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 m 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 m 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 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 m 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 m accordance with the requirements of the Sedimentation Pollution Control Act 4 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 5 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 6 The post construction removal of any temporary bridge structures must return the project site to its preconstruction contours and elevations The impacted areas shall be revegetated with appropriate native species 7 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 8 Bridge deck drains shall not discharge directly into the stream Stormwater shall be directed across the bridge and pre treated through site appropnate 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 Mr J B Setzer P E November 7 2012 Page Three 9 Bridge piles and bents shall be constructed using driven piles(hammer or vibratory) or drilled shaft construction methods More specifically jetting or other methods of pile driving are prohibited without prior written approval from NCDWQ first 10 No drill slurry or water that has been in contact with uncured concrete shall be allowed to enter surface waters This water shall be captured treated and disposed of properly 11 All pile driving or drilling activities shall be enclosed in turbidity curtains unless otherwise approved by NCDWQ in this certification 12 All bridge construction shall be performed from the existing bridge temporary work bridges temporary causeways or floating or sunken barges If work conditions require barges they shall be floated into position and then sunk The barges shall not be sunk and then dragged into position Under no circumstances should barges be dragged along the bottom of the surface water 13 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 14 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 15 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 16 Rip rap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes aquatic life passage Bioengineenng boulders or structures should be properly designed sized and installed 17 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 18 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 19 The Permittee shall ensure that the final design drawings adhere to the permit and to the permit
