1598 APPROVAL of 401 Water Quality Certification with Additional Conditions Dear Dr Thorpe You have our approval in accordance with the attached conditions and those listed below to permanently impact 157 linear feet (If) (114 If for bank stabilization and 43 If for interior bent installation) and to temporarily impact 0 02 acres (causeways) of the South Fork Catawba River (Site 1) a perennial stream and to permanently impact 18 If (bank stabilization) of an unnamed tributary to the South Fork Catawba River (Site 2) a perennial stream as described in your application received by the Division of Water Quality (DWQ) on March 27 2012 The location of the project is State Road 2019 (Rocky Ford Road) in Catawba County After reviewing your application we have determined that this project is covered by Water Quality General Certification Numbers 3820 Please note that you should get any other federal state or local permits before proceeding with your project including those required by (but not limited to) Sediment and Erosion Control Non Discharge and Water Supply Watershed regulations This approval will expire with the associated 404 permit unless otherwise specified in the Water Quality Certification ,This approval is valid solely for the purpose and design that you described in your application (unless modified below) Should your project change you must notify the DWQ in writing and you may be required to 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 remain valid you must adhere to the conditions listed in the attached certification and those listed below All portions of the proposed project draining to 303(d) listed watersheds that are impaired due to turbidity shall be designed constructed and operated with sediment and erosion control measures that meet Design Standards in Sensitive Watersheds [15A NCAC 413 0124] However due to the size of the project NC DOT shall not be required to meet 15A NCAC 4B 0124(a) regarding the maximum amount of uncovered acres Mooresville Regional Office Location 610 East Center Ave Suite 301 Mooresville NC 28115 Phone (704) 663 16991 Fax (704) 663 -60401 Customer Service 1- 877 -623 6748

nprap above the normal high water mark shall be minimized Any nprap placed for stream stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage 3 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 4 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 5 Bridge deck drains shall not discharge directly into the stream 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 6 Bridge piles and bents shall be constructed using driven piles (hammer or vibratory) or dulled shaft construction methods More specifically betting or other methods of pile driving are prohibited without prior written approval from NCDWQ first 7 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 8 All pile driving or drilling activities shall be enclosed in turbidity curtains unless otherwise approved by NCDWQ in this certification 9 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 10 The dimension pattern and profile of the stream above and below the crossing shall not be modified Disturbed fioodplains and streams shall be restored to natural geomorphic conditions 11 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 12 During the construction of the project no staging of equipment of any kind is permitted in waters of the U S or protected riparian buffers 13 Heavy equipment shall be operated from the banks rather than in the stream channel in order minimize sedimentation and reduce the introduction of other pollutants into the stream 14 No rock sand or other materials shall be dredged from the stream channel except where authorized by this certification 15 Temporary dewatenng sites must be restored to pre existing conditions unless more natural geomorphic conditions can be provided Dr Gregory J Thorpe Page Three 16 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 the 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 17 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 18 All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3 1 unless otherwise authorized by this certification 19 Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited 20 A copy of this Water Quality Certification shall be posted 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 21 Native riparian vegetation must be re established within the construction limits of the project by the end of the growing season following completion of construction 22 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 30 days after the Division of Land Resources has released the project 23 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
