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 §§ 110.20 and 171.8 to the listing of definitions and abbreviations for uniformity and continuity with the definition that appears in § 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 § 179.2 is removed and is added in §§ 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 § 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 § 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 § 179.2—Definitions and abbreviations, since the entry already is in § 171.8.

—The term “UN Recommendations” is added in § 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 § 172.102, special provision 27 does not appear in any entry in the § 172.101 Hazardous Materials Table and is removed.

—A typographical error is corrected in § 173.315(n)(1)(v), column (4), by replacing “paragraph (n)(3)” with “paragraph (n)(2)” the second time it appears.

—In § 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. Start Printed 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.
