Emission Factors

Air Toxics

NCASI builds on an understanding of industrial processes, measurement methods and emissions measurement data to develop emission factors. Technical studies seek to fill critical gaps in emissions data in a timely manner, for maximum use in regulatory development and permitting. NCASI leverages this expertise to address challenging member questions related to emissions reporting, inventory development and permitting. Examples include estimating TRS emissions from pulping, emission factors for Hazardous Air Pollutants from industrial boilers and methods to estimate hydrogen sulfide emissions from wastewater treatment plant unit operations.
