harp -- The Hot Spots Analysis and Reporting Program software suite has been updated Posted: 23 Feb 2017 16:31:41
The California Air Resources Board (ARB) has released updates for the Hot Spots Analysis and Reporting Program (HARP) software suite. On February 21, 2017, OEHHA adopted new acute, 8-hour, and chronic inhalation Reference Exposure Level (REL) values for carbonyl sulfide. The REL values and summary can be found at: http://oehha.ca.gov/air/crnr/notice-adoption-reference-exposure-levels-carbonyl-sulfide. • A new version of the HARP2 Air Dispersion Modeling and Risk Tool (ADMRT) (dated 17052) has been packaged with the latest health database. To download this software or to see a complete list of changes, please visit the HARP website at http://www.arb.ca.gov/toxics/harp/admrt.htm. • The HARP2 Risk Assessment Standalone Tool (RAST) has been repackaged with the latest health database. To download this software or to see a complete list of changes, please visit the HARP website at http://www.arb.ca.gov/toxics/harp/rast.htm. Alternatively, the health database can be updated using the “Help->Check for Updates” feature in the main menu of the program. • The health database for HARP2 Emission Inventory Module (EIM) has been updated to reflect the new RELs. To update the health database for HARP2 EIM, open the EIM, then click menu “Help->Check for Updates” and follow the on-screen instructions. • The Consolidated Table of Office of Environmental Health Hazard Assessment (OEHHA)/ARB Approved Risk Assessment Health Values has also been updated and can be downloaded at: http://www.arb.ca.gov/toxics/healthval/healthval.htm. Note: Please uninstall the older software version before installing any of the above software. Although uninstalling HARP software would only remove HARP program files, we recommend backing up your data before uninstalling the software to prevent accidental data loss. There are currently technical issues with the installer overwriting existing files. After installing the software, please uses the Help -> Check for Updates feature to make sure you are using the latest health information. California is in a drought emergency.
