  1. National Monitoring Committee Report Bruce Louks WESTAR Fall Meeting Portland, OR September 28, 2010

  2. NAAQS Update • SO2 - final June 2, 2010 • Monitors do not have to be source-oriented. • Monitoring required by January 1, 2013. • NCore stations apply to network minimums. • 5-minute data reporting to AQS will be required for data collected 60-days past final rule publication date (June 22, 2010) • Modeling guidance expected late fall 2010. • EPA/NACAA workgroup will develop guidance.

  3. NAAQS Update • Pb – Final rule December 2010 • Network Plans due July 2011. • Monitoring commences January 1, 2012 for point sources ≥ 0.5 tpy. • Due to delay in final rule date, Ncore monitoring may be extended to January 1, 2012. • ≥ 0.5 tpy airports (~20-25) will be listed in final rule for “pilot” monitoring, commencing January 1, 2013. • EPA will fund use of contractors

  4. NAAQS Update • O3 – final rule approximately October 31, 2010 • 2007 – 2009 ozone data may change EPA’s monitoring season recommendations (not as compelling to lengthen season in most cases). • Wyoming will be year-round, Utah may be year-round. • EPA is considering a 2-year phase-in of ozone monitoring network ( ½ in 2012, ½ in 2013 ). • Data will be rounded in all steps. • EPA is evaluating circumstances in Wyoming relating to the secondary NAAQS (W126) and winter-time high ozone.

  5. NAAQS Update • NOx/SOx secondary NAAQS – proposal expected summer of 2011. • NAAQS will be based on ecosystems and acidification/fertilization potential to aquatic and terrestrial systems. • CMAQ modeling will be used to determine deposition velocities. • EPA expects little impact to monitoring organizations.

  6. NAAQS Update • CO – EPA is considering 8-hour/1-hour NAAQS. Final rule expected January 2011. • Likely to be near-roadway component. • Continued urban canyon for maintenance. • NO2 – final rule published January 22, 2010. • New monitors in place by January 1, 2013. • Network plans by July 1, 2012. • EPA and NACAA will partner on developing siting guidance. • EPA near-roadway pilot study planned ($1M STAG) – meeting with CASAC to finalize monitoring objectives.

  7. NAAQS Update • PM – Final rule expected end of fall, 2011. • Policy assessment recommends range of 11-13 µg/m3 for the annual and 35 µg/m3 for the 24-hour PM2.5 NAAQS. • Eliminates spatial averaging. • Annual NAAQS will be the “driver” for many airsheds. • Secondary PM2.5 NAAQS – light extinction in urban areas. • EPA leaning away from nephelometer/aethelometor monitoring. • Likely to use IMPROVE algorithm applied to hourly FEM PM2.5 continuous data. • Policy assessment recommends 98th percentile 24-hour PM10 standard of 65-85 µg/m3.

  8. Other Issues • Acrolein data – pending final approval • EPA proposes to move all AQS acrolein data to “unverified” category. • States then can move data to “verified” category if confident in validity of data. • NCore – EPA scheduled national call to discuss implementation issues (September 14, 2010). • NOy calibration and best practices. • Possible addition of Pb. • NACAA letter to ORD asking for greater resource commitment by EPA toward method development. • Driving issues: poor continuous PM2.5 performance in some locations, acrolein method issues discovered during School Air Toxics study, upcoming PM10-2.5 NCore monitoring requirements.

  9. Other Issues • NATTS network assessment workgroup formed. Preparing work assignment for contractor, which should be ready prior to upcoming air toxics data analysis workshop in Dallas (spring 2011). • Community Scale Air Toxics program funded in FY11. EPA will encourage communications with EJ communities and community programs. • PAMS re-invention is still moving forward. Multidisciplinary team of EPA/NACAA stakeholders will develop recommendations/plan by summer 2011. Will involve meeting(s) with CASAC AAMS.

  10. Funding • FY10 - $5.5M still on table. • ~$3M for monitoring. • ~2.5M for training and RPOs. • FY11 – additional $15M for monitoring. • Approved before elections? Likely continuing resolution. • FY12 – probably 5% reduction for EPA at agency level. • Impact on air not known. • 103-105 transition. • NACAA proposes 10% first year. • EPA waiting to see what happens. • Reallocation – no changes.
