ITRC Environmental Molecular Diagnostics: New Tools for Better Decisions - January 7, 2014, 2:00PM-4:15PM EST (19:00-21:15 GMT). Environmental molecular diagnostics (EMDs) are a group of advanced and emerging analytical techniques used to analyze biological and chemical characteristics of environmental samples. Although EMDs have been used over the past 25 years in various scientific fields, particularly medical research and diagnostic fields, their application to environmental remediation management is relatively new and rapidly developing. The ITRC Environmental Molecular Diagnostics Fact Sheets (EMD-1, 2011), ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013) and this companion Internet-based training will foster the appropriate uses of EMDs and help regulators, consultants, site owners, and other stakeholders to better understand a site and to make decisions based on the results of EMD analyses. At the conclusion of the training, learners will be able to determine when and how to use the ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013); define when EMDs can cost-effectively augment traditional remediation data sets; and describe the utility of various types of EMDs during remediation activities.

ITRC Project Risk Management for Site Remediation - January 14, 2014, 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. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live .

Green Remediation Best Management Practices: Materials and Waste Management (EPA 542-F-13-003). The process of cleaning up a contaminated site often involves purchasing and consuming large volumes of manufactured items as well as raw or processed resources. Site cleanup can also generate significant volumes of waste that could be recycled or salvaged for reuse rather than disposed of at landfills. To help cleanup decision-makers reduce environmental footprints associated with materials and waste, the U.S. Environmental Protection Agency recently issued a new "green remediation BMP" fact sheet on materials and waste management. The best management practices (BMPs) involve various approaches to purchasing greener products and expanding capability for material reuse or recycling rather than disposal (December 2013, 4 pages). View or download at http://clu-in.org/techpubs.htm .

Climate Change Adaptation Technical Fact Sheet: Groundwater Remediation Systems (EPA 542-F-13-004). In February 2013, the U.S. EPA released the draft U.S. Environmental Protection Agency Climate Change Adaptation Plan. The plan examines how EPA programs may be vulnerable to a changing climate and how the Agency can accordingly adapt in order to continue meeting its mission of protecting human health and the environment. EPA's Superfund Program has undertaken associated efforts to identify potential impacts of climate change on site remediation projects and to identify adaptation strategies. A key component of the Superfund climate change adaptation action plan involves developing tools that can help project managers and other cleanup stakeholders to identify, prioritize and implement site-specific measures for increasing remedy resilience to climate change impacts. EPA's new Climate Change Adaptation Technical Fact Sheet: Groundwater Remediation Systems is the first in a series intended to serve as an adaptation planning tool by providing an overview of potential climate change vulnerabilities and presenting possible adaptation measures that may be considered to increase a remedy's resilience to climate change impacts. Concepts addressed in this tool can also apply to site cleanups conducted under other regulatory programs or through voluntary efforts (December 2013, 8 pages). To learn more about climate change adaptation in the Superfund Program, visit www.epa.gov/superfund/climatechange . View or download the fact sheet at http://clu-in.org/techpubs.htm .

Updated Guidance for RCRA Subtitle C Permit Writers and Permittees (EPA 530-R-11-006). EPA has released an update (Version 3, October 29, 2013) to the Resource Conservation and Recovery Act (RCRA) program guidance document entitled Hazardous Waste Treatment, Storage, and Disposal Facilities (TSDF) Regulations: A User-Friendly Reference Document for RCRA Subtitle C Permit Writers and Permittees. The document consolidates and streamlines the TSDF regulatory requirements into a helpful reference tool with a user-friendly format that includes hyperlinked references to the regulations. There are also links to Federal Register notices, flow charts, checklists, and other guidance documents (October 2013, 64 pages). View or download at http://www.epa.gov/osw/hazard/tsd/permit/tsd-regs/tsdf-ref-doc.pdf .

2013 Fall Update of the Regional Screening Levels (RSLs) for Chemical Contaminants at Superfund Sites. The 2013 Fall update to the Regional Screening Levels (RSLs) for Chemical Contaminants at Superfund Sites is complete. The RSLs are a merger of the EPA Region 3 Risk-Based Concentration (RBC) Table, Region 6 Human Health Medium-Specific Screening Levels (HHMSSL) Table and the Region 9 Preliminary Remediation Goals (PRG) Table. Screening levels for every EPA region are available on the RSL website. The RSL tables provide comparison values for residential and commercial/industrial exposures to soil, air, and tapwater (drinking water). The unified use of the RSLs to screen chemicals at Superfund sites promotes national consistency. The update includes risk-based screening levels that were calculated using the latest toxicity values, default exposure assumptions and physical and chemical properties, and a calculator where default parameters can be changed to reflect site-specific risks. View and use at http://www.epa.gov/reg3hwmd/risk/human/rb-concentration_table/ .
