Wisconsin legislators have recently proposed to get rid of protections against toxic air pollutants in Wisconsin.

While some hazardous pollution is regulated by the US EPA at the federal level, they would remove any limits on air pollutants protected by the Wisconsin DNR alone.

To see some examples of the pollution that would go unregulated if the politicians have their way, check out this map using data reported through the Wisconsin DNR, and the U.S. EPA Toxics Release Inventory (TRI) Program.


Through the Toxics Release Inventory, EPA “tracks the management of toxic chemicals that may pose a threat to human health and the environment.” All of the toxic pollution shown here is currently regulated by the Wisconsin DNR, but not at the federal level. This means it would all be without limits going forward if the recent proposal to rollback protections goes through.
