BLAINE, Wash. (AP) — BP says it’s working to meet customer demand as its Cherry Point refinery in Washington state remains idle following a fire.

Company spokesman Scott Dean says it’s still too early to say what caused the fire or how long it will be before the plant resumes operations. In the meantime, he says, BP is working to satisfy customer demand from existing stocks at Cherry Point as well as from other sources.
