  1. National Monitoring Steering Committee Report Gordon Pierce WESTAR Fall Business Meeting Denver, CO November 6, 2013

  2. CSN Assessment • Need to make the CSN network sustainable • Currently 190 sites • Objectives of CSN: • Support PM2.5 implementation • Support trends analyses • Aid with health studies • Need to: • Leverage other resources (IMPROVE, PAMS, etc.) • Redistribute resources to higher priority sites • CSN assessment: • Target 30% reduction in budget • Assess network effectiveness and efficiency • Develop recommendations by end of 2013

  3. PAMS Re-engineering • EPA still looking at changing the PAMS network, probably associated with next ozone NAAQS • Now have consensus on a network design: • NCore sites in ozone non-attainment areas • State-directed enhanced ozone in non-attainment areas • Required analytes: • O3, NO, true NO2, NOy, hourly VOC, aldehydes, mixing height • Auto-GC evaluation will occur • Need to update date analysis tools

  4. PM2.5 Monitoring Implementation • Agencies need to list in annual network plans how they are using continuous PM2.5 data • FEM-like? • Need to request that not to be used for NAAQS comparisons (a template is now available) • PM2.5 Continuous Monitor Comparability Assessment Tool is available on web and has recently been updated • ORD is not working on PM methods at this time • PM2.5 methods still have issues: • Met-One BAM needs good grounding and is affected by humidity • Thermo 2025i has software issues • Thermo TEOM 1405 has a new valve available

  5. Near-Road NO2 • Rule finalized to add 1-year to the implementation timeline to sync with budget and available funds • Phase 1 now required by 1/1/2014 (instead of 1/1/2013) • Phase 2 now required by 1/1/2015 (instead of 1/1/2014) • Problem: Funding for Phase 1 has all been allocated, but sequestration has now affected available funds for Phase 2 • Plan is to look at 2014 budget to find funds for 19 Phase 2 sites • Will assess data after 1 or 2 years to see if need for Phase 3 sites (500,000 MSAs) to see if need by 1/1/2017 or revise rules to eliminate

  6. Monitoring Rules • EPA is starting to look at common-sense revisions to monitoring rules in 2014 • Clarify QA (40 CFR 58 Appendix A) • Reduce data certification requirements • Clarify monitoring network plan requirements • Revise NO2 network timeline • Are trying to avoid OMB review, so will stay away from hot-topics at this point • Send any comments/suggestions to Lew Weinstock

  7. SO2 Technical Assistance Documents • New TAD allows for use of actual emissions instead of potential-to-emit • In-house testing has showed that the model performs fairly well • Problems with TAD: • Data requirements rule missing which would specify the threshold of sources to look at • Doesn’t address short-term peaking units • No specifics on number of monitoring sites required • 5-minute exposures not addressed • Monitor shut-down not addressed for when sources have major emissions reductions or shut down • Monitoring vs modeling timeframes are different • Send comments to EPA

  8. Air Toxics • Carbonyl measurements are problematic • Formaldehyde is the #1 risk driver on NATA • Existing sampling and analysis methods have known issues • Metals proficiency test samples are only provided on quartz-fiber filters, but many agencies using teflon filters for samples • Many of the TO methods are out of date and should be revised • Possibly use some of the PAMS analysis funds to work on carbonyl and other methods

  9. Lab Competency Policy • Agencies required to have competency/certification documentation if receive over $200,000 • Not supposed to be an additional burden • Implementation being pushed back to 2014 • Labs do not have to be certified, but if they are, it can be used as documentation to satisfy the policy • QAPPs can be used as documentation to satisfy the policy • A list of acceptable documents is to be developed by EPA

  10. Community/Citizen Monitoring • Had some good discussions at the meeting • Will be discussed in Hot-Topics session later

  11. Next Monitoring Conference now set for August 2014 in Atlanta • Next MSC meeting December 4-5, 2013 in San Francisco Questions?
