Did you know natural gas pipelines are the safest energy transportation system in the United States? We are committed to making them even safer.

The American Petroleum Institute's
Safety Management System

In 2017 we integrated the industry leading standards set by the American Petroleum Institute (API1173) into our existing programs and standards to form a single, umbrella framework providing a disciplined and formal method to manage pipeline safety risks and compliance issues. Learn more about the structure and benefits in our Safety Management System brochure.

In accordance with federal regulations, some segments along transmission pipelines have been designated as High Consequence Areas (HCAs) and supplemental hazard assessment and prevention programs (called Integrity Management Programs) have been developed.

National Grid is guided by an Integrity Management Program (IMP), which has been developed in accordance with rules established by the U.S. Department of Transportation (DOT) and local state regulatory agencies, which govern the program. The IMP was developed through the cooperation of industry experts, from both within and outside of National Grid, and meets or exceeds all federal requirements. The primary goal is to continuously improve safety by identifying, assessing and managing risks to natural gas pipelines.
