SUPPLEMENTARY INFORMATION:
I. Background
The Research and Special Programs Administration (RSPA, we)
annually reviews the Hazardous Materials Regulations (HMR; 49 CFR Parts
171-180) to identify errors that may confuse readers. Inaccuracies
corrected in this final rule include typographical and printing errors,
incorrect references to regulations in the CFR, inconsistent use of
terminology, and misstatements of certain regulatory requirements. In
addition, we are making certain other changes to improve the clarity of
certain HMR requirements.
Because these amendments do not impose new requirements, notice and
public procedure are unnecessary. For this same reason, we are making
these amendments effective without the customary 30-day delay following
publication.
The following is a section-by-section summary of the amendments
made under this final rule. It does not discuss all minor editorial
corrections (for example, typographical and punctuation errors) and
certain other minor adjustments to enhance the clarity of the HMR.
II. Section-by-Section Review
Part 171
Sections 171.15 and 171.16. In Sec. Sec. 171.15(b) and 171.16(b),
we are updating the term ``FAA Civil Aviation Security Office'' to read
``FAA Regional or Field Security Office.''
Part 172
Section 172.101 Hazardous Materials Table (HMT). We are amending
the HMT by correcting certain entries as follows:
--The hazard class for the entry ``Combustible liquid, n.o.s.,''
NA1993, is revised by correcting Column (3) to read ``Combustible
liquid.'' Due to a typographical error, the entry currently reads
``Combustible.''
--For the entry ``Self-reactive liquid type F,'' UN3229, we are
correcting the reference ``114'' to read ``224.''
Section 172.102. We are correcting Special Provision 15 by removing
text that conflicts with the assigned packaging authorization section,
Sec. 173.161, for the entries ``Chemical kits,'' and ``First aid
kits.'' This correction is based on comments from the public stating
that the text is confusing.
Section 172.201. We are revising paragraph (e) to clarify that the
use and retention of a permanent shipping paper for multiple shipments
of one or more hazardous materials being transported on a regular basis
over an extended period is authorized. In the final rule published on
July 12, 2002 (67 FR 46123) under Docket HM-207B, we authorized
operators to retain a single copy of such permanent shipping papers for
the period in which the shipping paper is used and 375 days thereafter,
provided that the operator also retains a record of each shipment made
under the shipping paper. Also, see Sec. 177.817.
Section 172.321. We are editorially revising paragraph (c)(5) by
removing the semi-colon and the word ``and.''
Section 172.332. We are revising paragraph (b)(3) by adding ``0.25
inches'' as the conversion for ``18 points.''
Part 173
Section 173.32. We are editorially revising paragraph (c)(2) for
clarity by changing the word ``it'' to read ``the portable tanks.''
Section 173.134. In paragraph (c)(1)(ii), we are changing the
wording ``the specific packaging requirements of this section'' to read
``the specific packaging requirements of Sec. 173.197.''
Section 173.164. We are removing paragraph (a)(2) because it is
redundant with the introductory paragraph (a).
Section 173.166. As revised in the final rule, HM-215E ( 68 FR
44992), published on July 31, 2003, we are editorially revising
introductory paragraph (e) by adding ``as follows'' to connect the
introductory paragraph to its subparagraphs.
Section 173.197. We are revising paragraph (e)(1)(i) by correcting
two American Society for Testing and Materials Standard numbers.
Section 173.241. In paragraph (c), we are adding a sentence to
refer the reader to the portable tank requirements in Sec. 176.340
applicable to combustible liquids being transported by vessel.
Section 173.304a. In the table in paragraph (d), we are correcting
the entry for hydrogen sulfide, in column 3, to remove an inconsistency
with provisions in Sec. Sec. 173.40(b) and 173.301a(d)(3) that state
the pressure of a gas at 55 [deg]C (131 [deg]F) may not exceed the
cylinder's service pressure. The service pressure of hydrogen sulfide
at 55 [deg]C (131 [deg]F) exceeds the marked service pressure, 480 psi,
specified in the table.
Section 173.315. In paragraph (b)(1), we are correcting the word
``That'' to read ``that'.
Section 173.337. In paragraph (a), we are removing an incorrect
reference to ``3ALM'' cylinders.
Section 173.412. In paragraph (l), we are correcting ``40 TBq
(1000Ci)'' to read ``40 TBq (1080Ci)'' because it is a more precise
conversion of the activity of 40 TBq to curies.
Section 173.420. In paragraph (a)(2)(i), we are removing the
edition dates for American National Standard (ANSI) N 14.1 because they
are indicated in Sec. 171.7.
Part 175
Section 175.31 In paragraph (a), we are updating the term ``FAA
Civil Aviation Security Office'' to read ``FAA Regional or Field
Security Office.''
Part 176
Section 176.340 We are revising paragraph (a) to clarify the type
of authorized portable tanks by adding the word ``Specification.''
Part 177
Section 177.817 We are revising paragraph (f) to clarify that the
use and retention of a permanent shipping paper for multiple shipments
of one or more hazardous materials being transported on a regular basis
over an extended period is authorized. Also, see Sec. 172.201.
Section 177.854. We are revising paragraph (f)(1) by correcting the
spelling of the word ``motor.''
Part 178
Section 178.61. We are revising paragraph (g) to correct the
location in 49 CFR for the heat treatment methods. The methods are
contained in Table 1 of Appendix A to Part 178--Specifications for
Steel. Currently, the paragraph incorrectly cites paragraph (b), which
contains requirements for authorized steel and references Table 1 of
Appendix A for chemical composition limits and makes no reference to
heat treatment.
Section 178.274. We are revising paragraph (b)(1) to clarify that
portable tanks used for Zone A or B toxic-by-inhalation liquids are
required to have an ASME Certification and U Stamp.
[[Page 57631]]
This revision is consistent with Sec. 178.273(b)(6). We are also
correcting the section reference Sec. 178.247(a)(2)'' in paragraph (i)
(1) to read ``Sec. 178.274(a)(2).''
Section 178.337-10. In paragraph (a), we are revising the wording
``safety relief devices'' to read ``pressure relief devices.''
Section 178.337-17. In paragraph (d), we are correcting the section
reference Sec. 178.337(3)(b)'' to read ``Sec. 178.337-3(b).''
Section 178.338-3. In paragraphs (c)(3)(ii), (c)(3)(iii),
(c)(3)(iv), (c)(3)(v), (c)(3)(vi) and (c)(4), we are removing the
wording ``and (c)'' as an incorrect paragraph reference.
Section 178.338-9. In paragraph (c)(2), we are correcting the
section reference Sec. 178.320 (a) (3)'' to read ``Sec. 178.320(a).''
Section 178.338-18. In paragraph (d), we are removing the wording
``and (c)'' as an incorrect reference.
Part 179
Section 179.102-4. We are revising the section heading to correct a
proper shipping name.
Sections 179.300-12 and 179.500-12. In paragraph (b) of each
section, we are revising the wording ``safety relief devices'' to read
``pressure relief devices.''
III. Rulemaking 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, therefore, was not
reviewed by the Office of Management and Budget. This rule is not
significant under the Regulatory Policies and Procedures of the
Department of Transportation (44 FR 11034). Because there in no
economic impact of this rule, preparation of a regulatory impact
analysis is not warranted.
B. Executive Order 13132
This final rule has been analyzed in accordance with the principles
and criteria in Executive Order 13132 (``Federalism''). This final rule
does not adopt any regulation that: (1) Has substantial direct effects
on the States, the relationship between the national government and the
States, or the distribution of power and responsibilities among the
various levels of government; (2) imposes substantial direct compliance
costs on State and local governments; or (3) preempts state law.
RSPA is not aware of any State, local, or Indian tribe requirements
that would be preempted by correcting editorial errors and making minor
regulatory changes. This final rule does not have sufficient federalism
impacts to warrant the preparation of a federalism assessment.
C. Executive Order 13175
This rule has been analyzed in accordance with the principles and
criteria contained in Executive Order 13175 (``Consultation and
Coordination with Indian Tribal Governments''). Because this rule does
not have tribal implications and does not impose substantial direct
compliance costs, the funding and consultation requirements of
Executive Order 13175 do not apply.
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 makes minor
regulatory changes which will not impose any new requirements on
persons subject to the HMR; thus, there are no direct or indirect
adverse economic impacts for small units of government, businesses or
other organizations.
E. Unfunded Mandates Reform Act of 1995
This rule does not impose unfunded mandates under the Unfunded
Mandates Reform Act of 1995. It does not result in costs of $100
million or more to either State, local, or tribal governments, in the
aggregate, or to the private sector, and is the least burdensome
alternative that achieves the objective of the rule.
F. Paperwork Reduction Act
There are no new information collection requirements in this final
rule.
G. 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.
