HARP Emission Inventory Module v2.0 is now available.

The Emission Inventory Module can create and manage facility emission inventory databases. This data can be transmitted to the local air districts and the ARB. The Emission Inventory Module can also calculate facility prioritization scores.

Note: ARB is currently updating the HARP software. This version is the first of three modules that will eventually replace the existing HARP version 1 series. ARB anticipates on having the Air Dispersion and Risk Assessment Modules available when the OEHHA “Hot Spots” Guidance Manual is adopted. The new version of HARP will include AERMOD and the updates to the OEHHA “Hot Spots” Risk Assessment Guidelines. HARP version 1 series will continue to be available until all the HARP2 modules are available.

Note: You must uninstall any test versions before installing the program. Do not attempt to use data created during the testing period.

November 2013
A new HARP Health Database is now available.

In the process of updating the Air Toxics Hot Spots Risk Assessment Guidelines, OEHHA conducted a review of all chemical summaries. In their review, target organs were clarified for some pollutants, the applicability of health values were changed for several pollutants, and a new policy was made to treat development and reproductive system as one target organ. In addition, OEHHA has adopted new Reference Exposure Levels (RELs) for caprolactum. These updates are reflected in OEHHA’s Online REL and Cancer Potency Table. With these updates, the HARP Health Database has also been updated to reflect recent changes to OEHHA’s REL and Cancer Potency Table. For questions or more information on the changes, please contact Daryn Dodge of OEHHA at (916) 445-9375.

April 2013
ARB is currently updating the HARP software. This latest version is different from the previous versions of HARP. The new version of HARP has been separated into three individual programs (Emission Inventory Module, Air Dispersion Module, and the Risk Assessment Module) which will allow users to access any of the modules independently from each other. As in the previous version, the information can still be shared between each program. For consistency, the three programs are still referred to as the Emission Inventory Module, Air Dispersion Module, and the Risk Assessment Module. The new version of HARP will also include AERMOD and the updates to the OEHHA “Hot Spots” Risk Assessment Guidelines. ARB anticipates on having the Air Dispersion and Risk Assessment Modules available within six months to a year after the final part of the OEHHA “Hot Spots” Risk Assessment Guidelines is adopted.

At this time, the HARP 2 Emission Inventory Module is being released for a 30-day public review/testing period. During this testing period, please submit any comments or issues discovered to harp@arb.ca.gov. The deadline to submit comments is May 6, 2013. If you would like to test the new HARP 2 Emission Inventory Module, you may download the installation package and draft user manual at http://www.arb.ca.gov/toxics/harp/downloads.htm.

February 2011
A new HARP Health Database is now available.  This database contains updated health values for polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs).  The new health values have been revised to reflect the Office of Environmental Health Hazard Assessment‘s adoption of the World Health Organization’s 2005 Toxicity Equivalency Factors for PCDDs, PCDFs, and dioxin-like PCBs .

The new HARP Health Database can be downloaded.  To use it with HARP, you must replace your current health database located in the HARP main directory (typically C:\HARP) with the one you just downloaded.

The new health database is also available for the HARP On-Ramp.  To use this health database, you must replace the current database typically located at “C:\Program Files\CARB\HARP On-Ramp\Tables” with this one.  Please note that it is not necessary to update HARP On-Ramp’s Health Database as the new health values for PCDDs, PCDFs, and dioxin-like PCBs are not used by the HARP On-Ramp.  However, if you decide to update the database, it would be only for display purposes (i.e., showing the current health values).

 February 2009
The HARP Health Database has been updated.  Under directions from OEHHA, the oral chronic Reference Exposure Level (REL) for arsine was removed.  In addition, acute RELs with longer averaging periods (e.g., 4-hr, 6-hr, and 7-hr) will now use the 1-hr averaging period.  This includes:  
  • Arsenic & inorganic arsenic compounds
  • Benzene
  • Carbon disulfide
  • Carbon tetrachloride
  • Chloroform
  • Ethylene glycol monoethyl ether
  • Ethylene glycol monoethyl ether acetate
  • Ethylene glycol monomethyl ether
You may download the February 2009 version of the health database.  In order to use the new health database, you must replace the health database (health.mdb) under the HARP program directory (typically c:\HARP) with this file.

For more information on the changes to the HARP Health Database, please download the zip file.  Note that changes made in January are also included in this file.

 June 2008
A file was inadvertently left out of the HARP full setup file (HARP Version 1.4).  This file is used for the new Keyhole Markup Language feature which exports the risk contours from the HARP Risk Module to Google Earth.  If you have downloaded and installed the full setup file prior to 6/25/2008, you can get the missing file by downloading and installing the patch (harppatch062008.exe).

(Added June 25, 2008)



A clarification has been made to the HARP Health Database.  The May 2008 version of the database contains an oral cancer potency value for ethylbenzene.  HARP was not using this value to calculate multipathway risk.  The Office of Environmental Health Hazard Assessment has determined that ethylbenzene is not a multipathway pollutant for the Air Toxics “Hot Spots” Program Therefore, to avoid confusion, the oral cancer potency value has been removed from the June 2008 version of the HARP Health Database (health.mdb).

Please download the June 2008 version of the Health.mdb and save it to your HARP program directory (usually C:\HARP).  The new Health.mdb will overwrite the existing version of the health database (May 22, 2008).
