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 requiredto 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 30 days of the date that you receive this letter.

C. 28801-2714 Dear'-Mr. Johnson: The North Carolina Department of Transportation (NCDOT) is proposing to grade, drain, base, and pave SR 1609, Joe Wilson Road, primarily along the existing roadway. In order to construct this project in accordance with our current secondary road standards and due to the proximity of an outstanding resource water (Talley Mill Creek and tributaries, DEM Class C - ORW) and replacement of pipe culverts, we are requesting authorization under Section 404 of the Clean Water Act. I am sending a location map, straight-line diagram, plan-profile sheets, erosion control plans and details, and a U.S.G.S. map indicating project area and location of proposed pipe culverts along the road. We propose to install the new culverts slightly below the existing streambed elevations where bedrock is not encountered to minimize impacts to wildlife habitat and allow the existing stream gradients to remain as unchanged as is physically possibly. NO VP N,Ir. Bob Johnson Page 2 February 7, 1995 The best management practices will be used to minimize and control erosion and sedimentation on this project. The construction foreman will review all erosion control measures daily to ensure erosion and sedimentation are being effectively controlled. If the planned devices are not functioning as intended, they will immediately be replaced with better devices. The rock silt screens and other erosion control devices will be in place prior to pipe culvert construction and will remain in place until the project is stabilized. By copy of this letter I am asking Mr. David Yow, North Carolina Wildlife Resources Commission District 9 Environmental Coordinator, 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 Clean Water Act from the Division of Environmental Management. We would like to begin construction as soon as possible. If further information is required, please please call me at (704) 321-4105. Your early review and consideration will be greatly appreciated.

Temporary silt ditches shall be used at the toe of fill slopes to divert runoff into sediment basins, temporary rock sediment dams, temporary rock silt checks and/or other sedimentation control measures. Temporary silt ditches are approximately 1 ft. deep, 2:1 side slopes with an optional earth berm. AREAS OF USE: • Toe of fill slopes where fill exceeds 3 ft in vertical height. • Along streams to intercept flow and/or divert to a controlled outlet. VI-2 March, 1993 x .,I r?

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 = 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.

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.

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 CRITERIA: • Center of rock silt check shall be at least 1 foot lower than the outer edges (top of channel sides) • The spacing (ft.) _ (3 / % of ditch grade) X 100 ft.

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) VI-24 March, 1993 zi L y _ - Ll s a N O N Q m 1 Y m LL O a 0 w Z a FC) t: WZ °LO Z A? can zFa.O Fla, w E"•a ?ddWU) ? ?. zOWU W OW 04 , and ° Wa ztl)_ ?L) Om cZw Oa wW 0., E-w 0..a F0„-jz E="W? aaU)QE--o 0O<OZWW°o C' <z UOw °o°oz j[s.Ua.:Dw FZ W E-- ?ZW W v w F p m w ° W Z W> EE- W?

It is an apron of stone of a sufficient thickness to protect the outlet area from scouring out and causing off-site sedimentation damage. Pipe outlet energy dissipators should be built according to the guideline chart shown on page VIII-3 of this manual. AREAS OF USE: • Outlets of pipes and culverts to prevent scouring. DESIGN CRITERIA: • In accordance with chart on page VIII-3. • Filter fabric, or six inch layer of gravel, shall be used under stone. MATERIALS : • Filter fabric shall meet requirements of section 1056 of Standard Specifications for Roads and Structures, January 1, 1990, for type H filter fabric. YT?
