Dear Mr. Edwards:
Attached hereto is a copy of Certification No. WQC006541 issued to Doug Edwards and Vesta North
Carolina, PBLCC, dated January 12, 2024. 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.
Non-compliance with or violation of the conditions herein set forth may result in revocation of this
Water Quality Certification for the project and may also result in criminal and/or civil penalties.
If you are unable to comply with any of the conditions of this Water Quality Certification you must notify
the Washington 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 Washington 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.
This approval and its conditions are final and binding unless contested [G.S. 143-215.5]. Please be aware
that impacting waters without first applying for and securing the issuance of a 401 Water Quality
Certification violates Title 15A of the North Carolina Administrative Code (NCAC) 2H .0500. Title 15A

construction or operation of facilities will result in a discharge into navigable waters, including wetlands,
as described in 33 Code of Federal Regulations (CFR) Part 323. It also states any person desiring
issuance of the State certification or coverage under a general certification required by Section 401 of
the Federal Water Pollution Control Act shall file with the Director of the North Carolina Division of
Water Quality. Pursuant to G.S. 143-215.6A, these violations and any future violations are subject to a
civil penalty assessment of up to a maximum of $25,000.00 per day for each violation.
This Certification can be contested as provided in Chapter 150B of the North Carolina General Statutes by
filing a Petition for a Contested Case Hearing (Petition) with the North Carolina Office of Administrative
Hearings (OAH) within sixty (60) calendar days. Requirements for filing a Petition are set forth in Chapter
150B of the North Carolina General Statutes and Title 26 of the North Carolina Administrative Code.
