Air Emissions Reporting Requirements (AERR)
On this page:
The AERR requires state and local agencies to collect and submit emissions data to the EPA. In 2015, the EPA has finalized improvements to these reporting requirements by:
- Lowering the current threshold for reporting lead emissions sources as "point sources";
- Eliminating the requirement for state and local agencies to report emissions from wildfires and prescribed fires;
- Requiring agencies to report the inputs needed to model emissions from mobile sources;
- Removing the requirements for agencies to report daily and seasonal emissions, and;
- Clarifying, removing, or simplifying some current emissions reporting requirements.
The EPA promulgated the AERR in December 2008. The AERR consolidated and streamlined previous requirements of several older rules for states and local air pollution control agencies to submit emissions inventories for criteria polluntants to EPA's Emissions Inventory System (EIS). The EPA uses these submittals, along with other data sources (primarily for air toxics), to build the National Emissions Inventory (NEI). Many of the states voluntarily report air toxics along with the required criteria air pollutants, and these air toxics reports are also used in building the NEI.
