Contra Costa Health noted in a news release that as of 11:00 a.m. Sunday, the fire was mostly out, but the agency will keep its health advisory in place for people with respiratory sensitivity until the fire is completely extinguished.
A shelter-in-place alert was declared late Saturday afternoon for specific neighborhoods near the refinery and lifted about 9:00 p.m.
Contra Costa Health said it was first notified of the event when the Martinez Refining Co., owned by PBF Energy, reported the fire through the county's Community Warning System, or CWS, just before 2:00 p.m. Saturday.
