AML Site Information

Abandoned Mine Lands Sites

Monticello Mill Tailings (USDOE) (UT)

This section presents information about abandoned hardrock mines and mineral processing sites listed in the Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS). This includes sites on the National Priorities List (NPL), often referred to as "Superfund" Sites. The Agency also takes emergency response actions at many abandoned mine sites that are not listed on the NPL; these sites are included in the Non-NPL section.
