows. Equipment: WB-40's, earth movers, dump trucks, cranes. All areas disturbed during construction and for the detour to be returned to their orijainal state. See Attachment 11. Explain the purpose of the proposed work: Replace temporary bridge with permanent structure. Current temporary bridge provides access to boarding school (job corps center) after Hurricane Frances eroded previous abutment foundation resulting in the failure of the superstructure.

(please seci ) 1 riprap walls 260 Wayah Creek 38' Perennial * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: culverts and associated rip-rap, dams (separately list impacts due to both structure and flooding), relocation (include linear feet before and after, and net loss/gain), stabilization activities (cement wall, rip-rap, crib wall, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included. ** Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at www.us2s.gov. Several internet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com, www.mal2quest.com, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 260' Page 4 of 8 4. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.) below: Open Water Impact Site Number (indicate on ma) Type of Impact* Area of Impact (acres) Name of Waterbody (if applicable) Type of Waterbody (lake, pond, estuary, sound, bay, ocean, etc.) None * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. Pond Creation 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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): 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 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. Entire site lies within the floodplain making it impossible to locate the structure out of the floodplain. Since the site is very flat, raising the roadway profile to allow passage of the 100 year flows would require very steep grades (8%+) due to adjacent structures and would result in high embankments creating a "darn' 'which itself would be subject to erosion. Previous storm waters have resulted in the structure failure. Proposed design will protect the embankments along the abutments (and the adjacent stream) to minimize or prevent future erosion and resulting embankment failure. Stream diversion through containment (piping) gh this section will allow the work to proceed without contamination to downstream waters. Restored channel dimensions and profile will be determined by evaluating appropriate, nearby stable or nearly stable reference sections. The temptation to provide a wide shallow channel will be voided. Temporary and or permanent vegetation will be planted on all bare soil within 15 days (or specified amount) of ground disturbing activities. See attached Stream Diversion and Stabilization Plan. Page 5 of 8 VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strm,g,ide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wm/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): Page 6 of 8 Amount of buffer mitigation requested (square feet): Amount of Riparian wetland mitigation requested (acres): Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): IX. Environmental Documentation (required by DWQ) Does the project involve an expenditure of public (federal/state) funds or the use of public (federal/state) land? Yes ® No ? If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ? No ? N/A If yes, has the document review been fmalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ? No ? N/A X .Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ? No ® If you answered "yes", provide the following information: Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Required Zone* Impact (square feet) Multiplier Mitigation 1 3 2 1.5 Total * Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an additional 20 feet from the edge of zone 1. Page 7 of 8 If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0260. XI. Stormwater (required by DWQ) Describe impervious acreage (both existing and proposed) versus total acreage on the site. Discuss stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. Impervious acreage will not change. Erosion and sedimentation prevention and control will be maintained throughout this project primarily through proper water management, construction sequencing, proper staging, and stockpiling material, and the 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. XII. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. Temporary portable facilities will be required for the duration of the project. XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H.0500) or any Buffer Rules? Yes ? No Is this an after-the-fact permit application? Yes ? No XIV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control). N/A ,,p? licant/Agent's Signature Date signature is valid only if an authorization letter from the applicant is provided.)

If a stream has no name, list as UT (unnamed tributary) to the nearest downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at www.usas.gov. Several internet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com, www.mal2quest.com, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 260' Page 4 of 8 4. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.) below: Open Water Impact Site Number (indicate on ma) Type of Impact* Area of Impact (acres) (if Name applicable) Wat) Type of Waterbody (lake, pond, estuary, sound, bay, ocean, etc.) None * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. Pond Creation 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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): 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 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. Entire site lies within the floodplain making it impossible to locate the structure out of the floodplain. Since the site is very flat, raising the roadway profile to allow passage of the 100 year flows would require very steep grades (8%+) due to adjacent structures and would result in high embankments creating a "dam" which itself would be subject to erosion. Previous storm waters have resulted in the structure failure. Proposed desig- will protect the embankments along the abutments (and the adjacent stream) to minimize or prevent future erosion and resulting embankment failure. Stream diversion through containment (piping) through this section will allow the work to proceed without contamination to downstream waters. Restored channel dimensions and profile will be determined by evaluating appropriate, nearby stable or nearly stable reference sections. The temptation to provide a wide shallow channel will be voided. Temporary and or permanent vegetation will be planted on all bare soil within 15 days (or specified amount) of ground disturbing activities. See attached Stream Diversion and Stabilization Plan. Page 5 of 8 VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at htt]2://h2o.enr.state.nc.us/ncwetlands/strmgide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): Page 6 of 8 Amount of buffer mitigation requested (square feet): Amount of Riparian wetland mitigation requested (acres): Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): IX.

If a stream has no name, list as UT (unnamed tributary) to the nearest downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at www.uses.eov. Several internet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com, www.mayguest.com, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 260' Page 4 of 8 4. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.) below: Open Water Impact Site Number (indicate on ma) Type of Impact* Area of Impact (acres) Name Waterbody ) (if applicable) Type of Waterbody (lake, pond, estuary, sound, bay, ocean, etc.) None * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. Pond Creation 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.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): 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 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. Entire site lies within the floodplain making it impossible to locate the structure out of the floodplain. Since the site is very flat, raising the roadway profile to allow passage of the 100 year flows would require very steep grades (8%+) due to adjacent structures and would result in high embankments creating a "dam" which itself would be subject to erosion. Previous storm waters have resulted in the structure failure. Proposed design will protect the embankments along the abutments (and the adjacent stream) to minimize or prevent future erosion and resulting embankment failure. Stream diversion through containment (piping) , through this section will allow the work to proceed without contamination to downstream waters. Restored channel dimensions and profile will be determined by evaluating appropriate, nearby stable or nearly stable reference sections. The temptation to provide a wide shallow channel will be voided. Temporary and or permanent vegetation will be planted on all bare soil within 15 days (or specified amount) of ground disturbing activities. See attached Stream Diversion and Stabilization Plan. Page 5 of 8 VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmaide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.ne.us/wM/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): Page 6 of 8 Amount of buffer mitigation requested (square feet): Amount of Riparian wetland mitigation requested (acres): Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): IX.

If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ? No ? N/A If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ? No ? N/A X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify, )? Yes ? No ® If you answered "yes", provide the following information: Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Zone* (sqImpact uare feet) Multiplier Required 1 3 2 1.5 Total Lone 1 extends out 3U teet perpendicular from near bank of channel; "Lone 2 extends an additional 20 feet from the edge of Zone 1. Page 7 of 8 If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or.0260. XI. Stormwater (required by DWQ) Describe impervious acreage (both existing and proposed) versus total acreage on the site. Discuss stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. Impervious acreage will not change. Erosion and sedimentation prevention and control will be maintained throughout this project primarily through proper water management, construction sequencing, proper staging and stockpiling material, and the 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. XII. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. Temporary portable facilities will be required for the duration of the project. XIII.
