Pacific Gas and Electric will be appealing a $1.4 billion penalty proposed by the California Public Utilities Commission involving a deadly explosion in 2010.  

The pipeline blast in San Bruno killed eight people and destroyed a number of homes.  

The utility said in a statement today it will ask the commission to review the administrative law judges' recommendation to ensure a final decision takes into consideration what PG&E has done to promote safety.  

The company adds that any penalty should benefit public safety.
