Specifically, you ask whether it was the Pipeline and Hazardous Materials Safety\nAdministration's (PHMSA) intent to reduce the design margin (safety factor) for UN portable\ntanks when it incorporated by reference (IBR) the 2015 Edition of the American Society of\nMechanical Engineers Boiler and Pressure Vessel Code (ASME Code) into the HMR on May 31,\n2016, in the final rule titled \"Incorporation by Reference Edition Update for the American\nSociety of Mechanical Engineers Boiler and Pressure Vessel Code and Transportation Systems\nfor Liquids and Slurries: Pressure Piping Code\" [Docket No. PHMSA-2015-0271 (HM-261)].\nYou cite a letter of interpretation issued by this Office to Mr. Mike Pitts on July 1, 2016, that\nacknowledges the reduced design margin allowed in the 2015 ASME Code (3.5:1) was not\napplicable to U.S. Department of Transportation (DOT) specification cargo tanks unless under\nthe terms of a special permit.\nAs prescribed in § 178.273 of the HMR, UN portable tanks must be designed, constructed,\ncertified, and stamped in accordance with the requirements in Division I, Section VIII, of the\nASME Code IBR in § 171.7. Further, the reduced design margin prescribed in Division I,\nSection VIII, of the 2015 ASME Code (3.5:1) is authorized for UN portable tanks. Thus, the\nreduced design margin restriction applicable to DOT specification cargo tanks does not apply to\nUN portable tanks manufactured in accordance with Division I, Section VIII, of the 2015 ASME\nCode. The IBR, however, does not include changes to currently adopted ASME Boiler and\nPressure Vessel Code rules (i.e., code cases). Any variation from the HMR would require a\nspecial permit from PHMSA.\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nT.

Pitts of\nMississippi Tank (copy attached for your easy reference).\nEssentially, I have the same question for UN portable tanks. When incorporating by reference the 2015 Edition\nof the ASME Code, did PHMSA intend to accept the reduction of the safety factor (design margin) from 4:1\n(1998 ASME) to 3.5:1 (2015 ASME). Further, does PHMSA automatically accept ASME Code Cases when issued\nby ASME?\nFor cargo tanks, based upon your letter to Mr. Pitts, the answer was apparently \"no\". For portable tanks,\nPHMSA's past policy was to require a Special Permit to allow a 3.5:1 design margin and to allow a Code Case.\nAs only one example, 1 refer you to SP 16133 issued to Cryovat. This Special Permit authorizes a design margin\nof 3.5:1 and therefore the use of Code Case 2596 concerning the cold stretching of austenitic stainless steels.\nThe presumption has always been that potable tanks see significant external loads due to transportation in\naddition to pressure loads. The ASME Code addresses them vaguely or generally, while DOT addresses them\nspecifically in 49CFR178.273(c). There is also the issue of existing (already-approved) designs and whether the\npressure vessel wall can be thinned (based upon 3.5:1) without re-analyses or re-approval.\nAs for Code Cases, some jurisdictions accept them automatically, some do not. The issue here is that ASME,\nwhen issuing a Code Case, has in no way taken into consideration that UN portable tanks are used in\ntransportation and that they are used in hazardous material service.\nWe look forward to your reply to the above.\nSincerely,\nAris Antoniou\nGold Tank Inspection Service Inc.\nPO Box 5638, Kingwood, TX 77325\nTel: 281 913 8382; Fax: 281 913 8384; email: goldserviceusa@aol.com\n\n<<<PAGE 5>>>\n\nMississippi Tank Company\nPost Office Drawer 1391\nHattiesburg, Mississippi 39403-1391\nRE: Docket No. PHMSA-2015-0271 (HM-261)\nDear Mr. Pitts:\nThank you for your comment to the direct final rule for the incorporation by reference (IBR)\nof the 2015 Edition of the American Society of Mechanical Engineers Boiler and Pressure\nVessel Code (ASME Code), which was filed in the aforementioned docket on May 31, 2016.\nThank you as well for your subsequent email correspondence and phone conversation with\nJoseph Solomey, our Senior Assistant Chief Counsel for Hazardous Materials Safety. Your\ncomments were submitted timely and we do not view them as adverse for the reasons\ndiscussed below.\nIn your comment you express concerns that the Pipeline and Hazardous Materials Safety\nAdministration (PHMSA) is allowing the higher allowable stresses in the newer editions of\nthe ASME Code for specification cargo tanks. You rightfully point out that the current (2015)\nEdition of the ASME Code, Section VIII allows higher allowable stresses, resulting in a\ndesign margin of 3.5:1, compared to a design margin of 4:1 in the 1998 edition. You have\nhighlighted three sections of the Hazardous Materials Regulations, 49 C.F.R. §$178.337-\n3(a)(1), 178.345-3(a)(1) and 178.338-3(a)(1), all of which contain similar, but not exact\nverbiage. Although the verbiage is not identical, it is PHMSA's position that all three of these\nsections require the manufacturer to build a specification cargo tank to the 4:1 design margin.\nThis direct final rule maintains the design margin of 4:1 for DOT specification cargo tanks\nmanufactured to ASME Code Section VIII. PHMSA may revisit the verbiage in 49 C.F.R.\n§§178.337-3(a)(1), 178.345-3(a)(1) and 178.338-3(a)(1) in a future rulemaking to clarify any\nconfusion outlined within your comments surrounding allowable stresses. We sincerely\nappreciate your support for this rulemaking and for PHMSA's efforts in updating the ASME\nCode in the Hazardous Materials Regulations.\nSincerely,\nMr. Charles E.
