R. Styles, P.E., District Engineer NCDOT Division 14 P.O. Drawer 250 Bryson City, NC 28713 Dear Mr. Styles: You have our approval, in accordance with the attached conditions and those listed below, to impact 189 linear feet (including 150 feet of stream relocation) of unnamed tributaries to the East Fork Tuckasegee River in order to improve SR 1749 (Woodring Cemetary Road) in Jackson County. The project should be constructed in accordance with your application dated February 1, 2002 and additional information received April 29, 2002. After reviewing your application, we have decided that this fill is covered by General Water Quality Certification No. 3375 corresponding to the U.S. Army Corps of Engineers Nationwide Permit Number 14. In addition, you should acquire any other federal, state or local permits before you proceed with your project including (but not limited to) Sediment and Erosion Control, Non-Discharge and Water Supply Watershed regulations. This approval will expire with the accompanying 404 permit unless otherwise specified in the Water Quality Certification. This approval is only valid for the purpose and design that you described in your application except as modified below. If you change your project, you must notify us, in writing, and send us a new application. If the property is sold, the new owner must be given a copy of this Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre or stream impacts exceed 150 linear feet, compensatory mitigation may be required as described in 15A NCAC 2H.0506 (h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the attached certification and any additional conditions listed below. Stream Relocation a. The stream relocation shall include it minimum of 50-foot buffers and use natural channel design. b. The stream relocation must be constructed in a dry work area, and stabilized before stream flows are diverted. Channel relocations shall be completed and stabilized prior to diverting water into the new channel. Whenever possible, channel relocations must be allowed to stabilize for an entire growing season. Vegetation used for bank stabilization shall be limited to native woody species, and should include establishment of a 30-foot wide wooded and an adjacent 20-foot wide vegetated buffer on both sides of the relocated channel. A transitional phase incorporating coir fiber and seedling establishment is allowable. Rip-rap may be allowed if it is necessary to maintain the physical integrity of North Carolina Division of Water Quality, 401 Wetlands Certification Unit, 1650 Mail Service Center, Raleigh, NC 27699-1650 (Mailing Address) 2321 Crabtree Blvd., Raleigh, NC 27604-2260 (Location) 919-733-1786 (phone), 919-733-6893 (fax), http://h2o.enr.state.nc.us/ncwetlands/ t the stream, but the applicant must provide written justification and the calculations used to determine the extent of rip-rap coverage requested. If this Office determines that the stream relocation or associated riparian area has become unstable, the stream shall be repaired or stabilized using only natural channel design techniques if possible. Additionally, the vegetation in the riparian shall be maintained and/or replaced according to the approved plans. Rip-rap and other hard structures may only be used if required by the Division of Land Resources or a Delegated Local Program. Lastly, all repair designs must be submitted to and receive written approval from this Office before the repair work is performed. 2. NCDOT shall use Best Management Practices for the Protection of Surface Waters (NCDOT March 1997) and Sedimentation and Erosion Control Guidelines for Sensitive Watersheds (15A NCAC 413 .0024) must be implemented prior to any ground-disturbing activities to minimize impacts to downstream aquatic resources. Temporary or permanent herbaceous vegetation shall be planted on all bare soil within 15 clays of ground-disturbing activities to provide long term erosion control. 3. In-stream work and land disturbance within the 25-foot wide buffer zone are prohibited during the trout spawning season of October 15 through April 15, or other conditions as determined by the North Carolina Wildlife Resources Commission, to protect the egg and fry stages of trout from sedimentation during construction. 4. The pipes required for this project shall be installed in such a manner that the original stream profiles are not altered (i.e. the depth of the channel must not be reduced by a widening of the streambed). Existing stream dimensions are to be maintained above and below locations of each culvert. If any of the existing pipes are perched, they shall be removed and replaced, and installed correctly. 5. All mechdnized equipment operated near surface waters must be regularly inspected and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. The presence of equipment in the channels must be minimized. Under no circumstances must rock, sand or other materials be dredged from the wetted stream channel under authorization of this permit, except in the immediate vicinity of the culverts. 6. Use of rip-rap for bank stabilization is to be minimized; rather, native vegetation is to be planted when practical. If necessary, rip-rap must be limited to the stream bank below the high water mark, and vegetation must be used for stabilization above high water. 7. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certificate of Completion" form to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the NC Division of Water Quality upon completion of the project. If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition that conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing. This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have any questions, please telephone Ms. Cynthia Van Der Wiele at 919.733.5715 or Mr. Mike Parker of the Asheville Regional Office at 828.251.6208. Sincerely, ox'A p".04 Gregory J. Thorpe, Ph.D. " Acting Director Attachment Pc: Wilmington District Corps of Engineers John Hendrix, USAGE Asheville Field Office NCDWQ Asheville Regional Office Central Files File Copy < <. 0;? 0 IFIS May 21, 2002 Mr. John Hendrix U. S. Army Corps of Engineers Regulatory Branch HLE COPY 151 Patton Avenue, Room 208 Asheville, North Carolina 28801-5006 SUBJECT: NCDOT Nationwide 404 Permit Application Pave SR 1749, Woodring Cemetery Road (Powell Road) - UT to Tuckaseegee River Jackson County, North Carolina Dear Mr. Hendrix: Mr. C.R. Styles of the North Carolina Department of Transportation is requesting a letter of concurrence from the North Carolina Wildlife Resources Commission (NCWRC) to renew a 404 permit from the U. S. Army Corps of Engineers. Staff biologists have reviewed the information provided by the applicant. A site visit was made on April 4, 2002 to further assess the potential for adverse impacts to fish and wildlife resources. These comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). The applicant proposes to grade, drain, base and pave primarily along the existing roadway of SR 1749, Woodring Cemetery Road. The project will require the extension and/or relocation of two culverts in an unnamed tributary of the Tuckaseegee River. Total culvert replacement and relocation impacts will be 39 feet. Additionally, a 150 feet of channel will be relocated. The channel relocation will be a step pool type B stream that is similar in profile to what is being impacted. The new channel will be constructed in the dry and will be stabilized with coir matting and seeded prior to diverting water. Existing vegetation will be transplanted where possible. r A Pave SR 1749, Woodring Cemetery Road 2 Jackson County, i1T Tuckaseegee River May 21, 2002 The Division of Water Quality classifies Tuckaseegee River as WS-III & B trout. The unnamed tributary is small but may support some trout downstream of the project near the Tuckaseegee River. The Tuckaseegee does in fact support trout. The NCWRC is concerned about potential project impacts to trout and other aquatic resources in this drainage; however, we can concur with the issuance of the 404 permit provided that he following conditions are placed on the subject permit: Adequate sedimentation and erosion control measures should be implemented and maintained on the project site to avoid impacts to downstream aquatic resources. Temporary or permanent herbaceous vegetation should be planted on all bare soil within 15 days of ground disturbing activities to provide long-term erosion control. Areas around stream crossings and adjacent to streams should be seeded by hand and mulched with erosion control matting instead of straw. 2. Culverts that are less than 48-inch diameter should have the floor of the barrel installed 20% of the diameter of the culvert below the level of the stream bottom. Culverts that are 48-inch diameter or larger should be placed with the floor of the barrel approximately 12 inches below the stream bottom to allow natural stream bottom materials to become established in the culvert following installation and to provide aquatic life passage during periods of low flow. This may require increasing the size of the culvert to meet flow conveyance requirements. Any perched outlets should be corrected during construction. 3. Under no circumstances should rock, sand, or other materials be dredged from the wetted stream channel under authorization of this permit, except in the immediate vicinity of the culverts. Instream dredging has catastrophic effects on aquatic life, and disturbance of the natural form of the stream channel will likely cause downstream erosion problems, possibly affecting other landowners. 4. Excavation of the stream crossings should be conducted in the dry, if possible. Sandbags, cofferdams, flexible pipe, or other diversion structures should be used to minimize excavation in flowing water. If concrete is used during culvert installation (headwalls), a dry work area should be maintained to prevent direct contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be discharged to surface waters due to the potential for elevated pH. 6. Rock check dams at culvert outlets should be removed at project completion to prevent blocking aquatic life movement. 7. Stormwater should be directed to buffer areas or retention basins and should not be routed directly into streams. Pave SR 1749, Woodring Cemetery Road 3 Jackson County, UT Tuckaseegee River May 21, 2002 8. Riprap placed for bank stabilization should be limited to the streambank below the high water mark, and vegetation should be used for stabilization above the high water elevation. 9. Removal of vegetation at the stream crossing and adjacent to streams should be minimized. Native trees and shrubs (e.g., rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) should be planted along the streambank to reestablish the riparian zone and to provide long-term erosion control in the vicinity of the road crossing and along the streams within dedicated rights of way. 10. The morphology of the new channel should be similar to the channel that is impacted. Native vegetation (e.g., tag alder, sycamore, dog hobble, rhododendron and silky dogwood) should be replanted on the banks of the new channel to provide shade and long-term stability. 11. Work in stream and within the 25-foot buffer is prohibited during the trout-spawning period of October l 5-Apri 1 15 to protect the egg and fry stages of trout. 12. All mechanized equipment operated near surface waters should be inspected and maintained regularly to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids or other toxic materials. 13. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is strictly prohibited. 14. This permit does not authorize the discharge of waste rock and dirt into the stream or- 25-foot buffer zone except for permitted areas associated with the fill of the old channel and culvert extensions. Thank you for the opportunity to review and comment on this project. Pending availability of field staff, the N('WRC may inspect the work site during or after construction.

State Project No.6.962106T(DWQ Major Permit Fee $475.00) Subject: Dear Mr. Hendrix: The North Carolina Department of Transportation is proposing to grade, drain, base and pave primarily along the existing roadway of SR 1749, Powell Road in Jackson County. In order to construct this project in accordance with our current secondary road standards, and due to the relocation of an unamed tributary to the Tuckasegee River(DEM CLASS WS-III&B TR),the addition or extension of two(2) pipe culverts in an unnamed tributary to the Tuckasegee River, we are requesting authorization under Section 404 of the Clean Water Act. I am sending a straight-line diagram with our proposed erosion control and construction limits at various sites along this project. In addition, a typical section of the road, drawings for the culvert relocation/extension in the unnamed tributary to the Tuckasegee River, general notes and standards on erosion control measures, and a marked County Map are enclosed. We propose to install the new culvert slightly below the existing stream bed elevation where bedrock is not encountered to minimize impact to Wildlife habitat and allow the existing stream gradient to remain as unchanged as physically possible. The best management practices will be used to minimize and control sedimentation and erosion on this project. The construction foreman will review all erosion control measures daily to ensure sedimentation and erosion controls are being effectively controlled. If the planned devices are not functioning as intended, they will immediately be replaced with better devices. The silt fences and other erosion control devices will be in place prior to pipe installation and will remain in place until the project is stabilized. P.O.

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. Impacts cannot be avoided. Culverts must be extended in order to gain the necessary width to construct SR 1749 to current NCDOT standards. All pipe replacements will be placed below the existing stream bed gradient so natural substrate can be re-established. 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 http.://h2o.enr.state.nc.us/wrp/index.htm.

The silt basin is built at the base of the ditch with its length being at least 2 times the width of the basin. The type-B silt basin is generally built in conjunction with temporary rock silt checks and other devices that control or slow down water flow. This device must be monitored closely and cleaned out on a regular basis until grass is established along the ditch line and sedimentation is no longer a problem. AREAS OF USE: • In conjunction with temporary rock silt checks and other devices used in drainage ditches. DESIGN CRITERIA: • Width - variable • Length - 2 times width • Depth - 2 ft. minimum storage - 1800 cubic feet/acre (equals L x W x D) 23 March, 1992 i r d!N G I U*) tjti 2 1 z J CL II III J IIIIiI 8 II j Ijil! ?

The a bu ltt--in sediment storage area around the outside perimeter o type- rock pipe inlet protection shall be used at pipe- inlets no larger than 36 inches in diameter where it is receiving flow from several directions. The type-A rock pipe inlet protection utilizes class-B stone lined with #5 or #57 stone ao protect dr inage pipe structures by trapping sediment before it enters. They have sediment g pit which is designed by the same procedures as a silt basin. AREAS OF USE: • At inlets to pipes no larger than 36 inches in diameter where it receives flow from several directions. • In areas where it can be cleaned and maintained on a regular basis. DESIGN CRITERIA: • Structural stone - class-B stone • Sediment control stone - #5 or #57 stone • Sediment storage area - 1800 cubic ft./acre • Dam height - 3 ft. minimum 33 March, 1992 Q d C 3 ? r JI L LL1 aJ W A F Z S C z Z@ O ¢ E^wZ ¢az t?nAFO-O ?OaF_ z O w a¢U°.^-'Zcwia° ?v?w owoawmz w WC4 FzG.0.

Rock silt screens shall be used to trap sediment transported and shall be placed in the stream below the construction site within the right-of- way or easement boundary. The rock silt screen utilizes class B stone lined with #5 or #57 stone to produce a ripple-effect in the stream to settle the larger sediment particles transported in the stream from the construction site. The trapped sediment shall be cleaned out before the device is removed from the stream. AREAS OF USE: • In live streams below construction sites where construction occurs in or adjacent to the stream. • In live streams below a culvert construction site. • Where it can be cleaned before it is removed from stream. DESIGN CRITERIA: Structural stone - class B stone Sediment control stone - # 5 or # 57 stone Dam height - 1.5 ft. minimum and 3 ft. maximum (shall not be higher than 1 ft. above normal flow of stream) 37 March, 1992 1 g a WW O 0- 0 Q m a J W Cs7 F s Z "?
