6.3 Nonpoint PM augmentation

QA procedures eliminated much of the functionality needs from the PM Augmentation Tool that was used in NEIs prior to 2020. For the nonpoint data category, the results from EIS PM Augmentation serve to merely supplement PM components (PM-CON, PM25-FIL, PM25-PRI, PM10-FIL, and PM10-PRI) where expected and where SLTs did not submit. PM Augmentation zeroes out any computed PM component less than zero that could result from arithmetic operation of SLT and PM augmented species; for example, computed PM-CON from SLT-submitted PM10-PRI minus PM10-FIL that exceeds SLT-submitted PM25-PRI (which would result in computed PM25-FIL being less than zero).
