Compensatory Mitigation Using Onsite Restoration and Preservation Mitigation must be provided for the proposed impacts. According to your conceptual mitigation plan, referenced on page 3 of the Public Notice issued by the U.S. Army Corps of Engineers on January 25, 2007, and received by the DWQ on January 29, 2007, you will be restoring 570 Linear feet of onsite perennial stream, preserving 37,891 linear feet of perennial stream with a minimum 25-foot buffer, and preserving 0.587 acres of wetland with a minimum 25-foot buffer. never, the DWQ will require the receipt of and approval for yctux final mitigation plan before the proposed impacts referenced in this Certification may occur. 9. Turbidity Standard The turbidity standard of 50 NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 2B .0200. Appropriate sediment and erosion control practices must be used to meet this standard. Shuld there be a violation of the turbidity standard, all work shall cease until. such a point the measures are implemented to protect surface waters form further violations. 10. Construction Stormwater Permit NCGO10000 Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an NPDES General Stormwater permit (NCGO10000) administered by DWQ is automatically issued to the project. This General Permit allows Stormwater to be discharged during land disturbing construction activities as stipulated by conditions in the permit. If your project is covered by this permit [applicable to construction projects that disturb one (1) or more acres], full compliance with permit conditions including the sedimentation control plan, seIf- monitoring, record keeping and reporting requirements are required. A copy of this permit Shane Robichaud and Lonesome Valley Development, LLC Page 5 of 7 February 23, 2007 and monitoring report forms may be found at http://h2o.enr.state.nc.us/su/Forms Documents.htm. 11. Deed Notifications Deed notifications or similar mechanisms shall be placed on all retained jurisdictional wetlands, waters and protective buffers in order to assure compliance for future wetland, water and buffer impact. These mechanisms shall be put in place prior to impacting any wetlands, waters and/or buffers approved for impact under this Certification Approval and Authorization Certificate: 12. Temporary Fills All temporary fill and culverts shall be removed and the impacted area returned to the original grade, including each stream's original cross sectional dimensions, planform pattern, and longitudinal bed and bed profile after construction is complete or within 6 months of the establishment of the crossing, which ever is sooner, and the various sites shall be stabilized with natural woody vegetation (except for the maintenance areas of permanent utility crossings) and restored to prevent erosion. If the crossings are not completely removed and restored as described above within the specified time above, additional written approval from this Office must be obtained to modify this condition. 13. Culvert Installation Culverts required for this project shall be installed in such a manner that the original stream profiles are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and longitudinal prof le) must be maintained above and below locations of each culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re-established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed correctly. Culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the stream up or down stream of the culverts}. Existing stream dimensions (including the cross section dimensions, pattern and longitudinal profile) shall be maintained above and below locations of each culvert. Therefore, you must provide plans with adequate details that indicate that the current stability of the stream will be maintained or enhanced. You must receive written approval from this Office for the above plans before the culvert(s) is installed. Culvert(s) must be installed according to approved plans. The establishment of native, woody vegetation and other soft stream bank stabilization techniques must be used where practicable instead of rip-rap or other bank hardening methods. If rip-rap is necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of Water Quality. Shane Robichaud and Lonesome Valley Development, LLC Page 6 of 7 February 23, 2007 14. Riparian Zone Replanting Replanting of vegetation within disturbed areas located within 25 feet of the streambanlc associated with any land disturbing activity, repair, replacement and/or maintenance must be done in a manner consistent with the Guidelines for Riparian Buffer Restoration immediately following construction. (Please see attached.) 15. Culverts that are less than 48 inches in diameter should be installed with 20% of the diameter of the culvert placed below the level of the stream bottom to allow the accumulation of stream bed materials and to facilitate aquatic life passage during periods of low stream flow. Larger diameter culverts should be placed 1 foot below the stream bottom. Culverts should be placed in the main flow channel (i.e. thalweg). Partial burial of culverts in this manner also may require increasing their size to accommodate flow requirements. 16. If concrete is used during construction (e.g., headwalls), a dry work area must be maintained to prevent direct contact between curing concrete and stream water. Water that inadvertently contacts live concrete should not be discharged to surface waters due to the potential for water chemistry change and a fish kill. 17. Rock, sand, or other materials shall not be dredged from the stream channels except in the immediate vicinity of the crossings. Instream dredging has severe effects on aquatic life and disturbance of the natural form of the channel can cause downstream erosion problems. The natural dimension, pattern, and profile of the channels adjacent to the crossings shall not be modified by widening or changing their depths. 18. Sandbags, flexible pipe, or other diversion structures should be used to avoid excavation in flowing water. Materials used for flow diversions should be removed from the streambed after completing the construction work. Any diversion channels must be lined with fabric and/or rock. 19. Any rip-rap placed for inlet or outlet stabilization should be clean and limited to the stream bank below the high water mark and vegetation should be used above. Rip rap must not be placed in stream channels in a manner that obstructs fish passage. 20. All crossings should be constructed as close to perpendicular to the stream channels as possible to minimize stream and buffer disturbance. Road and utility alignments should be set-back as far as possible from stream channels to minimize sedimentation and buffer disturbance. 2I . Riparian vegetation, especially trees and shrubs, should be preserved as much as possible: Native woody vegetation (e.g., rhododendron, dog hobble, silky dogwood, sycamore, river birch, red maple) should be reestablished upstream and downstream of the stream crossings if it is removed during construction to provide bank stability and shading. We encourage the use of native plants that must be removed from permanently disturbed areas. Shane Robichaud and Lonesome Valley Development, LLC Page 7 of 7 February 23, 2007 22. 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. 23. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. 24. 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 Oversight/Express Review Permitting Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699- 1650. 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. If this Certification is unacceptable to you, you have the right to an adjudicatory hearing upon written request within sixty (60) days following receipt of this Certification. This request must be in the form of a written. petition conforming to Chapter 150B of the North Carolina General Statutes and filed with the Office of Administrative Hearings, 6714 Mail -Service Center, Raleigh, N.C. 27699-6714.

Construction will proceed upstream to do+vnstreanr. Temporan sand bag coffer dams will be installed upstream of each work area and flow hr the work reach will be diverted with a pump and piping. The length of each diversion Tvill be approximately 31111 ro X00 Iineaz feet. 3. Temporary stream crossings will be installed at locations shown on the plans. 4. Reach 2 construction imoh'es both enhancement to the existing channel and creation of new off-line channel. Flow diversions will be staged according to lengths of sub- rcaches and site constraints. 5 Reach 3 construction will be similar to that proposed for reach 1. 6. Clearing and grubbing within the grading limits will be performed so as to limit sediment migration off-site. Logs and root wads from trees larger than 10 inches in diameter will be stockpiled for use in in-stream structures. 7. In areas wfiere new channel will be constructed salvageable native vegetation (doghobble, rhododendron; yellowrool. etc.), mats will be harvested for transplanting. These mats will be excavated and moved to the banks of the new channel sections. 8. The new channel sections will be stabilized with in-stream sWctures, erosionconttol matting and seed before turning water into these sections. Compacted soil channel plugs gill be installed in areas where the new channel diverges from the original channel and the original, abandoned channel sections will be backf lied. 9. Dewatering of off-line channel sections is expected to be minor. Any water pumped during dewutering operations in the off-lute sections will be diverted through a sediment fdter before being discharged into the downstream reach. 10. Earthwork will be staged such that no more channel will be disturbed than can be stabilized by the end of the work day or before flow is diverted into a newclrannel segment. I1. Excess soil materials will be stockpiled outside the lbodplain it the staging areas, with silt fence installed on the stream side(s) of the base of the stockpiles and maintained when sediment has accumulated above one third of the height of the silt fence andlor the silt fence has failed. This excess material will be hauled outside the consen anon easement or used to backfill abandoned channel before demobilization. 12. The flow diversions and stream crossings will be removed when no longer needed and the banks in these areas stabilized with seeding and matting. 13. Bank and floodplain vegetation, including brush materials and live stakes, will be installed during dormant season, November to April. ld. Construction entrances; staging areas and silt fences will be removed once planting is complete or once they are no longer needed.
