Hazardous Materials Regulations; Editorial Corrections and 
Clarifications

AGENCY: Research and Special Programs Administration (RSPA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This final rule corrects editorial errors, makes minor 
regulatory changes, and in response to requests for clarification, 
improves the clarity of certain provisions in the Hazardous Materials 
Regulations (HMR). The intended effect of this rule is to enhance the 
accuracy and reduce misunderstandings of the HMR. This non-substantive 
final rule correcting minor errors in the hazardous materials 
regulations was not preceded by a notice of proposed rulemaking because 
RSPA finds that notice and public comment are unnecessary under the 
Administrative Procedure Act.

EFFECTIVE DATE: October 1, 1998.

FOR FURTHER INFORMATION CONTACT: Charles E. Betts, 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:

Background

    RSPA annually reviews the Hazardous Materials Regulations (HMR) to 
identify errors which may confuse readers. Inaccuracies corrected in 
this final rule include typographical errors, incorrect references to 
other rules and regulations in the CFR, inconsistent use of 
terminology, and misstatements of certain regulatory requirements. In 
response to inquiries RSPA received concerning the clarity of 
particular requirements specified in the HMR, certain other changes are 
made to reduce uncertainties.
    Because these amendments do not impose new requirements, notice and 
public procedure 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.
    The following is a section-by-section summary of the amendments 
made under this final rule. It does not discuss minor editorial 
corrections (e.g., typographical, capitalization and punctuation 
errors), changes to legal authority citations and certain other minor 
adjustments to enhance the clarity of the HMR.

Section-by-Section Review

Part 107

Section 107.503

    Paragraph (a)(3) is revised to remove an obsolete section 
reference.

Section 107.606

    Paragraph (a)(5) is revised to update a 49 CFR part reference. In 
1976, 49 CFR part 1057 was redesignated as part 376. That change was 
never corrected in the registration requirements at Sec. 107.606(a)(5).

Part 171

Section 171.7

    In paragraph (a)(3), in the table of material incorporated by 
reference, in the entry ``IME Safety Library Publication No. 22'', in 
the second column, a reference to ``173.63'' is added immediately 
before ``177.835''.

Section 171.8

    A minor editorial change is made to the ``Marine pollutant'' 
definition to enhance its clarity.
    In the ``Reportable Quantity'' definition, a reference to ``column 
3'' is corrected to read ``column 2''.

Section 171.14

    Paragraph (c) (1) is revised to clarify that the authorization 
allowing a fiber drum with a removable head to be used for a liquid 
hazardous material in Packing Group III that is not poisonous by 
inhalation expired on September 30, 1997.

Part 172

Section 172.101

    In paragraph (c)(11), a reference to ``Sec. 173.51'' is corrected 
to read ``Sec. 173.54''.
    In paragraph (f), in the first sentence, the word ``ORD-D'' is 
removed and the word ``ORM-D'' is added in its place.
    The Hazardous Materials Table (the Table). The Table is amended to 
read as follows:
    The entry ``Anhydrous ammonia see Ammonia, anhydrous, liquefied'' 
is corrected by removing the word ``,liquefied''. Separate entries for 
``Ammonia, anhydrous'' and ``ammonia solutions'' were created under 
Docket HM-215B [62 FR 24707; May 6, 1997].
    In the following proper shipping names, the word ``gases'' is 
revised to read ``gas'', for consistency with the way they are shown in 
the UN Recommendations:
    Compressed gases, flammable, n.o.s.;
    Compressed gases, n.o.s.;
    Compressed gases, toxic, flammable, n.o.s. Inhalation hazard Zone 
A;
    Compressed gases, toxic, flammable, n.o.s. Inhalation hazard Zone 
B;
    Compressed gases, toxic, flammable, n.o.s. Inhalation hazard Zone 
C;
    Compressed gases, toxic, flammable, n.o.s. Inhalation hazard Zone 
D;
    Compressed gases, toxic, n.o.s. Inhalation Hazard Zone A;
    Compressed gases, toxic, n.o.s. Inhalation Hazard Zone B;
    Compressed gases, toxic, n.o.s. Inhalation Hazard Zone C;
    Compressed gases, toxic, n.o.s. Inhalation Hazard Zone D.
    The entry ``Diphenylmethane-4,4' diisocyanate'' is removed. This 
material does not meet the toxicity criteria for a Division 6.1 Packing 
Group III material, and this entry was also deleted from the List of 
Dangerous Goods in the ninth revised edition of the UN Recommendations.
    The entry ``Dichlorodifluoromethane or Refrigerant gas R 122'' is 
corrected by removing ``122'' and replacing it with ``12''.
    For the entry ``Methyl isocyanate, 6.1,UN2480'', Column (7) is 
corrected by removing Special Provision ``A7''. This material is 
forbidden for transportation by aircraft.
    For the entry ``Sodium hydrogendifluoride, solid'', the word 
``solid'' is italicized.
    For the entry ``Sodium hydrogendifluoride, liquid'', the word 
``liquid'' is italicized.
    For the entry ``Uranium hexafluoride, fissile excepted or non-
fissile, 7, UN2978'', columns 8B and 8C are corrected by removing the 
reference ``425'' and replacing it with ``427''.
    For the entry ``Water-reactive, solid, oxidizing, n.o.s., 4.3, 
UN3133'', in column 5, packing group ``II'' is added, in column (10A) 
``E'' is added, and in column (10B), ``40'' is added. In addition, a 
new entry for the material in packing group III is added.

Section 172.102

    In paragraph (c) (1), special Provision 114B is corrected by 
removing the wording ``US006'' and replacing it with ``US1''.

Section 172.203

    Paragraph (m)(1) is revised by removing the wording ``Poison or 
Toxic'' and replacing it with `` `Poison' or `Toxic' ''.

[[Page 52845]]

Section 172.400a

    In paragraph (a)(7), the reference ``Sec. 173.425(b)'' is corrected 
to read ``Sec. 173.427(a)(6)(vi)''.

Section 172.504

    Footnote 1 of Table 1 is revised to correct a section reference.

Part 173

Section 173.6

    In paragraph (c)(2), as amended by 63 FR 8142 the last sentence 
stating ``Each digit in the identification number marking must be 
displayed in 100 mm (3.9 inches) black Helvetica Medium, Alpine Gothic 
or Alternate Gothic No. 3 numerals.'' is removed. The size used for the 
identification number marking is prescribed in Sec. 172.332, depending 
on whether the identification number is placed on a placard, white 
square-on-point configuration, or an orange panel.

Section 173.33

    Paragraph (a)(3) is revised to correct a section reference.

Section 173.34

    In paragraph (e)(18)(i), in the table for DOT 8 or 8AL cylinders 
used to transport acetylene, under ``Porous filler requalification'', 
the entry ``3 to 30 yrs\2\'' is corrected to read ``3 to 20 yrs\2\'' to 
correct a printing error. The ``3 to 20 yrs'' interval is correctly 
shown in the referenced Note 2.

Section 173.58

    Paragraph (a) is amended to correct the title of the referenced 
document from ``Explosive Test Manual,'' to read ``UN Manual of Tests 
and Criteria,''. The ``Explosive Test Manual'' was the title of an 
earlier edition of this document.

Section 173.62

    In paragraph (c), the Table of Packing Methods is revised to 
correct a printing error.

Section 173.247

    On June 5, 1996, RSPA issued Docket HM-216 that added the DOT 120 
tank car specification to Secs. 173.240, 241, 242, 243, 244, and 314 
but failed to add the ``120'' specification to Sec. 173.247 (a). This 
oversight is corrected.

Section 173.403

    A printing error is corrected in the definition of ``LSA--II''.

Section 173.416

    A minor editorial change is made in paragraph (f) for clarity.

Section 173.422

    Paragraph (b)(1) is revised to correct section references.

Section 173.425

    Section 173.421 defines a limited quantity of Class 7 (radioactive) 
material as having an activity per package value not exceeding the 
limits specified in Sec. 173.425. In Table 7 of Sec. 173.425, the 
limited quantity values are not specifically identified, which leads to 
confusion. To eliminate this confusion, the column heading ``Materials 
package limits\1\'' is revised to read ``Limited quantity package 
limits\1\''.

Section 173.427

    Paragraph (a)(3) is revised to replace reference to obsolete 
Sec. 173.451 with references to Secs. 173.453, 173.457, 173.459 and 
173.467. This change does not impose any new requirement.

Section 173.433

    In paragraph (g), in ``Table 10.--General Values For A1 
and A2'', in the first column, the second sentence is 
amended by adding the wording ``no'' immediately before ``relevant'' to 
enhance its clarity.

Section 173.461

    Paragraph (a) is revised to remove reference to obsolete, 
Sec. 173.463 and to include a reference to the design requirements in 
Sec. 173.412 for clarity. These changes do not impose any new 
requirement. Also paragraph (b) is revised to remove a reference to 
obsolete Sec. 173.463.

Part 175

Section 175.700

    In Sec. 175.700, in paragraph (b), in the first sentence, the 
reference ``Sec. 175.15'' is corrected to read ``Sec. 171.15''.

Part 176

Section 176.704

    Paragraph (e)(1) is revised to remove a reference to obsolete 
Sec. 176.451.
    In paragraph (f), in ``Table III--Limits for Freight Containers and 
Conveyances'', the table heading is amended by adding the wording 
``TI'' immediately before ``Limits'' to enhance clarity.

Part 177

Section 177.835

    Paragraph (g), in the second sentence, is corrected by removing a 
comma between the words ``detonating cord'' and ``Division 1.4''. This 
change is made to clarify that the detonating cord is classed in 
Division 1.4.

Section 177.842

    In the first sentence of paragraph (a), the wording ``or storage 
location'' is revised to read ``or in any single group in any storage 
location,''. Paragraph (a) currently reads: ``The number of packages of 
Class 7 (radioactive) materials in any transport vehicle or storage 
location must be limited so that the total transport index number does 
not exceed 50''. The revision to paragraph (a) is made to clarify that 
groups of up to 50 TI are allowed in storage if each group is separated 
by at least 6 meters (20 feet). This revision is consistent with the 
wording in current paragraph (b)(2).

Section 177.843

    Paragraph (c) is revised to correct a section reference.

Section 177.854

    The introductory text preceding paragraph (a) is unnecessary and 
therefore is removed.

Part 178

Section 178.338

    The section heading is amended by adding the wording ``motor 
vehicle'' immediately following the word ``tank'' to enhance clarity.

Part 179

Part 179--Specifications for Tank Cars

    The Table of Sections to Part 179 is amended by revising the 
heading for Subpart C to read as follows: ``Subpart C--Specifications 
for Pressure Tank Car Tanks (Classes DOT-105, 109, 112, 114, and 
120)''. On June 5, 1996 (61 FR 28666, 28679), RSPA amended 
Sec. 179.101-1 by adding the DOT 120 specification to the table. 
However, the title to Subpart C of Part 179 was not changed to reflect 
addition of the new DOT 120 tank car.

Section 179.2

    Paragraph (a)(2) is updated to reflect a minor name change of an 
organizational committee within the Association of American Railroads.

Section 179.3

    Paragraph (a) is updated to reflect a minor name change of an 
organizational committee within the Association of American Railroads.

Section 179.4

    Paragraphs (a) and (b) are updated to reflect a minor name change 
of an organizational committee within the Association of American 
Railroads.

[[Page 52846]]

Section 179.5

    Paragraph (a) is updated to reflect a minor name change of an 
organizational committee within the Association of American Railroads, 
and to reflect that the construction and testing of multi-unit tank car 
tanks are approved by RSPA.

Part 180

Section 180.403

    The introductory text, referencing the definitions contained in 
Secs. 171.8 and 178.345-1, is revised to include a reference to the 
definitions of cargo tank terms in Sec. 178.320(a).

Section 180.417

    Paragraph (a)(3)(ii) is revised to clarify that a ``data report'' 
is the cargo tank ``manufacturer's data report'' required by the ASME.

Section 180.509

    Paragraph (c)(3)(ii) is amended to add an explanation of the terms 
used in the preceding formula. This information was inadvertently 
omitted.

Section 180.515

    In paragraph (b), in the first sentence, the word ``pressure'' is 
added immediately after the word ``Converted''. The word pressure was 
unintentionally removed in a final rule (HM-175 A/201 60 FR 49048; 
September 21, 1995).

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, 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 12612

    This final rule has been analyzed in accordance with the principles 
and criteria in Executive Order 12612 (``Federalism''). The Federal 
hazardous material transportation law, (49 U.S.C. 5101-5127) contains 
express preemption provisions at 49 U.S.C. 5125.
    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.

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.
