Hazardous Materials Regulations: Minor Editorial Corrections and
Clarifications
AGENCY: Research and Special Programs Administration (RSPA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This final rule corrects inconsistencies in terminology and
makes minor editorial corrections to improve the clarity of the
Hazardous Materials Regulations (HMR). The intended effect of this rule
is to enhance the accuracy and reduce misunderstandings of the
regulations. The amendments contained in this rule are minor editorial
changes and do not impose new requirements.
DATES: Effective Date: September 27, 2001.
FOR FURTHER INFORMATION CONTACT: Gigi Corbin, Office of Hazardous
Materials Standards, (202) 366-8553, Research and Special Programs
Administration, U.S. Department of Transportation, 400 Seventh Street,
SW., Washington, DC 20590-0001.
SUPPLEMENTARY INFORMATION:
I. Introduction
This final rule corrects inconsistent use of terminology to enhance
the clarity of the HMR. Because these amendments do not impose new
requirements, notice and public comment procedures are unnecessary.
II. Summary of Regulatory Changes
The following is a summary of the amendments made under this final
rule. It does not discuss all minor editorial corrections (for example:
typographical, capitalization and punctuation errors) and certain other
minor adjustments to enhance the clarity of the HMR.
--The term ``Associate Administrator'' is added in Secs. 110.20 and
171.8 to the listing of definitions and abbreviations for uniformity
and continuity with the definition that appears in Sec. 107.3. The
wording ``Associate Administrator for Hazardous Materials Safety'' is
revised to read ``Associate Administrator'' wherever it appears in 49
CFR Parts 107 through 180. However, the title ``Associate Administrator
for Hazardous Materials Safety'' is retained when it appears as part of
an address.
--The definition of ``DOT and Department'' in Sec. 179.2 is removed and
is added in Secs. 107.3 and 171.8. All other references to ``Department
of Transportation'' are revised to read ``Department'', except where
they appear in an address.
--Obsolete references to Explosive A, Class A, Explosive B, Class B,
Explosive C, Class C and blasting agent are removed.
--The term ``frangible disc'' is revised to read ``rupture disc'' for
consistency of usage. These terms are synonymous.
--The definition of ``intermediate bulk container'' in Sec. 171.8 is
revised to include the acronym ``IBC.'' All other references in the HMR
to ``intermediate bulk container'' and ``intermediate bulk containers''
are revised to read ``IBC'' or ``IBCs'' respectively.
--The definition of ``Maximum Allowable Working Pressure or MAWP'' in
Sec. 171.8 is removed and the acronym ``MAWP'' is added. All other
references to ``maximum allowable working pressure'' are revised to
read ``MAWP''.
--RSPA has reviewed the references to units of pressure measurements in
the HMR for consistency. The units used are psi (pounds per square
inch), psig (pounds per square inch, gauge) and psia (pounds per square
inch, absolute). Revisions have been made, where necessary, to
designate ``psi'' for units of material stress, ``psig'' for test
pressure measurements, and ``psia'' for measurements of vapor pressure.
The entry ``Psi'' is removed in Sec. 179.2--Definitions and
abbreviations, since the entry already is in Sec. 171.8.
--The term ``UN Recommendations'' is added in Sec. 171.8 to the listing
of definitions and abbreviations. References to the ``UN
Recommendations on the Transport of Dangerous Goods'' are revised to
read ``UN Recommendations''.
--In Sec. 172.102, special provision 27 does not appear in any entry in
the Sec. 172.101 Hazardous Materials Table and is removed.
--A typographical error is corrected in Sec. 173.315(n)(1)(v), column
(4), by replacing ``paragraph (n)(3)'' with ``paragraph (n)(2)'' the
second time it appears.
--In Sec. 175.78, all references to ``ICAO'' (hazard) classes are
removed.
--Text indicating units of measure is replaced by the International
System of Units (SI) symbol.
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
subject to review by the Office of Management and Budget. This rule is
not significant according to the Regulatory Policies and Procedures of
the Department of Transportation (44 FR 11034). Because of the minimal
economic impact of this rule, preparation of a regulatory impact
analysis or a regulatory evaluation 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 propose 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 13084
This rule has been analyzed in accordance with the principles and
criteria contained in Executive Order 13084 (``Consultation and
Coordination with Indian Tribal Governments''). Because this rule would
not significantly or uniquely affect the communities of the Indian
tribal governments, the funding and consultation requirements of this
Executive Order 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
editorial 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.
[[Page 45377]]
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.
