Sullins Governor Director Natural Resources Dee Freeman Secretary March 13, 2009 Macon Courtly DWQ Project No. 090231 NCSR 1506 (Gregory Road) APPROVAL, of 401 Water Quality Certification with Additional Conditions Mr. J. 13. Selzer, P.E. Division 14 Engineer N C Department of Transportation 253 Webster Road Sylva, North Carolina 28779 Dear Mr. Selzer: You have our approval, in accordance with the attached conditions and those listed below, for the following impacts in two (2) unnamed tributaries to Ammons Creek, for the purpose of widening and making improvements to NCSR 1506 (Gregory Road) in Macon County: Stream Impacts in the Little Tennessee River Basin Site Permanent Temporary Fill in Permanent Fill in Temporary Total Stream Stream Fill in Intermittent Perennial Stream Dewatering in Impact Impacts Intermittent Stream (linear ft) (linear ft) Perennial Stream (linear ft) Requiring Stream (linear ft) Mitigation linear fl (linear ft) Site 1 0 U 20 70 90 U Site 2 0 0 14 70 84 0 Total 0 U 34 140 174 0 Total Stream Permanent Impact for Project: 34 linear feet. Temporary Impact for Project: 140 linear feet. The project should be constructed in accordance with your application dated February 25, 2009 (received March 6, 2009), including the environmental commitments made in the application letter. After reviewing your application, we have decided that these impacts are covered by General Water Quality Certification No. 3704, 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 1srosion Control, Non- Discharge and Water Supply Watershed regulations. Phis 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 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 conditions. If total wetland fills for this project (now of in the future) exceed one acre,.or if 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 SURFACE WATER PROTECTION SECTION -Asheville Regional Office 2090 U.S. 70 Highway.

NorthCarolina Naturally Mr..1. B. Setzer, PL March 13. 2009 Page Two (7). For this approval lobe valid, you must follow the conditions listed in the attached certification and anv additional conditions listed below. I . There shall be no excavation from or waste disposal into, jurisdictional wetlands or waters associated with this permit without appropriate modification. Should waste or borrow sites, or access roads to waste or borrow sites, be located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road construction activities. 2. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this Certification. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored upon completion of the project. 3. Adequate sedimentation and erosion control measures must be installed and maintained on the project site to minimize sediment transport to downstream aquatic resources. 'T'emporary cover (wheat, millet or similar annual grain) or permanent herbaceous cover shall be planted on all bare soil as soon as possible following ground disturbing activities. Erasion control mating shall be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas. Matting should be secured in place with staples or wherever possible, live stakes of native trees. Straw mulch and tall fescue shall not be used in riparian areas. 4. If multiple pipes or barrels are required, they shall be designed to mimic the natural stream cross section as closely as possible including pipes or barrels at flood plain elevation and/or sills where appropriate. Widening the stream shall be avoided. Stream channel widening at the inlet or outlet end of structures typically decreases water velocity causing sediment deposition that requires increased maintenance and disrupts aquatic life passage. 5. For projects impacting waters classified by the NC Environmental Management Commission as Trout (,rr), High Quality Waters (FIQW) or Water Supply I or 11 (WS-1, WS-11), stormwater shall be directed to vegetated buffer areas, grass-lined ditches or other means appropriate to the site for the purpose of pre-treating stormwater runoff prior to discharging directly into streams. Mowing of existing vegetated buffer areas is strongly discouraged. 6. Native riparian vegetation (e.g. rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) nmst be reestablished within the construction limits of the project by the end of the growing season following completion of construction. 7. The use of riprap above the Normal high Water Mark shall be minimized. Any riprap placed for stream stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage. 8. Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes aquatic life passage. Bioengineering boulders or structures should be properly designed, sized and installed. 9. Heavy equipment shall be operated from the banks rather than in the stream channels in order to minimize sedimentation and reduce the introduction of other pollutants into the stream. 10. All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent contamination of stream waters fiom fuels, lubricants, hydraulic fluids, or other toxic materials. 12. The Pcrmiltce shall ensure that the final design drawings adhere to the permit and to the permit drawings submitted for approval. 13. Discharging hydrosecd mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. 14. No rock, sand or other materials shall be dredged from the stream channel, except where authorized by this certification. 15. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise authorized by this certification. 16. The outside buffer, wetland or water boundary located within the construction corridor approved by this authorization shall be clearly marked by highly visible fencing prior to any land disturbing activities. Impacts to areas within the fencing are prohibited unless otherwise authorized by this certification. I- Mr. J. B. Selzer, IT March 13, 2009 Page Three 17. A copy of this Water Quality Certification shall be maintained on the construction site at all times. In addition, the Water Quality Certification and all subsequent modifications, if any, shall be maintained with the Division Engineer and the on-site project manager. 18. The issuance of this certification does not exempt the Permittee form complying with any and all statutes, rules, regulations or 19. The pcrmittee and its authorized ordinances that may be imposed by other government agencies (i.e. local, state, and federal) having jurisdiction, including but not limited to applicable buffer rules, stormNvater management rules, soil erosion and sedimentation control requirements, etc. agents shall conduct its activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with §303(4) of the Clean Water Act) and any other appropriate requirements of State or Federal law. If DWQ determines that such standards or laws are not being met (including failure to sustain a designated or achieved use) or that State of Federal law if being violated, or that further conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification 20. The Perrniltee shall report any violations of this certification to the Division of Water Quality within 24-hours of discovery. 21. Upon completion of the project, the NCDOT Division Engineer shall complete and return the enclosed "Certificate of Completion Form" to notify NCDWQ when all work included in the §401 Certification has been completed. This form shall be returned to the Transportation Permitting Unit of the NC Division of Water Quality, 2321 Crabtree Blvd., Suite 250, Raleigh, North Carolina 27604.
