2002 Periodic Emissions Inventory

Carbon Monoxide


This inventory includes emissions of carbon monoxide (CO) for both Maricopa County and the CO non-attainment area. Annual totals as well as typical CO season-day (winter) emissions are provided for all source categories.

Ozone Precursors


An Ozone Precursor inventory includes:
  • Carbon monoxide (CO)
  • Emission estimates for volatile organic compounds (VOC)
  • Nitrogen oxides (NOx)
Emissions are calculated for both Maricopa County and the eight-hour ozone non-attainment area. Annual totals as well as season-day emissions are provided for all source categories.

Particulate Matter 10 (PM10)


A Particulate Matter inventory includes emissions estimates for:
  • Ammonia (NH3)
  • Coarse particulate matte; less than 10 microns in diameter (PM10)
  • Fine particulate matter; less than 2.5 microns (PM2.5)
  • Nitrogen oxides (NOx)
  • Sulfur oxides (SOx)
Emissions are calculated for both Maricopa County and the PM10 non-attainment area. Annual totals as well as typical daily emissions are provided for all source categories.

Computational Errors


Computational errors, discovered in March 2006, in the 2002 Periodic Emissions Inventory (PEI) for PM10 have resulted in the revised electronic version of the main document and affected chapters (now denoted with “revised March 2006”). These corrections are described more fully in the 2-page errata sheet also provided.
