Box 3279 Asheville, NC 28802 Dear Mr. Tolar: A&4 ID EHNR October 7, 1996 Madison County DWQ Project # 960924 You have our approval to place fill material in 0.01 acres of wetlands or waters for the purpose of constructing a road improvement at SR 1593, as you described in your application dated 11 September 1996. After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Number 2735. This certification allows you to use General Permit Number 031 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 you 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. 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. Sincerely, NIA Woe n Howard, r. P .E. .

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.

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.

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 pipesand 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.

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 ! . ----- zZ m LL 0, LL : o l a 3 w W > w LL w a m I .J \•1 zZ mm LL 0 00 W F Z d FC?7z 0?QZZ V) QQ (L< V) ¢..,?W QExo z Z F a O E- wOd¢wO U'ow?? ?., Z O ZC?CY»UC? ° mdw w,? 04 ?
