B. Particulate Matter. The purpose of this Chapter is to maintain concentrations of particulate matter in the ambient air at levels which will not cause damage or injury to plant or animal life. In addition to health considerations, attainment of the standards will result in economic and aesthetic benefits such as increased visibility and reduced soiling and corrosion.

The standards of ambient air quality listed in Tables 1 and 1a define the limits of air contamination by particulates and gases, above which limits the ambient air is hereby declared to be unacceptable and requires air pollution control measures. Until additional pertinent information becomes available through surveillance and research with respect to the effects of the air contaminants listed in Tables 1 and 1a, the air quality limits listed in Tables 1 and 1a shall apply in Louisiana. The limits stated include normal background levels of particulates and gases.
