Subject: Request for Modification of 404 Individual Permit, 401 Water Quality
Certification Permit, Tar-Pamlico Buffer Authorization, and CAMA Major
Development Permit for the proposed Washington Bypass. US 17 From South
of SR 1149 (Price Road) to North of SR 1509 (Springs Road). TIP Number: R-
2510B, Federal Aid Project MAF-75-3(26). Debit $475 for WOC Modification
from WBS Element No. 34440. 1.1
Reference: USACE Action ID 199301143
DWQ Project No. 050785, WQC No. 3527
CAMA Permit No. 29-07
The North Carolina Department of Transportation (NCDOT) is requesting a modification to the
above referenced permits for wetland impacts and a change in buffer accounting associated with
R-251013. Included in this package are the following: revised wetland impacts, Tar-Pamlico
Riparian Buffer impacts, revised permit drawings and revised buffer drawings.
The revised design does not compromise NCDOT's compliance with the existing permit
conditions. The revision has been evaluated for compliance with the avoidance/minimization
criteria and is in compliance with all previous issues, including the following:
• Protected Species
• Aquatic Life passage
• FEMA compliance
• Cultural Resources
Summary of Chanzes
This application addresses impacts at Sites 4 and 9. There is no change in the amount of wetland
impacts, however, there is a change to the types of impacts. Excavation in wetlands has increased
by 0.03 acre and mechanized clearing has decreased by 0.03 acre. There is an increase of 1,522

sq. ft. of Tar-Pamlico Riparian Buffer impacts due to the wetlands no longer being jurisdictional.
However, the area is accounted for as buffer impacts.
General Project Description
The NCDOT proposes to improve existing US 17 to a high speed, multi-lane highway that
bypasses the City of Washington. R-2510B will include the widening of approximately 6.8 miles
of US 17 from south of SR 1149 (Price Road) south of Chocowinity to North of SR 1509
(Springs Road) north of Washington. The proposed roadway will be a four-lane, divided
highway, with grass shoulders and ditches, and a 46-foot wide grassed median.
Impacts to Waters of the U.S.
Proposed impacts to jurisdictional areas of R-2510B consist of 7.92 acres of wetlands (6.04 acres
of riverine and 1.88 acres of non-riverine), 0.38 acre of surface waters, and 2,368 feet of streams.
There are no additional proposed impacts. There is only a change in the type of wetland impacts.
Tar-Pamlico Buffer Impacts
The total Tar-Pamlico riparian buffer impacts associated with R-2510B are unchanged and
consist of 230,368 sq. ft. in Zone 1 with 174,526 sq. ft. which are allowable with mitigation due
to roadway fill and 142,372 sq. ft. in Zone 2 with 111,225 sq. ft. which are allowable with
mitigation due to roadway fill. What has changed is the amount of wetlands within the riparian
buffer due to the removal of jurisdictional status of the stormwater pond at Site 9. Zone 1
impacts requiring mitigation increased by 355 sq. ft. and Zone 2 impacts increased by 1,167 sq.
ft.
PERMITTING ACTIVITY TO DATE
Clean Water Act Section 404 Individual Permit
The project received a Clean Water Act Section 404 Individual Permit (Action ID # 199301143)
from the U.S. Army Corps of Engineers (USACE) Wilmington District on November 28, 2005.
This permit authorized construction for Section R-2510A. A modification dated January 17,
2007 to the permit was received by NCDOT.
Section 401 Water_ Ouality Certification
The project received a Section 401 Water Quality Certification (DWQ Project No. 050785, WQC
No. 3527) from the North Carolina Department of Environment and Natural Resources, Division
of Water Quality (NCDWQ) on September 6, 2005. A modification dated February 13, 2007
was received by NCDOT.
Tar-Pamlico Riparian Buffer Authorization
The project received a Tar-Pamlico Riparian Buffer Authorization (DWQ Project No. 050785,
WQC No. 3527) from the North Carolina Department of Environment and Natural Resources,
Division of Water Quality (NCDWQ) on September 6, 2005. A modification dated February 13,
2007 was received by NCDOT.
Coastal Area Management Act (CAMA) Consistency Certification and CAMA Maior
Permit
A Consistency Certification was issued by North Carolina Department of Environment and
Natural Resources Division of Coastal Management on October 31, 2005 for the entire R-2510
project and a CAMA Major Development Permit was issued on March 6, 2007 for R-2510B.

MITIGATION
Jurisdictional Wetland Mitigation: NCDOT does not propose mitigation for these impacts due to
there being no net change in permanent wetland impacts.
Tar-Pamlico Buffer Mitigation: NCDOT proposes to use the North Carolina Ecosystem
Enhancement Program (EEP) to mitigate for permanent impacts associated with this project. The
attached EEP request has been forwarded to EEP. A copy of the EEP acceptance letter will be
forwarded when received.
REGULATORY APPROVALS
The NCDOT respectfully requests that the referenced Section 404 Permit be modified to reflect
the changes in jurisdictional impacts as outlined in this letter and presented in the attached
drawings. The NCDOT is also requesting a modification to the 401 Water Quality Certification
and Tar-Pamlico Buffer Authorization from the NCDWQ. In compliance with Section 143-
215.3D(e) of the NCAC, we have provided a method of debiting $475, as noted in the subject
line of this application, as payment for processing the Section 401 permit modification
application. We are providing five copies of this modification application to the NCDWQ for
their review and approval. The NCDOT respectfully requests that the referenced CAMA Major
Development Permit be modified to reflect the changes in jurisdictional impacts as outlined in
this letter and presented in the attached drawings. Please find the attached updated permit
drawings.
If you have any questions or need additional information, please call Mr. Chris Underwood at
[phone].
