It is your understanding that special\nprovision 336 was added to the HMR in a final rule published on March 18, 2014 [79 FR 15033]\nunder Docket No. PHMSA-2011-0158 (HM-233C), which adopted the terms of Special Permit\n(SP) DOT-SP 11836 as an alternative packaging method than what is required in §§ 173.24(g)\nand 173.24a(b)(4). You seek confirmation that it was not the Pipeline and Hazardous Materials\nSafety Administration’s (PHMSA) intent to require the operational controls in special provision\n336 to apply to packagings meeting the requirements of §§ 173.24(g) and 173.24a(b)(4).\nYour understanding is correct. In the HM-233C final rule, PHMSA adopted DOT-SP 11836 as\nnew special provision 336. As stated in the HM-233C final rule, “DOT-SP 11836 authorizes the\ntransportation of specific ammonia solutions in specification UNIH1 drums, UN3H1 jerricans,\nand UN6HA1 composite packagings that do not meet the provisions in §§ 173.24(g) and\n173.24a(b)(4). Specific operational controls are required in lieu of compliance with these two\nrequirements.”\n\n<<<PAGE 2>>>\n\nTherefore, packagings for specific ammonia solutions such as “UN2672, Ammonia solution, 8,\nPG III” that meet the provisions of §§ 173.24(g) and 173.24a(b)(4) are not required to meet the\noperational controls of special provision 336.\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nT. Glenn Foster\nChief, Regulatory Review and Reinvention Branch\nStandards and Rulemaking Division\n\n<<<PAGE 3>>>\n\nEdmonson\n21-0045\nFrom: INFOCNTR (PHMSA)\nTo: Dodd, Alice (PHMSA)\nSubject: FW: Interpretation of Special Provision 336 in 172.102\nDate: Friday, April 23, 2021 3:46:52 PM\nAttachments: PHMSA Interpretation request.pdf\nHi Alice,\nPlease see the attached interpretation request.\nLet me know if you need anything else from us.\nRegards,\n-Breanna\nFrom: Thomas Grego [mailto:Thomas.Grego@milport.com]\nSent: Thursday, April 22, 2021 8:01 PM\nTo: PHMSA HM InfoCenter <PHMSAHMInfoCenter@dot.gov>\nSubject: Interpretation of Special Provision 336 in 172.102\nCAUTION: This email originated from outside of the Department of Transportation (DOT).
