ADEQ's Air Quality Division welcomes comments on the proposed Arizona ozone infrastructure State Implementation Plan (SIP) revision under Clean Air Act (CAA) section 110(a)(1) and (2). Arizona proposes to submit a revision to the Arizona SIP to satisfy CAA infrastructure requirements for the implementation of the 2015 ozone National Ambient Air Quality Standard. The proposed plan will be submitted to the Environmental Protection Agency to demonstrate that the State of Arizona has the necessary resources to implement, maintain, and enforce ozone air quality standards.
