Pipeline Valves Get Extra Breather Time—90 Days of Chill
Published Date: 4/24/2026
Proposed Rule
Summary
PHMSA wants to give pipeline operators more time—90 days instead of 14—to get rupture-mitigation valves (RMVs) working on gas, liquid, and CO2 pipelines. This change helps companies manage safety tech better without rushing, affecting pipeline operators nationwide. Comments on this proposal are open until June 23, 2026, and it could impact how quickly safety upgrades happen and possibly costs.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 0 costs, 1 mixed.
RMV Deadline Extended to 90 Days
PHMSA proposes to change the required time to make rupture-mitigation valves (RMVs) or equivalent tech operational from 14 days to 90 days after placing the new or replaced pipeline segment into service. This applies to new or entirely replaced onshore gas transmission, hazardous liquid, and CO2 pipeline segments 6 inches or larger that affect high-consequence areas (or are in Class 3 or 4 locations) and were installed after April 10, 2023; Class 1 or 2 segments with a potential impact radius of 150 feet or less are excluded.
Estimated Annual Cost Savings ($20,877)
PHMSA estimates the proposed change will produce cost savings of $20,877 per year for the regulated community and expects some of those savings may be passed along to the public. PHMSA preliminarily determined the rule will not have adverse safety effects.
Big Drop in Extension Notifications (90%)
PHMSA proposes increasing the operability deadline to 90 days, which it expects will yield a 90 percent decrease in the number of requests operators submit to extend the operational deadline. PHMSA lists the current estimated annual responses as 435 and estimated annual burden hours as 2,215 for the information collection.
Notification and Extension Procedures Updated
Under the proposal, operators must notify PHMSA if an RMV cannot be made operational within 90 days of installation, and operators must notify PHMSA if a valve cannot be repaired or replaced within 12 months. Operators choosing alternative equivalent technology must notify PHMSA at least 90 days in advance and may request extensions or exemptions if compliance is economically, technically, or operationally infeasible.

2026-08673 — Pipeline Safety: Adjustment to OPID Notifications for Construction; Correction
The Department of Transportation fixed a mistake in a recent rule about when gas pipeline companies must notify the government about construction costs. They’re raising the cost limits for reporting from $10 million to $20 million and from $200,000 to $300,000 to keep up with inflation. This change affects pipeline operators and helps make sure the rules match what was originally intended, starting May 5, 2026.
2026-08064 — Pipeline Safety: Removing Obsolete Provision From Safety-Related Condition Reporting Requirements for Hazardous Liquid and Carbon Dioxide Pipeline Facilities
Starting August 3, 2026, pipeline operators must stop sending safety reports by fax and switch to email only. This change affects companies handling hazardous liquid and carbon dioxide pipelines and speeds up how quickly safety info gets to the right people. No extra costs here—just a smoother, faster way to keep pipelines safe!
2026-08067 — Pipeline Safety: Removing Unnecessary Provision for Material Properties Verification During MAOP Reconfirmation
PHMSA is making pipeline safety rules simpler by removing a needless step that required testing certain pipe materials during pressure checks. This change helps gas pipeline operators save time and money without cutting corners on safety. Comments on this proposal are open until June 23, 2026, so stakeholders have a chance to weigh in.
