Notes:

This data set includes ferrous metal processing plants in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey, and the operations are those considered active in 2003 and surveyed by the MIT. This is a replacement for the November 1998 map layer. The data is legacy and not expected to be updated. It is being provided as the best available until Mineral Resources identifies an alternative data source.This data set is intended 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 12,000,000-scale data.
