After doing this for a living 30 years, these are the first proposed EPA regulations I have looked after 10 years of retirement.
All I needed to see is that the EPA has now promulagated NSPS to the level of Subpart OOOO. That means there are now approaching near 100 specific process specific standards for new equipment and operation. Honestly, without looking it up, I'd have a hard time thinking of 100 industries that emit VOC's.
I always felt even back then, that if EPA wanted to eliminate our and their jobs, they could enact standards and enforcement parameters that would force industry overseas. One way to do it, is to force plants to invoke leakless technology on every single flange, valve, pump, and compressor. Even down to the 1/4 inch size.
Plants already have to self report air violations under Title V, so add the possibility of upping the fines 10X per occurence...... It will be no problem at all for the EPA to Biden's dirty work in forcing industries out of the U.S.
