CHAPTER 121. GENERAL PROVISIONS § 121.1. Definitions.

The definitions in section 3 of the act (35 P. S. § 4003) apply to this article. In addition, the following words and terms, when used in this article, have the following meanings, unless the context clearly indicates otherwise:

***** Computer diskette jacket manufacturing adhesive —Anadhesive intended by the manufacturer to glue the foldover flaps to the body of a vinyl computer diskette jacket.

Condensable particulate matter—Material that is vapor phase at stack conditions but which condenses or reacts, or both, upon cooling and dilution in the ambient air to form solid or liquid particulate matter immediately after discharge from the stack. All condensable particulate matter, if present from a source, is typically in the PM 2.5 size fraction and therefore all of it is a component of both PM 2.5 and PM-10.

Confined space —A space that is the following: (i) Large enough and so configured that an employee can enter and perform assigned work.

(ii) Has limited or restricted means for entry or exit— for example, fuel tanks, fuel vessels and other spaces that have limited means of entry.

(iii) Not suitable for continuous employee occupancy.

***** Fiberglass—

(i) For purposes of §§ 129.301—129.310 (relating to control of NO

x emissions from glass melting furnaces), material consisting of fine filaments of glass that are combined into yarn and woven or spun into fabrics, or that are used as reinforcement in other materials or in masses as thermal or as acoustical insulating product.

(ii) For purposes of §§ 129.77 and 130.702 (relating to control of emissions from the use or application of adhesives, sealants, primers and solvents; and emission standards), a material consisting of extremely fine glass fibers.

Filterable particulate matter —Particles directly emitted by a source as a solid or liquid at the stack, or similar release conditions, and captured on the filter of a stack test train.

Final repair coat —Liquids applied to correct imperfections or damage to the topcoat.

CHAPTER 139. SAMPLING AND TESTING Subchapter A. SAMPLING AND TESTING METHODS AND PROCEDURES
STATIONARY SOURCES § 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 shallinclude 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 weightdetermined 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 oras 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). Subchapter B. MONITORING DUTIES OF CERTAIN SOURCES

GENERAL § 139.53. Filing monitoring reports.

(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:
