ITRC Life Cycle Cost Analysis (RPO-2). This document was produced by the Interstate Technology and Regulatory Council. This overview introduces the reader to the basic concepts of Life-Cycle Cost Analysis. The ITRC Remediation Process Optimization (RPO) Team identified the need for detailed information on Life-Cycle Cost Analysis. This overview will further develop the concepts of life-cycle cost and its potential application to site remediation projects (March 2006, 18 pages). View or download at http://www.itrcweb.org/Documents/RPO-2.pdf .

ITRC Exit Strategy– Seeing the Forest Beyond the Trees (RPO-3). This document was produced by the Interstate Technology and Regulatory Council. This overview reviews the concept and advantages of Performance-Based Exit Strategies as one element of performance-based management (PBM) of environmental remediation projects. The RPO team identified the need for information on several additional PBM topics. This overview focuses on the role of the exit strategy in PBM of site remediation; reviews key elements of an exit strategy, discusses the benefits of preparing a transparent, flexible performance-based exit strategy, summarizes potential obstacles to developing, refining, and implementing a performance-based exit strategy, and considers the role of regulatory agencies in optimizing exit strategies (March 2006, 18 pages). View or download at http://www.itrcweb.org/Documents/RPO-3.pdf .

ITRC Above Ground Treatment Technologies (RPO-4). This document was produced by the Interstate Technology and Regulatory Council. This overview introduces the reader to the basic concepts of optimization of above ground technologies. It provides a general overview of some common optimization opportunities found for above ground treatment systems for (1) extracted ground water, (2) air sparging/soil vapor extraction (AS/SVE), and (3) multi-phase extraction (MPE). Although there are many areas in which optimization can be applied, this overview will focus only on these three. It should also be noted that the discussion of extracted ground water is not intended to advocate pump and treat systems, but rather is an acknowledgment that these systems are in existence and are likely candidates for optimization (March 2006, 26 pages).

ITRC Data Management, Analysis, and Visualization Techniques (RPO-5). This document was produced by the Interstate Technology and Regulatory Council. It introduces the reader to the basic concepts of Data Management, Analysis and Visualization Techniques (DMAVT). Data Management, Analysis, and Visualization Techniques in some ways are important tools in successfully measuring the progress of a remediation or a monitoring program. This overview will further develop the basic concepts of DMAVT and their potential application to site rehabilitation projects (March 2006, 22 pages). View or download at http://www.itrcweb.org/Documents/RPO-5.pdf .

ITRC Performance-Based Management (RPO-6). This overview introduces the reader to the basic concepts of Performance-based Management (PBM). It further develops the basic concepts of PBM and its potential application to site remediation projects. In addition, because the ITRC RPO Team is currently developing a Technical Regulatory Guidance Document on PBM, this articulation represents only a beginning of information on this subject (March 2006, 22 pages).

The Impact of EU Directives on the Management of Contaminated Land - Report of the NICOLE Workshop, Cagliari, Italy, December 2005. This report provides an executive summary of the discussions held during this NICOLE Workshop. The workshop was initiated to: inform and explain to the participants of the workshop what a range of existing and proposed EC Directives might mean to the management of contaminated land; and create an opportunity for dialogue between stakeholders and regulators. The workshop dicussions focused on the EU Groundwater Directive, the Soil Framework Directive, and the Waste Framework Directive (March 2006, 57 pages).

CLU-IN Issue Areas. A new Issue Area feature has been added to CLU-IN. EPA understands that site owners and other parties involved in remedial activities need information on emerging issues. CLU-IN Issue Areas bundle available information associated with selected topics. They draw upon existing resources from the CLU-IN Web site, but also from other sources of information that were not previously cited or available on CLU-IN. These topics are still being researched, and these issue areas will be updated with information from federal cleanup programs, state sources, universities, nonprofit organizations, peer-reviewed publications, and public-private partnerships. We welcome any suggestions you may have for new topics or additional resources. Currently the Issue Areas include sections on DNAPLs, Mining sites, Nanotechnology, Sediments, Vapor Intrusion and Wood Treater sites. For more information, see http://clu-in.org/issues/ .

New Triad Project Profiles. Triad project profiles contain information about completed and ongoing applications of the Triad at contaminated sites. Triad project profiles describe sites that use the elements of the Triad: systematic planning, real-time monitoring and measurement technologies, and dynamic work strategies. While the focus of the profiles is on sites that demonstrated all three components of the Triad, some of these sites exhibited only one or two aspects but are still useful examples. The Triad project profiles provide a summary of relevant site information, contaminants and media, project goals and outcomes, cost and time-savings, detailed information on the Triad work performed at the site, as well as points of contact and electronic references. Five new profiles have been recently added. For more information, see http://www.triadcentral.org/user/profile/index.cfm .

Conferences and Symposia

Long-Term Monitoring Optimization (LTMO) Training (Spring 2006). EPA is partnering with the U.S. Army Corps of Engineers and several state offices to offer training on LTMO for groundwater in Trenton, New Jersey on May 3-4, 2006 and Kansas City, Kansas on June 13-14, 2006. The training provides information about new quantitative methods of LTMO for groundwater. Responsible parties have used LTMO techniques at more than 50 sites nationwide and are likely to use them at more sites in the future. It is important for regulators to be familiar with LTMO techniques. Regulators can use these methods to make appropriate decisions about the optimal location and frequency of groundwater monitoring and about approving changes to groundwater monitoring networks. The training includes information about some of these methods, such as the Monitoring and Remediation Optimization System (MAROS), the Geostatistical Temporal-Spatial algorithm or GTS, and the three-tiered monitoring network optimization (MNO) approach. While the training is designed primarily for state and federal regulators, federal facilities cleanup managers, potentially responsible parties (PRPs), and contractors are welcome to participate. State and federal regulators will receive registration priority. Hands-on training in the use of MAROS will also be provided. For dates and details about each training and to register, visit http://www.trainex.org.

National Sustainable Design Expo and Competition, Washington DC, May 9-10. More than 350 college and university students will be on the National Mall competing for EPA's Second Annual P3 (People, Prosperity, Planet) Award. This EPA showcase features novel designs for green buildings, innovative alternative fuel technologies, ideas on rainwater collection, and even options for "greening" the apparel industry. It is an opportunity to see cutting-edge technologies developed by university students and their faculty advisors; learn what nonprofit organizations and government agencies are doing to advance sustainability; and experience sustainable products that are currently available. The competition will culminate in an awards ceremony to recognize those projects selected to receive the EPA's P3 Award, which potentially features a $75,000 grant. The Green Building Initiative, American Institute of Chemical Engineers, and the International Center for Appropriate and Sustainable Technology will announce separate awards at that time. Additionally, Duke University, in partnership with industry, will announce a new sustainability initiative at the Expo. Go to www.epa.gov/P3 to learn more about the event and competition.
