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.

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 http://www.itrcweb.ora Or http://clu-in.ora/live .

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 information and to register,

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://ciu-in.ora/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 http://www.itrcweb.ora or http://ciu-in.ora/studio .

ITRC Enhanced Attenuation of Chlorinated Organics: A Site Management Tool -
November5, 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

Principles for Greener Cleanups and Superfund Green Remediation Strategy. The

U.S. EPA has developed Principles for Greener Cleanups with the goal of reducing the
demands placed on the environment during cleanup of contaminated land, while
continuing to protect human health and the environment. Among other things, the
Principles call for EPA's cleanup programs to utilize greener approaches during any
phase of site work, and establish the goal of evaluating cleanup actions more
holistically to ensure protection of human health and the environment while reducing
the environmental footprint of cleanup activities, when feasible. Cleanups that do not
satisfy threshold requirements for protectiveness, or do not meet site specific cleanup
objectives, do not qualify as a greener cleanup. The U.S. EPA Superfund Program is
seeking public comment on an initial draft Superfund Green Remediation Strategy,
which sets out its current plans to reduce energy use and enhance the environmental
performance of remedial and non-time critical removal actions undertaken to address
hazardous waste sites. In consideration of the Principles for Greener Cleanups, the
Superfund Green Remediation Strategy is an initial effort to outline key actions and
related activities that can be undertaken to promote green remediation. These action
items fall into three major categories: policy and guidance development, resource
development and program implementation, and program evaluation. The strategy also
contains several recommendations including a call for EPA to implement a series of
near-term program initiatives and to establish a baseline of Superfund energy usage.
The public comment period is open through November 10, 2009. View the principles

and Strategy and provide comments at http://www.epa.aov/oswer/greencleanups .

Updated Emerging Contaminants Fact Sheets. The U.S. EPA Federal Facilities
Restoration and Reuse Office (FFRRO) has developed fact sheets that address
emerging contaminants of particular concern to the federal facility community. While
these contaminants present a number of issues to the government, the private sector,
and other organizations, these fact sheets are designed to provide basic information
targeted to federal facility Remedial Project Managers and other federal facility site
managers or field personnel. These fact sheets include current information on physical
and chemical properties; environmental and health impacts; existing regulatory
standards and cleanup levels; detection and treatment methods; and additional sources
