Subchapter B. MONITORING DUTIES OF CERTAIN SOURCES

§ 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.

 Persons responsible for the operation of sources subject to monitoring requirements established by order, by condition of plan approval or permit, or under this subchapter, shall:

   (1)  Conduct source testing or air sampling and perform analyses in accordance with the requirements of Subchapter A (relating to sampling and testing methods and procedures), or shall install, operate and maintain a device approved by the Department for installation in a flue for the purpose of continuous measurement of specific air contaminants.

   (2)  Perform visible emission observations in accordance with the methods for observing and recording visible emissions established pursuant to Chapter 123 (relating to standards for contaminants); provided, however, visible emissions discharged through a flue may also be monitored by use of a device approved by the Department for installation in a stack for the purpose of measuring opacity.

   The provisions of this §  139.52 adopted August 12, 1977, effective August 29, 1977, 7 Pa.B. 2251.

 (a)  Persons responsible for the operation of sources subject to monitoring requirements established by order, by condition of plan approval or permit or under this subchapter, shall submit periodic reports of the results of tests, samples or observations conducted, obtained or made in accordance with the methods or techniques referenced in §  139.52 (relating to monitoring methods and techniques). The reports shall be:

   (1)  Submitted on forms supplied or in a format specified by the Department.

   (2)  Sworn by the person exercising managerial responsibility over the operation of the source for which monitoring is required.

   (3)  Submitted on the schedule established by order, condition of plan approval or permit or this subchapter.

   (4)  Submitted to the Regional Air Pollution Control Engineer for the region of the Department in which the source is located.

 (b)  In addition to the information required by subsection (a) the Department may, by use of a standard form or by written notice, require information regarding test methods, test conditions, operating conditions of the source or other information which may be necessary to properly evaluate the results of emissions monitoring performed at a source.

   The provisions of this §  139.62 adopted August 4, 1978, effective August 5, 1978, 8 Pa.B. 2164; reserved December 26, 1997, effective December 27, 1997, 27 Pa.B. 6804. Immediately preceding text appears at serial pages (233623) to (233624).
