Revisions to the Air Emissions Reporting Requirements: Revisions to Lead (Pb) Reporting Threshold and Clarifications to Technical Reporting Details

This action finalizes changes to the Environmental Protection Agency's (EPA) emissions inventory reporting requirements. This action lowers the threshold for reporting lead (Pb) emissions sources as point sources, eliminates the requirement for reporting emissions from wildfires and prescribed fires, and replaces a requirement for reporting mobile source emissions with a requirement for reporting the input parameters that can be used to run the EPA models that generate emissions estimates. This action also reduces the reporting burden on state, local, and tribal agencies by removing the requirements to report daily and seasonal emissions in their submissions under this rule, while clarifying the requirement to report these emissions under pollutant-specific regulations. Lastly, this action modifies some emissions reporting requirements which we believe are not necessary for inclusion in the Air Emissions Reporting Requirements (AERR) rule or are not clearly aligned with current inventory terminology and practices.
