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 ).

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

Pollutant (tpy)	2008	2009	2010	2011
Annual Inventory Trends
VOC	115,000	107,000	102,000	102,000
NOx	373,000	334,000	327,000	322,000
SO2	602,000	550,000	552,000	512,000
CO	396,000	337,000	305,000	310,000
PM10	28,000	54,000	52,000	53,000
Total	1,650,000	1,382,000	1,338,000	1,299,000

Detailed Data from the Point Source Emissions Inventory

The TCEQ collects information about air pollutants emitted from industrial point sources in Texas that 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 ) are tracked. Currently, there are approximately 2,000 industrial sites updating emissions annually.

Site level summary emissions data is available in MS Excel format: Download 2011statesum.xlsx (281K). File updated January 2013.

The emissions are represented in tons per year during routine operations. To request detailed site specific data or reports, complete the Emissions Data Request Form (PDF) and fax it to 512/239-1515. Point source emissions data may also be obtained by contacting the TCEQ IR Data Clearinghouse.
