Point Source Emission Inventory

This inventory for the state of Texas includes emissions of NOx, SO2, CO, total and selected speciated VOCs, PM2.5, and PM10 from 1858 fixed-location pollution sources statewide, identified by their Texas Commission on Environmental Quality (TCEQ) account number. The data are based on TCEQ's 2004 annual totals, with updates of NOx and SO2 emitted by electric power generation facilities to August 2005 levels. Facility information (company, site name, county, latitude/longitude, and Standard Industrial Classification code) is also included.

The data set structure is very similar to that used in the TexAQS 2000 study. The 1999 emissions of NOx, SO2, CO, and total VOC and the 1999 facility coordinates from that study are included for reference purposes.

These data are meant to be an interim tool for mission planning and initial analysis of observations until a complete, official inventory is available. Look for updates to this data set during and after the field study. The data should be considered only preliminary estimates of current emissions.
