Passage 1[Federal Register Volume 61, Number 90 (Wednesday, May 8, 1996)] [Rules and Regulations] [Pages 20747-20753] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 96-11297] ======================================================================= ----------------------------------------------------------------------- Research and Special Programs Administration [Docket No. HM-169A; Amdt. Nos. 172-143, 173-244, 174-80, 176-37] RIN 2137-AB60 Hazardous Materials Transportation Regulations; Compatibility with Regulations of the International Atomic Energy Agency AGENCY: Research and Special Programs Administration (RSPA), DOT. ACTION: Final rule; editorial revisions and response to a petition for reconsideration. ----------------------------------------------------------------------- SUMMARY: On September 28, 1995, RSPA published a final rule which amended the Hazardous Materials Regulations pertaining to the transportation of radioactive materials to harmonize them with those of the International Atomic Energy Agency (IAEA) and, thus, most major nuclear nations of the world. Several substantive changes were made to provide a more uniform degree of safety for various types of shipments. These changes included requiring offerors and carriers to maintain written radiation protection programs, revising the definition of and packaging for low specific activity radioactive materials, and requiring use of the International System of Units for the measurement of activity in a package of radioactive material. This final rule makes editorial and technical corrections to that final rule and responds to a petition for reconsideration. DATES: The effective date of these amendments is June 3, 1996. Immediate compliance with the amendments is authorized. The effective date for the final rule published under Docket HM- 169A on September 28, 1995 (60 FR 50292) remains April 1, 1996.

Passage 2On September 28, 1995, RSPA published a final rule under Docket HM- 169A (60 FR 50292) which amended the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) pertaining to the transportation of radioactive materials to harmonize them with those of the International Atomic Energy Agency's (IAEA's) Safety Series No. 6, ``Regulations for the Safe Transport of Radioactive Material Revised 1985 and Supplemented 1988 and 1990'' (IAEA SS6-85) and, thus, most major nuclear nations of the world. RSPA has received correspondence identifying errors and a petition for reconsideration in response to the final rule. This document incorporates editorial and technical revisions to the final rule based on the merits of the correspondence and other revisions that RSPA has determined are necessary to correct or clarify the final rule.#
Passage 3Section 172.101. In the Hazardous Materials Table, RSPA is correcting the shipping name for low specific activity material by adding the suffix ``n.o.s.''. For the shipping name for surface contaminated objects, RSPA is correcting the packaging references. Section 172.203. In the final rule, RSPA inadvertently removed the provision of Sec. 172.203(d)(1) which requires the addition of the words ``radioactive material'' to a shipping description that does not contain those words. By revising paragraph (d)(1) RSPA is reinstating that requirement. Section 172.310. Section 172.310 is revised by adding the word ``Each'' to the beginning of paragraph (b). Section 172.403. Section 172.403 is revised to correct typographical errors in the label table and to clarify that the allowance to identify radionuclides in terms of curies only applies in domestic transportation. Section 172.803. In Sec. 172.803, RSPA is clarifying that a person, determining if he or she is subject to the radiation protection program based on the total transport index (TI) handled, can exclude the TI from fissile packages that is calculated for criticality control purposes. RSPA received a petition for reconsideration on Sec. 172.803, which stated that RSPA should not limit the category of people who are permitted to make the evaluation described in Sec. 172.803(d)(1)(ii) to only certified health physicists or persons who are recommended by the appropriate Nuclear Regulatory Commission (NRC) or state official. RSPA requires that the evaluator be ``a person experienced with radiation protection programs and transportation regulations and programs.'' Under Sec. 172.803(d)(1)(ii), a person's competency to make the determination described in Sec. 172.803(d)(1)(i) may be evidenced by his or her status as a certified health physicist or by a letter of recommendation from a State Radiation Official. There is no requirement for evidence of the evaluator's competency. Therefore, the petition for reconsideration is denied. In addition, in Sec. 172.803(d)(1)(ii), RSPA is removing the reference to the NRC because the NRC recently advised RSPA that it will not provide letters of recommendation. Appendix B to Part 172. Appendix B to Part 172 was added in the final rule to specify the size of the trefoil symbol for package markings, labels and placards. However, several persons advised RSPA that the new trefoi#
Passage 4l size makes it very difficult to produce the RADIOACTIVE placard and label in the design specified in the HMR. These persons requested that labels and placards that were printed to the old trefoil specifications continue to be allowed for an unlimited amount of time. Upon further review of the amendment that adopted the new trefoil size for placards and labels, RSPA believes that the new size requirements impose unnecessary costs. Therefore, RSPA is revising Appendix B to Part 172 to require that the inner circle of the trefoil symbol on a radioactive label have a radius of at least 4 millimeters and that the outer circle of the trefoil symbol on a radioactive placard have a radius of at least 56.25 millimeters. In addition, RSPA is allowing the continued use of those labels and placards that were printed prior to April 1, 1996, in accordance with the regulations in effect on March 30, 1996. Section 173.411. For consistency with other sections of the HMR, RSPA is removing the phrase ``greater than 20% increase'' from Sec. 173.411(b)(2)(ii) and replacing it with the phrase ``significant increase''. This change will make the requirements for Type 2 and 3 Industrial Packages consistent with the requirements for a Type A package. Section 173.417. In Sec. 173.417, Table 3 is reprinted in the correct format, and paragraph (b)(2) is revised to reflect the appropriate restrictions for the Specification 6M packaging, based upon assigned criticality transport indices (TI). Clarifications are being made to show that paragraph (b)(2)(i) applies to materials with criticality TI's equal to zero and that paragraph (b)(2)(ii) and footnote 7 apply to materials with criticality TI's greater than zero. Section 173.422. Section 173.422 is revised to correctly note that persons who ship limited quantities of Class 7 materials must comply with the training requirements of Part 172, and that limited quantities of a Class 7 material that is a hazardous substance or a hazardous waste must comply with the shipping paper requirements of the HMR. In addition, RSPA is providing an exception from the certification requirements of Sec. 173.422(a) for limited quantities of Class 7 materials that are subject to the shipping paper requirements of the HMR. Section 173.425. Editorial errors in the table of activity limits for limited quantities in Table 7 are corrected and footnote 2, regardi#
Passage 5ng luminous paint, is added back to the table. Section 172.426. Section 173.426 is revised to correct section references. Section 173.427. In Sec. 173.427, paragraph (a)(3) is revised by adding a reference to ``Sec. 173.467'' to make it clear that fissile packages must comply with the provisions of Sec. 173.467. In addition, in paragraph (c)(1), RSPA is removing the phrase ``in a closed transport vehicle'' from the requirements for shipping bulk packages of low specific activity material and surface contaminated objects. In addition, RSPA is adding references to the NRC-approved packagings to make it clear that these are authorized packagings for the shipment of low specific activity material and surface contaminated objects. Section 173.428. Section 173.428 is revised to correct section references and a misspelled word. Section 173.435. Several editorial corrections are made to the Table of A1 and A2 values in Sec. 173.435. In addition, the entry ``MFP'', which stands for mixed fission products, is added back to the table. Section 173.443. Section 173.443 is revised by correcting editorial errors in Table 11. Section 173.465. Section 173.465 is revised to correct a misspelled word and to correct unit conversions. Section 174.700. Section 174.700 is revised to correct a section reference and by correcting the limit in paragraph (b) so that it applies to each rail car and not to the entire train. Section 176.700. Section 176.700 is revised to correct the reference to the required marking requirements for low specific activity radioactive material. 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 was not reviewed 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). The original regulatory evaluation was reexamined but was not modified because changes made under this rule do not change the analysis in that evaluation.#
Passage 6This final rule has been analyzed in accordance with the principles and criteria contained in Executive Order 12612 (``Federalism''). The Federal hazardous materials transportation law (49 U.S.C. 5101-5127) contains an express preemption provision that preempts State, local, and Indian tribe requirements on certain covered subjects. 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 final rule concerns the packaging and classification of radioactive materials. This final rule preempts State, local, or Indian tribe requirements in accordance with the standards set forth above. The Federal statute 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 (49 USC 5125(b)(2)). 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 these requirements is August 2, 1996. Thus RSPA lacks discretion in this area, and preparation of a federalism assessment is not warranted. Any interested person may petition RSPA's Administrator for reconsideration of this final rule within 30 days of publication of this rule in the Federal Register, in accordance with the procedures set forth at 49 CFR 106.35. Neither the filing of a petition for reconsideration nor any other administrative proceeding is required before the filing of a suit in court for review of this rule.#
Passage 7I certify that this final rule will not have a significant economic impact on a substantial number of small entities. This rule applies to shippers and carriers of radioactive materials, some of whom are small entities. 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.

Passage 11* * * * * (b) * * * (2) DOT Specification 6M (Sec. 178.354 of this subchapter), metal packaging. These packages must contain only solid Class 7 (radioactive) materials that will not decompose at temperatures up to 121 deg.C (250 deg.F). Radioactive decay heat output may not exceed 10 watts. Class 7 (radioactive) materials in other than special form must be packaged in one or more tightly sealed metal cans or polyethylene bottles within a DOT Specification 2R (Sec. 178.360 of this subchapter) containment vessel. (i) For fissile material with a criticality TI equal to 0.0, packages are limited to the following amounts of fissile Class 7 (radioactive) materials: 1.6 kilograms of uranium-235; 0.9 kilograms of plutonium (except that due to the 10-watt thermal decay heat limitation, the limit for plutonium-238 is 0.02 kilograms); and 0.5 kilograms of uranium-233. The maximum ratio of hydrogen to fissile material may not exceed three, including all of the sources of hydrogen within the DOT Specification 2R containment vessel. (ii) Maximum quantities of fissile material and other restrictions for materials with a criticality TI of greater than 0.0 are given in Table 5. The minimum transport index to be assigned per package and, for fissile material, controlled shipments, the allowable number of similar packages per conveyance and per transport vehicle are shown in Table 5. Where a maximum ratio of hydrogen to fissile material is specified in Table 5, only the hydrogen interspersed with the fissile material must be considered. For a uranium-233 shipment, the maximum inside diameter of the inner containment vessel may not exceed 12.1 centimeters (4.75 inches). Where necessary, a tight-fitting steel insert must be used to reduce a larger diameter inner containment vessel specified in Sec. 178.354 of this subchapter to the 12.1 centimeter (4.75 inch) limit.
