Toxic Air Pollutants Non-Carcinogenic Increments

01. Toxic Air Pollutant Non-carcinogenic Increments. Those ambient air quality increments based on occupational exposure limits for airborne toxic chemicals expressed in terms of a screening emission level or an acceptable ambient concentration for a non-carcinogenic toxic air pollutant. (7-1-25) 02. Non-carcinogens Table. The screening emissions levels (EL) and acceptable ambient concentrations (AAC) for non-carcinogens are as provided in the following table. The AAC in this section are twenty-four (24) hour averages.
