How does the Emissions Calculator calculate CAPs and HAPs?
The Air Services calculator is designed to automate the calculation of emissions using the throughput value, the uncontrolled emissions factor, the efficiency and the uncontrolled hours of operation. It is important to note that the emissions factor needs to be an uncontrolled factor and be reported in units consistent with the material and throughput information.If the emissions factor cannot be provided in units consistent with the material and throughput information, the user needs to select an emissions method of calculation and attach the calculations in a spreadsheet. For HAPs, the default calculation method is FIRE but the user can select other methods which may be pertinent to his operation. For CAPs, the user is expected to pick the best calculation method for each pollutant. In the pollutant’s list, the calculator identifies all the CAPs and only those HAPs with default emissions factors. The CAPs are listed first and the user must complete the information for all pollutants
