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

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

3. 3 NAAQS Update  Pb – Final rule December 2010 o Network Plans due July 2011. o Monitoring commences January 1, 2012 for point sources ≥ 0.5 tpy. o Due to delay in final rule date, Ncore monitoring may be extended to January 1, 2012. o ≥ 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 EPA will fund use of contractors

4. 4 NAAQS Update  O 3 – final rule approximately October 31, 2010 o 2007 – 2009 ozone data may change EPA’s monitoring season recommendations (not as compelling to lengthen season in most cases). o Wyoming will be year-round, Utah may be year-round. o EPA is considering a 2-year phase-in of ozone monitoring network ( ½ in 2012, ½ in 2013 ). o Data will be rounded in all steps. o EPA is evaluating circumstances in Wyoming relating to the secondary NAAQS (W126) and winter-time high ozone.

5. 5 NAAQS Update  NO x /SO x secondary NAAQS – proposal expected summer of 2011. o NAAQS will be based on ecosystems and acidification/fertilization potential to aquatic and terrestrial systems. o CMAQ modeling will be used to determine deposition velocities. o EPA expects little impact to monitoring organizations.

6. 6 NAAQS Update  CO – EPA is considering 8-hour/1-hour NAAQS. Final rule expected January 2011. o Likely to be near-roadway component. o Continued urban canyon for maintenance.  NO 2 – final rule published January 22, 2010. o New monitors in place by January 1, 2013. o Network plans by July 1, 2012. o EPA and NACAA will partner on developing siting guidance. o EPA near-roadway pilot study planned ($1M STAG) – meeting with CASAC to finalize monitoring objectives.

7. 7 NAAQS Update  PM – Final rule expected end of fall, 2011. o Policy assessment recommends range of 11-13 µg/m 3 for the annual and 35 µg/m 3 for the 24-hour PM 2.5 NAAQS. Eliminates spatial averaging. Eliminates spatial averaging. Annual NAAQS will be the “driver” for many airsheds. Annual NAAQS will be the “driver” for many airsheds. o Secondary PM 2.5 NAAQS – light extinction in urban areas. EPA leaning away from nephelometer/aethelometor monitoring. EPA leaning away from nephelometer/aethelometor monitoring. Likely to use IMPROVE algorithm applied to hourly FEM PM 2.5 continuous data. Likely to use IMPROVE algorithm applied to hourly FEM PM 2.5 continuous data. o Policy assessment recommends 98 th percentile 24-hour PM 10 standard of 65-85 µg/m 3.

8. 8 Other Issues  Acrolein data – pending final approval o EPA proposes to move all AQS acrolein data to “unverified” category. o 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). o NO y calibration and best practices. o Possible addition of Pb.  NACAA letter to ORD asking for greater resource commitment by EPA toward method development. o Driving issues: poor continuous PM 2.5 performance in some locations, acrolein method issues discovered during School Air Toxics study, upcoming PM 10-2.5 NCore monitoring requirements.

9. 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. 10 Funding  FY10 - $5.5M still on table. o ~$3M for monitoring. o ~2.5M for training and RPOs.  FY11 – additional $15M for monitoring. o Approved before elections? Likely continuing resolution.  FY12 – probably 5% reduction for EPA at agency level. o Impact on air not known.  103-105 transition. o NACAA proposes 10% first year. o EPA waiting to see what happens.  Reallocation – no changes.
