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.
NCASI maintains comprehensive air emissions databases for air toxics and criteria pollutants (SO2, NOx, CO, particulate matter, and total VOCs) for pulp and paper mill sources. These databases incorporate data from emission studies carried out to inform the MACT rulemakings and other subsequent NCASI/industry testing.
