Amy, since the waters north of the bridge are designated inland waters, I will defer the ultimate decision-making
to Travis. However, after April 1, the limited impact to anadromous fishes would not cause any objection from
DMF.

Hi Curtis,
It will take approximately 4 weeks to collect all the borings. The borings will be advanced using the mud rotary
method. This involves setting a piece of 4" or 6" diameter casing between the drill rig on the barge and the river
bed to contain the drilling fluid and cutting returns. The drilling itself is rotational, but it is encased. The soil
samples are collected by hammering a sampler at specified intervals. All soil samples, drilling fluid and cutting
returns are disposed off-site.
Let me know if you need more info.

Hey Amy,
How long do you anticipate the borings will take to collect and how will they be collected? i.e. vibration,
rotational, impact hammer etc?

NCDOT is proposing to replace bridge no. 7 on NC 24 over Northeast Creek in Onslow County as part of TIP U-
5741. In order to determine what sort of bents will be used in the design, approximately seven geotechnical
borings (3.5 inches in diameter) need to be taken from the streambed (see attached). This crossing forms the
boundary between coastal and inland waters and is subject to a Primary Nursery Area moratorium between Feb.
1 and Sept. 30. Due to the minimal in-water impact from this activity, NCDOT is requesting to complete this work
during the moratorium period. All work will be done from a barge.
If you have questions or concerns before providing a decision, please let us know.
Thanks,
Amy

Geotech borings have typically been allowed during the moratorium.
