292 160 Total Stream Impact for Project 160 linear feet Temporary Impacts for Project 132 linear feet The project should be constructed in accordance with your application dated December 28 2007 (received January 9 2008) including the environmental commitments made in the application letter After reviewing your application we have decided that these impacts are covered by General Water Quality Certification No 3704 corresponding to the U S Army Corps of Engineers General Permit Number 31 In addition you should acquire any other federal state or local permits before you proceed with your project including (but not limited to) Sediment and Erosion Control Non Discharge and Water Supply Watershed regulations Please note that new 401 Water Quality Certifications went into effect on November 1, 2007 These Certifications contain additional requirements that were not in the old certifications You are strongly urged to review these new certifications (attached) and become familiar with their requirements This approval is valid solely for the purpose and design described in your application (unless modified below) Should your project change you must notify the DWQ and submit 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 wetland fills for this project (now or in the future) exceed one acre or if total impacts to streams (now or in the future) exceed 150 linear feet compensatory mitigation may be required as described in 15A NCAC 2H 0506 (h) (6) and (7) For this approval to be valid you must follow the conditions listed in the attached certification and any additional conditions listed below NorthCnrolin,i vVaturally North

/Affirmative Action Employer Dr Gregory J Thorpe PhD February 18 2008 Page Two Condition(s) of Certification 1 There shall be no excavation from or waste disposal into jurisdictional wetlands or waters associated with this permit without appropriate modification Should waste or borrow sites, or access roads to waste or borrow sites be located in wetlands or streams compensatory mitigation will be required since that is a direct impact from road construction activities 2 Sediment and erosion control measures s all nofbe placed -in wetlands or wags u ess otherwise - approved -by this- Certification If placement of sediment and erosion control devices in wetlands and waters is unavoidable they shall be removed and the natural grade restored upon completion of the project 3 The permittee shall use /Design Standards in Sensitive Watersheds/ [15A NCAC 4B 0124 (a) (e)] Temporary cover (wheat millet or similar annual grain) or permanent herbaceous cover shall be planted on all bare soil within fifteen (15) working days of ground disturbing activities to provide long term erosion control Erosion control mating shall be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas Steep slopes are defined as those slopes graded at an angle which cannot retain vegetative cover Matting should be secured in place with staples or wherever possible live stakes of native trees Straw mulch and tall fescue shall not be used in riparian areas G If multiple pipes or barrels are required they shall be designed to mimic the natural stream cross section as closely as possible including pipes or barrels at flood plain elevation and /or sills where appropriate Widening the stream shall be avoided Stream channel widening at the inlet or outlet end of stiuctures typically decreases water velocity causing sediment deposition that requires increased maintenance and disrupts aquatic life passage i In stream work and land disturbance within the 25 foot buffer zone are piohibrted during the trout spawning season of October 15 through April 15 to protect the egg and fry stages of trout from off site sedimentation during construction of the highway Compensatory Mitigation for impacts to 160 linear feet of stream is required We understand that you have chosen to perform compensatory mitigation for impacts to streams through the North Carolina Ecosystem Enhancement Program (EEP) and that the EEP has agreed to implement the mitigation for the project EEP has indicated in a letter dated December 10 2007 that they will assume responsibility for satisfying the federal Clean Water Act compensatory mitigation requirements for the above referenced project in accordance with the Tri Party MOA signed on July 22 2003 and the Dual Party MOA signed April 12 2004 7 The post construction removal of any temporary bridge structures must return the project site to its preconstruction contours and elevations The impacted area shall be revegetated with appropriate native species 3 Strict adherence to the most recent version of NCDOT s Best Management Practices For Bridge Demolition and Removal approved by the US Army Corps of Engineers is a condition of the 401 Water Quality Certification Bridge deck drains should not discharge directly into the streams Stormwater shall be directed across the bridge and pre treated through site appropriate means (grassed swales pre formed scour holes vegetated buffers etc ) before entering the stream Please refer to the most current version of Stormwater Best Management Practices Stormwater shall be managed in accordance with your State Stormwater Permit issued by the Division of Water Quality 10 For projects impacting waters classified by the NC Environmental Management Commission as Trout (Tr) High Quality Waters (HQW) or Water Supply I or II (WS I WS 11) stormwater shall be directed to vegetated buffer areas grass lined ditches or other means appropriate to the site for the purpose of pre treating stormwater runoff prior to discharging directly into streams Mowing of existing vegetated buffer areas is strongly discouraged 11 The dimension pattern and profile of the stream above and below the culverts shall not be modified Disturbed floodplains and streams shall be restored to natural geomorphic conditions 12 Native riparian vegetation (e g rhododendron dog hobble willows alders sycamores dogwoods black walnut and red maple) must be reestablished within the construction limits of the project by the end of the growing season following completion of construction 13 The use of rip rap above the Normal High Water Mark shall be minimized Any rip rap placed for stream stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage 14 Rip rap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes aquatic life passage Bioengineering boulders or structures should be properly designed sized and installed 15 Heavy equipment shall be operated from the banks rather than in the stream channels in order to minimize sedimentation and reduce the introduction of other pollutants into the stream 16 All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent contamination of stream waters from fuels lubricants hydraulic fluids or other toxic materials .'Dr aegory J Thorpe PhD February 18 2008 Page Three 17 The Permtttee shall ensure that the final design drawings adhere to the permit and to the permit drawings submitted for approval 18 Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited 19 No rock sand or other materials shall be dredged from the stream channel except where authorized by this certification 20=A- copyef4hrs W atre�uah �- C- er- tification shall -be maitnaned on the construction site at all times= In-addrtian-thn-- Water Quality Certification and all subsequent modifications if any shall be maintained with the Division Engineer and the on site project manager 21 All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3 1 unless otherwise authorized by this certification 22 The outside buffer wetland or water boundary located within the construction corridor approved by this authorization shall be clearly marked by highly visible fencing prior to any land disturbing activities Impacts to areas within the fencing are prohibited unless otherwise authorized by this certification 23 The issuance of this certification does not exempt the Permittee form complying with any and all statutes rules regulations or ordinances that may be imposed by other government agencies (i e local state and federal) having jurisdiction including but not limited to applicable buffer rules stormwater management rules soil erosion and sedimentation control requirements etc 24 The P(,nnittee shall report any violations of this certification to the Division of Water Quality within 24 hours of discovery 25 Upon completion of the
