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
