Southeast Texas Photochemical Modeling Technical Committee

A former advisory group that assisted the TCEQ with technical and scientific issues related to air quality modeling and analysis in the Houston-Galveston-Brazoria and Beaumont-Port Arthur areas.

The Southeast Texas Photochemical Modeling Technical Committee (SET PMTC) meetings were held from 2004 to 2019. The Houston-Galveston-Brazoria Air Quality Technical Information Meeting presents air quality modeling, data analysis, research, and agency planning efforts.
