Emission Inventory District Resources - Inventory Software and Tools
This page last reviewed March 13, 2013
The ARB and the US EPA have developed a number of software tools to estimate, prepare, and submit emission inventory data.
HARP - Hot Spots Analysis and Reporting Program
This is a comprehensive toxics prioritization and risk assessment software package for use by districts in implementing the AB2588 "Hot Spots" program. It is based upon guidelines developed by OEHHA.
CEIDARS-Lite - Emission Inventory Database
This software is the database portion of the HARP Risk Assessment software. It uses almost the same database format as ARB's CEIDARS 2.5 and districts can use this database to store and submit their data to the ARB. It uses Microsoft Access as its data engine and advanced users can access inventory data directly from Microsoft Access using the CEIDARS 2.5 Data Dictionary as a guide.
