Attn: Ms. Kim Garvey

Dear Ms Garvey:
Subject: Application for Modification to Section 404 and Section 401 permits for the US
421/NC 87 (Sanford Bypass) from east of NC 42 to NC 87 near SR 1138 in Lee County,
Division 8. Federal Aid Project No. STPNHF-421(2), State Project No. 8.T540402,
WBS Element No. 34431.1.6, TIP No. R-2417C.
References: Section 404 Individual Permit Modification, issued March 25, 2009, USACE Action ID
2002-2-0899.
Section 401 Individual Water Quality Certification (Sixth modification), issued January
21, 2009, NCDENR-DWQ Water Quality Certification Project No. 001432.
Section 404 Individual Permit, issued May 28, 2002, USACE Action ID 2002-2-0899.
Section 401 Individual Water Quality Certification, issued April 10, 2002, Project No.
001432.
The North Carolina Department of Transportation (NCDOT) proposes to construct a four-lane median
divided freeway with full control access, on new location to serve as a US 421INC 87 bypass of Sanford,
North Carolina. The purpose of this submittal is to request another modification to the Section 404
permit and Section 401 Water Quality Certification for R-2417C. Please see the enclosed copies of the
revised permit drawing sheets 20 - 23 of 31, revised summary tables (revised permit drawing sheets 4-8
of 31), and a copy of the EEP letter for the above-referenced project.
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:

Site 5 Station 87+90(LT/RT)
The nylon net matting has been removed from the channel Although the pipe was initially
installed properly at the correct invert of 1 foot below stream bed level subsequent work for
grading and stabilization along the bank and in the channel by the subcontractor caused the
pipe to become perched Additional grading work by the subcontractor has also impacted
the stream from the permitted areas at both ends of the pipe out to the right of way limits
(both ends) NCDOT has tentatively proposed that a series of log cross veins be installed to
restore the proper invert of one foot below bed level by using the logs as grade control
devices to raise the stream bed and then to gradually lower it back to the natural level as the
cross veins progress downstream by lowering each subsequent vein by 8 inches It is
possible that the depth to rock at this location may make this repair impractical As was
/' /discussed during a phone conversation between Art King Division 8 DEO and Mason
Herndon DWQ we may need to revisit this site at a future date after we have had a chance
to observe the effects of flow through the site As you are aware this channel has
intermittent flow limited primarily to rainfall events
The actions above will cause an additional 50 feet of temporary stream impacts at Site 5 (30
feet upstream, and 20 feet downstream) to cover the areas impacted between the temporarily
impacted area denoted in the plans on both ends of the pipe out to the right of way limits
Site 6 Station 120+20(LT) and 120+57(LT/RT)
An approved temporary stream crossing plan drawing was included in the construction plans
(Sheet EC 2D) This plan is suitable for a crossing that does not require that flow be
maintained by simply removing the pipe This plan was not followed by the contractor at
this location Instead an earthen dike without a fabric liner was placed in the dewatered
stream channel between the diversion device and the upstream end of the newly constructed
culvert by the contractor This area was used as a crossing point to move equipment around
the culvert during construction We acknowledge that the crossing was improperly installed
and has impacted the existing stream channel
The actions above will be an additional 30 feet of temporary stream impacts The earthen
dike will be removed and the channel will be restored to its original contours re vegetated
and allowed to stabilize before the stream is turned into the new culvert
Site 9 Station 178+82(RT)
Approximately 10 feet of the original stream channel was filled with an earthen dike by the
contractor as a means to move his equipment around the culvert structure
The actions above will be an additional 10 feet of temporary stream impacts The earthen
dike will be removed and the channel will be restored to its original contours re vegetated
and allowed to stabilize before the stream is turned into the new culvert
There will be a total of 90 additional feet of temporary stream impacts from this permit
modification
2

Changes in impacts are due to the proposed service road extension since the permit modification issued
March 25, 2009 (see enclosed revised permit drawings). The proposed service road is to be extended
from permit drawing sheet 20 of 31 (cul-de-sac in March 25, 2009 permit modification) and end at
revised permit drawing sheet 22 of 31 near the pond at Site 10. The reason for the service road extension
is to provide access to a large parcel of land (Thomas property) as a result of recent right-of-way
negotiations.
Changes in impacts occur at Site 9 resulting in an increase of 0.04 acres of permanent wetland (riparian)
fill (totaling 0.15 acres) compared to the permit modification issued March 25, 2009 (0.11 acres). Please
refer to the enclosed revised summary tables for details.
A copy of the permit modification with these revisions will be posted on the NCDOT website at:
http://www.ncdot.org/doh/preconstruct/pe/. If you have any questions or need additional information,
please call Greg Price at [phone].
