SUPPLEMENTARY INFORMATION:

I. General Discussion

    In this NPRM, PHMSA is proposing to revise the atmospheric 
corrosion control requirements in Sec.  192.481 for gas distribution 
service lines. Section 192.481(a)(2) generally requires operators to 
inspect service lines for evidence of atmospheric corrosion on a 5-year 
interval. If evidence of atmospheric corrosion is found during the most 
recent inspection, however, Sec.  192.481(d) requires operators to 
conduct the next inspection of a service line on a 3-year interval. 
Section 192.481(d) requires operators to conduct that 3-year 
reinspection even if the atmospheric corrosion found during the most 
recent inspection is remediated by replacing the affected portion of 
the service line.
    PHMSA has made a preliminary determination that requiring a 3-year 
reinspection for evidence of atmospheric corrosion is unnecessary and 
imposes an undue burden if an operator replaces the affected portion of 
a service line. Atmospheric corrosion presents minimal risk to new 
service lines, and operators can effectively manage that risk by 
conducting inspections on the standard 5-year interval. In addition, 
requiring operators to reinspect replaced service lines on a shorter 
interval imposes additional costs that are not justified by a 
corresponding benefit. Accordingly, PHMSA is proposing to amend Sec.  
192.481(d) by providing an exception to the 3-year reinspection 
interval for replaced service lines.

II. Regulatory Analysis and Notices

A. Legal Authority

    This NPRM 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 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 NPRM 
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 expects that this NPRM may result 
in cost savings by reducing regulatory burdens and regulatory 
uncertainty for pipeline facility operators related to the performance 
of atmospheric corrosion inspections and the reassessment intervals of 
such inspections. Those cost savings may 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.

[[Page 28605]]

C. Executive Orders 14192 and 14219

    This NPRM is expected to be a deregulatory action pursuant to 
Executive Order (E.O.) 12866 (``Regulatory Planning and Review''; 58 FR 
51735 (Oct. 4, 1993)). PHMSA estimates that the total costs of the NPRM 
on the regulated community would 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 finds this NPRM is consistent with each of 
E.O. 14156 and E.O. 14154. The NPRM would give affected pipeline 
operators reduced compliance obligations regarding atmospheric 
corrosion inspection intervals in response to pipe replacements. PHMSA 
therefore expects the regulatory amendments in this NPRM 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 NPRM 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.'' This NPRM is not a 
significant action under E.O. 12866 and also, it would not have a 
significant adverse effect on supply, distribution, or energy use; OIRA 
has therefore not designated this NPRM as a significant energy action.

E. Executive Order 13132: Federalism

    PHMSA analyzed this NPRM 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 ensure 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 this NPRM may 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 NPRM 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 an Initial Regulatory Flexibility Analysis 
(IRFA) for an NPRM subject to notice-and-comment rulemaking under the 
Administrative Procedure Act unless the agency head certifies that the 
proposed rule 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.\1\ This NPRM 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 rulemaking 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 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 NPRM does not impose unfunded mandates under UMRA because it 
does not result in costs of $100 million or more (in 1996 dollars) per 
year for 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 NPRM in accordance with NEPA and issues this 
draft Finding of No Significant Impact (FONSI), as 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.

I. Executive Order 13175

    PHMSA analyzed this NPRM 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 Policies 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

[[Page 28606]]

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 this NPRM and determined that it would 
not significantly or uniquely affect Tribal communities or Indian 
Tribal governments. The rulemaking's regulatory amendments have a 
broad, national scope; therefore, this NPRM would 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 NPRM would 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 this NPRM and has determined that its proposed regulatory 
amendments would 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 this NPRM and has determined that its regulatory amendments 
would not materially affect the cybersecurity risk profile for pipeline 
facilities.
