Hunt, Jr., Governor Wayne McDevitt, Secretary Kerr T. Stevens, Director 11k,?WAA NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES July 22, 1999 Jackson County WQC 401 Project # 990763 APPROVAL of 401 Water Quality Certification C. R. Styles NC DOT PO Box 250 Bryson City, NC 28713 Dear Mr. Styles: You have our approval, in accordance with the attached conditions, to place fill material for the purpose of paving SR 1359, as you described in your application dated July 14, 1999. After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Number 3103. This Certification allows you to use Nationwide Permit Number 14 when the Corps of Engineers issues it. In addition, you should get any other federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified in the General Certification. This approval is only valid for the purpose and design that you described in your application. If you change your project, you must notify us and you may be required to send us a new application for a new certification. If the property is sold, the new owner must be given a copy of the 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, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions listed in the attached certification. 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, P.O. Box 27447, Raleigh, N.C. 27611-7447. 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 John Dorney at 919-733-1786.

DAVID MCCOY GOVERNOR SECRETARY June 25, 1999 Jackson County SR 1359 Mr. Bob Johnson 215 Army Corps of Engineer Reg. Field Office Room 75, Grove Park Ave. Asheville, NC 28801-2714 Dear Mr. Johnson: The North Carolina Department of Transportation is proposing to grade, drain, base and pave primarily along the existing roadway of SR 1359, River Road in Jackson County. In order to construct this project in accordance with our current secondary road standards and due to the replacement and extension of one (1) pipe culvert and the addition of one (1) pipe culvert in two unnamed tributaries of the Tuckasegee River (DEM Class B, Tr), 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 pipe replacement/extension and the pipe addition in the unnamed tributaries of the Tuckasegee River, general notes and standards on erosion control measures, and a marked County Map are enclosed. We propose to install the new culverts 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 construction and will remain in place until the project is stabilized. P.O. Box 250, Bryson City, NC 28713 Phone (828) 488-2131 Mr. Bob Johnson Page 2 June 25, 1999 By copy of this letter I am asking Mr. Mark Davis, Habitat Coordinator Western Mountain District, of the NCWRC to comment directly to you concerning the 404 Nationwide permit request. Also by copy of this letter, I am requesting authorization to proceed under Section 401 of the Clear Water Act from Division of Water Quality. In addition, I am asking Mr. Davis and Mr. Ed Ingle, Area Roadside Environmental Engineer (NCDOT), and Mr. Richard Phillips (DENR), to comment directly to me concerning this permit request. We would like to begin construction as soon as possible. If further information is required, please advise. Your early review and consideration will be appreciated. You uly, C. les, P. E.
