Natural Gas Pipelines

Natural Gas Pipeline

The Natural Gas Pipeline Safety Act of 1968 authorizes the Department of Transportation to regulate pipeline transportation of flammable, toxic, or corrosive natural gas and other gases as well as the transportation and storage of liquefied natural gas. Natural gas supplies 25 percent of all the energy Americans consume. It's our second largest source of energy.

PHMSA develops and enforces regulations for the safe, reliable, and environmentally sound operation of the nation's 2.6 million mile pipeline transportation system and the nearly 1 million daily shipments of hazardous materials by land, sea, and air.
