OT - I lived in Pittsburgh when the air was cleaned up. It was done by exposing the US steel industry to foreign competition. This lead to closing most - if not all of the big old steel mills. Before that the industry and the unions joined to oppose every effort at cleaning up the mills.

JDN - Re: ": I have no idea, but when I was a young man they burnt bituminous (soft) coal which was pretty smokey."

The number of operating steel mills in the Pittsburgh area reached close to zero a few years.

So, the reason it was cleaner was the lack of the steel mills and their smokestacks.
