  • Geotechnical Aspects of Tailings Dams and Their Failures
    September 4, 2019 | 2:00-3:00 EDT

    Tailings dams and other residuals impoundments fail with significant consequences about 1 to 2 times per year worldwide. Many more failures and near misses occur each year with limited consequences. Mine tailings, coal ash residuals, other waste impoundments and dredged fills where the materials are placed by hydraulic sluicing are potentially liquefiable. If liquefaction occurs, uncontained wastes can flow at rapid rates for long distances and result in massive devastation. This webinar, offered by the Committee on Geological and Geotechnical Engineering of the National Academies of Sciences, Engineering, and Medicine, will review some significant tailings dam failures and failure rates relative to other facilities. Key aspects of geotechnical failures of tailings dams and shear strength concepts for loose granular materials will be reviewed. Dr. Marr will share his own design and monitoring recommendations developed over 45 years of experience with tailings dam design, failure assessments, and study of the work of others.

  • EPA Office of Research and Development's Office of Science Policy Mine and Mineral Processing Virtual Workshop
    October 2, 9, 16, and 23 | 1:00-3:00 pm EDT

    This 4-part virtual workshop series sponsored by EPA's Office of Research and Development will address current challenges at mining and mineral processing sites. The featured topics are Site Characterization, Emergency Management, Innovative Technologies and Strategies, and Big Data.

  • NRDAR: Remediation and Restoration in the Lower Basin of the Coeur d'Alene River
    October 16, 2019 | 12:00-1:00 GMT

    A combination of approaches is being used to facilitate prioritization of cleanup and restoration actions at the Bunker Hill Mining and Metallurgical Complex Superfund site, while engaging project partners. These approaches include: multiple objective decision analysis (MODA) tools, modeling tools, evaluations of innovative remedial technologies, and iterative data collection. MODA techniques were used to engage with the Restoration Partnership and other key stakeholders for input and value identification, and to provide feedback on the sensitivity of project selection criteria and scoring. EPA is combining modeling, iterative data collection aand other tools to manage the initial selection of pilot projects and remedial/restoration design concepts. The importance of dovetailing remediation and restoration, starting with prioritization of projects through design and construction, will be discussed.

Upcoming Meetings

  • Mine Closure 2019
    September 3-5, 2019 | Perth, Australia

    Conference themes will include landform design and rehabilitation, site remediation and impact management, and land rehabilitation and ecosystem restoration.

  • 41st Annual Conference of National Association of Abandoned Mine Land Program (NAAMLP)
    September 8-11, 2019 | Pittsburgh, Pennsylvania

    NAAMLP's annual conference will be conducted jointly with the 2019 Pennsylvania Abandoned Mine Reclamation Conferece and the 47th Annual Conference of the National Association of State Land Reclamationists. These three organizations share common goals and interests focused on successful reclamation and environmental restoration of previously and currently mined sites including the abatement or treatment of mine drainage.

  • CleanUp 2019
    September 8-12, 2019 | Adelaide South Australia

    The International CleanUp Conference has a range of site characterization and remediation themes, including metals and radionuclides contaminants. Several presentations focus on mining sites.

  • 2019 San Juan Mining & Reclamation Conference
    September 24-26, 2019 | Silverton, Colorado

    The goal of this conference is to educate the public and other stakeholders on the science and policy of mining, mine lands remediation, and water quality as it relates to non-point source pollution, improving mining practices, and addressing water quality impairments through workshops, field tours, and presentations.

  • Mine Design, Operations & Closure Conference
    May 3-7, 2020 | Fairmont, Montana

    This conference typically includes sessions on land rehabilitation, reclamation, and remediation. Check back for more information as it becomes available.

 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.
