This training on the ITRC Technical and Regulatory Guidance for Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) describes the transition (the bridge) between aggressive remedial actions and MNA and vise versa. Enhanced attenuation (EA) is the application of technologies that minimize energy input and are sustainable in order to reduce contaminant loading and/or increase the attenuation capacity of a contaminated plume to progress sites towards established remedial objectives. Contaminant loading and attenuation capacity are fundamental to sound decisions for remediation of groundwater contamination. This training explains how a decision framework which, when followed, allows for a smooth transition between more aggressive remedial technologies to sustainable remedial alternatives and eventually to Monitored Natural Attenuation. This training will demonstrate how this decision framework allows regulators and practitioners to integrate Enhanced Attenuation into the remedial decision process.

Green Remediation: Opening the Door to Field Use Session A (Introduction and Carbon Calculus: A RCRA Case Study) - November 24 1:00PM-3:00PM EST (18:00-20:00 GMT). In July, EPA held its annual National Association of Remedial Project Managers meeting in Portland, OR and one of our most attended sessions was on Green Remediation (GR). Because of its success, members of EPA's Technical Support Project, led by the Engineering Forum, have taken this full-day session and are bringing back a number of the same talks as online seminars this fall and winter. There will be three sessions, each 1.5 hours long. EPA's definition of GR includes the practice of considering the environmental effects of a remediation strategy (i.e., the remedy selected and the implementation approach) early in the process, and incorporating options to maximize the net environmental benefit of the cleanup action. Some practices are quite "mature," such as construction site best management practices including stormwater runoff management and construction and demolition (C&D) debris recycling. Others are still emerging, including the use of renewable energy sources such as wind and solar to power remedial systems. Over the three sessions, the online training will introduce you to the key technical, policy, and application aspects of GR. For more information and to register, see http://ciu-in.ora/studio . ITRC Performance-based Environmental Management - December 2, 2:00PM-4:15PM EST (19:00-21:15 GMT). Performance-based environmental management (PBEM) is a strategic, goal-oriented methodology that is implemented through effective planning and decision logic to reach a desired end state of site cleanup. The goal of PBEM is to be protective of human health and the environment while efficiently implementing appropriate streamlined cleanup processes. This ITRC training presents an overview of what PBEM is, explains how and when to implement it, and describes the issues that regulators are concerned about throughout PBEM's implementation. Case studies will be presented to illustrate successful PBEM projects. The course is valuable not only because PBEM is being proposed and implemented at TechDirect: November 1, 2008 2 of 6 clu-in.ora/newsletters ------- many federal and private sites throughout the country, but also because PBEM provides an opportunity to enhance all site remediation.

Then select the appropriate month and year for the updates in which you are interested. The following reports were featured on EUGRIS: Environment Agency (England and Wales) United Kingdom Ecological Risk Assessment for Contaminants in Soils (2008). The ERA framework provides a structured approach for assessing the risks to ecology from chemical contamination in soils (a requirement under Part 2A (Contaminated Land) of the Environmental Protection Act 1990). The framework consists of a three-tiered risk assessment process: Tier 1 of the risk assessment is a screening step based on a comparison of chemical analyses of site soils with a soil screening value (SSV) for the contaminants of potential concern; Tier 2 uses a choice of tools (ecological surveys and biological testing) to gather evidence for any harm to ecological receptors (plant and animal species) present at the site; Tier 3 seeks to attribute the harm to the chemical contamination.
