This page contains links to all of the WAQS emissions data for oil and gas sources in the Intermountain West. The inventory data will be used for WAQS 2014 (base year) modeling.


The inventories are a mix of permitted (point) and survey-based (non-point) annual emissions. Descriptions of the files and file formats are provided below.
