Sullins, Deputy Director b- :AZ? © Division of Water Quality February 18, 2004 Burke County DWQ Project No. 040132 SR 1419 (Bost Road) NCMA APPROVAL of 401 Water Quality Certification with Additional Conditions Mr. J. J. Swain, Jr., P.E. WET LAN ?,1401 Division Engineer N C Department of Transportation A 20(14 Post Office Box 3279 Asheville, North Carolina 28802 Dear Mr. Swain: You have our approval, in accordance with the attached conditions and those listed below, to impact 68 linear feet of an unnamed tributary to the Catawba River (38 linear feet of new pipe and 30 feet of riprap) in order to make improvements to NCSR 1419 (Bost Road) in Burke County. The project must be constructed in accordance with the application dated January 28, 2004 (received February 2, 2004), including the environmental commitments made in the application letter. 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 Vlater 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 211 .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. Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices in order to protect surface waters standards: a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the project. c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual. d. Any reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. 59 Woodfin Place Asheville, N.C. 28801 Telephone: 828/251-6208 Fax: 828/251-6452 Customer Service: 1-877/623-6748 Mr. J. J. Swain, Jr., P.E. February 19, 2004 Page Two 2. No waste, spoils, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the Preconstruction Notice Application. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur. 3. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Quality has released the project. 4. The Catawba River and its tributaries are classified as WS-IV waters at this location. 5. As two barrels will be installed, only one barrel should receive base flow and the barrel with the sill, should be installed to receive only stormwater flows. The top of the sill should be at or near bankfull elevation. 6. Temporary or permanent herbaceous vegetation should be planted on all bare soil within fifteen (15) days of ground disturbing activities to provide long-term erosion control. NCWRC encourages NCDOT to utilize on site vegetation and materials for streambank stabilization, when practicable. 7. Riparian vegetation must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. 8. Stormwater should be directed to vegetated buffer areas, grass lined ditches or other means appropriate to the site for the purpose of pre-treating stormwater runoff, and must not be routed directly into streams. Mowing of existing vegetated buffers is strongly discouraged, so that they may be utilized for stormwater sheet flow. 9. Culverts that are less than 48-inch in diameter should be buried to a depth equal to or greater than 20% of their size to allow for aquatic life passage. Culverts that are 48-inch diameter or larger should be buried at least 12 inches below the stream bottom to allow natural stream bottom material 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. If any of the existing pipes are perched, they shall be removed and replaced, and re-installed correctly, unless demonstrated that this is topographically unfeasible. 10. 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. 11. Riprap placed for bank stabilization should be limited to the stream bank below the high water mark and vegetation should be used for stabilization above the high water elevation. Riprap should not interfere with aquatic life passage during low flow conditions. 12. 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. 13. 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. 1.4. Excavation of the stream crossings and relocations 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. 15. If concrete is used during culvert installation (e.g., 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 fish kills. 16. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is strictly prohibited. 17. 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. Instream dredging has catastrophic effects on aquatic life and disturbance of the natural form of the stream channel will likely cause downstream erosion problems, possible affecting other landowners. 18. Rock check dams at culvert outlets should be removed at project completion to avoid blocking movement of aquatic life. 19. This certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone except for permitted areas associated with culvert conditions. Mr. J. J. Swain, Jr., P.E. February 19, 2004 Page Three 20. All work shall be performed during low flow conditions. 21. 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 each 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 or Mr. Mike Parker of the Asheville Regional Office at 828.251.6208. Sincerely, pm,-t- Alan W. Klimek, P.E.

Bost Road is currently a 20 feet wide paved road. Division of Highways plans to add a center turn lane with curb and gutter thereby increasing the typical section to 40 feet. Grading will be light. We propose to extend one existing double barrel culvert on an UT to the Catawba River. Total culvert extension will be 38 linear feet with an additional 30 linear feet of rip-rap. A sill will be placed within one barrel to restrict low flows into a single barrel. No stream relocation will be performed for the project. 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. 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. Mr. Steve Lund Page -2 SR 1419, Burke County January 28, 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). By copy of this letter, we request 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 Environmental Engineer, to comment on the above project. Temporary encroachment into the buffer zone of the UT will not be required. The stream is not classified as trout. A buffer variance will not be required. By copy of this letter, I am forwarding seven (7) copies of the application package to Cynthia Van der Wiele, NC Division of Water Quality, 401/Wetland Unit and an additional copy to Mike Parker, NC DWQ Asheville Regional Office for review and comment.

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/ncwetiatids/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 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 httE.//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): Page 6 of 8 Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): IX.
