Sec. 9.
(a) The filling densities for nonrefrigerated containers shall not exceed the following:
Aboveground | |
(1) Uninsulated | 56%* |
(2) Insulated | 57% |
(3) DOT containers shall be filled in accordance with DOT regulations. |
*This corresponds to 85% by volume at 5°F and to 90.6% by volume at 60°F.
(b) The filling density for refrigerated storage tanks shall be such that the tanks will not be liquid full at a liquid temperature corresponding to the vapor pressure at the start-to-discharge pressure setting of the pressure relief valve.
(c) If containers are to be filled according to liquid level by any gauging method other than a fixed length dip tube gauge, each container shall have a thermometer well so that the internal liquid temperature can be easily determined and the amount of liquid and vapor in the container corrected to a sixty (60) degrees Fahrenheit basis.
