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
at http://www.itrcweb.org/Documents/RPO-2.p ... .
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 ... .
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
http://www.itrcweb.org/Documents/RPO-4 ... .
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
