This bill, titled the "6PPD Task Force Act," mandates the establishment of a task force within 60 days by the Secretary of Transportation, in consultation with the Administrator of the Environmental Protection Agency and the National Academy of Sciences. The primary purpose of this 6PPD Task Force is to address the detrimental impacts of the chemical 6PPD and its degradation product, 6PPD-Q, on coho salmon and the broader environment. 6PPD is a common tire additive that, when it breaks down, forms 6PPD-Q, which is acutely toxic to aquatic species like coho salmon through stormwater runoff. The Task Force is charged with several key duties, including improving data sharing among federal agencies and research institutions, and identifying federal funding opportunities for research into 6PPD's impacts and the development of safer alternatives. It will also recommend strategies for expediting the identification, testing, and adoption of these alternatives, while sharing best practices for 6PPD mitigation efforts such as street sweeping and stormwater treatment. Furthermore, the Task Force will identify non-tire related exposure pathways for 6PPD and maintain an online repository of information and resources for various stakeholders. Its membership will comprise representatives from multiple federal agencies, Tribal governments, the private sector, environmental groups, state agencies, and university researchers, and it must submit annual reports to Congress detailing its findings and recommendations.
