SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Air Quality Standard Improvement Act 
of 2000''.

SEC. 2. PURPOSES.

    The purposes of this Act are--
            (1) to establish more effective environmental standards to 
        continue to safeguard public health and the environment;
            (2) to promote better resource allocation to ensure that 
        serious risks to air quality are addressed first;
            (3) to improve the ability of the Administrator of the 
        Environmental Protection Agency to use scientific and economic 
        analysis in developing air quality standards;
            (4) to yield increased public health and environmental 
        benefits and more effective protections while minimizing costs;
            (5) to require that relevant qualitative and quantitative 
        information be considered in the process of evaluating the 
        costs and benefits of air quality standards;
            (6) to promote the right of the public to know about the 
        costs and benefits of air standards, the risks addressed, the 
        risks reduced, and the quality of scientific and economic 
        analysis used to support decisions; and
            (7) to require the Administrator of the Environmental 
        Protection Agency to conduct risk assessments and cost-benefit 
        analyses as part of the process of establishing a new or 
        revised air quality standard.

SEC. 3. RISK ASSESSMENT AND COST-BENEFIT ANALYSIS.

    The Clean Air Act (42 U.S.C. 7401 et seq.) is amended by adding at 
the end the following:

``SEC. 703. COST-BENEFIT ANALYSIS.

    ``(a) Definitions.--In this section:
            ``(1) Benefit.--The term `benefit' means the reasonably 
        identifiable significant favorable effects, quantifiable and 
        nonquantifiable, including social, health, safety, 
        environmental, and economic effects, that are expected to 
        result from implementation of, or compliance with, a new or 
revised air quality standard.
            ``(2) Cost.--The term `cost' means the reasonably 
        identifiable significant adverse effects, quantifiable and 
        nonquantifiable, including social, health, safety, 
        environmental, and economic effects, that are expected to 
        result from implementation of, or compliance with, a new or 
        revised air quality standard.
            ``(3) Cost-benefit analysis.--The term `cost-benefit 
        analysis' means an evaluation of the costs and benefits of a 
        new or revised air quality standard, quantified to the extent 
        feasible and appropriate and otherwise qualitatively described, 
        that is prepared in accordance with the requirements of this 
        section at the level of detail appropriate and practicable for 
reasoned decisionmaking on the matter involved, taking into 
consideration uncertainties, the significance and complexity of the 
decision, and the need to adequately inform the public.
    ``(b) Analysis.--For each new or revised air quality standard 
proposed, the Administrator--
            ``(1) shall conduct and publish, for public comment, a 
        cost-benefit analysis to determine whether the benefits of the 
        new or revised air quality standard justify, or do not justify, 
        the costs; and
            ``(2) may analyze the potential distributional effects of 
        the new or revised air quality standard.
    ``(c) Determination of Health Risk Reduction and Cost 
Considerations.--
            ``(1) Determination of no justification for cost.--
                    ``(A) In general.--Notwithstanding any other 
                provision of this Act, if the Administrator determines, 
                based on an analysis conducted under subsection (b), 
                that the benefits of a new or revised air quality 
                standard proposed or promulgated in accordance with 
                this Act do not justify the costs, the Administrator 
                may, after notice and opportunity for public comment, 
                promulgate an alternative new or revised air quality 
                standard at a cost that is justified by the benefits.
                    ``(B) Scope of consideration.--In making a 
                determination under subparagraph (A), the Administrator 
                shall consider--
                            ``(i) only public health benefits, with 
                        respect to a determination concerning a primary 
                        national ambient air quality standard; and
                            ``(ii) public health and environmental 
                        benefits, with respect to a determination 
                        concerning any air quality standard other than 
                        a national ambient air quality standard.
            ``(2) Judicial review.--A determination by the 
        Administrator under paragraph (1)--
                    ``(A) shall be reviewed by a court only as part of 
                a review of a final regulation that has been 
                promulgated based on the determination; and
                    ``(B) shall be set aside by a court if the court 
                finds that the determination is arbitrary and 
                capricious.
    ``(d) Authorization of Appropriations.--There are authorized to be 
appropriated such sums as are necessary to carry out this section.''.
Requires the Administrator to ensure that the presentation of information on public health effects concerning any new or revised air quality standard is comprehensive, informative, understandable, and available for public comment prior to the promulgation of any regulation under the Act.
Directs the Administrator, in a document made available to the public in support of a regulation proposed or promulgated under the Act concerning an air quality standard to specify: (1) each population addressed by any estimate of public health effects; (2) the expected risk or central estimate of risk for the specific populations or resources and each upper-bound or lower- bound of risk; (3) each significant uncertainty identified in the process of the assessment of public health effects and studies that would assist in resolving such uncertainties; and (4) peer-reviewed studies that support, are relevant to, or fail to support any estimate of public health effects and the methodologies used to reconcile inconsistencies in the scientific data.
Requires the Administrator, as part of the process of proposing a new or revised air quality standard, to publish in the Federal Register and seek public comment on an analysis of specified factors, including: (1) quantifiable and nonquantifiable benefits that are likely to occur as the result of actions taken to comply with the standard; (2) quantifiable and nonquantifiable health benefits that are likely to occur from reductions in related pollutants that may be attributed to compliance with the standard; (3) quantifiable and nonquantifiable costs that are likely to occur as the result of actions taken to comply with or attain the standard; (4) incremental costs and benefits associated with each alternative standard considered; (5) effects of the affected air pollutant on the general population; and (6) risks that may occur as the result of compliance with or attainment of the standard.
Authorizes appropriations.
Directs the Administrator, for each new or revised air quality standard proposed, to conduct and publish for public comment a cost-benefit analysis to determine whether the benefits of the standard justify or do not justify the costs. Authorizes the Administrator to analyze the potential distributional effects of each such standard. Permits the Administrator, upon determining based on such analysis that the benefits do not justify the costs, to promulgate an alternative standard at a cost that is justified by the benefits.
Authorizes appropriations.
