Ms. Strickland (for herself, Ms. Randall, and Ms. Salinas) introduced the following bill; which was referred to the Committee on Science, Space, and Technology, and in addition to the Committees on Transportation and Infrastructure, Energy and Commerce, and Natural Resources, for a period to be subsequently determined by the Speaker, in each case for consideration of such provisions as fall within the jurisdiction of the committee concerned
To establish a task force to address the impacts of the chemical 6PPD and its by-product 6PPD-Q on coho salmon and the environment and to promote research and funding opportunities for an alternative to the chemical 6PPD, and for other purposes.
Section 1. Short title
This Act may be cited as the 6PPD Task Force Act
.
Sec. 2. Findings
Congress finds the following:
(1)
6PPD is defined as the chemical compound N-(1,3-dimethylbutyl)-N'- 11 phenyl-p-phenylenediamine.
(2)
6PPD is a chemical commonly used in all motor vehicle tires, military vehicle tires, and aircraft tires, contributing to passenger safety by preventing tires from degrading quickly and ensuring their durability.
(3)
As 6PPD in tires reacts with oxygen or ozone in the environment, it breaks down and transforms into compounds, including 6PPD- Stormwater runoff may cause tire and road wear particles containing 6PPD-Q to wash into streams, rivers, and other bodies of water that are habitats for aquatic species, such as Pacific salmon.
(4)
6PPD-from stormwater runoff is acutely toxic to adult and juvenile coho salmon (Oncorhynchus kisutch).
(5)
Private-sector efforts in the United States exist to develop potential alternatives to 6PPD that will not transform into 6PPD-and enter into waterways, leading to coho salmon mortality, and will not harm other wildlife species or people, while also prioritizing motor vehicle passenger safety and environmental impacts.
(6)
Finding a 6PPD alternative has national security, domestic supply chain, and environmental and human health implications and must be addressed in a timely manner.
(7)
Efforts to replace 6PPD must ensure continued compliance with vehicle safety and performance standards critical to passenger and public safety.
Sec. 3. Establishment of 6PPD Task force
(a) Establishment
Not later than 60 days after the date of the enactment of this Act, the Secretary of Transportation, in consultation with the Administrator of the Environmental Protection Agency, shall, to the extent practicable, enter into an agreement with the National Academy of Sciences through which the Academy shall establish a task force to be known as the 6PPD Task Force
(in this Act referred to as the Task Force
).
(b) Duties
The Task Force shall—
(1)
improve data and information sharing for research into an alternative to 6PPD among Federal agencies, research institutions, and State, Tribal, and local governments for the purpose of—
(A)
identifying the potential impacts of 6PPD on coho salmon, other aquatic species, human health, and the environment; and
(B)
mitigating the adverse effects of 6PPD on water quality, human health, and the environment;
(2)
identify and recommend Federal funding opportunities to researchers, institutions of higher education, State governments, Tribal governments, local governments, tire manufacturers, chemical suppliers, tire additive manufacturers, and other entities to—
(A)
study the potential impacts of 6PPD, related compounds, and their degradation products, including 6PPD-, on Pacific salmon, other economically or ecologically valuable aquatic species, and human health; and
(B)
develop an alternative chemical to 6PPD, including scientific validation and scale-up activities to commercialize 6PPD alternatives;
(3)
identify and provide—
(A)
recommendations for expediting the identification, toxicity, and performance testing of safer alternatives to 6PPD; and
(B)
opportunities to encourage the adoption of safer alternatives to 6PPD in tires available on the market;
(4)
share with Federal agencies, research institutions, and State, Tribal, and local governments best practices, techniques, methodologies, and cost estimates for 6PPD mitigation efforts, including street sweeping and stormwater runoff treatment;
(5)
identify and provide research to Federal agencies, research institutions, and State, Tribal, and local governments regarding pathways not related to motor vehicle tires through which 6PPD exposure occurs, including exposure to 6PPD through—
(A)
reuse of tires, including artificial turf;
(B)
playground materials;
(C)
artificial reefs;
(D)
underwater tire piles; and
(E)
other rubber materials; and
(6)
share funding information, technical assistance, yearly reports, and resources in an online repository accessible to—
(A)
Tribes;
(B)
State departments of transportation;
(C)
metropolitan planning organizations;
(D)
State and local governments;
(E)
tire manufacturers;
(F)
chemical suppliers;
(G)
tire additive manufacturers;
(H)
institutions of higher education; and
(I)
the public.
(c) Membership
The Task Force shall be composed of the following members:
(1)
A designee of the Secretary of Transportation.
(2)
A designee of the Administrator of the Environmental Protection Agency.
(3)
A designee of the Secretary of Agriculture.
(4)
A designee of the Director of the United States Geological Survey.
(5)

(6)
A designee of the Administrator of the National Oceanic and Atmospheric Administration.
(7)
A designee of the Director of the National Institutes of Health.
(8)
A designee of the Director of the Centers for Disease Control and Prevention.
(9)

(10)
Not less than four representatives from the private sector appointed by the National Academy of Sciences, including—
(A)
two representatives from the tire manufacturing industry; and
(B)
two representatives from the tire chemical additive manufacturing industry.
(11)
Not less than one representative from the environmental community appointed by the National Academy of Sciences.
(12)
Not less than two representatives, at least two of whom should be from different States, with expertise in environmental and public health from State government agencies with active 6PPD mitigation programs or that have documented 6PPD runoff impacts on aquatic species appointed by the National Academy of Sciences.
