The North Carolina Department of Transportation (NCDOT) proposes to stabilize approximately 50 feet of stream bank by grading the bank to a slope of no greater than 2:1 and installing geofabric and rip rap along the bank. This activity will result in temporary impacts to the stream and riparian buffers. The stream is located in the Tar-Pamlico River Basin and discharges into Dickson Branch, which is classified by the Division of Water Quality as C NSW 28-83-3-(1.7). The NCDOT anticipates that the pipe replacement activities will be authorized under Nationwide Permit (NWP) 13 and NWP 33, and temporary losses to the waters will be minimized by the use of sheet pile cofferdams being Post Office Box 3165, Wilson, North Carolina 27895-3165 Phone (252) 6237-6164 Fax (252) 234-6164 placed within the proposed impact area. The sheet pile cofferdams will be removed immediately upon completion of the construction activities. FEDERALLY-PROTECTED SPECIES AND CULTURAL RESOURCES The Fish and Wildlife Service (FWS) currently list two federally protected species for Edgecombe County (Table 1). Table 1-Federally Protected Species of Edgecombe County Common Name Scientific name Federal Habitat Biological Status Present Conclusion Tar River Elliptio steinstansana E N No Effect s in ussel Red-cockaded Picoides borealis E N No Effect wood ecker No element occurences are listed on the NHP database within one mile of the crossline. During an on-site visit, no pine trees suitable for RCW foraging or nesting are near, or adjacent to the project area. Additionally, no suitable habitat for the Tar River Spinymussel was found. This project is not likely to jeopardize the continued existence of any of the federally protected species listed in Edgecombe County. No sites eligible for listing on the National Register occur within the area of potential effect. This project will not affect listed or eligible historic properties. REGULATORY APPROVALS USACE Section 404 Permit: The project qualifies for Nationwide Permit 13 (Bank Stabilization) and Nationwide Permit 33 (Temporary Construction, Access, and Dewatering). All permit conditions will be followed. NCDWQ Section 401 Certification: The project qualifies for 401 General Certification number 3495 and 3366. All conditions of the general certification will be followed. NCDWQBuffer Rules: As streambank stabilization activities are an allowable use, written authorization from the Division of Water Quality is required. if you have any questions or need any additional information, please contact Jamie Guerrero at (252) 296-3530.

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 ^ wetlands installation of Updated 11/1/2005 Page 9 of 13 freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streanLS. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, 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 may be 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. 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 (see DWQ website for most current version.). 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. 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 written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form. For additional information regarding the application process for the NCEEP, check the NCEEP website at http~//www nceep net/pal;es/inlieureplace htm.
