That doesn't follow. It only follows that they are bad everywhere with circumstances similar to California. A place differing in distribution of population, distribution of agricultural land, weather patterns, and/or water flows might be able to have refineries without causing the harms that makes them difficult to place in California.
The state is large, diverse and already contains vast chunks of unpopulated land. Almost everywhere that isn't near the poles is similar to some part of California.
So, no combustion-based private or public transportation, no detergents, no aspirin, paracetamol or ibuprofen.
It would still be possible to drive an EV, though. You could keep it lubricated with whale oil.
