PHMSA Proposes Updating Pipeline Property Damage Reporting Definition

Content

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

PHMSA proposes to revise the definition of property damage for determining when a release from a gas, hazardous liquid, or
carbon dioxide pipeline facility meets the definition of a reportable incident or accident, including for immediate notifications
to the National Response Center. This NPRM addresses comments received in response to a now-withdrawn direct final rule covering
the same topic.

SUPPLEMENTARY INFORMATION:

I. General Discussion

On July 1, 2025, PHMSA published a direct final rule (DFR) clarifying the property damage thresholds that apply in determining
whether a release is a reportable incident pursuant to 49 CFR 191.9 or 191.15 or reportable accident pursuant to 49 CFR 195.50(e)
to exclude certain indirect costs associated with accessing the facility to perform repairs (90 FR 28050 (July 1, 2025)).
The DFR would have also adopted for hazardous liquid and carbon dioxide pipeline accident reporting under Part 195 the inflation
adjustment methodology that was previously adopted for reporting gas pipeline incidents in § 191.3 and Appendix A to Part
191. PHMSA received four comments from the public in response to the DFR, including adverse comments as defined in 49 CFR
190.339(b). PHMSA therefore withdrew the DFR in accordance with the Agency's DFR procedures in § 190.339. For the reasons
described in the DFR and this NPRM, PHMSA reproposes the amendments in the DFR with revisions to address public comments.

The American Petroleum Institute, the Liquid Energy Pipeline Association, and Enbridge submitted comments noting that the
DFR creates a misalignment between the property damage criterion for submitting 30-day reports of accidents under § 195.50
and the immediate notifications to the National Response Center (NRC) under § 195.52. (1 2) In comparison, the requirements for NRC notifications for gas pipeline incidents in § 191.5 cross-reference the incident definition
in § 191.3 and, therefore, the criteria remain aligned. Enbridge also recommended an editorial correction to a cross-reference
in Appendix D to Part 195. PHMSA notes that the omission of updates for the NRC reporting criteria in § 195.52 was not intended.

The Pipeline Safety Trust (PST) and the Environmental Defense Fund (EDF) submitted comments objecting to the DFR on procedural
grounds. (3 4) These commenters also raised concern that the revised property damage threshold for reporting accidents and other clarifications
to the property damage definition would reduce the amount of safety data available to the public and to PHMSA. PST commented
that it was unclear whether the DFR applied to carbon dioxide pipelines and raised concerns that that the accident criteria
already filter out “many large and potentially dangerous safety-related

events.” Both PST and EDF commented that reducing the number of accident reports submitted to PHMSA reduces the value of the
database, particularly for trend analysis, and undermines Federal and public oversight.

PHMSA is addressing procedural concerns raised by public comments by publishing this NPRM with a risk assessment (preliminary
regulatory impact analysis (PRIA)). PHMSA also emphasizes that accident report and immediate notice requirements in §§ 195.50
and 195.52, and therefore any revisions to those requirements, apply to both hazardous liquid and carbon dioxide pipelines.
PHMSA maintains that, under the proposed accident definition, consequential releases remain reportable. The other criteria
for fire or explosion, a release of five gallons or more (or five barrels (210 gallons) for certain contained releases), and
injury resulting in death or hospitalization remain reportable regardless of a change in the property damage definition. Accidents
with between $50,000 and $149,700 of property damage that do not meet the other criteria are definitionally the least-consequential
releases reported to PHMSA and would likely not have been reported when the accident definition was put into place. Incidents
and accidents where the sole consequences are temporary removal of pavement, permit acquisition, and repair costs are even
less significant and likely do not warrant the urgent, detailed reporting required for incident and annual reports.

In addition, PHMSA disagrees with the comments it received that revising the property damage definition upsets trend analysis.
In fact, a static property damage criteria results in the incident or accident definition changing over time in inflation-adjusted
terms; PHMSA has historically accounted for this fact in trend analysis of “significant incidents” that filter out incidents
and accidents with less than $50,000 in costs in 1984 dollars. (5) Finally, regarding the cost of lost product in hazardous liquid and carbon dioxide pipeline accident reports, operators are
required to report estimated release volumes. The total cost of lost product can be derived from this information using current
or historical price information from sources such as the U.S. Energy Information Administration. Requiring this information
from the operator is not necessary.

For the reasons described above and set forth in the DFR, PHMSA reproposes the amendments it proposed in the DFR with revisions
to ensure the property damage criterion for NRC reporting in § 195.52 are consistent with accident reporting requirements
in § 195.50. This proposal is consistent with historical practice and avoids unnecessarily complicated reporting procedures.
As an alternative, PHMSA requests comment on replacing the immediate notice criteria in § 195.52(a)(1) through (a)(3) and
(a)(4) with a cross-reference to the accident criteria in § 195.50. PHMSA proposes to retain the water pollution criteria
for NRC reporting because it supports the implementation of oil spill response plan requirements in Part 194. The NPRM also
proposes editorial amendments to Appendix D to Part 195 to correct the cross-reference to § 195.50(e) and to include the cross-reference
to the amended § 195.52(a)(3). The proposals to adopt inflation-adjusted incident and accident definitions in parts 191 and
195 are otherwise unchanged.

This NPRM also includes the proposal to address National Association of Pipeline Safety Representatives Resolution 2021-01,
“A Resolution Seeking a Modification of PHMSA's Instructions for Incident Reporting for Gas Distribution, Gas Transmission,
and Gas Gathering Systems,” described in the DFR. Specifically, PHMSA proposes to revise the definitions of the terms incident
and accident to clarify that the costs associated with obtaining permits and removing or replacing infrastructure undamaged
by an event (e.g., the cost to temporarily remove pavement needed for access and repair activity) do not need to be included when calculating
the property damage reporting threshold. Though operators would still report indirect impacts as consequences on the incident
and accident report forms, those impacts do not determine if an event is reportable.

Finally, PHMSA proposes to revise the property damage criterion for gas pipelines to $149,700 in both § 191.3 and Appendix
A to Part 191 to align it with the proposed criterion for hazardous liquid pipelines. This property damage criterion value
is currently published on PHMSA's website and proposing to republish it in the regulations has no substantive effect other
than making it clearer that the property damage criteria in parts 191 and 195 are the same.

PHMSA, in a parallel action titled “Pipeline Safety: Adjustment to OPID Notifications for Construction,” is proposing to adopt
a similar inflation adjustment procedure to construction notifications based on year-on-year change in the Producer Price
Index (PPI) for construction materials. (6) PHMSA repeats the proposed Appendix D language in both NPRMs. (7)

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. Statutory Requirement and Executive Order 12866

The Federal Pipeline Safety Laws (49 U.S.C. 60102(b)) require that PHMSA prepare a risk assessment that identifies the costs
and benefits associated with a proposed regulatory change. E.O. 12866, Regulatory Planning and Review, as implemented by DOT Order 2100.6B (“Policies and Procedures for Rulemaking”) and DOT Order 2100.7 (“Ensuring Reliance upon
Sound Economic Analysis in Department of Transportation Policies, Programs, and Activities”), 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.” 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. DOT
Order 2100.6B also specifies that regulations should generally “not be issued unless their benefits are expected to exceed
their costs.” DOT Order 2100.7 requires that “all rulemaking activities shall be based on sound economic principles and analysis
supported by rigorous cost-benefit requirement.”

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; OMB 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 procedural and analytical requirements in E.O. 12866 as implemented by DOT Order 2100.6B and DOT
Order 2100.7, as well as the requirements in 49 U.S.C. 60102(b) and preliminarily determined that this NPRM will result in
some cost savings by reducing regulatory burdens associated with submitting urgent, detailed reports of low-consequence releases
from hazardous liquid and carbon dioxide pipelines. Based on historical incident data, PHMSA estimates that approximately
five incidents per year would meet the current reporting requirements but not the proposed requirements, out of an average
of over 370 incidents per year. The accompanying PRIA provides detailed estimates of the cost savings to operators from the
reduced reporting burden. PHMSA estimates that the changes in the proposed rule would result in cost savings of $5,235 annually.
PHMSA expects these cost savings may also result in reduced costs for the public to whom pipeline operators generally transfer
a portion of their compliance costs. PHMSA has also preliminarily determined that the NPRM will not have any adverse safety
and environmental effects since the average release of those incidents that would have been exempted was less than four gallons.

C. Executive Orders 14192 and 14219

This proposed rule, if finalized as proposed, is expected to be a deregulatory action pursuant to E.O. 14192, Unleashing Prosperity Through Deregulation. 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.”

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

The President has declared in E.O. 14156, Declaring a National Energy Emergency, a National emergency to address America's inadequate energy development production, transportation, refining, and generation
capacity. Similarly, E.O. 14154, Unleashing American Energy, 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 gases and hazardous liquids. PHMSA preliminarily finds this NPRM is consistent with each of E.O.
14156 and E.O. 14154. The NPRM will give affected pipeline operators relief from submitting detailed reports for relatively
minor releases.

However, this NPRM is not a “significant energy action” under E.O. 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use, which requires Federal agencies to prepare a Statement of Energy Effects for any “significant energy action.” Because this
NPRM is not a significant action under E.O. 12866, it will 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, and the Presidential Memorandum (“Preemption”) published in the
Federal Register
on May 22, 2009. 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.”

Though the NPRM 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 the Federal Pipeline Safety Laws prohibits certain State safety regulation of interstate
pipelines. Under the 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 (RFA, 5 U.S.C. 601 et seq.) requires Federal agencies to conduct an Initial Regulatory Flexibility Analysis (IRFA) for a NPRM subject to notice-and-comment
rulemaking unless the agency head certifies that the NPRM 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, obliges agencies to establish procedures promoting compliance with the RFA. DOT posts its implementing guidance on a dedicated
web page. (8)

This NPRM was developed in accordance with E.O. 13272 and DOT implementing guidance to ensure compliance with the RFA. The
NPRM is expected to reduce regulatory burdens by raising the monetary threshold for incidents to qualify as reportable, and
by clarifying which costs contribute to that threshold for operators who would otherwise be unaware. Further, the changes
proposed here are not expected to impose additional burdens on any operator. Therefore, PHMSA certifies this 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 ($203 million in 2024 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. PHMSA does not expect the NPRM will 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). PHMSA maintains
that under the proposed accident definition, consequential releases remain reportable. The other criteria for fire or explosion,
release of five gallons or more (or five barrels (210 gallons) for certain contained releases), and injury resulting in death
or hospitalization remain reportable regardless of a change in the property damage definition. In addition, because changing
the reportability threshold does not change the way operators respond to incidents, the environmental impacts do not change.
Therefore, PHMSA has preliminarily determined that the rulemaking will not adversely affect safety and 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 NPRM according to the principles and criteria in E.O. 13175, Consultation and Coordination with Indian Tribal Governments, 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 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 NPRM 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 NPRM 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.

PHMSA will submit an information collection revision request to OMB for approval based on the requirements in this NPRM. The
information collection is contained in the Federal Pipeline Safety Regulations. The following information is provided for
each information collection: (1) Title of the information collection; (2) OMB control number; (3) Current expiration date;
(4) Type of request; (5) Abstract of the information collection activity; (6) Description of affected public; (7) Estimate
of total annual reporting and recordkeeping burden; and (8) Frequency of collection. The information collection burdens for
the following information collections are estimated to be revised as follows:

1. Title: Transportation of Hazardous Liquids by Pipeline: Record keeping and Accident Reporting.

OMB Control Number: 2137-0047.

Current Expiration Date: 04/30/2026.

Abstract: This information collection covers general recordkeeping and the collection of information from hazardous liquid pipeline
operators for accident reports. PHMSA estimates that, due to the revised monetary damage threshold for reporting accidents,
operators will submit five fewer hazardous liquid accident reports per year. Therefore, PHMSA expects to eliminate five responses
and 60 hours from this information collection per year as a result of the provisions in the rule.

Affected Public: All hazardous liquid pipeline operators.

Annual Reporting and Recordkeeping Burden:

Total Annual Responses: 1,641 (1,646−5).

Total Annual Burden Hours: 53,717 (53,777−60).

Frequency of Collection: On Occasion.

K. Executive Order 13609 and International Trade Analysis

E.O. 13609, Promoting International Regulatory Cooperation, requires agencies to 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 NPRM 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, directs 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 NPRM and has determined that its regulatory amendments
would not materially affect the cybersecurity risk profile for pipeline facilities.

List of Subjects

Natural gas, Pipeline safety, Reporting and recordkeeping requirements.

Pipeline safety, Reporting and recordkeeping requirements.

In consideration of the foregoing, PHMSA proposes to amend 49 CFR parts 191 and 195 as follows:

PART 191—TRANSPORTATION OF NATURAL AND OTHER GAS BY PIPELINE; ANNUAL, INCIDENT, AND OTHER REPORTING

Regulatory Text 1. The authority citation for Part 191 continues to read as follows:

Authority:

30 U.S.C. 185(w)(3), 49 U.S.C. 5121, 60101 et seq., and 49 CFR 1.97.

1. Revise § 195.50(e) to read as follows:

§ 195.50 Reporting Accidents.

---

(e) Estimated property damage, including cost of clean-up and recovery and damage to the property of the operator or others—but
excluding each of the cost of lost product, the cost to acquire permits, and the cost to remove and replace non-operator infrastructure
that was not damaged by the release—exceeding $149,700. For adjustments for inflation observed in calendar year 2026 onwards,
changes to the reporting threshold will be posted on PHMSA's website. These changes will be determined in accordance with
the procedures in Appendix D to Part 195.

1. Revise § 195.52(a)(3) to read as follows:

(a) * * *

(3) Caused estimated property damage meeting the criteria in § 195.50(e).

---

1. In Part 195, add Appendix D to read as follows:

Appendix D to Part 195—Procedure for Determining Reporting Threshold

Each year after calendar year 2026, the Administrator will publish a notice on PHMSA's website announcing the updates to property
damage threshold criteria for accident reporting, National Response Center (NRC) notification, and construction notifications
that will take effect on July 1 of that year and will remain in effect until June 30 of the next year. The reporting threshold
used in this Part shall be determined in accordance with the following formula:

Where:

T r is the revised reporting threshold,

T p is the previous reporting threshold,

PI r is the average price index published by the Bureau of Labor Statistics each month during the most recent complete calendar
year. PHMSA will use the Consumer Price Indices for all Urban Consumers for accident reporting and NRC notifications and the
Producer Price Index for construction materials for OPID construction notifications.

PI p is the average price index for the calendar year used to establish the previous property damage criteria for accident reporting,
NRC notification, or construction notification, as appropriate.

Issued in Washington, DC, on April 22, 2026, under the authority delegated in 49 CFR 1.97. Paul J. Roberti, Administrator. [FR Doc. 2026-08079 Filed 4-23-26; 8:45 am] BILLING CODE 4910-60-P
