Sider, A. and Friedman, N. November 2, 2016. More than half of U.S. Pipelines are at least 46 years old. Building new systems has become harder amid opposition from landowners and environmental groups. Wall Street Journal.

More than 60% of U.S. fuel pipelines were built before 1970, according to federal figures. Recent disruptions on Colonial Pipeline Co.’s fuel artery running up the East Coast show why some energy observers worry that this is a problem.  Carl Weimer, executive director of the advocacy group Pipeline Safety Trust, said fuel pipeline systems can operate safely for decades if they are well maintained. But after 40 or 50 years, problems like corrosion increase.
