People in LA need to breathe during the summer time. So yes we demand a blend that protects our residents. And the refiners are choosing to close refineries. They are not being compelled.

They are being strangled, it’s their choice to tap out is how I would put it.

The improvement in air quality is due to the clean air act, catalytic converters, and the shuttering of industry, the gas blend plays a minor part. Even then, with gas so much higher it will materially make peoples lives worse, at some point society would be better off getting rid of the blend.

Yeah, I remember flying into LAX in the late 80s and early 90s. Smog so thick it looked like a physical obstacle.

Whatever they're doing seems to be working nicely.
