- ITRC: Reuse of Solid Mining Waste – Interstate Technology and Regulatory Council
September 3, 2026, 1:00PM-3:00PM EDT, 17:00-19:00 GMT
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 purposes
- the 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 introduction
- Considerations for reusing mining waste: waste characterization, economic and market considerations, life cycle and risk assessment, regulatory considerations, & stakeholder considerations
- Potential applications for the reuse of solid mining waste: examples of construction, environmental, and industrial reuses
- Review 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.

- ITRC: Contaminants of Emerging Concern (CEC) Identification Framework – Interstate Technology and Regulatory Council
October 1, 2026, 1:00PM-3:00PM EDT, 17:00-19:00 GMT
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.

- ITRC: Microplastics – Interstate Technology and Regulatory Council
October 8, 2026, 1:00PM-3:00PM EDT, 17:00-19:00 GMT
In response to one of the biggest emerging environmental concerns, ITRC formed the Microplastics Team in 2021 to develop the Microplastics Guidance Document. Plastics have become pervasive in modern life and are now used in a wide range of commercial and industrial applications. Microplastics may result from the degradation and fragmentation of larger plastics, or they may be intentionally produced for specific applications and products. Regardless of their origin, microplastics are now ubiquitous in our environment. Because of their small size and pervasiveness in the environment, microplastics, along with any other contaminants which are adhered to the microplastics, may be inadvertently consumed by humans and other organisms.
The online ITRC Guidance Document is geared toward an audience with reasonable level of scientific understanding, but not microplastic-specific knowledge. The guidance provides a user with information on microplastics and the state of the applied science without having to go to the scientific literature.
The target audience for the guidance and this training course includes state regulators and environmental consultants, as well as community and tribal stakeholders.
The guidance and this associated training course uses a conceptual site model to navigate microplastics in the environment and explore the following general areas:- An introduction to microplastics, their sources, and worldwide distribution
- The pathways through which microplastics can enter and travel in the environment and their distribution in various media (water, soil, sediment, air, and biota)
- A current look at the most common techniques and best practices for sampling and analyzing microplastics
- Potential human health and ecological risks associated with microplastics in the environment
- An overview of existing regulations related to microplastics and macroplastics at the state, federal, and international levels
- Examples of prevention and mitigation strategies and best management practices to reduce microplastics from entering the environment and the emerging technologies to abate, treat, and remediate microplastics once they exist in the environment
- Identification of data gaps and the need for further research
- Several case studies illustrating a range of current microplastics-related topics
Prior to attending the training class, participants are encouraged to view the associated ITRC Microplastics Guidance Document.
