The project begins 1.2 miles east of Cashiers and extends east for 2500 feet. The work is necessary to improve safety and reduce congestion associated with the current two-lane US highway east of Cashiers. This project is part of the Transportation Improvement Program. I am enclosing a PCN, astraight-line diagram with the proposed erosion control and construction limits along this project. In addition, I am sending a typical section of the road, cross sections, drawings for pipe culvert replacements, as well as a marked county and USGS -' quad map. _. The North Carolina Natural Heritage Database was checked for records of threatened and endangered species. There are no records for threatened or endangered species within the watershed of the unnamed tributary of the Horsepasture River. Additionally, there are no ',~ records of threatened and endangered species between the confluence of the unnamed tributary with Horsepasture River and Sapphire Lake. The unnamed tributary originates within a few feet of the culvert inlet and does not have sufficient flow to support fish or mussels. The impacts from this culvert extension will be minimal. For these reasons, there --1 will be "no effect" on threatened or endangered species. z :~ U a Page 2 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 sedimentation control measures during installation to ensure sedimentation is being effectively controlled. If the planned devices are not functioning as intended, they will be replaced immediately with better devices. The sedimentation control devices will be in place prior to pipe culvert removal and will remain in place until the new pipes are in place. Impacts to Waters of the United States The unnamed tributary appears to be a spring seep, which originates less than 20 feet above the culvert outlet. The stream is not shown on the USGS topographic map. Although the flow is minimal, it appears to be perennial. The seep does not have awell-defined channel; however, there is a channel that lacks vegetation at the culvert outlet. Substrate is cobble, gravel and sand below the pipe. For these reasons, we believe that the stream is under the jurisdiction of the U.S. Army Corps of Engineers. In order to extend the culvert, it will be necessary to impact waters of the United States in the Savannah River Basin. Specifically, NCDOT is requesting to extend one metal culvert in an unnamed tributary to the Horsepasture River. (DWQ Class: C Tr,). Riprap stabilization is shown in the attached diagram. However, if necessary, this riprap placement will be up slope of the stream origin. Listed below is a summary of the proposed impacts.

Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. The culvert is being extended the minimum amount necessar~g_ain the necessary width to build the climbing lane There is no way to add the necessarylane and avoid the impact. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that maybe appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. Page 5 of 8 An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability and to request written approval of mitigation prior to submittal of a PCN. For additional information regarding the application process for the NCEEP, check the NCEEP website at http:/hvww.nceep.net. If use of the NCEEP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): 20 Amount of buffer mitigation requested (square feet): N/A Amount of Riparian wetland mitigation requested (acres): N/A Amount ofNon-riparian wetland mitigation requested (acres): N/A Amount of Coastal wetland mitigation requested (acres): N/A IX.

Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate.
