Q What is INGAA? Posted12 years, 6 months and 21 days ago A Answered4 years, 1 month and 2 days ago Answered byJames O'Bryant The Interstate Natural Gas Association of America (INGAA) is a trade organization that advocates regulatory and legislative positions of importance to the natural gas pipeline industry in North America. INGAA is comprised of 25 members, representing the vast majority of the interstate natural gas transmission pipeline companies in the U.S. and comparable companies in Canada. INGAA’s members operate approximately 200,000 miles of pipelines, and serve as an indispensable link between natural gas producers and consumers. The interstate natural gas pipeline industry has two principal federal regulators: the Federal Energy Regulatory Commission (FERC) is responsible for the economic regulation of pipelines, while the U.S. Department of Transportation (DOT) Office of Pipeline Safety oversees the industry's safety efforts.
