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

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• Many of EPA’s area source emission factors are outdated.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.
