A bill to amend the Internal Revenue Code of 1986 to extend the financing for Superfund for purposes of cleanup activities with respect to those Superfund sites for which removal and remedial action is estimated to cost more than $50,000,000, and for other purposes.

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Superfund Equity and Megasite 
Remediation Act of 2007''.

SEC. 2. FINDINGS.

    The Congress finds the following:
            (1) The Comprehensive Environmental Response, Compensation, 
        and Liability Act of 1980 established a Federal Superfund trust 
        fund for the purpose of hazardous substance removal and 
        remediation at sites across the Nation.
            (2) The release of hazardous substances may threaten and 
        impair public health, the local environment, community 
        infrastructure, the economy, and social well being.
            (3) The Environmental Protection Agency has evaluated more 
        than 45,000 sites and has currently listed 1,086 non-Federal 
        sites on the National Priorities List.
            (4) One in 4 Americans lives within 3 miles of a Superfund 
        site.
            (5) The expiration of the Superfund crude oil, chemical 
        feedstock, and corporate taxes in 1995 has contributed to a 
        funding shortfall and has shifted the burden of cleanup to the 
        general public, which has prevented numerous Superfund sites 
        from receiving new construction funding in fiscal years 2004, 
        2005, and 2006 and slowed the pace of existing cleanups.
            (6) Delayed and slowed Superfund cleanup actions magnify 
        public health risks and increase total remediation costs.
            (7) Responsible parties or potentially responsible parties 
        would continue to be liable for hazardous releases under the 
        Comprehensive Environmental Response, Compensation, and 
        Liability Act of 1980 after reestablishment of Superfund taxes.
            (8) Although costs vary from site to site, costs at some 
        sites are substantial and place a greater demand on the 
        Hazardous Substance Superfund resources to clean up 
        contamination.
            (9) The Environmental Protection Agency generally considers 
        Superfund sites where cleanup costs exceed $50,000,000 to be 
        megasites.
            (10) Megasites typically are among the larger, more 
        complex, and more severely contaminated of sites, presenting 
        the greatest cleanup challenges. As such, megasites are a 
        substantial factor driving future funding needs to clean up 
        hazardous substances under the Superfund program.
            (11) The Environmental Protection Agency commits a large 
        percentage of annual Superfund obligations for long-term 
        ongoing cleanup work at only a few sites. These megasites 
        siphon funding from other Superfund sites and result in 
        construction delays. In fiscal year 2006, 45 percent of funds 
        for Superfund construction and post-construction activities 
        went to only 14 sites.
            (12) As more megasites move beyond the analysis and design 
        phase into actual construction, funding needs for these sites 
        will increase. The average annual cost per megasite is 
        projected to be at least $140,000,000.
            (13) Megasites differ from non-megasites in that they 
        require more resources over the long term to address 
        complexities associated with developing remedies and cleaning 
        up contamination that can cover many square miles and may 
        involve multiple communities, responsible parties, Indian 
        Tribes, or States.
            (14) For some megasites there is no ascertainable final 
        remedy because remediation may involve decades of sequential 
        actions, and institutional controls may be required in 
        perpetuity. According to the Environmental Protection Agency, 
        more than half of the mining sites currently listed on the 
        National Priorities List will require operation and maintenance 
        in perpetuity.
            (15) Responsible parties may not be able to fund megasite 
        remediation activities that are anticipated to last for decades 
        or longer. The lack of a dedicated revenue stream raises 
        serious concerns about how a remediation program expected to 
        last for decades, if not centuries, can be successfully 
        implemented.
            (16) At megasites with no viable responsible parties, the 
        Federal Government pays 90 percent of the construction costs, 
        with the State paying the other 10 percent. Once construction 
        is completed, the State is solely responsible for paying all 
        operation and maintenance costs, a time frame that for many 
        megasites may extend in perpetuity.

        of that quarter, the unobligated balance in the Hazardous 
        Substance Superfund is less than $5,700,000,000.
            ``(2) No tax if unobligated balance in fund exceeds 
        $5,700,000,000.--The Hazardous Substance Superfund financing 
        rate shall not apply during a calendar quarter if the Secretary 
        estimates that, as of the close of the preceding calendar

            ``(2) No tax if unobligated balance in fund exceeds 
        $5,700,000,000.--The tax imposed by this section shall not 
        apply during a calendar quarter if the Secretary estimates 
        that, as of the close of the preceding calendar quarter, the 
        unobligated balance in the Hazardous Substance Superfund 
        exceeds $5,700,000,000.''.

            (2) the Administrator has designated as presenting high 
        health risks, including sites where hazardous substance 
        exposure to humans remains uncontrolled,
until such time as the Administrator determines by rule that no 
response actions are necessary to protect human health and the

under this section, the Administrator shall notify the Congress of the 
intention to initiate the rulemaking.

SEC. 5. ANNUAL REPORTS TO CONGRESS.

funded by the Hazardous Substance Superfund with respect to each non-
Federal site placed on the National Priorities List.
    (b) Contents of Report.--Each such report shall include, with 
respect to response actions at each site, the following:
    (1) A statement of the number of sites at which a hazardous 
substance has been identified.
    (2) A statement of the status of response actions proposed for or 
initiated at each site.
    (3) A statement of the total cost estimated for such response 
actions at each site.
    (4) A statement of the amount of funds obligated by the 
Administrator for such response actions at each site, and the progress 
made in implementing the response actions at each site during the 
fiscal year preceding the year in which the report is submitted, 
including an explanation of--
            (A) any cost overruns for such response actions, if the 
        amount of funds obligated for those response actions exceeds 
        the estimated cost for those response actions by the greater of 
        15 percent of the estimated cost or $10,000,000; and
            (B) any deviation in the schedule of more than 180 days for 
        such response actions at each site.
    (5) A statement of the amount of funds allocated by the 
Administrator for, and the anticipated progress in implementing, such 
response actions during the fiscal year in which the report is 
submitted.
    (6) A statement of the amount of funds requested for such response 
actions for the 5 fiscal years following the fiscal year in which the 
report is submitted, and the anticipated progress in implementing such

Summary: Superfund Equity and Megasite Remediation Act of 2007 - Amends the Internal Revenue Code to reinstate the Hazardous Substance Superfund financing rate and the corporate environmental income tax, except in certain calendar quarters in which the unobligated balance in the Hazardous Substance Superfund exceeds $5.7 billion. Provides for a 50 increase in the Hazardous Substance Superfund financing rate and the corporate environmental income tax between 2008 and 2013 to fund response actions at Superfund sites estimated to cost more than $50 million (megasites) or which pose high health risks. Establishes the Megasites and High Risk Sites Cleanup Account in the Hazardous Substance Superfund. Transfers to such Account revenues resulting from the temporary 50 increase in the Hazardous Substance Superfund financing rate and the corporate environmental income tax. Requires the Administrator of the Environmental Protection Agency (EPA) to report to Congress annually on the progress of response actions funded by the Hazardous Substance Superfund.
