Pipeline Damage Reports Simplified: Focus on Direct Costs Only

Published Date: 4/24/2026

Proposed Rule

Summary

PHMSA is updating the rules about when pipeline companies must report damage from gas, liquid, or carbon dioxide leaks. The new definition of property damage focuses on direct costs, making reporting clearer and fairer. Pipeline operators should get ready to follow these changes and send their feedback by June 23, 2026—this could save time and money in reporting.

Analyzed Economic Effects

5 provisions identified: 4 benefits, 0 costs, 1 mixed.

Operators: Fewer Reports, Small Cost Savings

Pipeline operators would submit about five fewer hazardous liquid accident reports per year, reducing total annual responses by five and cutting information-collection burden by 60 hours. PHMSA estimates these changes would save operators $5,235 per year in reporting costs.

New $149,700 Reporting Threshold and Exclusions

PHMSA proposes a $149,700 property-damage threshold for reportable gas and hazardous liquid accidents and clarifies that the threshold excludes specified costs: cost of gas lost (or lost product for liquids), the cost to acquire permits, and the cost to remove and replace non-operator infrastructure not damaged by the release. The rule also adopts an inflation-adjustment procedure with annual updates posted on PHMSA's website and effective on July 1 each year after calendar year 2026.

Less Public Accident Data — Commenter Concern

Some public-interest commenters (Pipeline Safety Trust and Environmental Defense Fund) said narrowing the property-damage definition would reduce the number of accident reports PHMSA receives and weaken the public database used for trend analysis. PHMSA responds that consequential releases remain reportable and that the average release size of incidents that would be exempted is less than four gallons.

No Significant Impact on Small Entities

PHMSA certifies that, if finalized as proposed, the rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act. PHMSA states the change is expected to reduce burdens for operators and not impose new burdens on them.

Possible Small Consumer Price Relief

PHMSA says the estimated operator cost savings from reduced reporting might also lower costs passed on to the public, because pipeline operators generally transfer a portion of compliance costs to their customers.
