Abandoned mine lands (AMLs) are those lands, waters and surrounding watersheds where extraction, beneficiation or processing of ores and minerals has occurred. AMLs can pose serious threats to human health and the environment. The EPA conducts and supervises investigation and cleanup actions at a variety of mine sites. The Agency has a range of resources related to the environmental risks and challenges present in investigating and cleaning up AMLs. The EPA also pursues opportunities to explore innovative reuse opportunities at mine sites.

Abandoned Mine Lands Spotlight

Best Practices: EPA has issued “Planning for Response Actions at Abandoned Mines with Underground Workings: Best Practices for Preventing Sudden, Uncontrolled Fluid Mining Waste Releases.” EPA developed these best practices to minimize the potential for sudden uncontrolled releases of fluid mine waste resulting from its response actions. 

EPA headquarters and regional offices will use these best practices, as applicable, before carrying out Superfund activities at hardrock-mining and mineral-processing sites with fluid-release hazards.
