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 gives 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).

Annual Inventory Trends
Pollutant (tpy)	2003	2004	2005	2006
VOC	150,000	146,000	145,000	132,000
NOx	530,000	493,000	456,000	433,000
SO2	822,000	764,000	758,000	734,000
CO	533,000	489,000	487,000	451,000
PM10	65,000	67,000	66,000	64,000
Total	2,100,000	1,959,000	1,912,000	1,814,000

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.

Emissions data are available for the 2,000 sites in PDF. The reports are organized by account number, county, SIC code, or company name. The industrial emissions are represented in tons per year.

2006 Point Source Emissions (Routine) Summary Data as of July 2008
Report Type	Filename	File Size
Sorted by account number	sum_acc.pdf	425K
Sorted by county	sum_cnty.pdf	427K
Sorted by SIC code	sum_sic.pdf	450K
Sorted by company name	sum_co.pdf	445K

If you need summary information for analysis in your database or spreadsheet program, a delimited text file (fields separated by pipes/delimited by quotes) is available. This text file provides the same information as the reports in the tables above and the fields remain in the same order: Download sum.txt (332K). The industrial emissions are represented in tons per year. The file is also available as an Excel spreadsheet: Download 2006statesum.xls (585K).

For point source emissions data prior to calendar year 2005 contact the TCEQ IR Data Clearinghouse.
