Karina,
As noted in your email of November 3, 2023 (below), NCDOT requests authorization to install two
temporary pipes on the HE-0001 to aid in construction of the project. The first temporary pipe would
be located in the footprint of an already authorized, permanent impact and the other temporary pipe
would be located in the footprint of the clean water diversion that is shown in the EC plans.
I coordinated this request with DWR, USFWS, and WRC on November 6, 2023. All three agencies
responded with no objections. NCDWR noted the following: "I do not see any issues with what they
are proposing as long as the footprint of the approved impacts don't change and they follow the
conditions of the 401 Water Quality Certification."
The USACE does not object to this modification if the work is conducted in accordance with (1) the
description of work in your email of November 3, 2023, to include the attached plans, and (2) all
general and special of the Section 404 permit for this project. As such, by this email NCDOT is
authorized to conduct work in waters of the U.S. as proposed.
Please let me know if you have any questions.
Thank you,
Lori

Subject: [Non-DoD Source] HE-0001 Modification request

Good afternoon Lori,
This project, Action ID SAW-2021-0535 (STIP Project No. HE-0001), would like to request authorization to
allow installation of a stream crossing that will be needed to reach the east side of the stream. Previously
at the environmental preconstruction meeting, details of the proposed temporary stream crossing to support the
clearing/grubbing operation was discussed. Attached is a redlined plan sheet that shows the approximate
location and the standard drawing for the crossing. The proposed location is within the limits of the permanently
impacted jurisdictional stream for the HE-0001 construction work. Special Condition 20 of the permit describes
the use of a temporary crossing during the clearing operation. The reason for this request is due to the need to
reach the east side of the stream for clearing/grubbing operations.
It is also proposed to allow the installation of a temporary pipe in lieu of the clean water diversion that is shown
in the EC plans, please see the attached PNG file. The reason for this request is due to the contractor stating that
a clean water diversion would most likely not be sufficient to appropriately divert the JS. The footprint of this
proposed temporary pipe is within that of the diversion.
Thank you for your attention to this matter. Please don't hesitate to reach out if you have any questions or need
anything else.
Thank you,
