Oil & Gas Journal - September 7, 2015

Reports for 2014 show an increase in FERC-defined major gas pipeline companies: 93 companies of 165 filing for 2014, from 92 of 163 for 2013.

For several years after 1984, many non-majors did not describe their systems. But filing descriptions of their systems has become standard, and most provide miles operated.
