Hot mix asphalt plants
Hot mix asphalt (HMA) plants can release substances from Part 1, 4 and 5. (Part 2 substances – PAHs – are also released from asphalt plants but these releases need not be reported as they are considered to be intentional.)The calculator focuses on releases to air and uses default emission factors. It can be adapted to use site-specific emission factors.
