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 A roved Units Plan Location or Reference Stream 160 feet Lon Branch 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. f Long Branch Stream Stabilization Page 3 of 6 May 12, 2006 4. 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. 5. 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. 6. 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. 7. 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. 8. 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 Long Branch Stream Stabilization Page 4 of 6 _ May 12, 2006 be modified by widening the stream channel or changing its depth. No backfilling of stream bed materials is allowed under this authorization. 9. 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. 10. 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. 11. 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. 12. Disturbed stream banks and a 25-foot vegetated zone (as required under the Trout 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 25 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.) 13. 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. 14. 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. Long Branch Stream Stabilization Page 5 of 6 May 12, 2006 r 15. 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. 16. 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 1506 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.

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. n,...., c ..ro 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/ncwetiands/strrnizide.html. 1.

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. The proposed projects will restore unstable stream channel areas. 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. n--- c .,ro 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.htmi. 1.
