Hensley 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 light to moderate. We propose to extend two existing culverts on Little Hensley Branch. Total culvert extensions will be 20 linear feet. Existing channel morphology will be maintained upstream and downstream of the culverts. The culverts will be placed below existing streambed elevation. Riparian vegetation will be reestablished along disturbed areas associated with the culvert extensions. Stormwater will be diverted through grass-lined ditches or vegetated buffers prior to entering streams. No significant effect on federally listed species (threatened or endangered) or their habitats is anticipated. By copy of this letter, we request Owen Anderson, North Carolina Wildlife Resources Commission Mountain Region Coordinator, to comment directly to the Corps concerning the permit request. p,? v, Mr. Steve Lund Page -2 SR 1458, Yancey County January 8, 2002 By copy of this letter, we are asking Ed Ingle, Area Roadside Environmental Engineer, to comment on the above project. Temporary encroachment into the buffer zone of the Little Hensley Branch will be required for project stations 12+00 to 36+80. The stream is classified as trout. A buffer variance will be required. By copy of this letter, I am forwarding seven (7) copies, of the application package to Cynthia Van der Wiele, NC DENR, Division of Water Quality, 401/Wetland Unit for review and comment. Please charge the application processing fee of $200.00 to work order # 6.902240. Please forward comments directly to the Corps with copy to Division 13 Environmental Officer. Your earliest consideration for this request would be greatly appreciated. If you have any questions or information needs, please contact me at (828) 251-6287. Sincerely, . o? Ro r D.

Riparian vegetation will be established on disturbed areas associated with the project construction. The proposed impacts are on small spring fed streams. 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. Page 5 of 8 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/stlmgide.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. 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:i/h2o.enr.state.nc.us/wrp/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): 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) Page 6 of 8 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) 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 213 .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 teet perpendicular trom near oanx of cnannei; Lone.4 extenas an additional 20 feet from the edge of Zone 1. 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. Page 7 of 8 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 approximately 40 % of right of way area. Stormwater will be diverted through settling basins or grass lined buffers prior to entering the streams. XII. Sewage Disposal (DWQ Only) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. 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.
