The Pollutant Code

The EIS Pollutant Code reporting tables list all the current Pollutant Codes available for use in the Emissions Inventory System. The list includes all the hazardous air pollutants (HAPs) identified by the EPA as well as the Criteria Pollutants (CAPs) regulated by the Clean Air Act. Greenhouse Gas Pollutants are also identified and HAPs are further broken down into HAP types to indicate if they are HAP-VOCs, Acid-Gases, or HAP-Metals. When emissions are submitted to the EIS, they must have a valid pollutant code or they will be rejected.

The Pollutant Codes table includes the following information:

  • Pollutant Code
  • Description of Pollutant Code
  • Pollutant Types
  • HAP Type
  • Pollutant Category Name
  • Last Inventory Year - If the pollutant is retired, this field will be populated with the last inventory year the pollutant was active
  • Map To
  • Standard Unit of Measure
  • Default Facility Maximum Annual Emission
  • Pollutant Synonym
