| 99-27878 | Rescinding Findings That the 1-Hour Ozone Standard No Longer Applies in Certain Areas | Proposed Rule | Today, EPA is proposing to rescind its prior findings that the 1-hour ozone national ambient air quality standard (NAAQS) and its accompanying designations and classifications no longer apply in certain areas. The EPA had previously taken final action regarding the applicability of the 1-hour standard for various areas on June 5, 1998, July 22, 1998, and June 9, 1999. A recent ruling of the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) has undermined the basis for EPA's previous determinations on applicability of the 1-hour ozone standard. In the ruling, the court remanded the 8- hour NAAQS for ozone and curtailed EPA's authority to enforce it. The effectiveness of the 8-hour standard served as the underlying basis for EPA's regulations governing these applicability determinations and thus for EPA's finding that the 1-hour standard no longer applied in areas that EPA determined were attaining the 1-hour standard. Since the court has ruled that EPA cannot fully implement the 8-hour standard, and it may be some time before EPA is able to take steps to secure the public health protection afforded by an 8-hour standard, EPA is today proposing to rescind the findings that the 1-hour standard no longer applies, and thereby reinstate the applicability of the 1-hour standard. Under this proposal, the designations and classifications that previously applied in such areas with respect to the 1-hour standard would be reinstated. Furthermore, in today's action, EPA is proposing to amend 40 CFR 50.9(b) to provide by rule that the 1-hour ozone standard will continue to apply to all areas notwithstanding promulgation of the 8-hour standard. | 1999-10-25 | 1999 | 10 | https://www.federalregister.gov/documents/1999/10/25/99-27878/rescinding-findings-that-the-1-hour-ozone-standard-no-longer-applies-in-certain-areas | https://www.govinfo.gov/content/pkg/FR-1999-10-25/pdf/99-27878.pdf | Environmental Protection Agency | 145 | Today, EPA is proposing to rescind its prior findings that the 1-hour ozone national ambient air quality standard (NAAQS) and its accompanying designations and classifications no longer apply in certain areas.
