HARP Update

The California Air Resources Board (CARB) has released updated health tables for the Hot Spots Analysis and Reporting Program (HARP) Air Dispersion Modeling and Risk Tool (ADMRT), Risk Assessment Standalone Tool (RAST) and Emission Inventory Module (EIM). 

These updates include: 

  • New cancer unit risk and inhalation slope factors for 1-bromopropane (106-94-5).
  • A new Bay Area AQMD health table.  Zinc chromate was inadvertently left out of the previous update.

To get the new health database, select the “Help > Check for Updates” feature in the main menu of each program.  This feature will automatically download and update the health databases.  Once downloaded, restart each program to use the new health databases.

Other Updates

Note: CARB staff are in the process of updating the CEIDARS pollutant table.  The HARP CEIDARS utility database will be updated once this work is completed.  Although the updated pollutant table is not available yet, pollutants with health values can be manually added in the ADMRT and RAST.
