Dear Mr. Garvin: 

Enclosed for your approval is a revision to Pennsylvania's State Implementation Plan (SIP) 

concerning amendments to 25 Pa. Code Chapters 121 and 139 (relating to general provisions; 

and sampling and testing) clarifying certain requirements regarding the "Measurement and 

Reporting of Condensable Particulate Matter Emissions." The final rulemaking was effective 

upon publication in the Pennsylvania Bulletin on April 12, 2014 (44 Pa.B. 2236). 

The final rulemaking amends 25 Pa. Code § 139.12 (relating to emissions of particulate matter) . 

to require the measurement and reporting of filterable and condensable particulate matter when 

testing to determine emissions of particulate matter (PM) from stationary sources, including 

coarse particles with diameters equal to or less than 10 micrometers and larger than 

2.5 micrometers and fine particles with diameters equal to or less than 2.5 micrometers. The 

final rulemaking also amends 25 Pa. Code § 139.53 (relating to filing monitoring reports) to 

require submittal of periodic emissions monitoring test reports to the Department of 

Environmental Protection's (DEP) Regional Air Program Manager where the source is located; a 

copy of the report must also be submitted to the DEP Chief of the Source Testing and 

Monitoring Division. The 'final rulemaking also adds definitions for the terms "condensable 

particulate matter" and "filterable particulate matter" to 25 Pa. Code § 121.1 (relating to 

definitions). .
