I had sent the plans that were provided to you all on Monday to the USACE for approval of the
temporary bottom disposal area prior to finalizing them and distributing. I received verbal
confirmation that the USACE Navigation Branch was comfortable with the location that was shown
on the plans dated 11-26-18. However, based on updated conditions, the dredge operator has
requested the area be moved approximately 300 feet to the west to better align with deep water.

The attached pdf from the USACE"RC_05_HST_20181025_CS_QTY_3.pdf" shows the updated
location recommended by the dredge operator.
Please let me know if you have any questions.

Please see attached updated drawings for the upcoming Hatteras Inlet dredge project. The drawings
include updated bathymetric data and a slightly modified channel location from the one provided to
you as part of the written notice dated 10/23/2018 (DCM) and 10/24/18 (USACE).
At present, the USACE is scheduled to begin dredging sometime Thursday. They have informed us
that in fact they anticipate using the temporary bottom disposal area previously approved but not
used. The temporary bottom disposal area is shown on Sheet 3 of the attached drawings.
Please let us know if you have any questions about the plan for the upcoming Hatteras Inlet
dredging.

I spoke with Heather Coats this morning about updates on the Hatteras Inlet Project. There have
been some delays associated with the process to transfer funds between the project partners. At
present, the earliest we believe the dredging might occur would be November 28th; however, that
may be a long shot.
We are working on updating the drawings we provided prior to the October 30 pre -con meeting
given the new survey conducted by the USACE on October 25. We should have those drawings to
you early next week.
Also, during the meeting there was discussion about a 1 time in -water temporary disposal of dredge
material to allow for more efficient dredging. This method was authorized for a one time use by the
modified CAMA Permit issued March 14, 2018. 1 believe a similar allowance was granted by the
USACE. The CAMA Permit Language reads:
This permit modification authorizes the one time use of an in -water temporary disposal site as
depicted in the attached email correspondence dated 2/28/18 and work plan drawing dated

2/15/18. This one time in -water temporary disposal is authorized for a maximum volume of 500 cy.
Spoil must be transported to the authorized offshore disposal site once the shoal is to an acceptable
depth for safe dredge operations.
Please note that after discussing the proposed operations with USACE Navigation Branch staff, we
do anticipate that this method may be needed for the upcoming maintenance event. Please also
note that the one time authorization to use in -water temporary disposal was not used during the
last event as it was not needed. We are requesting that if such a method is needed during this
upcoming event, that we can use the previous authorization to cover the action. We will indicate
the temporary disposal area in the drawings we provide next week.
If you have any questions, please feel free to reach out to me. I'll be in the office all day on Tuesday,
but out the rest of the week for Thanksgiving.
