SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking

    This direct final rule is published under authority of the Federal 
Hazardous Materials Transportation Law under 49 U.S.C. 5101 et seq. 
Section 5103(b) of Federal Hazmat Law authorizes the Secretary of 
Transportation to prescribe regulations for the safe transportation, 
including security, of hazardous materials in intrastate, interstate, 
and foreign commerce. The National Technology Transfer and Advancement 
Act of 1995 mandates that all federal agencies use technical standards 
developed and adopted by voluntary consensus standards bodies. The 
guidelines used by agencies to assess and report their conformity with 
the requirements of the Act are detailed in Office of Budget and 
Management (OMB) Circular No. A-119, entitled ``Federal Participation 
in the Development and Use of Voluntary Consensus Standards and in 
Conformity Assessment Activities.'' OMB Circular No. A-119 recognizes 
that the vibrancy and effectiveness of the U.S. standards system in 
enabling innovation depends on continued private sector leadership and 
engagement.
    This rulemaking is a Direct Final Rule under PHMSA's rulemaking 
authority outlined in 49 CFR 106.40 to incorporate by reference the 
latest edition of a technical/industry standard. PHMSA has determined 
that this direct final rule is not a ``significant regulatory action'' 
as defined in section 3(f) of Executive Order 12866, and is not 
``significant'' as defined in DOT's Regulatory Policies and Procedures. 
This rulemaking is exempt from the Office of Management and Budget 
review in accordance with Executive Order 12866.

The Direct Final Rule Procedure

    PHMSA is issuing this direct final rule without prior notice and 
prior public comment. The Administrative Procedure Act provides that an 
agency may publish a final rule without prior notice and comment if the 
agency for good cause finds that the notice and comment procedure is 
unnecessary (49 U.S.C. 553(b)(B)). This rule will not make any 
significant substantive changes to the Hazardous Materials Regulations. 
Accordingly, PHMSA does not foresee adverse comments in response to 
this rulemaking, and consequently a 30-day notice and comment period is 
reasonable.
    The Regulatory Policies and Procedures of the Department of 
Transportation (DOT), 44 FR 1134, February 26, 1979, provide that to 
the maximum extent possible, operating administrations for the DOT 
should provide an opportunity for public comment on regulations issued 
without prior notice. Accordingly, PHMSA invites interested persons to 
participate in this rulemaking by submitting written comments. The 
agency also invites comments relating to the economic, environmental, 
energy, or federalism impacts that might result from adopting this 
final rule.
    This direct final rule will take effect as indicated above unless 
PHMSA receives an adverse comment or notice of intent to file an 
adverse comment within the comment period. An adverse comment explains 
why a rule would be inappropriate or would be ineffective or 
unacceptable without a change. It may challenge the rule's underlying 
premise or approach. Under the direct final rule process, we do not 
consider the following types of comments to be adverse:
    (1) A comment recommending another rule change, in addition to the 
change in the direct final rule at issue, unless the commenter states 
why the direct final rule would be ineffective without the change.
    (2) A frivolous or irrelevant comment.
    If we receive an adverse comment or notice of intent to file an 
adverse comment, we will advise the public by publishing a document in 
the Federal Register before the effective date of the final rule. This 
document may withdraw the direct final rule in whole or in part.

[[Page 25615]]

If we withdraw the direct final rule because of an adverse comment, we 
may incorporate the adverse comment into another direct final rule or 
may publish a notice of proposed rulemaking.
    See the ``Additional Information'' section for information on how 
to comment on this direct final rule and how PHMSA will handle comments 
received. The ``Additional Information'' section also contains related 
information about the docket, privacy, and the handling of proprietary 
or confidential business information. There is also information on 
obtaining copies of related rulemaking documents.

I. Background

    This direct final rule adopts the most recent edition of a 
consensus technical standard, the American Society of Mechanical 
Engineers (ASME) Boiler and Pressure Vessel Code (2015 Edition) and 
ASME Code for Transportation Systems for Liquids and Slurries: Pressure 
Piping, B31.4-2012. The Boiler and Pressure Vessel Code enables nurse 
tank manufacturers and other DOT and UN specification packaging 
manufacturers to use current technology, materials, and practices. The 
incorporation of the most recent edition of the ASME Code improves 
clarity, consistency, accuracy, reduces unnecessary burdens on the 
regulated community, and will provide, at minimum, an equivalent level 
of safety for non-specification (nurse tanks) and specification tanks 
regulated under the Hazardous Materials Regulations (HMR). PHMSA is 
replacing the 1998 Edition of ASME Boiler and Pressure Vessel Code 
Sections with the following, current 2015 Edition of ASME Boiler and 
Pressure Vessel Code Sections:

 Section II--Materials--Part A--Ferrous Materials 
Specifications
 Section II--Materials--Part B--Nonferrous Material 
Specifications
 Section V--Nondestructive Examination
 Section VIII--Rules for Construction of Pressure Vessels 
Division 1
 Section IX--Welding, Brazing, and Fusing Qualifications

    PHMSA is also replacing the 1998 Edition of ASME B31.4-1998 
Edition, Pipeline Transportation Systems for Liquid Hydrocarbons and 
other Liquids with the following, current 2012 Edition of ASME B31.4-
2012, now titled Pipeline Transportation Systems for Liquids and 
Slurries as it relates to 49 CFR 173.5a ``Oilfield service vehicles, 
mechanical displacement meter provers, and roadway striping vehicles 
exceptions.''
    For full access to these Sections, please see http://go.asme.org/PHMSA-ASME. PHMSA is aware that industry is already manufacturing nurse 
tanks and other specification cargo tanks in accordance with various 
ASME Editions between 1998 and 2015, and PHMSA is not aware of any 
adverse safety issues, as long as tanks have been properly built in 
accordance with ASME Editions. PHMSA recognizes the safety and validity 
of these ASME Editions published after the 1998 Edition as related to 
this rulemaking. This update will increase PHMSA's ability to ensure 
compliance with the 2015 ASME Edition related to non-specification 
(nurse tanks) and specification cargo tanks and with the 2012 ASME 
edition related to mechanical displacement meter provers.
Standards Incorporated by Reference
    The National Technology Transfer and Advancement Act of 1995 (Pub. 
L. 104-113) directs Federal agencies to use voluntary consensus 
standards in lieu of government-written standards whenever possible. 
Voluntary consensus standards are standards developed or adopted by 
voluntary bodies that develop, establish, or coordinate technical 
standards using agreed upon procedures.
    PHMSA's Office of Hazardous Materials Safety adopts 187 voluntary 
consensus standards issued by 27 different technical organizations, and 
the Office participates in numerous national voluntary consensus 
standards committees. PHMSA adopts voluntary consensus standards 
applicable to packaging design, construction, maintenance, inspection, 
and repair when they are consistent with the safe transportation of 
hazardous materials. PHMSA reviews and approves for incorporation by 
reference updated versions based on this directive. When PHMSA believes 
some aspect of a standard does not meet an adequate level of safety, it 
will not incorporate the standard or the part of the standard that it 
believes is contradictory with the directive.
    Parts 171 through 180 incorporate by reference all or parts of 
standards and specifications developed and published by technical 
organizations, as referenced in 49 CFR 171.7, including, but not 
limited to, the American Petroleum Institute, American Society of 
Mechanical Engineers, American Society for Testing and Materials, 
Compressed Gas Association, International Organization for 
Standardization, Organization for Economic Cooperation and Development, 
and the United Nations. These organizations update and revise their 
published standards periodically to reflect modern technology and best 
technical practices. PHMSA has reviewed the revised voluntary consensus 
standards being incorporated in this final rule.
New Edition of Standards
2015 Edition of the American Society of Mechanical Engineers Boiler and 
Pressure Vessel Code
 Section II--Materials--Part A--Ferrous Materials 
Specifications
 Section II--Materials--Part B--Nonferrous Material 
Specifications

    Parts A and B of Section II are ``Service Sections'' to the other 
Sections of the Boiler and Pressure Vessel Code, and they provide 
material specifications for ferrous and nonferrous materials adequate 
for safety in the field of pressure equipment. These specifications 
contain requirements for chemical and mechanical properties, heat 
treatment, manufacture, heat and product analyses, and methods of 
testing.

 Section V--Nondestructive Examination

    Section V contains requirements and methods for nondestructive 
examination, which are referenced and required by other Sections. It 
also includes manufacturers' examination responsibilities, duties of 
authorized inspectors and requirements for qualification of personnel, 
inspection and examination.

 Section VIII--Rules for Construction of Pressure Vessels, 
Division 1

    Section VIII, Division 1 provides requirements applicable to the 
design, fabrication, inspection, testing, and certification of pressure 
vessels operation at either internal or external pressures exceeding 15 
psig. Division 1 also contains mandatory and non-mandatory appendices 
detailing supplementary design criteria, nondestructive examination and 
inspection acceptance standards.

 Section IX--Welding, Brazing, and Fusing Qualifications

    Section IX contains rules relating to the qualification of welding, 
brazing, and fusing procedures as required by other Sections for 
component manufacture. It also covers rules relating to the 
qualification and requalification of welders, brazers, and welding, 
brazing and fusing machine operators in order that they may perform 
welding, brazing, or plastic fusing as required by other Sections in 
the manufacture of components.
    The above editions of currently referenced standards are being

[[Page 25616]]

incorporated by reference in 49 CFR 171.7, 173.315, and 178.338-3. 
These new Editions refine and clarify existing material in the standard 
and generally do not introduce new topics.
2012 Edition of the American Society of Mechanical Engineers Pipeline 
Transportation Systems for Liquids and Slurries, ASME B31.4-2012
 This Edition covers piping and transporting liquids between 
production facilities, tank farms, natural gas processing plants, 
refineries, pump stations, ammonia plants, terminals (marine, rail, and 
truck), and other delivery and receiving points.
    The above standard is being incorporated by reference in 49 CFR 
173.5a. This Edition refines and clarifies existing material in the 
standard and generally does not introduce new topics as related to 
mechanical displacement meter provers. PHMSA is not seeking or 
accepting comments on the unrelated, Proposed Rule entitled ``Hazardous 
Materials: Adoption of ASME Code Section XII and the National Board 
Inspection Code'' (docket number PHMSA-2010-0019; RIN 2137-AE58). This 
rulemaking also has no impact on or relation to the Pipeline Safety 
Regulations at 49 Code of Federal Regulations Part 190-199.
Incorporation By Reference Discussion Under 1 CFR Part 51
    The 2015 Edition of the American Society of Mechanical Engineers 
Boiler and Pressure Vessel Code and the 2012 Edition of the American 
Society of Mechanical Engineers Pipeline Transportation Systems for 
Liquids and Slurries are freely accessible to the public for the full 
30 day comment period online at http://go.asme.org/PHMSA-ASME. In 
addition, all Sections of the 2015 Edition of the Boiler and Pressure 
Vessel Code are available for purchase directly from ASME online at 
https://www.asme.org/shop/standards#des=BPVC and the 2012 Edition of 
the American Society of Mechanical Engineers Pipeline Transportation 
Systems for Liquids and Slurries is available for purchase directly 
from ASME online at https://www.asme.org/products/codes-standards/b314-2012-pipeline-transportation-systems-liquid. Members of the public may 
access hard copies of standards incorporated by reference at PHMSA's 
Hazardous Materials Information Center (HMIC) at the Department of 
Transportation Headquarters in Washington, DC. Members of the public 
may make arrangements to visit the HMIC by visiting HMIC's Web site at 
http://www.phmsa.dot.gov/hazmat/standards-rulemaking/hmic or by 
telephone at 800-467-4922. PHMSA staff will work directly with any 
person requesting access to these standards.
    PHMSA believes the majority of industry nurse tank manufacturers 
and other DOT and UN specification packaging manufacturers has already 
purchased and therefore possess and adhere to these standards in order 
to be certified under ASME's various certification programs. For 
example, products manufactured by ASME BPVC Certificate Holders are 
certified and stamped with a Certification Mark in accordance with the 
applicable ASME BPVC Section. According to ASME, there are currently 
more than 6,800 Certificate Holders in the ASME BPVC Certification 
Program. For more information on ASME's Certification Programs, please 
see https://www.asme.org/shop/certification-and-accreditation/boiler-and-pressure-vessel-certification.

II. Regulatory Notices and Analyses

A. Regulatory Flexibility Determination and Executive Order 13272
    Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), PHMSA 
is required to consider whether rulemaking actions would have a 
significant economic impact on a substantial number of small entities. 
This direct final rule ensures that manufacturers are able to use the 
most current editions of technical standards incorporated by reference. 
PHMSA concludes this rule does not have a significant negative economic 
impact on any small entity. Based on the facts available about the 
expected impact of this rulemaking, PHMSA certifies under Section 605 
of the Regulatory Flexibility Act (5 U.S.C. 605) that this rulemaking 
will not have a significant economic impact on a substantial number of 
small entities.
B. Paperwork Reduction Act
    There are no new information collection requirements in this direct 
final rule.
C. Unfunded Mandates Assessment
    This direct final rule does not impose unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. It does not result in costs of 
$155,000,000 or more, adjusted for inflation, to either State, local or 
tribal governments, in the aggregate, or to the private sector in any 
one year, and is the least burdensome alternative that achieves the 
objective of the rule.
D. 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.
E. Environmental Analysis
    The National Environmental Policy Act of 1969 (NEPA), as amended 
(42 U.S.C. 4321-4347), requires Federal agencies to consider the 
consequences of major federal actions and to prepare a detailed 
statement on any action that significantly affects the quality of the 
human environment. Since these new standards provide, at minimum, an 
equivalent level of protection to the currently referenced standards, 
it is unlikely that the adoption of these standards will have any 
impact on the environment. We find that there are no significant 
environmental impacts associated with this direct final rule. PHMSA 
invites comments about environmental impacts that could result from 
this direct final rule.

III. Executive Order Determinations

A. Executive Order 13132, Federalism
    PHMSA has analyzed the direct final rule according to Executive 
Order 13132 (64 FR 43255). This direct final rule does not have a 
substantial direct effect 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. The direct 
final rule does not impose substantial direct compliance costs on State 
and local governments. Therefore, the consultation and funding 
requirements of Executive Order 13132 do not apply.
B. Executive Orders 13563 and 12866 and DOT Policies and Procedures
    This direct final rule is not a significant regulatory action under 
section 3(f) of Executive Order 12866 (58 FR 51735) and, therefore, was 
not subject to review by the Office of Management and Budget. This 
direct final rule is not significant under the Regulatory Policies and 
Procedures of the Department of Transportation (44 FR 11034).
    In this direct final rule we are updating references to standards 
that are incorporated in the Hazardous Materials Regulations. These 
updates will enhance safety while reducing the compliance burden on the 
regulated

[[Page 25617]]

industry. PHMSA welcomes public comments on potential costs and 
benefits of this regulatory action.
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 the direct 
final rule does not significantly or uniquely affect the communities of 
the Indian tribal governments or impose substantial direct compliance 
costs, the funding and consultation requirements of Executive Order 
13175 do not apply.

6. In Sec.  178.338-3, paragraph (a) is revised to read as follows:


Sec.  178.338-3  Structural integrity.

    (a) General requirements and acceptance criteria. (1) Except as 
permitted in paragraph (d) of this section, the maximum calculated 
design stress at any point in the tank may not exceed the lesser of the 
maximum allowable stress value prescribed in Section VIII of the ASME 
Code (IBR, see Sec.  171.7 of this subchapter), or 25 percent of the 
tensile strength of the material used.
    (2) The relevant physical properties of the materials used in each 
tank may be established either by a certified test report from the 
material manufacturer or by testing in conformance with a recognized 
national standard. In either case, the ultimate tensile strength of the 
material used in the design may not exceed 120 percent of the minimum 
ultimate tensile strength specified in either the ASME Code or the ASTM 
standard to which the material is manufactured.
    (3) The maximum design stress at any point in the tank must be 
calculated separately for the loading conditions described in 
paragraphs (b), (c), and (d) of this section. Alternate test or 
analytical methods, or a combination thereof, may be used in lieu of 
the procedures described in paragraphs (b), (c), and (d) of this 
section, if the methods are accurate and verifiable.
    (4) Corrosion allowance material may not be included to satisfy any 
of the design calculation requirements of this section.
