SECTION 1. CREDIT FOR BIOMETHANE PRODUCED FROM BIOMASS WHICH IS 
              EQUIVALENT TO CREDIT FOR ELECTRICITY PRODUCED FROM 
              BIOMASS.

    (a) In General.--Subsection (e) of section 45 of the Internal 
Revenue Code of 1986 (relating to electricity produced from certain 
renewable resources, etc.) is amended by redesignating paragraphs (9), 
(10), and (11) as paragraphs (10), (11), and (12), respectively, and by 
inserting after paragraph (8) the following new paragraph:
            ``(9) Credit for biomethane produced from biomass which is 
        equivalent to credit for electricity produced from biomass.--
                    ``(A) Determination of credit amount.--In the case 
                of a producer of biomethane, the credit determined 
                under this section (without regard to this paragraph) 
                for any taxable year shall be increased by 1.5 cents 
                for each 3412 Btus of biomethane--
                            ``(i) produced by the taxpayer--
                                    ``(I) from biomass, and

                term `biomass' has the meaning given to such term by 
                section 45K(c)(3).
                    ``(C) Biomethane.--For purposes of this paragraph, 
                the term `biomethane' means gas produced from biomass 
                if the properties of such gas meet the requirements to 
                be transported in an interstate natural gas pipeline as 
                a natural gas substitute. Such term includes liquefied 
                gas which would be described in the preceding sentence 
                but for being in liquid form.
                    ``(D) Application of rules.--Rules similar to the

                January 1, 2008 (determined without regard to this 
                subparagraph), and which produced electricity from 
                methane--

                        biomethane if no credit was allowed under this 
                        section for electricity so produced and sold

is amended by adding at the end the following new paragraph:
            ``(11) Biomethane facility.--In the case of a facility 
        producing biomethane, the term `biomethane facility' means any 
        facility placed in service after December 31, 2007, and before

    (c) Coordination With Credit for Producing Fuel From a

                    ``(C) Biomethane facilities.--The term `biomethane 
                facility' shall not include any facility the production 
                from which is allowed as a credit under section 45K for 
                the taxable year or any prior taxable year (or under 
                section 29, as in effect on the day before the date of

Amends the Internal Revenue Code to: (1) allow a tax credit for the production of biomethane from biomass and make such credit amount equal to the tax credit for producing electricity from biomass; and (2) include biomethane facilities as qualified facilities for purposes of the tax credit for producing electricity from renewable resources.
To amend the Internal Revenue Code of 1986 to provide a credit against income tax for biomethane produced from biomass which is equivalent to the credit allowed for electricity produced from biomass.
