Commercial Gas Installation

1. Gas Load
The owner should submit in writing the connected gas load and the pressure required at the meter outlet (measured in inches of water column) to an NSTAR sales representative.

2. Gas Service Line
The owner should provide the sales representative with a scaled utility site plan identifying the footprint of the building and the location for all other utilities. The sales representative will identify the route for the gas service line. The owner should identify any underground barriers on their property (i.e. septic system, sprinkler system, underground electric lines, oil tanks, well, invisible fence etc.) and will be required to provide any necessary permits or recorded easements.

3. Meter Location
A sales representative will indicate agreed upon location on the Application for Gas Service, site plan, and the foundation of the building if it has been erected. If a change is required, the owner is responsible for notifying NSTAR prior to the installation.

4. Evaluation Process
Engineering approval may be necessary based on load requirements. The owner will provide a check for any necessary contribution or deposit for the gas service and will sign the NSTAR Application for Gas Service. If a change is required, the owner is responsible for notifying NSTAR prior to the installation.

5. Pre-Mark
NSTAR Gas will identify the boundaries of excavation with white spray paint.

6. Dig Safe - 888-DIG-SAFE (888-344-7233)
NSTAR Gas will notify Dig Safe to identify, locate and mark underground utilities.

7. Road Opening Permit
NSTAR Gas will apply for city/town/state permit(s) (if applicable).

8. Schedule Gas Service Line Installation
Prior to installing the gas service to:

• Existing Structure - a representative of the NSTAR Gas Distribution Department will contact the owner in advance with a tentative construction date.
• New Construction - the contractor must contact NSTAR Gas when all criteria have been met (all other utilities installed and within 6” of final grade).

9. Gas Service Line Installation
An NSTAR Gas or subcontractor crew will install service line from street to foundation. Open trench installations by your own excavator must be arranged through the NSTAR Gas distribution department. Your sales representative can provide you with the necessary contact person and requirements.

10. Gas Meter Installation
After the service has been installed and you have met all the requirements, call your sales representative to schedule the date for a gas meter. Here's a checklist of steps you should follow before calling us.

11. Restoration
The owner is responsible for the restoration of private property. NSTAR will restore the public property based on the town/city guidelines.
