About the Emissions Inventory Program

The Emissions Inventory Unit of the Air Quality Assessment Division is responsible for developing comprehensive criteria and toxic pollutant emissions inventories for the State of Louisiana. The emissions data are used for a variety of planning, regulatory and reporting purposes. The staff works closely with the regulated community, trade groups, and other state and federal agencies to develop and maintain high quality and current emissions data

Regulated point sources of criteria air pollutants must submit an inventory of annual criteria pollutant emissions pursuant to the requirements of LAC 33:III.919.  Detailed annual emissions data are maintained on point sources going back to 1991, with the number of point sources changing each year.

In 2007, historical emissions data was migrated into a new web-based reporting system called ERIC - Emissions Reporting & Inventory Center.  ERIC's functionality includes a query tool for use by the public.
