There are over 2.5 million miles of pipelines in the U.S. today.  Greater Minnesota Gas operates both transmission pipelines and distribution pipelines, consisting of main lines (“mains”) and service lines.

Although pipelines are the safest means of transporting energy products, it is important to follow state Call Before You Dig guidelines.

Natural Gas is lighter than air and will generally rise and dissipate. It may gather in a confined space and travel to a source of ignition. Health Hazards of natural gas are as follows: Will be easily ignited by heat, sparks or flames and will form explosive mixtures with air. Vapors may cause dizziness or asphyxiation without warning and may be toxic if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, sever injury, and/or frostbite.

GMG Operates an estimated 700 square mile of distribution pipeline in 11 counties ranging in size from 2” to 6” in diameter.

What if a leak occurs:

To prepare for the event of a leak, we regularly communicate, plan, and train with local emergency responders. Upon notification of an incident or leak trained and qualified personnel are dispatched in response. Our technicians in partnership with emergency responders are trained to protect life, property and facilities by taking steps to minimize the amount of product that leaks out and to isolate the pipeline emergency.

We invest significant time and capital maintaining the quality and integrity of our pipeline systems. Field personnel continually monitor the pipeline system and are available for immediate response to any incident or leak.

Protect your property and your pocketbook.  Damages caused by customers who did not call before digging are paid for by that customer.  Calling first makes all the difference.

Call Before You Dig

Are you utilizing the Gopher State One Call 811 system? You must call in locates at least two business days prior to doing any digging on your property. By following this important step, you will prevent service interruption for both you and your neighbors.
