Read twice and referred to the Committee on Environment and Public Works.
Sponsored by Jeff Merkley (D-OR)
What it does
This bill would establish a multi-agency task force, administered through the National Academy of Sciences, to study the chemical 6PPD — used in tires to prevent degradation — and its byproduct 6PPD-Q, which washes into waterways via stormwater runoff and is acutely toxic to coho salmon. The task force would coordinate data sharing among federal agencies, Tribal governments, states, and private industry; identify federal funding opportunities for research into safer alternatives; and publish annual reports with findings and recommendations to Congress. The task force would not have regulatory authority and would not mandate any changes to tire manufacturing.
Who benefits
Coho salmon populations and the ecosystems that depend on them. Pacific Northwest Tribal nations whose treaty fishing rights and cultural practices depend on salmon runs. Commercial and recreational salmon fishers. Researchers and universities studying aquatic toxicology who would gain access to coordinated funding and data. State and local governments with active 6PPD mitigation programs who would receive technical assistance and best practices. Tire and chemical manufacturers seeking a coordinated federal pathway to develop and commercialize safer alternatives. Communities relying on clean waterways for drinking water or recreation.
Who is hurt
Tire manufacturers and chemical additive suppliers who may face increased scrutiny and eventual pressure to reformulate products, even though the bill imposes no mandates. Taxpayers who would bear the cost of establishing and operating the task force and funding any recommended research grants. Competing research priorities may receive less federal attention or funding if resources are redirected toward 6PPD alternatives. Manufacturers of rubber products beyond tires — such as artificial turf, playground materials, and artificial reefs — could face future regulatory attention as the task force examines non-tire exposure pathways.
Supporters argue
Supporters argue that 6PPD-Q has been scientifically documented as acutely lethal to coho salmon — a species of significant ecological, economic, and cultural importance to Pacific Northwest Tribal nations and fishing communities — and that no coordinated federal response currently exists. They contend the bill takes a measured, evidence-first approach by directing research and coordination rather than imposing mandates, giving industry time to develop safe alternatives while ensuring passenger safety is not compromised. They further argue that the national security and domestic supply chain implications identified in the bill's findings make this a matter of broad federal interest, not merely a regional environmental concern.
Opponents argue
Opponents argue that the bill creates a new federal bureaucratic body to study a problem that state governments — particularly Washington and California — and private industry are already actively addressing, raising questions about duplication of effort and efficient use of federal resources. They contend that exempting the task force from the Federal Advisory Committee Act (FACA) removes standard transparency and public accountability requirements that normally govern federal advisory bodies, and that the bill's open-ended annual reporting structure could become a vehicle for future regulatory recommendations that go well beyond the bill's stated research scope.
