This section examines how TRI chemical wastes are managed in the metal mining sector.
This map shows the locations of the metal mining facilities (defined as facilities reporting their primary NAICS code as 2122) that reported to TRI for 2018. Click on a facility for details on its TRI reporting. Mines are shown on this map based on their longitude/latitude, which may be miles from the city identified on the mine’s TRI reporting forms. Mines can qualify their location relative to the city by noting the distance in the street address data field of their TRI reporting forms.
Metal Mines Reporting to TRI, 2018
View Larger Map
For 2018, 86 metal mining facilities reported to TRI. They tend to be in western states where most of the copper, silver, and gold mining occurs; however, zinc and lead mining tend to occur in Missouri and Tennessee, as well as Alaska. Metals generated from U.S. mining operations are used in a wide range of products, including automobiles, electric and industrial equipment, jewelry, and decorative objects. The extraction and processing of these minerals generate large amounts of on-site land disposals, primarily of metals included on the TRI list of chemicals contained in the ore and waste rock. To learn more about metal mining operations and their TRI reporting, explore the interactive metal mining diagram. Metal mining operations are subject to federal and state regulations .
