        <RULE_TITLE>Ambient Ozone Monitoring Regulations: Revisions to Network Design Requirements</RULE_TITLE>
        <ABSTRACT><![CDATA[Ozone monitoring requirements were last revised in October 2006 during a comprehensive revision of ambient monitoring requirements contained in 40 CFR parts 50, 53, and 58. These changes included revised minimum monitoring requirements for ozone monitors in urban areas as well as changes to the length of the required monitoring season. As stated in the Ozone National Ambient Air Quality Standards (NAAQS) final rule published on March 27, 2008 (73 FR 16436), EPA believed that certain changes were needed in the ozone minimum monitoring requirements to account for the revised levels of the NAAQS (primary and secondary NAAQS levels for ozone were revised from an eight-hour level of 0.08 ppm to an eight-hour level of 0.075 ppm). EPA proposed such monitoring network design changes on July 16, 2009 (74 FR 34525) which included: (1) changes to minimum monitoring requirements in urban areas, (2) new monitoring requirements in non-urban areas, and (3) revisions to the length of the ozone monitoring season where indicated by statistical analysis. 

In this rulemaking, EPA will finalize changes to ozone monitoring requirements based on public comments received from the 2009 proposal, technical analysis of updated ozone monitoring data covering the period of 2007-2009, and selected use of new data for 2010 that was referenced in a Notice of Data Availability published on November 10, 2010 (75 FR 69036).]]></ABSTRACT>
