§ 131.4. Application of ambient air quality standards.

 The values specified in § §  131.2 and 131.3 (relating to National Ambient Air Quality Standards; and ambient air quality standards) shall be considered as representing minimum quality, but not necessarily desirable quality. Nothing contained in this chapter shall be construed to preclude the Department from enforcing or applying any provision of this article in areas where the ambient air quality is, or will be, at concentrations less than those specified in § §  131.2 and 131.3.
