The Office of the State Fire Marshal (SFM) regulates the safety of approximately 5,500 miles of intrastate hazardous liquid transportation pipelines and acts as an agent of the federal Office of Pipeline Safety concerning the inspection of more than 2,000 miles of interstate pipelines. Pipeline Safety staff inspect, test, and investigate to ensure compliance with all federal and state pipeline safety laws and regulations. All spills, ruptures, fires, or similar incidents are responded to immediately; all such accidents are investigated for cause.

Hazardous liquid pipelines are also periodically tested for integrity using procedures approved by SFM. The program has been certified by the federal government since 1981. The SFM also maintains Geographic Information Systems (GIS)-based maps of all regulated pipelines and has been named as a state repository for pipeline data by the National Pipeline Mapping System (NPMS).
