I was talking to an Uber driver a few months ago about that - he was a pipefitter there and I know someone from my grade school days who's a clerical worker there. The pipefitter told me it was a surprise but he was retirement eligible this year. I knew people who worked at Chevron.
PBF also owns the former XOM refinery in Torrance. As progressive as the Bay Area is, the refineries in Contra Costa County are still there. Chevron in Richmond and Shell in Martinez provides the jet fuel for SFO via pipeline I believe. Golden Eagle was deadly when Tosco ran it - I remember as a kid a PR stunt that they did by sending the refinery ERP team and a regular employee to each school in west and central Contra Costa and handing out rulers after a presentation. It's in Tesoro/Marathon's hands now and nothing major has happened.
I remember meeting an old HS friend randomly and found that he was working as a chemical engineer at Chevron Richmond. That's not just a refinery but a major fuel/lubricant additive development center. And as far as Richmond goes, the Point Richmond area was always considered one of the best, most desirable places to live in Richmond. I also remember as a kid I'd been to the Chevron rod & gun club many times as a class trip. An employee had to sponsor school groups. It was pretty easy for a single elementary school class in the sixth grade, but we ended up going there in junior high and even as junior/senior in HS.
Pacific Refining is gone and I can't even tell where it used to be even though it was next to i-80. But the Phillips 66 refinery is still there and possibly the most visible.
A neighbor of mine works for county hazardous waste. His name sometimes ends up in the news because he's the one who has to talk to reporters when there are refinery incidents. I asked him if he needs to respond to them at any time, and he said he'd even been recalled from vacation.
