Your Role in Green Remediation Implementation and Case Studies in Green Remediation - This Year's Models and Tools (The 2010 NARPM Green Remediation Session Follow-on Webinars) - January 11 and February 10. In May 2010, EPA held its annual National Association of Remedial Project Managers (NARPM) meeting in Crystal City, VA, and for the third year in a row, one of our most attended sessions was on Green Remediation (GR). And like last year, we are offering those talks again to an online audience! 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. We've got more case studies and maturing policy and guidance that we'd like to share with an online audience. EPA's Technical Support Project, led by the Engineering Forum, has taken this full-day session and split it into three separate sessions that started in December. Each session is scheduled for two hours and will include policy and case studies, with time for Q&A along the way. For more information and to register for the two remaining sessions, see

ITRC Use and Measurement of Mass Flux and Mass Discharge - January 13, 2011, 11:00AM-1:15PM EST (16:00-18:15 GMT).

Contaminated Sediments: New Tools and Approaches for in-situ Remediation - Session III - January 19, 2011, 2:00PM-4:00PM EST (19:00-21:00 GMT). This seminar will feature SRP grantees Dr. Richard G. Luthy and Dr. Charles A. Menzie. Dr. Luthy of the Woods Institute for the Environment at Stanford University will review recent experimental studies and modeling work that describe the up-take of hydrophobic organic contaminants by activated carbon amendment in sediment. The emphasis will be on practical aspects of testing and modeling to assess the suitability of sediment for in-place treatment of persistent organic contaminants by activated carbon sorbent. A comparison of different feeding traits of benthic organisms illustrates the degree of treatment needed to achieve a desired remedial success of sorbent amendment. Recent work with polysulfide rubber-modified activated carbon suggesting the potential to treat both mercury and hydrophobic organic compounds will also be presented. A follow-up by Dr. Charles Menzie of Exponent Inc. will discuss the efficacy of various methods of application of SediMite, a pelletized agglomerate that consists of activated carbon, to contaminated sediments. He will focus on the effectiveness of delivery methods designed to minimally disturb sediment, yet deliver activated carbon amendment to the depth inhabited by biota.

ITRC Use of Risk Assessment in Management of Contaminated Sites - January 25, 2011, 2:00PM-4:15PM EST (19:00-21:15 GMT). This training course identifies how various risk-based approaches and criteria are applied throughout the processes of screening, characterization, and management of contaminated sites. The training course and associated overview document, Use of Risk Assessment in Management of Contaminated Sites (RISK-2, 2008), are intended for risk assessors and project managers involved with the characterization, remediation, and/or re-use of sites. The training and overview document provide a valuable tool for federal and state regulatory agencies to demonstrate how site data collection, risk assessment, and risk management may be better integrated. For more information and to register, see or .

ITRC Phytotechnologies - January 27, 2011, 11:00AM-1:15PM EST (16:00-18:15 GMT). This training familiarizes participants with ITRC's Phytotechnology Technical and Regulatory Guidance and Decision Trees, Revised (Phyto-3, 2009). This document provides guidance for regulators who evaluate and make informed decisions on phytotechnology work plans and practitioners who have to evaluate any number of remedial alternatives at a given site. This document updates and replaces Phytoremediation Decision Tree (Phyto-1, 1999) and Phytotechnology Technical and Regulatory Guidance Document (Phyto-2, 2001). It has merged the concepts of both documents into a single document. This guidance includes new, and more importantly, practical information on the process and protocol for selecting and applying various phytotechnologies as remedial alternatives.

Best Management Practices: Use of Systematic Project Planning Under a Triad Approach for Site Assessment and Cleanup (EPA 542-F-10-010). This technical publication is intended for environmental practitioners engaged in the investigation, design, remediation, and closure or reuse of contaminated sites. Systematic Project Planning is a rigorous project planning process that lays a scientifically defensible foundation for proposed project activities. The bulletin discusses important considerations and contingencies that need to be addressed, and key activities to be performed during SPP at hazardous-waste sites. It guides the reader to think about SPP from early assessment, to evolving to a mature conceptual site model, to looking ahead at site re-use; and emphasizes up-front effort. Included are references where the reader can find tools and more detailed technical guidance (September 2010, 19 pages). View or download at .

Technology News and Trends (EPA 542-N-10-006). This issue highlights pilot-scale and demonstration projects to characterize and remediate sites with fractured bedrock contaminated by volatile organic compounds. Technologies applied in these projects involve subsurface injection of reactive amendments, in situ thermal conductive heating systems, and a range of geophysical tools to interpret a site's existing or emplaced network of hydraulic fractures (December 2010, 6 pages).

Draft Integrated Cleanup Initiative Implementation Plan. The U.S. EPA is releasing for comment the draft Integrated Cleanup Initiative (ICI) Plan, a three-year strategy to focus on the agency's land cleanup programs. Sites covered under the cleanup programs include Superfund, federal facilities, brownfields, Resource Conservation and Recovery Act corrective action, and underground storage tank. The goal of the initiative is to accelerate cleanups of contaminated sites where possible, address a greater number of contaminated sites, and put the sites back into productive use while protecting human health and the environment. The initiative also seeks to provide communities with greater accountability and transparency on EPA's land cleanup programs. While many actions identified in the ICI are underway, EPA will use the comments received to further evaluate and refine the draft plan. EPA's draft plan will be available for public comment through January 10, 2011 (December 2010, 28 pages). View or download at .

Interim Final Guidance, Institutional Controls: A Guide to Planning, Implementing, Maintaining, and Enforcing Institutional Controls at Contaminated Sites.
