        the assessed value of property for ad valorem taxation.
            (3) Commercial and industrial property.--The term

        (excluding pipeline property, public utility property, and land 
        used primarily for agricultural purposes or timber growth)

        property tax levy.
            (4) Pipeline property.--The term ``pipeline property'' 
        means all property, real, personal, and intangible, owned or 
        used by a natural gas pipeline providing transportation or 
        storage of natural gas, subject to the jurisdiction of the

        property'' means property (excluding pipeline property) that is 
        devoted to public service and is owned or used by any entity

    (b) Discriminatory Acts.--The acts specified in this subsection

State, subdivision of a State, authority acting for a State or 
subdivision of a State, or any other taxing authority (including a 
taxing jurisdiction and a taxing district) may not do any of the 
following such acts:
            (1) Assess pipeline property at a value that has a higher 
        ratio to the true market value of the pipeline property than 
        the ratio that the assessed value of other commercial and 
        industrial property in the same assessment jurisdiction has to 
        the true market value of the other commercial and industrial 
        property.
            (2) Levy or collect a tax on an assessment that may not be 
        made under paragraph (1).
            (3) Levy or collect an ad valorem property tax on pipeline 
        property at a tax rate that exceeds the tax rate applicable to 
        commercial and industrial property in the same assessment 
        jurisdiction.
            (4) Impose any other tax that discriminates against a 
        pipeline providing transportation subject to the jurisdiction 
        of the Federal Energy Regulatory Commission.
    (c) Jurisdiction of Courts; Relief.--
            (1) Grant of jurisdiction.--Notwithstanding section 1341 of 
        title 28, United States Code, and notions of comity, and 
        without regard to the amount in controversy or citizenship of

        authorities and taxing jurisdictions, to prevent a violation of 
        subsection (b).
            (2) Relief.--Except as otherwise provided in this 
        paragraph, relief may be granted under this Act only if the 
        ratio of assessed value to true market value of pipeline 
        property exceeds by at least 5 percent the ratio of assessed 
        value to true market value of other commercial and industrial 
        property in the same assessment jurisdiction. If the ratio of 
        the assessed value of other commercial and industrial property 
        in the assessment jurisdiction to the true market value of all 
        other commercial and industrial property cannot be determined 
        to the satisfaction of the court through the random-sampling 
        method known as a sales assessment ratio study (to be carried 
        out under statistical principles applicable to such a study), 
        each of the following shall be a violation of subsection (b) 
        for which relief under this section may be granted:
                    (A) An assessment of the pipeline property at a 
                value that has a higher ratio of assessed value to the 
                true market value of the pipeline property than the 
                ratio of the assessed value of all other property 
                (excluding public utility property) subject to a 
                property tax levy in the assessment jurisdiction has to 
                the true market value of all other property (excluding 
                public utility property).
                    (B) The collection of an ad valorem property tax on 
                the pipeline property at a tax rate that exceeds the 
                tax rate applicable to all other taxable property 
                (excluding public utility property) in the taxing 
                jurisdiction.

SEC. 3. NATURAL GAS PIPELINE INTEGRITY REASSESSMENT INTERVALS BASED ON 
              RISK.

    (a) In General.--Section 60109(c)(3)(B) of title 49, United States 
Code, is amended by inserting ``, until the Secretary issues 
regulations basing the reassessment intervals on technical data, risk 
factors, and engineering analysis, consistent with the recommendations 
of the Comptroller General of the United States in Report 06-945'' 
after ``subparagraph (A)''.
    (b) Effective Date.--The amendment made by this section shall take 
effect on the date of the enactment of this Act.

Summary: Amends the Internal Revenue Code to: (1) modify tax-exempt bond financing rules to exclude from the private business use and private loan financing tests certain property used to transmit electricity or carbon dioxide or to transport crude oil and other petroleum products. And (2) reduce the state volume cap for tax-exempt bonds by the amount of bonds issued for such property. Describes the following as acts that unreasonably burden and discriminate against interstate commerce, and prohibits states, political subdivisions, and any other taxing authority from: (1) assessing natural gas pipeline property at a value that has a higher ratio to its true market value than the ratio used to assess other commercial and industrial property in the same assessment jurisdiction, (2) levying or collecting a tax on such an assessment. (3) levying or collecting an ad valorem property tax on natural gas pipeline property at a rate that exceeds the rate applicable to commercial and industrial property in the same assessment jurisdiction. Or (4) imposing any other tax that discriminates against a natural gas pipeline providing transportation subject to the jurisdiction of the Federal Energy Regulatory Commission. Grants jurisdiction to US District Courts and provides specified relief for claims of discriminatory taxation of natural gas pipeline property. Amends federal transportation law to modify the criteria for natural gas pipeline integrity reassessments to require the Secretary of Transportation to issue regulations basing the intervals for reassessments on certain technical data, risk factors, and engineering analysis.
