EPA Solicits Innovative Ideas and Technological Solutions for
Enbridge Oil Spill. EPA has developed a voluntary submittal
process to allow for faster review of the suggestions being
offered and to provide guidance regarding what information would
be most useful to the reviewing officials. The information
received through this voluntary submittal process will be
scrutinized for innovative ideas and technological solutions
that are safe for the environment and public health and can be
deployed along the Kalamazoo River to help with cleanup. The
information submitted will be forwarded to the appropriate
reviewing official who will contact submitters, if necessary.
For more information or to submit a technical solution, go to
the EPA Enbridge Oil Spill web site at

Upcoming Live Internet Seminars
ITRC LNAPL Training Parts 1, 2, and 3 - August 3, 10, and 17,
2010. 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. Part 3
uses the LNAPL conceptual site model (LCSM) approach to identify
the LNAPL concerns or risks and set proper LNAPL remedial
objectives and technology-specific remediation goals and
performance metrics. Part 3 also provides an overview of the
LNAPL remedial technology selection framework. For more

The Charrette: Redevelopment by Design - August 11, 2010,
2:00PM-3:30PM EDT (18:00-19:30 GMT). A Charrette uses pictures
and mapping tools to develop innovative, sustainable plans for
revitalization. Traditional planning and negotiation efforts can
be stymied by the complex issues and divergent perspectives,
leaving all parties frustrated. These collaborative workshops
help participants visually understand the complexities of land
re-use and revitalization. They have made a difference across
the country by moving the affected stakeholders from negative
approaches to positive plans for the future. This training will
help EPA employees explore the use of Charrettes for
collaborative redevelopment of Superfund sites. For more
information and to register, see http://clu-in.org/live .
Identifying & Evaluating Ecosystem Services at Contaminated
Sites Prior to Remediation - August 18, 2010, 3:00PM-4:30PM EDT
(19:00-20:30 GMT). Green remediation is the practice of
considering all environmental effects of remedy implementation
and incorporating options to maximize net environmental benefits
of cleanup actions at contaminated sites. One of the core
elements of green remediation is land & ecosystems, which
promotes ideas of land management and ecosystem protection.
There is a growing recognition of the significance of ecosystem
services, as well as the dramatic impacts human activities can
have on these essential services. Ecosystem services are the
benefits that human populations derive from ecosystems.
Examples include erosion control, climate regulation,
recreational opportunities and raw materials. There is a unique
opportunity to mitigate impacts on ecosystem services, which may
occur from the remediation of contaminated sites. Learn more
about ecosystem services, opportunities to mitigate impacts on
ecosystem services at a site level, and much more during this
seminar brought to you by Sarah Slack, a NNEMS fellow at the
EPA. For more information and to register, see

PAH and PCB Toxicity and Adaptation - Lessons Learned from
Chronically Exposed Wild Populations - August 19, 2010,
2:00PM-4:00PM EDT (18:00-20:00 GMT). This seminar will feature
Dr. Mark E. Hahn of Woods Hole Oceanographic Institution and Dr.
Richard T. Di Giulio, Director of Duke University's Integrated
Toxicology Program. Dr. Hahn will describe research to
understand the role of aryl hydrocarbon receptors (AHRs) and AHR
variants in the mechanism of resistance to PCBs that has evolved
in Atlantic killifish (Fundulus heteroclitus) inhabiting the New
Bedford Harbor (MA) superfund site. Other studies that address
the role of AHRs as biomarkers of susceptibility and resistance
will be discussed. Dr. Di Giulio will describe studies
addressing mechanisms underlying the marked resistance to PAH
toxicity displayed by a population of Atlantic killifish
(Fundulus heteroclitus) inhabiting a PAH contaminated estuary
adjacent to the Atlantic Woods Industries Superfund site in
Virginia. These studies subsequently motivated additional
studies that will be described that examined the unanticipated
phenomenon of synergisitc toxicity between certain PAHs. These
latter studies included both the killifish and the zebrafish as
models. For more information and to register, see

Understanding the FY11 Job Training Grant Application Guidelines
- August 30, 2010, 2:00PM-4:00PM EDT (18:00-20:00 GMT). This
seminar will provide an overview of the FY11 application
guidelines for the Environmental Workforce Development and Job
Training Grants - formerly known as the 'Brownfields Job
Training Grants,' and is specifically geared towards tribal,
tribal and minority academic institution applicants (however,
anyone is free to attend). See the second session on September 2
