Missouri State Implementation Plan Revision – Section 110 Infrastructure Requirements for the 2008 Ozone National Ambient Air Quality Standard
This plan was developed to fulfill the requirements of Section 110(a) of the Clean Air Act for the revised 2008 National Ambient Air Quality Standard (NAAQS) for ozone. Section 110(a)(1) requires states to submit a state implementation plan (SIP) revision such as this after the promulgation of a new or revised NAAQS to address the implementation, maintenance, and enforcement infrastructure elements of Section 110(a)(2) for that NAAQS. On January 15, 2013, the EPA published in the Federal Register findings of failure to submit for several states, including Missouri, that had not made any submission to address the applicable elements of Section 110 for the 2008 Ozone NAAQS (78 FR 2882). However, this finding did not apply to Section 110(a)(2)(D)(i)(I), the “interstate transport” provisions of the infrastructure SIP. This plan is administrative in nature and demonstrates Missouri’s ability and authority to implement all Section 110 elements for the 2008 Ozone NAAQS for which EPA has issued this finding of failure to submit via the referencing of specific corresponding applicable state statutes, regulations, programs or resources.
A public hearing is scheduled for this plan action on May 30, 2013. Comments about this plan action will be accepted through the close of business on June 6, 2013.

Proposed Revision to the Boundary Recommendation of Nonattainment and Unclassifiable Areas per the 2010 1-hour Sulfur Dioxide (SO2) National Ambient Air Quality Standard
The U.S. Environmental Protection Agency is moving forward with finalizing designations under the 2010 1-hour Sulfur Dioxide (SO2) NAAQS. Based on the 2010-2012 monitoring period, Missouri plans to submit a revised area boundary recommendation as an amendment to the original boundary recommendation and technical support document submitted to EPA on July 19, 2011. Based on the most recent certified 2010-2012 data from the three SO2 monitors operating in Greene County, the Springfield area is no longer in violation of the 1-hour SO2 NAAQS and will be recommended for designation as unclassifiable.
A public hearing on this plan action was held on March 28, 2013. Comments about this plan action were accepted through close of business April 4, 2013. No comments were received. The revised boundary recommendation is listed below.
