Dear Mr. DeVann:
Attached hereto is a copy of Certification No. WQC006144 issued to Gregory DeVann and United States
Coast Guard, dated July 31, 2023. 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.
Upon the presentation of proper credentials, the Division may inspect the property.
This Water Quality Certification shall expire on the same day as the expiration date of the corresponding
Section 404 Permit. The conditions shall remain in effect for the life of the project, regardless of the
expiration date of this Water Quality Certification.

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.
This approval and its conditions are final and binding unless contested [G.S. 143-215.5].

between 6.8 and 8.5 except that swamp waters may have a pH as low as 4.3 if it is the result of
natural conditions; (19) Turbidity: the turbidity in the receiving water shall not exceed 25 NTU; if
turbidity exceeds this level due to natural background conditions, the existing turbidity level shall

11. The permittee shall report to the DWR Wilmington 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

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.
12. When applicable, all construction activities shall be performed and maintained in full
compliance with G.S. Chapter 113A Article 4 (Sediment and Pollution Control Act of 1973).
Regardless of applicability of the Sediment and Pollution Control Act, all projects shall
incorporate appropriate Best Management Practices for the control of sediment and erosion so
that no violations of state water quality standards, statutes, or rules occur.
Design, installation, operation, and maintenance of all sediment and erosion control measures
shall be equal to or exceed the requirements specified in the most recent version of the North
Carolina Sediment and Erosion Control Manual, or for linear transportation projects, the North
Caroline Department of Transportation Sediment and Erosion Control Manual.

Justification: A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. Activities must not cause water pollution that
precludes any best use on a short-term or long-term basis. As cited in Stream Standards: (12)
Oils, deleterious substances, or colored or other wastes: only such amounts as shall not render
the waters injurious to public health, secondary recreation, or to aquatic life and wildlife, or
adversely affect the palatability offish, aesthetic quality, or impair the waters for any designated
uses; and (21) turbidity in the receiving water shall not exceed 50 Nephelometric Turbidity Units

along streambanks or within wetlands.
Citation: 15A NCAC 02H .0506(b); 15A NCAC 02H .0507(c)
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.
14. If the project is covered by NPDES Construction Stormwater Permit Number NCG010000 or
NPDES Construction Stormwater Permit Number NCG250000, full compliance with permit
conditions including the erosion & sedimentation control plan, inspections and maintenance,
self -monitoring, record keeping and reporting requirements is required.

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 conditions of waters be suitable for all best uses provided for in state rule
