Public Health Assessment for Petitioned Public Health Assessment, Union Carbide(Byers Warehouse), St. Joseph, Buchanan County, Missouri, Region 7

摘要

In response to a petition from a St. Joseph, Missouri resident, the Agency forToxic Substances and Disease Registry (ATSDR) conducted a public health assessment of the Union Carbide (Byers Warehouse) site in St. Joseph, Missouri. The basement of Byers Warehouse was used by Vulcan Chemicals to store ethylene dibromide (EDB), chloroform, and carbon tetrachloride (CCI4). The first and second floors were used by Union Carbide to store 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), 2,4-dichlorophenoxyacetic acid (2,4-D), and 2,4,5-trichlorophenoxyproprionic acid (2,4,5-TP). The Byers Warehouse (Union Carbide) Petition site is not a current public health hazard. That conclusion is based on the complete removal of the toxic substances stored in the warehouse, and the lack of any current or future completed exposure pathways. Past storage of herbicides and other chemical products represented a public health hazard.
