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.
[[Page 20748]]
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.

Transportation, 400 Seventh Street, SW, Washington, DC 20590.
SUPPLEMENTARY INFORMATION:
I. Background
On 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.
II. Section-by-Section Review
Section 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 trefoil 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,
regarding 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.
[[Page 20749]]
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.
III. Regulatory Analyses and Notices
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.
B. Executive Order 12612
This 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.
C. Executive Order 12778
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.
D. Regulatory Flexibility Act
I 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.
E. Paperwork Reduction Act
There are no new information collection requirements in this final
rule.
F. Regulation Identifier Number (RIN)
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.

(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
[[Page 20751]]
inner containment vessel specified in Sec. 178.354 of this subchapter
to the 12.1 centimeter (4.75 inch) limit. Table 5 is as follows:
