Emission Inventory for Ozone and Fine Particulates (PM2.5)

An emission inventory is an estimate of air pollutant emissions in a given area. Emission inventories are fundamental building blocks used to develop air quality control strategies on a local, regional and national level. Emission inventories are also used to estimate the progress of an air quality program.

The BAQP is responsible for compiling an annual inventory of emissions from all major point sources in New Jersey. An emissions inventory for five sectors (point, area, onroad, mobile, nonroad mobile, and biogenics) is done on a periodic basis as required by the USEPA. The periodic inventory includes sources of biogenic (natural) and anthropogenic (human-made) emissions.

The 2002 inventory for ozone and PM2.5 includes the precursors to ozone and PM2.5, which consist of the following pollutants: VOC, NOx, carbon monoxide, particulate matter less than 10 micrometers in diameter (PM10), PM2.5, sulfur dioxide (SO2), and ammonia (NH3). For more information on the Department's most current SIP Inventory (2002) for ozone and PM2.5, please refer to Appendix D of the "8 Hour Carbon Monoxide National Ambient Air Quality Standard, 1 Hour Ozone National Ambient Air Quality Standard, Fine Particulate Matter National Ambient Air Quality Standard and the 2002 Periodic Emission Inventory," dated May 2006.

The pie charts show the estimated contribution from each inventory sector, for each of the inventory pollutants in the 2002 Emissions Inventory.

2002 VOC - 470,689 Tons Per Year	2002 VOC - 1,350 Tons Per Day
2002 NOx - 352,968 Tons Per Year	2002 NOx - 1,110 Tons Per Day
2002 Carbon Monoxide 2,206,719 Tons Per Year	2002 Carbon Monoxide 5,554 Tons Per Day
2002 PM10 - 41,538 Tons Per Year	2002 PM2.5 - 30,381 Tons Per Year
2002 Ammonia - 25,514 Tons Per Year	2002 SO2 - 94,672 Tons Per Year
