NCDWQ Section 401 Major WQC Project No. 2007-71470, issued
March 17, 2008
The North Carolina Turnpike Authority (NCTA), in coordination with the North
Carolina Department of Transportation (NCDOT), is currently constructing a 12.6-
mile long, new location roadway (Western Wake Freeway) on the western side of
Wake County, North Carolina. The NCTA submitted an Individual Section 404 (of
the Clean Water Act) Permit Application to the U.S. Army Corps of Engineers
(USACE) for the subject project on August 30, 2007. On April 22, 2008, the Section
404 Permit was issued by the USACE (Action ID No. SAW-2007-0293-292). The
Section 401 Individual Certification was issued by the North Carolina Division of
Water Quality (DWQ) on March 17, 2008 (NCDWQ Project No. 2007-71470). Please
find attached the vicinity map and updated drawings. The attached permit drawings
are based on the final design approach for the project. A copy of the Final Record
Drawings will be provided to the agencies at the completion of construction.
The purpose of this submittal is to request a modification to the Section 404 and 401
permits for Section C and to request a Jordan Lake Buffer Authorization (Section C,
NORTH CAROLINA TURNPIKE AUTHORITY

Permit Site 31). After the USACE and NCDWQ issued the Section 404/401 Individual
Permit for Western Wake Freeway, the NCTA procured the services of Raleigh-
Durham Roadbuilders' (RDR) to construct the proposed project. On behalf of NCTA
and through the design build pursuit, RDR refined the original design of Section C to
provide the best project value to NCTA.
Since the time of the original permit application, the Jordan Lake buffer rules have
come into effect, and these rules only affect new stream crossings, of which there is
only one. The new site which is affected by buffer rules is Site 31 in Section C.
For project design and constructability purposes, RDR has divided Section C into
two sections: C1 and C2. This change results in the plan view reference number for
the attached permit drawings for the permit modification being different from the
original permit drawings. RDR has maintained the same numbering system of the
permit impact site to ensure an 'easy' comparison between the original permitted
impacts with the impacts for the proposed permit modification. Sites that are 'new'
are noted in each table as applicable and justification for these impacts are included
in this letter.
The refined design does not compromise the NCTA's compliance with the existing
permit conditions. The design refinement for Section C has been evaluated for
compliance with avoidance and minimization criteria and is in compliance with all
previous issues, including the following:
• Protected species;
• Aquatic life passage;
• FEMA compliance; and,
• Cultural resource.
Section C is currently under construction. Raleigh-Durham Roadbuilders (RDR) has
limited its work in Waters of the United States to comply with the authorized
permits or the minimized impacts noted in this modification request. Based on our
anticipated schedule, construction for Sections A and B would commence in 2010.
The 4B meeting for Sections A and B was held in October 2009, and the 4C meeting
was held February 24, 2010.
Summary of Changes to jurisdictional Impacts
The original permit for Western Wake Freeway included the preliminary design for
Sections A and B and final design for Section C. As noted previously during the
project's design build pursuit, RDR made several refinements to the Section C
project design to provide the best project value to the NC Turnpike Authority. These
changes included:
• Refined interchange layout at NC 540/Green Level Road;
• Refined interchange at NC 540/US 64 such that NC 540 goes over US 64
instead of under as originally designed; and,
• Refinements to roadway layout to balance fill and cut areas.
2
These changes resulted in several wetland impacts now being counted as
permanent fill instead of excavation. These refinements affect Sites 3 through 8.
Table 1 summarizes the overall impact changes that have occurred within Section C
since issuance of the Section 404/401 permits for Western Wake Freeway.
Table 1. Overall Impact Changes to jurisdictional Areas in Section C
Original Wetland Impact 11.26 acres
Modified Total Wetland Impacts 11.39 acres
Change in Impact Totals for Wetlands 0.13 acres
Original Stream Impact 6,931 feet
Modified Total Stream Impacts 6,997 feet
Change in Impact Totals for Streams 66 feet
Note: Although there is a greater amount of stream impact, there is actually 42 feet less of
streams requiring mitigation as Site 31 does not require mitigation.
Table 2 summarizes changes at each permit impact site in Section C for permanent
impacts to wetlands, including fill, excavation and mechanized clearing.
Based on these impacts, and that the stream is 108 feet, the impact to the Jordan
Buffer is allowable and no mitigation will be required because these impacts are
below the threshold of 150 feet and 0.33 acres.
Compensatory Mitigation
The North Carolina Ecosystem Enhancement Program accepted responsibility to
implement compensatory mitigation on behalf of the NCTA for Western Wake
Freeway. All of the permit sites in Section C are located in the Hydrologic Unit Code
03030002, and all impacts to wetlands are considered to be riparian.
Based on the changes to impacts to Waters of the US, there is an increase in
requirements to NCTA's compensatory mitigation (0.07 acres) for wetlands. It is
anticipated that this mitigation need can be used from excess mitigation in Section
B.
Table 4 summaries stream mitigation compared for sites under the existing permit
and those sites under the requested modification.

REGULATORY APPROVALS
Application is hereby made for the modification of the Section 404 Individual Permit
from the USACE as well as the 401 Water Quality Certification for the project.
Additionally, with to the addition of Site 31 in Section which is subject to the Jordan
Lake buffer rules, the North Carolina Turnpike Authority requests that this site's
impact be authorized under a Jordan Lake buffer authorization.

Appendix 2 - Colonial Gas Line Construction April 2010
The temporary disturbance associated with removing the existing CPC pipelines is
approximately 53 linear feet of one unnamed perennial stream (Photograph No. 1),
a confined 189 linear feet of two unnamed intermittent streams (Photograph Nos. 2-
3) and approximately 0.01-acre of wetland (Photograph 4). The construction of the
new CPC pipelines will temporarily disturb 64 linear feet of the perennial stream
and 70 linear feet of one intermittent stream and 0.01-acre of one wetland
(Photograph Nos. 5-7, Figure 2).
To minimize sedimentation to the intermittent streams during the pipeline
installation and subsequent removal activities, if flowing during the proposed work,
temporary dams will be constructed at each end of the maintenance area and the
stream (low will be pumped around the maintenance area at each site. The dams
will be constructed of sandbags or other suitable material, and the pump capacity
will be able to sufficiently accommodate the stream flow. The pumps will be
installed above the upstream dam with the discharge line routed through the
maintenance area, discharging immediately downstream of the downstream dam
(Appendix A).
Within the perennial stream, CPC will use a steel pipe flume to convey the stream
flow through the reach of stream to be disturbed. The flume will be used to
maintain flow to the downstream side of the disturbed area, and the excavation will
be carried out under the flume (Appendix B). Both techniques allow the
maintenance to take place without contact to flowing water (i.e., "in the dry'), thus
reducing downstream sedimentation. At the location the new pipelines cross the
perennial stream, the soils must meet minimum compaction standards; therefore,
the temporary flume pipe will be left in place until the stream is re-routed as
indicated in the NCTA permit application dated April 22, 2008
With respect to the wetland that will be disturbed during the activity, equipment
will be operated either from adjacent uplands or from prefabricated timber mats
Western Wake Freeway (TIP No. R-2635C) Page 2 of 3
Appendix 2 -Colonial Gas Line Construction April 2010
and stabilization will be conducted immediately following completion of the activity.
All excavated soils will be temporarily stored on adjacent upland areas until
backfilling of the excavation area. Topsoil will be segregated and stored separately
(Appendix C). Measures will be taken to avoid any hydrology alteration and existing
contours will be restored.
During the pipeline and ROW removal / relocation and subsequent stabilization
CPC's Soil Erosion and Sedimentation Control Plan will be implemented to protect
the streams and wetland from sedimentation (Appendix D). CPC will utilize
temporary workspace on each side of the existing and proposed ROW's; However,
these areas are located outside of all jurisdictional water boundaries.
