Training and Events


  • Slides and audio for the December 7, 2016, webinar Re-Imagining the Future of Mining Sites are now archived for viewing/download on EPA's Clu-In.org website. Webinar presentations explored the broad spectrum of safe and productive reuses possible at mining sites and included a case study highlighting several of these reuses in practice at a mining site in Salt Lake City, Utah. The webinar highlighted how EPA works with mining stakeholders to address the serious health and environmental challenges posed by some mining practices, and how EPA supports the reuse of these areas to benefit the surrounding community.
  • EPA's Office of Superfund Remediation and Technology Innovation's recent webinar on Passive Treatment of Mining-Influenced Water: From Bench Scale to O&M has been archived and is available now. Case study presenters included Jim Gusek, Sovereign Consulting, Inc., Rick Weaver, U.S. Forest Service, Bob Hedin, Hedin Environmental, and Amy Wolfe, Trout Unlimited. The November 14, 2016, webinar was the latest in TIFSD's CLU-IN Webinar Series on Mining.
  • Recordings of select sessions held at the Society of Environmental Toxicology and Chemistry (SETAC) meeting in Salt Lake City, UT (November 2015) are available to view for free at http://slc.setac.org/program/scientific-program/session-recordings/
  • Slides and audio for the NEPA and Mining 101 courses, Part 1 Mining Fundamentals and Part 2 Mining Environmental Concerns and Issues are now archived at https://clu-in.org/conf/tio/NEPAandMining101-2_052416/.

Upcoming Meetings

  • 2017 Society of Mining Engineers Annual Conference & Expo and Colorado Mining Association 119th National Wester Mining Conference
    February 19-22, 2017 | Denver, Colorado

    This conference includes a tract on technologies for managing mining influenced water in historical mine pools.

  • Joint Conference of the West Virginia Mine Drainage Task Force Symposium
    April 9-13, 2017 | Morgantown, West Virginia
    Sponsored by: American Society for Mining and Reclamation (ASMR) &
    Appalachian Regional Reforestation Initiative (ARRI)

    This conference will feature presentations on both active and passive treatment of acid mine drainage, reclamation policy and success, revegation, stream restoration, post-mining land use, and more.

  • Mine Water Solutions in Extreme Environments
    April 10-12, 2017 | Vancouver, Canada

    Organized by InfoMine, Inc., the conference will cover areas like water management in extremely wet areas and extreme dry areas both, water management in extremely cold areas, complex hydrogeological settings and challenging geochemical conditions.

  • 25th Annual Mine Design, Operations & Closure Conference
    May 7-11, 2017 | Fairmont, Montana

    The Mine Design, Operations & Closure Conference will offer the latest in mining-related technologies and methods, delivered by industry professionals. The conference includes a session on remediation and reclamation.

  • 2017 Pennsylvania Abandoned Mine Reclamation Conference
    June 21-22, 2017 | Wilkes Barre, Pennsylvania

    This conference will highlight success stories, challenges, and economic development construction projects dealing with abandoned mine lands. Discussions will be held on the future of abandoned mine reclamation in Pennsylvania and how to address the sunset of the Abandoned Mine Land Trust Fund.

  • 13th International Mine Water Association Congress
    June 25-30, 2017 | Lappeenranta, Finland

    IMWA 2017's Congress theme is "Mine Water & Circular Economy." Circular economy means, "closing the loop" of product lifecycles by improving recycling and re-use. In case of mine water, this means that mining wastes and mine water are used to extract valuable materials, such as metals, fertilizers or adsorbents for waste water purification.

  • National Association of Abandoned Mine Land Programs, 2017 Annual Conference
    September 24-27, 2017 | Lexington, Kentucky

    Information on this conference will be updated, when available.

 CLU-IN Mining Sites Webinar Series

 Workshops on Hardrock Mine Geochemistry and Hydrology

EPA's Region 10, ORD, and OSRTI hosted a three-part workshop series on hardrock mine geochemistry and hydrology in 2013. The goals included enhancing participants' understanding of the key issues regarding water chemistry predictions, identifying potential sources of contamination from mine sites, and describing practices to mitigate or reclaim facilities to protect natural resources. Presenters included experts from EPA Headquarters, Regions, and ORD; the U.S. Geological Survey; and the U.S. Forest Service. The workshops were open to all agencies, tribes, consultants, and the general public, and are now archived and available for streaming. Supplementary materials and resources provided by the instructors are also available for download below.

Workshop 1 - Evaluating Water Chemistry Predictions at Hardrock Mine Sites
