The 1977 Surface Mining Control and Reclamation Act requires coal companies to clean up damage as they mine.

The reclamation process for all surface mining—including coal, bentonite, and trona—is very similar. When mining begins, the top soil—the top layer of fertile soil in which plants grow—is removed and saved for later use. The overburden—the soil that covers the mineral—is also removed and saved. Once mining operations are finished ...
