Point Source Emission Inventory


A revised point source emission inventory (EI) for the 8-county Houston-Galveston-Brazoria (HGB) area is now available. Texas counties included in the inventory are Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller. This revised inventory is based on the best available data from the Texas Commission on Environmental Quality (TCEQ) for the period of the 2006 Texas Air Quality Study (TexAQS), and it is therefore the recommended emission data set for analysis of 2006 TexAQS observations.

The interim point source emission inventory (EI) remains available. These data should be considered only preliminary estimates of current emissions, as these data were meant to be an interim tool for mission planning and initial analysis of observations until a complete, official inventory became available.
