Habitat Conservation Program, NCWRC SUBJECT: Review of NCDOT's application for Section 404 and 401 permits to replace Bridge No. 102 over Plott Creek on SR ll 73 (Plott Creek Road), Haywood County, North Carolina. The North Carolina Department of Transportation has submitted an application to obtain a Section 404 Perinit from the U.S. Army Corps of Engineers and a 401 Water Quality Certification from the NC Division of Water Resources. Staff biologists with the North Carolina Wildlife Resources Coinmission have reviewed the information provided. These corrunents are provided in accordance with the provisions of the state and federal Environmental Policy Acts (G.S. 113A-lthrough 113-10; 1 NCAC 25 and 42 U.S.C. 4332(2)(c), respectively), the Clean Water Act of 1977 (33 U.S.C. 466 et seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U. S.C. 661-667d), as applicable. The NCDOT proposes to replace Bridge No. 102 over Plott Creek on SR 1173 (Plott Creek Road) with a single-barrel reinforced concrete box culvert, measuring 12' W x 5' H x 89' L, on a 1.54 percent slope using an offsite detour. Permanent stream impacts include 89 linear feet for the culvert and SO lf for riprap bank stabilization. Temporary impacts total 145 If for flow diversion. Rainbow Trout resources are expected, therefore a moratorium prohibiting in-stream work and land disturbance within the 25-foot trout buffer should apply from January 1 to April 15 to protect the egg and fry stages of trout. Sediment and erosion control should adhere to the Design Standards in Sensitive Watersheds. Mailing Address: Habitat Conservation • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 707-0220 • Fax: (919) 707-0028 BRIDGE NO. 102, SR 1173 PAGE 2 MAY 20, 2016 PLOTT CREEK, HAYWOOD CO. NCWRC does not object to the issuance of the Section 404 and 401 permits provided that the following conditions are implemented: In-stream work and land disturbance within the 25-foot wide buffer zone are prohibited during the trout spawning seasons of January 1 through April 15 to protect the egg and fry stages of trout. 2. Sediment and erosion control measures shall adhere to the Design Standards in Sensitive Watersheds and be strictly maintained until project completion. 3. Herbaceous vegetation shall be planted on all bare soil as soon as possible following the completion of permanent or temporary ground disturbing activities to provide appropriate long-term erosion control. 4. Tall fescue and straw mulch shall not be used in riparian areas. We encourage NCDOT to utilize onsite vegetation and materials for bank stabilization when practicable. Erosion control matting shall be used on steep slopes and for establishing permanent vegetation in riparian areas. The matting shall be well anchored with staples or wooden stakes and, whenever possible, include live stakes of native trees. Matting in riparian areas should not contain plastic mesh, which can entangle and trap small animals. 5. Stormwater should be directed to buffer areas or retention basins and should not be routed directly into the waterway. 6. The natural dimension, pattern, and profile of the waterway above and below the crossing should not be modified by widening the channel or changing the depth of the waterway. 7. Removal of vegetation in riparian areas should be minimized. Native trees and shrubs should be planted along the banks, as appropriate to the setting, to reestablish the riparian zone and to provide long-term erosion control. 8. Grading and backfilling should be minimized, and tree and shrub growth should be retained, if possible, to ensure long term availability of shoreline cover for fish and wildlife. 9. Where practicable, riprap placed for bank stabilization should be limited to the banks below the high water mark, and vegetation should be used for stabilization above the high water elevation. 10. If concrete will be used during construction, work must be accomplished so that wet (uncured) concrete does not contact surface waters. This will lessen the chance of altering the water chemistry and causing a fish kill. 11. Discharging hydroseeding mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. BRIDGE NO. 102, SR 1173 PAGE 3 MAY 20, 2016 PLOTT CREEK, HAYWOOD CO. 12. Heavy equipment should be operated from the bank rather than in the channel whenever possible in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the waterway. All mechanized equipment operated near surface waters should be inspected and maintained regularly to prevent contamination of surface waters from fuels, lubricants, hydraulic fluids or other toxic materials.
