HOMER CITY, Pennsylvania — On Saturday at 7 a.m., Shawn Steffee stood on a hill overlooking the Homer City Generation Power Plant with his family and the community he grew up with. They were all looking at Pennsylvania’s largest coal-fired power plant for the last time — the plant he and his father, uncles, brother, and the union he had guided had all worked at for decades.

Steffee, the business manager for Boilermakers Local No. 154, whose labor force was one of several at the plant, told the Washington Examiner the effect of the plant closure, announced two years ago, would be devastating not just to his union but to the community he grew up in.
