Project Description
North Carolina Natural Gas Corporation (NCNG) proposes to
' construct and operate approximately 3.53 miles (18,650 feet)
of 6" steel high pressure natural gas transmission pipeline in
Union County, North Carolina.
' Attachments No. 1 depict the project location beginning at
Line 16, 1,600 feet east of SR 1501, and ending 3,400 feet
' west of US HWY. 74.
All of the construction will be completed within the existing
NCNG 30 foot wide easement of Line 27. 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 550 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.

Erosion and Sediment Control Measures
Measures that will be utilized to control erosion and
sedimentation by NCNG and crews under contract to NCNG 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.
Project 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 fixed,
and will be modified and updated as necessary to cover general requirements'or
specific instances.
II , PTT-77T.= C_ONSTRIICTION
A. mene-al
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.
S. 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. Rot*te qt%1Pe--4r-cr and pan_nina
NCNG pipeline routes are selected to enable the safe and efficient
' transportation of natural gas from existing facilities, from 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.

4. Brush
Brush piles may be constructed of limbs, tops, etc. less
' than 4" in diameter along and outside of the right of way
.with the approval of the landowner. Brush piles should be
-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.

1. Initial Grading
The minimum amount of initial grading necessary to permit
safe pipeline construction will be used. Erosion control
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).
1 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.

t

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 the ditchline. It is used to
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. Ditching
1. Ditching Specifications
Generally, ditch width will be as described in Appendix
Table" 1. Pipeline depth 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 noise levels will be
limited to appropriate federal and/or state
requirements where applicable.
4.

I
3. Access Over Ditchline
Where necessary, temporary ditch crossings will be
constructed to allow livestock, vehicles, equipment, and
persons to safely cross the ditch. Typical crossing methods
I are illustrated in Figures 10, 11 - A & B, 14, and 1S of the
Appendix.
4. Topsoil Conservation
I 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.
I ilities
F
il
S. ac
e
:Drainage T
Crossing of drainage tiles will be avoided where possible.
if it is necessary to cross such facilities, they will be
I 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 tile facilities
may be relocated.
6. Ditchline Barriers
Ditchline barriers, as detailed in Appendix Figure 7, will
be installed in the ditchli.ne to slow-the velocity of runoff
I 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 traps will be used on steep slopes near
stream crossings to prevent excess erosion and
sedimentation. Figure 8 in the Appendix illustrates the
configuration of this type of trap.
I G. Bac . ";t1'nq
1. Backfilling Specification
To the greatest extent possible, backfilling shall be done
I 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.
I 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.

Ditchline barriers, detailed in Appendix Figure 7, maybe
installed to prevent backfill material from sliding or
' washing. Rip-rap may be used on steep embankments where
erosion is anticipated.
' and Restoration
rlpan
=
g.
Cleanup and restoration shall begin as soon as possible following
backfilling. During inclement weather conditions, temporary
' erosion control measures may be installed until final cleanup and
-
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
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.

_ 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 NCNG construction inspector.

1. General
t

L__J

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 river 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
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.

Equipment will not be parked in streams for cleaning
purposes.
Clearing
a. A maximum of 40 feet shall be cleared.
b. Tree stumps will be removed where necessary for
construction. All others will be cut off at ground
level and left in the ground. Refer to Section II.C.
for further details.
Grading
Grading will be kept to a minimum in the area of stream
crossings. When grading is necessary, it will be done from
the banks. Stream banks with slopes less than 20 percent
will not require grading.
.Spoil will be piled away from the stream and protected with
mulch, silt fences, and/or spoil pile sediment traps as in
Appendix Figure 8, so that it will not erode into the
stream.
On steep embankments, interceptor diversions illustrated in
Appendix Figure 3 shall be installed and drained off the
right of way into adjacent filter strips of natural
vegetation. Stone filters as in Appendix Figure S may be
used where insufficient natural vegetation exists. Where
necessary, water control devices will be installed within 48
hours of completing construction grading and maintained on
banks until restoration begins.
Ditching
a. Ditches across streams will be to minimum depths below
the stream bottom as speci.*"i ed in Table 2 of the
Appendix. Where possible, aitching will be done from
stream banks. Spoil piles will be placed far enough
from the stream to prevent sediment from entering the
channel. All precautions used during grading apply.
Local authorities will be contacted prior to disposing
of spoil from saline waters.
b. Directional Boring Large streams and rivers may be
crossed by the direction bore method from the bank
areas without disturbing the channel bed.
Backf illing
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.
8.

' 7. Restoration
The slope of the earth replaced adjacent to water crossings
will be the minimum of the original grade or
a. 1:1-34 or 67% for clay containing soils
b. 1:3 or 33%- for sandy or cohesive soils
If steeper final.slopes are necessary, they shall be
' stabilized using rip-rap, gabions, log barriers or other
site determined methods. Specifications will be provided
_
per job requirement.
Installation of gabions and log barriers must be approved
through NCNG Engineering by the North Carolina Department of
Environment, Health and Natural Resources.
' The right of 'way on stream banks will be seeded, fertilized
%and mulched according to specifications listed in Table 3 of
the Appendix. Local seed mixtures may be substituted in
some instances. Tack will be applied as necessary to
stabilize surface. where rip-rap or other stabilization
methods are required, seeding will not be necessary.
When stream banks are subject to moderate erosion, jute
netting as in Appendix Figure 16 may be used in place of
rip-rap.
Rip-rap used for bank stabilization should be of clean,
silt-free quarry run stone, The stone shall be large enough
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 50 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.

' B. Wetl and CrOaainas
1. General
' Precautions will be taken to minimize the effects of
installing a pipeline across environmentally sensitive,
wetland areas. Crossings of such.areas will be scheduled as
sub-projects to minimize the time required to install the-
' pipe.
Where practical, construction across wetland areas will be
' _ completed when water levels are low.
Construction equipment that minimizes permanent damage will
be employed. Mats, pads, wide track machinery, etc. may be
necessary to effectively install the pipe and minimize
' damage to the wetland. Appendix Figures 12 and 14 depict
typical use of mudboards and equipment mats or pads.
Construction equipment, materials, and fuels shall not be
' stored in wetland areas. Equipment shall not be refueled in
wetland areas.
A buffer zone of approximately lob feet to either side of a
' wetland shall be considered as also being environmentally
sensitive. Restrictions applying to wetlands should be kept
in mind and followed when practical in buffer zones.
2. Clearing
Refer to Section II.C.
' 3. Grading
Minimum grading will be performed in wetlands. Normally, it
' will not be required.
i
4. Ditch
ng
Standards set forth in Section II.F. apply to ditching of
' wetlands. However, the width of the ditch at the ton 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.

' When road crossings are made by the open cut methods, ditches
shall be back£illed 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 15:1 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. Bar4 ncrs
' 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. Erosion Control

L
Measures will be taken to ensure that the stability of railbanks,
railbeds, roadbanks and roadbeds are maintained during and after
pipe installation. Sandbags, sediment trams, 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 2.: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.

2. Written concurrence from D5M is required if the utility line is Installed
parallel-to and closer than 10 feet (3 meters) to a stream or if the utility
i line crosses a stream channel at less than 75 degrees or more than 105
degrees (I.e., not perpendicular stream crossing) of the strearn bank;
' 3. Construction corridors parallel to streams shall be placed at the turthest
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 locaffans shall be pfa*nted 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

' 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.
' Measures shall be taken. to prevent live or fresh concrete from coming
into contact with waters of the state until the concrete has hardened;
.4. 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 (1524 meters) apart.
' •10. An anti-seep. collar shall be placed at the downstream (utility line
gradient) wetland boundary and every 150 feet (45.7 meters) up the
gradient unfit the utility exits the wetland for buried utility fines. Anti-soep
collars may be constructed with class B concrete or compacted day.
Perpendicular wetland crossings less than 150 feet (45.7 meters) long do
not require anti-seep collars.
The compacted clay shall have a specific discharge of i X 104 cm/see or
' less. A section and plan view diagram is attached for compacted clay
and concrete anti-seep collars.
' The following specifications shall apply to class 6 concrete:
a) Mink num cement content, sacks
' per cubic yard with rounded
course aggregate 5A
b) MInlrn'Jm cement content, sacks
per cubic yard with angular
' course aggregate 5.5
c) Maxunum water-cement ratl4
gallons per sack 6.8
to stump range r to 4"
e) Minimum strength - 23 day psi 2,500
11. Placement of rip rap is restricted to stream bottom and banks directly

You have our approval, in accordance with the attached conditions, to place fill material in 0.58 acres of
wetlands or waters for the purpose of constructing a natural gas pipeline at SR 1501 to US 74, as you
described in your application dated 9 April 1997. After reviewing your application, we have decided that this
fill is covered by General Water Quality Certification Number 3101. This Certification allows you to use
Nationwide Permit Number 12 when it is issued by the Corps of Engineers.
This approval is only valid for the purpose and design that you described in your application. If you
change your project, you must notify us and you may be required to send us a new application. If total
wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required
as described in 15A NCAC 2H .0506 (h) (6) and (7). For this approval to be valid, you must follow the
conditions listed in the attached certification. In addition, you should get any other federal, state or local
permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control,
Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations. Also this approval will expire
when the accompanying 404 or CAMA permit expires unless otherwise specked in the General Certification.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing.
You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written
petition which conforms to Chapter 150B of the North Carolina General Statutes to the Office of
Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This certification and its conditions
are final and binding unless you ask for a hearing. -
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water
Act. If you have any questions, please telephone John Domey at 919-733-1786.
