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.

Meter Inspections by National Grid

National Grid is now required by the New York State Public Service Commission to perform periodic leak surveys and corrosion inspections on all meters – even those located indoors. These inspections are performed by Precision Pipeline Solutions, a licensed National Grid contractor, at no cost to our customers. We will reach out to you to schedule the inspection, or you can schedule a time that works best for you by calling Precision Pipeline Solutions at 1-844-749-8898.

Excess Flow Valve Notification

Did you know you can request installation of an Excess Flow Valve (EFV) on your existing gas service line under certain circumstances?  For more information, call National Grid at

Gas Operator Verification Required

As part of new safety regulations, National Grid is requiring that all Licensed Master Plumbers (LMPs) have their Operator Qualifications (OQs) verified by National Grid before issuing an order to reconnect gas after work has been completed on jurisdictional piping at a premise.  To get verified, please complete the verification form
