Liquefied Natural Gas Security and Hazards

Liquefied natural gas (LNG) is a hazardous fuel shipped in large tankers from overseas to U.S. ports. Because LNG infrastructure is highly visible and easily identified, it can be vulnerable to terrorist attack. Since September 11, 2001, the U.S. LNG industry and federal agencies have put new measures in place to respond to the possibility of terrorism. Nonetheless, public concerns about LNG risks continue to raise questions about LNG security. Faced with a perceived national need for greater LNG imports, and persistent public concerns about LNG risks, some in Congress are examining the adequacy of security provisions in federal LNG regulation. LNG infrastructure consists primarily of tankers, import terminals, and inland storage plants. There are nine active U.S. terminals and proposals for many others. Although potentially catastrophic events could arise from a serious accident or attack on such facilities, LNG has a record of relative safety for the last 40 years, and no LNG tanker or land-based facility has been attacked by terrorists. The likelihood and possible impacts from LNG attacks continue to be debated among experts.
