Tallahassee, Fla. — A bill being considered by the Florida Legislature would lower the severance tax the phosphate industry pays for rock mined in the state. Mosaic spokesman Russell Schweiss said the current rate included a surcharge that was requested by the industry to cover costs associated with the closing of processing plants formerly owned by Mulberry Phosphates, which declared bankruptcy and abandoned the facilities several years ago. The clean-up program that followed was paid for by the severance tax, which was raised at that time. The change would essentially end the surcharge.
