The Emissions Inventory System (EIS) is the new information system for storing all current and historical emissions inventory data. It will be used to receive and store emissions data and generate emission inventories beginning with the 2008 National Emissions Inventory (NEI). Network partners will be able to use their Exchange Network Nodes to submit data to the EIS. The EIS will use the Consolidated Emission Reporting Schema (CERS) for reporting of data from the state, local and tribal agencies. Once complete, this data exchange will replace the current NEI data exchange, which will no longer be used after the 2007 NEI.
The Flow Configuration Document (FCD) for for the EIS exchange is currently under development. The EIS will use a new XML schema called the Consolidated Emission Reporting Schema (CERS), which is available below. In March 2008, several offices within EPA, encouraged by stakeholders involved in
programs associated with air emissions reporting, initiated the development of the Consolidated
Emissions Reporting Schema (CERS). The objective of this effort was to develop a common air
emissions reporting schema that could be used for sharing and reporting air pollution emissions
data in the U.S. In particular, the schema is designed to support the reporting of criteria air
pollutants and air toxic emissions, as well as greenhouse gases. The resulting benefits include
greater efficiencies for States and industry reporters submitting to multiple programs, clearer and
consistent requirements across these programs, and the capability to utilize agency infrastructure,
including the Exchange Network, to share these data among network participants.
