Webcast Seminars  
  
Real Estate Finance Basics - May 9. This seminar is a  
concentrated introduction to the core concepts of real estate finance  
and development. Topics include market analysis and feasibility,  
the financing of environmentally challenged properties, the impact  
of leverage, and property valuation techniques. For more  
information and to register, see http://clu-in.org/studio .  
  
ITRC What's New with In Situ Chemical Oxidation? - May 11.  
This seminar presents updated guidance and technology  
advancement information for In Situ Chemical Oxidation. Topics  
include a regulatory discussion related to ISCO implementation;  
details on the chemistry behind ISCO technology; considerations  
for system design and application, including health and safety; and  
performance evaluation information. The course is based on the  
ITRC's In Situ Chemical Oxidation of Contaminated Soil and  
Groundwater, Second Edition (ISCO-2, 2005), with sections on  
technology overview and applicability, remedial investigations,  
safety concerns, regulatory concerns, injection design, monitoring,  
stakeholder concerns, and case studies. For more information and  
to register, see http://www.itrcweb.org or http://clu-in.org/studio .  
  
ITRC Site Investigation and Remediation for Munitions  
Response Projects - May 18. This training provides an  
introduction and overview of the processes, tools, and techniques  
used in investigation and remediation. These concepts are  
illustrated using an example munitions response site. Major steps  
in each process are identified and key regulatory considerations  
discussed. This training also identifies additional sources for more  
detailed information on key aspects of investigation and  
remediation. State regulators and others who need to understand  
the general processes involved in these critical aspects of the  
munitions response process will benefit from this training. For  
more information and to register, see http://www.itrcweb.org or

New Documents and Web Resources  
  
Off-Gas Treatment Technologies for Soil Vapor Extraction  
Systems: State of the Practice (EPA 542-R-05-028).  This  
document, produced by the EPA Office of Superfund Remediation  
and Technology Innovation, provides state-of-the-practice  
information on off-gas treatment technologies for soil vapor  
extraction systems currently being used to clean up hazardous  
waste sites. It provides information on common practices such as  
carbon adsorption and thermal oxidation, less frequently used  
technologies such as biofiltration, and emerging alternatives  
including photocatalytic and non-thermal plasma treatment. The  
report presents the state of the practice for these technologies based  
on applicability, limitations, performance, engineering  
considerations, residuals management, cost and economics, and  
developmental status (March 2006, 129 pages).  View or download

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

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

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).  View or download at

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).

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).  View or

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
