In the Bay Area here in California, we have the California Air Resources Board. They decide when to issue "Spare the Air" alerts due to levels of particulates and pollution in the air. Right now when they declare a "Spare the Air" day, there is no burning of wood fireplaces, pellet stoves or any outdoor fires. It is a $400 citation for a second offense. They actually have guys that drive around documenting complaints. Currently, it does not apply to charcoal BBQ's but I predict that within 5 years they will be included. I self police right now, electing to use my gas Q whenever a "Spare the Air" alert is issued. I got tired of not being able to use my wood burning stove during winter because of the numerous alerts. Had it taken out and replaced with a new gas insert. It actually heats the house better, is on a thermostat and is cheaper than buying a cord of wood. Get use to it if you live in a populated area.
