Ambient air quality standards

1. Particulates and gases. The standards of ambient air quality listed in table 1 and table 2 define the limits of air contamination by particulates and gases. Any air contaminant which exceeds these limits is hereby declared to be unacceptable and requires air pollution control measures. The stated limits include normal background levels of particulates and gases. 2. Radioactive substances. The ambient air shall not contain any radioactive substances exceeding the concentrations specified in article 33.1-10. 3. Other air contaminants. The ambient air shall not contain air contaminants in concentrations that would be injurious to human health or well being or unreasonably interfere with the enjoyment of property or that would injure plant or animal life. The department may establish, on a case-by-case basis, specific limits of concentration for these contaminants.
