§193.2181. Impoundment capacity: LNG storage tanks.
49 C.F.R. § 193.2181
Each impounding system serving an LNG storage tank must have a minimum volumetric liquid impoundment capacity of:
110 percent of the LNG tank's maximum liquid capacity for an impoundment serving a single tank;
100 percent of all tanks or 110 percent of the largest tank's maximum liquid capacity, whichever is greater, for the impoundment serving more than one tank; or
If the dike is designed to account for a surge in the event of catastrophic failure, then the impoundment capacity may be reduced to 100 percent in lieu of 110 percent.
