Emission Inventory

An emission inventory is a tabulation of all of the sources of air pollutant emissions and the emissions from these sources 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 track accountability and assess air quality program effectiveness.

BAQP is responsible for compiling an annual inventory of actual emissions from all major point sources regulated in New Jersey.  An inventory for all sectors (point, area, onroad, mobile, nonroad mobile, and biogenics) is required by USEPA every three years.  This information allows the DEP to determine the total amount of air emissions being released into the atmosphere by regulated sources and is used to develop air pollution reduction strategies for specific sources contributing to air pollution problems in New Jersey.

This 2002 inventory is a compilation of the emissions from sources of biogenic (natural) and anthropogenic (human-made) VOC, NOx, carbon monoxide, particulate matter less than 10 micrometers in diameter (PM10), PM2.5, sulfur dioxide (SO2) and ammonia (NH3) in the outdoor air.  The sources are divided into five sectors and each making up one component of the inventory: point sources, area (nonpoint) sources, onroad sources, nonroad sources, and biogenic sources.

The pie charts show the major air contaminants estimated within the 2002 Emissions Inventory.  As can be seen from these charts, VOC emissions are occurring from all sectors of the inventory with no sector having a much more predominant role than the others. On-Road mobile sources predominate the NOx and carbon monoxide emissions and point sources predominate the sulfur dioxide emissions. Area sources predominate the releases of ammonia and particulate matter (PM2.5 and PM10).

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
