(2) Applications To be eligible for a grant or contract under this subsection, an entity shall submit to the Secretary an application in such form, in such manner, and containing such agreements, assurances, and information as the Secretary determines necessary. (3) Reports Not later than 1 year after the date of enactment of this section, and annually thereafter for each of the following 4 years, the Secretary shall submit to Congress, and make publicly available, a report that provides an overview of the research conducted or supported under this section, together with any relevant findings. (4) Information sharing The Secretary shall share the findings of the research supported by grants and contracts under this subsection with— (A) the heads of relevant institutes and agencies of the Department of Health and Human Services (including the Director of the National Institute of Environmental Health Sciences and the Commissioner of Food and Drugs); (B) the Administrator of the Environmental Protection Agency; (C) the Director of the National Institute of Standards and Technology; (D) the Administrator of the National Oceanic and Atmospheric Administration; and (E) the centers of excellence for plastic exposure health research described in section 463C. (5) Authorization of appropriations There is authorized to be appropriated to carry out this subsection $10,000,000 for each of fiscal years 2026 through 2030. (c) Plastic exposure defined In this section, the term plastic exposure means exposure to macroplastics, microplastics, and nanoplastics, including through plastic production and manufacturing, occupational exposure, environmental exposure, end-user interaction (such as handling and use of food packaging, manufactured goods, and textiles), plastic recycling, plastic degradation through natural or human-made processes, and plastic waste and disposal. . (b) Centers of excellence for plastic exposure health research The Public Health Service Act is amended by inserting after section 463B ( 42 U.S.C. 285l–6 ) the following: 463C. Centers of excellence for plastic exposure health research (a) In general The Secretary, acting through the Director of the Institute (in this section referred to as the Secretary ) may award grants to, or enter into appropriate funding agreements with, public entities, nonprofit entities, academic research institutions, or consortia of such entities (including such consortia that collaborate with private entities) to pay all or part of the cost of planning, establishing, or strengthening, and providing basic operating support for, centers of excellence to conduct and improve the quality of scientific research to inform public health determinations and increase public awareness (where scientifically warranted) with respect to the potential health effects caused by plastic exposure. Such centers shall prioritize research that— (1) develops standard material definitions; (2) improves the quality of scientific results to fill gaps in the field of research; (3) fills gaps in the field of health research through the use of methods that improve the quality and comparability of scientific results; or (4) develops vetted testing methodologies for microplastics and nanoplastics that can be replicated and can be compared to other testing methodologies. (b) Purposes of centers The purposes of the centers of excellence referred to in subsection (a) are— (1) to improve the quality of scientific results while researching the potential health effects stemming from plastic exposure, including identifying potential links between plastic exposure and such potential health effects; (2) to identify potential exposures to plastic and conduct hazard assessments and risk assessments; and (3) to increase public awareness (where scientifically warranted) of— (A) the potential health effects of plastic exposure, sources of such exposure, outcomes of hazard assessments, and the results of risk assessments relating to such exposure; and (B) the research referred to in— (i) paragraph (1); or (ii) section 399V–8(a). (c) Use of funds Funds made available under this section may be used for— (1) the development of plastic hazard, exposure, or risk assessment methodologies that can be replicated and compared to other methodologies, which shall include— (A) the comprehensive characterization and methods for characterization of the chemical and physical properties of microplastics, nanoplastics, macroplastics, and other plastics; (B) the development of validated testing methodologies for microplastics and nanoplastics in different media that can be replicated and compared to other testing methodologies; and (C) detailing the quality assurance and quality control measures taken to improve the scientific results; (2) the application of exposure methodologies (including both new and existing methodologies), if appropriately validated and controlled, to assess the potential burden of plastic exposures; (3) the support of research to assess potential health impacts of plastic exposure; and (4) increasing public awareness of research results, as scientifically warranted. (d) Policies A grant or agreement under this section shall be entered into in accordance with policies established by the Secretary. (e) Duration of grant or agreement A grant or agreement under this section shall be for a period of 5 years, and may be renewed by the Secretary for subsequent 5-year periods in the case of a center of excellence for which an appropriate technical and scientific peer review group established by the Secretary has— (1) reviewed the operations of such center; and (2) submitted to the Secretary a recommendation that such grant or agreement be renewed.
