Tegan Blades Treadaway, Administrator


The Air Permits Division (APD) within the Office of Environmental Services is responsible for preparing the following types of air permits:

The APD also handles a number of other actions, including requests for administrative amendments, authorizations to construct, changes of tank service, Emission Reduction Credit (ERC) certificates, exemptions to test, small source exemptions, and variances.  See the Louisiana Guidance for Air Permitting Actions link below for a more thorough description of these documents.

Also within the APD is the Emissions Reporting and Inventory Center (ERIC).  This area includes management of emissions information that is reported directly to the DEQ by industry. The ERIC system consolidates reporting for both the criteria and toxic air pollutants. Here you can view historical EI and TEDI reports, and get information about the EPA's National Air Toxics Assessment (NATA) Report. You can also access Toxics Release Inventory (TRI) resources that include EPA's website and archived Louisiana TRI Reports.

See the APD's Work Plans.
