APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Holder:
You have our approval, in accordance with the attached conditions and those listed below, to permanently
impact 20 linear feet (If) (10 If for increase in culvert length and 10 If for riprap structure stabilization) and to
temporarily impact 20 If (cofferdams) of an unnamed tributary to Lower Little River, a perennial stream, as
described in your application received by the Division of Water Quality (DWQ) on January 10, 2011. The
location of the project is State Road 1333 (Bebber Road) in Alexander County. After reviewing your .
application,, we havetdetermined that this project is covered by VWater,Quality general Certification Numbers
3820 Please notethat you should get any other federal', state or local permits before proceeding with your
project,, including those required py (but not limited to) Sediment and Erosion Control, Non-Discharge and
Water Supply Watershed regulations. This, approval will expire with the associated 404 permit unless
otherwise specified in the Water Quality Certification.
This approval is valid solely for the purpose and design that you described in your application (unless modified
below). Should your project change, you must notify the DWQ in writing and you may be required to submit a
new application. 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, 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 those listed below:
1. Unless otherwise approved in this certification, placement of culverts and other structures in open
waters and streams shall be placed below the elevation of the streambed by one (1) foot for all culverts
with a diameter greater than 48 inches and 20 percent of the culvert diameter for culverts having a
diameter less than 48 inches to allow low flow passage of water and aquatic life. Design and
placement of culverts, and other structures including temporary erosion control measures shall not be
conducted in a manner that may result in dis-equilibrium of wetlands or streambeds or banks,` adjacent
to or upstream and downstream of the above structures.' The applicant is required to provide evidence
that the egwlibrium Is being ma r talned If required-in-writing by NCDWQ: r

If this condition is unable to be met due to bedrock or other limiting features encountered during
construction, please, contact NCDWQ for guidance on how_ to proceed and to determine whether or not
a. permit modification. will be required.
2. The dimension, pattern and profile of the stream above and below the crossing shall not be modified.
.,Disturbed floodplains, and streams shall be restored to natural geomorphic conditions.
3. If concrete is used during construction, a dry work area shall be maintained to prevent direct contact
between curing concrete and stream water. Water that inadvertently contacts uncured concrete shall
not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and
fish kills.
4. During the construction of the project, no staging of equipment of any kind is permitted in waters of the
U.S. or protected riparian buffers.
5. The use of riprap above the normal high water mark shall be minimized. Any riprap placed for stream
stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life
passage.
6. Heavy equipment shall be operated from the banks rather than in the stream channel in order minimize
sedimentation and reduce the introduction of other pollutants into the stream.
7. No rock, sand or other materials shall be dredged from the stream channel except where authorized by
this certification
8. Temporary dewatering sites must be restored to,pre-existing conditions unless more natural
geomorphic conditions can be provided.
9. All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP
measures from the most current version of the NCDOT Construction and Maintenance Activities
manual such as sandbags, rock berms, cofferdams and other diversion structures shall be used to
prevent excavation in flowing water.
10. All mechanized equipment operated near surface waters must be regularly inspected and maintained to
prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.
11. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless
otherwise authorized by this certification.
12. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to
surface waters is prohibited.
13. A copy of this Water Quality Certification shall.be posted on the construction site at all times. In
addition, the Water Quality Certification and all subsequent modifications, if any, shall be maintained
with the Division Engineer and the on-site project manager.
14. Native. riparian vegetation must be re-established within the construction limits of.the project by the end
of the,growing season following completion of construction.

15. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum
extent practicable. If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, they shall be removed and the natural grade restored within'30 days after"the Division' of
Land_ Resources has released the project.

16. 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.
d. The reclamation measures and implementation must comply with the reclamation in accordance
