Pipeline Construction Alerts Get Inflation Boost
Published Date: 4/24/2026
Proposed Rule
Summary
PHMSA wants to raise the money limits that trigger pipeline operators to notify them about certain construction and maintenance work on gas and hazardous liquid pipelines. They’re also planning to update how these limits adjust for inflation every year. This affects pipeline operators and aims to keep reporting rules fair and up-to-date, with comments open until June 23, 2026.

Analyzed Economic Effects
6 provisions identified: 5 benefits, 0 costs, 1 mixed.
Annual inflation adjustments to thresholds
Starting after calendar year 2026, PHMSA will update reporting and construction-notification dollar thresholds each year based on price indexes. Updates will be published on PHMSA's website and take effect each July 1 and remain in effect until the following June 30. PHMSA will use the Producer Price Index for construction materials for OPID construction notifications and the CPI for incident reporting as specified.
Higher construction notice dollar line
If you operate natural gas pipeline facilities, PHMSA proposes operators would only need to notify PHMSA before planned construction work that costs $15,000,000 or more (up from $10,000,000). You must give PHMSA at least 60 days' notice unless an emergency makes that impossible.
Higher hazardous-liquid construction cutoff
If you operate hazardous liquid pipeline facilities, PHMSA proposes operators would only need to notify PHMSA before planned construction work that costs $20,000,000 or more (changed from $10,000,000). You must give PHMSA at least 60 days' notice unless an emergency prevents that.
Raise UNGSF maintenance reporting threshold
If you operate underground natural gas storage wells, PHMSA proposes operators would only need to notify PHMSA before maintenance that involves plugging, abandonment, or a workover rig that costs $250,000 or more for an individual well (up from $200,000). You must give PHMSA at least 60 days' notice unless an emergency prevents that.
Fewer notifications and small cost savings
PHMSA estimates the proposed changes would reduce Type F notifications by 117 per year and save about $21,005 annually across operators. PHMSA also says these savings may result in reduced costs to the public if operators pass along lower compliance costs.
No expected safety harm; small-entities finding
PHMSA preliminarily finds the proposed threshold increases would not have adverse effects on pipeline safety and certifies the rule is not expected to have a significant economic impact on a substantial number of small entities.
