## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Arizona State Implementation Plan (SIP). These revisions include two State statutes and certain State rules that govern stationary sources under the jurisdiction of the Arizona Department of Environmental Quality and that establish definitions and other general provisions; ambient air quality standards and area designations; and emissions limitations and other requirements for certain types of stationary sources. Generally, approval of these revisions updates and replaces previously approved provisions in the Arizona SIP, but the EPA is also approving a few rules that are new to the Arizona SIP and a few rescissions that remove certain other rules from the Arizona SIP without replacement. The EPA is approving these revisions because they meet all applicable requirements of the Clean Air Act.
