APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Hinson:
April 15, 2011
DWQ# 11-0313
Mecklenburg County
You have our approval, in accordance with the general certification and those conditions listed
below, to impact 671 linear feet (If) of unnamed stream to Gum Branch Creek in order to completed
the proposed project in Mecklenburg County, as described in your application received by the
Division of Water Quality (DWQ) on April 5, 2011. After reviewing your application; we have
determined that this project is covered by Water Quality General Certification Numbers 3687 and
3689, which can be viewed on our web site at http://portal.ncdenr.org/web/wq/swp/ws/401. The
General Certifications allow you to use Nationwide Permit Numbers 3 and 27 once they are issued to
you by the U.S. Army Corps of Engineers. Please note that you should get any other federal, state or
local permits before proceeding with your project, including those required by (but not limited to)
Sediment and Erosion Control, Non-Discharge, and Water Supply Watershed regulations.
The above noted Certifications will expire when the associated 404 permits expire unless
otherwise specified in the General Certification. 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 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.
In addition to the requirements of the certification, you must also comply with the following
conditions:
1. The Mooresville Regional Office shall be notified in writing once construction at the approved
impact areas has commenced.

2. Proper construction technique, header stone size and shape shall be utilized in the construction of
the cross vane. A person with experience with stream work/construction is highly recommended to
oversee the project.
3. Proposed tree/vegetative plantings should include early succession species to establish quick cover.
4. Existing streambed substrate shall be utilized to the maximum extent practicable.
5. Culverts placed in streams/wetlands shall be installed "in the dry". Immediately upon completion
of the installation, water flow shall be returned to its natural course. Existing stream dimensions
(including the cross section dimensions, pattern, and longitudinal profile) must be maintained (or
restored via constructed benches) above and below locations of each culvert. If any of the
existing pipes are or become perched, the appropriate stream grade shall be re-established or, if
the pipes installed in a perched manner, the pipes shall be removed and re-installed correctly.
6. Use of native vegetation and other soft stream bank stabilization techniques must be used where
practicable instead of riprap or other bank hardening methods. If riprap is necessary, it shall not be
placed in the streambed, unless approved by DWQ.
7. Storm water discharge structures at this site shall be constructed in a manner such that the potential
receiving streams (of the discharge) will not be impacted due to sediment accumulations, scouring
or erosion of the stream banks.
8. 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 Preconstruction Notification application. All construction
activities associated with this project shall meet, and/or exceed, those requirements specified in the
most recent version of the North Carolina Sediment and Erosion Control Manual and shall be
conducted so that no violations of state water quality standards, statutes, or rules occur.
9. 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 two months of the date the
Division of Land Resources has released the project.
10. Upon completion of the project, the applicant shall complete and return the enclosed "Certificate of
Completion" form to the 401 /Wetlands Unit of the NC DWQ.
11. Continuing Compliance. The applicant (City of Charlotte) shall conduct all activities in a manner so
as not to contravene any state water quality standard (including any requirements for compliance
with section 303(d) of the Clean Water Act) and any other appropriate requirements of state and
federal law. If DWQ determines that such standards or laws are not being met (including the failure
to sustain a designated or achieved use) or that state or federal law is being violated, or that further
conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification to
include conditions appropriate to assure compliance with such standards and requirements in
accordance with 15 A NCAC 2H.0507(d). Before codifying the certification, DWQ shall notify the
applicant and the US Army Corps of Engineers, provide public notice in accordance with 15A NCAC
2H.0503, and provide opportunity for public hearing in accordance with 15A NCAC 2H.0504.
Any new or revised conditions shall be provided to the applicant in writing, shall be provided to the
United States Army Corps of Engineers for reference in any permit issued pursuant to Section 404
of the Clean Water Act, and shall also become conditions of the 404 Permit for the 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 that conforms to Chapter 1506 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 DWQ under Section 401 of the Clean Water Act. If you have
any questions, please telephone Mr. Alan Johnson in the Mooresville Regional Office at 704-663-1699
or Ms. Cyndi Karoly in the Central Office in Raleigh 919-733-9721.
Sincerely,
