    March 1999: Proposed Updates to the Phoenix 15 Percent Rate of Progress Plan

    March 19, 1999: EPA proposed minor changes to its 1998 15 percent rate of progress federal implementation plan (1998 FIP) for the metropolitan Phoenix ozone nonattainment area. The changes delete or add to the control strategy measures that have already been adopted in the Phoenix area. EPA proposed no new emission control regulations. This proposal did not alter EPA's basic conclusion that the Phoenix metropolitan area would meet the 15 percent Rate of Progress requirement as soon as practicable.

    October 1997: Phoenix Fails to Attain the 1-hour Standard for Ground-Level Ozone

    October 27, 1997: EPA determined that the Phoenix metropolitan area failed to meet the health-based 1-hour air quality standard for ground-level ozone (smog) by its Clean Air Act deadline of November 15, 1996. As a result of this finding, the EPA reclassified the area's ozone air quality from "moderate" to "serious." This classification triggered new planning and control requirements to continue progress toward attaining the ozone standard by the end of 1999.
