ADVISORY - Comprehensive Emission Inventory (CEI) Requirements Beginning Emission Year 2025 

This advisory provides information regarding more rigorous CEI requirements: The California Air Resources Board (CARB) is requiring more information than in previous emission years. The increased requirements are due to CARB utilizing the CEI data to satisfy the requirements of multiple CARB programs including:

• The AB 2588 Air Toxics "Hot Spots" Emission Inventory Criteria and Guidelines Regulation (Hot Spots/ECIG)
• Regulation for Reporting Criteria Air Pollutants and Toxic Air Contaminants (CTR)
• Air Emissions Reporting Requirements (AERR, implemented by USEPA) 

In efforts to meet these requirements, the District will be requiring facilities to submit reports which include more detailed information than has been approved/accepted in the past.
