EPA’s Trash Free Waters (TFW) program announces the publication of “Where the Rubber Meets the Road: Opportunities to Address Tire Wear Particles in Waterways.” Tire wear particles as a pollutant in waterways is a relatively new field of study without standardized terminology, assessment methodologies, or established solutions. The emergence of tire wear particles as a significant category of microplastics found in waterways prompted EPA to convene stakeholders in two roundtable discussions in Spring 2022 to facilitate shared learning about the challenges of addressing the problem of tire wear particle pollution. Stakeholders represented diverse perspectives on the nature of the problem and how to effectively address it. The roundtables provided a forum for discussion among participants without committing to a specific course of action. Participants discussed a set of questions aimed at understanding the barriers to and opportunities for managing tire wear particles in waterways. This brief report summarizes the roundtable discussions. In producing it, EPA seeks to share the challenges and potential solutions discussed during the roundtables, in order to inform the public and broaden the community engaged in addressing tire wear particle pollution.
