SUPPLEMENTARY INFORMATION:

I. Background

PHMSA annually reviews the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to identify errors that may confuse readers. Inaccuracies corrected in this final rule include typographical errors; incorrect references to regulations in the CFR; inaccurate office names and internet addresses; inconsistent use of terminology; and misstatements of certain regulatory requirements. In response to inquiries PHMSA received concerning the clarity of certain 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. By making these amendments effective without the customary 30-day delay following publication, the changes will appear in the next revision of 49 CFR.

The following is a summary by section of the changes made in this final rule. It does not discuss all minor editorial corrections (e.g., punctuation errors), and certain other minor adjustments to enhance the clarity of the HMR (e.g., corrections to office names and internet addresses).

II. Section-by-Section Review

III. 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 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). This final rule will not result in increased compliance costs for hazardous materials shippers or carriers; therefore, it is not necessary to prepare a regulatory impact analysis.

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 adopt 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. PHMSA 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 Start Printed Page 54390federalism impacts to warrant the preparation of a federalism assessment.

C. Executive Order 13175

This final 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 final rule does not have tribal implications, does not impose substantial direct compliance costs on Indian tribal governments, and does not preempt tribal law, the funding and consultation requirements of Executive Order 13175 do not apply, and a tribal summary impact statement is not required.

D. Regulatory Flexibility Act, Executive Order 13272, and DOT Procedures and Policies

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 $120.7 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. Environmental Impact Analysis

There are no environmental impacts associated with this final rule.

H. 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.

Each UN pressure receptacle that becomes due for requalification must be requalified at the interval prescribed in paragraph (c) of this section and in accordance with the procedures contained in the following standard, as applicable. When a pressure test is performed on a UN pressure receptacle, the test must be a water jacket volumetric expansion test suitable for the determination of the cylinder expansion or a hydraulic proof pressure test. The test equipment must conform to the accuracy requirements in § 180.205(g). Alternative methods (e.g. acoustic emission) or requalification procedures may be performed if prior approval has been obtained in writing from the Associate Administrator.

(1) Seamless steel: Each seamless steel UN pressure receptacle, including MEGC's pressure receptacles, must be requalified in accordance with ISO 6406 (IBR, see § 171.7 of this subchapter).
