Project Description
North Carolina Natural Gas Corporation (NCNG) proposes to
' construct and operate approximately 3.96 miles (20,923 feet)
of 8-inch diameter, 3.49 miles (18,404 feet) of 6-inch
diameter, 0.32 miles (1,675 feet) of 4-inch diameter, and
' 1.065 miles (5,625 feet) of 2-inch diameter plastic natural
gas pipeline in Union County, North Carolina. From station
61+93 to end, the pipeline is under 60 lbs pressure
' (intermediate pressure). From start to 61+93, the pipe is
under 150 lbs of pressure (medium pressure).
Attachments No. 1 depict the project location beginning
' approximately 185 feet north of SR 1512 along the existing
Rocky River Road (SR 1007) right-of-way and ending at the
intersection of Doster Road (1149) and the proposed
Stonebridge Subdivision Road right-of-way.
All of the construction will be completed within the existing
' NCDOT 60 foot wide right-of-way of both roads which the
pipeline will follow. An approximate 2-foot wide ditch will be
excavated in the right-of-way.

The minimum pipeline depth shall be 36-inches to the top of
the buried pipeline. Pipe depth may vary at specific locations
' to facilitate construction and future operations.
Construction shall be by conventional ditching and trenching
methods unless otherwise specified in Section 3 of this plan.
' Design, construction, and operation of this and all other NCNG
pipelines will be in strict compliance with the Department of
Transportation Pipeline Safety Regulations, Parts 191 and 192.
Existing Site
The project area is physiographically characterized as the
Piedmont environment. Ground elevation varies from 600 feet to
650 feet throughout the project area.
'
In general, topsoil in the proposed project area is a
combination of loamy sand and sandy loam, with loam being
found in the low, wetland areas. Sandy loam is fine grained
' and poorly drained, while loamy sand tends to be moderately
well drained. To a great extent, the northeast portion of the
project contains a higher percentage of loam and is slower
' draining.

The topsoil has a low erodibility with approximate factors
between 0.15 to 0.43. Section 3 of this plan explores the soil
in more detail at each sensitive area.
The disturbed land area of pipeline is divided into three
categories. These categories and the approximate acreage of
each area are as follows:
Disturbed Undisturbed Disturbed Disturbed % of
Surface Use Footage Footage Width Acreage Acreage
Woodland 3,650.00 0.00 10.00 0.84 7.93
Wetland 4,160.00 0.00 10.00 0.96 9.05
Farmland 38,299.00 518.00 10.00 8.80 83.02
Total 46,109.00 518.00 10.60 100.00
Environmentally Sensitive Areas
Environmentally sensitive areas are made up of 0.95 acres of
land that are wetland, adjacent to wetland, and adjacent to
rivers, creeks, and in some instances drainage channels.
Sixteen (16) areas are designated as sensitive.
Areas subject to erosion, particularly where the erosion could
easily result in sediment bearing runoff entering a wetland,
creek or river, are designated as sensitive. They are as
follows:
Area Reference
No. Station

Erosion and Sediment Control Measures

' Measures that will be utilized to control erosion
sedimentation by NCNG and crews under contract to NCNG and
are
included in Section 2 of this plan. The prescribed methods to
be used at specific sensitive areas along the right-of-way are
contained in Section 3. However, actual field conditions at
the time of construction and restoration may dictate the use
of more appropriate remedial measures.
The following modifications to this plan are required by the
North Carolina Department of Environment, Health and Natural
Resources:
1. Perimeter sediment control devices must be
installed prior to grubbing and grading at each
' sensitive area.

' 2. All temporary measures shall be maintained until
the areas which they serve are stabilized and
returned to the property owner by agreement.
' 3. Check dams per Section 2, Figure 23 are to be
installed at all interceptor diversion outlets.
4. All stone treatments shall be constructed using
at least NCDOT Class I riprap as per Section 2,
Figure 24. If the stone is not well graded, a
' suitable filter shall be installed beneath the
riprap.
' 5. Ground cover installed following construction must
be sufficient to restrain erosion in areas that
are not cultivated or covered with rock or stone.
' All seeded areas should be mulched and tacked if
possible.

Protect Schedule
From planning and construction through activation, the project
will take approximately 2 (two) months. The scheduled deadline
for finishing construction is December, 1997.

North Carolina Natural Gas Corporation shares concern and responsibility for
the environment of the State of North Carolina in which it operates. This
management plan addresses the environmental concerns encountered during
construction, maintenance, and operation of company facilities. The plan is a
summary of methods, devices and procedures which may be required for a
particular situation. This management plan is neither all inclusive or fisted,
and will be modified and updated as necessary to cover general requirements or
specific instances.
II . - DTvr-TTNE CONSTRUCTION
A. 29=--Ml
Generally, NCNG maintains six objectives during planning,
construction and operation of a pipeline:
1. Choose the best route for the pipeline.
2. 'Clear the minimum right of way to allow for safe
construction and operation.
3. Complete construction as expediently as possible.
4. Protect surrounding environment and ecosystems from
permanent damage.
5. Maintain a positive, cooperative working relationship with
local, state, and federal government agencies and personnel
within whose jurisdiction NCNG operates.
6. Operate and maintain NCNG facilities in a safe manner,
meeting or exceeding applicable codes and regulations.
it is the intent of NCNG to plan a pipeline in such a way as to minimize the
adverse impact on the environment and community. This Section (2) covers the
general environmental management plan. Requirements specific to this project
will be defined in Section 3.
B. gnute Sei ec^naand Di anni=
N=G pipeline routes are selected to enable the safe and efficient
transportat=on of natural gas prom existing Facilities, prom a
source, or to a market; in a manner compatible with the
environment. Environmental concerns include the following:
1. Protection of streams and woodlands

The crossing of all streams, creeks, woodlands, etc. is
avoided if possible. If a crossing or installation must be
made in such areas, the following three criteria are
observed:
a. Design to facilitate construction and maintenance.
b. Minimize damage to existing ecosystems, including
their banks and approaches.
C. Choose sites which facilitate control of runoff.
2. Protection of special concern animal or plant species
The majority of our pipeline projects are "small" according
to industry standards. They do not disrupt a sufficient
amount of land to destroy a complete natural habitat. The
duration of any disruption resulting from pipeline
construction is kept to a minimum in order to decrease
environmental impact.

3, Protection of cultural and historic resources
' If a cultural resource survey is required, it will be

4. Protection of scenic areas
' NCNG will construct and maintain pipelines and all other
facilities in such a manner as to minimize the adverse
impact to scenery.
5. Compatibility of pipeline with existing land use

3. Tree Stumps
Tree stumps will be removed where necessary to install pipe.
' Otherwise they will be cut as close to ground level as
practical. Stump removal is the responsibility of the party
clearing the right of way. Depending upon approval of the
' landowners, stumps may be:
a. Buried off the right of way
b. Windrowed along right of way
c. Removed from site and disposed of properly
d. Burned on right of way after permits obtained
4. Brush
' Brush piles may be constructed of limbs, tops, etc. less

with the approval of the landowner. Brush piles should
constructed approximately twelve feet wide with breaks every
' 100 to 200 feet or less to permit wildlife travel.
Alternatives to piling are as follows:
' a. Brush may be chipped and spread over right of way or
removed.
b. Brush may be burned where permitted by law. All
' required burning permits must be obtained.
5. Fence crossings
Where pipeline construction requires removal of fences,
' adecuate temporary fencing shall be installed. Figure 2, in
the appendix, describes an approved temporary fence and
gate.

1. Initial Grading
' The minimum amount of initial grading necessary to permit
eline construction will be used. Erosion control
safe nin
_
devices will be installed where necessary at the time of
initial grading.
2. Erosion Control Devices Associated with Grading
The erosion control devices contained in the Appendix are
temporary measures and are intended to be removed after
construction is completed. They will be replaced with
permanent erosion control devices or measures (such as
planting (where necessary).
The most useful accepted erosion control device is the
Interceptor Diversion. It is described in Figures 3a and 3b
' of the Appendix.
3. Mulch
Critical areas, such as banks sloping toward streams in the
' right of way may be temporarily stabilized by applying mulch
at the minimum rate of two tons per acre.

E. Road Construction
Roads associated with pipeline construction consist of two types:
temporary or construction path roads and semi-permanent or access
' roads.
1. Construction Path
This temporary roadway consists of a portion of the cleared

right of way adjacent to t
_ transport equipment and materials along the ditchline during
construction.
a. In wet and unstable soil conditions, corduroy and/or
brush mats may be used along the construction path. A
very neat corduroy configuration is presented in
' Figure 12 of the Appendix. However, since these are
temporary, they may be constructed of material
available along the construction site or hauled in
separately. Such improvements necessary for the
' construction path will normally be removed during
final grading and site restoration.
b. where the project inspector or contractor deems
' necessary, equipment pads as illustrated in Appendix
Figure 14 may be used.
' 2. Access Roads
Semi-permanent access roads will be constructed to all
permanent structures. They will consist of an adequate
amount of compacted base grade stone such as crush and run.
' They will be maintained by adding subsequent layers of
graded stone at periodic intervals.
' F. ?i tc'_^ing
1. Ditching Specifications
Generally, ditch width will be as described in Appendix
Table I. Pipeline death will generally be 36 inches below
the final graded surface or deeper. However, pipe depth may
vary according to Table 2 of the Appendix.
2. Blasting
All explosives shall be handled by qualified, experienced
personnel (licensed where required) in accordance with the
' U.S. Bureau of Alcohol, Tobacco, and Firearms, 27 CFR Part
181. Blasting will be done in a safe manner.
a. Blasting will not be done in established stream
channels without prior consultation with conservation
authorities. Damage to fish and other aquatic life
will be minimized.
b. Noise will be minimized and raise levels will be
limited to appropriate federal and/or state
requirements where applicable.

3. Access over Ditchline
Where necessary, temporar7 ditch crossings will be
constructed to allow livestock, vehicles, equipment, and
persons to safely cross the ditch. Typical crossing methods
are illustrated in Figures 10, 11 - A & B, 14, and 15 of the
Appendix.
4. Topsoil Conservation
Topsoil in farm and pasture lands will be removed from the
ditch and isolated from rock, debris, and subsoils according
to agreement with land owner. Every practical effort will
be made to replace topsoil in the top of the ditch during
backfilling. Appendix Figure 22 depicts an acceptable
method of handling topsoil commonly known as double
ditching.
5. :Drainage Tile Facilities
Crossing of drainage tiles will be avoided where possible.
If it is necessary to cross such facilities, they will be
protected or replaced and the original flow or feed
restored. Acceptable tile replacement methods are
illustrated in Appendix Figure 6.
When advantageous to both the property owner and North
Carolina Natural Gas Corporation, drainage the facilities
may be relocated.
6. Ditchline Barriers
Ditchline barriers, as detailed in Appendix Figure 7, will
be installed in the ditchline to slow the velocit_r of runoff
and prevent erosion. This method will be utilized when the
ditch will remain open for a considerable length of time in
a sloping area.
7. Spoil Pile Sediment Trans
Spoil pile sediment trans will be used on steep slopes rear
stream crossings to prevent excess erosion ana
sedimentation. Figure 8 in the Appendix illustrates the
configuration of this type of trap.
G. Ra k filling
1. Backfilling Specification
To the greatest extent possible, backfilling shall be done
immediately following placement of the pipeline in the
ditch. Soil from the ditch excavation will be used to
backfill where it is suitable and will not damage the
pipeline protective coating.
Backfilling shall be done in a manner that will ensure
proper settlement and not interfere with subsequent farming
operations. Every effort will be maintained to return
topsoil to the top grade of the filled area.
S.

Ditchline barriers, detailed in Appendix Figure 7, may be
' installed to prevent backfill material from sliding or
washing. Rip-rap may be used on steep embankments where
erosion is anticipated.
ti

on
-nLp and Restora
g, le
Cleanup and restoration shall begin as soon as possible following
backfilling. During inclement weather conditions, temporary
d
erosion control measures may be installed until final cleanup an
- restoration can be effectively accomplished.
1. Removal of Construction Debris
All construction materials, rubbish and debris remaining
from construction.shall be removed and disposed of properly.
2. ..Final Grading
The right of way will be restored to the original contour
with a smoothly finished final grade except in areas where
this would prevent access or maintenance on the pipeline.
Rock and other material resulting from construction which
' may interfere with farming shall be removed.
Permanent diversions shall be fertilized, limed, seeded and
mulched in accordance with Table 3 in the Appendix. They
shall be periodically inspected for effectiveness and
maintained accordingly.
3. Restoration and Stabilization
r As soon as practical following construction and after the
final grade is established, seeding and mulching shall
commence. Unless otherwise directed by local Soil
Conservation Services or soil analysis, the applicable rates
listed in Table 3 of the Appendix shall be used.
a. All rights'of way shall be regularly inspected and
maintained for the life of the facility.
b. Special seeding, restoring or stabilizing measures may
be required resulting from an agreement with the
' property owner.
Steep slopes may be stabilized with jute netting as

' 6. Restoring Manmade Structures
All manmade structures existing prior to construction which
are damaged or altered during construction will be repaired
' or replaced and left in equivalent or better condition than
they were in immediately prior to construction. Alternative
arrangements may be made with property owners.
I. Routine Noise Tmpact Mitfaatfon MAasures Du~in's Construction
_ All construction equipment shall be properly maintained so as not
to result in excess noise emission. Equipment will be utilized
during a normal Monday through Friday work week between dawn and
dusk. In order to reduce the overall time required to install a
pipeline, make up for bad weather, etc. work crews may also work
Saturdays.
Areas where specific noise limiting or scheduling will be required
shall.be outlined in the applicable contract or determined at the
discretion of the N NG construction inspector.
III gTREA n ANn WETTAND CROSSINGS
A. Stw am ro Sings
1. General
Each stream crossing will be treated as a separate
subproject for purposes of construction. This will enable
ditching, pipe installation, backfilling and stabilization
to be accomplished in sequence within a minimum number of
days.
Crossing of streams 20 feet wide or less and 3 feet deep or
less shall be accomplished within a 48 hour period. Typical
stream crossing methods are illustrated in Appendix Figures
10 through 15.
All stream and fiver crossings shall be constructed in
compliance with existing applicable regulations.
Equipment shall not be refueled within 100 feet of an
existing water source, spring, or well. Construction
materials, fuels, etc. will not be stored on the banks of
1 streams or areas subject to flooding.
2. Equipment Crossings
Minor streams where excessive rutting and sediment are not
anticipated will be crossed the least number of times
required for construction. Where stream banks and bottoms
will not allow for crossing without excessive damage and
sedimentation, temporary crossings shall be constructed.
Figures 12 and 14 in the Appendix illustrate the typical
installations of mudboards and equipment pads respectively.
' Where it is necessary to construct a stream crossing
utilizing a culvert, the crossing should be constructed as
illustrated in Figure 15 of the Appendix. This method
allows for a more dry ditch under the level of the stream
bottom.

areas without disturbing the channel bed.
6. Backfilling
Material used for backfill of a stream crossing shall be
coarse enough to remain in place when the stream is flowing
at normal velocities. Backfill material can be ditch
material or gravel hauled to the site. Silt will not be
used. Appendix Table 4 lists the size of stream bed
material that various stream velocities can transport.

to prevent displacement by the normal steam current.
' Rip-rap will extend from the stabilized stream bed or
channel bottom to the top of the stream bank or to the point
on the bank determined by the water level of the So year
storm, whichever is lower. The thickness of the rip-rap
' shall be at least 6 inches and slope no more than 1:1. In
general, the normal slope of the stream bank will be
maintained.
If consistent with land use and property owner agreement,
the right of way on stream banks may be planted with shrubs,
etc.
' 8. Hydrostatic Test Water
Test waters shall be discharged so as to minimize the
resultant impact on the environment. Where possible, the
water will be discharged into stabilized, heavily vegetated
areas where erosion and sedimentation will be minimized.
If such an area is not readily available, a stone filter as
' illustrated in Appendix Figure 5, shall be constructed to
accomplish the same task. Potable water is often used.

' 2. Clearing
Refer to Section II.C.
3. Grading
Minimum grading will be performed in wetlands. Normally, it
' will not be required.
4. Ditching
Standards set forth in Section 1_.F. apply to ditching of
wetlands. However, the width of the ditch at the top will
generally be wider and the slope of the ditch sides less
steep in order to prevent caving.
' S. Backfilling
immediately following pipeline construction, the ditch will
' be backfilled as per Section II.G.
6. Restoration
Wetland areas shall be restored to normal contour following
construction. Where land was grass covered or meadow land
prior to construction, the surface shall be restored using
methods of seeding and mulching as prescribed in
' Section II.H.

' IV. RAIL ROAD, FIGRWAY AND ROAD CROSSINGS
All crossings shall be made in accordance with the specifications and
requ irements contained in the applicable permits.

A. .y-+j.S way "gaffic Control
The normal flow of traffic will be disrupted as little as possible
during construction. Sufficient signs, barricades and lights
shall be erected and maintained during construction near roadways
_ to ensure the public safety.
Flagmen will be used on heavily travelled roads during
construction if they are necessary to maintain safe traffic
conditions.
All conditions issued by the highway department having
jurisdiction shall be followed. Example of acceptable equipment
crossings are illustrated in Figures 19 and 20 of the Appendix.
B. Open Road Cuts
All paved state roads and federal highways shall be crossed by the
boring method. Other roadways, normally unpaved, may be crossed
by the open cut method.
When road crossings are made by the open cut methods, ditches
shall be backfilled as follows:
1. Cover pipe with a minimum of six inches of sand pad.
2. Fill the remaining ditch to surface grade level with well
' tamped gravel or preferably with run-of-crusher (crush and
run) stone with approximately ISU stone-cement mixture or
equivalent.
3. After backfilling, the surface grade will be temporarily
restored until settling has occurred and permanent repairs
can be effectively made.
C. O -Pqs
Figure 17 of the Appendix illustrates a cross section of a typical
crossing completed by the boring method. Casing may be required
' and is illustrated in the figures.
Railroad crossings will be typically completed by boring according
to Figure 21 in the Appendix. Specific requirements of the
applicable permit will be met.
D. AroS;on Font _a
' Measures will be taken to ensure that the stability of railbanks,
railbeds, roadbanks and roadbeds are maintained during and after
pipe installation. Sandbags, sediment traps, etc. may be required
to prevent damage around boring pits. Water from boring will not
' be discharged into streams. Where possible, this sediment laden
water will be pumped to vegetated areas where material percolation
and filtration can occur.
All disturbed areas will be restored to normal or better
conditions, including the ditchline.

INTERCEPTOR DIVERSION
Interceptor diversions are the most common and effective device used for erosion
' control on pipeline construction. Typically, this device consists of an 18" to
24" high curb constructed across the ROW with a maximum of 2% outslope. The curb
is constructed of compacted earth fill with side slopes of 1:1 or flatter to
' allow the passage of construction equipment. The outlet of the diversion can
be stabilized with natural vegetation, rock, brush, or staked hay bales which
are buried four inches. Spacing of interceptor diversions will be in accordance
' with Figure 3. Temporary diversions will be maintained until permanent
diversions are installed. In some cases, diversions are not installed due to
' the desires of the landowner, i.e., plowed fields, etc.
If slopes with shallow bedrock, which will not permit grading to the extent
required for the above described device, are encountered, an open top culvert
can be substituted. These are channels constructed on half round pipe, hardwood
' lumber, etc. and will be installed in the same manner as interception diversions.

waters and wetland areas as described in 33 CFR 330 Appendix A (8) (12) and
General Permit No. 198100049 of the Corps of Engineers regulations (i.e., include any
fist activity for utility line backfill and bedding. This certification replaces Water Quality
Certification Number 2664 issued on January 21, 1992 and is rescinded when the
Corps of Engineers reauthorize Nationwide 12 or Regional Permit 049.
' The State of North Carolina certifies that the specified category of activity will
not violate Sections 301, 302.303; 306 and 307 of the Public laws 92-500 and 95-

' Conditions of Certification:
' 1. Activities covered by this general Certification do not require written
concurrence from the Division of Environmental Management (DEM) as
long as they comply with all conditions of this General Certification and
' the conditions of Nationwide 12 or Regional Permit 049;
2. Written concurrence from DIN is required if the utility tine is installed
' parallel-to and closer than 10 feet (3 meters) to a stream or If the utility
line crosses a stream channel at less than 75 degrees or more than 105
degrees (i.e., not perpendicular stream crossing) of the stream bank;
' 3. Construction corridors
parallel to streams shall be placed at the furthest
distance from the stream to the maximum extent practicable;
' 4. That established sediment and erosion control practices are utilized to
prevent violations of the appropriate turbidity water quality standard (50
NTUs In streams and rivers not designated as trout waters by DEM; 25
NTUs in all salt water classes, and all lakes and reservoirs; and 10 NTUs
in trout waters). All sediment and erosion control measures placed in
' wetlands shall be removed and the natural grade restored after the
Division of Land Resources has released the project;
' 5. Annual species suitable for wet locatlons shall be planted within
jurisdictional wetlands for soil and erosion control. Perennials such as
fescue are prohibited;
' 6. No fertilizer shall be applied within 10 feet (3
meters) of streams;

45
t 7. The construction corridor (including access roads and stockpiling of .
materials) is limited to 40 feet (12.2 meters) in width and must be
' minimized to the maximum extent practicable.
8. Measures shall be taken to prevent live or fresh concrete from coming
into contact with waters of the state until the concrete has hardened;
9. Permanent, maintained access corridors shall be restricted to the
' minimum width practicable and shall not exceed 10 feet (3 meters) in
width except at manhole locations. A 10 feet (3 meters) by 10 feet (3
meters) perpendicular vehicle turnaround must be spaced at least 500
feet (152.4 meters) apart.
•10. An anti-seep collar shall be placed at the downstream (utility One
' gradient) wetland boundary and every 150 feet (45.7 meters) up the
gradient unfit the utility exits the wetland for buried utility lines. Anti-seep
collars may be constructed with class B concrete or compacted clay.
Perpendicular wetland crossings less than 150 lest (45.7 meters) long do
not require anti-seep collars.
The compacted clay shall have a specific discharge ' of 1 X 10'3 cm/see or
less. A section and plan view diagram is attached for compacted clay
and concrete anti-seep collars.
t The following specifications shall apply to class B concrete:
' a) Minimum cement content, sacks
per cubic yard with rounded
course aggregate

impacted by the placement of the utility line. The stream berm must be
restored to the original contour after construction;
12 This general certification does not authorize any permanent changes in
preconstruction elevation contours in waters or wetlands. The permittee
' will have a specific plan for restoring wetland contours. Any excess
material will be removed to a high ground disposal area;
' 13. If an environmental document is required,,this Certification is not valid

46

until a FONSI or FOOD is issued by the State Clearinghouse;
14. Stormwater management shall not be required for this Certification;

felt project shall result in revocation of this Certification for the project.
' The Director of the North Carolina Division of Environmental Management may
require submission of a formal application for individual certiftcation for any project in
this category of activity, if it is determined that the project Is likely to have a significant
adverse effect upon water quality or degrade the waters so that existing uses of the
wetland or downstream waters are precluded.
' Public hearings may be held for specific applications or group of applications
prior to a certification decision if deemed In the public's best interest by the Director of
