Description:
The University of Central Florida Department of Civil and Environmental Engineering is investigating methods for improved estimation of chemical releases which require reporting under provisions of SARA Title III (Toxic Release Inventory, Form R).This paper describes results from a research project initiated in the Fall of 1990. The preliminary objective was to help the surface finishing industry to identify and solve specific problems with completion of Form R. A problem would generally be defined as a combination of a process (e.g., hard chrome plating) and a release (e.g., fugitive air releases of hexavalent chromium). It was concluded that the majority of environmental releases (water and sludges) are subject to some form of monitoring in conjunction with an operating permit. Accordingly, monitoring data is usually available to support completion of Form R. The principal exception to this generalization concerns air emissions, particularly fugitive emissions. The initial process selected for field characterization was hexavalent chromium releases from hard chrome plating. The sampling effort involved simultaneous quantification of fugitive emissions and emissions through existing tank ventilation systems into the stack.
