Slides for "Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites," Jan 26, 2012

Interstate Technology and Regulatory Council — Thu, 26 Jan 2012 23:00:00 GMT

The U.S. Environmental Protection Agency estimates that approximately 10 percent (over a billion cubic yards) of the sediment underlying our nation's surface water is sufficiently contaminated with pollutants to pose potential risks to fish and to humans and wildlife that eat fish. Based on current average costs for managing contaminated sediments, this volume of material could cost several trillion dollars to dredge. Methods to assess the potential effect of sediment contamination on human or ecological health are historically based on total contaminant concentrations in the bulk sediment. However, research conducted over the past fifteen years has shown that the bioavailability of many of these contaminants to receptors is much less than the total amount of contaminant in the sediment. "Bioavailability processes," as defined by the National Research Council, are the "individual physical, chemical, and biological interactions that determine the exposure of plants and animals to chemicals associated with soils and sediments." Only the bioavailable fraction of an environmental contaminant may be taken up and subsequently result in an effect on an organism. Incorporating bioavailability considerations in the calculation of risk can optimize the extent of cleanup required to be protective, improve site decision-making, and can be an important factor in balancing the risks caused by remedial action with the risks addressed by remedial action. ITRC's web-based Technical and Regulatory Guidance, Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites (CS-1, 2011) and associated Internet-based training are intended to assist state regulators and practitioners with understanding and incorporating fundamental concepts of bioavailability in contaminated sediment management practices. This guidance and training describe how bioavailability considerations can be used to evaluate exposure at contaminated sediment sites, the mechanisms affecting contaminant bioavailability, available tools used to assess bioavailability, the proper application of those tools, and how bioavailability information can be incorporated into risk-management decisions. This guidance and training also contain summaries of case studies where bioavailability has been assessed and considered in the contaminated sediment remedial decision making process. This guidance and training provide insight on how bioavailability assessments can be used to understand, mitigate, and manage risk at a contaminated sediment site, often at a reduced overall project cost. The intended users of this guidance and training participants are individuals who have a working knowledge of contaminated sediment management but seek additional information about bioavailability. Prior to the training class, participants are encouraged to review the following documents: ITRC's web-based Technical and Regulatory Guidance, Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites (CS-1, 2011) http://www.itrcweb.org/contseds-bioavailability U.S. Environmental Protection Agency, "Ecological Risk Assessment Guidance for Superfund: Process for Designing and Conducting Ecological Risk Assessment"- Interim Final, June 1997 http://www.epa.gov/oswer/riskassessment/ecorisk/ecorisk.htm U.S. Environmental Protection Agency, "Risk Assessment Guidance for Superfund (RAGS)" Volume 1 -- Human Health Evaluation Manual, Supplement to Part A: Community Involvement in Superfund Risk Assessments, 1989 http://www.epa.gov/oswer/riskassessment/ragsa/ci-ra.htm

Slides for "Development of Performance Specifications for Solidification/Stabilization," Jan 12, 2012

Interstate Technology and Regulatory Council — Thu, 12 Jan 2012 23:00:00 GMT

Solidification/Stabilization (S/S) is a remedial technology option which blends treatment reagents into contaminated material to impart physical and/or chemical changes to reduce the flux of contamination that leaches from a contaminant source to within acceptable parameters set forth in a site-specific remediation goal. S/S can be effective for metals, asbestos, radioactive materials, oxidizers, PAHs, PCBs, and pesticides and is potentially effective for dioxins/furans, some VOCs and other organics. Although there is abundant literature describing the S/S process and test methods for design and implementation, there was a lack of guidance for assessing performance. The ITRC technical and regulatory guidance document Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) and associated Internet-based training provide an approach to assist practitioners and regulators with measuring and determining acceptable S/S performance. This approach developed by the ITRC Solidification/Stabilization Team provides information for developing, testing, and evaluating appropriate site-specific performance specifications and the considerations for designing appropriate long-term stewardship programs. In addition, the approach provides useful tools for establishing an appropriate degree of treatment and regulatory confidence in the performance data to support decision-making. This training and guidance is intended to be beneficial to anyone involved with CERCLA, RCRA, brownfields, UST or any other regulatory program where S/S has been selected or implemented as a remedial technology. For reference during the training class, participants should have available a copy of the process diagram, Figure 4-1 on page 29 of the ITRC Technology and Regulatory Guidance Document Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/ss/ITRC-SS-Process.pdf.

Slides for "Mine Tailings: Enumeration and Remediation," Jan 11, 2012

Wed, 11 Jan 2012 23:00:00 GMT

This seminar will feature Dr. Eric Betterton and Dr. Raina Maier from the University of Arizona Superfund Research Program and will focus on field trials being performed at mining sites in Arizona. Mine tailings are large piles of crushed rock leftover after the minerals of interest have been processed. They often do not support establishment of a plant cover, are prone to wind and water erosion, and may contribute to the dispersion of associated metal toxicants. Dr. Eric Betterton will discuss size-selective characterization of aerosols collected with samplers called "Multiple Orifice Uniform Deposit Impactors" at two Arizona mining sites, the Asarco plant in Hayden, AZ, and the Iron King Mine and Humboldt Smelter Superfund site in Dewey-Humboldt, AZ. Chemical speciation shows that arsenic and lead occur preferentially in the submicron fraction at both sites; lead isotope analysis shows great promise for source apportionment at both sites; and scanning electron microcopy shows evidence for spherical particle formation by high-temperature processing at Hayden. Data from dust flux towers installed at Iron King, and dust modeling studies will be described. Dr. Raina Maier will discuss phytostabilization, a technology being investigated for remediation of mine tailings sites in arid and semi-arid environments. The goal is to create a vegetative cap using native plants that will 1) prevent wind and water erosion of the tailings, 2) stabilize metal contaminants in the rooting zone, and 3) avoid shoot uptake of metal contaminants. The Iron King Mine and Humboldt Smelter Superfund Site is adjacent to the town of Dewey-Humboldt, Arizona. Soil in residential yards contains elevated levels of arsenic, lead, and zinc associated with tailings particles that have been dispersed as dust, primarily by wind. Working together with the site owner and Region 9 EPA, a phytostabilization trial was initiated on site in May 2010, which was further expanded in 2011, using native plants that were shown to meet successful phytostabilization criteria in preliminary greenhouse trials. The site is being monitored to determine whether greenhouse results can be successfully translated to the field and to examine changes in chemical, physical, and biological properties of the tailings as phytostabilization occurs.

Slides for "Integrated DNAPL Site Strategy," Jan 10, 2012

Interstate Technology and Regulatory Council — Tue, 10 Jan 2012 23:00:00 GMT

Sites contaminated by chlorinated solvents present a daunting environmental challenge, especially at sites with dense nonaqueous phase liquid (DNAPL) still present. Restoring sites contaminated by chlorinated solvents to typical regulatory criteria (low parts-per-billion concentrations) within a generation (~20 years) has proven exceptionally difficult, although there have been successes. Site managers must recognize that complete restoration of many of these sites will require prolonged treatment and involve several remediation technologies. To make as much progress as possible requires a thorough understanding of the site, clear descriptions of achievable objectives, and use of more than one remedial technology. Making efficient progress will require an adaptive management approach, and may also require transitioning from one remedy to another as the optimum range of a technique is surpassed. Targeted monitoring should be used and re-evaluation should be done periodically. This ITRC Integrated Dense Nonaqueous Phase Liquid Site Strategy (IDSS-1, 2011) technical and regulatory guidance document will assist site managers in development of an integrated site remedial strategy. This course highlights five important features of an IDSS including: A conceptual site model (CSM) that is based on reliable characterization and an understanding of the subsurface conditions that control contaminant transport, reactivity, and distribution Remedial objectives and performance metrics that are clear, concise, and measureable Treatment technologies applied to optimize performance and take advantage of potential synergistic effects Monitoring based on interim and final cleanup objectives, the selected treatment technology and approach, and remedial performance goals Reevaluating the strategy repeatedly and even modifying the approach when objectives are not being met or when alternative methods offer similar or better outcomes at lower cost This IDSS guidance and training is intended for regulators, remedial project managers, and remediation engineers responsible for sites contaminated by chlorinated solvents. Because the subject matter is complex, this guidance assumes a functional understanding of the field and is targeted towards experienced users; however, novices will benefit through descriptions and references of the latest evolution of site characterization challenges; realistic planning of site restoration; evolving treatment techniques; and evaluating, monitoring and interpreting mass transport in the subsurface aqueous and vapor phases. While the primary focus of the document is on DNAPL sites, other types of contaminated sites (e.g. petroleum, mixed contaminants, etc.) can use the same fundamental process described in this guidance. For reference during the training class, participants should have a copy of the flow diagram, Figure 1-2 on page 6 of the ITRC Technical and Regulatory Guidance document, ITRC Integrated Dense Nonaqueous Phase Liquid Site Strategy (IDSS-1, 2011) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/IDSS/ITRC-IDSS-1-Figure1-2.pdf.

Slides for "LNAPL Characterization and Recoverability - Improved Analysis - Part 2," Dec 13, 2011

Interstate Technology and Regulatory Council — Tue, 13 Dec 2011 23:00:00 GMT

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. Understanding LNAPLs is important because they are present in the subsurface at thousands of remediation sites across the country, and are often the sole reason why a site remains "open." The spectrum of sites where LNAPL assessment and remediation efforts may take place include petroleum manufacturing and handling facilities such as refineries, bulk product terminals, gas stations, airports and military bases. LNAPLs in the subsurface can be a complex problem to address, and frequently prevent or delay regulatory closure (no further action) of remediation projects. This training course is relevant for all levels of state and federal regulators, environmental consultants, and technically-inclined site owners and public stakeholders. The training course is divided into three parts: An Improved Understanding of LNAPL Behavior in the Subsurface - State of Science vs. State of Practice LNAPL Characterization and Recoverability-- Improved Analysis Evaluating LNAPL Remedial Technologies for Achieving Project GoalsPart 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. A sound LNAPL understanding is necessary to effectively characterize and assess LNAPL conditions and potential risks, as well as to evaluate potential remedial technologies or alternatives. Unfortunately, many environmental professionals have a faulty understanding of LNAPL conditions based on outdated paradigms. The ITRC LNAPLs Team is providing Internet-based training to improve the general understanding of LNAPLs. Better understanding leads to better decision making. Additionally, this training provides a necessary technical foundation to foster effective use of the ITRC LNAPLs Team Technical and Regulatory Guidance document, Evaluating LNAPL Remedial Technologies for Achieving Project Goals (LNAPL-2, 2009).

Slides for "Biofuels: Release Prevention, Environmental Behavior, and Remediation," Dec 6, 2011

Interstate Technology and Regulatory Council — Tue, 6 Dec 2011 23:00:00 GMT

Biofuels and biofuel blends are a new category of transportation fuels and are defined as liquid fuels and blending components produced from renewable biomass feedstocks used as alternative or supplemental fuels for internal combustion engines. Their manufacture and consumption are increasing, in part, due to usage mandates and incentives both in the United States and abroad. This expanded use of biofuel and biofuel blends increases the potential frequency of releases due to increased manufacture, transportation, storage, and distribution. Because biofuels differ from conventional fuels with respect to their physical, chemical, and biological properties, their introduction poses challenges with respect to understanding the potential impacts of releases to the environment. Specifically, once released into the environment, these fuels will exhibit different environmental behaviors as compared to conventional fuels. This training, which is based on the ITRC's Biofuels: Release Prevention, Environmental Behavior, and Remediation (Biofuels-1, 2011), focuses on the differences between biofuels and conventional fuels specific to release scenarios, environmental impacts, characterization, and remediation. The trainers will define the scope of the potential environmental challenges by introducing biofuel fundamentals, regulatory status, and future usage projections. Participants will learn how and when to use the ITRC biofuels guidance document for their projects. They will understand the differences in biofuel and petroleum behavior; become familiar with the biofuel supply chain, potential release scenarios and release prevention; be able to develop an appropriate conceptual model for the investigation and remediation of biofuels; and select appropriate investigation and remediation strategies.

Dr. Burken will present his work using traditionally high pressure waterjet in a new and innovative manner to inject remediation amendments such as powdered activated carbon at varying depths in contaminated sediments. This method also decreases contaminant bioavailability and minimizes resuspension and the impact on benthic communities. Waterjet placement can be applied for a suite of amendments targeting nearly all common sediment contaminants, specifically polychlorinated biphenyls (PCB), polycyclic aromatic hydrocarbons (PAH), and redox sensitive metals. In addition, the waterjet can be used for sediments with overlaying caps.

Slides for "Use and Measurement of Mass Flux and Mass Discharge," Nov 3, 2011

Interstate Technology and Regulatory Council — Thu, 3 Nov 2011 23:00:00 GMT

Most decisions at groundwater contamination sites are driven by measurements of contaminant concentration -- snapshots of contaminant concentrations that may appear to be relatively stable or show notable changes over time. Decisions can be improved by considering mass flux and mass discharge. Mass flux and mass discharge quantify the source or plume strength at a given time and location resulting in better-informed management decisions regarding site prioritization or remedial design as well as lead to significant improvements in remediation efficiency and faster cleanup times. The use of mass flux and mass discharge is increasing and will accelerate as field methods improve and practitioners and regulators become familiar with its application, advantages, and limitations. The decision to collect and evaluate mass flux data is site-specific. It should consider the reliability of other available data, the uncertainty associated with mass flux measurements, the specific applications of the mass flux data, and the cost-benefit of collecting mass measurements. The ITRC technology overview, Use and Measurement of Mass Flux and Mass Discharge (MASSFLUX-1, 2010), and associated Internet-based training provide a description of the underlying concepts, potential applications, description of methods for measuring and calculating, and case studies of the uses of mass flux and mass discharge. This Technology Overview, and associated internet based training are intended to foster the appropriate understanding and application of mass flux and mass discharge estimates, and provide examples of use and analysis. The document and training assumes the participant has a general understanding of hydrogeology, the movement of chemicals in porous media, remediation technologies, and the overall remedial process. Practitioners, regulators, and others working on groundwater sites should attend this training course to learn more about various methods and potential use of mass flux and mass discharge information.

Slides for "Terrestrial Carbon Sequestration: An Ecosystem Service Provided by Using Soil Amendments for Site Remediation and Reuse," Oct 27, 2011

U.S. EPA Office of Superfund Remediation and Technology Innovation — Thu, 27 Oct 2011 23:00:00 GMT

Contaminated land remediation and reuse can provide ecosystem services, the life-sustaining benefits that people receive from nature such as clean air and water, flood control, climate regulation, recreational opportunities, etc. Soil amendments such as municipal biosolids, animal manures and litters, sugar beet lime, wood ash, among others, are being increasingly used in soil remediation, revegetation, reuse, and ecological revitalization of contaminated properties. In addition to reducing exposure to contaminants at these sites, soil amendments also provide important ecosystem services by restoring soil quality though balancing pH, adding organic matter, increasing water holding capacity, re-establishing microbial communities, and reducing soil compaction. Another important ecosystem service or co-benefit of using soil amendments for remediation is terrestrial carbon sequestration, the process through which carbon dioxide from the atmosphere is absorbed by trees and plants through photosynthesis and stored as carbon in soils and biomass. To date, little research has been published evaluating and quantifying terrestrial carbon sequestration benefits associated with contaminated lands remediated with soil amendments (i.e., Superfund sites, Brownfield sites, etc.). The U.S. Environmental Protection Agency (EPA) conducted a field study and modeling exercise on contaminated land. For the field study, EPA collected and analyzed samples at three field sites to quantify soil carbon sequestration rates after treatment with soil amendments. As part of this study, EPA developed a methodology for field sampling and analysis of carbon in soils at amended sites. EPA's modeling project involved predicting changes in four ecosystem services as a function of remedy implementation activities. This seminar will discuss the importance of the use of soil amendments in the context of soil health and ecosystem services and provide details about the EPA field study and modeling exercise.

Slides for "Permeable Reactive Barrier: Technology Update," Oct 18, 2011

Interstate Technology and Regulatory Council — Tue, 18 Oct 2011 23:00:00 GMT

A Permeable Reactive Barrier (PRB) is an in situ permeable treatment zone designed to intercept and remediate a contaminant plume to remediate groundwater. The treatment zone may be created directly using reactive materials such as iron, or indirectly using materials designed to stimulate secondary processes (e.g., adding carbon substrate and nutrients to enhance microbial activity). Since its first implementation in the early 1990s, over 200 PRB systems have been installed to treat groundwater contaminants and PRBs have become an important component among the various technologies available to remediate groundwater contamination. The ITRC Technical/Regulatory Guidance Permeable Reactive Barrier: Technology Update (PRB-5, 2011) and associated Internet-based training is intended to help guide state and federal regulators, consultants, project managers, and other stakeholders and technology implementers through the decision process when a PRB is being considered as a remedy, or part of a remedy, to address contaminated groundwater; and to provide updated information regarding several technical aspects of the PRB using information attained from the more than 15 years that the PRB has been a viable and accepted in situ remediation technology for contaminated groundwater. The guidance and training provides an update on PRBs to include discussions of additional types of reactive media and contaminants that can be treated, design considerations, construction/installation approaches and technologies, performance assessment, and longevity. If you are unfamiliar with PRBs, we ask that you review background information on PRBs prior to attending the training class. Documents produced by the ITRC PRB team are available for review on the ITRC Permeable Reactive Barriers Guidance Documents page. You can access archives of previous ITRC trainings at http://www.clu-in.org/conf/itrc/advprb_032102/, http://www.clu-in.org/conf/itrc/prb_031902/, and http://www.clu-in.org/conf/itrc/prbll_061506/.

Slides for "A Decision Framework for Applying Attenuation Processes to Metals and Radionuclides," Oct 13, 2011

Interstate Technology and Regulatory Council — Thu, 13 Oct 2011 23:00:00 GMT

Sites contaminated with metals and radionuclides present unique challenges to the development of effective remedial alternatives that also provide long-term protection to human health and the environment. The high costs of ongoing conventional treatment, total removal, and/or management combined with the scale of potential health and environmental risks make it important to evaluate attenuation-based remedial alternatives. Sites that have been identified as having metal and/or radionuclide contamination include federal facilities, industrial (e.g., mines) sites, disposal sites, and transportation corridors. Common metals include arsenic, cadmium, chromium, lead, nickel, copper, and selenium. For radioactive hazardous substances, uranium, radium, strontium, technetium, tritium, and thorium are the most common contaminants of concern. The attenuation processes affect most metals and radionuclides by changing their valence state, which in turn affects their solubility and therefore mobility. When properly employed, Monitored Natural Attenuation (MNA) is an effective knowledge-based remedy where a thorough engineering analysis informs the understanding, monitoring, predicting, and documenting of natural processes. In order to properly employ this remedy, there needs to be a strong scientific basis supported by appropriate research and site-specific monitoring implemented in accordance with quality systems. This training and the associated ITRC Technical and Regulatory Guidance document, A Decision Framework for Applying Monitored Natural Attenuation Processes to Metals and Radionuclides in Groundwater (APMR-1, 2010), is intended for anyone involved with evaluating, investigating, remediating or managing a site that involves metal and radionuclide contaminants in groundwater. This training and document provides: Introduction to key attenuation processes for metals and radionuclides Information on incorporating MNA into remedial alternatives for metals/rads Overview of the decision framework on MNA for metals and radionuclides in groundwater within the larger evaluation framework of a contaminated siteFor reference during the training class, participants should have a copy of the decision framework, Figure 3-1 on page 48 of the ITRC Technical and Regulatory Guidance document, A Decision Framework for Applying Monitored Natural Attenuation Processes to Metals and Radionuclides in Groundwater (APMR-1, 2010) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/apmr/ITRC-APMR-DecisionFramework.pdf.

Slides for "Nanotechnology: Implications and Applications," Oct 3, 2011

Mon, 3 Oct 2011 23:00:00 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 have 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.

Slides for "Use of Geostatistical 3-D Data Visualization/Analysis in Superfund Remedial Action Investigations," Sep 23, 2011

U.S. EPA, Technology Innovation and Field Services Division — Fri, 23 Sep 2011 23:00:00 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.

Slides for "Superfund Landfill Methane Potential Assessment," Sep 14, 2011

U.S. EPA, Office of Superfund Remediation and Technology Innovation — Wed, 14 Sep 2011 23:00:00 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.

Slides for "Use of Risk Assessment in Management of Contaminated Sites," Aug 30, 2011

Interstate Technology and Regulatory Council — Tue, 30 Aug 2011 23:00:00 GMT

The ITRC Risk Assessment Resources team developed a document titled Use of Risk Assessment in Management of Contaminated Sites (RISK-2, 2008). This Internet-based training is taken from the RISK-2 document and highlights variation of risk-based site management and how to improve the use of risk assessment for making better risk management decisions. This training course looks at how various risk-based approaches and criteria are applied in various states and programs throughout the processes of screening, characterization, and management of contaminated sites. The document and training course are intended for risk assessors and project managers involved with the characterization, remediation, and/or re-use of sites. Together they 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. This training course explains: Variation in risk assessment parameters/approaches in various states and their influence on risk management Insights into the use of risk assessment in risk management process through use of specific case study examples An improved process of using risk assessment in risk management This course builds on the Risk Team's previous work identifying variation in the development of risk-based numerical criteria, specifically soil screening levels. A prerequisite to this training course is the Risk Team's previous Internet-based training (archive is available from http://cluin.org/live/archive.cfm?sort=title#itrc) based on ITRC's Risk Assessment and Risk Management: Determination of Risk-Based Values (RISK-1, 2005). The Electronic Risk Resource Sheet published by the ITRC Risk Team is recommended as an excellent resource for supplemental materials related to risk assessment and risk management.

The process of cleaning up a hazardous waste site uses energy, water, and other natural or materials resources and consequently creates an environmental footprint of its own. The US EPA is developing a methodology for evaluating the environmental footprint in order to reduce the footprint and improve the outcome of cleanup under any regulatory program. EPA will host an interactive Internet seminar to provide information about the environmental footprint assessment methodology and to obtain feedback from the environmental remediation community. This two-hour seminar will: (1) discuss the metrics for environmental footprint assessment and the methodology for estimating or quantifying the footprint; and (2) provide an interactive case study to allow participants to get a feel for the process of calculating an environmental footprint and evaluating options to reduce it. An open forum will be held after the presentations, during which participants will be able to submit questions and feedback to the speakers.
