  • CLU-IN Webinar Series on Mining Sites - OSRTI's Technology Innovation and Field Services Division hosts a quarterly CLU-IN webinar series on that targets EPA Remedial Project Managers and other site staff. Topics include innovative and ecological approaches to dealing with mining waste, reuse and recovery technologies, and other related focus areas. The webinars are listed below under Upcoming Internet Seminars. Archives of past webinars can be found under Archived Internet Seminars, Videos, and Courses.
  • Region 10 Workshops on Hardrock Mine Geochemistry and Hydrology – In February and March 2013, EPA's Region 10, Office of Research and Development (ORD), and OSRTI hosted a three-part webinar series that focused on evaluating the potential for contaminant release from hardrock mine sites. Topics included water chemistry, potential sources of contamination from mine sites, and mitigation and reclamation practices to protect natural resources. The webinar archives and related resources can be accessed below through Workshops on Hardrock Mine Geochemistry and Hydrology or downloaded (1pg, 222KB).

Upcoming Internet Seminars

  • Mining Waste Treatment Technology Selection Webinar
    March 24, 2016 | 1:00PM - 3:15PM EDT
    Sponsor: Interstate Technology and Regulatory Council

    Mining produces millions of tons of waste each year. Contaminants from unreclaimed or unremediated areas have affected millions of acres of land and over 10,000 miles of stream. Historical mining practices and the absence of routine mined-land reclamation, remediation, and restoration have led to legacy sites with significant environmental and human health impacts. New mining operations continue to have severe waste issues that must be addressed during and after the actual mining operation. Conventional remedial solutions are often lengthy, expensive, and unacceptable to the regulated and regulatory communities, as well as to the public.

  • Biochemical Reactors for Treating Mining Influenced Water
    March 31, 2016 | 1:00PM - 3:15PM EDT
    Sponsor: Interstate Technology and Regulatory Council

    Mining influenced water (MIW) includes aqueous wastes generated by ore extraction and processing, as well as mine drainage and tailings runoff. MIW handling, storage, and disposal is a major environmental problem in mining districts throughout the U.S and around the world. Biochemical reactors (BCRs) are engineered treatment systems that use an organic substrate to drive microbial and chemical reactions to reduce concentrations of metals, acidity, and sulfate in MIWs. The ITRC Biochemical Reactors for Mining-Influenced Water technology guidance (BCR-1, 2013) and this associated Internet-based training provide an in-depth examination of BCRs; a decision framework to assess the applicability of BCRs; details on testing, designing, constructing and monitoring BCRs; and real world BCR case studies with diverse site conditions and chemical mixtures.

  • NAAMLP 38th Annual Conference
    September 26-28, 2016 | Bozeman, Montana

    The National Association of Abandoned Mine Land Programs (NAAMLP) is a non-profit organization whose members include 31 states and tribes conducting abandoned mine reclamation programs under the federal Surface Mining Control and Reclamation Act of 1977. The theme of their 38th Annual Conference is "Enhancing Communities through Reclamation." Stay tuned for more information on the 2016 conference offerings.

  • 201 National Tribal Mining Workshop
    October 2016 | Location TBD

    As a follow-up to the October 2015 101 Mining and National Environmental Policy Act (NEPA) Workshop, the EPA Alliance Training Group along with participants of the Natioal Tribal Mining Workgroup (NTMW) and keynote speakers will deliver a 201 National Tribal Mining Workshop that is dynamic, customized and an engaging training session for attendees.

    The 201 workshop training topics will cover the NEPA, effective comments, TEK, tribal engagement, environmental challenges, groundwater, air and waste compliance issues related to mining activities on tribal lands, mining operations in general and any other topics requested by the NTMW. A detailed agenda will be release this spring.

 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.
