Pipeline Safety Division

In 1981, the California Legislature established the Hazardous Liquid Pipeline Safety Act with the intent that the Office of the State Fire Marshal (OSFM) shall exercise exclusive safety regulatory and enforcement authority over intrastate hazardous liquid pipelines. The Office of the State Fire Marshal currently regulates the safety of approximately 6,500 miles of intrastate hazardous liquid transportation pipelines. The Pipeline Safety Division consists of engineers, analytical staff, and clerical support located in northern, central and southern California. Pipeline Safety staff inspect pipeline operators to ensure compliance with federal and state pipeline safety laws and regulations. The Division is also responsible for the investigation of pipeline ruptures, fires, or accidents for cause and determination of probable violations.

State Law requires Pipeline Operators to notify the Office of the State Fire Marshal, Pipeline Safety Division of certain activities or changes in operations. Starting December 2018, pipeline operators may send certain required notifications or requests to OSFM by email to PipelineNotification@fire.ca.gov. All notifications and requests must be on a company letterhead. Examples of common notifications and requests include:

  • Ownership Change
  • Change of Service
  • Hydrostatic Testing Notification
  • In-Line (ILI) Inspection Waiver Requests
  • Construction Notification
  • Deferred Maintenance Requests (see ADB 2016-05)

Requests and notifications sent to OSFM via email fulfil State notification requirements only and do not meet requirements for reporting to or notification of the Department of Transportation, Pipeline and Hazardous Material Safety Administration (PHMSA).

For questions regarding electronic notifications, please contact the Pipeline Safety Division at PipelineNotification@fire.ca.gov or by phone at (562) 497-9100.

Potential for Damage to Pipeline Facilities Caused by Flooding, River Scour, and River Channel Migration - PHMSA is issuing this advisory bulletin to remind all owners and operators of gas and hazardous liquid pipelines of the potential for damage to pipeline facilities caused by severe flooding and actions that operators should consider taking to ensure the integrity of pipelines in the event of flooding, river scour, and river channel migration. [Docket No. PHMSA-2019-0047].


Senate Bill 295, (Jackson, Chapter 607, Statute of 2015) mandates the Office of the State Fire Marshal (OSFM) to adopt regulations and conduct annual inspections of each intrastate hazardous liquid pipeline to reduce the potential pipeline accidents in California and protect the environment. Effective February 9, 2017, the proposed regulations implementing the OSFM annual pipeline inspections were adopted and incorporated in the California Code of Regulations (CCR), Title 19, Division 1, Chapter 14, Hazardous Liquid Pipeline Safety. See below for more information on these regulations and the documents incorporated by reference.

The May 19, 2015 pipeline incident at Refugio Beach in Santa Barbara County spilled over 100,000 gallons of crude oil and impacted over 25 miles of coastline and ocean water. The impacts from the spill were devastating, both environmentally and economically. The Office of the State Fire Marshal conducted three public workshops to discuss draft proposed regulations requiring the use of best available technology on new, replacement, or retrofit of pipelines near environmentally and ecologically sensitive areas in the coastal zone (Title 5, California Government Code 51013.1). Click here for more information on the workshop: Title 19 Regulations Development.

On January 5, 2016, the Pipeline Safety Division held an informational meeting for the pipeline industry. This meeting was to inform Hazardous Liquid Pipeline Operators in California of two significant pipeline safety bills (SB 295 and AB 864) that were recently signed into law. Changes to out-of-service pipeline designation were also discussed.
