Subject: Approval of Individual 401 Water Quality Certification with Additional Conditions
Cedar Cliff Development Auxiliary Spillway Upgrade Project
USACE Action ID. No. SAW-2015-02543
Attached hereto is a copy of Certification No. Certification No. WQC004077 issued to Mr. Jonathan Wise
and Duke Energy Carolinas, LLC, dated October 20, 2021. This Certification replaces the Certification
issued on September 20, 2020. This approval is for the purpose and design described in your application.
The plans and specifications for this project are incorporated by reference as part of this Water Quality
Certification. If you change your project, you must notify the Division and you may be required to submit
a new application package with the appropriate fee. If the property is sold, the new owner must be given
a copy of this Certification and is responsible for complying with all conditions. [15A NCAC 02H
.0507(d)(2)].
This Water Quality Certification does not relieve the permittee of the responsibility to obtain all other
required Federal, State, or Local approvals before proceeding with the project, including those required
by, but not limited to, Sediment and Erosion Control, Non -Discharge, Water Supply Watershed, and
Trout Buffer regulations.
This Water Quality Certification neither grants nor affirms any property right, license, or privilege in any
lands or waters, or any right of use in any waters. This Water Quality Certification does not authorize
any person to interfere with the riparian rights, littoral rights, or water use rights of any other person
and does not create any prescriptive right or any right of priority regarding any usage of water. This
Water Quality Certification shall not be interposed as a defense in any action respecting the
determination of riparian or littoral rights or other rights to water use. No consumptive user is deemed
by virtue of this Water Quality Certification to possess any prescriptive or other right of priority with
respect to any other consumptive user regardless of the quantity of the withdrawal or the date on which
the withdrawal was initiated or expanded.
Upon the presentation of proper credentials, the Division may inspect the property.

CONDITIONS OF CERTIFICATION [15A NCAC 02H .0507(c)]:
1. The NC Wildlife Resource Commission (NCWRC) shall be consulted to determine the preferred rock
spoil locations within the lake.
Citation: 15A NCAC 02H .0506(b(1)); 15A NCAC 02H .0507(c)
Justification: In order to protect against impairment of water quality standards and best usage of
receiving and downstream waters, water quality based management practices must be employed to
protect against direct or indirect discharge of waste or other sources of water pollution. Surface

water quality standards require that conditions of waters be suitable for all best uses provided for in
state rule (including, at minimum: aquatic life propagation, survival, and maintenance of biological
integrity, wildlife, secondary contact recreation, agriculture) and that activities must not cause water
pollution that precludes any best use on a short-term or long-term basis.

Justification: A project that affects waters shall not be permitted unless the existing uses (including
aquatic life propagation and biological integrity), and the water quality to protect such uses, are
protected. Protections are necessary to ensure any remaining surface waters or wetlands, and any
surface waters or wetlands downstream, continue to support existing uses during and after project
completion. The Division must evaluate if the activity has avoided and minimized impacts to waters,
would cause or contribute to a violation of standards, or would result in secondary or cumulative
impacts.
3. The Permittee shall adhere to the Water Quality Monitoring Plan submitted to the Division on May
19, 2019. Water Quality Monitoring shall continue for a minimum of 36 months post construction
completion. The Permittee shall submit an annual summary report of the monitoring data to the

movement by wave, current action, or stream flows, and shall consist of clean rock or masonry
material free of debris or toxic pollutants. Rip -rap shall not be installed in the streambed except in
specific areas required for velocity control and to ensure structural integrity of bank stabilization
measures.

discharge must immediately notify the Department, or any of its agents or employees, of the nature,
location, and time of the discharge and of the measures which are being taken or are proposed to be
taken to contain and remove the discharge. This action is required in order to contain or divert the
substances to prevent entry into the surface waters. Surface water quality standards require that
