12. SRPMIC Air Monitoring  Major air pollutants in the Community – Ozone (O 3 ) and Particulate Matters (PM 10 and PM 2.5 )  Monitors daily for PM 10, PM 2.5 and O 3,  Meteorological data collected daily and applied  Monitoring stations operated at the High School, Senior Center, Red Mountain, and Lehi  Submits data to National Emissions Inventory (NEI) and Air Quality System (AQS)

14. Trends

15. SRPMIC Regulatory Activities  Seeking from US EPA Treatment as a State (TAS) or Eligibility Determination status  Developing a Tribal Implementation Plan (TIP)  Drafting Community specific air quality ordinances to serve the Community better  Assists US EPA Region IX with enforcement of CAA in the Community  Enhance compliance and enforcement

16. Ordinance Development  Draft ordinances currently being developed by the Air Quality Program - Mining, Dust Control, Construction, and Open Burning  Several air quality rules (ordinances) will be combined and presented to the Council for consideration  Future plans – improve compliance and enforcement capabilities

17. Coordination with Neighbors  Gila River Indian Community  Fort McDowell Yavapai Nation  Ak-Chin Indian Community  Maricopa County  Arizona Department of Environmental Quality  Arizona Department of Transportation  US Environmental Protection Agency

18. Successful Collaborations  Joint Air Toxics Assessment Project (JATAP) – Partners include SRPMIC, GRIC, FMYN, NAU-ITEP, ITCA, AZ Dept. of Environmental Quality, Maricopa County, Pinal County, US EPA R9 and OAQPS
