SUPPLEMENTARY INFORMATION:

I. General Discussion

    PHMSA's regulations at 49 CFR part 195 for hazardous liquid and 
carbon dioxide pipelines provide an explicit exception for ``in-plant 
piping systems'' at certain facilities. 49 CFR 195.1(b)(8);

[[Page 28607]]

49 U.S.C. 60101(a)(22)(B)(ii)-(iii). PHMSA's regulations at 49 CFR part 
192 for gas pipelines do not explicitly recognize a similar exception, 
although PHMSA has often applied the same principles in evaluating the 
regulatory status of in-plant piping systems at gas processing, 
manufacturing, and industrial facilities (PI-09-0020 (Aug. 11, 2010); 
PI-15-0002 (Apr. 2, 2015); PI-18-0012 (Apr. 29, 2019); PI-22-0007 (Jul. 
7, 2022)).
    PHMSA has also acknowledged that in-plant piping systems are 
subject to regulation under other Federal or State programs, such as 
the Occupational Safety and Health Administration's Process Safety 
Management regulations in 29 CFR 1910.119, and that these regulatory 
programs can provide a comparable or equivalent level of safety to the 
requirements in parts 192 and 195. PHMSA has further recognized that 
applying overlapping regulatory programs to in-plant piping systems 
often results in uncertainty and duplicative or contradictory 
compliance obligations (85 FR 70124 (Nov. 4, 2020); Docket No. PHMSA-
2019-0199).
    In addition, stakeholders have recently submitted comments 
emphasizing that the absence of explicit exception for in-plant piping 
systems in part 192 imposes undue burdens on owners and operators of 
gas pipeline facilities (90 FR 14593 (Apr. 3, 2025); Docket No. DOT-
OST-2025-0026). They have asked PHMSA to address that issue by 
codifying such an exception consistent with its prior interpretations 
and the comparable provisions in part 195 (DOT-OST-2025-0026-0830 (May 
5, 2025).
    PHMSA agrees with the commenters and is proposing to add an 
exception to Sec.  192.1(b) for in-plant piping systems. PHMSA's 
proposal includes a definition for in-plant piping system that aligns 
with the provisions in part 195, but which establishes a clear point of 
demarcation between in-plant piping systems and transportation-related 
pipelines based on prior interpretations. Specifically, PHMSA is 
proposing to clarify that the point of demarcation for in-plant piping 
is the inlet of the pressure control device if the pipeline is moving 
product away from plant grounds, the outlet of the pressure control 
device if the pipeline is supplying the plant, or, if there is no such 
device on plant grounds, the plant boundary.\1\ By including this 
clarification, PHMSA intends to minimize the need to reclassify 
existing facilities among operators that were applying that historical 
understanding on the boundary between in-plant piping and regulated 
pipeline facilities.
---------------------------------------------------------------------------

    \1\ PHMSA Letter of Interpretation to Ms. Kim Garold, Flint 
Hills Resources, No. PI-19-0017 (June 8, 2021).
---------------------------------------------------------------------------

    PHMSA intends to apply its prior interpretations, whether issued in 
the context of gas or hazardous liquid pipelines, to the proposed 
definition of ``in-plant piping systems'' in Sec.  192.3, including in 
determining the status of in-plant pipeline systems that cross a single 
public throughfare (e.g., a public road or rail line) (59 FR 33388, 
33389 (Jun. 28, 1994); PI-19-0017 (Jun. 8, 2021)). However, PHMSA seeks 
comments on whether those interpretations should be codified in the 
text of part 192.

II. Regulatory Analysis and Notices

A. Legal Authority

    This proposed rule is published under the authority of the 
Secretary of Transportation set forth in the Federal Pipeline Safety 
Laws (49 U.S.C. 60101 et seq.) and delegated to the PHMSA Administrator 
pursuant to 49 CFR 1.97.

B. Executive Order 12866; Regulatory Planning and Review

    Executive Order (E.O.) 12866 (``Regulatory Planning and Review''; 
58 FR 51735 (Oct. 4, 1993)), as implemented by DOT Order 2100.6B 
(``Policies and Procedures for Rulemaking''), requires agencies to 
regulate in the ``most cost-effective manner,'' to make a ``reasoned 
determination that the benefits of the intended regulation justify its 
costs,'' and to develop regulations that ``impose the least burden on 
society.'' DOT Order 2100.6B specifies that regulations should 
generally ``not be issued unless their benefits are expected to exceed 
their costs.'' In arriving at those conclusions, E.O. 12866 requires 
that agencies should consider ``both quantifiable measures . . . and 
qualitative measures of costs and benefits that are difficult to 
quantify'' and ``maximize net benefits . . . unless a statute requires 
another regulatory approach.'' E.O. 12866 also requires that ``agencies 
should assess all costs and benefits of available regulatory 
alternatives, including the alternative of not regulating.'' DOT Order 
2100.6B directs that PHMSA and other Operating Administrations must 
generally choose

[[Page 28608]]

the ``least costly regulatory alternative that achieves the relevant 
objectives'' unless required by law or compelling safety need.
    E.O. 12866 and DOT Order 2100.6B also require that PHMSA submit 
``significant regulatory actions'' to the Office of Information and 
Regulatory Affairs (OIRA) within the Executive Office of the 
President's Office of Management and Budget (OMB) for review. This 
proposed rule is a not significant regulatory action pursuant to E.O. 
12866; it also has not designated this rule as a ``major rule'' as 
defined by the Congressional Review Act (5 U.S.C. 801 et seq.).
    PHMSA has complied with the requirements in E.O. 12866 as 
implemented by DOT Order 2100.6B and preliminarily determined that this 
proposed rule will result in cost savings by reducing regulatory 
burdens and regulatory uncertainty for gas pipeline facility operators 
by clarifying jurisdictional boundaries within certain types of 
facilities, avoiding duplicative or contradictory Federal requirements. 
PHMSA expects those cost savings will also result in reduced costs for 
the public to whom pipeline operators generally transfer a portion of 
their compliance costs. The cost savings of this rulemaking could not 
be quantified.

C. Executive Orders 14192 and 14219

    This NPRM is expected to be a deregulatory action pursuant to E.O. 
14192 (``Unleashing Prosperity Through Deregulation''; (90 FR 9065 
(Feb. 6, 2025)). PHMSA estimates that the total costs of the NPRM on 
the regulated community will be less than zero. Nor does this 
rulemaking implicate any of the factors identified in section 2(a) of 
E.O. 14219 (``Ensuring Lawful Governance and Implementing the 
President's `Department of Government Efficiency' Deregulatory 
Initiative'') indicative that a regulation is ``unlawful . . . [or] 
that undermine[s] the national interest.'' (90 FR 10583 (Feb. 25, 
2025).

D. Energy-Related Executive Orders 13211, 14154, and 14156

    The President has declared in E.O. 14156 (``Declaring a National 
Energy Emergency''; (90 FR 8353 (Jan. 29, 2025)) a national emergency 
to address America's inadequate energy development production, 
transportation, refining, and generation capacity. Similarly, E.O. 
14154 (``Unleashing American Energy,'' (90 FR 8353 (Jan. 29, 2025)) 
asserts a Federal policy to unleash American energy by ensuing access 
to abundant supplies of reliable, affordable energy from (inter alia) 
the removal of ``undue burden[s]'' on the identification, development, 
or use of domestic energy resources such as PHMSA-jurisdictional gasses 
and hazardous liquids. PHMSA preliminarily finds this proposed rule is 
consistent with each of E.O. 14156 and E.O. 14154. The proposed rule 
will give affected pipeline operators relief from complying with the 
pipeline safety requirements for in-plant piping. PHMSA therefore 
expects the regulatory amendments in this proposed rule will in turn 
increase national pipeline transportation capacity and improve pipeline 
operators' ability to provide abundant, reliable, affordable natural 
gas in response to residential, commercial, and industrial demand.
    However, this proposed rule is not a ``significant energy action'' 
under E.O. 13211 (``Actions Concerning Regulations That Significantly 
Affect Energy Supply, Distribution, or Use''; (66 FR 28355 (May 22, 
2001)), which requires Federal agencies to prepare a Statement of 
Energy Effects for any ``significant energy action.'' Because this 
proposed rule is not a significant action under E.O. 12866, it will not 
have a significant adverse effect on supply, distribution, or energy 
use, as further discussed in the RIA; OIRA has therefore not designated 
this proposed rule as a significant energy action.

E. Executive Order 13132: Federalism

    PHMSA analyzed this proposed rule in accordance with the principles 
and criteria contained in E.O. 13132 (``Federalism''; 64 FR 43255 (Aug. 
10, 1999)) and the Presidential Memorandum (``Preemption'') published 
in the Federal Register on May 22, 2009 (74 FR 24693). E.O. 13132 
requires agencies to assure meaningful and timely input by State and 
local officials in the development of regulatory policies that may have 
``substantial direct effects on the States, on the relationship between 
the National Government and the States, or on the distribution of power 
and responsibilities among the various levels of government.''
    While the proposed rule may (when finalized) operate to preempt 
some State requirements, it would not impose any regulation that 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. Section 
60104(c) of Federal Pipeline Safety Laws prohibits certain State safety 
regulation of interstate pipelines. Under Federal Pipeline Safety Laws, 
States that have submitted a current certification under section 
60105(a) can augment Federal pipeline safety requirements for 
intrastate pipelines regulated by PHMSA but may not approve safety 
requirements less stringent than those required by Federal law. A State 
may also regulate an intrastate pipeline facility that PHMSA does not 
regulate. The preemptive effect of the regulatory amendments in this 
proposed rule is limited to the minimum level necessary to achieve the 
objectives of the Federal Pipeline Safety Laws. Therefore, the 
consultation and funding requirements of E.O. 13132 do not apply.

F. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
Federal agencies to conduct a Final Regulatory Flexibility Analysis 
(FRFA) for a proposed rule subject to notice-and-comment rulemaking 
under the APA unless the agency head certifies that the proposed rule 
in the rulemaking will not have a significant economic impact on a 
substantial number of small entities. E.O. 13272 (``Proper 
Consideration of Small Entities in Agency Rulemaking''; 67 FR 53461 
(Aug. 16, 2002)) obliges agencies to establish procedures promoting 
compliance with the Regulatory Flexibility Act. DOT posts its 
implementing guidance on a dedicated web page. This proposed rule was 
developed in accordance with E.O. 13272 and DOT implementing guidance 
to ensure compliance with the Regulatory Flexibility Act. The proposed 
rule is expected to reduce regulatory burdens. Therefore, PHMSA 
certifies the proposed rule (if finalized) will not have a significant 
impact on a substantial number of small entities.

G. Unfunded Mandates Reform Act of 1995

    The Unfunded Mandates Reform Act (UMRA, 2 U.S.C. 1501 et seq.) 
requires agencies to assess the effects of Federal regulatory actions 
on State, local, and Tribal governments, and the private sector. For 
any proposed or final rule that includes a Federal mandate that may 
result in the expenditure by state, local, and Tribal governments, in 
the aggregate of $100 million or more (in 1996 dollars) in any given 
year, the agency must prepare, amongst other things, a written 
statement that qualitatively and quantitatively assesses the costs and 
benefits of the Federal mandate.
    This proposed rule does not impose unfunded mandates under UMRA. 
PHMSA does not expect the proposed rule will result in costs of $100 
million or more (in 1996 dollars) per year for

[[Page 28609]]

either State, local, or Tribal governments, or to the private sector.

H. National Environmental Policy Act

    The National Environmental Policy Act (NEPA, 42 U.S.C. 4321 et 
seq.) requires that Federal agencies assess and consider the impact of 
major Federal actions on the human and natural environment.
    PHMSA analyzed this proposed rule in accordance with NEPA and 
issues this draft Finding of No Significant Impact (FONSI), because it 
has preliminarily determined that the rulemaking will not adversely 
affect safety and therefore will not significantly affect the quality 
of the human and natural environment. The public is invited to comment 
on the impact of the proposed action.

I. Executive Order 13175

    PHMSA analyzed this proposed rule according to the principles and 
criteria in E.O. 13175 (``Consultation and Coordination with Indian 
Tribal Governments''; 65 FR 67249 (Nov. 9, 2000)) and DOT Order 5301.1A 
(``Department of Transportation Tribal Consultation Polices and 
Procedures''). E.O. 13175 requires agencies to assure meaningful and 
timely input from Tribal government representatives in the development 
of rules that significantly or uniquely affect Tribal communities by 
imposing ``substantial direct compliance costs'' or ``substantial 
direct effects'' on such communities or the relationship or 
distribution of power between the Federal government and Tribes.
    PHMSA assessed the impact of the proposed rule and determined that 
it will not significantly or uniquely affect Tribal communities or 
Indian Tribal governments. The rulemaking's regulatory amendments have 
a broad, national scope; therefore, this proposed rule will not 
significantly or uniquely affect Tribal communities, much less impose 
substantial compliance costs on Native American Tribal governments or 
mandate Tribal action. For these reasons, PHMSA has concluded that the 
funding and consultation requirements of E.O. 13175 and DOT Order 
5301.1A do not apply.

J. Paperwork Reduction Act

    The Paperwork Reduction Act (44 U.S.C. 3501 et seq.) and its 
implementing regulations at 5 CFR 1320.8(d) requires that PHMSA provide 
interested members of the public and affected agencies with an 
opportunity to comment on information collection and recordkeeping 
requests. This rulemaking will not create, amend, or rescind any 
existing information collections.

K. Executive Order 13609 and International Trade Analysis

    E.O. 13609 (``Promoting International Regulatory Cooperation''; 77 
FR 26413 (May 4, 2012)) requires agencies consider whether the impacts 
associated with significant variations between domestic and 
international regulatory approaches are unnecessary or may impair the 
ability of American business to export and compete internationally. In 
meeting shared challenges involving health, safety, labor, security, 
environmental, and other issues, international regulatory cooperation 
can identify approaches that are at least as protective as those that 
are or would be adopted in the absence of such cooperation. 
International regulatory cooperation can also reduce, eliminate, or 
prevent unnecessary differences in regulatory requirements.
    Similarly, the Trade Agreements Act of 1979 (Pub. L. 96-39), as 
amended by the Uruguay Round Agreements Act (Pub. L. 103-465), 
prohibits Federal agencies from establishing any standards or engaging 
in related activities that create unnecessary obstacles to the foreign 
commerce of the United States. For purposes of these requirements, 
Federal agencies may participate in the establishment of international 
standards, so long as the standards have a legitimate domestic 
objective, such as providing for safety, and do not operate to exclude 
imports that meet this objective. The statute also requires 
consideration of international standards and, where appropriate, that 
they be the basis for U.S. standards.
    PHMSA engages with international standards setting bodies to 
protect the safety of the American public. PHMSA has assessed the 
effects of the proposed rule and has determined that its regulatory 
amendments will not cause unnecessary obstacles to foreign trade.

L. Cybersecurity and Executive Order 14028

    E.O. 14028 (``Improving the Nation's Cybersecurity''; 86 FR 26633 
(May 17, 2021)) directed the Federal government to improve its efforts 
to identify, deter, and respond to ``persistent and increasingly 
sophisticated malicious cyber campaigns.'' PHMSA has considered the 
effects of the proposed rule and has determined that its regulatory 
amendments would not materially affect the cybersecurity risk profile 
for pipeline facilities.

List of Subjects in 49 CFR Part 191

    Pipeline Safety.

    For the reasons set forth above, PHMSA proposes to amend 49 CFR 
part 192 as follows:

3. In Sec.  192.3, add a definition for ``in-plant piping system'' in 
alphabetical order to read as follows:


Sec.  192.3  Definitions

* * * * *
    In-plant piping system means piping that is located on the grounds 
of a plant and used to move gas between plant facilities or between 
plant facilities and a pipeline or other mode of transportation, not 
including any device and associated piping that are necessary to 
control pressure in a pipeline. The point of demarcation between a 
pipeline and an in-plant piping system is the inlet of the pressure 
control device if the pipeline is moving gas out of the plant or the 
outlet of the pressure control device if the pipeline is moving gas 
into the plant. If there is no such pressure control device located on 
the grounds of the plant, an in-plant piping system extends to the 
plant boundary.
