ABSTRACT
The AML (Abandoned Mine Land) Inventory is a collection of areas where surface features of abandoned mines are present. Presently the data is shown using three layers. AML Inventory Sites is used to show the entire boundary of a problem area. AML Points and AML Polygons are used to show specific problems within a designated inventory site. The inventory Does Not Include complete and comprehensive coverage of abandoned underground mines, surface or underground mines that were permitted and closed after 1982, or active surface or underground mines. For further information concerning mining in your area, please contact the local DEP office. This data set portrays the approximate location of Abandoned Mine Land Problem Areas containing public health, safety, and public welfare problems created by past coal mining. It is a subset of data contained in the Office of Surface Mining (OSM) Abandoned Mine Land Inventory. This layer represents the AML Inventory Sites, which are the boundary of an entire problem area. All related AML point/polygon features must fit within the boundary of the designated problem area. This data set provides information needed to implement Title IV Abandoned Mine Reclamation, of the Surface Mining Control and Reclamation Act (SMCRA) of 1977. One of the major uses of this data set is for the reporting of annual Abandoned Mine Land Program accomplishments to Congress. In addition, the data is used in the National Atlas of the United States for geographic display and analysis at the national level, and for large regional areas.
