An additional 20 linear feet of temporary stream impacts occurred at Site 18 (culvert 5) due to the addition of a temporary
diversion outlet.
On the downstream side of culvert 5 at Site 18 a temporary pipe and impervious dike are needed to route drainage from
adjacent wetland WT. Additionally, 24 inch pipes will be used for diversions during the construction sequence in lieu of
diversion ditches.

This in -field modification is required for the following reason(s):
The information contained in the application or presented in support thereof is incorrect in the
following manner:
Lx Conditions under which the original certification was issued have changed in the following manner:
Temporary stream impacts are needed during the construction sequence of culvert 5 at Site 18.
This in -field modification is valid only if issued by an authorized agent of the Division of Water Resources,
Transportation Permitting Unit'
This in -field modification authorizes the NCDOT to
to temporarily impact an additional 20 linear feet of stream at Site 5 and use diversion pipes in lieu of diversion
ditches during the construction of culvert 5
in Craven County. The project shall be constructed as described in the Modification
Description and Sketch on Page 1 of this document dated 11/9/2023 to improve/construct the
culvert at Site 18. The approved design is that described in the Modification Description and Modification
Sketch on Page 1 of this document dated 11/9/2023. Any further changes to the original Water Quality
Certification dated January 15, 2021_may require a formal written modification request.
The description of the proposed action provides adequate assurance that the proposed action in the
Neuse River Basin in conjunction with the proposed development will not result in a violation of applicable
Water Quality Standards and discharge guidelines. Therefore, the State of North Carolina certifies that
this activity will not violate the applicable portions of Section 301, 302, 303, 306, 307 of PL 92-500 and PL
95-217 if conducted in accordance with the application and conditions hereinafter set forth. Should your
project change, you are required to notify the DWR and submit a new application. If the property is sold,
the new owner must be given a copy of this Certification and approval letter and is thereby responsible for
complying with all conditions. For this approval to remain valid, you are required to comply with all the
conditions listed below. In addition, you should obtain all other federal, state, or local permits before
proceeding with your project including (but not limited to) Sediment and Erosion control, Coastal
Stormwater, Non -discharge and Water Supply watershed regulations. This Modification Approval shall
expire on the same day as the expiration date of the corresponding Corps of Engineers Permit.
Conditions(s) of Modification Approval:
1. All the authorized action activities and conditions of the certification associated with the original
Water Quality Certification dated January 15, 2021 and all other corresponding modifications still
apply except where superseded by this certification.
2. Additional Conditions:

Failure to construct the proposed action as described in the Modification Description and Sketch on
Page 1 of this document and/or violations of any condition herein set forth may result in revocation of this
modification approval and may result in criminal and/or civil penalties. This modification approval shall
become null and void unless the above conditions are made conditions of the Federal 404 and/or Coastal
Area Management Act Permit. If the Corps of Engineers requires a formal written modification to the 404
permit for the proposed action, the NC DWR must require a formal written modification to the 401 WQC,
and therefore, this in -field modification is invalid. If additional (wetland, stream, buffer) impacts for this
project (now or in the future) exceed (one tenth of one acre, 300 linear feet, or one-third of an
acre/150 linear feet, respectively), or if mitigation is required above and beyond the current mitigation
requirement for this project, this in -field modification is invalid and a formal written modification is
required.
This in -field modification is effective upon the date the last party signs this document. This in -field
modification is made upon mutual agreement between DOT and DWR as indicated by the signatures
below and is, therefore, not subject to appeal by either party. Appeals by third parties must be made
within sixty (60) days of notification pursuant to the contested case provisions of the Administrative
Procedure Act, NC Gen. Stat. §150B-23 et seq.
