SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Corrosion Prevention Act of 2009''.

SEC. 2. CREDIT FOR CORROSION PREVENTION AND MITIGATION MEASURES FOR 
              ENERGY-RELATED PROPERTY.

    (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. 45R. CORROSION PREVENTION AND MITIGATION MEASURES FOR ENERGY-
              RELATED PROPERTY.

    ``(a) In General.--For purposes of section 38, the corrosion 
prevention and mitigation credit determined under this section for the 
taxable year is an amount equal to 50 percent of the excess of--
            ``(1) qualified corrosion prevention and mitigation 
        expenditures with respect to qualified energy-related property, 
        over
            ``(2) the amount such expenditures would have been, taking 
        into account--
                    ``(A) amounts paid or incurred to satisfy Federal, 
                State, or local requirements, and
                    ``(B) amounts paid for corrosion prevention 
                practices, as certified by a person certified pursuant 
                to subsection (b)(2).
    ``(b) Qualified Corrosion Prevention and Mitigation Expenditures.--
For purposes of this section--
            ``(1) In general.--The term `qualified corrosion prevention 
        and mitigation expenditures' means amounts paid or incurred by 
        the taxpayer during the taxable year for engineering design, 
        materials, and application and installation of corrosion 
        prevention and mitigation technology.
            ``(2) Certification may be required.--The Secretary shall 
        require by regulation that no amount be taken into account 
        under paragraph (1) for any design, material, application, or 
        installation unless such design, material, application, or 
        installation meets such certification requirements. Such 
        requirements shall provide for accreditation of certifying 
        persons by an independent entity with expertise in corrosion 
        prevention and mitigation technology.
            ``(3) Corrosion prevention and mitigation technology.--
        Corrosion prevention and mitigation technology includes a 
        system comprised of at least one of the following: a corrosion-
        protective coating or paint; chemical treatment; corrosion-
        resistant metals; and cathodic protection. The Secretary from 
        time to time by regulations or other guidance may modify the 
        list contained in the preceding sentence to reflect changes in 
        corrosion prevention and mitigation technology.
            ``(4) Qualified energy-related property.--The term 
        `qualified energy-related property' means property which is--
                    ``(A) comprised primarily of a metal susceptible to 
                corrosion,

    ``(c) Recapture of Credit.--
            ``(1) In general.--If, as of the close of any taxable year, 
        there is a recapture event with respect to any qualified

        such taxable year shall be increased by an amount equal to the 
        product of--

                prevention and mitigation expenditures of the taxpayer 
                with respect to such property had been zero.

Summary: Corrosion Prevention Act of 2009 - Amends the Internal Revenue Code to allow a two-year business-related tax credit for 50 of net expenditures for engineering design, materials, and application and installation of corrosion prevention and mitigation technology for energy-related property comprised primarily of metals susceptible to corrosion.
