S. Army Corps of Engineers 151 Patton Avenue, Room 208 Asheville, NC 28801-2714 Subject: Nationwide 33 Permit Application Temporary Diversion – Roadway Slide (Hwy. 28 North) in UT to Powell Branch Graham County, North Carolina State Project No. 51214.01Y Dear Ms. Beckwith: The North Carolina Department of Transportation (NCDOT) has temporary placed UT of Powell Branch into a diversion pipe under Hwy. 28 North. A landslide has occurred blocking Hwy. 28 North and has blocked the existing CMP pipe and channel of the UT along Hwy. 28 North. The HDPE diversion pipe is 24” in diameter and 180’ in length. The diversion work has been completed due to the emergency nature of the landslide. Once the landslide has been moved to waste areas and the slope has been stabilized, the UT will be placed back into the pre-existing channel and the drainage CMP under Hwy. 28 North. Once UT is placed back into natural channel feature, the CMP under Hwy. 28 North will be embedded partly below the natural stream grade to promote bedload retention and aquatic life passage, though the stream do not appear large enough to support fish (none seen on site visit). The road will be closed until landslide site is safe for travel. We request verification of the permit since the project does not qualify for non- notification. Enclosed are a PCN application, preliminary jurisdiction form, a USGS quad map, photographs, and other pertinent project information to assist in your review. In Graham County, Carolina northern flying squirrel (Glaucomys sabrinus coloratus), Gray bat (Myotis grisescens), Indiana Bat (Myotis sodalis), Northern long-eared bat (Myotis septentrionalis), Appalachian elktoe (Alasmidonta raveneliana), Spotfin chub (Erimonax monachus), Rusty patched bumble bee (Bombus affinis), Virginia spiraea (Spiraea virginiana) and Rock gnome lichen (Gymnoderma lineare) are known from current records (or suspected to occur) and are federally-listed as either threatened or endangered. Hwy. 28 North Page 2 January 17, 2018 The stream diversion work will occur in existing right of way. Tree removal, percussive activities, jackhammering and mechanized pile driving may be required to stabilize land slide area. The project area is not in a “red HUC” for NLEB. The existing culvert is much too small to be used for bat roosts. Therefore, this project should have “no effect” on gray bats, Indiana bats, or NLEB. The Carolina northern flying squirrel are rock gnome lichen are found in spruce-fir forests and other isolated high elevation locations in western North Carolina. However, rock gnome lichen is an exception because it can occasionally be found at lower elevations in deep river gorges with high humidity or on some vertical rock faces that are periodically wet. The project area is much too low in elevation for these species and there are no damp rock faces nearby. Stringent erosion and sedimentation control measures will be used to minimize adverse effects of the work on aquatic habitats due to proximity to Powell Branch. Habitats for other listed species appear lacking at the project sites and none of the species known from Graham County were observed during field visit. The work should not have any effect on cultural resources since most of the work occurs within existing disturbed right of way. The U.S. Forest Service has determined that work outside of NCDOT right-of-way (landslide cleanup/stabilization) will be an “exempt undertaking” due to negative surveys and steep slopes. Impacts to Waters of the United States The UT to Powell Branch (DWQ Class: WS IV: CA) that has been impacted is shown on the North Carolina Division of Water Resources map as a perennial stream. The stream at the site has a well-defined channel approximately 1 feet in width with substrates of bedrock, gravel, and silt, therefore, we believe this unnamed tributary is a Relatively Permanent Water and under the jurisdiction of the U.S. Army Corps of Engineers. In order to complete this emergency project, it will be necessary to impact waters of the United States in the Little Tennessee River Basin (CU 06010202). Listed below is a summary of the proposed impacts: Site No. Existing Condition Proposed Condition Net Impacts (feet) 1 UT of Powell Branch Temporary Flow Diversion Pipe 180 Hwy. 28 North Page 3 January 17, 2018 Permits Requested NCDOT is hereby requesting authorization under Section 404 of the Clean Water Act to proceed with the construction project outlined above. By copy of this letter, I am asking Mrs. Marla Chambers, Western NCDOT Review Coordinator of the North Carolina Wildlife Resources Commission (NCWRC), to comment directly to you and I concerning the 404 Nationwide Permit request. This application has been sent to the North Carolina Department of Environmental Quality (DEQ), Division of Water Resources (DWR) for a written certification. Please contact me at (828) 631-1145 if you have any questions about this application or need additional information. Your prompt review and consideration of this request will be greatly appreciated.
