Environmental Protection Agency (EPA).


Notice of public meeting.


The purpose of this document is to announce that EPA has scheduled a public meeting to solicit comments on various options to implement the 8-hour ozone national ambient air quality standard (NAAQS). The options contain EPA's preliminary views and are intended to initiate a dialogue with the public on approaches for implementing the 8-hour ozone NAAQS. The EPA is interested in hearing the views from interested stakeholders on the options that we've developed and their ideas on how to best implement the 8-hour ozone NAAQS consistent with the Supreme Court's decision in Whitman v. American Trucking Association. An overarching issue that EPA would like public input on is how EPA should address the Supreme Court's holding that subpart 2 of part D of title I of the Clean Air Act (CAA) applies for purposes of classifying areas under a revised ozone NAAQS.


The one-day meeting will be held from 9:00 a.m. to 5:00 p.m. (MST) on Wednesday, April 3, 2002, in Tempe, Arizona.


The meeting will be held at: Fiesta Inn Resort, 2100 S. Priest Drive, Tempe, Arizona 85282-1192.

On July 18, 1997, EPA revised the ozone NAAQS (62 FR 38856). At that time, EPA indicated it would implement the 8-hour ozone NAAQS under the less detailed requirements of subpart 1 of part D of title I of the CAA rather than more detailed requirements of subpart 2 requirements. Various industry groups and States challenged EPA's final rule promulgating the 8-hour ozone NAAQS in the U.S. Court of Appeals for the District of Columbia Circuit.[1] In May 1999, the Appeals Court remanded the ozone standard to EPA on the basis that EPA's interpretation of its authority under the standard-setting provisions of the CAA resulted in an unconstitutional delegation of authority. American Trucking Assns., Inc. v. EPA, 175 F.3d 1027, aff'd, 195 F.3d 4 (D.C. Cir. 1999). In addition, the Court held that EPA improperly interpreted the statute to provide for implementation of the 8-hour standard under subpart 1, but also determined that EPA could not implement a revised ozone standard under subpart 2. The EPA sought review of these two issues by the U.S. Supreme Court. In February 2001, the Supreme Court upheld the constitutionality of the air quality standard setting. Whitman v. American Trucking Assoc., 121 S. Ct. 903. In addition, the Supreme Court held that EPA has authority to implement a revised ozone standard but that EPA could not ignore subpart 2 when implementing the 8-hour standard. Specifically, the Court noted EPA could not ignore the provisions of subpart 2 that “eliminate[s] regulatory discretion” allowed by subpart 1. After determining that EPA could not ignore the provisions of subpart 2, the Court went on to identify several portions of the classification scheme that are “ill-fitted” to the revised standard, but left it to EPA to develop a reasonable approach for implementation. Any implementation approach that EPA develops must address the requirements of the CAA, as interpreted by the Supreme Court.

The EPA has initiated a process to obtain stakeholder feedback on options the Agency is developing for implementation of the 8-hour ozone NAAQS. The EPA plans to issue a final rule on the implementation strategy prior to designating areas for the 8-hour ozone NAAQS. The implementation rule will provide specific requirements for State and local air pollution control agencies and tribes to prepare implementation plans to attain and maintain the 8-hour NAAQS. States with areas that are not attaining the 8-hour ozone NAAQS will have to develop—as part of its State implementation plan (SIP)—emission limits and other requirements to attain the NAAQS within the time frames set forth in the CAA.[2] Tribal lands that are not attaining the 8-hour ozone standard may be affected, and could voluntarily submit a tribal implementation plan (TIP), but would not be required to submit a TIP. However, in cases where a TIP is not submitted, EPA would have the responsibility for planning in those areas.

The EPA is holding this meeting in order to obtain stakeholder feedback regarding the options that EPA has developed as well as to listen to any new or different ideas that stakeholders may be interested in presenting. The following topics will be covered at the meeting: (1) Classifications and attainment dates; (2) designations and transport; (3) attainment demonstration issues and transportation planning; and (4) other general SIP issues. New Source Review (NSR) programs that accompany nonattainment designations will not be the subject of this meeting since the EPA is currently considering whether and how to change the NSR program regulations in other contexts. The EPA has placed a variety of materials regarding implementation options, and which will be the focus of the meeting, on the website:​ttn/​rto/​ozonetech/​o3imp8hr/​o3imp8hr.htm. Additional material will be placed on the website as they are developed.Start Printed Page 11925Anyone interested in attending the meeting should check the website for new material on a regular basis prior to the meetings.

1. On July 18, 1997, EPA also promulgated a revised particulate matter (PM) standard (62 FR 38652). Litigation on the PM standard paralleled the litigation on the ozone standard and the court issued one opinion addressing both challenges.

2. The CAA requires EPA to set ambient air quality standards and requires States to submit SIPs to implement those standards.
