GAO reviewed the Environmental Protection Agency's (EPA) new rule on national ambient air quality standards (NAAQS) for ozone. GAO found that (1) the EPA's final rule revises the primary and secondary NAAQS for O3 to provide requisite protection of public health and welfare; and (2) the EPA complied with applicable requirements in promulgating the rule.

Environmental Protection Agency: National Ambient Air Quality Standards for Ozone, GAO-08-629R, April 10, 2008 B-316213 April 10, 2008 The Honorable Barbara Boxer Chairman The Honorable James M. Inhofe Ranking Minority Member Committee on Environment and Public WorksUnited States Senate The Honorable John D. Dingell Chairman The Honorable Joe Barton Ranking Minority Member Committee on Energy and Commerce House of Representatives Subject: Environmental Protection Agency: National Ambient Air Quality Standards for Ozone Pursuant to section 801(a)(2)(A) of title 5, United States Code, this is our report on a major rule promulgated by the Environmental Protection Agency (EPA), entitled –National Ambient Air Quality Standards for Ozone— (RIN: 2060-AN24). We received the rule on March 17, 2008. It was published in the Federal Register as a final rule on March 27, 2008. 73 Fed. Reg. 16,436. Based on its review of the air quality criteria for ozone (O3) and related photochemical oxidants and natural ambient air quality standards (NAAQS) for O3, EPA's final rule revises the primary and secondary NAAQS for O3 to provide requisite protection of public health and welfare. With regard to the primary standard for O3, EPA revised the level of the 8-hour standard to 0.075 parts per million (ppm), expressed to three decimal places. With regard to the secondary standard for O3, EPA revised the current 8-hour standard by making it identical to the revised primary standard. EPA also made conforming changes to the Air Quality Index (AQI) for O3, setting an AQI value of 100 equal to 0.075 ppm, 8-hour average, and making proportional changes to the AQI values of 50, 150, and 200. The final rule is effective on May 27, 2008. Enclosed is our assessment of the EPA's compliance with the procedural steps required by section 801(a)(1)(B)(i) through (iv) of title 5 with respect to the rule. Our review indicates that the EPA complied with the applicable requirements.

Volpe, Assistant General Counsel, at (202) 512-8236. signed Robert J. Cramer Associate General Counsel Enclosure cc: Nicole Owens Director, Regulatory Management Division Environmental Protection Agency ENCLOSURE REPORT UNDER 5 U.S.C. sect. 801(a)(2)(A) ON A MAJOR RULE ISSUED BY THE ENVIRONMENTAL PROTECTION AGENCY ENTITLED "NATIONAL AMBIENT AIR QUALITY STANDARDS FOR OZONE" (RIN: 2060-AN24) (i) Cost-benefit analysis EPA prepared a regulatory impact analysis (cost-benefit analysis) that estimated the costs and monetized human health and welfare benefits of attaining three alternative O3 NAAQS nationwide. The analysis examined the alternatives of 0.079 ppm, 0.075 ppm, 0.070 ppm, and 0.065 ppm. The analysis considered a limited number of emissions control scenarios that states and Regional Planning Organizations might implement to achieve these alternative O3 NAAQS. However, the Clean Air Act and judicial decisions make clear that the economic and technical feasibility of attaining ambient standards are not to be considered in setting or revising NAAQS, although such factors may be considered in the development of state plans to implement the standards. For this reason, EPA stated that although a cost-benefit analysis was prepared, the results of the analysis were not considered in the final rule. (ii) Agency actions relevant to the Regulatory Flexibility Act, 5 U.S.C. sections 603-605, 607, and 609 EPA certified that the final rule will not have a direct –significant economic impact on a substantial number of small entities.— Therefore, EPA did not prepare a regulatory flexibility analysis. (iii) Agency actions relevant to sections 202-205 of the Unfunded Mandates Reform Act of 1995, 2 U.S.C. sections 1532-1535 EPA certified that the final rule does not contain either an intergovernmental or private sector mandate, as defined in Title II, of more than $100 million (currently adjusted for inflation to $122 million) in any one year. (iv) Other relevant information or requirements under acts and executive orders Administrative Procedure Act, 5 U.S.C. sections 551 et seq. The final rule was issued using the notice and comment procedures contained in 5 U.S.C. sect. 553. On July 11, 2007, EPA published a Notice of Proposed Rulemaking in the Federal Register. 72 Fed. Reg. 37,818. (The schedule for completion of this rulemaking is governed by a consent decree resolving a lawsuit filed in March 2003 by a group of plaintiffs representing national environmental and public health organizations, alleging that EPA had failed to complete this final rule within the period provided by statute. The modified consent decree that currently governs this rulemaking provides that EPA sign for publication notices of proposed and final rulemaking concerning its review of the O3 NAAQS no later than June 20, 2007, and March 12, 2008, respectively.) EPA received a large number of comments in response to the proposed rule and responds to all those comments in the docket for this rulemaking. EPA responds to significant comments in the final rule. Paperwork Reduction Act, 44 U.S.C. sections 3501-3520 EPA states that the final rule imposes no new information or recordkeeping requirements. Statutory authorization for the rule Two sections of the Clean Air Act govern the establishment and revision of the NAAQS, section 108 (42 U.S.C. sect. 7408) and section 109 (42 U.S.C. sect. 7409). Executive Order No. 12,866 The final rule was reviewed by the Office of Management and Budget and found to be an –economically significant— regulatory action under the order. Executive Order No. 13,132 (Federalism) EPA concluded that the final rule will not have a substantial direct effect on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government.
