Ozone monitoring requirements were 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 believes that certain changes are needed in the ozone minimum monitoring requirements to account for the newly 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). In this rulemaking, EPA will propose: (1) modest changes to minimum monitoring requirements in urban areas, (2) minimal monitoring requirements in rural areas, and (3) incremental adjustments to the length of the ozone monitoring season where indicated by statistical analysis. These proposed actions have been developed in response to comments that were received from some States, national monitoring associations, and environmental groups during the Ozone NAAQS proposal that was published on July 11, 2007 (72 FR 37818). No changes will be proposed in ozone measurement methodology, quality assurance requirements, or probe siting requirements. Therefore, the implementation of any proposed changes should be routine for affected monitoring agencies.

EPA is proposing to revise the network design requirements for ozone (O3) to support changes to the primary and secondary National Ambient Air Quality Standards (NAAQS) for O3 that were finalized in a recent final rulemaking, 73 FR 16436, March 27, 2008. For the purpose of this ICR, we have estimated the maximum potential burden for the options being considered in the proposed rule. The ICR burden estimates are associated with the current ozone monitoring portion of the approved ICR, 2060-0084 - "Ambient Air Quality Surveillance."
