This answer is bogus. The burning restrictions they are citing are for OUTDOOR burning. From everything you have said, this wood is being burned inside to generate heat. Right?
If it’s being burned inside - at least in my State - it is illegal to burn pressure treated wood. And in my State, that rule is enforced by our State Dept of Environmental Protection. When they receive a complaint they investigate. Don’t know how they make the determination, but I have seen some news articles where they went to court and got court orders issued to stop burning.
You might check with your State DEP authorities and ask about their rules and regs.
Well actually the regs they are citing are for indoor burning. In Colorado they declare pollution advisory days if the conditions are such that the smoke will stay close to the ground, generally from a thermal inversion.
However, it may be possible that another agency could do something. I’m going to see how he reacts to the letter. I suspect it has already been burned in his fireplace.
Here is a quote from the health dept about the wood burning restrictions:
In response to your concern regarding the neighbor burning treated wood, the easy asnwer is they should not be. Unfortuntately the State Wood Burning Regulations No. 4 really only pertains to the intstallation of EPA certfied wood stoves and burning on red/blue advisory days. While you cannnot use a non-certified wood stove on a pollution advisory day, if you live above 7000ft you are also exempt. As far as burning clean wood- this falls under “Safe Burning Advice” and in not specified as a requirement. At Boulder County Public Health we always tell people they need to burn clean wood, but can’t honestly site where it is a requirement under the woodstove regulation.
