The Orange County average price is 59.2 cents more than one week ago, $1.23 higher than one month ago, and $2.044 greater than one year ago.
The rising prices are the result of insufficient supply to meet demand caused in part by reduced production of gasoline from refineries undergoing maintenance, Marie Montgomery, a public relations specialist with the Automobile Club of Southern California, told City News Service.

Checks could be rolled out as early as Friday.
