Free EPA Webinars

Posted By Darrell Smith, Tuesday, March 1, 2016
EPA’s Technology Innovation and Field Services Division is offering several free webinars that may be of interest to IMA-NA members, including the following.

Ecological Revitalization and Contaminated Sites - March 17, 2016, 2:00PM-3:30PM EDT (18:00-19:30 GMT). Restoring local ecosystems as part of the cleanup and reuse of contaminated properties can enhance remedies, strengthen community interest and provide significant environmental benefits. These native landscapes improve soil health and support diverse vegetation, protect air and water quality, support wildlife habitat and recreation areas, and enable environmental education opportunities. This webinar focuses on ecological revitalization and provides an in-depth look at the TVA Kingston Fossil Plant Fly Ash site in Kingston, Tennessee. Restoration efforts there went beyond cleanup requirements, with native species supporting diverse natural habitats. 

ITRC Mining Waste Treatment Technology Selection - March 24, 2016, 1:00PM-3:15PM EDT (17:00-19:15 GMT). ITRC's Mining Waste Team developed the ITRC Web-based Mining Waste Technology Selection site to assist project managers in selecting an applicable technology, or suite of technologies, which can be used to remediate mine waste contaminated sites. Decision trees, through a series of questions, guide users to a set of treatment technologies that may be applicable to that particular site situation. Each technology is described, along with a summary of the applicability, advantages, limitations, performance, stakeholder and regulatory considerations, and lessons learned. Each technology overview links to case studies where the technology has been implemented. In this associated Internet-based training, instructors provide background information then take participants through the decision tree using example sites. Project managers, regulators, site owners, and community stakeholders should attend this training class to learn how to use the ITRC Web-based Mining Waste Technology Selection site to identify appropriate technologies, address all impacted media, access case studies, and understand potential regulatory constraints.

ITRC Biochemical Reactors for Treating Mining Influenced Water - March 31, 2016, 1:00PM-3:15PM EDT (17:00-19:15 GMT). 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. At the end of this training, you should be able to complete the following activities: describe a BCR and how it works; identify when a BCR is applicable to a site; use the ITRC guidance for decision-making by applying the decision framework; improve site decision-making through understanding of BCR advantages, limitations, reasonable expectations, regulatory and other challenges; and navigate the ITRC Biochemical Reactors for Mining-Influenced Water technology guidance (BCR-1, 2013).
