Specifically, you ask whether the HMR apply to the transportation of a Division 2.2 and\n5.1 gas having a pressure in a container below 200 kPa (29.0 psig/43.8 psia). We apologize for the\ndelay in responding and any inconvenience this may have caused.\nPHMSA revised the definition in § 173.115(b)(1) for a Division 2.2 gas in final rules issued on\nJanuary 14,2009 and January 4, 2010. Section 173.115(b) states a Division 2.2 gas is a nonflammable,\nnon-poisonous compressed gas that includes compressed gas, liquefied gas, pressurized\ncryogenic gas, compressed gas in solution, asphyxiant gas, and oxidizing gas. Therefore, as\namended, a Division 2.2 gas, including one with an oxidizer subsidiary hazard, is one that exerts a\ngauge pressure on a packaging of at least 200 kPa at 20°C (68 OF). In accordance with the revised\ndefinition, after January 1, 2010, a cylinder of oxygen gas that exerts a gauge pressure less than\n200 kPa at 20°C is not subject to the HMR. See Docket Nos. PHMSA-2007-0065 (HM-224D)\nand PHMSA-2008-0005 (HM-215J) (74 FR 2200 and 75 FR 63).\nYou also note that the definition in § I 73.29(b)(2)(iv)(B) for an empty container of Division 2.2 gas\nwas not revised to reflect the new lower limit of 200 kPa at 20°C in § 173.115(b)(1), and ask if this\nis an error. It is. We thank you for bringing this matter to our attention and again apologize for any\ninconvenience this may have caused. We made this correction in the January 4, 2010 final rule we\ndiscussed in the previous paragraph.\nI hope this satisfies your request.\nSincerely,\n~~vn~~-';7~~\"--\n/ /\nT.
