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 amounts under subparagraph (A) for any taxable year shall be determined as of the close of the taxable year.
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).
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.
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.
The term “reference price” means with respect to a calendar year the Secretary’s estimate of the annual average wellhead price per barrel for all domestic crude oil the price of which is not subject to regulation by the United States.
In the case of a property or facility in which more than 1 person has an interest, except to the extent provided in regulations prescribed by the Secretary, production from the property or facility (as the case may be) shall be allocated among such persons in proportion to their respective interests in the gross sales from such property or facility.
The amount of the credit allowable under subsection (a) shall be determined without regard to any production attributable to a property from which gas from Devonian shale, coal seams, geopressured brine, or a tight formation was produced in marketable quantities before January 1, 1980.
The term “barrel-of-oil equivalent” with respect to any fuel means that amount of such fuel which has a Btu content of 5.8 million; except that in the case of qualified fuels described in subparagraph (C) of subsection (c)(1), the Btu content shall be determined without regard to any material from a source not described in such subparagraph.
Persons shall be treated as related to each other if such persons would be treated as a single employer under the regulations prescribed under section 52(b). In the case of a corporation which is a member of an affiliated group of corporations filing a consolidated return, such corporation shall be treated as selling qualified fuels to an unrelated person if such fuels are sold to such a person by another member of such group.
Under regulations prescribed by the Secretary, rules similar to the rules of subsection (d) of section 52 shall apply.
Paragraph (1) shall not apply to any facility which produces coke or coke gas unless the original use of the facility commences with the taxpayer.
The amount of qualified fuels sold during any taxable year which may be taken into account by reason of this subsection with respect to any facility shall not exceed an average barrel-of-oil equivalent of 4,000 barrels per day. Days before the date the facility is placed in service shall not be taken into account in determining such average.
No credit shall be allowed with respect to any coke or coke gas which is produced using steel industry fuel (as defined in section 45(c)(7)) as feedstock if a credit is allowed to any taxpayer under section 45 with respect to the production of such steel industry fuel.
