The EPA estimated that it will cost polluting industries $7.6 billion to $8.8 billion a year to meet the 75-ppb standard, but that rule will yield $2 billion to $19 billion in health benefits.

$2B to $19B. That's some nice estimatin' there EPA
Even northern New Hampshire has a number of 70. I bet 60 is a dream. It looks like it has never been reached, anywhere; the dotted line is the previous "limit" of 84. Looks like there is a lot of play around that word "limit". It doesn't appear to mean what we think it does anyway.
I remember the shitty air we had in Philly summers in the late 80s. It is definitely better now.
