Pipeline mapping

Pipeline Safety Division - Pipeline GIS/Mapping

The State Pipeline Mapping System is a Geographic Information System (GIS), housed in the Office of the State Fire Marshal’s (SFM) Pipeline Safety Division. In 1995, Assembly Member Kuehl introduced AB 592, which was later signed by Governor Pete Wilson and codified as Sections 51017 to 51017.2 of the California Government Code. The law requires the California State Fire Marshal to create a comprehensive Geographic Information System (GIS) database of pipeline information for the specific intent of emergency response.


Pipeline Mapping - Standards

The standards for the State Pipeline Mapping System reflect those of the National Repository standards. There are three small deviations between the systems. The state system is requiring both age and diameter attributes. The state system has a positional accuracy standard goal of + 100 feet rather than the national + 500 feet. Finally, the state system is NOT requiring natural gas lines or liquefied natural gas facilities.

The Office of the State Fire Marshal’s Pipeline Mapping Standards will reflect those of PHMSA’s National Pipeline Mapping Standards and describe in detail the age data standards.
