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—An

adhesive 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 PM2.5

size fraction and therefore all of it is a component of both

PM2.5 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 NOx 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.

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 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 PM2.5 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 PM2.5 emissions.

(c) Compliance with a particulate matter, PM-10 or

PM2.5 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:
