For purposes of section 38, the nonconventional source production credit determined under this section for the taxable year is an amount equal to—

(1) $3, multiplied by

the barrel-of-oil equivalent of qualified fuels—

(A) sold by the taxpayer to an unrelated person during the taxable year, and

The amount of the credit allowable under subsection (a) shall be reduced by an amount which bears the same ratio to the amount of the credit (determined without regard to this paragraph) as—

(A) the amount by which the reference price for the calendar year in which the sale occurs exceeds $23.50, bears to

(B) $6.

(2) Credit and phaseout adjustment based on inflation The $3 amount in subsection (a) and the $23.50 and $6 amounts in paragraph (1) shall each be adjusted by multiplying such amount by the inflation adjustment factor for the calendar year in which the sale occurs. In the case of gas from a tight formation, the $3 amount in subsection (a) shall not be adjusted.

The amount of the credit allowable under subsection (a) with respect to any project for any taxable year (determined after the application of paragraphs (1) and (2)) shall be reduced by the amount which is the product of the amount so determined for such year and a fraction—

(A) In generalThe amount of the credit allowable under subsection (a) with respect to any project for any taxable year (determined after the application of paragraphs (1) and (2)) shall be reduced by the amount which is the product of the amount so determined for such year and a fraction— (i) the numerator of which is the sum, for the taxable year and all prior taxable years, of— (I) grants provided by the United States, a State, or a political subdivision of a State for use in connection with the project, (II) proceeds of any issue of State or local government obligations used to provide financing for the project the interest on which is exempt from tax under section 103, and (III) the aggregate amount of subsidized energy financing (within the meaning of section 48(a)(4)(C)) provided in connection with the project, and (ii) the denominator of which is the aggregate amount of additions to the capital account for the project for the taxable year and all prior taxable years.

(B) Amounts determined at close of year The amounts under subparagraph (A) for any taxable year shall be determined as of the close of the taxable year.

The amount allowable as a credit under subsection (a) with respect to any project for any taxable year (determined after the application of paragraphs (1), (2), and (3)) shall be reduced by the excess of—

(A) the aggregate amount allowed under section 38 for the taxable year or any prior taxable year by reason of the energy percentage with respect to property used in the project, over

(B) the aggregate amount recaptured with respect to the amount described in subparagraph (A)— (i) under section 49(b) or 50(a) for the taxable year or any prior taxable year, or (ii) under this paragraph for any prior taxable year.

(C) liquid, gaseous, or solid synthetic fuels produced from coal (including lignite), including such fuels when used as feedstocks.

The term “gas produced from a tight formation” shall only include gas from a tight formation—

(A) In general Except as provided in subparagraph (B), the determination of whether any gas is produced from geopressured brine, Devonian shale, coal seams, or a tight formation shall be made in accordance with section 503 of the Natural Gas Policy Act of 1978 (as in effect before the repeal of such section).

(B) Special rules for gas from tight formationsThe term “gas produced from a tight formation” shall only include gas from a tight formation— (i) which, as of April 20, 1977, was committed or dedicated to interstate commerce (as defined in section 2(18) of the Natural Gas Policy Act of 1978, as in effect on the date of the enactment of this clause), or (ii) which is produced from a well drilled after such date of enactment.

The term “biomass” means any organic material other than—

(A) oil and natural gas (or any product thereof), and

(B) coal (including lignite) or any product thereof.

For purposes of this section—

Sales shall be taken into account under this section only with respect to qualified fuels the production of which is within—

(A) the United States (within the meaning of section 638(1)), or

(B) a possession of the United States (within the meaning of section 638(2)).

The Secretary shall, not later than April 1 of each calendar year, determine and publish in the Federal Register the inflation adjustment factor and the reference price for the preceding calendar year in accordance with this paragraph.

(A) In general The Secretary shall, not later than April 1 of each calendar year, determine and publish in the Federal Register the inflation adjustment factor and the reference price for the preceding calendar year in accordance with this paragraph.

(B) Inflation adjustment factor The term “inflation adjustment factor” means, with respect to a calendar year, a fraction the numerator of which is the GNP implicit price deflator for the calendar year and the denominator of which is the GNP implicit price deflator for calendar year 1979. The term “GNP implicit price deflator” means the first revision of the implicit price deflator for the gross national product as computed and published by the Department of Commerce.
