The BP refinery in Whatcom County has resumed producing gasoline for customers, although it has still not completely recovered from a fire in February, a source close to the refinery said Wednesday.

The Cherry Point refinery is Washington state's largest, and normally is able to convert 225,000 barrels of crude oil a day into gasoline, diesel and jet fuel. Each barrel of crude oil produces approximately 19 gallons of gasoline, according to the U.S. Energy Information Administration, meaning Cherry Point under normal operation would refine approximately 4.3 million gallons of motor fuel daily.

Scott Dean, a spokesman for BP, said the company "still expects to be restarting the refinery over the month of May."

Production was halted on February 17, when a fire in the central crude distillation unit shut down the refinery.

The refinery has some units running now, but that there are "too many variables at play" to provide an estimate of when the refinery will be completely on-line, said the person close to the refinery operation.
