The EPA Inspector General issued an audit report on February 21, 2013, analyzing oil and gas production emissions data contained in the 2008 National Emissions Inventory. The IG drew several conclusions from its review, including that the data is limited and incomplete for several key air pollutants, and that there are data gaps for some oil and gas activities, such as “nonpoint” sources (i.e., wells). The IG concludes that EPA should develop better emissions estimates for oil and gas production operations; given that EPA has acknowledged the need for better data, it is likely that additional data needs (and requirements) will be identified in the future.
