These changes are necessary to recognize recent editions of certain matter incorporated by reference, to eliminate certain inconsistencies and typographical errors, and to reinstate a shipping description. The intended effect of these regulatory changes is to improve clarity and, consequently, reduce confusion. DATES: Effective: July 5, 1994. Compliance date: Compliance with the regulations, as amended herein, is authorized immediately. Incorporation by reference: The incorporation by reference of certain publications listed in this final rule is approved by the Director of the Office of the Federal Register as of July 5, 1994. FOR FURTHER INFORMATION CONTACT: Diane LaValle, (202) 366-4488, Office of Hazardous Materials Standards, Research and Special Programs Administration, U.S. Department of Transportation, Washington, DC 20590-0001. SUPPLEMENTARY INFORMATION: This final rule makes changes to the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180) based on either requests from industry or agency initiative. These changes clarify and correct certain inconsistencies appearing in the HMR, add a specific shipping description currently authorized by approval, and update certain standards incorporated by reference under Sec. 171.7. These changes impose no new requirements on persons subject to the HMR and do not adversely affect safety. The following is a discussion of the changes made under this final rule.#

Passage 2RSPA received several requests to update various standards currently incorporated by reference in the table contained in Sec. 171.7(a)(3). These standards are as follows:#

Passage 3The Oak Ridge Institute for Science and Education requested RSPA to incorporate into the HMR the latest American National Standards Institute, Inc. (ANSI) pamphlet, ANSI N14.1-1990, entitled ``Uranium Hexafluoride--Packaging for Transport.'' Incorporating the 1990 edition of the standard into the HMR will enhance uranium hexafluoride transportation safety by recognizing the use of packagings fabricated to certain updated industrial specifications and standards. The 1990 standard also contains specific information on the reuse of valves and various editorial clarifications. Section 173.420 of the HMR permits uranium hexafluoride to be transported in packagings designed, fabricated, inspected, tested and marked in accordance with certain DOT and industry standards that include packagings fabricated to the ANSI N14.1 (1987, 1982, or 1971 edition) in effect at the time the packaging was manufactured. This section also provides that, before initial filling and during periodic inspection and test, the packagings must be cleaned in accordance with the ANSI N14.1 requirements. The American Pyrotechnic Association (APA) petitioned (P-1174) to update APA Standard 87-1, entitled ``Standard for Construction and Approval for Transportation of Fireworks and Novelties,'' from the September 1987 edition to the April 1993 edition. APA Standard 87-1 contains procedures for construction and approval for transportation of new fireworks and novelty items. In the revised standard, the shipping descriptions, hazard classes, and section references are consistent with the current HMR. The revised standard also has been expanded to offer guidance on conducting the fireworks stability test, and to address packaging requirements, EX-number markings, and transitional provisions. The Association of American Railroads (AAR) petitioned (P-1193) to update ``AAR Manual of Standards and Recommended Practices, Section C--Part III, Specification for Tank Cars, Specification M- 1002,'' from the 1988 edition to the September 1, 1992 edition. The revised AAR publication contains updated discussions of matters such as repair of cracks, weld overlay, inspection of rubber-lined tank cars, and the renewal of approvals for valves and fittings. The Compressed Gas Association (CGA) petitioned (P-1196) to update CGA Pamphlet C-7, entitled ``A Guide for the Preparation of Precautionary Markings for Compres#

Passage 4sed Gas Containers, appendix A,'' from the April 15, 1983 edition to the 1992 (sixth) edition. In the 1992 edition, revisions have been made to the shipping descriptions for consistency with the current HMR. The Institute of Makers of Explosives (IME) petitioned (P-1171) to update IME Safety Library Publication 22 (IME Standard 22) entitled ``Recommendation for the Safe Transportation of Detonators in a Vehicle with Certain Other Explosive Materials,'' from the January 1, 1985 edition to the May 1993 edition. This standard contains information relative to the use and construction of IME-22 containers or compartments for the transport of certain detonators. Section 173.63 authorizes the use of these containers and compartments for packaging detonators and Sec. 177.835(g) authorizes the transportation of these packages on the same transport vehicle with other explosives. The IME standard is used extensively by safety personnel in the commercial explosives industry for training purposes and by users of explosives. In the revised standard, the shipping descriptions, hazard classes, and section references have been revised for consistency with recent changes to the HMR. RSPA has reviewed these updated standards. RSPA found no provisions that would impose additional requirements and agrees that they should be incorporated by reference. With regard to the AAR standards referenced in Sec. 171.7, the table contains separate entries for ``AAR Specification for Tank Cars, Specification M-1002, 1988'' and ``AAR Specification for Tank Cars, Specification M-1002, Section C--Part III, September 1988,'' which are the same standard. The first entry is removed, and the second entry is revised to clarify that this standard is contained in the AAR Manual of Standards of Recommended Practices. These changes were proposed under a separate rulemaking action [Docket HM-197; May 7, 1993; 58 FR 27257] and were supported by commenters. They are merely finalized under this docket.#

Passage 5IME and several explosives companies jointly petitioned (P-1143) to amend the Hazardous Materials Table (the Table) in Sec. 172.101 to reinstate an entry for ``Ammonium nitrate fertilizer, UN2067.'' This shipping description was one of six entries for ammonium nitrate fertilizers removed from the Table under a revised final rule issued December 20, 1991 [Docket HM-181; 56 FR 66124]. Although these descriptions are contained in the United Nations' Recommendations on the Transport of Dangerous Goods (UN Recommendations), they were removed because RSPA found them confusing and difficult to use. However, petitioners assert that this shipping description, ``Ammonium nitrate fertilizer, UN2067,'' has been used widely for many years and the domestic industry has relied upon the ``Definition and Test Procedures for Ammonium Nitrate Fertilizer,'' published by The Fertilizer Institute, to ensure the stability of their material. Petitioners stated that their vehicle placards, shipping papers, and industry training procedures, including emergency response training, rely on the identification number ``2067.'' They asserted that it would be a questionable expenditure of time and money for them to convert their placards, documents and training procedures to show a different identification number. RSPA agrees with the petitioners that adequate justification exists for reauthorizing the description ``Ammonium nitrate fertilizer, UN2067.'' RSPA issued an approval (CA 93-10006) authorizing use of the description ``Ammonium nitrate fertilizer, UN2067'' not meeting Class 1 (explosive) criteria. Therefore, in this final rule, ``Ammonium nitrate fertilizer, 5.1, UN2067, III'' is added to the Table, subject to Special Provision 23. RSPA is also adding Special Provision 23 in Sec. 172.102(c)(1) stipulating that material shipped or transported under this description may not meet Class 1 (explosive) criteria. Amalgamet Canada petitioned (P-1171) to amend the entry ``Titanium Tetrachloride'' in the Table by removing Special Provision N41, which does not allow any packaging material to be made of metal construction. RSPA agrees that removal of N41 would eliminate an inconsistency with Special Provisions B32 and T45, which allow the use of certain containers made of stainless steel. RSPA is amending Special Provision B13 to extend the September 1, 1993 date for construction of cargo tank#

Passage 6s that are equivalent to MC 306 cargo tank specifications until August 31, 1995. This change is consistent with a final rule authorizing the continued construction of MC 306 cargo tanks until August 31, 1995 [Docket HM-183, January 12, 1994; 59 FR 1784]. Paragraph (e)(15)(i) was revised under Docket HM-166X [58 FR 50496; September 27, 1993] to allow DOT 3A and 3AA cylinders over 35 years old to be retested every 10 years rather than every five years, provided they were manufactured after December 31, 1945. However, Sec. 173.34(e)(15)(v) continues to allow only cylinders less then 35 years old to be stamped with a five-point star showing that these cylinders may be tested every 10 years. Therefore, in this final rule, Sec. 173.34(e)(15)(v) is revised, for consistency with paragraph (e)(15)(i), to permit cylinders manufactured after December 31, 1945, to be stamped with a five-point star. Also, because cylinders manufactured on or before December 31, 1945, do not qualify for a ten- year retest period under these provisions, the wording of paragraph (e)(15)(i) has been simplified. Paragraph (e)(17) requires DOT 8 and 8AL acetylene cylinders to be requalified, on a phase-in basis, in accordance with CGA Pamphlet C-13. Because many acetylene cylinder owners voluntarily complied with CGA Pamphlet C-13 prior to issuance of the final rule, RSPA granted an exception, in paragraph (e)(17)(ii), for all cylinders requalified and marked in accordance with the CGA pamphlet before January 15, 1993. The time required for RSPA to implement the registration procedures for acetylene cylinder retesters resulted in a backlog of requests. To alleviate unnecessary burdens to industry, RSPA has allowed retesters to continue requalifying and marking the cylinders in accordance with CGA Pamphlet C-13. Accordingly, the date in paragraph (e)(17)(ii) is revised to reflect an extension to October 1, 1994. In paragraph (b), in Note 9 following the ``Organic Peroxides Table,'' the reference to ``Sec. 173.225(e)(3)(v)'' is corrected to read ``Sec. 173.225(e)(3)(ii).''#

Passage 7In revisions to a final rule concerning the transport of elevated temperature materials [Docket HM-198A; 58 FR 3344; January 8, 1993], RSPA revised the bulk packaging requirements for the transport of asphalt by highway in Sec. 173.247. In paragraph (g)(1)(iii)(B), to ensure that a reclosing pressure relief device is not rendered inoperable by viscous lading, RSPA allowed an opening with a maximum three-inch nominal pipe diameter. The maximum effective area of the opening was incorrectly given as 46 cm\2\ (7.1 in\2\). The correct maximum effective area is 48 cm\2\ (7.4 in\2\). This final rule corrects this error. Sections 173.302(h) and 173.304(g) provide that mixtures meeting Division 2.3, Hazard Zone A, must conform to Sec. 173.40. These provisions are revised to clarify that Sec. 173.40 applies to a pure gas, as well as a gas mixture, meeting Division 2.3, Hazard A. In a final rule published on December 20, 1991 [Docket HM-181; 56 FR 66124], RSPA revised the limited quantity provisions in Sec. 173.306(b)(3) to include Division 6.1 Packing Group III materials. Through an oversight, a similar revision was not made to the aerosol provisions contained in paragraph (a)(3). Therefore, in this final rule, RSPA is amending paragraph (a)(3) by adding the phrase ``(other than a Division 6.1 Packing Group III material).'' In paragraph (a)(2)(i), the 1990 revision of ANSI N14.1 is added to the earlier editions of ANSI N14.1 cited in this paragraph. Also, in paragraph (b), the reference to ANSI Standard N14.1-1987 is updated to 1990. These changes are made for consistency with the incorporation by reference of the 1990 edition of this standard under this final rule. The example provided in paragraph (c) is revised by adding the wording ``PG II'' to reflect a complete basic description, as stated in the sentence preceding the example.#

Passage 8The 17th Session of the UN Committee of Experts on the Transportation of Dangerous Goods adopted amendments for incorporation in the eighth revised edition of the UN Recommendations. One amendment provides that UN markings on certain steel drums must include the thickness of the packaging material to the nearest tenth of a millimeter; however, the amendment does not require the marking to contain a unit of measurement (i.e., ``mm''). Section 178.503(a)(9) states that the marking must include the ``mm'' abbreviation for millimeters as part of the thickness marking for metal and plastic drums and jerricans intended for reuse or reconditioning as single packagings or the outer packagings of composite packagings. For consistency with the eighth revised edition of the UN Recommendations, paragraph (a)(9) is revised to clarify that the marked thicknesses must be shown to the nearest tenth of a millimeter and to reflect that the ``mm'' abbreviation is not required. Recognizing that some manufacturers may choose to include the ``mm'' abbreviation or may already be including the ``mm'' in drums markings, the provision allows marking of the ``mm'' symbol on a permissive basis. Corresponding minor editorial changes are made to the UN marking examples shown in paragraphs (d)(2)(ii) and (d)(3). In Sec. 178.505, a typographical error is corrected in the last sentence of paragraph (b)(1) by changing the reference from ``Sec. 178.503(a)(10)'' to ``Sec. 178.503(a)(9).'' In Sec. 178.506, a typographical error is corrected in the last sentence of paragraph (b)(1) by changing the reference from ``Sec. 178.503(a)(10)'' to ``Sec. 178.503(a)(9).'' In Sec. 178.509, a typographical error is corrected in the last sentence of paragraph (b)(4) by changing the reference from ``Sec. 178.503(a)(10)'' to ``Sec. 178.503(a)(9).'' In Sec. 178.511, a typographical error is corrected in the last sentence of paragraph (b)(1) by changing the reference from ``Sec. 178.503(a)(10)'' to ``Sec. 178.503(a)(9).'' In Sec. 178.601, a typographical error is corrected in the first sentence of paragraph (g)(7) by changing the reference from ``Sec. 178.601 (g)(1) and (g)(2)'' to ``Sec. 178.601 (g)(1) through (g)(6).''#

Passage 9In Sec. 178.605, a typographical error is corrected in the last sentence of paragraph (b) by changing the reference from the ``Associate Administrator of Hazardous Materials Safety'' to ``Associate Administrator for Hazardous Materials Safety.'' In Sec. 178.606, a typographical error is corrected in the third sentence of paragraph (b) by changing the reference from the ``Associate Administrator of Hazardous Materials Safety'' to ``Associate Administrator for Hazardous Materials Safety.'' In Sec. 179.105-7, in paragraph (b), the reference to the 1976 edition of the AAR Specifications for Tank Cars is updated to reference the September 1, 1992 edition. This final rule will facilitate compliance with the HMR by correcting errors, clarifying provisions and updating obsolete matter incorporated by reference. All of the changes are noncontroversial. With regard to matter incorporated by reference, there is a need to update IME Standard 22 as quickly as possible to avoid misunderstandings that can adversely affect the safe transportation of detonators. Other provisions of this rule provide minor relief from regulatory provisions which will have an immediate benefit to the affected entities. For these reasons, RSPA has determined that public notice and comment procedures, prior to adoption of this final rule, are not required under the Administrative Procedure Act (5 U.S.C. 551 et seq.). A. Executive Order 12866 and DOT Regulatory Policies and Procedures This final rule is not considered a significant regulatory action under section 3(f) of Executive Order 12866 and, therefore, was not subject to review by the Office of Management and Budget. The rule is not considered significant under the regulatory policies and procedures of the Department of Transportation (44 FR 11034; February 26, 1979). The impacts of the changes are so minimal that a regulatory evaluation is unnecessary.#

Passage 10This final rule has been analyzed in accordance with the principles and criteria in Executive Order 12612 (``Federalism''). The Hazardous Materials Transportation Act contains express preemption provisions (49 App. U.S.C. 1811) that preempt a non-Federal requirement if (1) compliance with both the non-Federal and the Federal requirement is not possible; (2) the non-Federal requirement creates an obstacle to accomplishment of the Federal law or regulations; or (3) it is preempted under 49 App. U.S.C. 1804(a)(4), concerning certain covered subjects, or 49 App. U.S.C. 1804(b), concerning highway routing. Covered subjects are: (i) The designation, description, and classification of hazardous materials; (ii) The packing, repacking, handling, labeling, marking, and placarding of hazardous materials; (iii) The preparation, execution, and use of shipping documents pertaining to hazardous materials and requirements respecting the number, content, and placement of such documents; (iv) The written notification, recording, and reporting of the unintentional release in transportation of hazardous materials; or (v) The design, manufacturing, fabrication, marking, maintenance, reconditioning, repairing, or testing of a package or container which is represented, marked, certified, or sold as qualified for use in the transportation of hazardous materials. This rule concerns the description and handling of hazardous materials. This rule preempts State, local, or Indian tribe requirements in accordance with the standards set forth above. The HMTA (49 App. U.S.C. 1804(a)(5)) provides that if DOT issues a regulation concerning any of the covered subjects after November 16, 1990, DOT must determine and publish in the Federal Register the effective date of Federal preemption. That effective date may not be earlier than the 90th day following the date of issuance of the final rule and not later than two years after the date of issuance. RSPA has determined that the effective date of Federal preemption for the requirements in this rule concerning covered subjects is October 1, 1994. Thus, RSPA lacks discretion in this area, and preparation of a federalism assessment is not warranted.#

Passage 11I certify that this final rule will not have a significant economic impact on a substantial number of small entities. This rule relaxes certain provisions that apply to hazardous materials shippers, carriers and packaging manufacturers, some of whom are small entities. This final rule should result in minor cost savings to affected entities. It also reduces confusion by incorporating by reference the latest editions of certain standards that have been revised for consistency with the current HMR. There are no new information collection requirements in this final rule. A regulation identifier number (RIN) is assigned to each regulatory action listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. The RIN number contained in the heading of this document can be used to cross-reference this action with the Unified Agenda.
