EPA Region 9 manages a diverse and challenging portfolio of CERCLA hardrock mine sites. These sites are characterized by human and ecological impacts from legacy mine wastes, often across extensive geographic areas. The design and construction of remedies at mine sites present challenges distinct from other CERCLA sites, including variable waste materials, large volumes, difficult terrain, and the need to integrate engineering solutions with natural landscapes and existing communities. Experience to date highlights the importance of adaptive design, constructability focused planning, and transparent information sharing to support effective and durable mine cleanup outcomes, while underscoring the need to continue learning, advancing, and improving how EPA and the broader cleanup community address the unique demands of these sites.
To advance these objectives, EPA Region 9 and the Society of American Military Engineers (SAME) San Francisco Post are pleased to host the Abandoned Mine Cleanup Information Exchange. This event is intended to provide a collaborative forum where practitioners can share lessons learned, discuss emerging best practices, and explore practical design and construction solutions specific to hardrock abandoned mine cleanup in the western United States.
