Approval of Air Plan Revisions; Arizona; Rescissions and Corrections

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Arizona State Implementation Plan (SIP) under the Clean Air Act. These revisions include rescissions of certain statutory provisions, administrative and prohibitory rules, and test methods. The EPA is also taking direct final action to correct certain errors in previous actions on prior revisions to the Arizona SIP and to make certain other corrections. The intended effect is to rescind unnecessary provisions from the applicable SIP and to correct certain errors in previous SIP actions.
