HOTSPOTS ANALYSIS REPORTING PROGRAM

HARP Maps

Background

The Hotspots Analysis and Reporting Program (HARP) is a tool that assists with the programmatic requirements of the Air Toxics "Hot Spots" Program. HARP is a single integrated software package that can be used by the air pollution control and air quality management districts (districts), facility operators, and other parties to promote statewide consistency, efficiency, and cost-effective development of facility and emission inventories and health risk assessments. HARP can also be used for other types of health risk assessments used in other programs (e.g., facility permitting).  To download a copy of the HARP software, please go to the HARP download page.

HARP is an integrated software package that will:
  • Create and manage facility emission inventory databases. These databases can be easily transmitted to the local air districts and the ARB;
  • Calculate facility prioritization scores;
  • Perform atmospheric dispersion analyses using screening or representative meteorology on one or multiple facilities using the U.S. Environmental Protection Agency's atmospheric modeling software ISCST3 and BPIP;
  • Calculate cancer and noncancer (acute and chronic) health impacts using the new risk assessment guidelines developed by the Office of Environmental Health Hazard Assessment (OEHHA);
  • Use point estimates or data distributions of exposure to calculate inhalation and multipathway risks;
  • Perform stochastic analyses;
  • Calculate potential health effects for individual receptors;
  • Calculate population exposure;
  • Calculate cumulative impacts for one or multiple facilities and one or multiple pollutants;
  • Calculate potential health effects using a ground level concentration;
  • Present the results as tabular reports and onscreen maps with contours. The results can be printed, added to word processing documents, or off-ramped to a Geographic Information Systems (GIS) program.
