Over 90% of the fires in CA consume Federal land.
Not under state regulation. Under federal regulation.
That's true. But that's also due to lack of fire management due to California's regulations, see Rule 4106: https://www.valleyair.org/rules/currntrules/r4106.pdf:
Land Manager: any federal, state, local or private entity that administers, directs, oversees or controls the use of public or private land, including the application of fire to the land.
4.9.2 For a multi-day burn which may impact smoke sensitive areas, a land manager or his or her designee shall coordinate daily with the District or the ARB to affirm that the burn project remains within the conditions specified in the smoke management plan, or whether contingency plans must be implemented.
So despite the principle of federal preemption, the fact is that California is preventing proper wildfire management by controlled burns.
Take a good long look at the policies that the Sierra Club pushed thru with Bruce Babbitt in office with Bill Clinton.
