Data Exchange Description
The Emissions Inventory System (EIS) is EPA’s information system for storing all current and historical emissions inventory data. It is used to receive and store emissions data and generate emission inventories beginning with the 2008 National Emissions Inventory (NEI). Partners use the EIS Exchange to submit Facility Inventory, Point, Nonpoint, Onroad, and Nonroad data categories to the EIS Production or QA environments.
The EIS uses the Consolidated Emission Reporting Schema.
The Flow Implementation Guide provides a high-level overview of the EIS submission process and data flow. Beginning with the 2020 National Emissions Inventory, EIS only accept the “CERS_v2” data flow. Please note the change in the data flow name (previously “EIS_v1_0”). A description of the changes for the 2020 National Emissions Inventory can be found here. These changes are planned to be implemented in production EIS in June of 2021.
