    (a) In General.--Subpart D of part IV of subchapter A of chapter 1 
of the Internal Revenue Code of 1986 (relating to business related 
credits) is amended by adding at the end the following new section:

``SEC. 45G. ENVIRONMENTAL REMEDIATION CREDIT.

    ``(a) In General.--For purposes of section 38, the environmental 
remediation credit determined under this section is 50 percent of the 
qualified remediation expenditures paid or incurred by the taxpayer 
during the taxable year with respect to a qualified contaminated site 
located in an eligible area.
    ``(b) Qualified Remediation Expenditures.--For purposes of this 
section, the term `qualified remediation expenditures' means 
expenditures, whether or not chargeable to capital account, in 
connection with--
            ``(1) the abatement or control of any hazardous substance 
        (as defined in section 198(d)), petroleum, or any petroleum by-
        product at the qualified contaminated site in accordance with 
        an approved remediation and redevelopment plan,
            ``(2) the complete demolition of any structure on such site 
        if any portion of such structure is demolished in connection 
        with such abatement or control,

        with the activities described in paragraphs (1) and (2), and
            ``(4) the reconstruction of utilities in connection with 
        such activities.
For purposes of this section, the term `approved remediation and 
redevelopment plan' means any plan for such abatement, control, and 
redevelopment of a qualified contaminated site which is approved by the 
State development agency for the State in which the qualified 
contaminated site is located.
    ``(c) Credit May Not Exceed Allocation.--
            ``(1) In general.--The environmental remediation credit 
        determined under this section with respect to any qualified 
        contaminated site shall not exceed the credit amount allocated 
        under this section by the State development agency to the 
        taxpayer for the remediation and redevelopment plan submitted 
        by the taxpayer with respect to such site.
            ``(2) Time for making allocation.--An allocation shall be 
        taken into account under paragraph (1) for any taxable year 
        only if made before the close of the calendar year in which 
        such taxable year begins.
            ``(3) Manner of allocation.--
                    ``(A) Allocation must be pursuant to plan.--No 
                amount may be allocated under this subsection to any 
                qualified contaminated site unless such amount is 
                allocated pursuant to a qualified allocation plan of 
                the State development agency of the State in which such 
                site is located.
                    ``(B) Qualified allocation plan.--For purposes of 
                this paragraph, the term `qualified allocation plan' 
                means any plan--
                            ``(i) which sets forth selection criteria 
                        to be used to determine priorities of the State 
                        development agency in allocating credit amounts 
                        under this section, and
                            ``(ii) which gives preference in allocating 
                        credit amounts under this section to qualified

                                redevelopment.
            ``(4) States may impose other conditions.--Nothing in this 
        section shall be construed to prevent any State from requiring 
        assurances, including bonding, that any project for which a 
        credit amount is allocated under this section will be properly 
        completed or that the financial commitments of the taxpayer are 
        actually carried out.
    ``(d) State Environmental Remediation Credit Ceiling.--
            ``(1) In general.--The State environmental remediation 
        credit ceiling applicable to any State for any calendar year 
        shall be an amount equal to the sum of--

        is the excess (if any) of the sum of the amounts described in 
        subparagraphs (B), (C), and (D) over the aggregate 
        environmental remediation credit amount allocated for such 
        year.

        determines that the environmental remediation which is part of 
        the approved remediation and redevelopment plan for such site 
        was not properly completed, then the taxpayer's tax under this 
        chapter for the taxable year in which such determination is 
        made shall be increased by the credit recapture amount.

        this section.

                taxable year for qualified remediation expenditures

        under section 45G(a).''.
    (c) No Carrybacks Before Effective Date.--Subsection (d) of section 
39 of such Code (relating to carryback and carryforward of unused 
credits) is amended by adding at the end the following:
            ``(11) No carryback of section 45g credit before effective 
        date.--No portion of the unused business credit for any taxable 
        year which is attributable to the environmental remediation 
        credit determined under section 45G may be carried back to a 
        taxable year ending before the date of the enactment of section 
        45G.''.
    (d) Conforming Amendment.--The table of sections for subpart D of 
part IV of subchapter A of chapter 1 of such Code is amended by adding 
at the end the following new item:

                                        credit.''.
    (e) Effective Date.--The amendments made by this section shall 
apply to taxable years beginning after the date of the enactment of 
this Act.
Brownfields Revitalization Act of 2004 - Amends the Internal Revenue Code to allow a business tax credit for up to 50 percent of qualified remediation expenditures for contaminated sites (property used in a trade or business on which there has been a release (or threat of release) or disposal of any hazardous substance) in certain poverty-rated areas. Defines "qualified remediation expenditures" as expenditures for: (1) the abatement or control of any hazardous substance, petroleum, or any petroleum by-product at a contaminated site in accordance with a State-approved remediation and redevelopment plan; (2) the complete demolition of a structure; (3) the removal and disposal of property; and (4) the reconstruction of utilities on a contaminated site.

Requires States to allocate credit amounts under an allocation plan that considers specified criteria, including: (1) poverty rates: (2) location of a contaminated site; and (3) the amount of new employment expected to result from redevelopment. Imposes a ceiling on the State environmental remediation credit and limits the national environmental remediation credit for each calendar year to $1 billion. Sets forth special rules for: (1) allocating unused environmental remediation credit carryover amounts among States: (2) adjusting the limitation on the national environmental remediation credit for inflation; (3) assigning portions of the credit; and (4) recapturing credit amounts if a taxpayer fails to properly complete environmental remediation under a State approved remediation and redevelopment plan.
A bill to amend the internal Revenue Code of 1986 to allow taxpayers a credit against income tax for expenditures to remediate contaminated sites.
