Draft Emission Inventory 2011

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, typically every 3 years, as required by the USEPA. The periodic inventory includes sources of biogenic (natural) and anthropogenic (human-made) emissions.
The New Jersey 2011 inventory includes the precursors to ozone and PM2.5, which consist of the following pollutants: volatile organic compounds (VOC), oxides of nitrogen (NOx), carbon monoxide (CO), fine particulate matter (PM2.5), course particulate matter (PM10), sulfur dioxide (SO2), and ammonia (NH3). For more information on the Department's most current SIP Inventory (2011) for ozone and PM2.5, please refer to Appendix II of the Proposed "State Implementation Plan (SIP) for the Attainment and Maintenance of the 75 ppb 8-Hour Ozone National Ambient Air Quality Standard Reasonably Available Control Technology (RACT) Determination, 2011 Periodic Emission Inventory, and 8-Hour Carbon Monoxide National Ambient Air Quality Standard Maintenance and Monitoring Plan," dated July 2014.

The following pie charts show the estimated contribution from each inventory sector, for each of the inventory pollutants in the 2011 Emission Inventory.


2011 Volatile Organic Compound Emissions
552 Tons Per Summer Day

2011 Volatile Organic Compound Emissions
Including Biogenic Sources
896 Tons Per Summer Day

2011 Oxides of Nitrogen Emissions
581 Tons Per Summer Day

2011 Carbon Monoxide Emissions
2,700 Tons Per Summer Day

2011 Fine Particulate Matter Emissions
23,637 Tons Per Year

2011 Sulfur Dioxide Emissions
23,637 Tons Per Year

2011 Ammonia Emissions
10,544 Tons Per Year

 
 
 

The following charts show the emission trends from 2002 to 2011, from human-made sources, for each of the inventory pollutants in the 2011 Emission Inventory.
