Attention: Mr. Tom Steffens
NCDOT Coordinator
Dear Sir:
ANTHONY J. TATA
SECRETARY
Subject: Permit Modification Request for Section 404 Nationwide 23, Section 401
Water Quality Certification and Tar - Pamlico Buffer Authorization for the
construction of a new rest area along US 17 near Chocowinity in Beaufort
County; TIP Project K -3800; Federal Project No. NHS - 17(32); WBS No.
38748.1.1.
References: Permit application dated 6/19/2013, Permit modification request dated 3/13/14
404 issued 11/13/13, Action Id. SAW- 2013 -02202
401 issued 8/9/13, DWR Project No. 20130649.
The North Carolina Department of Transportation ( NCDOT) applied for permit authorizations
for the subject project on June 19, 2013. This application indicated that there were no expected
impacts to streams or buffers due to utilities. Modifications have been made to the utility plans
for the project which now involve installation of a 6" water line, which will increase impacts to
buffer zones 1 and 2. NCDOT requested a modification to the permits to account for these
additional impacts on March 13, 2014. Following additional coordination, the project plans have
been further revised. The water line will now be installed by a directional bore method. The
change to directional bore methods eliminated the utility impacts proposed in our March 13
permit modification request.
As a result of the stream's jurisdictional starting point now at the pipe outfall, additional stream
impacts (Site 3) and buffer impacts (Site 4) are now proposed. Buffer Site 4 will have impacts
to buffers in both Zone 1 and Zone 2:
Site
I Zone 1 (sq. ft.)
Zone 2 (sq. ft.)

This increases the overall project buffer impacts to a total of 12,935 sq. ft. in Zone 1 and 9,291
sq. ft. in Zone 2, totaling 22,226 sq. ft. of buffer impacts for the project. Permanent stream
impacts have also increased by 27 ft now totaling 296 ft. Revised permit drawings are included
with this modification request.
The additional mitigation required for these new impacts can be accommodated by the onsite
mitigation plan, so no changes to the mitigation proposal are anticipated. An updated copy of the
US 17 Rest Area K -3800 debit ledger is included with this modification request.
