In the midst of another soot seige, the question arises: What does "clean burning" in your fireplace mean? And can you do it even when the local air district bans burning for the day?
The short answer: No, you can't burn any kind of wood, pellets or manufactured logs, such as Duraflame, when the San Joaquin Valley Air Pollution Control District prohibits burning your county.
Clean burning applies only to days when burning is allowed. And it isn't a requirement. It's a suggestion from the air district.
The authorities would prefer it if you used a federally certified wood-burning stove or similar device. The U.S. Environmental Protection Agency says manufactured logs burn cleaner.
If you check the air district's page today, you'll see burning is banned throughout the eight counties on the Valley floor.
There are exceptions. If you don't have access to natural gas or if you have no other way to heat your home except wood burning, you qualify for an exception.
