Deacon Road is currently a 12-14 feet wide gravel road. Division of Highways plans to pave the road 18 feet wide and increase the typical section. Grading will be moderate. We propose to extend one existing culvert on an UT to an UT to Bald Creek. Total culvert extension will be 10 linear feet. Existing channel morphology will be maintained upstream and downstream of the culvert. The culverts will be placed below existing streambed elevation. Riparian vegetation will be reestablished along disturbed areas associated with the culvert extension. A stream relocation will be performed on the UT from Station 19+80 to 21+15. Stream dimension, pattern and profile will be similar to the existing channel. Streambank reforestation will be conducted along the new stream channel. Stormwater will be diverted through grass-lined ditches or vegetated buffers prior to entering streams. No effect on federally listed species (threatened or endangered) or their habitats is anticipated. Fp Mr. Steve Lund Page -2 SR 1446, Yancey County February 2, 2004 As a part of the 401 Certification process, a copy of the application will be forwarded to the NC State Historic Preservation Office as required by Section 106 of the National Historic Preservation Act of 1966 and GS 121-12(a). The project has been previously cleared by HPO (ER-03-2375). By copy of this letter, we request that the North Carolina Wildlife Resources Commission Coordinator, to comment directly to the Corps concerning the permit request. By copy of this letter, we are asking Ed Ingle, Area Roadside Field Operations Engineer, to comment on the above project. Temporary encroachment into the buffer zone of the UT will be required. The stream is not classified as trout. A buffer variance will not be required.

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 existing secondarv road must be improved to meet current safetv standards for Daved roads. The culvert extension requested is the minimum necessary to establish an appropriate typical section for the roadway. The stream relocation is necessary to avoid a residence along the roadway. Riparian vegetation will be established on disturbed areas associated with the project construction. VIII. Mitigation - N/A Page 5 of 8 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/strrnide.htnil. 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 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 http://h2o.enr.state.nc.ushvrp/index.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): Amount of buffer mitigation requested (square feet): Page 6 of 8 Amount of Riparian wetland mitigation requested (acres): Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): IX. Environmental Documentation (DWQ Only) Does the project involve an expenditure of public funds or the use of public (federal/state/local) land? Yes X No ? If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ? No X If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ? No ? X. Proposed Impacts on Riparian and Watershed Buffers (DWQ Only) - N/A 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. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ? No X If you answered "yes", provide the following information: Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Zone* Impact (square feet) Multiplier Required Mitigation 1 3 2 1.5 Total * Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone 1. Page 7 of 8 If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0260. XI. Stormwater (DWQ Only) Describe impervious acreage (both existing and proposed) versus total acreage on the site. Discuss stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. The existing compacted gravel roadway acts as an impervious surface. Paving of the roadway should eliminate sedimentation from fines associated with gravel surface treatment. The roadway surface will be 40% of right of way acreage. Stormwater will be diverted through settling basins or grass lined buffers prior to entering the streams. XII. Sewage Disposal (DWQ Only)- N/A XIII. Violations (DWQ Only) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules? Yes ? No X Is this an after-the-fact permit application? Yes ? No X XIV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control). With regard to hazardous spill basins, the road is not classified as an arterial route, therefore hazardous spill basins are not required. 2/2 Appl' Ant/Agent's Tjgnature ( 'Date (Agent's signature is valid only if an authorization letter from the applicant is provided.

Tem or ft: deep, 2:1 side slopes with an optional earth bermilt ditches are approximately 1 AREAS OF USE: • Toe of fill slopes where fill exceeds 3 ft in vertical height. • Along streams to intercept flow and/or divert to a controlled outlet. ?i DTI March, 1993 •e TEMPORARY SILT FENCE: A temporary silt fence is commonly used at the toe of a fill section to prevent off- site sedimentation. It is made of permeable filter fabric buried at the bottom; stretched and supported by steel posts. The silt fence reduces the water flow while retaining the sediment. They may also be used to divert water flow to protected outlets. Silt fences need to be checked after each significant rainfall to ensure there effectiveness. They must be maintained on a regular basis. Silt fences shall not be installed across streams, ditches, or waterways. AREAS OF USE: • At toe of fill sections where sediment runoff can be stored and contained inside the project limits.
