((a)) ** .—** The purpose of this section is to provide for the National Academies of Sciences, Engineering, and Medicine (in this section referred to as the “Academies”), an independent nonprofit scientific organization with appropriate expertise that is not part of the Federal Government, to review and evaluate the available scientific evidence regarding associations between diseases and toxic exposures.

((b)) ** .—**

((1)) The Secretary shall seek to enter into a five-year agreement with the Academies to perform the services covered by this section.

((2)) The Secretary shall seek to enter into an agreement described in paragraph (1) not later than 60 days after the date of the enactment of the Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act of 2022.

((3)) An agreement under this section may be extended in five-year increments.

((c)) ** .—** Under an agreement between the Secretary and the Academies under this section, the Academies shall review and summarize the scientific evidence, and assess the strength thereof, concerning the association between toxic exposures during active military, naval, air, or space service and each disease suspected to be associated with such exposure in the human population.

((d)) ** .—** For each disease reviewed under subsection (c), the Academies shall determine, to the extent that available scientific data permit meaningful determinations—

((1)) whether an association exists between toxic exposures and the occurrence of the disease, taking into account the strength of the scientific evidence and the appropriateness of the statistical and epidemiological methods used to detect the association;

((2)) the increased risk of the disease among those reporting toxic exposures during active military, naval, air, or space service;

((3)) whether there exists a plausible biological mechanism or other evidence of a positive association between the toxic exposure and the occurrence of the disease; and

((4)) determine the strength of evidence for a positive association based on categories furnished under .

((e)) ** .—** The head of each relevant Federal agency, including the Secretary of Defense, shall cooperate fully with the Academies in performing the services covered by this section.

((f)) ** .—**

((1)) Under an agreement between the Secretary and the Academies under this section, the Academies shall make any recommendations for additional scientific studies to resolve areas of continuing scientific uncertainty relating to toxic exposures.

((2)) In making recommendations under paragraph (1), the Academies shall consider—

((A)) the scientific information that is available at the time of the recommendation;

((B)) the value and relevance of the information that could result from additional studies; and

((C)) the cost and feasibility of carrying out such additional studies.

((g)) ** .—**

((1))

((A)) Under an agreement between the Secretary and the Academies under this section, not later than one year after the date of the enactment of the Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act of 2022, the Academies shall submit to the Secretary, the Committee on Veterans’ Affairs of the Senate, and the Committee on Veterans’ Affairs of the House of Representatives an initial report on the activities of the Academies under the agreement.

((B)) The report submitted under subparagraph (A) shall include the following:

((i)) The determinations described in subsection (d).

((ii)) A full explanation of the scientific evidence and reasoning that led to such determinations.

((iii)) Any recommendations of the Academies under subsection (f).

((2)) Under an agreement between the Secretary and the Academies under this section, not less frequently than once every two years after the date on which the initial report is submitted under paragraph (1)(A), the Academies shall submit to the Secretary, the Committee on Veterans’ Affairs of the Senate, and the Committee on Veterans’ Affairs of the House of Representatives an updated report on the activities of the Academies under the agreement.

((h)) ** .—**

((1)) If the Secretary is unable within the time period prescribed in subsection (b)(2) to enter into an agreement with the Academies for the purposes of this section on terms acceptable to the Secretary, the Secretary shall seek to enter into an agreement for the purposes of this section with another appropriate scientific organization that—

((A)) is not part of the Federal Government;

((B)) operates as a not-for-profit entity; and

((C)) has expertise and objectivity comparable to that of the Academies.

((2)) If the Secretary enters into an agreement with another organization as described in paragraph (1), any reference in this subchapter to the Academies shall be treated as a reference to the other organization.
