History of Pennsylvania's AML Inventory

DEP and the Federal Office of Surface Mining (OSM) both maintain separate abandoned mine land (AML) inventories. The two datasets share many commonalities, but there are also many differences because they were developed based of different criteria and to serve different purposes. The federal inventory also includes data for all states and Indian Tribes that participate in the AML program.
