A new rule requires Mon Valley polluters to ease up on dirty air pollution days. Will it work?
The air quality in the Mon Valley should start to get a little better on the very worst days. That’s thanks to a new rule by the Allegheny County Health Department. The rule was passed last year but it took months to get U.S. Steel, the largest polluter in the region, to come up with a plan that would work. The rule has already gone into effect several times this year.
