As I consider Gov. Steve Bullock’s new energy plan, a “Blueprint for Montana’s Energy Future,” I’m brought back to another place and another time.I grew up along the banks of the Monongahela River in Glassport, Pennsylvania, about 8 meandering miles before “the Mon” joins with the Allegheny River to create the Ohio River in downtown Pittsburgh. My parents were steelworkers and my earliest memories are of picking up tarry pebbles alongside an oily river. The river ran black, with no signs of life.
