This certification allows you to use Nationwide Permit Number 26 when it is issued by the Corps of Engineers. This approval is only valid for the purpose and design that you described in your application. If youu change your project, you must notify us and you may be required to send us a new application. For this approval to be valid, you must follow the conditions listed in the attached certification. In addition, you should get any other federal, state or local permits before you go ahead with your project. 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.

IVATER Qier1l i'f ?- I The North Carolina Department of Transportation is proposing to extend two (2) pipes along Timberlane Road in Haywood County. The pipes carry tributaries of Richland Creek (DEM Class B). We are requesting authorization under Section 404 of the Clean Water Act to extend the pipes. I am sending drawings for pipe replacements, general notes and standards on erosion control measures, and a marked county map. 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 are being effectively controlled. If the planned devices are not functioning as intended, they will immediately be replaced with better devices. The rock silt screen 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. David Yow, North Carolina Resources Commission, District Fisheries Biologist to comment directly to you concerning the 404 Nationwide permit request. [t-*1115*1 Mr. Bob Johnson Page 2 July 31, 1995 A request is being made on this project. for a temporary encroachment in two (2) small tributaries of Richland Creek also, I am asking Mr. Yow and Mr. Ed Ingle, Area Roadside Environmental Engineer (NC DOT) to comment directly to me concerning the encroachment permits requested for these tributaries. Also by copy of this letter, I am requesting authorization to proceed under Section 401 of the Clean Water. Act from Division of Environmental Management. We would like to begin construction as soon as possible. If further information is required, please advise.

It is made of permeable filter fabric buried at the bottom, stretched and supported by steel posts. The silt fence reduces, the water flow while retaining the sediment. They may also be used to divert water flow to protected outlets. Silt fences need to be checked after each significant rainfall to ensure there effectiveness. They must be maintained on a regular basis. Silt fences shall not be installed across streams, ditches, or waterways. AREAS OF USE. • At toe of fill sections where sediment runoff can be stored and contained inside the project limits.

These type-B rock silt checks help reduce the flow velocity and are generally made of class-B stone. They are used in ditches during construction where the grade meets and/or exceeds 3%. AREAS OF USE: • In channels, roadside ditch outlets, temporary silt ditches, and temporary diversions. • In conjunction with type-B silt basins. DESIGN CRrMPJA: • Center of rock silt check shall be at least I foot lower than the outer edges (top of channel sides) • The spacing (ft.) = (3 / % of ditch grade) X 100 ft. 27 March, 1992 X LAJ ° o a tJ a ° o ¢ w > o O O O cn N m c i r, i?

March,1992 ROcx SILT SCREEN: A rock silt screen is a low-level dam structure to be used in streams below culvert sites. 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 stone • Dam height - 1.5 ft. minimum and 3 ft maximum (shall not be higher than 1 ft. above normal flow of stream) r 37 March, 1992 i a W rA3 in E•" Z a - Z z = C - ) . a2 t- C6 En Z Z C6- o W a o -C -C to 6 IA3 w oO z ga u- zw =2= -4 M-Co to C4 14 094 p1- 43 1 f" 0. f-0-3f-? f-63= V ?
