EPA has replaced the PM-10 Calculator program with new software that

will estimate Filterable PM2.5 emissions. The new software, PM Calc is

applicable to point sources only and requires the user to input

uncontrolled emissions (either total filterable particulate or filterable

PM10) for each source, the source category classification (SCC) and the

control device, if any. The program will then calculate controlled

emissions for filterable PM2.5 and filterable PM10 for each point source.
