Inland Empire gas prices approaching $4 a gallon

The average price of a gallon of self-serve regular gasoline in the Inland Empire today recorded its largest daily increase since Feb. 24, 5.6 cents, because of a Northern California refinery fire expected to reduce gasoline supplies.
The average price of $3.975 is the highest in Riverside and San Bernardino counties since June 16, according to figures from the AAA and Oil Price Information Service.
The average price is 15.6 cents more than one week ago, 30.4 cents higher than one month ago and 22.1 cents greater than one year ago.
The average price has risen 28 times in the past 29 days, increasing 32 cents over that span, including 4.6 cents on Thursday.
“Monday night’s major fire at the Chevron refinery in Richmond had an immediate effect on the wholesale gasoline market on Tuesday, which caused gas prices to shoot up since then,” said Jeffrey Spring of the Automobile Club of Southern California.
“Southern Californians have already been experiencing increased pump prices for nearly a month due to higher oil prices and this incident has just made the increases come even more quickly.
“However, since that Northern California refinery is still partly operating, the impact may not be as great as what happened in February with the Cherry Point refinery fine in Washington. More should be known in the next few days.”
The fire at a BP refinery in Washington state in February left the plant out of commission until May, causing gasoline prices in the Pacific Northwest to rise about 70 cents.
