I. Executive Summary

    PHMSA is publishing this advance notice of proposed rulemaking 
(ANPRM) to solicit stakeholder feedback on potential opportunities for 
amendment of its regulations governing the siting, design, 
installation, construction, inspection, testing, operation, and 
maintenance of LNG facilities at 49 CFR part 193. Those requirements 
have not been substantially revised for over two decades. In the years 
since, the U.S. LNG industry has become truly global in scale and 
geopolitical importance; the sophistication of technology and operating 
practices within LNG facilities regulated by PHMSA have similarly 
evolved at a breakneck pace. In recognition of these developments, 
Congress, the Government Accountability Office (GAO), and industry 
stakeholders have repeatedly called on PHMSA to update its part 193 
regulations to better align with current technologies, operational best 
practices, and lessons learned. In response to these recommendations 
and mandates, PHMSA now solicits stakeholder feedback on potential 
amendments to its part 193 LNG facility requirements that will inform a 
forthcoming notice of proposed rulemaking (NPRM) in this proceeding.

II. Background

    PHMSA's last significant amendments to its part 193 regulations 
governing LNG facilities date to 2004.\1\ Current regulations rely 
heavily on the 2001 edition of a consensus industry standard--National 
Fire Protection Association (NFPA) 59A, ``Standard for the Production, 
Storage, and Handling of Liquefied Natural Gas'' (NFPA 59A) \2\--that 
has since been updated multiple times.
---------------------------------------------------------------------------

    \1\ Research and Special Projects Administration, ``Pipeline 
Safety: Liquefied Natural Gas Facilities; Clarifying and Updating 
Safety Standards,'' 69 FR 11336 (Mar. 10, 2004).
    \2\ PHMSA elsewhere in this ANPRM refers to specific editions of 
NFPA 59A by adding the date of those editions as a suffix; by way of 
example, ``NFPA 59A-2023'' refers to the 2023 edition of NFPA 59A.
---------------------------------------------------------------------------

    In the interim, the U.S. LNG industry has emerged as a driver of 
the U.S. domestic economy, a lynchpin of international commerce, and a 
critical instrument for advancing U.S. strategic interests. A recent 
study predicts the U.S. LNG industry over the next 16 years will 
contribute around $1.3 trillion to U.S. Gross Domestic Product--
including more than $2.5 trillion in total revenues for U.S. 
businesses, $165 billion in Federal and State tax revenues, more than 
$500 billion in labor income, and support an average of nearly a half-
million U.S. jobs annually.\3\

U.S. LNG Industry Impact Study--Phase 1 (Dec. 2024), available at 
https://www.spglobal.com/en/research-insights/special-reports/major-new-us-industry-at-a-crossroads-us-lng-impact-study-phase-1.
---------------------------------------------------------------------------

    Meanwhile, the United States is the largest international exporter 
of LNG, is the source of roughly 22% of worldwide LNG supply, and is a 
critical supplier to energy markets in Europe and Asia (the top 
destinations for U.S. LNG exports). U.S. LNG exports play an outsized 
role in advancing U.S. strategic interests, improving the nation's 
trade balance, and supporting the energy needs of resource-constrained 
strategic allies.
    U.S. LNG facility technologies and operations have evolved 
alongside the expansion and growing importance of the industry. When 
PHMSA issued its last major updates to the part 193 regulations in 
2004, most LNG facilities regulated by PHMSA were relatively small 
facilities focused on the U.S. domestic market: LNG import facilities 
and ``peak-shaving'' facilities supporting local gas distribution 
companies. But even as those LNG facilities remain common, there is 
increasing interest within the U.S. domestic LNG market for small-scale 
or mobile or temporary LNG facilities supporting novel applications, 
including (but not limited to): marine bunkering for fueling maritime 
vessels; trucking fleet transportation fueling; alternative gas supply 
for pipeline testing activity; off-grid electric power and heat 
generation; and electric power continuity for data centers. At the same 
time, the re-orientation of the U.S. LNG industry toward international 
markets has resulted in the construction of a number of massive, 
capital-intensive, and increasingly sophisticated LNG export terminals. 
The LNG industry has compiled and memorialized the lessons learned and 
best practices in designing, constructing, and operating each of these 
types of LNG facilities over the last two decades in consensus industry 
standards--culminating in the latest edition of NFPA 59A that was 
published in 2023.
    Recognizing that PHMSA regulations have not kept pace with 
technological innovation and best practices in the LNG industry, 
policymakers and other stakeholders have repeatedly called on PHMSA to 
update its part 193 regulations. GAO in 2020 criticized PHMSA for not 
having conducted a standards-specific review of its part 193 
regulations for nearly two decades and recommended that PHMSA consider 
incorporating by reference more recent editions of consensus industry 
standards such as NFPA 59A.\4\ Section 27 of the Protecting our 
Infrastructure of Pipelines and Enhancing Safety Act of 2016 (PIPES Act 
of 2016, Pub. L. 114-183) directed PHMSA to update its minimum safety 
standards for ``permanent, small scale'' LNG facilities.\5\ 
Subsequently, section 110 of the Protecting our Infrastructure of 
Pipelines and Enhancing Safety Act of 2020 (PIPES Act of 2020, Pub. L. 
116-2600) directed PHMSA to update the minimum safety standards by 
December 27, 2023, to impose a risk-based regulatory approach for 
large-scale LNG facilities, other than peak-shaving facilities.\6\

    Meanwhile, President Trump in his first term issued Executive Order 
(E.O.) 13868 ``Promoting Energy Infrastructure and Economic Growth,'' 
directing PHMSA to issue a final rule updating its part 193 regulations 
no later than May 2020.\7\ President Trump has in the current term 
issued E.O. 14192, ``Unleashing Prosperity Through Deregulation,'' 
requiring agencies to identify opportunities to alleviate unnecessary 
regulatory compliance burdens imposed on industry and the general 
public, E.O. 14154, ``Unleashing American Energy,'' requiring agencies 
to reduce undue burdens on the identification, development, or use of 
domestic energy resources; and E.O. 14156, ``Declaring a National 
Energy Emergency,'' to ensure the integrity and

---------------------------------------------------------------------------

    PHMSA has also received petitions for rulemaking and other requests 
from industry trade groups calling on PHMSA to update its part 193 
regulations to address various alleged shortcomings, including 
incorporating by reference more recent editions of NFPA 59A.
    To develop an NPRM responding to the above recommendations and 
mandates, PHMSA is soliciting stakeholder feedback on, among other 
things: (1) the topics listed in section III below; (2) potential 
amendments to its part 193 LNG facility requirements, including any 
amendments identified by stakeholders; (3) the appropriateness of those 
amendments for different types of LNG facilities (including export 
terminals and peak-shaving facilities); (4) the incremental compliance 
costs and benefits (including benefits pertaining to avoided compliance 
costs, safety harms, and environmental harms) anticipated from those 
amendments; and (5) the technical feasibility, reasonableness, cost-
effectiveness, and practicability of those potential amendments. PHMSA 
plans to hold a public meeting in the near future to supplement or to 
clarify the materials received in response to this ANPRM.
    With respect to incremental cost and benefit information, PHMSA is 
seeking per-unit, aggregate, and programmatic (both one-time 
implementing and recurring) data. Explanation of the bases or 
methodologies employed in generating cost and benefit data, including 
data sources, assumptions (e.g., calculations), is valuable so that 
PHMSA can explain the support for any estimates it is able to provide 
that accompany a proposed rule, and other commenters may weigh in on 
the validity and accuracy of the data. Please also identify the 
baseline (e.g., a particular edition of a consensus industry standard 
such as NFPA 59A; widespread voluntary operator practice; or 
documentation of sample surveys and other operator level data or 
information) from which those incremental costs and benefits arise. 
When estimates are approximate or uncertain, consider using a range or 
specifying the distribution in other ways.
    When responding to a specific question below please note the topic 
letter and question number in your comment. PHMSA will review and 
evaluate all comments received, as well as late-filed comments to the 
extent practicable.

III. Topics Under Consideration

    A. PHMSA's enabling statute at 49 U.S.C. 60101(a)(14) defines an 
LNG facility subject to PHMSA's authority as ``a gas pipeline facility 
used for transporting or storing liquefied natural gas, or for 
liquefied natural gas conversion, in interstate or foreign commerce.'' 
Excluded from this definition is ``any part of a structure or equipment 
located in navigable waters.''
    1. What regulatory amendments could improve or clarify the 
applicability of PHMSA's part 193 regulations to LNG facilities under 
its statutory authority? Should PHMSA's regulations be amended to 
clarify the boundaries of its regulatory authority with respect to some 
or all categories of LNG facilities? Which provisions (including 
regulatory definitions) merit revision and how should they be modified?
    2. For LNG facilities over which PHMSA shares regulatory authority 
with another Federal agency, should PHMSA consider an LNG facility's 
compliance with analogous regulatory requirements or guidance issued by 
those other agencies in evaluating compliance with existing part 193 
requirements or (should they be incorporated by reference into part 193 
regulations) NFPA 59A-2023? Please identify those analogous 
requirements of PHMSA and other Federal agencies.
    B. The term ``LNG facility'' is defined in PHMSA's enabling statute 
at 49 U.S.C. 60101(a)(14) and PHMSA implementing regulations at 49 CFR 
193.2007. LNG facilities subject to part 193 requirements include 
``baseload'' facilities, ``peak-shaver'' facilities, ``temporary'' or 
``mobile'' LNG facilities, and ``satellite'' LNG facilities.
    1. How many of each of these categories of LNG facilities are 
projected to come into existence over the next two decades? What 
function(s) do they each currently serve in the interstate natural gas 
transportation system, and are there any emerging applications for 
those facilities?
    2. Are there material differences in the characteristics (e.g., 
capacity or size; physical processes) of and among those categories of 
LNG facilities that merit distinguishable treatment under part 193? 
What proportion of each category of LNG facilities are operated by 
``small entities'' (small businesses, small organizations, or small 
government jurisdictions) \9\ as defined in the Regulatory Flexibility 
Act (5 U.S.C. 6010 et seq.) and its implementing regulations?
---------------------------------------------------------------------------

    \9\ For example, ``small businesses'' include those operators 
that employ fewer than 1500 employees or which have annual revenue 
less than $40 million; ``small government jurisdictions'' are those 
with a population of less than 50,000 persons.
---------------------------------------------------------------------------

    C. LNG facility reporting requirements are set forth at 49 CFR 
193.2011.
    1. Is there information required in the annual, incident, and 
safety related condition reports required by PHMSA regulations with 
limited or no safety value any of the categories of part 193-regulated 
LNG facilities?
    2. Is there information required in the reports that is duplicative 
with the information required to be submitted to other State or Federal 
regulatory authorities?
    3. What incremental, per-unit costs and benefits may arise from 
amending Sec.  193.2011 to clarify that safety-related condition 
reporting would be required not only for ``in-service'' LNG facilities, 
but also safety-related conditions that occur during commissioning and 
initial start-up?
    D. Current part 193 regulations incorporate much of NFPA 59A-2001's 
provisions pertinent to LNG facility siting (Sec.  193.2051), design 
(Sec.  193.2101(a)), construction (Sec.  193.2301), equipment (Sec.  
193.2401), and fire protection (Sec.  193.2801).
    1. Stakeholders have asserted that compliance with provisions of 
NFPA 59A-2001 has become increasingly impracticable as vendors and the 
industry itself employ more recent consensus industry standards in 
their activities. Please describe noteworthy examples of tension 
between NFPA 59A-2001 provisions referenced in current PHMSA 
regulations and more recent consensus industry standards. What 
incremental, per-unit costs (including, but not limited to, those 
arising from personnel having to compare operator practices with 
provisions of NFPA 59A-2001 referenced in current PHMSA regulations) 
arise from operators having to navigate those tensions?
    2. Should PHMSA consider a narrow rulemaking to update only the 
NFPA 59A standard to the 2023 edition and pursuing a broader part 193 
update afterward? What would the incremental costs and benefits be of 
an update of the NFPA 59A standard to 2023?
    3. To what extent do different categories of LNG facility operators 
generally comply with other NFPA 59A-2001 provisions (e.g., those 
governing operating and maintenance) not explicitly incorporated by 
reference in part 193? With which of those NFPA 59A-2001 provisions do 
different categories of LNG facility operators

[[Page 18952]]

generally comply? With which do they generally not comply?
    4. To what extent do different categories of LNG facility operators 
generally comply with provisions in more recent editions of NFPA 59A? 
If so, which edition (e.g., NFPA 59A-2019 or NFPA 59A-2023) do 
operators generally follow? Do operators generally conform their 
activities to the entirety of those more recent editions, or do they 
follow specific chapters or paragraphs of those more recent editions, 
but not others? Do operators conform to more recent editions of NFPA 
59A voluntarily or due to regulatory requirements imposed by another 
State or Federal regulatory authority?
    5. Part 193 regulations in several places broadly incorporate 
pertinent NFPA 59A-2001 requirements provided they do not conflict with 
specific part 193 provisions; such language appears in Subparts B 
(``Siting''), C (``Design''), D (``Construction''), E (``Equipment''), 
and I (``Fire Protection). What incremental, per-unit costs and 
benefits would arise from substituting NFPA 59A-2023 provisions for the 
current reference to NFPA 59A-2001 provisions (or superseding part 193 
provisions) in each of those subparts of part 193? Should PHMSA exclude 
some NFPA 59A-2023 provisions from incorporation by reference in those 
subparts? To which categories of LNG facilities should any NFPA 59A-
2023 provisions pertinent to those subparts apply?
    6. What incremental, per-unit costs and benefits would arise should 
PHMSA propose to incorporate by reference the entirety of NFPA 59A-
2023? Please provide those estimated, incremental costs and benefits on 
a per-chapter basis where possible, highlighting provisions in each 
NFPA 59A-2023 chapter for which compliance would be particularly 
burdensome or costly for particular categories of LNG facility 
operators.
    7. Which mandatory provisions of NFPA 59A-2023 should be made 
permissive if incorporated into the PHMSA's part 193 regulations? Are 
there certain mandatory elements of NFPA 59A-2023 that should remain 
mandatory for some categories of LNG facilities but not others? Should 
any non-mandatory provisions in NFPA 59A-2023 be mandatory, and what 
incremental, per-unit costs and benefits would arise?
    8. What incremental, per-unit costs and benefits would arise from 
PHMSA integrating NFPA 59A-2023's references to ``hazardous fluid'' 
alongside references to ``LNG'' and ``natural gas'' throughout part 
193?
    9. What incremental, per-unit costs and benefits would arise in 
connection with the incorporation by reference in part 193 of NFPA 59A-
2023 chapter 14 requirements governing ``mobile and temporary LNG 
facilities''? Are there particular requirements in NFPA 59A-2023 
chapter 14 that would entail noteworthy incremental, per-unit 
compliance costs and benefits?
    10. Are the criteria for ``stationary, small-scale LNG facilities'' 
in paragraph 17.1.2 of NFPA 59A-2023 appropriate? What would be the 
incremental, per-unit costs and benefits of adopting these provisions 
relative to current part 193 requirements (including referenced 
provisions in NFPA 59A-2001)? Are there particular requirements in NFPA 
59A-2023 pertinent to small-scale LNG facilities that would lead to 
incremental, per-unit costs and benefits?
    11. What would be the incremental, per-unit costs and benefits to 
operators from installing dikes around American Society of Mechanical 
Engineers (ASME)-compliant single-walled containers and membrane-
containment tank systems? How many single-walled ASME containers, 
single-walled ASME vessels, and membrane-containment tank systems would 
different categories of LNG facilities have on average?
    12. What are the incremental, per-unit costs and benefits to 
operators of different categories of LNG facilities from utilizing the 
design spill parameters for pipe-in-pipe systems in Frequently Asked 
Question (FAQ) #DS2(C) within PHMSA guidance for LNG facilities? \10\

---------------------------------------------------------------------------

    13. What would be the initial and annual recurring incremental, 
per-unit costs and benefits to operators from generation and 
implementation of a robust mechanical and electrical lockout program in 
different categories of LNG facilities?
    14. Are there any PHMSA interpretations of its part 193 regulations 
\11\ whose safety value does not justify any associated compliance 
costs for each category of LNG facilities? If so, what are the 
associated compliance costs? Are there any interpretations that merit 
codification in part 193 regulations?

    E. GAO in its August 2020 report identified consensus industry 
standards other than NFPA 59A listed in Sec.  193.2013 and currently 
incorporated by reference throughout PHMSA's part 193 regulations 
meriting updating to more recent editions.
    1. Please describe current operator compliance strategies with 
respect to those standards. Do some or all operators generally comply 
with the older editions currently referenced in part 193 regulations, 
more recent editions, or both? If operators comply with a more recent 
edition, which one--the latest edition or some intermediate edition? If 
some operators but not others comply with each of those updated 
standards, are there certain categories of LNG facilities that 
generally comply with more recent standards?
    2. To which edition of each standard should PHMSA update its part 
193 regulations? Please provide technical, safety, and economic reasons 
for updating part 193 regulations to reference a particular edition of 
each standard.
    3. Please estimate any incremental, per-unit costs and benefits 
that would arise from updating each of those standards to a more recent 
standard. Are there particular provisions of those standards that 
entail noteworthy incremental costs and benefits?
    4. Are there specific provisions or sections in those updated 
editions that PHMSA should exclude when incorporating those standards 
by reference with respect to some or all part 193-regulated LNG 
facilities? Please provide the technical, safety, and economic reasons 
for such an exclusion.
    5. Are there any updates in development for consensus industry 
standards currently incorporated by reference in part 193 regulations 
that could merit inclusion in this rulemaking? Please provide the 
technical, safety, and economic reasons for inclusion of those 
forthcoming updates.
    F. Are there any consensus industry standards pertinent to part 
193-regulated LNG facilities that PHMSA should consider incorporating 
by reference for the first time?
    1. Please identify any such standards, noting the edition to be 
incorporated by reference and any portions of those standards that 
should be excluded from such incorporation, along with any technical, 
safety, and economic justification.
    2. Which provisions of part 193 should reference those standards?
    3. Please estimate any incremental, per-unit costs and benefits 
that would arise from incorporating by reference standard. Are there 
particular provisions of those standards that entail noteworthy 
incremental costs and benefits?

[[Page 18953]]

    G. Section 110 of the PIPES Act of 2020 requires PHMSA to update 
part 193 operating and maintenance standards for ``large-scale'' LNG 
facilities (other than peak shaving facilities) to provide for a 
``risk-based regulatory approach'' that PHMSA ensures will achieve an 
equivalent level of safety to current, prescriptive part 193 operating 
and maintenance standards.
    1. What is the appropriate metric and threshold for determining 
whether an LNG facility is a large-scale LNG facility and why is it 
appropriate?
    2. For which provisions of part 193, subparts F (Operations) and G 
(Maintenance) should a risk-based regulatory approach provide an 
alternative? What would be the incremental, per-unit cost benefits from 
substitution of a risk-based regulatory approach, estimated for each of 
those part 193, subparts F and G provisions?
    3. Are there particular regulatory or conceptual frameworks or 
consensus industry standards or protocols that are appropriate for use 
in designing implementation plans for an alternative risk-based 
regulatory approach? Are those frameworks or consensus industry 
standards or protocols employed by ``large-scale LNG facilities--and if 
so, how widely? Are such frameworks or standards employed voluntarily 
or pursuant to legal requirements (e.g., the terms and conditions of a 
FERC certificate of convenience and necessity)? Please provide 
technical and safety reasons (to include pertinent data or studies) for 
the appropriateness of those frameworks or industry standards.
    4. What should be the relationship between an LNG facility 
implementation plan and the Emergency Response Plan required under 
section 3(a) of the Natural Gas Act (15 U.S.C. 717b-1)?
    5. What should be the required content and information in LNG 
facility implementation plans submitted to PHMSA? What would be the 
incremental, per-unit unit cost for development of implementation 
plans?
    6. What would be the annual incremental, per-unit costs for 
operators' execution of implementation plans? Please provide such an 
estimate for each of the elements (e.g., employee and contractor 
training; quality assurance programs) listed in section 110(c).
    7. What processes should PHMSA employ in reviewing and evaluating 
operator submissions? Are there models for those processes elsewhere in 
current PHMSA regulations? If so, how are those models appropriate for 
use in connection with LNG facility implementation plans? Are there 
elements of those models that would be inappropriate for use in 
connection with LNG facility implementation plans?
    8. What factors should inform PHMSA's review of LNG facility 
implementation plans?

PHMSA and other agencies to reduce regulatory burdens on the U.S. 
energy industry.
    1. Are there current aspects of PHMSA regulations that are 
particularly burdensome on the ability of industry to operate LNG 
facilities that PHMSA should consider amending or rescinding?
    2. Are there areas that PHMSA could add regulatory text that would 
reduce costs on operators without reducing safety outcomes?
    3. Which aspects of current PHMSA regulations do operators find 
outdated or unnecessary because industry practice or existing industry 
guidelines are an equivalent or better standard both for cost savings 
and safety outcomes?
    4. How can PHMSA best design a rulemaking to update its part 193 
regulations for LNG facilities to be deregulatory and lead to cost 
savings for the industry?

    Issued in Washington, DC, on April 28, 2025, under authority 
delegated in 49 CFR 1.97.
