Californians can thank themselves for the tragedy. They voted for politicians and policies for cleaner air, and this fire was the direct result:
https://lao.ca.gov/Publications/Report/3798 Check the statements about the VMP program which was crippled by CARB. The CARB regulations are written in such a way that if you perform burns on safe days, that is banned due to low mixing and the possibilitiy of pollution. OTOH if you burn on a high mixing day that is ok and of course it is also dangerous. So agencies and landowners do nothing to avoid liabilitiy from CARB and related lawsuits.
The fault for this tragedy belongs to CARB and the manhy idiots who support CARB.
Over 90% of the fires in CA consume Federal land.
Not under state regulation. Under federal regulation.
