Pipeline Documents

The CPUC audits natural gas transmission and distribution pipeline safety, work place safety, and reliability of gas delivery to consumers.  The CPUC also investigates reports of gas leaks or other safety concerns.

On September 9, 2010, a PG&E natural gas transmission pipeline exploded in San Bruno California.  The CPUC joined with the National Transportation Safety Board (NTSB) to investigate the incident.  Exhibits relating to this initial investigation can be found at the NTSB docket site.

For more information about the CPUC’s own investigation into the San Bruno incident and proceedings arising from that investigation, see our page on Information on Natural Gas Pipeline Safety.

 

Audits

 

The CPUC conducts regular audits of the natural gas transmission and distribution functions for each utility providing natural gas in the state.  The CPUC also audits mobile home parks that provide distribution of natural gas and/or propane to its residents.

 

The CPUC compares the functions of transmission and distribution with the requirements set out by General Order 112E as well as federal standards set forth in US Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA).
