Fact Sheet

Pipeline Safety

The natural gas industry operates an extensive system of 2.4 million miles of distribution and transmission pipelines that stretch across the country to provide service to more than 177 million Americans. The design, construction, operation, inspection and maintenance of all operating pipelines are subject to state and federal regulations and requirements. According to the U.S. Department of Transportation, pipelines are the safest, most environmentally-friendly and most efficient and reliable mode of transporting natural gas.

Fact Sheet

Gas Transmission Integrity Management


The Pipeline Safety Improvement Act of 2002 requires operators of transmission pipelines to establish an integrity management program in high density population areas. The U.S. Department of Transportation (DOT) subsequently issued a rule for integrity management of gas transmission pipelines in high-consequence areas, which became effective on February 14, 2004. Baseline assessments for covered pipelines must be completed by December 17, 2012. Reassessments for covered pipelines must be conducted within 7 years.


Safety Records


Natural gas travels through a 2.3 million mile delivery system for use in homes and businesses. The safety record of this system and the natural gas utilities is outstanding and it keeps getting better.


Plastic Pipe Database Collection Initiative

A group of representatives of federal and state regulatory agencies and the natural gas and plastic pipe industries have come together and formed The Plastic Pipe Data Collection Initiative (PPDC).


PPDC Forms

These are the downloadable forms to submit data to the PPDC and to volunteer. 

Please use the Negative Report Form when you have no failures to report and still want to remain an active submitter.


These PPDC Definitions explain how to complete the report form (see below for download link)



AGA designates a number of awards and commendations each year. Learn more about them here.


2007 Safety Leadership Summit

On December 5-6, 2007, AGA was pleased to host its first Safety Leadership Summit for its members to come together and discuss the state of the natural gas industry in 4 critical areas of safety:

1. Employee Safety
2. Utility Contractor Safety
3. Pipeline Safety
4. Public Safety


Distribution Integrity Management Program (DIMP)

AGA will continue its advocacy efforts on this critical issue to ensure the final regulation is reasonable, practicable, and cost-effective for operators.

2006 Safety Statistics Report

Click on the document below to access the 2006 Natural Gas Utility and Transmission Industry Occupational Injury and Illness Statistics as authored by AGA's Safety & Occupational Health Committee (PDF):



2007 Safety Statistics Report

This is an annual report of the natural gas utility and transmission industry occupational injuries and illnesses and motor vehicle stats as submitted to AGA, from member companies, for the year ending 2007.




Safety Alerts – including Federal Advisory Bulletins

PHMSA uses advisory bulletins to inform affected pipeline operators and Federal and state pipeline safety personnel of matters that have the potential of becoming safety or environmental risks.


2008 Safety Statistics Report

This is an annual report of the natural gas utility and transmission industry occupational injuries and illnesses and motor vehicle stats as submitted to AGA, from member companies, for the year ending 2007.



Natural gas utilities are part of the communities in which they operate, serving customers through an extensive pipeline system. Keeping our customers safe, secure and informed is paramount.


Member Generated Alerts

These Member Generated Alerts provide a means for AGA members to communicate quickly about operational, security or safety issues that may have an immediate or significant impact on natural gas distribution or transmission company operations. Alerts may include notices about an incident, security issue, or major action being taken by a member company that could impact, or be of significant interest, to others in the industry. Subscribers will be notified automatically as alerts are added and updated with additional information.


MAOP Verification and Pressure Testing for Transmission Pipelines

AGA developed this webpage to compile information available on MAOP record verification and testing. The information presented has been developed by AGA, government entities, and other pipeline safety stakeholders. The information is already in the public domain. AGA assertively supported the MAOP verification and testing provisions in the Pipeline Safety Act of 2011. The gas transmission pipeline structure is very complex. The diversity of the transmission pipe is so complex that no single process will provide solutions for every pipeline operator.
