I received this e mail today and i have an Oil Boiler in my home, so I was concerned about it.
i researched it at EPA, and found this page
The initial mail says 'all small boilers using oil, boimass, and coal'.... the EPA site specifically excludes residential 1-4 family buildings from the rule and further says boilers over 1.6 million BTU only.
I consider myself somewhat more up to date on this kind of thing, and yet I was almost ready to buy into the conference and recording mentioned in the mail. EPA doesn't have a way for me to report this,at least not one I can find.
I don't know if anyone on this service has encountered this or not, but it may be worth knowing and letting your customers know about it.
That would be a pretty large house to use 1.6 million BTU/hour. Or a very large hot tub!
As for webex / conferences on the compliance... EPA generally offers free classes that you can sign up for that cover such areas. No need for the training - unless you want the certificate for a record of any continuing education requirements that you might need.
