ITRC Project Risk Management for Site Remediation - December 11, 2012, 2:00PM-4:15PM EST (19:00-21:15 GMT). Remediation Risk Management (RRM) is a course of action through which all risks related to the remediation processes (site investigations, remedy selection, execution, and completion) are holistically addressed in order to maximize the certainty in the cleanup process to protect human health and the environment. Remediation decisions to achieve such a goal should be made based on threshold criteria on human health and ecological risks, while considering all the other potential project risks. Through this training course and associated ITRC Technical and Regulatory Guidance Document: Project Risk Management for Site Remediation (RRM-1, 2011), the ITRC RRM team presents tools and processes that can help the site remediation practitioner anticipate, plan for, and mitigate many of the most common obstacles to a successful site remediation project. Examples of project risks include remediation technology feasibility risks; remedy selection risks; remedy construction, operation and monitoring risks; remedy performance and operations risks; environmental impacts of systems during their operation; worker safety risk, human health and ecological impacts due to remedy operation; as well as costs and schedules risks including funding and contracting issues.

In Situ Treatment of Soil Metals: Science to Experience - December 12 and 19, 2012, 2:00PM-4:00PM EST (19:00-21:00 GMT). This is a two-part webinar series. The information presented in these webinars is based on a forum discussion led by EPA Headquarters and Region 9 on alternative approaches to reducing human and ecological exposures to soil contaminants. Technical experts will deliver presentations on topics including: using on-site treatment, candidate contaminants of concern (COCs), soil amendments, metals bioavailability, mining and other metals sites, exposure reduction, revegetation and erosion control. For more information and to register, see http://clu-in.org/live .

ITRC Biofuels: Release Prevention, Environmental Behavior, and Remediation - December 13, 2012, 11:00AM-1:15PM EST (16:00-18:15 GMT). This training, which is based on the ITRC's Biofuels: Release Prevention, Environmental Behavior, and Remediation (Biofuels-1, 2011), focuses on the differences between biofuels and conventional fuels specific to release scenarios, environmental impacts, characterization, and remediation. The trainers will define the scope of the potential environmental challenges by introducing biofuel fundamentals, regulatory status, and future usage projections. Participants will learn how and when to use the ITRC biofuels guidance document for their projects. They will understand the differences in biofuel and petroleum behavior; become familiar with the biofuel supply chain, potential release scenarios and release prevention; be able to develop an appropriate conceptual model for the investigation and remediation of biofuels; and select appropriate investigation and remediation strategies.

New CLU-IN Focus Area on Solidification. Solidification/Stabilization (S/S) refers to a general category of processes used to treat a wide variety of wastes, including solids and liquids. In general solidification encapsulates a waste to form a solid material to restrict contaminant migration by decreasing the surface area exposed to leaching, while stabilization involves chemical reactions that reduce the leachability of a waste through a chemical reaction. The application can be performed in situ or ex situ. S/S is commonly used on inorganic wastes; however, it has been successfully applied at manufactured gas plants to reduce leaching of polycyclic aromatic hydrocarbons found in coal tars. View and use at http://clu-in.org/solidification .

New CLU-IN Focus Area on In Situ Chemical Reduction. In situ chemical reduction involves the placement of a reductant or reductant generating material in the subsurface for the purpose of degrading toxic organic compounds to potentially nontoxic or less toxic compounds, immobilizing metals such as chromium VI by adsorption or precipitation, and degrading non-metallic oxyanions such as nitrate. Commonly used reductants are zero valent iron (ZVI), ferrous iron, sodium dithionite, sulfide salts (calcium polysulfide), and hydrogen sulfide. The introduction of substrates to microbially produce reducing conditions favorable to microbial reduction of iron and sulfates also has been used to treat dissolved metal contamination.

Brownfields Grant Recipients' Road Map to Understanding Quality Assurance Project Plans (EPA 542-R-12-005). The U.S. EPA prepared this publication to help recipients of an EPA Brownfields Assessment Grant design and complete site assessment projects more efficiently and effectively by increasing their awareness and understanding of the importance of quality assurance (QA) in Brownfields site projects. The Road Map describes a general process for developing and using a Quality Assurance Project Plan (QAPP), while highlighting the benefits of a well-prepared QAPP and helping those responsible for the process to better understand and communicate with all parties involved (November 2012, 20 pages).

Green Remediation Best Management Practices: Implementing In Situ Thermal Technologies (EPA 542-F-12-029). Over recent years, the use of in situ thermal technologies such as electrical resistance heating, thermal conductive heating, and steam enhanced extraction to remediate contaminated sites has notably increased. The U.S. EPA's latest (13th) green remediation "BMP fact sheet" describes processes, equipment, and analytical tools that can be used to reduce the environmental footprint of applying these technologies, which typically involves significant energy consumption. The best management practices (BMPs) address other core elements of a greener cleanup: reducing air pollutants and greenhouse gas emissions, reducing water use and negative impacts on water resources, improving materials management and waste reduction efforts, and protecting ecosystem services. The BMPS may be used during design, construction, operation and maintenance, and/or monitoring of an in situ thermal project (October 2012, 6 pages).

Technology News and Trends (EPA 542-N-12-005). This issue highlights in situ thermal (IST) technologies such as electrical resistance heating (ERH), steam enhanced extraction, and thermal conduction heating. These technologies have been used more often over recent years, primarily to remove non-aqueous phase liquid in contaminant source areas. Since fiscal year (FY) 2005, IST technology has been selected for use at 18 Superfund sites in addition to numerous RCRA corrective actions, brownfield sites, or military installations needing accelerated cleanup of highly defined source areas (October 2012).
