Determination of Attainment by the Attainment Date But for International Emissions for the 2015 Ozone National Ambient Air Quality Standards; Phoenix-Mesa Nonattainment Area, Arizona

Published Date: 4/6/2026

Rule

Summary

The EPA says the Phoenix-Mesa area in Arizona met the 2015 ozone air quality goals on time, if you don’t count pollution coming from other countries. This means local efforts worked well, but international emissions still affect the air. The correction updates a key date to April 22, 2026, so everyone’s on the same page about deadlines.
