Eric and Rob,
The Department is currently replacing structures at two sites in Division 5. Bedrock was encountered
within the footprint of the replacement structures at these sites. These sites are discussed bbelow:
Site 1 O(VO 37S-
ReDlacement of structures conveving an unnamed tributarv to Walkers Creek on US 158 in Warren
County.
The Department is currently replacing the structures at this site. The NCDOT applied for permits for
this project on March 3, 2006. Written permits/certifications for this pipe replacement project were
never issued by the regulatory agencies. The project was classified as "exempt" under the riparian
buffer rules.
Bedrock was identified within the footprint of the pipe replacement yesterday. The Department will
place the structure on top of the bedrock and thus will not be buried one foot in the streambed.
Site 2
Replacement of structure conveying an unnamed tributary to Grassy Creek on SR 1323 in Granville
County.
The Department is currently replacing the structure at this site. The NCDOT applied for permits for
this project on March 15, 2006. Written permits/certifications for this pipe replacement project were
never issued by the regulatory agencies. The project is located in the Roanoke River Basin.
Bedrock was identified within the footprint of the pipe replacement yesterday. The Department will
place the structure on top of the, bedrock and thus will not be buried one foot in the streambed
Please contact me if you require additional information about these two projects.

Subject: Proposed maintenance improvements to structures conveying an unnamed
tributary to Walkers Creek on US 158 in Warren County. WBS element
511.109311, STAT 10# 9800766.
The North Carolina Department of Transportation (NCDOT) proposes to replace two
structures conveying an unnamed tributary to Walkers Creek on US 158 in Warren
County (Figures 1 - 2).
Impacts to Waters of the United States
The project crosses a perennial stream, an unnamed tributary to Walkers Creek
[NCDENR-DWQ Index No. 28-79-25-2, Best Usage Classification C NSW; HUC
03020102] (Figure 3) in the Tar-Pamlico River Basin. The existing structures that
convey the creek are 2 @ 54-inch corrugated metal pipes that are 83 feet long with a
headwall at the inlet (see Photographs 1-3).
The proposed structure is a 103-inch x 71-inch corrugated metal pipe arch that is 100-feet
long. Ten feet of rip rap will be placed along the creek banks both upstream and
downstream of the structure. During the construction of the project, the NCDOT
proposes to temporarily dewater the work zone for approximately 2 weeks. This will
involve the temporary placement of sheet piling at the construction limits. To maintain
water flow during construction, water upstream of the sheet piling will be temporarily
pumped out by a hose and conveyed downstream of the construction activity where it will
be allowed to filter through vegetation before flowing into the stream. The effluent from
the work area will be pumped into a prefabricated silt bag allowing water to slowly filter
out of the bag in a dispersed matter and the sediment to be captured in the bag. Once the
stream has been dewatered, the pipes will be replaced. The sheet piling will be removed
after construction.
The existing structures are rusted, undersized, and have resulted in a large blowhole at the
outlet. Please note that the outlet of the proposed structure will be located inside the limits of
Division 5, 2612 N. Duke Street, Durham, NC 27704
Phone: [phone] Fax: [phone]
this ?blowhol(c making it impractical to bury the pipe one foot in the stream bed that now
exists at the bottom of the blowhole. Therefore, NCDOT will set the invert of the pipe one
foot below the "theoretical" streambed elevation taken from projection of the streambed
grade from further down stream back into the blowhole. NCDOT hydraulics unit has
indicated that the increase in diameter of the proposed structure will reduce the water velocity
and cause sediment to accumulate in the blowhole and eventually fill up over time to match
the surrounding stream bed.
Permanent impacts at the site associated with the replacement of the structure involve a total
of 17 feet of surface water fill for installation of the longer structure and the placement of 20
feet of rip rap along the streambanks to protect the structure. Temporary concurrent impacts
will include the dewatering of 37 feet of stream.
Riparian Buffer
Construction at this site involves a road crossing of a stream that is subject to the
Tar-Pamlico River Riparian Buffer Rules. The unnamed tributary to Walkers Creek at Site 1
is depicted on the most recent version of the Macon (USGS 1970) topographic quadrangle
(Figure 1). Construction impacts at this site total 2,504 ft2 in Zone 1 and 0 ft2 in Zone 2
(totaling 37 linear feet of riparian buffer impacts). Please note that impacts associated with
installation of the sheet piling and special stilling basin (silt bag) are included as part of these
totals. Based on the impacts to the riparian buffer at this site, this crossing is EXEMPT.
Waters of the U.S. Mitigation
Avoidance: All wetlands and surface waters not affected by the project will be protected
from unnecessary encroachment. No staging of construction equipment or storage of
construction supplies will be allowed in wetlands or near surface waters.
Minimization: The side slopes have been steepened to the extent possible at jurisdictional
sites. Strict enforcement of sedimentation and erosion control Best Management Practices
for the protection of wetlands and surface waters will be enforced during project
construction. Continued coordination will occur with maintenance forces and the
Environmental Officer during construction to minimize impacts to these sites.
Compensatory Mitigation: All compensatory mitigation requirements will be left to the
discretion of the regulatory review agencies.
Protected Species
Plants and animals with federal classifications of Endangered, Threatened, Proposed
Endangered and Proposed Threatened are protected under provisions of Section 7 and
Section 9 of the Endangered Species Act. As of March 03, 2006, the dwarf wedgemussel
(Alasmidonta heterodon) and the Tar spinymussel (Elliptio steinstansana) are listed as
federally protected species in Warren County. A mussel survey was conducted at this
crossing by biologists with Alderman Environmental Services, Inc. on February 25, 2006
with a finding of no effect for federally protected species. Additionally, a review of the
Natural Heritage Program database (last updated January 2006) revealed no occurrences
of protected species within the project area. Therefore, based on lack of suitable habitat
observed during the site visit and the NHP database review, biological conclusions of No
Effect have been rendered for each species.
Summary
The NCDOT proposes to replace the existing structures with one larger and longer sized
pipe. Permanent impacts at the site associated with the replacement of the structure
involve a total of 17 feet of surface water fill for installation of the longer structure and the
placement of 20 feet of rip rap along the streambanks to protect the structure. Temporary
concurrent impacts will include the dewatering of 37 feet of stream. The sheet piling will be
removed after construction. Riparian buffer impacts at Site 1 associated with this
maintenance activity total 2,504 ft2 in Zone 1 and 0 ft2 in Zone 2 (totaling 37 linear feet
of riparian buffer impacts). Based on the impacts to the riparian buffer at this site, this
crossing is EXEMPT.
Application is hereby made for a Department of the Army Section 404 Nationwide
Permit (NWP) 3, NWP 33, and NCDENR-DWQ Section 401 Water Quality Certification
(WQC) No. 3494, WQC No. 3366, and riparian buffer authorization for above-described
activities. An automated payment procedure has been implemented between the NCDOT
and NCDENR-DWQ. This procedure will enable the Division to apply for the 401 WQC
without submitting a check for this permit application. This procedure will provide
payment to the NCDENR-DWQ by charging the permit application fee of $200.00
directly to the appropriate NCDOT WBS element 513.109311, STAT IO# 9800766. A
pre-construction notification is attached with this request. If you have any questions or
need additional information, please contact Mr. Chris Murray at [phone].

financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. All wetlands and surface
waters not affected by construction will be protected from unnecessary encroachment during
construction. Strict enforcement of Best Management Practices for the protection of wetlands
and surface waters will be enforced during construction. Only the smallest amount of fill
necessary to complete the project will be placed in waters of the United States.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
Page 5 of 8
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
httl2:Hh2o.enr.state.ne.us/ncwetlands/strmgide.litml.
