The District has published Guidelines for Preparing Air Toxics Emission Inventory Plans and Reports, which describe how to prepare an Air Toxics Emission Inventory Plan and Report for the AB 2588 Air Toxics “Hot Spots” Program.  The completed Modeling Protocol Tables for ATEIP must be submitted with the Air Toxics Emission Inventory Plan.

The District’s Approved Emission Factors for Toxic Air Contaminants and associated spreadsheet with emission factors, SBCAPCD-Approved TAC Emission Factors.xlsx, were updated.  Updates include emission factors for Hot Mix Asphalt Plants, Aggregate Materials and Haul Roads.  A complete list of changes can be found in the history of updates to approved emission factors for toxic air contaminants.  More information can be found on the District’s Toxic Air Contaminant Emission Factors webpage.
