                and
                    (D) to designate the qualifying crypto-asset mining 
                operations source category established pursuant to 
                subparagraph (B) as a source category that is subject 
                to greenhouse gas reporting requirements and related 
                monitoring, recordkeeping, and reporting requirements 
                under section 98.2 of that title, regardless of whether 
                a qualifying crypto-asset mining operation emits at 
                least 25,000 metric tons of carbon dioxide-equivalent.
            (2) Final rule.--Not later than 180 days after the date on 
        which the public comment period on the proposed rule under

conducting an assessment of, with respect to qualifying crypto-asset 
mining operations, the permit programs under the Clean Air Act (42 
U.S.C. 7401 et seq.), which shall include identifying the extent to 
which any qualifying crypto-asset mining operations are improperly 
operating without a valid and current permit under that Act.
    (c) Authorization of Appropriations.--There is authorized to be 
appropriated to the Administrator to carry out this section $5,000,000
