Filing EPA Information in AES Targeted at Current Exporters Only

Exporters of manifested hazardous wastes, spent/used lead-acid batteries, universal wastes and cathode ray tubes for recycling should now be transitioning to an electronic border process using the Automated Export System (AES) or AESDirect. This 30-minute webinar will provide detailed filing instructions for exporters and their authorized filing agents (e.g., customs brokers) on how to file the RCRA information about their shipments in AES and AESDirect.

Requirements That Apply to Import and Export Shipments That Go to Both an Interim and Final Destination Facility

Exports and imports of hazardous wastes, including those managed as universal waste and spent lead-acid batteries, are required to follow import and export procedures under 40 CFR Part 262 Subpart H. But shipments going first to an interim facility for temporary holding or consolidation prior to being shipped to a final disposal or recycling facility have special procedures to follow. This 1-hr webinar will walk through the additional information to provide in your notices and the shipment-specific tracking procedures you must follow to comply with 40 CFR Part 262 Subpart H.

OSC Academy Presents...ESA and NHPA for OSCs and RPMs

The course provides OSCs and RPMs with an overview of the Endangered Species Act (ESA) and Section 7 requirements under EPA's Emergency Response and Removal Program, including a discussion of the responsibility to consider the effects of its actions on listed species and their habitat and the components of Section 7 consultation.

The course also provides OSCs and RPMs with an overview of the National Historic Preservation Act (NHPA) and Section 106 requirements under EPA's Emergency Response and Removal Program, including a discussion of its responsibility to consider the effects of its undertakings on historic properties and the components of Section 106 review.

The primary audience for this training is EPA OSCs and RPMs; however, it is open to other federal agencies, states, tribes and consultants who are interested in learning more about the ESA and NHPA statutes.

Superfund Redevelopment Initiative Series: Opportunities for Reuse at Capped Sites

Former landfills, abandoned dumps, and other contaminated sites throughout the United States, once thought to be of limited value, are being transformed into viable commercial and industrial developments, parks and other recreational areas, and wildlife areas. With forethought and effective planning, communities and site stakeholders can return sites to productive use without jeopardizing the effectiveness of a remedial cap. This webinar will share lessons learned from the successful reuse and assessment of capped sites.

Superfund Redevelopment Initiative Series: Highlighting Beneficial Economic Impacts at Superfund Sites

Site redevelopment can revitalize a local economy with jobs, new businesses, tax revenues and local spending. This webinar will showcase new economic case studies across the country with different types of development- large and small, commercial and public, even new transportation options to show how they can all have beneficial impacts on the surrounding community.

Military Munitions Support Services - Stakeholder Collaboration on MMRP Projects

This session will discuss challenges and successes of interagency collaborative efforts on munitions response projects.

Military Munitions Support Services - Making Decisions

This session will discuss critical elements and concepts of the decision making process.

Military Munitions Support Services - MMRP Explosive Safety

This session will discuss updated safety developments when dealing with scrappers, underwater issues and the 3 R's.

Overview, Lessons Learned and Best Practices Derived from Independent Optimization Reviews of Superfund Mining Sites

This webinar presents an overview of the EPA Office of Superfund Remediation and Technology Innovation (OSRTI) "Mine Site Optimization Initiative," and summarizes the lessons learned identified and best practices derived from independent optimization reviews performed on over 30 Superfund mine sites and mining district sites nationwide. The initiative is being performed under the EPA's National Strategy to Expand Superfund Optimization Practices from Site Assessment to Site Completion, which expanded and formalized optimization practices as an operating business model for the Superfund remedial program. The webinar will present case studies of mine site reviews performed, a summary of specific lessons learned identified for site characterization, and an update on the development of best practices resources to support consistent and safe approaches to characterization of mine sites with the potential for sudden, uncontrolled release of mining-influenced waters.

Analytical Tools and Methods: Session III - Fate and Transport of Contaminants

This webinar series highlights innovative analytical tools and methods developed and used by Superfund Research Program (SRP) grantees. During the third session of the series, speakers will highlight tools and methods to detect contaminants and measure their fate and transport in the environment, including work related to polychlorinated biphenyls (PCBs), poly- and perfluoroalkyl substances (PFAS), and chlorinated volatile organic contaminants in the environment. Presenters include: Keri Hornbuckle, Ph.D., University of Iowa SRP Center; Jennifer Guelfo, Ph.D., Brown University SRP Center; and Mark Brusseau, Ph.D., University of Arizona SRP Center.

Issues and Options in Human Health Risk Assessment - A Resource When Alternatives to Default Parameters and Scenarios are Proposed

Interstate Technology Regulatory Council Many state and local regulatory agencies responsible for the cleanup of chemicals released to the environment have adopted regulations, guidance and policies that define default approaches, scenarios, and parameters as a starting point for risk assessment and the development of risk-based screening values. Regulatory project managers and decision makers, however, may not have specific guidance when alternative approaches, scenarios, and parameters are proposed for site-specific risk assessments, and are faced with difficult technical issues when evaluating these site-specific risk assessments. This ITRC web-based document is a resource for project managers and decision makers to help evaluate alternatives to risk assessment default approaches, scenarios and parameters.

ITRC's Decision Making at Contaminated Sites: Issues and Options in Human Health Risk Assessment (RISK-3, 2015) guidance document is different from existing ITRC Risk Assessment guidance and other state and federal resources because it identifies commonly encountered issues and discusses options in risk assessment when applying site-specific alternatives to defaults. In addition, the document includes links to resources and tools that provide even more detailed information on the specific issues and potential options. The ITRC Risk Assessment Team believes that state regulatory agencies and other organizations can use the RISK-3 document as a resource or reference to supplement their existing guidance. Community members and other stakeholders also may find this document helpful in understanding and using risk assessment information.

After participating in this ITRC training course, the learner will be able to apply ITRC's Decision Making at Contaminated Sites: Issues and Options in Human Health Risk (RISK-3, 2015) document when developing or reviewing site-specific risk assessments by:
  • Identifying common issues encountered when alternatives to default parameters and scenarios are proposed during the planning, data evaluation, toxicity, exposure assessment, and risk characterization and providing possible options for addressing these issues
  • Recognizing the value of proper planning and the role of stakeholders in the development and review of risk assessments
  • Providing information (that includes links to additional resources and tools) to support decision making when alternatives to default approaches, scenarios and parameters are proposed
ITRC offers additional documents and training on risk management. ITRC's Use of Risk Assessment in Management of Contaminated Sites (RISK-2, 2008) and associated Internet-based training archive highlight variation of risk-based site management and describes how to improve the use of risk assessment for making better risk management decisions. ITRC's Examination of Risk-Based Screening Values and Approaches of Selected States (RISK-1, 2005) and associated Internet-based training archive focus on the process by which risk-based levels are derived in different states.

Integrated DNAPL Site Characterization

Interstate Technology Regulatory Council Sites contaminated with dense nonaqueous phase liquids (DNAPLs) and DNAPL mixtures present significant environmental challenges. Despite the decades spent on characterizing and attempting to remediate DNAPL sites, substantial risk remains. Inadequate characterization of site geology as well as the distribution, characteristics, and behavior of contaminants -- by relying on traditional monitoring well methods rather than more innovative and integrated approaches -- has limited the success of many remediation efforts.

The Integrated DNAPL Site Characterization Team has synthesized the knowledge about DNAPL site characterization and remediation acquired over the past several decades, and has integrated that information into a new document, Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015). This guidance is a resource to inform regulators, responsible parties, other problem holders, consultants, community stakeholders, and other interested parties of the critical concepts related to characterization approaches and tools for collecting subsurface data at DNAPL sites. After this associated training, participants will be able to use the ITRC Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015) guidance to develop and support an integrated approach to DNAPL site characterization, including:
  • Identify what site conditions must be considered when developing an informative DNAPL conceptual site model (CSM)
  • Define an objectives-based DNAPL characterization strategy
  • Understand what tools and resources are available to improve the identification, collection, and evaluation of appropriate site characterization data
  • Navigate the DNAPL characterization tools table and select appropriate technologies to fill site-specific data gaps
For reference during the training class, participants should have a copy of Figure 4-1, the integrated site characterization flow diagram from the ITRC Technical and Regulatory Guidance document: Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015) and available as a PDF at http://www.cluin.org/conf/itrc/IDSC/ITRC-ISC-Figures.pdf
