30°F
The foundation design and the container, bottom insulation shall prevent damage to the container from
Frost heave
If the refrigerated LP gas container under bottom, foundation and insulation are in contact with the soil, and the seal temperature could be less than 32°F, a heating system shall be installed to prevent the soil temperature from falling below
32°F
The underground heating system shall be designed to allow both functional
And performance monitoring
The underground temperature shall be observed, and
Logged at least weekly
Where the foundation has a discontinuity, such as bottom piping, the heating system, and that zone
Shall be designed for the discontinuity
The under container heating system shall be installed so that any heating elements or temperature sensors used for the control can be replaced while the container is

Not to exceed five years
The pressure relief devices shall be seized to relieve the flow capacity, determined for the largest single contingency and for reasonable and probable combination of the following contingencies
Fire exposure, operational, upset, vapor displacement during filling, flash, vaporization during filling, loss of refrigeration, heat input from pump, recirculation, drop in barometric pressure
