The NCASI Air Program focuses on improving the science and implementation of emissions measurement methods–a topic that is relevant for forest products manufacturing and beyond. Leveraging this expertise on measurement methods, the program focuses on collecting and compiling reliable data on emissions from forest products manufacturing. Results from targeted NCASI and member company-generated emission studies are compiled and published in comprehensive emissions databases. This data is used to inform regulatory agencies and rulemakings, assist member companies during critical permitting activities, and advance industry understanding of operational factors affecting emissions. The Air Program also develops educational material on field implementation of emission test methods, air emissions databases and chemical reporting.

Focus Areas

Measurement & Analytical Methods

This focus area is oriented towards maintaining expertise in emission measurement and related analytical methods. NCASI expertise in this focus area is leveraged to evaluate, improve and modify EPA and other reference methods under both these categories, where applicable. One area of specific focus is on method performance on pulp…

Measuring Flue Gas CO2

Source & Ambient Characterizations

As more regulatory and permitting activities focus on assessing ambient impacts of source-level emissions, there is a need to better characterize/speciate both source-level and ambient monitor data and estimate the ambient impacts of source emissions. There is also a need to explore modeling approaches that “map” the constituents measured on…

Emission Monitors & Sensors

The role of continuous emission monitors (CEM) and continuous monitoring systems (CMS) continues to increase in regulatory compliance. New screening or monitoring tools are also being deployed to measure VOC, HAP and PM2.5 levels at fence-lines, generate screening level data on ambient impacts, and detect/measure fugitive emissions.
