SAN FRANCISCO (AP) — The California agency investigating a deadly pipeline explosion and the City of San Bruno are set to propose major fines they say Pacific Gas & Electric Co. should pay for its negligence leading up to the blast. The City of San Bruno says the utility's shareholders should pay no less than $1.25 billion for violations regulators say PG&E committed before the 2010 explosion. City officials say that would let survivors know the California Public Utilities Commission is serious about preventing another pipeline disaster. The San Bruno blast killed eight people and destroyed 38 homes. Commission investigators and consumer advocates will also file their own fine proposals Monday, and PG&E will file its proposal later this month. A CPUC judge is expected to make a final decision about how much to fine PG&E later this year.
