State Sen. Nancy Skinner, a Democrat representing Berkeley, said the proposal is about saving money for consumers.
“While global crude prices are not something we can control, a shortage of refined gasoline is something that we can prepare for,” she said.
Newsom unveiled the legislation in August, during the last week of the regular legislative session. But lawmakers in the state Assembly said they needed more time to consider it. The governor called the Legislature into a special session to try to pass it.
The bill needs final approval by the state Assembly before it can reach Newsom’s desk.
It has received intense pushback from Republican lawmakers, labor groups and the oil industry. Some opponents say it could unintentionally raise overall gas prices and threaten the safety of workers by giving the state more oversight over refinery maintenance schedules. They argued delaying necessary maintenance could lead to accidents.
The Western States Petroleum Association criticized Newsom and the Democratic lawmakers supporting the bill, saying it would not benefit consumers.
“If they were serious about affordability, they’d be working with our industry on real solutions,” Catherine Reheis-Boyd, the group’s president, said in a statement. “Instead, they’re forcing a system they don’t understand, and Californians will pay the price.”
Californians pay the highest rates at the pump due to taxes and environmental regulations. The average price for regular unleaded gas in the state is about $4.67 per gallon as of Friday, compared to the national average of $3.21, according to AAA.
