Upcoming Live Internet Seminars  
  
ITRC Use of Risk Assessment in Management of Contaminated Sites  
- October 6, 2009, 2:00PM-4:15PM EDT (18:00-20:15 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

Green Remediation: Applying Strategies in the Field - October 8,  
November 12, and December 15. In June 2009, EPA held its annual  
National Association of Remedial Project Managers meeting in  
Atlanta, GA, and for the second 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. Since last year,  
experience has increased and policies are more developed, and  
this is a chance to share that with an online audience. EPA's  
Technical Support Project, led by the Engineering Forum, has  
taken this full-day session and will hold one session per month  
for 3 months starting in October. Each session will last no  
longer than 2 hours. For more information and to register, see

ITRC Performance-based Environmental Management - October 15,  
2009, 11:00AM-1:15PM EDT (15:00-17:15 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 many  
federal and private sites throughout the country, but also  
because PBEM provides an opportunity to enhance all site  
remediation. For more information and to register, see

ITRC LNAPL Training Parts 1 and 2 - October 20 and 22, 2009.  
Light non-aqueous phase liquids (LNAPLs) are organic liquids  
such as gasoline, diesel, and other petroleum hydrocarbon  
products that are immiscible with water and less dense than  
water. LNAPLs are important because they are present in the  
subsurface at thousands of remediation sites across the country,  
and are frequently the focus of assessment and remediation  
efforts. Part 1 of this training course explains how LNAPLs  
behave in the subsurface and examines what controls their  
behavior. Part 1 also explains what LNAPL data can tell you  
about the LNAPL and site conditions. Relevant and practical  
examples are used to illustrate key concepts. Part 2 addresses  
LNAPL characterization and site conceptual model development as  
well as LNAPL recovery evaluation and remedial considerations.  
Specifically, Part 2 discusses key LNAPL and site data, when and  
why those data may be important, and how to get those data. Part  
2 also discusses how to evaluate LNAPL recoverability. For more

Superfund Redevelopment Initiative (SRI) 10th Anniversary:  
Celebrating Success - October 22, 2009, 2:00PM-4:00PM EDT  
(18:00-20:00 GMT). EPA's Superfund Redevelopment Initiative  
(SRI) celebrates its 10-year Anniversary in 2009! To mark this  
event, EPA is hosting a diverse series of seminars featuring  
Superfund site reuse success stories. This and successive  
webinars will present reuse case studies on multi-use, renewable  
energy, ecological reuse, and commercial reuse. For more  
information and to register, see http://clu-in.org/sri .  
  
ITRC Quality Consideration for Munitions Response - November 3,  
2009, 2:00PM-4:15PM EST (19:00-21:15 GMT). This training  
introduces state regulators, environmental consultants, site  
owners, and community stakeholders to Quality Considerations for  
Munitions Response Projects (UXO-5, 2008), created by the ITRC's  
Unexploded Ordnance (UXO) Team. In this document, quality is  
defined as 'conformance to requirements.' To manage quality, the  
quality requirements of the project must first be understood.  
Requirements must be precisely stated and clearly understood by  
everyone involved. A plan is then put in place to meet those  
requirements. The UXO Team emphasizes taking a whole-system  
approach to designing, planning and managing a munitions  
response (MR) project to optimize quality. This training course  
is intended for an intermediate audience and assumes a basic  
understanding of specialized processes associated with MR  
projects. For more information and to register, see

ITRC Enhanced Attenuation of Chlorinated Organics: A Site  
Management Tool - November 5, 2009, 11:00AM-1:15PM EST  
(16:00-18:15 GMT). 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. For more information and to register, see
