CenSARA Region Air Quality Overview
NASA AQAST MeetingJan. 15-17, 2014
Rice University, Houston
CenSARA Members
Organization Purpose:• Promote the exchange of air
quality information, knowledge, experience and data
• Support members in technical projects through contract management and representation on regional/national groups
• Increase staff productivity through management of training courses for member agency staff
Arkansas DEQIowa DNRKansas DHELouisiana DEQMissouri DNRNebraska DEQOklahoma DEQTexas CEQFederally-funded local programs are represented on the Board of Directors by one agency each from EPA Region 6 and Region 7

PM10 NAAQS – El Paso County (part), TX – moderate nonattainment
2010 SO2 NAAQS (Phase I)
1971 SO2 NAAQS – Muscatine County, IA (part) – maintenance area
1978 Lead NAAQS – Jefferson County (part), MO – nonattainment; Iron County (part), MO – maintenance
Douglas County (part), NE – maintenanceCollin County ([art), TX -maintenance
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?
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• Many of EPA’s area source emission factors are outdated.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.
