The structural members of an impoundment system must be designed and constructed to prevent impairment of the system's performance reliability and structural integrity as a result of the following:\n\n1. the imposed loading from:\n\na. full hydrostatic head of impounded LNG; [49 CFR 193.2155(a)(1)(i)]\n\nb. hydrodynamic action, including the effect of any material injected into the system for spill control; [49 CFR 193.2155(a)(1)(ii)]\n\nc. the impingement of the trajectory of an LNG jet discharged at any predictable angle; and [49 CFR 193.2155(a)(1)(iii)]\n\nd. anticipated hydraulic forces from a credible opening in the component or item served, assuming that the discharge pressure equals design pressure; [49 CFR 193.2155(a)(1)(iv)]\n\n2. the erosive action from a spill, including jetting of spilling LNG, and any other anticipated erosive action including surface water runoff, ice formation, dislodgement of ice formation, and snow removal; [49 CFR 193.2155(a)(2)]\n\n3. the effect of the temperature, any thermal gradient, and any other anticipated degradation resulting from sudden or localized contact with LNG; [49 CFR 193.2155(a)(3)]\n\n4. exposure to fire from impounded LNG or from sources other than impounded LNG; [49 CFR 193.2155(a)(4)]\n\n5. if applicable, the potential impact and loading on the dike due to:\n\na. of the component or item served or adjacent components; and [49 CFR 193.2155(a)(5)(i)]\n\nb. the LNG facility adjoins the right-of-way of any highway or railroad, collision by or explosion of a train, tank car, or tank truck that could reasonably be expected to cause the most severe loading. [49 CFR 193.2155(a)(b)(ii)]\n\nB. An LNG storage tank must not be located within a horizontal distance of one mile (1.6 km) from the ends, or 1/4 mile (0.4 km) from the nearest point of a runway, whichever is longer. The height of LNG structures in the vicinity of an airport must also comply with Federal Aviation Administration requirements in 14 CFR Section 1.1.
