||The objective of the project was to assist the electroplating and surface finishing industry identify and solve specific problems with completion of Form R - a required annual emissions report to the U.S. Environmental Protection Agency. The process selected for field characterization in the study was electroless copper plating. The sampling effort involved simultaneous quantification of fugitive emissions of formaldehyde (HCHO), and emissions of HCHO through existing tank ventilation systems that connect to a stack. The results of the research indicate that only about 10% of the formaldehyde purchased becomes an atmospheric release, with the dominant loss being consumptive reactions in the plating bath. The stack and fugitive losses of formaldehyde are of about equal magnitude. A predictive model for atmospheric releases was developed. Total (uncontrolled) emissions from the three plants evaluated ranged from about 20 to about 160 pounds per year, per plant.
