CORPORATE-WIDE IMPLEMENTATION OF PROCEDURES TO ESTIMATE SECONDARY EMISSIONS FROM WASTEWATER SYSTEMS
A Corporate-wide procedure was implemented at Union Carbide Corporation (UCC) for estimating secondary emissions from wastewater operations. The intent of utilizing a single corporate-wide approach was to have a common and consistent estimation procedure, and thus eliminate any uncertainty in emission estimates from plant site to plant site. This paper discusses the decisions made for selection of estimation procedures, use of common engineering design for modeling default values, application of models to “real” wastewater systems, and training needs to implement the approach. A separate review of chemical properties was done to create a defensible chemical database, with specific emphasis place on Henry's Law constants. Finally, results from UCC's Toxics Release Inventory (TRI) reporting from 5 different chemical facilities for the most recent three years show that secondary emissions are a minor component (∼5%) of the total emissions released to the atmosphere.
