Our action against illegal polluters led to historic victory.

When it comes to polluters breaking our cornerstone environmental laws or regulators who aren’t taking the proper steps to make sure polluters comply with these laws, PennEnvironment has long worked to use the power of citizen enforcement actions under the Clean Water Act and Clean Air Act to address these issues. In 2016, PennEnvironment litigated a federal Clean Air Act lawsuit against the largest steel company in the world, ArcelorMittal, after uncovering hundreds of environmental violations at the company's coal processing facility located just outside of Pittsburgh in the city of Monessen, PA.  A settlement is now in sight that will require the company to upgrade the facility, reduce its pollution, pay a significant civil penalty, and comply at last with the Clean Air Act.
