LAC 33:III.901. Purpose

A. It is the purpose of these emission standards to set forth levels of air quality for the protection of public health and of public welfare from any known or anticipated adverse effects of air contaminants. These standards set forth a mechanism of achieving cleaner air and are not a permit for unnecessary degradation of air quality. Therefore, quality of emissions as of the effective date of these standards shall be maintained at the higher degree of quality unless it can be affirmatively demonstrated to the administrative authority that a change in quality is justifiable and will not be contrary to the purpose of these regulations.
