8. 1978 Lead NAAQS – Jefferson County (part), MO – nonattainment; Iron County (part), MO – maintenance Douglas County (part), NE – maintenance Collin County ([art), TX -maintenance

9. Thoughts to ponder As NAAQS become tighter, how can continued “clean air” in the central U.S. be assured? – Relevant, accurate and up-to-date data for use by EPA and states becomes ever more important. – Finding best uses of handheld/personal monitors and data collected is important. Accurate and informative public messaging is also important, as is coordination of messaging amongst agencies. – It’s unknown at this time what near-road monitoring results will mean. Technical “building blocks” can help with transport, NAAQS, and Regional Haze SIPs, but how? – Regional haze Phase II SIPs are due to EPA by July 31, 2018; NAAQS SIP due dates vary; transport SIPs due ?? – As sources of interest decrease in size, technical analysis needs increase. – How can a dynamic industry like oil and gas be accurately accounted for in current and future emission inventories and modeling?

10. Challenges Most CenSARA states have a minimum number of employees with limited time to work on “non- routine” activities. Many of EPA’s area source emission factors are outdated. There’s never enough time between regulatory requirement effective dates and deadlines to develop programs. – If you haven’t yet, please read a SIP to help understand what states have to do to meet requirements.
