Dear Sir:
The North Carolina Department of Transportation (NCDOT) applied for a phased Section 404 Individual
Permit, Section 401 Individual Water Quality Certification (WQC), Neuse River Riparian Buffer
Authorization, Non-404 Jurisdictional Wetlands and Waters Permit for the subject project in September
2018. The project, also known as Complete 540, encompasses three NCDOT Transportation
Improvement Plan (TIP) projects: R-2721 (NC55 Bypass to US-401), R-2828 (east of US-401 to I-40
Interchange) and R-2829 (east of I-40 to US 64/264). Revised permit applications were submitted in
February 2019 and the NCDWR 401 and USACE 404 Permits were issued in February and October of
2019. Additionally, NCDOT received a modified 401 WQC for the Complete 540 Project on January 30,
2020, April 23, 2020, and June 1, 2020 from the NC Division of Water Resources (NCDWR) and a
revised Department of the Army authorization #SAW-2009-02240 on February 7, 2020 and April 29,
2020.
During the final design of the bridges at Permit Site 7 on the R-2721B Section, the Design-Build Team
changed the span arrangement of the mainline bridge from a five span bridge to a three span bridge as
well as the ramp bridge from a five span bridge to a three span bridge. By incorporating these changes
there is a decrease in permanent fill impact by 0.08 acre related to the bridge bents.
Also, during this process the contractor realized that they would need to have additional temporary
impacts in order to build the ramp bridge. The site does not provide enough room for them to move and
place their cranes at the locations required within the currently permitted footprint. To the north side of
the ramp bridge they will need an additional 0.10 acre of temporary impact beyond what was previously
permitted as hand clearing. The area is now shown as temporary impact due to the need for either a
causeway or crane mats. Where possible the contractor would utilize crane mats but this is likely not
possible for the entire area shown as temporary impact. If a causeway or rock placement for leveling the
crane mats is required, then the contractor will have geotextile fabric placed prior to rock being installed
in order to maintain a barrier between the original ground and fill material. This will aid in removal of
the rock.
Similar to the ramp bridge, the mainline bridge was evaluated for construction and the types of impacts
have changed location. The site was previously permitted with a causeway with a number of fingers. The
contractor has realized the fingers would not be necessary; however, temporary impacts would be needed
at different locations to accommodate the cranes and causeway. Temporary impacts are now illustrated
down the center of the alignment, to the outside of the bridge, and along the bridge abutments in order to
have room for movement of the cranes. As stated above, the contractor will utilize crane mats where
possible. Mechanized clearing was able to be reduced slightly. Please note that mechanized clearing is
illustrated on the plans but this area would also be potentially impacted temporarily with the causeway or
crane mats. It was shown as mechanized clearing due to the mitigation requirement for mechanized
clearing as opposed to temporary impacts.
Due to the types of impacts changing location, there will be an increase in temporary impacts of 0.28 acre
which is a change from 0.46 acre to 0.74 acre. There will be a decrease in the hand clearing impacts by
0.09 acre which is a change from 0.55 acre to 0.46 acre. There is a decrease in mechanized clearing of
0.01 acre which is a change from 0.03 acre to 0.02 acre. There is also a decrease in permanent impacts by
0.08 acre for the bridge bents which is a change from 0.20 acres to 0.12 acres of permanent fill. There is
an increase in total impacts at Permit Site 7 by 0.10 acre due to temporary fill impacts replacing hand
clearing, at the request of the USACE, but a decrease in overall project impacts. Please see the enclosed
revised permit drawings and updated impact summary sheets which reflect the changes in impacts.
Revised Impacts Summary R-2721B
Only the jurisdictional wetland impacts have changed in this modification request. The proposed
impacts to jurisdictional wetlands total 12.45 acres of permanent riparian wetland impacts. There will
also be 1.343 acres of temporary wetland impact. This modification request results in changes to Tables
3, 12, and 24 of the previous permit application/modifications. No changes to the other tables were
required so they are not included in this modification request.

Bolded mitigation amounts represent a change from the original issued 404 (SAW-2009-02240)/401 WQC (4179)
and subsequent modifications/revisions.
Currently NCDOT has acquired mitigation for R-2721B from NCDMS to compensate for 14.64 acres of
wetland impacts. The mitigation amount required for this modification, after the changes addressed above,
is 12.45 acres which is below the mitigation acquired by 2.19 acres. Therefore, no other changes to the
required mitigation are necessary due to this modification request.
