Parts per BILLION...barely at detectable levels. So what would be the consequences of having say 72 parts per billion rather than 68 parts per billion? The difference between these levels are well within measuring error. Billions in higher costs for what possible benefit?
Anyone who was alive before the late 70s knows what real smog was like. In most of the US, we don’t have anything resembling smog. Even in the places we do, it is usually caused by local conditions, mountain valleys, etc.
It’s really frustrating to live in an ozone hotbed because it comes off Lake Michigan from naturally occurring processes certain times of the year.
Back when factories belched smoke and cars had no emissions controls, there was significant benefit to these rules, but tightening them at this point has no real benefit.
We’ll be paying billions to make reductions within the level of sampling error.
...and we take 5 parts per billion out while China is belching thousands of times that every day.
This is the problem with measuring technology. We’re at zero.
Actually...my ozone analyzers reliably measure down to single digit ppbs. Once we start talking ppts...that is a different subject.
Those benefits would be to the parasites that work for these government agencies.
“Billions in higher costs for what possible benefit?”
Havent you heard? It, um, empowers the people...and stuff.
