Road: SR 1003 (Eagle Rock Road)
County: Wake
River Basin: Neuse
Stream Name: UT to Buffalo Creek
Lat, Long: N35.78071, W78.40196
HUC: 030202011502
NCDENR-DWQ Index Number, Stream Classification: 27-57-16-(2); B; NSW
Existing structure: 48" diameter corrugated metal pipe that is 48ft in length.
Proposed structure: Replace with a 72" diameter aluminum pipe. This new structure is 55ft
long with a headwall and sill. Rip rap will be installed underlined with geotextile for long
term stability surrounding the tie-ins to the headwall and existing banks.
Riparian Buffers: Equipment used and work performed will be from the existing
transportation facility. Foot traffic access for installation of temporary dewatering measures
will be limited just upstream and downstream of the pipe replacement to maintain a dry
work area. No trees will be cut and no grading within riparian areas is proposed. Therefore,
no Neuse Buffer impacts are proposed.
Temporary impacts: +/-10ft dewatering (5ft below pipe outlet and 5ft above pipe inlet). If
necessary, impervious dikes will be installed in the streambed upstream and downstream of
the work site for containment and to maintain a dry work area. A clean water pump around
will be used to maintain a dry work area. Impervious dike materials will be removed once
the work is complete.
Permanent impacts: 7ft of fill in surface water is proposed with the longer pipe in addition
to +/-5ft of rip rap on stream banks upstream and 5ft downstream.
Wetland Information: Although this crossing is mapped as having hydric soils (HeB-Helena
Sandy Loam, undrained), there are no wetlands within the construction footprint.
Cultural Resources: Review of the SHPO GIS mapping reveals no cultural resources, no
historic structures nor properties at this crossing.

Protected species information:
Michaux's Sumac: Biological Conclusion of No Effect was rendered based on lack of suitable
habitat within the highly maintained shoulders and roadway slopes.
Red -Cockaded Woodpecker: BC of No Effect based on lack of habitat with non -forested
roadway shoulders and fill slopes.
Carolina Madtom: A US Fish and Wildlife Service (USFWS) proposal for listing the Carolina
Madtom (Noturusfuriosus) as a threatened species was published in the Federal Register in
May 22, 2019. The listing will likely become effective by May 22, 2020. Furthermore, this
species is included in USFWS' current list of protected species for Wake County. It is
anticipated that this project will be completed before this species becomes officially listed.
However if not, consultation with the USFWS regarding Carolina Madtom will be addressed
when this species becomes listed.
Neuse River Waterdog: A US Fish and Wildlife Service (USFWS) proposal for listing the
Neuse River Waterdog (Necturus lewisi) as a threatened species was published in the
Federal Register in May 22, 2019. The listing will likely become effective by May 22, 2020.
Furthermore, this species is included in USFWS' current list of protected species for Wake
County. It is anticipated that this project will be completed before this species becomes
officially listed. However if not, consultation with the USFWS regarding Neuse River
Waterdog will be addressed when this species becomes listed.
Dwarf wedgemussel: Use of the Programmatic Biological Opinion for Culvert Replacements
and Extensions in Eastern North Carolina, NCDOT Divisions 1-8 (June 13, 2018) provides a
Biological Conclusion of May Affect -Not Likely to Adversely Affect for this species.
Tar River spinymussel: Use of the Programmatic Biological Opinion for Culvert
Replacements and Extensions in Eastern North Carolina, NCDOT Divisions 1-8 (June 13,

species.
Yellow lance: Use of the Programmatic Biological Opinion for Culvert Replacements and
Extensions in Eastern North Carolina, NCDOT Divisions 1-8 (June 13, 2018) provides a
Biological Conclusion of May Affect -Not Likely to Adversely Affect for this species.

NATIONWIDE PERMIT 3
DEPARTMENT OF THE ARMY
CORPS OF ENGINEERS
FINAL NOTICE OF ISSUANCE AND MODIFICATION OF NATIONWIDE PERMITS
FEDERAL REGISTER
AUTHORIZED MARCH 19, 2017
Maintenance. (a) The repair, rehabilitation, or replacement of any previously authorized,
currently serviceable structure or fill, or of any currently serviceable structure or fill authorized
by 33 CFR 330.3, provided that the structure or fill is not to be put to uses differing from those
uses specified or contemplated for it in the original permit or the most recently authorized
modification. Minor deviations in the structure's configuration or filled area, including those
due to changes in materials, construction techniques, requirements of other regulatory
agencies, or current construction codes or safety standards that are necessary to make the
repair, rehabilitation, or replacement are authorized. This NWP also authorizes the removal of
previously authorized structures or fills. Any stream channel modification is limited to the
minimum necessary for the repair, rehabilitation, or replacement of the structure or fill; such
modifications, including the removal of material from the stream channel, must be
immediately adjacent to the project. This NWP also authorizes the removal of accumulated
sediment and debris within, and in the immediate vicinity of, the structure or fill. This NWP
also authorizes the repair, rehabilitation, or replacement of those structures or fills destroyed or
damaged by storms, floods, fire or other discrete events, provided the repair, rehabilitation, or
replacement is commenced, or is under contract to commence, within two years of the date of
their destruction or damage. In cases of catastrophic events, such as hurricanes or tornadoes,
this two-year limit may be waived by the district engineer, provided the permittee can
demonstrate funding, contract, or other similar delays.
(b) This NWP also authorizes the removal of accumulated sediments and debris
outside the immediate vicinity of existing structures (e.g., bridges, culverted road crossings,
water intake structures, etc.). The removal of sediment is limited to the minimum necessary to
restore the waterway in the vicinity of the structure to the approximate dimensions that existed
when the structure was built, but cannot extend farther than 200 feet in any direction from the
structure. This 200 foot limit does not apply to maintenance dredging to remove accumulated
sediments blocking or restricting outfall and intake structures or to maintenance dredging to
remove accumulated sediments from canals associated with outfall and intake structures. All
dredged or excavated materials must be deposited and retained in an area that has no waters of
the United States unless otherwise specifically approved by the district engineer under separate
authorization.
(c) This NWP also authorizes temporary structures, fills, and work, including the use of
temporary mats, necessary to conduct the maintenance activity. Appropriate measures must be
taken to maintain normal downstream flows and minimize flooding to the maximum extent
practicable, when temporary structures, work, and discharges, including cofferdams, are
necessary for construction activities, access fills, or dewatering of construction sites.
Temporary fills must consist of materials, and be placed in a manner, that will not be eroded by
expected high flows. After conducting the maintenance activity, temporary fills must be
