This data set portrays the approximate location of 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. NBII-SAIN (ed.) created this file by clipping USGS abnminx020.shp. to the southern and eastern states. NBII-SAIN website: (http://sain.nbii.gov/).
The geographical information in the Abandoned Mines Land
Inventory System (AMLIS) is a point representing each
Problem Area. For many Problem Areas the point is the
latitude and longitude of the southeast corner of the USGS
quadrangle in which the Problem Area is located. For
others it is the center of the Problem Area. For the latest
information on Problems Areas, see the AMLIS system at:

This is the contact information for the parent dataset (abnminx020.shp) used to create this file.
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. The data should
be displayed and analyzed at scales appropriate for
1:2,000,000-scale data. No responsibility is assumed by
the U.S. Geological Survey in the use of these data.
Metadata imported. This data was "clipped" to the southern and eastern states with ESRI ArcMap 8.2.
Dataset copied.
No consistent horizontal accuracy checks have been made.
In recent years the computer system use to store and
manipulate the data, AMLIS, performs a check to see that
the latitude and longitude data entered into the system
are in the correct county. Data entered before this check
was added may be in the wrong county. Also, a problem
may be in one county and the southeast corner of the
quadrangle containing the problem in another county.
Problem Areas shown as polygons were digitized from
hand-drawn maps. The boundary of a Problem Area is often
a judgment call made by the AML Reclamation Specialist
preparing the map.
Not all coal related problems are included in the inventory. In most cases, States and Indian tribes are responsible for finding problems and entering them into the Abandoned Mine Land (AML) Inventory. Some have chosen not to inventory all their problems, especially if they have a great many problems already in the inventory. Also, not all damage to lands and water by past coal mining qualifies for inclusion in the inventory. To be included as high priority, problems must pose a threat to human health, safety, or welfare. NBII-SAIN (ed.) created this file by clipping from the merged boundaries of three TN counties (Hamilton, Marion, and Sequatchie), two AL counties (Dekalb and Jackson), and three GA counties (Dade, Walker, and Catoosa) using USGS abnminx020.shp.

No tests for logical consistency were performed on this data set.
None. Acknowledgment of the U.S. Office of Surface Mining
and (or) the National Atlas of the United States of America
would be appreciated in products derived from these data.
Although these data have been processed successfully on a computer
system at the U.S. Geological Survey, no warranty expressed or

of the data on any other system, nor shall the act of distribution
constitute any such warranty.
