SHCRI.I'ARY Subject: Nationwide 14 Permit Reauthorization Action ID Nos. SAW-2006-40132-356 and SAW-2007-1082-356 DWQ Project No. 061 175 and DWQ Project No. 070487 SR 1521-B & C, Onion Mountain Road Macon County State Project No. 14C.056107 (DWQ Minor Permit Fee $240) Dear Ms. Beckwith: The North Carolina Department of Transportation (NCDOT) was issued previously a permit (SAW- 2007-1082-356) for construction of Sections B and C of SR 1521, Onion Mountain Road, in Macon County. Prior to the issuance of this permit for the road construction project, we were issued a permit (SAW-2006-40132-356) to install a 60-foot section of culvert and relocate 32 feet of channel at a site where the stream flowed.across Onion Mountain Road. The U.S. Postal Service had requested (hat we eliminate the stream from flowing across the road to facilitate mail delivery. Approximately 47 feet of this culvert was installed on Onion Mountain Road under permit SAW- 2006-40132-356. A 20-foot section was installed under the roadway and 27 feet was installed temporarily along a driveway; however, the channel change was not made at the time due to the pending construction and realignment of the road. When this section of the road is constructed, the pipe along the driveway will be removed and the pipe under the road will be re-installed and extended to 60 feet. The construction project was started and a portion of the road was completed, but work was not completed at twojurisdictional sites: The project had to be stopped due to a lack of funding and the permits expired in June 2009 and March 2007 respectively. Funds are now available to complete the previously permitted project. We are requesting reauthorization to complete this work. As per our phone conversation, f am submitting a new PCN, diagrams of the implct sites, a marked vicinity map, USGS topographic map showing sites 4 and 7, USGS topographic map showing all of Eriiorcendl t' z'c Ppgne (82HJ586?2/41,_ ,,,' , 253,NeLsru Rrual:Syhu Nnrtp;CiuoGnn 2N779; „z„ ,,,,'_Fqu (82A/'SN6`404 SR, 1521 B & C, Onion Mt. Road 2 t the originally permitted sites and photographs for sites 4 and 7. We propose to install new culverts slightly below the existing streambed elevations where bedrock is not encountered to minimize impacts to aquatic habitats and allow the existing stream gradients to remain as unchanged as Y physically possible. Additionally, at site 4 the short section (38 feet) of stream that parallels the existing road will need to be relocated to facilitate changing the road alignment. The North Carolina Natural Heritage Database was checked for records of federally endangered or . threatened species. There are no records of endangered or threatened species listed for the streams to be impacted. Additionally, there are.no records for the Ellijay Creek watershed. The.Little Tennessee River is designated critical habitat for the spolfin chub (Erionronax monacbn) and Appalachian elktoe (Alasmidonlet rhveneliana); however, there are no records in the database for the spotfin chub or Appalachian elktoe upstream of Lake Emory. This project is approximately 10 miles from the Little Tennessee River. Direct. impacts from culvert replacement in the small tributaries should not be significant. For these reasons, we believe therenvill be "no effect" on threatened and endangered species. This project was reviewed previously for cultural resources. It was determined that there were no historical properties or archaeological sites that were eligible for listing on the National Register. 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 controlled effectively. If the planned devices are not functioning as intended, they will be replaced immediately 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 The streams to be impacted for this.project are small and have limited flow. The streams appear to be perennial and have substrates composed primarily of gravel, sand or silt. The unnamed tributary at site 4 is not shown on the USES 'topographic map. This stream flows approximately.1000 feet to an unnamed tributary to Laurel Creek that is shown on the USGS topographic map as perennial. This stream then flows approximately 1600 feet to Laurel Creek. The unnamed tributary at site 7 is shown on the USGS topographic map as perennial; it flows approximately 200 feet downstream where it meets the same unnamed tributary that site 4 flows into. This unnamed tributary flows approximately 4500 feet to Laurel Creek. Laurel Creek then flows approximately one mile to Ellijay Creek. Ellijay Creek then flows approximately 3.5 miles to the Cullasaja River. The Cullasaja River meets the definition of a Traditional Navigable Water. For these reasons, we believe these small unnamed tributaries are Relative Permanent Waters that are under the jurisdiction of the U.S. Army Corps of Engineers. In order to complete construction of this 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, a charnel needs to be relocated, one section of culvert removed and a remaining section of culvert installed at site 4. A culvert steeds to be replaced and extended at site 7. The culverts at sites 1-3 and 5-6. that were permitted previously have been installed. The impacts are listed in the table below. SR 1521 B & C, Onion Mt.

A permit (SAW 2006-40132-356 and DWQ Project No. 061175) was Issued on August 1, 2006 for 60 foot of pipe and to relocate 32 feet of stream channel. Thr US Postal Service requested a repair where the stream was running across the roadway. Approximately, 47 feet of pipe was Installed, 20 feet under Onion Mountain Road and 27 feet as a temporary measure along an adjacent driveway. The channel was not relocated. Subsequently, we were issued a permit (SAW- 2007-1082-356 and DWQ Project No. 070487) for construction of Onion Mountain Road Sections B & C. Funds ran out before the construction work was completed. The work at Site 4 where the stream relocation is needed and at site 7 near the end of the project require additional work within jurisdictional areas. 6. Future Project Plans 6a.
