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 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 shall not be placed in wetlands or waters unless 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 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 i 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 4 The channel relocation will be constructed in a dry work area and stabilized before stream flows are diverted into the new channel Stream banks shall be matted with coin fiber matting Vegetation used for bank stabilization shall be limited to native riparian vegetation and should include establishment of a vegetated buffer on both sides of the relocated channel to the maximum extent practical Also rip rap may be allowed if it is necessary to maintain the physical integrity of the stream but the applicant must provide written justification and any calculations used to determine the extent of rip rap coverage requested Once the stream has been turned into the new channel it may be necessary to relocate stranded fish to the new channel to prevent fish kills 5 All work in or adjacent to stream waters shall be conducted in a dry work area Approved BMP measures from the most current version of NCDOT Construction and Maintenance Activities manual such as sandbags rock berms cofferdams and other diversion structures shall be used to prevent excavation in flowing water 6 The stream channel shall be excavated no deeper than the natural bed material of the stream to the maximum extent practicable Efforts must be made to minimize impacts to the stream banks as well as to vegetation responsible for maintaining stream bank stability Any applicable riparian buffer impact for access to stream channel shall be temporary and be revegetated with native riparian species Mr J B Setzer P E August 13 2012 Page Three 7 The dimension pattern and profile of the stream above and below the crossing shall not be modified Disturbed floodplams and streams shall be restored to natural geomorphic conditions 8 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 9 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 10 Rip rap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes aquatic life passage Bioengmeermg boulders or structures should be properly designed sized and installed 11 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 12 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 13 The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings submitted for approval 14 Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited 15 If concrete is used during construction a dry work area shall be maintained to prevent direct contact between curing concrete and stream water Water that inadvertently contacts uncured concrete shall not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and fish kills 16 No rock sand or other materials shall be dredged from the stream channel except where authorized by this certification 17 A copy of this Water Quality Certification shall be maintained on the construction site at all times In addition the Water Quality Certification and all subsequent modifications if any shall be maintained with the Division Engineer and the on site project manager 18 All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3 1
