SECTION NG.01 - INTRODUCTION
DU standards of construction shall be utilized for all facilities to be owned, operated and
maintained by the utility, to include hookups from the utility facility to the demarcation point.
Generally, natural gas mains, service lines and meters will be constructed by DU or by DU’s
contractor at DU expense. Thus, these standards will be followed by DU contractors. In rare
circumstances, (with prior written approval of the utility), main/distribution facilities may be
constructed by the Army’s Facility Contractor for the utility, at DU expense. Thus, these
standards will be followed by the facility contractor.
In all cases natural gas meters and automated meter reading equipment will be installed, owned
and maintained by DU.
DU will be responsible for planning, designing and constructing utility water, wastewater, natural
gas, and electrical distribution system improvements for new government facilities. This will
require close cooperation and utility involvement in the government facility planning process.
Without this coordination, facilities constructed will have no utility service.
All connections or disconnections to the natural gas main, whether the natural gas main is
pre‐existing or new, will be performed by DU. Under no circumstances shall any person other
than a DU employee or authorized representative connect or disconnect any service line to a
natural gas main on Fort Richardson.
The government, Army, or Corps of Engineer will not be responsible for design, construction, or
oversight of any natural gas facilities owned by DU, whether natural gas mains, service lines,
pressure regulation equipment or meters.
The government facilities construction contractor will be responsible for connecting the
building’s internal fuel line piping to the shutoff valve on the customer side of the gas meter. DU
will provide and install the meter and downstream shut off valve. Coordination will be necessary
so that the appropriate meters are on hand for the facilities to be constructed.

Title: Measurement Supervisor
Scope: This procedure contains guidelines to where meters will be placed on buildings. It also contains
typical sizing information and Engineering drawings and specifications for typical meter sets.
Policy: This procedure shall be followed when establishing meter locations on buildings, sizing meters
and providing dimensions to customers for typical meter set assemblies.
Procedure:
I. ENSTAR Rate Definitions
Effective August 1, 2010, the rate a customer pays for gas service will depend on his total
connected gas equipment input requirement. The total connected load will be served by an
appropriately sized meter. The metering pressure, connected equipment load and meter size
will determine what rate the customer pays for gas service. It is critical the meter be sized
properly on all buildings for the customer to be billed properly. Four categories of gas service
are available. They are defined as follows:
A. G-1: this rate applies to natural gas service to any customer through a single meter for
any purpose, where the meter has a Company rated maximum capacity of 400 cubic
feet per hour (CFH) or less. (See Attachment 3). Note: the maximum capacity of a G-1
meter can be increased to 590 CFH for locations with a single, high efficiency, on
demand water heater with a maximum rated capacity of under 250,000 BTUH (250
CFH) and still be qualified for a G-1 rate.
B. G-2: This rate applies to natural gas service to any customer through a single meter for
any purpose where the meter has a Company rated maximum capacity of 401 cubic feet
per hour (CFH), but no more than 649 CFH. Note: the maximum capacity of a G-2
meter can be increased to 839 CFH for locations with a single, high efficiency, on
demand water heater with a maximum rated capacity of under 250,000 BTUH (250
CFH) and still be qualified for a G-2 rate.
C. G-3: This rate applies to natural gas service to any customer through a single meter for
any purpose where the meter has a Company rated maximum capacity of 650 cubic feet
per hour (CFH), but no more than 3000CFH. Note: the maximum capacity of a G-3
meter can be increased to 3190 CFH for locations with a single, high efficiency, on
demand water heater with a maximum rated capacity of under 250,000 BTUH (250
CFH) and still be qualified for a G-3 rate.
D. G-4: This rate applies to natural gas service to any customer through a single meter for
any purpose where the meter has a Company rated maximum capacity over 3001
(CFH).
E. For all residential locations with a standby generator, the metered load will be determined
by adding 50% of the “normal load” (i.e., the total load for the location not including the
standby generator load) to the standby generator load. This “emergency load”, or the
normal load, whichever is greater, will be used to determine the appropriately sized
meter. The customer will also be presented the option of setting a second, separate
meter for the standby generator. Distribution will use the total load to properly size the
EFV, as required.

F. For all locations that do not have an on-demand water heater or a standby generator, the
maximum rated meter capacity can be exceeded by 5% to account for diversification of
the gas usage for all gas fired appliances. The diversification factor applies only to
locations with multiple gas fired appliances.
II.
Meter Sizing
A. The Marketing Representative will indicate the customer's total connected load on the
service line application. For service lines with a connected load of 1000 CFH or greater,
a "Gas Equipment Usage and Pressure Data Sheet" (See Attachment 2) shall be filled
out by the Marketing Representative.
1. This data sheet shall be reviewed and approved by a Distribution Engineer
to ensure ENSTAR's distribution system is capable of meeting the load
requirements.
2. The Marketing Spervisor shall review and approve the "Request for Medium
Pressure" portion of the data sheet, when applicable. See SOP 2130, “2
PSIG and 5 PSIG Delivery Pressure Procedures”.
3. The approved data sheet shall be sent to the Measurement Supervisor for
gas meter and regulator sizing. The Measurement Supervisor shall return a
copy of the approved data sheet with meter sizing information to the
Marketing Representative.
B. The chart in Attachment 3, "Capacity of ENSTAR Gas Meters at the Indicated Metering
Pressure” 3 shall be used to determine the size of the meter that is to be installed. Meter
sizing for the G4 category will be determined by the Measurement Supervisor, who will
notify the Marketing Representative of meter type and size.
III.
Meter Location Requirements
A. The Marketing Representative shall provide each customer signing up for new gas
service a "Gas Meter Location" card, see Attachment 1, and instruct the customer to nail
or staple the card where they would like the meter located. The following conditions
shall be considered when choosing the meter location:
1. Meters must be located a minimum of 36 inches horizontally from a source
of ignition including electric meters and electric outlets.
2. Meters must not be located under an operable window.
3. Meters must not be in living quarters, garages, carports, covered patios,
boiler rooms, under decks, or in unventilated or inaccessible locations.
4. Meter and regulator must be located a minimum of 36 inches horizontally
from an intake air source. The meter and regulator may not be located
under an air intake. Venting of the regulator, may be required at the
discretion of ENSTAR’s Measurement Supervisor.
5. Meter should not be located where snow and ice from roofs could damage
the meter.
6. Customers shall be instructed to provide pipe bollards around commercial
meters per attached drawings.

Title: Pipe Installation Procedures
Revision No.: 004
Effective Date: 03/26/14 Page No. 1 of 4
Authorizing Signature:
Dave Bredin
Title: Director of Operations
Scope:
This procedure outlines the procedures for installing steel and plastic pipe.
Policy:
These procedures along with any special permit provisions shall be followed when
installing steel or plastic pipe.
Procedure:
I.
Installation of Mains and Service lines in an Open Trench
A.
Distribution mains and service lines may be installed in an open trench. Generally, a
small excavator is used to make the trench. Most trenches are a bucket width with near
vertical walls. Trenches can be wider when it is necessary to slope, shore or bench the
trench for protection from collapse.
B.
All necessary permits shall be obtained and reviewed prior to installing pipe in a trench.
Typically the Alaska Department of Transportation (ADOT) or City, Municipal or Borough
Public Works Department will issue ROW permits for gas mains and service lines.
C.
The trench bottom shall be free of large rocks that could damage the pipe.
D.
Plastic pipe shall not be installed in tension, rather it will be laid such as to allow for some
flexibility, i.e. snaked in the trench.
E.
The pipe will be covered with backfill material removed from the excavation. The pipe will
be backfilled with material removed from the trench in such a way to prevent large rocks
(fist size or larger) from impinging on the pipe.
F.
The locate wire shall be wrapped around plastic pipe per SOP 2205. It shall be inspected
for continuity after installation.
G.
The trench line shall not deviate from the staked line without prior approval from the
responsible surveyor, inspector or Supervisor.
H.
Steel gas mains or transmission lines shall be installed in such a manner to minimize
stresses to the pipe and protect the pipe from coating damage.
I.
When backfilling steel pipe the pipe must be firmly supported in the ditch bottom or
otherwise supported and the pipe and coating must be protected from equipment or
damage from the backfill.
II.
Inspection
A.
All pipe and fittings shall be visually inspected as it is installed in the ditch. Any scrapes
or gouges that would impair the serviceability of the pipe must be removed before being
backfilled. Generally, on plastic pipe, scrapes and gouges exceeding 10% of the wall
thickness shall be cut out and removed.
B.
The protective coating on steel pipe shall be inspected for holidays and repaired before
backfilling. All steel fittings shall be wrapped or protected with an approved coating
before backfilling.
C.
The pressure test may be done prior to backfilling or after backfilling. See SOP 2150 for
pressure testing parameters.

Burial Depth
A.
The burial depth will be the more stringent of the DOT 192 code requirement or the State,
Municipal or local ROW permit requirements. Generally pipe will be buried to the
”ENSTAR Preferred Minimum Depth” in most applications. See Chart Below

Generally gas mains must be installed with at least 24 inches of cover. Where an
underground structure prevents the installation of a transmission line or main with 24
inches of cover, it may be installed with less cover provided it is protected with additional;
protection to withstand anticipated external loads.
Gas mains may be installed with less than 24 inches of cover if the State or Municipal
permit allows for less cover or if it requires the main to be installed in a common trench
with other utility lines
All gas mains or transmission lines installed in a navigable river or stream must be
installed with a minimum of 48 inches cover in soil or 24 inches in consolidated rock.
Service Lines shall generally be installed with at least 12 inches of cover on private
property and at least 18 inches of cover in streets and roads. The ENSTAR preferred
burial depth of service lines in state and local ROWs is 48”. Where an underground
structure prevents installation at those depths, the service line must be able to withstand
any anticipated external loads

IV.
Underground Clearances
A.
Steel transmission mains shall be installed with at least 12” of clearance from any other
underground structure not associated with the pipeline. If this cannot be obtained the
pipe must be protected from damage that might result from the proximity of the other
structure.
B.
Each main must be installed with enough clearance form any other structure to allow for
proper maintenance and to protect against damage that might result from being close to
the other structure. Generally 12” separation from other utilities or structures is
acceptable.
C.
Each plastic main shall installed with sufficient clearance from any source of heat (i.e.
steam lines, hot water lines, etc) so at to prevent heat from impairing the serviceability of
the pipe.
V.
Compaction
A.
All permit conditions specifying compaction shall be adhered to when installing mains and
service lines across ROWs’.
B.
When not specified in a permit, road crossings and driveway crossings shall be
compacted to 95% in 12” lifts.
VI.
Plowing in Pipe
A.

Casing material shall be specified by the engineer.
Pipe shall be protected from damage, i.e. scrapes or gouges to plastic pipe or
coating damage to steel pipe, when inserted into a casing. The leading edge of
plastic carrier pipe shall be closed before insertion.
Steel pipe shall be separated from the casing pipe by the installation of casing
spacers. The carrier pipe shall be inspected to insure it is not in contact or
shorted to the casing pipe.
Casings under railroads and highways must be able to withstand the
superimposed loads. If there is a possibility that water could enter railroad or
highway casings, the ends must be sealed.
Vents may be required on some casings. If so they will be specified on the
drawings by the engineer.
Installation of Pipe Above Ground
A. Installation of plastic pipe above ground is generally temporary in nature such as for
temporary distribution feeds or temporary service lines.
B. Uncased plastic pipe in above ground applications may not be subjected to ultra violet
radiation from more than what the manufacturer recommends or two years, whichever is
greater. Generally ENSTAR uses plastic temporary service line tubing for one construction
season and then either buries the pipe as the permanent service line or discards the pipe.
C. Plastic pipe installed temporarily above ground must be protected from damage such as
vehicular traffic and other external forces.
D. Steel pipe installation above ground is usually limited to regulator stations, meter sets, block
valves, etc.

Flanges connect piping and components together in a system by the use of bolted
connections. This type of connection eases the disassembling and separation of piping
and equipment for repair and regular maintenance.
ENSTAR utilizes Raised Face Weld Neck Flange Type Connections through out its
system. This type of flange is connected to either steel pipe or weld fittings by buttwelding the protruding neck of the flange to the component.
Flanges are ASME/ANSI specification B16.5 for pressure classes of 150, 300, and 600.
Flange gaskets are used to provide a leak tight seal between two flange faces. The
gaskets used when connecting flanges must be designed for the pressure class for which
they are to be used.
ENSTAR utilizes Stud Bolts with two heavy hexagon nuts to connect flanges. The stud
bolts must meet the ASTM standard A193/A 193M Grades B7 and B16.
When tightening flange bolts, the flange faces must first align properly to provide even
contact on the gasket surface.
Before installing studs apply thread lubricant to each stud bolt.
The stud bolts should be installed hand tight and then evenly tightened in a crisscross
pattern to the correct torque specification. A moly disulfide lubricant shall be used to
lubricate studs before tightening.
All flange connections must be inspected for leaks before being placed into service.
See charts below for stud bolt tightening sequence and torque values.

1.
Prior to purging, plastic mains 3" in diameter and larger, shall be internally
cleaned by "pigging" with a foam "pig". "Pigging" mains less than 3" in diameter
may be required if installation conditions are extremely dirty or wet. The "pig"
shall be run as many times as is necessary to ensure no foreign material is
present in the pipeline.
2.
A wire brush "pig" shall be used to clean weld slag and scale in steel distribution
mains. A foam "pig" shall follow the wire brush "pig" and be run as many time
as is necessary to ensure no foreign material is present in the pipeline.
3.
Gas shall be injected into the main at a rate sufficient to prevent formation of a
hazardous gas and air mixture and to remove small particles not removed in the
cleaning process.
4.
When purging lines less than 3" in diameter (nominal) and less than 5,000' in
length, a steady flow of gas shall be purged through the purge point until a
strong smell of gas is readily perceptible. When a strong odor of gas is
perceptible, the purge point can be capped. All purge points must be soap
tested prior to being backfilled.
5.
When purging lines larger than 3" in diameter (nominal) and greater than 5,000'
in length, a steady flow of gas shall be purged through the purge point until a
100% gas concentration reading is detected using a combustible gas indicator.
When a 100% gas concentration reading is obtained, the purge point can be
capped. All purge points must be soap tested prior to being backfilled.
Repair of Damaged or Disconnected Facilities
A.
When repairing damaged mains or service lines it is necessary to test all pipe used in
the repair. This is accomplished by using pretested pipe that meets or exceeds the test
requirements of the pipe being replaced and soap testing all joints or mechanical
couplings. In lieu of using pretested pipe, testing of pipe and tubing may be done at the
site of the damage as part of the repair process.
B.
Each disconnected service line must be tested in the same manner as a new service
line before being put back in service. (The service line can be disconnected as the
result of a damage, relocation, move, abandonment, etc.). The service line must be
tested from the point of disconnection to the service line shut-off valve before
reconnecting. If provisions are made to maintain continuous service, such as by
installation of a bypass, any part of the original service line used to maintain continuous
service need not be tested.

Title: Operations Manager
Scope: This procedure outlines the equipment and steps necessary to squeeze off plastic pipelines owned and
operated by ENSTAR Natural Gas Company.
Policy: When squeezing off plastic pipelines in the ENSTAR distribution system, Company or contractor
personnel shall observe these procedures. Any deviation shall require approval, prior to the operation, by
the Distribution Mains Supervisor, who shall review the procedure with Engineering.
Procedure:
I.
Squeezing Plastic Pipe
Squeezing of plastic pipe shall be done using Company-supplied or approved devices only.
Squeeze-off tools used by the Company shall be of a design, which will ensure no damage to the
plastic pipe. The Squeeze–off tool shall be positioned a minimum distance of 3 times the pipe
diameter, or 12-inches, whichever is greater, from any fusion joint, mechanical connection, prior
squeeze-off point, or second squeeze-off tool.
A. Procedure for Squeezing operation using manually-operated tools are as follows:
1. Clean surface of pipe to prevent damage to plastic.
2. Inspect pipe for external damage such as cuts, scrapes and gouges before installing
squeezing tool. Do not squeeze on pipe sections with anomalies that are greater than 10%
of the pipe wall thickness.
3. Inspect squeezing tool to ensure surface is clean and tool is operating properly.
4. Insert grounding rod in wetted soil and inspect for proper connection to squeezing tool.
5. Install squeezing tool squarely on pipe and properly centered on pipe to ensure a good
shutdown and prevent damage to pipe
6. Tighten squeezing tool slightly and re-check tool alignment.
7. Complete squeezing operations. Compress the pipe at a slow rate to allow stress relaxation in
the pipe. The maximum compression rate is 2 inches per minute. Cold weather increases the
pipe’s susceptibility to damage. Compression and release times should increase in cold
weather.
8. Do not over squeeze the pipe. The squeeze-off tool should contain stops that limit the
squeeze to 70% of twice the maximum wall thickness of the pipe.
9. Lockout or Tag Out squeezing tool according to the Lockout/Tag Out Procedure found in this
manual.
10. After completing necessary work and lockout or tag out has been removed, open the
squeeze-off tool slightly, permitting gas to re-pressurize shutdown section of pipe slowly.
11. When removing the squeeze-off tool it is critical to release the squeeze very slowly. The
release rate should not exceed ½-inch per minute.
12. Loosen tool and rotate 90 degrees. Squeeze the pipe section to help pipe return to original
shape.
13. Remove tool from pipe, the pipe should be closely inspected for any signs of damage.
14. Wrap tape around the squeeze-off point for future identification. Do not squeeze in the same
place more than once.

B. The following procedure is specifically for the “Mustang Double-Bar Hydraulic Squeezing Tool
B Series”. All squeezing parameters shown in section A of this procedure in apply when using the
hydraulic squeezing tool.
1. Center the pipe under the upper jaw and insert the lower jaw under the pipe. Be sure the
proper stops are between the upper and lower jaw.
2. Open vent on hydraulic tanks.
3. Using the large piston, pump the upper jaw down, observing that the jaw remains
reasonably level after initial contact with the pipe. If the upper jaws slope more than ½inch, retract upper jaws, reposition tool and try again.
4. When a pressure of 500 to 750 PSIG is reached, switch to small piston and continue
pumping to 1,800 PSIG. Stop for at least two minutes and allow pipe to flow. Note that
gauge pressures should fall.
5. Pump 2,000 to 2,200 PSIG. Check for shutdown. Continue pumping until shutdown is
completed. (Complete shutdown occurs on 6-inch SDR 11 at about 2,300 PSIG)
6. Install saddle clamps and immediately tighten nuts evenly until a drop in hydraulic
pressure is observed on the gauge, 150 to 200 PSIG.
7. If pump is needed to run another squeeze tool, move four-way valve to neutral or “up”
position and remove hoses.
8. Lockout or Tag out squeezing tool according to the Lockout/Tag out Procedure found in
this manual.
9. After completing necessary work and lockout or tag out has been removed, reconnect
hoses with four-way valve in the “down” position. RE-establish pressure in the hoses.
Pump down until safety clamps can be removed easily.
10. Remove safety clamps.
11. Switch four-way valve to “up” position, retract upper jaw and remove squeezing tool.

Dave Bredin
Title: Director of Operations
Scope: This procedure outlines plastic pipe fusion welding procedures to be used when constructing or
repairing "plastic pipe" pipelines owned and operated by ENSTAR.
Policy: Plastic pipe used by ENSTAR shall be fused according to the pipe manufacturer's recommended
fusion procedures. Copies of the manufacturer's procedures are found attached to this procedure.
Procedure:
I.
Identification of Plastic Pipe
Since ENSTAR began installing plastic pipe in 1972, it has used only High Density Polyethylene
Pipe (HDPE) in its distribution system. The HDPE used by ENSTAR was produced by three
manufacturers; Phillips, Chevron, (Phillips and Chevron merged in 2000 to become Performance
Pipe) and PolyPipe. Before any fusion can be made, the manufacturer and type of pipe must be
identified. Each pipe used in ENSTAR system can be identified by distinct characteristics:
A. Phillips Driscopipe 7000, 8000 and 8100: ENSTAR sole-sourced Driscopipe 7000 and
8000 from 1972 to approximately 1999. The 7000 and 8000 pipe was shiny black in color
and is identified with a print line that clearly identifies the pipe as Phillips Driscopipe 7000 or
8000. Driscopipe 8100 pipe was used for several years in the 1998-2000 time frame and is
a black pipe with a thin co-xtruded yellow shell.
D. Chevron, Phillips, Performance Pipe, and PolyPipe HDPE pipes: In approximately 2000,
ENSTAR started using HDPE pipe produced by Chevron, Phillips and Polypipe. Chevron
and Phillips merged companies in 2000 to become Performance Pipe. Today ENSTAR
uses HDPE pipe under the name brands of Performance Pipe and PolyPipe. The brand
names of the HDPE pipe ENSTAR has used included Chevron Plexstripe II, Chevron
Yellowstripe II, Driscoplex 6800, PolyPipe 4810, 3408 and Polypipe GDB40 and GDB50.
These pipes can be identified by their print line and are black in color. The may have one or
more multiple yellow stripes. Some pipe may be solid black with no stripes.
II.
Fusion of Similar Kinds of Pipe
A. ENSTAR uses two specific butt and sidewall fusion procedures, depending on the type of
pipe.
1. For fusing Phillips Driscopipe 7000, 8000, or 8100 pipe: See Attachment A,
Driscopipe's "Heat Fusion Qualification Guide - Driscopipe 8000 Gas Distribution
Piping Systems". The butt and sidewall fusion procedures for fusing these specific
brands of pipe shall be done according to Attachment A.
2. All other HDPE pipes used by ENSTAR: See Attachment B, the Plastic Pipe
Institutes Generic Butt Fusion Joining Procedures (TR-33/2006) and See
Attachment C for the Plastic Pipe Institutes Generic Saddle Fusion Procedures (TR41/2002). When fusing any other type of HDPE pipe ENSTAR utilizes, fuse them
according to Attachments B and C.

A. When it is necessary to cross fuse Driscopipe 8100 to Driscopipe 7000 or 8000 pipe, the
same procedures for fusing Driscopipe 8000 to itself shall be followed. Follow the
procedures outlined in Attachment A. Note: The heater surface temperature is 475-500o F
and the Interface Pressure is 150 psi.
B. When it is necessary to cross fuse Driscopipe 7000, 8000, or 8100 pipe to any of the other
HDPE pipes used by ENSTAR, the preferred method of fusion is using electrofusion
coupling(s) or mechanical couplings.
1. Electrofusion couplings are the preferred method to cross fuse 2”, 3”, 4”, 6” and 8”
IPS pipe. See IIIC for alternate cross fusion procedure for 2” through 8” pipe
2. For ½” CTS, ¾” CTS and 1” IPS tubing, mechanical couplings are the preferred
method to connect Driscopipe 7000, 8000 or 8100 to any of the other HDPE pipes
used by ENSTAR.
C. For 2” through 8” IPS plastic pipe only, the procedures in Attachment 3, PLEXCO bulletin
C-6 "Qualified Cross Fusion Procedures for Joining PLEXCO PE3408 to Phillips Driscopipe
8000 may be used as an alternate cross fusion method if electrofusion couplings are not
available. The "Without Heat Shield" procedure is to be followed

Authorizing Signature:
Dave Bredin
Title: Operations Manager
Scope: This procedure outlines the equipment and steps necessary to fuse branch saddles by "hot tapping"
plastic pipelines owned and operated by ENSTAR.
Policy: When "hot tapping" branch saddle fittings installed in the ENSTAR natural gas system, Company or
contractor personnel shall observe these procedures. Any deviation shall require written approval, prior
to the operation, by the Distribution Mains Supervisor, who shall review the augmented procedure with
Engineering.
Procedure:
I.
Hot Tapping Plastic Pipe
In-line butt fusion fittings shall be the preferred method to install a branch connection. However,
to prevent unnecessary interruption of service, it shall be acceptable to utilize branch saddles
when approved by the Engineer or Supervisor prior to being installed.
A.
B.
Equipment used for hot tapping is presently supplied by McElroy Manufacturing, Inc. The
equipment requires minimal maintenance.
1.
Hot tapping tools shall be cleaned and lubricated after every use.
2.
Coupon from tapping operation shall be removed immediately after each use
and cutter returned to tapping position for next operation.
In order for the tool to function properly, it must be made up to an overall length as
stated below. The tool length is measured from the cap on the gland fitting to the point
on the concave side of the fitting that aligns with the outer line of the pipe main.
1.
Butt fuse a nipple 24 inches or longer to the branch saddle fitting.
2.
Fuse tapping tool to branch saddle nipple. Align hot tap tool so that needle
valve will point upward when fused to main.
3.
Fuse tapping tool and branch saddle nipple, but first check shell cutter to be
sure it has been reset to the proper tapping position.
4.
Measure the tool length to ensure proper make-up length. For 2-inch IPS (357/8 inch to 36-1/8 inch), for 4-inch IPS (52 +/- ¼”).
5.
Remove the 2-inch IPS insert from the lower fixed jaw.
6.
Install fusion unit on main for sidewall fusion, and position tapping tool in
movable clamp with branch saddle seated against main. Position moveable
jaws so there is at least 1/2-inch travel to permit sidewall fusion.
7.
Complete sidewall fusion using proper procedure. Allow sufficient cooling time

before continuing.
8.
Perform pressure test according to SOP 2150.
9.
Install 2 inch IPS insert in lower fixed jaw.
10.
Reverse fusion unit and install unit on tapping tool in tapping positron. Clamp
bearing housing in movable jaw and the gland fitting in fixed jaw.
11.
While applying pressure on fusion unit handle, ratchet the cutter drive shaft in a
clockwise direction to complete tapping operation.
12.
Pull cutter away from main as far as tool will permit.
13.
Place squeezing tool on branch 3 inches to 4 inches from branch saddle.
14.
Open the small valve on gland fitting to release trapped gas in tapping tool.
Cut the nipple at the fusion joint between the tapping tool and the squeezing
machine.
15.
Fuse new line to new side tap. The tie in joint does not have to be pressure
tested, but visibly checked and soap tested after pressuring the main with gas.
16.
Release squeezing tool and rotate 90 degrees. Pinch the sides to help bring
pipe back to shape.
17.
Remove coupon from shell cutter and reposition center for next operation.
Clean hot tapping tool and return to storage box.

instructions in attachment 2 and the manufactures instructions shall be followed.
Procedure:
I.
Locate Wire Connector Material
A.
B.
C.
The locate wire connector used by ENSTAR is a Thomas & Betts copper, C-tap
connector, Thomas & Betts Catalog No. 54705. A red marking identifies the connector.
The C-tap connectors are installed by using a Thomas & Betts ratchet crimper.
A vinyl mastic sealant pad manufactured by 3M Corporation is used to seal the
connection from moisture. Specifically, the sealant is a Scotch Brand, No. 2200, 3 1/4"
x 4 1/2 vinyl mastic sealant pad.
II.
Locate Wire Installation Procedure
A.
Strip approximately 1 inch of the protective coating from both wires to be connected. Be
careful when making a "service line to main connection", not to nick or break the locate
wire on the main.
B.
Insert the locate wires into the channel of the C-tap connector.
C.
Using the Thomas & Betts ratchet crimper, crimp the C-tap connector until the tool
releases.
NOTE: On the Thomas and Betts ratchet crimper tool there are four different color
settings for different applications of crimping. Use only the "red" setting for the red
connector.
D.
Wrap the connection with a 3M Scotch 2200 3 1/4" x 4 1/2" vinyl mastic sealant pad.
Fold the pad over the connector, do not roll the pad. Leave space between the wires so
that the pad can be worked between them to ensure that a watertight seal is made.

Installation Procedure
A. ENSTAR stocks three sizes of the RW Lyle, EFV. This style of EFV is designed to be
butt fused downstream of the outlet of a sidewall fusion saddle tee. The manufacturer's
installation instructions shall be followed.
1. EFV II 450, ½” CTS Valve can only be installed in a ½“ CTS (5/8 O.D.) service
line with a maximum total connected load of 400 CFH, provided the service line
is less than 200 feet in length. This valve is only to be used on service line
rerplacements and not on new installations.
2. EFV I 475(B), 1” IPS Valve can be installed in a ½“ CTS (5/8 O.D.) service line
with a maximum total connected load of 600 CFH, provided the service line is
less than 200 feet in length. If the service line length is greater than 200' the
tubing size must be increased to 3/4" CTS (7/8 O.D.) and have a maximum
length of 1500 feet.
3. EFV I 855(C), 1” IPS Valve can be installed in a 3/4" CTS (7/8 O.D.) service
line with a maximum total connected load of 1000 CFH, provided the service
line is less than 800 feet in length. If the service line length is greater than 800'
the tubing size must be increased to 1" IPS.
4. When the total load is greater than 1000 CFH or the service line length exceeds
the conditions above, ENSTAR's Engineering Department will be contacted to
size the appropriate EFV.
B. EFVs only work in one direction. Make sure the EFV is installed correctly according to
the direction-of-flow arrow on the valve. When installing an EFV on an existing service
tee the EFV must be installed within the first 5 feet of the service line.
C. Air Test and Purge the Service line per SOP 2150. When the EFV is installed introduce
pressure slowly so as not to trip EFV.

D. Test the EFV by quickly opening the meter stop cock to trip the valve. If the Excess
Flow Valve does not trip or reset properly contact your Operations Supervisor to
investigate the cause of the failure and take remedial measures.
E. The EFV allows a small amount of gas to weep past when closed. This allows the valve
to reset automatically after the line has been repaired. Verify that the EFV has been
reset by opening the stop cock slowly. An EFV may take up to 10 minutes to reset.
F. Use caution when working on a service line where the EFV has closed and expect a
small gas leakage. Use plastic pipe pinch-off tools to eliminate all gas leakage at a
repair point downstream of an EFV.
G. Install the Excess Flow valve tag / steel washer on the riser.
H. CAUTION: When installing temporary service lines off an existing MSA, check the MSA
for an EFV tag and service line records to see if an EFV has been installed. If the
service line has an EFV – do not run a temporary service line without approval from
Engineering and Operations Supervisors.

Title: Discharge Static Electricity
Revision No.: 001
Effective Date: 08/15/2008 Page No. 1 of 4
Authorizing Signature:
Dave Bredin
Title: Operations Manager
Scope: This procedure describes the conditions governing the generation of static electricity on plastic mains and
service lines, and the precautions to be taken to minimize the possibility of the ignition of gas when
working on plastic pipelines.
Policy: Prior to working on or squeezing off plastic mains and service lines in a gaseous atmosphere, these
procedures shall be followed to discharge any static electricity build up that may occur in the pipe.
I. How Static Electricity Forms on Plastic Mains and Service Lines
A.
Static electricity is the accumulation of stationary charges of electricity on a non-conductive
material, such as plastic pipe and tubing. These static charges can accumulate in large enough
quantities to cause a spark that could ignite natural gas.
B.
These charges can develop whenever gas flowing through plastic pipe contains rust or dirt.
Static charges can develop whenever gas flows at excessively high velocities through plastic
pipe. Situations that could cause these high velocities are line breaks where gas is escaping to
the atmosphere or where the cross sectional area of the plastic pipe is significantly reduced, for
example, when the pipe is being squeezed off. Static charges may be caused to discharge by
contact with clothing, dry soil surrounding the pipe or in the normal handling of the pipe during a
leak repair. Low humidity increases the possibility of static electricity accumulation.
C.
Static electricity on the surface of the plastic pipe is always a potential hazard and precautions
shall be taken to minimize its accumulation and discharge. Static charges can accumulate in
scattered pockets at any point along the plastic pipe.
D.
No work shall be performed on plastic pipe when a flammable gas-air mixture condition may
exist until the static charges have been dissipated using the methods described in this standard,
or unless the pipe has been purged of all gas.
II. Materials Needed for Controlling Static Electricity on Plastic Pipe
A. All employees that may be expected to control static electricity on plastic pipe shall carry on their
vehicle the following materials:
1. A gallon bottle containing a dilute solution of soap and water. The solution shall consist of
approximately one cap full of liquid dishwashing detergent to one gallon of water. Automotive
windshield washing fluid should be used in winter months in lieu of water to prevent freezing of
the solution.
2. A metal rod to be used as a ground rod.
3. A 20' piece of 1/4" cotton rope.

A. When grounding an open ended pipe such as in a line break situation or when purging gas from the
end of a new plastic main:
1. Wet the ground and rope with the soapy water solution.
2. Wrap a piece of wet rope around the pipe two or more times if possible. If it is not possible to
wrap the rope around the pipe, lay it over the pipe.
3. Ground the wet cotton rope by wrapping one end around a metal ground rod driven firmly into
moist soil.
4. Make sure the wet rope is in contact with the wet pipe and the wet earth. See Diagram 1 below.
5. If attaching a squeeze off tool, ground the squeeze off tool by inserting the
grounding probe attached to the tool into wetted soil.
Grounded Squeeze-off Tool on 2” HDPE Grounded Pipe
B. When grounding a continuous piece of pipe that is to be cut:
1. Wet the ground on one side of the cut area with the soapy water solution.
2. The span of the cut shall be bridged by wet rope wrapped around the pipe on either side of the
area to be cut. See Diagram 2 below.
3. Ground the wet cotton rope by wrapping one end around a metal ground rod driven firmly into the
moist soil.
4. If attaching a squeeze off tool, ground the squeeze off tool by inserting the grounding probe
attached to the tool into wetted soil.

C.
When the ground is frozen, it may not be possible to drive the grounding rod in the soil. When
this condition exists, place the end of rope on the wet earth and pour the soapy solution over the
rope to obtain a ground.
D.
When doing a butt or saddle fusion on a piece of pipe where static electricity has been
discharged, the pipe must be cleaned and dried at the actual point of fusion so that a good
fusion joint can be made in accordance with procedures for plastic pipe joining. If fusion is
needed in the area where wetted rope has been used, it is imperative that the area be
thoroughly cleaned.

E.
When pinching off blowing gas from small diameter plastic tubing, the tubing should grounded
by this procedure and the pipe kinked over to stop the flow of gas. A Vice-grip type squeeze-off
tool can then be applied. With no flowing gas, it is not required that the vice grip squeeze-off
tool be grounded. Vice-grip type squeezers must be grounded using a grounding probe and
cable if they are used to pinch off plastic tubing with flowing gas.
F.
Workers who must work in uncontrolled gaseous atmospheres shall wear proper personal
protective equipment including flame resistant clothing, i.e. NOMEX coveralls.
A fire
extinguisher shall be at the job site, readily accessible, when working in uncontrolled gaseous
atmospheres.
