Hunt, Jr., Governor Wayne McDevitt, Secretary A. Preston Howard, Jr., P.E., Director NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES June 15, 1998 Jackson County DWQ Project 980516 APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS Mr. 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 and those listed below, to impact 0.01 acres of wetlands or waters for the purpose of paving SR 1152A in Jackson County, as you described in your application dated June 10, 1998. After reviewing your application, we have decided that this impact is covered by General Water Quality Certification Number 3103. This certification allows you to use Nationwide Permit Number 14 when it is issued by the Corps of Engineers. 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. 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 except as modified below. 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 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, 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. Sediment and erosion control measures shall adhere to the design standards for sensitive watersheds (T 15A:04B.0024). 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 conforming 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. ow , Jr. P.E.

Field Office Room 75, Grove Park Ave. Asheville, NC 28801-2714 Dear Mr. Johnson: SECRETARY .JUN 0 1988 K The North Carolina Department of Transportation is proposing to grade, drain, base and pave primarily along the existing roadway of SR 1152A, Buck Creek Gap Road in Jackson County. In order to construct this project in accordance with our current secondary road standards and due to the replacement of one (1) pipe culvert in an unnamed tributary of Mill Creek (DEM Class WS III 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 the site along this project. In addition, a typical section of the road, drawings for the pipe replacement in the unnamed tributary of Mill Creek, 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 construction and will remain in place until the project is stabilized. 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. P. O. Box 250, Bryson City, N.C. 28713 Phone (828) 488-2131 Mr. Bob Johnson Page 2 June 2, 1998 Also by copy of this letter, I am requesting authorization to proceed under Section 401 of the Clear Water Act from Division of Environmental Management. In addition, I am asking Mr. Davis and Mr. Ed Ingle, Area Roadside Environmental Engineer (NCDOT), and Mr. Richard Phillips (DEHNR), 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. Yours truly, C. R. Styl P. E.

A TEMPORARY SILT FENCE: A temporary silt fence is commonly used at the toe of a fill section to prev site sedimentation. It is made of permeable filter fabric buried at the botton stretched and supported by steel posts. The silt fence reduces the water floN retaining the sediment. They may also be used to divert water flow to prote outlets. Silt fences need to be checked after each significant rainfall to ensu effectiveness. They must be maintained on a regular basis. Silt fences shall installed across streams, ditches, or waterways. AREAS OF USE: • At toe of fill sections where sediment runoff can be stored and con inside the project limits.

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.

The type-A 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 to protect drainage pipe structures by trapping sediment before it enters. They have a sediment storage 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 W CL_ CL 3 j r Cr _I W Z W W F ?

Rock silt screens shall be used to trap sediment transported by running water 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 • Dam height - 1.5 ft. minimum and 3 1 fr. above normal flow of stream) stone ft. maximum ( shall not be higher than 37 March, 1992 J co LLO O ...7 ?_ W z Z T C - Z F d d G F W Z O d- Z C Z 3 (n Z F 6.
