The project shall be constructed in accordance with your application dated received June 29, 2011 with additional information dated received July 29, 2011. After reviewing your application, we have decided that these impacts are covered by General Water Quality Certification Number 3820. This certification corresponds to the Nationwide 14 issued by the Corps of Engineers. This approval is also valid for the Jordan Riparian Buffer Rules (!SA NCAC 2B North Carolina Division of Water Quality, Winston-Salem Regional Office Location: 585 Waughtown St Winston-Salem, North Carolina 27107 `~ ~ne ~~?~~ ~ ~ ~: Phone: 3's6-711-50 00 1 FAX:336-771-46301 Customer Service: l-877-623.6748 NOI'(~'1C1POhria Internet: www.ncwaterquality.org ~~~`l~r~~/, ,,' An Equal Opportunity!

In addition, you should acquire any other federal, state or local permits before you proceed with your project g 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 maybe required as described in 15A NCAC 2H .0506 (h) (6) and (7). Additional buffer impacts may require compensatory mitigation as described in 16A NCAC .0268. For this approval to remain valid, you must adhere to the conditions listed in the attached certification(s) and any additional conditions listed below. Condition(s) of Certification: Project Specific Conditions 1. 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. Overflow pipes maybe laid at grade. 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. 2. A floodplain bench shall be installed at the inlet of the overflow pipe. The bench shall be comprised of large rock. The floodplain bench shall also be tapered to tie into the upstream sireambank. Further, if the stream channel at the outlet of the overflow pipe overwidens, then the Division of Water Quality shall be consulted for appropriate restoration measures. 3. All stotmwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities, unless otherwise approved by this certification. 4. 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. 5. Pursuant to I SA NCAC 2B .0267, sediment and erosion control devices shall not be placed in Zone 1 of any Iordan Buffer without prior approval by NCD WQ. At this time, NCDWQ has approved no sediment and erosion control devices in Zone 1, 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 I is not compromised and that discharge is released as diffuse flow. General Conditions 6. For the 20 lineaz feet of streams being impacted due to site dewatering activities, the site shall be graded to its preconstruction contours and revegetated with appropriate native species. 7. 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. 8. 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. 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. ] 0. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings submitted for approval. 1 I. 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. 12. 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. 13. 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 azeas within the fencing are prohibited unless otherwise authorized by this certification. 14. The issuance of this certification does not exempt the Permittee from complying with any and all statutes, rules, regulations, or ordinances that maybe imposed by other government agencies (i.e. local, state, and federal) havingjurisdiction, including but not limited to applicable buffer rules, stormwater management rules, soil erosion and sedimentation control requirements, etc. 15. The Permittee shall report any violations of this certification to the Division of Water Quality within 24 hours of discovery. 16. All mechanized_equipment operated neaz 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. If you wish to contest any statement in the attached Certification you must file a petition for an administrative hearing. You may obtain the petition form from the office of Administrative hearings.
