Section 139.12. Emissions of particulate matter

(a) Tests for determining emissions of filterable particulate matter from stationary sources to demonstrate compliance with the particulate matter emission standards in § § 123.11—123.13 (relating to combustion units; incinerators; and processes) shall conform with the following:

(1) Test methods for particulate matter emissions shall include dry filters and provide for at least a 95% collection efficiency of particulate matter.

(2) Isokinetic sampling procedures shall be used in sampling for particulate matter emissions and the weight determined gravimetrically after the removal of uncombined water.

(3) Test methods and procedures shall be equivalent to those specified in § 139.4(5) (relating to references). The equipment shall be inert where appropriate and similar to that specified in § 139.4(1).

(4) The minimum sampling time shall be 1 hour or as specified in an applicable standard or by the Department and the minimum sample volume shall be 50 cubic feet or as specified in an applicable standard or by the Department, corrected to standard conditions (dry basis).

(5) Results shall be calculated based upon sample train component weights specified in § 139.4(5). Results shall be reported as pounds of particulate matter per hour and in accordance with the units specified in § § 123.11—123.13.

(b) The owner or operator of a stationary source subject to emission limitations for PM-10 and PM_2.5 or to applicability determinations required under Chapter 127, Subchapters D and E (relating to prevention of significant deterioration of air quality; and new source review) shall demonstrate compliance for filterable and condensable PM-10 and PM_2.5 emissions.

(c) Compliance with a particulate matter, PM-10 or PM_2.5 emission limitation issued by the Department prior to January 1, 2011, will not be based on condensable particulate matter unless required under the terms and conditions of a plan approval, operating permit or the State Implementation Plan codified in 40 CFR 52.2020 (relating to identification of plan).

(d) A compliance demonstration required under subsection (b) or (c) must include the measurement and reporting of filterable and condensable particulate matter. Test methods and procedures used to determine compliance must be equivalent to those specified in § 139.4(5). An owner or operator must obtain the Department’s prior written approval for the use of methods and procedures that are not prescribed in the Source Testing Manual.

(e) The Source Test Manual referenced in § 139.4(5) is subject to revision in accordance with the procedures in § 139.5 (relating to revisions to the source testing manual and continuous source monitoring manual).

The provisions of this § 139.12 adopted March 3, 1972, effective March 20, 1972, 2 Pa.B. 383; amended June 22, 1979, effective July 1, 1979, 9 Pa.B. 2150; corrected June 29, 1979, effective July 1, 1979, 9 Pa.B. 2150; amended November 25, 1994, effective November 26, 1994, 24 Pa.B. 5899; amended December 26, 1997, effective December 27, 1997, 27 Pa.B. 6804; amended May 1, 1998, effective March 7, 1998, 28 Pa.B. 2035; amended April 11, 2014, effective April 12, 2014, 44 Pa.B. 2236.
