LEVEL 3 COMMUNICATIONS FIBER-OPTIC CABLE PROJECT
RALEIGH, N.C. TO RICHMOND, VA
PROJECT DESCRIPTION
Project Purpose & Description:
Level 3 Communications is building the first international fiber-optic network optimized
for Internet technology. The company is currently installing a nationwide long-haul
network for the transmission of long distance communications and data traffic.
Currently, PBNS is designing a segment from Raleigh, N.C. to Richmond, VA. The project
will install the fiber-optic network underground within existing roadway rights-of-way.
This portion of the network will begin north of the U.S. Route 1/ N.C. 401 interchange in
Raleigh (Wake County) and continues north along U.S. Route 1 through Franklin, Vance
and Warren Counties. The route will continue north to, and eventually beyond,
Richmond, Virginia. The majority of the fiber-optic line will be located along the western
portion or north-bound lane of U.S. Route 1 between Raleigh, N.C. and Warrenton Road
in Henderson, N.C. (Vance County). However, due to existing utilities and physical
features of the route, the line does change to the eastern portion or south-bound lane
between Warrenton Road and the State line. Enclosed are project vicinity maps as well
as USGS Quad Maps of the route.
The project will cross several streams and waterways along the route. The details of the
crossings affected by the project are contained in the attached Table of Waterway
Crossings.
Proposed Construction Methods:
The fiber-optics network will consist of a set of 12 innerducts (conduits) made of inert material
such as PVC (polyvinyl chloride) or HDPE (high-density polyethylene). Each innerduct is
approximately 1.25 inches in diameter and will be placed a minimum of 42 inches below
ground surface. After innerduct burial, fiber-optic cable is pulled through and spliced at
handholes. A handhole (48 inches long by 30 inches wide by 30 inches deep) is a concrete
and fiberglass composite structure used to house splices and maintain the cables. The
handhole will sit approximately six to 24 inches below ground surface and will be placed
approximately every 3,600 feet along the network.
The project will use the directional boring construction method for all waterway, tidal or
nontidal crossings. This method allows an innerduct to be bored directly under a
streambed without disturbing the bed or the banks. The staging area for this type of
bore is relatively small compared to a pipeline directional bore. This operation does not
require the digging of pits on either side of the stream to facilitate the placement of
equipment, as is the case with a jack and bore operation. The only potential impact is
the possibility of a leakage (frac-out) of the cutting and lubricating fluid (a non-toxic
bentonite clay or similar material). The small size of the bore hole and the limited
amount of cutting and lubricating fluid used reduce the risk of in-stream leakage.
Regardless, fluid flow controls will be available to seal the leakage quickly, and spill
containment material will be on-site. Fluid flow controls are intumescent materials that
will be injected into the bore hole to seal the leakage quickly. Typical drawing 3 of 7
depicts installation of innerduct by the directional bore construction method.
Other types of construction for the project include trenching and plowing. Open trench
construction involves excavating a width of 12 inches and a cover depth at least 42
inches. Equipment may vary but will include a track hoe, a rubber tire backhoe or chain
trenchers. The innerduct is placed in the trench and, as the backhoe excavates ahead,
sidecast material is back filled into the trench. Restoration will be complete within 2 days
and includes placement of select fill material compacted utilizing existing material
provided the material is free from rock and debris. The surface will be regraded to
conform to surrounding contours and restored as appropriate. Typical drawing 1 of 7
details typical trenching construction.
Direct burial cable plow technology uses a tracked bulldozer fitted with a cable reel on
the front end and a cable plow on the back end. In most areas, only one equipment
pass through the area is necessary. The cable plow is a single, straight-shafted blade,
which opens a narrow trench about 12 inches wide and four feet deep. The innerduct is
continually placed in the trench, and as the plow moves ahead the trench closes behind
the plow. The plow leaves behind a small ridge of material approximately 12 inches
above the original ground surface and a small open slot about 6 inches wide and 1 foot
deep. The project will restore this disturbance within two days as part of the cleanup
process. Typical drawing 2 of 7 depicts a typical plow construction.
Potential Impacts:
The fiber-optic cable will be placed in disturbed areas within existing roadway rights-of-
way. All waterway and wetland crossings will be installed by the directional bore method
that allows construction without direct disturbance to the waterway or wetland. The
trenching and plowing methods will occur in open areas.
Wetland delineations were not performed for the design and application portion of the
project. Wetlands will be verified and flagged in the field prior to construction. Any
wetlands encountered during construction will be directionally bored as discussed in the
previous section.
Most of the stream beds and/or wetlands areas will not be impacted by this project due
to the placement of the innerduct in relationship to the roadway. The innerduct will be
placed parallel to the roadway approximately 0-25 feet from the edge of pavement
(EOP) depending on the amount and location of existing utilities. The drawings indicate
proposed placement of the underground cable in relationship to edge of pavement
(EOP). Throughout the application, EOP refers to the white line on the roadway, not the
actual edge of the pavement or shoulder. Because of the proximity to the edge of
pavement, most areas of concern will be avoided.
Some of the stream crossings involve a box culvert and/or piping which cross the
roadway at depths (>6 feet) below the proposed innerduct running line. Other crossings
involve a structure which is closer to the roadway (within 6 vertical feet) and the
innerduct running line crosses the structure but does not affect the stream bed or
adjacent wetlands. In this case, the innerduct will be bored under the existing structure
to satisfy the minimum depth requirements. The fiber-optic running line will not impact
any of the crossings that are pipe and/or box culverts.
The project will not involve any withdrawal or discharge of water. The cable will be
placed in disturbed areas along existing roadway rights-of-way and will not impact or
restrict streamflows. All waterway and wetland crossings will be installed by the
directional bore method that allows construction without direct disturbance to the
waterway or wetland. The short duration of the boring will minimize any indirect effects
to these areas. The project will adhere to approved erosion and sediment control plans
during construction to minimize soil erosion into adjacent waterways.
General Mitigation Measures:
a. The necessary grading and brush clearing of stream banks will take place
immediately prior to cable installation to minimize the exposure of bare soil.
b. Stream bank and floodplain stabilization measures will be immediately implemented
upon completion of construction.
c. Wherever possible stream crossings will be avoided at a stream bend, in areas of
undercut banks, or in areas where the bank is unstable.
d. Uprooting of woody vegetation will be avoided to the greatest extent possible on
stream banks by minor rerouting of the cable route location, or by clearing
vegetation using equipment which leaves the root system intact (e.g., chain saw
or brushlog).
e. All grading will be performed in such a way as to minimize the introduction of
sediments into streams.
f. No artificial flow obstructions will be left in the streambed or channel.
g. The streambed and banks will be restored to stable contours to allow the
establishment of vegetation.
h. The mitigation measures will be monitored immediately after construction and
then weekly until the area is stabilized to check effectiveness and correct any
deficiencies.
All handholes will be located outside of streambeds and banks.
j. All staging areas for stream crossings will be located at least 100 feet away from
the stream. No refueling, equipment repair, or lubricating will be allowed within
100 feet of a stream. The only exception would be if a stream was found
adjacent to a road crossing with limited access and therefore requires such
activity. Proper spill containment materials will be used to isolate those activities
in order to minimize the risk of potential spills. A Construction Pollution
Prevention Plan will be completed and filed with appropriate agencies prior to
any construction activities.
k. Construction of stream crossings will be performed in accordance with any
applicable timing restrictions based on the classification of the waterway and the
appropriate regulations.

RE: Neuse River Riparian Area Rule: Utility Line Construction
This addresses utility line construction in compliance with the Neuse River Riparian Area Rule (15A NCAC
2B.0233) that became effective on July 22, 1997. This letter accompanies the Pre-Construction
Notification application required by the U.S. Army Corps of Engineers and the North Carolina Department
of Environment and Natural Resources for a Section 404 Nationwide 12 Wetlands Permit and Section 401
Water Quality Certification.
The Rule
The rule does not allow the removal of existing vegetation in the first 30 feet of land (known as Zone 1)
directly adjacent to a stream or other waterbody in the Neuse River Riparian Area, except in certain
situations. The rule allows utility crossings if conditions specified in Section 2(e) of the Rule are met and
also allows utility corridor construction and stormwater management facilities in Zone 2 of the riparian area
as long as conditions specified in Section 2(e) are met and they are located at least 30 feet from the top of
bank or mean high water line. The utility crossings, utility corridor construction, and stormwater
management facilities are allowed where no practical alternative exists. Section 2(e) states that "a lack of
practical alternatives may be shown by demonstrating that, considering the potential for a reduction in
size, configuration or density of the proposed activity and all alternative designs, the basic project purpose
cannot be practically accomplished in a manner which would avoid or result in less adverse impact to
surface waters. Also, these structures shall be located, designed and constructed to have minimal
disturbance, to provide maximum nutrient removal and erosion protection, to have the least adverse
effects on aquatic life and habitat, and to protect water quality to the maximum extent practical through the
use of best management practices".
The Project
Parsons Brinckerhoff is providing engineering and permitting services for a proposed fiber-optic
installation between Raleigh, North Carolina and Richmond, Virginia. The current route through North
Carolina begins north of the U.S. Route 1/ N.C. 401 interchange in Raleigh (Wake County) and continues
north along U.S. Route 1 through Franklin, Vance and Warren Counties. The fiber-optic cable will be
installed underground in existing rights-of-way on the west side of U.S. Route 1 in Wake County. The
Neuse River Riparian Area occurs on both sides of U.S. Route 1 in Wake County. All waterway and
wetland crossings will be directionally bored to avoid impacts. The project will include temporary
vegetation and soil disturbance for an approximate width of 20 feet for the length of the project. The
impacts will be self-mitigating as final stabilization and natural re-vegetation occurs. The project will not
involve any withdrawal or discharge of water. Please refer to the detailed project description that is
enclosed with the Pre-Construction Notification application.
Determination of "No Practical Alternatives"
Level 3 Communications is a communications and information services company that is building the first
international fiber-optic network optimized for Internet technology. The company is currently building a
national long-haul network for the transmission of long distance and data traffic from Charlotte to Raleigh,
N.C. The company seeks to extend the long-haul network from Raleigh, N.C. to Virginia, and beyond.
The majority of Wake County is located within the Neuse River Basin and, as a result, the basic project
purpose cannot be practically accomplished that would avoid or result in less impact to surface waters. A
change in the proposed running line location to avoid the Neuse River Basin would result in a major
change in the project's configuration and scope as the new route would bypass Wake County completely.
The placement of the utility line on the west side of U.S. Route 1 in Wake County reflects minimal
disturbance of existing utilities, roadways, and adjacent environmental conditions. Further, the project will
be located, designed and constructed to have minimal disturbance to waterways in the Neuse River
Riparian Area as indicated in the following section.
Page 2
Minimal Disturbance to Water Resources
The Level 3 Communications project will be located, designed and constructed to have minimal
disturbance to waterways and provide maximum water quality protection and erosion protection. The
utility line will be placed in disturbed areas within existing roadway rights-of-way. Most of the stream beds
and/or wetlands areas will not be impacted by this project due to the placement of the innerduct (conduit)
in relationship to the roadway. The innerduct will be placed parallel to the roadway approximately 0-25
feet from the edge of pavement (EOP) depending on the amount and location of existing utilities. The
EOP refers to the white line on the roadway, not the actual edge of the pavement or shoulder. Because of
the proximity to the edge of pavement, most areas of concern will be avoided.
All waterway (stream bed) and wetland crossings will be installed by the directional bore method that
allows construction without direct disturbance to the waterway or wetland. This method allows an
innerduct to be bored directly under a streambed without disturbing the bed or the banks. The staging
area for this type of bore is relatively small compared to a pipeline directional bore. This operation does
not require the digging of pits on either side of the stream to facilitate the placement of equipment, as is
the case with a jack-and-bore operation. The trenching and plowing method will occur in open areas.
Some of the stream crossings involve a box culvert and/or piping which cross the roadway at depths (>6
feet) below the proposed innerduct running line. Other crossings involve a structure which is closer to the
roadway (within 6 vertical feet) and the innerduct running line crosses the structure but does not affect the
stream bed or adjacent wetlands. In this case, the innerduct will be bored under the existing structure to
satisfy the minimum depth requirements. The cable running line will not impact any of the crossings that
are pipe and/or box culverts.
The project will protect water quality to the maximum extent practical through the use of standard Best
Management Practices. In addition, the following mitigation measures are proposed for stream crossings:
• The utility line will be located at least 30 feet from the edge of a stream or other waterbody.
• The necessary grading and brush clearing of stream banks will take place immediately prior to
cable installation to minimize the exposure of bare soil.
• Stream bank and floodplain stabilization measures will be immediately implemented upon
completion of construction.
• Wherever possible, stream crossings will be avoided at a stream bend, in areas of undercut
banks, or in areas where the bank is stable.
• Uprooting of woody vegetation will be avoided to the greatest extent possible on stream banks
by minor rerouting of the cable route location, or by clearing vegetation using equipment which
leaves the root system intact (e.g.: chain saw or brushlog).
• All grading will be performed in such a way as to minimize the introduction of sediments into
streams.
• No artificial flow obstruction will be left in the stream bed or channel.
• The streambed and banks will be restored to stable contours to allow the establishment of
vegetation.
• The mitigation measures will be monitored immediately after construction and then weekly
until the area is stabilized to check effectiveness and correct any deficiencies.
• All handholes will be located outside of stream beds and banks. A handhole (48 inches long
by 30 inches wide by 30 inches deep) is a concrete and fiberglass composite structure used
to house splices and maintains the cables. The handhole will sit approximately six to 24
Page 3
inches below ground surface and will be placed approximately every 3,600 feet along the
network.
All staging areas for stream crossings will be kept at least 100 feet away from the stream. No
refueling, equipment repair, or lubricating will be allowed within 100 feet of a stream. The only
exception would be if a stream was adjacent to a road crossing with limited access and
therefore requires such activity. Proper spill containment materials will be used to isolate
those activities in order to minimize the risk of potential spills. A Construction Pollution
Prevention Plan will be completed and filed with the appropriate agencies prior to any
construction activities.
• Construction of stream crossings will be performed in accordance with any applicable timing
restrictions based on the classification of the waterway and appropriate regulations.
• A Soil Erosion and Sediment Control Plan will be submitted to the North Carolina Department
of Environment and Natural Resources (Division of Land Resources) for approval before the
start of any construction.
Summary
This letter indicates that there are no practical alternatives for locating the fiber-optic cable project within
the Neuse River Riparian Area in Wake County. In compliance with the Neuse River Riparian Area Rules,
the Level 3 project will be located, designed, and constructed to have minimal disturbance to waterways,
aquatic habitat, and water quality due to its placement within existing, disturbed areas along U.S. Route 1.
All waterway and wetland crossings will be installed by the directional bore method that allows construction
without direct disturbance to the waterway or wetland. The short duration of the boring will minimize any
indirect effects to these areas. The project will not impact or restrict streamflows. The project will not
involve any withdrawal or discharge of water. The project will adhere to approved erosion and sediment
control plans during construction to minimize soil erosion into adjacent waterways. The project will also
protect water quality to the maximum extent practical through the use of mitigation measures and Best
Management Practices.

Level 3 Fiber-Optic Cable Project
City Pair: Raleigh, N.C. to Richmond, VA
Dear Mr. Tugwell:
Parsons Brinckerhoff Network Services, Inc. (PENS) provides planning, permitting, right-of-way
acquisition, project control, and design services for the installation of underground fiber-optic
cable for Level 3 Communications (the applicant). PBNS is representing Level 3
Communications in this request for verification that the discharge of dredged or fill material for
the construction of a proposed fiber-optic network will meet the requirements of the Section
404 Nationwide 12 Permit Program. Level 3 Communications proposes to directionally bore all
wetlands, streams, and other Waters of the United States.
The current route through North Carolina begins north of the U.S. Route 1/ N.C. 401
interchange in Raleigh (Wake County) and continues north along U.S. Route 1 through
Franklin, Vance and Warren Counties. The fiber-optic cable will be installed underground
within existing rights-of-way on the west side of U.S. Route 1 in Wake County. The direct
environmental impact of the proposed project will include temporary vegetation and soil
disturbance for an approximate width of 20 feet for the length of the project. The impacts will
be self-mitigating as final stabilization and natural re-vegetation occurs. All waterway and
wetland crossings will be directionally bored to avoid impacts. Minor impact to floodplains will
occur during construction, however, impacts will be minimal.
The Level 3 project will not threaten water quality standards and uses. The project will not
involve any withdrawal or discharge of water and will not impact or restrict streamflows. The
Over a Century of
Engineering Excellence

Level 3 Fiber-Optic Cable Project
City Pair: Raleigh, N.C. to Richmond, VA
Dear Ms. Manuele:
Parsons Brinckerhoff Network Services, Inc. (PBNS) provides planning, permitting, right-of-way
acquisition, project control, and design services for the installation of underground fiber-optic
cable for Level 3 Communications (the applicant). PBNS is representing Level 3
Communications in this request for verification that the discharge of dredged or fill material for
the construction of a proposed fiber-optic network will meet the requirements of the Section
404 Nationwide 12 Permit Program. Level 3 Communications proposes to directionally bore all
wetlands, streams, and other Waters of the United States.
The current route through North Carolina begins north of the U.S. Route 1/ N.C. 401
interchange in Raleigh (Wake County) and continues north along U.S. Route 1 through
Franklin, Vance and Warren Counties. The fiber-optic cable will be installed in existing rights-
of-way on the west side of U.S. Route 1 from Raleigh, N.C. to Warrenton Road in Henderson,
N.C. (Vance County) and on the east side of U.S. Route 1 from Warrenton Road to the State
line. The direct environmental impact of the proposed project will include temporary
vegetation and soil disturbance for an approximate width of 20 feet for the length of the
project. The impacts will be self-mitigating as final stabilization and natural re-vegetation
occurs. All waterway and wetland crossings will be directionally bored to avoid impacts.
Minor impact to floodplains will occur during construction, however, impacts will be minimal.
The Level 3 project will not threaten water quality standards and uses. The project will not
involve any withdrawal or discharge of water and will not impact or restrict streamflows. The
project will adhere to approved Soil Erosion and Sediment Control plans during construction to
minimize soil erosion into adjacent waterways.

LEVEL 3 COMMUNICATIONS FIBER-OPTIC CABLE PROJECT
RALEIGH, N.C. TO RICHMOND, VA
PROJECT DESCRIPTION
Project Purpose & Description:
Level 3 Communications is building the first international fiber-optic network optimized
for Internet technology. The company is currently installing a nationwide long-haul
network for the transmission of long distance communications and data traffic.
Currently, PBNS is designing a segment from Raleigh, N.C. to Richmond, VA. The project
will install the fiber-optic network underground within existing roadway rights-of-way.
This portion of the network will begin north of the U.S. Route 1/ N.C. 401 interchange in
Raleigh (Wake County) and continues north along U.S. Route 1 through Franklin, Vance
and Warren Counties. The route will continue north to, and eventually beyond,
Richmond, Virginia. The majority of the fiber-optic line will be located along the western
portion or north-bound lane of U.S. Route 1 between Raleigh, N.C. and Warrenton Road
in Henderson, N.C. (Vance County). However, due to existing utilities and physical
features of the route, the line does change to the eastern portion or south-bound lane
between Warrenton Road and the State line. Enclosed are project vicinity maps as well
as USGS Quad Maps of the route.
The project will cross several streams and waterways along the route. The details of the
crossings affected by the project are contained in the attached Table of Waterway
Crossings.
Proposed Construction Methods:
The fiber-optics network will consist of a set of 12 innerducts (conduits) made of inert material
such as PVC (polyvinyl chloride) or HDPE (high-density polyethylene). Each innerduct is
approximately 1.25 inches in diameter and will be placed a minimum of 42 inches below
ground surface. After innerduct burial, fiber-optic cable is pulled through and spliced at
handholes. A handhole (48 inches long by 30 inches wide by 30 inches deep) is a concrete
and fiberglass composite structure used to house splices and maintain the cables. The
handhole will sit approximately six to 24 inches below ground surface and will be placed
approximately every 3,600 feet along the network.
The project will use the directional boring construction method for all waterway, tidal or
nontidal crossings. This method allows an innerduct to be bored directly under a
streambed without disturbing the bed or the banks. The staging area for this type of
bore is relatively small compared to a pipeline directional bore. This operation does not
require the digging of pits on either side of the stream to facilitate the placement of
equipment, as is the case with a jack and bore operation. The only potential impact is
the possibility of a leakage (frac-out) of the cutting and lubricating fluid (a non-toxic
bentonite clay or similar material). The small size of the bore hole and the limited
amount of cutting and lubricating fluid used reduce the risk of in-stream leakage.
Regardless, fluid flow controls will be available to seal the leakage quickly, and spill
containment material will be on-site. Fluid flow controls are intumescent materials that
will be injected into the bore hole to seal the leakage quickly. Typical drawing 3 of 7
depicts installation of innerduct by the directional bore construction method.
Other types of construction for the project include trenching and plowing. Open trench
construction involves excavating a width of 12 inches and a cover depth at least 42
inches. Equipment may vary but will include a track hoe, a rubber tire backhoe or chain
trenchers. The innerduct is placed in the trench and, as the backhoe excavates ahead,
sidecast material is back filled into the trench. Restoration will be complete within 2 days
and includes placement of select fill material compacted utilizing existing material
provided the material is free from rock and debris. The surface will be regraded to
conform to surrounding contours and restored as appropriate. Typical drawing 1 of 7
details typical trenching construction.
Direct burial cable plow technology uses a tracked bulldozer fitted with a cable reel on
the front end and a cable plow on the back end. In most areas, only one equipment
pass through the area is necessary. The cable plow is a single, straight-shafted blade,
which opens a narrow trench about 12 inches wide and four feet deep. The innerduct is
continually placed in the trench, and as the plow moves ahead the trench closes behind
the plow. The plow leaves behind a small ridge of material approximately 12 inches
above the original ground surface and a small open slot about 6 inches wide and 1 foot
deep. The project will restore this disturbance within two days as part of the cleanup
process. Typical drawing 2 of 7 depicts a typical plow construction.
Potential Impacts:
The fiber-optic cable will be placed in disturbed areas within existing roadway rights-of-
way. All waterway and wetland crossings will be installed by the directional bore method
that allows construction without direct disturbance to the waterway or wetland. The
trenching and plowing methods will occur in open areas.
Wetland delineations were not performed for the design and application portion of the
project. Wetlands will be verified and flagged in the field prior to construction. Any
wetlands encountered during construction will be directionally bored as discussed in the
previous section.
Most of the stream beds and/or wetlands areas will not be impacted by this project due
to the placement of the innerduct in relationship to the roadway. The innerduct will be
placed parallel to the roadway approximately 0-25 feet from the edge of pavement
(EOP) depending on the amount and location of existing utilities. The drawings indicate
proposed placement of the underground cable in relationship to edge of pavement
(EOP). Throughout the application, EOP refers to the white line on the roadway, not the
actual edge of the pavement or shoulder. Because of the proximity to the edge of
pavement, most areas of concern will be avoided.
Some of the stream crossings involve a box culvert and/or piping which cross the
roadway at depths (>6 feet) below the proposed innerduct running line. Other crossings
involve a structure which is closer to the roadway (within 6 vertical feet) and the
innerduct running line crosses the structure but does not affect the stream bed or
adjacent wetlands. In this case, the innerduct will be bored under the existing structure
to satisfy the minimum depth requirements. The fiber-optic running line will not impact
any of the crossings that are pipe and/or box culverts.
The project will not involve any withdrawal or discharge of water. The cable will be
placed in disturbed areas along existing roadway rights-of-way and will not impact or
restrict streamflows. All waterway and wetland crossings will be installed by the
directional bore method that allows construction without direct disturbance to the
waterway or wetland. The short duration of the boring will minimize any indirect effects
to these areas. The project will adhere to approved erosion and sediment control plans
during construction to minimize soil erosion into adjacent waterways.
General Mitigation Measures:
a. The necessary grading and brush clearing of stream banks will take place
immediately prior to cable installation to minimize the exposure of bare soil.
b. Stream bank and floodplain stabilization measures will be immediately implemented
upon completion of construction.
c. Wherever possible stream crossings will be avoided at a stream bend, in areas of
undercut banks, or in areas where the bank is unstable.
d. Uprooting of woody vegetation will be avoided to the greatest extent possible on
stream banks by minor rerouting of the cable route location, or by clearing
vegetation using equipment which leaves the root system intact (e.g., chain saw
or brushlog).
e. All grading will be performed in such a way as to minimize the introduction of
sediments into streams.
f. No artificial flow obstructions will be left in the streambed or channel.
g. The streambed and banks will be restored to stable contours to allow the
establishment of vegetation.
h. The mitigation measures will be monitored immediately after construction and
then weekly until the area is stabilized to check effectiveness and correct any
deficiencies.
i. All handholes will be located outside of streambeds and banks.
j. All staging areas for stream crossings will be located at least 100 feet away from
the stream. No refueling, equipment repair, or lubricating will be allowed within
100 feet of a stream. The only exception would be if a stream was found
adjacent to a road crossing with limited access and therefore requires such
activity. Proper spill containment materials will be used to isolate those activities
in order to minimize the risk of potential spills. A Construction Pollution
Prevention Plan will be completed and filed with appropriate agencies prior to
any construction activities.
k. Construction of stream crossings will be performed in accordance with any

RE: Neuse River Riparian Area Rule: Utility Line Construction
This addresses utility line construction in compliance with the Neuse River Riparian Area Rule (15A NCAC
2B.0233) that became effective on July 22, 1997. This letter accompanies the Pre-Construction
Notification application required by the U.S. Army Corps of Engineers and the North Carolina Department
of Environment and Natural Resources for a Section 404 Nationwide 12 Wetlands Permit and Section 401
Water Quality Certification.
The Rule
The rule does not allow the removal of existing vegetation in the first 30 feet of land (known as Zone 1)
directly adjacent to a stream or other waterbody in the Neuse River Riparian Area, except in certain
situations. The rule allows utility crossings if conditions specified in Section 2(e) of the Rule are met and
also allows utility corridor construction and stormwater management facilities in Zone 2 of the riparian area
as long as conditions specified in Section 2(e) are met and they are located at least 30 feet from the top of
bank or mean high water line. The utility crossings, utility corridor construction, and stormwater
management facilities are allowed where no practical alternative exists. Section 2(e) states that "a lack of
practical alternatives may be shown by demonstrating that, considering the potential for a reduction in
size, configuration or density of the proposed activity and all alternative designs, the basic project purpose
cannot be practically accomplished in a manner which would avoid or result in less adverse impact to
surface waters. Also, these structures shall be located, designed and constructed to have minimal
disturbance, to provide maximum nutrient removal and erosion protection, to have the least adverse
effects on aquatic life and habitat, and to protect water quality to the maximum extent practical through the
use of best management practices".
The Project
Parsons Brinckerhoff is providing engineering and permitting services for a proposed fiber-optic
installation between Raleigh, North Carolina and Richmond, Virginia. The current route through North
Carolina begins north of the U.S. Route 1/ N.C. 401 interchange in Raleigh (Wake County) and continues
north along U.S. Route 1 through Franklin, Vance and Warren Counties. The fiber-optic cable will be
installed underground in existing rights-of-way on the west side of U.S. Route 1 in Wake County. The
Neuse River Riparian Area occurs on both sides of U.S. Route 1 in Wake County. All waterway and
wetland crossings will be directionally bored to avoid impacts. The project will include temporary
vegetation and soil disturbance for an approximate width of 20 feet for the length of the project. The
impacts will be self-mitigating as final stabilization and natural re-vegetation occurs. The project will not
involve any withdrawal or discharge of water. Please refer to the detailed project description that is
enclosed with the Pre-Construction Notification application.
Determination of "No Practical Alternatives"
Level 3 Communications is a communications and information services company that is building the first
international fiber-optic network optimized for Internet technology. The company is currently building a
national long-haul network for the transmission of long distance and data traffic from Charlotte to Raleigh,
N.C. The company seeks to extend the long-haul network from Raleigh, N.C. to Virginia, and beyond.
The majority of Wake County is located within the Neuse River Basin and, as a result, the basic project
purpose cannot be practically accomplished that would avoid or result in less impact to surface waters. A
change in the proposed running line location to avoid the Neuse River Basin would result in a major
change in the project's configuration and scope as the new route would bypass Wake County completely.
The placement of the utility line on the west side of U.S. Route 1 in Wake County reflects minimal
disturbance of existing utilities, roadways, and adjacent environmental conditions. Further, the project will
be located, designed and constructed to have minimal disturbance to waterways in the Neuse River
Riparian Area as indicated in the following section.
Page 2
Minimal Disturbance to Water Resources
The Level 3 Communications project will be located, designed and constructed to have minimal
disturbance to waterways and provide maximum water quality protection and erosion protection. The
utility line will be placed in disturbed areas within existing roadway rights-of-way. Most of the stream beds
and/or wetlands areas will not be impacted by this project due to the placement of the innerduct (conduit)
in relationship to the roadway. The innerduct will be placed parallel to the roadway approximately 0-25
feet from the edge of pavement (EOP) depending on the amount and location of existing utilities. The
EOP refers to the white line on the roadway, not the actual edge of the pavement or shoulder. Because of
the proximity to the edge of pavement, most areas of concern will be avoided.
All waterway (stream bed) and wetland crossings will be installed by the directional bore method that
allows construction without direct disturbance to the waterway or wetland. This method allows an
innerduct to be bored directly under a streambed without disturbing the bed or the banks. The staging
area for this type of bore is relatively small compared to a pipeline directional bore. This operation does
not require the digging of pits on either side of the stream to facilitate the placement of equipment, as is
the case with a jack-and-bore operation. The trenching and plowing method will occur in open areas.
Some of the stream crossings involve a box culvert and/or piping which cross the roadway at depths (>6
feet) below the proposed innerduct running line. Other crossings involve a structure which is closer to the
roadway (within 6 vertical feet) and the innerduct running line crosses the structure but does not affect the
stream bed or adjacent wetlands. In this case, the innerduct will be bored under the existing structure to
satisfy the minimum depth requirements. The cable running line will not impact any of the crossings that
are pipe and/or box culverts.
The project will protect water quality to the maximum extent practical through the use of standard Best
Management Practices. In addition, the following mitigation measures are proposed for stream crossings:
• The utility line will be located at least 30 feet from the edge of a stream or other waterbody.
• The necessary grading and brush clearing of stream banks will take place immediately prior to
cable installation to minimize the exposure of bare soil.
• Stream bank and floodplain stabilization measures will be immediately implemented upon
completion of construction.
• Wherever possible, stream crossings will be avoided at a stream bend, in areas of undercut
banks, or in areas where the bank is stable.
• Uprooting of woody vegetation will be avoided to the greatest extent possible on stream banks
by minor rerouting of the cable route location, or by clearing vegetation using equipment which
leaves the root system intact (e.g.: chain saw or brushlog).
• All grading will be performed in such a way as to minimize the introduction of sediments into
streams.
• No artificial flow obstruction will be left in the stream bed or channel.
• The streambed and banks will be restored to stable contours to allow the establishment of
vegetation.
• The mitigation measures will be monitored immediately after construction and then weekly
until the area is stabilized to check effectiveness and correct any deficiencies.
• All handholes will be located outside of stream beds and banks. A handhole (48 inches long
by 30 inches wide by 30 inches deep) is a concrete and fiberglass composite structure used
to house splices and maintains the cables. The handhole will sit approximately six to 24
Page 3
inches below ground surface and will be placed approximately every 3,600 feet along the
network.
All staging areas for stream crossings will be kept at least 100 feet away from the stream. No
refueling, equipment repair, or lubricating will be allowed within 100 feet of a stream. The only
exception would be if a stream was adjacent to a road crossing with limited access and
therefore requires such activity. Proper spill containment materials will be used to isolate
those activities in order to minimize the risk of potential spills. A Construction Pollution
Prevention Plan will be completed and filed with the appropriate agencies prior to any
construction activities.
• Construction of stream crossings will be performed in accordance with any applicable timing
restrictions based on the classification of the waterway and appropriate regulations.
• A Soil Erosion and Sediment Control Plan will be submitted to the North Carolina Department
of Environment and Natural Resources (Division of Land Resources) for approval before the
start of any construction.
Summary
This letter indicates that there are no practical alternatives for locating the fiber-optic cable project within
the Neuse River Riparian Area in Wake County. In compliance with the Neuse River Riparian Area Rules,
the Level 3 project will be located, designed, and constructed to have minimal disturbance to waterways,
aquatic habitat, and water quality due to its placement within existing, disturbed areas along U.S. Route 1.
All waterway and wetland crossings will be installed by the directional bore method that allows construction
without direct disturbance to the waterway or wetland. The short duration of the boring will minimize any
indirect effects to these areas. The project will,not impact or restrict streamflows. The project will not
involve any withdrawal or discharge of water. The project will adhere to approved erosion and sediment
control plans during construction to minimize soil erosion into adjacent waterways. The project will also
protect water quality to the maximum extent practical through the use of mitigation measures and Best
Management Practices.
