Point Source Emissions Inventory

Summary data and other information related to the TCEQ's Point Source Emissions Inventory.

The Point Source Emissions Inventory is an annual survey of chemical plants, refineries, electric utility plants and other industrial sites that meet the reporting criteria in the TCEQ emissions inventory rule (30 TAC §101.10 Exit the TCEQ).

This Web page provides point source emissions inventory data along with tools and information of use to companies completing their annual Emissions Inventory questionnaires.

Point Source Emissions Inventory Trends

The table that follows gives point source emissions data for the last four completed calendar years, including information on routine industrial emissions in tons per year (tpy) for the sources that met the reporting requirements of Rule 101.10 and submitted an emissions inventory for that year. It lists the following pollutants: volatile organic compounds (VOC), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), and particulate matter less than ten microns in diameter (PM10). Note that Inventory Trends are rounded to the nearest thousand.

Detailed Data from the Point Source Emissions Inventory

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 101.10 Exit 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: Update! Download 2011statesum.xlsx (289K) or the 2012statesum.xlsx (291K). Both file were updated January 2014. 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 Emissions Inventory Reports.

Customize data extracts are available and may require a fee. To request customize data extracts, complete the Emissions Data Request Form (PDF) and fax it to 512/239-1515.
