A. General. It is hereby declared to be the public policy of the state to achieve and maintain such levels of air quality as will protect human health and safety, and to the greatest degree practicable prevent injury to plant and animal life and property, foster the comfort and convenience of the people, promote the economic and social development of this state and facilitate the enjoyment of the natural attractions of the state.
B. Particulate Matter (Suspended Particulates). The purpose of this Subsection is to maintain concentrations of suspended particulate matter (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.

D. Carbon Monoxide. It is the purpose of this Subsection to establish ambient air quality standards for the state for carbon monoxide and to enumerate methods for measuring carbon monoxide concentration in the ambient air.
E. Reserved.
F. Atmospheric Oxidants. It is the purpose of this Subsection to establish ambient air quality standards for the state for atmospheric oxidants and to enumerate methods for measuring oxidant concentrations in the ambient air.
G. Nitrogen Oxides. It is the purpose of this Subsection to establish ambient air quality standards for the state for nitrogen oxides and to enumerate methods for measuring concentrations of nitrogen oxides in the ambient air.
H. Lead. The purpose of this Subsection is to maintain concentrations of lead in the ambient air at levels which will protect human health and safety, and to the greatest degree practicable, prevent injury or damage to plant and animal life and property.

Section 705. Standards
Approved by EPA 03/08/89 (54 FR 09795) at 52.970(c)(49) effective 05/08/89.
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.
AUTHORITY NOTE: Promulgated in accordance with R.S. 30:1084.
HISTORICAL NOTE: Promulgated by the Department of Environmental Quality, Office of Air Quality and Nuclear Energy, Air Quality Division in LR 13:741 (December 1987).

Section 707. Degradation of Ambient Air Having Higher Quality than Set Forth in these Sections Restricted
Approved by EPA 03/08/89 (54 FR 09795) at 52.970(c)(49) effective 05/08/89.
As of the effective date of these regulations all processes which currently result in higher ambient air quality than shown in Tables 1 and 1a shall be maintained at the higher process quality level or better unless it can be affirmatively demonstrated to the administrative authority that a change in quality is justifiable.
AUTHORITY NOTE: Promulgated in accordance with R.S. 30:1084.

A. PM10, PM2.5, sulfur dioxide, carbon monoxide,
atmospheric oxidants, nitrogen oxides, and lead shall be
measured by the methods listed in LAC 33:III.711.C, Table
2 or by such other equivalent methods approved by the
department. The publications or their replacements listed in
LAC 33:III.711.C, Table 2 are incorporated as part of these
regulations by reference.
B. The sampling and analytical procedures employed and their numbers, duration and location of samples to be taken to measure ambient levels of air contaminants shall be consistent with obtaining accurate results which are statistically significant and representative of the conditions being evaluated.
