    Audio for "ITRC: Reuse of Solid Mining Waste," Feb 13, 2025

    Solid mining waste represents a significant quantity of waste material in the United States and around the world. Solid mining waste has a range of physical and chemical properties that make it both potentially valuable and potentially hazardous to human health and the environment. From a commercial perspective, mining removes most of the primary minerals of interest; however, waste materials can still contain valuable minerals and other materials that can be recovered. The different types of mining sites and potential wastes for reuse provide a significant challenge but also an opportunity for innovation. Improvements in extraction and mineral processing technologies have occurred over time making it possible to recover minerals present in low concentrations. Interest in trace metals and rare earth elements (REEs) has increased, especially with the drive towards renewable energy sources increasing demand for key minerals required for solar panels and batteries. The reuse of solid mining waste can consist of reprocessing and repurposing the waste for resource recovery or a new application or product. This reuse serves as a solution to two significant needs:a domestic supply of minerals and materials for sustainable development and national defense purposesthe reclamation and remediation of land to reduce risks to human and environmental health The ITRC Reuse of Solid Mining Waste training and guidance document is geared towards state regulators and environmental consultants, mining and manufacturing stakeholders, community and tribal stakeholders, and other who have an interest in the potential reuse of solid mining waste. The guidance and this associated training course includes:Mining wastes introductionConsiderations for reusing mining waste: waste characterization, economic and market considerations, life cycle and risk assessment, regulatory considerations, & stakeholder considerationsPotential applications for the reuse of solid mining waste: examples of construction, environmental, and industrial reusesReview of technologies used in mineral beneficiation and processing Additionally, the guidance includes several case studies illustrating a range of current mining waste reuse scenarios. Prior to attending the training class, participants are encouraged to view the associated ITRC Reuse of Solid Mining Waste document.

    Audio for "1,4-Dioxane: Science, Characterization & Analysis, and Remediation," Feb 6, 2025

    In 2020, ITRC's 1,4-Dioxane team created multiple tools and documents that provide information to assist all interested stakeholders in understanding this contaminant and for making informed, educated decisions. Since the 1950s, 1,4-Dioxane has seen widespread use as a solvent stabilizer. The use of solvents through the 1980s suggests its presence at thousands of solvent sites in the US; however, it is not always a standard compound in typical analytical suites for hazardous waste sites, so it previously was overlooked. The U.S. EPA has classified 1,4-Dioxane as "likely to be carcinogenic to humans." Some states have devised health standards or regulatory guidelines for drinking water and groundwater standards; these are often sub-part per billion values. These low standards present challenges for analysis, characterization, and remediation of 1,4-Dioxane. The 1,4-Dioxane: Science, Characterization & Analysis, and Remediation training is a series of six (6) modules. The six individual modules will be presented together live, and then archived on the ITRC 1,4-Dioxane training webpage for on demand listening. The modular 1,4-Dioxane training series provides an overview of 1,4-Dioxane and presenting six sections from the ITRC guidance document (1,4d-1, 2021):History of Use and Potential Sources (Sect 1)Regulatory Framework (Sect 2)Fate and Transport (Sect 3)Sampling and Analysis (Sect 4)Toxicity and Risk Assessment (Sect 5)Remediation and Treatment Technologies (Sect 6)After the six-part 1,4-Dioxane: Science, Characterization & Analysis, and Remediation series, you should understand:The history of 1,4-Dioxane manufacturing and usage and the potential sources of releases of 1,4-Dioxane to the environment.Primary state and U.S. federal regulatory programs of relevance to 1,4-DioxaneKey physical/chemical properties, and fate and transport processes that are relevant for 1,4-DioxaneBenefits and limitations of the available analytical methodsRisk drivers for human health and how ecological risk comparesHow/when/why different treatment technologies are appropriate We encourage you to use the ITRC 1,4-Dioxane products (14d-1) and these training modules to learn about 1,4-Dioxane and how you can apply these best practices to improve decision-making at your sites. For regulators and other government agency staff, this understanding of 1,4-Dioxane can be incorporated into your own programs. This training summarizes the current understanding of 1,4-Dioxane. While the training makes every effort to keep the information accessible to a wide audience, it is assumed that the participants will have some basic technical understanding of chemistry, environmental sciences, and risk assessment. As with other emerging contaminants, our understanding of 1,4-Dioxane continues to advance. This training provides the participants with information on areas where the science is evolving and where uncertainty persists.

    Audio for "ITRC PFAS Introductory Training," Jan 28, 2025

    Per- and polyfluoroalkyl substances (PFAS) are a large and complex class of anthropogenic compounds whose prevalence in the environment are an emerging, worldwide priority in environmental and human health. The ITRC PFAS Team, formed in 2017, has prepared readily accessible materials to present PFAS information to stakeholders, regulators, and policy makers. The PFAS team represents a diverse cross-section of expertise and experience working on PFAS. This training will include emerging science on PFAS, including topics such as Properties of PFAS, Fate and Transport, Sampling and Analysis, and Treatment Technologies. The technical presentations will be focused on those who are relatively new to PFAS. The training will last approximately 90 minutes and include time for questions.

    Audio for "ITRC: Contaminants of Emerging Concern (CEC) Identification Framework," Jan 16, 2025

    In 2023, the ITRC Contaminants of Emerging Concern (CEC) Framework was published to help environmental regulatory agencies and other stakeholders identify, evaluate, and manage CEC's while acknowledging uncertainties in their environmental fate and transport, receptor exposure, and/or toxicity. Such an approach can be conducive to improved allocation of regulatory response resources and provide a foundation for communicating potential risk to stakeholders. The ITRC framework is comprised of a white paper and four associated fact sheets. In the white paper, CEC are defined as: "substances and microorganisms including physical, chemical, biological, or radiological materials known or anticipated in the environment, that may pose newly identified risks to human health or the environment." The framework is meant to help environmental regulatory agencies and other stakeholders by providing examples of CEC monitoring programs and guiding the user through the process of identifying CEC key characteristics, how to communicate real and perceived risk from CEC to the public, and how laboratory analytical methods can be used in the identification process.The ITRC CEC training presents this entirely new framework for identification, prioritization, and communication of CEC. This course includes the following topics:An overview of the framework, how and why it was developed, the factors that influence the creation of CEC management units at the state level, and a listing of existing CEC monitoring programs.A discussion of key variables that may be used as criteria to identify and prioritize CEC for response actions. This portion of the course includes a case study that illustrates how the identification and prioritization process works with an "unknown" chemical CEC.Practices and methods for stakeholder messaging and how to share incomplete information on CEC that could impact human health and the environment. This portion of the short course builds upon the ITRC Risk Communication Toolkit by providing additional detail addresses communications plans, message maps, and audience identification.A paradigm for how laboratory methods can be used to identify CEC ranging from: "Is compound X in the sample and at what concentration?" (i.e., known knowns) to"Which compounds from the list are in this sample?" (i.e., known unknowns) to"What is in the sample?" (i.e., unknown unknowns). CEC are typically compounds or substances whose occurrence or effect is unknown but may or may not be understood through similar compounds or substances. This module includes a discussion of the use of targeted and untargeted analysis to identify a CEC.Participants will learn the elements of the CEC framework and gain an understanding of the framework application from case studies. Participants are encouraged to review the ITRC CEC Framework prior to the class.

    Audio for "ITRC: Overview of the Tire-Derived Chemicals 6PPD & 6PPD-quinone," Jan 14, 2025

    In October 2024, ITRC released the 6PPD & 6PPD-quinone Guidance Document to provide environmental professionals and communities with information about the current science and regulatory framework of 6PPD and 6PPD-quinone (6PPD-q). 6PPD-q is a contaminant of emerging concern and is a transformation product of the tire anti-degradant (6PPD), an antiozonant used in tires. Join us for this ITRC training course to get a basic overview of the science and policy measures surrounding the Tire Anti-Degradants 6PPD and 6PPD-q. Attendees will gain insight into the current state of knowledge on topics such as: background and use of 6PPD in tires, toxicity in aquatic species and humans; occurrence, fate, and transport; measuring, mapping, and sampling; mitigation measures; and policy, regulations, and laws. Currently, 6PPD is used in all tires and can contaminate stormwater and surface water anywhere tires are used. 6PPD-q was identified as a chemical fatal to coho salmon in 2020. Since that time, it has been documented as acutely toxic to multiple trout species found throughout the United States. 6PPD and 6PPD-q have been found in waterways, aquatic organisms, soils, air, and humans. This training will introduce you to the ITRC 6PPD & 6PPD-quinone Guidance Document which provides more technical detail than can be covered in this training course To view this archive online or download the slides associated with this seminar, please visit http://www.clu-in.org/conf/itrc/6PPD-Q_011425/
