The coal-fired power plant is one of Allegheny County's top 10 single sources of air pollution. The company cited higher costs of environmental compliance and "unfavorable economic conditions."
The group says the coal-fired power plant is allowing soot and coal ash to fall on the surrounding community, and isn’t operating its pollution control scrubbers as much as it could be.
Residents and environmental advocates are calling for tough limits on water pollution from a coal-fired power plant situated a few miles upstream from the water intake for the Pittsburgh Water and Sewer Authority.
