EPA Solicits Public Comments on Action Plan for RE-Powering America's Land. The U.S. EPA is seeking public comments on the draft action plan for its RE-Powering America's Land Initiative. The plan guides EPA's efforts over the next two years to encourage renewable energy development on current and formerly contaminated lands, landfills and mine sites when such development is aligned with the communitys vision for the site. The cleanup of contaminated land and the production of renewable energy will provide long-term improvements to air quality in communities, while protecting public health. In 2010, the RE-Powering America's Land Initiative published its first management plan to provide a useful framework to engage stakeholders on the potential to site renewable energy on contaminated lands and track progress. This second action plan, Action Plan 2.0, identifies activities planned for the next two years. The agency will solicit comments for 30 days. Comments on the proposed plan are due by Friday, May 30. To submit a comment, please send to cleanenergy@epa.gov. A copy of the draft Action Plan 2.0 is available at http://www.epa.gov/oswercpa/action_plan.htm .

Soil Amendment Applications and Mine Site Restoration Impacts on Soil Ecosystem Services - May 7, 2014, 1:00PM-3:00PM EDT (17:00-19:00 GMT). The next webinar in our CLU-IN mining webinar series will address topics in soil remediation and restoration. Presenters will discuss their research on the use of soil amendments, the impact of soil restoration at mine sites on ecosystem function and services, and deliberate decision-making in site restoration that benefits the whole ecosystem. Dr. Sally Brown will discuss how using residuals led to the development of new soil at a Jasper County, MO Superfund site. Her research team amended mine tailings at the site in the late 1990s and completed sampling in 2012. Dr. Brown will discuss the successful use of residuals at the site, as well as the ecological and economic values of using residuals even when replacement topsoil is readily available. The significance of considering the final fate of the site using a life cycle assessment will also be discussed. Andrew Trlica will present his research that measured soil carbon storage in former surface mines under long-term reclamation. He compared areas reclaimed with biosolids-based soil amendments with areas reclaimed using conventional approaches. This study went on to use a life cycle assessment approach to examine the relative greenhouse gas balance and other ecosystem effects of different land reclamation strategies (for example, restoring a site to a low density residential use in comparison with restoring to a forest).

ITRC Soil Sampling and Decision Making Using Incremental Sampling Methodology Parts 1 and 2 - May 13 and 15, 2014. This 2-part training course along with ITRC's web-based Incremental Sampling Methodology Technical and Regulatory Guidance Document (ISM-1, 2012) is intended to assist regulators and practitioners with understanding the fundamental concepts of soil/contaminant heterogeneity, representative sampling, sampling/laboratory error and how ISM addresses these concepts. Through this training course you should learn: basic principles to improve soil sampling results, systematic planning steps important to ISM, how to determine ISM Decision Units (DU), the answers to common questions about ISM sampling design and data analysis, methods to collect and analyze ISM soil samples, the impact of laboratory processing on soil samples, and how to evaluate ISM data and make decisions. In addition this ISM training and guidance provides insight on when and how to apply ISM at a contaminated site, and will aid in developing or reviewing project documents incorporating ISM (e.g., work plans, sampling plans, reports).

ITRC Mining Waste Treatment Technology Selection - May 20, 2014, 2:00PM-4:15PM EDT (18:00-20:15 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. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live .

ITRC Biochemical Reactors for Treating Mining Influenced Water - May 22, 2014, 11:00AM-1:15PM EDT (15:00-17:15 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).

Checklist: How to Address Changing Climate Concerns in an Analysis of Brownfield Cleanup Alternatives (ABCA) (EPA 560-Q-14-001). Our climate is changing and we need to adapt to make sure brownfield cleanups are still protective of human health and the environment now and into the future. To ensure that brownfield cleanups remain effective as the climate changes EPA has added a new term and condition to its cooperative agreements, starting with the FY13 Cleanup and Revolving Loan Fund (RLF) Grants, that requires recipients to "evaluate the resilience of the remedial options in light of reasonably foreseeable changing climate conditions (e.g., sea level rise, increased frequency and intensity of flooding and/or extreme weather events, etc.)." EPA has created an Analysis of Brownfield Cleanup Alternatives (ABCA) checklist to help these Cleanup and RLF grant recipients meet this new term and condition.

Sedimentary, My Dear Watson. Passive Sampling Methods and Sediment Remediation (Podcast). The management of contaminated sediment is often expensive and time-consuming, involving millions of dollars over many years at a single site. However, an easier solution may be coming to a regulatory agency near you. Passive sampling methods offer several advantages over traditional remediation and monitoring techniques, and are the focus of this podcast episode (12 minutes).
