Happy Day-After-Earth Day, Wisconsin - - Where Earth Day Was Founded.Says The Daily Reporter, via AP:
Wisconsin’s largest business group says Gov. Scott Walker has signed a bill that would give wastewater plants, paper mills and food processors up to 20 years to comply with the state’s phosphorus limits...
Wisconsin Manufacturers and Commerce released a statement Wednesday saying Walker has signed the bill.History from 2010, when Wisconsin government still had environmental values based on a long legacy, and an all-parties-at-the-table collaborative ethic.
And then the Walkerites took control and turned over Wisconsin environmental policy-making to the WMC.
