EASLEY GOVERNOR June 25, 2007 Mr. David Baker, NCDOT Regulatory Project Manager U.S. Army Corps of Engineers 151 Patton Avenue, Room 208 Asheville, NC 28801-2714 Subject: Nationwide 14 & NW 33 Permit Application Action ID. SAW-2006-40904-387 Revised SR 1197 -Camp Branch Road LYNDO TIPPETT SECRETARY Swain County State Project No. 140.087014 (DWQ Minor Permit Fee $200) Dear Mr. Baker: During a recent evaluation of the above road an improvement in the alignment was made to make a property owners' driveway safer. Originally we had planned on a 10' extension at site #2, a 45' extension at site 3 and a 185' stream location. With the new alignment we will be extending site #2 40', site #3 30' and we will be constructing approximately 40' of new channel before turning the stream in an existing old channel bed. The Natural Heritage Database was checked for records of federally threatened and endangered species. There are no records of threatened or endangered species for Camp Branch or Conley Creek. Additionally, there are no records for the entire Conley Creek watershed. There are records for the Appalachian elktoe (Alasmidonta raveneliana) in the Tuckasegee River near the confluence with Conley Creek. However, this location is approximately five miles from the nearest culvert extension. The impacts from the culvert replacements and channel relocation should be minimal. For these reasons, we believe there will be "no effect" on threatened and endangered species. Impacts to historic or cultural resources are not anticipated. If the State Historic Preservation Office (SHPO) and the Office of State Archaeology determines that further investigations are required, NCDOT will conduct the appropriate site investigations and obtain compliance from SHPO prior to project construction. The best management practices will be used to minimize and control sedimentation and erosion on this project. The construction foreman will review all erosion control measures daily to ensure sedimentation and erosion is being effectively controlled. If the planned devices are not functioning as intended, they will be immediately replaced with better devices. The rock silt screens and other erosion control devices will be in place prior to pipe culvert construction and will remain in place until the project is stabilized. Impacts to Waters of the United States Camp Branch and Conley Creek are shown on the USGS topographic maps as perennial streams. These streams have sufficient flow to support fish. The streams have well defined channels with substrate of cobble, gravel and sand. The stream channels lack vegetation. For these reasons, we believe the streams are under the jurisdiction of the U.S. Army Corps of Engineers. In order to construct the project in accordance with our current secondary road standards, it will be necessary to impact waters of the United States in the Little Tennessee River Basin. Specifically, NCDOT is requesting to extend/replace three metal culverts and relocate a section of stream in Camp Branch (DWQ Class C) and place headwalls on an existing culvert in Connelly Creek (DWQ Class C, Tr). Listed below is a summary of the proposed impacts.

By copy of this letter, I am asking Mr. David McHenry, Mountain Region Coordinator, of the North Carolina Wildlife Resources Commission (NCWRC) to comment directly to you concerning the 404 Nationwide Permit request. Also, by copy of this letter, I am requesting authorization under Section 401 of the Clean Water Act from the North Carolina Department of Environment and Natural Resources (DENR), Division of Water Quality (DWQ). In addition, I am requesting Mr. McHenry and Mr. Ed Ingle, Roadside Environmental Field Operations Engineer (NCDOT), to comment directly to me concerning this permit request. If you have any questions or need additional information, please contact me at (828) 488-2131. Your early review and consideration will be greatly appreciated. Si ely, J nathan L. Woo a d,- P.E.
