A state-funded abandoned mine lands reclamation program for Ohio was realized with the establishment of the Unreclaimed Lands Fund in 1972. A state severance tax is imposed on active strip and surface mine operators who extract coal and industrial minerals respectively. This state severance tax provides approximately $1.0 million annually to the Unreclaimed Lands Fund to alleviate the adverse environmental effects of past mining.
