Abandoned Mineland Acid Mine Drainage (AML AMD) Inventory
An inventory of land and water impacted by past mining (primarily coal mining) is maintained by the Office of Surface Mining Reclamation and Enforcement to provide information needed to implement the Surface Mining Control and Reclamation Act of 1977. The inventory contains information on the location, type, and extent of abandoned mined lands, as well as information on the cost associated with the reclamation of those problems.
