17.1 Sector Descriptions and Overview
The road dust sector reflects emissions of particulate matter from vehicles driving over paved and unpaved roads. The SCCs that belong in this sector are provided in Table 17.1. Fugitive dust emissions from paved and unpaved road traffic were estimated for PM10-PRI, PM10-FIL, PM25-PRI, and PM25-FIL. Since there are no PM-CON emissions for this category, PM10-PRI emissions are equal to PM10-FIL emissions and PM25-PRI emissions are equal to PM25-FIL emissions.
