Subject: APPROVAL of 401 Water Quality Certification with Additional Conditions
Blenhein Storm Water Project
Dear Mr. Cole:
You have our approval, in accordance with the General Certification and those conditions
listed below, for the purpose proposed in your application dated July 22, 2014, and received by the
Division of Water Resources (the Division) on July 23, 2014. After reviewing your application, we
have determined that this project is covered by Water Quality General Certification Number 3883
and 3885, which can be viewed on our web site at http: / /portal.ncdenr.org /web /wq /swp /ws /401.
The General Certification allows you to use Nationwide Permit Numbers 3 and 27 once they are
issued to you by the U.S. Army Corps of Engineers (COE). 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. 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. Approved Impacts:
Type of Impact
Amount Approved
Temporary Impact
Amount Approved
Permanent Impact
Stream (NW 27)
2,355 acre
0
Stream (NW 3)
77 linear ft.
92 linear ft.
3. 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.

4. 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.
5. Base stream flow shall flow over the riprap place in the bottom of the channel. It is recommended
that the proposed "riprap" in the bed of the channel be embedded.
6. Appropriately sized and "fitted" rock/stone shall be utilized in the construction of cross vanes to
prevent undercutting and maintain proper grade control.
7. Diversion Ditches and other storm water conveyances as related to the sediment and erosion
control measures shall be matted and /or stabilized to reduce sediment loss and turbidity. This
includes interior /exterior slopes of sediment basins.
8. Use of native vegetation and other soft stream bank stabilization techniques must be used where
practicable instead of riprap or other bank hardening methods.
9. Stormwater 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.
10. 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.
11. 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.
12. Upon completion of the project, the applicant shall complete and return the enclosed "Certificate
of Completion" form to the 401/Wetlands Unit of the Division.
13. Continuing Compliance. The applicant (Charlotte - Mecklenburg Stormwater Services) 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 the Division 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, the Division 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, the Division 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.
This Certification can be contested as provided in Articles 3 and 4 of the General Statute
1506 by filing a written petition for an administrative hearing to the Office of the Administrative
Hearings (hereby known as OAH). A petition form may be obtained from the OAH at
