Hanes Mill Rd, Ste. 103 Winston-Salem, NC 27107 Sabject: Nationwide 14 Permit Application and Jordan Lake Riparian Buffer Authorization for the replacement of Bridge No. 270 on SR 1552 (Barber Road) over UT to Travis Creek, Alamance CounCy, North Carolina, WBS Element No. 17BP.7.R.63 Dear Mr. Bailey and Mr. Wrenn: The North Carolina Department of Transportation (NCDOT) is proposing to replace a fimctionally obsolete 18' x LO' two span timber bridge with a new 20' x 4' aluminmum box culvert with concrete footing keyed into bedrock. An aff-site detour will be used to convey traffic during construction. The project will also include minor approach work on the existing roadway. Please find enclosed a PCN application, Stonnwater Management Plan, Culver[ Survey & Hydraulic Design Report, permit dra�vings, buffer drawings, Erosion Control Plan, a USGS quad map, SHPO Concurrence Forms, and photographs. The North Carolina Natural Heritage Database was checked for records of threatened and endangered species. The database lists no species for Alamance County that have federal status. The Bald eagle is protected in every county in North Carolina under the Bald and Golden Eagle Protection Act. No suitable feeding/water source is located within one mile of the project study area to support Bald eagle habitat, including the 660-foot radius fi om the edge of the study area. Since there was no foraging habitat within the review area, a survey of the project study area wiYhin 660 feet of the project limits was not conducted. Mr. Gary Jordan (USFWS) recently released the Programmatic Conference Opinion (PCO) for the recently listed Northern Long- eared Bat (NLEB). This opinion states, in part, that "... it is the Servlce's conJerence opinion that NCDOT activities in eastern North Carolina (Division 1-8), as proposed, are nat Ilkely to jeopardize the continued existence of the NLEB. " This project was reviewed by NCDOT's Human Environment Unit in 2012 for potential affects to historical architecture and archaeology. It was determined that no survey was required for historical architecture. A suivey was conducted for archaeology ou August 24, 2012, and it was determined there would be no eligible archaeological resources present within the project study area. �Nothing Compares� Slafe of NoMh Cumlina I Depnnmem ofTra�sporta[iav I Division of Highways, Division 7 OtPice 1584 Yanceyville S�reel, Greensboro, NC27405I P� O.

Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The proposed project is to remove and replace a structurally deficient bridge and replace it with a bottomless culvert. Roadway approach work is minimized as much as is practical to reduce the overall project footprint. Impacts to the associated protected riparian buffers have also been reduced by promoting sheet flow as well as providing grass shoulders to promote infiltration. An off-site detour will be employed to avoid the need for a temporary parallel structure. Bank stabilization will be minimized to those areas where deemed necessary. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Erosion and sedimentation BMPs will be installed prior to construction. Water will be diverted around the work area to prevent sedimentation of downstream aquatic resources. Impacts will be minimized by strict enforcement of Best Management Practices for the protection of surFace waters, restrictions against the staging of equipment in or adjacent to waters of the US and coordination (including a pre-construction meeting) with the Division Environmental Supervisor.

Is this an after-the-fact permit application? ❑ Yes � No 2c. If you answered "yes" to one or both of the above questions, provide an explanation of the violation(s): 3. Cumulative Impacts (DWQ Requirement) 3a. Will this project (based on past and reasonably anticipated future impacts) result in � Yes � No additional development, which could impact nearby downstream water quality? 3b. If you answered "yes" to the above, submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent DWQ policy. If you answered "no," provide a short narrative description. Per the NC DWQ April 10, 2004 Version 2.1 Cumulative Impacts policy, small scale public transportation projects — such as widening projects, bridge replacements and intersection improvements — have a"low potential for cumulative impact since little (if any) new impervious surface is added and the projects are usually in already developed locales." This proposed project is within a somewhat developed landscape (i.e. existing residential homes in the vicinity), this is not a road on a new location (i.e. there is an existing road and bridge structure and thus, the area already contains impervious surfaces) and the project drains to a UT to Travis Creek, which is Class WS-V; Nutrient Sensitive Waters (NSW); and impaired due to a Fair Bioclassification (i.e. not HWQ or ORW). We anticipate the NC DWR will advise us if a qualitative or quantitative analysis is needed. 4. Sewage Disposal (DWQ Requirement) 4a. Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. It is not anticipated that this project will generate any wastewater as it is a roadway project. Page 10 of 11 PCN Form — Version 1.3 December 10, 2008 Version 5. Endangered Species and Designated Critical Habitat (Corps Requirement) 5a. Will this project occur in or near an area with federally protected species or � Yes � No habitat? 5b.
