APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Swartley:
The North Carolina Division of Forest Resources has our approval, in accordance with the attached
conditions, to conduct stream restoration, enhancement, and preservation activities along a total of 650 linear
feet of an unnamed tributary to Purlear Creek and to fill drainage ditches and remove fill material on 2.4 acres
of herbaceous wetlands, all .located within the Rendezvous Mountain Educational State Forest in Wilkes
County as described in your application received by the Division of Water Quality on March 8, 2006 and in
additional information received on April 18, 2006. After reviewing your application, we have determined that
this activity is covered by General Water Quality Certification Number 3495, which can be viewed on our
web site at http://www.ncwaterquality.org/wetlands.html. This Certification allows you to use Nationwide
Permit Number 27 when it is issued by the U.S. Army Corps of Engineers. In addition, you should secure any
other applicable federal, state or local permits before you proceed with your project, including (but not limited
to) those required by Sediment and Erosion Control, Non-Discharge, and Water Supply Watershed
regulations. Also, this approval will expire when the accompanying 404 permit expires unless otherwise
specified in the General Certification.
This approval is valid only for the purpose and design that you have described in your application. If you
change your project, you must notify us in writing, and you maybe required to send us a new application for a
new certification. If the property is sold, the new owner must be given a copy of the Certification and
approval letter and is thereby responsible for complying with all conditions. For this approval to be valid,
you must follow the conditions listed in the attached certification, as well as the additional conditions
listed below:
1. The following impacts are hereby approved as long as all other specific and general conditions of this
Certification are met. No other impacts, including incidental impacts, are approved:

2. Appropriate sediment and erosion control measures which equal or exceed those outlined in the most
recent version of the North Carolina Erosion and Sediment Control Planning and Design Manual or the
North Carolina Surface Mining Manual (available from the Division of Land Resources at NCDENR
regional offices or the central office), whichever is more appropriate, shall be designed, installed and
maintained properly to assure compliance at all times with the North Carolina water quality standards
that are applicable to Class WS-IV waters as described in ISA NCAC 02B .0216 Fresh Surface Water
Quality Standards For Class WS-IV Waters. Such measures must equal or exceed the requirements
specified in the most recent version of the North Carolina Sediment and Erosion Control Manual.
These measures must be maintained on all construction sites, borrow sites, and waste pile (spoil) sites,
including contractor owned and leased borrow pits, which are associated with the project.
3. 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 measures in wetlands or waters is
unavoidable, they shall be removed and the natural grade restored within six months of the date that the
Division of Land Resources has released the project.
4. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the
footprint of the impacts depicted in the Pre-Construction Notification. All construction activities,
including the design, installation, operation, and maintenance of sediment and erosion control "Best
Management Practices" shall be performed so that no violations of state water quality standards,
statutes, or rules occur.
5. The replacement culvert required for this project shall be installed in such a manner that the design
stream profile is not altered (i.e. the depth of the channel must not be reduced by a widening of the
streambed). Design stream dimensions (including the pattern and profile) are to be maintained above
and below the location of the culvert. The culvert shall be designed and installed to prevent head cutting
of the stream. If the culvert becomes perched, the appropriate stream grade shall be re-established or, if
the culvert is installed in a perched manner, the culvert shall be removed and re-installed correctly. The
Applicant must submit a plan and receive written approval from this Office to address any head cutting
that will occur as a result of this project (e.g., use of cross vanes downstream of the culvert).
6. If riprap is required for energy dissipation and scour protection, it shall be limited to the minimum
dimensions specified by appropriate engineering calculations. Riprap may only be used below the
normal high water level. The design grade and elevation of the stream's cross-section must be
maintained. Riprap placed in the streambed must be inserted into the bed matrix to a depth sufficient to
provide the thickness of riprap required for scour protection. The elevation of the streambed must not be
increased by the placement of riprap. Placement of riprap must not result in destabilization of the
streambed or banks upstream or downstream of any crossing.
7. Upon finishing the project, the Applicant shall fill out and return the enclosed "Certificate of

Mr. William A. Swartley
Page 3, DWQ# 06-0387

Completion" to notify NCDWQ when all work included in the §401 Certification has been completed.
This certificate should be returned to the 401/Wetlands Unit of the NC Division of Water Quality at the
address listed on the form. Along with the Certificate of Completion, please send photographs showing
all restored stream reaches and the culvert installation site.
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, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. 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 Daryl Lamb in the DWQ Winston-Salem Regional Office at (336)
771-4959 or Ian McMillan in the Central Office in Raleigh at [phone].
Sincerely,
Alan W. Klimek, P.E.
