“(ii) directly from the ambient air, and

“(B) is measured at the source of capture and verified at the point of disposal, injection, or utilization.

“(2) RECYCLED CARBON DIOXIDE.—The term ‘qualified carbon dioxide’ includes the initial deposit of captured carbon dioxide used as a tertiary injectant. Such term does not include carbon dioxide that is recaptured, recycled, and re-injected as part of the enhanced oil and natural gas recovery process.

“(1) the construction of which begins before January 1, 2024, and—

“(A) the original planning and design for such facility includes installation of carbon capture equipment, or

“(B) the construction of carbon capture equipment with respect to such facility begins before such date, and

“(2) which captures—

“(A) in the case of a facility which emits not more than 500,000 metric tons of carbon dioxide into the atmosphere during the taxable year, not less than 25,000 metric tons of qualified carbon dioxide during the taxable year which is utilized in a manner described in subsection (e)(7), or

“(B) in the case of a facility not described in subparagraph (A), not less than 100,000 metric tons of qualified carbon dioxide during the taxable year.

“(e) Special rules and other definitions.—For purposes of this section—
