SUBJECT: Permit Modification Request for a Nationwide 6 Permit:
US 17 From South of SR 1149 (Price Road) to US 17 South of SR 1536 (Hamilton
Beach Road), Beaufort, North Carolina; TIP Project R-2510B; Federal Aid Project
No. MAF-75-3(26); WBS Element 34440. 1.1
REFERENCE: Nationwide 6 Permit issued May 10, 2005. US Action ID 200510771
Dear Mr. Wescott,
The purpose of this letter is to request a permit modification to the Nationwide 6 Permit issued May
10, 2005. The work detailed below is in addition to the investigation permitted in the above
referenced permit.
As you are aware, The North Carolina Department of Transportation (NCDOT) is planning to build a
bridge on new location within the project limits of the proposed Washington Bypass in Beaufort
County, North Carolina. The proposed bridge will cross the Tar River north of the town of
Washington on NC 17.
The NCDOT Geotechnical Engineering Unit is in the process of coordinating a site characterization
investigation for the revised design of a structure on the above referenced roadway project. The
revised design area is within the wetlands adjacent to the Tar River and Kennedy's Creek. There
will also be three (3) test piles driven in the Tar River.
A private engineering firm (PEF) will be conducting the investigation with I 1 soil borings to be
performed on the project. All of the borings will fall within the footprint of the proposed structure
over the wetlands adjacent to the Tar River and Kennedy's Creek. These locations are shown on the
attached Drawing # 1.

The borings in the wetland will be performed with a low ground pressure tracked drill rig. The land
borings will be 3-inch to 4-inch in diameter. All disturbances from the borings should be limited to
within a 2-foot radius of the boring location. The maximum total amount of ground disturbance
expected for the borings is 140 W.
Three (3) test piles will be driven in the Tar River from a barge and are shown on the attached
Drawing #2. The piles will consist of 30-inch square, precast and prestressed concrete. The test piles
will be driven with no jetting. All piles will be cut off 1 foot below the mudline of the Tar River at
the completion of the test pile program, which would require some disturbance of the riverbed. The
maximum area that may be disturbed from the test pile driving and removal is estimated to be 525
ft
Therefore, the maximum total amount of ground disturbance expected for all of the site
characterization investigation (borings and test pile) is 665 frt.
Because this area is located in sensitive waters, an in-water moratorium exists between February 15
through June 15. All in-stream work will take place outside the moratorium dates.
If you have any questions or would like additional information, please call Mr. Chris Underwood at
[phone]. Thank you in advance for your help in this matter.
Sincerely,
