The project begins at the end of pavement near station 22+25 and proceeds to the northwest for 0.47 miles. The roadway will be widened from 12 feet to 20 feet with impervious surface area increasing by 0.45 acres. This project will require the replacement of one wet pipe as shown below: Stream Impacts: Station Number Ezisting Structure Size Proposed Pipe Size Riprap Impacts feet Total Impacts at this Station ft. 39+25* 30'x 24" 45'x 24" 10 25 Total Stream Im acts = 25 feet * This pipe is currently perched due to slope and will remain perched after replacement with a riprap energy dissipater pad placed in the stream channel under the pipe outlet. The replacement of the existing pipe at station 39+25 will require temporary dewatering. An impervious sandbag dike will be constructed approximately 20 feet upstream of the existing culvert to create a small pool. Clean water will temporarily be pumped around the construction area and will be discharged into a buffer area located approximately 90 feet downstream of the sandbag dike. Any dirty water located inside the col~struction area will be pumped into a silt bag P. O. BOX 250, N. WILKESBORO, NC 28659 PHONE (336)667-9111 Fax (336)667-4549 ti Mr. John Thomas SR 1157 (Old Toe River Road) Page 2 December 15, ?006 if necessary. The dewatered area will total approximately 90 square feet or 0.002 acres. Once the new structure is in place, the impervious dike will be removed and preconstruction streambed elevations will be restored. The wet pipe in question carries an unnamed tributary to the North Toe River (Class: WS-V, Trout). This project was reviewed for the presence of threatened and endangered species on December 5, 2006. This project will have no effect on any federally listed endangered plant or animal species. Historic compliance work will be scheduled and concurrence with the State Historic Preservation Office will be obtained if required. The project impacts are minor in nature and should not remove or degrade existing water quality uses. Pipe sizes used will be the minimum necessary to create a safe roadway. By utilizing the erosion control measures outlined in the attachments to this application, downstream water quality standards will be protected. All appropriate BMPs will be used during construction. Attached is a Preconstruction Notification Form, plan sheets with proposed erosion control measures, a marked county map, a marked topography map and photographs. By copy of this letter, it is requested that Mr. Ron Linville, Mountain Region Coordinator, with the North Cazolina Wildlife Resources Commission comment directly to you concerning the 404 Nationwide Permit application with a copy sent to me. By copy of this letter, I am forwarding seven (7) copies of this application package to John Hennessy, NCDENR, Division of Water Quality, 401/Wetlands Unit, for his review. It is requested that any comments related to the 401 certification be forwazded directly to me with a copy sent to the US Army Corps of Engineers. We would like to begin construction as soon as possible. If further information is required, please let me know. Your early review and consideration will be appreciated.

Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be 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. Stream impacts cannot be avoided since this is an existing road. By utilizins; the erosion control measures as shown in the attached drawings, adverse impacts to streams in the azea will be minimized. All appropriate BMPs will be used during construction. Page 7 of 12 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 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 NCWRP 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, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide. html. 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 Page 8 of 12 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that you would like to pay into the NCWRP. Please note that payment into the NCWRP must be reviewed and approved before it can be used to satisfy mitigation requirements. Applicants will be notified early in the review process by the 401/Wetlands Unit if payment into the NCWRP is available as an option. For additional information regarding the application process for the NCWRP, check the NCWRP website at han://hzo.enr.statc.nc.us/~~rp/indc~.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): N/A Amount of buffer mitigation requested (squaze 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 (DWQ Only) 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. Photographs may also be included at the applicant's discretion.
