LNG Rail Tank Steel Thickness Fix

If you build or operate liquefied natural gas (LNG) rail tanks, the rule corrects minimum steel thickness requirements: the outer jacket shell must be at least 7/16 inch after forming, and the outer jacket heads must be at least 1/2 inch after forming and made from the steel specified in Sec. 179.16(c). This correction is effective immediately.
