Dear Mr. Pettyjohn:
You have our approval, in accordance with the attached conditions and those listed below, to incur the following impacts in order to
improve, widen and pave SR 1332 (Walnut Branch Rd) in Alleghany County.
• 1361inear feet of new impacts to four different unnamed tributaries to Elk Creek (96 feet of piping impacts, 40 feet of riprap);
• a total of 0.015 acres of temporary impacts from dewatering at all pipe replacement locations.
The project shall be constructed in accordance with your application dated January 8, 2007. After reviewing your application,. we
have decided that this fill is covered by General Water Quality Certification Nos. 3404 and 3366, corresponding•to the U.S. Army
Corps of Engineers Nationwide Permit Numbers 14 and 33 respectively. In addition, you should acquire any other federal, state or
local permits before you proceed with your project including (but not limited to) Sediment and Erosion Control, Non-Discharge and
Water Supply Watershed regulations. This approval will expire with the accompanying 404 federal permit. This condition
supercedes, condition No. 19 in the General Certification 3404 and condition No. 12 in the General Certification 3366.
This approval is valid solely for the purpose and design described in your application (unless modified below). Should your project
change, you must notify the Division of Water Quality(Division) and submit a new application. If the property is sold, the new owner
must be given a copy of this approval letter and certifications, and is thereby responsible for complying with all the conditions. If total
wetland fills for this project (now or in the future) exceed one acre, or if total impacts to streams (now or in the future) exceed 150
linear feet, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h) (6) and (7). For this approval to remain
valid, you must adhere to the conditions listed in the attached certification and any additional conditions listed below.
1. At various locations along this road widening, the stream channel is parallel, and immediately adjacent to, the road fill slope
and construction area. Extra care will be necessary in designing, installing, and maintaining proper erosion control measures
to ensure no impacts to stream at these locations. Should it become necessary to provide additional stream stabilization at
these parallel locations, a permit modification will be required.
2. Erosion and sediment control practices must be in full compliance with all specifications governing the proper design,
installation and operation and maintenance of such Best Management Practices in order to protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in
accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design
Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they
equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion
Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects,
including contractor-owned or leased borrow pits associated with the project.
c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in
accordance with the most recent version of the North Carolina Surface Mining Manual.
