______________

Acceptable Source Impact Level (ASIL) means a concentration of a toxic air contaminant in the outdoor atmosphere in any area that does not have restricted or controlled public access that is used to evaluate the air quality impacts of a single source. There are 3 types of acceptable source impact levels:

			Averaging Time
Risk-Based	Type A	carcinogens	annual arithmetic mean
Threshold-Based	Type B	non-carcinogens	24-hour arithmetic mean
Special	Type C	carcinogens	24-hour arithmetic mean
