  1. Particulate Matter Monitoring in the Eastern Sierra Region A Brief History Presented by Great Basin Unified Air Pollution Control District

  2. Monitoring Synopsis • Great Basin Unified Air Pollution Control District formed in 1974 • Monitoring in Eastern Sierra began in 1978 using high-volume samplers collecting total suspended particulate matter (TSP) • District began monitoring PM10 in 1985 • Federal EPA PM10 standard promulgated July 1, 1987 • Owens Valley Planning Area designated Nonattainment for PM10 August 7, 1987

  3. Monitoring Rationale • Regulation-driven • Determination of Attainment Status • Determining Compliance

  4. Monitoring Timeline

  5. High-Volume TSP Monitoring1978-1989

  6. High-Volume PM10 MonitoringAndersen SSI 1985 - 2006Wedding 1988 - 1997 PM10 Intercomparison 1988 - 1989

  7. Continuous PM10 MonitoringTapered Element Oscillating Microbalance1990 - Present

  8. Portable PM10 Monitoring

  9. Portable PM10 Monitor Power System

  10. Mini-Vol PM10 Monitor

  11. Flood Irrigation Project PM10 Monitor Constructed by the District for the North FIP PM10 Monitoring Program 1993 - 1994

  12. Sequential Partisol PM10 Monitor1999 - Present

  13. Keeler PM10 Monitors2000 - Present

  14. Low-Power PM10 MonitorsSolar-powered BGI Monitors - Mono Lake2000 - 2008

  15. Solar-Powered TEOM Monitor2007 - Present

  16. Solar-Powered TEOM Monitor2007 - Present

  17. Special Studies • PM10 Monitoring Methods Comparison at Owens Lake 1993-1999 • E-BAM - FDMS/TEOM Comparison 2005 • Met One eSampler - TEOM Comparison 2006`

  18. Monitoring Methods Comparison: TEOM vs. Wedding SSI

  19. Monitoring Methods Comparison: TEOM vs. Graseby SSI

  20. Monitoring Methods Comparison: TEOM vs. Dichtomous Sampler

  21. Monitoring Methods Comparison: TEOM vs. Partisol Samplers

  22. Special Studies:E-BAM vs. FDMS/TEOM - 2005

  23. Special Studies:E-BAM vs. FDMS/TEOM - 2005

  24. Special Studies:eSampler vs. TEOM

  25. Considerations and Recommendations • EPA Reference or Equivalent Method Monitors are required to Determine Compliance/Attainment • Dust ID Model Requires Hourly Data • EPA-approved Monitors providing Hourly PM10 Concentrations are the TEOM and the BAM • Light-scattering and Beta Attenuation monitors have had numerous precision, accuracy, calibration, and maintenance issues • District Network should utilize TEOM monitors
