CONTI, JR. RETARY 11®29. Subject: Nationwide Permit #14 SR 1591, Eastbrook Circle State Project No. 13C.012139 (DWQ Minor Permit Fee $240) Rutherford County, NC Dear Ms. Beckwith: I have enclosed a straight-line diagram with erosion control plan, a PCN application for NWP 914, and a vicinity map relative to the proposed secondary road project on SR 1591 Eastbrook Circle, Burke County, NC. We propose to replace a wooden/steel bridge with an 81" x 59" aluminum pipe culvert on an UT to Hunting Creek. Total permanent stream impact will be 50 feet. A temporary impervious dike will be used for dewatering during installation and removal. The UT is approximately 5 feet wide with primarily bedrock substrate. Existing channel morphology will be maintained upstream and downstream of the culvert. The culvert will be placed below existing streambed elevation whenever possible. Bedrock may prohibit burial of the culvert invert at this location. Riparian vegetation will be reestablished along disturbed areas associated with the culvert extensions. Stormwater will be diverted through grass-lined ditches or vegetated buffers prior to entering streams. No effect on federally listed species (threatened or endangered) or their habitats is anticipated. As a part of the 401 Certification process, a copy of the application will be forwarded to the NC State Historic Preservation Office as required by Section 106 of the National Historic Preservation Act of 1966 and GS 121-12(a). Division Thirteen Office Post Office Box 3279 Asheville, NC 28802 Phone: 828/251-6171 Office of the Division Engineer Fax: 828/251-6709 www.ncdot.gov/doh/operations/divisionl3 Ms. Lori Beckwith Page -2 SR 1591, Burke County Marc 25, 2011 By copy of this letter, we request Ron Linville, North Carolina Wildlife Resources Commission Coordinator, to comment directly to the Corps concerning the permit request. By copy of this letter, we are asking Ed Ingle, Area Roadside Field Operations Engineer, to comment on the above project. The UT to Hunting Creek is classified WS-IV. A trout buffer variance will not be required for the project. By copy of this letter, I am forwarding four (4) copies of the application package to Brian Wrenn, NC Division of Water Quality, 401/Wetland Unit and an additional copy to Mike Parker, NC DWQ Asheville Regional Office for review and comment. Please charge the application fee of $240.00 to WBS element # 13C.012139. Please forward comments directly to the Corps with copy to Division 13 Environmental Officer. Your earliest consideration for this request would be greatly appreciated. If you have any questions or information needs, please contact me at (828) 251-6171. Sincerely, 04r, Roger D.

Temporary stone ditch checks shall be installed as soon as ditch line is established. Pipe outlet and inlet protection will be done as soon as the pipe is installed. Seeding and other permanent erosion control measures are to be implemented as soon as practical. Temporary rock silt checks (type B) will be spaced as required by percent of grade as described on page VI-16 in the Erosion And Sedimentation Guidelines. No. 5 stone, or equivalent, will be used in conjunction with temporary rock silt check Type-B in locations where water is leaving the project or entering a pipe. For silt basin size see attached plans. Basins are to be cleaned out when half full. Per permit conditions for Corps of Engineers and the Wildlife Resources Commission, all pipes in streams 48" or greater must be buried 12" below _ streambed elevation. Pipes less than 48" must be buried with 20% of the diameter below streambed elevation. Sheet 5 of 9 PIPE INSTALLATION NOTES 1) Install erosion control devices. Pipe to be placed in the dry. 2) Remove material and existing pipe while limiting, as much as possible, material and sediment from entering the stream and/or escaping from project. 3) Prepare pipe foundation while again taking care to limit, as much as possible material and sediment from entering the stream and/or escaping from project. Where possible, new grade will be below existing streambed. 4) Place the new pipe and compact backfill. 5) Install slope protection on outlet and inlet ends of pipe. Also complete installation of erosion control measures and perform maintenance as needed on existing measures. 6) Establish permanent vegetation as soon as possible.
