Director Division of Water Quality April 21, 2003 Wilkes County DWQ Project No. 030464 SR 1355 (Shoe Road) APPROVAL of 401 Water Quality Certification with Additional Conditions Mr. Heath Slaughter, Division Environmental Officer NCDOT Division 11 P.O. Box 250 North Wilkesboro, NC 28659 Dear Mr. Slaughter: You have our approval, in accordance with the attached conditions and those listed below, to impact 100 linear feet of streams. These impacts include two unnamed tributaries to Little Fork Creek and two unnamed tributaries to Old Taylor Branch. NCDWQ understands that these impacts are necessary in order to upgrade SR 1355 (Shoe Road) in Wilkes County. The project must be constructed in accordance with your application dated April 10, 2003 (received April 15, 2003). After reviewing your application, we have decided that this fill is covered by General Water Quality Certification No. 3404, corresponding to the U.S. Army Corps of Engineers Nationwide Permit Number 14. In addition, you must 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 valid solely for the purpose and design described in your application (unless modified below). Should your project change, you must notify the DWQ in writing and submit 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 the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or of total impacts to streams (now or in the future) 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. 1. For construction work in the vicinity of or draining towards Old Taylor Branch and its UT's, NCDOT shall implement Best Management Practices for the Protection of Surface Waters (NCDOT March 1997) and Design Standards for Sensitive Watersheds (15A NCAC 413 .0124). 2. NCDOT shall abide by the requirements for WS-II and High Quality Waters [ 15A NCAC 2B .0214 and 15A NCAC 2B .0224]. 3. NCDOT shall be subject to all conditions and/or moratoriums determined by NCWRC as necessary to protecting species and habitat, including a rainbow trout moratorium from January 1 through April 15. 4. Riparian vegetation must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. 5. The dimension, pattern, and profile of the stream and floodplain above and below each culvert shall not be modified by widening the stream channel or reducing the depth of the stream. The structures shall be designed and installed to allow for fish and other wildlife movement as well as prevent 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/ headcutting of the streams. DWQ understands that there are topographic constraints to pipe burial on this project. 6. Use of rip-rap for bank stabilization is to be minimized; rather, native vegetation is to be planted when practical. If rip-rap is necessary, it must be limited to the stream bank above the high water mark. Rip rap shall not be placed in the stream bottom. 7. Heavy equipment must be operated from the banks rather than in the stream channel in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream. 8. All mechanized 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. 9. 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. 10. 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. NCDOT is strongly advised to send in photographs upstream and downstream of the structure to document correct installation. 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 which 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.

Biologists with the North Carolina Wildlife Resources Commission are familiar with habitat values in the area. These comments are provided in accordance with the provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d) and the North Carolina Environmental Policy Act (G.S. 113A-1 through 113A-10; NCAC 25). The project will replace and upsize four existing CMPs with larger and longer CMPS. Miscellaneous riprap impacts will total 40 linear feet. New stream impacts will be 140 linear feet. Temporary dewatering is not indicated. Due to steepness in the area, wet pipes at stations 20+65, 85+78 and 109+32 will remain perched with energy dissipater pads. We will not object to the project as proposed provided the following conditions are implemented: 1. Instream work and land disturbance within the 25-foot wide buffer zone are prohibited during the rainbow trout spawning season of January 1 through April 15 to protect the egg and fry stages of trout. 2. Except for the culverts indicated above, culverts 48" or larger should be buried V into the streambed. Culverts less than 48 inches in diameter should be buried to a depth equal to or greater than 20% their size to allow for aquatic life passage. These measurements must be based on natural thalweg depths. SR1355, Shoe Road 2 April 16, 2003 All waters must flow through without freefalling or damming on either end during low flow conditions to maintain aquatic life and/or fish passage. 3. Any riprap used must not interfere with aquatic life movement during low flows. 4. The dimension, pattern, and profile of the stream above and below the barrel should not be modified by widening the stream channel or reducing the depth of the stream. 5. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 6. If concrete will be used, work must be accomplished so that wet concrete does not contact stream water. This will lessen the chance of altering the stream's water chemistry and causing a fish kill. 7. Heavy equipment should be operated from the bank rather than in the stream channel in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream. 8. Stringent erosion control measures should be installed where soil is disturbed and maintained until project completion. Sediment and erosion control measures shall adhere to the design standards for sensitive watersheds (15A NCAC 4B .0024). 9. Temporary or permanent herbaceous vegetation should be planted on all bare soil within 5 days of ground disturbing activities in the twenty-five (25) foot trout buffer to provide long-term erosion control. We encourage NCDOT to utilize onsite vegetation and materials for streambank stabilization when practicable. Thank you for the opportunity to review and comment on this project during the early planning stages. If you have any questions regarding these comments, please contact me at 336/769-9453.

W ETLANDS1401 GROUP (DWQ Permit Fee: $200) The NC Department of Transportation is scheduled to grade, drain, base and pave SR 1355 in Wilkes County. The roadway width will be increased from 14' to 18'. Total project length is approximately 2 miles. Impervious surface area will increase by approximately 1 acre. This project will require the replacement of four (4) wet cross lines as shown below: 1) Replace existing 50'x 24" CMP at station 20+66 with a 75'x 24" CMP. 2) Replace existing 55'x 24" CMP at station 44+25 with a 75'x 36" CMP. 3) Replace existing 40'x 24" CMP at station 85+78 with a 75'x 24" CMP. 4) Replace existing 60'x 36" CMP at station 109+32 with an 80'x 36" CMP. Miscellaneous rip-rap impacts will total 40 linear ft. or less. New stream impacts = 140 linear feet. ** Please note that this is a steep and curvy secondary road. The additional pipe lengths are needed to eliminate sharp curves along this roadway. **Due to slope, the wet pipes at stations 20+65, 85+78 & 109+32 will remain perched with energy dissipater pads underneath. None of these wet pipes contain suitable fish habitat anyway. Burying these pipes would adversely impact stream stability and would require additional piping. Construction of this project will require impacts to waters of the United States in the Yadkin River Basin. The above noted wet cross lines at stations 20+66 and 44+25 carry different 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. 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 existing roadway, the stream impacts cannot be avoided However, the replacement pipe lengths will be the minimum needed to safely construct the paved roadway The proposed additional pipe lengths are needed to eliminate sharp curves in the roadway, thus improving public safety. 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/ncwettands/stringide.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.
