The project shall be constructed in accordance with your application dated received January 12 2012 After reviewing your application we have decided that these impacts are covered by General Water Quality Certification Numbers 3689 and 3820 This certification corresponds to the Nationwide Permits 13 and 14 issued by the Corps of Engineers This approval is also valid for the Neuse Riparian Buffer Rules (15A NCAC 2B 02 -13) 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 This approval will expire with the accompanying 404 permit 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 NCDWQ 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 the conditions If total wetland fills for this project (now or in the future) exceed one acre or of 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) Additional buffer impacts may require compensatory mitigation as described in 15A NCAC 2B 0242(9) For this approval to remain valid you must adhere to the conditions listed in the attached certifications and any additional conditions listed below Conditions of Certification 1 Stream channel restorations shall be completed and stabilized prior to diverting water into the new channel Stream banks shall be matted with coir 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 2 Unless otherwise approved in this certification placement of culverts and other structures in open waters and streams shall be placed below the elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches and 20 percent of the culvert diameter for culverts having a diameter less than 48 inches to allow low flow passage of water and aquatic life Design and placement of culverts and other structures including temporary erosion control measures shall not be conducted in a manner that may result in dis equilibrium of wetlands or streambeds or banks adjacent to or upstream and down stream of the above structures The applicant is required to provide evidence that the equilibrium is being maintained if requested in writing by NCDWQ if this condition is unable to be met due to bedrock or other limiting features encountered during construction please contact NCDWQ for guidance on how to proceed and to determine whether or not a permit modification will be required 3 If multiple pipes or barrels are required they shall be designed to mimic natural stream cross section as closely as possible including pipes or barrels at flood plain elevation and /or sills where appropriate Widening the stream channel should be avoided Stream channel widening at the inlet or outlet end of structures typically decreases water velocity causing sediment deposition that requires increased maintenance and disrupts aquatic life passage 4 Riprap 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 5 For all streams being impacted due to site dewatermg activities the site shall be graded to its preconstruction contours and revegetated with appropriate native species 6 All riparian buffers impacted by the placement of temporary fill or clearing activities shall be restored to the preconstruction contours and revegetated Maintained buffers shall be permanently revegetated with non woody species by the end of the growing season following completion of construction For the purpose of this condition maintained buffer areas are defined as areas within the transportation corridor that will be subject to regular NCDOT maintenance activities including mowing The area with non maintained buffers shall be permanently revegetated with native woody species before the next growing season following completion of construction 7 Pursuant to 15A NCAC 213 02.)3(6) sediment and erosion control devices shall not be placed in Zone 1 of any Neuse Buffer without prior approval by NCDWQ At this time NCDWQ has approved no sediment and erosion control devices in Zone I outside of the approved project impacts anywhere on this project Moreover sediment and erosion control devices shall be allowed in Zone 2 of the buffers provided that Zone 1 is not compromised and that discharge is released as diffuse flow 8 All stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities unless otherwise approved by this certification 9 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 10 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 11 The dimension pattern and profile of the stream above and below the crossing shall not be modified Disturbed floodplains and streams shall be restored to natural geomorphic conditions 12 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 13 The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings submitted for approval 14 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 15 Heavy equipment shall be operated from the banks rather than in the stream channel 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 17 No rock sand or other materials shall be dredged from the stream channel except where authorized by this certification 18 Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited 19 The permittee and its authorized agents shall conduct its activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with §303(d) of the Clean Water Act) and any other appropriate requirements of State and Federal law If NCDWQ determines that such standards or laws are not being met (including the failure to sustain a designated or achieved use) or that State or federal law is being violated or that further conditions are necessary to assure compliance NCDWQ may reevaluate and modify this certification 20 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 En,meer and the on site project manager 21 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 22 The issuance of this certification does not exempt the Permittee from 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 23 The Permittee shall report any violations of this certification to the Division of Water Quality within 24 hours of discovery 24 Upon completion of the project (including any impacts at associated borrow or waste sites) the NCDOT Division Engineer shall complete and return the enclosed Certification of Completion Form to notify NCDWQ when all work included in the 401 Certification has been completed 25 Native riparian vegetation (► e trees and shrubs native to your geographic region) must be reestablished in the riparian areas within the construction limits of the project by the end of the growing season following completion of construction 26 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 27 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 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 28 Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this Certification If you wish to contest any statement in the attached
