Refinery Emissions Inventory Guidelines

View the Refinery Emissions Inventory Guidelines, a resource for the use of petroleum refineries and Air District staff in calculating emissions inventories.

The Air District’s Refinery Emissions Inventory Guidelines provide standardized methods and instructions for calculating emissions from petroleum refineries. These guidelines are based on emission estimates from the U.S. EPA’s Emission Estimation Protocol for Petroleum Refineries.
