Section 139.51. Purpose

The intent of this subchapter is to require the periodic monitoring of air contaminants emitted from certain sources which have or are likely to have a substantial impact on the maintenance of ambient air quality standards or may cause air pollution. The identification of sources subject to this subchapter, or the establishment of a specific frequency of source emission monitoring in this subchapter, will not be construed to limit the Department’s authority under section 4 of the act (35 P. S. § 4004) or § 127.12 (relating to content of applications) to establish monitoring requirements for other sources, or additional monitoring requirements for sources subject to this subchapter.

The provisions of this § 139.51 adopted August 12, 1977, effective August 29, 1977, 7 Pa.B. 2251; amended March 17, 1989, effective March 18, 1989, 19 Pa.B. 1169. Immediately preceding text appears at serial page (128492).
