Montana Liquid and Gas Pipeline Association

The Montana Liquid and Gas Pipeline Association (MLGPA) is comprised of pipeline operators in Montana that are dedicated to promoting pipeline safety by providing information for excavators, state residents, businesses, emergency responders and public officials.


Approximately 15,000 miles of pipelines crisscross Montana, safely transporting natural gas, crude and other energy products every day to homes, businesses and to other parts of the country.  Pipelines transport products that are part of our every day life and contribute to Montana’s community tax base.

The Gas Pipeline Safety Division of the Montana Public Utility Commission inspects, regulates and enforces intrastate gas pipeline safety requirements.  The Office of Pipeline Safety (OPS), within the U. S. Department of Transportation, Pipeline and Hazardous Materials Safety Administration (PHMSA) inspects, regulates and enforces interstate gas pipeline safety requirements and both interstate and intrastate liquid pipeline safety requirements.

Individuals who will be excavating near underground pipelines in Montana are required by law to contact their local One-Call center by dialing 811 at least two business days prior to beginning their project unless they meet exemption requirements outlined in Montana’s damage prevention law.
