Pipeline Safety Guidance Gets Crystal Clear—Nothing Shocking
Published Date: 4/24/2026
Rule
Summary
This update helps pipeline operators better understand and follow safety rules for hazardous liquid pipelines, especially near sensitive areas. It clears up confusing parts of the guidance so pipelines stay safer and operators know exactly what to do. The new rules kick in on August 3, 2026, and could save money by preventing costly accidents.
Analyzed Economic Effects
4 provisions identified: 4 benefits, 0 costs, 0 mixed.
Keeps Appendix C Voluntary
The rule clarifies Appendix C to 49 CFR part 195 is non-binding guidance and does not become mandatory if an operator incorporates parts of it into their Integrity Management (IM) program. You (pipeline operators) can adapt or modify elements of Appendix C for your IM plan provided you still meet the minimum requirements in Part 195.
Drainage-Tile Consideration Limited
PHMSA clarifies that the recommended consideration of agricultural drainage tiles when deciding if a pipeline crossing a farm could affect a High-Consequence Area (HCA) should be based on information and knowledge available to the operator. This change may reduce the need for additional surveys of drainage tiles and lower costs for hazardous liquid pipeline operators.
Moves Factors Into Threat Identification
The rule relocates guidance on physical support of the pipeline, maximum operating pressure exceedances, and natural force damage (earth movement/seismicity) from the section on identifying segments that could affect HCAs into the guidance on identifying threats to pipeline integrity. Operators should now consider those items as risk/threat factors when planning assessments.
PHMSA: Minimal Cost Savings, No Big Burden
PHMSA states this direct final rule will reduce regulatory uncertainty and result in minimal cost savings for pipeline operators, and certifies it will not have a significant economic impact on a substantial number of small entities. PHMSA also finds the rule will not have adverse safety effects.

2026-08144 — Administrative Rulemaking, Guidance, and Enforcement Procedures
The Department of Transportation is bringing back and improving the rules about how it makes new regulations, issues guidance, and enforces laws. This affects anyone involved in transportation safety and compliance, updating how decisions are reviewed and enforced. These changes kick in on May 27, 2026, aiming to make the process clearer and more efficient without adding new costs.
2026-09392 — Hazardous Materials: Notice of Applications for New Special Permits
The Department of Transportation is reviewing new special permit requests for safely moving hazardous materials, like damaged lithium-ion batteries. If you work with these materials, now’s your chance to comment before June 11, 2026. These permits could change how some dangerous goods are transported, making things safer and possibly saving money on special packaging rules.
2026-09304 — Pipeline Safety: Meeting of the Gas Pipeline Advisory Committee
The Gas Pipeline Advisory Committee is meeting on May 28, 2026, to talk about new safety rules for gas pipelines that affect pipeline companies and the public. They’ll review proposed changes aimed at making gas distribution safer, and everyone can join in person or online. If you want to share your thoughts, you have until June 29, 2026, to send in comments—this could impact how pipelines operate and keep communities safer.
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.
