While watching the local TV coverage of the horrible Clairton Coke Works explosion, I noticed that the hillside across the river from the Clairton plant is covered with vegetation. I was surprised. While I was growing up in the Mon Valley that hillside was bare. Nothing would grow on it because of the air pollution. I don’t know when the vegetation started coming back, but I’m glad. Apparently their air pollution controls are working. This is very good news.
