Point source emissions inventory data is stored in our State of Texas Air Reporting System (STARS). Only those sites whose emission rates exceed the reporting applicability levels found in( 30 Texas Administrative Code 101.10Exit the TCEQ ) are tracked. Currently, there are approximately 2,000 industrial sites updating emissions annually.

Site level summary emissions data is available in MS Excel format for inventory years 2014 through 2020: Download the file 2014-2020statesum.xlsx (1533K). The emissions are represented in tons per year during routine operations.

To obtain site specific emissions inventory reports such as: 1) Path List 2) Contaminant Summary Report 3) Emissions Inventory Questionnaire 4) Actual History Report and 5) Air Emission Inventory, follow the instructions listed under the application/pdfEmissions Inventory ReportsExit the TCEQ.
