Waste oil burning has been banned in WA for at least 30 years. All wood stoves have to have a catalytic converter. When I moved here in 1972, forest wood permits were $5 for five cords and USFS was glad to have you clean up slash piles and around the roads. It is now $40 a cord and you can only cut standing dead trees (no cedar). Plus they have closed all the logging roads since there is no more logging of federal managed land.
I heat with natural gas that runs about $750 a year if it doesn't get below zero very often. I took out the wood stove the year after the air quality people banned wood stoves for 65 days one winter and I had to heat with electricity.
Of course if you are on one of the many Indian Reservations, you are exempt from any of this. Only the EPA can stop oil and wood burning and they have no enforcement branch here. This is why the state is so strict so the smoke doesn't get to bad for the folks in Idaho and Montana.
