New Construction  

Main Extensions

Before beginning your project, contact ENSTAR’s Marketing Department to determine if your property is served by a natural gas main, or if a main extension will be required to bring natural gas to your property. If a main extension is needed, we can provide you with a cost estimate and answer your questions regarding this process. Once the main extension has been designed, payment in full is required prior to main installation.

Service Lines

A new service line will be required to bring natural gas from the supplying main to your building. To begin your application, contact ENSTAR’s Marketing Department with the following information about your new building:

  • Legal description of the property (lot, block, and subdivision name)
  • Street address of the property
  • Type of building (if multi-unit, number of units and labeling order)
  • Total heated square footage of the building
  • On-site contact name and phone number
  • Current status of construction
  • A list of all natural gas-fired equipment to be installed, and exact connected load information for each unit

New Service Line Connection Packet

ENSTAR requires prepayment of service line and meter set fees. Once the application has been completed and signed, and the appropriate fees paid, the service line installation is scheduled by our Distribution Department. Service lines can be installed any time after the foundation is completed and backfilled to within 6" of finished grade and the meter location marked. To coordinate the installation or check on the scheduling status of a new service line, contact ENSTAR’s Distribution Department (or your local office if outside Anchorage). Please provide Distribution with the street address of your new building when you call as this will allow them to identify your project directly.

Excess Flow Valves

Effective February 12, 2010, ENSTAR is required by Federal Pipeline Safety Regulations 49 CFR 192.383 to install an Excess Flow Valve (EFV) in all new and renewed service lines that serve only one single-family residence.  An Excess Flow Valve (EFV) is a device placed inside the natural gas service line near the gas main that shuts off the flow of natural gas automatically if ENSTAR’s service line is broken or otherwise has excessive flow, thereby restricting the flow of gas and mitigating the potential for property damage. Such excessive flow can be caused by damage due to excavation, damage caused by a natural disaster such as an earthquake, or excessive flow due to additional gas-fired equipment being added to the service line that exceeds the design capacity of the EFV. EFV’s are designed for a specific flow range with some tolerance for additional load, and will be sized based on information provided by the Customer at the time application is made for a new or renewed service line. The cost of the initial installation of the EFV is included in the service line charge. Installation of an EFV will NOT protect against Customer appliance gas leaks, small service line punctures or gas meter leaks. An EFV may not protect against damages due to earthquakes or flooding.

 
CUSTOMER RESPONSIBILITIES

It is critical that the Customer inform ENSTAR’s Marketing Department before any additional gas-fired equipment is added to the service line. Failure to do so could cause the EFV to close, disrupting natural gas service to the home. If a larger EFV needs to be installed to handle the Customer’s increased load, the Customer will be responsible for the Company’s cost to replace the EFV. The Customer will be given an estimate of costs to replace the EFV, which can range from several hundred to several thousand dollars depending on factors such as time of year, location of the valve in relation to curb, sidewalks, and roadway, landscaping, depth, and Municipal and State right-of-way permit fees. The Customer will be charged the actual cost of the replaced EFV, not to exceed the estimate.

Should a Customer increase the load on the service line without notifying the Company causing the EFV to close, the Customer will be responsible for any and all costs and damages associated with the closed EFV, including but not limited to damage to the Customer’s dwelling and equipment, and the Company’s cost to repair and/or replace the EFV. The Company will not be responsible for any damage to a Customer’s dwelling or its contents in the event of a closure of an EFV. 

Meter Bar Installation

ENSTAR’s Distribution department will install a meter bar on your new building when installing the new service line. However, once the permanent service application has been completed, licensed plumbers may pick up a single meter bar at ENSTAR’s International Airport Road, Soldotna, or Mat-Su Valley offices and install it. This will allow the building’s internal, or “house”, piping to be tied in. The meter bar must be secured solidly to a stud wall and installed at the proper height in accordance with the requirements of ENSTAR. For meter bars with two or more meters, contact ENSTAR’s Customer Service Department to schedule the installation.

Residential Meter Requirements

An ENSTAR Marketing Representative will size the natural gas meter for your new structure based on the total square footage and total connected load of your new building, and will provide you with a diagram of the meter that will be installed to serve your needs. Based upon the size and type of the meter to be installed, a concrete meter pad may be required. Additionally, installation of 4" (four inch) pipe bollards filled with concrete may be required to protect ENSTAR’s meter from damages. Construction and installation of these items is the responsibility of the customer.

ENSTAR will attempt to accommodate the builder's or homeowner's preferred route for the service line and the meter location.  However, the criteria for service line placement and meter location are based on a number of factors including building codes and pipeline regulations, as well as industry standards and building design.  ENSTAR will make the final determination for the route of the service line and the gas meter location. 

When ENSTAR establishes new service to a structure, care is made to meet all of the current codes, regulations, and standards.  As codes and regulations change, ENSTAR will modify its practices to meet the new requirements.  ENSTAR generally does not retrofit older installations to meet new requirements.  When renewing, replacing, or repairing its facilities, ENSTAR may bring the facilities to current code and regulations.

  • When installing bollards, call for locates before digging.
  • Hand dig within 2’ (two feet) of ENSTAR’s service line and other utilities.

Natural gas meter requirements for all new gas service installations: (see meter drawing )

  • The building's foundation must be backfilled and all landscaping must be finished to within 6" of final grade before the service line can be installed.
  • A wall must be available to attach the meter assembly.  For approved remote meter locations, a pressure treated 8' x 6" x 6" post must be installed by the property owner.  Four feet of the post must be buried and four feet of the post must be exposed to mount the meter assembly.
  • Each structure on the property to be served must have an identifying service address and the preferred meter location must be clearly marked.  ENSTAR will determine the final meter location.
  • The meter assembly must not be located in living quarters, garages, carports, boiler rooms, under decks, or inaccessible locations.
  • The meter assembly must not be located in contact with the ground or in a depression below the general ground level.
  • The meter assembly must not be located in areas accessible by vehicles unless the property owner has adequately protected it with bollards, a concrete barrier, or equivalent.
  • The gas regulator vent on the meter assembly must not be closer than 36" in any direction from an ignition source including electric meters, electric receptacles, telephone, cable TV or security system junction boxes.
  • The meter assembly or service line piping must not be closer than 12" to any electrical ground rod, non-insulated ground wire, or underground wiring.
  • The gas regulator vent must not be closer than 36" horizontally or 72" vertically from an opening door, window, or other building opening such as vent terminations for dryers, ranges, or bathrooms.
  • The meter assembly must not be located in areas subject to damage from falling ice or snow, dripping water, or snow plowing.  All structures witha meter roof shall have the meters installed on the gabled end of the structure.
  • The gas regulator vent must be located at least 10' (6' in the Municipality of Anchorage) away from a mechanical air intake (the mechanical intake is installed by a contractor per the International Mechanical Code, which has been adopted by the State of Alaska and MOA; the MOA has reduced this distance from 10' to 6').
  • The meter assembly must not be located under or closer than specified by the appliance manufacturer's installation instructions to a gas appliance intake or vent termination.  This includes furnaces, boilers, fireplaces, water heaters, and all gas appliance vent terminations.  READ the appliance installation manual.
  • Homeowners and/or their mechanical contractors shall assume all responsibility when installing natural gas conversion burners.  Most oil-fired appliance manufacturers do not approve the use of natural gas conversion burners.  ENSTAR does not endorse the use of conversion burners.  Conversion burners are installed at the owner's risk.

Gas meters shall be located in ventilated spaces readily visible and accessible for examination, reading, replacement, and maintenance.

Meter Set and Unlock

Additional requirements before the natural gas meter can be installed and gas service turned on:

  1. The meter assembly must be installed with the center of the outlet tee 50" above final grade.
  2. The service line's flexible riser will be installed with an 'S' bend.  This bend must be maintained in the position it was originally installed.  If concrete is poured around the service line riser, a protective sleeve must be installed to allow flexible movement of the riser.
  3. Do not attach any electrical bond to ENSTAR's meter assembly or locate wire.
  4. House piping must be connected to the meter assembly outlet tee or on the outlet of commercial meters.  House piping must have an inspection "green tag" in Anchorage or Palmer city limits.  In other locations, an air test record from a licensed plumber/gas fitter, or air test witnessed by an ENSTAR Service Technician, is necessary.  Ai air test record tag must have the test date, service address and plumber/gas fitter license information documented on it.  Do not apply test pressure to gas appliance control valves.  Shut-off valves upstream of appliances should be closed or piping capped before the appliance.
  5. Do not connect any piping into the 1" plugged portion of the outlet tee on the meter assembly.  This is for ENSTAR's use only.
  6. The pressure test requirement for standard 1/4 PSIG (7" W.C.) meter installations is 10 PSIG.  The pressure test must be held for 10 minutes minimum duration with no leakage.  For elevated delivery pressures, the pressure test must be a minimum of 10 times the delivery pressure for a 30-minute minimum duration.
  7. At least one major appliance must be installed to code and manufacturer's instructions, connected to the house piping, and vented.  Unused openings in common vent tees must be plugged.  Unused openings of house piping must be capped.
  8. In remote areas, the service address must be posted at the road end of the driveway to aid ENSTAR personnel in finding the correct property.  The address must be posted on the building and the unit numbers must be posted on each unit when multiple units are served.  Permanent tags, indicating unit numbers, must be affixed to the gas piping at the meter location on multi-unit buildings.  Tags must match the unit number that was agreed upon when application for service was made.

Note: If these three items are not completed when a service person arrives to install and unlock a meter, a one-hour service charge at the prevailing hourly labor rate will be billed to your account.

To schedule installation of your permanent meter, please contact ENSTAR Customer Service with the street address and customer name as it appears on the service line application.
