They aren't wrong, but somewhere between "absolutely zero particulate emissions" and the current occasional "Spare the air" day ought to have some amount of wiggle room. I do understand where they are coming from in that for the last few years the Bay Area air quality has been, on average "crappy" to use the technical phrase, so the air pollution rules do need to be tightened, but that gets harder and harder to do if things like restaurants and home barbecues get a free pass as they are a larger and larger fraction of the remaining PM2.5, VOC, and NOX sources. Yes, that will kill even more restaurants, or raise the cost of dining out or both.
The Central Valley isn't exactly a bastion of clean air all by itself either, as I have been reminded of over the last few days when we had 100+AQI wind coming our way from the Central Valley.
If it is not one thing it is another.
@Carl_NH FWIW: I can recommend a heat pump dryer. We went from 5kW/hr to 0.5-0.7kW/hr in about the same dry time, with clothes more uniformly dry.
All the best, Peter
