NCDWR Project # 07-1093 (VA - V.5)
WR Project #02061345.09
Dear Ms. Alexander and Ms. Higgins,
On behalf of the City of Raleigh Public Utility Department, WithersRavenel is requesting
authorization from the USACE to use NWP 33 for 0.82 acres of temporary wetland impacts
associated with the abandonment of an old sewer line within wetlands north of Raleigh Blvd. We
are also requesting a 401 WQC from NCDWR for the above referenced impacts.
The project consists of temporary access along ±900 If of existing sewer line in order to demolish
the existing manholes and properly abandon the sewer line. The project area is located within a
large herbaceous/shrub wetland north of the intersection of Raleigh Blvd and Crabtree Blvd in
Raleigh, Wake County (Latitude: 35.807609°N; Longitude: -78.607958°W). The project is located
in the Neuse River basin (BUC 03020201) and drains to Crabtree Creek. The Water Quality
Classification for Crabtree Creek is C; NSW and the Stream Index Number is: 27-33-(10).
Proposed Project
The proposed project consists of the temporary wetland impacts needed in order to access the
existing manholes for demolition and proper abandonment of the sewer line. The sewer line to be
abandoned is no longer needed, as the new Crabtree Creek North Bank Interceptor sewer line
currently being constructed to the west will eliminate flow to this line. Per the City of Raleigh
requirements, the existing sewer line must be abandoned once the new sewer is put into service.
The abandonment will consist of demolishing the existing manholes to ±18 inches below the pond
bottom and then grouting the manholes to permanent plug them.
The abandonment procedure will consist of accessing the easement to existing MH 103 and MH
102 from the existing greenway trail near existing MH 104. Due to the soft and wet conditions,

wooden mats will be placed and used to allow tracked excavators to traverse the easement to each
of the existing manholes. Existing trees and brush within the easement will be mowed to ground
level leaving the stumps in place using a grinder attachment on a track excavator. The vegetation
will only be removed that is necessary to gain access and remain within the existing easement. Once
MH 103 is accessed, the manhole will be demolished by removing the block top by hand and with
the assistance of track excavator and access the MH to place the grout and block plugs in either side
of the line as directed and detailed in the plans. Materials needed to plug the line and materials from
the demoed MH will be hauled out by a track truck with low ground pressure on placed mats. When
the removal of MH 103 is completed as per plan, access will continue to MH 102 with the same
process as listed above. Upon completion, the area that has been cleared that is not underwater
will be seeded with the approved wetland seeding detailed in the specifications.
Project History
The proposed sewer abandonment is the final phase of the Crabtree Creek North Bank Interceptor
Rehab project, which was originally issued a NWP 12 in 2011, and has received subsequent re -
authorizations in 2013 & 2015 (AID: SAW -200801253). The proposed temporary wetland impacts
for the sewer abandonment was not included in the NWP 12 issued in 2015.
Proposed Impacts
The proposed impacts consist of 0.82 acres of temporary wetland impacts necessary for temporary
access along the sewer easement in order to demolish the manholes and properly abandon the old
sewer line once it's taken out of service.
Please note that the proposed project area is outside of the 50' Neuse River Riparian Buffer
associated with Crabtree Creek, which is located west of the proposed project area. Therefore,
there will be no impacts to riparian buffers associated with the proposed project.
Avoidance and Minimization
As a result of the existing sewer line to be abandoned being located entirely within wetlands,
impacts could not be avoided. Impacts will be minimized by mowing vegetation within the
temporary access corridor, which will allow rapid regeneration of vegetation once the project is
complete. Additionally, wooden mats will be placed within the temporary access corridor to
minimize disturbance from equipment, and all mats will be removed once the project is complete.
Additionally, all cleared areas that are not under water will be seeded with a wetland seed mix to
provide stabilization. Once the sewer is appropriately abandoned, the easement will be allowed to
re -vegetate and will never be disturbed again.
Wetland Mitigation
The proposed wetland impacts are temporary, and therefore mitigation is not proposed.

RE: CCNBI Sewer - Raleigh Blvd Sewer Abandonment; 02061345.09
Dear Troy Beasley:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information
about natural heritage resources from our database that have been compiled for the project referenced
above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, or conservation/managed areas within the proposed project boundary submitted
with your request for information. These results are presented in the attached `Documented Occurrences'
table and map.
Also attached is a table summarizing rare species and natural communities that have been documented
within a one -mile radius of the project boundary. The proximity of these records suggests that these natural
heritage elements may potentially be present in the project area if suitable habitat exists and is included for
reference. In the event that rare species are found within the project area, please contact the NCNHP so that
we may update our records. Tables of natural areas and conservation/managed area within a one -mile
radius, if any, are also included in this report.
Please note that natural heritage element data are maintained for the purposes of conservation planning,
project review, and scientific research, and are not intended for use as the primary criteria for regulatory
decisions. Information provided by the NCNHP database may not be published without prior written
notification to the NCNHP, and the NCNHP must be credited as an information source in these publications.
Maps of NC Natural Heritage Program data may not be redistributed without permission from the NCNHP.
Also please note that the NC Natural Heritage Program may follow this letter with additional correspondence
if a Dedicated Nature Preserve (DNP), Registered Heritage Area (RHA), or an occurrence of a Federally -
listed species is documented within or near the project area.
Thank you for your inquiry. If you have questions regarding the information provided in this letter or need
additional assistance, please contact John Finnegan at john.finneganancdcr.gov or 919.707.8630.
Sincerely,
NC Natural Heritage Program

No Element Occurrences are Documented within the Project Area
There are no documented element occurrences (of medium to very high accuracy) that intersect with the project area. Please note, however, that although the NCNHP database
does not show records for rare species within the project area, it does not necessarily mean that they are not present; it may simply mean that the area has not been surveyed. The
use of Natural Heritage Program data should not be substituted for actual field surveys if needed, particularly if the project area contains suitable habitat for rare species. If rare
species are found, the NCNHP would appreciate receiving this information so that we may update our database.

Determination of Minor Construction Activity
North Carolina Division of Water Quality
Construction Grants and Loans Section
Project Applicant: City of Raleigh
Date: July 20, 2010
Project Number: CS370419-13
Estimated Project Cost: $14,100,000
Estimated Funding Amount: $1.3,459,273
Project Description: The proposed project will provide new 36 -inch replacement pipe and 5 -foot
diameter precast manholes from the downstream end of the project at Raleigh Boulevard
upstream to the I-440 Beltline, using conventional dig and replace methods. In some areas, such
as the orphan landfill area; existing railroad and roadway bore and jack crossings; and deep cut
areas where replacement is not feasible, portions of the 36 -inch and all of the 30 -inch pipe will
be rehabilitated by internal reconstruction methods. The project corridor remains the same as
that approved in the 2006 Preliminary Engineering Report. This environmental document
supersedes the original Finding of No Significant Impact dated January 19, 2007.
The above named applicant intends to apply for assistance from the State Revolving Fund
program to construct the wastewater facilities described above. The North Carolina Division of
Water Quality (DWQ) has conducted a review of the project in accordance with the procedures
(NCAC 15A Subchapter 1C) for conformance with the North Carolina Environmental Policy
Act. The DWQ has determined that this amended project is a minor construction activity, and
that the preparation of additional environmental documents is not required.
This determination shall become effective upon its distribution by DWQ and a one-time
publication of this determination by the applicant in a newspaper having local circulation. This
determination can be revoked at any time adverse information is made available. The
documentation to support this decision will be on file with the North Carolina Department of
Environment and Natural Resources, Division of Water Quality, Construction Grants and Loans
Section, and is available for public scrutiny upon request.
Comments concerning this decision may be addressed to Ms. Jennifer Haynie, Facility
Evaluation Unit, Construction Grants and Loans Section, Division of Water Quality, 1633 Mail
Service Center, Raleigh, North Carolina 27699, or she can be reached by phone at (919) 715-
