  2. Overview: • Who we are? • Existing air monitoring activities -Fixed ozone monitors -Neighborhood screening -Nuisance odor complaint summa canister sampling • Future air monitoring program elements • Where do we go from here?

  3. Who we are • Local enforcement agency for Harris County since 1953. Merged with HCPHES (Harris County Health Department) in 1998 • Enforce TCEQ air, water, solid waste rules and the Harris County Storm Water regulations • 24 hour complaint response • Civil and criminal enforcement

  4. Harris County’s Public Health Ozone Monitoring System When and Why: • Started 2002, 12 sites added to the regional Network • Data and notification more proximate to more citizens, health professionals, coaches and hospitals • Fill gaps in system in populated areas for modeling and animation purposes

  5. Harris County’s Public Health Monitoring Network (con’t) How: • Locate ozone monitors in existing public buildings • SEP funding $250,000 for equipment • Installation, administration, calibration, and maintenance funded by Harris County • Data to existing TCEQ database for public access and email notifications (http://ozone.hcoem.org)

  7. Neighborhood Screening • Pilot program initiated January 2005 • Use Hapsite - portable GC/MS • Survey neighborhoods closest to petrochemical facilities and industrial sources • Survey sites also include nuisance odor complaint database input • Emergency Response neighborhood screening, i.e. fires, explosions

  8. Nuisance Odor Complaint Summa Canister Sampling Program • Summa canister sample collected as part of some nuisance odor investigations • Odor must be present at the time investigation is conducted • Inherent transient nature of nuisance odors is a complicating factor • Links enforcement with health impacts

  9. Sample results (ppbv)

  10. Future Air Monitoring Program Elements • Fourier Transform Infrared System( FTIR) • Fixed station located in Pasadena. Near real-time reporting of HRVOCs and secondary target list of compounds including some air toxics. • Data available to TCEQ network and available to the community with the TCEQ website • Summa Canister Pre-concentrator System • Enhanced air toxics and HRVOC analysis capability • Co -located Met. towers • Currently one, two to be added

  11. Where do we go from here? • Goal–reduce industrial odor complaints • Institutionalize neighborhood screening and odor driven summa canister pilot programs • Improve data analysis of both in-house and TCEQ data • Better coordination with City of Houston BAQC and TCEQ , Region 12 and Austin
