If\nthis option is used, then the computation must be checked by\ndetermination of specific gravity of product after loading.\nSince anhydrous ammonia is not listed, the method involving\noutage tables and specific gravities is not an option.\nI hope this satisfies your request.\nSincerely,\nmn 7Balho\nDelmer F.

This regulation provides in its opening sentence that the amount of a liquefied gas\nloaded into a tank may be determined \"either by measurement or calculation of the weight.\"\nBased on these plain terms, our view is that the amount of any liquefied gas, including anhydrous\nregulation's third sentence, which discusses the manner in which the weight of certain\nammonia, can be verified either by measurement or calculation of its weight. In our view, the\nspecifically listed liquefied gases is to be calculated, merely defines the method in which the\namount of those listed liquefied gases are to be calculated and does not limit the calculation\noption provided to other liquefied gases by the regulation's first sentence. Further, we view the\nthe use of outage tables and specific gravities.\nregulation as allowing the calculation of the weight of anhydrous ammonia loaded into a tank by\nThese views are consistent with those offered to me by the RSPA hotline, which\nopined based on a preliminary review of the regulation that the amount of any liquefied gas can\nbe determined by calculation under this regulation. We request your confirmation that RSPA\ninterprets the regulation in the manner reported by the hotline and described above.\nWASHINGTON\nPHOENIX\nLOS ANGELES\nMOSCOW\nALMATY\n\n<<<PAGE 3>>>\n\nYour reply to this request at the earliest convenience would be greatly\nappreciated.
