D.C. 20590\nDr. Jianke Wang\nSenior Project Manager\nNational Oilwell Varco\n2800 N. Frazier St.\nConroe, TX 77303\nRef. No. 10-0054\nDear Dr. Wang:\nThis responds to your March 5, 20lO email and subsequent telephone discussion with a member\nofmy staff regarding requirements for the continued use ofDOT Specification 1M 101 and 102\nportable tanks for transportation of diesel fuel, with a flashpoint of about 140°F, under the\nHazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask about\nthe impact ofthe transitional period provided in § 171.14(d)(4) after January 1, 20lO. You state\nthese 1M portable tanks will be in full conformance with the requirements in § 173.32(c)(2) and\nwill occasionally be transported by vessel to offshore drilling sites.\nThe obsolete provision in § 171. 14(d)(4) allowed for a hazardous material to be transported until\nJanuary 1, 2010 in an 1M portable tank in accordance with the T codes (special provisions)\nassigned to the hazardous material in the § 172.101 Hazardous Materials Table (HMT) in effect\non September 30, 2001. 1M portable tanks now are required to meet the applicable special\nprovisions appearing in the current HMT.\nDiesel fuel, UN1202, is listed in the HMT and assigned Special provisions B 1, T2 and TP 1 in\nColumn (7). The B 1 code provides that, for a hazardous material with a flashpoint between\nlOO°F and 200°F, the bulk packagings listed in § 173.241 may be used. Paragraph (c) of that\nsection authorizes use of 1M portable tanks. The T2 code specifies the tank's minimum test\npressure, minimum shell thickness, bottom opening and pressure relief requirements. The TP 1\ncode prescribes filling density requirements. These specific code requirements are contained in\n§ 172.1 02( c )(7) and (c )(8), respectively.\nI hope this information is helpful. If you have further questions, please contact this office.\nSincerly,\n4L~~\nCharles E. Betts\nChief, Standards Development\nOffice ofHazardous Materials Standards\n\n<<<PAGE 2>>>\n\nDrakeford, Carolyn (PHMSA)\nFrom: INFOCNTR (PHMSA)\nSent: Friday, March 05,201011:42 AM\nTo: Drakeford, Carolyn (PHMSA)\nSubject: FW: Request for Formal interpretations to diesel transportation in 1M portable tanks after\nJanuary 1, 2010.\nFrom: Wang, Jianke [mailto:Jianke.Wang@nov.com]\nSent: Friday, March 05, 2010 11: 10 AM\nTo: INFOCNTR (PHMSA)\nSubject: Request for Formal interpretations to diesel transportation in 1M portable tanks after January 1/ 2010.\nDear SirlMadam,\nWe have some DOT 1M101 and 1M1 02 portable tanks. The transporting liquid is diesel fuel.\nAs I am reading the Dot CFR 49 code, I have some questions about the continued use ofthese existing 1M\nportable tanks.\n§ 173.32 Requirements for the use of portable tanks.\n(c) Grandfather provisions for portable tanks -(2) A DOT Specification 51. 1M 101. or 1M 102 portable tank may not be manufactured after January 1, 2003; however, such\ntanks may continue to be used for the transportation of a hazardous material provided they meet the requirements of this subchapter, including the specification requirements\nand the requirements of this subchapter for the transportation of the particular hazardous material according to the T codes in effect on September 30, 2001 or the new T\ncodes in §172.1 02(c)(7)(i) (see §171.14(d)(4) for transitional provisions applicable to T codes), and provided the portable tanks conform to the periodic inspection and tests\nspecified for the particular portable tank in subpart G of part 180 of this subchapter. After January 1, 2003, all newly manufactured portable tanks must conform to the\nrequirements for the design, construction and approval of UN portable tanks as specified in §§178.273, 178.274,178.275,178.276,178.277 and part 180, subpart G, of this\nsubchapter.\n§ 171.14 Transitional provisions for implementing certain requirements.\n(d) (4) Until January 1,2010, a hazardous material may be transported in an 1M, IMO, or DOT Specification 51 portable tank in accordance with the T Codes (Special\nProvisions) assigned to a hazardous material in Column (7) of the §172.101 Table in effect on September 30, 2001.\nWhat will the § 171.14 (d)( 4) affect our continued use of these existing 1M portable tanks provided all the\nconditions specified in § 173.32 (c )(2) are satisfied?\nThanks in advance for your helps.\nBest regards,\nJianke Wang, Ph.D., P.E.\nSenior Project Engineer\nNational Oilwell Varco\n2800 N Frazier St\nConroe, TX 77303\nTel: 936-523-2634\nFax:936-523-2788\n1","truncated":false,"body_characters":4625}
