C. Singer\nVice President of Operations\nThe Gas Service Company\n700 Scarritt Building\nKansas City, MO 64142\nDear Mr. Singer:\nIn your letter of September 24, 1973, you requested an interpretation of Paragraph 192.357(d),\nTitle 49, Code of Federal Regulations, which reads as follows:\n\"Each regulator that might release gas in its operation must be vented to the outside\natmosphere.\"\nYour specific question was whether the above paragraph requires an outside vent on service\nregulators which are installed inside, and which are not equipped with relief facilities. Since they\ndo not release gas in their operation, you have considered such regulators as constituting a closed\nsystem.\nYour interpretation is correct. Since there is no release of gas in the operation of such a service\nregulator, that regulator need not be vented to the outside atmosphere.\nIf we may assist further, please let us know.\nSincerely,\n\\signed\\\nJoseph C. Caldwell\nDirector\nOffice of Pipeline Safety\ndal\\192\\357\\73-10-12\n1","truncated":false,"body_characters":1033}
