Update on Condensable Particulate Measurement
Update on Condensable Particulate Measurement
Tuesday, December 9, 1:00 pm – 3:00 pm ET
Since 2011, the Condensable Particulate Matter (CPM) fraction of PM2.5 must be evaluated in permits and air planning. EPA Method 202 is now in its fourth iteration, but lack of replicability, even during different runs in the same test, continues to be a problem. Precursors, secondary formation and test artifacts add additional complexity. As ambient levels are lowered, the accuracy of mass-based approaches decreases significantly as you approach the (unknown for Method 202) detection level.
Kevin Crosby will review the evolution of condensable particulate test methods and guidance as they address known issues. Zach Emerson will summarize the state of current research on CPM Methods and the precursor bias associated with NH3, SO2 and moisture and will discuss bias adjustment approaches. Rich Trzupek will outline the impact of lower-level measurements in interpreting test results and present new research on precursor bias, followed by a speaker panel and Q&A session. Permittees and permit writers need to understand the strengths and weaknesses of CPM test methods.

Presenters:
Kevin Crosby, Vice President, Technical, Montrose Air Quality Services
Kevin is Vice President, Technical for Montrose Air Quality Services. He has been testing stack emissions his entire career, since 1976. He still learns something every day as there is always more to learn about processes and their emissions, and how best to measure those emissions. Kevin has special expertise in low-concentration measurements of PM, gases and Toxics, and has pioneered the development and use of methods such as EPA 202 and OTM-37. He has a background in ambient air quality monitoring and modeling, fluid dynamics and thermodynamics from attaining a BS in Meteorology from San Jose State University.
Zach Emerson, PhD, Director, Air Quality, NCASI
NCASI serves as the environmental research arm of the forest products industry. The NCASI Air Quality research program focuses on emissions from manufacturing operations, ambient impacts and air permitting. NCASI has worked with industry stakeholders and regulators to develop technically sound and achievable regulations for the forest product sector. Dr. Zach Emerson joined NCASI in 2007 as a research engineer and now manages the pulp and paper air program. His work has involved research on wastewater fugitive emissions, air modeling, and emissions measurement methods. His expertise includes air emissions estimates, empirical and numerical modeling, and troubleshooting. He routinely provides technical support to members for SARA reporting, MACT compliance, and air permitting. He is also a NCASI Member coordinator with responsibility for ~35 pulp mills.
Rich Trzupek, Vice President, Technical Operations, Alliance Technology Group
Rich Trzupek has been involved in source testing for forty years. He holds a bachelor’s degree in chemistry from Loyola University of Chicago. Mr. Trzupek is a recognized expert in both source sampling techniques and analytical methods, having worked both in the lab and on the stack throughout his career. He has published books and written numerous articles focused on environmental topics. Mr. Trzupek has been recognized as an expert witness regarding source sampling, analytical, environmental regulation and air pollution control issues. He has also testified before the United States House of Representatives on two occasions. Mr. Trzupek serves as Vice President of Technical Operations for the Alliance Technology Group.
Moderator: Harry Klodowski, Principal, Klodowski Law LLC
Harry Klodowski has practiced environmental law in Pittsburgh since 1979. While a student at SUNY Buffalo 1972-1979,(BA,BA,MA,JD) he watched the local Love Canal story develop into CERCLA, and entered the job market in time for the Regan purge of EPA in 1981. His practice covered air, water and waste for basic industry, as well as small business. He has obtained NSR and air toxics permits for metals plants and has completed over 30 ERC transactions in support of NSR air permits. At A&WMA he is a Fellow Member, is in his seventh year on the International Board and has been recognized for achievement by the Board, the Education Council, and Sections & Chapters Council. Harry will be A&WMA president in 2026.
