HARP Update

The California Air Resources Board (CARB) has released an updated California Emission Inventory Development and Reporting System (CEIDARS) utility database for the Hot Spots Analysis and Reporting Program (HARP) Emission Inventory Module (EIM).  The information in the CEIDARS utility database is used to assist with data entry and quality assurance.  The following tables have been updated:

  • CATEGORY - Category Information  
  • EIC - Emission Inventory Codes
  • FRACTION - Organic and Particulate Matter Fractions Information
  • NAICS - North American Industrial Code System
  • POLLUTANT - Pollutant Information
  • SCC - Sources Classification Codes

Due to server security changes, the automatic download option in HARP is currently unavailable.  Staff is currently working on addressing this issue.

To get the new CEIDARS utility database, you must download and install the new database using the link below.  Installation instructions are also included.
