EPA announced that it is adding 12 sites Superfund National Priorities List (NPL) and is proposing to add another five. These are sites where releases of contamination pose significant human health and environmental risks. Cleaning up contaminated sites is important for the health, safety, and revitalization of communities. Thousands of contaminated sites, from landfills, processing plants, to manufacturing facilities exist nationally due to hazardous waste being dumped, left out in the open, or otherwise improperly managed. President Biden's Bipartisan Infrastructure Law will accelerate EPA's work to help communities clean up these contaminated sites with a $3.5 billion investment in the Superfund Remedial Program and reinstates the Superfund chemical excise taxes, making it one of the largest investments in American history to address legacy pollution. This historic investment strengthens EPA's ability to tackle threats to human health and the environment, and EPA has already set action in motion to clear the backlog of the 49 contaminated sites which had been awaiting funding to start remedial action.
