2:00PM-3:15PM EDT (18:00-19:15 GMT). The EPA Office of Superfund Remediation
and Technology Innovation conducted a study in 2010 to explore options for
productively utilizing methane emissions from landfills that are placed on the Superfund
National Priorities List. The study included the development of the Landfill Gas Energy
Project Assessment Tool, which can be used to aid managers in conducting their own
assessment of the feasibility of installing landfill gas energy projects at landfills. The
scope of the Tool will be presented, together with a discussion of the Fresno Sanitary
Landfill in California as a comparison case study by applying the EPA LandGEM and
LFGCost models. Both LandGEM and LFGCost are routinely used by the EPA Landfill
Methane Outreach Program. Total landfill gas and methane generation for the Fresno
Sanitary Landfill were estimated using LandGEM version 3.02, released May 12, 2005,
which is an automated tool for estimating emission rates from municipal solid waste
(MSW) landfills. The model was developed by the EPA Office of Research and
Development-National Risk Management Research Laboratory, and the Clean Air
Technology Center. The model results can be used to estimate the recoverable
methane available for a potential LFG energy project. LandGEM can also be used by
landfill owners and operators to determine if a landfill is subject to the control
requirements of the federal New Source Performance Standard (NSPS) for new MSW
landfills, the emission guidelines for existing MSW landfills, or the National Emission
Standards for Hazardous Air Pollutants (NESHAP) for MSW landfills. In evaluating the
economic feasibility of an LFG energy project at the Fresno Sanitary Landfill, EPA's
LFGcost Tool was utilized. This webinar will review the assumptions made in the Tool
and the resulting economic outlook for a potential project at this site. For more

services, what to plan for in terms of costs and schedule, or how to confirm and quality
check results. This two-hour seminar will: (1) describe the setup and use of 3-D data
visualization systems; (2) show how visualization and analysis can help resolve a
number of common, but critical, issues at environmental cleanup sites; (3) identify best
management practices developed from a broad range of Superfund site 3-D
visualization applications; (4) describe quality control procedures when using 3-D
visualization for analyzing existing data in EPA investigations; (5) and present
guidelines for contracting 3-D visualization and analysis services. The seminar will also
demonstrate how 3-D visualization and analysis was used to maximize the value of
existing site data at the Time Oil/Well 12A Superfund Site in Tacoma, Washington.
Under active remediation since 1988, the site has not reached the goals identified in
the Record of Decision (ROD). At this site, 3-D data visualization/analysis was utilized
extensively for defining present site conditions and providing a comprehensive
conceptual site model (CSM) for evaluation and selection of remedial actions designed
to reach a workable exit strategy. An open forum will be held after the presentations,
during which participants will be able to submit questions and feedback to the
speakers. For more information and to register, see http://ciu-in.ora/iive .

ITRC Project Risk Management for Site Remediation - September 27, 2011,
2:00PM-4:15PM EDT (18:00-20:15 GMT). Remediation Risk Management (RRM) is a
course of action through which all risks related to the remediation processes (site
investigations, remedy selection, execution, and completion) are holistically addressed
in order to maximize the certainty in the cleanup process to protect human health and
the environment. Remediation decisions to achieve such a goal should be made based
on threshold criteria on human health and ecological risks, while considering all the
other potential project risks. Through this training course and associated ITRC
Technical and Regulatory Guidance Document: Project Risk Management for Site
Remediation (RRM-1, 2011), the ITRC RRM team presents tools and processes that
can help the site remediation practitioner anticipate, plan for, and mitigate many of the
most common obstacles to a successful site remediation project. Examples of project
risks include remediation technology feasibility risks; remedy selection risks; remedy
construction, operation and monitoring risks; remedy performance and operations risks;
environmental impacts of systems during their operation; worker safety risk, human
health and ecological impacts due to remedy operation; as well as costs and schedules
risks including funding and contracting issues. For more information and to register,

ITRC Mine Waste Treatment Technology Selection - September 29, 2011,
11:00AM-1:15PM EDT (15:00-17:15 GMT). ITRC's Mining Waste Team developed the
ITRC Web-based Mine Waste Technology Selection site

(http://www.itrcweb.ora/mininawaste-auidance/^ to assist project managers in selecting an applicable
technology, or suite of technologies, which can be used to remediate mine waste
contaminated sites. Decision trees, through a series of questions, guide users to a set
of treatment technologies that may be applicable to that particular site situation. Each
technology is described, along with a summary of the applicability, advantages,
limitations, performance, stakeholder and regulatory considerations, and lessons
learned. Each technology overview links to case studies where the technology has
been implemented. In this associated Internet-based training, instructors provide
background information then take participants through the decision tree using example
sites. Project managers, regulators, site owners, and community stakeholders should
attend this training class to learn how to use the ITRC Web-based Mine Waste
Technology Selection site to identify appropriate technologies, address all impacted
media, access case studies, and understand potential regulatory constraints. For more

range of materials with a variety of applications, including those relevant to Superfund
sites. As with any new technology, concerns have been raised about the potential for
human toxicity and environmental impact of nanoparticles. In this two-part seminar,
investigators from the National Institute of Environmental Health Sciences Superfund
Research program (SRP) will explore the implications of nanoparticles on human
health, as well as applications of nanotechnology-based environmental sensing.
Remediation of Superfund sites can release nanoscale particles into the environment,
which can pose exposure risks. The health effects of these complex mixtures and
materials, especially emerging materials produced by the nanotechnology industry, are
not sufficiently well understood. Dr. Ian Kennedy, of the University of California-Davis
SRP, will discuss the potential for adverse environmental effects and human health
effects that can arise from exposure to both intentionally manufactured and
unintentionally produced nanomaterials. The primary focus will be on metals and metal
oxide nanomaterials. There remains a compelling need for improved ways to detect and
quantify toxic and/or hazardous chemical species found at existing or potential
Superfund sites. Better analytical techniques could reduce the cost of monitoring, help
improve remediation methods, and more accurately assess the health risks associated
with hazardous and toxic species. Nanoscale materials provide an opportunity to
develop new methods that could be faster, easier, smaller, and/or less expensive. Dr.
Donald Lucas, of the Lawrence Berkeley National Laboratory, and a member of the
University of California-Berkeley SRP, will discuss how changing the size of materials
to the nanoscale changes their properties. These changes can be exploited to produce
sensors and detectors that the potential to reduce the cost and improve detection limits.
Examples include the use of controlled shape silver and gold nanoparticles to detect
arsenic and mercury in air and water. For more information and to register, see
