Reporting Pipeline Emergencies and Vapor Emissions

If you discover a pipeline on your property or notice unusual vapor emissions, it is critical to act quickly to ensure your safety and the safety of your community. While many pipelines are safely managed, unidentified or leaking infrastructure requires immediate attention from the correct authorities.

1. Immediate Safety Actions

If you smell a "rotten egg" odor, see a white cloud/mist, or hear a hissing sound:

• Evacuate immediately: Leave the area on foot in an upwind direction.
• Avoid sparks: Do not use cell phones, light matches, or switch on lights/appliances near the area.
• Call 911: Once you are at a safe distance, notify local emergency services.

2. Identify the Pipeline Owner

Most pipelines in the U.S. are marked by signs at road crossings, railways, and intersections. These markers typically include:  

• The name of the pipeline operator.
• The product being transported.
• An emergency contact number.

3. Contact Federal and State Regulators

If you cannot identify the owner or if local agencies are unable to assist with a persistent issue, you should reach out to the following organizations:

• PHMSA (Pipeline and Hazardous Materials Safety Administration):This federal agency oversees the safety of the nation's pipeline infrastructure. You can report a safety concern directly through their oversight programs.   

• State Pipeline Safety Agencies:Each state has a department (often under a Public Utilities Commission) that handles intrastate pipeline issues.   

• National Association of State Fire Marshals (NASFM): NASFM provides resources and specialized training for responding to pipeline emergencies and can be a valuable resource for understanding local safety protocols.

4. Use "811" for Location Services

If you are unsure of what is under your home or property, call 811 (the national "Call Before You Dig" number). While primarily for excavation, they can help identify registered utility lines on your property.
