RIN 2137-AD83
Hazardous Materials: Matter Incorporated by Reference
AGENCY: Research and Special Programs Administration (RSPA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This final rule amends the Hazardous Materials Regulations
(HMR) to standardize the format used to cross-reference consensus
standards published by nationally and internationally recognized
standard-setting organizations and industry that are incorporated by
reference into the HMR. In addition, this rule adds missing cross-
references and removes unnecessary cross-references in the HMR. The
amendments contained in this rule are minor editorial changes and
impose no new requirements.
DATES: Effective date: January 1, 2004.
Incorporation by Reference Date: The incorporation by reference of
the publications listed in this final rule has been approved by the
Director of the Federal Register as of January 1, 2004.
FOR FURTHER INFORMATION CONTACT: Eileen Edmonson, 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. Background
The Research and Special Programs Administration (RSPA, we, us)
references certain consensus standards, specifications, and recommended
practices developed by nationally and internationally recognized
standard-setting organizations and the hazardous materials industry to
establish certain requirements in the Hazardous Materials Regulations
(HMR; 49 CFR Parts 171-180). This practice, known as incorporation by
reference, allows us to incorporate the provisions of widely accepted
technical standards into the regulations and to reduce the volume of
material published in the Federal Register. The legal effect of
incorporation by reference is that the referenced provisions are
treated as if they were published in the Federal Register and in the
HMR. As with any other requirements appearing in regulations, the
incorporated provisions have the force and effect of law.
The Office of the Federal Register's (OFR's) regulations, at 1 CFR
Part 51, govern how RSPA and other Federal agencies may incorporate
various documents by reference. These regulations require agencies to
obtain approval from the Director of the Federal Register for each
publication incorporated by reference. Incorporation by reference of a
publication is limited to the specific edition approved by the OFR. In
the HMR, Sec. 171.7 contains a complete listing of the source and name
of each publication approved by the OFR regulations.
The OFR requires an agency to use the words ``incorporated by
reference'' in the language incorporating a publication. The HMR
incorporate by reference more than 100 publications and contain
hundreds of references to these publications. For conciseness, we are
using the wording ``IBR, see Sec. 171.7 of this subchapter'' in the
language incorporating a publication. This wording appears the first
time a publication is referenced in a particular section. Some sections
in the HMR currently contain multiple references to the same
publication. These repeated references when they appear in the same
section are being removed in this final rule.
In an earlier final rule (RSPA Docket No. 02-13658 (HM-215E), 68 FR
1013, January 8, 2003), we revised Sec. 171.7 to incorporate by
reference the 2002 edition of International Maritime Dangerous Goods
Code (IMDG Code), including Amendment 31. We also authorized the
continued use of the 2000 edition of the IMDG Code, including Amendment
30, until January 1, 2004. We are removing the reference to the 2000
edition of the IMDG Code in this final rule.
The rule also contains minor editorial corrections (e.g.,
incomplete section references, and typographical and punctuation
errors), and certain other minor adjustments to enhance the clarity of
the HMR.
Because these amendments impose no new requirements, notice and
public comment procedures are unnecessary. In addition, making these
amendments effective without the customary 30-day delay following
publication will allow the changes to appear in the next revision of 49
CFR.
II. 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 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 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
editorial changes that 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 75735]]
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.

Sec. 171.8 Definitions and abbreviations.
* * * * *
Competent Authority means a national agency responsible under its
national law for the control or regulation of a particular aspect of
the transportation of hazardous materials (dangerous goods). The term
Appropriate Authority, as used in the ICAO Technical Instructions (IBR,
see Sec. 171.7), has the same meaning as Competent Authority. For
purposes of this subchapter, the Associate Administrator is the
Competent Authority for the United States.
* * * * *
Incorporated by reference or IBR means a publication or a portion
of a publication that is made a part of the regulations of this
subchapter. See Sec. 171.7.
* * * * *
Liquid means a material, other than an elevated temperature
material, with a melting point or initial melting point of 20 [deg]C
(68 [deg]F) or lower at a standard pressure of 101.3 kPa (14.7 psia). A
viscous material for which a specific melting point cannot be
determined must be subjected to the procedures specified in ASTM D 4359
``Standard Test Method for Determining Whether a Material is Liquid or
Solid'' (IBR, see Sec. 171.7).
Liquid phase means a material that meets the definition of liquid
when evaluated at the higher of the temperature at which it is offered
for transportation or at which it is transported, not at the 37.8
[deg]C (100 [deg]F) temperature specified in ASTM D 4359 (IBR, see
Sec. 171.7).
* * * * *
NPT means an American Standard taper pipe thread conforming to the
requirements of NBS Handbook H-28 (IBR, see Sec. 171.7).
* * * * *
