ERIC and DEQ's Emission Inventory Operations



ERIC Account Transitions

As a part of the process to increase the performance of the ERIC system, the Department made the decision to move ERIC into the business area of our website.  This has simplified the ERIC account and login processes and aligned ERIC in the same area as our E-Payment, On-line Permitting, and online submissions applications.  For more information, follow this link to 2013 Reporting Guidance.

About the Emissions Inventory Program

The Emissions Inventory Unit of the Air Permits 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 nearly 1200 point sources going back to 1984, 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.
