Superfund Landfill Methane Potential Assessment - September 14, 2011, 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 information and to register, see .

Use of Geostatistical 3-D Data Visualization/Analysis in Superfund Remedial Action Investigations - September 23, 2011, 1:00PM-3:00PM EDT (17:00-19:00 GMT). Three-dimensional (3-D) visualization and analysis is being used with increasing frequency to improve the effectiveness environmental investigation and cleanup efforts. Many potential users, however, are not readily aware of how visualization and analysis methods can be used to support their projects at various stages in a project lifecycle, how the software programs really work, what to consider when scoping and procuring 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 .

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.

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 ( 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.

Nanotechnology: Implications and Applications - October 3, 2011, 1:00PM-3:00PM EDT (17:00-19:00 GMT). Nanotechnology encompasses a diverse 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 .
