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.

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. This Standard Operating Procedure is property of ENSTAR Natural Gas Company and may not be copied or otherwise used by anyone other than ENSTAR employees without prior written permission from the Company STANDARD OPERATING PROCEDURES MANUAL No: 1715 ENSTAR Natural Gas Company (ENSTAR) Alaska Pipeline Company (APC) NORSTAR Pipeline Company (NORSTAR) Cook Inlet Natural Gas Storage Alaska (CINGSA) Title: Meter Location Standards and Drawings Revision No.: 011 Effective Date: 12/09/2014 Page No. 2 of 27 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.

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.

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 Pipe Burial Depth Requirements Distribution Mains Service lines Minimum Depth per DOT 192 24" Municipality of Anchorage ROW 42" ADOT 36" Matanuska Susitna Borough ROW 36" Wasilla ROW 48" Kenai Peninsula Borough ROW 48" ENSTAR Preferred Minimum Depth 48" 18" in ROW 42" 36" 36" 48" 48" 48" in ROW 12" on Private Property 42" 36" 36" 48" 48" 48" 42" 36" 36" 48" 48" 48" 42" 36" 36" 48" 48" 48" 42" 48" 48" 48" 48" 48" ROW City of 12" private property Transmission Lines Road Crossings B. C. D. E. 30" in Class 1 36" in Class 2 36" in road ditches and RR crossings 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 This Standard Operating Procedure is property of ENSTAR Natural Gas Company and may not be copied or otherwise used by anyone other than ENSTAR employees without prior written permission from the Company STANDARD OPERATING PROCEDURES MANUAL No: 2120 ENSTAR Natural Gas Company (ENSTAR) Alaska Pipeline Company (APC) NORSTAR Pipeline Company (NORSTAR) Cook Inlet Natural Gas Storage Alaska (CINGSA) Title: Pipe Installation Procedures Revision No.: 004 Effective Date: 03/26/14 Page No. 3 of 4 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. Plastic service lines, 1” IPS and under, may be plowed in with a vibratory plow attached to a trencher or other piece of equipment. The tubing material shall be planted in such a manner that the pipe is not in tension. A #12 tracer wire shall be wrapped around the tubing per SOP 2205 B, Static pull plows shall not be used to plow in mains or service lines. C. The pipe and tubing shall be visually inspected as it is installed. D. The service line shall be open trenched where depth requirements exceed those capable of achieving with the plow or where compaction is required. E. The plowed trench shall be “wheel compacted” using the trencher tires. VII Installation of Pipe in bores A. Installation of pipe in Uncased Bores 1. Generally uncased bores will be done with piercing tools (Hole Hawgs, Moles, etc) or by Horizontal Directional Drilling (HDD). 2. When using piercing tools, the gas pipe may be used to supply compressed air to the piercing tool. A piercing tool one size larger than the diameter of the pipe shall be used. 3. One or more tracer wires shall be pulled with the pipe. A high tensile stranded or stainless steel tracer wire shall be used on uncased bores. 4. The installation of locate marker balls at either end of the bore may be required. 5. All permit conditions shall be strictly adhered to when installing road bores. 6. When installing an uncased bore by HDD, a pull head one size larger than the carrier pipe shall be used to ream out the hole prior to pulling back. 7. In all uncased bores, the carrier pipe shall be inspected for signs of excessive tension which may occur during the pullback. Such bores shall be rejected and not used. B. Installation of Pipe in Casings 1. Casings may be installed in an open trench, auger bored or jacked into location.

VIII. ENSTAR Natural Gas Company (ENSTAR) Alaska Pipeline Company (APC) NORSTAR Pipeline Company (NORSTAR) Cook Inlet Natural Gas Storage Alaska (CINGSA) 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. .

Policy: These procedures shall be followed when installing and maintaining pipeline casings, spacers, seals and vents. Procedure: I. Pipeline Casings A. Pipeline casings under major roads or railroads shall be designed and all components specified by ENSTAR’s Engineering Department. The drawings shall specify the casing material, type and quantity of spacers, end seals and vents if applicable. B. C. D. II. The casings shall be designed to the specifications of the governing agency, i.e Alaska Railroad, Alaska Department of Transportation and Facilities, etc., to handle the intended loading on the casing. Casing materials may be steel, HDPE or other material specified by the engineer. In residential subdivisions, Schedule 40 ABS casings or an approved substitute material may be utilized for HDPE gas main or service line road crossings. The size and location of such casings shall be specified on the project drawings. The inside diameter of the casing pipe should not be more than twice that of the carrier pipe. Casing Spacers Insulating casing spacers will be used to isolate steel pipe from steel casing pipe. Plastic pipe may be installed in casings with or without spacers. Spacers shall be used on plastic pipe that is to be inserted into a steel casing where internal weld beads may damage the pipe. D. The spacers shall be bolted to the carrier pipe at intervals specified by the engineer. The manufacturer’s instructions shall be followed when installing casing spacers. E. When inserting the carrier pipe inside the casing, care shall be take to ensure the spacers do no slide along the carrier pipe and bunch up while being inserted. F. The electrical continuity of a steel carrier pipe shall be verified that the carrier pipe is not shorted to the casing. All shorts shall be cleared before the crossing will be accepted. A. B. C.

All casing ends on mains and transmission lines shall be sealed to prevent water and other contaminants from entering the casing. Service line casings shall generally be sealed to protect water from entering the casing. B. Generally on steel pipelines in steel casings, the ends will be sealed with a modular link belt seal or a boot type seal as specified by the engineer. C. The manufacturer’s installation instructions shall be followed when installing end seals. D. Casing end seals in an un-vented casing should designed such that the maximum allowable operating pressure of the carrier pipe shall not be carried by the casing, unless the casing pipe is designed to hold this pressure at a stress level of not more than 72% of SMYS. III. A. B. C. Casing Vents Generally casings will be unvented unless specified by the engineer. Vents may be polyethylene or steel depending on the specifications of the engineer. Vents must terminate in a vented post and be protected from the weather to prevent water from entering the casing. The vent should be placed a safe distance from the edge of the driven road or railroad tracks to prevent damage. The casing vent should extend above the surface high enough to protect debris from blocking the vent.

B. C. D. E. F. G. H. I. J. 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.

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.

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.

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 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.

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 This Standard Operating Procedure is property of ENSTAR Natural Gas Company and may not be copied or otherwise used by anyone other than ENSTAR employees without prior written permission from the Company STANDARD OPERATING PROCEDURES MANUAL ENSTAR Natural Gas Company (ENSTAR) Alaska Pipeline Company (APC) NORSTAR Pipeline Company (NORSTAR) Cook Inlet Natural Gas Storage Alaska (CINGSA) Title: Plastic Pipe Branch Saddle Hot Tap Procedure Revision No.: 003 Effective Date: 03/26/2014 Page No. 2 of 2 No: 2225 before continuing. 8.

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. .

Revision No.: 003 Effective Date: 03/27/2014 Page No. 1 of 4 Authorizing Signature: Dave Bredin Title: Operations Manager Scope: This procedure explains the materials and procedure used for installing wire connectors. Policy: To maintain the electrical continuity of locate wires used on all plastic pipe, locate wires will be connected by this procedure. When exothermic welding wires to steel pipes the welding 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. III. Drawing of Locate Wire Connection A. Attachment one (1) shows a sketch of the Thomas & Betts ratchet crimper, and typical connector applications. IV. Exothermic Welding for Wire Connections to Steel Pipe A. B. When it is necessary to attach a wire to a steel pipe the instructions in Attachment # 2 and the manufactures instructions shall be followed. When the connection has been completed the connection and exposed pipe shall be covered with an approved mastic pad, cap or tape to protect the exposed pipe and connection from corroding.

Policy: Effective February 2, 2010, ENSTAR shall install an Excess Flow valve on all new or replaced service lines serving a single-family residence Excess Flow valves shall be installed according to this procedure. Procedure: I. Definitions: A. An Excess Flow Valve (EFV) is a device that is installed in a natural gas service line, near the connection to the gas main that is designed to automatically shut off the flow of gas when the gas flow in the service line exceeds design limits. This excess gas flow can be caused by someone excavating and damaging the line or from damage to the line during a natural disaster such as an earthquake. B. Service Line serving single-family residence means a natural gas service line that begins at the fitting that connects the service line to the main and serves only one single-family residence. C. Replaced service line means a natural gas service line where the fitting that connects the service line to the main is replaced or the piping connected to this fitting is replaced. II. Installation Required A. An Excess Flow Valve (EFV) must be installed on any new or replaced service line serving a single-family residence. The EFV must comply with the performance standards in CFR49 Part 192.381. B. An Excess Flow Valve may be omitted if one or more of the following conditions exists. ENSTAR’s Engineering and Operations Supervisors shall identify the areas or situations in the gas system that meet these situations: 1. The service line does not operate at a pressure of 10 psig or greater throughout the year. 2. ENSTAR has prior experience with contaminants in the gas stream that could interfere with the EFV’s operation or cause a loss of service to the residence. 3. An EFV could interfere with necessary operation or maintenance activities. 4. An EFV meeting the performance standards in 192.381 is not commercially available to the operator.

EFV Manufacturer. 2. EFV Rating in (scfh) 3. Tie Down Information 4. Part # 5. Lot # IV. 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.

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.

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. III.

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.
