NC Ecosystem Enhancement Program Attn: Jeff Jurek DWQ Project # 20120916 February 8, 2013 Page 3 of 7 4. Work in the Dry 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 ( hqp:// www.ncdot.org/doh/operationsBMP manual/downloadBMP Manual.pdo such as sandbags, rock berms, cofferdams and other diversion structures shall be used to prevent excavation in flowing water. 5. Culverts Culverts required for this project shall be installed in such a manner that the original stream profiles are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and longitudinal profile) must be maintained above and below locations of each culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re- established or, if the pipes are installed in a perched manner, the pipes shall be removed and re- installed correctly. All authorized culverts and other structures in waters, streams, and wetlands must 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 downstream of the above structures. The applicant is required to provide evidence that the equilibrium shall be maintained if requested in writing by DWQ. Culverts shall be placed so that the opening(s) match the natural stream channel wherever possible. Bank -full flows (or less) shall be accommodated through maintenance of the existing bank -full channel. Additional culverts shall be allowed only to receive flows exceeding bank -full. The low flow pipes should be aligned with the deepest part of the stream channel, so that flow is maintained during low flow conditions. Field adjustments of the culvert placements may be necessary to correctly install the culverts. See also the DOT manual at above mentioned website for culvert installation. The establishment of native, woody vegetation and other soft stream bank stabilization techniques must be used where practicable instead of rip rap or other bank hardening methods. If rip -rap is necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of Water Quality. All approved rip -rap shall be appropriately keyed in and only placed in wetland and stream areas that have permitted impacts. 6. Any final construction plans for this project must include or reference the application and plans approved by the DWQ under this authorization letter and certification. 7. All mechanized equipment will be regularly inspected and maintained to prevent contamination of waters and wetlands from hydrocarbons or other potential toxic chemicals. In the event of a hydrocarbon or chemical spill, the permitee /contractor shall immediately contact the Division of Water Quality, between the hours of 8 am to 5 pm at the Wilmington regional office at 910.796.7215 or Steve Lewis at 919.807.6308 and after hours and on weekends call the USCG National Response NC Ecosystem Enhancement Program Attn: Jeff Jurek DWQ Project # 20120916 February 8, 2013 Page 4 of 7 8. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the 404 /401Permit Application. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed by NC Ecosystem Enhancement Program (EEP) and its authorized agents /contractors so that no violations of state water quality standards, statutes, or rules occur. Any violations of this condition including turbidity and failed silt fences MUST be reported to the Wilmington Regional Office immediately at 910.796.7215. The Division suggests that the construction plans contain notes requiring the contractor to side cast the material from the trenching from the silt fence installation onto high ground or onto the permitted wetland impact side to avoid unpermitted wetland impacts. 9. 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 two months of the date that the Division of Land Resources has released the project; 10. Construction Stormwater Permit NCGO10000 Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an NPDES General stormwater permit (NCGO10000) administered by DWQ is automatically issued to the project. This General Permit allows stormwater to be discharged during land disturbing construction activities as stipulated by conditions in the permit. If your project is covered by this permit [applicable to construction projects that disturb one (1) or more acres], full compliance with permit conditions including the sedimentation control plan, self - monitoring, record keeping and reporting requirements are required. A copy of this permit and monitoring report forms may be found at http-//h2o enr state.nc. us/su/Forms Documents. htm. Please contact this Office prior to construction for an on -site meeting with a representative of the Division to explain this general permit and the Division's expectations. 11. Pre - Construction Notification The permitee shall notify the Division in writing via e-mail or phone within two weeks prior to the beginning of the work authorized under this certification. A pre - construction meeting may be required with the Division prior to the start of these phases if the Division has any concerns about the project's compliance. 12. Continuing Compliance: The NC Ecosystem Enhancement Program and its authorized agents /contractors shall conduct its activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with section 303(d) of the Clean Water Act) and any other appropriate requirements of State law and federal law. NC Ecosystem Enhancement Program shall require its contractors (and /or agents) to comply with all of the terms of this Certification, and shall provide each of its contractors (and/or agents) a copy of this Certification. A copy of this Certification and associated permit drawings shall be included in the construction NC Ecosystem Enhancement Program Attn: Jeff Jurek DWQ Project # 20120916 February 8, 2013 Page 5 of 7 contract and available on the job site at all times. If the Division 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, the Division may reevaluate and modify this certification to include conditions appropriate to assure compliance with such standards and requirements in accordance with 15A NCAC 2H.0507(d). Before modifying the certification, the Division shall notify NC Ecosystem Enhancement Program and the US Army Corps of Engineers, provide public notice in accordance with 15A NCAC 21-1.0503 and provide opportunity for public hearing in accordance with 15A NCAC 21-1.0504. Any new or revised conditions shall be provided to NC Ecosystem Enhancement Program in writing, shall be provided to the United States Army Corps of Engineers for reference in any permit issued pursuant to Section 404 of the Clean Water Act, and shall also become conditions of the 404 Permit for the project. 13. Protective Fencing The wetland or water boundaries within 50 feet of the construction corridor(s) of the project boundaries approved under this authorization shall be clearly marked with orange warning fencing (or similar high visibility material). These boundaries shall be identified as depicted on the jurisdictional determination map signed by the US Army Corps of Engineers prior to any land disturbing activities. These wetland boundary identifications (flagging, fencing, etc.) must be maintained on the property until the construction phase is completed. 14. Turbidity Standard The turbidity standard of 50 NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 2B..0211. Appropriate sediment and erosion control practices must be used to meet this standard. Any violations to the turbidity standard need to be reported to the Wilmington Regional Office at 910.796.7215. 15. Sensitive Watershed Erosion and Sediment Control Practices The UTs to Mill Swamp are classified by the NC Division of Water Quality as C; NSW, qualifying them as a sensitive watershed. Sediment and erosion control measures shall adhere to the design standards for sensitive watersheds [15A NCAC 4B .0124] throughout the life of this project. See NCDOT publication, Best Management Practices for the Protection of Surface Waters (March 1997). 16.
