APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Bardsley,
You have our approval to conduct stream stabilization activities, in accordance with the attached conditions, along a
total of approximately 318 existing linear feet of Horsepen Creek located behind the Quaker Run Subdivision
Greensboro, NC in Guilford County, as described in your application received by the Division of Water Quality on
September 21, 2010 and additional information received October 21, 2010 and October 25, 2010. After reviewing your
application, we have determined that this activity is covered by General Water Quality Certification Number 3689,
which can be viewed on our web site at httD://www.ncwateEqualiiy.org/wetlands.html. This Certification allows you to
use Nationwide Permit Number 13 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 may be 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:
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:
Impacts

2. Native vegetation shall be used throughout this project within the areas identified for planting.
3. Natural fiber matting is recommended for streambank stabilization over plastic matting that can entrap small
animals.
4. Visual monitoring of the stabilized stream shall be conducted at a minimum of quarterly for the first year or two
bankfull events (whichever is longer), and then annually until it is determined that all structures and stream banks
are stable (particularly after storm events) and vegetation is successful. Any failures of structures, stream banks,
or vegetation may require future repairs or replacement to ensure the stability and water quality of the stream and
downstream waters.
The Division strongly recommends that the City re-evaluate the use of instream structures to divert storm flows
velocities away from the susceptible banks. Any use of instream structures must be approved by the Division
prior to installation.
6. Please note that the Division strongly prefers natural stream channel design for addressing unstable streambank
erosion. If adjacent sections of the Greenway Trail along Horsepen Creek require stabilization in the future the
Division will require a holistic and natural approach to resolve the issue rather than continued armoring of the
stream bank.
Upon finishing the project, the Applicant shall fill out and return the enclosed "Certificate of Completion"
to notify NCDWQ when all work included in the §401 Certification has been completed. This certificate
should be returned to the Winston-Salem Regional Office of the NC Division of Water Quality at the
address listed on the form. Along with the Certificate of Completion, please send photographs showing the
restored stream reach.
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 Sue Homewood in the DWQ Winston-Salem Regional Office at 336-771-4964 or
Ian McMillan in the Wetlands/401 Central Office in Raleigh at 919-715-4631.
Sincerely,

Coleen H. Sullins, Director
Division of Water Quality
