March 2015: Direct Final Rule on Arizona's Infrastructure SIP Submittals Addressing Stage II Vapor Recovery

March 30, 2015 - the EPA is approving the State of Arizona's Stage II vapor recovery SIP revision in a direct final action without prior proposal because we believe this SIP revision is not controversial. A detailed rationale for the approval is set forth in the direct final rule. If we receive adverse comments, however, we will publish a timely withdrawal of the direct final rule and address the comments in a subsequent final rule based on the proposed rule.

May 2013: Approval and Promulgation of Implementation Plans; Arizona; Motor Vehicle Inspection and Maintenance Programs

May 22, 2013 - EPA approved three revisions to the Arizona State Implementation Plan. Two of these revisions relate to an amendment to Arizona's vehicle emissions inspection program that exempts motorcycles in the Phoenix metropolitan area from emissions testing requirements. The third revision expands the geographic area in which various air quality control measures, including the vehicle emissions inspection program but also including other control measures, apply in the Phoenix metropolitan area. This rule is effective on June 21, 2013.
