Dear Mr. Adams:
You have our approval for the impacts listed below for the purpose described in your application
submitted to the Division of Water Resources (Division) November 30, 2021, and payment received
on November 30, 2021. The Division has determined that the proposed project and impact will
comply with water quality requirements covered by the attached Water Quality General
Certification Number 4135 and the conditions listed below, provided that you adhere to the
certification located at https://deq.nc.gov/about/divisions/water-resources/water-quality-
permitting/401-buffer-permitting-branch/general and the conditions listed below.
This certification is associated with the use of General Permit Number 14 once it is 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 Division has determined that the proposed project will comply with the water quality
requirements provided that you adhere to the conditions listed in the certification and to the
additional conditions listed below. The following proposed impacts are hereby approved. No other
impacts are approved, including incidental impacts. [15A NCAC 02H .0506(b)]

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 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)].
If you are unable to comply with any of the conditions of the attached Water Quality General
Certification or with the additional conditions itemized below, you must notify the Mooresville
Regional Office within 24 hours (or the next business day if a weekend or holiday) from the time
the permittee becomes aware of the circumstances.
The permittee shall report to the Mooresville Regional Office any noncompliance with, and/or any
violation of, stream or wetland standards [15A NCAC 02B .0200] including but not limited to
sediment impacts to streams or wetlands. Information shall be provided orally within 24 hours (or
the next business day if a weekend or holiday) from the time the permittee became aware of the
non-compliance circumstances.
Additional conditions (15A NCAC 02H .0507(c):
1. Mitigation must be provided for the proposed impacts as specified in the table below. The
Division has received an acceptance letter from the City of Charlotte Umbrella Stream and
Wetland Mitigation Bank (“Umbrella Bank”) to meet this mitigation requirement. Until the
Umbrella Bank receives and clears your payment, and proof of payment has been provided to
this Office, no impacts specified in this Authorization Certificate shall occur. For accounting
purposes, this Authorization Certificate authorizes payment to the Umbrella Bank to meet the
following compensatory mitigation requirement [15A NCAC 02H .0506(c)]:
Compensatory Mitigation
Required
River and Sub-basin
Number
Wetlands 0.186 (acres) Catawba (03050103)
1:1 ratio
Justification: A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. In determining that the proposed activity will
comply with state water quality standards (including designated uses, numeric criteria, narrative
criteria and the state’s antidegradation policy), the project must provide for replacement of
existing uses through compensatory mitigation.
2. Stormwater Management: The applicant may provide documentation that the project will not
impair water quality to the receiving stream(s) from stormwater runoff or provide an approved
stormwater management plan. Any high density project and/or project that exceeds density
thresholds must provide a stormwater management plan for the entire project, for review and
approval including all forms and pertinent items that complies with the high density
development requirements. Low density development. The plan may be approved by the
Division, State Stormwater Program or a local delegated authority. The plan shall consider the
impact of the volume and velocity of discharge and runoff to the receiving stream and adjacent
riparian areas to prevent scouring and erosions of the features.

02B.0607(h)
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. In
determining that the proposed activity will comply with state water quality standards (including
designated uses, numeric criteria, narrative criteria and the state’s antidegradation policy), 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. Diversion ditches and other stormwater conveyances as related to the sediment and erosion
control measures shall be matted and/or stabilized to reduce sediment lost and turbidity. This
includes interior/exterior slopes of sediment basins. 15A NCAC 02H .05606 (b)(3) and (c) (3)
Justification: Failure to reduce erosion of runoff conveyances and to provide for maximum
reduction of erosion on areas not related to ongoing construction, shortens basin holding times,
increases turbidity of discharge and creates a greater potential of bypass discharge.
4. Bare/fill slopes in excess of 10 feet in height and within 30 feet of surface water shall be matted.
15A NCAC 02H .0506 (b)(1) and15A NCAC 02H .502 (c)
Justification: A project that affects waters shall not be permitted unless the existing uses, and
the water quality to protect such uses, are protected. In determining that the proposed activity
will comply with state water quality standards (including designated uses, numeric criteria,
narrative criteria and the state’s antidegradation policy), 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
5. 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. 15A NCAC 02B .0203
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.
6. The permittee shall report to the DWR Mooresville Regional Office any noncompliance with,
and/or any violation of, stream or wetland standards [15A NCAC 02B .0200], including but not
limited to sediment impacts to streams or wetlands. Information shall be provided orally within
24 hours (or the next business day if a weekend or holiday) from the time the permittee became
aware of the non-compliance circumstances.
Citation: 15A NCAC 02H .0506(b); 15A NCAC 02H .0507(c)
Justification: Timely reporting of non-compliance is important in identifying and minimizing
detrimental impacts to water quality and avoiding impacts due to water pollution that precludes
any best use on a short-term or long-term basis.
7. No waste, spoil, solids, or fill of any kind shall occur in wetlands or waters beyond the footprint
of the approved impacts (including temporary impacts).
Citation: 15A NCAC 02H .0506; 15A NCAC 02H .0507(c)
Justification: 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.
8. All activities shall be in compliance with any applicable State Regulated Riparian Buffer Rules in
Chapter 2B of Title 15A in the North Carolina Administrative Code.
