a. Emission Rate. The rate at which contaminants are emitted to the air from point sources

(grams/second) and area sources (grams/second-square meter)

b. Dispersion Modeling. The process of using an air dispersion model and an emission rate to

calculate the concentration of contaminants in the air at a receptor point.

Emission Rate Action Level. The regulation or regulatory guideline emission rate for point

source emissions.

d. Receptor Point Action Level. The airborne concentration of a contaminant at the receptor,

which is considered (by regulation, regulatory guideline, or risk assessment practice)

unacceptable for public exposure.

Perimeter Air Monitoring Action Level. The airborne concentration of a contaminant to be

monitored at the site perimeter that has been demonstrated through dispersion modeling to be in

compliance with the receptor point action level.
