Total project length will be 0.91 miles. The roadway will be widened from 16 feet to 18 feet with impervious surface area increasing by 0.22 acres. This project will require the replacement of six wet pipes and 0.1 acres of wetland impacts as shown below: Stream Impacts: Station Number Existing Structure Size Proposed Pipe Size Riprap Impacts feet Total Impacts at this Station ft. 0+42' 30'x 30" 50'x 36" 10 30 7+162 25'x 24" 55'x 24" 10 20 16+65 24'x 24" 45'x 36" 10 31 31+76 24'x 18" 40'x 18" 10 26 37+753 23'x 18" 70'x 24" ] 0 40 42+31 31'x 18" 50'x 24" 10 29 Total Stream Im acts = 176 feet This pipe has already been replaced due to clogging. Email notification was provided. 2 A private pipe on the outlet side will be cut back approximately 20 feet to accommodate our longer pipe. Approximately l0 feet of daylighted area will be maintained between our pipe outlet and the inlet of the private pipe. This area will be seeded and matted. P. O. 13ox 250, N.

Water from this pipe then runs our ditch for 30 feet before going through the existing cross line pipe inlet at station 37+60. We are proposing to eliminate this wet ditch by moving our pipe inlet to ~ 37+90. The private pipe will be cut back approximately 30 feet to accommodate our widening in that direction. Approximately 10 feet of daylighted area will be maintained between our pipe inlet and the outlet of the private pipe. Since this daylighted area will be flowing down our cut slope, it will be lined with fabric and armored with class B stone.

An impervious sandbag dike will be constructed approximately 20 feet upstream of the existing culverts to create a small pool. Clean water will temporarily be pumped around the construction areas and will be discharged downstream. Any dirty water located inside of the construction areas will be pumped into a silt bag if necessary. Total dewatered area for all wet pipes will be approximately 0.015 acres. Once the new pipes are in place, the impervious dikes will be removed and preconstruction streambed elevations will be restored. The wet pipe at station 0+42 carries Roaring Branch (Class: C+). The remaining wet pipes carry different unnamed tributaries to Roaring Branch. This project was reviewed for the presence of threatened and endangered species on January 26, 2007. This project will have no effect on any federally listed endangered plant or animal species. The State Historic Preservation Office has reviewed this project and did not request any survey work. 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. 11r. 111ontc 111atlhe~cs w SR 1331 (Virgil Greer Road) Page 3 Fehruarv 12.2007 By copy of this letter, it is requested that Mr. Ron Linville, Mountain Region Coordinator, with the North Carolina Wildlife Resources Commission comment directly to you concerning the 404 Natiomvide Permit application with a copy sent to me.

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. By utilizing the erosion control measures as shown in the attached drawings adverse impacts to streams in the area will be minimized. Since this is an existint; roadway the stream and wetland impacts cannot be avoided. However the replacement pipe lenPths will be the minimum needed to safely construct the paved roadway 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. 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 hnp~//h2o.enr.statc.nc.us/~~~ra/inde~.htm.
