Payne, P.E., Division Engineer NCDOT Division 10 716 West Main Street Albemarle, North Carolina 28001 Dear Mr. Payne: You have our approval, in accordance with the attached conditions and those listed below, to incur 71 linear feet of permanent and 74 linear feet of temporary impacts to three unnamed tributaries of South Fork Crooked Creek in order to replace two cross pipes on SR 1520 (Indian Trail-Fairview Road) in Union County. The project shall be constructed in accordance with your application dated January 9, 2004 (received January 15, 2003). After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Nos. 3366 and 3404 corresponding to the U.S. Army Corps of Engineers Nationwide Permit Numbers 33 and 14. 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 unless otherwise specified in the Water Quality Certification. This approval is only valid for the purpose and design that you described in your application except as modified below. If you change your project, you must notify us in writing, and you may be required to send us 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 stream impacts 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. 1. Construction shall be performed so that no violations of state water quality standards, statutes, or rules occur. ¦ 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 water quality standards. ¦ The erosion and sediment control measures for this project must equal or exceed the proper design, installation, operation and maintenance outlined in the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. These 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 projects included under this Certification. North Carolina Division of Water Quality, 401 Wetlands Certification Unit, 1650 Mail Service Center, Raleigh, NC 27699-1650 (Mailing Address) 2321 Crabtree Blvd., Raleigh, NC 27604-2260 (Location) 919-733-1786 (phone), 919-733-6893 (fax), http://h2o.enr.state.nc.us/ncwetlands/ Mr. Benton Payne, P.E. DWQ 040062 January 16, 2004 • For borrow pit sites, the erosion and sediment control measures must equal or exceed the proper design, installation, operation and maintenance outlined in the most recent version of the North Carolina Surface Mining Manual. ¦ Any reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. 2. 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. NCDOT and its contractors and/or agents shall not excavate, fill, or perform mechanized land clearing at any time in the construction or maintenance of this project within waters and/or wetlands, except as authorized by this Certification, or any modification to this Certification (e.g., no work shall occur outside of the footprint of the plans provided). In addition, there shall be no excavation from or waste disposal into jurisdictional wetlands or waters associated with this Certification without appropriate modification. If this occurs, compensatory mitigation may be required since it is a direct impact from road construction activities, 4. This Certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone except for permitted areas associated with culvert conditions. South Fork Crooked and its unnamed tributaries are on the 303(d) list of impaired waters due to sediment and turbidity from urban runoff and storm sewers. NCDOT shall maximize the use of Best Management Practices with regard to sediment and erosion control during construction. Existing vegetated buffers shall not be mowed in order to utilize it for stormwater sheet flow. Additionally, stormwater runoff shall be treated by the use of grass swales, pre-formed scours holes or other means that are compatible with the project site's topography, prior to reaching the stream. 6. The structures required for this project shall be installed in such a manner that the original stream profiles are not altered (i.e. the depth of the channel must not be reduced by a widening of the streambed). Existing stream dimensions (including the pattern and profile) are to be maintained above and below locations of each pipe. The structure shall be designed and installed to allow for fish and other wildlife movement as well as prevent headcutting of the streams. 7. Riparian vegetation must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certificate of Completion" form to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the NC Division of Water Quality upon completion of the project. Please include photographs upstream and downstream of each structure to document correct installation. If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition that conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing. Mr. Benton Payne, P.E.

Army Corps of Engineers Asheville Regulatory Office n. -J _F Attn: Mr. Steve Lund, MS, PWS 1 151 Patton Avenue, Room 208 Asheville, NC 28801-5006 Subject: Union County, Proposed Replacement of Two Cross Pipes Located on SR 1520 (Indian Trail-Fairview Road). WBS Element No. 35981 (DWQ Minor Permit Fee $200.00) Dear Mr. Lund: The North Carolina Department of Transportation (NCDOT) proposes to replace two existing cross pipes on SR 1520 (Indian Trail-Fairview Road) in Union County. The purpose of this letter is to request authorization from the U. S. Army Corps of Engineers to construct the project under Section 404 Nationwide 14 and 33 permit authorizations. The Department proposes to replace the two existing cross pipes (30" x 45' RCP and 24" x 45' CMP) with (3) 48" x 96' corrugated metal pipe. The purpose of the proposed project is to accommodate increased traffic and stormwater runoff that has resulted from recent commercial development in the area. Traffic will be maintained using an off-site detour. The project area has been reviewed for the presence of listed threatened and endangered species and described in a Minimum Criteria Checklist. There are no wetlands present, although impacts to surface waters will occur. There will be 71 linear feet of permanent stream channel loss and approximately 74 linear feet of temporary impacts associated with this pipe replacement. The crossing is an unnamed tributary to South Fork Crooked Creek, Yadkin River Basin, Hydrologic Unit 03040105. A permit drawing and pre-construction notification form are attached to this letter. The NCDOT anticipates that the permit application will be authorized under Section 404 Nationwide permits 14 and 33. We are also hereby requesting 401 Water Quality Certifications, GC3404 and GC3366, from the Division of Water Quality. We are providing seven copies of this application to the North Carolina Department of Environment and Natural Resources, Division of Water Quality, for their review. 716 West Main Street, Albemarle, NC 28001 • (704) 982-0101 • Fax (704) 982-3146 Thank you for your assistance with this project.
