Drones and Satellites Patrol Pipelines: PHMSA Goes High-Tech
Published Date: 4/24/2026
Proposed Rule
Summary
PHMSA is updating pipeline patrol rules to officially allow cool tech like drones and satellites for checking gas and hazardous liquid pipelines. This means pipeline operators can use new remote sensing tools instead of just walking or driving, making inspections smarter and possibly faster. If you’re involved in pipeline safety, get ready to comment by June 23, 2026, and maybe save some time and money with these tech upgrades!
Analyzed Economic Effects
5 provisions identified: 3 benefits, 1 costs, 1 mixed.
Drones and Satellites Allowed for Patrols
PHMSA proposes to clarify that pipeline right-of-way patrol methods are technology neutral: operators may observe or image ROWs using walking, driving, manned or unmanned aerial systems (UAS/drones), satellite, or other appropriate means under 49 CFR 192.705(c) and 195.412(a). This change formally permits using drones and satellites to satisfy patrol requirements.
Estimated $26.2M Annual Cost Savings
PHMSA preliminarily estimates the proposed rule will produce annualized cost savings of $26.2 million by reducing regulatory burdens and uncertainty for gas, hazardous liquid, and carbon dioxide pipeline operators. PHMSA also expects these savings may reduce costs passed on to the public.
Imagery Must Be 'Current' and Comparable
PHMSA proposes to require that aerial or satellite imaging used for patrols provide 'current' information and imaging quality comparable to traditional aerial patrols so they are equivalent for observing right-of-way surface conditions. Operators remain responsible for selecting tools and ensuring they meet patrol performance expectations.
Patrol Frequency Requirements Remain
PHMSA is not changing patrol frequencies: under 49 CFR 192.705 gas transmission pipelines must be patrolled between one and four times each calendar year (depending on class location and crossings), and under 49 CFR 195.412 hazardous liquid and CO2 pipelines must be inspected at least 26 times each calendar year (about every 3 weeks).
No Significant Impact on Small Entities
PHMSA certifies under the Regulatory Flexibility Act that the proposed rule is expected to reduce regulatory burdens and, if finalized as proposed, will not have a significant economic impact on a substantial number of small entities.

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.

Previous: 2026-08079 — Pipeline Safety: Property Damage Definition for Reporting Incidents on Gas Pipelines and Accidents on Hazardous Liquid and Carbon Dioxide Pipelines
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.
Next: 2026-08081 — Pipeline Safety: Adjust Annual Report Deadlines
Pipeline operators who manage gas pipelines and storage facilities will get more time to file their annual reports and update pipeline maps. The new deadline moves from March 15 to June 15, making it easier to meet reporting requirements without rushing. This change helps keep things organized and on schedule, with no extra costs involved.
